Abstract
Abstract A dispenser for dispensing fluids having a self-sealing applicator head which has a flexible arcuate surface in which one or more angular slits are cut; the angular slits make an acute angle of from about 25° to about 70° with the perpendicular to the tangent of the arcuate surface at the point where the slit meets the arcuate surface.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
A dispenser for dispensing fluid comprising a container portion for storing said fluid and a self-sealing applicator portion for applying said fluid to a surface; said applicator portion being positioned so as to be in communication with fluid maintained in said container portion; said applicator portion having an arcuate surface and being adapted to accommodate the armpit of an average individual; said applicator portion also being constructed of flexible material and provided with at least one angular slit cut through its surface whereby the interior of said container portion is made to communicate with the atmosphere when pressure is applied to said fluid; said angular slit being such that it makes an acute angle of from about 25° to about 70° with the perpendicular to the tangent of the arcuate surface of said applicator portion at the point where said slit meets said arcuate surface; said container portion being adapted to apply pressure to the fluid contents of said container portion whereby the fluid contents of said container portion may be expressed tnrough said angular slits when pressure is applied to said fluid contents and whereby said angular slits are self-sealed when the pressure on said fluid contents is relieved.
Claim 2
Dependent Claim
200 words
A dispenser for dispensing fluid comprising a container portion for storing said fluid and a self-sealing applicator portion for applying said fluid to a surface; said applicator portion being positioned so as to be in communication with fluid maintained in said container portion; said applicator portion having an arcuate surface and being adapted to accommodate the armpit of an average individual; said applicator portion also being constructed of flexible material and provided with at least one angular slit cut through its surface whereby the interior of said container portion is made to communicate with the atmosphere when pressure is applied to said fluid; said angular slit being such that it makes an acute angle of from about 25° to about 70° with the perpendicular to the tangent of the arcuate surface of said applicator portion at the point where said slit meets said arcuate surface; said container portion being adapted to apply pressure to the fluid contents of said container portion whereby the fluid contents of said container portion may be expressed tnrough said angular slits when pressure is applied to said fluid contents and whereby said angular slits are self-sealed when the pressure on said fluid contents is relieved.
Claim 3
Dependent Claim
28 words
A dispenser according to claim 1 in which said arcuate surface has a radius of curvature in the range of from 3/4 inch to about 2 1/2 inches.
Claim 4
Dependent Claim
29 words
or 2 3. A dispenser according to claim 1/in which said applicator portion has an overall diameter in the range of from about 1 inch to about 3 inches.
Claim 5
Dependent Claim
50 words
2, or 3 4. A dispenser according to claim 1,An which at least two of said angular slits are cut through the surface of said applicator portions; said slits forming segments of a circle having a diameter in the range of from about 1/4 inch to about 1 1/2 incnes.
Claim 6
Dependent Claim
38 words
any one of to 4 5. A dispenser according to/claimsl/in which said container portion is also made of flexible material whereby pressure may be applied to the fluid contents of said container portion by squeezing said container portion.
Claim 7
Dependent Claim
55 words
A dispenser according to claim 5 including shielding means being relatively rigid whereby the inadvertent application of pressure to said flexible container portion and the inadvertent expression of fluid from said container portion is avoided; said shielding means being provided at specified places thereof with means for selectively applying pressure to said flexible container portion.
Claim 8
Dependent Claim
52 words
A dispenser according to claim 6 in which said means for selectively applying pressure to said flexible container portion comprises a single opening or a cut through the said shielding means; said opening being of sufficient dimension so that average fingers may pass tnerethrough to engage and squeeze said flexible container portion.
Claim 9
Dependent Claim
42 words
A dispenser according to claim 6 in which said means for selectively applying pressure to said flexible container portion comprises a pair of openings being of sufficient dimension so that average fingers may pass therethrough to engage and squeeze said flexible container.
Claim 10
Dependent Claim
50 words
any one of 9. A dispenser accoroing to/claims 1 to 8 including a self-standing base, said self-standing base being adapted to engage and support said dispenser in the region of its applicator portion so that saio dispenser is supported in a standing position with theslit(s)in said applicator portion facing downwardly.
