Description

Technical Field

[0001] The utility model relates to a straw cup, in particular to an elastic straw cup and a cup cover assembly thereof. Background Art

[0002] Straw cups are suitable for infants and young children because they are easy for users to absorb water and are not prone to leakage. The straw part of some straw cups can be disassembled for local cleaning and disinfection, ensuring the hygiene of drinking. When disassembling the straw part of the straw cup, the straw is firmly installed on the cup cover, which will also cause the hygiene of the cup cover to be contaminated during the disassembly process. Correspondingly, because the straw part is firmly installed on the cup cover, it will also cause the suction nozzle of the straw to be drunk by the user again. Covering the cup cover increases the contact area between the cup cover and the suction nozzle of the straw, thereby further contaminating the hygiene of the cup cover. In addition, when purchasing a straw cup, the sealing of the straw cup is a key factor for users to consider. The suction nozzle part of the straw cup on the market is mostly pressed by the cup cover to prevent the liquid in the cup body from leaking out. This method, on the one hand, causes the suction nozzle to contaminate the cup cover after use, and on the other hand, the closed cup cover will flatten the suction nozzle. The elastic material of the suction nozzle will also make the closed cup cover not fixed firmly and the flattened suction nozzle will bounce open, which is very likely to cause the cup to leak.

[0032] Refer to the attached drawings of the specification of this utility model Figures 1 to 6 In the following description, an elastic straw cup according to a preferred embodiment of the present invention will be disclosed and explained, wherein the elastic straw cup includes a cup body 10 and a cup cover assembly 20 detachably mounted on the cup body 10 .

[0033] The cup body 10 has a cup body space 11 and a cup body opening 12 connected to the cup body space 11, and the cup cover assembly 20 is used to close the cup body opening 12 of the cup body 10, wherein after the cup cover assembly 20 is removed from the cup body 10, the cup body opening 12 of the cup body 10 is exposed to allow the user to add water to the cup body space 11 through the cup body opening 12 of the cup body 10, wherein after the cup cover assembly 20 is installed on the cup body 10, the cup cover assembly 20 closes the cup body opening 12 of the cup body 10 to allow the user to conveniently carry the elastic straw cup.

[0034] The specific structure of the cup body 10 is not limited in the elastic straw cup of the present invention. Figures 1 to 6 In the specific example of the elastic straw cup shown, the cup body 10 is a double-layer structure, which includes a cup body inner layer 13 and a cup body outer layer 14 which is sleeved on the outside of the cup body inner layer 13. The cup body inner layer 13 defines the cup body space 11 and the cup body opening 12 of the cup body 10, and the cup body outer layer 14 forms the appearance of the cup body 10. The material of the cup body inner layer 13 can be stainless steel, for example, 304 stainless steel can be used to make the cup body inner layer 13, and the material of the cup body outer layer 14 can be plastic, for example, the cup body outer layer 14 can be formed by plastic particles through an injection molding process. After the cup body inner layer 13 and the cup body outer layer 14 are made separately, the cup body inner layer 13 can be embedded in the cup body outer layer 14 to allow the cup body outer layer 14 to be sleeved on the cup body inner layer 13. Optionally, in other examples of the elastic straw cup of the present invention, the inner layer 13 of the cup body and the outer layer 14 of the cup body can both be made of stainless steel, so that the space between the inner layer 13 of the cup body and the outer layer 14 of the cup body can form a vacuum environment, so that the cup body 10 has a heat preservation function, that is, the cup body 10 can be a heat-insulating cup body.

[0035] Preferably, the cup body 10 further includes at least one handle 15, and the handle 15 is disposed on the cup body outer layer 14. For example, the handle 15 can be integrally injection molded with the cup body outer layer 14. More preferably, the cup body 10 includes two handles 15, and the two handles 15 are symmetrically disposed on opposite sides of the cup body outer layer 14.

[0036] Continue to refer to the attached Figures 1 to 6The cup cover assembly 20 includes a cup cover 21, a straw 22 and an elastic element 23. The cup cover 21 includes a main cover body 211 and a flip cover body 212. The main cover body 211 further includes a cover element 2111 and an extension ring 2112. The cover element 2111 and the extension ring 2112 are integrally formed. The cover element 2111 surrounds the middle of the extension ring 2112. The extension ring 2112 has an annular space 21121 and an annular opening 21122 and a straw hole 21123 respectively connected to the annular space 21121. The flip cover body 212 is flipably connected to the cover element 2111, and the flip cover body 212 can be switched between a closed state and an open state by flipping. The straw 22 includes a tube body 221 and a tube body 223 respectively arranged on the tube body 2 The tube body 221 has an upper boss 222 and a lower boss 223 at different height positions of the tube body 221, the tube body 221 is mounted on the straw hole 21123 of the extension ring 2112 so as to be movably mounted up and down, the upper boss 222 and the lower boss 223 are respectively located above and below the straw hole 21123 of the extension ring 2112, and the outer diameter of the upper boss 222 and the outer diameter of the lower boss 223 are both larger than the inner diameter of the straw hole 21123 of the extension ring 2112, wherein the elastic element 23 is sleeved on the tube body 221, and the top of the elastic element 23 abuts against the upper boss 222 of the straw 22, and the bottom of the elastic element 23 abuts against the bottom of the extension ring 2112.

