Description

  The present invention relates to an inner bag for quantification of a pressurized beverage bottle, and relates to a pressure container that prevents an overpressure state of a pressure vessel and facilitates cleaning and the like.

When carbonated water is produced at a restaurant or at home, products such as soda siphon are present inside and outside, and carbon dioxide gas is injected under pressure into a liquid such as water. A simple carbonated water production apparatus uses a small carbon dioxide container called a mini gas cartridge. In addition, in Europe, for example in Europe, pressurized beverage bottles called cream whippers, espumas, etc. are widely used in order to add dairy products such as cream in a whipped form to be added to beverages such as dishes, cocktails, and coffee. However, in Japan, nitrous oxide gas (N ₂ O), which is a pressurized gas, has not been approved by the Ministry of Health, Labor and Welfare as a food additive, and the use of alternative gas is being studied.

Espuma is a creamy foam dish that has been used in high-end cuisines abroad, such as Spain, and has been introduced to Japan, and has begun to be used in all kinds of foods and dishes such as dishes, cocktails, coffee, and Western confectionery.
The present invention is suitable for such a field, and uses carbon dioxide (CO ₂ ) other than nitrous oxide gas to ensure safety and to clean the inner surface of the bottle when reusing and problems in terms of hygiene. Etc. are solved.

  Gas pressurizing bottles such as soda siphons and sprayers enclose carbon dioxide in a small gas cartridge as a pressure source for extrusion into a bottle of about 1 liter containing liquid. In the case of water and carbon dioxide, soda water can be produced by shaking.

  When injecting gas, if the amount of liquid in the bottle is large and full, the gas space in the bottle decreases. If the vapor pressure of the gas cartridge is about 6 MPa at room temperature and the gas space in the bottle is small, not only does the pressure exceed 1 MPa, which is a legal restriction, but the bottle has a risk of bursting.

  Therefore, there is a method of providing a relief valve or keeping the liquid level constant as disclosed in Japanese Utility Model Publication Nos. 50-2571 and 62-32608. In the case of the liquid level method, a cylinder called “sleeve” (“cylinder part 27” in the former and “level 6” in the latter is applicable) is inserted in the bottle in advance, and is more than the lower end surface of the sleeve. A gas space is secured in the bottle to prevent liquids such as water from entering.

  In other cases, the user puts an appropriate amount with a measuring cup or the like, or a scale or the like is displayed on the inner surface of the bottle, and the user injects while visually checking.

Japanese Utility Model Publication No. 50-2571 Japanese Utility Model Publication No. 62-32608

  With the advent of soda siphons, it is now possible to easily produce many variations of beverages at home. In the case of soda water, it is only necessary to inject carbon dioxide gas from a small gas cartridge into a bottle of about 1 liter containing water and shake it.

  Dissolution of the gas into the liquid proceeds as the temperature decreases, the pressure increases, and the contact area increases. On the other hand, as the pressure increases, the pressure resistance of the bottle, the safety of the lid structure, and the like become more problematic, and it must be 1 MPa or less also from legal regulations.

  Therefore, in the conventional soda siphon, if the liquid is put in the bottle too much, the gas space is reduced and the pressure of the gas to be injected is reached (for example, in the case of CO2, 20 is 6 MPa).

  In the case of the sleeve type, if the liquid is inadvertently injected first into the bottle and then the sleeve is inserted, or the bottle is tilted when injecting the liquid with the sleeve inserted first, the specified space Cannot be secured.

  In addition to soda siphons, new drinks and foods that are filled with dairy products or alcohol in a bottle called a cream hopper and pressurized with nitrous oxide gas are attracting attention. However, in Japan, nitrous oxide gas is not approved as a food additive, and other gases need to be used. In this case as well as soda water (carbonated water), there is a problem in safety unless the amount of liquid inside is determined, and measures to maintain an appropriate space are required. Furthermore, when creams and the like are used in a bottle, cleaning is very troublesome because of high viscosity, and cleaning is likely to be incomplete.

  Accordingly, the present invention provides an inner bag for quantitative determination of a pressurized beverage bottle that can produce foamed espuma using carbon dioxide, can prevent the bottle from becoming over-pressure, and can be easily cleaned. With the goal.

  An inner bag for quantitative determination of a pressurized beverage bottle according to the present invention has a ring body part that forms an entrance and a main part made of an elastic material following the ring body part. The fixed volume is smaller than the inner volume of the bottle body. The ring portion is supported by the opening of the main body, and the main portion is accommodated in the main body. The main portion does not expand with the weight of the filled quantitative material, but expands when the gas pressure is applied to the weight and comes into close contact with the inner wall surface of the main body. Put out.

  The timing of filling the inner bag with the quantitative material is selected according to the rigidity of the ring body. In other words, if the ring body part is not deformed at all after being filled with the quantitative material and is suspended, it can be carried even if it is deformed. It may be inserted into the main body. If the annular body is deformed and cannot be carried, the inner bag is first inserted into the main body of the bottle, and then the inner bag is filled with a quantitative material.

