Abstract
Description
[Technical Field]
[0001] The present invention relates to the technical field of urine absorption pads for pets, and more particularly to disposable water-absorbent urine absorption pads. [Background technology]
[0002] Currently, all disposable pet urine pads on the market are single-sided absorbent pads (with a waterproof film underneath to prevent leakage) with a multi-layered internal structure, which requires a large amount of material to produce and makes them expensive. Summary of the Invention
[0003] According to an embodiment of the present invention, a pair of hydrophilic surfaces arranged opposite each other; A disposable absorbent urine pad is provided, which includes a pair of hydrophilic surface layers and an absorbent layer disposed between the pair of hydrophilic surface layers for absorbing and storing moisture.
[0004] Furthermore, the material of the hydrophilic surface layer is moisture-resistant paper.
[0005] Furthermore, the material of the hydrophilic surface layer is a nonwoven fabric.
[0006] Furthermore, the water absorption layer a polymeric water-absorbent resin disposed between a pair of hydrophilic surface layers; and an absorbent wood pulp layer disposed between a pair of hydrophilic surface layers and encasing a polymeric absorbent resin. [Effects of the Invention]
[0007] The disposable absorbent urine pad according to the embodiment of the present invention has the beneficial effects of being simple in structure, requiring relatively few materials, having relatively low production costs, being absorbent on both sides, and being easy to use.
[0008] It is to be understood that both the foregoing general description and the following detailed description are exemplary and are intended to provide further explanation of the claimed technology. [Brief explanation of the drawings]
[0009] [Figure 1] 1 is a diagram showing the overall structure of a disposable absorbent urine pad according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0010] The present invention will be further explained by describing in detail the preferred embodiments of the present invention with reference to the drawings below.
[0011] First, referring to FIG. 1, a disposable absorbent urine pad according to an embodiment of the present invention will be described, which is used for pets and has a very wide range of application scenarios.
[0012] As shown in FIG. 1, the disposable absorbent urine pad according to the embodiment of the present invention comprises a pair of hydrophilic surface layer 1 and a water-absorbing layer.
[0013] Specifically, as shown in Figure 1, a pair of hydrophilic surface layers 1 are arranged opposite each other, and the material of the hydrophilic surface layers 1 is moisture-resistant paper (biodegradable) or nonwoven fabric, which has hydrophilic properties and therefore does not inhibit water absorption, allowing water to quickly reach the internal water-absorbing layer.
[0014] Specifically, as shown in FIG. 1, the water-absorbing layer is disposed between a pair of hydrophilic surface layers 1 and serves to absorb and store moisture. The water-absorbing layer includes a polymeric water-absorbent resin 22 and water-absorbent wood pulp 21. The polymeric water-absorbent resin 22 is disposed between the pair of hydrophilic surface layers 1. The polymeric water-absorbent resin 22 is a new type of functional polymer material that has high water-absorbing ability, absorbing hundreds to thousands of times its own weight in water, and has excellent water-retention properties. Once it absorbs water and swells into a hydrogel, it is difficult for the water to separate even under pressure. The water-absorbent wood pulp 21 is disposed between the pair of hydrophilic surface layers 1 and encases the polymeric water-absorbent resin 22. The wood pulp fiber structure has numerous irregular gaps. These natural gaps are processed to be superhydrophilic, allowing it to store a large amount of moisture. Due to the interaction between the polymer absorbent resin 22 and the absorbent wood pulp 21, the polymer absorbent resin 22 hardens as it absorbs water and becomes a hydrogel, and begins to form a ball-like shape (commonly known as caking). On the other hand, the addition of the absorbent wood pulp 21 helps keep the urine absorption pad as flat and soft as possible, better retains moisture, and prevents the polymer from slipping and forming a pile.
[0015] The above describes a disposable absorbent urine pad according to an embodiment of the present invention, with reference to FIG. 1, which has the beneficial effects of being simple in structure, requiring relatively few materials, having relatively low production costs, being absorbent on both sides, and being easy to use.
[0016] It should be noted that, as used herein, the terms "comprise," "contain," or any variation thereof, are intended to encompass a non-exclusive inclusion, such that a process, method, article, or apparatus that includes a set of elements includes not only those elements but also other elements not expressly listed or that are inherent to such process, method, article, or apparatus. Unless further limited, an element qualified by the phrase "comprises" does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0017] Although the contents of the present invention have been described in detail by the above preferred embodiments, it should be appreciated that the above description should not be considered as limiting the present invention. Various modifications and alternatives to the present invention will become apparent to those skilled in the art after reading the above contents. Therefore, the protection scope of the present invention should be limited by the appended claims.
