Abstract
Description
Technical Field
[0001] This utility model relates to the field of trousers with absorbent pads, and more particularly to a type of stain-resistant trousers that absorbs liquid and has a side panel sewn onto the trousers by means of a waterproof layer. Background Technology
[0002] Adult incontinence is receiving increasing attention. For users, a stable connection structure in the absorbent area is a key factor in product design, directly impacting ease of use and comfort. However, existing absorbent pants often use simple attachment methods, resulting in an unstable bond between the absorbent pad and the pant body. This leads to the pad easily shifting or loosening during daily activities, reducing absorbency and increasing discomfort. Therefore, designing an effective connection structure between the absorbent area and the pant body has become a primary requirement for improving the performance of absorbent pants.
[0003] Currently, the methods for fixing the absorbent area are mostly simple insertion or attachment, which makes the absorbent pad prone to displacement or deformation during use, thus affecting the absorbency and wearing stability. Furthermore, traditional absorbent pad structures lack effective integration with the pant body, failing to form a stable and efficient absorbent system. These shortcomings make existing products prone to problems after prolonged wear.
[0004] In addition, when sewing is used to fix the absorbent pad to the pants, the needle holes can penetrate the waterproof layer, allowing liquid to easily seep into the pants through the needle holes and seams due to capillary action, resulting in liquid leakage.
[0005] In view of the defects in the known connection methods between absorbent pads and pants, such as liquid leakage through pinholes and liquid seeping into the pants through the sewn threads due to capillary action, the inventor of this utility model has been actively and continuously developing a utility model that can improve the above problems. Utility Model Content
[0006] The main objective of this invention is to provide a type of stain-resistant trousers that uses a seepage-proof edge to connect to the trouser body, preventing liquid leakage from the connection between the absorbent pad and the trouser body or any holes created by the connection. This ensures that the liquid remains reliably within the structure of the absorbent pad.
[0007] Another objective of this invention is to utilize a reverse-folding and covering fixing structure to ensure that after the absorbent layer and waterproof layer are sewn, the seam is still covered by the waterproof layer, preventing liquid from seeping out through the seam or holes due to capillary action, and also preventing discomfort caused by friction between the seam and human skin.
[0008] To achieve the aforementioned objectives, the present invention provides absorbent and stain-resistant trousers, comprising: a trouser body and an absorbent pad body, wherein the inner side of the trouser body is the side that contacts the wearer's skin, and the opposite side is the outer side. One end of the trouser body has an opening, and the other end has two openings, allowing the wearer to insert their feet into the trouser body through the opening and exit through the openings. The opening faces upwards, and the openings face downwards; viewed from the inside of the trouser body towards the outside, the left and right sides are the left and right sides, respectively.
[0009] The absorbent pad body is disposed on the inner side of the pants and has the following components: an absorbent layer, a waterproof layer, a waterproof edge, and a skin-friendly layer. The absorbent layer absorbs liquid; the waterproof layer covers one side of the absorbent layer to prevent liquid from seeping into the pants from the absorbent layer; the side of the waterproof layer in contact with the absorbent layer is the waterproof inner surface, and the opposite side is the waterproof outer surface; the waterproof edge is disposed at the edge of the absorbent pad body, forming a liquid retention space together with the waterproof layer on the inner side of the pants; and the skin-friendly layer is disposed on the other side of the absorbent layer in contact with the waterproof layer and is made of a skin-friendly material.
[0010] In a preferred embodiment of this invention, the absorbent layer, waterproof layer, impermeable edge, and skin-friendly layer are all interconnected by a folded-overlay fixing structure. The folded-overlay fixing structure consists of the impermeable edge, skin-friendly layer, absorbent layer, and waterproof layer stacked sequentially from top to bottom. The edge of the waterproof layer is folded upwards, and then folded back towards the inner waterproof surface, allowing the outer waterproof surface to contact the impermeable edge. A fixing member passes sequentially through the inner waterproof surface of the folded waterproof layer edge, the outer waterproof surface, the impermeable edge, the skin-friendly layer, and the absorbent layer to complete the fixing connection.
[0011] In a preferred embodiment of this invention, the absorbent pad body is connected to the pant body by a connector at one end of its waterproof edge away from the absorbent pad body using a connection method. This prevents liquid from seeping into the pant body through pinholes or the connector because the connector penetrates the waterproof layer.
