Device for holding and vacuum-sealing a container having an opening
View Patent ↗A device for holding and vacuum-sealing a container as used in particular in the internal and/or external coating of containers. The device holds and vacuum-seals at least one container and has a sealing device for sealing the pouring opening in a defined end state also to comprise a holder with an introduction region, into which the wall region, which adjoins the pouring opening, together with the pouring opening, can be at least partially introduced, and a cage, which interacts with the holder and holds at least one clamping element in such a manner that, when force is applied to the cage in the direction in which the container is introduced into the defined end state, the clamping element can be guided out of a position in which it substantially releases the introduction region into a position in which it projects into the introduction region.
1. A device for holding and vacuum-sealing at least one container ( 3 ) having an opening, comprising
a sealing device ( 6 ) for sealing the opening in a defined end state, which device comprises
a holder with an introduction region ( 2 ), into which a wall region ( 3 a ), which adjoins the opening of the container ( 3 ) is at least partially introduced, and
a cage ( 9 , 10 , 11 ), which interacts with the holder and holds at least one clamping element ( 8 ) in such a manner that, when force is applied to the cage ( 9 , 10 , 11 ) in the direction in which the container ( 3 ) is introduced into the defined end state, the clamping element ( 8 ) can be guided out of a position in which it substantially releases the introduction region ( 2 ) into a position in which it projects into the introduction region ( 2 ).
2. The device as claimed in claim 1 , which holds and vacuum-seals at least one container ( 3 ) with a wall region ( 3 a ) which adjoins the opening and is in the form of a neck.
3. The device as claimed in claim 1 , wherein the cage ( 9 , 10 , 11 ) also comprises a carriage ( 9 ) which is displaced along the direction of introduction and a guide surface ( 11 ) arranged in a fixed position, between which the at least one clamping element ( 8 ) is held.
4. The device as claimed in claim 1 , wherein the at least one clamping element comprises a ball ( 8 ).
5. The device as claimed in claim 1 , wherein, the cage ( 9 , 10 , 11 ) holds a multiplicity of clamping elements ( 8 ) which are spaced apart from one another and are introduced into the introduction region ( 2 ) in a direction which is transverse with respect to the direction of introduction.
6. The device as claimed in claim 1 , wherein, the cage ( 9 , 10 , 11 ), in order to guide the at least one clamping element ( 8 ), has a guide surface ( 11 ) which is part of a holding body ( 1 ) which delimits the introduction region ( 2 ).
7. The device as claimed in claim 6 , wherein the guide surface comprises a holding ring or holding cylinder.
8. The device as claimed in claim 1 , wherein the cage ( 9 , 10 , 11 ), in order to guide the at least one clamping element ( 8 ), has a guide surface ( 11 ) which effects a narrowing of the introduction region ( 2 ) in the direction of introduction.
9. The device as claimed in claim 1 , wherein the cage ( 9 , 10 , 11 ) and/or the clamping element is designed in such a manner that the clamping element ( 8 ) is latched into grooves and/or projections ( 14 a , 14 b ) formed on the neck ( 3 a ) of the container ( 3 ), which is to be introduced.
10. The device as claimed in claim 1 , wherein the introduction region ( 2 ) is designed to hold a vacuum system, which can be introduced from the rear side with respect to the direction of introduction.
11. The device as claimed in claim 1 , which also comprises a driver ( 16 ), which is assigned to the container ( 3 ), for applying force to the cage ( 9 , 10 , 11 ) when the container ( 3 ) is moving in the direction of introduction.
12. The device as claimed in claim 1 , which comprises a vacuum bell jar ( 15 ) that can be fitted from the outside over the container.
13. The device as claimed in claim 1 , which also comprises a driver ( 16 ), which is assigned to a vacuum bell jar ( 15 ) which is fitted over the introducible container ( 13 ) from the outside and/or to guide elements which are introduced from the outside, for applying force to the cage ( 9 , 10 , 11 ) when the vacuum bell jar ( 15 ) and/or guide elements which are introduced from the outside are moving in the direction of introduction.
14. The device as claimed in claim 1 , wherein the cage ( 9 , 10 , 11 ) is held under a prestress that is directed oppositely from the direction of introduction.
15. An installation for the vacuum-coating of the interior and/or exterior surfaces of at least one container ( 3 ), which comprises at least one device as claimed in claim 1 .
16. The installation according to claim 15 , in which the at least one container comprises a bottle.
