Description

  The present invention relates to a liquid holding container and a liquid supply apparatus that are filled with wine, liquid chemicals, and the like to be transported and stored.

  It has been a problem in the past that the liquid that is transported and stored after being filled in a bottle is deteriorated with time due to air interposed between the stopper and the liquid when sealed with a cork or a metal stopper. In particular, it has been an important issue for products such as wine and liquid chemicals whose quality deteriorates significantly when oxidized. In order to solve this problem, it is necessary not only to prevent the filled liquid from coming into contact with air, but also to prevent the dispensed volume from being replaced by air during use. As an example, conventionally, a wine server equipped with a hollow body in a bottle has been proposed (see, for example, Patent Document 1). According to this wine server, a volume of air corresponding to the amount dispensed is sent to the hollow body in the bottle, and the hollow body expands to dispense liquid. Therefore, liquid (wine) can be stored and used without being brought into contact with air.

  However, the wine server disclosed in Patent Document 1 has to install a bottle filled with wine upside down, and a series of operations such as holder preparation, bottle setting, storage of the apparatus, etc. are very There was a problem of being complicated. This is because the wine server disclosed in Patent Document 1 has a situation in which the bottle has to be turned upside down.

  Specifically, since the hollow body formed in the shape of a vertically long balloon tends to float upward when air is sent in, when the bottle is upright, as shown in FIG. 15 and FIG. The hollow body 1000 formed by bending at the boundary 1010 with the tube and then making it difficult to send air, or the upper part 1020 of the hollow body easily expands, so that the hollow body 1000 and the inner wall of the bottle are in contact with the upper side of the bottle This is because in some cases, it becomes impossible to pour out the liquid below the contacted position.

  When the bottle is turned upside down, the hollow body floats straight upward, so the above situation is avoided, but even in that case, the problem remains that the liquid cannot be properly poured out when the hollow body expands unevenly. . In any case, setting the bottle upside down was very cumbersome.

  Hereinafter, a liquid holding container and a liquid supply apparatus according to embodiments of the present invention will be described in detail with reference to the drawings. Note that, in each embodiment, the same reference numerals are given to the same functional units, and detailed descriptions of overlapping portions are omitted.

  [Embodiment 1] FIG. 1 is a sectional view showing the shape of a liquid holding container according to Embodiment 1 of the present invention. The liquid holding container 100 mainly includes a container main body 10, a stopper 20, an air supply tube 30, an air bag 40, and an extraction tube 50.

  The container body 10 is a bottle or the like filled with a beverage such as wine or a liquid medicine. The stopper 20 is formed of an elastic body such as rubber, and is fitted to seal the container, and holds an air supply tube 30 and an extraction tube 50 described later. Therefore, it is preferable that the material does not react with the liquid filled in the container or change the quality of the liquid.

  The air supply tube 30 is a tube for supplying external air to the air bag 40. The tube is inserted to the vicinity of the bottom surface of the container body 10 and has a plurality of openings 31 only on the side surface. The air bag 40 is formed in an elongated bag shape so as to cover most of the portion inserted into the container main body 10 of the air supply tube 30. The air bag 40 has an opening 41 sealed at the upper part in the bottle of the air supply tube 30, and the volume in the container can be replaced with air.

  FIG. 2 is a view for explaining the details of the air supply tube 30 and the air bag 40. As shown in the figure, the air bag 40 is formed in a shape that forms a ridge 42 whose cross section radially extends in three directions when air is not contained. Moreover, the air bag 40 has a cross-sectional shape that increases toward the bottom, and is inflated from the bottom of the container. The air bag 40 is also preferably made of a thin latex or the like that does not react with the liquid filled in the container or change the quality of the liquid and that easily expands (stretches). The air supply tube 30 and the air bag 40 constitute an air chamber. In the present embodiment, the number of the ridges 42 is 3. However, the present invention is not limited to this, and a shape having more ridges may be used in order to expand more uniformly.

  The extraction tube 50 is a tube for discharging the liquid filled in the container to the outside.

