Description

  The present invention relates to a container capable of distinguishing and confirming the contents of a container when the contents are poured out from a flexible container using a suction type dispensing device, and an automatic suction type dispensing. It relates to the device.

  Conventionally, as a business-use liquid container or powder container for dispensing contents using an automatic suction type dispensing device, for example, there is a bag-in-box. This bag-in-box consists of an outer box made of cardboard and a flexible inner container with a cap attached to the container body made of film, and the inner container filled with the contents is stored in the outer box. Met. The spout is composed of a spout (pouring member) heat-sealed at the pouring position of the inner container and a cap. When the contents are poured out of the container, the spout protruding from the outer box, the outer box Remove the cap of the spout from the spout or the spout outlet of the spout and insert the tip of the spout nozzle of the automatic suction-type spout device, The positioning receiving portion of the pouring nozzle is hooked on the spout's positioning brim and fixed, and the contents are sucked out by the pump.

  However, containers of the same shape and size may be used for various contents, and when used, the automatic suction type dispensing device is mistakenly attached to a container filled with other contents In such a case, it was very difficult to clean the flow path such as the nozzle of the automatic suction type dispensing device. Even if the inner diameter of the spout of the container is slightly different from the size of the tip of the dispensing nozzle of the automatic suction type dispensing device, the tip of the spout dispensing hole has a tapered portion, and the tip of the dispensing nozzle If it is pushed firmly into the tip of the pouring hole, it may be inserted, and other contents may be mispoured.

  The present invention solves the problem when the contents are poured out from the container with the above-described conventional automatic suction type dispensing apparatus, and when the contents are poured out from the container using the suction type dispensing apparatus. Furthermore, the present invention provides a container and an automatic suction-type dispensing device that can identify and confirm the contents of a container and can distinguish the contents to be dispensed without making a mistake.

That is, according to the first aspect of the present invention, in a container in which a rigid thermoplastic resin spout is heat-sealed at a pouring position of a flexible container body made of a film, a conductive portion is electrically connected to a predetermined portion of the spout. It is a container whose contents can be discriminated depending on whether or not a predetermined portion of the surface of the spout is electrically conductive, which is formed integrally with another thermoplastic resin portion.

  And when 2nd invention of this invention is connected to the spout of the container which can distinguish the content as described in 1st invention, a some electroconductive contact contact | abuts to the predetermined position on the surface of a spout. The automatic suction type dispensing device is capable of discriminating the contents of the container, wherein the contents of the container are discriminated based on whether or not the plurality of conductive contacts are conductive.

In order to pour out the contents, when the automatic suction type dispensing device according to the present invention is connected to the spout of the container capable of identifying the content of the present invention, the automatic suction type dispensing device is dispersed. A plurality of conductive contacts arranged in contact with the surface of the spout. A predetermined portion of the spout of the container is formed integrally with another thermoplastic resin portion using a conductive thermoplastic resin in order to show the contents. The plurality of conductive contacts abut on a portion of the conductive thermoplastic resin or another thermoplastic resin portion. As a result, electrical conduction is possible between the conductive contacts that are in contact with the conductive thermoplastic resin portion, but the conductive contacts that are in contact with the conductive thermoplastic resin portion and the other thermoplastic resin portions. No electrical conduction between adjacent conductive contacts. Moreover, it does not conduct between the conductive contacts in contact with other thermoplastic resin portions. The contents of the container can be discriminated based on the difference in conductivity between the conductive contacts. As a result, it is possible to prevent the contents to be poured out from being mistakenly poured out.

  Next, embodiments of the container and the automatic suction type dispensing apparatus according to the present invention that can distinguish contents will be described in detail with reference to the drawings.

  The container and the automatic suction-type dispensing device according to the present invention are automatic suction-type dispensing devices, for example, from a flexible container that is an inner container of a bag-in-box, to another container. When dispensing, especially when continuously dispensing, the contents are prevented from being accidentally poured out from different containers.

  First, the container whose contents can be distinguished is a flexible container body made of a single-layered, multilayered or superposed film, at least half of which is soft, and a spout protruding from a spout mounting hole of the container body The spout is composed of a spout that protrudes to the pouring position of the container body and is heat-sealed, and a cap that is attached to the spout. And the predetermined part of a spout is shape | molded integrally with the part of another thermoplastic resin using a conductive thermoplastic resin. As this molding method, a multicolor injection molding method is used, but an insert injection molding method using a conductive thermoplastic resin sheet may be used. Further, if necessary, the appearance can be improved by making the conductive thermoplastic resin portion and the other thermoplastic resin portion the same color.

  Next, when the automatic suction type dispensing device (60) capable of distinguishing the contents is connected to the spout (10) of the container capable of distinguishing the contents, for example, as shown in FIG. A plurality of conductive contacts (61) are disposed so as to abut the portion. Therefore, when connected to the spout of the container capable of discriminating the contents, the plurality of conductive contacts come into contact with the conductive thermoplastic resin portion or other thermoplastic resin portions. Then, the electric conductivity between the conductive contacts is measured by an ammeter (62) or a resistance measuring device, and the contents of the container are discriminated by the difference in the electric conductivity.
