Description

  The present invention relates to a beverage container, and more particularly, to a beverage container structure capable of cooling (cooling) or warming (warming) a beverage contained in a container such as a PET bottle or a metal can.

  Today, various beverage products are sold at convenience stores, supermarkets, retail stores such as railway kiosks, and vending machines. For example, soft drinks such as fruit drinks (juice), whey drinks, mineral water, teas (green tea, black tea, oolong tea, barley tea, etc.), beer, sparkling wine, wine, chuhai, cocktails, sake, shochu, liqueur And alcoholic beverages such as whiskey.

  On the other hand, as individual packaging forms for providing these beverage products, plastic bottles such as plastic bottles, metal can containers such as steel cans and aluminum cans, and individual packaging packages such as glass bottles and paper packs are used. Yes. Furthermore, these beverage products are sometimes provided at room temperature, but in many cases, they are sold to consumers for drinking either in the state of being cooled or heated. This is because by cooling or warming the beverage, the taste and flavor of the beverage can be increased, and a refreshing feeling and warm feeling (warm taste) can be enjoyed.

Moreover, there exists the following patent document as what proposes the means to cool or heat such drink goods.
Japanese Patent Laid-Open No. 2006-52008 JP 2002-277132 A JP 2001-208465 A JP-A-8-61819

  By the way, the conventional beverage package is not sufficient in terms of cold insulation, whether it is in PET bottles, metal cans, glass bottles or paper packs. The cold beverage is warmed or warmed while drinking. Often the beverages get cold. Especially in summer when cold drinks are delicious, the temperature is high, and on the contrary, in winter when warm drinks are enjoyed, the temperature is low. Therefore, drinks that are chilled in the summer are easily heated, and drinks that are warm in the winter are quickly cooled.

  On the other hand, as a means for keeping the chilled or warmed beverage cold and warm, for example, a bag (insulated bag or warm bag) provided with a heat insulating material is used, and various types of warm and cool devices such as the above-mentioned patent documents have been proposed.

  However, these conventional cold-insulated bags and the inventions described in Patent Documents 2 to 4 are inconvenient due to the inconvenience of having to separately prepare bags and devices (heat-insulated coolers). On the other hand, since the invention of the above-mentioned Patent Document 1 adds a heat-retaining / cooling mechanism to the container itself, there is no inconvenience of preparing utensils separately from beverages. However, the container structure of this Patent Document 1 is only to block heat conduction with the outside, and the container itself cannot actively cool and warm the drink, and is sufficient in terms of the cold and warming effect. It can not be said.

  Accordingly, an object of the present invention is to obtain a new beverage container structure capable of performing cooling / cooling and warming / warming of a beverage accommodated in a beverage package even better.

  In order to solve the above-mentioned problems and achieve the object, a first beverage container according to the present invention has a container main body portion having an upper opening for taking out a beverage and capable of containing the beverage inside, and a container lid for closing the upper opening. And a cold / warm agent storage part that is formed so as to protrude from the bottom surface side of the container main body part into the container main body part and that can store the cold / warm agent.

  In the first beverage container of the present invention, the beverage is accommodated in the container body. The container body includes an upper opening, and the beverage container further includes a lid (container lid) that closes the upper opening. In order to take out the beverage from the container body, the container lid is opened and this is done through the upper opening.

  In addition, the said container main-body part, upper opening, and a container cover body are resin-made bottles (PET bottle etc.) conventionally provided, the glass bottle for drinks, cylindrical drink cans (aluminum cans, steel cans, other metal products, for example) A two-piece can is desirable, but a three-piece can or a bottle-shaped can may be used), and a beverage can (so-called “Styny bottle”) having a neck portion with a small diameter at the upper end, such as a PET bottle. Or a plastic bottle-type metal can bottle / aluminum or other metal material) or a paper container (paper pack) for beverages. By adopting the same external shape as these existing beverage containers, there is an advantage that the existing merchandise display shelves and vending machines can be used without change.

  On the other hand, the first beverage container of the present invention includes a cold / warm agent storage portion formed so as to protrude from the bottom surface side of the container main body portion to the inside of the container main body portion, unlike a conventional beverage container. This cold / warm agent storage part stores the cold / warm agent.

  Here, “cold / cooling agent” refers to a substance having a temperature lower than normal temperature or higher than normal temperature and capable of exchanging heat with a beverage stored in a container body. The cryogen is not particularly limited to a specific one, and widely includes materials that can cool or warm the beverage. If an example of the cold / warm agent (henceforth a cooling agent) used for cooling is described, ice and a cold insulating agent will be mentioned, for example. Further, a substance capable of lowering the freezing point (melting point) of ice (for example, sodium chloride) may be used together with ice, and according to this, the cooling efficiency can be increased.

  In the case of using a cold insulation agent as the cold / warm agent, for example, the beverage container is disposed at the lower portion of the cold insulation agent main body portion having a shape substantially matching the internal space of the cold / warm agent storage chamber, and the lower portion. What is necessary is just to further provide the cold insulating agent which has a latching | locking part latchable to opening. Compressed gas is also included in the cryogenic agent according to the present invention. In this case, for example, it may have a structure like the second beverage container of the present invention described later.

