Snventor Gttorneg Patented Feb. l1, 1947 and? PAPER BOX CGNSTRUCTEN Sterling R. Arner, Charlotte, N. C., assignor to Old Dominion Box Company, Lynchburg, Va., a corporation of Virginia 1 Claim. (Cl. 229--5.5)

This invention relates to a paper container and more especially to a cylindrical container such as used for packaging half-pound and one pound quantities of tobacco, although it is to be clearly understood that this type of container can be used for any other purpose desired.

It is an object of this invention to provide a container having a hermetically sealed reinforced bottom and one which presents a very neat appearance.

This is a divisional application forming a part of original application, Serial Number 495,288, led July 19, 1943, Patent No, 2,356,194, Aug. 22, 1944.

It is another object of this invention to provide a container having the wrapper folded over both the upper and lower edges thereof and ein bedded between the inner and outer layers of the walls of the container and the upper and lower end thereof.

It is another object of this invention to provide a container having a bottom whose outer edge is flush with the inner wall of the shell of the container with a sheet covering the bottom and the lower edges of the inner shell of the container and being turned upwardly and embedded between the inner and outer shells of the container, the outer shell of the container having a covering whose upper and lower edges are tur-ned inwardly and are embedded between the outer and inner shells of the container.

It is another object of this invention to provide a container having a reinforced bottom member View of the lower portion of Figure 3 before the parts are compressed together;

Figure 5 is a cross-sectional View taken along the line 5-5 in Figure 1;

Figure 6 is an elevational view of one side of the bottom member. v

Referring more specically to the drawings, the numeral lo indicates the inside side wall of the box which projects above the outer side wall li, and a suitable cover is adapted to fit over the upper portion of the inside side wall Hi, and have its lower edge nt snugly against the upper edge of the outside wall ll. The outside side wall l l is covered with a suitable wrapper l2 on which the trade-mark or other suitable printed matter is placed. The wrapper l2 is turned inwardly between the inner and outer side walls at the upper and lower ends as indicated by the upturned portion I3 in Figure 2. The top edge of the wrapper is likewise turned inwardly and downwardly between the inner sidewall E6 and the outer side wall i l inner side wall lll is a bottom member lli which is secured in position by means of a bottomlabel l5 which has its edges turned upwardly and secured by any suitable means such as an adhesive between the inner and outer side walls as at It. This bottom retaining label l5 is usually composed of what is termed as white face kraft paper, so as to give the proper strength for retaining the bottom lll in position.

In Figures 3 and 4, the same reference characters apply as have previously been used in dewith a label covering the bottom member and embedded in the lower side walls of the container, with a reinforced bottom member disposed within the container, the reinforced bottom member being glued to the initial bottom member by a special type of pattern gluing which prevents uneven expansion of the bottom members and also which gives more perfect gluing of the additional bottom member to the regular bottom member.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which:

Figure 1 is an elevational view of the container with the bottom portion thereof bro-ken away;

Figure 2 is an enlarged vertical sectional View of the lower portion of the structure shown in Figure 1 before the parts are compressed together;

Figure 3 is a view similar to Figure 1, but showing an additional bottom member disposed within the container;

Figure 4 is an enlarged detail vertical sectional scribing Figures 1 and 2, and in Figure 4, there is an extra bottom member ll fitted within the box, as it is noted that in Figures 3 and 4 this extra bottom member is disposed immediately above the original bottom member. This extra bottom member rests on the inside top surface of the regular bottom Hi. This extra bottom l'l is secured in position by having a flush t at its edges against the inner wall of the inner side wall IE! and it also has suitable adhesive such as glue placed on its side which'is disposed next to the regular bottom Ill.

The pattern gluing used on the surfaces between the members I4 and IT may be of any desired formation, but I have found that by using the pattern gluing as shown in Figure 6 that l obtain a very finished product without uneven expansion of the two bottom members of the box, and when an extra bottom is used, the two bottoms are more securely and permanently adhesively bound together when pattern gluing is employed. This pattern gluing is especially Fitting snugly within the adaptable in a structure of this type as it prevents undue expansion, due to moisture, in one direction more than another, and provides uniform expansion on account of moisture and therefore prevents buckling and wrinkling. I have found that concentric and radially disposed pattern gluing is very desirable in the manufacture of boxes of this type. In the form shown, I provide a plurality of concentric rings 25 and 26 of adhesive such as glue, and a plurality of radially disposed strips of adhesive 21 extending between the two concentric rings 25 and 25. When the disk is moistened, and adhesively secured to another member in face to face relation, this type of pattern gluing results in even application, and prevents ay wrinkling whatsoever.

In Figures 2 and 4, the bottom structure of the box is shown on an enlarged scale with the inner and outer walls separated, that is before the parts of the box are placed in a suitable press and the parts compressed together, while in Figures 1 and 3 the parts are shown in a position before compression takes place.

In assembling the box as shown in Figures 1 to 4 inclusive, the inside wall I0 has the bottom Ill inserted therein and the sheet of material I5 is then applied by overall gluing, thus the periphery IS projects straight outwardly. This periphery also has glue on both surfaces thereof which are adapted to contact the outer periphery of the inside wall III, and the inner periphery of the outside wall II. The outer wall II has previously been formed by applying the covering portion I2 by means of suitable adhesive and with the upper and lower edges of the covering portion I2 turned inwardly and downwardly and upwardly as the case may be as indicated at I3. Suit- EEO able adhesive is applied to the interior surface of I wall II, and then wall II is slid upwardly in Figure 2 over the wall IG, and this tucks the extension I6 tightly against the outer surface of wall Iii, and although in the drawings there is shown a space between walls IG and II it is really a very tight t, and therefore, the adhesive on the inner surface of the wall II causes walls i6 and H to be tightly bound together, and of course somewhat greater pressure is present at the lower ends of the walls III and II which rmly causes 4 the folded portions I3 and I4 to be tightly secured together by adhesive which is present on a"- count of the fact that adhesive has been wiped oli the inner surface of the wall II as it passes by folded portion I6.

In the drawings and specication, there has been set forth a preferred embodiment of the invention, and although specic terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being defined in the claim.

I claim:

A circular paper box having inner and outer sidewalls secured to each other, a circular bottom tting snugly within the lower end of the inner side wall, a sheet of paper adhesively secured to the lower surface of the bottom member, and having its outer edge folded up and secured between the inner and outer side walls of the container, the outer side wall having a cover whose upper edge is tucked down between the inner and outer side walls, and whose lower edge is turned upwardly and secured between the inner and outer side walls, and an additional bottom member disposed within the inner side wall, and adhesively secured to the first-mentioned bottom, and having its periphery tting tightly against the inside surface of the inner side walls, the adhesive on the additional bottom member being in the form oi a plurality of concentric rings with radially disposed strips of adhesive extending between the rings.
