  In recent years, there are voices of anxiety about tap water due to environmental problems, etc., and tap water has a peculiar odor, so natural water (groundwater) that emphasizes the taste of water that you do not want to use for cooking or drinking directly. Beverage servers such as water servers are widely used due to the desire to use the food easily.

  Such a beverage server is provided as a cold water hot water apparatus in which a bottle filled with a beverage is set and cold water of 5 ° C. to 10 ° C. and hot water of 80 ° C. to 90 ° C. comes out. When the bottle becomes empty, the bottle must be replaced. And since the bottle used for the conventional drink server provided the thing of 8 liters or more, it was heavy and the replacement | exchange operation | work of the said bottle became heavy labor. In particular, in the case of an upright type water server in which the tank is installed on the upper part of the server, it is necessary to lift the tank filled with water of 10 liters or more, which is very hard work.

  Therefore, various proposals have been made so far in order to reduce the heavy labor of installing this tank. For example, in patent document 1 (Unexamined-Japanese-Patent No. 2011-213411), the drinking water of a commercially available plastic bottle can be utilized with respect to the apparatus which supplies the drinking water in a gallon bottle called a water server etc. Caps and adapters for doing so have been proposed.

  As described above, various ideas for using a small container such as a commercially available plastic bottle have been proposed in order to reduce labor at the time of bottle replacement. However, in the technique proposed in the above-mentioned patent document, a circular rubber is used to close the water guide hole, and a winding spring must be used to close the water guide hole with the circular rubber.

  In this regard, in recent years, consumers are interested in the water server, especially in terms of hygiene. This means that even for containers filled with water, a crushable bottle (disposable) that does not allow air to enter the container, rather than a gallon bottle type water server (contractor recovery type) where outside air enters the bottle each time it is used. ) Is also well received.

  Therefore, in order to meet the demands of consumers regarding such sanitary aspects, by the time the water filled in the container reaches the spout of the water server, metal members that may cause rust, It is desirable that there is no rubber member that can propagate various germs, or that the rubber member is reduced as much as possible.

  Therefore, the present invention can be manufactured using a synthetic resin, and when the bottle is filled with a beverage, the beverage in the bottle is placed in the water server when the bottle is further closed. It is a first object to provide a bottle mouth adapter for a beverage server that can be reliably supplied into the server.

  In addition, it is a second object of the present invention to provide a bottle mouth adapter for a beverage server in which a non-spill screw cap that can be applied to a widely used water server can be attached to a 1-2 L plastic bottle that has been commercially available. It is an issue.

  That is, in the present invention, in order to solve at least one of the above-described problems, a bottle mouth adapter for a beverage server for installing a PET bottle in a beverage server, comprising a wall surface to which the mouth portion of the PET bottle is attached. And a second portion having a wall surface to which a non-spill screw cap installed in the beverage server is attached, and is formed in a wall surface forming the first portion. Has a first area where the mouth of the PET bottle is opened, and a second area communicating with the first area is defined in the second portion. The lower end side of this area provides a bottle mouth adapter for a beverage server having an opening.

  The first area is an area partitioned by an inner wall surface to which a mouth portion of a plastic bottle can be attached, and the second area is an area partitioned in an outer wall covering a cap attached to the beverage server. The first area and the second area need to communicate with each other.

  The first portion includes a wall portion on which a mouth portion of various commercially available plastic bottles, which will be described later, can be attached by fitting or screwing. In addition, in the first region partitioned by the wall surface forming the first portion, there is a mouth portion (pour spout) in the plastic bottle, whereby the first region communicates with the internal space of the plastic bottle. Will do.

  In particular, the wall surface of the first region is formed with a screw groove for screwing a screw thread formed in the mouth portion of the plastic bottle on the inner side thereof, and the plastic bottle is screwed into the first region. It is desirable to be able to install it. This is to securely fix the mouth of the plastic bottle. Moreover, when the said wall surface fits the opening part of the said PET bottle, it is desirable to provide fixing members, such as rubber packing, in at least one part of the said 1st area | region. This is because the mouth portion of the fitted plastic bottle is fixed with rubber packing so that it is difficult to come off. Further, since the rubber packing is made of rubber, it is possible to reduce the possibility that the contents of the PET bottle leak out from the connection portion.