  On the other hand, an example of a cold / warm agent used for warming (hereinafter sometimes referred to as a warming agent) is, for example, hot water. Various exothermic substances that generate heat by mixing two or more substances can also be used as a cooling / heating agent (heating agent).

  In the present invention, “cooling”, which is an operation for cooling a beverage that has not yet been cooled (for example, at a temperature above room temperature), and a beverage that has already been cooled (for example, at a temperature lower than room temperature) is maintained in a cooled state. Both concepts of “cooling” are included. Similarly, “warming” that warms a beverage that has not yet been warmed (for example, at a temperature below room temperature) and “heat retention” that maintains a warmed beverage (for example, that is at a temperature higher than room temperature). The present invention includes both concepts.

  The kind of the drink accommodated in the container of the present invention is not particularly limited. For example, soft drinks such as fruit drinks (juice), mineral water, teas (green tea, black tea, oolong tea, barley tea, etc.), whey drinks, beer, sparkling wine, wine, Chuhai, cocktails, Japanese sake, shochu・ Alcoholic beverages such as liqueur and whiskey, and fluid foods such as yogurt, jelly, and jelly supplements are included.

  In the above beverage container of the present invention, the upper end is closed, while the lower body has a lower opening having a lower opening that opens to the bottom surface portion of the container main body and allows the loading of the cold / warmant, and the lower opening. You may make it a cryogenic agent storage part equip with the lower cover body or lower plug body which obstruct | occludes. Further, the cold / warm agent storage chamber can be integrally formed with the container main body. Thus, if the cold / warm agent storage chamber and the container main body are integrally formed, there is an advantage that the beverage container of the present invention can be manufactured at a low cost by a simple operation.

  It is desirable that the cold / warm agent storage chamber has a height of one half or more of the container main body within a range not reaching the upper opening. This is to increase the cooling or heating efficiency of the beverage contained in the container main body. Furthermore, for the same reason, the side wall of the cold / warm agent storage chamber may be provided with irregularities that enhance the efficiency of heat exchange with the beverage stored in the container body. The shape of the unevenness is not particularly limited as long as it can increase the surface area of the cold / warm agent storage chamber, and may be, for example, a bowl shape (fin shape), a protrusion shape, or other structures.

  The lower cover body includes a bottom plate portion that opposes the lower opening and closes the lower opening. The bottom plate portion has flexibility and is curved so as to swell downward, and the bottom plate portion is accommodated with a cooling / heating agent. While it can be depressed by pressing toward the room, it may be able to return to the original position by removing the pressing force.

  If such a lower lid is provided, by repeatedly pressing the bottom plate portion of the lower lid with, for example, a finger, the cold / warm agent stored in the cold / warm agent storage chamber is stirred to improve the cooling or warming efficiency of the beverage. I can do it.

  In addition, the lower lid can close the lower opening while being ruptureable, and can store an additive to the cold / warm agent formed in the lower part of the closed sheet and loaded in the cold / warm agent storage chamber. The additive storage chamber may be provided, and the additive may be mixed with the cooling / heating agent loaded in the coolant storage chamber by breaking the blocking sheet.

  According to such a container structure, by adding various additives that increase the cooling efficiency or the heating efficiency, the temperature of the cooling / heating agent loaded in the cooling / heating agent storage chamber is lowered or increased and accommodated in the container main body. Beverages can be made even colder or hotter.

  As the additive, for example, sodium chloride which is a melting point depressant can be used. If this is added to ice as a cooling agent, the melting point of the ice is lowered, and the temperature in the cooling agent storage chamber is further reduced. This allows the beverage to cool rapidly and again to a lower temperature. Moreover, when using a warming agent (when warming a drink), in addition to the said warming agent, the substance which generate | occur | produces heat can be used as said additive.

  Moreover, in the said container structure, the baseplate part which forms an additive storage chamber has flexibility, and when the said baseplate part is pressed and deformed, the said closure sheet | seat may be made ruptureable. According to such a structure, when the melting point depressant is loaded in a tablet or a water-soluble capsule, since the melting point depressant itself has rigidity, the bottom plate portion of the additive storage chamber is pressed. For example, the blocking sheet can be broken by the melting point depressant, and the melting point depressant can be fed into the cold / warm agent storage chamber through the lower opening.

  On the other hand, when the melting point depressant is a granule or a powder, a tray having rigidity capable of breaking the closing sheet may be disposed in the additive storage chamber, and the melting point depressant may be stored in this tray. If such a tray is used, even if the melting point depressant is in the form of granules or powder, the bottom plate part of the additive storage chamber is similarly pressed, and the melting point depressant is cooled by breaking the closing sheet with the tray. It can be sent to the agent storage room.

  Furthermore, in the beverage container of the present invention, the upper end portion of the container main body portion has a neck portion having the upper opening and a reduced diameter, and the neck portion is arranged so as to be rotatable relative to the container main body portion. A ring may be provided, and the beverage container may be rotatably supported by gripping the rotating ring. The reason for providing such a ring is as follows.

