Abstract: A blow molded carrying chest which includes a frame and a lid is provided. The frame includes a base frame member, and left and right end frame members attached to the base frame member. A top frame member is rigidly attached to the left and right end frame members, and defines only a portion of a top surface of the chest. A lid is hingedly connected to the frame, and defines a remainder of the top surface of the chest not defined by the top frame member. The lid is pivotable from a closed position to an open position to provide access to an interior of the chest.

Abstract: A latch structure for a container having mating first and second portions and an improved container assembly, wherein said latch structure has improved strength characteristics. The side legs of the generally rectangular latch are canted so that the outer surface thereof falls away from the inner surface thereof.

Abstract: A blow molded hollow doubled wall article wherein the inner wall has an edge portion and a central portion adjacent the edge portion, including at least one opening in the central portion providing access to the space between the inner and outer walls and forming a flap member connected to said edge portion.

Abstract: A case for holding an elongated object is provided. The case includes a first containment portion for containing at least a first portion of the object. The first containment portion includes a door for exposing at least the first portion of the object. A second containment portion for containing at least a second portion of the object is also provided. The second containment portion is pivotally connected to the first containment portion and thereby pivotal relative the first containment portion through an angle having a magnitude for allowing clearance of the first portion from the first containment portion for allowing removal of the object from the first and second containment portions.

Abstract: A mold for controlling the weight and wall thickness distribution in a blow molded plastic manufactured article or a family or related articles involves simultaneous formation of the manufactured article and a waste article. The waste article is removed and recycled to manufacture further articles. The waste article forming chamber increases the apparent depth of the manufactured article chamber to create a larger apparent surface area, so that the parison is being blown over a much larger surface area, creating a reduced actual part weight and actual wall thickness.

Abstract: A hinge mechanism for a cover of a container such as a golf bag comprises a spine, and at least one door panel. The spine has a slot which extends vertically from its lower edge. A pin extends transversely across the slot. A radially outwardly extending rib is formed on the container and fits into the slot in the spine. The rib has a channel therein to receive and trap the pin. The cover is movable about the pin from an upright closed position to an inverted open position in which the cover is adjacent the container and usable as a receptacle.

Abstract: A method of manufacturing blow molded plastic cases of the type comprising two hollow hinged containers where at least one of the containers has a compartment, and a door for the compartment is presented. The method allows the manufacture of compartment doors as part of an integrated manufacture without requiring a separate blow molding step to make the door. The method comprises blow molding a standard size door as one face of a first hollow container, in an area of the container which would otherwise be cut out and discarded, removing the door from the container, storing the door for future use, and assembling the first hollow container with a second blow molded hollow container to make a first case. A third and fourth hollow container are blow molded, and an area sized to accommodate the door stock is cut from the third container. The door is retrieved from stock and mounted in the third hollow container.

Abstract: An apparatus is disclosed for preparing a tubular parison, which is continuously extruded in an extrusion direction from an extrusion head, and for subsequently transferring the parison to a blow molding machine. The apparatus provides improved control of the wall thickness of the parison and can be used with particular advantage in making articles requiring parisons of large diameter and length. The apparatus includes a parison stretching mechanism that grasps and seals the parison at one location along its length and stretches the parison at a controlled rate while being extruded in the extrusion direction. The apparatus also sequentially severs sections of the parison from the remaining continuously extruded portion and transfers each section to a stationary blow molding machine out of the path of this remaining portion.

Abstract: A tote device for an article, such as a chainsaw, having a main body and a member projecting from one side of the body, comprises a base for supporting the body when at rest. The base is formed with an upwardly open recess configured to receive at least a portion of the body. A scabbard is mountable on the member to enclose and protect at least a portion of it. A first linking arrangement links the scabbard, when mounted on the member, to the base in the region of the one side of the body and a second linking arrangement links the base to the body, when received in the recess, at a location remote from the one side. Accordingly, when the body and member are lifted, the scabbard is also lifted. Further, interaction of the scabbard and body with the base, through the first and second linking arrangements, also lifts the base.

Abstract: A molded plastic latch structure for molded two-part receptacles comprising a base and a cover forming a closure for various types of articles, wherein the latch structure includes opposed mounting lug and latching post members adjacent the confronting edges of the receptacle base and cover, and a latching buckle adapted to be secured to the lug member against accidental detachment from the base or cover, wherein the buckle incorporates a flexible bail for releasable engagement with the post member in the closed condition of the receptacle to maintain it in such condition.

Abstract: Relatively light gauge thermoplastic sheet material is pierced by a hot punch to provide a bearing aperture. The hot punch is held in sheet-penetrating position long enough to cause plastic flow of displaced material and formation of a collar-like hub surrounding the aperture. The hot punch is withdrawn and replaced by a cool punch to retard further plastic flow of the displaced material, thereby fixing the aperture in desired size and shape. There results a bearing aperture having an axial length greater than the starting thickness of the sheet material, and consequently a larger bearing surface integrally formed locally in the sheet material. Apparatus for forming the bearing aperture is also disclosed.
