Abstract: The sealing arrangement for joining a valve mounting cup to an aerosol container includes provision of a valve mounting cup having a bent over flange portion of sufficient extent to permit clinching as well as crimping of the valve mounting cup to the aerosol container. The bent over flange portion drapes a predetermined amount alongside the bead or curl of the container to permit a clinching operation that anchors the mounting cup to the container. A sequential crimping operation further secures the valve mounting cup to the container bead and effectively squeezes a gasket provided between the mounting cup and container bead to provide a leak tight seal. Any striations present in the container bead are effectively plugged by the gasket due to the tight envelopment of the bent over flange around the container bead.

Abstract: A method, composition and containerized product for use in preventing the disease of mastitis in dairy cows and other animals. The invention employs a homogeneous disinfectant composition in the form of an aerosol spray which applies disinfectant to the teat while at the same time chilling the teat, particularly at the lower end where the teat sphincter muscle is located. Use of the present disinfectant composition, which contains an aerosol propellant such as dimethyl ether, results in chilling temperatures of about 25.degree. to 35.degree. F. being attained on the exterior surface and orifice end of the teat. By such treatment, the teat sphincter is caused to contract and close the teat orifice, thus reducing the incidence of infection.
