Description

Technical Field

[0001] This utility model relates to the field of wet wipes technology, specifically a wet wipe cover with a self-locking support structure. Background Technology

[0002] In daily life and healthcare, flip-top wet wipe packaging is widely used due to its ease of use and good sealing properties. Existing wet wipe lids typically consist of a base plate and a cover plate connected to it by a hinge. To use, the user must manually flip open the cover plate and hold it in place to remove the wet wipes.

[0003] However, in real-world applications, such as when a user is holding a child or has contaminated hands, it is difficult to simultaneously open and close the lid with one hand. If the lid is fully opened, due to its lack of a positioning function, it will automatically close or wobble under the influence of gravity or the elasticity of the hinge, interfering with the extraction process and making it very inconvenient to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wet tissue cover with a self-locking support structure. By setting the self-locking support structure, the problem of the wet tissue cover not being able to fix itself after opening, which affects one-handed use, is solved. The cover can automatically stabilize at the maximum opening angle after opening, so that users can completely free their hands to take out tissues, greatly improving the convenience of operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wet tissue cover with a self-locking support structure, comprising a connecting mounting part and a sealing cover plate; The sealing cover plate is provided with two first partition grooves, which divide the sealing cover plate into a movable plate and a mounting plate. The mounting plate is fixedly connected to the mounting part. The sealing cover plate is also provided with a second partition groove. The edge of the second partition groove forms a hinge with the two first partition grooves. The second partition groove separates the movable plate to form a self-locking support protrusion for support.

[0006] Furthermore, the two ends of the self-locking support protrusion are straight grooves, and the middle part is an arc-shaped groove. The arc-shaped groove causes an arc-shaped self-locking support protrusion to be formed on the movable plate.

[0007] Furthermore, one end of the movable plate is provided with an opening latch for easy opening and closing.

[0008] Furthermore, the movable plate and the mounting part are connected by adhesive.

[0009] Furthermore, a sealing plate for sealing is provided on the side of the movable plate facing the mounting part.

[0010] Furthermore, the mounting part includes a support plate for connecting and supporting the wet wipe container. The support plate has a sealing groove in the middle that is adapted to it, and the sealing groove has a pull-out groove in the middle that facilitates the removal of the wet wipe.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects: I. This wet wipe cover with a self-locking support structure features an innovative groove structure design that integrates the hinge, movable cover plate, and self-locking support protrusion onto a single sealing cover plate, achieving functional integration of components. This structure utilizes the material's own elastic deformation to automatically lock the cover plate when opened to a specific angle, stably maintaining the open state. This completely solves the pain point of traditional wet wipe covers requiring manual support, greatly facilitating one-handed use of wet wipes, and is especially suitable for scenarios involving holding a baby or those with limited hand mobility.

[0012] Second, this wet wipe cover with a self-locking support structure eliminates the need for complex springs, gears, and other additional parts, significantly simplifying mold manufacturing and product assembly processes and effectively reducing production costs. Simultaneously, the sealing plate on the inner side of the movable cover and the sealing groove on the mounting part fit tightly together, ensuring excellent sealing performance when the cover is closed. This effectively prevents moisture evaporation from the wet wipes, keeping them clean and moist, thus combining superior functionality with economy. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] A wet wipe lid with a self-locking support structure mainly includes an mounting part 1 and a sealing cover plate 2. The mounting part 1 is used to connect to and support the opening of the wet wipe container (such as a bucket, bag, etc.). The sealing cover plate 2 achieves automatic support function for the movable part through a specific groove structure design.

[0017] Specifically, the sealing cover 2 has two first dividing grooves 21. These two first dividing grooves 21 are parallel to each other, dividing the main body of the sealing cover 2 into a movable plate 22 and a mounting plate 23 located behind the movable plate 22. The mounting plate 23 is firmly connected to the mounting part 1 by adhesive or other fixing methods, thereby fixing the entire sealing cover 2.

[0018] To achieve the hinge and self-locking of the movable plate 22, a second partition groove 24 is also provided on the sealing cover plate 2. This second partition groove 24 is located between the two first partition grooves 21. Thus, the edge of the second partition groove 24 and the two first partition grooves 21 together define a flexible hinge portion 25. At the same time, the second partition groove 24 separates a key self-locking support protrusion 26 in the front region of the movable plate 22.

[0019] Preferably, the shape of the self-locking support protrusion 26 is determined by the shape of the second dividing grooves 24 on both sides: its two ends are straight groove segments, and the middle part is an arc-shaped groove segment that is recessed towards the movable plate 22. This design makes the final self-locking support protrusion 26 an arc-shaped spring sheet structure with both sides connected to the main body of the movable plate 22.

[0020] To facilitate user opening, an upwardly protruding opening latch 27 is provided at the end of the movable plate 22 away from the hinge portion 25 (i.e., the front end).

[0021] Regarding sealing, an annular sealing plate 28 is provided on the side of the movable plate 22 facing the mounting part 1. Correspondingly, the mounting part 1 includes an annular support plate 11 for connecting and supporting the wet wipe container. An annular sealing groove 12 adapted to the shape of the sealing plate 28 is formed in the middle of the support plate 11. When the movable plate 22 is closed, the sealing plate 28 is pressed into the sealing groove 12, forming a tight seal. In the middle of the sealing groove 12, a pull-out groove 13 is provided to facilitate the removal of the wet wipe.

[0022] Working principle: In the closed state, the movable plate 22 achieves sealing through the cooperation of the sealing plate 28 and the sealing groove 12.

[0023] When the user uses their finger to pry open the latch 27 and flip the movable plate 22 upwards, the movable plate 22 rotates around the hinge 25 made of flexible material. As the opening angle increases, the self-locking support protrusion 26 on the inner side of the movable plate 22 gradually contacts, presses against, and eventually slides past the upper surface of the support plate 11 of the mounting part 1 (i.e., the area surrounding the sealing groove 12). Utilizing the elastic deformation and arc structure of the material itself, self-locking is achieved when the maximum opening angle (usually 90 degrees or greater) is reached. At this point, even if the user releases their hand, the movable plate 26 can remain stably in the open state due to the interaction between the self-locking support protrusion 26 and the support plate 11, and will not close on its own, making it convenient for the user to remove wet wipes with one hand.

[0024] When closed, only a pressure slightly greater than the self-locking force needs to be applied to cause the self-locking support protrusion 26 to undergo elastic deformation and slide back into the sealing groove 12, restoring the closed and sealed state.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
