closed against any sifting of the contents, all by the proper positioning of the various elements in the'sliding unit.

An object of the present invention is the pro- 15, vision of a dredging can which is initially sealed on its contents and which may be opened to maize efiective a duplex sliding closure unit of simple construction, being a slide within a slide, such an opening unit conditioning thecan for reclosing or for difierent Ways of dispensing.

A further object of the invention is the provision of a reclosure unit which has different positions in a can top and which can be moved as desired under a simple sliding action to permit full open dispensing or dredge and sifting dispensing, the unit including a supplemental slide element having independent sliding movement within the slide unit to'reclose the can when desired.

3o. Numerous other objects and advantages of the invention will be apparent as it is better understood irom the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawing:

Figure 1 is a perspective view of a dredging can embodying the present invention;

Fig. 2 is an exploded perspective view of the parts comprising the reclosure unit, dot and dash line indicating the relationship between the parts;

Figs. 3, 4 and 5 are top plan views of the can showing various positions of the reclosure unit;

Fig. 6 is a transverse section on an enlarged scale through the upper end of the opened can and showing the can reolosed; and

Fig. '7 is an enlarged longitudinal section of the same can arrangement as in Fig. 6 with the central portion of the can broken away.

0' The present invention is concerned with a dredge can having a duplex sliding closure element which only becomes effective after the can has been opened and the drawing illustrates a rectangular shape of can by way of example. It

comprises a can body ll preferably formed of metal and pro ided with an imperforate bottom or end member l2 and a top end member it. A conventional double seam I l may be used to secure these parts'together.

The top end I3 is primarily of the usual sunken '3 panel or dished form required for double seaming and is further countersunk in a central rectangular depression l5 which provides the seat for the duplex reclosure unit, generally designated by the numeral it. A semi-circular score line it (Figs. 2 and 4) is out in the panel wall of the depression l5 and at opposite sides this line merges into an interrupted score line 22. Such score lines may be mere weakened places or they may be cut entirely through the metal of the top,

such metal being then-pressed back into the original plane occupied.

The score lines 2i, 22 set off a removable section 23 which may be displaced from its panel position, as shown in Figs. 6 and 7, to provide a dispensing opening 25. In such an opening of the can, the can wall is bent along the broken line 22, the removable part being pushed into the can. Before such opening of the can, the panel wall of the depression l5 is smooth and may be considered as imperforate as far as holding the contents of the can.

The duplex reclosure unit it comprises a slide within a slide and is made up of two separate pieces. One of these is a lower fiat slide memtill ber 27 (Figs. 2 and 7) which is longer than the longer dimension of the top depression 65. its terminal ends 28 extend into grooves 29 pressed outwardly from the end walls of the panel depression. These grooves provide slideways for 53E) the slide member 2'1, overhanging shoulders 3i being thus formed in the depression end Walls when the grooves are produced. These shoulders extend over the ends of the slide member ill and prevent any slide displacement while allowing the slide free movement laterally of the can top.

Partially open curls 33 are formed at the sides of the slide member 27. This strengthens the slide, holds it fiat so that it tightly engages the can top panel surface in any position that the as slide unit may occupy and also provides finger holds to make the manual movement easier. Slide 21 is also cut through with perforations 3 which in the present embodiment of the inven- -tion are spaced from each other and are located so along the longitudinal center line of the slide member.

The second part of the slide unit it is a supplemental slide element 35 which is shorter than the length dimension of the panel depression i5.

This supplemental slide is engaged with the slide member 21 and has longitudinal sliding movement relative to the lower slide. For this purpose the longitudinal side edges of the slide element (as at 36 in Fig. 6) extend into and are slidably held by the curls 33 of the other slide memb'er.

For ease of assembly the slide element 35 may be inserted from either end of the slide member 21, the edges 36 easily entering the partially open curls 33 and this is done before the reclosure unit I6 is assembled in the can top.

Slide element 35 is also out through by a series of perforations 31 which extend along the longitudinal center line of the element. The perforations are of the same size and are spaced at the same interval as the perforations 34. To make easier the'longitudinai movement of the slide element within the slide member 21, finger holds are provided at the ends of the element, these being more curls 38 formed in the ends.

When all of the can parts are assembled the slide member 21 of the reclosure unit i6 rests in close sliding position on the panel wall of the can top and the supplemental slide 35 rests in close sliding position on the slide member. This reclosure unit is in the position shown in Fig. 3 when the filled can is received by the ultimate consumer. The can is fully sealed at that time.

To open the can, the reclosure unit is moved laterally of the can top into the position of Fig. 4. In this position the scored lines 2|, 22 are uncovered and the can may be opened by pushing in the removable section 23 bending the metal along the score line 22 and producing the discharge opening 25. The can is then in full open position and the desired amount of contents can be poured out or may be easily removed by insorting a spoon or other implement into the can through the discharge opening. The shape of the discharge opening lends itself to such procedure.

\''hen the can is to be reclosed, the reclosure Illlil I6 is again moved back to the other side of the L in. This covers the discharge opening. The sliding element 35 is toward the right (Figs. 3, 4

and 'i) at such time and when in this position its perforations 31 are out of alignment with the perforations 34 of the slide member and the can is fully closed against sifting of its contents.

If a dredge or sifter dispensing is desired it is merely necessary to move the supplemental slide element 35 into the position shown in Fig. 5.

This brings the

perforations

34, 31 in alignment. These perforations, when the slide parts are so placed, are over the open discharge opening 25 and therefore there is free access for the contents to be 'dispensed through the aligned perforations.

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.

I claim:
