Straw cup

The disclosure relates to the field of cups, in particular to a straw cup.

A straw cup is a container used for drinking water, coffee, milk tea, and other beverages. The commonly seen straw cups on the market now have a suction nozzle. Most of them, as disclosed in a utility model patent with a suction nozzle cup lid (publication number: CN214803963U), have a suction nozzle that can be rotated and connected to the cup lid. The side of the suction nozzle is fixed with a locking block, and the cup lid is fixed with a locking groove. When the suction nozzle is stored relative to the cup lid, it is locked by the locking block and the locking groove. When people want to drink, they need to hold the cup with one hand and move the suction nozzle with the other hand to detach the locking block from the locking groove, allowing the suction nozzle to flip to the unfolded state. The operation is not complicated. Convenient, not suitable for drinking while driving.

In view of the defects in the prior art, the disclosure provides a straw cup, comprising a cup body and a cup lid covering the cup body, wherein the cup lid comprises: a cup lid body, comprising a lid structure and a handle structure connected to the lid structure; a sippy spout assembly, rotatably connected to the lid structure and having a closed state of being folded relative to the lid structure and an open state of being unfolded relative to the lid structure, the sippy spout assembly being provided with a first locking portion; a transmission structure, provided with a second locking portion arranged corresponding to the first locking portion, the sippy spout assembly being kept in the closed state by making the first locking portion fitted with the second locking portion, and the sippy spout assembly being allowed to switch to the open state by unfitting the first locking portion and the second locking portion; and an operating structure, mounted on the handle structure, connected with the transmission structure in a transmission way, and capable of moving relative to the handle structure to drive the transmission structure to move until the second locking portion is away and unfitted from the first locking portion.

According to the straw cup provided by the disclosure, the sippy spout assembly is kept in the closed state of being folded relative to the lid structure by making the second locking portion on the transmission structure fitted with the first locking portion on the sippy spout assembly. The second locking portion moves relative to the sippy spout assembly along with the transmission structure. Before drinking, the operator only needs to drive the operating structure to move relative to the handle structure by hand so as to drive the transmission structure and the second locking portion arranged on the transmission structure to be away and unfitted with the first locking portion, so that the sippy spout assembly is allowed to switch to the open state, which is simple to operate and convenient to use. Moreover, compared with the unlocking structure of manually pulling the fixed locking block to slide over the fixed locking groove directly in the prior art, the disclosure undoes the fit by making the movably arranged second locking portion move away from the first locking portion, which greatly reduces the friction produced between the second locking portion and the first locking portion in the unlocking process, prolongs the service life of the first locking portion and the second locking portion and makes the straw cup more durable. In addition, the sippy spout assembly is rotatably connected to the lid structure, and the operating structure is mounted on the handle structure, so that the operator can hold the whole straw cup by grasping the handle structure and drive the operating structure to move relative to the handle structure while grasping the handle structure. In this way, while the operator holds the straw cup with one hand, the sippy spout assembly is allowed to switch to the open state. Thereby, the straw cup is simple and convenient to operate, and is especially convenient to use during driving, thereby having high practicability.

In order to clarify the purpose, technical solution, and advantages of the embodiments of the present invention, the following will provide a clear and complete description of the technical solution of the embodiments of the present invention in conjunction with the accompanying drawings.

