Description

  The present invention relates to a cap for liquid injection container.

  In the case of the pouring container which accommodates and dispenses the seasoning etc., the whole pouring container is inclined and pouring is performed from a nozzle opening. When the filling container is returned to the upright position after filling, dripping of the contents from the nozzle opening may occur. Poor drainage at the nozzle opening and residual contents in the nozzle are the causes of dripping.

  In order to improve drainage from the nozzle opening after pouring, a liquid pouring cap provided with a guide groove in the nozzle has been proposed (see, for example, Patent Document 1).

  In the liquid pouring cap of Patent Document 1, even if there is residual liquid in the nozzle, it is led into the guide groove by capillary action. The residual liquid introduced into the guide groove is configured to be able to drip into the container from its lower end opening by its own weight. By this, it is intended to reduce the liquid dripping from the nozzle opening.

Japanese Patent Application Laid-Open No. 8-24106

  However, in the case of Patent Document 1 described above, all residual liquid in the nozzle is not necessarily guided to the guide groove and dripped into the container. Although the liquid dripping from the nozzle opening is reduced, a part of the residual liquid may remain inside the nozzle or in the middle of the guide groove. Such liquid residue drips to the outside from the nozzle port and causes contamination of the outer surface and the periphery of the container. If the residual liquid in the nozzle solidifies with the passage of time, the pouring of the contents is impeded and the original function is lost.

  It is expected that occurrence of such a situation can be avoided if liquid dripping from the nozzle opening after pouring is prevented and moreover the liquid residue in the cap can be reduced as much as possible.

  Therefore, an object of the present invention is to provide a cap for a pouring container which can prevent liquid residue in addition to dripping after pouring.

  The injection container cap according to the present invention comprises a cap body attached to the mouth of the container body, and is a liquid injection container cap for injecting a liquid, wherein the liquid passing through the cap body is formed. A hole, a liquid injection nozzle provided on the cap body so as to protrude to the outside of the liquid flow hole, a liquid contact portion formed to protrude toward the liquid flow hole inside the cap body, and the liquid flow And a liquid introducing portion provided along the inner side surface of the cap body connected to the hole.

  According to the present invention, the cap for liquid injection container has the liquid contact portion protruding inside the liquid flow hole of the cap body, so that the liquid moved inward from the liquid injection nozzle after liquid injection is the liquid contact Contact the department. Furthermore, in the cap body, since the liquid introduction portion is provided along the inner side surface connected to the liquid passage hole, the liquid passing through the liquid passage hole and in contact with the liquid contact portion is led to the liquid passage portion.

  As described above, the liquid remaining in the liquid injection nozzle after the liquid injection contacts the liquid contact portion, is guided to the liquid introduction portion, and moves from the inside of the liquid injection nozzle, so that liquid drip is prevented. The liquid introduction portion assists the movement of the liquid remaining in the liquid injection nozzle into the container body. The liquid can smoothly move in the liquid introduction portion and return to the inside of the container body, and the liquid injection container cap of the present embodiment can also prevent liquid remaining.

A liquid contact portion 32 a is formed on the inner side of the cap body 16 so as to protrude toward the liquid passage hole 24. A region along the inner side surface of the cap main body 16 connected to the liquid flow hole 24 becomes a liquid introduction portion 40 for moving residual liquid (not shown) in the liquid injection nozzle 22 to the container main body 12 after liquid injection. .

  It is preferable that the liquid introducing portion 40 be formed to be able to exhibit capillary action in order to assist the transfer of the residual liquid into the container body 12. The liquid introduction portion 40 is a gap between the inner side surface 20 a of the liquid injection portion 20 connected to the liquid passage hole 24 and the liquid introduction plate 32 formed on the top portion 34 of the connection portion 30. By appropriately setting the width and length of the gap, the material of the cap body 16 and the like according to the type of the content stored in the container body 12, the capillary phenomenon can be manifested in the gap. The liquid contact portion 32 a guides the residual liquid of the liquid injection nozzle 22 after liquid injection to the liquid introduction portion 40.

