Abstract
Description
A wet wipe lid that is easy to open and close and has a good seal. Technical Field
[0001] This utility model relates to the field of hygiene products technology, specifically to a wet wipe lid that is easy to open and close and has good sealing performance. Background Technology
[0002] In the field of personal hygiene products, wet toilet paper and wipes provide users with a more comfortable cleaning experience due to their softness and moisture, but their packaging design and opening / closing methods affect the user experience.
[0003] Most existing wet toilet paper packaging caps use a flip-top design, which is acceptable initially, but is prone to loosening due to material aging, wear, or design flaws, resulting in poor sealing and allowing the wet toilet paper to easily become damp and dry, affecting its hygienic performance. While tightening the snap can improve the seal, it makes opening and closing less convenient, a common problem with many wet wipe caps, requiring both hands or extra force, causing inconvenience to users.
[0004] While some patent documents propose improvement solutions, most only address one aspect: sealing or ease of opening and closing, failing to comprehensively solve the problem. For example, designs that prioritize sealing often sacrifice ease of opening and closing, requiring extra force or tools to open; while designs that prioritize ease of opening and closing often lack sufficient sealing, making wet toilet paper susceptible to contamination or accelerating drying.
[0005] Some patent documents address the issues of sealing and ease of opening and closing wet wipe lids by modifying their form. For example, utility model patent application number 2024203470012 discloses an easy-to-open wet wipe lid. This application states that "existing wet wipe boxes, after being opened, use a wet wipe lid to seal the inside of the box to ensure sealing. However, to maintain this seal, the lid and box close very tightly. Furthermore, because current wet wipe lids and boxes are mostly snap-fit type to save costs and for ease of use, opening and closing the lid is laborious and inconvenient." To solve these problems, this application provides both an opening / closing component and a sealing component, thus resolving the issues raised in the application.
[0006] Prolonged use leads to aging and wear on the wet wipe lid, resulting in poor sealing, primarily in large-sized wet wipe bags. Many consumers purchase these products mainly because of the relatively lower cost of larger bags. However, the opening and closing components in the aforementioned solution include parts such as a toothed rack and spring, increasing raw material and assembly costs. This ultimately raises the price of the entire bag of wet wipes, making it difficult to simultaneously meet most consumers' needs for affordable, well-sealed, and easy-to-open large-sized wet wipe bags. Summary of the Invention
[0007] This invention provides a wet wipe lid that is easy to open and close and has good sealing performance, so as to solve the technical problems of ease of one-handed operation and sealing performance in the prior art.
[0008] To solve the above problems, the wet wipe lid provided by this utility model, which is easy to open and close and has good sealing performance, adopts the following technical solution:
[0009] Includes a base, which is fixedly connected to the packaging bag, and the base has an opening for pulling out tissues;
[0010] The cover, which is used to seal the base, is connected to the base by a hinge, allowing the cover to rotate and open about the axis of the hinge.
[0011] The top cover buckle is located on the side wall at the front end of the cover body; the side wall at the front end of the base is provided with a bottom buckle that cooperates with the top cover buckle. The top cover buckle and the bottom buckle cooperate with each other to lock and unlock the cover body.
[0012] The front sidewall of the cover has an arc-shaped recessed structure, which forms a protruding handle at the front end of the cover. When the cover is fastened to the base, the handle, the recessed structure, and the front end of the base form an opening groove into which a finger can be inserted.
[0013] As a further improvement, the base has an annular bottom sealing strip at the opening, and the bottom of the cover has a top sealing strip that cooperates with the bottom sealing strip.
[0014] As a further improvement, the bottom sealing strip and the top cover sealing strip are misaligned, so that when the cover is fastened, the bottom sealing strip and the top cover sealing strip are interlocked, and the misalignment deformation angle of the top cover sealing strip is 1°-20°.
[0015] As a further improvement, the top cover buckle is located on the inner side wall of the front end of the cover body.
[0016] As a further improvement, both the base and the cover are trapezoidal structures.
[0017] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0018] 1. Enables one-handed operation, improving convenience. This utility model features a handle. When opening the cover, the thumb inserts under the handle, and the index finger presses against the center of the top of the cover. When the thumb applies force, the front end of the cover deforms, and the position of the top cover latch shifts, allowing the top cover latch to easily separate from the bottom latch. This reduces the force required to open the cover, saving 2-10 times the effort compared to conventional two-handed opening.
[0019] 2. Excellent sealing performance. When the lid is closed, the bottom sealing strip and the top sealing strip interlock and fit tightly together, ensuring the wet wipe lid is airtight. In addition, the dimensions of the top and bottom latches have been adjusted, and the thickness of the protruding sidewalls of the top and bottom latches has been slightly increased to ensure that the top and bottom latches can still be stably engaged after long-term use and wear.
[0020] Generally, increasing the size of the top and bottom latches improves their locking effect, ensuring a secure fit even after prolonged use. However, this also requires more force to open the lid. This invention, by incorporating a handle and lever principle, deforms the front of the lid upon opening, causing the top latch to shift position and allowing for easy opening. This design ensures the wet wipe lid remains securely closed even after extended use and allows for easy one-handed opening.
