US Patent:

42327210, Nov 11, 1980

Filed:

Apr 9, 1979

Appl. No.:

6/028151

Inventors:

Jerry D. Martin - Highland Park IL
Stephen J. Pearson - Ingleside IL
Gary A. Ward - Round Lake IL
David A. Winchell - Twin Lakes WI

Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

B65D 102

US Classification:

150 05

Abstract:

A molded collapsible solution container which container defines a chamber-defining body portion wall having an integral neck portion and shoulder portion at one end thereof. The container defines, in its normal, unstressed state, a transverse cross section which tapers from the shoulder portion progressively along a major portion of its length to a flat, sealed end portion at the end of the container opposite to the one end. In accordance with this invention, the shoulder portion is rectilinear in shape, with the wall circumferences of transverse cross sections preferably progressively decreasing in length along the container from adjacent the shoulder portion toward the opposite end. Opposed triangular gusset portions are preferably present in which the side of the gusset portion which is parallel to the shoulder edge is positioned directly against the shoulder edge, and the shoulder edge defines the shape of an enlarged, generally cylindrical section for ease of flexing. Flat areas are defined in the container wall between the gussets.

International Classification:

US Classification:

150 05

Abstract:

A molded collapsible solution container defines a chamber-defining body portion wall having an integral neck portion and a shoulder portion at one end thereof. The container defines a pair of opposed gusset portions adjacent the shoulder portion at opposite ends of the shoulder portion, with the shoulder portion defining opposed shoulder edges extending between the gusset portions. A pair of opposed lines of flexing weakness are defined in the collapsible solution container and exhibit an arcuate cross section which extends inwardly of the container. The opposed lines of flexing weakness are positioned on each side of the container in generally parallel relation to the opposed shoulder edges with the opposed lines of flexing weakness being longitudinally spaced from the shoulder edges by a distance which is proportioned to cause the opposed lines of flexing weakness to abut one another as the container collapses inwardly about the opposed shoulder edges. Accordingly, the abutting lines of flexing weakness inhibit further collapse of the container under the pressure of suction, to slow the rate of subsequent collapse.

Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

B29C 1707

US Classification:

264 89

Abstract:

A method of making a thin-walled tubular container. The container defines a head portion with access means to the contents of the container, and a tail portion defining a sealed line in the tail portion, joining sides of the container into a sealed end with a flat plastic piece being formed integral with the sealed line and extending away therefrom. In accordance with this invention, a pair of spaced rod members are formed as an integral part of the flat, plastic piece, the rod members extending transversely of the longitudinal axis of the container. The flat plastic piece also defines a portion thereof between the rod members which is thinner than any remainder of the plastic piece spaced from the rod members. Accordingly, the rod members and intermediate portion therebetween provide an improved and stronger tail seal.

Abstract:

A thin-walled tubular container and a mold for making it is disclosed. The container defines a head portion with access means to the contents of the container, and a tail portion defining a sealed line in the tail portion, joining sides of the container into a sealed end with a flat plastic piece being formed integral with the sealed line and extending away therefrom. In accordance with this invention, a pair of spaced rod members are formed as an integral part of the flat, plastic piece, the rod members extending transversely of the longitudinal axis of the container. The flat plastic piece also defines a portion thereof between the rod members which is thinner than any remainder of the plastic piece spaced from the rod members. Accordingly, the rod members and intermediate portion therebetween provide an improved and stronger tail seal. A novel method for making such containers is also shown.
