Description

  The present invention relates to a pouring nozzle that pours out the contents contained in a container body as it is, or accurately measures and pours out a predetermined 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. 12 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. 12, the metering 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. At the same time, a certain amount of contents held in the measuring chamber 106 are discharged from the discharge port 102. Thereafter, when the container 110 is returned to the original posture, the contents in the preliminary chamber 105 are transferred to the measuring chamber 106, but excess contents exceeding the volume of the measuring chamber 106 are returned from the inlet 101 into the container 110. It will be. Thereby, it is possible to always discharge a certain amount of contents.

  However, the conventional prior art has a package configuration in which the metering plug 100 is integrally provided in the container 110 in advance, and the metering plug 100 is discarded together with the container 110 after the contents are used up. There is a problem that the effective utilization of resources is low.

  In the conventional prior art described above, since it is necessary to provide the metering plug 100 inside the container 110, the internal volume of the contents that can be accommodated in the container 110 is reduced accordingly, or the same internal volume is reduced. In order to ensure, there is a problem that the outer shape of the container 110 has to be enlarged.

  Further, the conventional prior art has a configuration in which only a certain amount of contents can be always poured out. For this reason, for example, when the content is a liquid detergent or a powder detergent, the washing machine tub has a constant volume, so that it is preferable that the amount of detergent can be adjusted according to the amount of laundry, The conventional prior art has a problem that it is difficult to adjust and dispense an amount of detergent according to taste.

  Furthermore, in the above conventional prior art, depending on the inclination angle of the container 110, the contents that have entered the spare chamber 105 in the cup-shaped main body 103 overflow from the inlet 101, overflow the partition member 104, and continue to the outlet. 102 may be discharged. As a result, there is a problem that the volume of the contents to be dispensed in a quantitative manner varies depending on the inclination angle of the container 110, that is, there is a problem that the accuracy of the quantitative dispensing is likely to be lowered.

  In order to solve the above-described problems in the prior art, the present invention can prevent the container body from being freely attached to and detached from the mouth tube portion and reducing the capacity that can be accommodated, and the contents are directly poured out. It is an object of the present invention to create a dispensing nozzle capable of performing a high-precision dispensing of a certain amount of contents.

Of the means for solving the above problems, the main configuration of the present invention is as follows.

  Further, in the main configuration of the present invention, when the first plug closes the spout on the lid, the inner nozzle is closed by the second plug, and when the second plug closes the inner nozzle, the spout by the first plug is opened. In addition to the provision of interlocking means for releasing the blockage, the contents are moved from the container body through the inner nozzle to the preliminary chamber and the measuring chamber, and from the preliminary chamber and the measuring chamber to the outside through the spout. Since the dispensing can be performed appropriately, the quantitative dispensing can be performed reliably and with high accuracy.

  Further, in the above-described configuration of the present invention, the interlocking means is provided with a first plug at one end and a second plug at the other end and a swingable connecting member, and a pivot shaft for swinging the connecting member. And a support receiving member that pivotally supports the rotating shaft, a simple structure such as a so-called seesaw mechanism allows a preliminary chamber for contents from the container body through the inner nozzle and It is possible to selectively realize the movement to the weighing chamber and the dispensing from the spare chamber and the weighing chamber to the outside through the spout.

  Further, in the above configuration of the present invention, a support piece is formed on the top wall of the second plug, a long hole is provided in one of the support piece and the connection member, and a connection shaft inserted through the long hole is movably inserted in the other. In the configuration in which the second plug and the connecting member are connected so as to be interlocked with each other, the movement of the connecting portion between the second plug and the connecting member can be made smooth. Therefore, the inner nozzle can be reliably poured out and closed.

  In addition to the above configuration, in the configuration in which setting means for setting both the spout by the first plug and the inner nozzle by the second plug to a half-open state is provided, the content is directly poured out with the lid closed. And in particular, a small amount of contents can be directly dispensed.

  In addition to the above configuration, the setting means is configured by adding a connecting shaft that is movable in the long hole and a pair of convex ribs that are formed at a predetermined interval on the lower edge of the long hole. Since the setting means can be configured with a simple configuration, the manufacturing cost can be reduced. In addition, the occurrence of defects can be suppressed to a low level, and maintenance can be easily performed even if a defect occurs.