[0037] When the flip cover 212 switches from the closed state to the open state, the elastic element 23 drives the straw 22 to move upward and allows the top of the tube body 221 to expose the extension ring 2112, so that the user can drink the water contained in the cup body 10 through the straw 22. When the flip cover 212 switches from the open state to the closed state, the flip cover 212 presses down the top of the tube body 221 to hide the straw 22, and at this time, the extension ring 2112 and the upper boss 222 of the straw 22 compress the elastic element 23, causing the elastic element 23 to deform and accumulate elastic potential energy.

[0038] That is to say, in the attached Figures 1 to 6In this specific example of the elastic straw cup of the utility model shown, when the flip body 212 is flipped to switch the flip body 212 from the closed state to the open state, the elastic element 23 causes the straw 22 to automatically move upward and allows the top of the tube body 221 to expose the extension ring 2112 of the main cover body 211, thereby facilitating the user to drink the water contained in the cup body 10 through the straw 22. When the flip body 212 is flipped to switch the flip body 212 from the open state to the closed state, the flip body 212 presses down the straw 22 and allows the tube body 221 to be hidden. In the above processes, the user does not need to touch the straw 22 with his hands, which is conducive to ensuring the hygiene of the straw 22.

[0039] It can be understood that when the flip body 212 is in the closed state, the flip body 212 drives the straw 22 to be pressed downward, so that the upper boss 222 of the straw 22 and the bottom of the extension ring 2112 compress the elastic element 23. Therefore, the elastic element 23 has a tendency to move the straw 22 upward and allows the top of the tube body 221 to be close to the flip body 212, so as to prevent the water contained in the cup body 10 from leaking through the fitting position of the flip body 212 and the tube body 221.

[0040] In the attached Figures 1 to 6In the specific example of the elastic straw cup of the utility model shown, the straw 22 can be an integrated structure made of silicone material, so that the straw 22 can be deformed, especially the lower boss 223 of the straw 22 can be deformed, so as to facilitate the installation of the straw 22 on the cup cover 21. The specific process of installing the straw 22 on the cup cover 21 is as follows: first, the elastic element 23 is mounted on the tube body 221 at a position between the upper boss 222 and the lower boss 223. At this time, the top of the elastic element 23 abuts against the upper boss 222 of the straw 22, and the bottom of the elastic element 23 abuts against the lower boss 223 of the straw 22. Secondly, the straw 22 is installed in a manner that allows the bottom of the tube body 221 to be inserted into the straw hole 21123 of the extension ring 2112. When the lower boss 223 of the straw 22 moves to above the straw hole 21123 in the annular space 21121 of the extension ring 2112, as the straw 22 continues to move downward, the The lower boss 223 of the straw 22 is deformed upward to reduce the size of the lower boss 223 in the circumferential direction, and the deformed lower boss 223 can pass through the straw hole 21123 of the extension ring 2112. After the lower boss 223 passes through the straw hole 21123 of the extension ring 2112, the lower boss 223 automatically restores to its initial state, and at this time, on the one hand, since the outer diameter of the lower boss 223 of the straw 22 is larger than the inner diameter of the straw hole 21123 of the extension ring 2112, the lower boss 223 after restoring to the initial state can prevent the straw 22 from automatically falling from the cup cover 21, and on the other hand, the bottom of the elastic element 23 abuts against the bottom of the extension ring 2112.

[0041] Preferably, the inner diameter of the annular space 21121 of the extension ring 2112 is larger than the inner diameter of the straw hole 21123 , so that the extension ring 2112 forms a resting platform 21124 at the edge of the straw hole 21123 , and the bottom of the elastic element 23 rests against the resting platform 21124 of the extension ring 2112 .

[0042] Reference Figure 6 When the flip cover 212 is in the open state, the extension ring 2112 blocks at least a portion of the upper boss 222 of the straw 22 from a side view, so that the elastic element 23 is prevented from being exposed and is visually invisible, which is beneficial to ensuring the aesthetics of the elastic straw cup.