  The second portion includes a wall surface on which a non-spill screw cap installed in the beverage server can be attached by fitting or screwing. The second region partitioned inside the second portion is formed to communicate with the first region. The second part is formed, for example, on the outer surface of the wall constituting the second part with a thread groove that is screwed with a thread of a non-spill screw cap to be attached to the beverage server, and is screwed into the non-spill screw cap. Can be combined. By screwing both together, the connection with the non-spill screw cap can be ensured.

  The lower end side of the second region has an opening. And this opening part is obstruct | occluded by connecting a non-spill screw cap to the said 2nd part. That is, the non-spill screw cap has a bottomed cylindrical shape and is installed so as to cover the outer side of the second portion formed in the cylindrical shape, and closes the opening on the lower end side of the second region. A water inlet that rises in an annular shape toward the inside and opens is provided at the center of the bottom surface, and a stopper member is fitted to the water inlet. Since the second area communicates with the first area, it communicates with the internal space of the plastic bottle. And since the opening part provided in the lower end of the said 2nd area | region is obstruct | occluded by the said non-spill screw cap, the connection space of the said PET bottle internal space, a 1st area | region, and a 2nd area | region is The non-spill screw cap is more specifically closed by a lid member that closes the water inlet.

  The water pouring port functions as a pouring port for supplying the contents of the PET bottle that has flowed into the second region into the beverage server. Prior to being connected to the beverage server, the water inlet is closed by a stopper member, and when connected to the beverage server, the water inlet is lifted upward by the water guiding portion of the beverage server to open the contents of the PET bottle. Can be supplied to a beverage server.

  And in the bottle opening adapter for drink servers concerning the said invention, the partition part provided with the communication part which connects both area | regions can be provided between the said 1st area | region and 2nd area | region. It is desirable to form the communicating part in the partition part in such a size or shape that the plug member constituting the non-spill screw cap cannot pass through. However, since the contents of the PET bottle flow down to the second region through the communication portion, the opening diameter of the communication portion is formed to a size that does not hinder the content of the PET bottle from flowing out. The Specifically, the opening diameter of the communication portion is preferably 1 cm to 4 cm, and particularly preferably 2 to 3 cm.

  By providing the partition portion and restricting the opening diameter of the communication portion, the plug member removed during use cannot pass through the communication portion and remains in the second region. It is possible to prevent entry into the first region or the plastic bottle.

  The partition portion may be formed in an inward flange shape between the first region and the second region, and the central opening of the flange may be a communication portion. At this time, the inner diameter of the central opening (communication portion) of the inward flange is formed so that the plug member cannot pass (the inner diameter is smaller than the minimum side of the plug member), so that the plug member is inside the PET bottle. You can prevent it from entering.

  When the flange portion is formed wide, a plurality of openings can be formed in the flange portion, and the openings can be used as communication portions. Furthermore, this partition part can be formed using a mesh or a perforated plate, and can be developed and exist between a 1st area | region and a 2nd area | region. At this time, the mesh hole or opening can function as a communication portion. The partition portion is formed as a beam member having a cross shape, a radial shape, a lattice shape, or the like. The partition member can prevent the passage of the plug member and prevent the plug member from entering the PET bottle. . At this time, it is necessary that the distance between the beam members is set to a size that the plug member cannot pass through. Here, the size through which the plug member cannot pass refers to a size that is less than the size of the minimum side of the plug member provided in a cap mounted on a generally used beverage server. It is desirable that the distance be less than 5 cm, and it is particularly desirable that the distance be less than 1 cm.

  In addition, commercially available PET bottle mouths have various external shapes. Therefore, it is desirable to form PET bottles having different outer diameters so that they can be held in the first portion. For this purpose, the wall surface defining the first region in the first portion is formed so that the inner diameter is gradually increased in the direction away from the second region, or the first region is separated from the second region. It is desirable to form it in a funnel shape with the inner diameter widened in the direction.

