Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a liquid dispensing container for dispensing a relatively viscous liquid to a relatively small amount.
[0002]
[Prior art]
For example, a spout with a nozzle disclosed in Japanese Utility Model Laid-Open No. 2-25458 is known. The pouring tap is provided by alternately providing a plurality of elastically deformable inward flanges and a plurality of elastically deformable upright cylinders on the top wall that closes the upper surface of the peripheral wall to be fitted to the outer surface of the container body neck. The upper surface of the uppermost cylinder is closed with a top plate by being raised like a bellows, and the nozzle is protruded from the lowermost cylinder to the outside of the side. When the top plate is pushed in, the top wall descends due to elastic deformation and the liquid in the container is poured out.When the top plate is released, the top wall is restored elastically, and at this time, outside air flows into the container body from the nozzle, This is provided to eliminate the negative pressure.
[0003]
[Problems to be solved by the invention]
When a viscous liquid is to be poured into the container with the above-mentioned discharge stopper, the stored liquid will slowly descend along the container body even if the container is tilted. This is time consuming and tedious, especially when the stored liquid is reduced.
[0004]
In the first aspect of the present invention, a partition plate with a through hole is provided at the upper end of the container body so as to distinguish between two chambers, that is, the inside of the container and the inside of the cap. A nozzle is protruded from the cylinder, and a skirt-like portion is attached to the lower end of the valve stem that is suspended from the top plate that closes the upper surface of the uppermost cylinder. A valve is formed with the hole so that the liquid to be dispensed can be stored in the top wall of the cap close to the nozzle, so that the conventional drawbacks can be eliminated. In the case of Claim 2, while solving the subject of Claim 1, the elastic restoring force of the spout top wall is enhanced.
[0005]
[Means for Solving the Problems]

A through hole 31 is formed in the center portion of the pouring tap 4 and the inner surface of the upper end portion of the peripheral wall of the pouring tap, with the outer periphery of the plate sandwiched between the upper end surface of the neck portion of the container body and the outer peripheral portion of the top wall 5. The spout 4 has a top wall 5 with an inward flange 8 attached to the upper end of the peripheral wall and an elastic with a small upper outer diameter standing from the inner periphery of the inward flange. A protruding cylinder, a small cylinder 11 rising from the inner peripheral edge of the upper end of the cylinder, and a top plate 12 closing the upper surface of the small cylinder, and a small-diameter nozzle 13 projecting forward from the upper portion of the small cylinder, and the top plate 12 The upper surface of the skirt-like portion 16 is formed by loosely inserting the valve stem 15 suspended from the center portion into the through hole 31 of the partition plate 30 and expanding downward from the lower end of the valve stem. By making pressure contact with the lower outer edge of the through-hole 31 by the elastic restoring force of the elastic protruding cylinder, the through-hole 31 was closed in a water-tight manner , and the small-diameter nozzle 13 had an inner diameter that prevented the non-high pressure viscous liquid from flowing out .
[0006]
As a second means, the first means is provided, and the elastic protruding cylinder of the top wall 5 of the spout plug is provided with an elastic cylinder 9 having several different diameters and an inwardly attached elasticity attached to the upper ends of these cylinders.

The spout 4 has a peripheral wall 6 suspended from the outer periphery of the top wall 5 screwed in a watertight manner to the outer surface of the mouth and neck, and a groove 7 for fitting a partition plate is provided around the inner surface of the upper end of the peripheral wall. ing. The top wall 5 has an inward flange 8 attached to the upper end of the peripheral wall 6, an elastic cylinder 9 having different diameters, and an inward flange 10 having elasticity attached to the upper end of each cylinder. ..., each cylinder is erected from the inner periphery of the inward flange located below and raised in a bellows shape, and the small cylinder 11 is erected from the inner periphery of the uppermost inward flange. It is blocked by 12 and formed.
[0009]
A small-diameter nozzle 13 that prevents the non-high-pressure viscous liquid from flowing out is projected upward and forward from the upper part of the small cylinder 11, and a valve rod 15 is suspended from the center of the top plate 12 via a fitting cylinder 14. A skirt-like portion 16 is provided at the lower end of the valve stem so as to expand downward and outward. As shown in the figure, the valve stem 15 is fitted into the fitting cylinder 14 that hangs down from the bottom surface of the top plate so that the upper end of the valve stem 15 is fitted into a closed state. It is good to make it fit in the surrounding recessed groove and make it impossible to extract. Of course, the protrusion and the groove may be provided in reverse. The length of the valve stem will be described later.
