Abstract
An apparatus and package for liquid or granular materials includes two pivotally mounted dispensing blocks associated with a dispensing arm, whereby upon application of an actuating force to the dispensing arm, a resilient tube of the package is pinched shut by one dispensing block and the other dispensing block opens a slit diaphragm valve disposed within the resilient tube.
Claims12
Apparatus for dispensing liquid or granular materials, for use with a package which contains liquid or granular material and has a resilient tube associated with said package, comprising:
- a housing, said housing including means for supporting said package;
- a backup block, having a compression surface thereon, associated with said housing;
- a dispensing arm having a first end portion pivotally associated with said housing and having a second, free end portion;
- a first dispensing block associated with said dispensing arm, said first dispensing block being disposed adjacent the compression surface of said backup block;
- and
- a second dispensing block pivotally and yieldably mounted (associated) with respect to said dispensing arm, said second dispensing block disposed beneath, and spaced from, the first dispensing block whereby, upon an actuating force being imposed upon the free end portion of said dispensing arm, the first dispensing block contacts the resilient tube at a first predetermined impact point to compress the resilient tube against the compression surface of the backup block, and the second dispensing block contacts the resilient tube at a second predetermined impact point spaced from, and below, said first impact point, to apply a force to the resilient tube.
