INsE'r srr'rnn 'ronv Application led lSeptember 16, 1921. Serial No. 501,042.

To all whom it may concern:

Be it knownA that I, JOHN I-I. KLINGSTTNE, a citizen of the United States, and resident of Baltimore, Maryland, have invented certain new and useful Improvements in Inset Sifter Tops, of which the following is a specification.

My invention relates to containers, and 1s especially directed to an lmproved type of sifter top therefor. A general obJect of my invention is to provide a top of this nature includingthe usual dispensing perforations and a' manually operated slide cover therefor, which is extremely simple both in arrangement and construction, with the purpose of providing a strong, positive acting slide and a top which can be very cheaply and rapidly manufactured by standard types of machinery. v

My invention is particularly directed to the provision of a sifter top including a cover of the inset type. In containers-employing sifter tops, it is highly desirable to provide for ease in filling comblned with a cover tight enough to prevent the .escape of even the linest powder; andthe friction inset type of top is admirably suited for this pu ose, both because of the facility with which a large filling opening -is provided, and the tightr closure `which the employment of this kind of top assures.` I-Iowever, the ordinary sifter top construction is not readily `applicable to inset covers, constructions heretofore suggested for the purpose being cumbersome and impractical.

Another important object of my invention, therefore, is to provide an inset friction cover for containers, embodying in the cover a dispensing perforation or perforations provided with a sliding closure.

As covers of this type may be of substantial size, and ordinarily are somewhat larger than the usual perforated tops of dispensing containers, an ancillaryI object is to provide a slide closure which will operate eiiiciently and can readily be manufactured for use in a dished top of substantial size.

Other ob'ects and advantages of my invention will be apparent from the following description, taken in connection with the accompanying drawings, in which:

Fig. 1 is. a perspective view of a container embodying my invention,

Fig. 2is a. vertical transverse section' through such container, and y Fig. 3 is an enlarged fragmentary vertical section through one side of the cover and slide.

' My invention is illustrated as applied to a container 10 of the full opening type, provided with straight sides terminating at the top in an outwardly extending bead 11. The cover 12 is of the inset friction type having a bottom 13, side walls 14 adapted to fit tightly against the walls of the container 10, and an outwardly turned bead 15 overlying bead 11 of the container body when the cover lis in closed position. This type of cover, often called a friction to is well known; and it is Aapplied to various types of containers in various ways, to all of which my invention may readily be adapted.

I provide a dispensing perforation or perforations 16 in the bottom 13 of the cover, preferably extending over half or less of its area. In connection therewith, I provide a closure plate 17 mounted to slide along the bottom 13 of the cover into position to close or expose the apertures 16, the plate and bottom being so contoured that when in closed position the plate will fit snugly Aagainst bottom 13, to prevent escape of any substantial amount of the container contents.

A principal feature of my invention includes .the means for mounting plate 17 in the cover. For this purpose I provide walls 18 extending upwardly from and preferably integral with the cover bottom 13. These walls form guides between which the plate 17 slides; and preferably constitute the' lower 'portion of cover wall 14. Where the cover slides in a longitudinal rather than a rotary manner, as in the preferred form illustrated, I employ two parallel walls 18, vwhich in the simplest form are constituted from the lower part of walls 14 of the cover. Plate 17 extends into proximity to the walls 18 so as to be guided thereby.

I also provide means for retaining plate 17 in close enga ement with the cover bottom 13 without interfering with the sliding of the plate. For this purpose, I provide inward projections on walls 18 extending above and in position to engage the upper part ot plate 17. These projections are conveniently produced byvdirecting an extension ot' said walls 18 inwardly, immediately above the edges of plate 17 throughout all or a part of the active guiding portion of said walls 18. there walls 18 are part of the cover walls, this is readily produced by striking inwardly a bead 19 along each of the guiding walls of the cover; but obviously the guide grooves termed by walls 1S and beads 19 may be produced in the cover walls in various other ways within the skill of' an ordinary mechanic.

