The present invention relates to a coupling structure of the cap coupled to the discharge port of the tubular container for storing the liquid or gel contents, such as cosmetics, in particular by changing the structure inside the cap, the first spiral of the cap when capping the cap and tube It prevents the phenomenon of jamming when the part meets the first part of the discharge spiral of the tube and prevents the cap from being opened during capping work or when filling the container or moving inside, and the slip-proof structure part can be molded at the upper side of the inside of the cap. The present invention relates to a coupling structure of a tube container and a cap to be applicable to both a short cap or a double cap.

In general, in order to seal a container for storing various contents consisting of liquid or gel or solid phase, a cap screwed by a cap having a threaded portion is usually used.

The cap is divided into short cap (single cap) and double cap (double cap). In the case of the short cap, a screw is formed on the inner circumference of the cap, and the screw and the container can be coupled to the discharge section. While having a structure of an inner cap spaced apart from the outer cap, a screw is generally formed on the inner circumferential surface of the inner cap so as to be screwed with the discharge port of the container.

These short caps and double caps (hereinafter, collectively referred to as caps) are usually injection molded using synthetic resin. In order to prevent the caps from turning when they are injected into the shape of the caps from the injection machine, the caps protrude finely on the lower side of the inner circumference of the caps.

Is discharged through the upper discharge hole 142, it is to be used by the user.

Second Example

This embodiment, unlike the first embodiment described above, means that the short cap 100 'is formed, which means that there is no inner cap 101.

This short cap 100 ′ is as shown in FIGS. 6 to 10.

The short cap 100 ′ is a semicircular slip prevention device 110 at the lower end of the inner circumferential surface is spaced at regular intervals, and short guide guide groove 120 having a curved surface in succession to the upper end of the slip prevention device 110 (100 ') was formed in the form of a band along the inner circumferential surface, it is connected to the upper surface of the guide groove 120 to form a screw portion (130).

Meanwhile, the container 200 corresponding thereto is illustrated in FIG. 7.

As shown in the drawing, the container 200 has a structure in which heterogeneous contents are filled inside, as in the first embodiment, and two discharge holes 212 are formed on the upper surface of the discharge port 210 of the container 200. It is formed, it is a structure in which the other two kinds of contents are discharged through the discharge hole 212 in use.

The discharge port 210 of the container 200 is screwed to the threaded portion 130 formed on the inner circumferential surface of the end cap 100 ′ according to FIG. 6, corresponding to the guide groove 120 at the lower end of the discharge port 210. A protrusion 213 having a shape to be formed is integrally formed along the circumferential surface.

FIG. 8 is a view illustrating a state in which the discharge port 210 of the container 200 and the short cap 100 'are screwed together.

9 illustrates a process of combining with the discharge port 210 using the short cap 100 'as described above, and when the short cap 100' is coupled, a round semi-circular shape is formed at the lower end of the inner surface thereof. The slip prevention device 110 passes over the protrusion 213 formed on the outer circumferential surface of the lower end of the discharge port 210 of the container 200. (See the enlarged view of FIG. 9.)

As described above, after the lower end of the short cap 100 'is expanded and has a stiff feeling, when the screw parts 130 and 220 are completely coupled, the lower end side of the short cap 100' is as shown in FIG. 8. The slip prevention hole 110 formed in the container 200 is fastened after passing through the protrusion 213 protruding downward from the discharge port 210, and the protrusion 213 is lower than the short cap 100 ′, that is, slip. The coupling between the end cap 100 ′ and the discharge port 210 of the container 200 may be completed by being inserted into the guide groove 120 formed directly above the prevention tool 110.

After the coupling between the short cap 100 ′ and the container 200 discharge port 210 is completed as described above, when the short cap 100 ′ and the container 200 are separated as necessary, as illustrated in FIG. 10. It can be separated by going through the reverse process of one process.

On the other hand, the above-described example has been described by applying the short cap (100 ') in the case of Figure 11 may be possible to implement using the double cap (100).

As shown in FIG. 11, the cap shown in FIG. 11 is a double cap 100, unlike the double cap 100 in the first embodiment, that is, in order to be combined with the discharge port 210 of the container 200 of the present embodiment, that is, the discharge port 210. An elastic force is required in order to fit the slip preventing device 110 in the lower side of the protrusion 213, and for this purpose, the inner side of the cap 101 is extended from the lower end side but is formed at equal intervals. The slip preventing device 110 protrudes toward the lower end of the inner circumferential surface of each of the unit pieces 102, and extends upwardly to the upper surface of the slip preventing device 110 to form a guide groove 120 having a curved surface. It was.

