CAN-COVER OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 581,293, dated April 27, 1897.

Application filed September 25, 1896. Serial No. 606,939. (No model.)

To all whom it may concern.-

Be it known that I, CLINTON H. LEGGETT, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Can-Covers or the Like, of which the following is a specification.

This invention relates to covers for cans, and aims to provide certain improvements in such devices especially applicable to those covers which are irrernovably fixed to the can, as, for example, those employed for chlorid-of-lime cans, seed and cereal boxes, and the like.

The invention aims to provide a simple, cheap, and compact cover which will serve to make a tight closure and can be readily opened to expose an aperture leading to the interior of the can.

To this end the invention provides, in addition to the usual can top, wall, or cover having an aperture, a supplemental top or 'wall having an aperture coinciding with that in the usual top, having a flange entering the latter aperture and riveted or pressed against the inner face of the usual top and thereby united thereto by a leak-tight joint, which supplemental cover has suit-able holding and guiding provisions and carries a movable or sliding cover which can be moved to open or close the aperture.

The invention also provides an improved combined metal and paper cover and certain improvements in details of construction of the parts, all of which will be hereinafter fully set forth.

In the accompanying drawings, Figure l is a perspective view of a can having a combined metal and paper cover embodying the preferred form of my present improvements, the parts being in the closed position. Fig. 2 is a fragmentary perspective View thereof, the parts being in the open position and the interior of the can exposed through the aperture. Fig. 3 is a fragmentary axial section thereof, the parts being in position shown in Fig. 1. Fig. 4 is a perspective View of the supplemental cover alone and inverted, showing its condition before application to the usual cover. Fig. 5 is a perspective view of the sliding cover alone and inverted. Fig.

6 is a plan, and Fig. 7 is a fragmentary axial section showing a modification. Figs. 8 and 9 are like views showing another modification.

Figs. 10 and 11 are like views of still another modification. Figs. 12 and 13 are like views of still another modification. Figs. 14: and 15 are respectively a fragmentary plan and an axial section showing still another form of supplemental cover and movable slide, and Fig. 16 is a perspective view showing a paper cover with a modified form of supplemental metallic cover and slide.

In the modifications shown in Figs. 6 to 13, inclusive, the parts are all made of metal, while in the construction shown in Figs. 1 to 5, inclusive, and in Fig. 16 the usual cover is made of paper and the supplement-a1 cover and slide are made of metal.

Referring to Figs. 1 to 5 of the drawings, I will first describe in detail the preferred form of my invention-as therein shown. In this construction A is the can-body, B is the bottom thereof, and O is the top wall or usual cover thereof. Preferably the cover 0 is constructed with a flat smooth middle wall a, depressed below the surrounding portion of the cover, surrounded by a rise or shoulder 6, extending upward to the top 0 of the cover, which extends outwardly in any form to the flange d, the wall being provided with an aperture 6, preferably eccentric of the cover and affording an opening through it. On the wall a is seated and fixed an auxiliary cover D, which carries a movable cover E. The cover D has an aperture f, coinciding with the aperture e and affording communication through the usual and additional covers, and has a flat bottom g, surrounding this aperture and extending along the walla of the usual cover. The additional cover D is formed with a downwardly-extending flange h, passing through the aperture e, which flange has an outturned edge t', bent or pressed against the inner or bottom face of the wall a with sufficient force to make a leak-tight joint between the usual and additional walls or covers. The additional cover has inturned side and end edges j at three sides, beneath which is a track or slideway 76, within which slides and fits the movable cover E. The movable cover is a substantially flat plate of sufficient length and width to cover the aperture f and fit within the tracks is, which tracks are long enough to permit sliding of the cover backward until it completely exposes the aperture. The sliding cover has a thickened handle portion F, preferably formed by two cars, the one, Z,being cut partly out of the body of the cover and turned outward on the top face thereof, and the other, on, being a projection on the rear end of the cover, folded up on top of the ear Z, by grasping which the cover can be moved toward and from the open position at will.

