  • Patent number: 5456379
    Abstract: A re-usable tray for securely containing both small and large perishable goods, while providing a unique means for ventilating and circulating fluids is described. The ventilating means efficiently permits the transfer of fluids between the interior and exterior of the tray. The tray may be combined with a cover to form a container. The container may contain blueberries and other small perishable goods, wherein the ventilating means is not blocked by these goods. Further, the ventilating means provides for drainage to minimize condensation build up. The container also has ribs extending from the sides, front and back of the container providing rigidity and support to the container. The ribs have slits that provide additional ventilation to the container. The container also has a support means for preventing the top and bottom of the container from bending or curving into the interior storage area of the container.

  • Patent number: 4917421
    Abstract: A readily detachable fastener for mounting upon an enclosure, the fastener having a base member with channeled edge portions designed to slidably engage the enclosure upon which it is mounted. A connector pin extends outwardly from the base member, and is designed to releasably lock into a pin receiving hole of the enclosure such that the detachable fastener may be attached or removed from the enclosure, as desired. A latch is pivotally connected to the base member, and carries a bail which catches on the cover of the enclosure when the latch is pivoted to an open position. The latch may then be pivoted to a closed position, thereby tightly securing the cover to the enclosure. The base member and latch are constructed with openings therethrough so as to accommodate locking the same together with a conventional lock.
