Description

Description: [0001] The invention relates to a drinking bottle which, according to the preamble of patent claim 1, comprises a volume-enclosing bottle body and a lid which can be mounted on the neck of the bottle and has a carbonating unit.

As is known from the prior art, carbon dioxide can be produced by introducing carbon dioxide into water under overpressure. Carbonated drinks provide a pleasant tingle on the tongue and promote the perception of fine taste differences. Since carbonated drinks are generally very popular, there are many suppliers of carbonated drinks and also providers of equipment with which you can fizzle at home, so stationary, his drinks with carbon dioxide to carbon dioxide an example of a stationary Wassersprudler is the invention US 2015 044 343 A1. This invention consists of a stationary device equipped with a carbon dioxide gas bottle. The carbon dioxide gas is added from the gas bottle directly into a water bottle with water introduced, thereby creating a chemical reaction in the water and carbon dioxide are the starting material and their product is then finally the carbon dioxide. Because of the instability of carbon dioxide, this reaction can only be done under pressure, otherwise the later drink would have a low concentration of carbonic acid.

In addition to the stationary Wassersprudlern there is also the possibility today with mobile Wassersprudlern carbonated drinks produce. The stationary Wassersprudler can today be replaced as needed already by this technique.

These mobile water bubblers are usually connected to the already filled with drinking water bottle and carbonated via a gas inlet pipe, which is connected to the mobile Wassersprudler, carbonated with carbon dioxide from a simple capsule. Examples thereof are the inventions US 005 329 975 A, US 005 531 254 A, GB 2 477 756 A, DE 20 2015 006 881 U1, WO 2015 180 220 A1 and US 2015 0 201 794 A1. Although all of these listed mobile water bubblers look different and have different characteristics, they all have the same operating principle, namely the discharge of carbon dioxide from a small capsule inside the device, which is outside the bottle.

Another common feature connects these inventions also, namely the fact that all equipment must be transported separately and stored. This can lead to inconvenience, since a mobile Wassersprudler compared to the water bottle can be large and therefore takes up a lot of space. In addition, the fumigation is delayed with an external device, because the device must first be unpacked and prepared. These points often lead to the abandonment of the mobile carbon dioxide supply.

The present invention is therefore an object of the invention to provide a simple, compact, metered and space-saving carbonization in a specially designed bottle.

The solution to these problems consists in a bottle with the features listed in the claims 1 to 4.

On the one hand, the invention looks the commercial water bottles of the other Wassersprudleranbieter optically very similar. It also consists of a simple liquid container with a thread, so that the lid can be screwed on, in addition, a drinking tube can still be attached to the lid.

On the other hand, however, the invention differs from the current mobile, stationary Wassersprudlern in the position of Karbonisierungssystems. The Karbonisierungssystem is already built into the bottle from the ground up and therefore requires no additional mobile or stationary, space-consuming devices.

The invention facilitates the transport, since additional devices omitted and everything is packed together. The already installed carbonization unit (27, Fig. 4) makes the fumigation with carbon dioxide faster and more convenient. Furthermore, the invention also makes it possible to maintain carbon dioxide in beverages that have not been sweetened or have already been treated with extract.

In the following an embodiment of the invention will be explained in more detail with reference to the not to scale, schematic drawings.

Embodiment A fundamental part of the drinking bottle is the lid (1, Fig. 1), which can perform a number of tasks. In the first place, the lid (1, Fig. 1) is responsible for ensuring that the liquid container (2, Fig. 4) is sealed, further, the lid (1, Fig. 1) provides a closable drinking opening (3; 1). The drinking opening (3, Fig. 1) can preferably consist of a one-hand operable closure system (4, Fig. 4) with associated drinking tube (5, Fig. 4). The lid (1, Fig. 1) may be provided with a seal (6; Fig. 1) to maintain tightness.

