Description

[Detailed description of the invention] The present invention relates to a liquid dispensing container that can be freely used for quantitative dispensing and non-quantitative dispensing as needed.

Conventionally, containers capable of dispensing a fixed amount are widely known, but in some cases, it may be desirable to be able to dispense both a fixed amount and a non-metered amount.

The proposed container is intended to enable this kind of use.
Referring to the drawings below, reference numeral 1 denotes a liquid storage container body with a mouth portion 2 protruding upward, and a body portion 3 of the container body is elastically compressible.

The upper member 5 is suspended in the container body by fitting the outer peripheral wall 4 into the mouth and neck.

The upper member has an inward flange 6 protruding from the lower end of the outer circumferential wall 4, and a liquid discharge tube 7 protruding upward from the inner circumferential edge of the inward flange coaxially with the outer circumferential wall 4. A fitting cylinder 9 having a liquid outflow hole 8 in a part of the wall is vertically disposed coaxially with the discharge cylinder 7.

A liquid reservoir chamber 10 is formed between the outer circumferential wall 4 and the liquid discharge cylinder 7 and has an inward flange as a bottom wall and has an open upper end.

It is preferable to attach an engagement flange 11 to the top surface between the container bodies at the upper end of the outer peripheral wall.

A small number of liquid outflow holes 8 are provided in the middle part of the fitting cylinder.

An elastic cylinder member 12 is fitted into the fitting cylinder 9 to airtightly close the liquid outflow hole 8.

The elastic cylindrical member has openings on both upper and lower ends.

At the lower part of the above-mentioned upper member fitting cylinder 9, there is a cylinder part 1 provided at the upper end part.
3 are fitted, and the lower member 14 is suspended within the container body.

In the lower member, a liquid outlet tube 15 is vertically disposed from the lower end of the cylindrical portion 13, and a check valve 16 is provided in the liquid outlet tube.

The cylindrical portion 13 does not block the liquid outflow hole 8, and the lower end of the liquid outlet tube is provided close to the bottom wall of the container body.

The check valve 16 is opened when the container is erected and closed when the container is inverted.

In the illustrated example, an inward flange is provided on the inner surface of the upper end of the liquid outlet cylinder, and the lower surface of the flange is a tapered surface with a smaller diameter at the top, which serves as the valve seat 16a. A ball valve 16b is fitted in the valve chamber so as to be movable up and down.

The large inner diameter portion of the valve chamber can be easily formed by shallowly fitting the small inner diameter cylindrical portion 15b into the large inner diameter cylindrical portion 15a and forcing the liquid outlet tube 15 as shown in the figure.

However, the check valve can be replaced with other conventionally known check valves.

In the above configuration, the liquid 17 is placed in the container body,
When the body 3 is squeezed, the pressure inside the container becomes high, so that the liquid passes through the liquid outlet cylinder, further passes through the elastic cylinder member 12 and the liquid discharge cylinder 7, and flows out from the upper end of the discharge cylinder.

If the body of the container is squeezed appropriately, the liquid flowing out from the upper end of the liquid discharge cylinder will be collected in the liquid reservoir chamber 10. When the chamber is filled, the above-mentioned squeezing is stopped and the liquid in the liquid reservoir is poured into the container body. Pour by tilting.

In this way, a fixed amount can be dispensed, but if a fixed amount is not required, the container body is turned upside down as shown in FIG.

In this state, the check valve 16 is closed and the liquid outflow hole 8 of the upper member is also closed by the elastic cylindrical member, so that no liquid flows out.

When the body 3 is squeezed while the container is in an inverted state, the wall surface of the elastic cylindrical member facing the liquid outflow hole is pushed inward against elasticity due to the high pressure inside the container, so that the inner surface of the fitting cylinder and the elastic cylindrical member The liquid flows out through the outer surface and further through the liquid discharge cylinder 7.

When the body compression is stopped, the elastic cylinder member closes the liquid spouting hole 8 again due to its elasticity.

This proposal has the above configuration, and includes pouring out a fixed amount of liquid,
It is convenient because it can be used freely for dispensing liquid in a non-quantitative manner, and even if the container is turned upside down, both the check valve 16 and the liquid outflow hole are blocked, and dispensing is not possible unless the body is squeezed. This prevents liquid from spilling when pouring it out.
