Claim.

This invention relates to containers of the envelope type.

An object of this invention is to provide a container which is formed of superposed plies of corrugated paper with one edge of the container free and provided with one or more flaps engageable over the open end so as to close the same.

Another object of this invention is to provide a container which is formed by a series of rectangular plies secured together about three edges thereof, or by a pair of corrugated plies which are folded at one edge and secured together along two edges.

A further object of this invention is to provide a corrugated paper container which can be used for shipping or storage of articles heretofore shipped in corrugated containers or any other similar type of package.

With the above and other objects in view, my invention consists in the arrangement, combination and details of construction disclosed in the drawings and specification, and then more particularly pointed out in the appended claim.

In the drawings:

Fig. 1 is a plan view partly broken away of a container or envelope constructed according to an embodiment of this invention.

Figure 2 is a fragmentary side elevation of the envelope with the upper end thereof sealed.

Figure 3 is a sectional view partly broken away taken on the line 3—3 of Figure 2.

Figure 4 is a fragmentary sectional view taken on the line 4—4 of Figure 1.

Figure 5 is a fragmentary sectional view taken on the line 5—5 of Figure 1.

Figure 6 is a plan view of a modified form of this invention.

Figure 7 is a sectional view partly broken away taken on the line 7—7 of Figure 6.

Figure 8 is a plan view of another modification of this invention.

Figure 9 is a sectional view partly broken away taken on the line 9—9 of Figure 8.

Referring to the drawings and first to Figures 1 to 5 inclusive, the numeral 19 designates generally an envelope which is formed of an outer pair of corrugated plies II and 12 which have disposed therebetween an inner pair of plies 13 and (4.

The plies i ί to 14 inclusive, are formed of corrugated board and the marginal portions of the several plies are secured together by longitudinal stitching (5 and a bottom stitching 15. The upper end of the envelope 10 is initially open and an inner closure flap Π extends from the upper (Cl. 229—68) end of outer ply 12 and is formed with upwardly convergent end edges 18. The inner flap (7 is adapted, when in closed position, to be extended over the upper ends of plies 12, 14 and 13 and 5 to be inserted between plies 1 i and 13, as shown in Figure 3.

An outer sealing, flap 19 is formed as an extension of ply or wall 11 and is adapted to be extended over the upper ends of all of the plies, as 10 shown in Figure 3, and to overlap the outer ply 12. An adhesive tape 20 is adapted to be extended horizontally across the flap 19 and the ply or wall 12 so that the envelope will be thoroughly sealed.

Referring now to Figure 6, there is disclosed another modification of this invention embodying an envelope generally designated as 21 which is formed of a pair of outer corrugated plies 22 and 23 which are integral with each 2o other, as indicated by the bend or fold 24 along the longitudinal edges of these plies. An inner pair of plies 25 and 26 is disposed between the outer plies 22 and 23, and the inner .plies 25 and 26 are also formed integral with each other along 25 the longitudinal fold line 27 which is disposed within the longitudinal fold 24 of the outer plies 22 and 23.

The pair of outer plies 22, 23 are adapted to be secured together by means of a longitudinal line 30 of stitching 28 and a lower line of stitching 29. The upper end of the envelope is provided with a tapered inner flap 30 similar to flap 17 and is also formed with an outer flap 3 ί similar to flap 19.

₃₅ Referring now to Figures 8 and 9, there is disclosed another modification of this invention embodying an integral outer pair of corrugated plies 32 and 33 which are connected together by a bottom integral bend or fold 34. An inner pair of 40 corrugated plies 35 and 36 is disposed within the outer plies 32 and 33, and the inner plies 35 and 36 are connected together by an integral bend or fold 37. A closure flap 38 extends from outer Ply 32 and is adapted to be extended over the upper ends of the outer and inner plies, as shown in dotted lines indicated by the numeral 39 in Figure 9.

The lower edge of the flap 38 when in envelope closing position may be secured by means of an 50 adhesive on the inner face of the flap 38 or by means of an adhesive tape similar to tape 20.

The envelopes hereinbefore described provide a container for receiving various types of articles which have heretofore been packaged in standard 55 types of containers or any other types of pack2,689,079 aging, materials These articles may be machine parts, hardware, glass or plastic objects, textile products, paper and paper products and the like, including household articles, instruments, mechanical assemblies and various other types of 6 articles which can be carried in this container. The provision of the corrugated plies of material will form a cushioning means for the walls of the container so that the article or articles disposed between the inner pair of plies or between the io outer and inner plies will be protected against bending or other injury during the packing or shipment thereof.

I do not mean to confine myself to the exact details of construction herein disclosed, but claim 15 all variations falling within the purview of the appended claim.
