DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a carry-bag comprising two wall sheets which are joined together and/or are coherent along two opposed side edges and along a bottom edge so as to define a bag portion, the top portions of said wall sheets being provided with respective gripping and carrying openings.
Carry-bags of this type including hand grip apertures in the top portion thereof are known in several designs. There is, however, a need for a carry-bag having a simple closing arrangement, whereby the top of the bag can be closed so that goods in the interior of the bag can be effectively and relatively tightly confined therein. This need is particularly outstanding in connection with so-called thermo carry-bags e.g. for storing and transporting frozen products.
It is an object of the invention to satisfy this need by providing a carry-bag of the actual type having a carrying and closing arrangement which is sturdy, simple to use and to manufacture and whereby the access to the interior of the carry-bag can be effectively and relatively tightly closed.
This is achieved by the carry-bag of the invention which is characterized in that the top portion of one of the wall sheets is folded inwardly and backwardly and is attached so as to define an insertion pocket, the entry of said pocket being at the inner side of said wall sheet, when the carry-bag is in its open condition, a first gripping opening being defined in the insertion pocket thus provided, and in that the top portion of the other wall sheet is shaped as an insertion flap provided with a second gripping opening and adapted for introduction into the interior of said insertion pocket so that said first and second gripping openings are at least partially coextensive with said insertion flap received in said pocket.
When grasping and lifting the carry-bag in its closed condition, i.e. with the insertion flap introduced into the corresponding insertion pocket, by putting the fingers of a hand through the respective gripping openings, the leading or top edge of the insertion flap will be pulled into or up into the insertion pocket, thereby tightening against the bottom of the pocket. In a preferred embodiment, this tightening effect is further improved by providing the top edge of the insertion flap with a passage or channel which includes or is adapted to receive a transverse carrying stick in the area along the top edge of the flap. Such a carrying stick also renders the bag sturdier and more comfortable to carry in the hand.
The gripping openings in the insertion flap and in the insertion pocket, respectively, may be designed as usual hand gripping apertures which are at least partially coextensive in the closed condition of the carry-bag. In a particularly preferred embodiment, the gripping opening in the insertion pocket is, however, defined by a U-shaped cut provided in the wall sheet before the formation of the pocket by folding the wall-sheet, and wherein the bottom of the U-shaped cut extends along and spaced from the top edge of the unfolded wall sheet. A subsequent formation of the insertion pocket by folding across the two legs of the U-cut will thereby provide a closing flap having a free edge which can be adapted to be threaded through the gripping opening in the insertion flap in the closed condition of the carry-bag, whereafter the closing flap can be detachably connected with the outer surface of the carry-bag, e.g. by means of a snap fastener. Thus, in this embodiment, the gripping opening in the insertion pocket defines a notch in the bottom of the completed pocket, whereby the gripping opening of the insertion flap will be exposed completely or partially in the closed condition of the carry-bag. The tightness in the closing of the bag is, however, further improved due to the fact that the closing flap tends to prevent the insertion pocket from opening and also due to the fact that the closing flap forms a flap-over closure.
Preferably, the top portions of the two walls sheets have been doubled by foldings before providing the insertion fl
