Abstract
Abstract A flexible cap is designed to make a tight seal with a bottle or the like. The cap may be either a snap-on or a screw-on cap. There are two annular tonguelets which extend down from the top of the cap, and preferably there is also an annular tongue. The tongue and tonguelets are concentric. The tonguelets are brought into pressure contact with the top surface of the wall of the bottle when the cap is in place on the bottle, and the tongue makes pressure contact with the inner top edge and/or the inner surface of the wall of the bottle. The tonguelets meet the top of the wall at an angle and when they are in pressure contact with this wall they are flexed. When both tonguelets are inclined inward, the outer tonguelet makes a greater angle with the skirt of the cap than the inner tonguelet so that when the tonguelets are flexed inward against the top of a bottle there is more room for the outer tonguelet to flex inward than if both tonguelets were parallel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
83 words
A flexible closure cap for a container which comprises a skirt to contact with the surface of the wall of the container and an annular tonguelet which depends from the top of the cap and is inclined outwardly, the end of which tonguelet when the tonguelet is flexed upwardly is adapted to extend beyond the outer surface of the container wall, and the inner surface of said skirt is indented near its top to accommodate the end of the tonguelet when so flexed.
Claim 2
Dependent Claim
83 words
A flexible closure cap for a container which comprises a skirt to contact with the surface of the wall of the container and an annular tonguelet which depends from the top of the cap and is inclined outwardly, the end of which tonguelet when the tonguelet is flexed upwardly is adapted to extend beyond the outer surface of the container wall, and the inner surface of said skirt is indented near its top to accommodate the end of the tonguelet when so flexed.
Claim 3
Dependent Claim
169 words
The combination of a container with an opening at the top and a closure cap of flexible material with a skirt which fits over the opening, means on the inner surface of the skirt engaged with means on the outer surface of the wall of the container near the top thereof, and upper and lower angular concentric tonguelets angling down from the top of the cap in substantially the same direction, to substantially the same level, into pressure contact with the top surface of the wall of the container, there being more space between the tonguelets at their tops than at their bottoms, said tonguelets being spaced from each other at their bottoms and the lower tonguelet making a smaller angle with the top surface of the wall of the container than the upper tonguelet whereby when the tonguelets are flexed by contact with the top surface of the wall of the container there is more room for the lower tonguelet to flex than if the tonguelets were parallel.
Claim 4
Dependent Claim
169 words
The combination of a container with an opening at the top and a closure cap of flexible material with a skirt which fits over the opening, means on the inner surface of the skirt engaged with means on the outer surface of the wall of the container near the top thereof, and upper and lower angular concentric tonguelets angling down from the top of the cap in substantially the same direction, to substantially the same level, into pressure contact with the top surface of the wall of the container, there being more space between the tonguelets at their tops than at their bottoms, said tonguelets being spaced from each other at their bottoms and the lower tonguelet making a smaller angle with the top surface of the wall of the container than the upper tonguelet whereby when the tonguelets are flexed by contact with the top surface of the wall of the container there is more room for the lower tonguelet to flex than if the tonguelets were parallel.
Claim 5
Dependent Claim
11 words
The combination of claim 2 in which the tonguelets angle inwardly.
Claim 6
Dependent Claim
103 words
A closure cap for a container, which cap is composed of flexible material and comprises a skirt adapted to fit over the open top of the container, an annular tongue which depends from the cap inside of the skirt and is adapted to extend into the top of the container and make sealing contact with the container, and a tonguelet which extends down from the cap between the skirt and the tongue, adjacent the tongue, there being an annular indentation that spaces the bases of the tongue and tonguelet and narrows the base of the tongue and tonguelet and gives them greater flexibility.
Claim 7
Dependent Claim
103 words
A closure cap for a container, which cap is composed of flexible material and comprises a skirt adapted to fit over the open top of the container, an annular tongue which depends from the cap inside of the skirt and is adapted to extend into the top of the container and make sealing contact with the container, and a tonguelet which extends down from the cap between the skirt and the tongue, adjacent the tongue, there being an annular indentation that spaces the bases of the tongue and tonguelet and narrows the base of the tongue and tonguelet and gives them greater flexibility.