[0010]
In the illustrated example, a cap 20 is integrally provided on the liquid spout 4 described above. When the cap is provided, the upper part of the spout peripheral wall 6 is formed as a small outer diameter portion 6a, and a thin hinge 21 is formed on one outer edge of both the left and right sides excluding the front and rear portions of the small outer diameter portion as shown in FIG. The lower end edge of the peripheral wall 22 of the cap 20 that covers the upper part of the spout tap is connected via the. The cap 20 is provided so that the lower portion of the peripheral wall 22 can be fitted to the outer surface of the small outer diameter portion 6a. In order to ensure the fitting, engaging protrusions are provided on the outer surface of the upper end of the small outer diameter portion 6a and the inner surface of the lower portion of the peripheral wall corresponding thereto.
[0011]
When the cap is fitted, the front end opening surface of the nozzle 13 is provided so as to be sealed by the upper inner wall surface of the cap peripheral wall 22. Therefore, the upper portion of the cap peripheral wall is tapered, and the nozzle tip surface is inclined so as to be in close contact with the inner surface of the tapered portion. A finger hook 23 is provided at the lower end of the peripheral wall opposite to the thin hinge, and a finger hook recess 24 is provided in the peripheral part of the spout plug below the finger hook.
[0012]
The outer periphery of the partition plate 30 is fitted into the groove 7 formed in the inner surface of the upper end portion of the peripheral wall of the pouring spout 4 as described above, and is placed horizontally on the inner surface of the peripheral wall. It is held between the outer peripheral portion of the top wall of the outlet, that is, the inward flange 8 at the upper end of the peripheral wall. A through hole 31 is formed in the central portion of the partition plate, and the valve rod 15 is loosely inserted into the through hole, and the through hole is sealed on the upper surface of the skirt-like portion 16. That is, in the sealed state, the top plate 12 of the spout tap is pulled down slightly against the elasticity of the top wall 5 by the valve rod 15, so that the upper surface of the skirt 16 is pressed against the periphery of the through hole to seal the through hole, The periphery of the through hole and the skirt-like portion are provided so as to form the valve 32. A groove as a liquid flow path may be provided vertically in the lower part of the valve stem.
[0013]
All the members described above are formed of synthetic resin.
When using the container, put a slightly viscous liquid in the container body 1 in advance, remove the cap 20, and tilt the container body 1 until the skirt 16 is submerged in the liquid. When the top plate 12 of the tap is pushed in for the first time, the bellows-like raised portions formed by the plurality of cylinders 9 and the inward flanges 10 are pushed down against elasticity, and the valve stem 15 is inserted through the top plate 12. Since the skirt-like portion 16 is separated from the peripheral edge of the through-hole 31, the through-hole is opened, so that the liquid in the container flows into the raised portion, and at the same time, the air in the raised portion flows into the container body. . The liquid that has entered the raised portion reaches the inner surface of the base end of the nozzle hole. However, since the nozzle has a small diameter, it cannot be replaced with outside air, and therefore does not flow out of the nozzle.
[0014]
Thereafter, liquid and outside air are sucked into the raised portion by elastic restoration of the raised portion by releasing the top plate, and air in the raised portion enters the container body by pressurizing the raised portion by pushing the top plate, and the liquid is poured outward. Is issued.
[0015]
When the container is erected after the liquid is dispensed, an appropriate amount of liquid and air are contained in the raised portion at this time, and the valve 32 is closed at this time. At this time, liquid in the raised portion can be immediately poured out.
[0016]
The bellows-like raised portion described in the above-described embodiment is formed of, for example, an upper-diameter elastic protruding cylinder such as a dome, and the elastic protruding cylinder is erected from the inner periphery of the inward flange 8, The small cylinder 11 may be erected from the periphery. The top surface of the small cylinder is closed by the top plate 12. This case also has the same operation as in the above-described embodiment, and can be used in the same manner.
[0017]
【The invention's effect】
Since the first aspect of the present invention is configured as described above, a fixed amount of liquid and air are always stored in the portion of the outlet plug protruding cylinder above the partition plate 30 except during the first liquid discharge. In the next liquid pouring operation, the liquid in the raised tube portion is poured out and the air in the raised tube portion enters the container, and when the raised tube is elastically restored by the end of the pouring operation. Since the liquid in the container and the outside air flow into the raised cylinder, it is possible to quickly dispense the viscous liquid as compared with the conventional case.
[0018]
In the case of the invention of claim 2, in addition to the above-mentioned effect, the elastic protruding cylinder is positioned below by the elastic cylinder 9 having several different diameters and the inward flange 10 having elasticity attached to the upper ends of these cylinders. Since the elastic cylinder 9 is formed upright from the inner periphery of the inward flange, the elastic restoring force can be increased.
