CONTAINER LOCK

The invention relates to a closure for containers, in particular bottles, with the features mentioned in the preamble of claim.

French patent application 81 15 014 by the same applicant relates to a closure in which the mouth a container thereby closed or. is opened that a movable part is axially opposite a fixed part of the Shutter is moved back and forth. An axially deformable, thin wall connects the two named parts. The wall serves to keep the moving part in relation to the fixed part lead and ensure a stable opening and closing position for a stopper.

According to the present invention, the closure has an in axial deformable wall, which is frustoconical or is curved and tapers downwards. (Terms such as "bottom" and "top" refer to a closure that is placed on, for example, an upright bottle is attached.) The deformable wall can assume two stable positions. In one it tapers upwards, in the other down.

The invention aims to improve the known closure be achieved. For this purpose, a limited axial deformation of the deformable wall is intended to be significant cause axial force in the sense of a locking acts from top to bottom.

The tight sealing of the container is achieved by mutual contact under axial pressure of the non-cylindrical Achieved surfaces of a plug and a container. This is well known and is used with screw caps, elastic snap closures, crown caps and others Closures applied.

In French patent 2 007 840 by the same applicant a closure is described in which a flexible closure bottom, which is curved upwards and is connected to an annular sealing zone which extends radially over the Outer surface of a provided on the end base axially downwardly directed cylindrical body protrudes, a train exercises the annular sealing zone and presses it against an annular, non-cylindrical area which is located on the Inner surface of the muzzle is located.

According to the present invention, a significant one secures axial closing force created by a limited deformation of the deformable wall creates a completely tight seal and enables the seal to be used on containers holding liquids or gases under pressure contain.

According to the invention, the central part of the deformable wall should be rigidly connected to a plug that is above this wall is arranged and cooperates with a mouth which is formed by an upwardly directed cylinder wall and has a diameter the same size as or greater than the diameter of a cylinder sleeve which holds the closure on an outer annular bead of the container.

Such a closure is particularly applicable to containers with small annular bulges, like medicine bottles made of glass, in which it is expedient to

to enlarge the plug's knife.

According to the invention, the stopper is secured against loss, and there will be a large passage cross-section for the dispensed Product guaranteed with the cap open.

According to the invention, a closure is created in which a simple pressure without any special effort creates a dense one Closing causes that is simply constructed and a single or two rigidly interconnected locking parts contains.

A further development of the invention relates to a closure, which has two rigidly connected plugs which are arranged above and below the deformable wall, whereby a double seal is achieved on two mouths arranged one above the other.

In this case, a metering device can be created which is capable of dispensing equal and constant amounts of liquid serves.

A further development of the invention allows a safety lock, in particular, create a child-proof lock.

By using a destructible element, a guarantee seal can be created in which the element is up to its destruction blocks the moving part of the lock in the closed position.

Hygienic use can be ensured, i. H. without contact with the product to be dispensed.

Embodiments with further features of the invention are described below with reference to the drawings.

Figure 1 to 3 are axial sections through closures according to the Invention and show the closed position to the left of the vertical axis and its open position to the right. In detail:

Figure 1 shows a closure that two rigidly together having joined elements, one of these two elements in the form of a flat partition is attached to a tamper-evident band by means of tearable or frangible connectors.

Figure 2 shows a closure in which the middle section of an axially deformable wall rigidly with is composed of a hollow plug which is arranged above the mentioned wall and with a Muzzle cooperates inside an upwardly directed cylindrical wall.

FIG. 3 shows a closure in which the plug sits above an axially deformable wall and is rigid with it connected to another plug, which sits below this wall, and the two plugs so can be actuated that the open position of the upper stopper is the closed position of the lower stopper is equivalent to.

FIGS. 4A and 4B show a child-resistant one in axial sections Lock in different operating positions. A closure plate arranged transversely to the axis can be in the axial direction freely on an operating rod move and is pressed by a return element in its upper position, in which it has a head of the actuating rod covered.

The same or equivalent elements have the in all figures same reference numerals.

According to Figure 1, the hollow stopper 1 has a flat bottom 2, which merges into a cylindrical body 3. The stopper is directed downwards, i.e. open at the top and formed in one piece with a frustoconical wall 4, which on its The circumference is connected to a downwardly directed cylinder sleeve 5 and to an upwardly directed cylinder wall 6. The cylinder wall 6 forms a mouth of the closure.

An annular groove 7 on the inner wall of the sleeve 5 is under a press fit connected to the corresponding outer surfaces of an annular bead 8. As a result, the closure is in a known manner attached under seal on the annular bead 8 of a container B.

On the upper surface of the flat bottom 2, namely in its Middle, attaches a central, upwardly directed rod 9. The top of the rod is snap fit joined together with elastic relaxation with a transverse wall 10, which on its periphery by tearable or frangible Connecting pieces 11 are connected to a guarantee strip 12.

To the left of the vertical axis in FIG. 1 is the guarantee strip 12, which has an annular shoulder 13 inside, hooked on the edge of a circular shoulder 14, which is attached to the cylindrical External surface of the wall 6 is provided. Right of the vertical axis is the same lock in the open position shown without the previously torn guarantee tape. The contents of the container can in the direction of arrow M through Openings 15 in the frustoconical wall 4 emerge.

