Description

Technical Field

[0001] This utility model relates to the field of hygiene products technology, specifically to a waterproof wet wipe packaging cover for use in bathroom environments. Background Technology

[0002] Wet wipes used in humid environments such as bathrooms (e.g., wet toilet paper, facial wipes) face unique packaging challenges: traditional wet wipe caps are primarily designed to prevent internal moisture evaporation, resulting in a relatively simple sealing structure. When the packaging is placed on a sink, in a shower spray area, or on a damp floor, external liquids can easily accumulate in the gaps between the cap and the base, and seep in due to capillary action or external pressure (such as being squeezed by other objects). This can lead to: 1. Contaminated wipes: Dirty water, shower gel foam, etc. from the outside enter the packaging and contaminate the sterile wipes inside.

[0003] 2. Bacterial growth: External moisture enters the packaging, damaging the original preservation system and providing conditions for bacterial growth.

[0004] 3. Product failure: The wipes become contaminated and cannot be used safely, resulting in waste.

[0005] The intrusion of external liquids can directly contaminate the internal wipes, breed bacteria, and cause the product to deteriorate and become ineffective, posing a health and safety hazard.

[0006] Utility model patent application number 202222461947.5 discloses a novel packaging box for wet toilet paper. The packaging box includes a box body, a top cover, a connecting shaft, side covers, a toilet paper alignment mechanism, and a waterproof shell. The box body has an opening on its upper side, with the top cover positioned at the opening to close it. Inside the box body is a connecting shaft with a paper roll wound around it, and an outlet at the lower end of the box body. The toilet paper alignment mechanism is located on the lower inner wall of the box body, and the waterproof shell is located at the lower end of the outer shell, directly opposite the outlet. The wet toilet paper can pass sequentially through the toilet paper alignment mechanism, the outlet, and the protective shell before entering the outside of the box body. This design features a wall-mounted packaging box with a waterproof shell at the bottom of the box body, blocking the outlet and preventing splashed water from entering the shell and contaminating the wet toilet paper. The toilet paper alignment mechanism inside the shell ensures that the wet toilet paper leaves the packaging box neatly.

[0007] This packaging box can significantly reduce the risk of contamination of wet wipes or toilet paper, but such packaging boxes need to be purchased separately. Many consumers will not consider purchasing them separately (some consumers may not have considered that wet wipes may be contaminated, and some consumers may consider that the packaging box is expensive), resulting in relatively poor practicality. Utility Model Content

[0008] This invention provides a waterproof wet wipe packaging cover for use in bathroom environments, in order to solve the technical problems in the prior art.

[0009] To solve the above problems, the waterproof wet wipe packaging cover for bathroom environments provided by this utility model adopts the following technical solution: it includes a base, which is fixedly connected to the perforated area of ​​the packaging bag, and the base has an inner ring opening for wet toilet paper to pass through; The cover is used to seal the base. The cover and the base are connected by a hinge, so that the cover can be rotated and opened about the hinge axis. The upper surface of the base is integrally formed with a ring-shaped vertical continuous guide strip. The outer side of the vertical continuous guide strip is provided with guide protrusions, which are used to guide water droplets so that the water droplets fall and prevent water droplets from accumulating.

[0010] As a further improvement, the outer side of the vertical continuous guide bar is 2mm away from the edge of the base.

[0011] As a further improvement, the height of the vertical continuous guide strip is 2mm-2.5mm.

[0012] As a further improvement, the guide protrusion is a trapezoidal guide protrusion, one side of which is in contact with the vertical continuous guide strip, and the other three sides of which are trapezoidal slopes to achieve sloped flow.

[0013] As a further improvement, the height of the trapezoidal guide protrusion is 2mm, the width of the bottom edge of the trapezoidal guide protrusion is 3mm, and the width of the top edge of the trapezoidal guide protrusion is 1.5mm-2mm.

[0014] As a further improvement, the interval between the trapezoidal guide protrusions is greater than 3cm.

[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. This utility model forms a physical barrier by setting vertical continuous guide strips, which helps to block external liquids and prevent liquids from seeping into the inside of the cover.

[0016] 2. The trapezoidal guide protrusions can disrupt water adhesion. When a small amount of water overflows from the gaps in the cover wall to the outer wall of the guide strip, the trapezoidal protrusions can disrupt the water's adhesion effect (Coanda effect) and surface tension, making it difficult for it to form a continuous water film. On the other hand, the trapezoidal guide protrusions can guide water flow differentiation. The inclined surface of the trapezoid can divide and guide the contacting water flow to both sides of the protrusion, causing it to drip in a discrete manner, further reducing the amount of water flowing into the internal sealing area.

[0017] 3. The vertical continuous guide strip and the trapezoidal guide protrusion work together. The vertical continuous guide strip blocks water droplets to the outside, while the trapezoidal guide protrusion plays a role in separating and guiding the flow, thus disrupting the continuity of the water film and preventing the formation of a siphon channel bridged by liquid water inside and outside the packaging cap.

[0020] 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.

[0021] In existing technology, the design of traditional wet wipe caps primarily focuses on preventing internal moisture evaporation, and their sealing structure is relatively simple. When the packaging is placed on a sink, in a shower spray area, or on a damp floor, external liquid can easily accumulate in the gap between the cap and the base, and seep into the interior due to capillary action or external pressure (such as being squeezed by other objects). Some existing packaging boxes optimize the seal to prevent wet wipes from becoming contaminated. However, most consumers do not purchase the packaging box separately, making these boxes relatively less practical.

