Description

[Detailed description of the invention] The present invention relates to a set of 8 stoppers with caps for dispensing a fixed amount of liquid, etc.

The present invention aims to provide a convenient eight-stopper with a cap that can automatically divide and dispense a certain amount of liquid or other contents in the bottle by simply removing the cap from the bottle.

The illustrated embodiment will be described below.

In the figure, A is a stationary frame according to the present invention, which is connected to a container-shaped stopper main body 1 attached to the neck part 52 of a bottle, a check valve 2 equipped at the bottom of the stopper main body, and a check valve 2. It consists of a suction pipe 3 hanging down from the bottom of the stopper body 1, and a pouring tube 4 projecting upward from the stopper body 1 and made of an elastic material such as rubber.

The stopper main body 1 has an outward flange 12 at the upper end of the peripheral wall 11 that abuts against the top surface of the bottle, and the flange is folded inward from the middle to sandwich the flange described below of the spout cylinder 4. That's what I do.

In addition, the center of the bottom wall 13 is recessed one step downward to form a valve chamber 21 in the center of the bottom wall, and a small cylinder 14 is integrally hung downward from the valve chamber 21, and this is connected to a suction pipe. 3 is fitted and hanging down.

In the valve chamber 21, the check valve 2 has a bottom inner surface connected to a valve seat 22.
In the center of this is a valve hole 23 leading to the suction pipe 3.
A valve body 24 made of rubber or the like is installed inside the valve chamber 21 and is seated on a valve seat 22.

The valve body 24 has a tongue-shaped movable valve portion protruding from an annular fixed base, and the movable valve portion is movably seated on the valve seat 22.

The spouting cylinder 4 has a spouting part 42 having an F-shaped longitudinal section and an upwardly opening spout 43 at the tip thereof, which integrally protrudes upward from the cylindrical base 41. An outward flange 44 is integrally provided on the upper part of the outer periphery.

Thus, the spouting tube 4 has the cylindrical base 41 connected to the peripheral wall 1 of the stopper body 1.
1 in an airtight and watertight manner, and the outward flange 44 is clamped to the outward flange 12 of the stopper body 1.

5 is a synthetic resin bottle in which the suction pipe 3 is inserted into the body 51 and the stopper main body 1 is fitted into the neck part 52;
is screwed to the outside of the mouth and neck part 52 at the peripheral wall 61,
A protrusion 63 is provided at the center of the lower surface of the top wall 62 to fit into and close the spout 43 of the spout tube 4, and the spout tube 4 is pushed into the stopper body 1 by its screw engagement. It is an immersed synthetic resin cap.

Since the structure is as shown above, the cap 6 is attached to the mouth and neck part 5 of the bottle 5.
2, the spout 43 of the spout barrel 4 is closed with the cap and pushed down, and the spout 43 of the spout barrel 4 is closed by the cap and pushed down.
is compressed downward, so that the volumes inside the spout tube 4 and the stopper body 1 are minimized.

Next, when the cap 6 is unscrewed, as the cap 6 rises, the spout tube 4 extends upward by its own elasticity, and the volumes inside the spout tube 4 and the stopper body 1 increase. Since the spout 43 is still closed by the cap 6 until it is fully extended, the inside of the spout cylinder 4 and the stopper body 1 become negative pressure, the check valve 2 opens, and the liquid in the bottle 5 is released from the stopper. It is sucked into the main body 1 via the suction pipe 3.

Therefore, the inhaled liquid is poured into the spout 43 by inverting the bottle 5.
Let it flow out.

The amount of liquid sucked into the stopper body 1 is constant each time the above-mentioned operation is performed, and therefore, the amount of liquid poured out from the spout 43 is a constant amount.

According to the present invention, each time the cap 6 is removed from the bottle, the spout tube 4 extends upward due to its own elasticity, and this creates a negative pressure inside the spout tube, so that the contents such as liquid in the bottle are kept constant. The contents are automatically sucked into the main body 1 and divided, and by subsequently removing the cap 6 from the dispensing tube 4 and tilting the bottle, the contents in the dispensing tube 4 can be poured out. A fixed amount can be dispensed each time by simply removing the device, and the amount can always be kept exactly the same.

The structure is extremely simple, and although it essentially includes a pump, it is easy to manufacture and can be provided at low cost.
