Applicant; Reckitt and Colmann (Overseas) Limited,, Hull. Densom Lane (England) container closure

The invention relates to a container closure in which the the mouthpiece which has the removal opening and is designed as a fold oalg the fixed 'closure body covered and a cap is screwed on.

In some known container closure of this type, the bellows is threaded so that a closure cap over the bellows can be stolen. This cap knows an inner, conical annular surface, which is assigned an outer conical iiingflache of the head part of the mouthpiece. Kick an overpressure in the container or becomes the (elastic) container pressed, the part of the bellows not covered by the thread of the cap can expand, so that the outlet opening is released and part of the container contents can escape into the cap. Apart from the fact that this contamination of the Cap interior is undesirable, there is also the risk with this known construction that part of the container contents in the Au3 <anraum exits; because a good sealing effect between the inner conical ring surface of the cap and the outer conical ring surface of the head part of the mouthpiece is screwed together Do not allow the cap to reach the flexible, i.e. not overly rigid, bellows.

The object of the present invention is the known per se

To arrange cap in such a way on the container closure that the from Internal pressure in the container dependent, from mouthpiece and closure body formed closure is locked by the releasably applied cap in the closed position.

This object is achieved by a container closure. In which the removal opening is designed as a bellows Mouthpiece covers the fixed breech body ' and a cap is screwed on, and which is characterized according to the invention in that the cap can be detached from the base of the mouthpiece, overlapping the mouthpiece up to its base (but not necessarily separable) is connected and. has an inner stop to which an outer stop of the head part of the Mouthpiece is assigned.

- The detachably attached to the base of the mouthpiece, For example, screwed-on cap lies with its inner Stop (shoulder) on a corresponding outer stop (shoulder) of the head part of the mouthpiece / thus locks the mouthpiece in relation to the fixed closure body in the closed position » If the cap is removed, it is designed as a bellows Mouthpiece released. It then either remains in the closed position, from which it is lifted by internal overpressure in the container, or it lifts itself automatically due to its elasticity of the bellows from the closure body into the open position, so that the container contents, for example a liquid, can also be poured out of the container without internal overpressure *. ■, · ■. ..

The arrangement of the cap on the fixed base of the as Bellows trained mouthpiece and not on the bellows itself is a greater strength of the releasable connection of the Guaranteed cap with the rest of the container closure.

To be able to unscrew the cap, it has an advantage an internal thread which is assigned an external thread on the base of the mouthpiece. - .. ^

In many cases it will be advantageous according to a preferred one Embodiment of the present invention comprising the head part of the mouthpiece as the elongated closure body to form elongated nozzle.

In particular with such an elongated design of the Closure body and the head part, the cap advantageously has an annular shape, so it is within its: "inner shoulder open so that the nozzle is exposed at all times, whereby the opening, Closing or adjustable opening of the flow by adjusting the annular cap to a desired distance from Container can be reached.

In order to achieve a good sealing effect, points are advantageous the closure body has a conical tip to which an outwardly conically narrowing removal opening is assigned.

The closure body is advantageously attached to a part of the mouthpiece that extends from the head part through the bellows is separated, and preferably on a narrowing of the base of the Mouthpiece.

The container closure according to the invention is particularly simple produce if, according to a preferred embodiment of the present invention, the closure body is integral with the base of the mouthpiece is formed.

In the drawings, an advantageous embodiment of the invention is shown. Show it:

In Figures 1 to 6 of the drawing, 1 denotes a blown plate for liquid shoe cleaning agent. The bottle consists of thermoplastic material and has a mouthpiece 2 ax, on the upper part of which a head part 5 with a central removal opening 10 is provided in a liquid-tight manner. This head part 5 has a socket 6 on its surface, into which an absorbent cushion J is inserted. The fit 6 is offset radially inward from the outer edge of the head part 3, so that an outer shoulder 8 remains, against which an inner shoulder 9 abuts on the inside of the cap j5 as shown in FIG.

fits. A ring shoulder 2;) surrounds dee on the underside; Headboard 5 the opening 10 centered around the closure body keep.

The base 15 of the mouthpiece 2 carries a multi-thread External thread 16 to which an internal thread 17 of the cap 3 is assigned is. A four-start thread is shown.

The closure body 1> (cf. FIGS. 4 to 6) has a bridge 14, past which the liquid can flow to the upper part 4 of the mouthpiece 2. Two wings 19 and 20 arranged opposite one another hang down from the bridge \ k , each wing being provided with an arcuate cutout 21. The space between the wings 19 and 20 extends upwards to below the conical tip 12 of the closure body, in this way to form a V-shaped groove 22 which extends somewhat into the underside of the bridge 14.

Between your upper part 4 and the base 15 of the mouthpiece 2 is a one-piece with parts 4 and 15 compliant bellows 18 are provided. This bellows 18 extends radially inward in the direction of the closure body 13 in the space between the bridge Vi and that of the Bridge hanging down wings I9 and 20. It is located the bridge 14 fx'ei over the bellows 18, 'when the container closure is open.

A constriction 26 is located below the bellows 18 on which see the cutouts 21 of the wings I9 and 20 are supported and secure the closure body against movement when the bellows 18 is compressed.

The conical tip 12, the bridge 14 and the wings I9 and 20 of the closure body are made of a part made of flexible material, such as polyethylene or polypropylene. The llille 22 on the underside of the bridge 14 allows the closure body from below into the mouthpiece, whereby the

6AD ORIGINAL

Wings 19 and 20 slide along the constriction 26 and the The closure body assumes the shape shown in FIG. Afterward The cutouts 21 snap into place on the constriction 26 according to FIG. 1. The sacrificial body returns more easily into his own relaxed position back when the bridge 14 is pressed down on the top of the bellows 18 during insertion, so that the bridge is flattened again and the wings swing outwards.

If one sets according to B ¹ Ig. 2 on the mouthpiece 2 the cap j>, so its shoulder 9 abuts against the shoulder 8 of the head part 5 and the threads 16 and 17 interlock. When the cap is tightened on the mouthpiece 2 by means of ^{1 of} the thread, the head part 5 is moved against the base 15 of the mouthpiece, and the angle of the bellows 18 is reduced. This has the effect that the conical tip 12 of the closure body 13 closes the opening 10.

A displacement of the closure body 1j5 in such Closing movement is achieved by the cooperation of the wings I9 and 20 prevented with the constriction 26 of the mouthpiece.

When the liquid is to be used again, the cap is removed and the suspension of the bellows 18 lifts the Head part 5 from the closure body I3, so that liquid on the closure body 15 can flow over to the pillow 7.

The closure body I3 could also be hollow and thin-walled be; the groove 22 would then not be required because of the flexibility the wall is then large enough to enable the bridge 14 to be folded up.

Figs. 7 and 8 show another form of the closure body ". A circular disk 27 is provided with four symmetrical holes 28 provided to the liquid zürn upper part 4 of the mouthpiece -2 to let flow. Two opposing pairs of wings 29 and 30, which hang down from the window 27 ... are shown in FIG. 8 offset against each other. Each wing is roughly triangular and points

a circular cutout 31 at the outer tip. At the bottom is the disc 27 with a between the wings Transverse groove 24 is provided, and on the other hand, the closure body is cut at 25 in the vicinity of the connection of the "" disk 27. It can be seen that the closure body shown in FIGS. 7 and 8 are bent according to the dash-dotted lines in FIG can so that it passed through the bellows 18 of the mouthpiece can be.
