Abstract: A thermoplastic squeeze tube has a self-sealing orifice where a one-way valve member is secured in the tube neck and an exposed portion thereof enclosed and protected by a frangible closure member integral with the neck portion. A pocket in the bottom wall of the frangible closure member closely encloses the one-way valve member to seal the same. A replacement cup-shaped closure member may be provided to reseal the tube after removal of the frangible closure member, which may have downwardly depending sealing protrusions which contain the upper portion of the exposed section of the one-way valve member to reseal the same.

Abstract: A rigid thermoplastic squeeze container having a self-sealing dispensing valve, for use with flowable substances, has a cylindrical shell with a body portion, a first sealable open end and an opposite end having a head portion with a dispensing orifice closed off by a self-sealing valve. A thermoplastic cylindrical support sleeve is fitted within the cylindrical body portion which extends from a position adjacent the head portion to a location spaced from the sealable end of the cylindrical body portion of the shell, such that that end can be sealed. The cylindrical shell and cylindrical body portion may be bonded together, and the head portion of the cylindrical body portion of the shell may have a downwardly depending flange to trap an end of the cylindrical support sleeve between the flange and the cylindrical body portion.

Abstract: A package including a container assembly, such as a tube having a dispenser spout, and a closure assembly having a concealed hinge, is provided for use in dispensing a consumer product such as toothpaste or medicinal ointment. The concealed hinge of the closure assembly permits a lid to be opened up to 180.degree. away from an associated closure base to provide maximum access to the container assembly to which the closure assembly is assembled. The closure assembly, including the lid and base, is capable of being molded in a single mold cavity and having maximum ease of opening and closing together with either one or two seals.

Abstract: A rotatable spout dispensing tube has a tubular member and associated closure cap with a nozzle. The tubular member neck portion has a planar wall with a central discharge aperture and an upwardly extending arcuate projection, the projection having a gap therethrough. The closure cap has a top wall with a spout thereon, the spout having a passageway which communicates with a central bore, the bore surrounded by a circular rim that seats in the central discharge aperture of the tubular member. An arcuate channel is also provided in the closure cap top wall in which the arcuate projection on the tubular member is slidably fitted. Contents of the tubular member are dispensed by aligning the passageway of the spout with the gap in the arcuate projection and application of pressure on the side wall of the tubular member.

Abstract: A closure especially adapted for use with a dispenser spout, said closure having a concealed hinge arranged to permit the lid to be opened 180.degree. away from its associated base to provide maximum access to a container to which the closure is assembled, the closure, consisting of a closure base and a lid, being capable of being molded in a single mold cavity.

Abstract: A thermoplastic tube, and method for forming such a tube, has a tube body portion formed from an inner layer of thermoplastic material, a barrier layer, and an outer layer of thermoplastic material. The outer layer does not extend completely about the periphery of the tube body and a strip of thermoplastic material having the same composition as the inner layer, fills each gap in the outer layer to form a smooth surface about the tube. The strip may be transparent or of a color different than the color of the outer layer. In a preferred tube, a first layer of adhesive material is provided between the inner layer and the barrier layer, and a second layer of adhesive material is provided between the barrier layer and the outer layer and strip.

Abstract: A headed thermoplastic tube is formed solely from a thermoplastic extruded, stretched, cylinder by positioning the cylinder over a forming mandrel with an exposed portion. The inner surface of the exposed portion is heated above the glass transition temperature of the thermoplastic material to render the inner surface molten while the outer surface provides support for the exposed portion of the cylinder. The heated exposed portion is then shaped into a conical shape, such as by heating the outer surface, and pressure applied to the conical shaped exposed portion to form a headed thermoplastic tube. The headed tubes produced have a body portion, shoulder portion and neck portion, without any seams, all of which are formed from the starting thermoplastic extruded, stretched cylinder.
