BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The present invention relates to an inner packaging for abdominal towels sterile-packed in an outer packaging.
Abdominal or surgical towels or surgical compresses are used in surgical operations to dry-up blood and other fluids and to halt the flow of blood in surgical wounds. The abdominal towels are sterile-packed in bundles in an inner packaging which, in turn, is enclosed hermetically in a sterility-maintaining outer packaging. In surgical operations, the outer packaging is opened by a non-sterilized attendant nurse such that a sterilized working nurse is able to remove the inner packaging without touching the non-sterile outer packaging.
Several different types of inner packaging for abdominal towels are known to the art. A first type is comprised of a paper bag which is opened by tearing the bag, and a second type is comprised of composite packaging material comprised of a paper sheet and a plastic sheet that are joined together by a peripheral seam or join while leaving gripping flaps. Both of these packaging types have the drawback of needing two hands to open the packages. A third type is comprised of a paper sheet which is folded in a way to form a closed package by the actual folding procedure. Because of the complicated folding procedure entailed, this type of packaging is not suited for mechanical manufacture and requires a great deal of material in the making. Furthermore, this type of packaging is often difficult to open with one hand.


SUMMARY OF THE INVENTION

The object of the present invention is to provide an easily opened inner packaging for abdominal towels which can be produced easily and cheaply and which is not encumbered with the drawbacks of known inner packagings.
This object is achieved in accordance with the invention by means of an inner packaging for abdominal towels sterile-packed in an outer packaging, characterized in that the inner packaging is comprised of an essentially rectangular sheet of material having pairs of mutually opposing first and second edges which are folded around a bundle of abdominal towels placed on the sheet in a manner such that a first part of the sheet that includes one of the first edges covers a substantial part of the abdominal towels and a second part of the sheet that includes the other of said first edges covers a section of the inwardly folded first sheet part, and such that those sections of each edge in the pair of second edges and included in the first and the second inwardly folded sheet parts lie essentially in line with remaining sections of the second edges concerned; and in that the inner packaging is closed solely by two mutually opposing joins which extend generally parallel with the second edges of the sheet and connect the end-parts of the inwardly folded sheet-parts and the opposing end-parts of that part of the sheet which includes the sections of the second edges folded onto the folded sections of the second edges, the end-parts containing the inwardly sections of the second edges are mutually joined by means of an easily opened fastening. Packaging of this kind can be easily produced mechanically in a cost-effective manner and can also be easily opened with one hand.
In a preferred embodiment, the sheet is made of paper and said fastening being comprised of a mechanical fastening obtained by embossing the edge-parts that include the second edges.
In another variant, the readily opened fastening is a glue joint.
In a second embodiment, at least the inwardly folded second part of the sheet is perforated at its end-parts containing the second edges along lines which extend parallel with the joins and which are further remote from the outer ends of the end-parts than said joins.