  If it is said liquid holding | maintenance container 100, a liquid can be filled in a container very easily, without making it contact with air. Specifically, first, the liquid is put into the container body 10 to the extent that it reaches the vicinity of the opening of the container. Next, the opening of the container body 10 is sealed with the stopper 20 to which the air supply tube 30, the air bag 40, and the extraction tube 50 are attached. At this time, when the air bag 40 is gradually inserted into the container from the end, the liquid level is raised by the volume, and a small amount of liquid overflows from the dispensing tube 50 when the stopper 20 is inserted. Since the inner end surface of the stopper 20 and the inner end of the dispensing tube 50 are in the same plane, air is discharged without remaining in the container, and the stopper 20 is inserted into the container body 10. Will be filled with only liquid.

  In the case of commercially available wine or the like, it is very preferable to use the bottle itself as the container body 10 because there is no need to transfer wine and even a small amount of wine can be prevented from coming into contact with air.

  [Embodiment 2] FIG. 3 is a cross-sectional view showing the shape of a liquid holding container according to Embodiment 2 of the present invention. The liquid holding container 200 mainly includes a container main body 10, a stopper 20, an air supply tube 30, an air bag 60, and an extraction tube 50. Compared to the first embodiment, the configuration of the air bag 60 is different.

  The air bag 60 covers the most part of the air supply tube 30 inserted into the container main body 10, and when filled with air, the air bag 60 is substantially the same as the shape inside the container main body 10. It is formed by joining two sheets. The air bag 60 has an opening 61 sealed at the upper part in the bottle of the air supply tube 30, and the volume in the container can be replaced with air.

  FIG. 4 is a diagram for explaining the details of the air supply tube 30 and the air bag 60. As shown in the figure, the air bag 60 formed by welding the outer periphery 62 of two synthetic resin sheets having the same shape has a straight section in a state where no air is contained, as shown in FIG. The cross section is folded and stored so as to have a spiral shape around the air supply tube 30. Although the bag itself does not expand and contract, it expands so as to be substantially the same as the shape inside the container body 10 by feeding air. The air bag 60 is also preferably an aluminum vapor-deposited laminated sheet or the like that does not react with or alter the liquid filled in the container. The air supply tube 30 and the air bag 60 constitute an air chamber.

  If it is said liquid holding | maintenance container 200, a liquid can be filled in a container very easily, without making it contact with air. Specifically, first, the liquid is put into the container body 10 to the extent that it reaches the vicinity of the opening of the container. Next, the opening part of the container main body 10 is sealed with the stopper 20 equipped with the air supply tube 30, the air bag 60, and the extraction tube 50. At this time, when the air bag 60 is gradually inserted into the container from the end, the liquid level is raised by the volume, and a slight amount of liquid overflows from the dispensing tube 50 when the stopper 20 is inserted. Since the inner end surface of the stopper 20 and the inner end of the dispensing tube 50 are in the same plane, the air is discharged without remaining in the container, and when the stopper 20 is inserted, the container body 10 is inserted. The inside is filled with only liquid.

  In the case of commercially available wine or the like, it is very preferable to use the bottle itself as the container body 10 because there is no need to transfer wine and even a small amount of wine can be prevented from coming into contact with air.

  Next, a liquid supply apparatus configured using the two types of liquid holding containers will be described.

  [Third Embodiment] FIG. 6 is a cross-sectional view showing a configuration of a liquid supply apparatus according to a third embodiment of the present invention. The liquid supply device 300 uses the liquid holding container 100, and supplies an air supply ball 70 formed of an elastic body at the end of the air supply tube 30, and extends the extraction tube 50 so that the end is directed downward. A valve 51 that can be freely opened and closed is provided on the way.

  The air supply ball 70 is a ball formed of an elastic body such as rubber, and the surface thereof has an uneven shape like a bunch of grapes and is easily gripped by a hand. When the air supply ball 70 is crushed, air is sent from the opening 71 to the air bag 40 through the air supply tube 30. In a state where the valve 51 is opened, the liquid pressurized by the expansion of the air bladder 40 is poured out from the end of the dispensing tube 50, and the liquid can be supplied. When the valve 51 is closed, the supply of the liquid is completed, and it is also possible to prevent the liquid from flowing back and air from entering the container body 10.

