This disclosure relates to a fluid container.

People use fluids for a multitude of reasons. For example, people consume beverages to hydrate themselves. The beverages can be stored in containers. For example, the containers can be portable so that the beverages are portable. Some portable containers are disposable.

The present systems and methods provide an easy to use, portable container to store fluids, e.g., beverages. For example, a portable container can include a disposable foil pouch that contains a beverage. The pouch can include a tear line that allows a user to tear the pouch open to access the beverage contained within the pouch. The tear line can be provided at a location on the pouch (e.g., a top corner of the pouch) that allows a user to easily drink the beverage. The pouch can also include a pierceable hole that is initially closed, but can be pierced to allow the user to insert a straw into the pouch. The pierceable hole can also be used as a vent so that the beverage can easily be poured after a user tears the pouch at the tear line. For example, air can enter the pierceable hole as the user pours the beverage from the pouch. This can be advantageous, e.g., because the beverage can be poured quickly and with little effort by the user.

The details of one or more embodiments of the subject matter described herein are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the subject matter will be apparent from the description and drawings, and from the claims.

Like reference numbers and designations in the various drawings indicate like elements.

The present systems and methods provide an easy to use, portable container to store fluids, e.g., beverages. For example, a portable container can include a disposable foil pouch that contains a beverage. The pouch can include a tear line (e.g., a perforated tear line) that allows a user to tear the pouch open to access the beverage contained within the pouch. The tear line can be provided at a location on the pouch (e.g., a top corner of the pouch) that allows a user to easily drink the beverage, empty the beverage into another container (e.g., a cup), etc. The pouch may include a front surface comprising a pierceable vent and a back surface, being opposite the front surface, wherein the back surface and the front surface are sealed together to form the fluid reservoir. The pierceable vent may be configured to allow air to enter the fluid reservoir as fluid is being removed from the fluid reservoir by an opening provided by the portion of the perforated portion being separated from the front surface and the back surface.

illustrates a fluid containerthat is formed by a flexible, disposable pouch. For example, the pouchcan be formed of, e.g., a metal foil material, plastics, a combination of one or more metals and one or more plastics, one or more layers of material, etc. For example, the material can have a nominal thickness of 4.7 mils, and hold approximately 5400 in/lb. Such materials include polyethylene terephthalate foil. In another example, the material can have a nominal thickness of 4.1 mils and have a seal strength of more than 4000 g/in. Such materials include aluminum foil. In implementations, the material can include multiple layers of material. Some examples of a pouch can be described in U.S. patent application Ser. No. 18/241,678, filed on Apr. 19, 2024, which claims priority U.S. Provisional Patent Application Ser. No. 63/461,222, filed on Apr. 21, 2023, the entire contents of each of which are hereby incorporated by reference.

The pouchcan be sized to hold a variety of fluids. For example, the pouchcan be sized to hold 5 ounces, 10 ounces, 15 ounces, etc. In some implementations, the pouch is sized to hold between 8 ounces and 10 ounces of fluid. In some implementations, the pouch is sized to hold between 9 and 10 ounces of fluid. In some implementations, the pouch is sized to hold between 8 and 20 ounces of fluid.

The pouchincludes a tear lineacross a top of the pouchto the opposite side of the pouch. The tear linecan include, e.g., a perforation in the pouch, a section of the pouchhaving thinner walls, etc. In some implementations, the tear linecan include a pre-made tear on at least a portion of a top cornerof the pouch. The pre-made tear can allow a user to more easily tear the corneroff the pouch. In some implementations, the tear linecan include a perforation (e.g., a series of holes that serves as an aid in separation). Different geometries of perforation can be used. For example, the holes can be, e.g., slits, circular holes, triangular holes, etc. The perforations can be formed by, e.g., pinner perforation rollers, die and punch, laser perforation, etc. The perforation creates a long series of slits so that the plastic can be torn easily along the tear line. Once the user tears the corneroff the pouch, the user can access the fluid (e.g., beverage) contained within the pouch. Because the tear lineextends all the way across the pouch, the user can tear both corners,off the pouchwith a single tear. As the user tears the pouch along the tear line, the pouch deforms and is configured to guide the tear linearly. This full tear of the top of the pouch allows the user increased access to the contents of the drink. This enables users to pour additional liquid into the pouch, or to add various desired ingredients to the pouch (e.g. liquid IV, vitamin C, water flavoring powder, etc.). This also allows users to easily pour the drink out into another container.

