Abstract

The present invention provides a refuse receptacle that is very effective at eliminating odors. This refuse receptacle is characterized by having a refuse receptacle body that has an inlet for inserting refuse, and a cover that closes the inlet of the refuse receptacle body so as to be freely opened and closed, and being configured such that the refuse receptacle body and/or the cover contains a synthetic resin and a solid that is contained in the synthetic resin and is formed by removing at least some of the essential oil and moisture from a woody raw material containing Sakhalin fir. Thus, the refuse receptacle stably maintains an excellent odor eliminating effect over a long period of time.

Description

ゴミ箱及びその製造方法Trash can and its manufacturing method
　本発明は、ゴミ箱及びその製造方法に関する。 The present invention relates to a trash can and a method for manufacturing the same.
　従来から家庭において、台所などで排出される生ゴミ、使用済みのオムツ、ペット用シーツなどのゴミは、ゴミ収集日までの間、ゴミ箱にて保管、蓄積される。生ゴミ、使用済みのオムツ、ペット用シーツなどのゴミは、水分を含んでいることから、特に夏場においては微生物が繁殖することによって臭いを発することがある。 Traditionally, at home, garbage such as kitchen garbage, used diapers, and pet sheets are stored and accumulated in a garbage box until the garbage collection date. Garbage such as kitchen waste, used diapers, and pet sheets contains water, and therefore, especially in the summer, the growth of microorganisms may cause an odor.
　そこで、特許文献１には、消臭ユニットは、収納容器を有してこの収納容器内に活性炭を収納した消臭袋を入れ、前記収納容器の開口に多数の通気口を形成した蓋体を被せると共に、収納容器の背面に取付片を設け、使用時に消臭ユニットを前記収納容器の背面に設けた取付片を介してゴミ箱の上蓋内側に配置可能とした消臭ゴミ箱が提案されている。 Therefore, in Patent Document 1, the deodorizing unit has a storage container, and a deodorizing bag containing activated charcoal is put in the storage container, and a lid having a large number of vents formed in the openings of the storage container is provided. A deodorant trash can has been proposed in which a mounting piece is provided on the back surface of the storage container and the deodorizing unit can be arranged inside the upper lid of the trash can via the mounting piece provided on the back surface of the storage container.