The guarantee elements can be changed in very different ways

realize. E.g. a cap made of metal or plastic, as used in wine bottles, above Closure according to the invention are attached, with only access to the rod 9 with destruction of the transverse wall of the cap receives, which makes it possible to open the shutter.

The frustoconical wall 4 is elastically deformable and holds the stopper 1 either with elastic residual tension in the closed position (left) or in the open position (right). Under You can snap action by hand using the rod 9-off move one to the other.

In Figure 2, a hollow plug 1 'is above the truncated cone shaped wall 4 is provided. The stopper has a flat one Bottom 2 ', which is surrounded by a cylindrical body 3' which is itself provided with an outer annular bead 16. The plug 1 is firmly connected by elastic snap connection to a sleeve 17, which is in the middle of the frustoconical Wall 4 is provided. This wall has openings 15.

In its closed position (on the left in Figure 2) the stopper 1 'closes the container tightly, through the interaction of the outer wall of the cylindrical body 3' with the inner wall of the cylinder wall 6 on the one hand and the transverse wall of the base V and the annular bead 16 on the other hand press against the corresponding walls of the sleeve 5 and the cylinder wall 6.

The opened lock (on the right in FIG. 2) has the same effect as that of FIG. 1.

If the sleeve 17 according to FIG. 2 is given the shape of a plug 1 According to Figure 1, a closure according to the invention is obtained, with two stoppers with an opening 6a inside the cylinder wall 6 and cooperate with an opening within the annular bead 8 of the container.

The closure according to Figure 2 has the following advantages:

1. Using the fastener on an annular bead of very small diameter, which is made possible by creating an opening within the wall 6 of larger diameter the said mouth cooperating with the plug 1 'above the frustoconical wall is arranged.

2. A radial seal between the plug 1 'and the Orifice 6a, both of which are made of injection-molded plastic, is easier to achieve than a seal between a stopper and a mouth of a glass container.

3. The axial seal is made by two transverse Achieved surfaces of the plug which are axially pressed against two corresponding surfaces of the mouth.

4. Two stoppers, in the same cap, double the sealing means.

5. By the fact that the closure has two plugs, one above of the other, can easily be a metering device realize.

According to FIG. 3, a removal closure with a metering device is realized by a closure according to the invention with two stoppers which are arranged one above the other. The lower stopper 1 has a flat bottom 2 with an outer annular bead 18 and an elongated cylindrical body 3 which merges in one piece into a frustoconical wall h which slopes inward in FIG. 3 on the left (closed position). The wall A merges in one piece at its outer circumference into a cylinder sleeve 5 which is connected to the mouth of the container B by a snap connection at the bottom. The closure has an opening 6 a within a cylinder wall 6.

A second hollow stopper 1 ′, which is similar to that according to FIG. 2, is arranged above the frustoconical wall 4. It is rigid with the plug 1 by a coaxial tube 19 _r-jointed, which is integrally formed with a plug (here with the plug 1 ').

The cylindrical body 3 of the stopper 1 has through openings 20, which in the closed position (left in Figure 3) a connection from the container contents to a metering chamber D represent, which is limited by the bottoms 2 and 2 ', the The outer wall of the tube 19, the inner wall of the cylindrical body 3 and the upper wall of the truncated cone wall 4.

If the container is tilted, the liquid fills the Dosing chamber D, while the plug 1 ', which is in its mouth 6a slides outwards into the open position, its volume increased. At the moment when the stopper leaves its mouth and opens a way to the outside, the openings 20 blocked off from the inside of the container by interaction of the bottom 2 with its annular bead 18 and the annular bead 8 of the container (right in Figure 3). Only those in the Liquid present in the dosing chamber can be dispensed.

The dimensions of the metering chamber D can be increased by a plug 1 'and a cylinder wall 6 of larger diameters.

FIGS. 4A and 4B show a child-proof lock with a handle bar 9 ″. It is used to open the lock required, two consecutive and coordinated movements that a toddler is usually unable to perform in the required order. One must namely press a shutter plate 21 down and on it pull the handle bar 9 "upwards.

zel-48-de

A return member 22 (here a compression spring) holds the closure plate 21 in its upper position or brings it into this position. The return member 22 is preferably in one piece formed either with the closure plate 21 or with the stopper 1. It can take the form of a compression spring, from resilient tongues, an elastic sleeve or other elements to have.

FIG. 4A shows the closed position with the closure plate on the left 21 in its upper position, in which a head 23 of the handle bar 9 ″ is located in the interior of a recess 24 in the middle of the closure plate 21. FIG. 4A shows the closure plate on the right 21 of the still closed closure in its lower position, in which the head 23 is exposed and won outside can be seized.

FIG. 4B shows the same closure on the left after the stopper is open, the closure plate 21 is still below the head and the handle bar 9 "still releases. FIG. 4B shows the opened lock on the right, in which the released lock plate is pushed upwards by the spring member is printed and surrounds the head of the handlebar with its recess.

The illustrated and described arrangements and parts can be modified within the scope of the invention.

For example, a plug with threaded ribs can be arranged above a flexible wall which is frustoconical or shaped is curved at the bottom, the plug being held axially on the center piece of this wall but freely about the longitudinal axis this wall can turn. The plug can then be arranged so that it is on the upstanding cylinder wall, the is threaded, can be screwed.
