On the circumferential surface, each of the stop teeth 42 has a triangular shape, one of which is a beveled edge 43 and the other of which is a vertical side 44, as shown in Fig. 2(D).

The opening device 48 of the bottom cover B includes: a stopper portion 41 formed on the skirt portion 4 of the bottom cover B, and a blocking portion 86 formed at an end portion of the lower end circumferential edge of the adapter body C, It is used to prevent the rotation of the stopper portion 41 when the bottom cover B is opened.

The aptamer C has an integrally formed skirt portion 6, an opening portion 7, and an fitting portion 8, and the threaded portion 60 formed on the inner circumferential surface of the skirt portion 6 is formed with the threaded portion 90 on the outer circumferential surface of the opening portion 9 of the container D. Engaging, the aptamer C is connected to the opening 9 of the container D, thereby The aptamer C can be attached to the opening portion 9 of the container D, and the lid body A is attached to the opening portion 7 of the adapter body C, thereby closing the opening portion 9 of the container D.

The opening portion 7 of the aptamer C and the fitting portion 8 are integrally formed with the skirt portion 6, and extend in the axial direction into a tubular shape in which both ends are open to allow the lumen portion 3 to be inserted, and the lumen of the lid body A The portion 3 is inserted into the opening portion 7 of the aptamer C and the fitting portion 8, and is exposed to a predetermined length from the lower end of the i-shaped fitting portion 8, and the inner surface of the opening portion 7 of the compounding body C and the cavity of the lid body A The outer surface of the tube portion 3 forms a sealing contact at least in part of the axial length, and the threaded portion 70 formed on the outer circumferential surface of the opening portion 7 of the adapter body C and the inner circumferential surface of the skirt portion 1 formed on the lid body A The upper threaded portion 10 is engaged, and the aptamer C is joined to the cover A. Moreover, the thin slit 61 is formed along the entire circumference of the lower circumferential edge portion of the skirt portion 6, so that the snap ring 62 is formed at the lower circumferential edge portion of the skirt portion 6, so that the portion of the skirt portion 6 on the upper side of the slit 61 can be forced. Separation from the collar 62 of the skirt 6 on the underside of the slit 61 occurs. The anti-slip knurl 63 is formed on the outer circumferential surface of the skirt portion 6 above the slit 61.

The fitting portion 8 of the aptamer C is composed of a sealing portion 80, an elastic portion 83, and a blocking portion 86. The sealing portion 80 serves to seal when the accommodating body C closes the opening portion 9 of the container D, and the sealing portion 80 includes a sealing flange 81 which is a radially extending portion of the circumferential outer wall of the upper end of the fitting portion 8. And the end thereof is progressively contracted to guide the insertion of the adapter C into the opening portion 9 of the container D; the elastic portion 83 serves to keep the blocking portion 86 of the opening device 48 of the bottom cover B close to the stopper portion 41. With the cooperation, the elastic portion 83 is composed of a plurality of elastic strips 84 which together form a trans-helical space structure, and has elasticity in the axial direction; the blocking portion 86 is used to block the stopper portion 41 when the bottom cover B is opened. Rotating, the blocking portion 86 may extend substantially in the axial direction of the lower end of the fitting portion 8 of the aptaming body C, and is formed by a plurality of blocking teeth 87 formed on the circumferential edge of the lower end of the fitting portion 8, the blocking teeth 87. Formed by a plurality of reverse serrations along the unsealing direction, each of the blocking teeth 87 has a triangular shape, one of which is a beveled edge 88 and the other is a vertical side 89, as shown in Fig. 2 (A), 2 (B), 2 (C)The blocking teeth 87 of the aptamer C are engaged with the stopper teeth 42 of the bottom cover B at the time of unsealing to block the bottom cover B from rotating in the unsealing direction with the cover A.

The dispensing cover having the structure of the first embodiment is assembled in the following manner.

As shown in FIG. 3, the lumen portion 3 of the lid body A is inserted into the opening portion 7 of the adapter body C and The mating set of threads is partially engaged, and the raw material E is supplied together with the pressurized gas from the opening portion 30 of the inverted upwardly facing tube portion 3 into the lumen portion 3 of the cap body A.

As shown in Fig. 4, the bottom cover B is placed on the opening portion 30 of the lumen portion 3, at which time the elastic portion 83 of the adapter C is moderately compressed in the axial direction, so that the stopper teeth 42 of the bottom cover B are closed. Cooperating closely with the blocking teeth 87 of the aptamer C, and then rotating the bottom cover B together with the accommodating body C in the sealing direction until the bottom cover B is screwed with the set of threads of the opening portion 30 of the cavity portion 3, At this time, the annular recessed portion 51 of the bottom cover B and the opening portion 30 of the cavity portion 3 of the cover A are forcibly engaged with each other by the cooperation of a set of threads, so that the convex portion of the seal ring 52 is received by the lumen The opening 30 of the portion 3 is compressed. Therefore, the opening portion 30 of the lumen portion 3 has a high sealing property by the closing of the bottom cover B, and even if the pressurized gas is encapsulated in the lumen portion 3, the liquid tightness and the airtightness are sufficiently ensured; The aptamer C is rotated separately in the sealing direction so that the set of threads that match the aptamer C and the cover A are advanced and tightened to each other until the snap ring 12 of the skirt 1 passes the outer circumferential surface of the opening 7 of the compliant body C. The annular projection 71 causes the snap ring 12 to be engaged and locked by the annular projection 71; at this time, the interaction force between the stop tooth 42 of the bottom cover B and the blocking tooth 87 of the adapter C generates a sealing direction. Due to the axial elastic contraction of the elastic portion 83, the oblique side 43 of the stopping tooth 42 and the oblique side 88 of the blocking tooth 87 are allowed to slide in the sealing direction, thereby ensuring the opening of the bottom cover B and the cavity portion 3 during assembly. 30 combined sealing performance.

