8 Claims.

This invention relates to boxes or cases and particularly to improvements in the construction of small boxes or cases of the kind used as containers for small articles such as jewelry, spectacles, razors and the like.

Such boxes are usually constructed of two parts, hinged together so that one forms a body vision of more eflicient and inconspicuous means 20 for securing the leaves of a hinge to the complementary parts of a box made of molded plastic material.

To these and other ends the invention resides in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawing:

Fig. 1 is a side elevation of a box illustrating one possible application of the invention;

Fig. 2 is a similar view showing the box open;

Fig. 3 is an enlarged transverse section taken substantially on line 3-3 of Fig. 1 and lookingin the direction of the arrows at said line;

Fig. 4 is an enlarged sectional view taken subthe direction of the arrows at said line, parts being broken away to conserve space;

Fig. 5 is a view similar to Fig. 4 but illustrating the application of the cover to the hinge;

Fig. 6 is a fragmentary sectional view taken substantially on line 6-6 of Fig. 3, and looking in the direction of the arrows at said line;

Fig. 7 is a fragmentary view of the rear upper side of the body part of the box showin details of construction, and

Fig. 8 is a front elevation of the hinge detached.

Referring particularly to the'drawing in which u like reference numerals refer to the same parts in all the figures, l represents the body part, and 2 the cover part of a box or container, which .may be of usual or well known form. These parts are pivotally connected with each other, by means of a hinge generally referred to by the reference stantially on line 4-4. of Fig. 3, and looking in numeral 4. The partsof the box may be constructed of any preferred material, that illustrated being formed of moldable material, such as Bakelite" or other material having similar properties. The body I of the box maybe made 5 of any preferred size or shape and has a bead 5 extending along the upper edge of its rear wall 6. The upper inner portion of the rear wall is cut away to form the recess I intermediate the sides of the box. Communicating with this recess 10 is a recess 8 formed at the top of the rear wall and intersecting the bead 5. Intermediate the sides of the recess 1 a vertical'groove orrecess 9 is formed which communicates with the bottom of the recess 8 at its upper end. Adjacent the rear wall of the recess I, pockets or pocket-like recesses II and I2 are formed inits bottom on opposite sidesof the recess 9 and adjacent its side walls. The pocket-like recesses II and I2 are substantially rectangular in horizontal cross section, as indicated in Fig. 7 of the drawing. The rear wall of the cover 2 may be provided with corresponding recesses, except that it has no recess corresponding to the recess 8 in the rear wall of the body, and need not be described in detall.

The above described pockets and recesses provide means for securing the body and cover to a novel type of hinge whereby the cover is pivotally mounted on the body. The hinge 4 is preferably constructed of sheet metal, such as, steel, which may be somewhat resilient and comprises the leaves I3 and it which are pivotally connected with each other by any well known or preferred means. Each of the leaves has a pair of lugs or projections l5 on its free edge separated from each other to form a recess i6 between them. The free ends of the projections are bent 'up to substantially U-shape, as best shown in Fig. 5, so as to be inclined upwardly 40 and inwardly away from the plane of the body of the leaves. In the present instance a form. of hinge is illustrated in which the leaves are pivoted on apintle l1 arranged on the back of the hinge when the leaves thereof are arranged in substantially the same plane, and in which the leaves are resiliently connected with each other by means of a leaf spring iii. The spring is is provided with hooked portions at its ends adapted to engage the leaves in the recesses H5 or the recesses l9 formed therein and adapted to anchor the spring against lateral movement... The spring thus arranged serves to resiliently retain the cover'in its closed or open position.

2 I'he spring is, however, well known in the and forms no part of the present invention.

To secure the hinge to the body and cover parts of the box the bent lugs or projections on the art leaves of the hinge are pressed into the pockets or pocket-like recesses H and it which are provided therefor. By an inspection of Fig. 5, it will be noted that the lugs is project from the leaves to an extent greater than the width of the pockets and are so inclined relatively to the plane of the leaf of the spring, that pressure exerted to compress them within the pockets causes them to yield against the walls thereof as they are inserted therein, so that they become wedged or =com-.

pressed between the front and rear walls of the pockets to connect the leaf of the hinge with its .of the pockets and to bite or cut into said walls when the lugs are compressed within the pockets. When thus assembled, the pintle of the hinge is arranged in rear of the plane of its leaves and occupies a position within the recess 8 of the body part of the box. In order to further secure the hinges against liability of becoming detached I from the parts to' which they are secured, the

leaves may be made to extend laterally from the lugs l5 to provide extensions 20 arranged to engage in slots or recesses 2I formed in the rear walls of the box sections and communicating with the pockets .or pocket-like recesses II and I2 as shown in Fig.6. By this arrangement, the leaves of the hinge are anchored against shifting or pivoting relative to the box sections upon which they are secured. The recesses 9 are located behind the leaves of the hinge and serve to provide a clearance for the ends of the spring I8, which project rearwardly from the leaves of the hinge. i

It will be noted that by this construction a hinge is provided which is simple in construction,

inexpensive to make and attach to the parts of a box or other members to be hingedly connected,

and that no securing devices are required to attach the leaves of the hinge to its hinged parts which might injure or destroy the material of which the parts are constructed.

Although only one embodiment of the invention is shown and described herein, it will be understood that this application is intended to cover such changes or modifications as come within the spirit of the invention or scope of the following claims.
