Description

[Detailed Description of the Invention] This invention relates to a spout plug that is fitted onto the mouth of a container such as a can or bottle that mainly stores oily liquids such as edible oil, seasonings, and sweeteners.

This type of spout tap has been provided in various ways, but
In both cases, the elastic force of the elastic means provided on the lid shaft side of the stopper body is weak, and the lid cannot be opened and closed smoothly in the vertical direction, making it difficult to open and close the lid, and the lid is not effective in sealing. However, it has disadvantages such as the possibility of liquid leakage.

This invention was devised to eliminate the above-mentioned drawbacks, and the top plate of the stopper body, which is removably fitted into the mouth of the container, is connected from the vicinity of the peripheral edge of one opposing side to the other side. A recess opened toward the circumference is provided, a spout is provided on the open side of the recess, and an elastic plate having a notch in the upper part on the spout side is erected near the rear wall on the closed side of the upper surface of the recess. A partition plate having an elastic piece at the upper corner of the elastic plate side is provided between the spout and the elastic plate on the upper surface of the recess so that both ends are connected to both side walls of the recess. On both side walls between the partition plate, a lid body having a lid portion for fitting the spout at the distal end and a shaft portion for compressing the elastic piece at the base end; By pivoting the elastic plate so that it can be opened and closed in pressure contact with the notch of the elastic plate, the lid can be opened and closed very easily with a single touch, and the pourer can reliably prevent leakage of liquid. It provides a stopper.

An embodiment of this invention will be described below with reference to the drawings.

In the figure, A is a plastic stopper body with a vertical U-shaped vertical section that is removably fitted into the mouth T of a container S, and this stopper body A is opposite to the top plate 1. A recess 2 is provided that is open from the vicinity of one peripheral edge toward the other peripheral edge,
On the open side of the four parts 2, a spout 3 penetrating in the vertical direction is erected so that the height is slightly lower than the top surface of the top plate 1, and near the closed side rear wall 4 on the top surface of the recess 2. An elastic plate 7 having a notch 5 in the upper part on the spout 3 side and several reinforcing support pieces 6 in triangular or square shapes in the lower part on the rear wall 4 side is attached to the ceiling. It is erected at approximately the same height as the top surface of the board 1.

In addition, between the spout 3 on the upper surface of the recess 2 and the elastic plate 7, a partition plate 9 having a downward U-shaped cross section and having an elastic piece 8 at the upper corner on the elastic plate 7 side is installed. A pair of shaft holes 11 are provided in the side walls 10 between the elastic plate 7 and the partition plate 9 of the recess 2 .

Furthermore, around the spout 3 of the recess 2, a closing protrusion 1 is provided on the upper periphery.
2 is formed to stand up a liquid leakage cylinder 13 slightly protruding outward.

On the other hand, B is a plastic lid that seals the spout 3 of the stopper body A, and the lid B has a main plate 14 whose planar shape corresponds to the planar shape of the recess 2. A cylindrical lid part 15 that fits inside the spout 3 is provided on the lower surface of the tip of the main plate 14, and a cylindrical lid part 15 that fits inside the spout 3 is provided around the lid part 15 at a suitable position on the inner circumferential surface to engage the closing protrusion 12. Closing piece 1
A cylindrical liquid leakage lid 17 for fitting outside the liquid leakage cylinder 13 with a protruding numeral 6 is provided.

Further, a shaft portion 18 having a substantially semicircular cross section for compressing the elastic piece 8 is provided on the lower surface of the base end of the main plate 14, and shaft pins 19 are provided protruding from both end surfaces of the shaft portion 18, respectively. In the vicinity of both ends of the shaft portion 18, a guide 20 for fitting each shaft pin 19 into the shaft hole 11 is provided.

Then, each shaft pin 19 of the shaft portion 18 of the lid body B is inserted into each shaft hole 11 of the concave portion 2 of the stopper body A, and the base end is inserted into the notch portion 5 of the elastic plate 7.
It is supported so that it can be opened and closed so that it is pressed into contact with the

In addition, 21 is a groove provided at the lower part of the peripheral wall of the stopper main body A for fitting the peripheral edge of the container S mouth part T, 22 is a reinforcing piece continuous between the liquid leakage tube 13 and both side walls 10 of the recess 2, Reference numeral 23 designates a reinforcing piece provided continuously between the liquid leakage lid 17 and the shaft portion 18, and 24 represents a relief portion provided in the longitudinal center of the shaft portion 18 to prevent the reinforcing piece 23 from coming into contact with it.