[0022] To address the aforementioned issues, the present invention proposes a method that combines physical barriers with active diversion to fundamentally prevent external liquids from seeping into the packaging.

[0023] The vertical continuous guide strip is a continuous vertical strip with its root vertically connected to the inner edge of the sealing end face of the cover 2mm from the bottom. When water flows inward along the outer wall of the cover, the vertical guide strip can effectively cut off the water film, forcing the water to drip at its end instead of continuing to flow into the inner sealing area, thus achieving a primary physical blockage of most of the external water flow.

[0024] Trapezoidal guide protrusions can separate water flow and disrupt its surface tension, thus guiding the flow and making it difficult for it to form a continuous water film.

[0025] 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.

[0026] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0027] Example 1 of the waterproof wet wipe packaging cover for bathroom environments provided by this utility model: like Figures 1-3 As shown, the waterproof wipe packaging cover for bathroom environments includes a base 2 and a cover body 1 hinged to the base 2.

[0028] The base 2 is fixedly connected to the perforated area of ​​the packaging bag, and the base 2 has an inner ring opening for wet toilet paper to pass through.

[0029] The cover 1 is used to seal the base 2. The cover 1 and the base 2 are connected by a hinge, so that the cover 1 can rotate and open around the hinge axis.

[0030] The upper surface of the base 2 is integrally formed with a ring-shaped vertical continuous guide strip 3. The shape of the vertical continuous guide strip 3 is consistent with the shape of the base 2. In this embodiment, the outer side of the vertical continuous guide strip 3 is 2mm away from the edge of the base 2, and the height of the vertical continuous guide strip 3 is 2mm-2.5mm. In other embodiments, the size of the vertical continuous guide strip 3 can be adaptively adjusted according to the size of the wet wipe packaging bag.

[0031] The vertical continuous guide strip 3, acting as the first line of defense for the packaging cover, serves as a physical barrier and main gate at the forefront. Its primary function is to forcibly cut off the water film: in a bathroom environment, water typically seeps inward along the outer wall of the cover 1 in a "penetrating" manner. The vertical guide strip acts as a vertical, continuous barrier. When water seeps in, its flow path is forcibly interrupted, preventing it from continuing to flow into the more critical main sealing area inside. The vertical continuous guide strip 3 creates a physical height difference that must be overcome. Even if water attempts to rush inward due to inertia or external pressure, it must first overcome this vertical obstacle. This significantly increases the difficulty of water impacting the internal label, blocking most of the macroscopic, high-volume water flow outside the core area.

[0032] In addition, the vertical continuous guide strip 3 serves as the mounting base for the trapezoidal protrusions: it provides a structural carrier and support for the trapezoidal guide protrusions 4 of the second line of defense.

[0033] The outer surface of the vertical continuous guide strip 3 is provided with guide protrusions 4, which are used to guide water droplets so that they drip off and prevent water droplets from accumulating. The guide protrusions 4 are trapezoidal, with one side of each protrusion fitting against the vertical continuous guide strip 3, and the other three sides being trapezoidal slopes 5 to achieve sloped flow. In this embodiment, the height of the trapezoidal guide protrusions 4 is 2mm, the width of the base is 3mm, and the width of the top is 1.5mm-2mm. The intervals between the trapezoidal guide protrusions 4 are greater than 3cm.

[0034] In other embodiments, the guide protrusion 4 may also have an arc-shaped structure.

[0035] The trapezoidal guide bumps 4 are primarily used to disrupt the fluid adhesion effect and surface tension: even if water successfully adheres to the outer wall of the guide strip, attempting to form a larger water film to penetrate inwards, the trapezoidal bumps come into play. The discontinuous, angular geometry of the trapezoidal bumps brutally disrupts the continuity of the water film. It separates the water film, which attempts to form a continuous sheet, into discontinuous small water droplets, greatly weakening its ability to flow cooperatively.

[0036] The inclined surface of the trapezoid provides a clear, off-vertical path for the water droplets. When a droplet comes into contact with the inclined surface of the trapezoid's convex point, it is guided to both sides of the convex point, thus being dispersed and scattered, dripping in a discrete manner. This further reduces the amount of water flowing inward per unit area.

[0037] The working principle of this invention is based on the concept of prioritizing active flow guidance and supplementing it with physical sealing. Its working process is as follows: When the shower water splashes onto the closed cover 1, the water mainly flows downwards along the outer wall of the cover 1.

[0038] When water seeps into the gap between the cover 1 and the base 2, it first encounters the vertical continuous guide strip 3. This vertical continuous guide strip 3 acts as a vertical barrier, cutting off the path of the water flow and forcing most of the water flow to be isolated at the end edge of the guide strip. The water droplets gather and drip down, unable to approach the core sealing area.

[0039] When a large number of water droplets accumulate at the end of the vertical continuous guide strip 3, some droplets will cross the guide strip and enter the core sealing area. At this time, the trapezoidal guide protrusions 4 distributed on the outer wall of the guide strip come into play. Through their trapezoidal inclined surfaces, they divide and disperse the water film that is trying to form a continuous sheet, and guide it to drip discretely on both sides of the protrusions. This process greatly weakens the coordination and continuity of the water flow, making it unable to penetrate effectively.

[0040] System stability assurance: Since external liquid water is effectively blocked, no "siphon channel" bridged by liquid water will be formed inside and outside the packaging. Therefore, air pressure fluctuations caused by changes in bathroom temperature will not cause liquid seepage, and the system is stable and reliable in the long term.

[0041] 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.
