Claims priority, application Great Britain February 26, 1954 1 Claim. (Cl. ISO-2.1)
The present invention relates to envelope-like containers, particularly containers of textile or similar material or fabric for the holding of pads, dressings or the like. The invention is primarily concerned with such containers for heat-generating pads for securing them to parts of the body for the application of local heat, although they may be used for other purposes.
According to this invention, the envelope is made of a suitable fabric and has tapes for tying to a limb or other part of the body, each said tape passing into the container or envelope at opposite sides thereof, and being fixed such as by stitching to one wall of said container where it is Within same.
Conveniently, the container is made from a length of fabric which is folded on itself to provide the two walls, the sides being joined by stitching or other means.
The invention also consists of an envelope for containing a pad, comprising a length of fabric folded and stitched to form a pocket-like envelope, and a tape for tying to a limb of the body said tape passing into the envelope from opposite sides thereof, and means for fixing the tape to one wall of the envelope within same.
The envelope conveniently has a tuck-in or other flap, and to assist in the release of heat and water vapour which may be given off, the pad is perforated, for example, by providing a series of punch holes therethrough.
Reference will now be made to the accompanying drawings showing a preferred form of container or bag made in accordance with the invention, and in which:
Figure 1 is a view of same after stitching, and
Figure 2 is a view after turning inside out with respect to Figure 1, but in the normal position of use.
2,773,531 i atented Dec. 11, 1956 "ice Referring to the drawings, the envelope or bag is made from a length of rubberized fabric folded on itself to provide walls 1a, 1b. The first step in manufacture before the length is folded on the transverse line 2 and the sides stitched up is the stitching on of the two tapes 3, 3. These are stitched by their median parts 3a shown lying on the wall 1a by a line of stitches 4, which, as shown, passes along one tape from one end to the other, along the side adjacent the edge and then along the other tape. If more than two tapes are provided the stitches will be continued along the other side to the next tape so that the stitch line is zig-zag. Thus, the tapes are fixed to the wall 1a.
The free lengths of tape can then be folded in beneath the wall In, and the length folded, the side edges being stitched up by the stitches 5, 5. The wall 1b is longer than the wall 10, and is shaped to provide the tuck in flap 6.
Holes 7 are punched through the walls to allow for the escape of Water vapour when the bag is used for containing a heat-producing pad.
Figure 2 shows the bag in its normal position for containing a pad. The free tape parts extend from the sides, and the bag can be secured to a limb by using same. There is little strain on the fabric owing to the manner of stitching the tape thereto, with the tapes passing out between the walls.
The flap could be fastened by press studs or like fasteners.
An envelope for a pad, said envelope being made from fabric and having tapes for tying to a limb or other part of the body, each tape passing into the container at opposite sides thereof and being fixed such as by stitching to one wall of said container where it is within same.
