Abstract

A dispenser where a container (1) is provided which container (1) contains an opening (2) at the first end and an end piece (9) at the opposite end (7) and with a container wall (5) a bag (S) is inserted into this volume in the container (1) , the bag (6) is attached to the end piece (9) , the bag (6) is provided with an opening in the first end and is attached to this open end at the opening of the container the end piece (9) is provided with a radially inward or outward directed ring-shape profile (10) , the container wall (5) is provided with a profile or circular opening (11) , which is complementary relative to the end piece ring-shaped profile (10) , the end piece (9) by elastic deformation is squeezed together with the container wall (5) in such a manner that its profile interacts with the complementary profile (11) or opening of the container wall and hence is arranged to maintain the end piece rotatable to the container wall.

Claims (18)

1. Method for manufacturing of a dispenser, the method comprising - providing a container with an opening a the first end and an end piece at the oppo-site end and with a container wall between the first and the second end, the container wall enclosing a volume, - inserting a bag into this volume in the container, - attaching the bag to the end piece, - providing the bag with an opening in the first end and attaching the bag with this open end to the opening of the container intended to extraction of material from the bag, - providing the end piece rotabably relatively to the container wall to twist the bag about its longitudinal axis by rotating the end piece in relation to the container wall, characterised in that - the end piece is provided with a radially inward or outward directed ring-shape profile, - the end piece by elastic deformation is squeezed together with the container wall in such a manner that its profile interacts with the complementary profile or opening of the container wall and hence is arranged to maintain the end piece rotatable to the con-tainer wall.
2. Method according to claim 1 characterised in that the container is provided with two complementary, inward or outward directed, ring-shaped profiles in continuation of each other in the container wall and that a closing bottom in continuation of the profiles is provided and that the end piece is released from the rest of the container such that the container is provided with a container wall with one of the profiles and an end piece is provided with the bottom and the other complementary profile, where the end piece by elastic deformation is pressed together with the complementary pro-file of the container wall and is arranged to rotatably maintain the end piece to the container wall.
3. Method according to claim 2 characterised in that the end piece is released from the rest of the container wall by cutting, while the bag is out stretched in the container to give great distance to the container wall during cutting.
4. Method according to claim 1 or 2 characterised in that a smaller friction coeffi-cient is provided between the bag and the inner wall of the container at the end piece than at a distance from the end piece.
5. Method according to any of the previous claims characterised in that air is blown into the bag to press the bag against the container's inner wall before the bag opening is attached to the container opening.
6. Method according to any of the previous claims characterised in that the bag is provided with a diameter which roughly corresponds to the diameter of the container opening and the bag is inserted into the container, whereupon the bag in the container is heated up and gas is blown into the bag to expand the bag against the container in-ner wall under heat.
7. Method according to any of the previous claims characterised in that the container is provided with a plastic moulding.
8. Method according to claim 1 or 2 characterised in that the bag is attached to the container's first end over an extension which is larger than the extension of the at-tachment at the end piece.
9. Method according to claims 1, 2, 3, 4 or 8 characterised in that the bag is inserted after manufacturing of the container.
10. Dispenser for viscous materials, where the dispenser comprises a container com-prising a bag of flexible material, where the bag has an opening in one end, which is attached to an opening in the container for extraction of the material from the bag, where the container has an end piece in the opposite end and an enclosing container wall between the two ends, where the end piece is rotatable in relation to the container wall and where the other end of the bag is attached to the end piece with fastening means such that the bag, when the end pieces are rotated in relation to the container wall, is twisted about its longitudinal axis characterised in that the end piece has a radially inward or outward directed, ring-shaped profile and that the container wall has a profile or a ring-shaped opening, which is complementary in relation to the ring-shaped profile of the end piece and that the profile of the end piece interacts with the container wall complementary profile or opening and is arranged to maintain the end piece rotatable to the container wall.
11. Dispenser according to claim 10 characterised in that the dispenser in a pre-active state comprises a container wall having two radially inward or outward directed, ring-shaped profiles in continuation of each other and a bottom in continuation of the pro-files and where the container in an active state has an end piece with a ring-shaped profile and a container wall with a complementary ring-shaped profile, where the end piece profile interacts with the container wall profile to maintain the end piece ro-tatable to the container wall.
12. Dispenser according to claim 10 or 11 characterised in that the bag is attached to the container's first end over an extension larger that the extension of the attachment at the end piece.
13. Dispenser according to claim 10 or 11 characterised in that the dispenser is pro-vided with a friction coefficient, which is smaller between the container inner wall at the end piece in a distance from the end piece.
14. Dispenser according to claim 13 characterised in that the bag material in one end is arranged to have a cross section, which under atmospheric pressure is at least as large as the inner cross section of the container such that the bag when filled up can abut against the inner side of the container.
15. Dispenser according to claim 14 characterised in that the bag material is arranged to comprise a volume under atmospheric pressure, which volume is equal to or larger than the inside volume of the container.
16. Dispenser according to claim 15 characterised in that the fastening means are arranged to maintain the bag over an extension less than the extension of the bag at its upper attachment around the container opening.
17. Dispenser according to any of the claims characterised in that the dispenser has an oval-shaped cross section.
18. Dispenser according to claim 17 characterised in that the container wall has re-cesses with a bead/profile enclosing an end piece inside the bead/profile and interacts with a corresponding bead/profile.