  The chilling agent stored in the chilling agent storage chamber exchanges heat with the beverage in the container body, but as time passes, the chilling agent layer (close to the wall) near the wall of the chilling agent storage chamber (along the wall surface) ( A so-called boundary layer is formed, and cooling (or heating) efficiency decreases. In order to prevent such a decrease in cooling (or heating) efficiency, it is necessary to stir the cooling / heating agent in the cooling / heating agent storage chamber. In this stirring operation, if the beverage in the container main body is not foaming (for example, carbonated beverage or beer), the container can be simply held and shaken up and down. However, if the beverage has foaming properties, it is not preferable to shake the container because the beverage may spout when the container lid is opened. Therefore, in the present invention, a rotating ring as described above is provided, and this ring is supported by being pinched with, for example, a finger, and it is possible to stir the cold / warm agent by rotating the container. As a result, the boundary layer can be prevented from being generated, and the cooling (or heating) efficiency can be prevented from being lowered.

  The rotating ring may have a larger outer diameter than the container lid, and may protrude outward from the outer peripheral surface of the container lid. This is to make it easier to grip the rotating ring. The rotating ring may also serve as a sealing ring for sealing the container lid. According to this, it becomes possible to provide a rotating ring in a beverage container without increasing the number of parts of the beverage container. In this case, it is preferable that the width of the rotating ring is wider than that of the existing sealing ring because the rotating ring is easily grasped. The rotating ring may be disposed, for example, at a lower position of the container lid body (adjacent to the container lid body and at a lower position thereof).

  The second beverage container of the present invention is a beverage container comprising a container main body portion having an upper opening for taking out a beverage and capable of containing a beverage therein, and a container lid for closing the upper opening, A cooling agent storage portion that is formed so as to protrude from the bottom surface side of the container main body portion into the container main body portion and that can store a coolant; and the cooling agent storage portion is provided on the bottom surface portion of the container main body portion. A cylinder storage part that has a lower opening and can store a gas cylinder filled with compressed gas from the lower opening, and is disposed in the upper part of the cylinder storage part and closed at the upper end, while being stored in the cylinder storage part. A gas inlet that can communicate with the gas cylinder is provided at the lower end, and a cooling chamber is provided through which the gas from the gas cylinder can be introduced.

  In the second beverage container of the present invention, compressed gas is used as a cold / warm agent (coolant). The gas cylinder filled with the compressed gas is loaded into the cylinder storage unit from the lower opening provided in the bottom surface of the container main body. A cooling chamber is provided in the upper part of the cylinder storage unit, and when a gas cylinder is loaded into the cylinder storage unit, the compressed gas in the gas cylinder is discharged to the cooling chamber through the gas inlet port provided in the lower end of the cooling chamber. The cooling chamber is cooled to exchange heat with the beverage in the container body, and the beverage in the container body is cooled.

  Even in this second beverage container, in order to increase the cooling or heating efficiency of the beverage contained in the container main body, the cooling chamber does not reach the upper opening in the range of 2 of the container main body as in the case of the first beverage container. It is desirable to have a height of 1 / min or more. Moreover, you may equip the side wall of a cooling chamber with the unevenness | corrugation which improves the heat exchange efficiency with the drink accommodated in the container main-body part.

  For the container body, as in the first beverage container, the container body, upper opening, and container lid are, for example, conventionally provided resin bottles (such as plastic bottles), glass bottles for beverages, and beverages. It is possible to have the same outer shape and structure as a can and a beverage paper container (paper pack).

  On the other hand, the beverage container attachment according to the present invention has an upper opening for taking out a beverage and can contain a beverage inside, a container lid that closes the upper opening, and a cooling / heating agent inside. And is formed so as to protrude from the bottom surface side of the container main body to the inside of the container main body, the upper end is closed, and the bottom of the container main body can be opened to be loaded with the cooling / heating agent. An attachment for a beverage container, which is attached to a bottom surface portion of a beverage container having a cooling agent storage chamber having a lower opening at the lower end thereof and extends the cooling / warming agent storage chamber, and engages with the bottom surface portion of the beverage container. Engaging means for enabling the attachment to be supported on the beverage container, and an expansion chamber that can be filled with a chilling agent and communicates with the chilling agent storage chamber through the lower opening.

  The beverage container attachment of the present invention is attached to a beverage container having the same structure as the first beverage container according to the present invention (container body, container lid and cold / warm agent storage chamber), and the cold / warm agent storage chamber To increase the capacity.

  Since the cold / warm agent storage chamber is provided so as to protrude into the container main body, the larger the cold / warm agent storage chamber, the smaller the volume of the container main body, and the amount of beverage that can be stored decreases. On the other hand, if the size of the chilling agent storage chamber is reduced in order to increase the amount of beverage that can be accommodated, the cooling (or heating) capacity must be reduced accordingly. Therefore, in the present invention, it is possible to increase the cooling / heating agent storage chamber and increase the cooling (or heating) capacity.