As shown into, an example of the disclosure provides a straw cup, including a cup bodyand a cup lidcovering the cup body. The cup lidincludes a cup lid body, a sippy spout assembly, a transmission structureand an operating structure. The cup lid bodyincludes a lid structureand a handle structureconnected to the lid structure. The sippy spout assemblyis rotatably connected to the lid structureand has a closed state of being folded relative to the lid structureand an open state of being unfolded relative to the lid structure. The sippy spout assemblyis provided with a first locking portion. The transmission structureis provided with a second locking portionarranged corresponding to the first locking portion. The sippy spout assemblyis kept in the closed state by making the first locking portionfitted with the second locking portion, and the sippy spout assemblyis allowed to switch to the open state by unfitting the first locking portionand the second locking portion. The operating structureis mounted on the handle structure, connected with the transmission structurein a transmission way, and capable of moving relative to the handle structureto drive the transmission structureto move until the second locking portionis away and unfitted from the first locking portion. According to the straw cup of this example, the sippy spout assemblyis kept in the closed state of being folded relative to the lid structureby making the second locking portionon the transmission structurefitted with the first locking portionon the sippy spout assembly. The second locking portionmoves relative to the sippy spout assemblyalong with the transmission structure. Before drinking, the operator only needs to drive the operating structureto move relative to the handle structureby hand so as to drive the transmission structureand the second locking portionarranged on the transmission structureto be away and unfitted with the first locking portion, so that the sippy spout assemblyis allowed to switch to the open state, which is simple to operate and convenient to use. Moreover, compared with the unlocking structure of manually pulling the fixed locking block to slide over the fixed locking groove directly in the prior art, the disclosure undoes the fit by making the movably arranged second locking portionmove away from the first locking portion, which greatly reduces the friction produced between the second locking portionand the first locking portionin the unlocking process, prolongs the service life of the first locking portionand the second locking portionand makes the straw cup more durable. In addition, the sippy spout assemblyis rotatably connected to the lid structure, and the operating structureis mounted on the handle structure, so that the operator can hold the whole straw cup by grasping the handle structureand drive the operating structureto move relative to the handle structurewhile grasping the handle structure. In this way, while the operator holds the straw cup with one hand, the sippy spout assemblyis allowed to switch to the open state. Thereby, the straw cup is simple and convenient to operate, and is especially convenient to use during driving, thereby having high practicability.

As shown into, in some specific examples, the first locking portionhas a first locking surface, and the second locking portion has a second locking surface. The first locking portionand the second locking portionare fitted by making the second locking surfaceabut against an upper side of the first locking surface(for example, the first locking surfaceis arranged at a free end of the sippy spout assemblyor close to the free end of the sippy spout assembly, so that the sippy spout assemblyis prevented from rotating from the closed state to the open state by making the second locking surfaceblock the upper side of the first locking surface), and unfitted by making the second locking surfaceseparated from the first locking surface. In other examples, the first locking portionand the second locking portionmay also fitted by making the second locking surfaceabut against a lower side of the first locking surface. For example, the first locking surfaceis arranged at the rotatable connection position of the sippy spout assemblyor at an end of the rotatable connection position away from the free end of the sippy spout assembly, so that the sippy spout assemblyis prevented from rotating from the closed state to the open state by making the second locking surfaceblock the lower side of the first locking surface.

As shown in, in some specific examples, the first locking portionis arranged at a side of the sippy spout assemblyaway from the operating structure, and the transmission structuremoves between a first locked position close to the operating structureand a first unlocked position close to the sippy spout assembly. When the transmission structureis in the first locked position and the sippy spout assemblyis in the closed state, the second locking surfaceabuts against the upper side of the first locking surface; and when the transmission structureis in the first unlocked position and the sippy spout assemblyis in the open state, the second locking surfaceis separated from the first locking surfaceand arranged at a side of the first locking surfaceaway from the operating structure. In this way, the transmission structureis driven by the operating structureto move from the first locked position toward the first unlocked position, and also drives the second locking surfaceto move toward a side of the first locking surfaceaway from the operating structureuntil it is separated from the first locking surfaceso as to unfit the second locking portionand the first locking portion. In this example, the first locking portionis arranged at the side of the sippy spout assemblyaway from the operating structure, which makes the space for arranging the lid structureand the sippy spout assemblycompact. In other examples, the first locking portionmay also be arranged at the lower side of the sippy spout assemblyso as to improve the reliability of connection between the sippy spout assemblyand the transmission structure.

