Application filedDccember 29,1925, Serial No. 78,134. Renewed April 12, 1928.

Thisinventionrelates to culinary packages and has for an object to provide anew and improved package or bag for containing a commodity tobe, employed in the bag,

5 as for instance tea.

A further object of theinvention is to provide a bag with means for sliding expansion under the swelling of contained material, as for instance the swelling of tea, when subjected to brewing process.

A further object of the invention is to provide a package of rolled fabric, one edge overlapping the other edge, to such a considerable distance as to permit sliding expan- IB sion Without spilling the contents, the outer edges being relatively non-stretchable and serving as a tension or retaining strip for the underlying stretchable edge.

lrVith these and other objects in view, the

an invention comprises certain novel features,

and elements as disclosed in the drawings together with mechanical and functional equivalents thereof as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a view in side elevation of the completed bag or package.

Figure 2 is a transverse sectional view through the package as indicated by line 22 of Figure 1.

Figure 3 is a view more or less diagrammatic showing the method of constructing the package.

Like characters of reference indicate corresponding parts throughout the several views.

The present invention comprises a package or bag for marketing a commodity which is used in the bag and the bag and used commodity then discarded, as for instance tea, which is representative of the class. The bag is constructed from a strip 10 of fabric material loosely woven which, according to the present practice, will be the material ordinarily referred to as cheese cloth, but it is to be understood that the invention is in no way limited to the particular weave or nomenclature of the fabric.

To understand the bag more completely, the

60 method of making will be described which consists in moving the strip of fabric 10 in the direction indicated by the arrow in Figure 3 by any approved means, manually or mechanically, and during such moving the commodity, as for instance the tea, is deposited upon the strip in spaced masses as indicated at- 11. This strip of material .10 will have one edge which is relatively nonstretchable and this may be previously supplied-to the strip i-n the manner well known in the art and referred to as selvage, but preferably this non-stretchable edge will be provided by means of over-seaming, indicated at 12, which is applied directly to the strip as it moves along by a properly positioned sewing machine, conventionally shown at 13. The edges of this strip 10 are drawn together and more or less rolled with the non-stretchable edge 12 outermost, overlapping the inner edge 13, shown at Figures 2 and 3, for such a considerable distance that the expansion of the material within this rolled and overlapped strip will not effect a separation of the edges for discharging the material contained. The edge 12 also serves as a tension so that the stress ordinarily applied to one or both edges of the completed bag tends to hold this nonstretchable edge in tension upon the under folded edge.

As the strip advances, the part intermediate the deposited masses of commodity are drawn together and constricted as indicated at 1 k in Figure 3, and bands 15 are placed or closed about said constricted portion, spaced apart. Before closing one of the bands 15, a string or cord 16 is slipped thereunder to which is previously or afterward attached a tag indicated conventionally at- 17 by which the commodity contained in the bag may be identified and which together with the cord 16 serves to handle the coin pleted bag shown at Figure 1. The completed bag is then severed from the advancing strip by a knife 18, mechanically or manually actuated, so that the constricted portion is severed intermediate the spaced bands 15 whereupon the bag is not only completed but severed and wholly independent from the strip as indicated.

It is obvious that the bag will normally be handled by the cord 16 which exerts pressure of the contained material thereon and serves to draw the non-stretchable edge 12 in taut relation over the under folded edge holding it against the contained pressure of the material, but nevertheless, when deposited in a receptacle for use and the tension released, permits the sliding of the inner edge by the outermost folded edge for expansion.

What I claim to be new is:

1. A culinary package comprising a fabric casing rolled about a commodity with i and overlapping the inner edge, said fabric being drawn together and constricted upon opposite sides of the contained commodity,

and a band around each of said constricted ends, the overlapping edge being relatively less stretchable and exerting tension upon the infolded edge.

3. A culinary package comprising a rolled strip of material, the outer edge being relatively non-stretchable and slidingly overlapping the inner edge and surrounding the contained commodity, said rolled fabric being constricted upon opposite sides of the commodity, and collars surrounding the con stricted part and retaining said constricted part in said condition, the overlapping edge forming a tension between the bands and upon the infolded edge.

In testimony whereof I aflix my signature.

,WALTER M. INGRAM.