The pouchalso includes a pierceable hole. The holecan include, e.g., a perforation in the pouch, a section of the pouchhaving thinner walls, etc. to allow a user to easily pierce the hole, e.g., with a straw. In some implementations, the holehas a circular geometry (e.g., a 4 mm diameter, a 6 mm diameter, a diameter between 4 mm and 10 mm, a diameter between 1 mm and 10 mm, etc.); however, one or more other geometries maybe utilized (e.g., rectangular shapes, etc.). In the illustrated implementation, the tear line extends through the pierceable hole. In some implementations, the tear line is above the pierceable hole. In other implementations, the tear line is below the pierceable hole.

The pouchcan include indicia to indicate the location of the pierceable hole. For example, text on the pouchcan indicate the location of the hole. In some implementations, colors of the pouchcan indicate the location of the hole. In some implementations, the holecan act as a hole for a straw so that a user can drink the beverage through a straw. In some implementations, the holecan act as a vent. For example, the holecan act as a vent when a user tears the top corneroff the pouch. If the user wants to drink the beverage from the torn corner or pour the beverage from the top corner, the vent can allow air to enter the pouch. Allowing air to enter the pouch assists the user in drinking and pouring the beverage, so that little effort is required by the user.

The size, position, etc. of the holecan vary. For example, in some implementations, the holecan be located on a side of the pouch. In some implementations the holecan be larger, and in some implementations the holecan be smaller. In some implementations, the fluid containercan include multiple holes. The multiple holes can be similar or different from each other.

illustrates front view of the fluid container. The tear lineis presented normal to the view presented in. The tear linecan extend horizontally from a sideof the pouchto the opposite sideof the pouch. The tear linecan define a rectangular shaped portion in the cornerof the pouch. In the illustrated example, the tear lineextends horizontal from the side; however, the tear line may extend along other directions. For example, the tear linecan be extend perpendicular to the side(to account for a tapered geometry of the side) or in other angles relative to the side, for example, at 5 degree angle (upward or downward) relative to the side.

In some implementations, the surfaces near the tear line can be smooth, such that the user is comfortable placing his or her mouth on the pouch. For example, the tear line can be configured such that a smooth edge is left on the pouch. This can prevent a user from cutting his or her lips, fingers, etc. while drinking from the pouch.

The geometry of the pouchcan vary. In the illustrated embodiment, sides,of the pouch are not parallel. For example, the sides,are tapered. In some embodiments, the sides,are parallel. In some implementations, the sides,can include surface features (e.g., grips, features that increase friction, etc.) to assist a user with holding the pouch.

illustrates a back view of the fluid container. In the illustrated implementation, the back of the pouchdoes not include a pierceable hole; however, in some implementations, the back of the pouchincludes a hole similar to the hole. In some implementations having a hole on the back of the pouch, the hole on the back of the pouchcan be different than a hole on the front of the fluid container. In some implementations, the pouchcan have a hole on the back of the pouch, and the pouch does not have a hole on the front of the pouch. The back of the pouchalso includes a tear line. The tear linecan be similar to the tear linethat is on the front of the pouch, or the tear linecan be different from the tear line, as discussed further below.

