Abstract: The valve consists of a number of functional features, including: a housing, a piston, and a piston control mechanism configured to enable a user to operate the valve to enable flow of a product through the valve. The housing is shown as having a substantially streamlined shape, with the thickness of the housing being smaller than the length and width dimensions, thereby providing a major surface that enables a user to grasp the housing between the thumb and the index finger of the hand. The housing contains a channel formed therein extending from a first end of the housing to a second end of the housing forming a fluid conduit that enables passage of the product through the fluid conduit. The flow of product is regulated by a piston located in the channel and movable from a first position in the channel where the piston blocks the fluid conduit to a second position in the channel where the piston fails to block the fluid conduit.

Abstract: This invention pertains to a device and the method of making same, which device functions both as a containment system for a product having either liquid, semi-liquid, solid or semi-solid characteristics, and as an applicator that can be used to deliver and apply the product to a surface in a convenient, economical and simple manner. The device includes an applicator pad that has a front surface that comes in contact with the desired surface to thereby apply the product thereto. A product impermeable backing layer is bonded to a rear surface of the applicator pad and a packet can be placed in position to release the product into the applicator pad through an aperture formed in the backing layer. A multi-purpose label is used to seal the packet in place, protects the user's hands, provides printed information to the user, provides the user with a device gripping surface and can also function to seal and/or reseal the applicator device.
