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.
