  • Patent number: 4528694
    Abstract: A carry-bag includes two wall sheets (34,36) joined or coherent to define a bag portion, and the respective top portions of the wall sheets are provided with gripping and carrying openings. In order to provide a strong, easy to use, and relatively tight closing to the interior of the bag portion, the top portion of a first wall sheet (34) has been folded inwardly and attached to define an insertion pocket (24), and a gripping opening is provided in the pocket. A top portion of the other wall sheet (36) is shaped as an insertion tongue (32) which is also provided with a gripping opening (6) and is adapted to be received in the interior of the pocket (24) so that the two gripping openings are at least partially coextensive.

  • Patent number: 4211267
    Abstract: A thermal insulating and shock absorbant bag, particularly a carrying bag, is formed of walls each having an outer layer of thin, flexible thermoplastic foam of a thickness between the 0.07 mm and 0.14 mm, which provides effective insulating properties. The bag walls each have an inner layer of thin flexible thermoplastic polyethylene film connected by welding to the outer layer at the edge portions of the bag. The inner layer may be formed of two films of polyethylene film with an intermediate film of metal foil located therebetween and steam-connected to one of said polyethylene films. In a preferred embodiment, a flexible insulating layer of padded polyester cotton is disposed between the inner and outer layers to improve the insulating and shock absorbing qualities of the bag. The insulating layer is thermoplastic and is welded to the surrounding layers.
