Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a pouring cap that is assembled to the mouth tube of a container, and can be easily opened and closed and can satisfactorily pour out contents. The purpose is to

[Conventional technology]

Some types of containers for storing liquids or powders do not require the cap to be tightly sealed. However, if the opening is always open, dust and the like may enter, and it is unclean. Therefore, it is desirable that the opening can be closed when not in use.

As a conventional example that satisfies this demand, a screw cap that is screwed into and attached to a thread formed in the mouth tube of the container, or a spout formed by the cap body assembled in the mouth tube of the container is formed.
Many caps having a structure in which a lid body hinged to the cap body opens and closes are used.

[Problems to be solved by the invention]

However, in the above-mentioned conventional screw cap, the opening and closing operation is troublesome and time-consuming, and the cap that is detached from the container at the time of opening is troublesome and sometimes the cap is lost. There was an inconvenience.

Also, in the case of a cap having a lid plate that is hinged,
Instead of the inconvenience of losing the cover plate that directly opens and closes the container, the cover plate that remains hinged when the container is opened interferes with the pouring operation of the contents. In addition to having a drawback, when opening and closing the lid plate, the fingertips come into contact with the edge of the lid plate located near the spout, so dirt on the fingertip adheres to the lid plate near the spout. However, on the contrary, there is a drawback that discomfort easily occurs due to the contents sticking to the fingertips.

As a conventional technique for solving these inconveniences and drawbacks, there is one disclosed in Japanese Utility Model Publication No. 62-15150. However, this conventional technique has a structure for opening and closing an opening formed in a portion covering a spout. In addition to being complicated, the structure for opening and closing requires a large installation space in the portion covering the spout, and there is a problem that the whole becomes larger than necessary.

Therefore, the present invention has been devised to solve the above-mentioned problems in the prior art, and achieves opening and closing of an opening formed in a portion covering a spout by a simple lateral swing displacement. This is a technical issue, and the object is to make the overall configuration simple and compact.

[Means for solving problems]

Hereinafter, the present invention will be described with reference to the drawings showing an embodiment of the present invention.

The pouring cap according to the present invention is attached to the mouth tube of a container 19 for containing a liquid or powder, and is composed of a main body tube 1, an intermediate cylinder 7 and an outer cylinder body 15.

The main body cylinder 1 is one in which a pouring cylinder 4 is erected at the center of a top wall 3 of a top cylinder, and is attached to a mouth cylinder of a container 19. Moreover, the exterior is assembled so that it cannot be pulled out.

Further, the outer cylinder body 15 is fixedly assembled to the intermediate cylinder 7, the inner flange 17 is connected to the upper end of the peripheral wall 16, and the opening portion 18 is formed in the portion facing the spout cylinder 4. Is.

Then, an opening is formed on the inner peripheral surface of the upper end of the intermediate cylinder 4 described above.
An opening / closing piece 11 which is located between 18 and the pouring tube 4 and which opens and closes the opening 18 is continuously provided via a hinge 12 so as to be swingable in the lateral direction. On the upper surface of the top wall 3 of the main body cylinder 1, a guide mechanism 14 for swinging the opening / closing piece 11 in accordance with the rotation of the outer cylinder body 15 is provided.

[Action]

Since the pouring cap according to the present invention has the above-described structure, when the outer cylinder body 15 is rotated, the outer cylinder body 15 is rotated.
The intermediate cylinder 7, which is fixedly installed in the main body cylinder 1, rotates together with the outer cylinder body 15 and is thereby rotationally displaced with respect to the main body cylinder 1. By the relative rotation of the intermediate cylinder 7 and the main body cylinder 1, the guide mechanism 14 portion provided on the opening / closing piece 11 side coupled to the intermediate cylinder 7 at the hinge and the guide mechanism 14 provided on the main body cylinder 1 side.
Relative displacement occurs between the opening and closing portion, and therefore the opening / closing piece 11 is horizontally displaced about the hinge 12 by the guide mechanism 14 following the relative rotation of the intermediate cylinder 7 and the main body cylinder 1 to open. Department
It is displaced with respect to 18, and the opening / closing piece 11 is moved by this displacement.
The opening / closing switching of the opening portion 18 is achieved by.

In this way, the opening / closing operation of the opening 18 is achieved by the lateral swinging movement of the opening / closing piece 11 in accordance with the rotating operation of the outer tubular body 15, and the opening / closing piece 11 is housed in the outer tubular body 15. Since it is in the opened state, the opening / closing piece 11 does not interfere with the contents pouring operation.

Further, since opening / closing of the opening 18 is achieved by rotating the outer cylindrical body 15 with respect to the cylindrical wall, it is not necessary to bring a fingertip or the like into contact with the rim of the opening 18.