  The air chamber of the liquid supply device 300 is composed of the air supply tube 30 that is elongated and the air bag 40 that is elongated so as to cover it. The problem that it is difficult to supply air while trying to rise, or the remaining liquid cannot be discharged due to non-uniform expansion is eliminated. Accordingly, the liquid supply is performed with the container body 10 in an upright state. And can be stored. In addition, since the liquid does not come into contact with air at the time of supply and storage, the quality of the liquid can be maintained for a long time without being oxidized.

  [Embodiment 4] FIG. 7 is a cross-sectional view showing a configuration of a liquid supply apparatus according to Embodiment 4 of the present invention. The liquid supply apparatus 400 is configured by using a liquid holding container 100 and a manual pump 80 for sucking liquid at the end of the extraction tube 50.

  The manual pump 80 is a known pump that draws up the liquid with a negative pressure, and sucks the liquid filled in the container body 10 through the dispensing tube 50 by moving the lever 81 up and down. When the manual pump 80 is operated, the liquid sucked from the front end opening 83 of the pump is discharged. When the liquid is sucked, the inside of the container main body 10 becomes a negative pressure, so that air of the same volume as the discharged air enters the air bag 40 through the air supply tube 30 and the air bag 40 expands. When the operation is stopped in a state where the handle portion of the lever 81 is lowered, the liquid supply is finished. The liquid does not flow back and air does not enter the container body 10. The valve 84 is normally closed, but when opened, air can enter from the outside. Although the liquid 20 is almost discharged and the air bag 40 is inflated and the inside of the container body 10 is in a negative pressure state, the stopper 20 cannot be detached. be able to.

  The air chamber of the liquid supply device 400 is composed of the air supply tube 30 that is elongated and the air bag 40 that is elongated so as to cover the air supply tube 30. The problem that it is difficult to supply air while trying to rise, or the remaining liquid cannot be discharged due to non-uniform expansion is eliminated. Accordingly, the liquid supply is performed with the container body 10 in an upright state. And can be stored. In addition, since the liquid does not come into contact with air at the time of supply and storage, the quality of the liquid can be maintained for a long time without being oxidized.

  [Embodiment 5] FIG. 8 is a cross-sectional view showing a configuration of a liquid supply apparatus according to Embodiment 5 of the present invention. The liquid supply device 500 uses the liquid holding container 200, and supplies an air supply ball 70 formed of an elastic body at the end of the air supply tube 30, and extends the extraction tube 50 so that the end is directed downward. A valve 51 that can be freely opened and closed is provided on the way.

  The air supply ball 70 is a ball formed of an elastic body such as rubber, and the surface thereof has an uneven shape like a bunch of grapes and is easily gripped by a hand. When the air supply ball 70 is crushed, air is sent from the opening 71 to the air bag 60 through the air supply tube 30. In a state where the valve 51 is opened, the liquid pressurized by the expansion of the air bag 60 is poured out from the end of the dispensing tube 50, and the liquid can be supplied. When the valve 51 is closed, the supply of the liquid is completed, and it is also possible to prevent the liquid from flowing back and air from entering the container body 10.

  The air chamber of the liquid supply device 500 is composed of the long air supply tube 30 and the air bag 60 formed so as to cover the air supply tube 30, so that a vertically long balloon-like hollow body floats as in the conventional case. As a result, the problem of difficulty in supplying air due to stagnation and the problem that the remaining liquid cannot be discharged due to non-uniform expansion is eliminated. Can be stored. In addition, since the liquid does not come into contact with air at the time of supply and storage, the quality of the liquid can be maintained for a long time without being oxidized.

  [Sixth Embodiment] FIG. 9 is a cross-sectional view showing a configuration of a liquid supply apparatus according to a sixth embodiment of the present invention. The liquid supply apparatus 600 is configured by using a liquid holding container 200 and a manual pump 80 for sucking liquid at the end of the extraction tube 50.

