Abstract

A package for batteries which comprises a header board and a heat-shrunk thermoplastic film holding the batteries relative to the header board. The header board has a vertical wall and a skirt integrally extending downwardly from the lower end of the vertical wall and covering a portion of the battery. The thermoplastic film covers the skirt and the batteries.

Claims

1. In a battery package of the type including a plurality of cylindrical batteries, each having opposite circular ends, each said battery having at a first circular end thereof a terminal projection, said batteries being juxtaposed such that all of said terminal projections extend in the same direction, the improvement wherein said package further comprises:

a header board formed of a single sheet of board, said board having opposite first and second end edges equally spaced from a center line, and first and second intermediate lines, each said intermediate line being spaced by an equal distance from said center line on opposite sides thereof, such that first and second symmetrical intermediate board portions are formed between said center line and said first and second intermediate lines, respectively, and first and second symmetrical skirt board portions are formed between said first end edge and said first intermediate line and between said second end edge and said second intermediate line, respectively;

said single sheet of board being folded along said cetner line such that said first and second intermediate board portions are in mutual abutting contact to form a wall, said single sheet of board being folded at said first and second intermediate lines such that said first and second skirt board portions extend outwardly from opposite sides of said wall to form a skirt, said skirt having an elliptical configuration when viewed from a direction along said wall and perpendicular to said center line;

said header board being positioned with said skirt covering said first circular ends and said terminal projections of all of said batteries, with said skirt board portions being inclined relative to said first circular ends of said batteries, said inclined skirt board portions defining therebetween a free space within which said terminal projections are completely enclosed; and

a heat-shrunk thermoplastic film covering the outer exposed cylindrical surfaces of said batteries and said skirt, said film holding said header board to said batteries in a position such that said terminal projections are completely covered by said skirt.

2. The improvement claimed in claim 1, wherein said first and second intermediate board portions of said wall have aligned holes therein, through which a hanger pin is adapted to be loosely fitted.

3. The improvement claimed in claim 1, wherein said thermoplastic film is transparent.

4. The improvement claimed in claim 1, wherein said thermoplastic film has therethrough a series of small perforations extending substantially parallel to the line of contact between adjacent said batteries.

5. The improvement claimed in claim 1, wherein the portion of said heat-shrunk thermoplastic film opposite said header board covers second circular ends of said batteries.
