Definitions

  • the present invention relates to a closure device for a liquid container such as a bottle or gourd body.
  • the gourds allow the transport of liquids, in particular to take a drink to the place of the practice of a sporting activity or to school. They generally include a container intended to receive the liquid and a removable closure system coupling to the container.
  • a closure system comprising a fixed ring intended to be mounted on a bottle body, the ring carrying a shutter extending in a neck which is axially movable.
  • the shutter closes the orifice of the neck. Pressing on the neck releases the shutter from the orifice of the neck to access the liquid.
  • a seal can be arranged under the shutter to improve the seal in the high closed position.
  • a spring is interposed between the neck and the ring to urge the neck in the high closed position.
  • This closure system is intuitive and also allows the bottle to be sealed tightly.
  • the gap between the shutter and the neck can jam the lips or the tongue of the user, which can interfere with the use of the bottle, in particular by young children.
  • this closure system has a relatively large number of parts, which increases its cost and complicates the disassembly and assembly of the system for cleaning.
  • US2007181523 describes a known closure system according to the preamble of claim 1 attached.
  • One of the aims of the present invention is to provide a closure device for a container exhibiting an actuation which can be easily performed, in particular by young children, exhibiting good sealing quality and comprising a limited number of parts.
  • the subject of the invention is a closure device for a liquid container as described in claim 1.
  • the membrane can thus be opened by axial thrust from the neck.
  • the closure device is easy to operate, so it is easily understood from an early age.
  • the membrane allows the closure device to present a good seal.
  • the closure device has a limited number of parts. It is completely removable and easy to clean.
  • the neck can be mounted to move on the base between a high closing position and a low opening position over an axial stroke allowing that in the low open position, the membrane resiliently urges the neck to return to the high closed position. .
  • the neck returns to the high closed position. This allows the gourd to be closed tightly when the gourd is not in use.
  • the membrane then plays, on the one hand, the role of a seal and, on the other hand, the role of a return spring in the high closing position of the neck away from the base.
  • the figure 1 shows a closure device 1 for a container 2 of liquid, such as a body of a bottle or gourd, for example made of plastic material, allowing in particular the transport of a drink.
  • a container 2 of liquid such as a body of a bottle or gourd, for example made of plastic material, allowing in particular the transport of a drink.
  • the closure device 1 comprises a base 3 intended to be mounted on the container 2, for example in a removable manner, a neck 4 movably mounted on the base 3 between a high closed position in which the liquid cannot leave the container 2 ( figure 2 ) and a low opening position in which the user can access the liquid ( figure 11 ).
  • the base 3 comprises a base 5 and a tube 7.
  • the base 3 is preferably made in one piece, for example of plastic material.
  • the base 5 has an annular portion, the interior of which carries a fixing means 6, such as a complementary screw thread to the container 2, configured to reversibly secure the base 3 to the container 2 ( figure 2 ).
  • the base 5 is closed radially around the tube 7 by a wall 9, for example plane of the base 5 and perpendicular to the axis of the tube 7, the tube 7 projecting from the wall 9 on the side of the neck 4, for example centrally in relation to the plinth 5.
  • the base 5 can also carry an articulation member 10 and a locking element 11 intended to cooperate with a cover (not shown) pivotally mounted on the base 3.
  • the hollow tube 7 is intended to be placed in communication with the interior of the container 2. At least one orifice 12 is formed in the tube 7, for example at an axial end 13a of the tube 7. The tube 7 thus passes through the base 5 so that once the base 3 is mounted on the container 2 and the neck 4 in the lower open position, the liquid can flow through the tube 7.
  • the closure device 1 further comprises an elastic membrane 14 arranged in an opening 15 of the neck 4 ( figures 5 and 6 ).
  • the membrane 14 has the general shape of a disc complementary to the circular opening 15 of the neck 4.
  • the membrane 14 comprises at least one slit 16 closed on itself in the rest position when the neck 4 is in the upper closed position, thus obstructing the opening 15 of the neck 4 in a sealed manner.

  • the annular groove 17 is for example formed in the membrane 14 ( figure 6 ) and the annular rib 18 is formed in the opening 15 of the neck 4 ( figure 5 ) Or vice versa.
  • the annular groove 17 and the annular rib 18 allow the tight fitting and maintenance of the membrane 14 in the opening 15 of the neck 4.
  • the membrane 14 can be easily disassembled in order to be cleaned and possibly replaced.
  • the tube 7 is arranged at the rear of the membrane 14 in the high closing position of the neck 4 so that the lowering of the neck 4 towards the base 3 in the low opening position in the axial direction of the tube 7, opens the membrane 14 by deformation of the at least one slot 16 by the axial end 13a of the tube 7. More precisely, the axial end 13a of the tube 7 engages through the at least one slot 16 to open the membrane 14 ( figures 10 and 11 ).
  • the axial end 13a of the tube 7 thus deforms the elastic membrane 14 to free a passage for the liquid ( figures 2 and 11 ).
  • the neck 4 is movably mounted on the base 3 between a high closing position and a low opening position on an axial stroke d allowing for example that in the low opening position, the membrane 14 resiliently urges the return of the neck. 4 in high closed position ( figure 2 ).
  • the axial stroke d can be between 4mm and 6mm, such as of the order of 5mm.
  • the high position of the neck 4 moves the tube 7 away from the membrane 14 which returns to a rest position, closed on itself. So when the user releases the pressure exerted on the neck 4, the neck 4 returns to the high closed position. This allows the gourd to be closed tightly when the gourd is not in use.
  • the membrane 14 then plays, on the one hand, the role of a seal and, on the other hand, a role of a return spring in the high closed position of the neck 4 away from the base 3.
  • an additional elastic member 19 such as an elastic blade or a helical spring, interposed between the neck 4 and the base 3 to urge the neck 4 in the high closing position (dotted on the figure). figure 2 ).
  • An additional elastic member 19 makes it possible to secure the return to the high closing position independently of any wear of the membrane 14. The closing device 1 is thus urged into the high closing position when no pressure is exerted on the neck. 4, by biasing the membrane 14 and / or by biasing the additional elastic member 19.
  • the annular groove 17 can be formed in asymmetric annular beads 45, 46 of the membrane 14, the inner bead 45 (side containing 2) being thicker than the outer bead 46, the inner bead 45 cooperating with a complementary shoulder 47 of the neck. 4 ( figures 5 and 6 ).
  • This asymmetry of the membrane 14 allows it to be more difficult to push out from the inside than to push out from the outside of the container 2. The membrane 14 can thus be removed more easily when it is pushed by the. user from outside the neck 4 only when it is pushed by the tube 7.
  • the at least one slot 16 is formed in a flat wall 20 of the membrane 14 ( figure 6 ).
  • the wall 20 is for example arranged in at least one recess 43a, 43b of the membrane 14, the recess 43a, 43b here forming an annular step in the membrane 14.

  • the wall 20 is arranged in two recesses 43a, 43b of the membrane 14. , formed in the two opposite faces of the membrane 14.
  • the at least one recess 43a, 43b creates a zone of rigidity which favors the return of the membrane 14 to the rest position, which improves the quality of the elastic return of the membrane 14 to the high closed position.
  • the orifice 12 of the tube 7 located at the axial end 13a of the tube 7 can thus be closed by the membrane 14 in the high position of closing ( figure 2 ).

  • the membrane 14 further comprises here two slots 16 which intersect perpendicularly in a cross ( figure 7 ).
