At the bottom of the container which is fixed to the locking projection at the bottom of the inner cap and the additive of the slider is added to the inside of the container, the bottom cap which blocks the slider is made into a tubular shape with the top closed, and is fixed to the locking projection of the inner cap with a sealing ring and a hook on the side wall. It is easy to assemble by placing the contraction guide groove which functions to reduce the outer diameter when assembling by touching the hooking protrusion on the hook part to facilitate the initial assembly, and the bottom cap and the inner cap are not separated by the fixing force of the hook. It relates to the closure of the container to maximize the safety by acting.

The present invention also has a storage member which is a lower cap having a discharge port to the inner side of the lower end of the tubular inner cap to be inside the inlet of the container, an opening member having a slider having an additive container function guided to the inner cap inner diameter, and blocking the lower end of the slider. In the stopper of the container consisting of a bottom stopper, which is separated from the time slider,

The bottom cap is inserted into the end of the inner diameter of the slider 536, and inserting the function to block the inner diameter,

A sealing ring extending in the direction of the insert end side to seal the lower end of the slider,

The upper edge of the insert includes a stop bar protruding obliquely in the direction in which the diameter of the insert increases, and relates to a stopper of the container to prevent reuse.

In general, the closure of the container has been developed from a simple closure function to a stopper that can be used by adding an additive. An example is PCT published pamphlet (WO2005 / 051775), an exploded perspective view showing the technical configuration related to Figure 1 and a cross-sectional view illustrating the coupling process in Figure 2, Figure 3 is a longitudinal cross-sectional view 4 is a cross-sectional view showing a process in which an additive is added to FIG. 4 and a ball-in cross-sectional view showing a separated state after the additive is added to FIG.

A container body 510 having an injection hole 511 having a male screw 512 formed on the outer circumference of the container, and a storage member 520 detachably inserted into the injection hole 511, and a storage member 520. ) Is coupled to the screw and rotates to separate the stopper to release the additive and at the same time interfere with the storage member at a predetermined position is composed of an opening member 530 to separate the storage member 520 from the injection port 511.

The storage member 520 has a cylindrical end plate 522 formed at the open end of the injection hole 511 and an female screw extending axially from the outer circumference of the end plate 522 and screwed to the injection hole 511. 524a is formed integrally with the main cap 524 and the inner cap 526 extending axially from the inner circumference of the end plate 522 and axially movable inwardly of the inlet 511. do. The lower end of the inner cap 526 has a locking projection 526b protrudes in the radially inward direction, and the outlet 540 is formed inward of the locking projection 526b. A male screw 524b is formed on the outer circumference of the main cap 524, and a stopper 522a that extends in the radial direction to limit the detachment of the opening member described later is integrally formed at the peripheral portion of the end plate 522.

Opening member 530 is a disk-shaped closing plate 532 and the female screw 534a is formed to extend in the axial direction from the outside of the closing plate 532 to the male screw 524b of the main cap 524. The upper cap 534 and the slider 536 which is spaced apart from the upper cap 534 extends in the axial direction from the closing plate 532 is inserted into the inner cap 526 is integrally formed.

A stopper 540 for sealing the inside of the slider is detachably coupled to the lower end of the slider 536. The stopper 540 is integrally formed with a hook 544 that forms a locking jaw 542 that is caught by the locking protrusion 526b at a lower end thereof. In addition, a seal protrusion 546 is formed on the top of the stopper 540 to be fitted to the seal groove 536b formed at the lower end of the slider 536.

In this case, in the initial state as shown in FIG. 2, the opening member is inverted in advance and the upper and lower sides are changed so that the slider exposed to the upper portion is filled with liquid or powdery additive (a1) and the seal groove 536b is previously closed. In the state in which the seal protrusion 546 is coupled, the opening member 530 is sequentially coupled with the storage member 520 as shown in FIG. And when the hook 544 is caught by the engaging projection (526b) and fixed as shown in Figure 3 to complete the assembly. In this case, since the tip of the hook 544 is tapered, the stopper 540 smoothly passes through the locking protrusion 526b and is firmly coupled to the locking jaw 542. In this state, when the opening member 530 is rotated, the opening member 530 is raised by the interaction of the male screw 512 and the female screw 524a. At this time, the stopper 540 is restricted by the locking protrusion 526b, so that the slider 536 is separated from the stopper 540 as shown in FIG. 4, and the additive is inside the container body 510 through the outlet 526a. Is put into.