  Further, non-spill screw caps of various outer diameters and inner diameters are provided in accordance with the beverage server to be used. Therefore, the outer diameter of the wall surface in the second portion is formed so as to be gradually reduced in the direction away from the second region so that it can be applied to various commercially available non-spill screw caps. Alternatively, it is desirable to form the wall surface in the second portion into a tapered shape with the inner diameter narrowed in a direction away from the second region.

  When the bottle mouth adapter for a beverage server according to the present invention is used with a non-spill screw cap attached to the adapter body, the stopper member in the non-spill screw cap is surely opened when the adapter is installed in the beverage server. It is desirable to configure so that it can be plugged. That is, when the plug member in the non-spill screw cap is fitted to the water injection port from the inside to close the water injection port, in the second region formed in the second part, It is desirable that the height above the water port be higher than the height of the plug member. This is because the plug member that closes the water injection port can be reliably extracted.

  The beverage server can use what is provided to the user by allowing the beverage stored inside or outside to flow down from a predetermined discharge site by opening and closing the stopper by the user's operation. A water server or the like can be used. It is also possible to provide a cooler or a heater inside and cool or heat the beverage.

  The bottle mouth adapter for a beverage server according to the present invention is such that the PET bottle is connected to the first region, and a cap attached to the beverage server is connected to the second region, whereby the PET bottle To supply the beverage server with the contents. The contents of the PET bottle flow down to the second region through the communication portion between the first region and the second region, and the outer wall of the second region and a cap attached to the beverage server Is stored in or passed through a space defined by the bottom surface of the beverage, and is supplied into the beverage server through the water inlet provided on the bottom surface of the cap attached to the beverage server.

  Various types of commonly used plastic bottles can be used as the plastic bottle applicable to the bottle mouth adapter for a beverage server according to the present invention. For example, aseptic filling PET bottles containing water, tea, etc., pressure-resistant PET bottles containing carbonated beverages, heat resistant PET bottles containing fruit juice beverages, hot drinks, etc. can be used. The contents stored in the inside of the PET bottle may be a liquid drink, and for example, water, tea, coffee, fruit juice drink, carbonated drink, or the like can be used.

  The capacity of the PET bottle can be determined as appropriate according to the number of people to be used, the exchange cycle, etc. For example, 120 ml, 500 ml, 1000 ml, 2000 ml, etc. Can be widely used. Moreover, you may use the thing of the capacity | capacitance which is not generally marketed, such as 210 ml, 1500 ml, 2500 ml. Since the bottle mouth adapter according to the present invention can be used in a beverage server by making it possible to attach a PET bottle to a general non-spill screw cap, Although it is a capacity that can be used by a large number of people, it is desirable to configure it as a capacity that does not overload the replacement. Specifically, it is preferably 500 to 3000 ml, and more preferably 1000 to 2000 ml.

  In addition, when using the bottle mouth adapter for a beverage server according to the present invention, the mouth portion of the PET bottle is fitted or screwed to the first portion, the mouth portion of the PET bottle is downward, Invert. For this reason, there exists a possibility that a load may concentrate on the opening part of the said PET bottle. Therefore, in order to reduce the risk of deformation or breakage of the mouth part of the PET bottle or its peripheral part, the PET bottle used for the bottle mouth adapter for the beverage server according to the present invention has its mouth part or its peripheral part. It is desirable that the bending strength of the resin is such that it can withstand the load of the contents of the PET bottle. In addition, it is desirable that the bottle mouth adapter for the beverage server is provided with a support portion that holds the plastic bottle installed in an inverted state. Such a support portion can be formed as an arm provided so as to rise from the adapter body.

  The bottle mouth adapter for a beverage server according to the present invention configured as described above is an injection of a synthetic resin without using a metal member that may cause rust or a rubber member that easily propagates germs. Since it can be created by means such as molding or blow molding, it is possible to store and supply beverages more hygienically than before even when a beverage server is used.

  In addition, the bottle mouth adapter for a beverage server according to the present invention can attach a plastic bottle to the first region formed in the first part, and can be attached to the second region formed in the second part. Since a non-spill screw cap or the like used for a beverage server can be attached, a PET bottle can be used as a container for storing a beverage even in a conventionally provided beverage server. Thereby, even if it is a drink server provided conventionally, the burden of bottle replacement | exchange can be reduced.