illustrate a left side view of the fluid containerand a right side view of the fluid container, respectively. Tear lines,are illustrated in the left side view of the fluid container. As illustrated, the tear lineappears on a front sideand tear lineappears on a back sideof the fluid container to define rectangular shaped portions on the front surface and back surface of the pouch. This allows a user to easily tear through the front sideand the back sideof the pouch. In some implementations, the front side, the back side, other portions of the pouch, etc. can include surface features (e.g., grips, features that increase friction, etc.) to assist a user with holding the pouch. Although the tear lines,are illustrated as symmetric, in some embodiments, the tear lines can be different (e.g., asymmetric). For example, the tear linecan extend a different distance than the tear line. In some implementations, the tear line, the tear line, or both of the tear lines,can be curved. For example, the same, similar, or different curves can be used on the front and back tear lines. For example, the front tear linecan have a particular curve (e.g., having a particular radius) and the back tear linecan have a same curve rotated at 10 degrees. As illustrated in, the pre-made tear appears on a right side view of the pouch. This allows a user to easily tear through the front and back side of the pouch.

When filled with liquid, the pouchis thicker at a bottomof the pouch than at the topof the pouch. The weight distribution of the liquid contained within the pouchallows the pouch to stand upright, e.g., so that liquid does not spill from the holeor an open corner of the pouch. The pouchbecomes flatter as liquid is removed from the pouch. Because the pouchis flexible, a user can easily deform the pouchto a desired shape. For example, the user can squeeze the pouchto remove liquid from the pouchat a faster rate.

illustrates a top view of the fluid container. The holeis visible on the front sideof the pouch. In some implementations, the holeis closer to the topof the pouchor closer to one of the sides,of the pouch. In some implementations, the front sideand the back sideextend a smaller distance from the center of the pouch, e.g., to form a thinner pouch. As discussed above, the weight distribution of the pouch can be designed, e.g., to allow the pouch to stand upright.

illustrates a bottom view of the fluid container. The pouchincludes two lips,that form a base extending from the bottom of the pouchto stand the pouchupright. The front lipextends forming a front base portion on the front sideof the pouch and the back lipextends from the back sideof the pouch to form a back base portion of the pouch. The bottom of a reservoirof the pouch is surrounded by the two lips,. The bottom of the reservoircan have varying geometries (e.g., a domed geometry) based on the amount of fluid in the reservoir. For example, the geometry of the reservoircan change as the amount of fluid in the containerchanges. In some embodiments, the bottom of the reservoircan fold (e.g., in half) as the amount of fluid in the containerchanges. The lips,extending from the bottom of the pouchand surrounding the bottom of the reservoircan provide a stable surface for the pouchto stand upright regardless of the geometry of the bottom of the reservoir. In some implementations, the front lipextends an inch, 1.5 inches, or two inches past the bottom of the reservoir. In some implementations, the back lipextends an inch, 1.5 inches, or two inches past the bottom of the reservoir. The lips can also extend different distances past the bottom of the reservoir. In some implementations, the bottom of the reservoircan be made of a different material than the two lips,. In some implementations, the bottom of the reservoircan be formed of a clear or translucent material, e.g., to allow a user to see the fluid within the container. In some implementations, the geometry of the bottom of the reservoir can be an ogive curve. In some embodiments, the two lips,can be curved to provide a stable surface. In some implementations, the bottom of the reservoirhas a different thickness than other portions of the container. For example, the bottom of the reservoircan be thicker than the front sideand the back sideof the pouch. The bottom of the reservoircan be thicker than the two lips,. In some implementations, a thicker bottom can hold more weight (e.g., hold more fluid) than a thinner bottom. In some implementations, the bottom of the reservoircan have a thickness that is constant across the bottom of the reservoir.

illustrates a fluid containerthat is formed by a flexible, disposable pouch. For example, the pouchcan be formed of a material similar to that of pouchof, e.g., a metal foil material, plastics, a combination of one or more metals and one or more plastics, one or more layers of material, etc.

