Abstract:
A container is disclosed, generally having an open top defined by an annular rim, a base, and a sidewall extending between the top and the base. The sidewall has two arcuately formed longitudinal recesses, an annular rib, an annular shoulder located between the longitudinal recesses and the base, and a lower portion extending between the annular shoulder and the base. The annular shoulder is characterized by two arched portions aligned with the longitudinal recesses, and the lower portion has two beveled portions aligned with the longitudinal recesses. This container is more ergonomic, and has greater sidewall strength and rigidity, than existing containers.
Abstract:
A thin wall metal can is described having a converging neck portion and cylindrical chimney with a threaded sleeve encircling the chimney and restrained from rotation on the chimney by splines on an inner surface of the sleeve firmly engaged against an outwardly projecting shoulder on the can between the neck portion and chimney. The sleeve receives a threaded closure for closing and sealing the can.
Abstract:
A sports equipment carrier for carrying golf clubs and the like having a tubular substantially rigid body comprised of a sidewall that is ribbed or honeycombed along its longitudinal length for producing a high strength-to-weight sports equipment carrier body capable of being used as a golf bag and which is convertible to a shipping container when a removable substantially rigid lid is attached. In one embodiment, the carrier has a plurality of pairs of axially spaced apart radially extending transverse and annular ribs distributed along the longitudinal length of the body. In another embodiment, the ribbed sidewall comprises a single spiraling rib. In a still further embodiment, the sidewall is comprised of radially extending honeycomb cells forming a honeycombed portion that extends about a periphery of the carrier body and which is distributed the entire length of the sidewall. The ribs or honeycombs can be integral with the sidewall with the sidewall and ribs or honeycombs constructed of high density polyethylene, a polyolefin, plastic material. The exterior of the carrier body can be covered with fabric that can be colored to provide an aesthetically pleasing exterior that also protects the carrier body. The carrier can also have storage pouches, a carrying strap, and wheels, all of which are removable to facilitate conversion of the carrier to a shipping container.
Abstract:
Thin wall metal cans are described having threaded necks for receiving threaded closure to seal contents in the cans. Techniques for forming such threaded cans are also provided.
Abstract:
A reinforced finish is on a blow-molded container. An insert is permanently attached on the finish of a preform from which the container is blown, or directly on the finish of the blow-molded container. The insert is ring-shaped, forms a portion of the top surface of the finish, is made from a rigid plastic material, and is positioned entirely above the threads.
Abstract:
A rim structure for a metal container, such as a paint can, wherein the cylindrical sidewall of the container has adjacent its upper edge an outwardly diverging wall part which is folded over onto itself to form an outer top flange having a rounded cross section which extends radially inwardly. This top flange, at its radially inner edge, downwardly converges inside the outer wall part to define an inclined intermediate flange which projects axially downwardly to the vicinity where the exterior wall part diverges from the cylindrical sidewall. At this location, the intermediate flange is folded radially inwardly and upwardly to define a V-shaped fold which, on its radially inner side, defines an axially upwardly projecting inner flange for defining the container mouth. This inner annular flange has the inner surface thereof disposed substantially axially aligned with the inner surface of the cylindrical sidewall. This inner flange, at its upper end, is folded radially outwardly over onto itself to define an inner annular top flange which is radially spaced concentrically inwardly from the outer top flange, and is slightly axially lowered relative thereto. A lid can be sealed to the rim structure by inserting a depending flange into the region between the inner and outer top flanges.
Abstract:
A plastic blow molded container (20) for holding liquids includes a rectangular body portion (22) having at least one rib (44,46) extending completely around the container and having a construction that facilitates assembly of a unitary valve (42) to a dispensing spout (40) while maintaining flatness of side walls of the container during use. Each rib (44,46) has curved rib portions (48) extending along a pair of longer side walls (28). Each rib also has a relatively shallow rib portion (50) adjacent one shorter side wall (30) to prevent excessive compression thereof as the unitary valve (42) is pressed onto the dispensing spout (40). Each rib also has a relatively deep rib portion (52) along another shorter side wall (32) to maintain its flatness with the container filled and supported on the one shorter side wall (30) for the liquid dispensing through the valve (42). A top closure (38) of the container in addition to including the dispensing spout (40) includes a central handle (70) and a vent hump (72) having a label surface (74) that is inclined at about forty-five degrees with a vent (76) at its lower extremity to facilitate the liquid dispensing by admitting air into the container.
Abstract:
A container assembly having a cylindrical container body and a substantially circular container lid is provided with inwardly extending annular reinforcing ribs on an inner surface of the container body in the region of the mouth thereof and with angularly equispaced radially extending reinforcing ribs on the container lid extending from a V-shaped annular channel at the periphery of the lid substantially to an indented circular area at the center thereof. Closure of the lid to the body is effectuated by means of a pair of longitudinally spaced annular shoulders on an inside surface of the container body and a pair of complementary annular lips on the container lid, as well as a third annular shoulder on an outside surface of the container body and a corresponding annular lip on the container lid. One of the inner shoulder surfaces on the container body is disposed in substantially the same transverse plane as the annular shoulder located on the outer surface of the container body.
Abstract:
A drum apparatus includes an injection-molded or extruded rim member formed into a ring shape and permanently attached to a blow-molded thermoplastic drum body around the top portion of the drum adjacent to the sidewall section of the drum body. The rim member includes an inwardly, radially projecting annular protuberance which is juxtaposed adjacent an annular groove in the drum just below the top of the drum. The rim member is attached to the drum while the rim member is at an elevated temperature by positioning the rim around the drum. As the temperature of the rim member decreases, the diameter of the rim member decreases causing the annular protuberance to seat into the drum's annular groove. The rim member also has a grasping beak which provides an outwardly extending support lip, a top edge providing a stacking ridge which is positioned vertically over the sidewall of the drum, and an annular seizing surface facing radially inwardly. A short chain hoist groove is formed in the bottom of the drum.
Abstract:
An improved container for storing frozen foods such as ice cream comprising a base, a cylindrical body member joined to the base, and a rim disposed on the end of the body member which includes an edge projecting radially outwardly therefrom perpendicular to the longitudinal axis of the container. A cover adapted for slidable positioning over the rim has spaced-apart annular ridges on the inner surface thereof between which the edge of the rim is received for securing the cover on the body member.
