3 Claims.

The present invention relates to dredge or sifter top containers or cans and has particular reference to a can in which the sii-ter top is re.- movably'seatedwithin a friction ring opening, thev sifter top being equipped with a reenforced perforated sifter element sliding on a raised siftproof and perforated mounting.

Although numerous varieties of dredge or sifter topc'ans have been :made and marketed, considerable difficulty has been experienced more or lessin obtaining a sifter top which is sift-proof against the escape o f finely ground or pulverized materials without the use of gaskets. Ground cinnamon is; particularly hard to hold and it 'is exceedingly clifiicult and many times impossible to ship or transport" it in sifter top cansA without having the ne ,cinnamon particles sift out. The

' can of the present invention has been found to be entirely satisfactory for such difcult materials,

the sifte elementsvbeing ofv such rigidity and of such tight fitting qualities that sifting through is entirelyfprevented and this without the use of gaskets. `At the same time this sifter top can is. r

of 'simple and'economical construction.

An object of the present invention' is the pro- -V vision 'of a dredge or sifter top can which is simple in design and `economical of construction wherein the sifter top is equipped with .a movment.

able perforated sifter element rigidly reenforced against torsional stresses and held firmly and uniformly against. a lraised perforated mounting on which the rigid sifter element may be easily` mov'ed, -tofbring the vsifter perforationsof both 1- element and mounting into'alignment'f-fordis'fpensing .the contents of the can, the sliding sifter friction ring I1 having'a countersunk panel wall joint preventing escape or sifting of the contents when the sifter perforations, are in' non'jalignf Another lobject of the invention is'ft l vision of a. dredge top can having a .eilte t op of `.the character described wherein the sifter element is of dish shape and is reenforced by a continuous upright rim. extending around its periph'- ery, which imparts `strength andrlgidityk'to the.` element as a whole'and invparticular prevents torsional strains and bending of theperforated base ofthe element toinsure a better fit, the -up-l right rim also serving asa finger-hold for` moving the sifter element on its mounting.

Another object is the provision of such a' sifter perforated 'mounting vby reasonof yits beingA raised sets off areenforced atsopera'ting surface free from torsional or bending strains, the Isifter elelment being held firmly vand uniformly against top for a dredge cany wherein the raised and (ci. azi-cz) the raised mounting by elongated projections struck out from the sides of the sifter top and engaging against the top of the reenforcing rim of the sifter elementso that any stresses'set up by such engagement will not distort the base of 'i the element and/or tend to draw it away from its mounting.

Numerous other objects and advantages of the invention will be apparent as it is better understood .from the following description, which, 10 taken in connection with the accompanying drawing, `discloses a preferred embodiment thereof.

` Referring to the drawing:

Fig. 3 is an enlarged transverse section .taken substantially alongV the line 3-3 .in Fig. 2; and

Figs. '4 and 5 vare enlarged longitudinalsec- 2 tions taken substantially along the line. 4'-4 in Fig. 2. Fig. 5 showing a4 movable part of the can in adifferent position than that shown in Fig-4.-

A preferred embodiment of the present'invention is illustrated inv the vdrawing andv is incorg5.

porated ina container or can Il which is adapted .to hold ground v or pulverant material. such asD finely divided cinnamon and the like. The can comprises a tubular, rectangular shaped body" I2 having animperforate bottom closuremexiiber 30 I3 and a d redge top closure Amember generally `indicated by the numeral Il.,l The closure members are secured to the body in ner, as 'by folded lseams I S.

The dredge top closure member Il any suitable manincludes a 35' section I8 surrounded by -a substantially vertical wall' section `or rim I9. The friction'ring is per-` lseam for this purpose.

' An elongated opening. 2| ,havingstraight and. parallel sides and rounded ends is provided inA the panel' wall section I8 centrally of the friction 45 v ring I1. Thisopening is used for originally fill- -ing the can and also used by the consumer for removing its contents in b ulk form as by a spoon or other instrumentality. IThe opening is bound- Vedby a depending friction wall section 22.

A removable sifter device 25 Vfits within the elongated opening'2l of friction ring Il for closing the can after it is filled and for use-in dispensing the can contents w-ith a sifting action.

v The sifter vdevice comprises a dish shaped' memsurrounded by an upright rim or wall section 28, a small radius 23 being the connection between the wall sections. The upright wall section is of the same contour as that of the opening 2l and frictionally engages against the depending iiange 22 of the friction ring I1 when the sifter device is in place within the opening 2|. The upper end of the upright wall section 28 merges into an outwardly and downwardly bent flange 3G having a curled edge 3l whichtightly engages against the counter-sunk panel wall section I8 of ring i1 when the sifter device is in place on the can.

The bottom wall section 21 of sifter member 26 is formed with a mounting or raised wall section 33 having a iiat top surface. This raised wall section is provided with spaced sifter perforations 34. By reason of the wall section being raised, its at top'surface is reenforced and is prevented from being affected by any bending or exing imparted to or inherent in the bottom wall 21. This raised wall section is used as a mounting for a sifter element or slide 36.

25 Sifter slide 36 is also dish shaped and includes a flat bottom wall section 31 which is surrounded by a continuous substantially vertical rim 38, a small radius 39 connecting these wall sections together. The rim reenforces and strengthens the slide as a whole, particularly stiiening the bottom wall section and preventing its distortion from any outside torsional strains which may be imposed on the slide. i

The bottom wall section 31 of the sifter slide 36 seats against the top surface of the mounting 33. By reason of the elevation of the mounting no part of the bottom wall section 31 of the sifter slide engages against the bottom wall section 21 of the sifter member 26. The corner radius 39 of the sifter slide 36 is thereby held above and away from the corner radius 29 of sifter member 26 and these parts have no fitting function. This permits the bottom wall section 31 of sifter slide 36 to seat perfectly flat against its raised mounting 33. The fit therefore does not depend, as is usual upon what is likely to be an imperfect fitting together oi' corner radii. 'I'he bottom wall section 31 of the sifter slide is also provided with spacedv sifter perforations 4| for cooperation with i the perforations 34 of sifter member 26.

The width of the sifter slide 36 is such as t6 snugly fit within the sifter member 26, its rim 38l being in sliding engagement with the upright wall section 28 of the sifter member. 'I'he slide is shorter than the sifter member in order to allow space for relative sliding movement.'

The slide 36 is retained in sliding position on top of its raised mounting 33-by elongated beads or lugs 45 which are preferably struck out from the upright wall section28 of the sifter member 26. These beads are located in the straight portions of the wall section and project inwardly, extending over the top of the slide 36 on opposite sides thereof. The beads engage against the top edge of the continuous reenforcing rim 38 of the slide and exert a pressure on the latter to hold it firmly against the top of the raised mounting 33. 'I'hus any strains set up by this pressure are absorbed by the rim 38 thereby leaving the bottom wall section 31 free from distortion and perfectly flat against its mounting.

By pushing against the vertical rim 38 of the slide 36 the latter may be slid across the top of its raised mounting 33 into different positions as shown in Figs. 4 and 5. When the slide is in the y, 2,li78,093 ber 26 having a bottom wall section 21 which is4 position shownin Fig. 4 the sifter perforations all, il of the mounting and the slide are in alignment so that the contents of the can may be readily dispensed with the usual sifting action. When the slide is shifted to the opposite side of the sifter member as shown in Fig. the sifter perforations 34, il are out of alignment and the can is closed against sifting.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing'from the spirit and scope of the invention or sacrificing all of its material advantages,.the form hereinbefore described being merely a preferred embodiment thereof.
