Problems solved by technology

If the device is used to remove the end closures of a collapsible type package, the end closures will be removed by sawing or by a method similar to milling rather than by a method similar to shearing which, for obvious reasons, would increased dust formation

Embodiment Construction

[0043] figure 1 An example of a method for manufacturing the pack 1 of the foldable type is illustrated, which is non-limiting for the present invention. The package 1 is manufactured from an M-folded packaging roll 2 comprising two opposing side wall-shaped parts 2a, 2b and a folded bottom wall-shaped part 3 arranged between the side wall-shaped parts 2a, 2b. The packaging roll 2 is preferably produced from a deformable layered packaging material. The packaging material may comprise a core layer of polyolefin material. The core layer may further comprise a filler of mineral material, which may advantageously consist of chalk (calcium carbonate).

[0044] To form the package 1 , the two side wall-shaped parts 2 a , 2 b and the bottom wall-shaped part 3 are brought together in a tool 10 . The tool 10 connects the parts 2 a , 2 b , 3 along a connecting part 4 for delimiting the cavity 5 . The tool 10 can connect the connection part 4 eg by means of heat, pressure, ultrasound...

Abstract

The present invention relates to a device for removing an end closure (9) of a collapsible-type packaging (1), which end closure (9) closes off a channel (8) delimited by two opposing side walls (6a, 6b) of the packaging (1). The device comprises a cutting wheel (20) having circumferentially arranged, pointed teeth (21), which teeth (21) together define a circumferentially continuously extended cutting wheel cutting edge (22), which cutting wheel (20) is arranged rotatably about a first rotation axis (26), and a abutment wheel (30), which is arranged rotatably about a second rotation axis (36), which is parallel to the said first rotation axis (26), which cutting wheel (20) has a radially extended, peripheral cutting wheel face (24), which partially defines the said cutting wheel cutting edge (22), and which abutment wheel (30) has a radially extended, abutment wheel face (34), facing towards the said first cutting wheel face (24), wherein the cutting wheel face (24) of the cutting wheel (20) and the abutment wheel face (34) of the abutment wheel (30) are arranged with an overlapping contact for the formation of a cutting nip (45).

Description

technical field [0001] The invention relates to a device for removing end closures of packs of the collapsible type. Background technique [0002] The packaging of products, here primarily liquid foods such as water, milk, juice or wine, in collapsible packaging is becoming more and more common. [0003] A pack of the collapsible type refers to a pack having a cavity delimited by deformable walls, the volume of which cavity is determined by the mutual position of the walls. [0004] This type of packaging is preferably manufactured from a deformable layered packaging material. The packaging material may comprise a core layer of polyolefin material. The core layer may further comprise a filler of mineral material, which may advantageously consist of chalk (calcium carbonate). [0005] Before filling, this packaging type can exist in a flat sealed state. Thus, it is possible to sterilize the cavity of the package which comes into contact with the product and distribute the...
