Abstract: The container includes a peripheral side wall, whose upper peripheral edge defines a retention hook with a profile in the form of an inverted U, having an inner side leg, an arched base leg (lib) and an outer lateral leg (lie). An upper end wall of the container includes a median panel and a peripheral upper skirt having an end edge defining a closure hook with a profile in the form of an inverted U, having an inner side portion, an arched base portion, and an outer side portion which incorporates an upwardly projecting end flange. The closure hook is fitted onto the retention hook and radially inwardly deformed, compressing an elastic sealing element between the two hooks and maintaining the end flange projecting upwardly to the interior of the retention hook.

Abstract: The structure of a clinch portion of a mounting cup is provided which can retain a gasket. The clinch portion includes a curl portion continuous with an upper end of an outer circumferential wall at an inner circumferential edge of the curl portion, and a curl skirt portion having an upper end continuous with an outer circumferential edge of the curl portion. The curl portion is made of a plurality of curved planes having different radii extending from the inner circumferential edge to outer circumferential edge. A space a portion of the gasket can enter is formed between a virtual curved plane with a radius constituting the inner plane of the curl portion and an inner curved plane or an outer curved plane, or between the virtual curved plane and both the inner and outer curved planes.

Abstract: A barrel has an external metal cylinder and a plastic vessel. The external metal cylinder has a cylinder body, an open top and an open bottom. The plastic vessel has an inner space with a sealed bottom as well as a through top flange. The top flange of the plastic vessel is sleeved tightly into the external metal cylinder, and embedded into the internal curling portion formed by the open top of external metal cylinder. Moreover, the sealed bottom of the plastic vessel is extended into the open bottom of the external metal cylinder, and kept with a recessed spacing to the curling flange, while the bottom of the external metal cylinder is exposed. The barrel can be applied to toilet brush assemblies in order to reduce the manufacturing cost, prevent rust and facilitate the cleaning process with better economic benefits and applicability.

A portion of the first container is expanded and/or a portion of the second container may be narrowed so that first and second container is interlocked and form a double-walled container. The first and/or second containers may have ribs. An air gap between the first and second containers provides thermal insulation to contents of the double-walled container.

Abstract: Top cone for an aerosol can, including a formed metal sheet extending around a longitudinal central axis, and having a contour that includes, as seen in longitudinal cross section from the top downward, a top section intended for holding a valve cap, a cone section connected to the top section and leading to a countersink section and a flange section. The countersink section is essentially U-shaped whereby the outer leg of the essential U-shape, that is the leg being furthest removed from the central axis, is bent away from the central axis to form the flange section, and which cone section has a continuously increasing transversal diameter, wherein the top cone comprises strengthening means for strengthening the countersink section against pivoting toward the central axis.

Abstract: The present invention is directed to a method for joining two parts together and the unit derived therefrom. The method comprises the steps of mating a first flange portion extending along an entire periphery of a first part with a second flange portion extending along an entire periphery of a second part; overfolding a margin portion extending along an outer edge of the second flange portion to join the first part and the second part; a linear ridge being formed on at least one of the first flange portion, the second flange portion and the margin portion, the linear ridge extending along an entire periphery of the at least one portion and extending toward the first flange portion, the second flange portion or the margin portion which is opposed to the linear ridge in the overfolded state; and compressing the margin portion to plastically deform the linear ridge so as to form a seal between the two parts.

Abstract: For a pressurized container for dispensing a fluent material, and particularly an aerosol container, the cover or lid is domed, but is of sufficiently thin material that it might distort under elevated pressure in the container. To inhibit such distortion, one or both of the side walls of the cover recess, which is toward the periphery of the installed cover, are reinforced against deforming or stretching out of the container. In one embodiment, the radially inner wall of the recess engages the radially outer wall of the recess so that outward distortion of the dome of the cover is resisted by the stiffness of both engaged walls of the recess, strengthening the thin material domed cover against deformation under pressure in the container. Specifically, there may be annular ribs or other engageable deformations on walls of the recess that engage and thereby provide interference against the radially outer wall moving up out of the container upon the dome attempting to deform outwardly.

Abstract: A fluid container and capsule therefor. The capsule comprises upper and lower parts, at least one of which has a dished formation and both of which have a peripheral rim, the rims being secured together so that the upper and lower parts are at least partially in register with one another to provide at least one vented chamber extending into the dished formation. The capsule includes a vent hole or like structure in at least one of the parts to communicate between the interior of the chamber and the exterior thereof. The lower part has its exterior so formed as to enable it to be held in stable engagement with a surface but so that a fluid may pass freely between those parts of the exterior of the lower part and the surface that are not in intimate engagement.

Abstract: A partitioning member is provided at the opening of a thermal insulation box having outer and inner boxes forming a space in between the outer and inner boxes. The two spaces communicate with each other and are filled integrally with a thermal insulation material by injecting into the space between the outer and inner boxes an expandable thermal insulation material, which diffuses into the space inside the partitioning member, to thereby provide in a simple and economical way a thermal insulation box having a small number of components and uniform thermal insulation.

Abstract: The system (10) for collecting and disposing of personal-use hypodermic syringes (29) comprises a cylindrical container (11) and a telescopic cover 12. The container (11) includes a side wall (15) defining a collection chamber (19) for collecting used hypodermic syringes (29). The telescopic cover (12) includes an inner top wall (25) and an outer top wall (26) having an opening (28) therein, which is of sufficient internal breadth sized and shaped specifically for receiving hypodermic syringes (29). The used syringes (29) will be pushed through a scored portion (30) of the inner top wall (25), and then a barrel (31) portion of the syringe fits through the opening (28) formed by the outer top wall (26). The container (11) is sized and shaped so that once deposited in the collection chamber (19), the syringes (29) cannot turn end-for-end.

Abstract: An arrangement is disclosed for improving the seam strength of plastic containers produced by coextrusion blow-molding which are provided with a diffusion barrier layer incompatible with the base material. To improve the seam strength, the same is therefore designed as a web seam which is folded in labyrinthal shape and the folds of which are welded to each other. The length of the web seam in the unfolded state is equivalent to at least three times the thickness of the coextrudate and the web seam is folded at least doubly.
