Description

Technical Field

[0001] The present invention relates to the field of wet wipes, and particularly to an improved wet wipe laminated structure and its packaging product. Background Art

[0002] In order to improve space utilization, wet wipes usually need to be placed in a packaging in a laminated structure, and two adjacent wet wipes in the upper and lower layers are simply clamped by the laminated structure, which is convenient for continuous extraction during the use of wet wipes.

[0003] Actually, both of the two adjacent wet wipes in the upper and lower layers contain liquid, and the surface tension of the liquid causes the wet wipes in the upper and lower layers to be closely joined to each other. Therefore, during the extraction of wet wipes, there is a problem that it is easy to cause multiple upper and lower layers of wet wipes to be extracted together. In order to avoid multiple upper and lower layers of wet wipes being extracted together, it is necessary to reduce the joining force. In the prior art, a patent with the publication number CN1123317C discloses a wet tissue laminate and a wet tissue product containing the laminate. A material with different smoothness on both sides is used as the base material of the wet tissue. The joining force of the smooth surface is low, while the joining force of the non-smooth surface is high, effectively reducing the risk of multiple upper and lower layers of wet wipes being extracted together. However, the production of the base material with different smoothness on both sides is difficult and costly.

[0004] In addition, after the upper wet wipe is extracted, the end of the lower wet wipe is clamped out of the wet wipe outlet for a certain distance to facilitate subsequent extraction and use. However, the part of the end of the lower wet wipe clamped out of the wet wipe outlet is not stable and is easy to fall back into the packaging, which is not conducive to subsequent use. Especially as the number of wet wipes in the packaging decreases during the extraction of wet wipes, the part of the end of the lower wet wipe clamped out of the wet wipe outlet cannot be effectively supported and is more likely to fall back into the packaging, which needs to be improved. Summary of the Invention

[0005] The purpose of the present invention is to provide an improved wet wipe laminated structure and its packaging product, which reduces the risk of multiple upper and lower layers of wet wipes being extracted together and improves the continuity and stability of extraction and use.

[0006] To achieve this purpose, the present invention adopts the following technical solutions:

[0007] An improved wet wipe laminated structure includes: several wet wipes stacked up and down. Each wet wipe respectively includes a middle part, a first folding part and a second folding part. The first folding part and the second folding part are located at both ends of the middle part. The first folding part of the lower wet wipe bends upward from one end of the middle part and then extends to the middle part of the upper wet wipe above it. The second folding part bends downward from the other end of the middle part and then extends to the middle part. A first abrasive part is arranged on the surface of the second folding part facing the middle part.

[0008] Wherein, a second abrasive part corresponding to the first abrasive part is arranged on one side of the middle part facing the second folding part.

[0009] Wherein, the first folding part and the second folding part are located at both ends in the width direction of the middle part.

[0010] Wherein, the projected area of the first folding part on the middle part is less than half of the area of the middle part.

[0011] Wherein, the projected area of the second folding part on the middle part is less than half of the area of the middle part.

[0012] To achieve this purpose, the present invention adopts the following another technical solution:

[0013] A wet wipe packaging product, comprising: a packaging body and wet wipes, and the wet wipes are placed in the packaging body in the above-mentioned improved wet wipe laminated structure.

[0014] Wherein, a wet wipe outlet is arranged on the packaging body, and the packaging body adopts a packaging box or a packaging bag.

[0015] Wherein, a cover ring covering the wet wipe outlet is arranged on the packaging body, a cover body is rotatably arranged on the cover ring, a flexible film is arranged below the cover body in the wet wipe outlet or the cover ring, and a wet wipe extraction slit is arranged in the flexible film.

[0016] Wherein, an elastic piece is arranged on the bottom surface of the cover body and extends obliquely and passes above the wet wipe extraction slit.

[0017] Wherein, the cover ring, the cover body and the elastic piece adopt an integrated plastic structure.

[0018] The beneficial effects of the present invention: An improved wet wipe laminated structure and its packaging product. The wet wipes can use non-woven fabric materials with high double-sided smoothness as the base material, avoiding the risk of multiple wet wipes being pulled out together, and there is no need to use base materials with different smoothness on both sides, reducing the processing cost. The first abrasive part is used to strengthen the joint state between the second folding part and the middle part during the extraction process, reducing the contact between the second folding part and the first folding part of the lower wet wipe, further controlling the distance that the first folding part of the lower wet wipe is pulled out together. The bending and elastic clamping of the first folding part by the elastic piece during the closing process of the cover ring avoid the problem of the first folding part retracting into the packaging body, facilitating subsequent extraction and improving the continuity and process stability of wet wipe extraction and use.

[0021] Figure 3 is a schematic structural view of the wet wipe packaging product of the present invention;

[0023] Figure 5 is Figure 4 a schematic structural view after the lid in Detailed implementation manners

[0024] The following combines Figures 1 to 5 and further illustrates the technical solution of the present invention through specific embodiments.

[0025] Such as Figure 1 and Figure 2 shown, the improved wet wipe laminated structure includes:

[0026] Such as Figure 1 shown, the improved wet wipe laminated structure includes: several wet wipes 1 stacked up and down, each wet wipe 1 respectively includes a middle part 13, a first folding part 11 and a second folding part 12, the first folding part 11 and the second folding part 12 are located at both ends of the middle part 13, in this embodiment, the first folding part 11 and the second folding part 12 are located at both ends in the width direction of the middle part 13, forming a rectangular three-fold structure, which is beneficial to reducing the width of the package 2.

