Description

Technical Field

[0001] This utility model belongs to the field of paper cups, and in particular relates to a portable paper cup. Background Technology

[0002] With the rapid development of the fast-moving consumer goods (FMCG) beverage industry, paper cups have become an indispensable container product in daily life and business consumption due to their advantages such as portability, low cost, and disposable use, and are widely used for serving and carrying beverages such as coffee, milk tea, and hot drinks. To improve the portability of paper cups, existing technologies generally adopt a design scheme that incorporates a handle structure on the outer cup body. Among these, the handle structure formed by creating a tear or tear line on the side wall of the outer cup body and combining it with a bendable carrying strap is currently the most widely used technical form.

[0003] For example, a heat-resistant paper cup with application number 201821617643.0 includes a cup body and a cup lid. The cup body includes an inner cup body, an outer cup body, and a cup bottom. The cup bottom is fixedly fitted onto the inner cup body. The upper outer side of the inner cup body and the upper inner side of the outer cup body are fixedly bonded by adhesive. The outer cup body is provided with tear line one, tear line two, tear line three, and tear line four. A piece of paper between tear line one and tear line two extends to one end with an arc-shaped piece of paper whose diameter is slightly wider than the distance between tear line one and tear line two. The arc-shaped piece of paper is provided with a hole. A piece of paper between tear line three and tear line four extends to one end with an irregularly shaped piece of paper that matches and engages with the hole.

[0004] Because the carrying strap is connected to the cup's side wall via a tear-off structure, its connection location and structural design result in a lack of effective storage restraint. After the carrying strap is released, it easily curls outwards from the cup's side wall due to the elasticity of its material or external environmental factors, failing to fit snugly against the cup surface or be stored in a designated area. This curling not only detracts from the paper cup's overall aesthetics but also causes numerous inconveniences during actual use. For example, when holding the cup, the curled-out strap may interfere with the hand, affecting grip comfort; furthermore, it may snag on other items, causing damage or the cup to fall, severely impacting the user experience and the safety of the paper cup. Utility Model Content

[0005] The purpose of this invention is to provide a portable paper cup to overcome at least one of the aforementioned defects in the prior art.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] This utility model provides a paper cup for carrying, including an inner cup body, an outer cup body, a limiting seat, a limiting block, a carrying strap, and a locking part. The outer cup body is provided on the outer side wall of the inner cup body, and an accommodating space is formed between the inner cup body and the outer cup body. The limiting seats are symmetrically fixed on the left and right sides of the upper part of the accommodating space. The limiting seats have a first through hole in the middle. The bottom end of the carrying strap has a limiting block. The left and right sides of the top wall of the accommodating space have symmetrically provided second through holes. The top end of the carrying strap has a locking part, which passes through the first through hole and the second through hole and extends to the outer cup body. One of the carrying straps has a first locking hole, which engages with the locking part of the other carrying strap.

[0008] Preferably, a second locking hole is symmetrically provided on the lower part of the left and right side walls of the outer cup body, the second through hole is connected to the receiving space, and the locking part is engaged with the second locking hole.

[0009] Preferably, the card portion includes a connecting section and a protruding section. The top end of the carrying strap and the protruding section are connected by the connecting section. The width of the connecting section is less than the maximum width of the protruding section and less than the length of the second card hole. The minimum width of the protruding section is less than the length of the second card hole.

[0010] Preferably, the cross-section of the convex segment is trapezoidal.

[0011] Preferably, one leg of the trapezoid is equal to the width of the connecting segment and greater than the length of the other leg; the upper base of the trapezoid is less than the length of the second locking hole; and the lower base of the trapezoid is greater than the length of the second locking hole.

[0012] Preferably, the carrying strap, the limiting block, the connecting section, and the protruding section are integrally formed.

[0013] Preferably, the length of the first card hole is equal to the length of the second card hole.

[0014] Preferably, the top of the inner cup has a flange formed by the rolling up of the side wall, and a limiting space for inserting the card part is formed between the flange and the outer cup.

[0015] Preferably, the handle, inner cup body, and outer cup body are all made of coated kraft paper.

[0016] Preferably, the length of the limiting block is greater than the length of the first perforation and the second perforation.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By setting up an accommodating space formed by the inner and outer cup bodies, and cooperating with the guide and limiting of the limiting seat, the first perforation, and the second perforation, the carrying strap can be completely stored in the accommodating space when not in use, preventing the carrying strap from sticking out due to elastic recovery or external factors. This not only ensures the overall aesthetics of the paper cup, but also eliminates the interference of the sticking out carrying strap with the user's grip and the risk of snagging with other items, significantly improving the comfort and safety of use.

[0019] 2. Furthermore, the opening and closing of the carrying strap can be accomplished with just two simple actions: pulling the latch, engaging and disengaging the latch, and pressing to close it. The operation is easy and suitable for users of different ages.

