FRANCIS M. ORISWELL, OF \VASHINGTON, DISTRICT OF COLUMBIA.

ENVELO P.

SPECIFICATION forming part of Letters Patent No. 581,019, dated April 20, 1897.

Application filed June 27,1896. Serial No. 597,135. (No model.)

a citizen of the United States, residing at Washington, in the District of ()olumbia,have lnvented certain new and useful Improvements in Envelope; and I do hereby declare the following to be a full, clear, and exact de scription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to envelops, but more particularly to those designed to hold and retain effervescing powders.

In the preparation of sedlitz-powders and the like for the market it has been the practice to wrap each powder separately and then place the two effervescing powders into an envelop, third wrapper, or other closure, so as to prevent their being misplaced or of employing either one without the other. Such a process, however, consumes considerable time, thereby adding materially to the cost of the article, and at the same time requires the removal of the different coverings before the person wishing to use the powder can get at them.

The primary object of my invention is to overcome these objectionable features by providing an envelop having independent compartments into which the different powders maybe placed, whereby the time and expense incident to the preparation of sedlitz-powders and the like for the market, as well as the space occupied by the package, may be materially reduced.

Afurther object of the invention is to provide a simple, efficient, and inexpensive envelop which may be employed in various connections.

The invention will first be more particularly hereinafter described, and then pointed out in the claims at the end of the description.

Reference being had to the accompanying drawings, forming a part of this specification, Figure 1 is an elevation of a preferred form of envelop. Fig. 2 is an edge view, representing the flaps partly open. Fig. 3 is a diagrammatic vertical sectional View, on an enlarged scale, of a portion of the envelop, illustrating one way of forming the seal or partition, so as to separate the powders. Fig. 4 is an elevation of the blank from which the envelop is formed. Fig. 5 is an elevation of an envelop similar to that shown in Fig. 1, except that the partition is held together differently. Fig. 6 represents an elevation of a blank of another form of envelop. Fig. 7 is an enlarged end view of the form shown in Fig. 6 when folded. Fig. 8 is a perspective view of the blank in process of being folded. Fig.9 is an enlarged vertical sectional view of the partition, and Fig. 10 is an enlarged vertical sectional view of a slightly-modified form of seal.

In the drawings, A may designate a blank, preferably formed from a single piece of paper or other suitable material, having the side flaps a and a, adapted to be folded over upon the body portion a at a point indicated by the dotted lines a The flap a is preferably wider than the flap (1, so as to permit the latter to rest upon and be sealed to the former in the usual or in any preferred manner, so as to place the outer edge of the flap a centrally of the body portion a in order to present a neat appearance and to provide an open-ended body or receiving portion for the insertion of the material or powders. At a and d are end flaps provided with pasting or sealing edges adapted to be folded over upon and be sealed to the side flaps, so as to close the open ends of the envelop and to retain the contents therein, the whole being of the form shown or of any preferred form of envelop.

For the purpose of dividing the body portion into compartments, so as to separate the effervescing powders, I preferably form a partition a between the open ends transversely of the envelop. This isaccomplished, preferably, byfolding the body or receiving portion of the envelop upon itself in the manner indicated in Fig. 3 and then forcing the parts together, as shown in Fig. 2, the abutting surfaces being provided with paste or other sealing means for rigidly holding them together, or the parts may be held by stitching, as at (1 Fig. 5, or in any other suitable manner. By this means the powders may be placed in separate compartments and sealed by means of the flaps a and 6&5, so as to effectually prevent the mixing or commingling of the effervescing powders.

Instead of providing the envelop with'two open ends, as in Fig. 1,1 may provide ablank of the usual form having the partitions arranged so that the compartments may be simultaneously closed by a single flap in order to permit the effervescing powders to be placed in the envelop without changing its position and without permitting the powders to commingle.

In Figs. U to 9, inclusive, the blank 0 is substantially or may be the same as in Fig. t. In this case the folding and forming of the partition for separating the envelop into compartments is effected while the envelop is being formed in order to distribute the folding on both sides of the body or receiving portion. The blank maybe first folded upon itself with the dotted lines 0, with the edges of the side flaps as guides, in a manner similar to folding the entire envelop, as shown in Fig. 3, and then the flap 0 folded over so that the sealing edge 0 may be united to the body portion, Fig. 8, and then the flap c folded over upon the body portion and flap 0, so as to form a vertical and transverse joint through the sealing edges 0'. The flap 0 may now be folded upon the flap 0 and body portion, so as to be united thereto by the sealing edge e, and then the flap 0 may be folded over upon the flaps and c so as to form a transverse and longitudinal joint therewith through the sealing edges 0 thus providing a neat and effective partition between the ends of the body or receiving portion, so as to provide separate compartments for the powders adapted to be closed by the end flaps c, in a manner similar to the form shown in Fig. 1. It will be seen that after the blank is folded transversely both of the flaps c and 0 may be folded over thereon and then both flaps c and c folded over upon these flaps and the body portion, or, if the blank is in the form shown in Fig. 4-, the blank is first folded transversely and then one of the side flaps is folded over and then the other, when it desired to form the partition as the envelop is formed.

Fig. 10 represents a form in which each side is folded upon itself so as to distribute the fold and to provide a partition so as to separate the envelop into compartments, in which case the blank may be sealed along one of its edges instead of centrally of the body portion. I thus provide simple, effective and inexpensive means for separating the powders, without necessitating their being placed or wrapped in separate packages and then placed in an envelop, so as to prevent being mislaid or for other causes, and which will permit their removal when desired.

here the envelop is employed for sedlitz-powders, the body portion maybe colored to indicate the different powders, and the partition may be placed so as to provide different-sized compartments of a capacity suf ficient to retain and hold the powders according to their relative proportions.

Within each compartment may be placed a paraffin or other lining to prevent the air or moisture affecting the material therein, and other changes may be made without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. An envelop having its body portion bent or folded upon itself and the opposed folded parts secured together so as to provide a partition dividing the envelop into separate compartments, substantially as described.

2. An envelop having its receiving portion provided with a partition forming independent open-ended compartments and means for closing the open ends of the compartments, said partition being formed by bending the body or receiving portion upon itself and se curing the opposed surfaces together, whereby the effervescing powders may be placed into and retained within the envelop without mixing, substantially as described.

3. An envelop having its receiving portion provided with a partition extending transversely thereof so as to form independent open-ended compartments of different sizes, and a flap for closing each compartment, said partition being formed by bending the body or receiving portion upon itself and securing the opposed surfaces together, whereby effervescing powders may be placed into and retained within the envelop without mixing, substantially as described.

it. An envelop formed from a single blank having side flaps folded over upon and secured to each otherso as to form a receiving portion with opposed open ends and provided with a partition extending transversely of the receiving portion so as to divide the envelop into independent compartments, and flaps for closing the open ends of the compartments, said partition being formed by bending the body or receiving portion upon itself and securing the opposed surfaces together, whereby effervescing powders may be placed into and retained within the envelop without mixing, or requiring a separate wrapper therefor, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
