However, a conventional liquid container is a container that can apply a liquid such as an adhesive using a brush attached to a cap of the liquid container. It often happens that a liquid container without a cap is knocked down by hitting a limb or the like. In this case, a large amount of liquid inside the liquid container leaks from the container opening. The worker needs to interrupt the coating operation once and perform the cleaning process, and there is a problem that extra work occurs and work time is lost on site.
In addition, when the liquid in the container is sucked into the brush attached to the cap, if the amount of liquid in the container is sufficient, there is also a problem that the brush is caused to suck more liquid than necessary. In this case, the excess liquid sucked by the brush is dropped while the brush is squeezed at the edge of the container mouth, but there is an inconvenience that the periphery of the container mouth becomes dirty with the squeezed liquid.

  Therefore, the present invention prevents or reduces the liquid in the liquid container from leaking out of the container mouth even if the liquid container falls, and a new liquid container is installed particularly when the brush is attached to the cap. An object of the present invention is to provide a perforated inner stopper that prevents the liquid from being excessively attached to the brush at the stage of opening and use, and a cap for the container with the inner stopper.

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

  FIG. 1 shows an external configuration of a perforated inner plug according to an embodiment of the present invention. The perforated inner stopper 10 is roughly divided into a mooring part 11, an upper edge part 12, and a guide path 13, and the mooring part 11 and the guide path 13 constitute a trunk part.

  FIG. 2 shows a cross-sectional view through the central axis of the perforated inner plug 10, and FIG. 3 shows a top view of the perforated inner plug 10. The characteristics of the structure will be described later. In particular, FIG. 2 shows that a hollow structure (hollow part 14) extending from the opening of the upper edge part 12 of the inner plug 10 to the opening 13a of the guide path 13 is shown. .

  FIG. 4 shows an external configuration example of a liquid container to which the perforated inner stopper according to one embodiment of the present invention can be applied. The liquid container 20 shown in FIG. 4 has a container opening (not shown), and a cap 22 is attached to the container opening. In one embodiment, a screwing groove is formed on the outer side surface of the container mouth, and a screwing groove is also formed on the inner side surface of the cap.

  FIG. 5 shows an external configuration example of the cap in the case where a brush-like rod-shaped handle member is provided on the cap of the liquid container to which the perforated inner stopper according to the embodiment of the present invention can be applied. A rod-shaped handle member 23 with a brush 24 is attached to the cap 22 shown in FIG.

  FIG. 6A shows a holed stopper 10 according to an embodiment of the present invention, a liquid container 20 to which the holed stopper 10 is attached, and a container opening 21 of the holed stopper 10 or the liquid container 20. It is a schematic diagram which shows the external appearance of the screw 22, and the mode of these mounting | wearing.

  As shown in FIG. 6A, the perforated inner stopper 10 is attached to the inner side (and upper part) of the container port 21 of the liquid container 20, and the cap (screw cap) 22 is screwed to the outer side of the container port 21. It is configured as follows. That is, when the perforated inner stopper 10 is used for the liquid container 20 having the cap 22 for the container mouth 21, the perforated inner stopper 10 is attached to the inner side (and upper part) of the container mouth 21 of the liquid container 10. However, the cap 22 can be screwed onto the container port 21 as usual.

  As shown in FIG. 6A (or as shown in FIGS. 1 to 3), the perforated inner stopper 10 includes a mooring portion 11, an upper edge portion 12, and a guide path 13. The mooring part 11 is a cylindrical member configured to be attachable to the container port 21 of the liquid container 20, and the mooring part 11 and the guide path 13 constitute a trunk part. The upper edge portion 12 is provided on the upper side of the mooring portion 11, and has a diameter slightly larger than the diameter of the container mouth 21, thereby preventing the perforated inner stopper 10 from falling into the container 20 and the cap 22. The thickness (thickness) is such that it can be attached to the container mouth 21 as usual.