  The fixed volume may be the total volume including the main part and the ring part, but may be limited to the main part excluding the space part formed by the ring part. As a whole, there is a risk of overflow due to vibration in the case of pre-filling, regardless of post-filling. Limiting to the main part is preferable because the risk is eliminated. Although the boundary between the main part and the ring part can be judged to some extent by visual observation, it is better to put a mark such as a boundary line just in case.

  The main part has elasticity. This elasticity prevents the fixed volume from expanding due to the weight of the quantitative material filled in the main part. This is because if the liquid expands in this state, the fixed volume increases. When the main part is accommodated in the main body of the bottle and is filled with the quantitative material, when the gas pressure is applied, the main part is deformed to expand the quantitative volume, and the outer surface comes into pressure contact with the inner wall surface of the bottle main body. This pressure contact may be against the entire inner wall surface of the main body, or may be a part thereof. Due to this expansion of the main part, a pressure adjusting space part appears in the main part. The space portion provided by the ring body portion also cooperates with this space portion.

The main portion may continue on one surface side of the ring body portion so as to surround the inner peripheral edge of the entrance / exit.
In this case, since one end of the main part opens in substantially the same shape as the entrance / exit, filling of the quantitative material is facilitated.

The quantitative volume may be specified for quantitative determination in a state before filling the quantitative material.
In this case, the quantitative material can be quantified by simply filling the quantitative volume into the quantitative material.

The ring part and the main part may be made of a material that does not adversely affect food.
In this case, it can be used for food and a wide application is secured.

The material may be polyethylene.
In this case, it is elastic and hygienic.

The annular part may be an annular part, and the main part may be an annular part at a continuous contact point with the annular part, and may be a flat part from the middle.
In this case, since the opening of the bottle main body is generally round, the main part can be accommodated in the main body by placing the ring body in this opening, and the opening of the main part and the opening of the main body coincide with each other. Can be done.

The main portion may have a town formed on the side surface.
In this case, when the metering material is filled in the main part, the main part spreads in the town and accommodates the metering material, so the material of the main part itself is not stretched and a predetermined internal volume for quantification is secured. it can.

  The inner bag for quantification of a pressurized beverage bottle according to the present invention does not expand due to the weight of the quantification material for quantification filling, so there is no risk of overfilling, and it expands when gas pressure is added to the weight. Since the space for adjusting the pressure appears while being in close contact with the inner wall surface of the main body, the risk of rupture of the bottle due to a sudden pressure increase can be eliminated.

  According to claim 2, since the main part continues from the one surface side to the ring body part and surrounds the inner peripheral edge of the entrance / exit, one end of the main part is opened in substantially the same shape as the entrance / exit In addition, the quantitative material can be easily filled.

  According to the third aspect, since the quantitative volume is specified for quantitative determination in a state before filling the quantitative material, the quantitative material can be quantified by simply filling the quantitative volume into the quantitative material. .

  According to the fourth aspect, since the ring body portion and the main portion are made of a material that does not adversely affect food, it can be used for food and a wide application is ensured.

  According to the fifth aspect, since the material is polyethylene, it is elastic and hygienic.

  According to the sixth aspect, the annular part is an annular part, and the main part is an annular part at a continuous contact point with the annular part, and is a flat part from the middle. In combination with the roundness of the part, the main part can be accommodated in the main body by placing the ring body in the opening, and the entrance / exit of the main part matches the opening of the main body, so that the quantitative material can be easily filled.

  According to claim 7, since the main part is formed with a town on the side surface, when the quantitative material is filled in the main part, the main part spreads in the town part to accommodate the quantitative material, and the material of the main part A predetermined internal volume for quantitative determination can be secured without expanding itself.

  FIG. 1 is a front view of a specific example of an inner bag for determination of a pressurized beverage bottle according to the present invention by cutting the right half, FIG. 2 is a plan view, and FIG. 3 is a right side view of FIG. Shown with half cut off.

  4 and 5 show a state in which the quantitative inner bag 1 is used for the bottle 2. FIG. 4 shows the state in which the main body 21 and the cap 22 of the bottle 2 are removed and both are shown in cross-section, and the quantitative inner bag 1 is inserted into the main body 21 and filled with the quantitative material M. The right half of is cut and shown. FIG. 5 shows a state in which the cap 22 is attached to the main body 21 of FIG. 4 and the gas pressure from the gas cartridge 26 is introduced into the main portion 13, the surface of the quantitative material M is pushed down, and the main portion 13 is Close to 30, a space portion S for pressure adjustment appears above the main portion 13.

  1 is an inner bag for determination, and 2 is a bottle. This inner bag 1 for fixed quantity has the ring part 12 which forms the entrance / exit 11, and the main part 13 made from an elastic material following this ring part 12. FIG.