The pouchcan be sized to hold a variety of fluids. For example, the pouchcan be sized to hold 5 ounces, 10 ounces, 15 ounces, etc. In some implementations, the pouch is sized to hold between 8 ounces and 10 ounces of fluid. In some implementations, the pouch is sized to hold between 9 and 10 ounces of fluid. In some implementations, the pouch is sized to hold between 8 and 20 ounces of fluid.

The pouchincludes a pre-made tearon a side of the pouch below the top cornerof the pouch. The pre-made tearcan include, e.g., a tear that extends approximately half-way from the outside of a smooth edge of the pouchto an edge of the liquid reservoir within the pouch(e.g., 2 mm, 1-4 mm, etc.). The pre-made tearcan include, e.g., perforations that extend approximately half-way from the outside of the smooth edge of the pouchto an edge of the liquid reservoir within the pouch. The pre-made tear can allow a user to more easily tear the corneroff the pouch. Once the user tears the corneroff the pouch, the user can access the fluid (e.g., beverage) contained within the pouch. The pouchmay also include a pre-made tearin the side of the pouch opposite to tear line, such that the tear lineis approximately parallel to the pre-made tear, and such that the tear lineand the pre-made tearare located at approximately the same distance from the top of the pouch. The pre-made tear extends approximately half-way from the outside of a smooth edge of the pouchto an edge of the liquid reservoir within the pouch. The tear lineand pre-made tearare aligned such that tearing the tear linemay allow a user to tear the top of the pouch entirely from the pre-made tearto the pre-made tear, or vice versa. As the user tears the pouch along the pre-made tear, the pouch deforms and is configured to guide the tear linearly to connect to the pre-made tear. This full tear of the top of the pouch allows the user increased access to the contents of the drink. This enables users to pour additional liquid into the pouch, or to add various desired ingredients to the pouch (e.g. liquid IV, vitamin C, water flavoring powder, etc.). This also allows users to easily pour the drink out into another container.

The pouchalso includes a pierceable hole. The holecan include, e.g., a perforation in the pouch, a section of the pouchhaving thinner walls, etc. to allow a user to easily pierce the hole, e.g., with a straw. In some implementations, the holehas a circular geometry (e.g., a 4 mm diameter, a 6 mm diameter, a diameter between 4 mm and 10 mm, a diameter between 1 mm and 10 mm, etc.); however, one or more other geometries maybe utilized (e.g., rectangular shapes, etc.). In the illustrated implementations, the pre-made tears,are aligned with the pierceable hole. In other implementations, the pre-made tears can be aligned above or below the pierceable hole. In some implementations, the pierceable holeincludes concentric circles of perforations. For example, the pierceable holecan include a perforation at the center of the concentric circles, and each circle of the concentric circles can provide a weakness in the pouchto allow a user to easily pierce the hole. In some implementations, each circle of the concentric circles can be raised relative to the pouch. In some implementations, the concentric circles can contain the hole, e.g., and guide a user to pierce the hole without further tearing of the pouchaway from the hole. For example, in some implementations, each circle of the concentric circles can be a thicker material than other portions of the pouch. In some implementations, the perforations of the pierceable holecan be different than perforations of the pre-made tears,.

The pouchcan include indicia to indicate the location of the pierceable hole. For example, text on the pouchcan indicate the location of the hole. In some implementations, colors of the pouchcan indicate the location of the hole. In some implementations, the holecan act as a hole for a straw so that a user can drink the beverage through a straw. In some implementations, the holecan act as a vent. For example, the holecan act as a vent when a user tears the top corneroff the pouch. If the user wants to drink the beverage from the torn corner or pour the beverage from the top corner, the vent can allow air to enter the pouch. Allowing air to enter the pouch assists the user in drinking and pouring the beverage, so that little effort is required by the user.

The size, position, etc. of the holecan vary. For example, in some implementations, the holecan be located on a side of the pouch. In some implementations the holecan be larger, and in some implementations the holecan be smaller. In some implementations, the fluid containercan include multiple holes. The multiple holes can be similar or different from each other.