[0012] In a preferred embodiment of this utility model, anti-permeability edges are provided on the lower, left, and right sides of the absorbent pad body, and the three anti-permeability edges are integrally formed to prevent liquid from seeping into the trouser body from the joints of the anti-permeability edges.
[0013] Preferably, the anti-seepage edge is also located on the top of the absorbent pad body to prevent liquid or other substances from seeping upwards into the pants.
[0014] In a preferred embodiment of the present invention, the waterproof layer further has a folded portion, which is formed by folding the edge of the waterproof layer from the outer waterproof surface toward the inner waterproof surface.
[0015] Ideally, the waterproof layer and the impermeable edge are integrally formed.
[0016] Preferably, the connection method can be a method of passing the connector through the trouser body and the waterproof edge, and more preferably, it can be sewing.
[0017] Preferably, there can be multiple absorbent layers to increase the effectiveness of liquid absorption.
[0018] In a preferred embodiment of this utility model, the absorbent pad body is trapezoidal, preferably with the upper side of the trapezoid wider than the lower side, for receiving liquid.
[0019] Preferably, the width of the absorbent pad body is 10 to 20 centimeters. Attached Figure Description

[0040] 2: Pants Detailed Implementation
[0041] To facilitate understanding of this utility model, it will be described in detail below with reference to the accompanying drawings and embodiments. The drawings show some, but not all, embodiments of this utility model. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without any inventive effort are within the scope of protection of this utility model.
[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0043] Figures 1 to 5 This is a schematic diagram of an embodiment of the present utility model, as shown below. Figure 1 As shown in the partial schematic diagram of the embodiment of this utility model from an inner, forward-facing perspective, the absorbent and stain-resistant pants of this utility model include: a pant body 2 and an absorbent pad body 1. The pant body 2 has an opening on one side and two openings on the other side, allowing the wearer to insert their feet into the pant body 2 through the openings and then pull them out through the openings. Further, the front of the pant body 2 is the crotch area; the back is the crotch area; and the bottom is the bottom crotch area.
[0044] like Figure 2 for Figure 1As shown in the cross-sectional schematic diagram of the first embodiment of this utility model in the AA direction, the absorbent pad body 1 is disposed on the inner side of the crotch area of the pants body 2, and the absorbent pad body 1 has: an absorbent layer 11, a waterproof layer 12, an anti-permeability edge 13, and a skin-friendly layer 14. The absorbent layer 11 absorbs liquid, reduces liquid spillage, and retains the liquid within its structure. The waterproof layer 12 covers one side of the absorbent layer 11 to prevent liquid from penetrating through the absorbent layer 11 and entering the pants body 2. The side of the waterproof layer 12 that contacts the absorbent layer 11 is the waterproof inner surface 121, and the opposite side is the waterproof outer surface 122. The anti-permeability edge 13 is made of waterproof material and is disposed at the edge of the absorbent pad body 1, forming a liquid retention space together with the waterproof layer 12 on the inner side of the pants body 2 to prevent liquid from entering the pants body 2. The skin-friendly layer 14 is disposed on the other side of the absorbent layer 11 that contacts the waterproof layer 12, and is made of skin-friendly material to reduce discomfort for the wearer and prevent the absorbent layer 11 from sticking back to the wearer's skin after absorbing liquid.
[0045] When used in a better way, such as Figure 2 As shown, the absorbent layer 11, waterproof layer 12, impermeable edge 13, and skin-friendly layer 14 are all interconnected by a folded-overlay fixing structure. The folded-overlay fixing structure consists of the impermeable edge 13, skin-friendly layer 14, absorbent layer 11, and waterproof layer 12 stacked sequentially from top to bottom. The waterproof layer edge 120 is folded upwards, and then folded back towards the waterproof inner surface 121, allowing the waterproof outer surface 122 to contact the impermeable edge 13. A fixing member 101 passes sequentially through the waterproof outer surface 122, impermeable edge 13, skin-friendly layer 14, and absorbent layer 11 from the waterproof inner surface 121 side of the folded waterproof layer edge 120 to complete the fixing connection.