  Since the bottle 2 is not a main part of the present invention, only a brief description will be given. In the illustrated case, the bottle 2 has a main body 21 and a cap 22. The cap 22 can be screwed onto a screw 24 on the outer periphery of the opening 23 of the main body 21, and is provided with a nozzle 25 for discharging the quantitative material M and a mounting portion 27 for a cartridge 26 filled with pressurized gas. The attachment portion 27 includes an opening mechanism 28 (for example, a pointed needle). The nozzle 25 is provided with an opening / closing valve 29. Reference numeral 30 denotes an inner wall surface of the bottle 3.

  The bottle 2 is used in a state where a predetermined gas pressure is introduced into the quantitative material M or dissolved. If the bottle 2 is tilted and the on-off valve 29 is opened, the quantitative material M flows out through the nozzle 25 under its own weight or with its own weight and internal pressure.

  In the case of a type of bottle that is extracted while standing upright on a table, it is preferable to use a siphon type. This adds a siphon tube to the cap configuration. The configuration is the same as that of a normal sprayer. The gas pressure in the gas cartridge 26 is released to the outside together with the quantitative material M from the nozzle 25 through the siphon tube by opening the on-off valve 29.

  The fixed volume C1 is smaller than the internal volume C2 of the main body 21 of the bottle 2. In the inner bag 1 for quantitative determination, the ring body 12 is supported on the end face of the opening 23 of the main body 21 of the bottle 2, and the main portion 13 is accommodated in the main body 21. The main portion 13 does not expand the fixed volume C1 due to the weight of the filled quantitative material M. When the gas pressure is applied to this weight, the main portion 13 expands and comes into close contact with the inner wall surface 30 of the main body 21 and also adjusts the pressure. S appears.

  Even if the main body 13 is suspended by holding the ring body portion 12 of the inner bag 1 in a state in which the quantitative material M is filled in the inner bag 1, the annular body portion 12 is rigid to the extent that the quantitative material M does not spill. In this case, the filling of the quantitative material M into the inner bag 1 may be before or after the inner bag 1 is set in the bottle 2. When the rigidity of the ring body 12 is small and the inner bag 1 is filled with the quantitative material M and cannot be carried, the inner bag 1 is first inserted into the main body 21 of the bottle 2 and later this inner bag 1 Is filled with a quantitative material M.

  The fixed volume C1 may be the entire volume including the main part 13 and the ring part 12, but may be limited to the main part 13 excluding the ring part 12. As a whole, there is a risk of overflow due to vibration in the case of pre-filling, regardless of post-filling. Limiting to the main part 13 is preferable because the risk is eliminated. Although the boundary between the main portion 13 and the ring body portion 12 can be determined to some extent by visual observation, it is preferable to attach a mark such as a boundary line just in case.

  The main part 13 has elasticity. This elasticity is set such that the quantitative volume C1 does not expand with the weight of the quantitative material M filled in the main portion 13. If it expands in this state, the fixed volume C1 will increase. When the main portion 13 is accommodated in the main body 21 of the bottle 2 and is filled with the quantitative material M, when the gas pressure is applied, the main portion 13 is deformed to expand the quantitative volume, and the outer surface is the inner surface of the main body 21. Press contact with the wall 30. This pressure contact may be the entire surface of the inner wall surface 30 or a part thereof. Due to this expansion of the main portion 13, a pressure adjusting space portion S appears in the main portion 13. The space portion S also cooperates with the space portion of the annular portion. This space portion S prevents a sudden rise in pressure inside the bottle 2 and eliminates the danger of bottle rupture.

  If the bottle 2 is tilted and the on-off valve 29 is opened, the quantitative material M flows out through the nozzle 25. In the case of the siphon type, the on-off valve 29 may be opened while the bottle 2 is upright.

The main portion 13 continues on the one surface side of the annular body portion 12 so as to surround the inner peripheral edge of the doorway 11.
If it carries out like this, since the end of the main part 13 will open in the substantially same shape as the entrance / exit 11, the filling of a fixed quantity material will become easy.

The quantitative volume C1 is specified for quantitative determination in the state before filling the quantitative material M.
In this way, the quantitative material M can be quantified by simply filling the quantitative volume C1 with the quantitative material M.

The ring body portion 12 and the main portion 13 are made of a material that does not adversely affect food.
If it carries out like this, it can be used for foodstuffs and a wide use will be ensured.

The material is polyethylene.
In this way, it is elastic and hygienic.

The annular part 12 is an annular part 12 ′, and the main part 13 is an annular part 13 ′ at a continuous contact with the annular part 12, and is a flat part 13 ″ from the middle.
In this way, since the opening 23 of the main body 21 of the bottle 2 is generally round, the main body 13 can be accommodated in the main body 21 by placing the ring body portion 12 in the opening 23, and the entrance 11 and the main body 21 of the main section 13 can be accommodated. Since the opening 23 matches, the quantitative material M can be easily filled.

The main portion 13 has a town 14 formed on the side surface.
In this way, when the quantitative material M is filled in the main part 13, the main part 13 spreads in the portion of the town 14 and accommodates the quantitative material M. Therefore, the material itself of the main part 13 does not expand, and the predetermined amount for quantitative measurement is obtained. Can be secured.
