DETAILED DESCRIPTION

[0023] The utility model provides a kind of multi-internal bladder multifunctional vacuum cup, for example typically three internal bladder design, solve the problem of single function or multi-internal bladder vacuum cup inconvenient to use of existing vacuum cup, on the basis of retaining the basic heat preservation function of vacuum cup, the vacuum internal bladder of cup body can be respectively filled with water or beverage of different temperature. Beverage temperature in each internal bladder is independent of each other, and does not affect each other, so that users can conveniently enjoy beverages of different temperature in the same container, providing great convenience for users.

[0024] Please refer to Figure 1 、 Figure 3 The utility model provides a kind of multi-internal bladder multifunctional vacuum cup, including cup body 6 and cover body, cover body is fixedly connected or movably connected / detachable connection with cup body 6, usually, cover body is movably connected / detachable connection with cup body 6, for example flip cover or screw cover type. In the scheme, cover body includes upper cup cover 1, middle cup cover 2 and lower cup cover 3 arranged from top to bottom, and upper cup cover 1 and middle cup cover 2 are movably connected or detachably connected, and middle cup cover 2 and lower cup cover 3 are movably connected or detachably connected, so as to realize opening and closing. Lower cup cover 3 is directly or indirectly connected with cup body 6.

[0025] Cup body 6 has two or more than two internal bladders inside, for example two or three or more, each internal bladder has a space for containing beverage respectively. Lower cup cover 3 is provided with straight drinking mouth 41 and straw 42, and straight drinking mouth 41 and straw 42 are respectively corresponding to different internal bladders, and lower cup cover 3 and internal bladder have sealing structure to seal each internal bladder and form sealing between each internal bladder and lower cup cover 3. It also includes straight drinking sealing part 51 for closing the upper end of straight drinking mouth 41 in closed state, so as to help heat preservation effect and prevent water leakage.

[0026] The lower end of straw 42 extends into the corresponding internal bladder (the part extending into the internal bladder can also be called straw lower section), and the upper end of straw 42 is connected with straw middle section 421 which can be bent and / or telescopic, and straw middle section 421 is located between lower cup cover 3 and middle cup cover 2. Middle cup cover 2 is provided with straw upper section 422, and the upper end of straw middle section 421 is connected with straw upper section 422. Straw 42, straw middle section 421 and straw upper section 422 can be selected as integral structure or split structure, in any case, a sealed passageway for sucking beverage can be formed. And because straw middle section 421 is deformable, middle cup cover 2 can be opened, and the whole straw is still in the state of not communicating with the outside in the opened state. Figure 4The straight drinking port 41 is shown to avoid the corresponding beverage of the straw from leaking out when the straight drinking port 41 is used. The straw sealing part 52 is further included to seal the upper section 422 of the straw in the closed state, thereby helping the insulation effect and avoiding the water leakage. The straw 42, the straw middle section 421 and the straw upper section 422 are preferably silica gel straws. The bending and / or telescoping function of the straw middle section 421 is realized by the flexibility and elasticity of the material itself, or by the structure, such as a bellows / accordion structure, or on the basis of flexibility, the straw 42 or the straw upper section 422 can slide relative to the cover body, in short, the above-mentioned functions can be realized Figure 4 Based on the prior art, various implementation manners can be conceived to achieve the effects shown in the embodiments, and the utility model is not limited to the solutions shown in the embodiments.

[0027] Please also refer to Figure 2 In the preferred embodiment, the cup body 6 has three inner containers, i.e., a first inner container 61, a second inner container 62 and a third inner container 63, all of which are open at the top. In the illustrated embodiment, the three inner containers are uniformly distributed in the circumferential direction; of course, other structural types can also be designed. The lower cup cover 3 is provided with a straight drinking port 41 and two straws 42, the straight drinking port 41 corresponds to the first inner container 61, and the two straws 42 correspond to the second inner container 62 and the third inner container 63, respectively; the two straws 42 are connected to the respective straw upper sections 422 through the respective straw middle sections 421.

[0028] Preferably, the first inner container 61 is a hot drink inner container for containing hot drinks, so that when used, the hot drinks can be poured into other cups through the straight drinking port 41, avoiding the problem of easy scalding of the mouth when using the straw to suck hot drinks. Further optionally, one of the second inner container 62 and the third inner container 63 is a cold drink inner container for containing cold drinks, and the other is a normal temperature inner container for containing normal temperature drinks, so that the three-temperature drink insulation cup can contain three kinds of temperature drinks at the same time.

