Description

Technical Field

[0001] This utility model relates to the field of home textile technology, specifically to a pillowcase with a double-layer anti-leakage lining. Background Technology

[0002] Pillowcases are a common household textile product used in daily life. They are mainly used to cover the outside of pillow cores to protect them, facilitate cleaning, and improve comfort. Currently, there are many types of pillowcases on the market, made of various materials such as cotton, chemical fibers, and silk.

[0003] For pillowcases filled with down, down-filled cotton, or other similar materials, traditional pillowcases often suffer from poor lint-proof performance. Traditional pillowcases are mostly single-layered, or even if double-layered, the layers are not tightly connected, and the fabric density is insufficient. Over time, down can easily escape through fabric gaps or stitching, affecting not only the pillowcase's appearance but also potentially causing users to inhale the down, leading to respiratory discomfort, especially for those with allergies. Furthermore, the leaked down can stain sheets, blankets, and other bedding, increasing the cleaning burden. Therefore, developing a double-layered pillowcase with excellent lint-proof performance is of significant practical value. Utility Model Content

[0004] The purpose of this invention is to provide a pillowcase with a double-layer leak-proof velvet lining to solve the defects mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A double-layered leak-proof lining pillowcase includes an outer pillowcase body with a first zipper at the bottom. An inner leak-proof lining is located inside the outer pillowcase body, comprising a first inner lining layer and a second inner lining layer. A buffer layer is provided between the first and second inner lining layers. An opening gap is provided at the opening of the first and second inner lining layers, and a first sealing strip and a second sealing strip are provided at the opening gap. The two ends of the first and second sealing strips are respectively fixedly installed on the corresponding first and second inner lining layers. A second zipper is provided on both the first and second sealing strips.

[0007] Preferably, a zippered cover is fixedly installed at the bottom of the outer pillowcase body, and when the zippered cover is closed, the first zipper is tucked inside.

[0008] This design prevents the first zipper from coming into direct contact with the user's skin, thus avoiding discomfort, and also prevents lint from leaking out from the zipper gaps.

[0009] Preferably, one side of the zipper cover is provided with a front operating gap, which is connected to the outside.

[0010] This setting allows the first zipper to be operated normally in the front operating gap area.

[0011] Preferably, the outer pillowcase body is composed of a base layer disposed on the innermost layer, an antibacterial layer disposed on the outer surface of the base layer, and a breathable and wear-resistant surface layer disposed on the outer surface of the antibacterial layer.

[0012] Preferably, the first inner liner layer is filled with a pillow core, and the inner surface of the first inner liner layer is provided with a plurality of anti-slip protrusions.

[0013] This feature increases the friction between the pillow and the pillow core, preventing the pillow core from sliding in the first inner layer during use, thereby reducing the amount of fibers that need to be pushed out due to friction.

[0014] Preferably, the edges of the first inner liner and the second inner liner are connected by double-line binding sutures, with the sutures being tight and slanted and intersecting.

[0015] Preferably, a sealing strip is also provided at the edge seam of the inner leak-proof lining, and the sealing strip covers the seam after double-line binding.

[0016] This feature allows the sealing strip to further seal the pinholes, enhancing the leak-proof effect.

[0017] Preferably, the first zipper is arranged along the width direction of the outer pillowcase body, and the second zipper is also arranged along the width direction of the outer pillowcase body.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model features an inner lining that prevents the leakage of down, consisting of a first inner lining layer, a second inner lining layer, and a buffer layer. The first and second sealing strips at the opening gaps are closed by a second zipper, which, together with the outer pillowcase body, provides further protection, forming a multi-layered structure that effectively blocks down from leaking out through gaps and seams.

[0020] 2. This utility model provides a first zipper and a zipper cover cloth at the bottom of the outer pillowcase body. When the zipper cover cloth is closed, it wraps around the first zipper. At the same time, the outer pillowcase body adopts a composite structure of a base layer, an antibacterial layer, and a breathable and wear-resistant surface layer. This achieves the effect of covering and protecting the zipper gap and improving the overall performance, thereby preventing the zipper from leaking and enhancing the safety and durability of use.

