Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a tube with an applicator function that can directly apply medicine such as ointment to an affected area.

BACKGROUND ART Conventionally, when applying a medicine such as an ointment directly to an affected area using a container, the method was to first transfer an appropriate amount of the medicine to the fingertips or palm, and then apply it again to the affected area. According to this method, the fingertips and palms must be clean, and if the fingertips and palms are unclean, there is a problem that the affected area will be contaminated by the application of the drug.
Therefore, it was a hassle to thoroughly wash and disinfect the fingertips and palms before application.

Therefore, in order to save such trouble, we
A tube with a coating function disclosed in No. 3896 was developed. That is, the tube with coating function shown in FIG. 3 is a metal tube 5 made of aluminum or the like.
0, an inner plug body 51 and an outer cap 52. A male screw 54 for fixing the dome-shaped inner stopper 51 to the mouth 53 is screwed onto the outer periphery of the mouth 53 of the metal tube 50 . On the other hand, a cylindrical fitting tube 5 is located at the center of the dome-shaped inner plug body 51.
5 hangs down, and a female screw 56 that is screwed into the male screw 54 is screwed onto the inner circumferential surface of this fitting cylinder 55 .
The male screw 54 of the opening 53 and the female screw 56 of the fitting cylinder 55 are screwed together, so that the dome-shaped inner plug body 51 is firmly fixed to the opening 53 of the metal tube 50. A curved coating surface is formed on the upper surface of the inner plug body 51, and a coating hole 58 communicating with the opening hole 57 of the metal tube 50 is formed in the center of the curved coating surface.
is bored so as to open the upper part of the fitting cylinder 55. Furthermore, an outer cap 52 is attached to the upper part of the inner plug body 51. The outer cap 52 has an inner peripheral surface shaped so as to closely fit into the dome-like shape of the inner plug body 51. And outer cap 5
At the center of the back surface of 2, there is a protrusion 5 that protrudes slightly downward in order to close the application hole 58 of the inner plug body 51.
9 is formed, and by bringing this protrusion 59 into close contact with the upper end surface of the coating hole 58, the coating hole 5
8 are closed.

Problems to be Solved by the Invention However, in this invention, the protrusion 59 formed at the center of the back surface of the outer cap 52
However, the projection 59 only closes the application hole 58 of the inner plug body 51 from above, and closes the opening hole 57 of the metal tube 50.
Since the metal tube 50 is not closed by directly engaging with it, there is a drawback that the sealing performance and gas barrier property above the mouth portion 53 of the metal tube 50 are insufficient.

This invention was made in view of such conventional problems, and aims to provide a tube with a coating function that improves the gas barrier properties near the mouth of the metal tube.

Means for Solving the Problem In order to solve this problem, the first invention has a metal tube 1 consisting of a nozzle-shaped mouth part 13 that becomes narrower toward the tip, a shoulder part 2, and a body part, and on the outer periphery of the shoulder part 2, A skirt portion 5 of an inner plug body 4 having an application surface 3 on the top surface is fitted, and a coating hole 6 is formed in the center of the top surface of the inner plug body 4, the outer diameter being smaller than the outer diameter of the tip of the mouth portion 13 and larger than the inner diameter. At the same time, the tip of the mouth of the metal tube 1 is inserted into the protrusion 7 on the lower side of the coating hole 6, and the protrusion 10 hanging down from the center of the top surface of the outer cap 9 is inserted into the coating hole 6. Moreover, the tip of the projection 10 is brought into direct contact with the mouth end surface 13 of the metal tube 1 located below the application hole 6. Moreover, the second invention is characterized in that the application surface 3 forms an inclined surface 15 in the first invention.

Function The function of this device having the above structure will be explained. The protrusion 10 hanging down from the center of the top surface of the outer cap 9 is attached to the mouth 13 of the metal tube 1.
Since the mouth opening 8 of the metal tube 1 is closed by the protrusion 10 in direct contact with the tip, the gas barrier properties of the mouth 13 of the metal tube 1 are improved.

Example Next, this invention will be explained based on the drawings.

FIG. 1 and FIG. 2 are drawings showing an embodiment of a tube with a coating function according to this invention. FIG. 1 is a drawing showing a tube with a coating function according to the first invention. 1 is a metal tube made of aluminum or the like, and this metal tube 1 has a shoulder portion 2.
is formed in two stages. A recess 11 is formed on the outer periphery of the intermediate portion of the shoulder portion 2 provided with this step, and a convex portion 12 formed on the skirt portion 5 of the inner plug body 4 is fitted into the recess 11. There is. On the other hand, the inner plug body 4 has a curved application surface 3 on the top surface,
A coating hole 6 is bored in the center thereof. A protrusion 7 is formed on the lower side of the coating hole 6, and the mouth 13 of the metal tube 1 is located inside the protrusion 7.
The tips of the two are fitted. In this way, the inner plug body 4
is at two locations: the lower side of the coating hole 6 and the skirt portion 5,
It is firmly fitted into the mouth part 13 of the metal tube 1. Note that the shape of the shoulder portion 2 of the metal tube 1 may be that of a normal tube without a step. Further, a male screw 14 is screwed onto the outer periphery of the skirt portion 5 of the inner plug body 4, and an outer cap 9 is screwed onto the outer periphery of the male screw 14. The feature of this device is that when the outer cap 9 is completely screwed onto the outer periphery of the male screw 14 of the inner plug body 4, the tip of the protrusion 10 hanging down from the center of the top surface of the outer cap 9 is connected to the opening of the metal tube 1. The protruding portion 10 directly closes the mouth portion 13 by contacting the tip of the portion 13 . Conventionally, there has been a tube with a dispensing function in which the opening of the inner stopper, which has a dispensing function, is closed with a protrusion of an outer cap, but the protrusion of the outer cap directly contacts the metal tube to close the mouth. There was nothing left. By using a resin having gas barrier properties, such as polyamide, polyethylene terephthalate, etc., as the material for the protruding portion 10 and the outer cap 9, an even greater gas barrier effect can be expected.

Next, a second idea shown in FIG. 2 will be explained.

The feature of the tube with application function according to the second invention is that the inner plug body 4 has an inclined surface 15 instead of the curved application surface 3 on the top surface of the inner plug body 4 of the first invention. It is in. The inclination angle of this inclined surface 15 is
Can be set arbitrarily to 30°, 45°, etc. depending on the object to be coated. The other configurations are the same as those of the first invention, and their explanation will be omitted.

Effects As explained above, according to this invention, the tip of the protrusion of the outer cap is brought into direct contact with the mouth of the metal tube to close the mouth opening of the metal tube. This has the effect of further improving gas barrier properties.