[0029] It is conceivable that in other embodiments, the cup body 6 has only two inner containers, which can be understood as replacing the second inner container 62 and the third inner container 63 with one inner container based on the foregoing embodiment, and the straw can be selected as one, or still have two or more straws for multiple people to drink. Similarly, in still other embodiments, the cup body 6 has four or more inner containers, and more straws can be selected, and more layers of cup covers can also be selected.

[0030] More specifically, the vacuum cup of the present application preferably adopts a vacuum vacuum cup type, that is, each inner container and the cup body 6 has a vacuum layer. For example, the inner layer of the cup body adopts a 304 stainless steel vacuum design to realize the independent temperature of the three inner containers, and the 304 stainless steel has good corrosion resistance, low thermal conductivity and other characteristics, which can effectively reduce heat transfer. The existence of the vacuum layer further reduces the heat exchange between the inner container and the outside environment, thereby ensuring that the drinks in each inner container can maintain their initial temperature for a long time. Such a vacuum vacuum cup type is prior art, and the design of double inner container or three inner containers or more inner containers can be realized, so it is not described in detail. It is conceivable that in other embodiments, a non-vacuum vacuum cup type can also be used.

[0031] In the illustrated embodiment, the cover is designed as a three-layer structure, and all adopts a flip type with lock, not only makes the cup cover open and close operation is convenient, and guarantees the sealing and stability between each layer of cup cover. Specifically, the upper cup cover 1 and the middle cup cover 2 are rotatably connected on one side by the first rotating part 21 (for example, the pivot connection is formed by the rotating shaft), and the first clasp assembly 22 (for example, a spring buckle) is provided on the side opposite to the first rotating part 21 to realize the opening and closing between the upper cup cover 1 and the middle cup cover 2, and to ensure that the two can be tightly covered and fixed. Similarly, the middle cup cover 2 and the lower cup cover 3 are rotatably connected on one side by the second rotating part 31 (for example, the pivot connection is formed by the rotating shaft), and the second clasp assembly 32 (for example, a spring buckle) is provided on the side opposite to the second rotating part 31 to realize the opening and closing between the middle cup cover 2 and the lower cup cover 3, and to ensure that the two can be tightly covered and fixed. In addition, the first rotating part 21 and the second rotating part 31 have a spring, a limiting structure and the like, so that in the state that the clasp assembly is not connected, it can be automatically opened and kept in the cup cover open state for use.

[0032] More specifically, for example, the first clasp assembly 22 includes a first lock block 221 located at the bottom of the upper cup cover 1 and a first lock hole located at the middle cup cover 2; in the state that the upper cup cover 1 and the middle cup cover 2 are covered, the first lock block 221 is inserted into the first lock hole and locked; the middle cup cover 2 is provided with a first lock button 222 for pressing to control the unlocking and releasing of the first lock block 221, and the first lock button 222 is connected with a first elastic member 223 (for example, a spring) for elastic reset. The second clasp assembly 32 can adopt the same or similar structure, that is, the second clasp assembly 32 includes a second lock block 321 located at the bottom of the middle cup cover 2 and a second lock hole located at the lower cup cover 3; in the state that the middle cup cover 2 and the lower cup cover 3 are covered, the second lock block 321 is inserted into the second lock hole and locked; the lower cup cover 3 is provided with a second lock button 322 for pressing to control the unlocking and releasing of the second lock block 321, and the second lock button 322 is connected with a second elastic member 323 (for example, a spring) for elastic reset.

[0033] The structure of the above-mentioned button type to achieve the engagement and release of the lock is the prior art. For example, the upper end of the lock block has a protruding block towards the front and the lock block can have a certain deflection due to elasticity, so that the lock block can enter the lower lock hole when closing, and the side wall of the lock hole is formed with a step at the corresponding position of the block, so that after the lock block completely enters the lock hole, the block will naturally enter the lower step due to the elasticity. Thus, the lock block and the lock hole are fixed by the step and the block, and when unlocking, the lock button is pushed backward to push the block out of the step range.

[0034] It can be understood that there are many structures that can achieve similar cup cover opening and closing functions, and the present application is not limited to the above-mentioned specific way. In other feasible embodiments, the cup cover can be in the form of a screw cap, for example, or in the form of a press cover fixed by a detachable buckle structure, without conflicting with other structures. Further preferably, the straight drinking port 41 is located near the edge of the lower cup cover 3, and the first rotating part 21 and the second rotating part 31 are located away from the straight drinking port 41, so as to facilitate the use or pouring of the beverage through the straight drinking port 41 when using the flip cover.