  Specifically, the attachment includes an expansion chamber that is supported on the bottom surface of the beverage container by the engaging means and communicates with the cold / warm agent storage chamber of the beverage container. It is preferable that the engagement means is configured so that the attachment can be detachably attached to the beverage container. If it is made detachable in this way, for example, when the beverage is cold or not warmed, by changing another attachment, or by removing the attachment and replacing the cryogenic agent, the beverage can be cooled to a lower temperature (or higher temperature). In addition, it is possible to cool (or warm) over a long time.

  As a specific configuration of the engaging means, for example, a screw may be formed in the lower opening portion of the beverage container, and a screw that can be screwed into the screw may be provided in the attachment. Further, a fitting or other engagement structure may be used instead of the screw.

  The attachment further includes an additive storage chamber capable of storing an additive to be added to the cryogenic agent loaded in the expansion chamber, and the additive stored in the additive storage chamber is loaded into the expansion chamber. It is good also as mixing with respect to the done cryogenic agent. This additive or additive storage chamber is similar to the additive or additive storage chamber provided in the first beverage container of the present invention, and is a space (room / additive) separated from the expansion chamber in the attachment. The storage chamber is formed so that the additive can be stored in the space, while the space and the expansion chamber are communicated with each other by a certain operation so that the additive can be put into the expansion chamber.

  As one configuration example of the additive storage chamber, an additive storage chamber is provided on the bottom surface portion of the attachment, and the additive storage chamber has a breakable closing sheet separating the additive storage chamber from the expansion chamber on the top surface portion. On the other hand, a bottom plate portion having flexibility (or elasticity) is provided on the bottom surface of the attachment, and the blocking sheet can be broken by pressing and deforming the bottom plate portion.

  For example, a melting point depressant containing sodium chloride as a main component is stored in the additive storage chamber. The melting point lowering agent is, for example, one loaded in a tablet or a water-soluble capsule. Alternatively, the melting point depressant may be a granule or a powder, and a tray having rigidity capable of breaking the closing sheet may be disposed in the additive storage chamber, and the melting point depressant may be stored in this tray.

  Further, the tray is rotatably supported by a support shaft at one end portion of the additive storage chamber, and when the bottom plate portion is pressed and deformed, the tray rotates about the support shaft, whereby the closing sheet May be broken. If the tray is supported by the support shaft in this way, the tray is not put into the cooling chamber, and only the additive can be added to the cooling chamber.

  In addition, the upper surface of the tray is provided with a sheet breaking blade that protrudes substantially horizontally from one end of the tray provided with the support shaft toward the substantially central portion of the tray, and thereby the tray centered on the support shaft. The sheet breaking blade may break the closing sheet in accordance with the rotation operation. If such a sheet breaking blade is provided, it becomes possible to break the closing sheet more easily and add the additive to the cold / warm agent. As a preferable aspect of this sheet breaking blade, for example, it is assumed that it has a substantially fan-shaped planar shape with a pointed tip toward the center of the tray. Such a sheet breaking blade may be fixed to the tray, or may be fixed to the lower surface of the closing sheet to be disposed on the upper surface of the tray.

  Furthermore, a heat insulating material can be provided on the outer peripheral surface of the expansion chamber. According to such a structure, the cooling agent in the expansion chamber can be kept cold (or kept warm), and heat can be prevented from flowing in (or dissipating outside) from being heated (or cooled). I can do it. In addition, it is possible to prevent a situation in which the attachment is cold (or hot) and cannot be held by hand due to the stored cold / warm agent.

  In addition, another beverage container according to the present invention has an upper opening for taking out a beverage and can accommodate a beverage inside, a container lid for closing the upper opening, and a cooling / heating agent inside. And is formed so as to protrude from the bottom surface side of the container main body to the inside of the container main body, the upper end is closed, and the bottom of the container main body can be opened to be loaded with the cooling / heating agent. A beverage container provided with a cold / warm agent storage chamber having a lower opening at the lower end, and any beverage container attachment according to the present invention.

  Furthermore, the beverage in a container according to the present invention is obtained by storing a beverage in the container main body portion of any of the beverage containers according to the present invention. The type of the beverage is not particularly limited, and may be, for example, the above-described various beverages (soft drinks such as fruit drinks, mineral water, teas, and whey drinks, alcoholic drinks, fluid foods, and the like).

  According to the beverage container of the present invention, the beverage contained in the beverage package can be cooled and kept warm and warmed and kept warm.

  Other objects, features, and advantages of the present invention will become apparent from the following description of embodiments of the present invention described with reference to the drawings. In addition, in each figure, the same code | symbol shows the same or an equivalent part.

[First embodiment (plastic bottle / lower lid)]
1 to 4 show a plastic bottle (beverage container) according to a first embodiment of the present invention. As shown in these figures, this plastic bottle is made of a material mainly composed of polyethylene terephthalate, and has a bottle body 1 having an opening (drinking mouth) 2 at the upper end, like a conventional plastic bottle, A screw cap (screwed lid) 3 for closing the drinking mouth 2 is provided. Various drinks can be placed in the bottle body 1 in the same manner as a conventional PET bottle, and the drinking mouth 2 is closed by a cap 3. A beverage purchaser can open the cap 3 and drink the beverage in the bottle body 1 through the drinking mouth 2 in the same manner as before.

