Description

Technical Field

[0001] This application relates to the field of water cup technology, and more particularly to straw cups. Background Technology

[0002] A straw cup is a type of water cup that uses a built-in straw. Unlike regular water cups, a straw cup has a special hole on the top of the lid for inserting a straw. One end of the straw extends out of the lid, and the other end extends into the cup. When the cup contains a beverage, the user can drink from the end of the straw that is outside the cup. Since straw cups are usually sealed except for the straw opening, a pressure relief vent is needed to ensure smooth liquid flow during use. However, the pressure relief vent of straw cups is usually directly exposed, which makes it easy for liquid to overflow when the cup is tilted, and also allows external contaminants to enter the cup and contaminate the liquid.

[0003] To address the aforementioned issues, existing technologies have offered corresponding improvements. For example, Chinese patent application CN218651274U, published on March 21, 2023, discloses a straw cup. This cup includes a cup body, a lid, and a straw mounted on the lid. The lid also features a pressure-relief structure, comprising a sealing plug embedded in the lid and simultaneously fitted onto the straw. The sealing plug has a pressure-relief port communicating with the inside and outside of the cup body. A detachable sealing cap is attached to the lid, which simultaneously fits onto the straw to seal it and abuts against the sealing plug to close the pressure-relief port. The drawback of this solution is that after removing the sealing cap, the pressure-relief port becomes directly exposed. If the sealing cap is not reattached for an extended period after drinking, external contaminants can easily enter the cup body through the pressure-relief port. Utility Model Content

[0004] The purpose of this application is to solve the problem in the prior art that it is impossible to simultaneously ensure the sealing of the pressure relief port of a straw cup in the non-use state and its obstruction in the use state. Therefore, this application provides a straw cup that achieves both sealing of the pressure relief port in the non-use state and obstruction in the use state through the cooperation of a cover, a sealing member, a first elastic member, and a straw cap.

[0005] This application provides a straw cup, including a cup body and a cup lid, wherein a straw is inserted into the cup lid, and the cup lid is provided with a pressure relief port communicating with the inside and outside of the cup body;

[0006] The cup lid is also provided with a cover, and the straw passes through the cover;

[0007] A sealing element and a first elastic element are provided between the cover and the cup lid;

[0008] A straw cap is detachably connected to the straw. The straw cap can be sleeved on the straw to close it and at the same time abut against the sealing member, thereby driving the sealing member to close the pressure relief port.

[0009] The first elastic element applies a thrust away from the pressure relief port to the sealing element. When the straw cap moves away from the sealing element, the first elastic element can push the sealing element away from the pressure relief port. Furthermore, the sealing element and the cover cooperate to block the pressure relief port. There is a gap between the edge of the cover and the surface of the cup cap and it communicates with the outside.

[0010] By employing the above technical solution, the cooperation of the cover, sealing component, first elastic component, and straw cap achieves both sealing of the pressure relief port of the straw cup in the non-use state and shielding in the use state. In the non-use state, i.e., when not drinking through a straw, the pressure relief port is sealed by the straw cap, which in turn drives the sealing component to prevent liquid from overflowing through the pressure relief port, ensuring the straw cup's airtightness. In the use state, i.e., when drinking through a straw, the straw cap is removed, and the sealing component, driven by the first elastic component, moves away from the pressure relief port, opening it. The pressure relief port then connects the inside and outside of the cup through the gap between the edge of the cover and the cup cap, achieving the pressure relief function. Simultaneously, the pressure relief port is shielded by the sealing component and the cover, reducing the probability of external contamination entering the cup through the pressure relief port.

[0011] In some embodiments, the sealing member includes a first limiting portion that can abut against the cover to prevent the sealing member from continuing to move away from the pressure relief port under the push of the first elastic member.

[0012] By adopting the above technical solution, the first limiting part cooperates with the cover to limit the sealing part, so that the sealing part can remain between the cover and the cup lid after it is separated from the straw cap.

[0013] In some embodiments, the end of the sealing member away from the pressure relief port may extend out of the cover under the push of the first elastic member, and the straw cap may abut against the end of the sealing member and drive the sealing member to close the pressure relief port.

[0014] In some embodiments, the pressure relief port is located close to the straw, and the sealing element is sleeved on the straw.

[0015] In some embodiments, the limiting surface between the first limiting portion and the cover is an inclined surface.

[0016] In some embodiments, the cup lid is provided with a water inlet communicating with the inside and outside of the cup body, the cover is provided with a sealing plug adapted to the water inlet, and the cover is hinged to one side of the cup lid and detachably snapped to the other side.

