ENVELOP.

Specification of Letters Patent.

Patented July 26, 1921.

Application filed .Tune 21, 1920. Serial N o. 390,389.

To all whom t may concern:

Be it known that I, EDWARD J. REILLY, a citizen of the United States, residing in the city of Baltimore and State of Maryland, have invented certain new and useful Improvements in Envelops, of which the following is a specification.

This invention relates to envelops, and has for one of its objects to produce an envelop having means whereby the contents are held spaced from one edge to protect the contents from injury when the envelop is opened.

Another object is to provide an envelop having means for protecting the contents from injury when the envelop is opened and likewise to provide a convenient tearing line, toy facilitate the opening.

Another object is to provide an envelop having means for protecting the contents from injury when the envelop is opened, locking the side walls of the envelop together, and likewise to provide a convenient tearing line, to facilitate the opening.

With these and other objects in view, the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claim, and in the drawings illustrative of the preferred embodiment of the invention.

Figure 1 is a view of a conventional envelop with the improvement embodied therein, 4

Fig. 2v is a section on the line 2-2 of Fig. 1,

Fig. 3 is a perspective .view partly in section of portions of the side walls of an envelop illustrating the construction and arrangement of the combined contents protecting and locking elements,

Fig. 4 isa sectional detail in perspective.

Fig. 5 is a perspective detail illustrating the construction of the blank from which the envelop is formed.

The improvement may be embodied in any of the various forms of envelops, and it is not desired to limit the invention in any manner in this respect, but for the purpose of illustration, is shown embodied in a conventional form of envelop; in which 10 represents the face or address side or wall and 11 the closure Hap slde, or wall.

one wall are insertible through the slits of l the other wall, preferably alternatelyl as illustrated in F igs. 3 and 4:. i

By this means three very important results are accomplished.

F irst,-efl"ectual tearing perforations are l produced to facilitate the opening of the envelop.

Second,-the opposite walls are locked together to prevent their premature separation until the contents are to-be removed, and,

Third,-a stop element is formed across the envelop to prevent the contents of the envelop from working to the extreme end in position where they are liable to be multilated if the end of the envelop is torn o' in opening.

It is acommon practice to open envelops .by tearing-off one end and this operation is liable to fracture or mutilate the contents if thr latter are disposed close to the torn oil" en With the improved envelop the contents are prevented from passing beyond the .interlocking tongues and slits, and consequently will not be injured or fractured when the envelop is opened, as will be obvious. The coacting interlocking tongues and clefts or slits will be produced by a suitable implement or machine, not shown, when the envelop is manufactured or subsequent thereto, and the envelops will be furnished to the trade with the improvement embodied therein.

The preferred embodiment of the invention is disclosed in the drawings and set forth in the specification, but it will be understood that any modifications within the scope of the claims may be made -in the construction without departing from the principle of the invention or sacrificing any of its advantages.

IVha-t I claim is: An envelop having alternating tongues 5 and slits in its opposite Walls adjacent one of-its folds, and extending from near one edge to near the other, the tongues of one well being disposed opposite the slits of the other Wall and extending through the slits of the same.

In testimony whereof I affix my signature hereto.

EDWARD J. REILLY.
