Abstract

Abstract A heat sealed package for soap powder, stored therein as a layer, and prevented from shifting therefrom into a concentrated mass by compartment-delineating additional heat seals. Said additional heat seals are intentionally provided in spanning relation across the package with a small length portion unsealed, so that a passage is provided in said unsealed portion for any trapped air to displace to another location under an external pressure, rather than contribute to rupturing the package.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 301 words
A rupture-proof package formed of paper construction material for soap powder comprising a cooperating pair of front and rear rectangular panels presenting opposite long and short dimensioned sides arranged in superposed relation and having heat sealable surfaces in facing relation to each other, a rectangular peripherally applied heat seal for joining said front and rear panels to each other so as to bound therebetween a correspondingly rectangularly shaped storage compartment for a layer of soap powder having an operative interposed position therebetween prior to the application of said peripheral heat seal, and five position-retaining heat seals additionally joining said front and rear panels to each other applied in spaced apart relation along said long dimension of said package so as to correspondingly delineate said compartment into six sub-compartments each oriented lengthwise in said short dimension thereof to thereby minimize the shifting concentration of said stored layer of powder within said compartment, each said position-retaining heat seal extending in spanning relation between an opposing pair of said long dimensioned peripheral heat seals only for most but not all of the distance therebetween to thereby form at least one communicating air passage extending in the long dimension of said package between said sub-compartments in the unsealed distance left between said position-retaining heat seals and said peripheral heat seal in adjacent position thereto, whereby any external pressure applied against any air trapped in said package during the sealed enclosure of said soap powder is merely displaced to another location rather than contributing to the rupture of said package and any select number of less than said six sub-compartments are adapted to be opened for removal of the contents therefrom by merely severing said package in said long dimension thereof in said unsealed distance and for an extent corresponding to said select number of sub-compartments.
