This invention relates to cans such as are suitable for packaging, shipping and selling paint or other material of a nature that when it is allowed to stand, settling of some constituents occurs, this invention having for its purpose to provide a mixing device in the can by which mixing of the constituents before use may be readily efiected.
One of the objects of this invention is to provide a mixer of eflicient construction.
10 Another object is to provide a structure including the mixer which will add little to the cost of the can, so that it may be freely used for its intended purpose without the additional cost due to the presence of the mixer becoming an im- 15 portant item in the entire cost of the package.
For a more complete understanding of this invention, reference may be had to the accompanying drawings in which Figure 1 is a central vertical section through a can embodying the invention and before the annular top rim for receiving the can cover has been assembled therewith.
Figure 2 is a fragmentary section through the top edge of the can showing the top rim assembled and the cover in position to be applied.
Figure 3 is a detail section similar to a portion of Figure 1, but showing the handle for the mixer in operative position.
Figure 4 is a section on line 44 of Figure 1.
- Figure 5 is a perspective view of the can cover.
Figure 6 is a perspective view of the mixer and a bearing brace therefor.
Figure 7 is a fragmentary perspective View showing the cooperative securing portions of the 35, can and the bearing brace.
Figure 8 is a development of the mixer blade member shown in Figures 1, 3, 4, and 6.
Figure 9 is a development of a modified construction of mixer blade.
Figure 10 is a perspective view showing the blade made up from the blank of Figure 9 and showing one method of securing the mixer shaft thereto.
Figure 11 is a perspective view somewhat simi- 12am to Figure 10, but showing a further modification.
Referring first to Figure l, at is indicated a pail or can which may be formed of sheet material and provided with a bottom wall 2 and a side 50 wall 3 which may be joined as by crimping, as at 4. The top edge of the wall 3 is formed with an outwardly extending flange 5. Oppositely disposed on its outer face are a pair of bail-receiving ears 6. These may be of the well known con- 55 struction, comprising dished elements having their inwardly flanged margins l secured to the outer face of the wall member 3, as by soldering,
or in any other suitable manner, and having perforations 8 in their ends to receive the ends of a bail B. These bail ears not only serve to re- 5 ceive the bail 9, but they also serve to house and conceal sockets It (see Figures 1 and 7) which are formed by pressing the wall material I outwardly and within the areas covered by the bail ears. These depressions I form sockets for re- 10 ceiving opposite ends of a transverse brace member 5| which extends across the can below its flanged top 5. As shown this brace is a sheet metal stamping having marginal side flanges I2, end flanges l3, and corrugations I4. The cor- 15 rugations l3 and the flanges |2 form longitudinal stifiening ribs, so that relatively light and inexpensive sheet metal may be employed for this member. Between the corrugations l4 it is shown as provided with a bearing opening l5 within which may be journaled a shank l6 of a mixing device. This shank may be journaled at its lower end I! in a depression IS in the can bottom 2 and this can bottom may be provided with concentric reinforcing circular corrugations I9.
The member It carries at its lower end and in close proximity to the bottom 2 of the can, a mixing device shown best in Figure 6. This comprises a sheet metal member having an intermediate portion 22 which may be attached by any suitable means to the shank I6 and which, as shown, is tapered in width, its narrower end being uppermost. From this intermediate portion extend the oppositely disposed wings 2|, and a reinforcing bottom plate 22 may bridge the lower ends of both the wings 2| and the intermediate portion 20. The wing portions 2| may be curved, as shown best in Figure 3, so that as the mixer is turned it has a tendency to cut away any material which may have settled in the can and force it upwardly as shown by the arrows in this figure, thus to lift the settled material and stir it into the other contents of the can, while the lighter, unsettled material may flow in beneath the lifted 5 portion so that a thorough mixing action is produced when the shank H5 is turned.
The base member 22, the wings 2| and the in termediate portion 2!] may be formed up in various ways from a single sheet of material. As shown in Figures 3, 4, 6 and 8 the wings 2| are bent upwardly and backwardly from opposite edge portions of the member 22 and the portion 28 is formed by overlapping edges extending from the wings 2|.
As shown in Figures 9, 10, and 11, the wings Zla extend from opposite edges of a one piece intermediate portion 200., the base being formed in three portions 22a, 22b and 220. The blank is folded up with the portion 22b overlapping the portion 22a and an edge extension 22d from the portion 220 underlapping both, the notch at i and the openings y and 2 being brought into 35 turned and crimped as shown in Figure 2 to registry. These lapping parts are secured together by any suitable means such as spot welding or the like. The shaft or shank iiia, as shown in Figure 10, may be split at its lower end to take over opposite sides of the section 200. and then be extended through the openings .73, y and 2, after which the parts are closed together to firmly grip the sheet metal piece, or instead of splitting the shank the member 22a may be formed with a laterally ofiset channel 201), as shown in Figure 11, in which the shank may be suitably secured as by riveting or spot welding or by any other suitable method.
The bottom member 22 and the adjacent lower edges of the wings 2| may be corrugated to substantially fit the corrugations H] of the bottom wall ofthe can.
The mixer and the brace II are assembled in the can, it being an easy matter to spring out- 'Wardly the side wall I' along the diameter of the brace ll until the brace may be sprung into position in the sockets Ill. Thereafter a top rim member 25 shaped to receive the friction cover 27 shown in Figure 2 may be placed in position at the top of the can, and its outwardly extending top flange 28 and the flange 5 may be secure: the top member 25 in position. This member so stiifens the top portion of the can as' to prevent accidental distortion of the side Wall so that the parts are held firmly in position. The shank l6 below the brace II is preferably provided with laterally'extending portions 38, which may be struck out therefrom, in position to prevent the mixer from being pulled upwardly out of journaled engagement with the can bottomafter the brace H hasbeen assembled in the can. a Y
The cover 21, as shown in Figure 5, is preferably provided with a depression 35' for the reception of a handle or crank 36 which may be employed to rotate the mixer after the can has been opened. A flap 38 may be secured to the top face of the can coverand normally be extended over the depression 35, as shown in dotted lines in Figure 5, to hold the crank member 36 in place until it is desired to use it, whereupon the free end of the strip 38 may bepried up and the crank released. As shown in Figure 3, this crank comprises a shank 4% that the handle may be placed in position over the top end of the member Iii with its end resting against the shank portion'dil, thus to limit the extent to which the crank handle may be pressed down onto the member i6. By grasping 'the handle portion. 45 of this crank, the mixer l sufificiently to disengage the brace H,
may be turned to effect the desired mixing operation.
It will thus be seen that when the can has been filled and closed, the mixer is entirely concealed therein, but as soon as the can has been opened by prying off the top, and the crank has been removed from the top, it can be assembled with the mixer and the contents of the can thoroughly, mixed in an expeditious manner. Moreover, the entire construction is simple and cheaply made so that it does not add materially to the cost of the can.
From the foregoing description of an illustrated embodiment of this invention, it should be evident to those skilled in the art that various changes and modifications may be made without departing from the spirit or scope of this invention as defined by the appended claims.
