However, the outlet 2a or the outlet 2 from which the toothpaste as a content is extruded.
Toothpaste is likely to adhere to the outer peripheral portion of the plug 7 that fits into a, and if the attached toothpaste is hardened,
There is a problem that the plug 7 cannot be fitted into the outlet 2a again.

Further, since the amount of protrusion from the base portion 2 at the outlet 2a is small, there is also a problem that the pushed-out toothpaste easily falls down at the mouth and is not easily cut (see (b)).

The present invention has been made in view of the above problems, and has as its object the purpose of removing the contents even if the contents adhere to the outlet for taking out the contents from the tubular container and solidified. An object of the present invention is to provide a hinge cap in which a fitting plug to be closed can be securely attached, and the extruded contents are sharply cut without dripping down at the mouth of an outlet.

[0010]

In order to achieve the above object, a hinge cap according to the present invention is mounted on a tubular container and is attached to the tubular container so as to be openable and closable by a hinge. In a hinge cap having a lid formed with a fitting plug for closing an outlet for taking out an object, the outlet is connected to a mouth of a tubular container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the hinge cap according to the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the hinge cap 10 has a cylindrical base 11 and a lid 13 connected to the base 11 via a hinge 12. Attached to.

The tubular container 14 has an opening 14c reduced in diameter at one end of a container body 14a via a shoulder 14b, and is formed of, for example, a laminated tube. The container body 14a is filled with the toothpaste P, and by pressing the container body 14a, the mouth 14
The toothpaste P can be squeezed out from c. A screw portion 14d is formed on the outer peripheral surface of the mouth portion 14c (see FIGS. 3A and 3B).

The base portion 11 has a skirt portion 15 whose upper portion is reduced in diameter, and a throttle port (outlet) 16 projecting upward from the center of the upper surface 15a of the skirt portion 15. Inside, a mounting portion 17 protruding downward on the back surface side of the upper surface 15a is formed (see FIG. 1).

The aperture 16 has an upper opening 16a having an upper surface 15a.
and is formed of a small-diameter cylindrical body with a large amount of protrusion separated by a large distance from a, and communicates with the inside of the skirt portion 15 through a lower opening 16b that opens inside the mounting portion 17, and the diameter decreases as going upward. It has an outer peripheral surface 16c.
At the upper end of the outer peripheral surface 16c, a locking portion 16d slightly protruding outward is formed (see FIG. 2B).

The throttle port 16 has a smaller outer diameter and a higher rise than the conventional outlet 2a, and the rise amount is, for example, about 4 to 5 mm higher.

The mounting portion 17 is formed by a cylindrical body having a screw portion 17a on the inner surface side.
The screw portion 14d can be screwed.

Then, by screwing the screw portion 17a into the screw portion 14d, the skirt portion 15 is integrated with the container body 14a by covering the shoulder portion 14b and the mouth portion 14c, and the squeezing port 16 is connected to the mouth portion 14c. The hinge cap 10 can be attached to the tubular container 14 through the communication (see FIG. 3A).

The method of fitting the hinge cap 10 and the tubular container 14 is not limited to the fitting with the screw portion 17a, but may be the fitting with an undercut (convex portion) formed at the lowermost end of the mounting portion 17. good.

At this time, the lower opening 16b is
The upper inner peripheral surface of the mouth portion 14c that is in contact with the outer peripheral surface of the lower opening 16b forms a tapered inner ring that enhances adhesion (FIG. 3).
(B)).

The lid 13 has a height (depth) corresponding to the amount of projection of the aperture 16 and is formed in a cap shape that covers both the aperture 16 and the upper surface 15a. In the open state (see FIG. 1) or the throttle port 16
Can be freely opened and closed in a closed state (see FIG. 3 (a)) that covers.

The lid 13 has a cylindrical plug (fitting plug) 18 projecting from the inner surface of the ceiling (the bottom in the open state, see FIG. 1) at a position corresponding to the aperture 16. A finger hook 19 is protruded at a position opposite to the connection position of.
When the lid 13 is in the closed state, the upper part of the outer peripheral surface of the skirt portion 15 located below the finger rest 19 is
A concave portion 15b is formed so that a finger can be easily hooked.

The plug 18 has an annular outer wall 18 having a large amount of protrusion.
a and an annular inner wall 18b having a small protrusion amount, and a circular groove 18c is formed between the two walls 18a and 18b. At the upper end of the outer wall 18a, a locking portion 18d slightly protruding inward is formed.

When the lid 13 is closed, the outer wall 18a of the plug 18 slides on the outer peripheral surface 16c of the aperture 16 and fits into the aperture 16 from outside. At this time, the inner wall 1
8b is inscribed in the inner peripheral surface 16e of the throttle opening 16. The throttle opening 16 is fitted into the circular groove 18c and the locking portion 18d is locked by the locking portion 16d, so that the plug 18 Closes the throttle port 16 and maintains this state.

Therefore, when the lid 13 is closed, the plug 1
8 fits inside the throttle opening 16 and is held in the fitted state. In the open state, the plug 18 comes off the throttle opening 16, and the plug 18 functions as a fitting plug for closing the throttle opening 16.

Next, the operation of the hinge cap having the above configuration will be described.

First, as shown in FIG. 3, in order to expose the aperture 16, a finger is put on a finger hook 19 to push the lid 13 upward and open the lid 13 in the closed state (( a)). When the lid 13 is pushed up, the plug 18 fitted with the throttle port 16 moves upward to release the fitting with the throttle port 16.

After releasing the engagement between the plug 18 and the throttle opening 16, the lid 13 is held side by side with the hinge 12 on the side of the skirt 15 (see (c)).

Then, the toothpaste P filled in the container body 14a is squeezed out from the aperture 16 by holding and pressing the container body 14a from both sides. The squeezed toothpaste P is transferred to the brush b of the toothbrush B (see (c)).

At this time, since the aperture 16 is formed to be thin and high in height, the toothpaste P can be cut easily, and the contact point between the brush b and the aperture 16 can be easily seen, and the brush b can be easily brushed. Therefore, the toothpaste P can be reliably transferred to the brush b.

Subsequently, in order to close the aperture 16, the lid 1 is closed.
3 is moved to the base 11 side to close the lid 13 ((a)
reference).

When the lid 13 is brought into contact with the upper portion of the base 11, the upper end of the aperture 16 enters the circular groove 18c, and the plug 18 is fitted into the aperture 16 from outside. Further, by locking the locking portion 18d to the locking portion 16d, the plug 18 is maintained in a state in which the throttle port 16 is closed, and is brought into a state fitted with the throttle port 16.

When the throttle opening 16 enters, the inner surface of the plug 18 slides on the outer peripheral surface of the throttle opening 16.
Even if the toothpaste P remaining on the outer peripheral surface of the throttle opening 16 is dried and solidified, the toothpaste P is shaved off by the inner surface of the plug 18, so that the plug 18 that closes the throttle opening 16 can be securely attached and the hermetic plug can be closed. It becomes possible. Therefore, the resealability is also improved.

[0036]

According to the hinge cap of the present invention, when the lid is opened and the fitting is released, the inside of the cylindrical body is removed.
Part cross-sectional area is smaller than the cross-sectional area of the tubular container, and,
Since the internal volume is set small,
The amount of storage of the contents is reduced, and the cutting of the contents is improved.
A fitting plug fits into the protruding part of the outer periphery of the upper end of the cylindrical body.
So that even if the contents adhere to the outer periphery of the upper end of the cylindrical body,
The contents are cut even further because they are wiped by the stopper.
