4 Claims.

This invention relates to new and useful improvements in container bodies and methods of making the same and more particularly to corrugated containers such as boxes, cartons and the like having a plurality of wall thicknesses.

The principal object of the present invention is to provide a novel container body of the character set forth having a plurality of wall thicknesses constructed and arranged to provide an offset shoulder construction for the reception and seating of a cover or closure member.

Another object of the present invention is to provide a novel method for making containers of the character set forth wherein machining or otherwise cutting away a portion of one wall section to produce an offset shoulder construction is entirely eliminated.

A further object of the invention is to provide a novel method for making containers of the stated character having an off-set shoulder construction adjacent one or both ends of said containers either internally or externally thereof.

A still further object of the present invention is to provide a novel method for making con- 5 tainers of the character stated which renders manufacture of the same comparatively simple and inexpensive.

Other objects of the invention and the features and details of construction thereof are set forth hereinafter and shown in the accompanying drawings, in which:

Referring now to the drawings, the invention contemplates in general the formation of a continuous composite run of board having a plus rality of corrugated wall thicknesses wherein one wall thickness is of less width than other wall thicknesses thereof, as for example, in the manner shown in Fig. 1 of the drawings wherein a continuous run of single-faced transversely corrugated board A is fed by means of a roll 'I into parallel contact with the adjacent liner or facing of a continuous run of double-faced transversely corrugated board B passing intermediate said roll I and another roll 2 disposed in opposition thereto. The single-faced run A is fed into contact with the double-faced run B so that the exposed ridges of the corrugations of the former contact the facing or liner of the latter, said runs A and B being secured together to form a continuous. composite double-walled run C by means of adhesive previously applied to the ridges of said corrugations of the run A from a paste box 3 by rolls 4. The composite run C passes intermediate a series of rolls 5 and steam plates or other suitable heating elements 6 where the same is dried and thereafter passes intermediate rolls 1 and 8, one of which is provided with an adjustable cut-off element 9 operable to sever sections or blanks D from said composite run C at predetermined intervals transversely thereof.

While the foregoing description and illustration relates particularly to the manufacture of container blanks having a plurality of corrugated wall thicknesses wherein the axes of the corrugations of each are substantially parallel, said invention is equally adaptable to the manufacture of container blanks having a plurality of corrugated wall thicknesses wherein the axes of the corrugations of each are disposed substantially at right-angles to the axes of the corrugations of adjacent wall thicknesses in accordance with any one of the several methods of making corrugated board disclosed in U. S. Letters Patent No.

2,008,974 dated July 23, 1935, as well as my copending application for U. S. Letters Patent bearing Serial No. 46,171, filed October 22, 1935 and the co-pending application for U. S. Letters Patent of David Weber bearing Serial No. 46,389, filed October 23, 1935.

' One such method of making corrugated board of the above character is diagrammatically shown 7 inpart in Fig. 8 of the drawings hereof, wherein pre-formed single-faced sheets of corrugated board B are successively fed in abutting relation by continuously moving dogs l into parallel contact with a continuously fed independent run of liner or facing sheet II. The facing sheet I l is fed so that the same contacts the exposed ridges of the corrugations of said pre-formed sheets 3' and is secured thereto to form a substantially continuous double-faced run E by means of adhesive previously applied to said corrugations from a paste box I2 by rolls l3. In this ramification of the invention the axes of the corrugations of the pro-formed sheets B extend in the direction of feed thereof and substantially at rightangles to the axes of the corrugations of the continuous run of single-faced transversely corrugated board A which is fed by a roll l4 into parallel contact with the liner or facing I I of the previously described composite double-faced run E passing intermediate said roll 14 and a roll l disposed in opposition thereto. As shown the exposed ridges of the corrugations of the singlefaced run A contact the facing or liner l l of the run E and the same is secured thereto by means of adhesive previously applied to said corrugations from the paste box 3 by rolls 4 to form a continuous composite double-walled run C, the axes of the corrugations of adjacent wall thicknesses of which are disposed substantially at right-angles to each other.

