Abstract
An improved package for storage and/or shipment of flexible materials which is particularly applicable to packaging a plurality of flexible magnetic disks such as flexible disks. Flexible disks are uniformly aligned and sealed within a heat sealable, heat shrinkable plastic bag. A hole is placed in an edge of the bag for tight draw down, and the bag is heat shrunk. Enhanced protection is afforded by placing and forming a second heat shrunk plastic bag around the first. A foam collar is firmly positioned about the peripheral edge of the package to provide edge protection to the package during shipment. The improved package prevents physical damage to the individual flexible disks from handling, shipping impact and particulate contamination.
Claims19
An improved package adapted for a plurality of thin flexible materials of substantially identical geometry, the package comprising:
- a first and a second substantially rigid plate of length and width dimensions substantially identical to that of a plurality of thin flexible materials to be packaged;
- and
- a heat shrinkable material having a hole therein to provide an air escape path suitably heat sealed and heat contracted so as to snugly contain said thin flexible materials therewithin with said thin flexible materials being aligned uniformly on top of one another in a stack with said first substantially rigid plate aligned on top of said stack and with said second substantially rigid plate aligned on the bottom of said stack so that the total thickness of said stack is less than the longest dimension of said thin flexible materials.
An improved package for a plurality of thin flexible materials of substantially identical geometry aligned uniformly on top of one another with their thickness dimension much less than their respective length and width dimensions, comprising:
- first and second substantially rigid plates having length and width dimensions substantially similar to the respective length and width dimensions of said thin flexible materials located on the top and bottom of said uniformly aligned thin flexible materials so that the thickness of the plurality of said thin flexible materials plus said first and second plates is less than the longest dimension of said thin flexible materials;
- the heat shrinkable material formed substantially into the shape of the peripheral edge of said uniformly aligned thin flexible materials with said first and second substantially rigid plates located on the top and bottom thereof with said edge sealing means adapted to snugly fit over said thin flexible materials with said first and second substantially rigid plates located on the top and bottom thereof so as to hold said thin flexible materials and said first and second substantially rigid plates preventing relative motion between said thin flexible materials and between said thin flexible materials and said first and second substantially rigid plates.
A method for manufacturing an improved package for a plurality of thin flexible materials of substantially identical geometry with their thickness dimensions much less than their respective length and width dimensions, comprising the steps of:
- (a) assembly of said plurality of thin flexible materials into a stack with each item of thin flexible material uniformly aligned on top of its adjacent item of thin flexible material;
- (b) placement thereafter of said uniformly aligned stack of thin flexible materials into a means for wrapping formed into the shape of a bag adapted to receive said uniformly aligned stack of thin flexible materials wherein said means for wrapping is constructed of a heat shrinkable material with a small hole located along one peripheral edge;
- (c) thereafter heat shrinking of said means for wrapping to form a first heat shrunk wrapping about said stack;
- and
- (d) placement of a collar around said heat shrunk wrapping wherein said collar is constructed of a resilient material adapted to snugly fit over the periphery of said heat shrunk wrapping so as to lightly compress said heat shrunk means for wrapping.
A method for manufacturing an improved package for a plurality of thin flexible materials of substantially identical geometry with their thickness dimension much less than their respective length and width dimensions, comprising the steps of:
- (a) assembly of said plurality of thin flexible materials into a stack with each item of thin flexible material uniformly aligned on top of its adjacent item of thin flexible material;
- (b) placement thereafter of said uniformly aligned stack of thin flexible materials between a first and a second substantially rigid plate with length and width dimensions substantially similar to said thin flexible materials so that said first plate and said second plate sandwich said stack of thin flexible materials therebetween;
- (c) placement thereafter of the uniformly aligned stack of thin flexible materials between said first and second plates into an edge sealing means formed into the shape of the peripheral edge of the assembly out of a heat shrinkable material;
- (d) heat shrinking of said edge sealing means;
- (e) placement of a collar around said heat shrunk edge sealing means formed from a resilient material so as to lightly compress the peripheral edge.