  On the other hand, the plastic bottle according to the present embodiment includes a cooling chamber 11 that protrudes from the bottom of the bottle into the bottle body 1. The cooling chamber 11 is formed by integrally forming a partition wall 10 that stands substantially vertically upward from the center of the bottom surface of the bottle toward the drinking mouth 2, and has a substantially constant outer diameter smaller than the inner diameter of the bottle. The bottom of the bottle 2 reaches the position near the lower portion of the drinking mouth 2, the upper end is closed, and the lower end is opened on the bottle bottom. The partition wall 10 is continuous (integral) with the bottom plate 4 of the bottle main body 1, so that the beverage inside the bottle main body enters the cooling chamber 11, or conversely, the coolant in the cooling chamber 11 is transferred to the bottle main body 1. It does not penetrate inside.

  The lower opening 12 at the lower end of the cooling chamber 11 is closed by mounting a screw cap (hereinafter referred to as the lower lid) 15 different from the screw cap (hereinafter referred to as the upper lid) 3 for closing the drinking mouth 2. . The inner surface of the lower lid 15 is provided with a packing 17 so as to prevent the ice water entering the cooling chamber 11 from leaking, so that a watertight structure is provided. The lower lid 15 is made of resin, and the bottom plate 16 is shaped to be thin and curved downward, whereby the bottom plate 16 can be recessed. Further, when the indented force is removed, the bottom plate 16 returns to a state where it is swollen downward. In addition, this lower lid 15 (the same applies to the lower stopper 25 described later) does not protrude downward from the bottom of the bottle so as not to disturb the standing of the bottle. Further, a gap is formed around the lower lid 15 with the bottle bottom plate 4 so that the lower lid 15 can be easily rotated.

  For example, ice (not shown) can be placed in the cooling chamber 11 as a coolant, whereby the beverage inside the bottle body 1 can be cooled and kept cold. Further, salt (sodium chloride) may be added together with the ice, and in this way, the cooling efficiency can be increased. Further, as described above, since the bottom cover 15 can repeatedly dent the bottom plate 16, when ice is poured into the cooling chamber 11 and melts into ice water, the bottom cover 15 is covered with, for example, a finger. By repeatedly pressing the bottom plate 16, the ice water in the cooling chamber 11 can be stirred, and the cooling efficiency can be further enhanced.

  The PET bottle of the present embodiment has substantially the same shape and size as an existing PET bottle as the overall shape of the bottle. Therefore, existing display shelves and vending machines can be used as they are without changing anything in the display of merchandise at the storefront or in delivery to vending machines. In the bottle of this embodiment, both the bottle body 1 and the partition wall 10 defining the cooling chamber 11 are transparent (having translucency), and the cooling chamber 11 itself and ice in the cooling chamber 11 are viewed from the outside of the bottle.

The lower opening 12 of the cooling chamber 11 is closed.

  The lower plug 25 is a screw plug having a screw formed on the peripheral surface, and the lower plug 25 is formed on the inner surface of the lower end of the cooling chamber 11 by screwing the screw into the lower end of the cooling chamber 11. It was possible to screw in. Further, a packing 17 is provided between the lower plug 25 and the lower end opening 12 of the cooling chamber 11 in the same manner as the lower lid of the first embodiment so that ice water in the cooling chamber 11 does not leak. It is a watertight structure. In addition, the lower surface of the lower plug 25 is provided with a knob portion 26 that protrudes downward and extends so as to longitudinally cut a central portion of the lower surface of the lower plug to the left and right (diameter direction). The lower plug 25 can be easily rotated by pinching and rotating to open and close the lower plug 25.

  Further, FIG. 8 shows a modification of the plastic bottle of the present embodiment. As shown in this figure, if the irregularities 10a are provided by forming the partition wall 10 of the cooling chamber in a wave shape, the surface area of the partition wall 10, that is, the cooling chamber 11 (coolant contained inside) and the bottle body 1 (bottle) Since the contact area with the beverage contained in the body can be increased, a better cooling effect can be obtained. The same applies to other embodiments.

[Third Embodiment (Pet Bottle / Cold Insulating Member)]

As shown in these drawings, this PET bottle includes a bottle body 1 and an upper lid 3 as in the PET bottles according to the first and second embodiments, and is cooled so as to protrude from the bottom of the bottle into the bottle body 1. Although it has the chamber 11, the cooling member 31 is provided as a coolant put in the cooling chamber 11. FIG.

  The cooling member 31 has an outer shape substantially coinciding with the cooling chamber 11 (having substantially the same (slightly smaller) outer diameter than the inner diameter of the cooling chamber 11 so as to be inserted into the cooling chamber 11). It comprises a main body 32 and an engaging portion 35 provided at the lower end of the cooling member main body 32. The cooling member main body 32 is loaded with a cooling agent 33 therein. If the cooling member 31 is cooled in a refrigerator, for example, the cooling member main body 32 is fixed by the cold insulating agent 33 loaded therein. It has been cooled for hours.

