Description

Container Cap {CAP}

The present invention relates to a closure of a container, and more particularly, to contain an additive of a different kind from the contents stored in the container to the container stopper, and to allow the additive to be introduced into the container through the opening of the isolated space, if necessary. It relates to a container closure that allows two different materials to be mixed.

Currently, most containers in the market are distributed and sold, with only one substance stored in one container. However, there is a need to mix and use two different types of materials to satisfy user's preference diversity. For example, in the case of coffee beverages may be mixed with sugar or cream powder in the coffee beverage, such as in the case of medicines or chemicals can be described.

However, in the related art, when a mixture of two different materials is used, there is a need to separately purchase a container containing each material. Particularly, in case of a substance requiring accurate mixing ratio, a metering mechanism is additionally required for mixing the substance.If a measuring instrument is not provided, there is a problem such as poor product characteristics or inability to use the product due to poor mixing ratio. It was accompanied.

Therefore, in accordance with such a trend, container caps for different materials have recently been provided. However, the conventional structure has various problems because the additive receiving space is substantially exposed to the outside or does not maintain sufficient airtightness. That is, the container has a problem that the fluidity is greatly changed by the change of the external temperature according to the characteristics of the contents, and when the airtight performance is not good, the internal pressure increases and leaks. Especially, the airtightness is accompanied by long-distance transportation or seasonal change. Since the additives are closely related to the deterioration at the time of storage for a long period of time, there is increasing interest in the sealed structure of the additive receiving space.

Accordingly, the present invention has been proposed to solve the above problems of the prior art, the object of which is to separate and accommodate the additive material to be mixed in the receiving space provided in the container cap and to open the receiving space at the same time as the opening of the plug is added The purpose of the present invention is to provide a cap of a container which can be effectively added to the container by being added into the container.

Another object of the present invention is also to maintain a good airtight inside the receiving space to accommodate the additive to replace the change in the internal pressure, to prevent the deterioration of the additive, such as during long-distance transport and long-term storage, furthermore, vapor or gas generated from the contents The purpose of the present invention is to provide a closure of a container that can prevent the back from penetrating into the additive containing space.

First, the initial state is maintained as shown in FIG. 4A. Holding the main cap 320 in this state and rotating in the opening direction is the storage member 300 is rotated. Therefore, when the blade portion 252 penetrates the cutting wall 362 and enters the receiving portion, and the cutting wall 362 is cut by the blade portion 252 and enters a predetermined depth, the bottom surface of the receiving portion is shown in FIG. 4B. That is, the tear portion 340 is cut by the blade portion 252. At this time, the rupture portion 340 is guided downward along the guide portion 254 at the same time as the incision as shown in Figure 3B proceeds through the bottom surface of the pressing unit 256 is smoothly made. At this time, since the storage member 300 makes a spiral movement, the predetermined distance is increased according to the rotation, so that the height of the bursting portion 340 pressed by the pressing portion 256 is gradually increased, so that the broken portion 340 is sufficiently opened. You lose.

On the other hand, if the process continues as described above, as shown in FIG. 4C, the protrusion 366 is cut by the blade portion 252 and pressed by the pressing portion 256 at the same time. At this time, since the protrusion 366 enters the bottom of the pressing part 256 by the inclined surface 366a and is rapidly pressed, the rupture part 340 is based on an uncut portion, that is, a lower portion of the support wall 364. Thus, the already cut portion is sufficiently opened to the lower portion to be in a state as shown in FIG. 5, and the additive of the accommodation portion is introduced into the container body 100.

In such a state, when the storage member 300 is further rotated, the outer locking protrusion 324 contacts the outer protrusion 222 at a predetermined position, and at the same time, the inner locking protrusion 332 also touches the inner protrusion 224 to open the member ( Separation is made from the inlet 110 with the 200.

6 and 7 show the configuration of the second embodiment of the container closure according to the present invention. It discloses that the cutting member is configured on the side of the opening member 200 so that the side of the receiving portion 330 is cut when the storage member 300 rotates. This is distinguished from cutting the bottom of the receiving portion as in the first embodiment of the present invention. The same components as in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

According to this, the immersion portion 360 is formed in the lower portion of the storage member 300 to be recessed radially inward, and the cutting member 250 is inserted into the immersion portion 360 at the lower end of the opening member 200 It is constructed integrally.

The blade portion 262 is disposed in the horizontal direction and is inclined with respect to the cutout wall 362. In the second embodiment having such a configuration, when the storage member 300 is rotated, the blade portion 262 is gradually contacted from the outer end portion of the cutout wall 362 to initiate the cutting of the receiving portion 330 side, and gradually the inner side. Incision proceeds to the end and the lower end side of the receiving portion 330 is cut by the blade 262. At this time, since the cut portion is gradually opened by the pressing portion 264 behind the blade portion, discharge of additives is performed at the same time as the cut portion. Since the rotation of the storage member 300 is accompanied by an upward movement due to the spiral movement, the position where the support wall 364 and the blade portion 262 contact each other is lower than the position where the cutting wall 362 contacts. Therefore, the rupture part 340 is deformed to the lower part based on the portion of the cutout portion, that is, the cutout portion 362 and the support wall 364, and the additive is discharged.

