(Cl. 22S- 68) 1 claim. l
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 rec-A tangular 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-li of Figure l.
Figure 5 is a fragmentary sectional view taken on the line 5 5 of Figure 1.
Figure 6 is a plan view of a modied form of this invention.
Figure 7 is .a sectional View partly broken away taken on the line 'I--l of Figure 6.
Figure 8 is a plan View of another modication of this invention.
Figure 9 is a sectional view partly broken away taken on the line 9-9 of Figure 8.
ReferringI to the drawings and iirstv to Figures l to 5 inclusive, the numeral I0 designates generally an envelope which is formed of an outer 4pair of corrugated plies Il and I2 which have disposed therebetween an inner pair of plies I3 and I The plies I I to iii inclusive, are formed of corrugated board and the marginal portions of the several plies are secured together by longitudinal stitching I5 and a bottom stitching I6. The upper end of the envelope I0 is initially open and an inner closure ap I'I extends from the upper 2 end of outer ply I2 and is formed with upwardly convergent end edges i8. The inner nap I'I is adapted, when in closed position, to be extended over the upper ends of plies l2, 4 and I3 and to be inserted between plies II and I3, as shown in Figure 3.
An outer sealingI iiap I9 is formed as an extension of ply or wall II and is adapted to be extended over the upper ends of all of the plies, as shown in Figure 3, and to overlap the outer ply iti. An adhesive tape 29 is adapted to be extended horizontally across the flap I9 and the ply or wall i2 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 2| which is formed of a pair of outer corrugated plies 22 and 23 which are integral with each other, as indicated by the bend or fold 24 along the longitudinal edges of these plies. An inner pair of plies 5 and 26 is disposed between the outer plies 22 and 23, and the innerplies 25 and 26 are also formed integral with each other along the longitudinal fold line 21 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 of stitching 28 and a lower line of stitching 29. The upper end of the envelope is provided with a tapered inner ap 3B similar to flap I'I and is also formed with an outer ap 3| similar to iiap i9.
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 bottorn integral bend or fold 34. An inner pair of corrugated plies 35 and 36 is disposed within the outer plies 32 and 33, and the inner plies 35 and 3S are connected together by an integral bend or fold 3l. A closure ap 3S 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 adhesive on the inner face of the flap 33 or by means of an adhesive tape similar to tape 2U.
The envelopes hereinbefore described provide a container for receiving various types of articles which have heretofore been packaged in standard types of containers or any other types of packagingmaterials 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 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 outer and inner plies will be protected against bending or other injury during the packing or shipment thereof.
I do not mean to comino myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claim.
What is claimed is:
An envelope type container comprising an outer pair of individual corrugated plies, each of said plies comprising an inner corrugated layer and an outer non-corrugated layer, an inner pair of individual corrugated plies, each of said plies comprising an outer corrugated layer and an inner non-corrugated layer, means securing all of said plies together about three edges thereof,
an outer non-corrugated closure ap carried by the free edge of the outer layer of one of said outer plies, and an inner non-corrugated closure flap carried by the outer layer of the other one of said outer plies, said inner flap being extendable over the free edges of said inner plies and engageable between said one outer ply and an adjacent inner ply, said outer ilap engageable over the free edges of all of said plies, and means securing said outer flap to the outer side of said other outer ply.
