Description

The invention relates to a container with a sliding lid for storing and dispensing liquids, in particular wine. The container comprises a cylindrical body with a bottom and an open mouth, in which a lid abuts from above.

BACKGROUND OF THE INVENTION

L (£ Containers and containers such as tanks, barrels and barrels serve for the storage and storage of liquids and beverages, especially wine.

Smaller barrels, barrels and demijohns are used to store smaller quantities of liquids and beverages, especially wine.

Glass bottles and demijohns are used for archiving beverages, especially wine.

Metal materials such as aluminum, stainless steel, steel or plastics are used for the storage, transport and packaging of beverages of all kinds. In contact with beverages such as beer, lemonade, soft drinks, wines, juices, syrups, milk, etc. leaching of metals or plastics into these fluids may occur. After ingestion, undesirable effects on the human body or taste changes may occur, eg during long-term storage.

2 (1 Plastic material is not suitable for many kinds of beverages for long-term use and storage. A big disadvantage is the necessity of constant tightness check and eventually constant inflating of the inner tube, which has to be replaced after some time.

For the storage of smaller quantities of liquids, especially wine, up to approx.

glass bottles of about 1 liter, glass carboys or barrels, wooden barrels - BARIK, small stainless steel tanks with a floating lid,

- smaller plastic barrels with a floating lid, eg sealed with an inflatable membrane and plastic containers or plastic bellows.

- yAůiip ´W CZ PV 1993-1203 proposes to use glass drums for transporting and storing beverages, consisting of a cylindrical body and fitted with a bandage of 3 mesh and sprayed outside of plastic to protect them against impact. It is preferable to use glass laminated several times, tempered several times and in the quality of DURIT® glasses. This

The solution uses glass as an inert material for beverages. The disadvantage of this solution will probably be relatively expensive and complicated production.

Containers with a floating lid are known and manufactured. The body and the lid are either made of stainless steel _; or plastic. The container body is generally cylindrical with a 5 circular bottom and a cylindrical wall. The container body is provided with a circular, substantially planar and planar lid, with an opening for filling. The seal between the container body and the lid can be solved with an inflatable rubber tube, which is continuously inflated as required to achieve permanent tightness. A fluid removal valve is located above the bottom of the container body.

The advantage of this solution is that the liquid in the container does not come into direct contact with the air, i.e. it is not necessary to transfer it into smaller containers in case of liquid loss. The container is usually designed as a large volume, eg a volume of 100 liters or more, so it can stand in one place. Another advantage is the unbreakability of the stainless material. The floating lid sinks inside the cylindrical body when the liquid is removed, along with the liquid level after the air cushion has been drained.

US 8 _t 333 302 B2 discloses a wine dispenser. The dispenser consists of a cylindrical body with a bottom and an open mouth for storing and dispensing liquid, especially wine. The body is closed vertically at the top by a reversible sliding lid, in a vertical U-shaped cross-section. The lid has a planar circular bottom and a cylindrical wall for abutting the inner cylindrical wall 20 of the container body. The floating lid includes a filling and scoop opening which is closed by a plug. The lid may also be provided with a handle from above. The container body is provided at its lower part with an outlet valve for withdrawing liquid from the container. The bottom of the container is provided with depressions for the deposition of unwanted tartar. The moving floating lid is preferably made of glass. If the cylindrical body is made of 23 glass, it is stated that the wine can be stored under the same conditions as in bottles.

The advantage of the solution is simple handling thanks to the handle in the lid and the drain valve at the bottom of the container. The floating lid decreases by its own weight after draining the liquid through the valve.

Friction problems between the cylindrical body of the container and the moving lid can be overcome by using stainless steel material, but problems such as sticking the cylindrical container to the lid contact surface due to corrosion may occur. One of the causes of this phenomenon is the effect of a “local electric cell”, ie the liquid may be contaminated with metal ions. eg Ni ²⁺ , Cr ³⁺ or Cr ⁶⁺ .

If the lid is made of glass, and the body is either made of stainless steel or glass, it is not secured between

2 'with a cylindrical body and a lid no circumferential sealing, so that air can penetrate inside the body and the liquid can be destroyed.

