Abstract

PURPOSE:To easily open a cap with a single-hand operation to avoid an increase in a number of parts by coupling a pressing member at a lower part of a side wall of a main cap via a hinge, coupling a sliding member to its free end via a hinge and applying a pressure in a sliding direction to the sliding member with the pressing member pushed. CONSTITUTION:When a pressing part 13 is pushed, a sliding part 15 slides to bring a tapered face 17 of a protruding part 18 into contact with a protrusion 20 on an inner face of a sub-cap 6, so that the sub-cap 6 is pushed up to disengage a lid 5 from an ejection port 4. With the pressing part 13 further pushed, a protruding piece 19 at the freest end of the sliding part 15 pushes an inner face of an inverse hinge 9 to have the sub-cap 6 opened. At a position where the sub-cap 6 is completely opened, the sub-cap 6 remains open. Since a lid can be opened with a single operation, handleability can be improved without increasing the number of parts.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap attached to an opening of a container for seasonings, medicines, cosmetics and the like, and more particularly to a cap that can be opened with one touch.

[0002]

2. Description of the Related Art A synthetic resin cap may be attached to the opening of a container for seasonings, medicines, cosmetics and the like. As such a cap, there is known a cap including a main cap having a spout opening to the top wall and a sub-cap closing the spout.

For example, Japanese Utility Model Publication No. 1-66355 discloses that
The lid (sub-cap) is hinged to the cap base (main cap) via the reversing hinge, and a plate member having a taper portion that pushes up the lid and a protrusion that abuts against the back surface of the reversing hinge is attached to the cap base. It has been proposed that the lid is slidably provided on the upper surface, and a lid is opened with one touch by sliding a plate material.

[0004]

In this type of cap, the sub cap can be easily opened by one-handed operation, but on the other hand, it is necessary to prepare a slidable plate member composed of a separate member. Assembling man-hours increase and parts management becomes complicated.

The present invention has been devised in order to eliminate such disadvantages of the prior art, and its main purpose is to:
It is an object of the present invention to provide a container cap that can be easily opened by one-handed operation and can be configured without increasing the number of parts.

[0006]

According to the present invention, a main cap attached to the opening of a container and a sub-cap hinged to the top wall of the main cap via an inversion hinge are provided. A container cap having a slide member slidably provided on the upper surface of the top wall to push up the sub cap by sliding it to one side and push the inner surface of the reversing hinge to open the sub cap. A pressing member is connected to a lower part of the side wall of the main cap via a hinge portion, the slide member is connected to a free end of the pressing member via a hinge portion, and the pressing member is pushed to the one side. This is achieved by providing a cap for a container, characterized in that a sliding direction pressing force is applied to the slide member.

[0007]

With this structure, the main cap, the sub cap, the pressing member, and the slide member can be integrally formed of synthetic resin material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below with reference to specific embodiments shown in the accompanying drawings.

1 to 3 show a container cap constructed according to the present invention. The cap 1 is injection-molded in a developed state as shown in each figure, and has a substantially bottomed cylindrical main cap 2 fitted in an opening (not shown) of a container body, and a main cap. 2 and a sub cap 6 provided with a plug 5 for closing a spout 4 provided on the top wall 3 of the second wall 3 and integrally molded with a synthetic resin material having high elasticity such as polypropylene resin.

The main cap 2 and the sub cap 6 are connected to each other through a flexible hinge portion 7 and a reversing hinge 9 composed of an L-shaped spring piece 8. As a result, the elastic urging force acting on the sub cap 6 is reversed in the closing direction and the opening direction at a certain opening angle.

The main cap 2 is provided with a push opener 10
Are integrally molded. This push opener 10
The main cap 2 includes a pressing portion 13 connected to a lower portion of the side wall 11 via a hinge portion 12, and a slide portion 15 connected to a free end of the pressing portion 13 via a hinge portion 14. A long hole 16 for inserting the spout 4 is formed in the center of the slide portion 15, and a projection 18 having a tapered surface 17 is provided on both sides of the long hole 16 on the upper surface thereof. A projecting piece 19 is provided on the free end.

On the inner surface of the sub-cap 6, as described above, the plug 5 which can project into the spout 4 of the main cap 2 is projected, and the tapered surface 17 of the projection 18 of the slide portion 15 is provided.
A triangular protrusion 20 is provided so as to be capable of engaging with.

Claws 21 project outward from both sides of the slide portion 15, and slits 23 are provided on both inner side surfaces of a slide portion receiving groove 22 formed in the top wall 3 of the main cap 2. In contrast, the claw 21 can be engaged.

Next, the usage procedure of this embodiment will be described. First, the pressing portion 13 in the unfolded state is bent from the hinge portion 12 and attached to the side wall 11 of the main cap 2. Next, the slide portion 15 is bent from the hinge portion 14 and is attached to the top wall 3 of the main cap 2. By pushing the claw 21 provided on the side surface of the slide portion 15 into the slit 23 provided on the inner surface of the slide portion receiving groove 22 of the top wall 3 of the main cap 2, the slide portion 15 is prevented from rising. (See Figure 4). In this state, the main cap 2 is fitted into the opening of the container body in advance.

The sub cap 6 is rotated around the reversing hinge 9 so that the tip of the plug 5 on the inner surface of the sub cap 6 is inserted into the spout 4 of the main cap 2. A constriction that slightly expands in diameter is formed at the tip of the stopper 5, and the elasticity of the material itself tightly fits the spout 4 to maintain the closed state (FIG. 5). ). At this time, the reversing hinge 9 exerts elastic force in the direction of closing the sub cap 6.

When the pressing portion 13 is pushed, the sliding portion 15 slides so that the tapered surface 17 of the protruding portion 18 of the sliding portion 15 comes into contact with the protrusion 20 on the inner surface of the sub cap 6 and pushes up the sub cap 6. As a result, the spout 4 and the plug 5 are disengaged.
In this state, the reversing hinge 9 still urges the sub cap 6 in the closing direction.

When the pressing portion 13 is further pressed, the sliding portion 15
The projection piece 19 at the most free end pushes the inner surface of the reversing hinge 9 to open the sub cap 6. At the position where the sub cap 6 is completely opened, the reversing hinge 9 exerts an elastic force in the direction for holding the opened state, so that the sub cap 6 remains open (FIG. 6). When the pressing of the pressing portion 13 is stopped, the sliding portion 15 and the pressing portion 13 are automatically returned to their original positions by the restoring force of the hinge portions 12 and 14.

To close the sub cap 6, the sub cap 6
May be pushed with a fingertip and rotated to fit the tip of the plug 5 into the spout 4 of the main cap 2.

[0019]

As described above, according to the present invention, since the synthetic resin material can be integrally formed and the lid opening operation can be performed with one touch, the cap of this kind can be handled without increasing the number of parts. It is possible to exert a great effect in improving the property.
