Description

Technical Field

[0001] The present invention relates to the field of wet wipes, and particularly to a slow-release wet wipe based on essential oil microcapsules. Background Art

[0002] In order to extend the release time of essential oils in wet wipes, essential oil microcapsules can be used. The essential oil microcapsules are sprayed on the surface of the wet wipes, and the slow release of essential oils occurs during use. In addition, when using the wet wipes to wipe the skin or articles, the essential oils can also be transferred to the surface of the skin or articles.

[0003] The high wall density of the essential oil microcapsules causes the essential oil microcapsules to sink in the liquid medicine of the wet wipes. In the existing wet wipe packages, usually dozens of wet wipes are stacked in the packaging bag. Therefore, the essential oil microcapsules in the upper wet wipes will sink in the liquid medicine and flow to the bottom of the packaging bag along with the liquid medicine, greatly reducing the actual amount of essential oil microcapsules in the upper wet wipes, and the distribution of the essential oil microcapsules on the wet wipes is also uneven, making it inconvenient to use and needing improvement. Summary of the Invention

[0018] Figure 2 is Figure 1 the top view of

[0019] Figure 3 is a schematic structural diagram of another embodiment of the present invention. Detailed Embodiments

[0020] The following combines Figures 1 to 3 and further illustrates the technical solutions of the present invention through specific embodiments.

[0021] Such as Figure 1 the slow-release wet wipe based on essential oil microcapsules shown, including: essential oil microcapsules 4, a first non-woven fabric layer 1, a second non-woven fabric layer 2, and a third non-woven fabric layer 3. The first non-woven fabric layer 1 is arranged on the top surface of the second non-woven fabric layer 2, and the third non-woven fabric layer 3 is arranged on the bottom surface of the second non-woven fabric layer 2, adopting a three-layer composite structure.

[0022] In this embodiment, the first non-woven fabric layer 1 and the second non-woven fabric layer 2 adopt pure cotton non-woven fabric, and the pure cotton non-woven fabric has a soft and comfortable touch and has no adverse effects on the human body. The third non-woven fabric layer 3 can adopt polyester non-woven fabric to reduce costs.

[0023] Cavities 9 are arranged at intervals on the second non-woven fabric layer 2, and the essential oil microcapsules 4 are arranged in the cavities 9, such as Figure 2As shown, the cavity 9 is distributed in a rectangular array, which improves the uniformity of the distribution of the essential oil microcapsules 4 and avoids the problem of the essential oil microcapsules 4 flowing with the liquid medicine.

[0024] In this embodiment, the essential oil microcapsule 4 includes a capsule wall and an essential oil core embedded in the capsule wall. The essential oil core uses natural plant essential oil, which is natural, pollution-free and environmentally friendly. The characteristics of the natural plant essential oil itself are used to improve the use effect. For example, jasmine essential oil has an elegant smell and can improve the problem of dry skin. The material of the capsule wall can be polylactic acid. The capsule wall made of polylactic acid is insoluble in water at room temperature, avoiding the dissolution problem in the wet wipe liquid medicine and ensuring the sustained release effect of the essential oil.

[0025] A first annular sealing groove 5 is recessed in the top surface of the first non-woven fabric layer 1. The first annular sealing groove 5 is concentrically arranged outside the cavity 9. A second annular sealing groove 7 is recessed in the bottom surface of the third non-woven fabric layer 3. The second annular sealing groove 7 is directly below the first annular sealing groove 5. The first annular sealing groove 5 and the second annular sealing groove 7 are formed by hot pressing, which can not only realize the hot pressing and compounding of the first non-woven fabric layer 1, the second non-woven fabric layer 2 and the third non-woven fabric layer 3, but also realize the decoration of the wet wipe surface and increase the friction force, thereby improving the effect during cleaning use.

[0026] In addition, after the first annular sealing groove 5 and the second annular sealing groove 7 are formed by hot pressing, a sealing effect is formed around the cavity 9, avoiding the essential oil microcapsules 4 from entering the interlayer between the first non-woven fabric layer 1 and the second non-woven fabric layer 2 or the interlayer between the second non-woven fabric layer 2 and the third non-woven fabric layer 3, further avoiding the problem of the essential oil microcapsules 4 flowing with the liquid medicine, and having high position stability.

[0027] As Figure 1 shown, in order to facilitate the extrusion of the essential oil microcapsules 4, a first pressing groove 6 located above the cavity 9 is recessed in the top surface of the first non-woven fabric layer 1. A first convex surface 11 extending into the cavity is provided on the bottom surface of the first non-woven fabric layer 1. After the first pressing groove 6 is stressed, the essential oil microcapsules 4 can be extruded through the first convex surface 11.

[0028] A second pressing groove 8 located below the cavity 9 is recessed in the bottom surface of the third non-woven fabric layer 3. A second convex surface 12 extending into the cavity 9 is provided on the top surface of the third non-woven fabric layer 3. After the second pressing groove 8 is stressed, the essential oil microcapsules 4 can be extruded through the second convex surface 12, causing the capsule wall of the essential oil microcapsules 4 to rupture and accelerating the sustained release of the essential oil. The operation is simple and the use is more flexible.

[0029] As Figure 3As shown, in this embodiment, foam filter beads 10 are provided in the cavity 9, and at least part of the essential oil capsule core is filled in the voids of the foam filter beads 10. The foam filter beads 10 are made of polyurethane foam filter beads and have good elasticity.

[0030] The elastic protection of this part of the essential oil capsule core is carried out through the foam filter beads 10, the shock absorption effect is improved, the problem of capsule wall rupture caused by vibration during the transportation and packaging of the essential oil microcapsules 4 is reduced, the integrity of the capsule wall is improved, and it is beneficial to ensure the sustained release effect during use.

[0031] The above content is only a 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 manners and application scopes. The content of this specification should not be construed as a limitation to the present invention.
