Patent number: 10517264Abstract: Provided is an animal litter that is capable of sufficiently exerting an effect of perfume-containing microcapsules over a long period of time, and a method for manufacturing the same. The animal litter includes a plurality of grains, wherein each of these grains includes a granular base material and a plurality of microcapsules adhering to the outer surface of the base material, the base material includes a low-absorbent material having an initial absorption rate of 10% or less, and the individual microcapsules are impact-breakable microcapsules including a perfume.Type: GrantFiled: December 9, 2014Date of Patent: December 31, 2019Assignee: UNICHARM CORPORATIONInventor: Tatsuya Sogou

Patent number: 10091969Abstract: Provided is toilet sand for animals which retains satisfactory liquid permeability and can absorb, with the lapse of time, any liquid remaining on the surface and which can be prevented from generating dust when in use, etc. The toilet sand for animals comprises a plurality of granules, each of the granules comprising: a core configured of an inorganic porous material and a binder with which particles of the inorganic porous material are integrally affixed; and a water-blocking coating layer formed on the surface of the core and configured of a water-blocking material which has water-absorbing properties and which, in the state of having absorbed water, has viscosity. Preferably, the water-blocking material is configured of one or more substances selected from the group consisting of ethylene/vinyl acetate copolymers, polyvinyl alcohol, and starch.Type: GrantFiled: November 21, 2014Date of Patent: October 9, 2018Assignee: UNICHARM CORPORATIONInventor: Tatsuya Sogou

Patent number: 10076098Abstract: An animal litter box has a transverse direction, a longitudinal direction and a vertical direction and includes a lower container having an opening at an upper end thereof and allocated on the lower side, an upper side cover allocated above the lower container and a liquid passable litter tray interposed between the upper side cover and the lower container and cooperating with the lower container to close the opening. The lower container has an excrement tray provided so as to be manually movable in the longitudinal direction between a put-in position at which the excrement tray is set within the receiving space below the liquid passable litter tray and a drawn out position outside the receiving space and an end opening through which the excrement tray is put into or drawn out from the receiving space.Type: GrantFiled: May 17, 2012Date of Patent: September 18, 2018Assignee: UNICHARM CORPORATIONInventors: Takayuki Matsuo, Tatsuya Sogou

Patent number: 9516856Abstract: An animal litter sand that effectively prevents scattering of particles without increasing the weight or density of the litter sand. The animal litter sand is prepared by forming particles by a step that adds water and mixes together at least a particulate substrate from an inorganic material, a hydraulic solidification material, and a water-soluble thickener.Type: GrantFiled: March 21, 2013Date of Patent: December 13, 2016Assignee: Unicharm CorporationInventors: Tatsuya Sogou, Takayuki Matsuo

Publication number: 20150351362Abstract: To provide animal toilet sand that allows easy recognition of an area where urine has been absorbed, easy observation of the color of urine, and suppression of odor of excreted urine. An animal toilet sand is composed of a plurality of particulates having a water absorbing property, wherein the particulates include: color change particles that are configured to include pulp and to change color upon absorbing moisture; and white particles that have a core portion which is configured to include pulp and a covering layer which is configured to include pulp, highly absorbent resin and fragrance, and to cover the core portion, the white particles not changing color upon absorbing moisture, and the color change particles are included at a higher ratio by weight than the white particles.Type: ApplicationFiled: June 17, 2013Publication date: December 10, 2015Inventors: Kenji HIROSHIMA, Tatsuya SOGOU, Tomoko HIRAO, Shinya KANEKO, Hidekazu YAMADA, Takahiro OTOMO
