Abstract
Various embodiments of a press-to-open zipper for reclosable packages are disclosed. In a first embodiment, extensions are formed obliquely on the consumer side the zipper profiles and are squeezed together to separate the zipper profiles and open the package. In a second embodiment, arched portions are formed on the product side of the zipper profile. These arched portions are squeezed together to separate the zipper profiles and open the package. In a third embodiment, one of the zipper profiles includes a rounded portion with a semi-circular cross section upon which interlocking elements are formed. By squeezing together the zipper profiles by the edges thereof, the profiles rotate with respect to each other about the rounded portion so as to release the interlocking of the interlocking elements and open the package.
