Abstract: Plastic container (110), including a side wall (120) and a flexible portion (132) of a base (130). The flexible portion of the base deflects when the sealed plastic container experiences a differential pressure. The deflection of the flexible portion of the base acts to change the internal volume of the container and thereby reduce the differential pressure. The container is a retortable container. The container may be injection-molded with inner and outer plastic layers (460,462) and a core layer (464) between the inner and outer plastic layers.

Abstract: An elastomeric containment receptacle has at least one sidewall defining a container substantially surrounding and enclosing a predetermined volume for housing a substance to be contained within the receptacle. The at least one sidewall includes a substance-contacting surface. The receptacle is reversibly transformable between a first stable conformation, wherein the substance-contacting surface faces inward, and a second stable conformation, wherein the substance-contacting surface faces outward. In other words, the receptacle is fully eversible, allowing for facile cleaning and drying of the receptacle interior. The receptacle possesses sufficient structural strength to stand without extraneous support. The eversible receptacle can be adapted to serve as a nursing bottle or other beverage receptacle. The receptacle can include a nipple or other receptacle cap, and an attachment joint for securing the cap to the elastomeric receptacle.

Abstract: An insert (1) for a closure provides, in a single component, a gasket function between the end panel (12) of the closure and the end sealing surface (22) of a container neck finish (20), a thread forming feature (3) and a tamper evident band (5). The sealing portion (gasket (2) and thread forming feature (3)) of the insert is formed from soft pliant material so as to provide excellent sealing. The tamper evident band (5) is made from much stiffer material than that of the sealing portion, thereby providing rigidity to the entire component. During assembly the integral tamper evident band (5) thus maintains the insert in a circular and non-twisted shape, ensuring ease of handling of the insert.

Either the container neck or the closure has a helical thread which engages axially extending ribs on the other of the container neck or closure to form indentations in the ribs which act as threads, teeth or a track for unthreading. A continuous or rotary seal is used between the container neck and the closure which does not require a sealing force from the threaded connection.

Abstract: A removal torque-resistant closure and container assembly is provided with the container having a thread extending around the opening. The closure includes a thread for engaging the container thread. The container includes a projection that extends from the thread root between two adjacent thread crests on the container and that defines an outer edge for temporarily deforming the closure thread during relative rotational movement of the container and closure when the container and closure are screwed together. Upon termination of the screwing action, the container projection edge is engaged with a deformed region of the closure thread so as to resist closure removal by unscrewing.

Abstract: A removal resistant closure and container assembly is provided. The container defines an opening. The closure is applied to the container to occlude the opening. A first thread is defined by the container and extends at least partially around the opening from a leading end to a trailing end. A second thread is defined by the closure and extends at least partially around the closure form a leading end to a trailing end. A projection is defined adjacent one of the first and second threads. The projection and the one thread define a space between them which is less than the width of the other of the threads. Either the projection or the other thread, or both, are resilient to accommodate deformation during relative rotational movement of the container and closure. When the closure and container are screwed together, the threads are relatively axially displaced from a threadingly engaged condition to a disengaged condition which resists re-engagement.

Abstract: A fastening structure of a tube and cap assembly is provided. The structure includes an unthreaded part formed in the threaded portion of cap or of a mouth member of tube. The unthreaded part acts as a stopper to keep the cap being secured to the mouth member of tube, but if the cap is forcibly screwed further, the unthreaded part is rolled and deformed by the other threaded portion which does not include the unthreaded part to form threads on the unthreaded part. Due to this forcible action, a conical cutting edge, if it is provided on the inner bottom surface of cap, is pressed against the sealed mouth of tube to break the sealed mouth.

Abstract: An access plug for providing a removable closure for a threaded hole in a housing of an electric starter or the like. The access plug is formed of a plastic molding material and has a cap member and a retainer member that are joined by a thin annular frangible portion. When assembling the plug to the threaded hole the plug is aligned with the hole and one end of the plug engages the housing. A tool now applies an axial force to the plug which causes the retainer member to be inserted into the hole, causes the frangible portion to be sheared or broken and causes a portion of the cap member to be inserted into the retainer member. When the frangible portion breaks a bead on the retainer member remains which is engaged by a ratchet tooth of a series of ratchet teeth formed on a part of the cap member.

Abstract: A self-threading container closure for a spiral wound tube useful as a container for fluids under pressure. The closure insert includes side threads in conjunction with a spherical arch and support legs. The threads permit the insert to be screwed into the walls of the tube and allow the spiral wound media to form around the closure in a liquid and pressure tight seal. This seal is enhanced by a transfer of outward fluid pressure on the spherical arch through the support legs to the threads and container walls.

Abstract: The invention relates to the gasketting of cap blanks, to be closed onto bottles or other containers.The gaskets lie across the more or less flat top of the cap blank and the invention is concerned with the peripheral part of the gasket, i.e. that part which occupies the corner of the cap between the flat top and the skirt.One kind of closing operation in which a gasketted cap blank is closed onto a bottle neck involves so-called "reform", i.e. a lateral pinching action at the top of the skirt. To aid closing the bottle cap symmetrically on the bottle, the peripheral part of the gasket includes a relatively flat step portion.