  The guide path 13 is provided at a lower portion or a lower side of the trunk portion, and is configured to be inserted from the container mouth 21 into the liquid container 20 when the anchoring portion 11 of the trunk portion is attached to the container mouth 21. It is a cylindrical member. The guide path 13 is formed in a tapered shape (that is, a tapered shape) so as to become narrower toward the lower side (that is, the direction from the mooring portion 11 side toward the opening 13a). By forming the guide path 13 in such a tapered shape, the intrusion of air into the liquid container 20 can be reduced, and even if the liquid container 20 is tilted, the air pressure inside the liquid container 20 is reduced. Easy to keep. As a result, when the liquid container 20 fitted with the perforated inner stopper 10 falls, the air pressure in the liquid container 20 acts to reduce the pressure, so that the liquid filled in the container is difficult to leak out from the liquid container 20. Become. Further, when the guide path 13 is tapered, it becomes easy to accommodate the rod-shaped handle member 23 with the brush 24 of the cap 22.

As shown in FIGS. 2 to 3, the diameter (opening area) of the opening 13 a of the guide path 13 is made smaller than the inner diameter (inner cross-sectional area) of the trunk and the diameter (opening area) of the container port 21. Further, the liquid leakage reducing effect when the liquid container 10 falls can be further improved. In addition, the end surface of the opening 13a of the guide path 13 is formed so as to be parallel to the opening surface on the lower side of the trunk portion (or the opening surface of the container port 21 when mounted on the container port 21). Regardless of how the liquid container 20 falls, the effect of reducing liquid leakage can be made constant.
In addition, although the degree of the effect mentioned above may fall, the guide path 13 can also be formed so that it may become a wide cylinder shape (becomes wide) along a straight cylinder shape or the downward direction.

  Inside the mooring portion 11, the upper edge portion 12, and the guide path 13, a hollow portion 14 (see FIG. 2) that is continuous in the longitudinal direction of the perforated inner plug 10 is formed. That is, the mooring portion 11, the upper edge portion 12, and the inner space of the guide path 13 communicate with each other in the longitudinal direction. The hollow portion 14 has a volume (length and diameter) that can accommodate the rod-shaped handle member 23 with the brush 24 attached to the cap 22. Preferably, when the cap 22 is attached to the container mouth so as to be in contact with the upper edge portion 12, the brush 24 is longer than the opening 13a on the lower side of the guide path 13 (so as to protrude). It is preferable to adjust the length in the longitudinal direction.

  As shown in FIG. 2, in the embodiment of the present invention, the mooring portion 11 of the perforated inner stopper 10 is joined to the concave and convex grooves inside the spiral groove 21 a formed in the container port 21 of the liquid container 20. The bulge part comprised so that it may be formed is formed.

  In the perforated inner stopper 10 according to the embodiment of the present invention, when the mooring portion 11 is attached to the container port 21, the liquid container 20 is inserted from between the mooring portion 11 and the upper edge portion 12 and the container port 21. As long as the liquid 30 does not leak, it is sufficient that the adhesion is maintained. Alternatively, when the cap 22 is mounted so as to be in contact with the upper edge portion 12, it is only necessary to maintain adhesion so that the liquid 30 does not leak from between the cap 22 and the upper edge portion 12.

  Various materials such as synthetic resin, silicon resin, Teflon (registered trademark), glass, or metal can be used as the material for the anchoring portion 11, the upper edge portion 12, and the guide path 13 of the perforated inner stopper 10. In particular, the material of the perforated inner stopper 10 may be selected so as not to react (dissolve) with the liquid contained in the liquid container 20. The mooring portion 11, the upper edge portion 12, and the guide path 13 may be integrally formed continuously by an injection molding method or the like. The mooring portion 11, the upper edge portion 12, and the guide path 13 may be made of different materials. Further, as shown in FIG. 1, the engaging edge portion 11 may be subjected to anti-slip processing such as an uneven groove to make it difficult to slip.

  FIG. 6B is a cross-sectional view illustrating a state in which the perforated inner stopper according to the embodiment of the present invention is attached to the liquid container. The bulging part provided in the anchoring part 11 of the perforated inner stopper 10 is uneven on the inner side of the spiral groove 21a formed in the container port 21 of the liquid container 20 (it looks flat in the figure, but also on the inner side of the spiral groove 21a. It can be seen that the upper edge portion 12 is installed at the upper portion of the container mouth 21 so that the liquid in the container 20 is not spilled.

