2 Claims.

The invention relates generally to dispensing containers and primarily seeks to provide a novel container structure adapted for packaging and dispensing powdery substances, such as scouring powder or the like, and a novel holder therefor.

Cans in which scouring powder is packaged usually are formed with cardboard bodies and metallic end closures, one of said closures having dispensing apertures therein through which the powder can be dispensed. If such cans areallowed to become wet, as by frequent contacting thereof with wet hands, the bodies become soft and powder leaks will develop at the junctures of the metal end closures with the bodies or in the body walls themselves. In order to avoid this objectionable feature it has been proposed to provide can encasing holders in which to insert the dispensing cans and which protect them from wetting contact and provide a dispensing unit which is neat in appearance. Such holders of which I am presently aware have not been entirely satisfactory because of being impractical and unnecessarily complicated in structure. In some it has been necessary to provide registering aperture sets in the holder and in the can top, and in some clearances are provided which permit accumulation of powder and moisture between the ends and wall portions of the can and holder units. It is the purpose of the present invention to provide an improved powder dispensing can and holder combination which is attractive in appearance and subject to being manufactured at low cost, and which is designed to avoid the objectionable features embodied in the known structures referred to hereinabove.

An object of the invention is to provide a powder dispensing can holder of the character stated having an opening in one end through which to receive the dispensing can and which is closable with a removably mounted end closure, and an overhanging flange at its other end defining an opening through which the powder can be dispensed through the dispensing apertures in the can top, said flan e havin an annular shoulder portion engageable in sealing contact with the can top inwardly of the periphery thereof for preventing passage of powder between said shoulder and the can top and into the space between the can and the holder.

Another object of the invention is to provide a structure of the character stated in which the can has a raised portion in its top disposed to project upwardly through the opening. in. the holder end flange and in which the powder dispensing apertures are formed.

Another object of the invention is to provide a structure of the character stated in which the raised portion on the can top has a tapered annular wall with which the overhanging holder end flange engages in sealing contact.

Another object of the invention is to provide a structure of the character stated in which the can is removably held in place in the holder and with its top in sealing contact with the annular shoulder of the holder end flange by a threadably mounted end closure.

Another object of the invention is to provide a structure of the character stated in which the holder is formed of. plastic.

With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims, and the several views illustrated in the accompanying drawing.

In the drawings:

Figure 1 is a top plan view of a powder dispensing can forming a part of the invention.

Figure 2 is a side elevation of the can shown in Figure 1 V Figure 3 is an inverted plan view of the can shown in Figure 1.

Figure 4 is a plan view of a holder structure for receiving the can illustrated in Figures 1 to 3.

Figure 5 is a side elevation and part vertical section illustrating the holder shown in Figure Figure 6 is an inverted plan view of the holder with the bottom closure in place.

Figure 7 is an inverted plan View of the bottom closure per se.

Figure 8 is a side view of the bottom closure shown in Figures 6 and 7.

Figure 9 is a vertical cross section taken onthe line 53-9 on Figure '7.

Figure 10 is an enlarged fragmentary sectional view, parts broken away, showing the can mounted in the holder structure.

Figure 11 is an enlarged part side elevation and part vertical section illustrating a slightly modifled form of the invention.

In the example of embodiment of the invention herein disclosed, there are included a powder dispensing can generally designated 5 having a cardboard body 6, and a bottom end closure 1 and a top end closure closure 8.

The top closure 8 is formed to include a raised, centrally disposed circular portion or knob extension 3 which is preferably surrounded by a tapered or frusto-conical wall portion H] which is in turn surrounded by the main body portion ll of the closure which also may be frusto-coniform in shape. Like the bottom closure 7, the top end closure 8 may be secured to the body 6 in any approved manner, as by a rolled seam [2. In the simple illustration herein disclosed, the tapered, circular knob or protuberance defining wall l l is disposed at an angle of 45, but it is to be understood that this particular angle of projection of said wall may be modified without departing from the purpose of the invention.

