Description

  The present invention relates to a dispensing nozzle with a measuring device that directly pours out the contents contained in a container main body, or accurately measures and dispenses a necessary fixed amount.

  As a prior art for pouring out a certain amount of contents such as liquid detergent and powder detergent, for example, techniques relating to a quantitative stopper as shown in Patent Document 1, Patent Document 2, and Patent Document 3 below have been proposed.

  FIG. 10 is a cross-sectional view showing a quantitative stopper as a conventional example. Each of these prior arts has the same basic structure, and as shown in FIG. 10, a fixed stopper 100 is attached to the opening 111 of the container 110 filled with the contents. The metering plug 100 includes a cup-shaped main body 103 having an inlet 101 and an outlet 102. The cup-shaped main body 103 has a preliminary chamber 105 connected to the inflow port 101 by a partition member 104 and a measuring chamber 106 connected to the discharge port 102 and the preliminary chamber 105.

  When the container 110 is tilted, the contents in the container 110 enter the preliminary chamber 105 in the cup-shaped main body 103 from the inlet 101.

  For example, in the above-described embodiment, the structure in which the dispensing nozzle 10 is attached to the dispensing portion 3a of the lid body 3A of the container-side lid 3 has been described, but the present invention is not limited to the above-described embodiment, The structure directly attached to the mouth tube part 2 of the container main body 1 may be sufficient.

  In addition, the connection portion 12 has been described with a configuration in which the connection portion 12 is screwed to the mouth tube portion 2 by a screw mechanism. However, the present invention is not limited to the above-described embodiment, and the connection portion 12 in the mouth tube portion 2 and the lid main body 3A. Similarly to the configuration, the connecting portion 12 of the dispensing nozzle 10 may be assembled by undercut coupling to the mouth tube portion 2 of the container body 1.

Although the resin material forming the dispensing nozzle 10 is not specifically mentioned in the above embodiment, at least the lid 20, the inner nozzle 13 and the outer nozzle 14 constituting the nozzle body 11 are made of a transparent or translucent resin material. The structure formed by using is preferable. In this configuration, since the state inside the nozzle body 11 can be visually confirmed from the outside, it is easy to adjust the inclination angle of the container body during direct dispensing, or each operation (initial operation) during quantitative dispensing. , Medium-term operation and final-phase operation) can be facilitated, so that the content liquid can be reliably poured out.
The members using the transparent or translucent resin material are not limited to the lid body 20, the inner nozzle 13 and the outer nozzle 14, but the support receiving member 31 and the connecting member 32b constituting the inner plug 34 and the interlocking means 30. Also, it may be configured to be transparent or translucent.

  The pouring nozzle of the present invention achieves selective pouring between direct pouring and quantitative pouring in a state of being mounted on a commercially available container body, and further pursuing high-precision quantitative pouring Applications can be expanded in a wide area.
