Abstract
Abstract A package is disclosed herein which may contain a fluid material which is capable of being discharged from the package by the application of manual pressure from a thumb and a forefinger to the package so as to cause the package to burst in a controlled fashion to discharge the fluid material contained within the package. The package comprises a chamber which receives the fluid material discharged from a containing chamber after the containing chamber is burst by manual pressure, so as to control the rate and manner of discharge of the fluid material from the package.

Claim 1
Independent Claim
161 words
A package for containing and discharging fluid materials, comprising: (a) a first chamber formed by two sheets of material sealed together about a perimeter of said first chamber, having a seal on one portion of said perimeter which will burst under manual pressure of 2.0 to 2.3 pounds per square inch applied to said first chamber and having a fluid material contained within said first chamber, which is discharged from said first chamber; and (b) a second chamber formed by two sheets of material sealed together about a perimeter of said second chamber, with said second chamber being adjacent to said first chamber so as to receive said fluid material as it is discharged through said seal of said first chamber, and having a seal on one portion of said perimeter of said second chamber which will burst at a pressure of 0.25 to 0.7 pounds per square inch, so as to cause said fluid to be discharged from the package.
