Description

[0001]
[Industrial application fields]
The present invention relates to a liquid pouring cap used when pouring liquid contents from a bottle, and more particularly to a liquid pouring cap capable of preventing contamination of a bottle pouring outlet.
[0002]
[Prior art]
In the liquid dispensing cap attached to the mouth of the bottle, when the bottle is tilted to pour out the highly viscous liquid contents such as oil, sauce, ketchup, etc. It is well known that the contents of the dispensing nozzle may leak and stain the cap body and the side of the bottle. The cause of this liquid leakage is that the liquid content at the tip of the pouring nozzle when the bottle tilts back after pouring remains without returning to the inside of the bottle, and the outer surface of the pouring nozzle Because it flows down along the line.
[0003]
In order to solve this liquid leakage phenomenon, the dispensing nozzle is configured to be able to advance and retract inside and outside the guide cylinder, and after dispensing the liquid content, the dispensing nozzle is retracted into the guide cylinder to It is also conceivable to prevent the liquid leakage by covering the tip portion of the pouring nozzle to which the remaining portion is adhered with a guide tube (see Japanese Patent Application Laid-Open No. 11-70960).

[0007]
【Example】
The details of the present invention will be described below with reference to the drawings showing an embodiment.
1 to 3, reference numeral 1 denotes a container cap. The container cap 1 has a cap body 2 and a cover cap 3. The cap body 2 can be attached to the mouth 5 of the container 4 with screws 6, and the cover cap 3 can open and close the upper end of the cap body 2. Although the cap body 2 and the cover cap 3 may be configured separately, in this embodiment, the cap body 2 and the cover cap 3 are connected by a hinge 9 to form a hinge cap. The hinge 9 is formed as a thin wall capable of bending a resin material. In the cap body 2, a partition plate 7 is provided in the vicinity of the upper end so as to cross the internal space 11 perpendicularly to the central axis 8, and the pouring nozzle 12 projects outward from the partition plate 7 along the direction of the central axis 8. Yes.
[0008]
A cylindrical sleeve 13 is slidably fitted on the outside of the nozzle 12. The length of the sleeve 13 in the direction of the central axis 8 is substantially the same as the protruding height of the nozzle 12. The sleeve 13 can move forward and backward in the direction of the central axis 8 by sliding, and covers and covers the upper end 14 of the nozzle 12 in the advanced position advanced upward, and the upper end in the retracted position retracted downward. 15 almost coincides with the upper end 14 of the nozzle 12 and exposes the upper end 14 thereof. A drive lever 16 is disposed on the partition plate 7 of the cap body 2. As shown in FIGS. 4 and 5, the drive lever 16 has a substantially long plate shape. As shown in FIGS. 4 and 5, the shaft 18 constituting the fulcrum 19 of the drive lever 16 is extended, and the tip 21 is on the left. The portion 21a and the right portion 21b are bifurcated, and the rear end is bifurcated vertically, and an upper pulling portion 31 and a lower pressing portion 32 are provided. The length of the pulling portion 31 is slightly shorter than the length of the pressing portion 32. Engagement protrusions 23 are formed inside the left part 21 a and the right part 21 b, and engagement recesses 24 are formed on the outer surface of the sleeve 13. The engagement protrusions 23 are formed in the engagement recesses 24. By inserting, the drive lever 16 and the sleeve 13 are connected, and as the tip 21 swings around the fulcrum 19, the sleeve 13 moves up and down from the advanced position to the retracted position. A pair of support frames 33 are erected on the partition plate 7 of the cap body 2, and a bearing portion 34 is provided at the upper end thereof. The shaft rod 18 of the drive lever 16 is rotatably fitted in the bearing portion 34, so that the drive lever 16 is swingably supported by the support frame 33. On the other hand, a cylindrical stopper plug 25 projects from the inner surface of the top plate 35 of the cover cap 3. The stopper plug 25 is inserted into the upper end of the sleeve 13 when the cover cap 3 closes the upper surface of the cap body 2 to close the upper end opening of the sleeve 13.
[0009]
Next, operation | movement of the container cap 1 comprised in this way is demonstrated.
As shown in FIG. 6A, when the first cover cap 3 closes the cap body 2, the pressing piece 26 of the cover cap 3 pushes down the pressing portion 32 at the rear end of the drive lever 16 to the bottom. Therefore, the tip 21 on the opposite side of the drive lever 16 is raised, and the sleeve 13 is pushed up to the uppermost position. In this state, the sleeve 13 is in a state of covering and covering the upper end 14 of the nozzle 12 serving as a liquid content outlet, and a stopper plug 25 is inserted into the upper end of the sleeve 13. Even if the liquid content adheres to 12, the upper end 14 which becomes a spout does not get dirty.
[0010]
Next, when the cover cap 3 is opened to pour out the liquid contents, the pressing piece 26 of the cover cap 3 starts to pull up the pulling portion 31 of the drive lever 16, and the tip 21 of the drive lever 16 begins to descend. And the stopper plug 25 of the cover cap 3 comes off from the sleeve 13 (FIG. 6B). Further, as the degree of opening of the cover cap 3 is further increased, the sleeve 13 is gradually lowered (FIG. 6C), and finally the lower limit position, that is, the upper end of the nozzle 12 and the upper end of the sleeve 13 are flush with each other. Or the second position where the upper end of the sleeve 13 is slightly above the upper end of the nozzle 12 and the upper end of the nozzle 12 is almost exposed (FIG. 6D). In this state, the pulling portion 31 at the rear end of the drive lever 16 is slightly above the horizontal position and does not interfere with the pressing piece 26 of the cover cap 3 or comes to a position where the interference can be removed by elastic deformation of the material. The engagement between the piece 26 and the pulling portion 31 is released, and the cover cap 3 can be opened largely (FIG. 6C). In this state, the container 4 can be tilted and the liquid content can be poured out from the nozzle 12. When pouring is completed and the cover cap 3 is closed, the sleeve 13 covers and encloses the upper end of the nozzle 12 in the reverse process.
[0011]
When the upper end of the nozzle 12 and the upper end of the sleeve 13 are in the first position where the upper end of the sleeve 13 is flush with the lower limit position of the sleeve 13, the content adheres only to the nozzle 12, so the height of the top surface of the content is high. There is no change in the position, and the sleeve 13 rises to ensure sealing performance. When the sleeve 13 is in the second position where the upper end of the sleeve 13 is slightly above the upper end of the nozzle 12 at the lower limit position of the sleeve 13, the content is between the upper end surface of the nozzle 12 and the upper end surface of the sleeve 13. Since it adheres to both, as the sleeve 13 rises, the height position of the top surface of the contents also rises, the volume of the whole contents changes, and the contents become negative pressure. Suck back into the container. At the same time, the upper end of the sleeve 13 is closed by the stopper plug 25, and the residual content in the nozzle 12 is sealed to prevent the upper end 14 of the nozzle 12 serving as the spout from being contaminated.
[0012]
【The invention's effect】
The spout antifouling cap according to the present invention can exert a dirt preventing function only with two articles of the drive lever 16 and the sleeve 13 as increasing parts. By adopting the structure, it is possible to make one article, in any case, the number of parts is extremely small, and the dirt prevention is realized by a complete sealing function, and the operation is also simple.
[0013]
From the above description, it is possible to obtain a spout antifouling cap that requires only a small number of parts, has a simple structure, is reliable in operation, and is easy to manufacture.