To facilitate grasping the handle F with the ends or nails of the fingers, the additional cover D is constructed with a space or slot at in its outer end, which extends from its end nearly to the aperture f, thus leaving a small space below the handle F, as shown.

To obtain an elastic pressure of the sliding cover over the aperture, the former is preferably constructed with a slight downward convexity or partly-spherical portion 0,which in the closed position lies over the aperture f and presses against the edges of the neck or flange h, being prevented from rising by the engagement of the edges j with the top face of the slide. This convexity also serves to resist danger of accidental opening of the slide.

The depression of the wall a of the usual cover is preferably suificient to bring the additional cover and the sliding cover below the top 0 of the usual cover, so that the cans can be packed and handled without danger of injury or displacing the slide.

When desired as an exceptional protection against leakage, a thin slip of paraffin-paper G can be placed beneath the sliding cover E with its edges folded over the edges of the latter, as shown, thereby making an extremelytight joint. hen the cover is slid back, this paper can be broken, as shown in Fig. 2, or it can be removed from its position in any suitable manner.

I prefer to make the cover 0 of pressed paper or other fibrous material; but, if desired, it may be made of metal or any suitable material. The additional cover D and sliding cover E are preferably made of metal, being stamped and bent into the desired form and shape. hen the usual cover is of paper, the flange h of the additional cover protects the edges of the paper at the aperture. The additional cover reinforces the body of the paper cover and gives a suitable strong holder for the sliding cover.

It will be seen that my invention provides improvements in covers which can be readily and advantageouslyavailed of for various constructions of can and other covers; and it will be understood that the invention is not limited to the particular details of construction and application set forth as constituting the preferred form of the invention, but that these can be modified as circumstances or the, judgment of those skilled in the art may dictate without departing from the spirit of the invention.

In the modification shown in Figs. 6 and 7 the cover 0 is a fixed metal cover seamed onto the can-bodyA, and the additional cover D is circular in form, covering the major portion of the fixed cover and having upturned earsj, beneath which'slides the sliding cover E, the edges k of which are folded inward at the sides where they pass under the ears j and at the end where they serve as the handle F. In other respects the fixed cover has an aperture cand the additional cover an aperture f and a flange h, the edge 7 of whichis turned inward against the inner face of the fixed cover. No convexity of the slide is shown in this construction nor is any paper interposed.

The construction shown in Figs. 8 and 9 comprises a fixed metallic cover 0", to which is applied an additional cover D, having a neck or flange h passing through the aperture c in the fixed cover and having an outturned edge 1' embracing the under face of the latter, to which additional coveris secured by a rivet H a movable cover E, which swings on the rivet H toward and from the aperture f. The movable cover at its end and side passes under earsj on the fixed additional cover, and at its outer side has a handle F, formed by its overturned edge.

The construction shown in Figs. 10 and 11 comprises a fixed metal cover 0 on which is fixed an additional cover D which has side flanges j embracing sliding cover E having a handle F formed by overturning the outer edge of the cover. The additional cover D as with the other forms described, has an aperture f, a neck h, passing through the fixed cover, and a flange ti, pressed against the inner face of the latter.

In the construction shown in Figs. 12 and 13 the usual cover 0* is a fixed metal cover, on the top of which is fixed a circular additional cover D which has ears 7' turn ed up from its body on two sides, under which ears swings the movable cover E, which is pivoted to the additional cover by a rivet H, and has a projecting handle F formed by turning up a projection on its free side. The additional cover here has an aperture f coinciding with the aperture 6 in the cover C, and is fixed thereto by a tubular or eyelet rivet I, having a neck h extending through the fixed cover and edges 1' at top and bottom pressed against the outer face of the cover D and against the inner face of the cover 0 and binding them together with a leak-tight joint protecting the edges of both. The cover E bears on the top of the rivet I.

