[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.
[0026] Example 1
[0027] Please refer to Figure 1-Figure 7 As shown, a waterproof sealed storage bag includes a bag body 1 and a fixing belt 101. The fixing belt 101 is fixedly connected to the upper end of the outer side of the bag body 1 by hot pressing. A self-sealing zipper 3 is provided inside the fixing belt 101. The self-sealing zipper 3 includes two sets of sealing guide rails 301 and two sets of sealing strips 302. The sealing guide rails 301 are fixedly connected to one side of the interior of the fixing belt 101, and the sealing strips 302 are fixedly connected to the other side of the interior of the fixing belt 101. The sealing strips 302 are snapped into the interior of the sealing guide rails 301. The bag body 1 includes a printed coating 203. A waterproof layer 204 is provided on the front side of the printed coating 203, and a wear-resistant layer 205 is provided on the front side of the waterproof layer 204.
[0028] In this solution, the upper opening of the bag body 1 can be sealed by fastening the sealing strip 302 to the inside of the sealing guide rail 301. By providing a waterproof layer 204 and a wear-resistant layer 205 on the outside of the printed coating 203, the printing on the printed coating 203 can be prevented from being eroded by water and from being removed by external friction, thereby ensuring the dryness and safety of stored items. This solution is particularly suitable for use in humid environments or for storing items that require waterproof protection, and also protects the integrity and beauty of the printing.
[0029] Furthermore, the printed coating 203 uses a PU coating, which is a polyurethane coating technology. It is a polymer compound containing an -NHCOO- unit in its molecular structure. The unit is formed by the reaction of an isocyanate group and a hydroxyl group. The coating is soft and elastic; the coating has good strength and can be used for very thin coatings. The desired pattern can be printed through the coating.
[0030] Furthermore, the waterproof layer 204 is made of polyurethane material, which has the characteristics of low water permeability, good softness, elasticity, and high tensile strength, effectively preventing the interior of the storage bag from being eroded by internal and external moisture, and ensuring that the moisture inside the storage bag is not exposed;
[0031] Furthermore, the wear-resistant layer 205 is made of Cordura nylon material, which has the advantages of good wear resistance, tear resistance, texture strength, and is not easy to change color after long-term use.
[0032] Example 2
[0033] Please refer to Figure 5-Figure 6 As shown, a plurality of mounting grooves 207 are provided on the front side of the wear-resistant layer 205 , and wear-resistant protrusions 206 are bonded into the mounting grooves 207 . The wear-resistant protrusions 206 are evenly arranged at equal distances and distributed in a rectangular array.
[0034] The bag body 1 further comprises a base layer 2 , and a pull-resistant layer 201 is provided on the front side of the base layer 2 .
[0035] A frosted layer 202 is provided on the front side of the pull-resistant layer 201 , and a printed coating 203 is provided on the front side of the frosted layer 202 .
[0036] The base layer 2, the pull-resistant layer 201, the frosted layer 202, the printed coating 203, the waterproof layer 204 and the wear-resistant layer 205 are all connected in sequence by hot-melt adhesive.
[0037] In this solution, the base layer 2 is made of polyethylene material, which is non-toxic and harmless and has good flexibility and basic structural support;
[0038] Furthermore, the pull-resistant layer 201 is made of polyester fiber material, and the polyester fiber has good wrinkle resistance and shape retention, thereby making the bag body 1 have higher strength and elastic recovery ability, thereby making the bag body 1 more durable;
[0039] Furthermore, the frosted layer 202 is made of frosted material. The matte frosted material mainly produces a matte or masked effect, achieving a matte light-transmitting and opaque effect, which can provide privacy protection for items stored inside the bag body 1.
[0040] Furthermore, the wear-resistant layer 205 and the wear-resistant protrusions 206 provided thereon not only improve the wear resistance of the surface of the bag body 1 and extend its service life, but also enhance the anti-slip performance when holding through its special structural design, thereby improving the user experience.
[0041] Example 3
[0042] Please refer to Figure 4 As shown, at least three sets of fixed pen caps 102 are provided on one side of the bag body 1, and a secondary bag 103 is provided on the other side of the bag body 1. The fixed pen caps 102 and the secondary bag 103 are connected to the front and back sides of the bag body 1 by hot pressing.
[0043] The bag body 1 consists of two bag surfaces of the same size. The two sets of bag surfaces are sealed on three sides by heat pressing, and a bag opening is left on the top.
[0044] In this solution, the fixed pen cover 102 and the auxiliary bag 103 provided in the bag body 1 provide space for classified storage of stationery or small items of different sizes, thereby improving the neatness of storage and the convenience of access.
[0045] The working principle and usage process of the present invention are as follows: First, by fastening the sealing strip 302 to the inside of the sealing guide rail 301, the bag opening at the upper end of the bag body 1 can be sealed; by separating the sealing strip 302 from the sealing guide rail 301, the bag opening can be opened to place items; by arranging a waterproof layer 204 and a wear-resistant layer 205 on the outside of the printed coating 203, the print on the printed coating 203 can be prevented from being eroded by water, and the print can be prevented from being eliminated by external friction, thereby protecting the integrity and beauty of the print; by arranging a wear-resistant protrusion 206 on the wear-resistant layer 205, the wear resistance of the surface of the bag body 1 is improved, the service life is extended, and the anti-slip performance when holding is enhanced.
[0046] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