[0046] Specifically, the folded and wrapped fixing structure prevents pinholes from forming in the fixing member 101 when connecting the various layers, thus preventing liquid from seeping out through the fixing member 101 or pinholes due to capillary action. This reduces the possibility of the liquid sticking back to the wearer's skin and also prevents it from seeping into the pant body 2.
[0047] like Figure 2 As shown, the absorbent pad body 1 is connected to the pant body 2 by a connector 102 at one end of the anti-permeability edge 13 away from the absorbent pad body 1 using a connection method. This prevents the connector 102 from penetrating the waterproof layer 12, thus preventing liquid from seeping into the pant body 2 through the liquid retention space via pinholes or the connector 102.
[0048] In detail, the absorbent pad body 1 is fixed to the pant body 2 by the anti-seepage edge 13 and the connector 102, which increases the adhesion stability. At the same time, placing the connector 102 on the anti-seepage edge 13 away from the liquid retention space maintains the integrity of the liquid retention space and reduces the possibility of liquid seepage. It also prevents liquid from seeping from the absorbent layer 11 into the pant body 2 through the connector 102 due to capillary action. Furthermore, the anti-seepage edge 13 itself is made of waterproof material, which can effectively block liquid penetration.
[0049] In a preferred embodiment of this utility model, the anti-permeability edge 13 is provided on the lower side, left side and right side of the absorbent pad body 1, and the three anti-permeability edges 13 are integrally formed to prevent liquid from seeping into the pant body 2 from the connection of the anti-permeability edge 13.
[0050] Furthermore, maintaining the integrity of the liquid retention space reduces the possibility of liquid leakage, while gaps will exist between the interconnected anti-leakage edges 13 of different sheets; the increased splicing to reduce gaps will increase pinholes. Specifically, the higher the integrity of the anti-leakage edge 13, the fewer gaps at the junctions and the number of splicing pinholes can be, thus minimizing the chance of liquid leakage.
[0051] Preferably, the anti-seepage edge 13 is also provided on the upper side of the absorbent pad body 1 to prevent liquid or other substances from seeping upwards into the pant body 2.
[0052] like Figure 3 for Figure 1 The second embodiment of the present invention is shown in the AA direction. The waterproof layer 12 also has a folded portion 123, which is formed by folding the edge 120 of the waterproof layer from the outer waterproof surface 122 toward the inner waterproof surface 121.
[0053] like Figure 3 As shown, specifically, the absorbent pad body 1 is stacked from top to bottom in the following order: an impermeable edge 13, a skin-friendly layer 14, an absorbent layer 11, and a waterproof layer 12. The folded portion 123 is folded upwards. Furthermore, the folded portion 123 is folded back towards the waterproof inner surface 121. The fastener 101 passes sequentially from the surface 123A near the waterproof inner surface of the folded portion 123 through the interior 1230 of the folded portion, the surface 123B far from the waterproof inner surface of the folded portion 123, the impermeable edge 13, the skin-friendly layer 14, and the absorbent layer 11 for secure connection.
[0054] Preferably, the connection method can be a method of passing the connector 102 through the trouser body 2 and the anti-seepage edge 13, preferably by sewing.
[0055] Preferably, there can be multiple absorbent layers 11 to increase the effect of absorbing liquid.
[0056] like Figure 4 As shown in the cross-sectional schematic diagram of the third embodiment of this utility model, the anti-seepage edge 13 and the waterproof layer 12 are integrally formed. Specifically, the anti-seepage edge 13 can be an extension of the waterproof layer 12. By folding back the edge of the waterproof layer 12, the portion of the waterproof layer 12 that extends beyond the folded-back covering structure forms the anti-seepage edge 13.
[0057] like Figure 5 As shown in the schematic diagram of the fourth embodiment of this utility model, the absorbent pad body 1 is trapezoidal, with the upper side of the trapezoid being wider than the lower side, for receiving liquid.
[0058] Furthermore, the absorbent pad body 1 can extend from the front crotch of the pants body 2 to the crotch, or even to the back crotch, to increase the range of liquid absorption, so that the absorbent pad body 1 can properly absorb liquid in different postures of the wearer.
[0059] Preferably, the width of the absorbent pad body 1 is 10 to 20 centimeters.
[0060] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various changes and modifications without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