  7 and 8A, the anchoring portion 11 of the perforated inner stopper 10 is attached to the container mouth (inside) of the liquid container 20, and the screw cap 22 is screwed to the container mouth (outside) of the liquid container 20. It is sectional drawing which shows the state mounted (immediately after). Hereinafter, description will be made with reference to FIG. 7 for convenience of explanation. FIG. 8B shows a state after the liquid in the liquid container has been used for a while from the state of FIGS. 7 to 8A.

  As shown in FIG. 7, the liquid solution 20 is filled with the liquid 30, and the guide path 13 of the perforated plug 10 is immersed in the liquid 30. In the example shown in FIG. 7, the length of the guide path 13 is designed so that only the brush portion or the brush tip of the brush 24 of the rod-shaped handle member 23 attached to the cap 22 protrudes from the opening 13 a of the guide path 13. (That is, in the mounting state of the figure, the length of the guide path 13 is such that when the cap 22 provided with the brushed rod-shaped handle member 23 is mounted on the upper fastening portion, the brush tip of the brush 24 is connected to the guide path 13. It is configured to be longer than the open end).

  The liquid 30 contained in the liquid container 20 is a liquid such as water, alcohol, oil, resin, acid, organic solvent, adhesive, lubricant, or paint. Although not limited, the liquid leakage reducing effect of the perforated inner plug 10 is more effective for the liquid 30 having viscosity than water or oil. For example, although this invention is not limited to these, the viscosity of the liquid 30 in one Embodiment of this invention is 1-10000 mPa * s at room temperature, More preferably, it is 150-2500 mPa * s. Of course, even if the liquid is water or oil, the effects of the present invention can be obtained.

  As another example of adopting the liquid container 20, a nail polish bottle having a cap attached with a rod-shaped handle member having a brush at its tip is also conceivable (in this case, the size and dimensions of the nail polish bottle are variously known in the art). Size and dimensions can be adopted).

  When applying the liquid 30 in the liquid container 20, the worker turns and lifts only the portion of the cap 22, and removes the excess liquid 30 attached to the rod-shaped handle member 23 and the brush 24 from the inside of the guide path of the perforated inner plug 10. Then, the liquid 30 attached to the brush 24 can be applied to the object. When the brush 24 is refilled with liquid, the worker soaks only the portion of the brush 24 in the liquid 30 contained in the hollow portion 14 of the perforated inner plug 10, replenishes the brush 24 with the liquid 30 and continues the coating operation. be able to.

  When the liquid 30 contained in the hollow portion 14 in the perforated inner plug 10 is used while the liquid container 20 is left standing, the liquid 30 in the liquid container 20 is used as shown in FIG. The water level 30b of the liquid 30 in the hollow portion 14 is lower than the water level 30a. This is because the space between the container port 21 of the liquid container 20 and the mooring portion 11 of the perforated inner plug 10 is hermetically sealed (including a completely sealed state and a substantially sealed state). By not going inside (or hard to go). That is, when the water level 30a in the liquid container 20 decreases and the space 40 increases, the pressure of the air in the space 40 of the liquid container 20 tends to be reduced compared to the atmospheric pressure.

  By using the perforated plug 10 according to the embodiment of the present invention, the space in the hollow portion 14 generated by the liquid level 30b in the hollow portion 14 being lowered and the inner wall surface of the guide path 13 are used. A person can drop the excess liquid 30 attached to the rod-shaped handle member 23 and the brush 24. As a result, dripping from the rod-shaped handle member 23 and the brush 24 can be reduced, thereby reducing the contamination at the work site. Further, by forming the guide path 13 in a tapered shape, the space above the hollow portion 14 can be made relatively large, and a space for dropping the liquid 30 attached to the rod-shaped handle member 23 and the brush 24 is secured. Further, an improvement in the effect of reducing liquid leakage due to the diameter of the opening 13a being smaller than the diameter of the container port 21 is also achieved.

  FIG. 9 shows a state in which the liquid 30 is leaking in a state where the liquid container 10 is laid down, and a liquid container (A) having a perforated inner plug according to an embodiment of the present invention and a conventional liquid container (B). FIG. 10 is a diagram schematically showing a cross section of FIG. 9A.

