Description

  The present invention relates to a pet toilet used for the treatment of pets, particularly cat and dog excrement.

As a toilet for pets for processing the excrement of pets such as cats and dogs, the toilet body is divided into upper and lower parts by a spider that is a porous member, and an excrement treatment material (hereinafter, “ (Also referred to as “toilet sand”), and a urine absorbent material made of, for example, a water-absorbent resin, vegetable fiber, pulp, or the like is laid in the lower layer portion (lower portion) (for example, patent literature) 1-3). In these toilets for pets, the excrement disposal material laid in the upper layer allows the urine excreted by the pet to pass through quickly, and the passed urine is dropped to the lower layer through the permeation holes of the puppets. The urine absorbing material such as a urine absorbing mat disposed in the lower layer is actively absorbed. Although these excrement disposal materials have the feature of suppressing malodor by not disintegrating even if they absorb water to some extent, there are cases where it is not possible to clearly grasp the time for replacement because they do not disintegrate.
In addition, the use of excrement disposal materials and urine absorption materials complicates the structure and increases costs, and both excrement disposal materials and urine absorption materials must be replaced periodically, resulting in an increase in garbage. There is a problem that it ends up.

On the other hand, there is a cat litter that excretes the waste material made of sawdust from natural conifers by heating and compressing it into a pellet form and self-disintegrates by absorbing moisture (see Patent Document 4). With this technology, the litter falls down from the top of the bag by using it, so the replenishment time of litter can be clearly identified. Moreover, since the configuration is simple, the cost can be reduced. In addition, it has a feature not found in the above-mentioned technology that dust can be reduced by not using the urine absorbent. However, the toilet sand of this cat has a low amount of water absorption, and the degree of collapse after water absorption is low. Therefore, when there is a lot of urine, urine cannot be absorbed and urine leaks between the toilet sand. Then, the leaked urine bounces back to the bottom of the lower container and stains the surroundings, is unsanitary, the urine accumulates in the container under the urn, emits a foul odor, and the toilet sand that sucked urine does not collapse and the urn It is not satisfactory as a cat litter because it stagnates on the top of the bed and the collapsed toilet sand stays on top of the cocoon and emits a foul odor.

  Therefore, the object of the present invention is to self-collapse by water absorption and fall from the spider slag and decrease so that the replenishment period can be clearly grasped, and the vertical cross-sectional shape (hereinafter referred to simply as “cross-sectional shape”) The purpose of the present invention is to provide a pet toilet that does not generate bad odor by improving the above-mentioned problem of staying on collapsed toilet sand and urine staying on the tray. And

  As a result of the study of the above problems by the present inventors, it was found that the collapsed toilet sand does not stay on the reeds by forming the cross-sectional shape of the ribs of the reeds so that the width on the upper surface side is narrower than the width on the lower surface side. It was. In addition, the opening of the cocoon child becomes a funnel shape, and the toilet sand that has fallen from the cocoon child gathers and collects in one place. Moreover, even if urine cannot be absorbed when there is much urine, even if urine leaks from between toilet sand, urine also falls along the funnel and accumulates in one place. As a result, since urine is absorbed into the toilet sand, the urine does not accumulate on the tray, the generation of bad odor is suppressed, and it is found that the pet toilet is satisfactory and the above object is achieved.

  That is, the present invention is a pet toilet having a toilet body that is divided into upper and lower parts by a scissors, laying a pet excrement disposal material that self-disintegrates by absorbing water in an upper layer part, and having a tray in a lower layer part, A pet toilet having a cross-sectional shape of the rib of the cocoon child is formed such that the width on the upper surface side is narrower than the width on the lower surface side.
