Sheet-material container for a dispensing unit and method for producing a sheet-material container
A dispensing unit includes a first sheet-material bag which is filled with a first composition, a second sheet-material bag which is filled with a second composition, and a head part disposed on a first end of the first sheet-material bag and a second end of the second sheet-material bag. The head part has a first outlet channel for the first composition and a second outlet channel for the second composition, the first and second sheet-material bags are open on the first and second ends, and the first and second outlet channels are filled with the first and second compositions, respectively. A closure part is configured to couple with the head part, where the closure part is openable or removable by a user.
1. A dispensing unit, comprising:
a first sheet-material bag which is filled with a first composition;
a second sheet-material bag which is filled with a second composition;
a head part disposed on a first end of the first sheet-material bag and a second end of the second sheet-material bag, wherein the head part has a first outlet channel for the first composition and a second outlet channel for the second composition, wherein the first and second sheet-material bags are open on the first and second ends and wherein the first and second outlet channels are filled with the first and second compositions of the first and second sheet-material bags, respectively, prior to an initial use of the first and second sheet-material bags in the dispensing unit; and
a closure part configured to couple with the head part, wherein the closure part is openable or removable by a user.
2. The dispensing unit according to claim 1 , wherein the first and second compositions flow from the first and second sheet-material bags and into the first and second outlet channels, respectively.
3. The dispensing unit according to claim 1 , wherein the first and second compositions are thermoplastic or elastomer.
4. The dispensing unit according to claim 1 , wherein at least a portion of the first and second compositions contact the closure part.
5. The dispensing unit according to claim 1 , wherein an end that is opposite the second end of the second sheet-material bag is closed with a clip or a glue or a weld.
6. The dispensing unit according to claim 1 , wherein the removable closure part is an attachable or screw-on cap.
7. The dispensing unit according to claim 1 , wherein the head part has a first piercing unit and wherein the first sheet-material bag is pierced when the head part is disposed on the first end of the first sheet-material bag.
8. The dispensing unit according to claim 1 , wherein the first outlet channel is separate from the second outlet channel within the head part.
9. The dispensing unit according to claim 1 , wherein the first composition is different from the second composition.
10. The dispensing unit according to claim 1 , wherein the first and the second sheet-material bags are disposed parallel to each other.
11. The dispensing unit according to claim 1 , wherein a first length of the first sheet-material bag and a second length of the second sheet-material bag are a same length.
12. The dispensing unit according to claim 1 , wherein a first diameter of the first sheet-material bag is different than a second diameter of the second sheet-material bag.
13. The dispensing unit according to claim 12 , wherein a difference between the first diameter and the second diameter is proportional to a mixing ratio of the first composition to the second composition.
14. The dispensing unit according to claim 7 , wherein the first piercing unit has a first opening tube which forms a part of the first outlet channel and has a slanted shape and/or sharp edges.
15. The dispensing unit according to claim 7 , wherein the head part has a second piercing unit and wherein the second sheet-material bag is pierced when the head part is disposed on the second end of the second sheet-material bag.
16. The dispensing unit according to claim 15 , wherein the second piercing unit has a second opening tube which forms a part of the second outlet channel and has a slanted shape and/or sharp edges.
17. A method for producing a dispensing unit of claim 1 , comprising the steps of:
applying the head part to the first and second ends of the first and second sheet-material bags;
opening the first and second sheet-material bags; and
closing the first and second outlet channels;
wherein the steps of opening the first and second sheet-material bags and closing the first and second outlet channels occur prior to an initial use of the first and second sheet-material bags in the dispensing unit and wherein the first and second outlet channels are filled with the first and second compositions of the first and second sheet-material bags, respectively, prior to the initial use of the first and second sheet-material bags in the dispensing unit.
18. The method according to claim 17 , wherein the step of opening the first and second sheet-material bags occurs automatically by a piercing unit on the head part when the head part is applied.
