6 Claims.

The present invention relates to dredging cans and has particular reference to a fully sealed can which is opened by breaking out of scored parts, such a can being provided with a sliding member of simple construction and one which is retained in a unique manner on the end of the can so that it functions selectively to close v the can after it has been opened or to expose certain of its openings for dispensing purposes. An object of the invention is the provision of a sealed dredging can which is provided with a sliding member retained in sliding condition within the seat or panel of an imperforate can end that is perforated to open the can, the retaining means being flattened beads struck out as integral parts of the can end wall which hold the slide against displacement and at the same time allow for its free manipulation to cover and uncover the perforations.

Anotherjobject of the invention is the provision of a sealed rectangular dredging can having a sliding member which is movable back and forward to cover and uncover pouring and sifter openings which are made in a wall of .the can when it is opened, the can wall being provided with opposed beads for guiding the slide in its movement, flattened sections of the beadsbeing used to retain the slide in operative condition.

Another object of the invention is the provlsion of a dredging can ofthe character described wherein the sliding member is provided'with 1ocating means for accurately positioning it for closing of both pouring and sifting openings or for selectively uncovering either of them.

A further object of the invention is the provision of a round sealed dredging can having an imperforate end formed with a circular sunken panel or seat outlined by a peripheral bead or rim for the reception of a rotatable slide member, the latter being retained against displacement by flattened sections of the circular bead which overhang the peripheral edge of the slide, the position of the slide member within its seat determining the type of dispensing action'for the can contents, afteropening of the can by perforating its end, or effecting a closure for all. of the openings in the can end wall.

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:

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

Fig. 2 is atop plan view of the same;

Fig. 3 is a plan view of a round can embodying the present invention;.

Figs. 4 and 5 are longitudinal sectional views 5 taken substantially along the line 4-4 in Fig. 2, Fig. 4 illustrating the .can prior to its opening and Fig. 5 showing the same after opening; and

Figs. 6 and '7 are transverse sectional views taken respectively along the lines 6--6 and 'l| 10 in Fig. 2.

The present invention is concerned with a dredging can having a sliding closure member and Figs. 1, 2, 4 to '7 inclusive illustrate the invention as it is applied to a rectangular can while Fig. 3 illustrates the application to a round can,

Considering first the rectangular form of can the drawing illustrates a rectangular body ll preferably formed of metal provided with an imperforate bottom or end member l2 and an imperforate metal top end member l3. The member l3 may be secured to the upper end of the body II in the usual double seam M.

The top end I 3 of the can is of the usual sunken panel or dished form required for double seaming with a surrounding panel wall l5 which is at right angles to a web wall l6. A'second sunken panel I1 is formed in the end panel wall l6 and its outer edges are substantially parallel to the boundary Wall l5. On two opposite sides of this panel within a panel, the web wall I6 is beaded as at l8 (Figs. 2 and '7) to provide a pair of opposed beaded rims.

The bottom part of the panel I1 is flat and this section- (designated by the numeral 2|) is partially cut through in score lines 22. The metal within the score lines is adapted to be pushed down and inside of the can as an incident to opening the can and a pouring opening 23 and sifter openings 24 are thereupon formed as best 40 illustrated in Fig. 5.

A metal slide member 3| is provided for sliding engagement with the flat panel wall 2| and is located within the panel II. It has its opposite edges in sliding engagement between the upstande ing bead rims l8 formed in the can end wall. At intervals the bead rims are flattened to provide retaining lugs 32 which extend in and overhang the longitudinal edges of the slide member. These retaining lugs hold the slide member against displacement from its panel seat and at the same time allow for a free although restricted I longitudinal movement.

The two ends of the'slide member 3| are curled to provide finger pieces 35 and these permit easy manipulation of the slide back and forth within its panel seat. Prior to opening of the can the slide has no utility, as the imperforate top before perforation acts in its capacity to seal the contents. After the

openings

23, 24 are formed the slide functions in accordance-with its position within its panel seat.

When the slide member 3| is in its central posit-ion both the pouring opening 23 and the sifter openings 24 are covered and in this position the slide acts as a. closure for the can. When the slide member is moved toward the right (Figs. 1, 2 and 5) the sifter openings 24 are uncovered and a sitting of the contents may be had through the sifter openings. When the slide member is in the opposite end of its, seat, the sifter openings 24 are covered but the pouring opening 23 is uncovered. The can contents may then be dispensed through the latter.

The flat slide 3| may be reinforced by an oblong bead 36 which is struck up from the met-al and a central button 31 is also preferably pressed in the metal of the slide just inside of the oblong bead. This bead 36 in addition to strengthening the slide is utilized, as is also the button 31, in a locating stop capacity as will now be further explained.

The fiat wall 2i of the recessed can top is pressed up at its center into a button 38, best illustrated in Fig. 4. This 'button cooperates se lectively with the two ends of the oblong bead 36 or with the button 31 in locating the slide in one of its three positions. The button 31 of the slide engages with the can end button 38 when the slide is in its central or can closing position, In the other two positions of the slide, the button 38 snaps into one or the other ends of the bead 36 and in like manner definitely locates the slide in its pouring or sifting positions.

In the adaptation of the instant invention to a round can, the circular end (designated by the numeral, Fig. 3) is formed with a circular depression or panel 42 which in this form is preferably surrounded with a circular bead rim 43. A rotatable slide member 44 is herein provided and is located inside of the surrounding bead rim 43. This beaded rim is flattened at spaced intervals' as at 45 to provide retaining lugs which overhang the periphery of the rotatable slide 44 and keep it in its seat while permitting free rotation.

The wall of the end inside of the sunken panel 42 is partially cut through in an oblong or kidney shaped score line 46 and inseveral circular score lines 41. The sc res are broken through and the metal of the end inside of the score lines is pushed into the .can in the same manner as before when the can'is opened. This displacing of the metal provides a pouring opening 48 and sifter openings 49.

The rotatable slide 44 is also formed with a kidney shaped opening 5| and when this is brought into register with the pouring opening the can contents may be dispensed therethrough. In like manner a registration with the sifter openings 49 permits sifting of the can contents. When the slide opening 5| is out of register with either the pouring or the sifter openings the slide functions as a closure for the opened can. A finger piece 52 struck up from the slide wall or attached thereto provides for easy manipulation of the slide to rotate it into its several positions.

It is thought that the invention and many of its attendant advantages will be understood from the foregoing description, and it will be apparent -lined by score lines cut in said panel wall, the

metal within the score lines being adapted to be pressed inside of the container to open the same,

a slide member located inside of said sunken panel and having a thickness substantially equal to the depth of the latter, said slide member having an edge adjacent said beaded rim, the latter being flattened at spaced intervals to provide retaining lugs which project over said slide edge and slidably retain the slide in its seat so that it is movable into different positions to cover both pouring and sifter openings or to selectively cover only one of said openings.
