Abstract:
A trash can wherein the open top of the container is surrounded by a ring-shaped rim having two inwardly extending prongs forming part of a bayonet mount. The lid of the can has a top portion and a depending annular skirt which can be inserted into the rim preparatory to activation of the bayonet mount which further comprises two inverted L-shaped slots in the external surface of the skirt. The lower ends of the slots are open to permit entry of prongs in response to placing of the lid onto the rim, and the lid is then turned relative to the container in order to cause the prongs to enter the substantially horizontal portions of the respective slots. The bayonet mount ensures that the lid cannot be separated from the container by dogs, bears, raccoons and/or other animals. In addition, the bayonet mount can maintain the top portion of the lid in substantial sealing engagement with the rim to prevent the escape of odors and/or flowable substances. The slots are disposed at the ends of a substantially diametrically extending grip at the upper side of the top portion of the lid to thus facilitate proper orientation of the lid prior to its connection to the container.
Abstract:
An especially configured, ringless, container-lid, design is disclosed having improved sealing characteristics applicable to paint containers for the consuming public. The rim portion of the container is provided with a tapered, especially shaped wall section terminating in a circular bead which is received in a sealing groove in the lid. The wall section flexes to maintain the seal established between the lid and the bead while sufficiently rigidized to prevent collapse of the container's sidewall. The design disclosed permits easy modification of the container for serially stacking thereof.
Abstract:
A lid closure assembly for a bin having a top wall and a circular passage through the top wall, the lid assembly comprising a generally circular lid member having a central portion and cylindrical rim portion with an outer diameter less than that of the passage, an outwardly open annular retaining groove in the rim portion having an O-ring seal disposed in the groove, and coacting means on the lid member and on the top wall of the bin for retaining the lid within the passage when the cylindrical rim portion of the lid member extends downwardly into the passage compressing the O-ring to maintain a seal.
Abstract:
A paint can having a body with a curl at its upper open end and a plug having a downwardly open groove defined by an upright wall formed to fit within the open end of the body, a radial bight which in the closed position of the plug overlaps the curl and compress a sealing band thereagainst, and an outer flange with an inwardly offset lower portion which snaps under the curl, the lower edge of the flange having an inturned curl which is sprung into an annular groove in the body wall, the portion of the wall defining the said annular groove forming an annular internal rib on the body which enters a complimentary groove in the plug side wall. A handle is provided connected to a band encircling the body and abuts the lower edge of the outer flange of the plug in the closed position, the band sliding upwardly with the handle and extending into the body curl when the plug is removed.
Abstract:
An apparatus for deforming an existing external curl on a tubular side wall of a container to form a crushed curl through the use of a first die having an annular groove of generally semi-circular cross section which engages a peripheral inside and outside portion of the curl to prevent lateral spreading thereof, a second die includes a convex generally V-shaped annular surface which enters into the annular groove of the first die, an imaginary line diametrically intersecting the V-shaped convex surface is also generally coincident with an imaginary line diametrically intersecting the annular groove, and upon relative movement of the die such that the convex surface enters into the annular groove, a portion of the curl is crushed into a generally V-shaped configuration.
Abstract:
The invention relates to a container, comprising: a tubular body with at least one open end, wherein a part of the body adjacent to the end is provided with a bent body rim; a cover closing the open end having a cover rim which grips over the bent body rim; and a locking ring encircling the cover rim and the bent body rim which assures against a relative displacement of the cover in relation to the body. In order to lessen the danger of the occurrence of open contact at the end wall portions, for example be dropping, the curled body rim is additionally curled and/or the body is provided with a groove extending over at least parts of the body circumference, on which a part of the locking ring turned away form the open end of the body can support, and/or the locking ring is provided with a release element arranged in and across it.
Abstract:
A reusable industrial drum is formed by temporarily joining the periphery of the end closure to the rim of the cylindrical shell by curling to produce a spiral seam. The outermost layer of the seam, consisting of a portion of the end closure, is cut to permit the end closure element and shell to be separated and disassembled. Further processing operations may take place on the closure element and shell separately. The closure element is thereafter re-mated with the shell, a seam sealant having previously been introduced between the parts, and a locking ring such as a bolt or chime ring is placed over the reassembled seam. The locking ring surrounds the periphery of the seam to hold the seam together. After use, the drum can be readily disassembled for reprocesing and reuse by simply removing the bolt or chime ring.
Abstract:
This relates to a can, preferrably formed of aluminum, which may be formed by a drawing process and which is so constructed wherein it may utilize wall thicknesses less than those which are presently commercially permissible so as to be suitable for the packaging of food products and the like which are either hot filled or subject to retorting and still commercially compete with three-piece steel cans. A primary feature of the can is the elimination of the customary double seam securing the end unit to the can body and replacing the same with telescoping of portions of the can body and end unit and providing an adhesive bond therebetween with the adhesive bond being enhanced by the reaction of the can body and end unit under conditions of internal pressure and internal vacuum due to the radial compression of the adhesive forming the adhesive bond to increase the shear strength of the adhesive. The end unit is provided with a securing flange which is connected to the end panel by a corner defining a line of weakness wherein the securing flange may be torn from the end panel and at the same time peeled from the can body.
Abstract:
A container, of which the body is downwardly tapered to interfit with others for storage or transport, has an outwardly extending circumferential top bead. A separate top ring is formed with an outer inverted annular channel for engagement on the top part and bead of the body, and is also formed with an inner annular channel to receive the downturned peripheral part of a conventional friction-fit lid.