[0017] By adopting the above technical solution, water can be poured into the cup without separating the cup lid and the cup body through hinge and snap-fit ​​sealing plug, thus improving the convenience of use.

[0018] In some embodiments, the cover is provided with a claw, and the cup lid is slidably provided with a groove that engages with the claw along a first direction;

[0019] The card slot is located at both ends in the first direction and abuts against the second elastic member and the operating member respectively. The operating member can push the card slot to slide along the first direction and switch it between a snap-in position and a disengagement position. In the snap-in position, the card slot can snap into the card claw. In the disengagement position, the card slot is disengaged from the card claw.

[0020] By adopting the above technical solution, the second elastic element and the operating element cooperate to enable the slot to slide along the first direction and engage or disengage with the claw, thereby improving the convenience of detachable engagement of the cover and the cup lid.

[0021] In some embodiments, a limiting element is provided on the cup lid;

[0022] The operating element has a first state and a second state;

[0023] In the first state, the limiting member abuts against the operating member to prevent the operating member or the second elastic member from pushing the slot to slide, and the slot is located in the engaging position;

[0024] In the second state, the limiting member is separated from the operating member, and the operating member can push the slot to slide along the first direction, thereby switching between the engaging position and the disengaged position.

[0025] By adopting the above technical solution, the operating component can lock the engagement state of the claw and the slot in the first state, and can unlock the engagement state of both in the second state, thereby improving the reliability of the engagement between the cover and the cup lid.

[0026] In some embodiments, a sliding channel is provided inside the cup lid, and the extending direction of the sliding channel intersects with the first direction;

[0027] The operating component is slidably disposed within the sliding channel and can slide along the extension direction of the sliding channel, thereby switching between the first state and the second state.

[0028] By adopting the above technical solution, when the cover and cup lid are unlocked and engaged, the operating component needs to slide to one side first and then press forward. That is, the operating component needs to move in two different directions to achieve unlocking and engagement, which further improves the reliability of the engagement between the cover and cup lid.

[0029] In some embodiments, the straw includes a first segment and a second segment, the first segment being connected to the cover and the second segment being connected to the cup lid, and when the cover and the cup lid are engaged, the first segment and the second segment are in close communication.

[0030] In some embodiments, a filter element is detachably connected to the end of the second pipe segment.

[0031] In some embodiments, the cup body includes a nestable first cup body and a second cup body, and the first cup body and the second cup body are nested together and connected by a first connector, and the cup lid can be threadedly connected to both the first cup body and the second cup body.

[0032] In some embodiments, the cup body is provided with a handle, and the straw cap is detachably connected to the end of the handle.

[0033] Other features and corresponding beneficial effects of this application will be described in the latter part of the specification, and it should be understood that at least some of the beneficial effects will become obvious from the description in this application.

[0052] Please see Figure 1-2 , Figure 1 This is a schematic diagram of the structure of this application; Figure 2 This is a cross-sectional view of this application.

[0053] This application provides a straw cup, including a cup body 10 and a cup lid 20. A straw 30 is inserted into the cup lid 20, and a pressure relief port 21 is provided on the cup lid 20 that communicates with the inside and outside of the cup body 10.

[0054] In one embodiment, the end of the straw 30 is detachably connected to a filter element 33, meaning that tea leaves or other infusions can be placed directly into the cup body 10 and filtered through the end of the straw 30 located inside the cup body 10. This ensures that there is more space for the infusions compared to a tea caddy, which is especially convenient for infusing larger-volume infusions such as lemon slices. At the same time, the liquid can still be filtered through the filter element 33 for easy drinking.

[0055] Preferably, the filter element 33 is spherical, thus having a larger filtration area, preventing the filter pores of the filter element 33 from being completely blocked by infused substances such as tea leaves, which would affect water absorption.

[0056] In one embodiment, the cup body 10 includes a nestable first cup body 11 and a second cup body 12. The first cup body 11 and the second cup body 12 are nested together and connected by a first connector 14 to form a whole, preventing them from separating during use. Simultaneously, they can also be used separately, thus providing the user with two water cups and improving the practicality of this straw cup. The first connector 14 is preferably a silicone ring, which is fitted onto the seam between the first cup body 11 and the second cup body 12, ensuring a tight connection when the first cup body 11 and the second cup body 12 are nested together.

[0057] Preferably, the lid 20 can be threadedly connected to both the first cup body 11 and the second cup body 12, further improving the practicality of this straw cup.

[0058] In one embodiment, a straw cap 70 is detachably attached to the straw 30.

[0059] Preferably, the cup body 10 is provided with a handle 13, and the straw cap 70 is detachably connected to the end of the handle 13, such as by threaded connection or magnetic attraction, so that the straw cap 70 can be assembled with the handle 13 when it is removed, thus avoiding omission.

