DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tube container, and more particularly, to a tube container capable of easily opening the mouth of the container and closing the container with a cap.

[0002]

2. Description of the Related Art Conventionally, a nozzle portion formed at the mouth of a container body and a plug body for closing a nozzle hole formed at the tip of the nozzle portion are manufactured by integral molding and stored in the container body. There has been proposed a tube container that can be cut, removed, and opened when extracting the used drug solution or the like.
Such conventional tube containers include those shown in FIGS.

In FIG. 6, reference numeral 50 denotes a container body, and a nozzle portion 51 is formed at the mouth of the container body 50. And in the nozzle hole 52 of this nozzle part 51,
The plug 53 is integrally connected at the thin portion 56. The upper end of the plug 53 is fitted into a fitting hole 55 opened in the top surface of the cap 54 and is thermally welded. In such a tube container, when opening the nozzle hole 52 formed at the tip of the nozzle portion 51, the thin portion 56 is cut by twisting the cap 54 left and right with a finger,
The nozzle hole 52 is opened.

In the conventional tube container shown in FIGS. 7 and 8, a male screw portion of a mouth portion 61 of a container body 60 has
The female screw portion of the cap 62 is screwed. A plug 63 having a rectangular cross section and projecting upward is connected to the opening of the mouth portion 61 by a thin portion 64 to close the opening of the mouth portion 61. In such a tube container, when opening the mouth portion 61, the cap 62 is removed from the mouth portion 61, the cap 62 is inverted, and the engagement hole 65 of the cap 62 is fitted into the plug 63, By twisting left and right, the thin portion 64 is cut and the mouth 61 is opened.

[0005]

However, in such an invention, it is necessary to heat-weld the plug shown in FIG. 6 by fitting the tip of the plug 53 into the fitting hole 55 of the cap 54. Yes, it takes time to manufacture, and the cap 5
When the screw 4 is twisted, the welding between the plug 53 and the cap 54 is detached, and there is a disadvantage that the nozzle hole 52 of the nozzle portion 51 cannot be opened due to idling. 7 and 8 show that when the plug 63 is cut and removed, the cap 62 is unscrewed and the cap 62 is turned upside down. 65 has to be inserted and twisted to the left and right, and there is a disadvantage that the opening operation of the mouth portion 61 is very troublesome.

The present invention has been made in view of such a conventional problem, and does not require a separate step such as heat welding in a manufacturing process. Further, at the time of an opening operation, the stopper and the cap are detached. It is another object of the present invention to provide a tube container in which the opening operation is extremely easy without the possibility of idling and the cap is protected by a cap so that the plug is not accidentally broken.

[0007]

In order to solve this problem, according to the present invention, the tip of the plug is formed on the top surface of the cap so that the cap and the plug having a plurality of blades do not come off. The plug and the nozzle portion of the container body are formed integrally with each other through a thin-walled portion, easily cut,
A plurality of inner ribs screwed to the blade body of the plug are formed on the upper inner surface of the cap, and a plurality of abutting portions are formed on the inner surface of the cap lower portion so that the outer periphery of the nozzle portion engages with the cap. A tube container characterized by the following.

[0008]

Next, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a container body, and a nozzle portion 2 is welded to a shoulder 1a of the container body 1 by a method such as heat welding. In a nozzle hole 3 formed at the tip of the nozzle portion 2, a plug 4 is manufactured integrally with the nozzle portion 2 and is connected via a thin portion 5. And plug 4
A plurality of blades 4a (in this embodiment, 4
And a plurality of inner ribs 7 (four in this embodiment) formed on the inner peripheral surface of the cap 6 as shown in FIG. 3 (end view taken along the line AA in FIG. 2). Is formed so as to engage with the inner ribs of the first and second members.

The tip 4b of the plug 4 is fitted into a through hole 6a formed in the top surface of the cap 6, and a plurality of abutting portions 6b (under this embodiment) are provided below the cap 6. Are formed at three locations, and are engaged with the outer periphery of the lower end of the nozzle portion 2. The strength of the engagement between the contact portion 6b of the cap 6 and the nozzle portion 2 is such that the cap 6 is rotatable around the outer periphery of the nozzle portion 2.

Next, the operation of the present invention will be described.
First, the tip 4b of the plug 4 integrally formed with the nozzle 2
When the cap 6 is assembled, the tip 4b is press-fitted into a through hole 6a formed in the top surface of the cap 6,
The cap 6 and the plug 4 are integrated so as not to be detached. When extracting the contents, the nozzle 2 of the container body 1 is opened. That is, when the cap 6 is rotated in the left-right direction, the blade 4a of the plug 4 and the inner rib 7 of the cap 6 engage and rotate (see FIG. 3). The container body 1 and the nozzle portion 2 are held by hand, and the plug 4 rotates left and right, so that the thin portion 5 is twisted and cut. That is, the cap 4 and the cut plug 4 have the distal end 4 b in the through hole 6.
a, the cap 6 and the plug 4 are removed from the nozzle 2 as shown in FIG.
Is opened.

Next, when the nozzle portion 2 is closed after extracting the contents, a cap 6 is put on the nozzle portion 2. Then, by inserting the cut lower end of the plug 4 into the nozzle hole 3 of the nozzle portion 2, the nozzle hole 3 is re-closed and, as shown in FIG. 6 is brought into contact with the contact portion 6b. Then, the cap 6 is fixed to the outer periphery of the nozzle portion 2. Thereby, the hermeticity of the container body 1 is maintained.

[0012]

As described above, according to the present invention, a separate step such as heat welding is not required in the manufacturing process, and the plug and the cap are separated during the opening operation, so that the idling is performed. There is no danger. In addition, the opening operation is extremely easy, and the plug is protected by the cap, so that the plug is not accidentally broken.
