[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, a plug body 4 is fitted to a mouth 5 of a tubular container 1 according to an embodiment of the present invention, and a cap 2 is fitted to the plug body 4. The inserted state is shown in cross section. The tube-shaped container 1 has a gel-shaped antiperspirant, a deodorant, and the like enclosed therein as a content, and includes a container body 3 and a cylindrical plug body 4 fitted to a mouth portion 5 thereof. It is composed of Note that the cap 2, the container body 3, and the plug body 4 are all elastically deformable synthetic resin molded products.

The mouth portion 5 of the container body 3 projects cylindrically, and its outer peripheral surface has an annular projection 6 for fitting and fixing the plug body 4 and a knurl functioning as a detent for the plug body 4. 7 etc. are formed. Further, the plug body 4 has a cylindrical shape with a lid, and has on its inner peripheral surface an annular projection 8 which meshes with an annular projection 6 on the outer peripheral surface of the mouth 5 and a knurl 7 on the outer peripheral surface of the mouth 5. Is formed.

FIG. 3 shows a side view (partially sectional view) of the plug body 4 alone, and FIG. 4 shows a bottom view thereof. The upper end surface 10 of the plug body 4 has a spherical surface, and a central portion thereof is formed with a fine hole 11 for passing contents. Further, a male screw 13 is formed on the cylindrical outer surface 12 that smoothly continues from the upper end surface 10. A projection 14 is formed in a predetermined range from the end of the spiral of the male screw 13 (the lowermost portion) so that the female screw (described later) of the cap 2 can ride on. The protrusion height of the projection 14 is lower than the height of the crest of the male screw 13 and is a height at which the clearance between the cap 2 and the female screw is zero or in a crimped state. In the illustrated example, the external thread 13 is a double thread, and the protrusions 14 formed at one end of the spiral of each thread are symmetrical with each other about the axis of the pore 11 as shown in FIG. . In FIG. 4, the knurl 9 is only partially shown for convenience. However, the knurl 9 is actually provided on the entire inner peripheral surface of the plug body 4.

FIG. 5 shows a side view (partial sectional view) of the cap 2 alone, and FIG. 6 shows a bottom view of the cap 2. The cap 2 is a screw cap having a female screw 16 on the inner peripheral surface 15 for fitting with the male screw 13 of the plug body 4. At the center thereof, a needle-like projection 17 is provided for fitting into the pore 11 formed on the upper end face 10 of the plug body 4 to seal the pore 11. The diameter of the needle-like projection 17 is as thin as not exceeding 1 mm. In the illustrated example, the female screw 16 is a double-threaded screw like the male screw 13. The helical end of the female screw 16 of the cap 2 is moved to the position shown in FIG. 1 after the needle-shaped projection 17 starts fitting with the pore 11 when the cap 2 is screwed into the plug body 4. Until the cap 2 is completely screwed into the plug body 4 as shown, the cap 2 rides on the projection 14 of the male screw 13.

FIG. 2 is an enlarged view showing a state where one end of the spiral of the female screw 16 rides on a projection 14 provided on the male screw 13, whereby the cap 2 is pushed outward. At this time, both the plug body 4 and the cap 2 are slightly elastically deformed, and the projection 14 and the female screw 16 are in a crimped state. As described above, the male screw 13 and the female screw 16 are both double-threaded screws, and the projections 14 formed on the spiral end of the male screw 13 are located symmetrically with respect to the fine hole 11. When the cap 2 is screwed into the plug body 4, the timing at which the female screw 16 rides on these two projections 14 is simultaneous. Therefore, the needle-like projections 17 of the cap 2 are fitted after being aligned with the small holes 11.

When the gel-like content is squeezed out of the tubular container 1 and applied to the skin, the tubular container 1 is held by hand and the cap 2 is removed. Subsequently, while holding the upper end face 10 of the plug body 4 against the skin, the tubular container 1 is grasped with an appropriate force, thereby squeezing out an appropriate amount of the content from the pores 11 at the center of the upper end face 10. Then, the spherical upper end face 10 is rubbed against the skin, and the content is applied to the skin. That is, the upper end surface 10 of the plug body 4 functions as a coating surface for applying the contents squeezed from the pores 11, and the upper end surface 10 is only necessary for applying the contents. With area.

