Description of the utility model application

from Supracolor Finanz AG, Spielhof 16, CH-875O Glarus

concerning:
"Paper bag"

The innovation relates to a flat paper bag which can be closed after the edges delimiting its opening have been folded over is. Such bags are used for the bulk mailing of objects of the same shape, such as samples, films and the like. Bags of this type that have been customary up to now are closed after a single or, better still, twice By folding over the neck of the bag, the bead formed in this way is perforated - it can also be done during the manufacture of the bag Perforation can be made - and then the closure is secured by an inserted metal clip.

This type of closing is disadvantageous because you have to keep separately to be stored clasps in stock; the agraffes can fall out again, and there is also a certain risk of injury from their sharp edges.

It goes without saying that you can use an adhesive tape instead of the clasp, but manipulating it is a lot more laborious than when using metallic brackets.

The task of the innovation is to create a paper bag of the type mentioned, in which all for the closure

required elements are already present on the bag, but without the bag in terms of its storage and possibly machine filling would be affected in any way.

The solution to this problem results from the protection claim 1, while the subclaims expedient refinements of the same define.

The term "contact adhesive" is to be understood as meaning those that have an associated second adhesive layer enter into an adhesive bond, but not with other materials. Such contact adhesive can be used for both permanent lock (mailing of letters) and also for locks that can be reopened several times (printed matter, samples) will.

The same contact adhesive has already been used on ordinary envelopes. But there are special ones, the mechanical ones Provide processing aggravating folds so that this is not unintentional the envelope is sealed or more than one envelope is stuck together. This restriction does not apply to the bag according to the innovation. Namely, if no fold has been made, and this is always done immediately before the When closed, the pouches lie completely flat, and because the two strips are offset in height, they can also be placed in magazines and the like are stacked in the same direction without mutual sticking occurring.

A sample in which the features of all protection claims are implemented is attached here; the strips are set off against the bag paper material by a colored marking and thus made recognizable.