As shown in, in some specific examples, the second locking portionincludes a second connecting blockarranged along a height direction and a second locking blockconnected to an upper end of the second connecting block, and the second locking blockprotrudes from a side of the second connecting blockclose to the operating structureso as to form the second locking surfaceat a bottom surface of the second locking block. It is defined that the sippy spout assemblyin the closed state is in the horizontal direction and the height direction is a direction perpendicular to the horizontal direction, which is beneficial to the stable connection between the first locking portionand the second locking portion.

As shown in, in some specific examples, an arrangement direction of the transmission structureis perpendicular to an arrangement direction of the sippy spout assembly. The sippy spout assemblyincludes a straw member, a sippy spout memberconnected to a free end of the straw member, and a sippy spout sleevesleeved outside the straw memberand arranged close to an end of the sippy spout memberaway from a free end of the sippy spout member. The first locking portionis provided as a recess structure recessed from a side of the sippy spout sleeveaway from the operating structure. A bottom surface of the recess structure forms the first locking surface. The second locking portionextends its second locking blockinto the recess structure to make the second locking surfaceabut against the upper side of the first locking surface, so that the first locking portiondoes not need to occupy additional arrangement space, which makes the arrangement space more compact. When the sippy spout assemblyis in the closed state, the sippy spout sleevedrives the straw memberto be folded relative to the lid structureso as to close the drinking channel.

In other examples, the first locking portionmay also be provided as a hook structure, which may be arranged at a side of the sippy spout sleeveaway from the operating structureor at a bottom side of the sippy spout sleeve. In both cases, the first locking portion can be fastened with the second locking portion.

As shown inand, in some specific examples, a top of the lid baseis concavely provided with a sinking groove. The base plate Iincludes a plate portion Iarranged in the sinking grooveand a plate portion IIarranged at a top of a side wall of the sinking groove. A shape of the base plate Iis matched with that of the sinking groove, which is beneficial to the stable connection between the base plate Iand the lid base. The enclosure plate Iand the enclosure plate IIIare connected to the plate portion I. The enclosure plate IIis connected to the plate portion II. The plate portion IIis connected to a side of the plate portion Iclose to the handle structure, which is convenient for the arrangement of the second transmission member. The second transmission memberincludes a transmission rod Islidably connected in the first transmission channeland a transmission rod IIconnected to an end of the transmission rod Iclose to the sippy spout assembly. The transmission rod IIis arranged in the sinking groove. When the transmission structuremoves to the first locked position close to the operating structure, the transmission rod IIabuts against a side wall of the sinking grooveso as to be limited. The second openingis provided as an L-shaped hole structure provided in both the plate portion Iand the plate portion II, which provides a movement channel for the transmission rod IIto run through the base plate Iand abut against the side wall of the sinking groove.

In some specific examples, the enclosure plate IIIhas an accommodating groovetherein for accommodating the sippy spout assembly. The accommodating grooveis communicated with the third transmission channel. The accommodating grooveis arranged perpendicular to the third transmission channel. The third transmission channelincludes a channel I arranged below the accommodating grooveand a channel II arranged at a side of the accommodating grooveaway from the operating structure. The first transmission memberis arranged in the channel I, and the second connecting blockis arranged in the channel II. The second connecting blockis connected to an upper side of the first transmission memberat an end away from the operating structure. The second locking portionis capable of moving with the second connecting blockand the first transmission memberunder the elasticity of the first return memberto extend into the accommodating groovealong the first direction A and form a snap fit with the first locking portionon the sippy spout assembly, and returning, when the operator presses the operating structure, into the channel II accommodated at the side portion of the accommodating grooveas the second connecting blockand the first transmission membermove along the second direction B. A top of the enclosure plate IIIand the lid cover plateare respectively correspondingly provided with a flip channelfor the sippy spout assemblyto switch between the open state and the closed state.