Especially with some liquids, especially guilt, it is essential to ensure that all air escapes above the surface in order to maintain their quality.

X The most common way for winemakers to prevent oxidation of wine levels in practical conditions is to use small containers - mostly glass bottles. Materials other than glass, such as plastics and paper boxes, are possible, but their advantage is perhaps only to reduce the cost of packaging. Glass bottles are manufactured in dimensions and content for small consumers. The volumes are, for example, 0.3 Irtraj, 0.5 0.7 1.5 µFyf and 5 liters. Assuming

It is believed that the customer purchases a package whose contents, when opened, will be consumed and thus prevent possible oxidation of the wine.

The situation is different for wine producers and winemakers. Of course, they face possible oxidation of the wine mainly by bottling. The situation of medium and unspecified consumption is being solved by vintners in practice. They are usually bottled in large-volume glass containers or demijohns. During the tasting and especially in the consumption of wine in their wine cellars, they use traditional wine tasting glasses to collect the wine and pour it into the drinking glass. But after consuming a certain, relatively small amount of guilt, a large surface contact of the wine level with the air opens over the wine in the demijohn, and the risk of oxidation is very high. At the same time, the air exposure time required for oxidation, that is to say, to degrade the wine, decreases 2ΰ with increasing wine surface area and with increasing air volume above the wine. The permanent capping of the demijohn has only a limited positive effect. That is why the winemaker always adds wine to the demijohns after the “action” so that the demijohns are always full with a minimum volume of air above the wine level in the demijohn's neck, similar to the neck of a glass bottle. It is a laborious and sometimes impossible solution. If the given type of wine comes to make-up and the winemaker, $ 3 if he does not want to harm the wine in the demijohn by oxidation, he must pour the rest of the wine into bottles.

SUMMARY OF THE INVENTION

These drawbacks are eliminated or substantially reduced in a container with a sliding lid for storing and dispensing liquids, especially wine, of the present invention. The essence of this invention is that the cylindrical container and the lid abutting on the common vertical axis have a rotational shape with respect to the common vertical axis; the lid is reversibly slidable vertically along the inner walls of the container body; the sliding lid is hollow and comprises a vertical upper narrow tube located in the vertical axis of the lid forming a central opening for filling and withdrawal of liquid, followed by a conical downwardly extending concave portion extending into the vertical lower ring. A peripheral seal for sealing between the lower ring j is mounted on the lower ring of the sliding cover

the sliding lid and the inner wall of the container body and for separating the liquid and air. The central opening of the sliding lid is tightly closed by a plug.

The main advantage of the present invention is the safe storage and dosing of liquid in the sliding lid container of the present invention with maximum protection against liquid oxidation and air access while ensuring health safety. The container with sliding lid is easy to purchase, easy to operate and very easy to clean. The rotating shape of the container and the sliding lid ensures their stability. The sliding lid is designed to reciprocate vertically along the inner walls of the container body, allowing close contact therebetween, thereby separating the liquid from the external atmosphere. The hollow narrow tube of the sliding lid also serves as a central opening for filling the container with the sliding lid with liquid. The central opening is closable with a sealing plug. The tapered part of the sliding lid ensures continuity between the narrow tube of the sliding lid and the lower ring of the sliding lid, which must fit snugly against the inner walls of the container body. This secure seal between the container body and the adjacent sliding lid 14 is further secured by a peripheral seal on the ring.

Preferably, the container and / or sliding lid is made of at least one of glass, stainless steel and plastic, and the plug is made of at least one of glass, cork or plastic. These materials are selectable according to customer requirements and with respect to the type of liquid in the sliding lid container. The stainless steel container may not have a seal, but it is not visible to the liquid inside the container. Plastic is unsuitable for liquids, especially beverages. Quality cork is suitable for liquids such as drinks, especially wine. The most suitable material for liquids in a sliding lid container is glass which does not introduce heavy metals into liquids such as drinks and wine and is harmless to health.

The sliding cover is provided with a peripheral seal on its surface, which is in contact with the body of the container, i.e. on the outer surface of the lower ring, so that the liquid level is safely separated from the external air atmosphere.

