Abstract
Abstract The invention relates to a container comprising a fluid containing pouch having at least one flexible upper wall portion made of an extensible plastic material. The upper wall portion is connected to a dispensing neck by deforming the upper wall portion into an annular recess into the dispensing neck and locking the same therein with an annular locking collar which is press fitted into the recess. The dispensing neck includes a translationally extending flange portion which will cooperate with a sleeve to secure the dispensing neck in an aperture of a supporting carton. The pouch and a portion of the dispensing neck are preferably made of dissimilar materials having low gas permeation characteristics to prevent the seepage of oxygen into the fluids in the container.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
170 words
A container comprising: a fluid containing pouch having at least one flexible upper wall portion; a dispensing neck with a dispensing aperture extending therethrough positioned on one side of said flexible wall portion and connected thereto, said dispensing neck having an annular tapered recess surrounding said dispensing aperture at one end thereof and adjacent said flexible wall portion and a closure receiving surface on the other end thereof; a wedging collar having a corresponding tapered external surface positioned on the other side of the flexible wall portion and wedged into said annular recess of said dispensing neck with the flexible wall portion fixedly wedged therebetween and deformed around said collar in said recess so as to minimize any possible leakage path through the flexible upper wall portion around the dispensing neck, said flexible wall portion having an aperture therein communicating with the aperture in the dispensing neck, and an integral flange portion positioned on said dispensing neck and extending transversely to the aperture in said neck for mounting the pouch.
Claim 2
Dependent Claim
170 words
A container comprising: a fluid containing pouch having at least one flexible upper wall portion; a dispensing neck with a dispensing aperture extending therethrough positioned on one side of said flexible wall portion and connected thereto, said dispensing neck having an annular tapered recess surrounding said dispensing aperture at one end thereof and adjacent said flexible wall portion and a closure receiving surface on the other end thereof; a wedging collar having a corresponding tapered external surface positioned on the other side of the flexible wall portion and wedged into said annular recess of said dispensing neck with the flexible wall portion fixedly wedged therebetween and deformed around said collar in said recess so as to minimize any possible leakage path through the flexible upper wall portion around the dispensing neck, said flexible wall portion having an aperture therein communicating with the aperture in the dispensing neck, and an integral flange portion positioned on said dispensing neck and extending transversely to the aperture in said neck for mounting the pouch.
Claim 3
Dependent Claim
32 words
The container of claim 1 in which the annular recess and the wedging collar have flared extremities to aid in locking the upper wall portion of the pouch in the annular recess.
Claim 4
Dependent Claim
24 words
The container of claim 1 in which the closure receiving surface on the dispensing neck is screw threads adapted to receive a screw cap.
Claim 5
Dependent Claim
40 words
The container of claim 1 in which the liquid containing pouch has the flexible wall portion positioned adjacent the dispensing neck and the wedging collar and in which the remainder of the pouch is a comparatively non-flexible and non-porous material.
Claim 6
Dependent Claim
35 words
The container of claim 4 in which the dispensing neck is made of a thermo-plastic material having low gas permeation characteristics and in which the sleeve member and collar are made of a thermoplastic material.
Claim 7
Dependent Claim
71 words
The container of claim 1 and including a carton surrounding said pouch with said dispensing neck extending through an aperture in said carton and with said flange portion on the dispensing neck bearing against a portion of the carton surrounding said aperture and adjacent said pouch, and including a sleeve member positioned over the dispensing neck and frictionally fitted thereon bearing against the other side of said carton surrounding said aperture.
Claim 8
Dependent Claim
23 words
The container of claim 6 in which the sleeve member and the dispensing neck have cooperating tapered surfaces in the area of engagement.
Claim 9
Dependent Claim
42 words
The container of claim 6 in which the flange portion of the dispensing neck and the sleeve member have cooperating surfaces to deform the surface of the carton surrounding the aperture therein and prevent rotation of the carton relative to the pouch.
Claim 10
Dependent Claim
25 words
The container of claim 8 in which the cooperating surfaces are spiked projections and depressions arranged on said sleeve member and said flange portion respectively.
Claim 11
Dependent Claim
37 words
The container of claim 6 in which the sleeve member includes a tubular portion fitted over the side of the dispensing neck and a flange portion extending substantially parallel to the flange portion on the dispensing neck.
Claim 12
Dependent Claim
19 words
The container of claim 10 in which the tubular portion is tapered to frictionally fit on said dispensing neck.
Claim 13
Dependent Claim
20 words
The container of claim 1 in which the flange portion of the dispensing neck is positioned intermediate the ends thereof.
Claim 14
Dependent Claim
28 words
The container of claim 1 in which the flange portion of the dispensing neck is positioned adjacent the end of the neck common to the annular recess therein.
Claim 15
Dependent Claim
31 words
The container of claim 1 in which the annular recess in the dispensing neck is substantially equal in depth to the length of the cap receiving surface on the dispensing neck.
Claim 16
Dependent Claim
19 words
The container of claim 1 in which the annular recess and said wedging collar have substantially the same dimensions.
Claim 17
Dependent Claim
146 words
The container comprising: a fluid containing pouch having at least one flexible upper wall portion, a dispensing neck with a dispensing aperture extending therethrough positioned on one side of said flexible wall portion and connected thereto; said dispensing neck having an annular tapered pouch receiving recess surrounding said dispensing aperture and formed in and extending from one end thereof; and a wedging collar having a corresponding tapered external surface positioned on the side of the flexible wall portion and wedged into said annular pouch receiving recess with said flexible upper wall portion of said pouch fixedly wedged therebetween and deformed around said wedging collar in said recess so as to minimize any possible leakage path through the flexible upper wall portion around the dispensing neck, said flexible wall portion having an aperture therein within said wedging collar and communicating with the aperture in the dispensing neck.
Claim 18
Dependent Claim
146 words
The container comprising: a fluid containing pouch having at least one flexible upper wall portion, a dispensing neck with a dispensing aperture extending therethrough positioned on one side of said flexible wall portion and connected thereto; said dispensing neck having an annular tapered pouch receiving recess surrounding said dispensing aperture and formed in and extending from one end thereof; and a wedging collar having a corresponding tapered external surface positioned on the side of the flexible wall portion and wedged into said annular pouch receiving recess with said flexible upper wall portion of said pouch fixedly wedged therebetween and deformed around said wedging collar in said recess so as to minimize any possible leakage path through the flexible upper wall portion around the dispensing neck, said flexible wall portion having an aperture therein within said wedging collar and communicating with the aperture in the dispensing neck.
Claim 19
Dependent Claim
29 words
The container of claim 16 in which the fluid containing pouch is comprised of the flexible upper wall portion coupled to a non-flexible material having low gas permeation properties.
Claim 20
Dependent Claim
55 words
The container of claim 16 and including a carton having an aperture therein surrounding said pouch with said dispensing neck of said pouch extending through the aperture in the carton; and including means positioned on said dispensing neck and engaging opposite sides of said carton surrounding said aperture for retaining said pouch in said carton.
