Abstract:
This invention relates to a device for providing a dose of a liquid or solid to a larger container. More particularly, this invention relates to a dispensing device for providing a dose of substances, such as solid or liquid detergents or bleaches to a wash tub. This is accomplished by the structure of the doser device which provides for an increase and decrease in the volume of the doser during use. In a preferred embodiment, the structure to increase and decrease the volume of the dispenser is one or more bellows which are a part of the surface of the doser.
Abstract:
A multichamber container must have certain characteristics in order to uniformly dispense the contents of each chamber from the container. The outer wall of the container and the inner divider web walls must have certain characteristics. The inner divider web walls must be highly flexible while the outer container wall must be less flexible. The Deflective Force for the outer wall must be greater than the Deflective Force for the web walls. In addition, to alleviate the problem of suckback of air into the container chambers, the outer wall should exhibit a specific Retention Index. This is a measure of the outer wall to remain deflected after the removal of the deflecting force. The inner divider web wall will have a lower Retention Index than the outer wall. By the proper selection of outer wall and web walls, there can be uniform dispensing from the dispenser.

Abstract:
Tubular containers can be produced by injection stretch blow molding processes. Such processes comprise the biaxial stretching of the preform as the preform is being converted into the tubular container. The preform will be stretched longitudinally by means of a stretch rod and laterally by means of the pressure of the blowing gas. The tubular containers produced by these processes will have burst strengths three to five times that of other tubular containers and can be produced in a thin wall collapsible form. Further, the tubular containers can be single chamber containers or multi-chamber containers.
