ENVELOP FOR CONTAINING AND DISPENSING POWDER.

Application filed December 29, 1913.

To all whom it may concern Be it known that I, BENJAMIN P. RIGH- ARDSON, a citizen of the United States, residing at Brookline, in the county of Norfolk and State of Massachusetts, have in vented certain new and useful Improvements in Envelops for Containing and Dispensing Powder, of which the following is a specification.

This invention appertains to improvements in envelops or containers for the reception and dispensation of powder or pulverized material, and is designedto provide an envelop, container or receptacle which is made from a single piece of paper or fabric, and is of such construction that when powder is placed therein the same may be dispensed or sifted therefrom by the application of pressure to the opposite edges of the envelop adjacent to its end, the construction' also being such that the package or envelop will be normally closed without using parts which are foreign to the make-up of the same.

A further object of my invention is to provide a receptacle or envelop that has a perforated end portion that is divided by a fold or crease which is parallel with oppositely folded or creased parts, said folds or creases being of less length than the dividing fold or crease, and with end or corner folds, providing a construction by which when pressure is simultaneously applied, to

the opposite edges of the envelop adjacent to the folds or creases, the position of the end of the envelop will be changed from one which serves to normally close the envelop against discharge of its contents to a position whereby the powder contained in the envelop may be dispensed therefrom and when pressure is removed the parts will resume their normal position.

In the accompanying drawings which illustrate a preferred form of the invention, Figure 1 is a perspective view which shows the envelop in its normal position. Fig. 2 is a perspective view of the envelopshow ng one end in position to admit of the sifting or dispensing of its contents through its perforated end. Fig. 3 is a sectional view taken on the dotted line 3 3 of Fig. 2. Fig. 4 is a side elevation of one end of the envelop as it appears prior to being folded or creased, the folds or creases being indicated by dotted lines, and Fig. 5 is a view which illustrates the manner of sifting or dispens- Specification of Letters Patent.

ing the contents of the envelop by simultam neously exerting pressure upon its opposite edges.

The envelop or container 1, may be made up in any suitable form except as to the end 2, which end is folded or creased in a manner to provide diamond folds 3 at the opposite corners of the end2, which end is also .provided with cross folds .or creases 4 of less length than the width of the envelop and a centrally located fold or crease 5 which extends the entire width of the envelop, this fold or crease 5 mav be the one formed at the opposite end of the envelop from its mouth which is closed by a flap in the usual manner after the envelop has been filled. The corner or diamond folds 3 have on their inner sides bends or folds 6 which extend from one side to the other side thereof and there are present bends or folds which are continuations of the side or edge folds 7 of the envelop.

The manner of folding the envelop will provide a satchel-bottom or end in which the centrally located fold, crease or bend 5 will normally extend inward to locate the adjacent portions which are perforated below the folds orcreases 4, the ends of the rectangular perforated portions between the folds or creases a being overlaid by the corner portions 3.

The direction in which the paper from which the envelop is made is folded or creased is fully shown by Figs. 2 and 3 of the drawings, and the resiliency of the paper or fabric from which the envelop or receptacle is made and the manner and direction bf the folds tend to maintain the surface of the parts bounded by'the folds 4 and 6 and the corner folds in contact so that the perforations 8 will be practically sealed against the discharge of the contents of the envelop, and when in such position the corners of the envelop will be folded inward as shown by Fig. l of'the drawings.

The perforations 8 are preferably located so that when the end 2 of the envelop 1 is positioned as shown by Fig. 1 the perforations will be out of alinement to be overlaid by a non-perforated portion of the envelop for the purpose of tpreventing the sifting of the contents 0 the envelop through the perforations, when the parts are in their normal position.

To dispense toilet-powder or the contents of the envelop, pressure is simultaneously applied to the edges adjacent to the end, as shown by Fig. 5 of the drawings, and the pressure so applied will cause the corner folds to be moved away from bottom and the center fold 5 to be moved outward to bring the perforated portions toward the same plane, so that the contents of the envelop may be sifted therefrom.

This envelop or receptacle may be used for talcum or other toilet-powder and for other pulverized material and provides a cheap and efficient container and dispensing package. The satchel-bottom end of the envelop and its perforations may be modified as to their construction, particularly as to the corner or diamond folds, as the ends in view may be attained by 'a modified form of the diamond or corner folds, the leading feature of my invention being to provide in a unitary structure a container having a perforated portion which is divided by a longitudinal crease or fold which with other creases or folds normally maintains the parts in a position to prevent thesifting out of the contents of the container and in which the position of the parts will be changed by applied pressure to permit the contents to be. sifted out through the perforations.

I claim 1. An envelop or paper receptacle for dis pensing therefrom powder contained therein comprising an end that is folded to pro-. vide a self closing dispensing end, a portion thereof having perforations therethrough which portions will normally overlie each other and having a centrally located fold or bend, end folds or bends which are parallel with the central fold or bend, diamond shaped corner folds a portion of the diamond shaped corner folds lying Within the end fold of the envelop, substantially as set forth.

2. A paper envelop or container made up to 1')rov.ide one of the end portions thereof with an integral centrally and longitudinally folded part havingperforations therethrough, folds parallel with the central longitudinal fold to admit of the perforated part lying between thesides of the envelop, corner folds at oppositeends of the envelop the parts constituting the corner folds being positioned between the other folds, such structure being orgiinized so that the position of the parts will be changed by the application of pressure to the edges of the envelop adjacent to such folded portions.

3. An envelop or paper container for dispensing powder comprising end folds and an intermediate fold between and in an opposite direction from the end folds and extending from edge to edge of the envelop,

perforations through that portion of the envelop which is infolded, diamond shaped folds at the corners of the envelop said folds being intersected by the intermediate fold and by transverse folds to normally lie within the ends of the infolded portion of the envelop, substantially as set forth so that the infolded portions of the envelop will be moved by pressure applied to its edges adjacent to the folds to spread apart the infolded and perforated portion of the envelop so that the contents may be sifted from the envelop through the perforations.
