A capped container is known that includes a lid plate that is rotatably connected to the peripheral edge of the opening of the hole via a hinge portion to open and close the discharge hole, and a cap that is detachably attached to the nozzle.

Japanese Unexamined Patent Publication No. 2005-18709

However, in the conventional container with a cap, when the contents are discharged, the lid plate is rotated around the hinge portion to open the discharge hole with the cap removed from the nozzle, so that the cap is lost during this operation. There was a risk.

The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a container with a cap capable of preventing the cap from being lost when the discharge hole is opened.

In order to solve the above problems and achieve such an object, the capped container of the present invention is attached to the container body in which the contents are housed and the mouth of the container body, and the container body is attached. An inner plug having a communication hole that communicates with the inside, and a nozzle that is rotatably attached to the inner plug and has a discharge hole for the contents, and can be attached to and detached from the inner plug or the mouth. A capped container provided with a cap that is externally fitted and covers the nozzle. The inner plug is provided with a plug portion that closes the discharge hole, and the nozzle has the discharge hole formed by the plug portion. The closed lower end position and the discharge hole are opened at a position above the plug portion and are arranged so as to be vertically movable between the upper end position communicating with the communication hole. The nozzle is provided with a guide mechanism for moving the nozzle up and down with respect to the inner plug as the inner plug and the relative rotational movement of the nozzle are performed, and the nozzle and the cap are provided with the nozzle. , And a regulation unit that regulates the relative rotational movement of the cap is provided.

According to the present invention, since the nozzle and the cap are provided with the regulating portion, the nozzle also rotates when the cap is rotated with respect to the container body. At this time, since the inner plug and the nozzle are provided with a guide mechanism, the nozzle moves upward when it rotates with respect to the inner plug. Then, with the nozzle located at the upper end position, the discharge hole is located above the plug portion and is opened to communicate with the communication hole.
From the above, since the discharge hole is opened by rotating the cap with respect to the container body, it is possible to prevent the cap from being lost when the discharge hole is opened.

Here, even if the nozzle and the cap are provided with a push-up portion that moves the cap upward by engaging with each other when the nozzle moves upward with respect to the inner plug. Good.

In this case, since the nozzle and the cap are provided with a push-up portion, when the nozzle moves upward with respect to the inner plug, the cap moves upward with respect to the inner plug or the mouth portion. It becomes possible to easily remove the cap from the inner plug or the mouth, and it is possible to improve the operability when discharging the contents.
If the cap is put on the nozzle when the cap is refitted to the inner plug or the mouth, the raised part of the cap will hit the raised part of the nozzle located at the upper end position. When pushed downward, the nozzle moves downward while rotating with respect to the inner plug by the guide mechanism, and reaches the lower end position. As a result, the nozzle can be positioned at the lower end position and the discharge hole can be closed by the plug portion only by the operation of fitting the cap to the inner plug or the mouth portion, and the operability can be improved. At the same time, it is possible to prevent the discharge hole from being forgotten to be closed.

Further, a recess is formed in either one of the nozzle and the cap, and a protrusion disposed in the recess is formed in the other, and the restricting portion is formed in the recess. A surface of the inner surface of the portion facing the circumferential direction and a surface of the surface of the protruding portion facing the circumferential direction are provided, and the raised portion is a surface of the inner surface of the recess portion facing the axial direction. And a surface of the surface of the protrusion that faces the axial direction may be provided.

In this case, the regulating portion includes a surface of the inner surface of the recess portion facing the circumferential direction and a surface of the surface of the protrusion portion facing the circumferential direction, and the rising portion is the inner surface of the recess portion. Since it is provided with a surface facing the axial direction and a surface facing the axial direction among the surfaces of the protrusions, both the regulating portion and the raised portion are composed of the inner surface of the recessed portion and the surface of the protruding portion. Therefore, it is possible to prevent the structure from becoming complicated.

According to the present invention, it is possible to prevent the cap from being lost when the discharge hole is opened.

