A battery-powered apparatus, for inducing air flow past a product capable of being vaporized, includes a compact housing that comprises a hollow outer shell and a hollow, generally cylindrical inner shell, having an axis, on which the operating components of the apparatus are supported. The inner shell is mounted with the outer shell by a hinge to pivot substantially on the axis between closed and open positions. In the closed position the inner shell compliments the outer shell to define an enclosed space and shield the apparatus components. In the open position, the inner shell is nested within the outer shell to expose the apparatus components. The product and a battery for powering the apparatus may be assembled into a cartridge formed to be received in the apparatus housing. Electrical battery contacts and a support for the cartridge in the housing are also disclosed.

A locking assembly for application to the front door of an upright refrigerator, having magnetic means for yieldably retaining the door in closed position, which includes an elongated locking member having an elongated pivot slot in one end thereof and a locking hook on the other. The assembly also includes a pair of substantially identical pivot and keeper members, both adapted for adhesive securement, the pivot member to the refrigerator and the keeper member to the door. The pivot member extends through the slot in the locking member, while the hook on the latter is engageable with the keeper member.

A device for releasing a volatile substance into the environment in a controlled manner comprises a reservoir of substance-absorbent material, for storing the substance, that is encapsulated in an envelope, at least a portion of which comprises a permeable material having porosity at least equal to ultramicroporosity. The permeable envelope portion has a greater affinity for the substance than does the reservoir material. The remainder of the envelope comprises a material impermeable to the substance. Accordingly, the substance permeates through the permeable envelope portion to be released therefrom in vapor form into the environment.

A method of making a product, which holds and dispenses a volatile substance, comprises the steps of advancing a backing material, a reservoir material and a third material, that is permeable to the volatile substance, from respective supplies into close proximity to each other with the reservoir material lying between the backing and permeable materials. The volatile substance is then supplied to the reservoir material to be absorbed thereby. The three materials are fused together in a pattern defining a closed loop periphery to seal the reservoir material between the backing and reservoir materials at the periphery and thereby form the product.