  As shown in FIG. 3, the liquid injection nozzle 22 in the liquid injection unit 20 is provided upward. The angle θ of the upper inner peripheral surface 22b of the liquid injection nozzle 22 with respect to the horizontal plane is preferably about 5 to 45 ° although it depends on the length of the liquid injection nozzle 22 and the type of contents contained in the container body 12 . The upper part of the liquid injection nozzle 22 in the present embodiment protrudes outward, so the nozzle port 22a which is the opening end of the liquid injection nozzle 22 is inclined so that the upper part is outside the lower part in the longitudinal cross section. By forming the nozzle opening 22a in this manner, not only liquid injection but also liquid dripping after liquid injection can be prevented.

  The diameter of the liquid passage hole 24 can be appropriately selected according to the upward angle of the upper inner peripheral surface 22 b of the liquid injection nozzle 22, the type of contents, and the like. An air intake hole 26 is formed at the top of the liquid injection portion 20. At the lower part of the liquid injection portion 20, a receiving groove 28 is provided circumferentially along the outer edge. The receiving groove 28 serves as a connecting female part for inserting and connecting the protrusion 36 as the connecting male part in the connecting part 30.

  As shown in FIG. 4, in the connecting portion 30, the liquid guiding plate 32 is formed upright from the top portion 34. The liquid guide plate 32 has a rectangular shape in which the longitudinal direction is the longitudinal direction. The inner peripheral side of the liquid guide plate 32 is flat, but the outer peripheral side of the liquid guide plate 32 is inclined at the upper part. Thus, the liquid guide plate 32 is configured such that the thickness on the tip end side is reduced. In the cap 14 of the present embodiment, the tip end side of the liquid guide plate 32 is a liquid contact portion 32 a that protrudes toward the inside of the liquid passage hole 24. A protrusion 36 as a connecting male portion is circumferentially provided on the outer edge of the top portion 34 of the connecting portion 30. By connecting the connection part 30 and the liquid injection part 20, the cap 14 of this embodiment as shown in FIG. 2 is comprised.

  When connecting the connection portion 30 and the liquid injection portion 20, first, the upper end of the connection portion 30 is inserted so as to cover the liquid injection portion 20. Next, the projection 36 as the connecting male portion and the receiving groove 28 as the connecting female portion are fitted. The connection portion 30 and the liquid injection portion 20 are connected by pushing the protrusion 36 into the receiving groove 28 until the outer peripheral upper end 30a of the connection portion 30 and the outer peripheral lower end 20b (see FIG. 3) of the liquid injection portion 20 abut. And integrated.

  At this time, the position in the circumferential direction of the connection portion 30 and the liquid injection portion 20 may be aligned with a predetermined position by the positioning means. As the positioning means, for example, display portions (not shown) provided respectively at predetermined positions on the lower end outer peripheral edge of the connection portion 30 and the liquid injection portion 20 can be used. After positioning in the circumferential direction so that the display units are aligned, the connection unit 30 and the liquid injection unit 20 are connected. Thus, the liquid contact portion 32 a in the connection portion 30 can be held at a predetermined position with respect to the liquid passage hole 24 in the liquid injection portion 20. The cap 14 can be screw-fitted to the opening of the container body 12 by means of a threaded portion 42 formed on the inner peripheral surface of the lower portion of the connecting portion 30.

  FIG. 5 shows a longitudinal sectional view of the cap 14 from another direction. As shown in FIG. 5, the liquid contact portion 32 a on the tip side of the liquid guide plate 32 is provided so as to overlap an area around the lower half of the liquid passage hole 24 provided in the cap main body 16. It is preferable that the width w of the liquid guide plate 32 be about 20 to 200% of the diameter of the through hole 24. It is preferable to provide the liquid guide plate 32 so that the upper end of the liquid contact portion 32 a reaches the vicinity of the center in the height direction of the liquid passage hole 24. By providing such a liquid introduction plate 32, it is possible to introduce the residual liquid after injection to the liquid introduction portion 40 without interfering with the liquid injection from the liquid injection nozzle 22.

