Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an opening/closing mechanism for containers such as shampoo and conditioner.

[Prior art and its problems]

Conventionally, the opening and closing of this type of container mouth has been accomplished by attaching and detaching a cap attached to the container mouth. In this case, it is troublesome to attach and detach the cap, and if the cap is very small, there is a risk that it will be lost. Therefore, by rotating the cap,
A device has been proposed in which the cap is moved up and down slightly relative to the container to open and close the content outlet hole provided in the cap, but this method involves fitting the outlet hole in the cap with a protrusion fixedly provided relative to the container. When the container is opened and closed repeatedly, the above-mentioned outflow hole and the protrusion are worn out due to relative rotation, and the sealing performance is impaired. In addition, the vertical displacement of the cap is small,
It is difficult to determine whether the container is open or closed at a glance, and consumers may sometimes mistakenly use the container, such as by turning it upside down with the container open and spilling the contents.

[Means for solving problems]

The opening/closing mechanism of the container according to the present invention has a downward bending feature.

A: a container body 10; B: a substrate 20 attached to the mouth portion 12 of the container body 10; and a guide rod 22 erected in the center of the substrate 20 and having a conical tip 28; C an inner cap 14 having a through hole 24 in the vertical direction; C an inner circumferential surface having a male screw portion 42 on the outer circumferential surface and a conical tip; and an outer circumferential surface of the guide rod 22; There is a gap 46 between the holes and an extraction hole 40 at the top.
A flange portion 3 is provided with a through hole in the lower part.
8, a vertical groove 30 provided on the outer peripheral surface of the guide rod 22, and the sliding lid 1 fitted into the groove 30;
E has a means for preventing relative rotation consisting of a vertical protrusion 44 provided on the inner circumferential surface of the sliding lid 16; and a rotary cap 18 which is held immovably in relation to the opening 12, and by rotating the rotary cap 18, the sliding lid 16 moves up and down. The extraction hole 40 is characterized in that it can be opened and closed by the guide rod 22.

[Effect]

To open the mouth of the present invention, by rotating the rotary cap, the sliding lid screwed onto the rotary cap moves upward while being prevented from rotating by the engagement of the groove and the protrusion. Then, the extraction hole that had been closed by the tip of the guide rod and the through hole that had been covered by the flange portion are opened, and the mouth portion is opened.

To close the opening, the sliding lid is moved downward by rotating the rotary cap in the opposite direction to the top. As a result, the extraction hole is closed by the tip of the guide rod, and the through hole is covered by the flange.
The mouth is closed.

〔Example〕

Next, one embodiment of the present invention will be described based on the drawings.

Reference numeral 10 denotes a container body into which contents such as shampoo and conditioner are filled, and the mouth portion 1 of the container body 10 is
2 has an inner cap 14 attached thereto. The inner cap 14 is composed of a disc-shaped base plate 20 fixed to the mouth part 12, and a guide rod 22 protruding upward from the center of the base plate 20.
The substrate 20 is formed to have the same shape as the outer periphery of the opening 12, and is provided with a substantially fan-shaped through hole 24 that is inserted into the opening 12. A matching annular hanging portion 26 is formed. The guide rod 22 is formed into a cylindrical shape having a substantially conical tip 28, and vertical lead grooves 30, 30 are provided on the circumferential surface of the guide rod 22. The inner cap 14 is attached to the container body 1.
In order to mount the hanging part 26 so that it cannot rotate with respect to the

The sliding lid 16 has a cylindrical portion 36 that is open at the bottom.
and a flange portion 38 protruding outward from the lower end of the cylindrical portion 36. The cylindrical portion 36 has an extraction hole 40 bored in its upper surface and a male screw portion 42 formed on its outer peripheral surface. . The inner periphery of the cylindrical portion 36 is made larger than the diameter of the guide rod 22 so that it can be fitted loosely, and is provided with a protrusion 44 that fits into the lead groove 30 of the guide rod 22. 30 and the protrusion 44, the sliding lid 16
is arranged so as to be non-rotatable but movable up and down with respect to the inner cap 14 (see FIG. 4). Said cylinder part 36
The upper part of the inner periphery has a conical shape corresponding to the shape of the tip 28 of the guide rod 22, and the top of this conical shape serves as the outflow hole 40 and penetrates through it. Reference numeral 46 is a gap between the circumferential surface of the guide rod 22 and the cylindrical portion 3.
6, and the contents flow within the space 46. The flange portion 38 is formed to have the same shape as the mounting portion 20 so as to cover the through hole 24.

The rotary cap 18 is formed into a closed cylindrical shape with an open bottom, and has a through hole 49 having a female threaded portion 48 at the top, and an annular inner wall 50 extending vertically from the periphery of the through hole 49. . The female threaded portion 48 is screwed together with a male threaded portion 42 provided on the outer peripheral surface of the sliding lid 16, and by rotating the rotary cap 18, the sliding lid 16 can be moved in the vertical direction. There is. 52 is an outer wall of the rotary cap 18, and the inner circumference of the outer wall 52 is formed to be the same as the outer diameter of the opening 12 of the container body 10 (also the outer diameter of the base plate 20 and the flange portion 38). An annular groove 56 that fits into an annular projection 54 formed on the outer periphery of the mouth portion 12 is formed below the outer wall 52, so that the rotary cap 18 can be easily removed from the container body 10. is being prevented. The height of the inner wall 50 in the vertical direction is smaller than the height of the cylindrical portion 36 of the sliding lid 16, and this dimensional difference becomes the moving distance of the sliding lid 16 in the vertical direction.

The opening/closing operation of the container will be explained with reference to FIGS. 2 and 3. FIG. 2 shows that the extraction hole 40 is connected to the guide rod 2.