[0021] 3. More stable structure. When the lid is fastened, it exhibits a double-gradient fastening. In the first stage, the hinge and two auxiliary fastening points at the rear end of the base form a triangular fastening. In the second stage, the two auxiliary fastening points at the rear end of the base and the two auxiliary fastening points at the front end form a trapezoidal fastening. This two-stage double-gradient fastening ensures the stability of the lid. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0030] In existing technologies, there is a contradiction between sealing and convenience in wet wipe caps. Designs that prioritize sealing often sacrifice ease of opening and closing, requiring extra force or tools to open; while designs that prioritize ease of opening and closing often lack sufficient sealing, making wet toilet paper susceptible to contamination or faster drying.
[0031] To address the aforementioned issues, this invention firstly incorporates a handle, providing a leverage point for one-handed operation. When the cover needs to be opened, the thumb inserts into the opening groove, and the index finger presses against the center of the top of the cover. When the thumb applies force, the front end of the cover deforms, causing the top cover latch to shift position, allowing the top cover latch to easily separate from the bottom latch, thereby reducing the force required to open the cover.
[0032] Secondly, the sealing performance is improved in two ways. On the one hand, the bottom sealing strip and the top cover sealing strip are staggered. After they are fastened together, the bottom sealing strip and the top cover sealing strip interlock and fit tightly together, ensuring the sealing performance of the wet wipe lid.
[0033] On the other hand, the dimensions of the top cover buckle and the bottom buckle were also adjusted, and the thickness of the top cover buckle and the bottom buckle protruding from the side wall was slightly increased to ensure that the top cover buckle and the bottom buckle can still be stably fastened after long-term use and wear.
[0034] Generally, increasing the size of the top and bottom latches improves their locking effect, ensuring a secure fit even after prolonged use. However, this also requires more force to open the lid. This invention, by incorporating a handle and lever principle, deforms the front of the lid upon opening, causing the top latch to shift position and allowing for easy opening. This design ensures the wet wipe lid remains securely closed even after extended use and allows for easy one-handed opening.
[0035] Finally, by using auxiliary fasteners one, two, three, and four to limit the travel of the cover during fastening, the stability and durability of the structure are ensured.
[0036] When the lid is fastened, it exhibits a dual-gradient fastening mechanism. In the first stage, a triangular fastening is formed by the hinge and auxiliary fastening positions one and two. During the fastening process, the lid first contacts auxiliary fastening positions one and two, which at this time play a certain guiding role, ensuring that the lid can accurately fasten to the base as it continues to fasten. In the second stage, a trapezoidal fastening is formed by two auxiliary fastening positions at the rear end and two auxiliary fastening positions at the front end of the base. This dual-gradient fastening mechanism ensures the stability of the lid.
[0037] In addition to limiting the closing stroke of the cover, the auxiliary fastener can also hold the cover in place, preventing it from loosening due to prolonged use and causing it to wobble after being fastened.
[0038] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.
[0039] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0040] Embodiment 1 of the wet wipe lid provided by this utility model, which is easy to open and close and has good sealing performance:
[0041] As shown in Figures 1-4, the easy-to-open and well-sealed wet wipe lid includes a base 2 connected to the wet wipe packaging bag, and a cover 1 connected to the base 2 via a hinge 5. The cover 1 can rotate to open and close about the axis of the hinge 5. The wet wipes mentioned here include, but are not limited to, wet wipes and wet toilet paper.
[0042] The base 2 and the cover 1 are trapezoidal in shape and rounded at the four corners. The base 2 has an opening for pulling out tissues.
[0043] A top cover buckle 10 is integrally formed on the inner side wall of the front side wall of the cover 1. The thickness of the top cover buckle 10 is 0.5-3mm, ensuring that the cover 1 can still be firmly fastened to the base 2 even after long-term use. The front side wall of the base 2 is provided with a bottom buckle 11 that cooperates with the top cover buckle 10. The top cover buckle 10 and the bottom buckle 11 cooperate with each other to lock and unlock the cover 1.
[0044] The front side wall of the cover 1 is provided with an arc-shaped recessed structure, so that the front end of the cover 1 forms a protruding handle 12; when the cover 1 and the base 2 are fastened together, the handle 12, the recessed structure and the front end of the base 2 form a cover opening groove into which a finger can be inserted.
[0045] The base 2 has an annular bottom sealing strip 4 at its opening, and the cover 1 has a top sealing strip 3 at its bottom that cooperates with the bottom sealing strip 4. The bottom sealing strip 4 and the top sealing strip 3 are offset so that when the cover 1 is fastened, the bottom sealing strip 4 and the top sealing strip 3 are interlocked, and the offset deformation angle of the top sealing strip 3 is 1°-20°.
[0046] The base 2 is also equipped with auxiliary fasteners 6, 7, 8, and 9 at its four corners. Auxiliary fastener 6 is a protruding structure protruding from the side wall of the base 2, with a thickness of 0.1-1mm. Auxiliary fasteners 7, 8, and 9 have the same structure as auxiliary fastener 6. The four auxiliary fasteners 6 serve two purposes: first, to limit the travel trajectory of the cover 1 when it is fastened, thus acting as a guide; and second, to prevent gaps between the cover 1 and the base 2 when it is fastened after prolonged use, which could cause the cover 1 to wobble.
[0047] While this specification has shown and described numerous embodiments of the present invention, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of the present invention. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