[0060] Please refer to the above. Figure 3 , Figure 3 This is a partial cross-sectional perspective view of the three-dimensional structure of this application, with the pressure relief port 21 closed.

[0061] In one embodiment, the cup lid 20 is further provided with a cover 40, and the straw 30 passes through the cover 40.

[0062] A sealing element 50 and a first elastic element 60 are provided between the cover 40 and the cup lid 20.

[0063] The straw cap 70 can be fitted onto the straw 30 to seal it, and at the same time abut against the sealing member 50, causing the sealing member 50 to close the pressure relief port 21.

[0064] The first elastic element 60 applies a pushing force to the sealing element 50 away from the pressure relief port 21. When the straw cap 70 moves away from the sealing element 50, the first elastic element 60 can push the sealing element 50 away from the pressure relief port 21. Furthermore, the sealing element 50 and the cover 40 cooperate to block the pressure relief port 21. There is a gap between the edge of the cover 40 and the surface of the cup cap 20, which communicates with the outside. The first elastic element 60 is preferably a spring.

[0065] The above method ensures that when the straw cup is not in use, i.e. when drinking water without using the straw 30, the pressure relief port 21 is sealed by the straw cap 70 moving the sealing member 50 downward, preventing liquid from overflowing from the cup body 10 through the pressure relief port 21 and ensuring the straw cup's airtightness. When in use, i.e. when drinking water through the straw 30, the straw cap 70 is removed, and the sealing member 50 moves away from the pressure relief port 21 under the action of the first elastic member 60. The pressure relief port 21 opens and connects the inside and outside of the cup body 10 through the gap between the edge of the cover 40 and the cup cap 20, realizing the pressure relief function. At the same time, the pressure relief port 21 is blocked by the sealing member 50 and the cover 40 and is not directly exposed, reducing the probability of external contamination entering the cup body 10 through the pressure relief port 21.

[0066] In one specific embodiment, the straw cap 70 is threadedly connected to the straw 30, which improves the reliability and stability of the straw cap 70 in maintaining its closed state of the straw 30 and abutting the sealing member 50, and is also convenient to operate.

[0067] A silicone part is preferably provided at the pressure relief port 21 to achieve a sealing effect with the sealing part 50.

[0068] In one embodiment, the sealing member 50 includes a first limiting part 51, which can abut against the cover 40 to prevent the sealing member 50 from continuing to move away from the pressure relief port 21 under the push of the first elastic member 60. That is, through the cooperation of the first limiting part 51 and the cover 40, the sealing member 50 is limited, so that at least the main body of the sealing member 50 can remain between the cover 40 and the cup lid 20 after it is separated from the straw cap 70. This makes it easier for the straw cap 70 to abut against the sealing member 50 again and close the pressure relief port 21.

[0069] In one specific embodiment, the limiting surfaces of the first limiting part 51 and the cover 40 are inclined surfaces, thereby increasing the contact area between the two and extending the service life of the first limiting part 51.

[0070] In one specific embodiment, the end of the sealing member 50 facing away from the pressure relief port 21 can extend out of the cover 40 under the push of the first elastic member 60. The straw cap 70 can abut against the end of the sealing member 50 and drive the sealing member 50 to close the pressure relief port 21. Thus, by setting the sealing member 50 of appropriate length, the straw cap 70 can only contact the end of the sealing member 50 without extending into the cover 40 to drive the sealing member 50 to close the pressure relief port 21. This avoids the straw cap 70, which is easily contaminated, from contaminating the inside of the cover 40 and thus the pressure relief port 21. In other words, it further prevents external pollutants from entering the cup body 10 through the pressure relief port 21.

[0071] In one specific embodiment, the pressure relief port 21 is located close to the straw 30, and the sealing member 50 is sleeved on the straw 30.

[0072] Please refer to the above. Figure 4-5 , Figure 4 This is a cross-sectional perspective view of another part of the structure of this application; Figure 5 This is a cross-sectional three-dimensional structural schematic diagram of another part of this application.

[0073] In one embodiment, the cup lid 20 is provided with a water inlet 22 that communicates with the inside and outside of the cup body 10, and the cover 40 is provided with a sealing plug 43 that matches the water inlet 22. The cover 40 is hinged to the cup lid 20 on one side and can be detachably snapped on the other side, so that water can be poured into the cup by opening the cover 40 without separating the cup lid 20 and the cup body 10, which improves the convenience of use.

[0074] In one embodiment, the cover 40 is provided with a claw 44, and the cup lid 20 is provided with a groove 23 that cooperates with the claw 44 in a first direction.

