[0001]

BACKGROUND OF THE INVENTION The present invention relates to a hinged cap. In particular, the present invention relates to means for opening the lid.

[0002]

2. Description of the Related Art A hinged cap is urged in a closing direction by an urging force of a spring of the hinge when the opening angle of the lid with respect to the cap base is smaller than a certain value, and when the angle exceeds the angle. Is biased in the opening direction. by the way,
If the urging force of the spring of the hinge is excessively increased so that the lid is not opened carelessly in the closed state, there is a problem that the usability is lacking because the lid must be pulled up strongly. ing.

Therefore, a device has been proposed in which a plate is provided on the upper surface of the cap base and the cover is opened by pressing the plate (for example, Japanese Utility Model Laid-Open No. 1-66355). This invention will be described with reference to FIG. A lid 22 is hinged to the cap base 21 so as to be openable and closable by a reversing hinge 23.
4 is provided slidably. On the front edge of the plate material 24,
A tapered portion 25 is formed so as to be brought into contact with the front edge of the closed lid 22 and pushed up. The front edge of the plate 24 protrudes from the opening-side edge of the cap base 21, while the rear edge of the plate 24 is formed with a projection 26 that can contact the back surface of the reversing hinge 23. When the front edge of the plate member 24 is pressed to retract the plate member 24, the tapered portion 25
Then, the lid 26 is pushed up, and the projection 26 presses the back surface of the reversing hinge 23 to open the lid 22.

[0004]

In the prior art, since the elongated hole of the slider is exposed to the outside when the lid is opened, foreign matter enters between the slider and the cap base through the elongated hole. Then, the operability of the slider deteriorates, and a problem arises in that the lid cannot be reliably opened.

Further, there is another problem that the appearance of the lid when the lid is opened is impaired because the elongated holes of the slider are conspicuous.
The present invention has been made in view of the above-described problems of the conventional example, and allows the lid to be reliably opened. When the cap is opened, the long hole of the slider is not conspicuous and the appearance is excellent. It is an object to provide a hinged cap.

[0006]

The present invention employs the following technical means in order to solve the above technical problems.

That is, the cap base 1 is attached to the mouth of the container and has a pouring hole on the upper surface for discharging the contents. The outer shape of the cap base 1 can be an appropriate outer shape such as a rectangular parallelepiped type, a cylindrical type or a columnar type.

A lid 2 is formed on the cap base 1 so as to be opened and closed by a reversing hinge 3 so as to open and close a pouring hole of the cap base 1. On the upper surface of the cap base 1, a slider 4 slidably provided is arranged.

On top of the slider 4, a top plate 8 that fits into the spout cylinder of the cap base 1 and is further locked by the cap base 1 so as to cover the top of the slider 4 is arranged.
Here, when the inverted hinge side is the rear side and the opposite side is the front side, the pressing portion 5 is formed on the front edge of the slider 4.

[0010] A tapered portion 6 is formed above the front edge of the slider 4 so that the tapered portion 6 can come into contact with the back surface of the lid 2 or the reverse hinge 3 when the lid 2 is closed. Further, the slider 4 can be formed of a flexible material.

In this case, an inclined surface 7 that rises upward is formed on the inverted hinge side of the cap base 1. The flexibility required for the material of the slider 4 may be such that the trailing edge of the slider 4 is guided by the inclined surface 7 of the cap base 1 so as to be slidable. As the material, for example, the flexible polyethylene can be used.

[0012]

[0013]

When the pressing portion 5 is pressed, the slider 4 retreats and the lid 2 is pushed up by the tapered portion 6 to open the lid 2.

The lid 2 can be opened by guiding the trailing edge of the slider 4 to the inclined surface 7 of the cap base 1 and abutting the rear surface of the lid 2 or the reverse hinge 3. Further, the top plate 8 prevents foreign matter from entering between the slider 4 and the cap base 1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view of the hinged cap of the present invention.

In FIG. 1, the cap base 1 is formed in a rectangular parallelepiped shape. The cap base 1 is attached to the container mouth, and a tubular body 9 is vertically provided inside. A screw 9a is formed inside the cylindrical body 9,
It is adapted to be screwed into the mouthpiece of the container body.