The pre-made tearcan define a rectangular shaped portion in the cornerof the pouch. The pre-made tearis presented normal to the view presented in. The pre-made tear can extend horizontally from a sideof the pouch. As discussed above, the pre-made tear is located at approximately the same distance from the top of the pouch as the pre-made tear. In some implementations the pre-made tearcan be positioned at a distance from the top of the pouchthat is larger or smaller compared to the distance that the pre-made tearis positioned from the top of the pouch. In the illustrated example, the pre-made tearhas extends horizontal from the side; however, the pre-made tear may extend along other directions. For example, the pre-made tearcan extend perpendicular to the side(to account for a tapered geometry of the side) or in other angles relative to the side, for example, at 5 degree angle (upward or downward) relative to the side.

The back of the pouchalso includes a pre-made tear. This allows a user to easily tear through the front and back side of the pouch and allows the use to tear either from the tear lineto the pre-made tear, or vice versa.

As illustrated in, the pre-made tearappears on a right side view of the pouch. This allows a user to easily tear through the front and back side of the pouch and allows the use to tear either from the tear lineto the pre-made tear, or vice versa.

The lips,can be similar to the lips,ofabove. The lips,extending from the bottom of the pouchand surrounding the bottom of the reservoircan provide a stable surface for the pouchto stand upright regardless of the geometry of the bottom of the reservoir. In some implementations, the front lipextends an inch, 1.5 inches, or two inches past the bottom of the reservoir.

In some implementations, a thicker bottom can hold more weight (e.g., hold more fluid) than a thinner bottom. In some implementations, the bottom of the reservoircan have a thickness that is constant across the bottom of the reservoir.

illustrates an engineering drawing of a fluid container. The fluid containercan be similar to, e.g., the fluid containerof. The fluid containeris formed by a flexible, disposable pouch. The pouchcan be a metal foil material, e.g., including aluminum, tin, copper, etc. In some implementations, the pouchcan include plastics, e.g., including polyvinylidene chloride (PVC), low-density polyethylene (LDPE), etc. In some implementations, the pouchcan be formed of a combination of metals and plastics.

The pouchincludes a front paneland a back panel. When the front paneland the back panelare sealed together, they form a reservoirthat can contain fluid, e.g., a beverage. For example, a sealsurrounding the reservoircan seal the front panelto the back panel. Additional foil materialcan be included on the bottom of the reservoir, e.g., to provide a surface for the pouchto stand upright, as discussed above. In some implementations, a trimsurrounds the pouchduring manufacturing. The trimcan be removed after or during the manufacturing process and does not remain on the finished product.

The pouchincludes a pre-made tearin a portion of the seal. For example, the pre-made tear provides a beginning for the user to tear a corner off the pouch. The user therefore does not have to use a lot of effort to start the tear in the corner, as discussed above. The reservoirremains sealed until a user tears off a portion of the pouch. This can allow a user to easily transport the containerwithout spilling the fluid in the container. In some implementations, the pre-made tearis about 25 millimeters (mm) from the top of the pouch. In this embodiment, the pre-made tearextends perpendicularly across a portion of the front panel, e.g., creating a rectangular portion of the front panel. In some implementations, the pre-made tear can extend different distances across the panels. In the illustrated implementation, the pre-made tearextends the same distance as a second pre-made tearin an opposite side of the panel.

The pouchincludes a pierceable holein the front panel. The holecan be similar to the holeof. The holecan include, e.g., a perforation in the pouch, a section of the pouchhaving thinner walls, etc. to allow a user to easily pierce the hole, e.g., with a straw, toothpick, etc. The pouchcan include indicia to indicate the location of the pierceable hole. For example, text on the pouchcan indicate the location of the hole. In some implementations, colors of the pouchcan indicate the location of the hole. In some implementations, the holecan act as a hole for a straw so that a user can drink the beverage through a straw. In some implementations, the holecan act as a vent. For example, the holecan act as a vent when a user tears the top corner off the pouch, e.g., using the pre-made tear. If the user wants to drink the beverage from the torn corner or pour the beverage from the top corner, the vent can allow air to enter the pouch. Allowing air to enter the pouch assists the user in drinking and pouring the beverage, so that little effort is required by the user. The holecan have a diameter in a range of about 1 mm to about 10 mm (e.g., 6 mm, 4 mm, 2 mm, etc.). In some implementations, the holeis about 25 mm from the top of the pouch. For example, the center of the holeis about 25 mm from the top of the pouch.