  On the other hand, the engaging portion 35 is formed with a screw on the outer peripheral surface thereof, and a knob portion 36 is provided on the lower surface thereof, like the lower plug 25 of the second embodiment. Also in the present embodiment, a screw to be screwed with the screw of the engaging portion 35 is formed on the inner surface of the lower end portion of the cooling chamber 11. Therefore, the cold insulation member 31 can be easily attached to the plastic bottle by inserting the cold insulation member main body portion 32 into the cooling chamber 11 and screwing the engaging portion 35 into the lower opening of the cooling chamber 11. The beverage contained in 1 can be cooled.

[Fourth Embodiment (Pet Bottle / Compressed Gas)]
11 and 12 show a plastic bottle according to the fourth embodiment of the present invention. As shown in these drawings, this PET bottle includes a bottle body 1 and an upper lid 3 as in the PET bottles according to the first to third embodiments, and has a cooling chamber 11 at the center of the bottle body 1. However, compressed gas is used as a coolant.

  Specifically, similarly to the plastic bottles according to the first to third embodiments, the cooling portion is formed so that the bottom surface of the bottle protrudes upward from the central portion of the bottom surface of the bottle. This cooling part is formed in a cylindrical shape with a hollow inside by a partition wall 10 rising integrally from the bottom surface of the bottle (bottom plate 4), reaching the lower position of the drinking mouth 2 and closing the upper end, The lower end is an opening. A small gas cylinder 41 filled with compressed gas can be inserted into the lower opening. A screw is formed on the peripheral surface of the small gas cylinder 41, and a screw that is screwed to the screw is formed on the inner peripheral surface of the lower end of the cooling unit (partition wall 10), so that the small gas cylinder 41 can be screwed into the lower opening. .

  In addition, a cooling chamber 11 for receiving the gas discharged from the gas cylinder 41 is provided at the upper part of the lower end of the cooling section to which the gas cylinder 41 is mounted. The cooling chamber 11 has a small hole 39 at the lower end. When the gas cylinder 41 is screwed into the lower opening of the cooling unit, the nozzle 42 of the gas cylinder 41 comes into contact with the small hole 39 and the cooling chamber 11 passes through the small hole 39. The gas in the gas cylinder 41 is released inside. The compressed gas released into the cooling chamber 11 expands, whereby the cooling chamber 11 is rapidly cooled. A knob portion 43 is provided on the lower surface of the gas cylinder 41 in the same manner as the lower plug 25 so as to facilitate the rotation (screwing) operation.

  The nozzle mechanism of the gas cylinder can be configured by applying a conventional nozzle structure used in insecticides and various spray products. The kind of compressed gas is not particularly limited. For example, carbon dioxide gas or inert gas can be used. If the gas cylinder 41 is loosened (not screwed to the uppermost position but screwed to the middle position of the lower opening), the compressed gas in the cylinder is not released because the nozzle 42 does not engage with the small hole 39 of the cooling chamber, Therefore, it is possible to temporarily stop the cooling.

  Furthermore, in this embodiment (FIG. 12), the cooling chamber 11 is provided inside the partition wall 10, and two wall bodies are interposed between the bottle body inside (beverage) and the cooling chamber inside (gas). It is also possible to use a single wall (only the bottom wall 11b is provided without providing the peripheral wall 11a of the cooling chamber). If it does in this way, since the heat exchange efficiency between a drink and cooling gas can be improved, a drink can be cooled more satisfactorily.

As shown in these drawings, this can is a two-piece can made of aluminum, and is formed by an aluminum plate in which a peripheral wall 6 forming a peripheral surface of the can and a bottom plate 4 forming a bottom surface are continuous. Furthermore, in the can of this embodiment, the partition 10 is formed so that it may stand in the inside of the can continuously with the bottom plate 4, and the cooling chamber 11 is comprised, and the lower cover 15 which obstruct | occludes the lower opening of this cooling chamber 11 is provided. Since each structure of these partition walls 10 thru | or the cooling chamber 11, and the lower cover 15 is the same as that of the bottle of said 1st embodiment, the same code | symbol is attached | subjected and the overlapping description is abbreviate | omitted.

  The overall shape of the can is the same as that of an existing beverage can, and an open tab 5 is provided on the upper surface. In addition to aluminum, steel and other metals can be used as the material constituting the can. Furthermore, not only a 2 piece can but a 3 piece can may be used.

[Eighth to tenth embodiments (can / bottom stopper, cold insulation member, compressed gas)]
Also in the can container, the plug 25 is used as a means for closing the lower opening of the cooling chamber 11 as in the second embodiment (see the eighth embodiment / FIG. 24), and similarly to the third embodiment. The cold insulation member 32 is attached to the cooling chamber 11 (see the ninth embodiment / FIG. 25), and the compressed gas filled in the compression cylinder 41 is used as the coolant (the tenth embodiment / (See FIG. 26).