[0020] 3. The first perforation of the limiting seat guides and limits the handle, preventing it from twisting or shifting during storage.

[0021] 4. The design of the second slot breaks through the single function limitation of existing paper cups that can only be carried by hand. Through simple bending and snapping operations, the carrying strap can be transformed into a handle structure, realizing the two-way switching between carrying by hand and holding by the handle, adapting to diverse usage needs.

[0022] 5. The card slot locks and unlocks with the second card slot through size matching, making the overall operation simple and the switching of states convenient.

[0023] 6. The limiting space allows the card to be inserted into the limiting space after the carrying strap is stored in the storage space, preventing the card from sticking out and affecting its use. Attached Figure Description

Detailed Implementation

[0036] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 11As shown, the paper cup provided in this embodiment includes an inner cup body 1, an outer cup body 2, a limiting seat 3, a limiting block 4, a carrying strap 5, and a locking part 6. The outer cup body 2 is provided on the outer side wall of the inner cup body 1, and an accommodating space 7 is formed between the inner cup body 1 and the outer cup body 2. The limiting seat 3 is symmetrically fixed on the left and right sides of the upper part of the accommodating space 7. The limiting seat 3 has a first through hole 31 in the middle. The bottom end of the carrying strap 5 has a limiting block 4. The left and right sides of the top wall of the accommodating space 7 have second through holes 8 symmetrically provided. The top end of the carrying strap 5 has a locking part 6. The locking part 6 passes through the first through hole 31 and the second through hole 8 and extends to the outside of the outer cup body 2. The carrying strap 5 on the right side has a first locking hole 51, which engages with the locking part 6 of the carrying strap 5 on the left side.

[0039] When a user needs to carry a paper cup using the carrying straps 5, an upward pulling force is first applied to the locking portions 6 of the two carrying straps 5 extending outside the outer cup body 2. The bottom ends of the carrying straps 5 are constrained by the limiting block 4 and the limiting seat 3 within the accommodating space 7. Specifically, the length of the limiting block 4 is greater than the length of the first perforation 31, preventing the carrying strap 5 from detaching from the first perforation 31. Because the limiting block 4 cooperates with the limiting seat 3, it does not act on the second perforation 8, preventing damage to the second perforation 8 and ensuring its integrity. Since the length of the limiting block 4 is greater than the length of the second perforation 8, the second perforation 8 can also block the limiting block 4 if the first perforation 31 fails, providing double protection.

[0040] When the user pulls the locking part 6 upwards, it causes the carrying strap 5 and the limiting block 4 to move upwards until the limiting block 4 is tightly fitted against the lower surface of the limiting seat 3. At this point, the carrying strap 5 is in a fully extended state. Then, the user aligns the locking part 6 of the left carrying strap 5 with the first locking hole 51 of the right carrying strap 5, applying pressure to force the locking part 6 through the first locking hole 51. The locking structure between the locking part 6 and the first locking hole 51 securely connects the two carrying straps 5. At this point, the two carrying straps 5 form a closed carrying loop above the cup body. The user can conveniently carry the paper cup by holding this carrying loop. During carrying, the limiting seat 3 limits the movement of the carrying straps 5 through the first through hole 31, preventing the carrying straps 5 from shifting and causing uneven force, thus ensuring carrying stability.

[0041] Thus, when the user does not need to carry the cup by hand and only needs to hold the cup or place the paper cup, first release the locking state of the two carrying straps 5. Then, the user presses the locking parts 6 of the two carrying straps 5 into the receiving space 7. Since the receiving space 7 is a closed area between the inner cup body 1 and the outer cup body 2, and the carrying straps 5 can move flexibly along the first perforation 31 and the second perforation 8, the locking parts 6 will cause the entire carrying strap 5 to retract into the receiving space 7 until only the locking parts 6 are exposed. During this process, the first perforation 31 of the limiting seat 3 guides and limits the carrying straps 5, preventing the carrying straps 5 from twisting or shifting when stored.

[0042] Compared to existing technologies where the carrying strap 5 is prone to warping due to its reliance on the tearing structure of the outer cup body 2, this invention addresses the shortcomings of existing technologies. By creating a receiving space 7 formed by the inner cup body 1 and the outer cup body 2, and using a limiting seat 3, a first perforation 31, and a second perforation 8 for guidance and limiting, the carrying strap 5 can be completely stored within the receiving space 7 when not in use. This prevents the carrying strap 5 from warping outwards due to elastic recovery or external factors. This not only ensures the overall aesthetics of the paper cup but also eliminates the interference of a warped carrying strap 5 with the user's grip and the risk of snagging on other items, significantly improving user comfort and safety.