I preferably provide means for facilitating the manual operation of slide plate 17, as by connecting to or forming from said plate an upwardly' projecting tongue '20, which maybe rolled over as illustrated, to produce a neatI and attractive finger piece. 4`urthermore, this construction considerably stiifens plate 17 transversely, and tends to prevent it from bulgingor becoming bent upwardly away from the dispensing openings 16. Moreover, it desired the parts may be so proportioned that plate 17 will be very :lightly curved downwardly by the lateral iressure thereon of walls 18, holding said plate in close contact with the cover bottom 13.

It will be apparent that covers constructed' according to my invention may be very readily and rapidly manufactured, particularly in the general form shown 1n the drawings,'in which the only additional operations necessary on an ordinary inset friction top are the reduction of the perforations 16 and striking up the retaining means 19. Plate 17v isequally simple to manufacture, since it may be made from a single sheet by a simple stamping operation. Furthermore, the cover and slide plate may very readily be assembled, either b v locating plate 17 on the cover bottom and then striking u the retaining means 19, o-r by forming saiil retaining means in the cover during its regular manufacture, and then utilizing the resiliency of ordinary sheet metal to spring plate 17 into place, the latter operation being particularly effective when such plate is so proportioned that it is normally curved downwardly to some extent, as above indicated. It is of course understood that various other methods of assembly, depending upon the precise construction used, may be employed, my intention being simply to indicate the ease of manufacture and assembly of the preferred form shown.

It will be apparent that numerous variations in my invention can readily be made, 'both in the arangement of the guide and retaining means and in the construction of the slide plate. In particular, while I have disclosed a longitudinally sliding plate, my invention is not necessarily limited thereto, as a rotating plate can be employed in an embodiment of my invention by any skilled mechanic.

My invention therefore is not limited t0 the precise form shown. or the modifications therein indicated herein, as numerous other changes and variations therein can readily be made by one skilled in the art within the scopo of the following-claims.

I claim: y

1. dispensing closure for receptacles of the full opening type having straight side walls and designed for granular or ulverized material, comprising a disherl sheet metal body having a substantially' fiat bottom portion co-extensive with the mouth of the receptacle in which the closure is to be inserted, said bottom portion having one or more dispensing openings, upright side walls surrounding said bottom portion and adapted to tit closely, within the upper ends of the side walls of said receptacle with said bottom portion located below the up(per edges ol said receptacle side walls, an a cover piece slidably located on the outer face of said bottom portion with two opposite edges close to two opposite side walls of the closure, the length of the cover in a direction parallel to said edges being substantially less than the length of said closure bottom in the same direction, said closure side walls having impressed beads near the closure bottom andcngaging over said parallel edges ofthe cover member to retain the latter slidably in position.

2. A dispensing closure for containing receptacles of the full opening t pe having straight side walls and designedy for finely divided material, comprising a dished sheet metal body having a substantially flat bottom portion co-extensive with the mouth of the receptacle in which the closure is adapted to be inserted with a push fit, said bottom portion having a pattern of dispensing openings near one side thereof, upright side walls surrounding said bottom portion and adapted to tit closely within the upper ends of the side walls`of said receptacle with said bottom portion located below the upper edges of said receptacle side walls, a cover piece slidably located on the outer face of said bottom portion with two opposite edges close to two opposite side walls of the closure, the length ot the cover in a direction parallel to said edges being substantially less than the length of said closure bottom in the same direction, said closure side walls having impressed beads near the closure bottom and arranged to engage over said arallel edges of the cover member to retain the latter slidably in position, and a handle on the cover.

3. A container comprising e body of the full opening: type having straight side Walls and :in inset top or closure fitting frictionally between tbe side walls and Consisting of a bottom and side Walls, and perfol'ate at one end of the bottoni, and a sliding cover, opposite side walls of the closure at the top offset inwardly to provide guides for the cover to hold it close to the bottom of the top, said offsets being below the tops of the side Walls.
