Abstract: A method and device for disinfecting an item with a disinfecting agent and a suitable neutralizer to neutralize the agent. The item is placed in a container with the agent. A neutralizer is placed in the container in a receptacle which hinders the contact between the agent and the neutralizer so that the items can be disinfected. A device includes a container and a receptacle which regulates the renewal of the agent in contact with the neutralizer.

Abstract: An elastic valve for controlling a fluid flow including a valve body with a perforation. The body is made of an elastic material, such as silicon or a similar substance. The perforation normally remains closed but can be opened when the differential pressure reaches a pre-determined value. The body can be provided with a flange which facilitates the handling and placement of the valve in the corresponding valve socket. The valve is especially useful for contact lens containers where the valve releases gasses from the container which are created during the disinfecting process.
