CLOSURE WITH FRACTURABLE AUXILIARY CONTAINER
First Claim
1. A closure for bottles, flasks and the like designed for the extended storage of separate products comprising a generally cupshaped container, said container having an abutment surface axially spaced from a bottom wall, a closure, said closure having an end panel and a depending peripheral skirt with means on the latter for securement to a main container, means carried by said closure for limiting axial motion of said closure relative to said cup-shaped container by contacting said abutment surface during the application of the closure to a main container whereby a cutter adapted to be housed within said cup-shaped container is incapable of severing said bottom wall, said axial motion limiting means being a sealing member depending from and integral with said end panel and adapted for insertion into a container neck, said cup-shaped container includes radially outwardly directed flange means for abutting an outer container lip, said flange having axially spaced surfaces, one of said surfaces remote from said bottom wall is said abutment surface, a collar forming an extension of said peripheral skirt, said collar being connected to said peripheral skirt by breakable connections, inwardly directed projections on said collar, an outer container having a neck housing said cup-shaped container with said flange on a lip thereof, radially outwardly directed projections on said outer container neck for cooperating with said collar projections to rupture said breakable connections upon rotative removal of said closure, and the axial length of said collar and the minimum axial spacing of said container projections from said peripheral skirt is greater than the axial distance between said flange surfaces.

Abstract
This disclosure relates to a closure for hermetically sealing bottles, flasks and the like having a peripheral skirt and an end panel, and an auxiliary container internally of the peripheral skirt in generally suspended relationship from the end panel, a product and a cutter housed within the auxiliary container whereby upon the depression of the cutter a bottom closed wall of the auxiliary container is ruptured and the product therewithin is dispensed into a main container carrying the closure, and the auxiliary container being further so constructed as to provide hermetic sealing of both the main or auxiliary containers for separate storage of a product in each, further providing a hermetic seal during the admixture of the products, and finally maintaining a hermetic seal during repeated reclosures.

1. A closure for bottles, flasks and the like designed for the extended storage of separate products comprising a generally cupshaped container, said container having an abutment surface axially spaced from a bottom wall, a closure, said closure having an end panel and a depending peripheral skirt with means on the latter for securement to a main container, means carried by said closure for limiting axial motion of said closure relative to said cup-shaped container by contacting said abutment surface during the application of the closure to a main container whereby a cutter adapted to be housed within said cup-shaped container is incapable of severing said bottom wall, said axial motion limiting means being a sealing member depending from and integral with said end panel and adapted for insertion into a container neck, said cup-shaped container includes radially outwardly directed flange means for abutting an outer container lip, said flange having axially spaced surfaces, one of said surfaces remote from said bottom wall is said abutment surface, a collar forming an extension of said peripheral skirt, said collar being connected to said peripheral skirt by breakable connections, inwardly directed projections on said collar, an outer container having a neck housing said cup-shaped container with said flange on a lip thereof, radially outwardly directed projections on said outer container neck for cooperating with said collar projections to rupture said breakable connections upon rotative removal of said closure, and the axial length of said collar and the minimum axial spacing of said container projections from said peripheral skirt is greater than the axial distance between said flange surfaces.

2. The closure as defined in claim 1 wherein said closure projections are elastically deformable and extend circumferentially obliquely in the direction of closure removal rotation.
-
3. A closure for bottles, flasks and the like designed for extended storage of separate products comprising a generally cup-shaped container, said cup-shaped container having a generally tubular body closed at one end by a bottom wall and provided opposite thereto with a radially outwardly directed peripheral flange adapted to seat upon the lip of a container or the like, a tubular rupturing element housed within said cup-shaped container, a cap, said cap including an end panel and an internally threaded peripheral skirt, a tubular extensioN depending from said end panel in exterior telescopic relationship to said rupturing element, said rupturing tubular element having a cutting end adjacent said bottom wall and a force applying end remote therefrom, a space between said end panel and said force applying end, said space being normally maintained by said tubular extension resting upon said flange, and said tubular extension being externally dimensioned to form a seal with the interior of said cup-shaped container.
-
4. The closure as defined in claim 3 wherein said tubular body includes upper and lower generally cylindrical portions with a conical portion therebetween, a radially inwardly directed peripheral seat carried by said upper cylindrical portion, and said rupturing element being externally dimensioned so as to form a seal with said peripheral seal.
