Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a structure for engaging and assembling a tube container body and a cap 2 in a tube container for storing viscous contents.

[Prior Art] In a conventional tube container for storing viscous contents,
As shown in FIG. 6 and FIG. 7, the assembly of the container body and the cap is such that the circumferential projection 5 is formed over the entire circumference of the container body head 3 and the circumferential projection is formed over a wide area of the inner surface of the cap 2. This is achieved by providing a locking strip 6 that locks to 5.

[Problems to be solved by the device]

In such a conventional technique, when the remaining amount of the content becomes low, the container body 1 is pressed from the lower part to the upper part with the cap 2 kept closed to facilitate the pouring of the content. In many cases, the cap 2 is collected on the head 3, but at that time, the cap 2 is detached from the container body 1 and flies by the pressing force on the container body 1.

When the upper end of the body 7 of the container body 1 is pressed,
As shown in the figure, the head 3 of the container body 1 is also elastically deformed by the pressing force, and the peripheral ridges 5 (portions indicated by imaginary lines) located at the front and rear portions of the lower end of the head 3 are largely displaced downward. This is because the circumferential projection 5 and the locking strip 6 that has been locked are released, and at the same time, the cap 2 flies due to the elastic force when the two are released.

The present invention was made in view of these problems, and an object thereof is to provide a tube container in which the cap 2 does not come off and fly even when the container body 1 is pressed to collect the contents in the head 3. And

[Means for Solving the Problems]

Therefore, the tube container main body 1 in which the lower end portion for accommodating the viscous contents is flatly sealed in the front and rear direction has a flat shape in the front and rear direction. A locking strip 6 is formed on the lower end portion of the inner peripheral surface of the cap 2 which forms the strip 5 and is fitted to the head and has an elliptical shape in plan view which is the same as the head 3. Was formed.

[Action]

In order to collect the contents in the container body 1 head 3, the container body 1
Is pressed in the front-back direction (because the container body 1 is flatly sealed in the front-back direction, the pressing is necessarily performed in the front-back direction), as shown in FIG. The front and rear portions of the portion are largely displaced downward because the body portion 7 of the container body 1 which is immediately below the front portion is crushed. However, the right and left sides of the head 3 are hardly displaced downward because the portions directly below are not crushed.

In the present invention, since the circumferential ridges 5 are provided on the left and right sides of the lower end of the head 3, the inclined wall 4, the circumferential ridges 5 are hardly displaced downward even when the container body 1 is pressed in the front-back direction. Has become. (In FIG. 5, the circumferential ridge 5 according to the present invention is shown by a solid line, and the circumferential ridge 5 according to the prior art is shown by an imaginary line.
This clearly shows the difference in the amount of downward displacement between the two. Therefore, in the present invention, the engagement of the circumferential projection 5 with the locking projection 6 that is locked to the circumferential projection 5 is always reliably achieved regardless of the pressing force acting on the container body 1. It is something.

〔Example〕

One embodiment will be described with reference to FIGS. 1 to 4.

This is one in which a synthetic resin head 3 is erected on the upper end of a container body 1 body part 7 composed of a synthetic resin laminated body using an aluminum foil on the inner surface, and stores butter, margarine, etc. It is a tube container. The container body 1 body portion 7 has an elliptical cross section, and the head portion 3 also has an elliptical shape corresponding to the body portion 7.

The head 3 is formed by an inclined wall 4 having a flat upper end, and the lower end of the inclined wall 4 is a vertical wall 8. Three small openings 9 are formed at the upper end of the head 3, and the contents are poured out from the openings 9 by pressing the container body 1.

The circumferential ridges 5 are formed on the left and right upper ends of the vertical wall 8 which is the lower end of the inclined wall 4. The circumferential length of the circumferential ridge 5 is greatly lowered when the container body 1 is pressed. It is formed in a range that does not displace. Further, two locking projections 6 are formed on the lower end of the inner peripheral surface of the cap 2 for locking the circumferential projections 5, two small projections left and right. A total of four vertical strips 10 are formed in the longitudinal direction on the front and rear portions of the inner peripheral surface of the cap 2, and the vertical strips 10 are brought into contact with the vertical wall 8 at the lower end of the head 3 to form the cap 2. The assembly with the head 3 is stable.

[Effect of device]

As described above, the present invention forms the circumferential projections 5 on the left and right sides of the lower end of the head 3 of the tube container body 1, the inclined wall 4, and
Since the locking ridge 6 for locking the circumferential ridge 5 is formed at the lower end of the inner peripheral surface of the cap 2, the circumferential ridge 5 is hardly displaced downward even when the container body 1 is pressed in the front-back direction, and thus the cap is capped. It is possible to always achieve strong and stable assembly without the engagement assembly with the two locking strips 6 coming off.
