  • Patent number: 5072829
    Abstract: Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, and severable into individual carriers with integral handles along lateral edges. Integrally joined band segments define container-receiving apertures. Perforate lines, along which such stock is severable, divide certain cross segments into half segments. Each half segment has an aperture-defining edge configured with a nub countering tendencies of such half segment to neck down or to break.
    Type: Grant

  • Patent number: 5038928
    Abstract: Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, and severable into individual carriers with integral handles. For each carrier, integrally joined band segments define container-receiving apertures. Moreover, an integral handle is joined at its ends respectively to middle portions of two outer segments, which are joined to one cross segment at a node. Stresses are distributed from each end of the handle, through the outer segment having such end joined to a middle portion thereof, to two cross segments. Perforated lines divide alternate cross segments into half segments and facilitate severance of such stock to form the individual carriers. Each half segment has an aperture-defining edge configured to provide means, which may comprise a nub, for countering tendencies of such half segment to neck down or to break.

  • Patent number: 5020661
    Abstract: Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, for machine application to substantially identical containers. The stock is severable to form individual carriers with container-receiving apertures, as defined by band segments, which include outer segments formed with tear-open tabs. Each tab and the outer segment formed with such tab have multiple slits, which are arranged to define tearable bridges that can be easily torn by a user pulling on such tab, whereby the outer segment formed with such tab can be easily severed to release a container from the aperture bounded partly by such segment.

  • Patent number: 5018620
    Abstract: Carrier stock formed from a single sheet of resilient polymeric material, such as low density polyethylene, for machine application to substantially identical containers. The stock is severable, along transverse lines that are perforated, to form individual carriers with container-receiving apertures and additional apertures, as defined by band segments, and with integral handles. The additional apertures facilitate reconfiguration of the stock from an as-formed configuration to an application configuration. Band segments defining the container-receiving apertures at each end rank at each end rank at each edge row includes an outer cross segment, an outer edge segment, an inner cross segment, and an inner oblique segment. The inner cross segment extends from the outer edge segment to the margin of one of the additional apertures.

  • Patent number: 4974726
    Abstract: A generally planar paperboard or polymeric sheet for stabilizing a rectangular array of substantially identical cans of a type having an openable end with a chime and for covering substantial portions of the openable ends of the arrayed cans. Pairs of parallel slits in the sheet define can-stabilizing strips. The sheet is clippable onto the cans in such manner that portions of the chimes extend into the paired slits and that each strip fits, without folding such strip, under portions of two adjacent cans. A package for merchandising such cans can be readily assembled by steps that include providing such cans in a rectangular array and clipping the sheet onto the cans in the specified manner.

  • Patent number: 4474305
    Abstract: A tamper-evident container is supplied which has internal ribs adjacent the upper rim. The rim is provided with an external upwardly opening trough. A lid for the container has portions interfitting with the ribs to secure the lid in place. A portion of the lid overlies the upper rim of the container, and a depending skirt on the lid extends down into the trough about the upper end of the container whereby the skirt is initially hidden and protected against lifting thereof to remove the lid. The upper outer edge of the trough is provided with weakened areas including notches and, optionally indentations below the notches to facilitate tearing of the trough wall in the direction of plastic grain of the container. Such tearing of the wall permits lifting of the lid skirt to remove the lid, and provides a quick visual check that the container has been tampered with.
