Description

  The present invention relates to a liquid dispensing member and a container.

  2. Description of the Related Art Conventionally, in order to pour a liquid such as a medicine contained in a container into an affected area, a plug provided with a nozzle on a mouth of the container is used. Such a nozzle is covered with a cap after its use, but when the cap is removed during the next use, the liquid remaining on the inner wall surface of the nozzle is due to the internal pressure that is higher than the external pressure. There was a case that unintentional ejection was caused by being pushed out.

  In order to solve this problem, a technique described in Patent Document 1 below has been devised. As shown in FIG. 1 of Patent Document 1, the plug fitted to the squeeze container according to the technology includes a fitting cylinder 3 for fitting that fits inside the neck 2 of the container body 1, and fitting for fitting. A straight cylinder-shaped nozzle 5 provided so as to protrude substantially vertically upward from the cylinder 3 and a pouring hole 4 penetrating the nozzle 5 are provided, and the lower end of the nozzle 5 is formed in a slope i.

  According to the spigot described in Patent Document 1, since the nozzle 5 and the extraction hole 4 have a substantially vertical and elongated shape, the liquid adhered to the inner wall surface of the extraction hole 4 in the form of bubbles when the liquid was extracted. However, the bubbles are driven down to the lower end of the nozzle 5 by the outside air flowing into the container body 1 through the extraction hole 4 after the extraction. At this time, the foam that has fallen to the lower end of the nozzle 5 is easily dropped into the container body 1 because the lower end of the nozzle 5 is formed on the inclined surface i, and adheres to the pouring hole 4 and the inner wall surface of the nozzle 5. Therefore, even if the cap 8 is removed at the next pouring, the foamy residual liquid is not pushed out from the pouring hole 4.

  However, even with the technique described in Patent Document 1, the gap is formed between the inner wall surface of the fitting cylinder 3 for mounting (the flange portion) or between the inner wall of the flange portion 3 and the lower end of the nozzle 5. If the liquid remains, there is a possibility that the remaining liquid will enter the pouring hole 4 due to capillary action, and when the cap 8 is removed, there is still a possibility that the liquid that has entered may be ejected by internal pressure. Has been.

The nozzle upper part 5 has a spout 7 for pouring the content liquid from the container, and the nozzle lower part 6 has an inlet 8 for the content liquid from the container to flow in. An internal passage 9 penetrating through the nozzle lower part 6 and the nozzle upper part 5 is formed.

  Referring further to FIG. 1C, the nozzle lower portion 6 is provided on the radially inner side of the flange portion 4, includes a tip portion 11 having a slope 12, and an inlet 8 is formed on the slope 12. . The nozzle lower portion 6 has a columnar portion 10 extending perpendicularly from the lower surface 17 of the base portion 3, and the columnar portion 10 has a side surface 24 and a bottom surface 25, and between the side surface 24 and the bottom surface 25. The edge portion forms a corner portion 13 forming an angle of 90 degrees. Preferably, the bottom surface 25 has the same height as the edge of the flange portion 4, and the tip end portion 11 extends from the bottom surface 25. In this case, the tip end portion 11 protrudes from the flange portion 4. In addition, the internal passage 9 is formed with a narrowed portion 20 whose passage cross-sectional area is smaller than other portions. The narrowed portion 20 is preferably formed at a lower position near the distal end portion 11. More preferably, the narrowed portion 20 is formed from the same height as the bottom surface 25 into the columnar portion 10. The length of the internal passage 9 between the narrowed portion 20 and the spout 7 is preferably as long as possible, and is preferably 5 mm or more, more preferably 10 mm or more.

  Referring to FIG. 1 (d), in this embodiment, the nozzle lower portion 6 extends downward from the position of the lower surface 17 that is deviated from the center of the flange portion 4, thereby a portion having a wide radial interval. 22 and a narrow portion 23 are formed. In the present embodiment, as shown in FIG. 1A, the nozzle upper part 5 also extends from the biased position of the upper surface 16 of the base 3 so as to align with the nozzle lower part 6. In the drawing, the inclined surface 12 of the tip portion 11 of the nozzle lower portion 6 is shown to face the wide portion 22, but the present invention is not limited to this example. It may be formed so as to face in an arbitrary direction at the beginning (the same applies to other embodiments).

  Further, as shown in FIG. 1C, the base portion 3 includes a top portion 14 having an upper surface 16 and a lower surface 17, and a side surface portion 15 depending from the top portion 14, and is formed on the inner wall of the side surface portion 15.

