1 Claim.

My invention is an improvement in boxes or cartons, especially boxes or cartons made of cardboard or other sheet material that can easily be given the required form and appearance.

An important object of my invention is to provide a box or carton so constructed that the principal parts or members, such as the body and the lid or closure, can be readily shaped and completed, with a marked saving of labor and material and a corresponding decrease in the cost of production.

A fur-ther object is to provide a box or carton with a novel design of rim for either the body of the box or carton or the closure for the same.

The nature and advantages of the improvement are made clear in the following description, and the characteristics are pointed out in the claim. But the disclosure is by way of example only, and while the drawings illustrate a preferred embodiment of the invention, changes in structural details can of course be made without deviation from the general plan in which the invention resides.

On the drawings:

Figure 1 is a top plan of one of the members of a box or carton, such as the body or tray or the lid or closure therefor, both having the same construction and contour.

Figure 2 is a bottom plan thereof.

Figure 3 is a section on line 3 3 of Figure 1, of the rim, attached to the part carrying it.

Figure 4 shows the same blank shaped to be joined to the member.

Figure 5 shows the rim in front elevation before mounting it.

Figure 6. is an end view thereof; and

Figure 7 is a section on line 'I-I of Figure 3.

The box is preferably at and heart-shaped and comprises a body or tray and a closure therefor; each having the form illustrated on Figures l and 2. Both parts or members will be made by joining to a flat piece of stock I, a rim 2 with a bead 3 at the junction of the piece I and the rim. The body or tray has the same form as the lid or closure; and the two members need not be presented separately; but as will be readily understood the rim of the lid will telescope over the rim of the body when the box or carton is shut. One end of the piece I has a point 4. and the other an indentation 5. Usually the entire body and cover are made of cardboard and then completed with a glued-on paper cover or outside lining. In my invention I have found that no cardboard is needed for the rims. and this end is gained by means of stiff paper of the desired nish color, and a novel method of securing the rims in place.

The rims are fashioned out of a blank or strip of paper Ii which is adapted to be folded or doubled along a longitudinal line 1 which divides it into two portions 8 and 9, the former being the wider. Before bending, the blank is stamped to make a groove Il] along the outer edge of the portion 8. At its ends this portion has small pointed projections II along one side that will be at the outer side of the groove I Il when the groove is fully shaped. One end of the portion 8 except for the projection I I thereat is ush with the adjacent end of the portion 9; but the portion 8 has a ap I2 at the opposite end which extends beyond the adjacent end-of the portion 9 and the adjacent projection Il.

The whole of the portion 9 is covered with an adhesive upon one face.

This strip is aiiixed to the piece I by folding it along the line 'I and causing the adhesive to secure the portions 8 and 9 together; the former on the outside and the latter on the inner side of the rim. The strip is bent at the middle for the point 4 of the piece I, the periphery of which enters the groove I0. The ends of the blank come together at the indentation 5 of the heartshaped piece I opposite the point 4, and the outer side of the groove I overlaps the peripheral edges of the piece I throughout and adheres to the flat outside face thereof all along said edges. The projections I I are securely pasted down upon the piece I and may overlap one another.

On the inner face of the rim the inner portion or layer 9 is held by the adhesive against the outer portion or layer 8 and stiiens it to the necessary extent. The two ends of the portion 9 meet at the middle of the indentation 5, and the flap I2 extends past said ends and in between the portions 3 and 9 adjacent said ends. The adhesive on the portion 9 causes this ap to stick tightly to its inner surface, and thus the union of the rim 2 and the flat piece I surrounded by said rim is made permanent. The rim is stiff and strong and requires no additional fastening.

Having described my invention, what I believe to be new is:

A box member comprising a at piece of sheet material having an indentation in its periphery, and a rim for said piece, said rim having an outside layer with a groove along one edge receiving the periphery of said piece, the rim also having an inside layer folded upon the inner sur- 3 4 face of the outside layer and secured thereto; said layers having their ends adjacent the inner end REFERENCES CITED 0f the indentation, one end 0f the Outside layer The following references are of record in the being extended to overlap the opposite end of me of this patent; said inside layer, and being secured under said 5 inside layer, one side of said outside layer along UNITED STATES PATENTS the groove having triangular overlapping pro- Number Name Date jections at said indentation. 1,568,608 Klein Jan. 5, 1926 2,115,417 Di Domenico Apr. 26, 1938 LOUIS ROSENFIELD 10 2,119,360 Schleicher May 31, 1938