[Eleventh embodiment (melting point depressant addition part)]
27 to 28 show a bottom surface portion of a beverage container according to the eleventh embodiment of the present invention. In the description of the first embodiment, it has been described that sodium chloride (melting point depressant) may be added to the coolant (ice) in the cooling chamber 11, but such an additive to be added to the coolant is previously added to the container. The present embodiment shows an example of the structure that can be provided.

  Specifically, as shown in FIGS. 27 to 28, an additive 75 is provided as a lid for closing the lower opening 12 instead of the lower lid 15 for closing the lower opening 12 provided at the lower end of the cooling chamber 11. A cap 71 containing an additive is provided. As shown in FIG. 28, the additive-containing cap 71 closes the lower opening 12 and forms an additive packaging body 79 that forms a storage chamber 72 for the additive 75, and holds the additive packaging 79 against the lower opening 12. A presser cap 77 that is attached and fixed, and a packing 78 that is interposed between the additive package 79 and the lower opening 12 so as to prevent water from leaking from the lower opening 12 are provided.

  The additive package 79 can take the same structure as, for example, PTP packaging (Press Through Package) used for packaging tablets, and includes a recess 73a that is recessed to accommodate the additive 75; A hat-shaped resin cover 73 provided with a flange 73b projecting from the upper edge of the recess 73a to the periphery, and a water-impermeable film (blocking sheet) adhered to the upper surface of the resin cover 73 so as to close the recess 73a ) 74, and the additive (sodium chloride) 75 is stored in the recess 73 a (additive storage chamber 72) of the resin cover 73. The resin cover 73 has flexibility and can be recessed by applying a pressing force. Moreover, the water-impermeable film 74 can be comprised, for example with an aluminum film, and can be penetrated with the additive 75 by pressing the resin cover 73 (recessed part 73a), while not allowing water to pass through.

  The additive (sodium chloride) 75 stored in the package may be stored in the package 79 as long as it is processed into a tablet. On the other hand, when the additive is in the form of powder or granules, it may be stored in the package 79 after being stored in the rigid tray 76 so that the water-impermeable film 74 can be easily broken through.

  A screw (male screw) S2 is formed on the outer peripheral surface of the lower end portion of the cooling chamber 11, and the presser cap 77 is provided with a screw (female screw) S1 screwed into the screw S2 on the inner peripheral surface. The presser cap 77 is provided with a hole 77a through which the recess 73a of the packaging body 79 can be passed, and the recess 73a is protruded downward from the bottom surface of the presser cap 77 through the recess 73a. On the other hand, the flange portion 73b of the packaging body 79 is pressed against the bottom surface of the edge of the lower opening 12, thereby fixing the additive packaging body 79 to the lower opening 12.

  In this fixed state, the water-impermeable film 74 adhered to the upper surface of the resin cover 73 is pressed against the lower opening 12, and the packing 78 is interposed between the water-impermeable film 74 and the edge bottom surface of the lower opening 12. As a result, the lower opening 12 is closed in a watertight state. In order to add the additive 75 to the coolant 11, the recess 73 a of the additive package 79 is pressed from the bottom of the container, and the water-impermeable film 74 is pierced by the additive 75 or the rigid tray 76 to enter the cooling chamber 11. The additive 75 may be pushed in.

  In the present embodiment, only the bottom surface of the container is shown and the upper part of the container is not shown, but the upper part of the container may have various shapes and materials. For example, it may be a plastic bottle as in the first embodiment (FIGS. 1 to 4), a glass bottle as in the fifth embodiment (FIGS. 13 to 16), or the seventh embodiment (FIG. 20). 23) A metal can such as FIG. 23), a metal can having a neck portion with a small diameter at the upper end thereof (a so-called Steiny bottle or a PET bottle-type metal can bottle), or the like may be used.

[Twelfth Embodiment (Metal Bottle with Attachment)]
29 to 30 show a beverage container according to a twelfth embodiment of the present invention. As shown in these drawings, this beverage container is composed of a metal bottle (or a resin bottle) having a neck portion at the drinking mouth portion at the upper end of the container like a plastic bottle, and is similar to the first embodiment. The bottle is provided with a drinking mouth and an upper lid 3 for closing the mouth, and a cooling chamber 11 is provided inside the bottle main body (beverage container main body) 1 for containing a beverage so as to protrude from the bottom of the container. 29 and FIGS. 31 to 34 described later conceptually show the internal structure of the container and the attachment as in FIG. 4 and the like, but unlike FIG. 4 and the like, the meat of the bottle and the attachment The thickness is not displayed, but is indicated by a simple line.

  On the other hand, the bottle of this embodiment is provided with a rotating ring 51 at the neck portion. The rotating ring 51 is rotatably attached to a position directly below the upper lid 3. If the ring 51 is gripped, the bottle body 1 can be easily rotated. In this type of bottle, a sealing ring 3a is conventionally provided to seal the upper lid 3. In this embodiment, a rotating ring 51 is provided separately from the sealing ring 3a. It is also possible to form the ring 3a wide so that the sealing ring 3a also serves as the rotating ring 51, or to provide the rotating ring 51 so as to cover the conventional sealing ring 3a. In the case of such a structure, when the bottle 1 is rotated, the upper lid 3 is once opened so that the sealing ring 3a (the rotating ring 51) can freely rotate.