[0021] 3. This utility model increases the friction with the pillow core by setting multiple anti-slip protrusions on the inner surface of the first inner liner layer, preventing the pillow core from sliding and causing the fluff to come out. At the same time, the front operating gap facilitates the operation of the first zipper, achieving a combination of stability and ease of operation during use, thus improving the user experience.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-4This utility model provides a technical solution: a double-layer leak-proof pillowcase, including an outer pillowcase body 1, a first zipper 10 at the bottom of the outer pillowcase body 1, an inner leak-proof lining 2 inside the outer pillowcase body 1, the inner leak-proof lining 2 including a first inner lining layer 20 and a second inner lining layer 21, a buffer layer 22 between the first inner lining layer 20 and the second inner lining layer 21, an opening gap 23 at the opening of the first inner lining layer 20 and the second inner lining layer 21, a first sealing strip 24 and a second sealing strip 25 at the opening gap 23, the two ends of the first sealing strip 24 and the second sealing strip 25 are respectively fixedly installed on the corresponding first inner lining layer 20 and the second inner lining layer 21, and a second zipper 26 is provided on both the first sealing strip 24 and the second sealing strip 25, so that the multi-layer structure and the double zipper form a three-dimensional leak-proof barrier to prevent the lint from leaking out from the opening.

[0031] like Figure 1 and Figure 2 As shown, a zipper cover 11 is fixedly installed at the bottom of the outer pillowcase body 1. When the zipper cover 11 is closed, the first zipper 10 is covered inside, which can prevent the first zipper 10 from directly contacting the user's skin and causing discomfort, and at the same time prevent the lint from leaking out from the zipper gap. A front operation gap 12 is provided on one side of the zipper cover 11. The front operation gap 12 is connected to the outside, so that the first zipper 10 can be operated normally at the front operation gap 12.

[0032] like Figure 4 As shown, the outer pillowcase body 1 consists of a base layer 13 set in the innermost layer, an antibacterial layer 14 set on the outer surface of the base layer 13, and a breathable and wear-resistant surface layer 15 set on the outer surface of the antibacterial layer 14. The base layer ensures basic strength, the antibacterial layer reduces bacterial growth, and the breathable and wear-resistant surface layer improves durability and breathability, taking into account both hygiene and practicality.

[0033] It is worth noting that the antibacterial layer 14 can be made of polyester fiber with added silver ion antibacterial agent. Silver ions can destroy bacterial cell membranes and maintain antibacterial effect for a long time. At the same time, the toughness of polyester fiber helps to improve the overall durability of the outer pillowcase body 1.

[0034] like Figure 1 and Figure 2 As shown, the first inner liner layer 20 is filled with a pillow core. Multiple anti-slip protrusions 28 are provided on the inner surface of the first inner liner layer 20 to increase the friction between the anti-slip protrusions 28 and the pillow core, prevent the pillow core from sliding and causing the fluff to come out, and maintain the stability of the pillow core position.

[0035] In addition, the edges of the first inner liner layer 20 and the second inner liner layer 21 are connected by double-line binding sutures, and the sutures are tight and obliquely cross-shaped; a sealing strip 27 is also provided at the edge suture of the inner layer leak-proof lining 2. After the double-line binding sutures, the sealing strip 27 covers the sutures, which reduces the gap of the needle hole by the double-line sutures, and the sealing strip 27 further seals the leakage channel and strengthens the edge leak-proof effect.

[0036] In this embodiment, the first zipper 10 is arranged along the width direction of the outer pillowcase body 1, and the second zipper 26 is also arranged along the width direction of the outer pillowcase body 1, so that the opening and closing direction of the zipper is adapted to the force direction of the pillowcase, reducing the leakage of down due to the stretching and deformation of the zipper during use, and improving the sealing performance of the zipper.

[0037] When using the double-layer leak-proof down-filled pillowcase of this utility model, first open the first zipper 10 through the front operating gap 12 of the zipper covering cloth 11 at the bottom of the outer pillowcase body 1, take out the inner leak-proof down-filled liner 2, open the second zipper 26 on the first sealing strip 24 and the second sealing strip 25, and put the pillow core into the first inner liner layer 20 through the opening gap 23. The anti-slip protrusions 28 on the inner surface of the first inner liner layer 20 can fix the position of the pillow core.

[0038] Close the second zipper 26 to seal the opening gap 23 with the first sealing strip 24 and the second sealing strip 25. The double-line binding stitching of the edges of the first inner liner 20 and the second inner liner 21 and the sealing strip 27 enhance the leak-proof performance. Put the inner leak-proof fleece liner 2 back into the outer pillowcase body 1, pull the first zipper 10, and close the zipper cover cloth 11 to wrap the first zipper 10.

[0039] During use, the base layer 13, antibacterial layer 14, and breathable and wear-resistant surface layer 15 of the outer pillowcase body 1 ensure comfort and hygiene. When cleaning, repeat the opening steps to remove the inner leak-proof fleece liner 2 and clean the outer pillowcase body 1 and the inner leak-proof fleece liner 2 respectively.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