[0043] Furthermore, the unfolding and folding of the carrying strap 5 can be accomplished with just two simple actions: pulling the latch 6 to engage and disengage, and then pressing to fold it away. This low barrier to entry makes it suitable for users of all ages. Whether carrying beverages, drinking directly from the cup, or placing the paper cup on a table or cup holder, the carrying strap 5 can be quickly adjusted to meet diverse usage needs, further enhancing the practicality and market competitiveness of the paper cup.

[0044] Among them, the lower sides of the left and right side walls of the outer cup body 2 are symmetrically provided with second locking holes 21, the second through hole 8 is connected to the accommodating space 7, and the locking part 6 is engaged with the second locking hole 21.

[0045] When the user needs a grip for assistance, first determine the initial state of the carrying strap 5: If the carrying strap 5 is in the retracted state, first pull the locking part 6 upwards until the limiting block 4 abuts against the lower surface of the limiting seat 3. If it is in the engaged state, release the engaged state. At this time, the carrying strap 5 is fully extended, providing sufficient bending length for subsequent bending to form a grip. After the carrying strap 5 is fully extended, the user bends the locking parts 6 of both carrying straps 5 outwards and downwards until the locking parts 6 move to the position of the second locking hole 21 below the outer cup body 2, and then inserts the locking parts 6 into the second locking hole 21 to engage with the second locking hole 21, so that the carrying strap 5 forms an arc-shaped grip structure, which is convenient for the user to hold. As needed, both left and right carrying straps 5 can be formed into a grip state, or only one side of the carrying strap 5 can be formed into a grip state, while the other side of the carrying strap 5 is retracted into the retracted state.

[0046] Thus, the design of the second slot 21 breaks through the limitation of existing paper cups that can only be carried by hand. Through a simple bending and snapping operation, the carrying strap 5 can be transformed into a handle structure, realizing a two-way switch between carrying by hand and holding by hand, adapting to diverse usage needs. For example, when carrying multiple drinks, users can carry them in batches through the carrying loop, and switch to handle mode when drinking individually. The hand does not need to directly contact the side wall of the cup, and the handle provides a more stable grip, solving the problems of slipping and hand fatigue caused by traditional paper cups. The handle function is achieved only by the cooperation of the second slot 21 and the original carrying strap 5, without the need for additional independent handle components. This simplifies the overall structure of the paper cup and avoids the increased cost and assembly complexity caused by additional components.

[0047] The card part 6 includes a connecting section 61 and a protruding section 62. The top of the carrying strap 5 is connected to the protruding section 62 via the connecting section 61. The width of the connecting section 61 is less than the maximum width of the protruding section 62 and less than the length of the second card hole 21. The minimum width of the protruding section 62 is less than the length of the second card hole 21. The cross-section of the protruding section 62 is trapezoidal. One leg of the trapezoid is equal to the width of the connecting section 61 and greater than the length of the other leg. The upper base of the trapezoid is less than the length of the second card hole 21, and the lower base of the trapezoid is greater than the length of the second card hole 21.

[0048] The locking part 6 achieves locking and unlocking with the second locking hole 21 through size matching: When locking, first tilt the protrusion 62 (long waist side near the second locking hole 21) through, and after the long waist and upper bottom are through, straighten it so that the short waist side is also through. When pushing the handle 5 to pull, because the lower bottom of the protrusion 62 is longer than the locking hole, the protrusion 62 is stuck and cannot be disengaged; when unlocking, remove the pull and push the handle 5 towards the long waist side, so that the short waist side is close to the edge of the second locking hole 21, and then tilt and push out the short waist side, upper bottom and long waist side. The length of the first locking hole 51 is equal to the length of the second locking hole 21. The locking part 6 and the first locking hole 51 have the same cooperation principle. The overall operation is simple and the switching of states is convenient.

[0049] The carrying strap 5, the limiting block 4, the connecting section 61, and the protruding section 62 are integrally molded. Specifically, they are cut from a strip of coated kraft paper. The integral molding ensures that the carrying strap 5, the limiting block 4, the connecting section 61, and the protruding section 62 have no seams, making the structure more stable and preventing breakage at the joints under stress. It also eliminates the splicing process, reducing production difficulty and cost.

[0050] The inner cup 1 has a flange 11 formed by the rolled-up side wall at its top, and a limiting space 9 is formed between the flange 11 and the outer cup 2 for inserting the card part 6. After the carrying strap 5 is stored in the receiving space 7, the card part 6 can be inserted into the limiting space 9 to prevent the card part from tilting outward and affecting its use.

[0051] The handle 5, inner cup 1, and outer cup 2 are all made of coated kraft paper. The use of coated kraft paper combines good tensile strength and water resistance, effectively improving the overall durability of the paper cup and ensuring its stable fit for everyday carrying and handheld use.

[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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 of the technical features.