It is highly preferred that the container and / or the sliding lid or plug are made of glass, transparent or opaque, which is toughened, exhibits chemical resistance, is determinative and absorbs UV radiation. The chemical resistance may be in the IV range. class to class I hydrolytic resistance, while IV. class corresponds to chemical resistance against water and acids for utility glass. Transparent glass allows the liquid to be observed in a container with a sliding lid. Opaque glass may be required for high quality wine in order to safely exclude the effects of light. The chemical hydrolytic resistance of the glass 35 provides an inert material for liquid storage and stability. Determined glass prevents heat radiation from entering the liquid in the container with the sliding lid. UV absorbing glass does not let UV radiation from sunlight into the liquid.

| in

The seal mounted on the outer surface of the lower ring of the sliding lid is preferably made of an inert and food-safe material, such as silicone or rubber, ensuring the quality of the liquid in the sliding lid container. The gasket can be glued to the sliding cover. An improvement is provided when the lower ring of the sliding cover is provided on its outside with a circumferential groove in which the circumferential seal is fixed. In case of long-term use, the gasket is easily adhered or replaced.

Furthermore, it is advantageous if the glass sliding lid has a glass stopper which, in its overlapping part above the tube, has, in the horizontal axis direction, a small opening sealed to the interior of the sliding lid and the liquid container with a sealant such as glass rod or potted wax . This solution serves to improve the exhaust of air from the interior above the liquid level in a closed container with a lid.

and

It is also advantageous if the tube allows the insertion of a food tube which serves to drain the liquid into the provided container when the sliding lid is compressed. The use of a food hose meets the requirement for food safety and is fully hygienic and safe to handle with liquid.

For ease of guidance of the sliding lid into the container body, it is advantageous for the container body at its open end to be extended into a conical mouth for easy opening of the lid into the container. The container body may be provided with a drain hole in the lower half for possible adjustable liquid discharge.

The container with a sliding glass lid, stopper and seal of the present invention is a versatile container for use in wine cellars.

DETAILED DESCRIPTION OF THE INVENTION

In a particular exemplary and non-limiting embodiment, the container 1 and the sliding lid 5 abutting thereon are shown in Figures 1 to 9.

Figures 1 and 2 show a cylindrical vessel 1 for storing wine, eg for storing 5 to 70 liters of wine. The size of the container 1 with the sliding lid 5, its content, height and diameter are chosen to meet the requirements of the user. The container 1 is shown in a vertical section in Fig. 1 and in a top view in Fig. 2. The container 1 consists of a vertical cylindrical body 2 of a cylindrical body 2 with a circular bottom 3, the cylindrical body 2 being shaped at its open end into a conical widening mouth 4.

1Ó. FIGS. 3 and 4 show a circular sliding lid 5 in vertical section and FIG. 4 from above.

According to Figures 1 to 4, both the container 7 and the sliding lid 5 have a rotational shape in the vertical axis 6 to the height of the container 1, i.e. in any horizontal axis 7 perpendicular to the vertical axis 6, the cross-section of the container 1 and the sliding lid 5 is circular. Another cross-section of the body 2 of the container 1 a (posuv of the sliding lid 5, eg oval, ellipsoidal, etc.) may be used, although these shapes will be more difficult to manufacture, but may provide some interesting design.

The sliding lid 5 in a particular exemplary embodiment consists of an upper narrower vertical hollow tube 8, adjoining the continuously widening conical concave portion 9, passing into a shorter cylindrical vertical lower ring 10. The outer surface of the container body 2 and the concave part 9 or the tube 8 of the sliding lid 5 can optionally be decorated e.g. vine leaves, lettering, etc., by a suitable technique, eg fine sanding, painting, etc.

The container 1 and the sliding lid 5 are made of transparent glass with good mechanical resistance to impact and damage, and with good chemical resistance to 15. water and acids, IV. to II. chemical resistance class. E.g. one of the requirements for utility glass is chemical resistance IV. chemical hydrolytic resistance class. In the case of SIMAX® glass, the glass has a chemical resistance class. It is very suitable to use extra glass, ie heat-resistant, as well as glass with high UV absorption, which is impermeable to sunlight. These properties of glass help to maintain high stable wine quality for a long time. Semi-transparent glass, eg amber glass, or opaque, opaque glass may also be used. The advantage of the transparent or semi-transparent glass of the container 1 and of the sliding lid 5 of transparent glass is the possibility of visual inspection of the wine in the container. It is also possible, upon request of the customer 5K, that the container 1 and / or the sliding lid 5 are made of a material other than glass, eg stainless steel.

