Abstract
Abstract This disclosure relates to closures for aseptic filled containers, and more particularly to a closure which includes a tubular body open at opposite ends, the tubular body being threadably or otherwise conventionally secured to a container finish with the container mouth being closed by a puncturable but self-sealable membrane. The hermetically closed but empty container is thereafter sterilized by retorting, irradiation, or by the injection of a small amount of a sterilizing gas into the container by a needle passed through the puncturable membrane. Thereafter the container is ready for subsequent filling by use of a conventional double-hollow needle technique after which the closure is completed by securing a disc to the closure body immediately above the puncturable membrane.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
123 words
A closure particularly adapted for aseptic packaging comprising a closure body including an end panel and a depending peripheral skirt having axially remote upper and lower end portions, means for securing said peripheral skirt to a container finish, a membrane in said closure body adjacent said end panel, said membrane being constructed from puncturable and selfsealable material, said peripheral skirt including radially inwardly directed support means positioned above said membrane, said support means and an inner peripheral surface of said upper peripheral skirt end portion defining a chamber, said end panel being a separate element housed in said chamber and seated upon said support means, and means permanently securing said end panel to said closure body in seated relationship upon said support means.
Claim 2
Dependent Claim
123 words
A closure particularly adapted for aseptic packaging comprising a closure body including an end panel and a depending peripheral skirt having axially remote upper and lower end portions, means for securing said peripheral skirt to a container finish, a membrane in said closure body adjacent said end panel, said membrane being constructed from puncturable and selfsealable material, said peripheral skirt including radially inwardly directed support means positioned above said membrane, said support means and an inner peripheral surface of said upper peripheral skirt end portion defining a chamber, said end panel being a separate element housed in said chamber and seated upon said support means, and means permanently securing said end panel to said closure body in seated relationship upon said support means.
Claim 3
Dependent Claim
40 words
The closure as defined in claim 1 wherein said peripheral skirt is formed as a pair of peripheral walls, means for securing said walls to each other, and cooperative means carried by said walls for clampingly securing said membrane therebetween.
Claim 4
Dependent Claim
33 words
The closure as defined in claim 1 wherein said membrane is disposed beneath said support means and is adapted to be held in seated relationship against said support means by a container lip.
Claim 5
Dependent Claim
42 words
The closure as defined in claim 1 wherein said support means is defined by a radially inwardly directed peripheral flange, said peripheral flange being defined by upper and lower annular walls, and said end panel being seated upon said upper annular wall.
Claim 6
Dependent Claim
30 words
The closure as defined in claim 4 including a container finish terminating in a sealing lip, and said membrane is clamped between said sealing lip and said lower annular wall.
Claim 7
Dependent Claim
46 words
The closure as defined in claim 5 wherein said upper and lower annular walls merge with respective upper and lower inner peripheral walls of said peripheral skirt, and said upper inner peripheral wall is of a larger diameter than that of said lower inner peripheral wall.
Claim 8
Dependent Claim
47 words
The closure as defined in claim 2 wherein said cooperative means is defined by said support means carried by one of said pair of peripheral walls and other support means carried by another of said pair of peripheral walls with said membrane being in sandwiched relationship therebetween.
Claim 9
Dependent Claim
15 words
The closure as defined in claim 2 wherein said securing means are cooperative screw threads.
Claim 10
Dependent Claim
24 words
The closure as defined in claim 7 wherein said first and another support means are a pair of spaced radially inwardly directed peripheral flanges.
Claim 11
Dependent Claim
44 words
The closure as defined in claim 9 wherein said securing means are cooperative screw threads carried by said pair of peripheral walls whereby the clamping force exerted upon said membrane can be regulated by the degree of tightening of said pair of peripheral walls.
Claim 12
Dependent Claim
32 words
The closure as defined in claim 10 inclUding a container finish terminating in a sealing lip, and sealing means disposed between said sealing lip and the peripheral flange most closely adjacent thereto.
