  • Patent number: 5934773
    Abstract: A humidifier device including at least two housings, each housing containing an absorbent material. Each housing is designed as a stamped or molded cup-shaped member having rounded corners and a flanged edge, and a plurality of apertures. A flat, rectangular member is attached to the flanged edge, thereby creating a cavity between the flat, rectangular member and the cup-shaped member. The absorbent material is located within the cavity and is soaked with an evaporative solution for imparting moisture into the storage case by evaporation through the apertures in the housing. The humidifier device may be replenished by pouring solution through the apertures on the housings, or by immersing humidifier device in a bath of solution, thereby allowing the absorbent material to become replenished with solution. The housings are each provided with a magnet attached to the flat, rectangular member which can be used to mount the housing to a second magnet mounted on the interior of the storage case.

  • Patent number: 4143785
    Abstract: A plastic cap for vacuum sealing glass containers such as bottles or jars is disclosed. The cap includes a top wall and a depending annular side wall which extends over and is adapted to be threadedly secured to the neck of a container. The depending side wall has at its lower edge a lead-in chamfer and suitable threads adapted to engage corresponding threads formed on the exterior of the container to which it is to be secured. In a preferred form, serrations are provided on the exterior surface of the cap for gripping purposes, and a reinforcement shoulder is located on the outer perimeter of the side wall adjacent the lower edge thereof to prevent excessive cap expansion upon application to a container. Vacuum sealing is attained by means of two annular flanges depending from and integrally formed with the top wall of the cap.