  The manual pump 80 is a known pump that draws up the liquid with a negative pressure, and sucks the liquid filled in the container body 10 through the dispensing tube 50 by moving the lever 81 up and down. When the manual pump 80 is operated, the liquid sucked from the front end opening 83 of the pump is discharged. When the liquid is sucked, the inside of the container main body 10 becomes a negative pressure, so that air of the same volume as that discharged enters the air bag 60 through the air supply tube 30 and the air bag 60 expands. When the operation is stopped in a state where the handle portion of the lever 81 is lowered, the liquid supply is finished. The liquid does not flow back and air does not enter the container body 10. The valve 84 is normally closed, but when opened, air can enter from the outside. The plug 20 cannot be detached when the liquid 60 is almost exhausted and the air bag 60 is inflated and the container body 10 is in a negative pressure state. be able to.

  Since the air chamber of the liquid supply device 600 is composed of the long air supply tube 30 and the air bag 60 formed so as to cover the air supply tube 30, a vertically long balloon-like hollow body is lifted as in the conventional case. As a result, the problem of difficulty in supplying air due to stagnation and the problem that the remaining liquid cannot be discharged due to non-uniform expansion is eliminated. Can be stored. In addition, since the liquid does not come into contact with air at the time of supply and storage, the quality of the liquid can be maintained for a long time without being oxidized.

  [Seventh Embodiment] FIG. 10 is a cross-sectional view showing a configuration of a liquid supply apparatus according to a seventh embodiment of the present invention. The liquid supply device 700 inserts the air supply tube 30 of the air chamber (the air bag 60 and the air supply tube 30) used in the liquid holding container 200 into the connection plug 21 different from the plug 20, and penetrates to the outside. The liquid retention container portion 800 for retaining the poured liquid is provided as an apparatus above the connection plug 21.

  As shown in FIG. 11, the liquid supply apparatus 700 is configured to use a vacuumer 900 as means for sucking liquid. The vacuumer 900 is a known manual pump that generates negative pressure, and its tip 901 is inserted into a vacuumer spacer 910 that is inserted in advance into the opening 810 of the liquid retention container 800, and the lever 902 is moved up and down. Then, the air in the liquid retention container part 800 is sucked to make the inside negative pressure.

  When the inside of the liquid retention container portion 800 becomes negative pressure, the liquid filled in the container body 10 enters the liquid passage 24 of the connecting plug 21 and rises, and is discharged from the tip into the liquid retention container portion 800. The discharged liquid is held in the liquid reservoir 811 of the liquid retention container portion 800. When the liquid is discharged, the inside of the container main body 10 has a negative pressure, so that air of the same volume as that discharged enters the air bag 60 through the air supply tube 30 and the air bag 60 expands.

  When a desired amount of liquid is retained in the liquid retention container portion 800, the vacuumer 900 and the vacuumer spacer 910 are detached, and the container main body 10 is appropriately tilted while the liquid holding container portion 800 is attached, whereby the liquid is separated into another container or the like. Can be poured into. Further, when the liquid has been dispensed, the liquid retention container portion 800 can be detached from the connecting plug 21 and the liquid can be stored.

  FIG. 12 is a cross-sectional view showing the structure of the connecting plug of the liquid supply apparatus according to the embodiment of the present invention. The connecting plug 21 is formed of an elastic body, and an upper plug portion 22 is formed on the upper outer peripheral surface, and a lower plug portion 21 is formed on the lower outer peripheral surface. The upper plug portion 22 is a plug portion for fitting the liquid retention container portion 800, and the lower plug portion 23 is a plug portion for fitting the container main body 10. The plurality of projections and depressions formed on both plug portions provide sealing properties when fitted. The container main body 10 and the liquid retention container part 800 are connected by the upper stopper part 22 and the lower stopper part 23 formed in the connecting stopper 21.