The recessed portion 23 has a rectangular shape that is long in the circumferential direction when viewed from the outside in the radial direction. The size of the recessed portion 23 in the circumferential direction is larger than the size of the recessed portion 23 in the axial direction and the distance between the recessed portions 23 adjacent to each other in the circumferential direction. The recessed portion 23 may be appropriately changed, such as by adopting a vertical groove extending in the axial direction.
A plug cylinder 37, a connecting cylinder 38, and an intermediate cylinder 39 are formed on the top wall portion 35 of the nozzle 16.

The plug cylinder 37 projects downward from the peripheral edge of the opening of the discharge hole 15 on the lower surface of the top wall portion 35 of the nozzle 16, and is detachably and tightly fitted to the upper end portion of the plug portion 18. As a result, the discharge hole 15 is closed by the plug portion 18, and the communication between the discharge hole 15 and the communication hole 13 is cut off.
The connection cylinder 38 is tightly fitted in the inner cylinder 34 of the inner plug 14 so as to be slidable up and down. The connecting cylinder 38 is always tightly fitted in the inner cylinder 34 regardless of the axial position of the nozzle 16 with respect to the inner plug 14.

At this time, the discharge hole 15 is located above the plug portion 18 and is opened to communicate with the communication hole 13.

From the above, the nozzle 16 has a lower end position in which the discharge hole 15 is closed by the plug portion 18 and an upper end position in which the discharge hole 15 is opened above the plug portion 18 and communicates with the communication hole 13. It is arranged so that it can move up and down between them.

The cap 17 is detachably fitted to the inner plug 14 and covers the nozzle 16. The cap 17 is, for example, a measuring cup or the like. The lower end of the peripheral wall portion of the cap 17 is located above the lower end portion of the peripheral wall portion 31 of the inner plug 14. A third locking that protrudes inward in the radial direction on the inner peripheral surface of the cap 17 and is detachably undercut and fitted to the second locking projection 31b formed on the outer peripheral surface of the peripheral wall portion 31 of the inner plug 14. The protrusion 17a is formed. The third locking projection 17a is arranged at the lower end of the cap 17.

On the inner peripheral surface of the cap 17, a protrusion 24 arranged in the recess 23 of the nozzle 16 is formed. A plurality of protrusions 24 are arranged at intervals in the circumferential direction. The protrusion 24 is formed in the shape of a rectangular plate with the front and back surfaces facing in the circumferential direction and long in the axial direction. The lower end edge of the protrusion 24 is in contact with or close to the lower surface of the inner surface of the recess 23, which is located at the lower end and faces upward. As shown in FIG. 3, a plurality of protrusions 24 are arranged in one recess 23.

When the cap 17 is rotated around the central axis O, the surface of the inner surface of the recess 23 facing the circumferential direction and the surface of the surface of the protrusion 24 facing the circumferential direction come into contact with each other, so that the nozzle The relative rotational movement of the 16 and the cap 17 is restricted. That is, the regulation that the surface of the inner surface of the recess 23 facing the circumferential direction and the surface of the surface of the protrusion 24 facing the circumferential direction regulate the relative rotational movement of the nozzle 16 and the cap 17. It constitutes a part.

Since the lower end edge of the protrusion 24 is in contact with or close to the lower surface of the recess 23, when the nozzle 16 moves upward with respect to the inner plug 14, the lower surface of the recess 23 becomes the protrusion 24. The cap 17 moves upward by pushing up the lower end edge of the cap 17. That is, when the lower surface of the recess 23 and the lower end edge of the protrusion 24 move upward with respect to the inner plug 14, they engage with each other to move the cap 17 upward. It constitutes a part.

Next, the operation of the capped container 1 configured as described above will be described.

First, when the cap 17 is rotated to one side in the circumferential direction with respect to the container body 11, the inner surface of the recess 23 facing the circumferential direction and the surface of the protrusion 24 facing the circumferential direction become available. The nozzles 16 also rotate when they come into contact with each other. As a result, the above-mentioned hypotenuse portion of the second guide protrusion 36a of the nozzle 16 causes the above-mentioned hypotenuse portion of the first guide protrusion 33a of the inner plug 14 to be on one side in the circumferential direction. The nozzle 16 slides toward the inner plug 14 and moves upward with respect to the inner plug 14.