As such, when the inner cap 101 formed of the unit piece 102 is combined with the discharge port 210 of the container 200, the lower end of the unit piece 102, that is, the slip prevention port 110, is formed at the lower end of the discharge port 210. When slipping over the protrusions 213 protruding to the outer circumferential surface, each of the unit pieces 102 elastically slides outward in order to secure flexibility, and then the slip preventing holes 110 are positioned below the protrusions 213. When the unit piece 102 is returned to its original shape again, the slip preventing device 110 is caught by the protrusion 213 and guide grooves 120 are formed for each unit piece 102 as described above. As such, the protrusion 213 of the discharge port 210 may be inserted and fixed.

The position where the protrusion 213 is fixed as described above is a position at which the coupling between the inner cap 101 and the threaded portions 130 and 220 of the discharge port 210 is completed, and the upper surface of the discharge port 210 of the container 200. The contents discharged from the discharge hole 212 provided in the is in a position to be easily guided to the spiral mixing screw 141 side.

Third Example

On the other hand, in the case of utilizing the double cap 100 and the short cap 100 'according to the first and second embodiments described above, the two types of contents filled in the container 200 are described in the first and second embodiments. In the helical mixing screw 141 of the extension discharge port 140 provided inside the double cap 100 and the short cap 100 ', two types of contents are first mixed and then completely mixed by the user. On the contrary, in the third embodiment, the cap is fastened to the container 200 filled with two kinds of contents which are not preferably mixed in the double cap 100 or the short cap 100 ', that is, the spiral mixing screw 141. It is to apply in the case.

For example, this may be the case with hair dyes.

In the case of hair dye, the first agent and the second agent are mixed at an appropriate mixing ratio, respectively, and applied to the hair to be dyed for a predetermined time, and when the first agent and the second agent are mixed at the above-mentioned discharge outlet 140, they are extended upon reuse. The mixture of the first agent and the second agent that caused the reaction is accommodated in the discharge port 140, so that the dye may not be reused.

Therefore, in the case of hair dye, even if one container 200 is filled with the medicine of the first agent and the second agent, the double cap 100 or the short cap 100 'may not be mixed with the user in a completely discharged state. It is preferred to be mixed by.

In order to apply the double cap 100 or the short cap 100 ′ for the above application, it is preferable to apply the cap structure of FIGS. 12 to 16.

12 is shown and described by applying only the double cap 100 in the present embodiment, it is not applied only to the double cap 100, it is of course also applicable to the short cap (100 ').

13 to 14, it is preferable to form a partition plate 143 partitioning the inside of the extension discharge port 140 extending from the upper end side of the inner cap 101 of the double cap 100, the partition plate 143 By discharging the discharge hole 142 above the extended discharge outlet 140 into two holes, the inside of the extended discharge outlet 140 is also divided into two spatial regions.

The partition plate 143 is configured to be effective only in the region inside the extension discharge port 140, that is, the bottom side of the partition plate 143 is configured to match the position of the lowest end side of the extension discharge port 140, double cap When the complete screw coupling between the inner cap 101 of the 100 and the discharge port 201 of the container 200 is completed, the lower end of the partition plate 143 and the upper surface of the discharge port 201 are brought into contact with each other.

In addition, the two space areas partitioned by the partition plate 143 are positioned so that the two discharge holes 212 open to the upper surface side of the discharge port 210 correspond to each space area.

On the other hand, a means for such positioning is required.

To this end, as shown in FIGS. 13 and 15, a positioning protrusion 160 protruding at two positions opposed to the inner circumferential surface of the lower end of the inner cap 101 of the double cap 100 is formed, and correspondingly. The positioning protrusions 230 for fitting the above-described positioning protrusions 160 to the outer circumferential surface of the lower end of the discharge port 210 of the container 200 are configured.

As shown in FIG. 15, the position fixing part 230 is configured to have a groove 231 therein, such that the positioning protrusion 160 is inserted into the groove 231.

On the other hand, in order to prevent the positioning protrusion 160 from being easily inserted into the groove 231 after being inserted and removed, the position fixing part 230 of one side forms a fan shape when viewed in a plane and the inside is straight. It is preferable to prevent the positioning protrusion 160 from being separated in the state where the positioning protrusion 160 is positioned in the groove 231, and it is possible to easily ride the position fixing part 230 in the process of being fitted into the groove 231. It is desirable to round it.

When the discharge holes 212 are placed in corresponding positions between the spaces partitioned by the partition plate 143 in this way, even if the inner contents of the container 200 are squeezed out, the discharge holes 212 are partitioned inside the short cap 100 '. Although the contents are discharged from the two discharge holes 212 which are perforated to the upper surface side of the discharge port 210 of the container 200 by the partition plate 143, the contents inside the extended discharge port 140 inside the short cap 100 '. While preventing the mixing, each of the contents are separately discharged through the two discharge holes 142 formed in the extension discharge port 140, it can be used by the user mixed.

Such use may be facilitated in the case of the hair dye as described above, as described above may be of course applied to the double cap 100 as well as the short cap (100 ').
