  • Patent number: 5152416
    Abstract: A plastic container and lid both of resilient material with the container having spaced thread segments below its upper edge and the lid having a central section from which extends an outer sealing section with a curved upwardly sloping inner wall and thread segments on the inside of a skirt wall extending downwardly from the sealing section. Threading of the lid onto the container in a downward direction brings the inner periphery of the container upper edge into an increased contact with the lid sealing section curved upwardly sloping inner wall and the latter also exerts an outward radial force on the container wall to enhance the sealing action and which also tightens the engagement between the lid skirt and container wall in the areas of their mating threads.

  • Patent number: 4766519
    Abstract: A housing or enclosure, which is particularly suitable for electronic circuits, comprises two housing parts that fit together and interlock. Each housing part is substantially U-shaped in cross-section and has an end cover that covers the total cross-section of the closed housing. The opposing interfacing surfaces of the longitudinal edges of the housing are profiled in the longitudinal direction, enabling the two housing parts to be fitted together in the transverse direction to the longitudinal axis of the housing, and at the same time serving as guiding rails to allow the housing parts to slide against one another in the longitudinal direction of the housing. This housing construction permits the housing to be assembled easily and permits the length of the housing to be varied in a simple manner.

  • Patent number: 4530442
    Abstract: A plastic sealing ring is attached to a rim of a plastic container with an insert interposed between the rim and the sealing ring. By making the insert from a relatively rigid material, the insert can rigidify the sealing ring and hence the container. If the insert is made from an electrically conductive material, the insert can function to facilitate the induction welding of the sealing ring to the container. The sealing ring and insert can be formed as a unitary, composite sealing ring subassembly adapted for direct application to the rim of the container or they can be supplied as individual parts adapted to be applied to the rim of the container separately. In order to form the sealing ring subassembly, the sealing ring is molded from molten plastic. During the cooling of the sealing ring, the insert is positioned in a groove formed in the sealing ring.

    Abstract: A cooking pan assembly is provided which has particular utility in the industrial cooking of food, such as tuna fish. The cooking pan is particularly constructed so that it may conveniently be transported on usual conveyors within the cooking facility. Crimped wire-formed ends are provided for the pan which serve as handles and which prevent the contents of the pan from sliding through the front or rear ends thereof. The wire-formed ends are crimped loosely to the side walls and bottom of the pan for sanitary reasons so that there is only a point contact between the wire-formed ends and the sides and bottoms, and no areas are formed which would be conducive to build up of bacteria. There are no welds between the end members and the bottom or side walls of the pan, since such welds would produce two separate surfaces in intimate contact with one another which could harbor bacteria. The pan assembly is easy to clean thoroughly by a simple spray wash since there are no nooks or crannies in the assembly.