As a result, as shown in FIG. 2, the plug cylinder 37 is separated upward from the upper end portion of the plug portion 18, and the discharge hole 15 is opened above the plug portion 18 and communicates with the communication hole 13. .. At this time, the lower surface of the recessed portion 23 of the nozzle 16 pushes up the lower end edge of the protruding portion 24 of the cap 17, so that the cap 17 moves upward and the third locking projection 17a of the cap 17 is moved upward. The second locking projection 31b of the inner plug 14 is overcome upward, and the fitted state of the cap 17 with respect to the inner plug 14 is released.

Then, the engaged protrusion 39a of the nozzle 16 engages with the retaining protrusion 34a of the inner plug 14, thereby restricting further upward movement of the nozzle 16. That is, the nozzle 16 is located at the upper end position. At this time, the fitting state of the connecting cylinder 38 of the nozzle 16 with respect to the inner cylinder 34 of the inner plug 14 is maintained.
Next, after removing the cap 17 and opening the nozzle 16, the contents in the container body 11 are passed through the communication hole 13, the inner cylinder 34, the connection cylinder 38, and the discharge hole 15 in this order to discharge. Discharge from the cylinder 35a toward the inside of the cap 17 that has been turned upside down.

After that, when the cap 17 is put on the nozzle 16, the lower end edge of the protrusion 24 of the cap 17 abuts on the lower surface of the recess 23 of the nozzle 16 located at the upper end position, so that the cap 17 is pushed downward in this state. And the above-mentioned oblique side portions of the first guide protrusion 33a and the second guide protrusion 36a, which are in contact with each other, are in sliding contact with each other, so that the nozzle 16 and the cap 17 are in contact with the inner plug 14. It moves downward while rotating to the other side in the circumferential direction.

As a result, the plug cylinder 37 is fitted onto the upper end of the plug portion 18, the discharge hole 15 is closed, and the communication between the discharge hole 15 and the communication hole 13 is cut off. At this time, the third locking projection 17a of the cap 17 gets over the second locking projection 31b of the inner plug 14 downward, and the cap 17 fits outside the inner plug 14.
Then, the lower end opening edge of the intermediate cylinder 39 comes into contact with the upper surface of the top wall portion 32 of the inner plug 14, so that further downward movement of the nozzle 16 is restricted. That is, the nozzle 16 is located at the lower end position.

As described above, according to the capped container 1 according to the present embodiment, the discharge hole 15 is opened by rotating the cap 17 with respect to the container body 11, so that the cap is opened when the discharge hole 15 is opened. It is possible to prevent the 17 from being lost.

When the cap 17 is rotated toward one side in the circumferential direction and the nozzle 16 moves upward with respect to the inner plug 14, the lower surface of the recess 23 of the nozzle 16 is the lower edge of the protrusion 24 of the cap 17. Is pushed upward and the cap 17 moves upward with respect to the inner plug 14, so that the cap 17 can be easily removed from the inner plug 14 and the operability when discharging the contents is improved. be able to.

After discharging the contents, the cap 17 is put on the nozzle 16 and the cap 17 is pushed downward, so that the nozzle 16 moves downward while rotating to the other side in the circumferential direction with respect to the inner plug 14 together with the cap 17. Since the lower end position is reached, the nozzle 16 can be positioned at the lower end position and the discharge hole 15 can be closed by the plug portion 18 simply by fitting the cap 17 to the inner plug 14 and operability. It is possible to prevent the discharge hole 15 from being forgotten to be closed.

A surface of the inner surface of the recess 23 facing the circumferential direction and a surface of the surface of the protrusion 24 facing the circumferential direction provide a regulating portion that regulates the relative rotational movement of the nozzle 16 and the cap 17. The lower surface of the recess 23 and the lower edge of the protrusion 24 engage with each other when the nozzle 16 moves upward with respect to the inner plug 14, thereby moving the cap 17 upward. Since the raised portion is formed, both the regulating portion and the raised portion are composed of the inner surface of the recessed portion 23 and the surface of the raised portion 24, so that the structure can be prevented from becoming complicated.
