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.

Abstract: In the embodiment of a redemption coupon in a magazine or other bound publications, there are inconveniences if the coupon is physically removed from a page of the magazine, since the remaining partial page is difficult to turn, text is also inadvertently removed, etc. Thus, it is desirable that the coupon be removable with effect on its adjacent magazine pages thus dictating that there be no physical connection between it and the magazine pages. On the other hand, handling of a small coupon-size panel during preparation of the magazine has obvious shortcomings. As a solution to the foregoing, the within method contemplates the use of a physically attached coupon and page, and subsequent folding thereof so that the "physical attachment" therebetween is advantageously presented to the cutting blade used in the conventional edge-trimming step in the preparation of the magazine, and is thus removed during this step, thereby providing the desired separable redemption coupon for the magazine.