〔Example〕

In the illustrated embodiment, the main body cylinder 1 has a top wall 3 at the upper end of the cylinder wall 2.
A top end of the top wall 3, a guide groove 5 is engraved as one guide mechanism 14, and a peripheral groove 6 is engraved on the lower outer peripheral surface of the cylinder wall 2. There is.

The guide groove 5 is provided on the upper surface of the circular top wall 3 and
Is engraved along a virtual vortex line centering from the center portion to one peripheral end portion, and is provided at four places in such a form.

Next, the intermediate cylinder 7 is formed by connecting four opening / closing pieces 11 to the upper end of a linear cylinder 8 having an inner diameter substantially equal to the outer diameter of the main body cylinder 1 via the hinge 12 as described above. A projecting strip is provided around the inner peripheral surface of the main cylinder 1 at a position corresponding to the circumferential groove 6 (not shown), and the main cylinder 1 is rotatably mounted so as not to slip out.

The opening / closing piece 11 is a substantially right-angled triangular plate piece, and the sides forming the right-angled side portions of the four opening / closing pieces 11 abut each other, so that the central portion of the upper end opening of the cylinder 8 is One of the acute-angled ends of the right and left triangular shaped opening / closing piece 11 is closed by the hinge 12 extending along the axial direction of the cylinder 8.
A predetermined gap is formed between the other acute-angled end and the inner peripheral surface of the cylinder 8, and a guide pin 13 as a guide mechanism 14 is provided on the lower surface of the other acute-angled end so as to hang down. ing.

Therefore, each of the opening / closing pieces 11 closes the central portion of the upper end opening by swinging in the center direction of the cylinder 8, and swings in the lateral direction that is the inner peripheral surface direction of the cylinder 8 to move the upper end opening. The central portion is opened, and this swing is achieved by the mutual rotation of the main body cylinder 1 and the intermediate cylinder 7 and the action of the guide mechanism 14.

That is, in the guide mechanism 14, the guide pin of each opening / closing piece 11
When the opening / closing pieces 11 are engaged with the corresponding guide grooves 5 and the adjacent opening / closing pieces 11 are in contact with each other, the guide pins 13 are guided by the guide pins 13 in the swing limit posture toward the center of the cylinder 8. It engages with the end of the groove 5 near the center of the top wall 3.

Then, by rotating the intermediate cylinder 7 from this posture, the guide pin 13 is guided by the guide groove 5 and moves in the lateral direction which is the inner peripheral surface direction of the cylinder 8, so that the respective opening / closing pieces 11 also rock. They move away from each other and open the center of the top opening.

Further, in the swinging limit posture in which the adjacent opening / closing pieces 11 are in contact with each other, it is sufficient if the opening 18 of the outer tubular body 15 can be closed. This is rather inconvenient because the opening 18 cannot be sufficiently opened in the opening swing limit posture. The number of the opening / closing pieces 11 may be one or four or more as long as the above-described operation is achieved. However, in view of the fun of the operation, it is preferable that each opening / closing piece 11 is opened so as to be split from the center as in the illustrated embodiment.

The guide groove 5 and the guide pin 13 forming the guide mechanism 14 are
It may be on either side of the upper surface of the top wall 3 of the main body tube 1 and the lower surface of the opening / closing piece 11.

In addition, a plurality of engaging strips 9 are provided on the outer peripheral surface of the intermediate cylinder 4 from the upper end to the lower end, and when the outer cylinder body 15 is fitted, it is arranged in a circumferential direction with the inner peripheral surface of the outer cylinder body 15. Engagement prevents mutual rotation, and an engaging groove 10 is provided around the lower portion of the outer peripheral surface of the intermediate cylinder 4, and when the outer cylinder 15 is fitted, By engaging with the inner peripheral surface, mutual withdrawal can be prevented.

[Effect of device]

As is clear from the above description, the pouring cap of the present invention can be opened and closed by a simple operation, and the opening and closing piece for opening and closing is completely stored and held in the outer cylinder body in the open state. Therefore, when pouring out the contents, there is no inconvenience that the opening / closing piece interferes, and therefore, a good pouring operation of the contents can be obtained, and the opening / closing operation force is the same as that of the outer cylinder body. Since it is applied to the cylinder wall, it is not necessary to directly apply an operating force as an external force for opening and closing to the opening and the opening / closing piece, and therefore the fingertip is soiled with the contents or the opening is dirty. Since there is no inconvenience such as attaching the opening and closing pieces and the opening and closing piece is stored in the outer cylinder body, the overall appearance is simple and good, and the opening and closing mechanism of the opening by the opening and closing piece is composed. Simple and Those having excellent effects and many other can be a whole compact.
