8 Claims.

This invention relates to the fabrication of boxes, especially to boxes made of pasteboard or like material, and more particularly to such boxes having a heart-shaped or other curvilinear or irregular contour.

In the fabrication of such boxes, according to conventional methods, difficulty is experienced in performing by machinery a substantial part of the steps involved, for the reason that the edge joint between the bottom wall and side wall of the container element of the box structure, and similarly the edge joint between the top wall and side wall of the cover element of the box structure, has to be made with varying degrees of curvature, and, in the instance of heart-shaped boxes, must include a V-shaped point which constitutes an abrupt departure from curvilinear form, while the V-shaped notch at the apex between the upper lobes of the heart-shape, constitutes a somewhat different departure, involving even greater difficulties in fabrication.

One of the conventional structural components creasing along the sides of the box adjacent to its point and decreasing along the sharper curves opposite the point.

The application of such a strip in use involves certain difiiculties, among which may be mentioned the need for providing means guiding the proper positioning of the strip about the bottom wall to prevent the strip from being placed in a position in which any one of the tongues crosses the sharp corner formed by the notch at the incurved apex region at the top of the heart.

More than ordinary skill is also required in combining the notched strip with its associated parts in the fabrication of the box by the aforesaid method.

Under such conditions it is the general object of the present invention to provide a novel method of fabricating such boxes which makes it possible to press up in a single operation a base member for the container element, or a top member for the cover element, as the case may be,

which not only is of the desired curvilinear contour, with intervening irregular breaks in the curvature, such as the point and the notched apex of the heart, for a heart-shaped box, but which also includes, as an integral part of its 5 structure, an upright wall portion adapted to serve as a component of the side wall of the container element, or as a component of the side wall of the cover element, respectively.

A further object is to provide such a combined bottom member and side component, and likewise such a combined cover member and side component that, in each instance, the other side components of the member can be applied in the form of suitable lengths of stock strip material, such as pasteboard, or any other suitable strength-giving material, such as a strip having a glossy or a matte surface, of any desired color, the work being done by operatives of no greater than average skill or training, and certain steps being performable by the use of suitable mechanism, with incidental economy in fabrication.

As a summary of the above objects, it is the outstanding object of the invention to provide, in a method of fabricating boxes of the class described, the step of die-pressing a blank of sheet material to form around its periphery an upright flange of given height and having folds therein at suitable intervals to compensate for the presence of excess material in the flange, the step of attaching to the side wall component so formed a band adapted to serve as an extension side wall component of sufficiently greater height to surround completely the exterior side of the firstnamed component, and to extend above the same to the desired height of the complete wall, and the step of attaching to said band a strip of finish material, folded over the free edge or rim of the band and covering completely the outer side thereof, and extending down within the side wall to, and over, the region of the inner peripheral joint.

Other objects and features of the invention will be pointed out as the description of the particular physical embodiment selected to illustrate the invention proceeds.

In the accompanying drawings, like characters of reference have been applied to corresponding parts throughout the several views making up the drawings, in which: 50

Fig. 6 shows a completed component, capable of being used either for a container component or a cover component, according to its size;

Fig. 7 isa view in transverse, vertical section, on an enlarged scale, of a box composed of a container component and a cover component, of appropriate size, respectively, to fit together telescopically and each embodying the structure illustrated in the preceding figures, fabricated according to the method of the present disclosure; this view illustrating also in dotted lines masks of desired form and contour, applied to the foundation box structure.

In a now-preferred embodiment of the invention selected for illustration and description, the part designated by the reference character I! is a blank of sheet material, such as pasteboard, die-cut to the shape of a heart, which is the illustrative example of a contour intended to be fabricated in the present instance. This blank may, or may not, have a score line l2 to facilitate the next step, viz. that of bending up the edge, in pursuanceof the invention, which step may be performed with suitable dies, in a die press (not shown).

Fig. 2 shows the blank of Fig. 1 after having been pressed to form an upright flange I3, of less height preferably than that which the side wall of the completed box is intended to have, this flange constituting a structural element of the side wall. Its material is fold-ed at intervals, by the pressing operation, as indicated at It, so that the compensation for the transition from the flat state of the blank to the curvilinear wall shape is effected by thus infolding and compressing the marginal material of the blank in the area defined by the edge'lfi thereof and the crease line l2, whether the latter be actually scored, or imaginary.

This step is performed by machinery on the main structural component of the box and produces a wall element l1 conjoined integrally with the base II in the strongest possible manner, in contradistinction to the method of cutting specially shaped and spaced notches into a flange forming part of a wall strip which is thereafter adhered to the bottom of the box in an operation requiring unusual skill, training and dexterity, as has been already noted briefly, in the opening paragraphs of the present specification.

According to the present method, the next step consists in assembling with the side wall flange If a structural wall element 58 comprising, as illustrated in Fig. 3, a strip of suitable material, such as pasteboard, of uniform continuity and width from end to end, its width being preferably that of the intended height of the side wall in the completed box component, whether the same is to be used for the container component or the cover component.

The strip I8 is preferably gummed entirely over the face l9 that is to be applied around the exterior circumference 20 of the component H, to facilitate adhering the strip to the flange ll,

It will be noted that, in the original blank I i,

as shown in Fig. 1, the edge of the blank is formed with a notch 24 at the point, and with a slit 25 at the apex, the first being designed to facilitate an accurate meeting of the various uprights edges at the point region 2!, and the notch 25 being designed to facilitate the formation of a neat clearly defined upright line 26 at the apex of the heart (see Figs. 4, 6, and 7).

The main structural elements of the box component having thus been assembled, as shown best in Fig. 4, the next step in fabrication of the component is to apply thereto a finish strip 21, which may desirably be made of enamelled paper, having its entire surface gummed on the side 28, which is to be contiguous to the edge l3 and adjoining faces ll and El of the flange, the strip being of sufficient extent to cover the entire outer face I! of the side wall and at least that portion of the inner wall which includes the inner peripheral joint 3!! between the flange and the band.

After the finish strip has been applied, the component presents the. appearance shown in Fig. 6, and constitutes a complete structural entity, whether it is to be used as a container,

or as a cover element of the box.

It may be further reinforced, or supplemented, by securing thereto, as by pasting, a mask, as
