Description

[Detailed description of the invention] This invention provides a reliable seal when the lid is attached to the cap body, which has a liquid squeezing structure inside the spouting cylinder, while allowing the lid to easily detach when opened. This invention relates to a sealing device for a cap.

Conventionally, the liquid squeezing structure provided on the cap body attached to the bottle spout has four flat plate-shaped squeezing pieces protruding from the periphery of the spout toward the center, as described in Japanese Utility Model Publication No. 53-36277. It is known that the spout is narrowed by setting the spout, but in this case, the spout is
It is shaped like a four-leaf clover, and the center area is narrowed down, but the closer you get to the spout on the periphery, the wider the spout becomes. There was a problem that the content liquid might be discharged, and the squeezing effect could not be expected very much at the beginning of pouring. In addition, as described in Japanese Utility Model Publication No. 51-47561,
It is known that the aperture hole for squeezing the liquid in a V-shape when dispensing the liquid content is formed by a top plate that slopes downward as it reaches the narrowest part of a flat plate. The squeeze piece narrows the spout and squeezes out the liquid, so if the container is tilted during pouring, the content liquid will be blocked by the flat squeeze piece at the bottom of the V-shape, and the liquid will be blocked by the flat squeeze piece at the bottom of the V-shape. This causes a large amount of liquid to flow out from the high position of the V-shape, and especially when the container is tilted and the contents are poured for the first time, a large amount of liquid rushes above the outlet at once and is squeezed out. After passing through the filter, the liquid content falls like a waterfall and is poured, and if the liquid content is not highly viscous such as honey, there may be problems such as the liquid spilling out after pouring out. When pouring, the container is not always tilted according to the V-shaped slope, so when pouring with the V-shaped slope horizontally, a large amount of liquid may be discharged from the spout at once. I had a problem. Furthermore, when the container is returned to its original tilt and the container is stood up, the liquid tends to remain on the top surface due to surface tension because the surface of the aperture piece is flat, even though it is inclined toward the aperture opening. However, there was a problem in that the residual liquid remaining on the squeeze piece was difficult to return smoothly into the container. Furthermore, since the liquid squeezing structure described in any of the above-mentioned publications is provided so as to be exposed at the spout, there is a problem that the liquid content remaining on the squeezing piece dries on the way back into the container.

Therefore, in the device of the present invention, a dispensing cylinder 4 having an opening 5 is provided in a cap main body 1 attached to a bottle mouth, and at least two dispensing cylinders 4 are disposed in the cylinder 4, each having a front and back surface curved upwardly. In the cap having an aperture structure in which a pair of spherical aperture pieces 6 are provided, and aperture edges 6a of the pair of spherical aperture pieces 6 face each other to form an aperture opening 20, The opening 5 having a flap-like elasticity that can be bent in the warping direction is integrally provided at the tip of the protruding cylinder 4, while the elastic opening 5 is provided on the lid 10 that is locked to the cap body 1. The present invention provides a cap sealing device characterized by integrally providing a close contact annular portion 17 having a curved groove portion 16 that curves in the warping direction. The back surface of the pair of convex spherical squeeze pieces has a function that when the container is tilted during pouring, the content liquid that comes into contact with it is guided along the spherical back surface and squeezed by escaping into the container. Therefore, the liquid content passing through the aperture 20 flows out smoothly without being hindered by the squeezed liquid, and the liquid content passing through the aperture 20 flows through a pair of spherical surfaces, for example, if the aperture 20 is a stream. Since the shaped surfaces of the aperture pieces form opposing mountains between streams, the water flows smoothly down the aperture piece surfaces between the spherical surfaces, like a valley flowing down the stream between the mountains. Furthermore, even when the inclination direction of the container is not along the aperture 20, the spherical aperture piece 6 on the back side prevents the content liquid from being discharged, and even after passing through the aperture 20, the spherical surface of the surface prevents the content liquid from being discharged. This allows for smooth guidance and pouring. Next, when the container is stood up after pouring, the liquid content left on the squeeze piece is quickly guided toward the squeeze opening 20 by the spherical squeeze piece and returned into the container. Further, according to the present invention, when the lid body 10 is attached to the spouting cylinder body 4, the elastic opening part 5 in the shape of a flap is brought into close contact with the curved groove part 16 and warped, so that the elastic aperture part 5 is brought into close contact with the curved groove part 16, thereby ensuring a reliable seal. This prevents the content liquid remaining on the aperture piece 6 from drying and volatilizing, and helps the liquid flow down along the spherical surface. Since the elastic opening 5 applies restoring elasticity in the direction of pushing the curved groove 16 apart, the lid can be opened smoothly and easily, and there is no possibility that the liquid inside will be splashed due to excess force when opening the lid. To provide a cap sealing device that prevents this from happening.

The present invention will be explained in detail with reference to the embodiments shown below. Reference numeral 1 denotes a cap body having an internal thread 2 that screws into the bottle mouth, and a spouting cylinder 4 in the center of the top plate 3.
is provided in one piece. The dispensing cylinder 4 is integrally provided with the elastic opening 5 in the shape of a flap whose diameter increases toward the distal end, and at the base of the cylinder there is an opening 5 that adjusts the outflow amount. A pair of individual aperture pieces 6 are provided. The elastic opening 5 in the shape of a flap has elasticity that allows it to be elastically deformed in the warping direction.