The gassing acts on the drinking opening (3, Fig. 1), which is why a tight closure system (4, Fig. 4) is very important. A solution to this is a closure system (4, Fig. 4) with a locking body (7, Fig. 1), which closes automatically when hitting the pressure from below. Thus, the gas closes itself the way. In order to make this possible, a blocking body (7, Fig. 1) can be connected to the mouthpiece (8, Fig. 1) and be mounted so that it opens at a top-acting force and automatically closes when coming from below. For this purpose, the opening should show a constriction (9; Fig. 1) just before the mouthpiece (8; Fig. 1), the blocking body (7; Fig. 1) should then be below this constriction (9, Fig. 1) and with a rod-shaped body (10, Fig. 1) with the mouthpiece (8, Fig. 1) to be connected. In the ground state, the blocking body (7, Fig. 1) is always in the closed state, this allows a spring (11, Fig. 1), which keeps the mouthpiece (8, Fig. 1) always pushed upwards. However, because in this case there is still the danger that the opening will open by itself, especially during transport, an additional locking device (12, Fig. 2) is mounted on the mouthpiece (8, Fig. 1). This closure safety (12, Fig. 2) prevents inadvertent opening of the drinking opening (3, Fig. 1). In addition, the safety catch (12; Fig. 2) should be rotatable, therefore, the lock securing bodies (13; Fig. 2) are fixed to a rotatable plate (14; Fig. 2). The rotatable plate (14, Fig. 2) lies loosely between the mouthpiece (8, Fig. 1) and its attachment. When closed, the closure securing bodies (13; Fig. 2) are located on the lid surface (15; Fig. 2) and, when drunk, their position over the two openings (16; Fig. 2) on the lid surface (15; Fig. 2), which allow a downward movement. In addition, because of the movements of the mouthpiece (8, Fig. 1), a crushable tube portion (17, Fig. 1) is required [0011] In addition, there is also the ability to compensate for the underpressure and overpressure in the container. For the vacuum compensation, a non-return valve (18, Fig. 5) is installed, which changes its shape when it is suppressed, allowing air to flow into the system from above, and as soon as normal pressure returns, the non-return valve (18, Fig. 5) immediately takes over again their original position, thus preventing the escape of the liquid from the container. Another fitting is the spring loaded (19; Fig. 1) pressure relief valve (20; Fig. 1), whose mission is to eliminate the overpressure after carbonization. The pressure relief valve has a gas discharge opening (21, Fig. 1) on the lower lid side. In addition, the pressure relief valve (20; Fig. 1) has a seal (22; Fig. 1) which, when triggered, ensures that the gas escapes via the gas discharge opening (21; Fig. 1).

The third fitting in the cover (1, Fig. 1) is a safety device, a so-called safety valve (24, Fig. 5). The bottle experiences a pressure of up to 8 bar when fumigated, so it must be designed to withstand at least twice as much. To avoid such a situation with certainty, it requires a safety valve (24, Fig. 5), which engages at a pressure of at most 11 bar. The safety valve (24, Fig. 5) is under constant spring tension (25, Fig. 5) and is thus permanently closed, only when the trigger pressure is reached, the safety valve (24, Fig. 5) opens and frees the container from the pressure.

Another particularity is the gas release (26, Fig. 1), which is located directly next to the mouthpiece (8; Fig. 1). The exact function of the gas release (26, Fig. 1) will be explained in more detail in the following sections.

The upper end forms the mouthpiece (8, Fig. 1) which is ideally equipped with a bite valve (23, Fig. 1). The lower end forms the carbonizing unit (27, Fig. 4), which is connected to the lid (1, Fig. 1). For the lid (1, Fig. 1) and the carbonizing unit (27, Fig. 4), plastic is preferred as the material. The mouthpiece (8, Fig. 1) is preferably made of an elastomeric plastic. The liquid container (2, Fig. 4) may be made of plastic or stainless steel. Metallic materials are preferable to parts that are subject to high loads. These parts include the closure system (4; Fig. 4), pressure relief valve (20; Fig. 1), and the gas release (26; Fig. 1).

In addition, it would be advantageous if the lid (1, Fig. 1) consist of cover part 1 (29, Fig. 1) and cover part 2 (30, Fig. 1), since the production, cleaning and maintenance would be easier. For this purpose, the two cover parts should be joined via screw with a seal.

The heart of the invention is the carbonizing unit (27, Fig. 4) and its associated elements. The carbonizing unit (27, Fig. 4) is connected to the lid (1, Fig. 1). The cover (1, Fig. 1) is strictly connected only to the capsule bearing (31, Fig. 4) in which the carbon dioxide capsule (32, Fig. 4) is located. The capsular bearing shell (28, Fig. 4) connects via a thread (35, Fig. 7) with the capsule bearing (31, Fig. 4) and thus indirectly with the cover (1, Fig. 1). In addition, there is still a seal (36, Fig. 7) at the upper end of the capsule bearing (31, Fig. 4), which seals the connection between the capsular bearing shell (28, Fig. 4) and the capsule bearing.

The innermost unit forms the capsule bearing (31, Fig. 4) with the carbon dioxide capsule (32, Fig. 4). Optically, the capsule bearing (31, Fig. 4) can be considered as a hollow, semi-circular container. The lower part of the capsule bearing (31; Fig. 4) forms a constriction (33; Fig. 3) which approximately corresponds in diameter to the capsule head (45; Fig. 3).

This constriction (33, Fig. 3) provides the capsule with additional stability and seating strength. At the upper end of the capsule bearing (31, Fig. 4) is the cover (34, Fig. 4), which is responsible for holding the carbon dioxide capsule (32; Fig. 4), also lies on the outside of a thread (35; Fig. 7), which allows the connection with the capsular bearing shell (28, Fig. 4). Over the ceiling (34, Fig. 4) is a gap (37, Fig. 4), which allows the adjustment of the actuating body (38, Fig. 4).

The actuator body (38; Fig. 4) is connected to the gas actuator (26; Fig. 1) via a spring-biased connection (39; Fig. 1). Main task of the actuator (38, Fig. 4) is the transmission of the pressure force from the gas trigger (26, Fig. 1). The rod of the actuating body (38, Fig. 4) slides flush between the capsular bearing wall (31, Fig. 7) down to below the constriction (33, Fig. 4) and forms there a circular shape. For reasons of stability, it is also possible to use a plurality of actuating bodies (38, Fig. 4) so that the force is distributed more uniformly.

