Description

  The present invention relates to a support for a cartridge container for a beverage dispenser that supports a flexible cartridge container that is connected downward to the beverage dispenser.

  Some cartridge containers used for beverage dispensers such as drinking water and juice have flexibility by forming a thin side wall portion to provide flexibility (see, for example, Patent Document 1). In the device described in Patent Document 1, when filling a cartridge container with a beverage, a ridge or a circumferential groove is provided on the outer periphery of the tube opening so as to support the cartridge container with the tube opening facing upward. This flexible cartridge container can be efficiently transported by folding an empty container, and at the time of use it shrinks due to atmospheric pressure as the filled beverage falls, and air does not flow into it, so that bacteria in the air There is an advantage that it is not polluted by etc.

  Such a flexible cartridge container is connected to a container connecting portion provided on the upper surface of the beverage dispenser with a cylindrical mouth portion for discharging a filled beverage facing downward, and a flexible side wall portion is provided. A frame-shaped support is placed on the upper surface of the beverage dispenser so as not to fall down, and the side wall portion around the cartridge container is supported (for example, see Patent Document 2). The support for the cartridge container for beverage dispenser described in Patent Document 2 is provided with a receiving portion for receiving a shoulder portion around the cylindrical mouth portion of the cartridge container at a lower portion inside the wall frame that supports the circumference of the cartridge container. Is connected to the container connecting portion of the beverage dispenser.

  Some of the flexible cartridges described above have flexibility by forming not only the side wall portion but also the shoulder portion around the tube opening portion to be thin. Many of the shoulder portions are formed in a shoulder shape with a heel that descends toward the side of the surrounding side wall. In addition, since the cylinder mouth portion can secure a certain degree of rigidity depending on its shape, in some cartridge containers made of PET (polyethylene terephthalate) or the like, the tube mouth portion is also formed thin.

  Even if the beverage in the container flows out, air does not flow into the flexible cartridge container. Therefore, when the beverage in the container decreases, the rigidity of the side wall portion contracted so as to be folded increases, and the side wall further increases. The part does not shrink and the inside of the container becomes negative pressure.

  At this time, as shown in FIG. 6, the flexibility that is supported downward by the receiving portion 3 of the frame-like support 1 placed on the upper surface of the beverage dispenser 21 and that gives the shoulder portion 13 flexibility. The cartridge container 11 has a problem that the flexible shoulder 13 is recessed inward due to the negative pressure in the container, and the tube opening 12 is lifted. When the shoulder portion 13 has a shoulder shape with a heel that descends and slopes toward the side wall portion 14, the amount of lifting of the tube opening portion 12 becomes larger. Thus, when the cylinder mouth part 12 floats, it will come off from the container connection part 22 of the connected drink dispenser 21, and the drink which falls from the cylinder mouth part 12 will leak outside.

  Therefore, the problem of the present invention is that the beverage in the flexible cartridge container having flexibility at the shoulder portion is reduced, and the container is connected to the container connection portion of the beverage dispenser even if the inside of the container becomes negative pressure. This is to prevent the tube opening from floating.

  In order to solve the above-mentioned problems, the present invention supports the periphery of a flexible cartridge container having a cylindrical mouth part downwardly connected to a container connection part on the upper surface of a beverage dispenser and having flexibility in a shoulder part. In a support for a beverage dispenser cartridge container provided with a receiving portion for receiving a shoulder around the cylindrical mouth portion of the cartridge container at the inner lower portion of the wall frame, on the lower side of the receiving portion, A configuration is provided in which means for locking the downward movement of the downward cylindrical mouth portion of the cartridge container is provided.

  By providing a slide guide portion that slides the insertion member inserted from the lateral direction in the lateral direction on both the left and right sides of the bifurcated portion, the insertion member can be stably inserted into the upper side of the flange on both sides of the tube opening. it can.

  By providing springs pressed against the slide guide portions on both the left and right sides of the insertion member, the insertion member inserted on the upper side of the flange can be fixed without rattling.

  By attaching a rod-like handle that protrudes to the outside of the wall frame to the insertion member, the insertion member disposed on the lower side of the receiving portion can be inserted from the outside of the wall frame.

  By making the rod-like handle detachable from the outer side of the wall frame to the insertion member, the insertion member can be easily assembled below the receiving portion by removing the handle.

  By making the rod-like handle attachable to and detachable from the insertion member with a screw, the rod-like handle can be easily attached to and detached from the insertion member from the outside of the wall frame, and the handle does not fall off when the insertion member is subtracted. Can be.

  The support device for the cartridge container for beverage dispenser of the present invention comprises means for locking the upward movement of the downward cylindrical mouth portion of the cartridge container on the lower side of the receiving portion receiving the shoulder portion around the cylindrical mouth portion of the cartridge container. Even if the beverage in the flexible cartridge container with softness in the shoulder portion is reduced, the cylinder mouth portion does not rise due to the indentation of the shoulder portion due to the negative pressure in the container. In addition, the tube opening portion can be prevented from being detached from the container connection portion of the beverage dispenser.
