Claims. Cl. 222-566) This invention relates to containers suitable for powders and is herein illustrated in some detail as embodied in a paper and cardboard container suitable for holding and delivering tooth powder.

Containers for tooth powder and many analogous powders have presented many problems. Often they have been made of glass or metal with an attached metal delivery head or spout, but these involved expensive materials which were either fragile or diflicult to produce except by special machinery, were expensive to ship empty both because of space occupied and because they had to be packed in cartons or boxes strong enough to protect them, had to be handled repeatedly, occupied expensive storage space, and were either diiiicult to fill or could only be filled by the aid of expensive machinery.

Containers made of other materials were open to many of the same objections, and in time of war, were limited by the same kind of priority orders.

Packages of paper or cardboard or of combinations of these materials were limp or were likely to leak or were difficult to handle without danger of damaging them. Leakage often took the form of dusting because a trivial leak would often slowly sift through it small amounts of dust which annoyed housekeepers and storekeepers and seriously militated against the salability of the package because the adhering dust made the package look like a careless and wasteful job.

According to the present invention, the foregoing and other objections and disadvantages are overcome and a container is provided suitable l" for holding tooth powder in a form satisfactory to the retail trade, cheap to produce, sturdy enough to meet the exigencies of handling in that trade, easily manufactured either by hand or by automatic machinery, and Well adapted to be filled by automatic machinery of a standard type.

In the form disclosed, an integral box or unit is built up of two trays, like open top boxes, one tting into the other. A separately mounted top or dispensing sifter is adapted to be laid on an opening provided at one end of the trays, usually being glued to the tray ends to make a dust-proof joint and units. An outside wrapping or cover box is adapted to be slipped down over the top mounting to enclose the nested trays and to be held in place by flaps folded down to enclose the unit, thus cooperating with the adhesive to hold the top in place so that it closes the tray openings and serves for dispensing powder.

Other and iurther objects or the invention will be obvious upon an understanding of the illustrative embodiment about to be described or will be indicated in the appended claims and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice.

A preferred embodiment 4of the invention has been chosen for purposes of illustration and description and is shown inthe accompanying drawings, forming a part of the specification, wherein Fig. 1 is an exploded perspective showing diagrammatically the construction of the parts and their relationship to each other;

Fig. 2 is a perspective view of the iinished package; and

liig. 3 is a section along the line 3-3 of Fig. 2 to show the relationship of parts thereof.

In the form shown, an inner dust-proof unit is built up from open top tray-like boxes I0 and I I. In the form shown, the box I0 is made of a single piece of cardboard which was scored along the lines I2 and I3 to provide the sides I4 and I5 made by turning up the edges of the cardboard along the scored lines I2 and I3 and also scored along end lines I6 and I1 to provide ends I8 and I9 made by turning up the edges of the cardboard after the corners (not shown) had been cut out so that the ends and sides meet along the vertical corner lines 20.

The bent up ends and sides along the lines 20 were sealed together by thin strips of paper 2I which proved adequate when covering the length of the corner and extending over a small area of the sides and end, and did not need to overlap the bottom to close the solid angles 22, if the scoring was accurately done, although the strips may extend on to the bottom 23 of the tray and thus seal the solid angles 22.

Before the tray was made, an opening 24 was cut for delivering the contents to a sifter or dispensing outlet 25 in the iinished container.

The tray-like box I I to t fairly closely within the tray Ill is shown as similarly constructed from a sheet of cardboard which was scored along sides at 26, 21 and along ends at 28, 29 to provide sides 3I and

ends

32, 33 which are closed at the corners 34 by strips 35 to hold the tray together and make dust-proof corners. The sides 3| and

ends

32, 33 are shown as bent down from a bottom (shown at the top) 36, and as having an opening 31 in the end 33 adapted to register with the opening 24 of thetray IIJ when the tray II rests inside of the tray I0.

The tray-like box II is preferably adapted to slip easily but not loosely into the tray I0, and

may be retained within the 1atter by a cover sheet 38. The cover sheet 38 is shown with edge flaps 39, cut out adjacent the corners 48, adapted to be bent downwardly so that these edge flaps slightly overlap the sides and ends of the nested tray-like boxes ID and Il these overlapping portions 39 may then be glued to the sides I4, l5 and ends I8, i9 of the outermost tray-like box Ill to securely hold the nested tray-like boxes I and. Il together so as to form what may be termed a receptacle unit. The cover sheet 38 may thus hold the lower or free tray edges 42 of the sides 3| and of the

ends

32, 33 abutting against the inner bottom 23 of the tray Ill; the cover sheet 38 thus minimizes the possibility of a powdered material accidentally leaking out of the resulting receptacle unit.

While it is feasible to utilize the nested traylike boxes I0 and Il as a unit it is preferable to retain them in assembled relationship with the cover sheet 38, as the latter type of unit provides a more sturdy construction.

Ordinarily, the unit formed by the united trays l0 and Il is lled at this time with the tooth powder or other material through the now aligned openings 24 .and 31.

Thereafter, the opening 24, 31 is closed by gluing to the end 33 a cardboard sheet 43 forming a mount carrying a suitable nozzle or dispensing top 44, usually made of metal. The top 44 is usually provided with an outer screw thread 45 adapted, when the container is complete, to be closed by an internally threaded cap 46 which may be either plastic or metal.

The receptacle unit formed by the nested traylike boxes I 0 and Il and the cover sheet 38 is adapted to be inserted into an outermost cover 41, which preferably ts around thereceptacle unit and may take many forms varying from an ornamental paper Wrapping to a reinforcing cardboard boX. After the receptacle unit and the cover 41 are in assembled relationship (Figs. 2 and 3) a closure cap 46 may be applied to the screw thread 45.

In the form shown, the cover 41 is illustrated as a cardboard box having sides 48 formed from a sheet which is suitably folded (and scored if need be) at the four corners 49, and overlapping a little at 50 where the edges are glued together to form the tubular part.

In the form shown, the metal sifting top 44 projects through an opening l in the end 52 made by folding over an edge flap 53 having the opening 5| so as to overlie folded over side flaps 54 which also, at least partly enclose the opening 5I, and then tucking in, by turning on a scored line 55, an extension 56 of the flap 53 so as to lie inside the side of the cover 41. After the flaps are tucked in and glued, if desired, the unit l0, I l or a unit l0, Il, 38 may be slipped into the cover 41 and the

flaps

51 and 58 turned down, in the form shown, and then the ap 59 turned down, and either glued or else its flap B0 is tucked in to lie against the inner wall of the cover.

The cap 46 is then screwed on, and the container is ready for shipment. As pointed out hereinabove, the containers will ordinarily be filled with material prior to completion of manufacture thereof, but it is feasible to ship them empty for subsequent lling. The outlet member is conveniently formed with a threaded portion 45 and a base 6l, and inserted with the end 25 rst through the sheet 43 and then the threaded end is shaped on a suitable anvil (not shown) to form an vannular web 62 above the sheet 43, thus 4 firmly holding the end 25 in place and providing a dust-proof joint in a smooth sheet 43.

It will be noted that the steps of manufacture and fitting are simple and well adapted to be carried out either by hand or by automatic machinery.

As various changes may be made lin the form, construction and arrangement of the parts herein without departing from the spirit and scope of the invention and without sacrificing any of its advantages, it is to be understood that all matter herein is to be interpreted as illustrative and not in a limiting sense.