As shown in, in some specific examples, the handle structureincludes a handle connecting portionconnected to the side portion of the lid structurealong the first direction A, and a handle holding portionconnected with the handle connecting portion, and the operating structureis arranged on the handle connecting portion, which conforms to the human body structure and is convenient for holding the handle connecting portionwhile pressing the operating structure. In other examples, the operating structuremay also be arranged on the handle holding portion. The operating structureincludes an operating portionand a first transmission portionconnected to the operating portion. The handle connecting portionis provided with an operating channelarranged corresponding to the operating portion. The transmission structureincludes a second transmission portionarranged at a side of the first transmission portionclose to the sippy spout assembly. The second transmission portionis connected to an end of the transmission rod Iclose to the operating structure. An arrangement direction of the second transmission portionforms an acute angle with the second direction B. That is, a vertical distance between the second transmission portionand the sippy spout assemblygradually decreases from the end away from the operating structureto the end close to the operating structure. The operating direction of the operating structure, the second direction B and the arrangement direction of the second transmission portionare not parallel with each other. When the operator applies force to the operating portionalong the operating direction, the transmission structureis pushed to move along the second direction B to unlock the first locking portionand the second locking portionby making the first transmission portionabut against the second transmission portionand move along a surface of the second transmission portion. In this example, since the operating direction of the operating structureis different from the movement direction of the transmission structure, the operating direction may be set to an angle and direction suitable for the human hand to press, so that the operator can press the operating structureconveniently. In other examples, the movement direction of the operating structuremay be set to be the same as the movement direction of the transmission structure, so that when the operator presses the operating structurealong the operating direction, the first locking portionand the second locking portioncan be unfitted by making the first transmission portionabut against the second transmission portionand further pushing the transmission structureto move close to the sippy spout assembly.

As shown in, in some specific examples, the operating portionand the handle connecting portionare rotatably connected by means of a second rotating shaft. The operating direction is arranged along a circumferential direction of the second rotating shaft. The second rotating shaftis arranged at an end of the operating portionclose to the sippy spout assembly, and the first transmission portionis arranged at an end of the operating portionaway from the sippy spout assembly. When the operator presses the operating structurealong the operating direction to rotate along the circumferential direction of the second rotating shaft, the first transmission portionrotates along the circumferential direction of the second rotating shaftalong with the operating structure, and at the same time, the first transmission portionabuts against the second transmission portionand moves along the surface of the second transmission portiontoward an end of the second transmission portionaway from the sippy spout assembly, so as to push the transmission structureto move along the second direction B until the first locking portionand the second locking portionare unfitted. According to the lever principle, the second rotating shaftis arranged at the end of the operating portionclose to the sippy spout assembly, so that the operating structureis mounted onto the handle connecting portionby means of the second rotating shaft, which is easier and more labor-saving to use. In other examples, the second rotating shaftmay also be arranged at a middle part of the operating portion. As another example of the disclosure, there may be no second rotating shaftprovided. Instead, the operating portionis retractably connected in the operating channel, and the operating direction is arranged along the extension and retraction direction, which can also be used for mounting the operating structure.

As shown inand, in some specific examples, the handle structureincludes a second pedestalarranged therein. A second transmission channelruns through the second pedestal. The transmission structureis slidable along the second transmission channelso as to move between the first locked position of being locked relative to the sippy spout assemblyand the first unlocked position of being unlocked relative to the sippy spout assembly. Moreover, the transmission structureis guided to slide along the first transmission channeland the second transmission channel, which further improves the stability of the movement of the transmission structure. A second return memberfor driving the operating structureto return after moving along the operating direction is mounted between an inner wall of the operating structureand the second pedestal, which is used for realizing automatic return of the operating structureand making preparations for the next press operation. The second return membermay be provided as a compression spring, or elastic silicone or another structure arranged between the inner wall of the operating portionand the second pedestal. The inner wall of the operating portionis convexly provided with a positioning platform Iconfigured to be positioned and connected with one end of the second return member, and an outer wall of the second pedestalis convexly provided with a positioning platform IIconfigured to be positioned and connected with the other end of the second return member.

