Abstract

Abstract Battery packaging construction for batteries of flat configuration which includes a first layer of heat sealable plastic coated metal foil. A battery on top of the first layer with a second layer of heat sealable plastic coated metal foil on top of and facing the battery which plastic layers are heat sealed under vacuum. An optional frame may surround the battery on top of the second layer, which frame is adhesively secured to the second layer, filler material is placed around the frame and the foil and cured by ultra violet light or electron beam, a third layer is adhesively secured to the frame and a label layer is placed on the third layer. Terminals of flat metal foil extend from the battery out between the first and second foil layers over and under the base and are secured to the bottom layer. An elongated base plate may optionally be provided which has the layer of adhesively secured foil on the bottom, and the first layer of adhesively secured foil on the top surface of the base.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 103 words
Battery packaging construction for packaging of flat alkaline metal or alkaline earth metal batteries which comprises a first layer of metal foil having top and bottom surfaces, said first layer having a layer of heat sealable plastic on its top surface, a battery on said layer of heat sealable plastic, a second layer of metal foil on and extending over said battery, a heat sealable plastic layer on said second layer which faces and is in contact with said battery and said heat sealable layer on said first layer whereby said plastic layers can be heat sealed to enclose and contain said battery.
Claim 2
Dependent Claim 103 words
Battery packaging construction for packaging of flat alkaline metal or alkaline earth metal batteries which comprises a first layer of metal foil having top and bottom surfaces, said first layer having a layer of heat sealable plastic on its top surface, a battery on said layer of heat sealable plastic, a second layer of metal foil on and extending over said battery, a heat sealable plastic layer on said second layer which faces and is in contact with said battery and said heat sealable layer on said first layer whereby said plastic layers can be heat sealed to enclose and contain said battery.
Claim 3
Dependent Claim 45 words
