Description

This disclosure relates to absorbent articles for pets. Patent Document 1 describes an absorbent article for pets comprising a ventral region, a dorsal region, an intermediate region located between the ventral and dorsal regions, a permeable inner layer sheet, an impermeable outer layer sheet, and an absorbent core located between the inner and outer layers. The absorbent article is provided with fastening tabs extending laterally outward from both side edges of the ventral region. When the absorbent article is worn, the first fastening elements of a pair of fastening tabs engage with the second fastening elements of a receiving portion located on the outer surface of the dorsal region. The dorsal region of the absorbent article has dorsal side flaps extending outward from both side edges of the inner layer sheet. Japanese Patent Publication No. 2015-228857 This is a plan view of an absorbent pet article according to one embodiment, as seen from the skin-facing side.This is a plan view of an absorbent pet product, seen from the non-skin side.This is a cross-sectional view of an absorbent article for pets along the line A-A in Figure 1.(a) is a diagram illustrating the procedure for attaching an absorbent pet product to a pet, and (b) is a diagram showing the pet with the absorbent pet product attached. Embodiments of this disclosure will be described in detail below with reference to the drawings. In the description of the drawings, identical elements are denoted by the same reference numerals, and redundant descriptions are omitted. The drawings may be simplified or exaggerated in some parts for ease of understanding, and dimensional ratios are not limited to those shown in the drawings. Figure 1 is a plan view of an absorbent pet article 1 (hereinafter simply referred to as "absorbent article 1") according to one embodiment, viewed from the skin side Z1. Figure 2 is a plan view of the absorbent article 1 viewed from the non-skin side Z2. Figure 3 is a cross-sectional view of the absorbent article 1 along the line A-A shown in Figure 1. Figures 1 and 2 show the absorbent article 1 in an unfolded state, stretched to a state where no wrinkles are formed. In the following description, unless otherwise specified, the positional relationships will be described in the unfolded state. The absorbent article 1 shown in Figures 1 to 3 is a disposable pet diaper that absorbs pet urine. The skin-facing side Z1 is the side of the absorbent item 1 that faces the pet's skin when worn, and the non-skin-facing side Z2 is the side of the absorbent item 1 that faces away from the pet's skin when worn. In the following explanation, the person who attaches the absorbent item 1 to the pet is referred to as the "user." Typically, the user is the pet's owner. In this specification, "pet" broadly encompasses vertebrates and invertebrates, typically including companion animals such as dogs, cats, rabbits, and hamsters. As shown in Figure 1, the absorbent article 1 extends in a width direction X, which is aligned with the circumference of the pet's body, and in a longitudinal direction Y, which connects the ventral to the dorsal side of the pet. The width direction X and the longitudinal direction Y are perpendicular to each other. The thickness direction Z is perpendicular to the width direction X and the longitudinal direction Y, and includes a skin-facing side Z1 that faces the pet's skin when worn, and a non-skin-facing side Z2 that faces away from the pet's skin when worn. As shown in Figures 4(a) and (b), the absorbent article 1 is fitted to cover the pet from the ventral side, through the crotch, to the dorsal side. The absorbent article 1 has a main body 2 and a pair of fastening tabs 90. The main body 2 extends in the width direction X and the longitudinal direction Y. The main body 2 has a ventral region 51 that covers the pet's abdomen when worn, a dorsal region 52 that covers the pet's back when worn, and a crotch region 53 positioned between the ventral region 51 and the dorsal region 52 in the longitudinal direction Y. For example, the ventral region 51, dorsal region 52, and crotch region 53 correspond to three equal parts of the main body 2 divided in the longitudinal direction Y. In the following description, the direction from the dorsal region 52 towards the ventral region 51 may be referred to as "ventral," and the direction from the ventral region 51 towards the dorsal region 52 may be referred to as "dorsal." As shown in Figures 1 to 3, the main body 2 includes a surface sheet 10, a back sheet 20, and an absorbent material 30. The surface sheet 10 forms the surface of the main body 2 that comes into contact with the pet and is positioned on the skin side Z1. The surface sheet 10 is permeable to water, allowing the pet's urine to pass through to the absorbent material 30. The backing sheet 20 constitutes the outer surface of the main body 2 when worn, and is positioned on the non-skin side Z2. The backing sheet