In the construction shown in Figs. 14 and 15 the additional cover D is a disk-shaped metal plate having an aperture f ,which coincides with the aperture 6 in the usual wall 0, and is closed by a movable cover E which is composed of a sheet of metal folded upon itself at its edges, the wall 0 havinga flange 72/ passing through the aperture f in the cover D and having an edge 4; pressed against the outer face of the latter, the cover E having its outer edges 3 of its sides bent underneath itself and sliding under the edges 7' of the cover D In the construction shown in Fig. 16 the cover 0 is a pressed paper cover, on the top of which is fixed a substantially circular metal disk constituting the additional cover D, which has an aperture f, a flange h, passing through the paper cover and riveted against the inner face thereof, flanges q q, cut from the body of its sides and folded inward over the sliding cover E", a similar end flange r for arresting the latter, and a recess 8, providing a space for the handle F of the sliding cover, which in construction is substantially identical with that described with reference to Figs. 1 to 5, except that it is devoid of con- VeXity.

It will be understood that the word cover as herein used includes any wall or envelop of any casing or receptacle and that the improvements herein described can be applied to any such wall or envelop where desired and according to such construction as is best suited to the contents of the package or the manner of its removal. The invention can be readily employed for such packages as the oblong closed paper boxes used to pack cereals or seeds and for other purposes, the aperture being made large enough to permit removal of the contents through it with a spoon, if desired.

It will be seen that the joint between the usual wall or cover and the additional wall or cover is an important feature of improvement. This joint is in the nature of an eyelet or tubular rivet, which utilizes the necessary apertures through the parts to traverse the latter and bind the parts together with a firm and leak-tight joint, thus avoiding. any puncturing or attachment elsewhere than that surrounding the aperture. This tubularrivet connection serves to protect the edges of the wall and additional cover and to give a smooth, round, and strong edge surface for the aperture f, as well as a suitable flat hearing edge for the sliding cover. It can be formed rigidly in any of the three ways illustrated, either by making it as an integral flange with the additional cover, or as a separate eyelet, or as an integral flange with the usual cover or wall.

The additional cover and sliding cover constitute an attachment for application to a box or receptacle and can be sold in the form shown in Figs. 4: and 5 for this purpose, the flange h being ready to enter any hole which may be cut to fit it, whereupon its inner edge 2' can be turned outwardly against the inner face of the wall through which the hole is cut.

It will be seen in Figs. 2 and 3 that the shoulder b, surrounding the wall a, acts'as a stop in the path of the slide E and prevents escape or undue withdrawal thereof.

When the additional plate and its sliding cover are used for attachment to any wall, the flange h can, if desired, be replaced by the tubular rivet I, (shown in Figs. 12 and 13,)

which can be loosely set in the aperture f in the additional wall and can be passed through any aperture which may be provided for it in the wall to which it is to be applied, whereupon by compressing the upper and lower flanges of the rivet against the two walls the attachment can be firmly fastened in place and its slide used to open or close the aperture through the rivet.

I prefer to make the additional cover or wall D of thin sheet-zinc, which metal is stamped and bent to form the riveting-flange h and the tracks or guideways j, and has certain antifriction properties and sufficient flexibility so that in case of undue creasing of the flanges forming the tracks the sliding cover E is still comparatively easy of movement from the closed to the open position.

The advantage of interposing the paper G in constructions where the interior of the can is coated with rosin, paraffin, or other material before filling is that the paper acts to prevent adhesion of the coating with the slide. Such adhesion might necessitate the use of considerable force to open the slide. Consequently in lime-cans or others so coated in ternally I prefer to use the paper, which keeps the coating away from the sliding cover, so that the latter can be easily opened, and then the paper and the coating on it opposite the aperture can be broken, as shown in Fig. 2, to cause access to the interior of the can. Cans of this construction are generally filled from the bottom, the bottom cover being seamed or soldered on after filling. The inside of paper cans or boxes is usually lined with rosin applied while hot, in which case the interposition of the sheet of paper G is especially advantageous. In other cases, as, for example, when a metal can and cover are employed and the can itself is sufficiently tight, a perfect sealing can be made by'sim ply applying a thin coating of paraffin or wax to the inner face of the slide after the latter has been closed, making this application with a brush or otherwise through the aperture ffrom the inside while the can is inverted and before it is filled or its bottom applied.
