2. TECHNICAL PROBLEM The problem of closing bottles containing smaller quantities of wine or other fluids with crown caps is very well known. The problem is particularly present in small, family wine cellars, where a limited quantity of wine or other liquid is to be kept in well closed bottles. Such bottle cappers should be cheap and simple for use.

3. STATE OF THE ART Presently in the market there are available several such crown cappers intended for smaller wine and other producers. They are made of metal or combination of metal and plastics. There are versions that are to be fixed on a flat surface (bench, table). The bottle to be capped and the cap are to be placed under the capper jaws that are lifted and lowered manually, by means of a lever, while the bottle is held in place with the other hand. In the market, there is also available a modified, twin-lever, version where the levers are to be held with both hands and where the force is transferred via jaws to the cap.

The present cappers shortcomings are the necessity of holding the bottle with a hand, compiicated handling, the necessity of fixing some of them against a surface and their taking space in the working room. Handling such cappers is slow.

4. DISCLOSURE OF THE INVENTION The invention is primarily aimed to improving crown cappers in a way that will enable fast and safe capping, not requiring holding the bottle with a hand. The crown capper, according to this invention, enables capping of bottles with crown caps by hitting the capper anvil with a hard object or pressing the capper pusher manually. The capper consists of a body with guide that is held against the bottle neck, a cylinder through which there moves a specially designed elastic piston, a conical part of the cylinder for the cap, a permanent magnet and a spring that, after capping, returns the piston and the cylinder into the initial position.

DETAILED DESCRIPTION OF THE INVENTION EMBODIMENT The crown capper as shown in Fig. 1,2,3 and 4 consists of: body 1, body stopper 3, cylinder 4, elastic piston 8, spring 13, permanent magnet 12, depressing screw 14, anvil 6 and pusher 7. Movement of the piston in the cylinder is limited by the piston side openings 9 placed on its opposite sides and the depressing pin 14 fixed to the cylinder 4. The body 1 glides freely along the cylinder 4 to the body stopper 1. The pusher 7, shown in Fig. 4,12 and 13, with the connector 17 enters the anvil 6, whereas between them there is the plate 18, making a part of the pusher 7.

The capper is operated as follows : the body 1 is held with one hand, while a crown cap 19 is placed into the crown-cap conical opening 15 in the cylinder 4 with the other hand, the crown-cap 19 being held by the magnet 12. The crown cap 19 can also inserted by putting it onto a flat surface, and putting the capper with the magnet 12 on the cap. It is important that the crown cap 19 is placed flat in the conical opening 15 of the cylinder 4. Following this, the capper is placed on the bottle, Fig. 5 and 7, so that the crown cap 19 comes to the top of the bottle neck 20. At the same time, the body 1 is let to fall onto the bottle. How far down the body 1 will move depends on the shape of the bottle neck, but it will go no lower than the body stopper 3 that moves through the guide 2. The capper stands firm on the bottle now. Capping is performed by holding the body 1 with one hand, and hitting the anvil 6 strong enough with a hard object with the other hand. The closing force is transferred through the anvil 6 to the cylinder 4 which moves downward, at the same time depressing the spring 13, via the depressing pin 14, which, then, depresses the elastic piston 8 toward the bottle.

Depressing of the cylinder 4 and the elastic piston 8 lasts until the depressing pin 14 hits the first, softer, obstacle which is the lower edge of the piston side opening 10. Further depressing makes the depressing pin 14 hit the harder part of the piston which is the elastic piston stopper 11. At the same time, while the piston 8 is pressing the crown cap 19 towards the bottle neck 20, the conical part of the cylinder 5 presses the corrugated part of the cap 19 over the bottle-neck 20 profile. The bottle is thereby capped. After closing the bottle, the depressed spring 13 pushes the depressing pin 14, pushing the cylinder 4 up and the elastic piston 8 down, this signalling that the capping is completed. The anvil 6 and the elastic piston 8, Fig. 8,10 and 11, are made of a softer material, e. g. rubber. In the bottom end of the elastic piston 8, there is fixed the magnet 12. The elasticity of the piston, the anvil and the spring enables "soft'and safe capping of the bottle, with no danger of breaking the bottle.

Bottle capping can also be performed by a sharper hitting or pressing with palm on the pusher 7, Fig. 4, previously placed on the anvil 6. Further capping procedure is the same as described above.

The capper is designed to enable capping of bottles of all shapes. This is enabled by the body 1 with the guide 2 and the body stopper 3.

The conical part of the cylinder 5 at the lower end of the cylinder 4 enables use of the capper with crown caps of various shapes and makes, including already used caps.

If the body 4 is made of softer material, e. g. plastics, the conical opening of the cylinder 5 is to be inserted a hard insert 21, as shown in Fig. 3.

7. INVENTION APPLICATION The crown capper is very handy for households and and businesses that want to keep smaller quantities of liquids, especially wine, in well closed bottles.

The capper is easy to handle, small and takes little space. It requires no maintenance and malfunctions are rare. The elastic piston and the cone at the end of the cylinder enable easy closing of bottles, with no danger of breaking them.

The capper can be produced both in small manufactures and in factories, of materials available in the market.