[0027] The first folding part of the lower wet wipe is bent upward from one end of the middle part and then extends to the middle of the middle part 13 of the upper wet wipe 1 above it, and the stacked structure is used to realize the clamping of the upper and lower wet wipes 1.

[0028] The second folding part 12 is bent downward from the other end of the middle part 13 and then extends to the middle of the middle part 13. In this embodiment, the projected area of the first folding part 11 on the middle part is less than half of the area of the middle part 13, and the projected area of the second folding part 12 on the middle part 13 is less than half of the area of the middle part 13, that is to say, neither the first folding part 11 nor the second folding part 12 crosses the midline of the middle part 13 during the folding process, but the front ends of the first folding part 11 and the second folding part 12 are relatively close to the midline, reducing the overall width while reducing the production difficulty of folding.

[0029] To improve the stability of the second folding part 12 during the extraction process of the wet wipe 1, it is necessary to maintain the engagement between the second folding part 12 and the middle part 13. If the second folding part 12 flips open during the extraction process, it will increase the contact area between the second folding part 12 and the first folding part of the lower wet wipe, increase the height at which the first folding part of the lower wet wipe is pulled upward together, and even increase the risk that the lower wet wipe is completely pulled out together with the upper wet wipe.

[0030] Therefore, in the present application, a first abrasive part 14 is provided on the surface of the second folding part 12 facing the middle part. The first abrasive part 14 reduces the smoothness of the surface of the second folding part 12 facing the middle part. Under the action of the liquid surface tension of the wet wipe, the first abrasive part 14 and the middle part 13 are closely engaged with each other.

[0031] In addition, as Figure 2 shown, a second abrasive part 15 corresponding to the first abrasive part 14 is provided on the surface of the middle part 13 facing the second folding part. The second abrasive part 15 intersects with the first abrasive part 14. Under the action of the liquid surface tension, the bonding force between the second folding part 12 and the middle part 13 is further increased, and the separation problem between the second folding part 12 and the middle part 13 during the extraction process is reduced. In this embodiment, the second abrasive part 15 and the first abrasive part 14 are strip-shaped or dot-shaped fluff areas generated on the corresponding surfaces of the middle part 13 and the second folding part 12 through an abrasive process, and the processing cost is low.

[0032] In this embodiment, the middle part 13, the first folding part 11, and the second folding part 12 adopt an integrated non-woven fabric structure, which is beneficial to folding with a non-woven fabric having a high smoothness on both sides, and there is no need to use a non-woven fabric substrate with different smoothness on both sides, reducing the difficulty and cost of processing the non-woven fabric substrate.

[0033] As Figures 3 to 5 shown, the wet wipe packaging product includes: a packaging 2 and a wet wipe 1. The wet wipe 1 is placed in the packaging 2 in the above-mentioned improved wet wipe laminated structure. A wet wipe extraction opening 21 is provided on the packaging 2, which is convenient for extracting the wet wipe 1. In this embodiment, the packaging 2 adopts a packaging box or a packaging bag, and the selection is flexible.

[0034] A retaining ring 3 covering the wet wipe extraction opening 21 is provided on the packaging 2. The bottom surface of the retaining ring 3 can be fixed on the packaging 2 by a hot pressing process or an adhesive, and the structure is firm. A cover body 31 is rotatably provided on the retaining ring 3. A connecting part connected to the retaining ring 3 is integrally provided at the tail of the cover body 31. A buckle is provided at the front end of the cover body 31, which cooperates with the card slot on the retaining ring 3 after closing to lock the cover body 31, and the airtight effect is good, reducing the evaporation of the liquid in the wet wipe 1 in the packaging 2.

[0035] As Figure 3As shown in the figure, a flexible film 4 is provided in the wet wipe outlet 21 or the cover ring 3 below the cover body 31, and the flexible film 4 is used to block the wet wipe outlet 21. In this embodiment, a wet wipe extraction slit 41 is provided in the flexible film 4, and the width of the wet wipe extraction slit 41 only allows the second folding portion 12 and the middle portion 13 to be extracted upward simultaneously. The flexible film 4 is made of silica gel material and has a certain elasticity, and can be fixed in the cover ring 3 by a two-shot injection molding process, with a stable structure.

[0036] When the wet wipe 1 is taken out upward for the first time, the wet wipe extraction slit 41 can be enlarged by force, the topmost wet wipe 1 can be lifted out, and the first folding portion of the lower wet wipes can be extended upward out of the wet wipe extraction slit 41 for a certain distance to facilitate subsequent extraction.

[0037] Furthermore, in order to facilitate the subsequent extraction of the wet wipes, it is necessary to limit the first folding portion to prevent the first folding portion extending out of the wet wipe extraction slit 41 from slipping into the packaging 2. As Figure 3 shown in the figure, a spring piece 32 is provided on the bottom surface of the cover body 31, which extends obliquely and passes above the wet wipe extraction slit 41. In this embodiment, the cover ring 3, the cover body 31 and the spring piece 32 are made of an integrated plastic structure, which is convenient for production.

[0038] As Figure 4 shown in the figure, during the closing process of the cover body 31, the first folding portion is bent on the flexible film 4 through the flipping and elastic deformation of the spring piece 32, and the first folding portion is elastically clamped through the cooperation of the spring piece 32 and the flexible film 4 to prevent the first folding portion from slipping into the packaging 2, improving the stability.

[0039] As Figure 5 shown in the figure, after the cover body 31 is opened, the first folding portion adheres to the top surface of the flexible film 4, which is convenient for the extraction action of the wet wipes.

[0040] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