Due to the high pressure in the carbon dioxide capsule (32; Fig. 4), a large force acts on the blocking body (40; Fig. 3) in the gas valve (41; Fig. 4) so that it can be lifted without much effort a lever system (42; Fig. 1) for the gas release (26; Fig. 1). A one-sided lever would be best suited for this.

The next unit is the capsule bearing shell (28; Fig. 4), which guarantees one for the separation of the capsule bearing (31; Fig. 4) with the drinking liquid and the other for the release of the gas. The capsule bearing shell (28, Fig. 4) consists of a cylinder with small openings (55, Fig. 3) in the bottom, a thread on the upper part, a gas valve (41, Fig. 4) and a check valve (43, Fig. 3) ). The most important, apart from the separation characteristic, is the ability to puncture the carbon dioxide capsule (32, Fig. 4) by means of the gas valve (41, Fig. 4) and to control its flow. Therefore, the gas valve (41; Fig. 4), which is preferably made of stainless steel, has a hollow gas release pin (44; Fig. 3) at the top end which separates the capsule head (45; Fig. 3) of the carbon dioxide capsule (32; 4) during screwing to the capsule bearing (31, Fig. 3) pierces and thus opens. In order for the connection between the carbon dioxide capsule (32; Fig. 4) and the gas valve (41; Fig. 3) to remain tight, there is still a seal (46; Fig. 3) therebetween.

In the interior of the gas valve (41, Fig. 3) sits the spring - loaded (47, Fig. 3) locking body (40, Fig. 3) which is mounted on a pin (48, Fig. 3) with a thickening (49; 3) is connected at the other end. The blocking body (40, Fig. 3) has in the gas valve chamber (5.1, Fig. 3) via a seal (50, Fig. 3), which preferably consists of an elastomer and thus can better enable the seal. A good seal is necessary since the gas valve space (51, Fig. 3) is filled with gas after piercing the capsule. The locking body (40, Fig. 3) should have the smallest possible diameter and further also have a shape that produces a small resistance in the upward movement. For this reason, a spherical lock body (40, Fig. 3) is most suitable.

Further down in the gas valve (41, Fig. 3) are two lever rods (52, Fig. 3) which then convert the downward force of the actuator (38, Fig. 4) into an upward force. This is necessary because the blocking body (40, Fig. 3) in the gas valve (41, Fig. 4) is locked with a downward force. In addition, the additional lever action also reduces the opening force for the blocking body (40, Fig. 3) in the gas valve (41, Fig. 4). So that the lever rods (52, Fig. 3) only rotate in one direction and therefore always remain in this basic state, there are stoppers (53, Fig. 3) over the lever rods (52, Fig. 3).

In order that no drinking liquid penetrates through the outlet holes at the bottom of the capsule-bearing jacket (28, Fig. 4), a non-return flap (43, Fig. 3), which should be made of an elastomer, may be used. The check valve (43, Fig. 3) may be placed directly below the gas valve opening (54, Fig. 3). For all individual parts in the gas valve (41, Fig. 4) a rust-resistant, metallic material is preferable, since high loads are present.

For the carbonization is preferably cold pure drinking water used and presented in the bottle. Next, a new carbon dioxide capsule (32; Fig. 4) is inserted into the capsule bearing (31; Fig. 4) when the already existing carbon dioxide capsule (32; Fig. 4) is empty. Thereafter, the capsule bearing (31, Fig. 4) together with carbon dioxide capsule (32, Fig. 4) with the capsular bearing shell (28, Fig. 4) via a thread (35, Fig. 7) closed and at the same time the carbon dioxide capsule (32; 4). The gas valve space (51, Fig. 3) is now under carbon dioxide pressure. After the lid (1, Fig. 1) has been screwed onto the container, fumigation can take place. For this purpose, the gas release (26, Fig. 1) on the lid (1, Fig. 1) slightly pressed, because this downward force is transmitted to the steep body (38, Fig. 4) and acts down until the lever rods (52 Fig. 3) invert this force upwards. By the upward movement of the lever rods (52, Fig. 3), the blocking body (40, Fig. 3) in the gas valve (41, Fig. 4) is transported upwards and thus forms a passage for the carbon dioxide gas from the capsule (32; 4). The carbon dioxide gas flows immediately after this movement through the non-return flap (43, Fig. 3) and the openings (55, Fig. 3) at the bottom in the drinking liquid. This process takes up to 10 seconds depending on the need for carbon dioxide. Not all of the capsule contents need to be emptied for carbonation, this meterability allows the adjustable gas valve (41, Fig. 4), i. the carbon dioxide capsule (32; Fig. 4) may then continue to remain partially occluded in the capsule bearing (31; Fig. 4). After carbonation has taken place, the contents should be shaken briefly and only when the carbonated drink is stationary, ie when no strong foaming is present, can the pressure relief valve (20, Fig. 1) on the lid (Fig. 1) be actuated. After these steps, carbonation should be guaranteed.
