Abstract
Abstract A contraceptive containing device including a contraceptive gel having a pH of less than 3.0; an elongated casing containing the gel and having an insertion end extending beyond the gel; and a hygenically sealed pouch enclosing the casing. The seal at one end of the pouch overlaps the insertion end of the casing to secure the casing to the pouch and close the insertion end of the casing. The casing is weakened in a region near where it is secured to the pouch for tearing when the pouch is opened to expose the casing and the casing is pulled with respect to the overlapping end of the pouch so as to provide a shearing stress in the casing near the insertion end, for thereby separating the casing from the pouch.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
207 words
A contraceptive containing device, comprising a contraceptive gel having a pH less than 3.0; an elongated casing containing the gel, and having an insertion end extending beyond the gel wherein said insertion end has an outer portion, and an inner portion between said outer portion and said gel; and a hygenically sealed pouch enclosing the casing and having a seal at one end of the pouch which overlaps said outer portion of the insertion end of the casing to secure the casing to the pouch and close the insertion end of the casing; wherein said casing has a weakened region in said inner portion of the insertion end, whereby the casing can be exposed by the application of shear stress at a region in at least one side of the pouch excluding the pouch portion which overlaps the insertion end of the casing to allow removal of a portion of the pouch, and wherein said casing can be removed from the remaining portion of the pouch by pulling on the end of the casing remote from the insertion end to provide a shearing stress in the casing near the insertion end of the pouch for causing said casing to detach from said remaining portion of the pouch.
Claim 2
Dependent Claim
207 words
A contraceptive containing device, comprising a contraceptive gel having a pH less than 3.0; an elongated casing containing the gel, and having an insertion end extending beyond the gel wherein said insertion end has an outer portion, and an inner portion between said outer portion and said gel; and a hygenically sealed pouch enclosing the casing and having a seal at one end of the pouch which overlaps said outer portion of the insertion end of the casing to secure the casing to the pouch and close the insertion end of the casing; wherein said casing has a weakened region in said inner portion of the insertion end, whereby the casing can be exposed by the application of shear stress at a region in at least one side of the pouch excluding the pouch portion which overlaps the insertion end of the casing to allow removal of a portion of the pouch, and wherein said casing can be removed from the remaining portion of the pouch by pulling on the end of the casing remote from the insertion end to provide a shearing stress in the casing near the insertion end of the pouch for causing said casing to detach from said remaining portion of the pouch.
Claim 3
Dependent Claim
14 words
A contraceptive device according to claim 1, wherein the pouch consists of sheet-like surfaces.
Claim 4
Dependent Claim
17 words
A contraceptive device according to claim 1, wherein the pouch consists of a single sheet of material.
Claim 5
Dependent Claim
48 words
A contraceptive device according to claim 1, further comprising closure means for closing the casing between the weakened region and by gel, wherein the closure means is adapted for opening to release the gel when the casing is squeezed after the casing has been separated from the pouch.
Claim 6
Dependent Claim
29 words
A contraceptive device according to claim 1 wherein the insertion end of the casing is adapted for opening to enable release of the gel when the casing is separated.
