Description

[Detailed Description of the Invention] The present invention relates to a coating tube having a ball for uniformly coating a high viscosity substance.

When applying a liquid medicine or the like, a container with a ball attached to the opening is, for example, a container as shown in FIG. This is because the ball 13 partially protrudes from the mouth 12 of the container body 11, and the ball 13
A part of the container main body 11 inside 3 is supported in a constricted manner. Then, a ring-shaped inner cap 15 provided on the inner surface of the top wall of the cap 14 is used to catch the ball 1.
3 is pressed inward of the container body 11.

This container is used by removing the cap 14 and bringing the ball 13 at the tip of the container body 11 into contact with the object to be coated. However, when the cap 14 is attached when not in use, the inner cap on the inner surface of the cap 14 15 presses the ball 13. At this time, since the ball 13 moves slightly inward to the container body 11, the constriction 1 between the ball 13 and the container body 11
6 can prevent the contents from flowing out, but since the mouth of the container body 11 is not pressed in the radial direction from the constriction 16 to the mouth side, the ball 13
A gap is created between the ball 13 and the mouth of the container body 11, the content remaining between the ball 13 and the container body 11 solidifies, and the ball 13 does not rotate when used next time.
This has the problem that it cannot be coated.

This idea was created in view of the above problems.
It is an object of the present invention to provide a tube for applying a high viscosity substance which is configured to be able to be pressed radially inward at the mouth of a container.

The present invention will be explained based on the embodiments shown in the drawings.
Reference numeral 1 denotes a tube body that can be elastically deformed by pressure, and is made of synthetic resin or a laminate made of a plurality of materials. Reference numeral 2 denotes a dispensing tube that houses a coating ball 3 at the end of the mouth side of the tube body 1, and the ball 3 partially protrudes from the dispensing tube 2 and is attached to the dispensing tube 2. The tube body 1 is rotatably accommodated in a manner that cannot be removed from the ball 3.
On the inner side, a support wall 4 for the ball 3 is provided to protrude from the inner circumferential surface of the spouting cylinder 2, a spout 7 is formed in the center of the support wall 4, and the ball 3 of the support wall 4 is
a protrusion 5 formed intermittently in a ring shape on the opposing surface;
A ring-shaped protrusion 6 provided on the inner peripheral surface of the spouting tube 2
The ball 3 is supported by the spouting tube 2 and the ball 3 is easily rotated by leaving a space between the pouring tube 2 and the ball 3 except for the ball 3 supporting portion.
The high viscosity content inside can be supplied to the circumferential surface of the ball 3. The tube body 1 and the spout tube 2 can be formed separately and then integrated by welding or the like, or
It is optional, such as integrally forming both of them from synthetic resin.

The cap 8 that covers the spouting tube 2 is attached to the spouting tube 2 by screwing screws provided on its inner peripheral surface and the outer circumferential surface of the spouting tube 2. Reference numeral 9 denotes an inner lid that stands upright on the inner surface of the top wall of the cap 8, and its shape is a tapered cylindrical body in which the opening diameter at the tip is larger than the diameter at the base end, and its axis is aligned with the axis of the cap 8. In addition, the diameter of the opening at the tip is set to a size that allows the dispensing tube 2 to be inserted into the opening in a tight state. When the cap 8 is screwed onto the spouting tube 2, the inner peripheral surface of the inner lid 9 is configured to press the outer periphery of the opening of the spouting tube 2 radially inward. In the illustrated embodiment, the outer periphery of the spouting tube 2 is also tapered, and the mouth edge of the spouting tube 2 is formed in an arc shape to facilitate fitting of the inner lid into the spouting tube 2.

This tube is used by injecting a high viscosity drug or other liquid into the tube body 1 and pressurizing the tube body 1 to force the contents from the spout 7 into the spout cylinder 2 and adhere to the surface of the ball 3. , ball 3
by applying it to the skin or other surface and rotating it.
The drug solution on the surface of the ball 3 is applied to the skin and other areas. When used in this manner, the contents remain between the bowl 3 and the dispensing tube 2 and other narrow spaces due to their high viscosity. However, on the inner surface of the top wall of the cap 8, there is a cylindrical inner lid that closely covers the outer periphery of the spouting tube 2, and the inner lid has an opening diameter at its tip that is larger than the diameter at its base. Because of the diameter, when the cap 8 is tightened with the spouting tube 2 inserted into the inner lid 9, the inner lid 9 presses the spouting tube 2 radially inward while descending. Further, since a gap is formed between the inner surface of the tube body 1 of the spouting tube 2 and the ball 3, as described above, when the spouting tube 2 is pressed by the inner lid 9,
The spout side of the pouring tube 2 is easily deformed. Therefore, the spout tube 2, the spout, and the ball 3 are in close contact with each other, and everything from the spout to the inside of the spout tube 2 is sealed.
Therefore, even if there is a large amount of highly viscous content remaining inside the spout of the spout tube 2 during storage, the ball 3 will always rotate smoothly even when reused without drying and hardening. It can be applied while moving, and almost the entire amount of the contents can be used without wasting it. Moreover, since the contact state between the inner lid 9 and the spout barrel 2 is made at least on the inner circumferential surface of the inner lid 9 side,
Even if the cap is screwed in shallowly, the opening of the spout barrel 2 can always be pushed radially inward, and the deeper the cap is tightened, the stronger the force to press it radially inward. Therefore, even if the spout or inner lid becomes deformed or worn during use and the sealing effect deteriorates, the sealing effect can be easily maintained by screwing the cap deeply. It is.

In addition, intermittent ring-shaped protrusions 5 are formed on the support wall 4 provided inside the ball 3 of the pouring tube 2 on the surface facing the ball 3, so that the movement of the contents in the ball 3 is prevented. The highly viscous contained material flows out smoothly to the ball 3 side without any problems, and the intermittent formation allows the ball 3 to rotate smoothly.