It will be apparent by reference to Figure l of the drawings that the raised knob or protuberance on the top closure of the can is provided with the usual punch-out apertures l3 through which powder may be dispensed from the can.

The holder structure in which the can illustrated in Figures 1, 2 and 3 is removably mountable is illustrated in Figures 4, 5 and 6. This holder preferably is constructed of a molded plastic and includes a generally cylindriform body l -l which may be slightly tapered toward the top in the manner clearly illustrated in Figure 5. The body It is open at one end as illustrated in Figures 5 and 6 so as to facilitate introduction of the powder dispensing can thereinto, and the open end of the body is chamfered as at 5 and provided with an internal thread it. At its other or upper end the holder is provided with an inwardly turned flange ll disposed to overhang the top end of the powder dispensing can when it is mounted in the holder in the manner clearly illustrated in Figure 10. The flange ll defines a central opening I8 disposed to receive the raised portion or knob 9 extending from the powder dispensing can, and said opening preferably is flared, as at W, at the same angle as the tapered can projection wall portion 49 in order to provide a sealing seat presented for sealing contact with said tapered wall portion. It will be obvious that the inwardly directed flange il has a certain amount of resiliency inherent there- The closure for the bottom of the powder dispensing can and casing holder is illustrated in detail in Figures '7, 8 and 9 and preferably is formed of molded plastic. This closure comprises a disk generally designated 28 having a convex center body 2i shaped to provide a can end abuttin annulus 22 which is surrounded by an outwardly directed flange 23. The flange 23 is shaped to form a single helical thread 2 3, and to include finger pieces 25 which will facilitate threading of the closure into the internal thread H5 or the holder i i in effecting a closure of the holder as illustrated in Figure 6. It will be apparent by reference to Figure 9 that the closure member is in the nature of a thin shell having inherent resiliency, and when the closure is threaded into the lower end of the holder is it will engage the bottom end of the powder dispensing can in the manner illustrated in Figure 10 and will secure the can in the holder and maintain a resilient contact between the flange H and the top of the can inwardly of the periphery of the can top, or more specifically will maintain a resilient contact between the internally flared sealing wall 59 of the flange and the externally tapered sealing or seating wall ll! surrounding the central protuberance or knob 9 of the can top. It will be apparent by reference to Figure 10 that the parts are so proportioned that the peripheral portion Of the can top, or in other words the seam E2, is held out of contact with the holder flange H and thus cannot interfere with the sealing contact between the holder flange and the can top protuberance or knob.

With the can mounted in the holder in the manner clearly illustrated in Figure 10, the powdery substance may be dispensed from the can through the punched apertures l3 without any interference by the holder flange IT, and the sealing contact of the flange with the can top protuberance or knob assures against leakage of the powder between the can top and the flange, and also into the space surrounding the can within the holder.

In Figure 11 of the drawings, there is illustrated a slightly modified form of the invention in which the powder dispensing can is provided with a cylindriform raised portion or protuberance 21. In this form of the invention the raised portion 21 of the can top has a rather snug fit in the opening 28 in the holder flange 29, said flange having an inherent resiliency as in the previously described form of the invention, and being equipped with a flared sealing wall portion 36. The sealing wall portion 38 of the holder flange is disposed to engage in sealing contact with the frusto-coniform main body portion 3| of the can top which surrounds the apertured central protuberance or knob 27. As in the previously described form of the invention the contact of the sealing surfaces 30 and 3| of the flange and can top respectively serves to prevent infiltration of powder into the holder in the space between the can and the internal wall portions within said holder, and the seam 32 by which the can top is secured to the can body 33 is held away from the adjacent end extremity or flange of the holder as at 34 so that it cannot interfere with the efficient sealing contact between said surfaces 36 and 3 I.

While preferred forms of the invention have i been shown for purposes of illustration, it is to be clearly understood that various changes in the details of construction and arrangement of parts may be made without departing from the spirit and scope of the invention as defined in the appended claims.
