DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a plastic bag for personal-hygiene articles, in particular for a stack of make-up removal pads, consisting of a sheet-plastic tube forming an essentially cylindrical bag wall, both of whose ends are closed, a suspension string for the bag being located at the upper end and an opening allowing pads to be removed being located preferably near the lower end.
BACKGROUND ART
A plastic bag of the generic type is known for instance from German utility model specification 17 43 587, according to which a sheet-plastic tube is provided to form a substantially cylindrical bag wall, the lower end of the sheet-plastic tube being tightly closed by corresponding doubling of the bag wall and electronic sewing of the doubled portions. Preferably, this end can be provided with an opening allowing removal in the form of prepunched perforated lines.
The other end to be opened of the known plastic bag, for instance the upper end, is provided with a bag suspension string passing through a channel formed by the edge of the tube being doubled down and welded.
This known plastic bag is disadvantageous in as much as the channel accommodating the suspension string is rather complicated to manufacture. Moreover, tightening the string will regularly produce a central hole as a result of the plastic sheet gathering, this hole opposing as hermetic as possible a closure of the plastic bag. Further, consumers will tend to open the plastic bag at the upper end by undoing the knot and the gathering, instead of using--as provided--the lower opening allowing removal.
SUMMARY OF THE INVENTION
Proceeding from the specified prior art disadvantages, it is the object of the invention to improve a plastic bag of the generic type such that, while being tight, the closing of the bag is as easy as possible and the suspension string is easy to apply.
Accordingly, the closure at the upper end of the plastic bag is formed by a linear seam running between the two diametrically opposite points on the wall of the bag through the longitudinal axis of the bag, the suspension string passing through the bag below the seam. In this construction, it is of advantage that only a single transverse seam is used, any complicated doubling of the edge of the bag and placing of the suspension string into a channel being avoided. Moreover, the plastic bag is closed except for the inlet and outlet of the suspension string, there being however the possibility to dimension these two passages such that they closely surround the suspension string, the bag virtually being tightly closed.
With the suspension string in parallel to the seam, the latter works as an additional reinforcement, any tearing of the bag material being prevented even if the suspension string is pulled vehemently. This is of advantage in particular when the plastic bag is gathered in the vicinity of the seam by means of the suspension string and when this gathering is fixed by the suspension string being knotted outside the plastic bag. Embodied like this, the plastic bag moreover gives the impression of a prior art bag so that there is no change in the appearance that consumers have become familiar with.
Further features, details and advantages of the invention will become apparent from the ensuing description of an exemplary embodiment, taken in conjunction with the drawing, in which

DESCRIPTION OF THE PREFERRED EMBODIMENT
A plastic bag according to the invention is made from a substantially rectangular sheet-plastic blank, which with the aid of a longitudinal weld, is converted into a sheet-plastic tube forming an essentially cylindrical bag wall 3. At its lower end 4, the sheet-plastic tube is closed in a fashion not shown in detail by lapping sections being doubled down and welded. The resulting bot