  As shown in FIG. 9B, if a conventional liquid container 20 that is not equipped with the perforated inner stopper 10 is laid down, a large amount of liquid 30d comes out vigorously. However, as shown in FIG. 9A, even if the liquid container 20 fitted with the perforated inner stopper 10 is laid down, the amount of the liquid 30c that comes out is greatly reduced, and the liquid 30c is discharged. Coming momentum is also reduced. This is because, as shown in FIG. 10, since the perforated inner stopper 10 is attached, even if the liquid container 20 falls down sideways, it is difficult for air to enter the liquid container 20 from the outside. This is because when the liquid in the container 20 tries to go outside, the pressure reducing effect of the space (air) 40 inside the liquid container 20 due to the liquid level 30a inside the liquid container 20 lowering suppresses liquid leakage.

  Therefore, even if the worker accidentally lays down the liquid container 10, the liquid 30 c leaks a lot and can be rebuilt based on the liquid container 20 before spreading the contamination at the work site. Even if it leaks outside, the amount is small. Thus, by using the perforated inner plug 10 of the present invention, it is possible to prevent or reduce contamination at the work site and to reduce the spread of contamination.

  In addition, as shown in FIG. 10, since the perforated inner stopper 10 is attached, the area in the liquid container 20 in contact with the outside air with the screw cap opened is reduced. There is also a special effect that the liquid is less likely to volatilize. For example, when the planar diameter of the container 20 is 10 cm and the average planar diameter of the guide path is 1 cm, the area ratio is 100: 1. That is, the area where the liquid in the container 20 in contact with the outside air when the perforated inner stopper 10 is attached can be reduced to 1/100 as compared with the case where the perforated inner stopper 10 is not attached. The liquid is difficult to volatilize.

(Other variations)
FIG. 11 shows a variation of the perforated inner plug according to another embodiment of the present invention. FIG. 11A shows a mooring portion 1111 having a bellows structure of two or more steps (consisting of two or more bulging portions, each bulging portion having a repetitive structure having peaks and valleys). A perforated plug is provided. FIG. 11B shows a perforated inner plug having one or more holes 1121a to 1121c (four or more holes may be provided) on the side surface of the guide path of the above-described holed inner plug. ing. FIG. 11C shows a perforated inner plug provided with an anchoring portion composed of one or more locking projections 1131a to 1131c (sometimes four or more projections may be provided). FIG. 11 (D) shows a perforated inner plug provided with an anchoring portion composed of one or more locking projections 1141a to 1141c (which may be provided with four or more projections) each having a return structure. Yes.

  FIG. 11 (E) shows that the surface is subjected to some anti-slip processing, or the surface processing is performed when the diameter of the section is just an appropriate fit in relation to the container diameter of the liquid container. Shown is a perforated plug with a mooring 1151 that may be absent.

  FIG. 11F shows a further modification. The mooring part 1161 has a substantially cylindrical shape in FIG. Alternatively, the mooring portion 1161 may be subjected to a taper process that is gentler than the taper process applied to the guide path, and may be subjected to a taper process opposite to the taper process applied to the guide path. .

(Cap for container with inner stopper)
Still another embodiment of the present invention relates to a cap for a container with a stopper. The cap for a container with an inner stopper according to another embodiment of the present invention includes a cap for a liquid container and the above-described perforated inner stopper 10 regardless of whether or not the cap is provided with a rod-shaped handle member with a brush. Is configured as a “cap unit”.

The cap unit in that case does not have to be an inseparable (non-separable) unit in which the cap for the liquid container and the holed stopper 10 are completely integrated, and may be of the following form. .
That is, until the cap is mounted on the liquid container (typically screwed), the upper edge 12 of the perforated inner stopper 10 is locked inside the cap by a locking structure (not shown), and the unit is connected to the liquid container. When attached (typically screwed), the perforated inner stopper 10 is inserted into the container opening of the liquid container together with the cap, and the anchoring portion of the inner stopper 10 is anchored inside the container opening.
Next, when the cap is removed from the liquid container, the anchoring (locking) force of the anchoring portion of the perforated inner stopper 10 to the container mouth is higher than the locking force of the inner stopper 10 to the inner side of the cap. In addition, only the cap is removed while the perforated plug 10 is attached to the liquid container.
The present invention also envisages a cap for a container with an inner stopper having such a structure.
