Abstract
Description
Technical Field
[0001] This utility model relates to the field of hygiene products technology, specifically to a sealed wet wipe cover that prevents microbial contamination. Background Technology
[0002] Humans have extremely high safety requirements for cleaning products that come into direct contact with the body. Currently, the packaging of wet wipes and toilet paper can achieve a sealing and contamination-preventing effect when unopened; however, once opened or when the contents decrease, the adhesive labels may not adhere properly to the soft packaging film, leading to air leakage. With poorly adhered labels and numerous gaps in the lid, wet wipes and toilet paper, left in a damp environment with high microbial content for extended periods, easily become breeding grounds for microorganisms, posing serious risks to human health. For example, pathogenic bacteria (such as Staphylococcus aureus) can cause allergic reactions such as redness and itching, and may lead to purulent infections if there are open wounds; E. coli can cause urinary tract infections, and in severe cases, pyelonephritis and intestinal infections; mold can release toxins (such as aflatoxin), and long-term exposure can increase the risk of cancer. Especially during special periods (such as menstruation, periods of skin damage, etc.), for people with hemorrhoids, or for people with fragile skin barriers, microorganisms are more likely to invade the bloodstream, which may lead to systemic infectious diseases such as sepsis in severe cases.
[0003] Utility model patent application number 2024204705299 discloses a wet wipe cover with a sealing structure. This disclosed solution addresses two problems with existing wet wipe covers: sealing and difficulty in opening. To address these issues, the disclosed solution uses an outer frame and a magnetic sealing mechanism, employing a sliding method to open and close the wet wipe cover, thus achieving both a tight seal and convenient opening and closing.
[0004] However, the raw material and production costs of the wet wipe cap in this publicly disclosed design are higher than those of conventional plastic wet wipe caps, which leads to a higher price for the entire pack of wet wipes. For most consumers, while safety and hygiene are important considerations, price is also a factor, meaning that the aforementioned wet wipes can only meet the needs of a minority of consumers. Utility Model Content
[0005] This invention provides a sealed wet wipe cover to prevent microbial contamination, thereby solving the technical problem of secondary contamination caused by poor sealing of existing wet wipes or wet toilet paper during long-term use.
[0006] To solve the above problems, the sealing wet wipe cover for preventing microbial contamination provided by this utility model adopts the following technical solution: it includes a lower cover body connected to the wet wipe packaging bag, an upper cover body for cooperating with the lower cover body, and a hinge for connecting the lower cover body and the upper cover body. The lower cover body has an opening for taking out the wet wipe.
[0007] An annular lower cover sealing ring is provided at the edge of the opening. The bottom surface of the upper cover body is provided with an upper cover outer sealing ring and an upper cover inner sealing ring that cooperate with the lower cover sealing ring. The upper cover outer sealing ring and the upper cover inner sealing ring are spaced apart, so that after the lower cover body and the upper cover body are fastened together, the lower cover sealing ring is inserted into the gap between the upper cover outer sealing ring and the upper cover inner sealing ring, and the lower cover sealing ring is tightly fitted with the upper cover outer sealing ring and the upper cover inner sealing ring respectively.
[0008] As a further improvement, the cross-section of the gap between the outer sealing ring and the inner sealing ring of the upper cover is narrow at the top and wide at the bottom, so that the lower sealing ring can be accurately inserted into the gap between the outer sealing ring and the inner sealing ring of the upper cover, while ensuring that the lower sealing ring is tightly fitted with the outer sealing ring and the inner sealing ring of the upper cover respectively.
[0009] As a further improvement, the cross-section of the gap between the outer sealing ring and the inner sealing ring of the upper cover is an inverted V-shape or an inverted Y-shape.
[0010] As a further improvement, both the lower cover body and the upper cover body have inclined surfaces on their sides to prevent moisture accumulation.
[0011] As a further improvement, the lower edge of the upper cover body is 0.5 mm wider than the upper edge of the lower cover body.
[0012] As a further improvement, the upper cover body is provided with a fastening component on the side opposite to the hinge. The fastening component has an arc-shaped structure to increase the contact area between the fingers and the fastening component and improve comfort.
[0013] As a further improvement, the lower cover sealing ring is higher than the lower cover body to prevent the wet tissue from leaking liquid from the opening in the lower cover body when it is squeezed.
[0014] As a further improvement, the height of the lower cover sealing ring is 38% higher than that of the lower cover body.
[0015] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:
[0016] 1. This utility model has an inclined surface. After the lower cover body and the upper cover body are fastened together, the overall front view is a trapezoidal structure, which is conducive to water sliding off the edge and preventing water accumulation. Moreover, the edges and corners of the cover are smoother and more rounded than those of a right-angled slope, improving the feel and preventing the edges from cutting your hands.