The body 2 of the container 1 can be provided in its lower half, preferably above the bottom 3, with a valve (not shown) for a possible controllable discharge of the wine.

The hollow tube 8 of the sliding lid 5 serves as the open mouth of the central opening 11X by which the wine is poured, topped up and withdrawn into the container 1 with the lid 5. The central opening 11 is provided with a closable stopper 12 at its top. If the stopper 12 is glass, it may be ground on the outer surface facing the inner ground surface of the throat of the sliding cap tube 8. The plug 12 may not be made of glass but cork or suitable wood or rigid plastic. The plug 12, when it comes into contact with the central opening 11, can be provided in its overlapping part above the tube 8 with a small opening (not shown) in the direction of the horizontal axis 7 which serves to exhaust air completely from the interior of the container 1 with the sliding lid 5. this small hole is perfectly sealed, eg by glass rod, wax casting etc.

The sliding lid 5 is provided with an annular peripheral seal on its surface, which is in contact with the lid body 2 on the container body 1, i.e. on the outer surface of the lower ring 10.

13, in a vertical cross-section eg circular. The seal 13 is made of an inert and food-safe material such as, for example, silicone or rubber. In the exemplary embodiment of FIG. 8 and of detail A in FIG. 9, the seal 13 is provided with an annular seal 40 disposed on the outer surface of the lower ring 10 of the sliding lid 5 and abutting the inner surface of the container body 2. In this embodiment an annular seal 12 which is hygienically and sanitaryly safe. Multiple seals 13 located one above the other may also be used. The seal 13 can be securely glued to the lower ring 10 of the sliding cover 5. Alternatively, a groove 14 (not shown) is formed on the outer surface of the lower ring 10 of the sliding cover 5, into which the seal 13 is fastened.

5, 6 and 7, the container 1 filled with wine and a closely fitting sliding lid 5 with a plug 12 are shown in vertical section. The sliding lid 5 is reciprocally movable in vertical direction on the inner walls of the container body 2, from its upper position XQ shown in Fig. 5 up to its lower position shown in Fig. 7.

In Fig. 5 the sliding lid 5 is at the top dead center after the container 1 has been filled with wine. Wine is poured onto the containers 1 through the central opening 11 of the sliding lid 5 with the seal 13 mounted on the lower ring 10 of the lid 5. After filling the container 1 with wine, the central opening 11 is closed with a stopper 12.

The contact space between the inner surface of the container body 2 and the adjacent outer surface of the lower ring 10 of the sliding lid 5 is sealed by a gasket 13.

FIG. 6 shows in vertical section the container 7 with the sliding lid 5 closed by the plug 12 in the middle position, after the wine has been removed from the container 1. The wine is picked up from the central opening 11 of the sliding lid 5 after removing the plug 12, e.g. a food hose that is not harmful to health. After the wine has been collected, the sliding lid 5 is manually pushed down towards the wine level, the air below the sliding lid 5 being forced out and exiting through the central opening 11 as long as the level of the wine rises to the upper mouth of the tube 8 of the sliding lid 5. The air above the sliding lid 5 and the level of wine in the container 1 are separated by a seal 13 between the container 1 and the sliding lid.

5.

FIG. 6 shows a vertical section of the container 7 with the sliding lid 5 in the lower position, at the bottom dead center. The sliding lid 5 bears with its lower ring 10 on the bottom 3 of the container body 2. There is wine between the interior of the sliding lid 5 and the bottom 3 of the container body 2. To fill the container 7 with wine, it is now necessary to remove the plug 12 from the central opening 11 of the sliding lid 5, fill the container with wine through the central opening 11 to the upper mouth of the tube 8 of the sliding lid. The cover 5 is then again in the upper position shown in FIG. 5.
