Patent ID: 10183792

Abstract:
The invention provides a container (10) for the packaging of a fluent product (P) which off-gases, the container comprising: a container body (11) for receiving and storing product and a removable lid (12) for closing the container body; in which the lid is provided with a venting assembly (20, 23a, 23b, 24) extending into the container body; in which the venting assembly has a closed position which is effective to close the container body and a venting position permitting the venting of gas from the container body; whereby, when the container body is partially filled with a fluent product which off-gases, the venting assembly moves to the venting position in response to excessive pressure from accumulated gas, and reverts to the closed position upon release of the excessive pressure, thus effecting periodic venting of the container body; and whereby the spatial arrangement of the venting assembly within the container body provides for venting of the container body independently of the orientation of the container, while retaining the product within the container body. The container is especially suitable for the packaging of viscous or semisolid products which incorporate an oxidizing agent, such as creams or gels for the bleaching or coloring of hair.
