Description

[Detailed Description of the Invention] The present invention relates to a container cap that is attached to the mouth of a container containing liquid or powder.

Conventional container caps have a dispensing tube for dispensing liquids or powders, but since the dispensing tube is always exposed to the outside, it is unhygienic as it collects dust. .

It is also possible to use a separate detachable cap to cover the dispensing tube, but this is cumbersome as the cap must be removed every time the contents are dispensed.

This invention was made to solve the above-mentioned deficiency.The entire dispensing tube is covered except when dispensing, and when dispensing the contents, the dispensing tube can be exposed with a simple operation. The object is to provide a convenient and hygienic container cap that can be removed.

Embodiments of the present invention will be described in detail with reference to the drawings.

As shown in the figure, the container cap of the present invention includes a cap body 10 attached to the mouth of the container, an outer cap 20 fitted to the outer periphery of the cap body 10 so as to be able to slide vertically.
A link mechanism composed of a lid member 30 and a link member 34 is formed between the cap body 10 and the outer cap 20, and moves up and down in conjunction with the up and down movement of the outer cap 20,
In addition, the through hole formed at the top of the outer cap 20 is connected to the lid member 3.

The cap body 10 has a fitting cylindrical part 11 at its lower part, and the inner peripheral wall of this fitting cylindrical part 11 has a threaded groove 12 that can be threadedly engaged with a thread 2 formed on the outer periphery of the container mouth part 1. is engraved.

An annular flange 13 is provided to protrude radially inward from the upper edge of the fitting cylinder part 11, and a spout pipe 14 is provided to protrude further upward from the opening periphery of the central part of the flange 13. An annular wall 15 formed to have the same diameter as the fitting cylinder portion 11 extends upward from the periphery of the fitting tube 13 .

A plurality of uneven stripes 16 are formed on the outer circumferential surface of the annular wall 15 and the fitting cylinder part 11, extending from the upper end to the lower end, and the uneven strips 16 are formed on the lower inner circumferential surface of the outer cap 20, which will be described later. 21.

The outer cap 20 includes a cylindrical circumferential side portion 22 and a circumferential side portion 22.
It has a top part 23 formed to curve radially inward in an arc shape from the upper edge and close the upper part, and a diameter slightly larger than the outside diameter of the spouting cylinder 14 is formed in the center of the top part 23. A through hole 24 is bored.

The lower part of the outer cap 20 is open, and a plurality of uneven lines 21 are formed in the vertical direction on the inner peripheral surface of the lower part as described above, and these uneven lines 21 and the uneven lines 1 of the cap body 10 are formed.
6 are fitted together, and the outer cap 20 is fitted onto the cap body 10 so as to be slidable in the vertical direction.

Then, when the outer cap 20 is lowered to the lower end, the cap main body 10 and the outer cap 20
The dispensing tube 14 is dimensioned so that the distal end of the dispensing tube 14 protrudes outward beyond the through hole 24 at the top of the outer cap 20.

A pair of lid members 30, 30 and link members 34, 34 are arranged in the space between the cap body 10 and the outer cap 20,
A link mechanism is configured that moves up and down in conjunction with the up and down movement of the outer cap 20 and allows the lid member 30 to open and close the through hole 24 at the top of the outer cap 20.

Each lid member 20 includes a covering portion 31 that covers the through hole 24 of the top portion 23 of the outer cap 20 and slides on the inner circumferential surface of the top portion 23, and a covering portion 31 that extends diagonally downward and parallel to each other from the side of the outer end surface of the covering portion 31. It has a pair of legs 32.32.

As described above, the surface of the covering part 31 is formed into a spherical shape so that it can slide in contact with the inner circumferential surface of the top of the outer cap 20, and the end thereof is formed in a straight line, and the end part is formed in a straight line. 31,
31 cover the through hole 24, they can abut against each other at their ends.

Inside the outer cap 20, a lid member 30. of the same shape.
A pair of parallel leg portions 32, 32 of each lid member 30 are disposed so as to straddle the pouring tube 14, with the lid members 30 facing each other.

The legs 32, 32 of one lid member 30 and the legs 32, 32 of the other lid member 30 intersect with each other near the center, and at this intersection the pins 33° 33
It is pivoted by.

The tips of the pins 33, 33 are connected to the tips of a pair of convex projections 25, 25 that protrude radially inward from opposing positions on the inner upper edge of the circumferential side portion 22 of the outer cap 20. It is fixed.

The tip of each link member 34 is pivotally attached to the end of each leg 32 by a pin 35, and a pair of link members 34 and 34 located on the same side of the spouting tube 14 are also connected to each other. Both ends are pivotally connected by pins 36,36.

The tips of these pins 36 and 36 are connected to the cap body 1.
They are fixed to opposing positions on the inner surface of the annular wall 15 of No. 0.

Therefore, the link mechanism moves up and down in conjunction with the up and down movement of the outer cap 20, and the leg portions 32 are pivotally attached to the inner side of the outer cap at the required positions, so the lid member 30 is moved up and down at this pivot point. The through hole 24 is opened and closed by supporting it.

Although not shown, in addition to directly pivoting the ends of the legs 32, 32 of the lid member 30 and the tips of the link members 34, 34 as described above, there is also a pair of legs pivotally coupled at the center between both ends. A link mechanism may be constructed by interposing a link member.

The container cap having the above structure is used by fitting the fitting cylinder part 11 of the cap body 10 into the container mouth part 1.
As shown in FIGS. 2 and 3, except when dispensing the contents, the pouring tube 14 is housed inside the outer cap 20, and the through hole 24 at the top of the outer cap 20 is also inserted into the cover 31 of the lid member 30. is held closed by.

Then, to pour out the contents, the outer cap 20 can be pulled down.

In this way, when the outer cap 20 is lowered, the pivot pin 33 at the center of the leg 32 of the lid member 30 is fixed to the protrusion 25 formed on the outer cap 20, so the outer cap 20 is lowered.
It descends with 0.

On the other hand, since the pivot pin 36 at the lower end of the link member 34 is fixed to the cap body 10, it does not move, and as a result, both the pivot pins 33 and 36 come closer together.

Therefore, the legs 32 and 32 of the lid member 30 rotate in a direction in which their tips move away from each other using the pivot pin 33 at a predetermined position of the leg 32 as a fulcrum, and the surfaces of the covers 31 and 31 of the lid member 30 are While in contact with the inner circumferential surface of the top of the outer cap 20, they slide in directions away from each other to open the through hole 24 at the top of the outer cap 20.

After that, by further pulling down the outer cap 20,
As shown in FIGS. 4 and 5, the distal end of the spout tube 14 passes through the through hole 24 and projects upward.

In this state, the contents are poured out. After pouring out, the outer cap 20 is pulled up and the pouring cylinder 14 is stored in the outer cap 20.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified in various ways.

For example, instead of using the pair of lid members 30 and 30 as described above, it is also possible to use a double lid member 30 in which the covering portion 31 is formed wide.

In addition, the pin 33 that pivotally attaches the leg portion 32 of the lid member 30 not only fixes the protrusion 25 provided inside the outer cap 20 as described above, but also has a long pin 33 and is directly attached to the inner circumferential wall of the outer cap 20. It may be fixed.

Further, the pin 36 that pivotally connects the lower end of the link member 34 can be fixed to the peripheral wall of the pouring tube 14.

The container cap of the present invention is constructed as described above, and the entire dispensing tube 14 is covered by the outer cap 20 and the lid member 30 except when dispensing the contents. When dispensing, the dispensing tube 14 can be exposed by simply pulling down the outer cap 20, which is extremely convenient and sanitary.
