Abstract

The stopper device according to the invention comprises an intermediate chamber 15 arranged at the free end of the neck 2 of a bottle 1. This chamber is delimited at its upper part by an elastic membrane 14 mounted to rotate relative to the axis of the bottle. neck. At its lower part it is limited by a fixed bottom 10 pierced with two inlet openings 16 of the chamber. An outlet orifice 18 of the chamber 15 is arranged at the center of the membrane 14 and a boss 17 located opposite the outlet orifice 18 on the bottom 10 closes the latter. The membrane 14 comprises protuberances 19 which partially penetrate into the inlet orifices 16 and block them causing the device to lock. The rotation of the membrane 14 by acting manually on the skirt 12 of the mobile capsule 6 causes an elastic deformation of the membrane and unlocks the device, placing the interior of the bottle and the chamber 15 in communication through the inlet orifices 16. By increasing the pressure beyond a determined value inside the bottle, the deformation of the membrane 14 is increased and the outlet orifice 18 is released from the boss 17, the device then being in the open position.

Description

The present invention relates to a device

  capping especially for flexible bottle.

  Many sealing systems are known for such bottles. Patent FR-2 350 272 discloses a plug for a flexible or rigid bottle composed of a cap head having a fixing skirt for mounting on a bottle or other container, the cap head has a recess whose bottom has an opening and a boss forming a fulcrum,

  and a lid connected to the cap head by a system

  toggle to hold the lid in the closed position without it protruding from the upper side of

  the cap head and in the open position in the-

  a shutter releases the opening, the passage to the open position taking place by exerting a

  pressure on the lid in the region of the char-

  to enter the other side of the neck.

  vercle. With such a device, manual intervention is necessary to obtain the opening. In

  this position, the product may flow out

  the bottle unexpectedly, for example by accidentally spilling the bottle. It is necessary to intervene manually on the device for the

close it.

  The object of the invention is to avoid these drawbacks

  vantages. For this purpose, the subject of the invention is a closure device for a bottle equipped with a neck

  characterized in that it comprises a chamber inter-

  median arranged at the free end of the neck

  communicating with the interior of the bottle through an inlet port and with the outside through an outlet port which is closed by a valve member whose opening

  is controlled by an increase in the pressure re-

  in the bottle beyond a certain value.

  Thanks to this arrangement, a simple pres-

  flexible bottle allows you to use the content

of it.

According to other characteristics:

  - the chamber is delimited at its upper part

  by an elastic membrane in which is

  the co-operating outlet, when the pressure

  sion is less than the determined value, with a corresponding closure element formed vis-a-vis

  on a bottom delimiting the chamber at its lower

  and in which the inlet port is provided; - The membrane is circular and the outlet orifice is located in the center thereof and cooperates with

  the closure element which is a central boss pre-

  seen on the inner side of the room.

  The relaxation of the pressure on the walls

  of the bottle results in the systematic closure of the

  stoppering. However the risk of escape

  Unexpected product remains. That is why

  This invention also presents the characteristics

following questions:

  - Locking means controlled manually

  noisily allow to close the inlet port; - The locking means are constituted by a closure member rotatably mounted about the axis of the neck between a locked position and an unlocked position; - The closure member is constituted by a protuberance formed on the inner wall of the elastic membrane and the latter is rotatably mounted around the neck; the protuberance has a shape adapted to partially engage in the inlet orifice

  and sealing it in the posi-

  locked under the action of the elastic membrane

tick;

  the protuberance has a sensory profile

  spherically to facilitate its disengagement from the inlet port by rotation of the elastic membrane; the chamber comprises a circular bottom in which are arranged a plurality of inlet orifices distributed in an annular zone surrounding the central boss and the elastic membrane comprises several protuberances cooperating respectively with each of the

  inlet ports in locked position.

  The device according to the invention thus makes it possible to avoid the unexpected escape of product when it is in place. The present invention furthermore has the following characteristics: a membrane is integral with a skirt surrounding the neck and having latching means co-operating with a fixed part for

  immobilize the membrane axially with respect to the gou-

  lot; - The latching means are constituted by an annular rib on the inner face of the

  skirt and the fixed part is an annular rib ex-

  dull coming from matter with the neck; - The latching means are constituted by an annular rib on the inner face of the skirt and the fixed portion is the lower end of a sleeve surrounding the neck and integral with the

  bottom of the chamber, said sleeve comprising

yen hanging on the neck.

  The invention will be described in more detail below with reference to the accompanying drawings, given by way of example and in which: Figure 1 is an axial sectional view of a closure device according to the invention shown - felt in locked position; - Figure 2 is a partial sectional view of the closure device of Figure 1 shown in unlocked and closed position; - Figure 3 is a partial sectional view of the closure device of Figure 1 shown in the open position;

Figure 1.

