Description

Field of invention

The invention relates to a swing top closure for a bottle. In particular, the invention relates to a swing top closure which can be attached to a standard beverage bottle.

Background of the invention

Swing tops for bottles are known. A clip closure includes a plug which can be connected to a lever via a clip. By depressing the lever, the stopper is pressed sealingly onto the edge of the opening of the bottle.

Swing-top bottles usually have two opposite depressions on the bottle neck, into which the ends of the lever designed as a wire engage. This is how a simple camp is formed.

The utility model DE 20 2014 008 591 U1 On the other hand, shows a swing top that can also be attached to standard bottles, i.e. bottles without depressions on the bottle neck.

For this purpose, the closure includes a clamp that can be placed around the neck of the bottle. This can be attached by hooking it underneath the head of the bottle. The joints of the lever are attached to the clamp, through which the bracket can be pulled down together with the stopper and thus pressed onto the opening edge of the bottle.

Task of the invention

The invention is based on the object of providing a clip closure which can be attached to standard bottles and which is simple to construct and comfortable to use.

Summary of the invention

The object of the invention is already achieved by a bottle closure according to claim 1.

Preferred embodiments and further developments of the invention can be found in the subject matter of the dependent claims, the description and the drawings.

According to the invention, a bottle closure is provided, which is designed as a clip closure.

The bottle cap includes a stopper. The stopper can be made of metal, plastic or porcelain, for example, and includes a seal that is pressed onto the bottle.

The stopper can be placed sealingly on the edge of the bottle using a bracket.

The bracket is preferably designed as a bent wire, which is guided through a through opening in the plug.

Bent ends of the bracket work together with the lever to form a bearing.

The bracket can be pressed tightly onto the edge of the bottle by operating the lever.

The lever is connected via two joints to a clamp that can be attached to the neck of the bottle.

Using the clamp, the bottle cap can also be attached to standard bottles.

According to the invention, the clamp can be placed resiliently on the bottle neck. For this purpose, the clamp comprises a substantially circular section which wraps around the bottle by more than 180°. This means that the clamp can be pressed onto the bottle neck from the side below the head of the bottle. The clamp expands according to the diameter of the bottle neck and, when attached, springs back in such a way that it rests against the bottle neck.

The bottle cap according to the invention can therefore be attached to the bottle in a very simple manner.

According to the invention, the joints via which the lever is connected to the clamp can be positioned offset from a central axis of the bottle closure.

A central axis of the bottle closure is defined in that the stopper is circular and therefore has a central axis. When the bottle cap is in place, the stopper and a circular portion of the clamp are aligned on this central axis.

The bottle cap is divided into two areas when viewed from above. Seen from the lever, the bottle cap is divided into a front and a back half.

The axes of the two joints, which can be connected to one another by a virtual line from joint to joint, do not extend through this central axis, but are offset from the central axis. In particular, the virtual connecting line extends offset from the central axis on the side of the closure opposite the lever.

It has been found that this configuration can reliably prevent the clamp, which is only held by the spring force, from coming off when the closure is opened and closed.

This means that the bottle cap according to the invention is not only easy to attach, but can also be operated conveniently. In particular, according to a preferred embodiment of the invention, it is not necessary to hold the clamp when operating the lever.

The clamp is preferably Ω-shaped. The clamp therefore comprises a segment-shaped section which is open on one side. The ends of the clamp are designed as arms, in particular as bent arms of a sheet metal strip.

According to a preferred embodiment of the invention, the ends of the clamp are each designed as folded arms which have a through opening to which the lever is attached.

The through opening of the folded arms, in cooperation with the lever, forms a joint via which the lever is rotatably mounted on the clamp. The two joints lie opposite each other and preferably have a common axis of rotation.

According to a preferred embodiment of the invention, the arms run essentially parallel to one another. In particular, the arms can comprise a substantially rectilinear section, in each of which a through opening is arranged.

According to a preferred embodiment of the invention, the arms are designed to be completely straight starting from the deflection. This embodiment enables a particularly simple production of the clamp as a bent part made of sheet metal.

A turning point is defined by moving the arms. In particular, the relocations can be designed as a circle segment, with the center of the circle defining the reversal point.

Preferably, the reversal point is aligned at an angle α of 15 to 40°, particularly preferably of 22 to 25°, to the central axis.

The axis of the joints and/or the virtual line connecting the joints is, according to an embodiment of the invention, 0.2 to 2 mm, preferably 0.3 to 1.5 mm and particularly preferably 0.5 to 1 mm from the central axis of the shutter.

The clamp wraps around the bottle neck of an embodiment of the invention over a circumferential angle of 200 to 300°, preferably from 220 to 280° and particularly preferably from 240 to 260°.

The lever and/or the bracket are preferably designed as a bent wire.

In particular, the bottle closure can include exactly three other parts in addition to the stopper, namely the bracket and the lever, which are designed as bent parts made of wire, and the clamp, which is designed as a bent part made of sheet metal.

