Publication number: 20030010743Abstract: The invention concerns improvements to containers, in particular plastic bottles, having a body (2) with a circular non-cylindrical wall, so as to reinforce them and prevent cross-section variation when they are subjected to compression forces. Part at least of the wall is provided with a substantially planar relief. The wall is reinforced with peripheral grooves (26, 27, 28, 29 30) oriented in planes substantially perpendicular to the longitudinal axis (X) of the container, and the part comprising a substantially planar relief is run through with several grooves. The invention is characterized in that the width of each of the grooves is such that it is less wide (L2) where it emerges in said part of the wall than at the middle (L1) of its crossing. The invention is particularly useful for reinforcing large capacity bottles.Type: ApplicationFiled: July 25, 2002Publication date: January 16, 2003Inventor: Michel Boukobza

Patent number: 5894041Abstract: A blank (2) is molded for the manufacture of a multi-layer preform (1). The blank possesses protrusions (5). After the protrusions (5) have been brought to a plasticised state under the action of heat, those surfaces that contain protrusions (5) are covered by a layer of plasticised material. The blank (2) becomes connected to the layer (6) in the area of the protrusions (5). After cooling of the preform created from the blank (2) and the layer (6), the blank (2) will be connected with the layer (6) by means of microweld positions (7) in the area of the said protrusions (5). With that, delamination of the preform (1) during further processing or use-will be effectively prevented.Type: GrantFiled: October 11, 1995Date of Patent: April 13, 1999Assignee: Crown Cork & Seal Technologies CorporationInventor: Stephen W.

Patent number: 5814383Abstract: A container with improved crease-crack resistance and a method of making that type of container. The container utilizes a layer of a soft plastic on its exterior to control cracking at outward creases. When the container holds motor oil, the oil itself may plasticize the stiff material on the container's interior to preclude inward crease cracking. In this case, the stiff layer should have a sufficient thickness that an adequate amount of material remains unaffected by the oil and does not lose its rigidity or jeopardize the container's structural integrity. Where the contents do not provide the requisite improvement in inward crease cracking or would completely soften the stiff layer, then the container has a separate, soft, third layer of plastic on the interior of the container. The softness of this layer protects against inward crease cracking. It may also protect the stiff layer from softening by the bottle's contents.Type: GrantFiled: July 23, 1996Date of Patent: September 29, 1998Assignee: Continental Plastic Containers, Inc.Inventor: Gregory M. Fehn