Further, as shown in FIG. 1B, a screw 19 is formed over the outer periphery of the side surface of the nozzle upper portion 5. Furthermore, a liquid breakage portion 21 is provided over the outer periphery of the tip portion of the nozzle upper portion 5.

  FIG. 2 shows a cap 30 that covers the nozzle upper part 5 of the inner stopper 1 of FIG. Referring particularly to FIG. 2C, a screw 31 is formed on the inner wall of the cap 30. In addition, a protrusion 33 is provided on the back surface of the top plate 32 of the cap 30.

  FIG. 3 shows a state in which the inner stopper 1 of FIG. 1 is fitted to the container 40 and the inner stopper 1 is covered with the cap 30 of FIG. In particular, referring to FIG. 3C, a screw 42 is formed on the outer periphery of the side surface of the mouth portion 41 of the container 40, and the flange portion 4 of the inner plug 1 is fitted into the opening portion of the mouth portion 41 of the container 40. In this way, the inner plug 1 can be fitted into the container 40 by screwing the screw 18 of the inner plug 1 with the screw 42 of the container.

  Further, the cap 30 can be attached to the inner plug 1 by screwing the screw 31 of the cap 30 into the screw 19 of the nozzle upper portion 5. At this time, the protruding portion 33 of the cap 30 is inserted into the spout 7 of the nozzle portion 2. Thereby, there is no possibility that the content liquid in the container 40 leaks outside while the cap 30 is attached to the inner plug 1, and the airtightness in the container is maintained.

Next, the operation of the inner plug 1 according to the first embodiment will be described with reference to FIGS. 4 and 5.
Referring to FIG. 4, a state (1) is shown in which the inner stopper 1 is fitted into the container 40 of FIG. In this sideways state (1), the content liquid 43 flows into the inflow port 8 and passes through the narrowed portion 20 by capillary action. However, since the spout 7 is blocked by the projection 33 of the cap 30, air remains in the internal passage 9, and the content liquid 44 that has advanced to the constriction 20 due to this air pressure is retained in the constriction 20. And stay in the internal passage near the inlet 8.

  Next, when the container is placed in the upright state (2) from the sideways state (1), the content liquid gathered in the vicinity of the inner plug 1 in the sideways state (1) falls by its own weight. A certain amount of the content liquid is stuck to the inner wall of the inner plug 1 by surface tension. At this time, referring to FIG. 5, the content liquid collected in the portion 22 having a wide radial interval among the content liquid collected between the nozzle lower portion 6 and the inner wall of the flange portion 4 is moved to the narrow portion 23 by the capillary force. (See the arrow in FIG. 5). Referring to FIG. 4 again, it can be understood that the content liquid 45 that has moved to the narrow portion 23 and has accumulated cannot be tolerated by its own weight and falls. Here, the front end portion 11 where the inflow port 8 is formed protrudes below the end edge of the flange portion 4, and further, a corner portion 13 forming an angle of 90 degrees is formed. Therefore, the inflow port 8 is generated by capillary force. The content liquid gathered in the vicinity can be reduced as much as possible.

  Still referring to FIG. 4, when the cap 30 is removed from the container in the state (2) (3), the spout 7 is released. For this reason, the opening of the expansion force of the air inside the container is generated, and the content liquid accumulated in the constricted portion 20 is pushed out by the action that the internal pressure of the container is made equal to the external pressure, which is indicated by 46 in the state (3). Thus, it moves upward through the internal passage 9.

  In the state (4) after a short period of time from the state (3), the extruded content liquid is repelled before reaching the spout 7 while passing through the long internal passage 9 as shown in 47, and inside the container. Air returns to normal pressure through communication with outside air. Here, the content liquid that has accumulated in the portion 23 having a narrow radial interval has fallen due to its own weight, and even if it remains somewhat, the tip portion 11 where the inflow port 8 is formed is a ridge portion. 4, which protrudes downward from the end edge 4 and is formed with a corner 13 that forms an angle of 90 degrees, the residual liquid is reduced from the vicinity of the inlet 8 when the cap 30 is removed. Sometimes the residual liquid can be more effectively prevented from being ejected.

As described above, in the present embodiment, it is possible to prevent the content liquid from being ejected when the cap 30 is removed.
The liquid contained in the container 40 includes dental adhesives such as dental bonding materials, dental pretreatment agents such as dental primers, denture base materials such as immediate polymerization resins and lining materials, and dental use. There are lubricants, dental etching materials, dental cleaning materials, dental materials such as dental drugs, medical adhesives, drugs and industrial adhesives, drugs. It is not limited.