  In Figure 1 is shown a bottle

  1 having a neck 2 provided with an external rib

  3. A closure device 4 according to the invention mouth the neck 2. This device comprises a fixed capsule 5 attached to the rib 3 and a mobile capsule 6

in rotation.

  The fixed capsule 5 comprises a cylindrical sleeve

  external sleeve 7 extending parallel to the outer wall of the neck 2. This sleeve has an internal shoulder 7a which ensures, in cooperation with the rib 3, the attachment of the sleeve 7 on the neck 2 and its

  axial immobilization with respect thereto. The cap

  fixed sule 5 also comprises an annular portion 8 having a conical outer surface adapted to the inside diameter of the neck 2 to plug the bottle and ensure immobilization in rotation of the capsule

fixed 5.

  The sleeve 7 of the fixed capsule is extended

  by an annular ring 9 upper whose edge li-

bre has a chamfer.

  The lower edge of the ring ferrule 9

  is connected to a bottom 10 which closes the opening of the gou-

lot 2

  The movable capsule 6 comprises a cyan skirt

  lindrique 12 adjacent to the sleeve 7 provided to its ex-

  lower end of an internal flange 13 of

  ratcheting that cooperates with the lower end of the

  muff. The capsule 6 has at its upper end

  a transverse elastic membrane 14.

  This membrane 14 has a substantially spherical curved profile. The peripheral edge of the convex face of the membrane is in sealing contact with the chamfer of the annular shell 9 of

the fixed capsule 5.

  The membrane 14, the annular shell 9 and the bottom 10 define an intermediate chamber 15. The

  bottom 10 has two inlet ports 16 diametrically

  the opposite. Furthermore, it has on its inner face, that is to say turned towards the interior of the chamber 15, a central boss 17 in the form of a cap

spherical.

  The membrane 14 further comprises a central outlet orifice 18 which cooperates with the boss 17 of the bottom 10 to close the chamber 15 when the pressure inside the bottle is less than a value.

determined.

  The invention comprises locking means

  lage. For this purpose, the membrane 14 which constitutes the upper wall of the chamber 15, comprises two

  protuberances 19 located on its internal face facing

  10. Each protuberance has the general shape of a hemisphere whose position and radius are adapted so that each protrusion 19 closes each inlet port 16 vis-a-vis partially penetrating into these when the device is in its locked position shown in Figure 1. In the locked position, the inlet and outlet openings 16 of the chamber 15 are closed and the engagement of the protuberances 19 in the

  inlet ports 16 locks in rotation the

  in this angular position.

  To move from the locked position to the unlocked position shown in Figure 2,

  exerts a couple on the mobile capsule 6 in order to pro-

  V rotation of the movable capsule 6 relative to the fixed capsule 5. The torque is exerted against the retaining force in the locked position due to the elastic biasing of the protuberances 19 in the orifices 16 by the elastic membrane 14 As soon as

  torque is greater than the restraint effort, it provokes

  that a deformation of the elastic membrane which

  causes protuberances 19 to exit outlets 16 to bear on the internal flat surface

from the bottom 10.

  In this position, the device is de-

  locked and room 15 communicates with the

  bottle 2 through the inlet ports 16.

  In this unlocked position, an increase

  the pressure prevailing inside the fla-

  con 2 beyond a predetermined value, for example by pressing on the flexible wall of the bottle causes deformation of the elastic membrane 15 which rises

  and a clearance of the boss 17 with respect to the orifice

  18, as shown in FIG.

  duit can then leave the bottle 1 through the orifice of

  Exit 18 after crossing the room 15.

  As shown in Figure 4, a provision

  capping system as described above may

  put the mounting of the closure device according to

  the invention between vial 2 and another vial

  presented in dashed lines thanks to the surface

  external device of the mobile capsule 6.

  Such an arrangement makes it possible, for example, to

  make an extemporaneous mixture of two products.

  According to the variant represented in FIG.

  the rotation of the mobile capsule 6 can be limited.

  In this case, a longitudinal rib 20 is provided on the inner face of the skirt 12. It cooperates with a rib 21 on the outer face of the sleeve 7 and with a notch 22 which is intended to maintain the

  device in its unlocked position.

  The closure system according to the invention provides, because of the snap of the movable capsule 6 on the fixed capsule, a significant resistance to

  any attempt to remove the moving capsule 6.

  This will not be released during the flow

product out of the bottle.

  Moreover, the need to unlock the device by rotation of the mobile capsule, before the product can flow outside the

  bottle prevents any unwanted or unintended

tif.

  The predetermined value is a function of the elastic constant and the surface of the membrane on which the liquid or the gas inside

  of the bottle communicating with the chamber 15.