As shown in, in some specific examples, the cup bodyincludes a first cup body structure, a second cup body structureand a third cup body structureconnected between a lower end of the first cup body structureand an upper end of the second cup body structure. The second cup body structurehas an outer diameter less than that of the first cup body structureso as to be positioned and connected with an external placement medium, such as a vehicle-mounted water cup placement groove, which improves the stability of the placement of the straw cup. The cup lidis detachably connected to an upper end of the first cup body structure. A free end of the handle structureis arranged toward the lower end of the first cup body structure. An arrangement height of a lower end of the handle structureis greater than an arrangement height of an upper end of the first cup body structure, or the arrangement height of the lower end of the handle structureis greater than an arrangement height of an upper end of the third cup body structure, which avoids interfering with the positioning of the straw cup on the external placement medium.

As shown in, in some specific examples, a tube memberis arranged in the cup body. The tube memberis butted with a lower end of the straw memberof the sippy spout assembly, and configured to introduce the liquid in the cup bodyinto the sippy spout assembly. An outer peripheral side of a lower part of the lid baseis provided with an external thread structure, and an inner peripheral side of the upper end of the first cup body structureis provided with an internal thread structure. The cup lidand the cup bodyform a thread fit by means of the external thread structurethe internal thread structure, which is stable in connection, convenient to mount and demount and also convenient to clean. A bottom of the lid baseis provided with a first pressure relief channelarranged in vertical direction, and a side wall of the lower part of the lid baseis provided with a second pressure relief channelcommunicated with the first pressure relief channel. The first pressure relief channelis provided with a one-way valve. When the operator sucks the sippy spout assembly, a negative pressure is formed in the cup body, and the one-way valveopens the first pressure relief channelunder the action of the negative pressure, thereby allowing outside air to enter the cup bodyand making the operator suck water easily. When the operator stops sucking, the one-way valvecloses the first pressure relief channel, thereby avoiding water leakage.

As shown into, in some specific examples, the straw cup further includes a second locking structure. The second locking structureis mounted on the handle structureand arranged corresponding to the operating structure, and the second locking structureis capable of switching between a second locked position of preventing the operating structurefrom moving toward the operating direction and a second unlocked position of allowing the operating structureto move toward the operating direction, which prevents the sippy spout assemblyfrom being opened by accidental pressing when the straw cup is not in use, and improves the safety. The second locking structureis arranged on the handle connecting portion, which conforms to the human body structure, so that the second locking structurecan be operated to switch between the second locked position and the second unlocked position while the handle connecting portionis held.

As shown inand, in some specific examples, a side of the operating structureclose to the transmission structureis provided with a third locking portionand an unlocking groovearranged adjacent to each other, and the positioning platform Iis arranged in the unlocking groove. The second locking structureincludes a locking operating portionslidably connected to the handle structureand a fourth locking portionconnected to an inner side of the locking operating portion. When the second locking structureis in the second locked position, the operating structureis prevented from moving toward a press operation direction by making the fourth locking portionabut against the third locking portion, which can avoid opening the sippy spout assemblyby accidentally pressing the operating structure. When the second locking structureis switched to the second unlocked position, the operating structureis allowed to move toward the press operation direction by making the fourth locking portionaccommodated in the unlocking groove, and thereby, the operating structurecan move toward the operating direction to open the sippy spout assembly. The locking operating portionincludes a locking operating platearranged between the inner wall of the handle structureand the second pedestal, and a locking operating buttonconvexly provided at an outer side of the locking operating plate. The fourth locking portionis convexly provided at an inner side of the locking operating plate. The handle structureis provided with a locking channelarranged along the first direction A. The locking operating buttonruns through the locking channeland out of the outer side of the handle structuresuch that the operator can contact and apply force on it.
