Abstract
Abstract A unitary, hermetically-sealed dispensing container, having plural removable closures and suitable for containing and dispensing sterile solutions, is provided. The removable closures are unitary with the container. The dispensing container comprises a sealed, elongated shell of thermoplastic material provided with at least one access port at each end of the shell, a neck portion unitary with the shell and surrounding each access port, and removable cap means over the access ports and joined to the corresponding neck portions by means of frangible annular webs. The frangible annular webs are unitary with the cap means and with the neck portions. At least one of the neck portions is provided with a bore of predetermined controlled dimensions and is adapted to receive a draining spike or a similar means for withdrawing the contents of the container.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
179 words
A unitary, hermetically-sealed dispensing container, suitable for containing a sterile solution, which comprises a hollow, generally tubular body of thermoplastic material closed at both ends, defining an enclosure having first and second access apertures and provided at one of said ends with a first hollow stem means having a bore of predetermined configuration and surrounding the first access aperture and at the other of said ends with a second hollow stem means having a predetermined outer side surface configuration and surrounding the second access aperture, the end provided with said second access aperture being bifurcated so as to define a pair of pockets; a unitary sleeve member bridging said pockets and defining a confined flow passageway therebetween, said second hollow stem means communicating with said confined flow passageway, said first and second hollow stem means being unitary with said tubular body; a first removable closure means for sealing said first access aperture and unitary with said first hollow stem means; and a second removable closure means for sealing said second access aperture and unitary with said generally tubular body.
Claim 2
Dependent Claim
179 words
A unitary, hermetically-sealed dispensing container, suitable for containing a sterile solution, which comprises a hollow, generally tubular body of thermoplastic material closed at both ends, defining an enclosure having first and second access apertures and provided at one of said ends with a first hollow stem means having a bore of predetermined configuration and surrounding the first access aperture and at the other of said ends with a second hollow stem means having a predetermined outer side surface configuration and surrounding the second access aperture, the end provided with said second access aperture being bifurcated so as to define a pair of pockets; a unitary sleeve member bridging said pockets and defining a confined flow passageway therebetween, said second hollow stem means communicating with said confined flow passageway, said first and second hollow stem means being unitary with said tubular body; a first removable closure means for sealing said first access aperture and unitary with said first hollow stem means; and a second removable closure means for sealing said second access aperture and unitary with said generally tubular body.
Claim 3
Dependent Claim
24 words
The dispensing container in accordance with claim 1 wherein said sleeve member, together with said bifurcated end, define a hanger hole for said container.
Claim 4
Dependent Claim
137 words
A unitary, hermetically-sealed dispensing container, suitable for containing and dispensing sterile solutions, which comprises an elongated shell of thermoplastic material provided with a pair of access ports at one end of said shell and with a venting port at the other end of said shell, one end of said shell being bifurcated and defining a pair of pockets; a tubular connector member unitary with said shell and providing a passageway between said pockets; a collet unitary with said shell surrounding each of said access ports and said venting port, said unitary collet surrounding said venting port being situated on said tubular connector member; cap means unitary with said collets sealing each of said ports; and a frangible annular web joining at least one of said cap means to its corresponding collet at each end of said shell.
Claim 5
Dependent Claim
137 words
A unitary, hermetically-sealed dispensing container, suitable for containing and dispensing sterile solutions, which comprises an elongated shell of thermoplastic material provided with a pair of access ports at one end of said shell and with a venting port at the other end of said shell, one end of said shell being bifurcated and defining a pair of pockets; a tubular connector member unitary with said shell and providing a passageway between said pockets; a collet unitary with said shell surrounding each of said access ports and said venting port, said unitary collet surrounding said venting port being situated on said tubular connector member; cap means unitary with said collets sealing each of said ports; and a frangible annular web joining at least one of said cap means to its corresponding collet at each end of said shell.
Claim 6
Dependent Claim
28 words
The dispensing container in accordance with claim 3 wherein the distal ends of said pockets terminate in substantially coplanar lands that define the bottom surface for said container.
Claim 7
Dependent Claim
88 words
The dispensing container in accordance with claim 3 wherein the distal ends of said pockets terminate in substantially coplanar lands that define the bottom surface for said container, wherein said tubular connector member is spaced inwardly from the plane defined by said lands, and wherein the cap means for the unitary collet on said tubular connector member is provided with a tab means unitary therewith for facilitating removal of the cap means; said tab means being situated so as to allow said container to rest on said lands.
