Abstract
Abstract A liquid diet feeding container assembly is disclosed which includes a container member such as a bottle having an upstanding neck portion which is sealed with a thin frangible metallic seal overlying the open mouth of the neck portion and which carries a screw cap overlying the seal. The cap contains tubular delivery means such as a nipple protruding outwardly therefrom and projection means depending from the underside thereof. The depending projection ruptures the seal when the cap is tightened into operative position, and deformable spacer means are provided which intervene between the cap and the upstanding neck portion of the container or seal and prevent contact of the projection with the frangible seal during shipment and storage. The spacer means are deformed when the cap is tightened into position to permit delivery of the liquid diet.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
184 words
In a liquid diet feeding container assembly which includes a container member for the liquid diet having an upstanding neck portion terminating in a top marginal rim circumscribing an open mouth portion, seal means comprising a relatively thin wall closing the upper end of the neck portion extending transversely across the entire inside of said neck portion generally in a plane spaced inwardly from the outer end of the neck portion so as to be recessed within said neck portion, and a cap received on said neck portion having a transverse wall portion overlying said seal means with annular projection means depending from the underside of said transverse wall portion, tubular means on said cap for delivery of said liquid diet, said thin wall being frangible on application of concentrated pressure thereto by said projection means when said cap is secured into position for delivery of said liquid diet, the improvement which comprises deformable spacer means intervening between said cap and the upstanding neck portion of said container said spacer means preventing contact of said Projection means with said frangible thin wall until deformed.
Claim 2
Dependent Claim
184 words
In a liquid diet feeding container assembly which includes a container member for the liquid diet having an upstanding neck portion terminating in a top marginal rim circumscribing an open mouth portion, seal means comprising a relatively thin wall closing the upper end of the neck portion extending transversely across the entire inside of said neck portion generally in a plane spaced inwardly from the outer end of the neck portion so as to be recessed within said neck portion, and a cap received on said neck portion having a transverse wall portion overlying said seal means with annular projection means depending from the underside of said transverse wall portion, tubular means on said cap for delivery of said liquid diet, said thin wall being frangible on application of concentrated pressure thereto by said projection means when said cap is secured into position for delivery of said liquid diet, the improvement which comprises deformable spacer means intervening between said cap and the upstanding neck portion of said container said spacer means preventing contact of said Projection means with said frangible thin wall until deformed.
Claim 3
Dependent Claim
19 words
The container assembly of claim 1 wherein said spacer means depends from the transverse wall portion of said cap.
Claim 4
Dependent Claim
25 words
The container assembly of claim 2 wherein said spacer means is in frictional engagement with the inside surface of the neck portion of said container.
Claim 5
Dependent Claim