The subsequent operation is the same as in the first embodiment.

According to this embodiment, the discharge of the additive can be achieved in a relatively simple structure, and it is easy to maintain the structural strength of the blade.

8 shows a configuration of a third embodiment of the present invention. It discloses a structure for easily forming and assembling the blade portion.

According to this, the container body 100, the male thread 112 is formed on the outer side of the injection port 110, the opening member 500 is detachably coupled to the container body, and screwed to the injection port 110 at the same time A main cap 600 supporting the opening member 500, a storage member 700 which is screwed to the main cap 600 and interacts with the opening member 200, and an upper portion of the storage member 700. The upper cap 800 is opened and closed.

The opening member 500 has a cylindrical shape, each of which is opened at the top and bottom thereof, and a plurality of locking protrusions 502 protrude from the upper inner side thereof, and a cutting member 250 is integrally formed at the lower end thereof.

The main cap 600 has a flange 610 having a through hole 612 in the center portion, the female screw 620 and the storage member 700 are screwed to the injection hole 110 on both sides of the flange 610, respectively. The female screw 630 is screwed to the formed. A connecting pipe 640 including a through hole 612 protrudes in the axial direction at the center of the flange 610, and the locking protrusion 502 is coupled to the periphery of the connecting pipe 640 to rotate the opening member 500. A plurality of locking grooves 642 for limiting the width are formed.

On the other hand, the storage member 700 includes a cylindrical receiving portion 710 is inserted into the lower through the through hole 612 and positioned inward in the opening member 500, the upper portion is open to the upper cap ( 800 is configured to screw. In the center portion, a male screw 720 is screwed to the female screw 630 of the main cap 600 is formed.

The lower portion of the receiving portion 710 is formed with an immersion portion 360 is formed recessed in the radial direction, the lower end of the opening member 500 is formed integrally with the cutting member 250 is inserted into the immersion portion 360 It is. The configuration of the immersion part 360 and the cutting member 250 are the same as those of FIGS. 3A and 3B described in the first embodiment of the present invention, and thus detailed illustration and detailed description thereof will be omitted.

In the third embodiment having such a configuration, when the storage member 700 is rotated in a coupled state as shown in FIG. 9, the storage member 700 is rotated by a screw action with the main cap 600 to achieve an elevation. Therefore, the blade 252 cuts through the incision wall 362. In this case, the opening member 500 maintains a state in which the rotation of the main cap 600 is restricted because the locking jaw 502 is caught in the locking groove 642. Since the following operation is the same as in the first embodiment, detailed description thereof will be omitted. In addition, since the storage member 700 is rotated about 320 to 350 degrees, the bottom surface is sufficiently opened, so that the user can sufficiently input the additive by rotating the storage member 700 once. In this case, in the state where the storage member 700 makes one rotation, the mixture is not leaked to the outside even when the container body 100 is shaken to mix the additive and the contents contained in the container body.

After the addition of the additives is completed in this way, if the main cap 600 is opened, the main cap 600 is separated from the inlet 110 and at the same time the opening member 500 is also simultaneously separated to drink through the inlet. Of course, the main cap 600 can be used, such as drinking and straw in the open state without opening the upper cap (800).

 In this third embodiment, since the opening member 500 and the main cap 600 form a separate structure, the cutting member 250 and the immersion part 360 expected when the opening member 500 and the storage member 700 are assembled. The difficulty in securing the correct position of) is solved. That is, when the storage member 700 is screwed on the upper portion of the main cap 600 first, the opening member 500 enters the lower portion while the position of the immersion part 360 and the cutting member 250 are aligned. By assembling the 502 and the locking groove 642 is assembled without difficulty.

Meanwhile, according to the present invention, as shown in FIG. 10, it is preferable to additionally install the aluminum cap 900 surrounding the upper cap 800, the storage member 700, and the main cap 600. That is, the upper cap 800, the storage member 700 and the main cap 600 is made of a synthetic resin material is less effective in blocking sunlight from the outside. Therefore, it is possible to prevent the risk of deterioration of the additives by adding an aluminum cap excellent in the sun blocking effect. Such an aluminum cap is of course applicable in the first to second embodiments of the present invention.

The technical idea of the closure of the container according to the spring invention is not limited to all the embodiments described above, it should be understood to include those that can be implemented by interchangeable combinations and simple structures of the embodiments and the like.

For example, in the embodiment, although one place is provided over the 360 degrees of the immersion part and the cutting member, there is a configuration in which two are provided at intervals of 180 degrees. This can improve the ease of cutting and can be deformed courageously by those skilled in the art.

As described above, the present invention, by cutting the rupture portion by the rotation of the opening member so that the additive is introduced into the container, it is possible to effectively seal the additive receiving space, so that it effectively copes with the internal pressure according to the temperature change of the additive It prevents leakage, prevents oxidation and decay of additives, and improves storage performance in long distance transportation and long-term storage.