[0035] Please refer to Figure 1 , Figure 2 In the preferred embodiment, the sealing structure is specially designed to cooperate with the lower cup cover 3 to achieve the sealing function of the cup body. Specifically, the sealing structure includes a sealing member 7, and the lower cup cover 3 is connected to the cup body 6 through a bottom cap 8. The bottom cap 8 is through from top to bottom, and the sealing member 7 is located in the bottom cap 8. The sealing member 7 has a through channel (such as a through hole or a tubular structure) corresponding to each inner container from top to bottom. The sealing member 7 is preferably a silica gel structure; for easy understanding, the sealing member 7 can be regarded as or replaced by a plurality of sealing rings / sealing sleeves corresponding to each inner container. The cup body 6 is provided with an external thread at the cup opening, and the bottom cap 8 is provided with an internal thread. The bottom cap 8 is threadedly connected to the cup body 6 in a matching manner. By rotating the bottom cap 8, the cover body can be tightly screwed on the cup body, thereby achieving good sealing effect and effectively preventing beverage leakage.

[0036] More specifically, for example, one of the outer side of the sealing member 7 and the inner wall of the bottom layer screw cover 8 has an annular protrusion, and the other has an annular groove. In the illustrated embodiment, the sealing member 7 has the annular protrusion, i.e., a flange. The annular protrusion and the annular groove are matched to form a rotatable snap connection between the sealing member 7 and the bottom layer screw cover 8, i.e., the sealing member 7 and the bottom layer screw cover 8 can rotate relative to each other, so that only the bottom layer screw cover 8 can be rotated without rotating the sealing member 7, which can be suitable for the case where the inner container and the cup body 6 are fixed. In the state where the bottom layer screw cover 8 is screwed with the cup body 6, the sealing member 7 is clamped between the bottom layer screw cover 8 and the cup body 6 to form a tight seal.

[0037] Alternatively, the sealing member 7 and the bottom layer screw cover 8 are always in tight fit, so that the relative rotation of the two can be realized by overcoming the static friction through force, and the sealing member and the bottom layer screw cover 8 are sealed in the natural state. Alternatively, the sealing is only in the screwed state, for example, see Figure 1 The upper end of the cup mouth of the cup body 6 is located in the bottom layer screw cover 8, and the bottom layer screw cover 8 has an inwardly extending edge above, so that the cup body 6 and the bottom layer screw cover 8 together form the aforementioned annular groove, and the thickness of the annular groove will gradually decrease as the bottom layer screw cover 8 is screwed, so that the annular protrusion on the outer side of the sealing member 7 is pressed and sealed, and the sealing member 7 is not in a clamped state during the process of unscrewing the bottom layer screw cover 8, which is easier to operate and also more convenient for the disassembly and cleaning of the sealing member 7.

[0038] The lower layer cup cover 3 and the bottom layer screw cover 8 are fixedly connected or detachably connected. For the case where the lower layer cup cover 3 and the bottom layer screw cover 8 are fixedly connected, in other words, the lower layer cup cover 3 has a lower portion with a thread. Optionally, the inner container and the cup body 6 are arranged to be rotatable, for example, the non-rotatable solution is to form the outer wall of the vacuum layer directly through the cup body 6, and the rotatable solution is to non-fixedly set the cup body 6 outside the outer wall of the vacuum layer, so that when the bottom layer screw cover 8 is rotated, the bottom layer screw cover 8 and the cup body 6 are relatively rotated to be screwed or unscrewed, and the bottom layer screw cover 8 and the inner container are simultaneously rotated, so that the straw 42 inserted into the inner container will not affect the rotation. In some embodiments, the lower layer cup cover 3 is directly connected with the cup body 6 by pressing, buckling or other means, and there is no process of rotation, and the straw will not affect the closing and the process of assembling / dismantling the vacuum cup combination. For the case where the lower layer cup cover 3 and the bottom layer screw cover 8 are detachably connected, the inner container and the cup body 6 can be optionally non-rotatable, and the lower layer cup cover 3 and the bottom layer screw cover 8 are connected by pressing, buckling or other means, and there is no process of rotation. Alternatively, for example, the lower layer cup cover 3 and the bottom layer screw cover 8 are rotatable but not detachable, so that only the bottom layer screw cover 8 is rotated when screwed.