The bottle cap is designed to be particularly simple and robust.

The ends of the lever are preferably first wrapped around the curved ends of the bracket and then engage in the through openings of the clamp.

The sections wrapped around the ends of the bracket form a first joint between the bracket and the lever. The ends of the bracket inserted into the through openings of the arms form a second joint, namely between the lever and the clamp.

During assembly, the lever can be easily connected to the clamp by compressing the clamp and/or by expanding the lever. The two parts are connected to each other by spring-loaded snapping back. It is not necessary for the lever to be secured, for example, by a thickening between the through hole and the annular section of the clamp.

Rather, as is provided in a preferred embodiment of the invention, the lever can be formed entirely from a bent wire with a constant diameter.

The invention further relates to a bottle, in particular a beverage bottle, which is closed with the bottle cap described above.

Brief description of the drawings

• 1 shows a side view of a bottle cap attached to a bottle according to an embodiment of the invention.
• 2 shows the bottle cap attached to another bottle.

• 4 is a cross section of the clamp.

Detailed description of the drawings

1 shows a side view of a bottle cap 1, which is attached to a bottle 2.

Bottle 2 is a standard bottle, such as that used as a beer bottle.

The bottle 2 includes a bottle neck 3 with a thickened head 4 and an edge 5, which can also serve to hold a crown cap.

The bottle 2 is closed by a stopper 10. The stopper 10 can be made of ceramic or plastic, for example. In this exemplary embodiment, the plug 10 includes a seal 12. The seal 12 can be designed, for example, as a sealing ring. In order to be pressed onto the edge 5 by means of a bracket 20, the plug 10 includes the through hole 11 through which the bracket 20 is guided.

The bracket 20 is designed as a bent part made of wire. The bent ends 21 of the bracket 20 are inserted into the lever 30.

The lever 30 includes a U-shaped portion which serves as a handle 31 to open and close the bottle cap 1.

This is followed by a loop 32, into which a bent end 21 of the bracket 20 is inserted. A joint 7 is thus formed between the bracket 20 and the lever 30.

The ends 33 of the lever initially run upwards and are inserted into the clamp 40, which is pushed onto the bottle neck 2 below the head 4.

A joint 6 is thus provided between the lever 30 and the clamp 40.

The lever 30 is also designed as a bent part made of wire.

The clamp 40 is pushed from the side onto the neck 3 of the bottle. The clamp 40 is attached to the neck 3 in a form-fitting manner by springing back.

The clamp 40 is designed as a bent part made of sheet metal.

The joint 6, which connects the clamp 40 to the lever 30, is arranged offset from the central axis m. The central axis m is defined by the bottle 2 and the stopper 10.

Due to the offset arrangement of the joints 6, the clamp 20 does not jump off the neck 3 of the bottle 2 even when the handle 31 is moved upwards.

Due to the resilient design of the clamp 40, it can adapt to different diameters of the neck 3 of the bottle 2.

As in 2 shown, the same bottle cap 1 can also be attached to a bottle 2, which is opposite the one in 1 The bottle shown has a more bulbous design, which is accompanied by a slightly larger diameter of the bottle neck.

3 is a cross section in the area of the neck 3 of the bottle.

In this illustration it can now be seen that the clamp 40 is Q-shaped.

The clamp 40 includes a circular section 44 which is open to one side. On this side there are folds 43 on which the metal strip changes direction and forms an arm 41 which lies opposite the annular section.

The arms 41, which are straight in this exemplary embodiment, each include a through hole 42 into which the bent end 33 of the lever engages.

This is how a joint is formed.

4 is a cross section through the clamp 40.

The annular section 44 merges into the arms 41 via the ring segment-shaped folds 43 in this exemplary embodiment.

The deflection can have a diameter ru between 1 and 4 mm, preferably between 1.5 and 3 mm.

In this exemplary embodiment, the arms 41 lie parallel to each other and are straight.

Through the through hole 42, a joint (6 in.) is formed in cooperation with the lever 1 ) educated.

The central axis of the joint, which corresponds to the central axis of the through holes 42, is spaced from the central axis m of the bottle closure by the distance a, preferably by 0.5 to 1 mm.

The joints provided by the through openings 42 can be connected to each other by a virtual line. In this exemplary embodiment, the axis of rotation of the joints lies on this virtual line.

The through holes 42 can have a diameter between 2 and 4 mm.

The circular section 44 may have a radius rs of 10 to 18, preferably 12 to 14 mm.

The folds 43 assume an angle α of preferably 22 to 25 ° to the central axis.

The angle β over which the clamp 40 extends beyond the central axis m is 30 to 40° in this exemplary embodiment. Accordingly, the clamp 40 wraps around a circumferential angle of 240 to 260°.

4 shows the clamp 40 in its initial state. When pushed onto the neck of the bottle, the clamp expands and springs together again when fully attached.

The invention made it possible to provide a very simple and robust clip closure, which is also comfortable to use.