(Operation and effect)
The cap 14 for liquid injection containers comprised as mentioned above is mounted | worn with the opening part of the container main body 12 in which the contents 44, such as a liquid, were accommodated, as shown to FIG. 6A. When the contents 44 are poured out, the entire liquid injection container 10 is inclined in the direction of arrow A. The contents 44 in the container main body 12 pass from the inside of the cap main body 16 through the liquid passage hole 24 and are ejected from the liquid injection nozzle 22 provided on the cap main body 16 so as to protrude outside the liquid passage hole 24. .

  As shown in FIG. 6B, the liquid injection from the liquid injection nozzle 22 can be stopped by raising the entire liquid injection container 10 in the direction of the arrow B. Although the contents 44 basically return into the container body 12, a part of the contents 44 may remain in the liquid injection nozzle 22 as a residual liquid 44a. The liquid contact portion 32 a is formed to project inside the cap main body 16 toward the liquid flow hole 24, so the liquid level of the residual liquid 44 a toward the inside of the cap main body 16 is provided inside the liquid flow hole 24. The liquid contact portion 32a is contacted.

  As described above, the liquid contact portion 32 a in the present embodiment is on the tip side of the liquid guide plate 32. Therefore, when the liquid surface contacts the liquid contact portion 32 a, the residual liquid 44 a can be drawn to the liquid guide plate 32 and can move along the liquid guide plate 32 toward its proximal end. Here, the residual liquid 44 a is moved by the liquid introduction portion 40 formed of a gap between the inner side surface 20 a of the liquid injection portion 20 and the liquid introduction plate 32 connected to the liquid passage hole 24. The liquid introduction portion 40 is formed along the inner side surface of the cap body 16 so as to be able to exhibit capillary action. By providing such a liquid introducing portion 40, the residual liquid 44a smoothly moves in the liquid introducing portion 40 and is collected in the container main body 12.

  As shown in FIG. 6C, when the liquid injection container 10 is further raised in the direction of arrow B and returned to the upright posture, the residual liquid 44a moved from the liquid injection nozzle 22 to the liquid introduction portion 40 is contained in the container body 12. Fall down. By providing the liquid contact portion 32 a in the cap main body 16, substantially all of the residual liquid 44 a in the liquid injection nozzle 22 can move to the liquid introduction portion 40. For this reason, the liquid dripping from the nozzle opening 22a is avoided, and the liquid residue in the pouring nozzle 22 is also prevented. Moreover, since the liquid introducing portion 40 assists the movement of the residual liquid 44 a into the container body 12, substantially all of the residual liquid 44 a in the liquid introducing portion 40 can move into the container body 12. . Thus, the cap 14 of the present embodiment can prevent liquid residue in addition to liquid dripping after liquid injection.

  In the liquid filling container equipped with the conventional cap, when the liquid filling container is returned to the upright position after the liquid filling, it is not possible to prevent the liquid remaining in the liquid filling nozzle of the cap. As shown in FIG. 7A, even in the case of the liquid injection container 110 in which the conventional cap 114 is attached to the opening of the container body 112, the liquid injection nozzle is raised by raising the entire liquid injection container 110 in the arrow B direction after liquid injection. Pouring from 122 can be stopped. At this time, although the content 144 basically returns into the container body 112, a part of the content 144 remains in the vicinity of the nozzle opening 122a of the liquid injection nozzle 122 in the liquid injection cap 114 as a residual liquid 144a. .

  As shown in FIG. 7B, when the filling container 110 is further raised in the direction of arrow B and returned to the upright posture, the residual liquid 144a remaining in the filling nozzle 122 of the cap 114 moves into the container body 112. There is no. The residual liquid 144a in the pouring nozzle 122 drips to the outside from the nozzle port 122a and causes the outer surface and the periphery of the pouring container 110 to be contaminated. In addition, when the residual liquid 144a in the liquid injection nozzle 122 is dried and solidified, the liquid injection from the liquid injection nozzle 122 is hindered.

  The cap 14 of the present embodiment can prevent liquid residue in the cap 14 in addition to liquid dripping from the nozzle port 22 a after liquid injection, and therefore residual liquid 144 a in the liquid injection nozzle 122 as in the prior art. It is possible to avoid the problems caused by
