Primary Examiner-Banjamin Hersh Assistant Examiner Robert R. Song Attorney-Walter Becker ABSTRACT: A shipping carton especially for large surface filter layers, which comprises a main carton section corresponding in cross section and longitudinal section to the configuration of a plurality of stacked filter layers to be shipped, said main carton section having a top and abottom wall and two sidewalls and being open at both ends which latter are closed by cap shaped end sections provided with handle means while roller means are placed on the outside of said bottom wall for facilitating the transport of said carton.

The present invention relates to a package or container for shipping large surface filter layers. Prefabricated filter layers of smaller dimensions for filter presses are stacked for dispatch and placed into a package which customarily consists of an envelope of wrapping material or of a carton.

, For large area rectangular filter layers, especially for socalled folding layers which are likewise dispatched in stacked condition, the simplepackage as referred to above is unsuitable because it permits damage to the valuable layers, especially at the corners and edges. A solid wrapping or packaging employed for this reason has the disadvantage that it is very expensive and, due to the considerable stack weight and the large dimensions of the layers, is extremely difficult to handle and to transport. 7 7

It is, therefore, an object of the present invention to provide a way of packaging large surface rectangular filter layers which will overcome the above-mentioned drawbacks.

It is another object of this invention to provide a new way of packaging large surface rectangular filter layers which will require a minimum of material while affording satisfactory protection for the layers.

Still another object of this invention consists in providing a package or dispatch container for large surface rectangular filter layers which can easily be handled and transported.

These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, in which:

FIG. 1 shows a front view of the dispatch container according to the present invention;

FIG. 2 shows a side view of the dispatch container of FIG. 1;

FIG. 3 is an isometric view of a cap for use in connection with the present invention;

FIG. 4 is an isometric view of a supporting roller for use in connection with the dispatch container of FIG. 1; and

FIG. 5 shows a detail of the dispatch container of FIG. 1. Based on the consideration that the quantity of wrapping material necessary for the stability of the wrapping'and' thereby the price for such large wrapping or dispatch con tainer may be kept particularly low if means are provided for handling and transporting the dispatch container or package and the said means are well engineered, the present invention suggests 'a'container particularly suitable as a one-way container which comprises a foldable carton adapted to receive stacked filter layers. More specifically the said folding carton has two oppositely located end faces respectively provided with caps equipped with handles and adapted to be slipped onto the carton, whereas a further end face is provided with two or more serially arranged spaced rollers which are connected to the carton by means of bands surrounding said carton in longitudinally transverse direction According to a preferred embodiment of the invention, each cap is equipped with two handles connected to the front wall of the cap, and each roller is connected to a U-shaped guiding means corresponding to the width of the end face of the carton, said guiding means being adapted to be placed upon the end face of the carton. 1

Referring now to the drawing in detail, it will be noted from FIG. 2 that a plurality of rectangular filter layers 10, for instance folding layers, for large surface filter presses of heretofore known design are assembled inva-pile or stack and are placed into a folding carton 11 conforming with the dimensions of the pile of filter layers. The carton ll encases the pile of filter layers on all sides. For purposes of protecting the corners of the carton 11 which are particularly endangered during transport and also to protect the layers 10, each of the two I oppositely located short'end faces of the carton are provided with a cap 12 which expediently consists of cardboard. The

cap 12 which is shown in greater detail in FIG. 3 is as to width and thickness dimensioned in conformity with the short carton end face and forms a hollow body. The cap 12 which is thus adapted to be slipped over the foldin carton 11, advantageously has two .handles 13. The han les 13 are spaced may consist of wood or any suitable synthetic material. is connected to a carrier member 15 preferably made of a short sheet metal member of U-shaped cross section. The carrier profile corresponds to the thickness of the carton l1 and is adapted to be placed upon a long end face thereof.

The caps 12 and rollers 14 including the carriers 15 are connected to the respective end faces of the carton by means of closure bands 16, 17 which extend in longitudinal and transverse direction of the carton for closing the same. More specifically, for the oppositely located caps 12 there are provided two longitudinal bands 16 and for each roller 14 there are provided two transverse bands 17. Advantageously, the rollers 14,15 are arranged within the area of the caps 12. For purposes of increasing the strength of the rollers and saving a vertical closure band 17, one end of a roller carrier 15 (FIG. 5) may be surrounded by the adjacent cap 12. For the nonenclosed end of the roller carrier 15 there'will then be required only one vertical closure band 17.

While as closure bands customary steel bands may be employed, it is particularly advantageous to use elastic textile ribbons 16, 17 as closure bands; which can easily be cut by scissors. In this way, the carton can beopened immediately so that the caps 12 and rollers 14 can be removed from the carton 11.

,In this manner the opening of the carton can be effected without using any tools, which are liable to damage the filter layers. 7

It is, of course, to be understood, that the present invention is, by no means, limited to the particular constructions shown in the drawings, but also comprises any modifications within the scope of th appended claims.

lclaim:

1. A shipping carton, especially for large surface foldable U shaped filter layers, which comprises: a single piece main carton section forming a tubular member corresponding in cross section and longitudinal section to the configuration of a plurality of stacked filter layers readily bendable both in flat horizontal and also upstanding vertical storage positions to be shipped edgewise therein, said main carton section having a top and a bottom wall and two sidewalls and being open at both ends, two end sections, each having an end wall and a flange around the periphery of said wall to form a cap, said end walls having handles and said caps being respectively placed over the end portions of said main carton section and closing the open ends thereof with said flanges surrounding and reenforcing the ends of said main carton section, roller means on the outside of said bottom wall and spaced from each other in the longitudinal direction of said carton, each roller means comprising a carrier member U-shaped in cross section with the bottom wall of said: main carton section mounted therein, and band means would longitudinally about said carton to secure said end sections to said main section and other band means wound transversely about said main section and the flanges of said end sections and about said carrier members to secure said carrier members to said main section and to reenforce said flanges of said end sections so that the handles and end sections can support said carton for transport.

2. A shipping carton according to claim 1, in which one end of each of said channel members is received and surrounded by the respective adjacent cap section, and in which the same band means which firmly connects said roller means to said main carton section also connects and holds the respective adjacent cap section to said main carton section simultaneously.