Then, when the opening member 530 is continuously rotated, the female screw 534a is caught by the stopper 522a, so that the rotational force of the opening member 530 is transmitted to the storage member 520. Therefore, the storage member 520 is the female screw 512a of the main cap 512 and the male screw 512 coupling portion of the injection hole 511 is rotated, as shown in Figure 5 the storage member 520 and the opening member ( 530 is integrally separated from the inlet 511.

However, this structure is easy to combine and has a good sealing property, but because it forms a combined state by the inner diameter portion of the inner cap that is fitted into the interior of the container causes deformation and deformation during heat treatment for disinfection and sterilization. If you drink the contents after removing the opening member may be separated from the inner cap with the contents.

In addition, the stopper formed on the inner end of the inner cap by engaging the stopper and the hook of the stopper is cracked in the inner cap due to the forced coupling, so that when the user drinks the contents, the stopper falls out and the user's neck with the contents There is often a problem.

In another technique, as shown in FIGS. 6A to 6C, the inner cap 526 is inserted into the inlet of the container body 510 and has a stopper 540 at the bottom of the inner cap 526. A storage member 520 having an outlet 526a on an inner side thereof;

It is coupled to the storage member 520 and coupled to the inner cap inner diameter, and when combined, the lower end is sealed with a stopper 540, the container function of receiving the additives 536, the slider 536 of the container body coaxially The configuration consisting of an opening member 530 having an upper cap 534 screwed to an outer diameter portion of the inlet 511 is known from Japanese Patent Laid-Open No. 2006-44691 and Korean Patent Application No. 10-2008-0036319. This allows the slider 536 of the opening member 530 to open upward as shown in FIG. 6C, then fills the additive a1, and also changes the storage member 520 shown in FIG. 6B upside down (FIG. 5). As shown in FIG. 6D, the end of the slider 536 is blocked by a stopper 540.

The contents are placed in the container body 510 in such a manner that the upper and lower sides are reversed again, and then the capping is completed at the inlet 511 of the container body 510. Of course, in use, when the upper cap 534 is turned to loosen the screw, the sealing of the slider 536 and the stopper 540 is released, and the additive a1 is discharged into the container body 510 through the discharge port 526a to store the additive. Add to the contents to drink. Of course, in this case, the opening member 530 and the storage member 520 are integrally separated. 1 to 5 are denoted by the same reference numerals and description thereof will be omitted.

However, this technique separates the storage member 520 and the opening member 530 from each other in the separated state because the storage member 520 and the opening member 530 are separated together in the container body, and a new additive to the opening member 530. After arbitrarily inserting and re-combining with the storage member 520, when coupled again to the inlet of the container body 510 has a fatal problem that can be reused.

The present invention is to solve this, an object of the present invention is to block the opening member and the lower end of the slider having a storage member having an inner cap coupled to the container, and an upper cap having a slider of the additive receiving container function combined with the storage member In the stopper of the container to assemble, in use, the additive of the slider is added to the inside of the container by combining and separating with the bottom stopper fixed to the locking projection at the bottom of the inner cap,

An example of the bottom cap 550 of the present invention includes an insertion part 556 that is inserted into an inner diameter of the slider 536 and functions to block the inner diameter as shown in FIGS. 7A and 7B.

A sealing ring 551 extending to the lower side of the insertion part 556 to seal the lower end of the slider 536,

An extension tube 557 having a shrinkage guide groove 554 extending at the bottom of the sealing ring 551 and longitudinally cut at least one place such that the diameter thereof becomes smaller, and the outer diameter of the extension tube 557 is increased in the outer diameter direction. It comprises a hook 553 to protrude to the bottom of the locking projection (526b) of the inner cap lower inner diameter.

As shown in FIG. 7, a sealing groove 552 having a predetermined depth is formed between the upper surface of the sealing ring 551 and the inserting portion 556, and a sealing dowel wheel coupled to the lower end of the corresponding slider 536 in a fitted state ( 536a).

7C is the same as that of FIG. 7B, but the auxiliary locking protrusion 526c is added to the lower portion of the locking protrusion 526b of the inner cap 526 as shown in FIGS. 8 and 9.

The corresponding extension pipe 557 is configured to add an auxiliary hook 555 which is engaged by the auxiliary locking projection 526c and acts to increase the fixing force.

When using this, FIG. 7B acts as shown in FIG. 7A, and FIG. 7C acts as shown in FIGS. 8 and 9.