The operation and effect obtained from the embodiment of the present invention having the above configuration are as follows. First, the female screw 16 of the cap 2 rides on two projections 14 formed on the spiral end of the male screw 13 of the plug body 4, so that the play of the screw cap 2 with respect to the plug body 4 is reduced. Eliminate the gap between the male screw 13 on the cylindrical outer surface 12 of the plug body 4 and the female screw 16 on the cap 2, which causes the occurrence. Therefore, the play of the cap 2 with respect to the plug body 4 is forcibly eliminated. In addition, since the two female screws 16 ride on the two protrusions at the same time at positions symmetrical to each other with the hole 11 as the center, the play of the cap 2 with respect to the plug body 4 can be maintained while maintaining a balance in the circumferential direction. And the center of the cap 2 can be accurately aligned with the center of the plug body 4. In addition, the cap 2 can be prevented from loosening with respect to the plug body 4.

Moreover, immediately before the needle-like projection 17 is fitted to the small hole 11, the female screw 16 of the cap 2 starts to ride on the projection 14 of the male screw 13 and the cap body 4 shown in FIG. The needle-like projection 17 of the cap 2 is accurately positioned in the hole 11 provided at the center of the upper end face 10 of the plug body 4 until the screw is completely screwed in, and the hole 11 is sealed. Can be. The needle-shaped protrusion 17 has a low strength in shape, and if the positioning is not accurately performed, the needle-shaped protrusion 17 may be damaged by hitting the upper end face 10 and lose the hermeticity, but according to the embodiment of the present invention, Since the needle-like projections 17 are securely fitted into the fine holes 11, there is no risk of the fine holes 11 being damaged.

On the other hand, while the projection 17 of the male screw 13 does not fit on the projection 14 of the male screw 13, the female screw 16 of the cap 2 does not ride on the projection 14 of the male screw 13. At the initial stage of fitting, there will be no trouble such as hindering the screwing work and abrasion of the male screw and female screw in a short time. That is, centering by the projections 14 is performed only in a necessary range.

In the case of the tubular container 1 according to the embodiment of the present invention, the upper end face 10 of the plug body 4 has an area necessary for applying the contents, and the contents are applied. Since the container functions as a surface, the contents can be applied to the skin without using a finger or the like. However, since the upper end surface 10 of the plug body 4 has an area necessary for applying the contents, the diameter of the plug body 4 becomes relatively large. In this case, the distance between the fine hole 11 located at the center of the upper end surface 10 and the male screw 13 formed on the outer cylindrical surface 12 of the plug body 4 is increased, and the key for screw fitting with the male screw 13 is formed. The positioning accuracy of the needle-like projections 17 of the cap 2 with respect to the pores 11 is likely to be reduced. However, according to the embodiment of the present invention, the centering means for centering the cap 2 with respect to the plug body 4 by having the female screw 16 ride on the projection 14 of the male screw 13 is provided. Thus, such a decrease in positioning accuracy can be prevented, and the pores 11 can be reliably sealed.

Although not shown, the projection 14 constituting the centering means of the cap 2 with respect to the plug body 4 is replaced with a predetermined portion of the female screw 16 of the cap 2 instead of one end of the spiral of the male screw 13. It may be provided. The male screw 13 of the plug body 4 and the female screw 16 of the cap 2 may be provided on both. When both are provided, the sum of the height of the projection of the plug body 4 and the height of the projection of the cap 2 can be made the same as the height of the projection 14, so that the same centering function as described above can be provided.

Further, the male screw 13 and the female screw 16 can be formed as a multi-threaded screw. In this case, the cap 2 is fitted to the plug body 4 at a plurality of positions in the circumferential direction. The centering function can be further improved.

Further, a projection 14 for constituting the centering means of the cap 2 with respect to the plug body 4 is provided at an appropriate position on the plug body 4 at a distance from the male screw 13. The protrusion may be provided directly on the outer surface 12 of the plug body 4, and the protrusion may be provided at an appropriate position spaced from the female screw 16 of the cap 2. It is good also as making it contact | abut temporarily. In these cases, it is necessary to provide a projection with a position and shape that does not hinder the screw fitting of the male screw 13 and the female screw 16. There is an advantage that it can be easily applied.

In addition, when the plug body 4 and the cap 2 according to the embodiment of the present invention are used for a container provided with another squeezing mechanism instead of the tubular container 1, the same operation and effect can be obtained. Can be.
