- 3 Claims.

This invention relates to a package for manually dispensing powder, such as a garden insecticide.

It has heretofore been proposed to provide bellows containers for dispensing powder. However, most of these containers have been expensive to manufacture and have had the disadvantage of not discharging the powder uniformly and evenly. They have discharged an excessive amount of powder when new, and much powder has been wasted. I have devised an improved bellows container, which is inexpensive to manufacture and which discharges an even spray of powder on each compression of the bellows.

The container or package which I have devised consists of a paper envelope including bellows folds connected between front and back panels along either side -of the envelope. Perforated cardboards are placed against the inside faces of the front and back panels of the envelope. The container tapers from an expanded end to a narrow end where a notch is cut to permit discharge of the powder. At the narrow end of the container, the cardboards are arranged so that they prevent powder from passing directly to the notch between their ends. The powder is thus compelled to pass through the perforations in the cardboards and thence between the cardboards and the envelope in order to reach the notch. Each time the expanded end of the package is compressed a uniform spray of powder is discharged from the notch. Y

Other objects, features, and advantages of the present invention will become apparent or will be pointed out in connection with the following detailed description of an illustrative package in accordance with the invention, reference being made to the accompanying drawings wherein:

Fig. 11 is a front view of the package with the closure extended as in Fig. 6;

Fig. 12 is a view similar to Fig. 11, but with the closure in its nal position as in Fig. 8, and with the notch cut in the package;

Fig. 13 shows a modified form of'cardboard construction; and

Fig. 14 is a side elevation of the cardboard of Fig. 13 folded and ready for insertion in the envelope.

In Fig. 1 there is shown an envelope blank I5 which may be made out of any suitable heavy paper. The paper is preferably water repellent. The blank I5 is creased along the horizontal and vertical dot and dash lines and along the diagonal dot and dash lines, so that it can be readily folded to form the envelope. Dotted lines I6 are printed on the blank to show where the notch is to be cut. 'I'he blank includes a central portion I1 which forms the front panel of the envelope, portions 20 and 2| which form the bellows, and portions I8 which together form the rear panel of the envelope. The portions above the line e-f, including a ap I9, are folded toform a closure at the small end of the package. The portions below the line g-h form the other end of the package.

In making the package, the blank is first formed into a tube by bending it around a suitable mandrel so that the edges of the panels I8 and I9 abut or lie close together. A strip of paper 22, the same length as the blank I5, is pasted to the inside of the panels-I8. This strip 22, as best shown in Fig. 9, or erlaps the panels I8 sufficiently to form a tight closure. The panels 20 and 2I are then folded inwardly between the front and rear panels I1 and I 8 with the fold between panels 20 and 2| lying at a-b-c-d as shown in Fig. 10. A gusset is formed by the two triangular portions between the points b and c. It will be understood that instead of using a separate strip of paper 22, one of the panels I8 may be made wider than the other so as to form a lap joint.

The cardboard used in the package are shown in Figs. 2 and 3 at 23 and 24 respectively. Each of these cardboards is just a trifle smaller than panel Il and has a number of perforations or pin holes 26 formed in it. Cardboard 23 has a notch 25 cut in one end to coincide withfthe dotted lines I6. If desired the notch 25 may be made larger than the area I6. Cardboard 24 is creased along the line 21 and is slit as shown at 28 to form a flap 29 and hinged portions $0. Each of the portions 30 is approximately the same width as the distance between the inner corners of the bellows folds at the small end of the package. It will be understood that although cardboard has been mentioned as the material of which the members 23 and 24 are made, other stiff material may be used. The number and size of the pin holes may be varied, and, if desired, such pin holes may be omitted from one of the cardboards.

After the envelope has been formed into tubular shape, the cardboards are inserted in the envelope as shown in Fig. 5, the flap 29 being bent down. The portions of the blank between the lines g--h and i-y' are then pressed upwardly to form the end portions 36 and 31 of the package.' The portions of the blank below the line i-y' are then doubled over and stapled as shown at 38 in Figs.' 6 and 11. The portions 36 and 31 are then pressed inwardly to form a V as shown in Fig. 8. In this way, the two triangular portions of the gusset which lie between b and c in Fig, are doubled against each other.

In order to complete the package it is only necessary to ll it with powder, fold the ap I9 and the portions of the envelope above the line e-f as shown in Fig, 8, and staple the doubled over portions of the package at opposite corners, so that the staples 39 pass through the hinged portions 30. The powder is thus sealed within the package.

. In order to discharge the powder from the package it is only necessary to cut the notch in the envelope as shown in Fig. 12 and then grip the wide end of the package between the thumb and the ngers. Each time that the bellows are compressed powder is ejected through the perforations 26 in the cardboards and thence between the cardboards and the front and rear panels of the envelope to the notch where the powder is discharged from the package. By constructing the ap 29 as previously described the powder is prevented from passing directly to the notch between the ends of the cardboards. The ap 29 also helps to expand the bellows. By constructing the envelope and cardboards as previously described, the front and rear panels of the envelope bulge outwardly as shown in Fig. 8 so as to leave room for the powder to reach the discharge notch. Inasmuch as the rear panel of the envelope is of double thickness, and therefore stiffer than the front panel, it is preferable to insert the cardboard, including the flap 29, adjacent the rear panel. When the bellows are compressed, the front panel bulges up to the notch, while the rear panel bulges 'sumciently to permit powder to pass between it and the end 40 of the cardboard where ap 29 is hinged. It will be seen that in the construction described, only the cardboard 24 is hinged to the portions 3U. If desired, cardboard 23 may be made theA same as 24, and the flaps 29 on both members may be folded in to give additional spring action.

In Figs. 13 and 14 there is shown a modied form of the cardboards 23 and 24 in which both of them are scored on the dot and dash lines 21, and in which the two cardboards are made from a single sheet of material, including like portions 43 which are scored along the lines 44 and 45 and which are cut away as indicated at 46. Fig. 14 shows the manner in which these cardboards are folded for insertion in the envelope.

My package thus comprises an inner container and an outer envelope, the powder being retained in the inner container andbeing discharged upon the compression of the bellows throughvperforations in the inner container and thence between the inner container and the outer envelope to the discharge notch. y

The terms and expressions which have been employed are used as terms of description and not of limitation, and there is no intention, in the use of such terms and expressions, of excluding any equivalents of the features shown and described, or portions thereof, but it is recognized that various modications are possible within the scope of the invention claimed.

What I claim is:

l. A package of the character described comprising a tapering envelope having front and rear panels connected at either side by bellows folds, a pair of perforated cardboards lying within the envelope and adjacent the front and rear panels. a discharge opening in the narrow end of the envelope, means to prevent powder from passing directly to the discharge opening between the ends of the cardboards, and means to close the ends of the envelope.

2. A package as claimed in claim 1, wherein the cardboards are just a trle smaller than the front and rear panels of the envelope, and

wherein the means to prevent powder from passing directly to the discharge opening comprises a flap on one of said cardboards bent over against the other cardboard at the small end of the envelope.

3. A package as claimed in claim 1, wherein said cardboards are joined by hinged sections.