That is, when used as shown in Figs. 7 and 10, at the time of initial bonding, the slider 536 is turned upside down as shown in Fig. 10A, and the additive (additive (a1) that can be selected from liquid, powder, or granular form) is inserted and Fig. 10B. As shown below, the bottom cap 550 is used. Then, the insertion portion 556 of the bottom cap 550 on the inner diameter of the lower end of the inner cap 526 is coupled to the inner diameter of the slider 536 in a compressed state while passing through the curved portion 556a. Then, the sealing protrusion 552 of the lower end of the slider 536 to the sealing groove 552 of the sealing ring 551 at the same time to finish the fitted state to maximize the sealing property.

Then, the inverted opening member 530 up and down and press the bottom member 550 in the longitudinal direction of the inner diameter of the inner cap 526 of the storage member 520 as shown in FIG. The hook 553 of the first contact the upper surface of the locking projection (526b) protruding to the inner side of the lower inner cap 526, but resists the lowering, but the contraction formed in the extension tube 557 extending to the lower end of the bottom cap 550 By the guide groove 554, the outer diameter of the hook 553 portion is reduced to act to pass through the inner diameter of the locking projection (526b). This is because even if the hook 553 is formed on the outer diameter of the extension tube 557, the outer diameter is reduced to less than the inner diameter of the locking projection 526b, thereby causing assembly without cracking of the inner cap 526.

When the opening member 530 and the storage member 520 are assembled together with the bottom cap 550 in a state of being capped and shipped, the opening member 530 is opened as shown in FIGS. 7A, 8 and 10E. Since it is separated from the storage member 520 coupled to the container body 510, the additive contained in the slider 536 is added to the inside of the container body 5120 through the outlet 526a. When the opening member 530 is separated in this way, the bottom stopper 550 has a male screw 524b of the extension tube 527 because the locking protrusion 526b engages in the space caused by the sealing ring 551 and the hook 553. When the opening member 530 is rotated to loosen the screw, the opening member 530 rises and the slider 536 is separated from the bottom stopper 550 fixed to the bottom, thereby acting to add an additive therein into the container body. In this case, the bottom stopper 550 forms the sealing ring 551 and the hook 553 at the outer diameter portion of the extension pipe 557, and the locking protrusion 526b is placed in the space therebetween, so that the hook 553 of the hook 553 is engaged. Since the outer diameter is not reduced to maintain a strong fixing force the bottom cap 550 is not separated, so that the user can safely drink the contents of the container.

7c constitutes a configuration in which two hooks 553 and 555 are formed on the extension tube 557, and two locking protrusions 526b and 526c are formed on the inner cap 526, thereby preventing them from being separated when used. Maximize the action and the same action is also omitted.

However, as shown in FIG. 9, the auxiliary catching protrusion 526c has a longer protruding length than the catching protrusion 526b, and the hook 553 has a shorter length than the auxiliary hook 555, so that the auxiliary catching protrusion 555 is sequentially stopped by the lower short auxiliary hook 555. 526b and 526c to allow the initial coupling, and if necessary, to receive the contraction action force of the shrinkage guide groove 554 to reduce the outer diameter is coupled.

However, when combined to separate after use when combined, the bottom plug 550 'acts as a coupling, but not possible to separate the opening member 530 after the separation of the contents when drinking the contents that the bottom plug is separated Prevents maximization of stability. 11, 12, and 14 as shown in Figure 14, the bridge 528 of a predetermined depth at the bottom of the locking projection 526 formed on the inner wall of the end of the inner cap 526 of the storage member 520 as shown in FIG. The bridge 528 may have a bridge rib 529 formed to have a predetermined depth so as to block the rough plug 550 from falling into the container body. In addition, in the present invention, a friction reducing surface 553a may be formed at corresponding portions of the shrinkage induction grooves 554 on both sides of the hook 553 shown in FIG. .

As another example of the present invention, the present invention, as shown in Figure 15 to 20, protruding obliquely upward to the top edge of the insertion portion 556 of the bottom cap 550, the end extended so that the end is larger than the outer diameter of the insertion portion 556 Form a bar 600.

The stop bar 600 is coupled to the slider 536 naturally by the pusher arm 610 is pushed in the inner diameter direction by the pusher arm 610 while pushing as shown in Fig. Doing,

When the capping is shipped after the user removes the upper cap 534 of the opening member 53 to drink the contents of the container body, the stop bar 600 is restored as the elastic force is opened as shown in Figure 18, which is a slider 536 It prevents reuse by blocking the recombination at the source and contributes to the prevention of safety accidents.
