Claims. 1

This invention relates to containers and methods for manufacturing same, and more particularly to containers made from sheet material having one or more apertured or perforated walls and methods for their manufacture. The invention has for an object the provision of improved containers of this character. This appli cation is a division of application Serial No. 576,971, filed February 3, 1945, now Patent No.

form upstanding side wall portions, the unslit marginal portions It being simultaneously bent downwardly out of the plane of the blank. Extending outwardly from the central portion of the blank H3 in which the tongues it are formed is a pair of side wall forming members I8 which may be bent upwardly along the fold lines 20. In order to complete the carton a pair of edgeforming strips 22 (Fig. 4) is provided which may be adhesively secured to the upper ends of the side members or tongues l 6, the opposite ends of the strips 22 being turned inwardly for securement to the end side wall members It. The downwardly extending marginal portions 14, shown in Fig. 2, are bent inwardly and secured, preferably by an adhesive, to the undersurfaces of the portions of the blank IEI which form the perforate bottom wall of the container or carton. as shown in Fig. 1. In this embodiment of the invention the free ends of the tongues 16 are spaced apart when formed so as to leave a central longitudinally extending portion 24 which extends throughout the length of the bottom wall of the container. It will of course be understood that any suitable top or closure member may be provided for cooperation with the finished container shown in Fig. l, and the top or closure member may be secured to the body of the container in any desired manner. The central portion 24 and the bent marginal portions H! serve as reinforcements for the bottom wall and the container. In the event that the container is formed of sheet metal the marginal portion M may be secured to the bottom wall by welding or soldering and the strips 22 may likewise be secured to the tongues I6 and the end side wall members l8 by soldering or welding.

In the embodiment of the invention shown in Figs. 5 and 6, the central portion of a suitable i blank 26 is again provided with rows of U-shaped slits 28, the slits in this case overlapping and having a portion of one leg of each slit coinciding with the adjacent slit to provide pairs of sideby-side tongues 30. In the embodiment shown the free end of each tongue terminates short of the base of the adjacent tongue so that a space 32 is left adjacent the free end of each tongue. If it is desired to form higher side walls on the container, however, the tongues may extend entirely to the base of the adjacent tongue so that the height of the side walls formed by the tongues will be the same as the width of the bottom wall of the container. In this embodiment of the invention the tongues are bent upwardly from the plane of the blank, as in the previously described embodiment, to form spacedapart members, but the unslit marginal portions 34, which extend along the opposed longitudinal edges of the blank, are not bent downwardly but instead are bent upwardly and secured into face-to-face engagement with the side members 30 constituting the side walls, as shown best in Fig. 6.

Adjacent the opposite ends thereof the blank 26 includes extending side wall forming portions 36 which may be bent upwardly about the fold lines 33 to form the end walls of the carton or container. These portions 36 are preferably of greater height than the tongues 30 and are suitably scored, as indicated by the score lines ML so that the portions 42 beyond the score lines may be bent downwardly as shown in Fig. 6. Suitable edge-forming strips 54, similar to the strips 22 shown in Fig. 4, are provided for securement to the upper ends of the tongues 30 and the inwardly turned ends of these strips 44 extend under the downwardly turned portions 42 of the end walls 36. As shown, the longitudinal marginal portions 34 are so formed as to extend beyond the fold lines 33 which correspond to the ends of the bottom wall of the container, and these extending portions are bent inwardly into engagement with and are preferably adhesively secured to the outer surfaces of the end walls 36, as shown in Fig. 6.

In Figs. '7 and 8 the invention is shown as embodied in a carton of the type having openable and closable end flaps. The various parts of this carton which are similar to the corresponding parts of the carton shown in Figs. 1 to 4 have been given similar reference numerals. Thus it will be observed that the carton consists of side members or tongues lfia. which are formed from the material of another wall Illa, in this case a side wall but in the embodiment of Fig. 1 the bottom wall, this wall its having a longitudinally extending central strip 24a and the marginal portions Ma being inturned into face-to-face engagement with the outer surfaces of the wall lilo intermediate the apertures left by the tongues [6a. In place of the edge-forming strips 22 shown in Fig. 4, the carton is provided with a solid wall-forming portion 45 which is provided along opposed edges thereof with edge-forming strips 48 adapted to be adhesively secured to the free ends of the tongues Ilia. The end wall portions [8a in this embodiment of the invention are provided with tuck flaps 50, as shown, which, when the ends of the carton are closed, extend within the side walls formed by the portion 46 and the side members or tongues ilia, and these ends of the carton may be opened or closed at will to fill the carton or remove the contents thereof. If desired, one of the end walls may be adhesively secured in its closed position so that the carton may be opened from one end only Without destroying the carton.

It will now be apparent that the process of this invention may be employed for the manufacture of various types of cartons, containers, trays. dishes and the like, and that attractive and rugged articles are produced with a minimum number of manipulative steps and with the employment of a minimum amount of material relative to the size of the finished article. Various types of foldable or formable material may likewise be employed depending upon the use to which the finished article is to be put, and various types of finishes, such as plating or enameling, may be employed. The process may be carried out by cutting or stamping the blank of sheet material into the desired configuration, slitting the formed blank, striking or bending upwardly the end walls and the several tongue members forming the side walls, bending the lower marginal portions of the bottom wall and securing them in face-to-face relationship with a side or bottom wall of the container, and securing the upper ends of the tongue members to an upper edge portion 22 or 44 as in Figs. 1 to 6 or to a separate top wall member 45 as in Figs. '7 and 8.

Claims broadly directed to the process of forum ing containers of the general type herein disclosed are contained in my co-pending applica tion Serial No. 96,719, filed June 2, 1949, now abandoned, as a division of my previously referred to application, Serial No. 576,071, now Patent No. 2,476,948.

While I have shown particular embodiments of my invention, it will be understood, of course,

that I do not wish to be limited thereto since many modifications may be made, and I, therefore, contemplate by the appended claims to cover any such modifications as fall within the true spirit and scope of my invention.