[0075] The slot 23 is located at both ends in the first direction, where it abuts against the second elastic member 80 and the operating member 90 respectively. The operating member 90 can push the slot 23 to slide along the first direction, allowing it to switch between the engaged and disengaged positions, thus improving the convenience of disassembling and engaging the cover 40 and the cup lid 20. The second elastic member 80 is preferably a spring.

[0076] It is understandable that when in the engaging position, the slot 23 can engage with the claw 44, and when in the disengaged position, the slot 23 and the claw 44 are disengaged.

[0077] In one embodiment, a limiting member 24 is provided on the cup lid 20.

[0078] The operating element 90 has a first state and a second state.

[0079] In the first state, the limiting member 24 abuts against the operating member 90 to prevent the operating member 90 or the second elastic member 80 from pushing the slot 23 to slide, and the slot 23 is in the engaging position. Thus, when the claw 44 engages with the slot 23, the operating member 90 can lock the engaging state of the claw 44 and the slot 23 in the first state.

[0080] In the second state, the limiting member 24 is separated from the operating member 90, and the operating member 90 can push the card slot 23 to slide along the first direction, and switch between the engaging position and the disengaged position. That is, the engaging state of the two can only be unlocked in the second state.

[0081] This method improves the reliability of the engagement between the cover 40 and the cup lid 20 by switching between the first and second states using the operating component 90.

[0082] Preferably, the end of the operating member 90 corresponding to the limiting member 24 is provided with an abutment part 91. In the first state and the second state, the position of the abutment part 91 is different, so as to realize that the abutment part 91 of the limiting member 24 abuts or separates from the operating member 90.

[0083] In one embodiment, a sliding channel 25 is provided inside the cup lid 20, and the extending direction of the sliding channel 25 intersects with the first direction. The operating member 90 is slidably disposed inside the sliding channel 25 and can slide along the extending direction of the sliding channel 25, so that when switching between the first state and the second state, that is, when the cover 40 and the cup lid 20 are unlocked and engaged, the operating member 90 needs to slide to one side first and then press forward. In other words, the operating member 90 needs to move in two different directions to achieve unlocking and engagement, which further improves the reliability of the engagement between the cover 40 and the cup lid 20.

[0084] The cup lid 20 is usually round. In this case, the sliding channel 25 can be set to be arc-shaped. The smaller the angle between the first direction and the bisector of the arc, the better. This will make the difference in movement between the two directions of the operating part 90 greater and avoid misoperation.

[0085] It is understood that the operating member 90 includes a second limiting part 92, which, along with the second elastic member 80, keeps the operating member 90 always connected to the cup lid 20.

[0086] In one embodiment, a second connector 93 is detachably connected to the operating member 90. The volume of the second connector 93 may be larger than that of the operating member 90, thereby facilitating user operation. Furthermore, the user can enhance the user experience by replacing different second connectors 93. Preferably, the second connector 93 is an elastic member and is sleeved with the operating member 90.

[0087] In one embodiment, the straw 30 includes a first tube segment 31 and a second tube segment 32. The first tube segment 31 is connected to the cover 40, and the second tube segment 32 is connected to the cup lid 20. When the cover 40 and the cup lid 20 are engaged, the first tube segment 31 and the second tube segment 32 are in close communication, thereby enabling drinking water.

[0088] At this point, the filter element 33 can be detachably connected to the end of the second pipe section 32.

[0089] To improve the reliability of the connection between the first tube segment 31 and the second tube segment 32, the first tube segment 31 is preferably a rigid tube with a sealing ring at the connection end. At this time, a flexible straw nozzle 34, preferably a silicone straw nozzle, is preferably fitted onto the top of the first tube segment 31 to improve the user experience. The second tube segment 32 is a silicone straw to facilitate bending within the cup body 10. Furthermore, the second tube segment 32 and the silicone part at the vent 21 are integrally formed. Preferably, the second tube segment 32 is a two-piece sleeve for ease of forming and cleaning.

[0090] In one embodiment, the cover 40 includes a first split part 41 and a second split part 42 connected to each other. The first split part 41 covers the second split part 42, and the first split part 41 is provided with a claw 44, while the second split part 42 is provided with a sealing plug 43.

[0091] At this time, the sealing member 50 and the first elastic member 60 are disposed between the first split part 41 and the second split part 42, and the second split part 42 is provided with a through hole corresponding to the pressure relief port 21, so that the sealing member 50 can close the pressure relief port 21 through the through hole. This method allows the sealing member 50 and the first elastic member 60 to be integrated with the cover body 40 as one unit, which is convenient for use.

[0092] Preferably, the first pipe section 31 and the second split part 42 are integrally formed.

[0093] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