[0017] The lower edge of the upper cover is 0.5mm wider than the upper edge of the lower cover, creating a design that mimics a double-eaved hip roof around the edge of the cover. This helps guide water from the edge of the upper cover to the lower cover, reducing the amount of water that remains in the gap between the upper and lower covers and thus reducing the growth of microorganisms.
[0018] 2. The cross-section of the gap between the outer sealing ring and the inner sealing ring of the upper cover is an inverted Y shape. The upper width of the gap between the outer sealing ring and the inner sealing ring of the upper cover is the same as the width of the sealing ring of the lower cover, which can make the sealing ring of the lower cover fit perfectly and greatly improve the sealing performance.
[0019] When wet wipes are used for an extended period of time, the plastic wet wipe cover may deform. In addition, the lower cover and the upper cover are hinged. If a structure with consistent spacing between the upper and lower covers is used, misalignment may occur during fastening, making it difficult to fasten and thus causing sealing problems.
[0020] The inverted Y-shaped structure gradually increases in size as it approaches the bottom. When the parts are fastened, this structure acts as a guide to ensure that the lower cover sealing ring is precisely fitted into the gap between the upper cover outer sealing ring and the upper cover inner sealing ring.
[0021] When opening the main body of the cover, the inverted Y-shaped structure also ensures that the resistance encountered when the lower cover sealing ring separates from the upper cover outer sealing ring and the upper cover inner sealing ring is reduced, making it easier to open and close the cover.
[0022] 3. The sealing part adopts a redundant sealing design with three sealing rings: the lower cover sealing ring, the upper cover outer sealing ring, and the upper cover inner sealing ring. The superimposed structure of the three sealing rings forces water vapor to go through multiple up and down turns before it can enter the inside of the wet wipe from the outside or evaporate from the wet wipe to the outside. Compared with no sealing or single-layer sealing structure, this invention multiplies the movement trajectory of water vapor evaporation, strongly avoiding the possibility of sealing failure. It can not only prevent external microbial contamination, but also firmly lock in the moisture carried by the wet wipe itself, improve the safety of use, and extend the service life.
[0023] 4. The arc-shaped fastening part increases the contact area with the fingers, and the fastening part is relatively flat and long, with a length of about 1 / 2 of the width of the main body of the cover, which can better fit the fingers and make it easier to open the cover.
[0024] 5. The height of the lower cover sealing ring is 38% higher than the lower cover body, so that it can contact the upper cover body when fastened. This height design of the lower cover sealing ring can effectively prevent water from flowing out when the wet wipe is squeezed and the liquid leaks from the extraction point.
[0025] 6. By improving the sealing of the wet wipe cap, the adhesive label can be discarded after the first peel-off during use, reducing the need for subsequent peeling and sticking of adhesive labels. This allows for a three-step usage process: opening the cap, taking out the wet wipe, and closing the cap, greatly improving ease of use. Attached Figure Description

[0035] 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.
[0036] In existing technologies, when wet wipes or wet toilet paper are opened or the contents decrease, the adhesive labels adhere unevenly to the flexible packaging film, resulting in localized poor adhesion and air leakage. With labels not properly attached and numerous gaps in the lid, wet wipes and wet toilet paper are left in a damp environment with high microbial content for extended periods, easily becoming a breeding ground for microorganisms and posing a serious threat to human health.
[0037] To address the aforementioned issues, this invention first improves the side surface of the wet wipe cover by changing it to an inclined surface, resulting in an overall trapezoidal structure. This facilitates the sliding of water from the edge and prevents water accumulation, thereby reducing the growth of microorganisms.
[0038] Secondly, the sealing structure has been improved. The cross-section of the gap between the outer sealing ring and the inner sealing ring of the upper cover is an inverted Y shape. The upper width of the gap between the outer sealing ring and the inner sealing ring of the upper cover is the same as the width of the sealing ring of the lower cover, which can make the sealing ring of the lower cover fit perfectly and greatly improve the sealing performance.
[0039] Finally, the user experience was optimized by adjusting the height of the fastening components and the sealing ring on the lower cover.
[0040] 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.
[0041] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0042] Example 1 of the antimicrobial contamination sealing wet wipe cap provided by this utility model:
[0043] like Figures 1-6 As shown, the anti-microbial contamination sealed wet wipe cap includes a lower cover body 2 connected to the wet wipe packaging bag, an upper cover body 1 for cooperating with the lower cover body 2, and a hinge 3 for connecting the lower cover body 2 and the upper cover body 1. The lower cover body 2 has an opening 10 for pulling out wet wipes, and the opening 10 has a rounded rectangular structure. The upper cover body 1 has an upper cover fastener 5, and the lower cover body 2 has a lower cover fastener 6 that cooperates with the upper cover fastener 5. The upper cover body 1 and the lower cover body 2 are fastened together by the upper cover fastener 5 and the lower cover fastener 6. The above are all conventional designs for wet wipe caps, and the specific structure will not be described in detail.