  In addition to the above configuration of the present invention, the second plug and the connecting member are made of synthetic resin, and the two are integrally connected via a support piece having a thin bent portion. Since the smooth operation of the connecting portion between the second stopper and the connecting member can be ensured, the forward and backward movement of the second stopper becomes appropriate, so that the inner nozzle can be reliably poured out and closed. Further, since the second stopper and the connecting member can be formed by integral molding, the cost can be reduced.

Can remain (mid-term operation).

  And the 1st stopper 22 is lifted and the spout 21 is set to a fully open state. At this time, the second plug 23 is interlocked via the interlocking means 30, and the inner nozzle 13 is set in a closed state. As shown in FIG. 8, subsequently, by tilting the container body 1 into an inclined posture, a certain amount of contents 40 remaining in the measuring chamber 16 can be poured out through the spout 21. (Final operation).

  As described above, in the dispensing nozzle 10 of the present invention, since the fixed amount of the contents 40 from the spout 21 can be discharged with the inner nozzle 13 closed, the container at the time of quantitative dispensing as in the prior art is used. A problem that the contents 40 on the main body 1 side are poured out together can be prevented. Therefore, in the present invention, it is possible to always perform quantitative dispensing of the contents 40 with high accuracy without being affected by the inclination angle of the container body 1.

  In the state shown in FIG. 1A, that is, when the spout 21 is closed with the first plug 22 and the inner nozzle 13 is opened with the second plug 23, the bent portions 23b and 23b are bent and deformed, and the connecting member 31 and the support piece The space between 23a and the top wall of the second plug 23 contracts in a substantially Z shape.

  On the other hand, in the state shown in FIG. 2, that is, in a state where the first plug 22 closes the spout 21 and the second plug 23 closes the inner nozzle 13, the bent portions 23 b and 23 b are extended and deformed. The support piece 23a extends between the top wall and the connecting member 31.

  Thus, in the third embodiment, the connecting portion (bending portion 23b, 23b) between the second plug 23 and the connecting member 31 is bent or extended depending on the situation, and the first plug 22 and the second plug are thus deformed. 23 smooth linkages can be achieved. For this reason, it becomes possible to make the advancing and retreating movement of the second plug 23 according to the opening and closing of the first plug 22 smooth, so that the inner nozzle 13 can be appropriately opened and closed and poured out.

  As mentioned above, although the structure of this invention and its effect were demonstrated along the Example, embodiment of this invention is not limited to the said Example.

  For example, in the above-described embodiment, the first plug 22 and the second plug 23 are connected and connected via the interlocking means 30. However, the present invention is not limited to this, and the first plug The stopper 22 and the second stopper 23 are not necessarily linked to each other, and the operation of the first stopper 22 closing the spout 21 and the operation of the second stopper 23 closing the inner nozzle 13 are independent from each other. It is also possible. However, as described in the first to third embodiments, when the first stopper 22 and the second stopper 23 are configured to be interlocked, the opening and closing timings of the inner nozzle 13 and the spout 21 are adjusted. This is preferable in that an operation error at the time of quantitative dispensing can be prevented.

  In the first to third embodiments, the case where the lid 20 is completely removable from the outer nozzle 14 has been described. However, the lid 20 is connected to the outer nozzle 14 via a hinge. It is good also as a structure to be made.

  Further, in the first to third embodiments, the configuration in which the connection portion 12 and the mouth tube portion 2 on the container body 1 side are screwed and connected has been described. However, the embodiment of the present invention is described in the above embodiments. It is not limited to this, but a locking projection is formed on one of the connecting portion 12 and the mouth tube portion 2 on the container body 1 side, a locking recess is formed on the other, and both are engaged so that It is also possible to adopt a configuration in which cut coupling is performed.

  The dispensing nozzle of the present invention is a field of dispensing nozzles in which a metering chamber and a spare chamber are formed in the nozzle portion, and selective dispensing of direct dispensing and quantitative dispensing and pursuing high-precision quantitative dispensing are pursued. Can be used in a wider area.
