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 may comprise a second chamber which receives the fluid material discharged from the first chamber after the first chamber is burst by manual pressure so as to further control the rate and manner of discharge of the fluid material from the package.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
95 words
A package for containing and discharging fluid materials, comprising two sheets of materials sealed together about a perimeter of said sheets so as to form a container in which a fluid material may be contained, wherein a portion of a seal so formed is not capable of bursting under manual pressure and the remaining portion of said seal is capable of bursting under manual pressure applied to said container, and wherein said seal which is capable of bursting under manual pressure is formed by applying pressure to said sheets by a heated, corrugated forming means.
Claim 2
Dependent Claim
95 words
A package for containing and discharging fluid materials, comprising two sheets of materials sealed together about a perimeter of said sheets so as to form a container in which a fluid material may be contained, wherein a portion of a seal so formed is not capable of bursting under manual pressure and the remaining portion of said seal is capable of bursting under manual pressure applied to said container, and wherein said seal which is capable of bursting under manual pressure is formed by applying pressure to said sheets by a heated, corrugated forming means.
Claim 3
Dependent Claim
88 words
A package for containing and discharging fluid materials, comprising: (a) a first chamber which will burst under manual pressure applied to said first chamber and a fluid material contained within said first chamber so as to discharge said fluid material; and (b) a second chamber contiguous to said first chamber which will receive said fluid material as it is discharged from said first chamber and which will burst under lesser pressure applied to said second chamber, and said fluid so as to discharge said fluid from said package.
Claim 4
Dependent Claim
88 words
A package for containing and discharging fluid materials, comprising: (a) a first chamber which will burst under manual pressure applied to said first chamber and a fluid material contained within said first chamber so as to discharge said fluid material; and (b) a second chamber contiguous to said first chamber which will receive said fluid material as it is discharged from said first chamber and which will burst under lesser pressure applied to said second chamber, and said fluid so as to discharge said fluid from said package.
Claim 5
Dependent Claim
152 words
A package for containing and discharging fluid materials, comprising: (a) a first chamber formed by two sheets of material sealed together about the perimeter of said first chamber, having a seal on one portion of said perimeter which will burst under manual pressure applied to said first chamber and to a fluid material contained within said first chamber so as to discharge said fluid material from said first chamber; (b) a second chamber formed by two sheets of material sealed together about the perimeter of said second chamber, with said second chamber being contiguous to said first chamber so as to receive said fluid material as it is discharged from said first chamber, and having a seal on one portion of said perimeter of said second chamber which will burst under less pressure than said seal of said first chamber so as to cause said fluid to be discharged from said package.
Claim 6
Dependent Claim
152 words
A package for containing and discharging fluid materials, comprising: (a) a first chamber formed by two sheets of material sealed together about the perimeter of said first chamber, having a seal on one portion of said perimeter which will burst under manual pressure applied to said first chamber and to a fluid material contained within said first chamber so as to discharge said fluid material from said first chamber; (b) a second chamber formed by two sheets of material sealed together about the perimeter of said second chamber, with said second chamber being contiguous to said first chamber so as to receive said fluid material as it is discharged from said first chamber, and having a seal on one portion of said perimeter of said second chamber which will burst under less pressure than said seal of said first chamber so as to cause said fluid to be discharged from said package.
Claim 7
Dependent Claim
69 words
A package for containing and discharging fluid materials as described in claim 3, wherein said seal on one portion of said perimeter of said first chamber which will burst under manual pressure is formed by applying a heated, corrugated forming means to said sheets under pressure, so as to form a seal which will peel apart in a controlled fashion as said fluid material under pressure enters said seal.
Claim 8
Dependent Claim
120 words
A package for containing and discharging fluid materials, comprising: (a) a first chamber having a seal on one portion of said perimeter which will burst under manual pressure applied to said first chamber and to a fluid material contained within said first chamber so as to discharge said fluid material from said first chamber; (b) a second chamber which is contiguous to said first chamber so as to receive said fluid material as it is discharged from said first chamber, and having a seal on one portion of a perimeter of said second chamber which will burst under less pressure than said seal of said first chamber so as to cause said fluid material to be discharged from said package.
Claim 9
Dependent Claim
120 words
A package for containing and discharging fluid materials, comprising: (a) a first chamber having a seal on one portion of said perimeter which will burst under manual pressure applied to said first chamber and to a fluid material contained within said first chamber so as to discharge said fluid material from said first chamber; (b) a second chamber which is contiguous to said first chamber so as to receive said fluid material as it is discharged from said first chamber, and having a seal on one portion of a perimeter of said second chamber which will burst under less pressure than said seal of said first chamber so as to cause said fluid material to be discharged from said package.
Claim 10
Dependent Claim
69 words
A package for containing and discharging fluid materials as described in claim 5, wherein said seal on one portion of said perimeter of said first chamber which will burst under manual pressure is formed by applying a heated, corrugated forming means to said sheets under pressure, so as to form a seal which will peel apart in a controlled fashion as said fluid material under pressure enters said seal.
