  • Patent number: 10569954
    Abstract: The invention relates to a trash can (1) having an injection-molded plastic body (2) formed by side walls (3, 4, 5, 6) and a bottom wall (8) positioned relative to each other such that the side walls and the bottom wall together define a cavity (15) having an opening (17) opposite the bottom wall (8), each side wall (3, 4, 5, 6) integrally merging into the adjacent side walls at common corners (11, 12, 13, 14), and a stand strip (26) extending at least partially along edges (27, 28, 29) of a lower face (25) of the bottom wall (8) directed away from the cavity (15) is provided on the lower face (25) and has curved short stand-strip segments (30, 31) at some of the common corners (11, 12, 13, 14) joined to long stand-strip segments (32, 33, 34), characterized in that the curved short stand-strip segments (30, 31) are at least partially decoupled from the long stand-strip segments (32, 33, 34) by cutouts (35, 36, 37, 38).

  • Patent number: 9045264
    Abstract: The invention relates to a container (1) having a cover (2) which is connected to the container (1) by at least two hinge arrangements (3) so that it can be opened and closed about a pivot axis (a) relative to the container (1). For permanent attachment of the cover to the container each hinge arrangement (3) comprises: a hinge gudgeon (4) disposed on the cover (2) with a casing section (5) formed in some sections in a dish shape on which a web (6) extending in the direction of the pivot axis (a) is formed; and a slot (7) introduced into the upper edge region of the container (1) and extending in the direction of the pivot axis (a) for receiving the casing section (5) formed in some sections in a dish shape, wherein the extent (b) of the casing section (5) together with the web (6) measured in the direction of the pivot axis (a) is greater than the extent (c) of the slot (7) measured in the direction of the pivot axis (a).

  • Patent number: 8646639
    Abstract: The invention relates to a device for unlocking swing-action side walls (2 to 5) which are hinged on the base (6) of boxes and/or containers (1), of which the two opposite end walls (4, 5) can be locked to the two adjacent side walls (2, 3) and unlocking takes place by virtue of a lifting movement of a bracket-like actuator (13), which interacts with a movement-deflecting means (16, 17), and wherein unlocking crosspieces (19) act on spring-tongue-like locking means (10) of the side walls (4, 5), these locking means being latched into the end walls (2, 3), and force them out of their latching seat, in which they clamp the end walls (2, 3).

  • Patent number: 8469216
    Abstract: The invention relates to a device for unlocking foldable side walls (2 to 5) hinged on the floor (6) of boxes and containers (1), the two opposite end walls (4, 5) thereof being lockable to the adjacent side walls (2, 3) and the unlocking taking place by a lifting motion of a yoke-like adjusting member (13) disposed under spring pretension and guided in recesses of stiffening ribs (11, 12) in the outer surfaces of the end walls (4, 5). The adjusting member (13; 130) is designed having motion-diverting means (16, 17) on the two outside ends thereof, said means diverting vertical motion into a horizontal motion unlocking the side walls when the adjusting member (13) is raised, wherein the unlocking bars (19) of the adjusting member act on spring tab-like locking means (10) of the side walls (4, 5) engaged in the end walls (2, 3) and press them out of engaged seating thereof surrounding the end walls (2, 3).

  • Patent number: 8286828
    Abstract: A storage/transport container has a plurality of walls defining an upwardly open vessel having an upper rim and a generally flat cover panel hinged on one of the walls and having an inner edge. The rim has opposite to one of the walls structure forming another inner edge. The cover panel is pivotal into a closed position with the inner edges juxtaposed, retaining formations projecting generally perpendicularly from the inner edge of the cover panel and oppositely from the other inner edge that fit together in the closed position. Hooks are formed on the edges and positioned so as to be opened directly at each other in the closed position. The hooks normally are spaced apart but, on deformation of the cover panel, hook together and preventing separation of the edges.