Since this device is configured as described above, when in use, the groove 21 of the stopper body 1 is removably fitted to the periphery of the mouth T of the container S, as shown in FIGS. 3 and 4. When opening the lid, the tip of the lid B is pushed up slightly, and as the lid B is swung upwards around the shaft pin 21, the base end of the lid B first touches the stopper body A. The action of compressing the elastic plate 7 backward while sliding the notch 5 of the elastic plate 7 downward, and the circumferential surface of the shaft part 18 of the lid body B pushing the rear surface of the elastic piece 8 of the partition plate 9 of the stopper body A upward. The action of slightly compressing the elastic piece 8 forward while sliding is performed substantially simultaneously (see the dashed line in FIG. 3).

The base end of the lid body B is connected to the notch 5 of the elastic plate 7 of the stopper body A.
The lid body B is swung upward by the strong forward elastic force of the elastic plate 7 that acts when the partition plate 9 comes off, and the lid body B is swung upward by the slight elastic force backward of the elastic piece 8 of the partition plate 9. B is held in a vertical position (see Figure 4).

In addition, when closing the lid, the tip of the lid B is pushed slightly forward to perform the same action as when opening the lid, and then the strong forward elastic force of the elastic plate 7 causes the lid to When the body B is swung downward, the lid body B is brought into a horizontal state due to the slight backward force of the elastic piece 8 of the partition plate 9 and the slight force of forward force of the elastic plate 7. Retained.

Therefore, when opening and closing the lid B, the tip of the lid B can be pushed up or down slightly upward or forward, and the forward elastic force of the elastic plate 7 will cause the lid B to swing smoothly in the vertical direction. Therefore, the lid B can be opened and closed very easily.

Moreover, when the lid is closed, the base end of the lid B comes into pressure contact with the notch 5 of the elastic plate 7 of the stopper body A, and the slight forward elastic force of the elastic plate 7 holds the lid B in a horizontal state. Since it can be held, the lid body B has a good sealing effect and can reliably prevent leakage of liquid.

In addition, when the lid is opened, the lid body B can be reliably held in a vertical position by the slight backward elastic force of the elastic piece 8 of the partition plate 9, so that when pouring out liquid, the stopper body A is moved toward the spout 3 side. The lid body B does not swing toward the spout 3 even when tilted to the side, and the liquid pouring operation is extremely simple.

In addition, by providing the notch 5 in the upper part of the elastic plate 7 on the spout 3 side, the compression and elastic action of the elastic plate 7 in the front-rear direction by the base end of the cover B when the cover B is opened and closed is further enhanced. Not only can this be done smoothly, but by providing several support pieces 6 at the lower part of the rear wall 4 side of the concave portion 2 of the elastic plate 7, the lower part of the elastic plate 7, where the most force is applied when opening and closing the lid body B, is extremely strong. Therefore, it can sufficiently withstand the compression action by the base end of the lid body B.

Such support pieces 6 exhibit particularly excellent effects when the stopper body A is molded from soft plastic.

Further, between the spout 3 on the upper surface of the recess 2 of the stopper body A and the elastic plate 7, there is provided a partition plate 9 whose both ends are connected to both side walls 10 of the recess 2.
By providing this, even if a small amount of liquid leaks from the spout 3, it is not only possible to reliably prevent the liquid from entering the shaft portion 18 side of the lid B, but also to ensure that the liquid does not leak into the recess 2 when opening and closing the lid B. The distance between the side walls 10 is widened, and the shaft pin 19 of the lid body B is connected to the stopper body A.
It is possible to reliably prevent the shaft from being pulled out of the shaft hole 11.

In addition, since the lid B is fitted into the recess 2 of the top plate 1 of the plug body A, the lid B does not protrude from the top surface or the circumferential surface of the top plate 1 of the plug body A. The appearance is also very good.

As explained above, according to this invention, the lid can be opened and closed extremely easily with a single touch, and leakage of liquid can be reliably prevented, and the liquid pouring operation is also simple.
In addition, various effects such as an extremely good appearance can be obtained.