The pouchcan generally have a width in a range of about 100 mm to about 150 mm (e.g., 111 mm as illustrated, 105 mm). The pouch can have a height in a range of about 150 mm to about 300 mm (e.g., 15 mm as illustrated). The pouchcan also have heights and widths outside of these ranges. In some implementations, the sealcan have a width in a range of about 3 mm to about 10 mm (e.g., 6 mm as illustrated). The thickness of the pouchcan vary depending on the amount of liquid in the pouch. In some implementations, the thickness of the pouchcan be in a range of about 60 mm to about 65 mm.

In some implementations, a trimsurrounds the pouchduring manufacturing. The trimcan be removed after or during the manufacturing process and does not remain on the finished product. The trimcan have a width of, e.g., between 1 mm to 5 mm, such as 3 mm.

illustrates an engineering drawing of a gussetfor forming the bottom of a fluid container. For example, the gussetcan be used to form the bottom of the reservoirof the pouch, illustrated in. The gussetis formed by a flexible, disposable material, e.g., a metal foil material, e.g., including aluminum, tin, copper, etc. In some implementations, the materialcan include plastics, e.g., including polyvinylidene chloride (PVC), low-density polyethylene (LDPE), etc. In some implementations, the materialcan be formed of a combination of metals and plastics.

The gussethas a width in a range of about 50 mm to about 100 mm (e.g., 74 mm as illustrated). The pouchhas a height in a range of about 75 mm to about 150 mm (e.g., 105 mm as illustrated). The gusset can also have heights and widths outside of these ranges. The gussetcan include a trimthat surrounds the gussetduring manufacturing. The trimcan be removed after or during the manufacturing process and does not remain on the finished product. The trimcan have a width of, e.g., between 1 mm to 5 mm, such as 3 mm or 5 mm.

illustrates an engineering drawing of another gussetfor forming the bottom of a fluid container. For example, the gussetcan be used to form the bottom of the reservoirof the pouch, illustrated in. The gussetis formed by a flexible, disposable material, e.g., a metal foil material, e.g., including aluminum, tin, copper, etc. In some implementations, the materialcan include plastics, e.g., including polyvinylidene chloride (PVC), low-density polyethylene (LDPE), etc. In some implementations, the materialcan be formed of a combination of metals and plastics.

The gussetcan be twice as large as the gusset, e.g., and can be used to form two gussets the size of the gusset. For example, the gussethas a width in a range of about 100 mm to about 200 mm (e.g., 143 mm as illustrated). The gussethas a height in a range of about 75 mm to about 150 mm (e.g., 105 mm as illustrated). The pouch can also have heights and widths outside of these ranges. The gussetcan include a trimthat surrounds the pouchduring manufacturing. The trimcan be removed after or during the manufacturing process and does not remain on the finished product. The trimcan have a width of, e.g., between 1 mm to 5 mm, such as 3 mm or 5 mm.

While not described in the figures, an additional embodiment of the pouch may include two or more compartments within the pouch. This enables the pouch to hold different sets of liquids and enables users to mix or keep the liquids separate. Each compartment within the pouch may include a separate venting hole and perforation line, such that a user may separately pour out the liquid contents of each compartment. Users may also use a straw to drink out of the venting hole in each compartment.

A number of embodiments have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the disclosure. Accordingly, other embodiments are within the scope of the following claims.
