  • Patent number: 9021771
    Abstract: A vacuum and sealing appliance comprises a heat sealing element for sealing a container during a sealing cycle. A controller controls the temperature of the heat sealing element during the sealing cycle based on a signal from a temperature sensor that senses the real-time temperature of the heat sealing element. A seal indicator light is provided which is lighted during the sealing cycle and extinguished at its completion. The signal from the controller energizes the heating element for a time to heat the sealing element to a pre-determined temperature for sealing the container and initiates a dwell time corresponding to cooling the heating element after sealing the container. Values of the real-time temperatures of the heat sealing element and values of the sealing times and the dwell times that correspond to the values of the real-time temperatures of the heat sealing element are stored in a look-up table.

A plurality of petri dishes located adjacent one another are placed in an interior cavity of the pouch, after which the pouch is vacuum-packed, optionally flushed with an inert gas and then heat sealed. The placement and immobilization of the petri dishes in the pouch allow for prolonged shelf life and preservation of sterility, greatly reduced breakage rates, and enhanced visibility of the petri dishes by a user.

  • Patent number: 8240112
    Abstract: The evacuation device is configured to remove air from a container via a one-way valve element attached to the container. The evacuation device includes a motor with a rotating shaft that extends along an axis line. The shaft is operably interconnected to a reciprocating element reciprocally movable within a chamber along a direction parallel to the axis line. Reciprocal motion of the reciprocal element draws air into and exhausts air from the chamber. To facilitate the operable interconnection, the evacuation device includes a cam having a cylindrical sidewall mounted to the rotating shaft. Disposed circumferentially into the cylindrical sidewall is a channel. The evacuation device further includes a yoke connected to the reciprocal element and having a follower element received in the channel. Rotation of the cam causes the follower element to move with respect to the channel, thereby converting rotational motion to linear translation. The evacuation device may also include a pressure adjustment feature.
