Problems solved by technology

However, in the case of forming the top sheet with a resin sheet, if the opening area ratio of the liquid absorption hole is reduced, the urine excreted on the top sheet is difficult to be attracted to the absorbent body, and residual liquid is likely to be generated on the surface.
On the contrary, if the opening area ratio of the liquid absorption hole is increased, since the absorbent body formed by the pulp layer and the water-absorbent polymer are directly opposite to each other under the top sheet, if the foot is stepped on, the urine retained in the pulp layer Exudation, the urine is easy to flow back to the surface of the top sheet through the liquid penetration holes, it is difficult to suppress dirt from adhering to the pet's feet

Embodiment Construction

[0033] figure 1 It is a perspective view showing the absorbent sheet 21 for pets according to the first embodiment of the present invention, figure 2 It is an exploded perspective view showing that each component of the absorbent sheet 21 for pets according to the first embodiment is separated, and FIG. 3 is figure 1 Sectional view of line III-III, Figure 4 yes figure 1 Sectional view of line IV-IV, Figure 5 It is an enlarged cross-sectional view showing part of a top sheet, a hydrophilic sheet, and a liquid-absorbing layer.

[0034] figure 1 The entirety of the shown absorbent sheet 21 for pets is rectangular. The absorbent sheet 21 for pets has a central region 22 with a length L1 and a width W1. The above-mentioned central region 22 has a liquid absorbing layer 25 (refer to figure 2 ) exists in the region. On the left and right outer sides of the central region 22 , side regions 23 on the long side with a width W2 are provided between the respective long sides 2...

Abstract

The present invention provides an absorbing sheet for pets scarcely attaching urine to foots of an urinated pet, having large water retaining amount even when the absorbing sheet is thin and capable of preventing diffusion of urine in the interior. A pulverized pulp layer 41 is provided under a surface sheet 33 formed of a resin film in which many liquid permeation holes 33a are formed in the absorbing sheet 21 for pets and a first highly water-absorbing material 42 is contained in the pulverized pulp layer 41 and a second highly water-absorbing material 43 having slower liquid absorbing rate than that of the first highly water-absorbing material is provided between the pulverized pulp layer 41 and the surface sheet 33. Since liquid absorbing rate of the second highly water-absorbing material 43 is slow, permeation of a liquid into the pulverized pulp layer 41 is not prevented and diffusion of urine can be suppressed by the first highly water-absorbing material 42 positioned in the pulverized pulp layer 41.

Description

technical field [0001] The present invention relates to an absorbent sheet for pets for absorbing urine excreted by pets such as dogs and cats. Background technique [0002] Absorbent sheets for pets are used to absorb urine excreted by pets such as dogs and cats kept at home. As the absorbent sheet for pets, there is an absorbent sheet described in Patent Document 1 or Patent Document 2. [0003] In the absorbent sheet for pets described in Patent Document 1, the absorbent body is composed of pulverized pulp and a water-absorbing polymer. The top sheet covering the surface side of the absorber is formed of a water-permeable nonwoven fabric, and a large number of openings are formed in the nonwoven fabric, and protrusions protruding toward the absorber are formed around the openings. In this absorbent sheet for pets, the above-mentioned protrusions are interposed to form a gap between the above-mentioned top sheet and the above-mentioned absorbent body, so as to isolate th...
