Abstract (en)
The package consists of a backing (1), e.g. of plastic-coated card, and a covering layer (2) of a transparent plastic which is connected to the backing by a welded seam (2c). The seam contains a bubble (2d) filled with gas which is isolated from the outside and which, when opened, forms a tongue for opening the package along the seam. The bubble (2d) is dome-shaped and surrounded by two separate branches of the weld seam (2'c,2"d) and has a cut (2'd) made part-way through its surface on the outside of the bubble to facilitate opening. In a variant of the design a number of bubbles can be made at intervals round the weld seam.
Abstract (fr)
La feuille (2) est munie à proximité de son arête périphérique d'au moins une excroissance (2d) se dressant en saillie vers l'extérieur à partir du support (1) et délimitant un volume d'air isolé de l'extérieur, l'écrasement de cette excroissance (2d) provoquant sa déchirure et la création subséquente d'une patte de préhension permettant l'arrachage aisé de ladite feuille (2) par rapport au support (1). <IMAGE>