Further, as shown in FIG. 3, the aperture piece portion 6 has a spherical shape with the front and back surfaces convex upward.
Aperture edges 6 of the pair of spherical aperture pieces 6
a are arranged to face each other and form an aperture 20. In the case of the embodiment, the diaphragm edges 6a of the diaphragm piece portion 6 are provided so as to be located opposite to each other along a slight step 7 provided at the base of the cylindrical body. In addition, the back side of the squeeze piece 6 has a hollow spherical shape, and when the container is tilted and the contents are poured, the contents that come into contact with this are guided along the spherical surface and returned into the container, thereby performing a squeezing action. It is something. The cylindrical wall surface 8, which the back surface of the throttle piece 6 faces, is vertically arranged to improve liquid drainage. Since at least two of the aperture piece portions 6 having spherical front and back surfaces may be opposed to each other to form the aperture opening 20, three or four or more may be provided, without being limited to the embodiment.

In the case of the embodiment, a locking ring 9 is provided on the outside of the spouting cylinder 4 at a concentric position. Reference numeral 9a denotes a locking protrusion provided on the upper edge of the outer peripheral wall of the locking ring body 9.

Reference numeral 10 denotes a lid which is attached to the cap body 1, and is attached to the cap body 1 by a hinge portion 11 so as to be openable and closable. In the figure, the inner circumferential wall 12 of the opening of the lid body 10 is configured to fit into the locking ring 9 of the cap body 1, and the inner circumferential wall 12 of the opening has three engagement protrusions protruding from the inner circumferential wall 12. The portion 13 is configured to elastically engage with the locking protrusion 9a of the locking ring 9. Reference numeral 14 denotes an opening handle protruding from the opposite side of the hinge portion 11. The top plate part 15 of the lid body 10 is provided with an elastic opening 5 curved in the recurve direction, as shown in FIG. Close contact annular portion 17 having a curved groove portion 16 to be crimped
are integrated. The curved groove portion 16 is curved in a J-shaped cross section from the inside to the outside, and is freely elastically deformed in the warping direction along the curved surfaces of the elastic opening 5 and the curved groove portion 16 to fit tightly together. It is configured to be sealed.

In the above-described embodiment of the present invention, when the cap body 1 is attached to the bottle mouth, the lid body 10 is opened, and a liquid such as soy sauce or sauce is poured from the pouring cylinder body 4,
Since the throttle opening 20 is not flat but surrounded by a pair of spherical squeezing fluid return channels on the back side of the throttle piece 6, the content liquid heading toward the throttle opening 20 is not obstructed by the squeezing fluid. The liquid that flows out smoothly and passes through the aperture 20 is guided to the spherical aperture pieces 6 on both sides, like a mountain stream that flows along mountains rising on both sides with the aperture 20 as a stream. The liquid flows smoothly along the aperture 20 and flows out from the elastic opening 5. On the other hand, when the bottle is opened after pouring, the remaining liquid flows smoothly down along the spherical surface of the aperture piece 6. , and is housed in the bottle mouth through the aperture opening 20.

At this time, if the lid 10 is attached at the same time as pouring is finished, the elastic opening 5 at the tip of the spouting cylinder 4 will curve in the curved direction and fit tightly into the curved groove 16 of the tight annular portion 17 of the lid 10. Therefore, an elastic and surface-contact sealed state is maintained, and even if the content liquid is highly dry or volatile, the liquid remaining on the squeeze piece is prevented from drying out or deteriorating. The bottle is housed in the container along the spherical surface, so there is no risk of the liquid content spilling out even if the bottle opening is tipped over. Furthermore, when the lid body 10 is opened from the cap body 1, the elastic opening 5 uses its warped elasticity to smoothly press back against the curved surface of the curved groove 16 and elastically separate from the opening 5.
Since the lid is not subjected to excessive force when the lid is opened, it is possible to prevent the liquid from splashing up and dripping when the lid is opened.

As described above, according to the cap sealing device having the liquid squeezing structure according to the present invention, the spout cylinder 4 having the opening 5 in the cap body 1 attached to the bottle mouth
In addition, at least two pairs of spherical aperture pieces 6 whose front and back surfaces curve upwardly in a convex manner are provided in the cylindrical body 4, and the aperture edges 6a of the pair of spherical aperture pieces 6 are Since the aperture openings 20 are configured to face each other, first, the spherical openings 20 that are convex upward in the spouting cylinder, which serve as the spout of the cap, are formed.
The back surface of the pair of individual squeezing pieces has the effect of guiding the content liquid that comes into contact with it along the spherical back surface and squeezing it into the container when the container is tilted during pouring. This has the effect of allowing the content liquid to flow out smoothly without being hindered by the squeezed liquid, and after passing through the aperture opening 20, for example, the aperture hole 2 of the present invention
If 0 is a width, a pair of spherical aperture pieces 6
Since the surfaces of the above-mentioned ridges form opposing mountains between the ridges, the liquid content smoothly flows down the surface of the spherical diaphragm piece sandwiching the diaphragm opening 20, as if flowing down the ridge between the ridges, and enters the opening 5. This has the effect of smoothly pouring the liquid to the outside, and even when the inclination direction of the container is not along the throttle opening 20, the spherical rear throttle piece 6 prevents the content liquid from being discharged, and the opening 20 Even after passing through the container, the spherical surface of the container has the effect of smoothly guiding and dispensing the contents. Next, when the container is stood up after pouring, the content liquid remaining on the squeeze piece is quickly guided toward the squeeze opening 20 by the spherical squeeze piece and returned into the container. Further, when the lid 10 is attached to the spouting cylinder 4 according to the present invention, the opening 5 having elasticity in the shape of a flap is brought into close contact with the curved groove 16 and warped, resulting in elastic contact and a reliable seal. Since a sealed state is obtained, it is effective to prevent the content remaining on the aperture piece 6 from drying and volatilizing and to help the liquid flow down along the spherical surface. The curved elastic opening 5 applies restoring elasticity in the direction of pushing away the curved groove 16, so the lid can be opened smoothly and easily, and when the lid is opened, there is excess force and the contents are spilled. This has the effect of preventing the particles from scattering.