[0044] like Figure 2 As shown, both the lower cover body 2 and the upper cover body 1 have inclined surfaces on their sides to prevent water accumulation. After the lower cover body 2 and the upper cover body 1 are fastened together, the overall front view has a trapezoidal structure, which is conducive to water sliding off the edges and preventing water accumulation.
[0045] like Figure 4 As shown, the lower edge of the upper cover body 1 is 0.5mm wider than the upper edge of the lower cover body 2, so that the edges of the cover body form an eaves-like design, which helps to guide water from the edge of the upper cover body 1 to the lower cover body 2, reducing the amount of water that stays in the gap between the upper cover body 1 and the lower cover body 2, thereby reducing the growth of microorganisms.
[0046] like Figure 1 and Figure 2 As shown, a fastening component 4 is provided on the side of the upper cover body 1 opposite to the hinge 3. The fastening component 4 has an arc-shaped structure, which increases the contact area with the fingers. The fastening component 4 is relatively flat and long, with a length that accounts for about 1 / 2 of the width of the upper cover body 1. The width of the fastening component 4 is 2-7mm, which can be adjusted according to the size of the cover. Compared with the commonly used straight shape, this shape increases the contact area by about 8 times, which can better fit the fingers and make it easier to open the cover.
[0047] like Figure 5 and Figure 6 As shown, an annular lower cover sealing ring 9 is provided at the edge of the opening 10. The bottom surface of the upper cover body 1 is provided with an upper cover outer sealing ring 7 and an upper cover inner sealing ring 8 that cooperate with the lower cover sealing ring 9. The upper cover outer sealing ring 7 and the upper cover inner sealing ring 8 are spaced apart, so that after the lower cover body 2 and the upper cover body 1 are fastened together, the lower cover sealing ring 9 is inserted into the gap between the upper cover outer sealing ring 7 and the upper cover inner sealing ring 8, and the lower cover sealing ring 9 is tightly fitted with the upper cover outer sealing ring 7 and the upper cover inner sealing ring 8 respectively. This three-layer sealing ring structure forces water vapor to go through multiple up and down turns before it can enter the wet wipe from the outside or evaporate from the wet wipe to the outside, which multiplies the movement trajectory of water vapor evaporation and ensures its sealing performance.
[0048] The cross-section of the gap between the outer sealing ring 7 and the inner sealing ring 8 of the upper cover is narrow at the top and wide at the bottom, which allows the lower sealing ring 9 to be precisely inserted into the gap between the outer sealing ring 7 and the inner sealing ring 8 of the upper cover, while ensuring that the lower sealing ring 9 is tightly fitted with the outer sealing ring 7 and the inner sealing ring 8 of the upper cover respectively.
[0049] In this embodiment, the cross-section of the gap between the outer sealing ring 7 and the inner sealing ring 8 of the upper cover is an inverted Y shape. In other embodiments, the cross-section can also be an inverted V shape.
[0050] like Figure 5 As shown, during the downward pressing process of the upper cover body 1, the lower cover sealing ring 9 intersects with the upper cover outer sealing ring 7 and the upper cover inner sealing ring 8 at points a and b. At this time, the distance from point a to the upper cover body 1 is L1, and the opening and closing angle of the upper cover body 1 is α. It can be seen that compared with the straight interval, the inverted Y-shaped interval L1 is shorter and the angle α is smaller, that is, the degree of deformation of the upper cover sealing ring and the closing resistance are greatly reduced when the cover is closed.
[0051] like Figure 3 As shown, the height of the lower cover sealing ring 9 is higher than that of the lower cover body 2, that is, the lower cover sealing ring 9 is higher than the upper end face of the lower cover body 2, in order to prevent the wet tissue from leaking out of the opening 10 of the lower cover body 2 when it is squeezed. In this embodiment, the height of the lower cover sealing ring 9 is 38% higher than that of the lower cover body, ensuring that the lower cover sealing ring 9 can contact the upper cover body 1 when it is fastened.
[0052] The height of the outer sealing ring 7 and the inner sealing ring 8 of the upper cover is less than that of the upper cover body 1. The height of the outer sealing ring 7 and the inner sealing ring 8 is 2.5-3mm. Testing showed that even if the height of the outer sealing ring 7 and the inner sealing ring 8 is adjusted to be the same as that of the lower cover sealing ring 9, the sealing effect is not significantly different from that when the height of the outer sealing ring 7 and the inner sealing ring 8 is 2.5-3mm. Therefore, the height of the outer sealing ring 7 and the inner sealing ring 8 can be lower. This ensures a good sealing effect, reduces opening and closing resistance, and also reduces material usage and raw material costs.
[0053] 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.