  Furthermore, in this embodiment, the attachment 61 which can be mounted | worn with the lower opening 12 of the cooling chamber 11 is provided. The attachment 61 allows the cooling chamber 11 to be expanded. A cylindrical main body 63 for forming an expansion chamber 62 for accommodating a coolant (not shown), and the main body 63 A connecting portion 64 that protrudes in a cylindrical shape on the upper surface and has an opening 66 for connection at the upper end to allow the cooling chamber 11 and the expansion chamber 62 to communicate with each other is provided. A screw S <b> 1 is formed on the inner peripheral surface of the lower end portion (lower opening 12) of the cooling chamber 11, and a screw S <b> 2 that engages with the screw S <b> 1 is formed on the outer peripheral surface of the connection portion 64 of the attachment 61. Therefore, it is possible to fix the attachment 61 to the lower opening 12 by screwing the connecting portion 64 into the cooling chamber 11 (lower opening 12).

  Further, a packing P is interposed between the attachment 61 and the bottle main body 1 to prevent water from leaking between the bottle main body 1 and the attachment connecting portion 64. More specifically, a ring-shaped packing P is provided so as to surround the periphery of the connection portion 64 on the upper surface of the attachment main body 63, and this packing P is accompanied by a screwing operation of the attachment 61 to the lower opening 12. What is necessary is just to comprise so that it may be pressed on the bottom face of the bottle main body 1. FIG. In addition to this example, the watertight structure can adopt various methods and is not limited to this example.

  Furthermore, an additive 75 to be added to the coolant is provided in advance on the bottom surface of the attachment 61. The additive storage portion 71 that stores the additive 75 may have, for example, the same principle (structure) as that of the eleventh embodiment. Specifically, for example, as shown in an enlarged view in FIG. 30, a space (additive that can accommodate the additive 75 by providing an opening in the bottom plate of the attachment main body 63 and raising the bottom plate toward the inside of the main body. Storage chamber) 72 is formed. Then, the additive storage chamber 72 and the expansion chamber 62 are separated by covering the upper surface of the additive storage chamber 72 with a water-impermeable film 74, while the lower surface of the storage chamber 72 (formed on the bottom plate of the attachment main body 63). The opening) is closed by a sheet 73 having flexibility (or stretchability). In the additive storage chamber 72, a tablet-shaped or granular or powdered additive 75 stored in a tray 76 is stored. Thus, by pressing the sheet 73 upward, the additive 75 stored in the storage chamber 72 is pushed up, and the additive 75 can be fed into the expansion chamber 62 through the water-impermeable film 74.

  Moreover, the lower end part (joining part with the main-body part 63) 67 of the connection part 64 connected with the attachment main-body part 63 (expansion chamber 62) is made into the shape which rounded the corner over the perimeter (what is called rounded). . This is because the ice in the expansion chamber 62 can be smoothly fed into the cooling chamber 11 of the bottle body 1. In particular, when a large amount of square (cubic / angular) ice is placed in the expansion chamber 62, the ice smoothly moves between the cooling chamber 11 and the expansion chamber 62 without being caught by the rounded corner portion 67. It can be made.

  Furthermore, in this embodiment, the additive storage portion 71 projects upward (in a trapezoidal shape) like a plateau at the center of the bottom surface of the expansion chamber 62, and the bottom surface of the expansion chamber 62 is not flat. Therefore, when ice is put in the expansion chamber 62, there is an advantage that the ice is less likely to be a lump than when the bottom surface is flat. When the ice in the expansion chamber 62 hardens and becomes large, there may occur a situation in which the ice cannot be supplied to the cooling chamber 11 because it cannot pass through the lower opening 12 (connecting portion 64), but according to the attachment structure of the present embodiment, Such a situation can be prevented.

  Further, as shown in FIG. 34, the attachment 61 may be provided with a heat insulating material 68 around the attachment 61. According to such a structure, it is possible to cool the beverage for a longer time by keeping the ice in the expansion chamber 62 cold, and to make it easier to hold the beverage container by hand because the outer surface of the attachment 61 does not become low temperature. (In particular, when a melting point depressant is added, the attachment 61 is in a low temperature state lower than 0 ° C.), and the feeling of use can be improved. Note that the same effect can be obtained even if the attachment 61 itself is made of a highly heat-insulating material (for example, a resin having a large heat insulating property).

  The overall shape of the bottle may be various in addition to the illustrated example, as described in the eleventh embodiment. In addition, the attachment 61 can be screwed into the lower opening 12 of the cooling chamber 11 instead of the bottom plug 25 of the second embodiment (FIG. 5) or the eighth embodiment (FIG. 24), for example. If this is the case, it can be attached to other bottles, cans, etc., as in this embodiment. The attachment 61 may be provided together with the bottle, or the attachment 61 may be provided separately from the bottle. For example, the attachment 61 can be sold together with ice in a state where ice is put in the expansion chamber 62. In this case, the upper end opening 66 of the connecting portion 64 may be closed by providing a lid or a stopper.
