Abstract
Abstract A nursing container assembly which includes a container member having an upstanding threaded neck portion for receiving a screwcap, with a nipple seated on the screwcap. A relatively thin wall closes the upper end of the neck portion and has score means on a portion thereof for facilitating separation of the wall when the wall is subjected to a concentrated pressure adjacent the score means. A projection means depends from the underside of the screwcap, spaced from the radial center of the screwcap, and has a blunt lower edge for separating the wall by a breaking action along the score means. The wall is recessed within the neck portion of the container member and comprises part of a crimp cap which is crimped over the outermost end of the neck and overlies the top marginal rim of the neck. An annular ridge depends from the underside of the screwcap and abuts against the portion of the crimp cap overlying the top marginal rim of the neck to provide a seal therebetween. The screwcap has a central opening about which the nipple is seated and a generally planar portion of the cap surrounds the opening. The nipple has a laterally extending peripheral flange dimensioned to overlie said marginal planar portion and a relatively fine scoring means is formed on the area of the planar portion to provide vent means between the nipple and the screw cap.

Dependent Claim
29 words
The combination of claim 1 wherein said generally planar portion of said container is formed of relatively rigid plastic material on which said means is formed as by sandblasting.
Claim 4
Dependent Claim
55 words
The combination of claIm 1 wherein said nursing container includes a container member, and a cap member of relatively rigid plastic material, said opening being formed in said cap member, said means defining said planar portion being formed on said cap member about said opening, and said nursing nipple being seated on said cap member.
Claim 5
Dependent Claim
63 words
In combination, a nursing container, a nursing nipple, means defining complementarily engaging surfaces of substantial area on said container and said nipple, the surface on the container being formed of generally rigid material, and means defining a fine eroded surface portion on substantially the entire area of the engaging surface of said container for providing vent means between the container and the nipple.
Claim 6
Dependent Claim
63 words
In combination, a nursing container, a nursing nipple, means defining complementarily engaging surfaces of substantial area on said container and said nipple, the surface on the container being formed of generally rigid material, and means defining a fine eroded surface portion on substantially the entire area of the engaging surface of said container for providing vent means between the container and the nipple.
Claim 7
Dependent Claim
87 words
A nursing container assembly, comprising a container member having an upstanding threaded neck portion terminating in an open mouth, a screwcap received on said neck portion, a nipple seated on said screwcap, and means defining an annular ridge depending from the underside of the screwcap and terminating in a sharp annular edge which abuts against the top marginal rim of said neck portion as the screwcap is turned onto full threaded engagement with said neck portion to provide a seal between said container member and said screwcap.
Claim 8
Dependent Claim
87 words
A nursing container assembly, comprising a container member having an upstanding threaded neck portion terminating in an open mouth, a screwcap received on said neck portion, a nipple seated on said screwcap, and means defining an annular ridge depending from the underside of the screwcap and terminating in a sharp annular edge which abuts against the top marginal rim of said neck portion as the screwcap is turned onto full threaded engagement with said neck portion to provide a seal between said container member and said screwcap.
Claim 9
Dependent Claim
30 words
The nursing container of claim 5 wherein at least said annular ridge on said screwcap is formed of plastic material providing sufficient resiliency for said sharp edge to facilitate sealing.
Claim 10
Dependent Claim
181 words
A nursing container assembly comprising, a container member having an upstanding threaded neck portion, a relatively thin, generally rigid wall closing the upper end of said neck portion, a screwcap received on said threaded neck portion and having a transverse wall portion overlying said thin wall when received on said threaded neck portion, a nipple seated on said transverse wall portion of said screwcap about an opening in said wall portion, score means formed on said thin wall in a circular pattern concentric with the axis of rotation of said screwcap, and projection means depending from the underside of the transverse wall portion of said screwcap, spaced from said axis adjacent to but not overlying said circular score means for applying concentrated pressure adjacent to and progressively along the score means in response to rotation of said screwcap as the cap is turned onto full threaded engagement with said neck portion so that said generally rigid thin wall will be separated by a breaking action along the score means and liquid within the container member can be extracted through the nipple.
Claim 11
Dependent Claim
181 words
A nursing container assembly comprising, a container member having an upstanding threaded neck portion, a relatively thin, generally rigid wall closing the upper end of said neck portion, a screwcap received on said threaded neck portion and having a transverse wall portion overlying said thin wall when received on said threaded neck portion, a nipple seated on said transverse wall portion of said screwcap about an opening in said wall portion, score means formed on said thin wall in a circular pattern concentric with the axis of rotation of said screwcap, and projection means depending from the underside of the transverse wall portion of said screwcap, spaced from said axis adjacent to but not overlying said circular score means for applying concentrated pressure adjacent to and progressively along the score means in response to rotation of said screwcap as the cap is turned onto full threaded engagement with said neck portion so that said generally rigid thin wall will be separated by a breaking action along the score means and liquid within the container member can be extracted through the nipple.