  In addition, a liquid passage 24 for allowing liquid to pass from the container main body 10 side to the liquid retention container portion 800 side and an air supply tube 30 constituting an air chamber are inserted into the connection plug 21 and penetrated to the outside. An air supply passage 26 is formed. Since the valve portion 25 is formed at the tip of the liquid passage 24, the liquid once flowing into the liquid retention container portion 800 flows backward, or the air in the liquid retention container portion 800 enters the container body 10 side. There is nothing to do.

  Further, the connecting plug 21 is provided with an upper plug cap 27 that covers the plug portion when the liquid retention container portion 800 is detached and the upper plug portion 22 is exposed, and an air supply tube 30 protruding from the air supply passage 26. An air supply tube cap 28 for covering is formed. Thereby, the approach of the air to the container main body 10 side at the time of storage can be blocked | prevented reliably, and deterioration of a liquid can be prevented. Moreover, it is preferable also on hygiene. The upper cap portion cap 27 and the air supply tube cap 28 are made of the same material as the connecting plug 21 and are integrally molded including the lead connected to the connecting plug 21, and the cap may be lost when not in use. Absent.

  Next, FIG. 13 is a cross-sectional view showing the structure of the liquid retention container portion of the liquid supply apparatus in the embodiment of the present invention. The liquid retention container portion 800 includes a pair of containers having the same shape including the opening 810 and the liquid reservoir 811 and a joint 820 that connects them. The liquid retention container portion 800 is made of glass or a transparent resin, and the joint 820 is made of an elastic body such as a soft resin. The joint 820 is formed with an insertion portion 821 for inserting the divided liquid retention container portion 800 from both the upper and lower directions and a liquid trap 822 for preventing the ejected liquid from reaching the upper side. In particular, when liquid is first discharged into the liquid retention container portion 800, the liquid may be ejected vigorously. The liquid trap 822 blocks the jetted liquid from traveling upward and returns it downward. Thereby, it is possible to prevent the liquid from entering the vacuumer 900 and fouling the vacuumer 900.

  By the way, since the outer diameter of the liquid trap 822 is formed so as to be substantially the same as the inner diameter of the opening 810 of the liquid retention container portion 800, the desorbed liquid retention container portion 800 is removed as shown in FIG. If placed on another joint 820, the liquid retaining container portion 800 that is substantially cylindrical and easy to roll can be securely and safely fixed. The liquid retention container portion 800 is formed by combining a pair of containers having the same shape, so that a liquid trap can be provided and injection molding can be performed when the container is formed of resin. There is also an advantage that the degree of freedom in molding increases. In addition, after use for liquid dispensing, the container can be divided and washed and stored, so that it is excellent in maintainability and storage.

  Since the air chamber of the liquid supply device 700 is composed of the long air supply tube 30 and the air bag 60 formed so as to cover the air supply tube 30, a vertically long balloon-like hollow body floats up as in the conventional case. As a result, the problem of difficulty in supplying air due to stagnation and the problem that the remaining liquid cannot be discharged due to non-uniform expansion is eliminated. Can be stored. In addition, since the liquid does not come into contact with air at the time of supply and storage, the quality of the liquid can be maintained for a long time without being oxidized.

  As described above, according to the liquid holding container and the liquid supply device of the embodiment of the present invention, it is possible to prevent the liquid from contacting the air and to store and dispense the liquid while keeping the container upright. Can be done. Therefore, it is possible to prevent deterioration with time such as oxidation of the liquid. In particular, it is expected to be effective in the storage and supply of delicate liquids (such as wines such as wine, liquid chemicals such as vaccines, etc.) that dislike quality deterioration due to oxidation.

  Furthermore, according to the liquid holding container and the liquid supply apparatus in the embodiment of the present invention, the liquid in the upper part of the container is always poured out first. Therefore, in the case of liquids containing precipitates (impurities) (for example, those contained in wine), the liquid can be poured out without discharging them to the end.

  INDUSTRIAL APPLICABILITY The liquid holding container and the liquid supply device according to the present invention have an effect of effectively preventing deterioration of the liquid with time, and are useful as a liquid holding container and supply device whose quality is significantly deteriorated due to oxidation or the like.