The composite run C then passes intermediate the rolls 5 and steam plates or other suitable heating elements 6, where the same is dried and there after passes intermediate the rolls 1 and 8, one of which carries the adjustable cut-off element 9 operable to cut sections or blanks Dv from said composite run C at predetermined intervals transversely thereof.

In the foregoing descriptions, it is to be particularly observed that in each instance one particular wall thickness is of greater width than others so that the latter project a predetermined distance beyond at least one side edge of the former as shown, and therefore the container blanks D and D severed from the composite runs C and C respectively will likewise comprise a plurality of wall thicknesses wherein one of said thicknesses is of less width than others as disclosed in Figs. 2 and 9 of the drawings. However, it is pointed out that the invention may be practiced with equal effectiveness by reversing the relative dimensions of said wall thicknesses so that the present narrower wall thickness is of greater width than others.- Furthermore, in certain instances it may be desirable to form container blanks wherein one wall thickness projects beyond two opposite side edges of the other wall thicknesses thereof as shown in Figs. 5 and 12 of the drawings, and container blanks of this particular character, designated generally as F and F respectively, may be formed in the manner disclosed in Figs. 1 and 8 by forming wall thicknesses having predetermined relative widths and positioning the same transversely with respect to in Figs. 2 and 5 thereof.

After the container blanks have been severed from the composite runs in the manner previously described, the same are scored transversely thereof parallel to their end edges H5 at predetermined spaced intervals depending upon whether a container having a corner or side wall seam is desired, and, for example, in the former instance the blanks are scored transversely at equally spaced intervals with respect to each other and the transverse end edges l6 thereof as indicated at I! in Figs. 2 and 9 of the drawings so that the line of abutment of said end edges will reside at a corner of a container, and in the latter instance the blanks are similarly scored transversely at predetermined spaced intervals as indicated at I 8 in Figs. 5 and 12 so that the line of abutment of the opposite end edges IE will reside in a side wall portion of a container body.

The container bodies are formed by bending the blanks previously described along their several transverse scores I! and I8 respectively, to place the opposite end edges l6 of each in substantially abutting relation as shown in Figs. 3, 6, 10, and 13 of the drawings, said end edges being secured in the aforementioned abutting re lation by any suitable means such as an adhesive strip or the like IS. The container bodies may be formed so that the narrower wall thicknesses are disposed externally or internally of the wall thicknesses of greater width as may be desired, and in the former instance disposition of said narrower wall thickness externally of the other wall thicknesses, produces a shoulder 20 on the exterior of said container body which terminates at its inner edges in a projecting sleeve portion 2| formed by the inner wall thickness. Similarly, formation of a container body with the narrower wall thickness disposed internally of the other produces a shoulder 22 in the interior of said container body which terminates at its outer edges in a projecting sleeve portion 23 formed by the outer wall thickness.

In the present instance the projecting sleeve portions 2| of the container bodies shown in Figs. 3 and of the drawings are arranged to receive closure members 24 which overlie the same in abutting relation with respect to the external shoulders thereon, and the projecting sleeve portion 23 of container bodies illustrated in Figs. 6 and 13 are arranged to receive similar closure members 25 which are inserted inwardly of said sleeve portions 23 in the manner shown in either Figs. 7 or 14 in abutting relation with respect to the internal shoulders 22.

While the invention has been illustrated and described in connection with corrugated or like container bodies of tubular form and open at the ends, it will be obvious that the novel shoulder and projecting sleeve construction herein disclosed and forming the subject of the present invention may be embodied in the manufacture of still other types of containers or container bodies whether of the tubular, open-ended form shown, or provided with integral inclosure flaps at one end thereof, of the general character disclosed in my co-pending application for Letters Patent of the United States bearing Serial No.