[0039] Please refer to Figure 1 , Figure 4, preferably, the straight drinking sealing part 51 is a sealing plug located at the bottom of the middle cup cover 2 and protruding downward, the position and size of the sealing plug correspond to the straight drinking port 41, so that the straight drinking port 41 can be closed when the middle cup cover 2 is closed. In addition, in the illustrated embodiment, the straight drinking port 41 has a certain height, which is convenient for guiding the beverage to flow out and also convenient for sealing by the sealing plug. It is conceivable that in other embodiments, the straight drinking sealing part 51 can also be selected as a flip cover arranged on the middle cup cover 2 or the straight drinking port 41, so that the straight drinking sealing part 51 also needs to be manually opened after the middle cup cover 2 is opened. When this mode is adopted, the straight drinking port 41 and the corresponding inner container can be selected as two or more, because it can be controlled to open only one of them, and the rest are closed, and only the opened straight drinking port 41 can pour out the beverage when the beverage is poured.

[0040] Please refer to Figure 1 、 Figure 2 , preferably, the straw sealing part 52 is a pressing plate or a baffle located at the bottom of the upper cup cover 1 and protruding downward. In the illustrated embodiment, the straw sealing part 52 is a pressing plate located at the bottom of the upper cup cover 1 and protruding downward, the upper segment 422 of the straw protrudes upward and forward above the middle cup cover 2 by a distance for convenient use, the pressing plate can press and close the upper segment 422 of the straw when the upper cup cover 1 is closed, and the upper segment 422 of the straw restores the open state due to the elasticity after the upper cup cover 1 is opened. In other embodiments, the straw sealing part 52 is a baffle located at the bottom of the upper cup cover 1 and protruding downward, which is used to block and seal the end of the upper segment 422 of the straw in the closed state of the upper cup cover 1. It is conceivable that in still other embodiments, the straw sealing part 52 can also be selected as a straw cap / straw plug arranged on the upper cup cover 1 or the middle cup cover 2 or the upper segment 422 of the straw, which needs to be manually opened after the upper cup cover 1 is opened.

[0041] To further highlight the beneficial technical effects of the present application, a typical application mode is given below. Pressing the lower lock button can open the upper part of the lower cup cover, and the lower cup cover is specially designed for hot beverage straight drinking mode, and the corresponding inner container is used to store hot water, which can be directly poured out when drinking to avoid the problem of burning mouth that may occur when using a straw. In addition, two telescopic middle segment silica gel straws are arranged behind the hot beverage port of the cup cover, and the two straws are connected with the lower segments of the silica gel straws in the other two inner containers of the middle cup cover and the cup body, respectively, to form a complete straw passage. When the upper lock button is pressed, the upper cup cover, i.e. the dustproof cup cover, can be opened, and through the two silica gel straws on the middle cup cover, the user can conveniently drink different beverages in the other two inner containers.

[0042] Please refer to Figure 5, preferably, the three-layer flip cover and two-button structure is used to ensure more functions, easy operation and convenient selection; if the number of layers, buttons, inner containers or straws is too much, it is easy to cause confusion. Alternatively, the upper cup cover can be replaced by a screw cap and used as a cup. Preferably, as shown in Figure 2 Each part shown in the above embodiment can be detachable (the first and second rotating parts and the first and second buckle assemblies do not have to be detachable) to facilitate disassembly and cleaning of the vacuum cup.

[0043] In summary, the cover of the multi-inner-container multifunctional vacuum cup has a multi-layer structure, when the upper cup cover is opened, one or more upper sections of the straws are exposed, so that the corresponding inner container can be sucked through the straw; when the middle cup cover is opened, the direct drinking opening is exposed, so that the corresponding inner container can be directly drunk or poured out, which is particularly important for hot drinks or drinks containing solid food that are not convenient to use a straw; at the same time, the deformable middle section of the straw can ensure that the corresponding part of the straw is closed when the direct drinking opening is used, and the drink in the corresponding inner container will not leak out due to the inclination of the cup body; the unique structure of the vacuum cup can meet the needs of users to drink hot, cold and room temperature drinks in one cup, and ensure that different temperatures and different types of drinks do not affect each other in the same cup, and the liquids will not mix.

[0044] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not to limit them; obviously, the described embodiments are part of the embodiments of the present application, but not all.
