Description

Container with sliding lid for storing and dosing liquids, especially wines

Technical field

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. Optionally, the container body is provided with an outlet opening in the lower half.

BACKGROUND OF THE INVENTION

For the storage and storage of liquids and beverages, especially wine, there are large-scale tanks or containers such as tanks, barrels and barrels.

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 to store, transport and package 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.

Plastic material is not suitable for many types of beverages for long-term use and storage. A major disadvantage is the necessity of constant leak checking and, possibly, a substantially continuous blowing of the sealing tube, which has to be replaced over time. The stainless steel container is relatively expensive.

For the storage of smaller quantities of liquids, especially wine, with a capacity of up to approximately 200 liters:

glass bottles of approx. 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 packaging or plastic bellows.

The document 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 tightening mesh and sprayed outside of plastic to protect them against impact. It is preferable to use glass which has been laminated several times, tempered several times and is of DURIT ^W glass quality. This 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 lid are made of either stainless steel or plastic. The container body typically has the shape of a cylinder with a 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 released.

US 8333 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 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 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.

The friction problems between the cylindrical container body and the moving lid can be overcome by the use of stainless steel. However, problems such as the bonding of the cylindrical container to the lid contacting surface due to corrosion may arise. If both the container and the floating lid are made of metal, corrosion of the material occurs even when stainless steel is used. One of the causes of this phenomenon is the effect of a “local electric cell”, ie the liquid may be contaminated with metal ions. When using stainless materials in this case, the liquid may be devalued mainly by undesirable cations such as Ni ²⁺ , Cr ³⁺ or Cr ⁶⁺ . If the lid is made of glass, and the body is either stainless steel or glass, there is no circumferential seal between the cylindrical body and the lid, so that air can penetrate inside the body and the liquid can be destroyed.

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

The most common way for wine growers to prevent oxidation of wine levels in practical conditions is to use small containers - mostly glass bottles. Materials other than glass are possible, such as plastics and paper boxes, but their advantage is perhaps only a reduction in packaging prices. Glass bottles are manufactured in dimensions and content for small consumers. The volumes are, for example, 0.3 liters; 0.5 liters; 0.7 liters; 1 liter; 1.5 liter; 2 liters; and 5 liters. It is assumed that the customer purchases such a package, the contents of which they consume after opening and thus prevent possible degradation of wine by oxidation.

For wine producers, the situation is somewhat different. Of course, they face possible oxidation of 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 tasting and especially in the consumption of wine in their wine cellars, they traditionally use glass tasters to collect the wine and pour it into the drinking glass. But after consuming a certain relatively small amount of wine, 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, i.e. the degradation of wine, decreases with increasing surface area of the wine 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 a given type of wine arrives for replenishment and the winemaker does not want to hurt the wine in the demijohn by oxidation, the rest of the wine must be poured into bottles.

The essence of the technical solution

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

-2EN 26175 Ul

The main advantage of this technical solution is the safe storage and dosing of liquid in a container with a sliding lid according to this technical solution 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 wall 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 can be closed with a sealing plug. The tapered portion 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 wall of the container body. This secure seal between the container body and the adjacent sliding lid is further secured by a circumferential 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 is 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 provides an inert material for the storage and stability of the liquid. 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.

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 lid 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.

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

It is also advantageous if the tube allows the insertion of a food tube which serves to drain the liquid into the provided container while pressing the sliding lid. 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 preferred that the container body at its open end extends into a conical mouth for easy guide of the lid into the container.

A container with a sliding glass lid, a stopper and a gasket according to this invention is a universal container for use in wine cellars.

Technical solution

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.

1 and 2 show a cylindrical wine storage container 1, e.g. for storing 5 to 70 liters of wine. The size of the container 1 with the sliding lid 5, its contents, 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 with a circular bottom 3, the cylindrical body 2 being shaped at its open end into a conical widening mouth 4.

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

According to FIGS. 1 to 4, the container 1 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 is movable. Other cross-sections of the container body 2 and the sliding lid 5, such as oval, ellipsoidal, etc., may also 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, extending 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 11 and the sliding lid 5 are made of transparent glass with good mechanical resistance to impact and damage, and with good chemical resistance to 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 ¹⁸ glass, the glass has a chemical resistance class I. The use of additional glass, ie resistant to heat radiation, as well as glass with high UV absorption, impermeable to sunlight, is very suitable. 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 i and of the sliding lid 5 of transparent glass is the possibility of visual inspection of the wine in the container i. The glass thickness of the container i and of the sliding lid 5 is chosen according to the size of the container i. It is also possible, at the customer's request, that the container I and / or the sliding lid 5 are made of a material other than glass, e.g. stainless steel.

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

The hollow tube 8 of the sliding lid 5 serves as an open mouth of the central opening JT by means of which the wine is poured, topped up and removed into the container I with the lid 5. The central opening 11 is provided with a closable stopper 12 in its upper part. If the stopper 12 is glass, it may be ground on the outer surface facing the inner ground surface of the throat of the tube 8 of the sliding lid 5. The stopper 12 need 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 with a small opening (not shown) in the direction of the horizontal axis 7 in its overlapping part above the tube 8, which serves to exhaust air completely from the interior of the container with the sliding lid 5. this small hole perfectly seals, eg glass rod, wax casting etc.

The sliding lid 5 is provided with an annular peripheral seal 13 in a vertical cross-section, e.g. circular, in contact with the lid 2 of the container 1, i.e. on the outer surface of the lower ring 10, on its surface. 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 13 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. 13, which is hygienically and sanitary safe. Multiple seals 13 located one above the other may also be used. The seal 13 can be securely adhered to the lower ring 10 of the sliding cover 5. Another solution is also possible, wherein a groove 14 (not shown) is formed on the outer surface of the lower ring 10 of the sliding cover 5, in which the seal 13 is fixed.

FIGS. 5, 6 and 7 show, in vertical section, a container filled with wine and a closely fitting sliding lid 5 with a plug 12. The sliding lid 5 is reciprocatingly movable vertically on the inner wall of the container body 2, from its upper the position shown in FIG. 5 up to its lower position as shown in FIG. 7.

In Fig. 5, the sliding lid 5 is at the top dead center after the container has been filled with wine. The 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 and the wine, the central opening 11 is closed with a stopper 12. fault.

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 I with the sliding lid 5 closed by the plug 12 in the middle position, after the wine has been taken from the container I. 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 under the sliding lid 5 being forced out and exiting through the central opening 11 as long as the wine level rises to the upper mouth of the sliding lid tube 8. Then The air above the sliding lid 5 and the level of wine in the container 11 are separated by a seal 13 between the container 1 and the sliding lid 5.

FIG. 7 shows a vertical section of the container 1 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. Between the inner space of the sliding lid 5 and the bottom 3 of the container body 2 is wine. To fill the container 1 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.

Industrial applicability

The solution is designed for medium producers and medium consumers of wine and other liquids with a container size of up to about 100 liters. The solution is intended wherever the lowest possible influence of air above the level of stored liquid is preferred.
