2 Claims. (01. 220-41) the body I is slidably mounted a cover I9 also This invention pertains to boxes of the type commonly used as containers for medicinal tablets or the like and comprising a relatively shallow body equipped with a sliding cover.

One object of the inventionis to provide a sheet metal box of the character indicated which is of an improved construction characterized by the absence of sharp edges likely to injure the user.

Another object is to provide an improved slide cover box in which both the body of the box and the cover are provided with marginal protective beads formed to provide cooperating stops for limiting the extent of sliding movement of the cover.

Still another object is to provide a box of the character above set forth permitting easy assembly of the parts.

The objects of the invention thus generally set forth together with other and ancillary advantages are attained by the construction arrangement shown in the drawing and hereinafter described as preferred embodiments of the invention.

In the drawing,

Figure 1 is a perspective view of a box embodying the invention.

Fig. 2 is a similar perspective view of the box with the cover in open position,

Fig. 3 is a perspective view of the under face of the cover of the box.

Fig. 4 is a side elevational view of the box showing the cover closed and having the side connecting flange broken away to show inner details of construction.

Fig. 5 is a similar side elevational view showing the cover open.

Fig. 6 is a side elevational view of the box showing the cover in closed position and having end portions of the box broken away to show inner details of construction.

Figs. 7, 8 and 9 are enlarged fragmentary transverse vertical sectional views through one side of the box taken substantially in the planes of lines |1, 88 and 9-9, respectively, of Fig. 4.

Fig. 10 is a side elevational view of a box showing a slightly modified form of the invention and having the connecting flange on the cover shown in section to expose details of construction.

As herein shown the box comprises a relatively shallow generally rectangular body made of sheet metal and including a bottom wall 16 and a narrow peripheral edge wall including opposed parallel side walls I! and end walls l8. Upon against injury, and these beads are eifectually formed of sheet metal. In accordance with the present invention the edge wall of the body l5 and the edges of the cover l9 are curled to provide marginal beads serving to protect the user utilized in the formation of interengaging stops to limit the extent of sliding movement of the cover.

Referring now to Figs. 2 and 9, at the upper edge of the peripheral wall of the body I5 is formed a continuous head 20 made by curling the metal outwardly. Similarly the cover 19 is provided with an upstanding marginal bead 2|. At opposite side edges. of the cover, the bead 2| merges with depending guide flanges 22 shaped to engage slidably with the undersides of the body bead 20, the bead forming downwardly opening channels above and at the inner side of each of the flanged portions. The remaining portions of the cover bead 2|, that is to say all except the portions merging into the side flanges 22, have their terminal edge portions 23 (Fig. 9) bent inwardly'so as to lie substantially flush with the underside of the cover. Thus when the cover is in closed relation to the body (Figs. 1 and 4), the bead 2| thereof directly overlies the bead 20 of the body, with the inwardly bent edge portions 23 in sliding contact with the upper sides of the body head 20.

It will be observed that the cover bead 2| is in effect interrupted at its underside by the provision of the downwardly extending hook shaped guide flanges 22, and that spaced shoulders or abutments 24 are formed in the inturned edge portion 23 of the bead adjacent opposite ends of the channels along flanges 22. These shoulders or abutments are utilized to limit the endwise sliding movements of the cover relative to the body and for this purpose the body bead 20 is formed centrally of each side wall I! with an upstanding projection or rib 25 providing at opposite ends thereof shoulders 26 in opposed relation to the shoulders 24 on the cover. Thus movement of the cover slide from its normal closed position in either direction is limited by the engagement of a pair of shoulders 24 at opposite sides of the cover with a pair of shoulders 26 formed by the ribs 25. It will, of course, be

understood that the parts are suitably proportioned so that upon interengagement of the shoulders 24 and 26, the cover will be stopped in a partially open position such as shown in Figs. 2 and 5.

Any suitable means may be provided for holdin Fig. for engagement with the shoulders. 24 formed by the interruption of the cover bead.

2! as an incident to the provisions of the flanges 22.

In assembling the two parts of the box, one

end of the cover is placed upon the body with thebeads 20 and 2] in contact, and the cover is then slid onto the box with sufiicient force to override the shoulders 26 of the ribs 25, the hooked guide flanges 22 yielding sufliciently to permit such overriding movement. In the'construction shown in Fig. 10 it will similarly be necessary to force the cover to. override the bosses 28. In normal use however, the interengagement of the shoulders 24 and 26 on the cover; and body respectively, suflicientlylimit the sliding movements of the cover in either direction.

From the foregoing it will be apparent that I have provided an improved construction for boxes of the slide cover type. Thus through the provision of an upstanding bead on the cover and an underlying outwardly curled bead on the body, the usuallypresent sharp orraw metal edges are avoided. At the same time the interruption of the cover bead to form the guide flanges is utilized to provide stop shoulders engageable with easily formed cooperating shoulders on the body bead to limit the extent of opening movement of the cover. The cover bead, moreover, forms an upstanding portion readily engageable by the thumb of the hand, thereby fa'cilitating'the operation. of the cover. Finally the boxes may be readily stacked one upon the other, the bottom portion of the body being preferably made of a size such as't'o fltWithin the bead '2 I on. the cover of the next lower box in the stack.

I claim as my invention:

1. In a box of the character described, a generally rectangular body having a peripheral wall terminating at its upper edge in a continuous outturned bead, an upstanding rib formed on the bead substantially centrally of each side wall of the body, a slidable cover for said body having depending guide flanges at opposite sides shaped to extend over and around the rib and the adjacent portion of the body bead, and curled beads on the ends of said cover extending along the side edges thereof to overlie the body bead and slidably support the cover thereon, said cover beads extending substantially to the ends of the respective-flanges and forming stop shoulders disposed in the path of said upstanding ribs for engagement therewith to limit the movements of the cover' relative to the body in either of two directions.

2. A box of the character described comprising, in combination, a generally rectangular body having a peripheral wall terminating at its upper edge in a continuous outturned bead, a cover slidable longitudinally of the box body, depending guide flanges on opposite sides of the cover shaped to extend over and slidably engage the bead on the side walls of the box body to guide the cover in its movements, a bead formed at one end of the cover and having its lower side disposed substantially flush with the bottom face of the cover, said cover bead overlying and contacting the head on the box body when the cover is: closed and extending around at least one side, edge of the coverand terminating adjacent one end of the guide flange at that side, said coverbead forming a stop substantially at the juncture of the bead and the guide flange, and. an upstanding projection on the body bead positioned for engagement by said cover bead inthe movement of the cover toward open position, said end of the cover bead and said projection cooperating to define the limit positions of the cover. 7