[0043] Reference Figure 4 and Figure 6In this specific example of the elastic straw cup of the present invention, the cover element 2111 surrounds the middle of the extension ring 2112, so the top of the extension ring 2112 protrudes above the cover element 2111, and the bottom of the extension ring 2112 protrudes below the cover element 2111. After the straw 22 is removed from the cup cover 21, the user can directly drink the water contained in the cup body 10 through the extension ring 2112. In other words, the elastic straw cup of the present invention can be used as a direct drinking cup.

[0044] Continue to refer to the attached Figures 1 to 6 The flip cover body 212 includes a flip cover portion 2121 and a flexible sealing portion 2122 arranged on the flip cover portion 2121, and the flip cover portion 2121 is flipably mounted on the cover element 2111 of the main cover body 211, wherein when the flip cover body 212 is in the closed state, the sealing portion 2122 seals the tube body 221 of the straw 22 to improve the sealing performance of the elastic straw cup. Specifically, after the flip cover body 212 switches from the open state to the closed state, since the elastic element 23 has the tendency to move the straw 22 upward, the top of the tube body 221 can be close to the sealing portion 2122 of the flip cover body 212. At this time, the sealing portion 2122 and the top of the tube body 221 can be slightly deformed to prevent a gap from being generated between the sealing portion 2122 and the top of the tube body 221, so as to prevent water from leaking through the joint position of the tube body 221 and the sealing portion 2122, thereby improving the sealing performance of the elastic straw cup.

[0045] It is worth mentioning that the specific manner in which the sealing portion 2122 is disposed on the flap portion 2121 is not limited in the elastic straw cup of the present invention. For example, in this specific example of the elastic straw cup of the present invention, the sealing portion 2122 is integrally formed on the flap portion 2121 to set the sealing portion 2122 on the flap portion 2121. For example, a secondary encapsulation process can be used to integrally form the sealing portion 2122 on the flap portion 2121. In other specific examples of the elastic straw cup of the present invention, the flap portion 2121 and the sealing portion 2122 can be made separately, and then the sealing portion 2122 is installed on the flap portion 2121 to set the sealing portion 2122 on the flap portion 2121.

[0046] Continue to refer to the attached Figures 4 to 6The sealing portion 2122 of the flip cover 212 has a sealing ring 21221 extending downward. When the flip cover 212 is in the closed state, the sealing ring 21221 surrounds the top of the extension ring 2112 in a manner that the inner wall of the sealing ring 21221 is attached to the outer wall of the extension ring 2112 to wrap the top of the extension ring 2112. This can not only further improve the sealing performance of the elastic straw cup, but also the extension ring 2112 and the sealing ring 21221 cooperate with each other to enable the flip cover 212 to be reliably maintained in the closed state. In other words, by allowing the cover element 2111 to surround the middle of the extension ring 2112 so that the top of the extension ring 2112 protrudes above the cover element 2111, not only can the elastic straw cup be used as a direct drinking cup, but also the flip cover 212 can be reliably maintained in the closed state.

[0047] It can be understood that when the flip cover 212 is in the closed state, by allowing the sealing ring 21221 of the sealing portion 2122 to wrap the top of the extension ring 2112, even if the straw 22 is removed, the sealing portion 2122 can reliably seal the ring body opening 21122 of the extension ring 2112 to ensure the sealing of the elastic straw cup.

[0048] Further, see Attachment Figure 4 and Figure 6 The cover element 2111 has an insertion ring 21111 that extends downward and retracts inward. When the cup cover assembly 20 is installed on the cup body 10, the insertion ring 21111 of the cover element 2111 is allowed to be inserted into the cup body space 11 of the cup body 10 through the cup body opening 12 of the cup body 10, and the cover element 2111 rests on the edge of the cup body 10 for forming the cup body opening 12. Preferably, in order to ensure that the cup cover assembly 20 reliably closes the cup body opening 12 of the cup body 10, the cup cover assembly 20 may further include a sealing ring 24, and the sealing ring 24 is sleeved on the insertion ring 21111 of the cover element 2111. After the cup cover assembly 20 is installed on the cup body 10 and the insertion ring 21111 of the cover element 2111 is inserted into the cup body space 11 of the cup body 10 through the cup body opening 12 of the cup body 10, the insertion ring 21111 and the cup body 10 squeeze the sealing ring 24, causing the sealing ring 24 to be slightly deformed, so that the sealing ring 24 improves the effect of the cup cover assembly 20 in closing the cup body opening 12 of the cup body 10.

[0049] Furthermore, the main cover body 211 includes a lifting portion 2113, and the lifting portion 2113 protrudes from the edge of the cover element 2111 to facilitate the user to remove the cup cover assembly 20 from the cup body 10. Preferably, the lifting portion 2113 and the cover element 2111 are an integrated structure.

[0050] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