A recess 1b is formed on the upper surface of the cap base 1.
Is formed, and a pouring hole 1d is formed substantially at the center of the concave portion 1b. A pouring cylinder 1a stands upright around the pouring hole 1d. Engagement holes 1c are provided at four corners of the upper surface of the cap base 1, respectively.

A lid 2 is connected to the rear edge of the upper surface of the cap base 1 via a reversing hinge 3 so as to be openable and closable. On the back surface of the lid 2, a plug projection 2a that fits into the pouring cylinder 1a is provided so as to project therefrom.

The reversing hinge 3 has two hinge portions 3a and 3b.
And a reversing spring portion formed between the hinge portions, and these are integrally molded. In addition, the injection cylinder
The fitting strength of the plug 1a and the plug projection 2a is set to such an extent that the lid is not opened carelessly. By this fitting, the closed state of the lid 2 is maintained.

In the recess 1b on the upper surface of the cap base 1, there is provided a slider 4 formed of a flexible material and slidable in the recess 1b in the horizontal direction. When the reversing hinge 3 side is the rear side and the opposite side is the front side, the slider 4 is slidable in the front-rear direction, and a pressing portion 5 is vertically provided at the front edge of the slider 4. .

Further, a tapered portion 6 is formed in the upper portion of the front edge of the slider 4 so as to become lower toward the rear edge. In addition, when the slider 4 slides,
A long hole 4a is formed so that 1a does not hinder sliding.

Further, in the concave portion 1b of the cap base 1 which slidably accommodates the slider 4, an inclined surface 7 which rises upward is provided at the rear edge on the side of the reversing hinge 3.

The inclined surface 7 abuts on the trailing edge of the slider 4 to deflect the slider 4 and guide it upward. Trailing edge of the slider 4 is guided by the inclined surface 7 may be in contact with the back surface of the lid 2, or, but it may also be into contact with the rear surface of the reversing hinge 3.

Further, on the front surface of the cap base 1, there is formed a recess 10 having a width such that the pressing portion 5 of the slider 1 can move in the sliding direction. The lower edge 5a of the pressing portion 5 of the slider 4 the inner bottom surface 10a of the recess 10
The flexible slider 4
To prevent it from sagging downward.

When the lid 2 is closed, the front surface of the pressing portion 5, the front surface 1d of the cap base 1, and the front surface of the lid 2 are flush with each other. Further, the slider 4
A top plate 8 that covers the slider 4 is provided on the upper part of the slider. The top plate 8 has a fitting hole 8a that fits into the pouring cylinder 1a and four engagement protrusions 8b that couple with the engagement hole 1c of the cap base 1. The top plate 8 prevents foreign matter from entering between the slider 4 and the cap base 1.

Next, the operation of this embodiment will be described. When the pressing portion 5 is pressed in the closed state, the pressing portion 5 slides from the front to the rear. Due to this sliding, the tapered portion 6 raises the front edge of the lid 2. At the same time, the trailing edge of the slider 4 is guided upward while bending by the inclined surface 7, and abuts on the back surface of the lid 2 or the reverse hinge 3. The lid 2 is lifted and opened by the action of the tapered portion 6 and the trailing edge of the slider 4. At the same time, the fitting of the plug projection 2a of the lid 2 that has been fitted to the pouring cylinder 1a is released. In this state, when the lid 2 is lifted and opened above the fulcrum of the inverted hinge 3, the inverted hinge 3 opens the lid 2.

[0027]

According to the present invention, since the upper portion of the slider is covered with the top plate as described above, the long hole of the slider is not exposed to the outside. Further, since there is no protrusion on the slider as in the conventional example, the top plate does not have a fitting hole for fitting to the protrusion of the slider.
Therefore, foreign matter does not enter between the slider and the cap base through the elongated hole of the slider or the fitting hole of the top plate, the operability of the slider is maintained well, and the lid can be reliably opened. In addition, the long holes of the slider are not conspicuous and the appearance is excellent.

In the present invention, when the lid is in the closed state,
When the pressure part 5 is pressed, the pressure part 5 slides rearward.
The sliding causes the tapered portion 6 to lift the front edge of the lid 2,
