Claims. (Cl. 222480) The present invention relates to dredging cans for powders, condiments and the like and has particular reference to a fully sealed rectangular double seamed can which is opened by breaking out scored parts cut in a central panel of thecan end or top, this panel being raised flush with the top part of the seam to provide a slide seat for a perforated top slide which engages over two opposite sides of the seam by means of which the cam may be fully opened for dispensing of its contents as in removal by a spoon, or the dispensing may be done by sifting the contents through the perforations or dredge openings in the slide, or the can may be reclosed by the slide against any discharge of the contents.
An object of the present invention is the provision of a double seamed dredging can which is initially sealed on its contents and which may be opened to make eifective a perforated top slide which engages over the double seam and slides along and in close contact with a raised central panel of the can end, different positions ofthe slide determining different kinds of dispensing of the can contents in addit on to functioning as a reclosure for the can.
Another object is the provision of a simple flush top slide member for a rectangular can of the character described which allows for removal of a large amount of the contents as by a spoon when the slide is moved toward one short edge of the rectangular can top and which closes the can when the slide is moved toward the other short edge, at which time it is centralized on the can top, dredge openings being effective at termediate position of the slide.
Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.
Referring to the drawing:

Figs. 5 and 6 are longitud nal and transverse sections taken respectively along the section an inlines 55 and 6-6 in Fig. 4 and drawn to an enlarged scale.
The present invention is concerned with a dredging can having a simple one piece perforated top slide which has longitudinal movement across a flush surface provided in the can top, which is secured to the can body in' a double seam. The slide becomes efiective to condition the can for dispensing of or for enclosing its contents, after' the can has been in'tially opened, by breaking out or depressin a scored part of the top end. Such a can is preferably rectangular in shape and the slide member is also rectangular and two sides of the'slide are engaged over and under the double seam joint. connecting the can and body.. This holds the slide in proper position relative to the can top.
Such a rectangular can comprises a can body I I (Figs. 1 and 5) preferably formed of metal and provided with an imperforate bottom or end member l2 and an imperforate'top end member [3. The two end members maybe secured to the body in conventional double seams It.
The top end I3 is primarily of the usual dished form required for double seaming but the-central panel, designated by the numeral I5 is raised or extended to a position where its upper surface is flush with the top edge of the seam. l4 thus leaving the usual depressed wall adjacent'the double seam as an annular chuck groove l6.,
7 The flush surfaces of the central panel l5 and the seam !4 permit the use of a one-piece top slide member l1 which rests on the panel wall and on the double seam in various positions of the'slide. To insure a simple and eifective'slid ing connection for the slide member I l, the same is bent down along its two long sides or opposite longitudinal edges in curled flange edges i8 which snugly fit over and under the outside surfaces of the two opposed seam parts on the long sides of the can end l3. This is best shown in Fig. 6.
The natural spring of the metal insures a close contact and pressure engagement between the lower surface of the slide and the upper "surface of the panel in the different positions of the slide and makes a simple and at the'same time an efli cient dredge can construction.
The can top 13 is cut through fully or in part by score lines 2| (Fig. 3) which preferably are patterned as a continuous arc as a broken chord line setting oil a removable area 22 which for this design of score lines is the segment of a "circle; This removable area is containedfully within the central panel prior to openingof the can and thus provides an irnperforate can top for enclosing the contents.
When the can is opened to render the slide l'l effective as a slide closure member, the segment area 22 is pushed down into the can as shown in Fig. 6, the arcuate score line breaking through and the metal of the top bending along the chord score line. This removal of the area 22 from the plane of the can top creates a dispensing opening 23 in the can top.
The slide H, which becomes effective upon this initial opening of the can, is out through adjacent one end with perforations 24. The pres- -I ing lesser slide movement. This compact feature 7 is highly desirable in dredging cans.
ent embodiment shows these holes asarranged I along an arc line so that they will more correctly align with the dispensing opening 23 along its curved side when such perforations are used as dredge or sifter openings.
A notch 25 is also cut into one end edge of the slide I1 and is preferably positioned close to one end of the line of perforations. This notch is used for alignment with the dispensing opening 23 when the slide is in one position and allows for more compact and minimum dimensions of the can with the maximum size of dispensing opening.
The slide I! has three positions relative to the can top l3 and at each position a different dredge can condition obtains. Elements in the slide'it self insure exact positioning of the slide for its different dredging functions. Thus when the sealed can is first received by the ultimate consumer of the contents of the can the slide I? is centered directly over the cantop, as shown in Figs. 1 and 2. This is also the reclosing position of the slide after the can is opened and when it is again closed.
In this centered position the proper alignment is determined by a downwardly extending stop curl flange element 26 which strikes against the double seam along one short edge. This stop curl is merely an angular extension of the two side curls l8 along the back edgeof the can top. In the same position a protuberance 21, pressed in the wall of the slide adjacent its rear edge, rests inside of the double seam.
The slide I! is moved to other positions by manipulation of a finger curl 28 which is cut out of the flange curl 26 and is curled up over the top of the slide. To first move the slide, therefore, in preparation for its initial opening it is merely necessary to draw it back across the top of the can into the position of Fig. 3. In doing this the protuberance 2'! snaps over the seam. In withdrawn position, sides of the notch 25 of the slide match or register with the score lines at the end of the scored section and all of the removable area 22 is thereupon exposed.
Protuberances 3| pressed down fromthe slide wall are now engaged against and inside of the double seam at the rear edge of the can top. This forms the stop elements for this position of the slide. While in this position the can is initially opened by pressing'in the removable area as previously described. After opening of the can and while the slide is still in this position dispensing of the can contents may be had by inserting a spoon into the dispensing opening 23, the shape of this opening being designed for such dispensing action.
The sifting position of the slide I1 is shown in Figs. 4 and 5. To reach such an intermediate position, the slide is pushed forward until protuberances 32 are snapped over and brought just 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.