After the opening portion 30 of the lumen portion 3 is closed in the above manner by the bottom cover B, the stopper teeth 42 of the bottom cover B are tightly engaged with the blocking teeth 87 of the matching body C due to the axial elastic action of the elastic portion 83. .

The compliant aptamer C assembled in the above manner and the lumen portion 3 of the lid A are inserted into the opening 9 of the container D together with the bottom cover B, and the accommodating body C is rotated in the sealing direction, and the lumen portion 3 follows the bottom. The lid B is inserted into the opening portion 9 of the container D until the adapter C seals the opening portion 9 of the container D as shown in FIG.

When the aptamer C is rotated in the sealing direction, the threaded portion 60 of the skirt 6 begins to engage the threaded portion 90 of the opening 9 of the container D, and then the threaded portion 60 and the threaded portion 90 are tightened until the skirt 6 The snap ring 62 passes through the annular projection 91 on the outer circumferential surface of the opening portion 9 of the container D, so that the card 62 is engaged by the annular projection 91 and locked, and This locking state is also maintained when the cover A is unsealed, as shown in Figures 6(A) and 6(B).

The opening portion 9 of the container D is sealed in the above state.

It should be noted that the dispensing cover assembled in the above state, because of the elastic action of the elastic portion 83 of the aptamer C, causes a set of threads of the cover A and the matching body C, and the cover A and the bottom cover B While the mating set of threads are intimately engaged, respectively, the stop teeth 42 of the bottom cover B remain in intimate engagement with the blocking teeth 87 of the aptamer C.

It should also be noted that the dispensing cover assembled in the above state, because of the elastic action of the elastic portion 83 of the accommodating body C, allows the retaining teeth 42 of the bottom cover B to be in close mesh with the blocking teeth 87 of the compliant body C while The cover body A is allowed to have a certain range of rotational malfunction, and the sealing performance of the bottom cover B in combination with the opening portion 30 of the cavity portion 3 can be ensured.

When the cover A generates a malfunction in the sealing direction, an interaction force in the sealing direction is generated between the stopper teeth 42 of the bottom cover B and the blocking teeth 87 of the adapter C, because the elastic portion 83 generates an axial direction. The elastic contraction allows the oblique side 43 of the stopper tooth 42 and the oblique side 88 of the blocking tooth 87 to relatively slide in the sealing direction, thereby ensuring the sealing performance of the bottom cover B in combination with the opening portion 30 of the lumen portion 3.

When the cover A generates a malfunction in the unsealing direction but does not cause the skirt 1 of the cover A to be separated at the slit 11, the elastic portion 83 of the adapter C allows the barrier 86 to have a certain range in the unsealing direction. Rotation, at this time, a force in the unsealing direction is not generated between the blocking teeth 87 and the stopper teeth 42, thereby ensuring the sealing performance of the bottom cover B in combination with the opening portion 30 of the cavity portion 3.

The dispensing cover having the structure of the first embodiment is unsealed in the following manner.

If the cover A is rotated in the unsealing direction, and the accommodating body C is in the state of being sealed and locked as described above with the opening portion 9 of the container D, then the skirt 1 of the cover A is opposed to the upper side of the slit 11 The portion can be moved upward, and since the snap ring 12 is kept engaged with the annular projection 71, the snap ring 12 under the slit 11 cannot move upward. Therefore, the snap ring 12 is separated from the upper side portion of the skirt 1 at the slit 11, and is held at this position.

Therefore, since the cover A cannot be rotated, the sealing state of the cover A can be maintained unless a sufficiently large force for forcibly causing such separation is applied to the cover A. On the other hand, in the opening portion 9 of the container D, when the lid body A is rotated together with the tube portion 3 and the bottom cover B in the unsealing direction, the snap ring 12 is forced at the slit 11 and the upper portion of the skirt portion 1 Separately, as shown in Figure 7. Then, the cover body A and the cavity portion 3 continue to rotate in the unsealing direction. At this time, since the outer surface of the cavity portion 3 of the cover A radially supports the plurality of elastic strips 84 of the elastic portion 83, the elasticity is ensured. The plurality of elastic strips 84 of the portion 83 are not deformed, and the stop teeth 42 of the opening device 48 of the bottom cover B engage with the blocking teeth 87 and an unsealing action occurs. The bottom cover B cannot be rotated with the lumen portion 3, and therefore, the threaded portion 40 of the bottom cover B retreats from the engaged state of the threaded portion 31 of the further rotating and upwardly moving lumen portion 3, and then separates, so that the bottom cover B is from the cavity The tube portion 3 is detached as shown in FIG. When the bottom cover B is detached, the raw material E in the cavity portion 3 is suddenly ejected together with the pressurized gas, and the bottom cover B falls into the container D.

Since the outer diameter of the detached bottom cover B is larger than the inner diameter of the opening portion 7 of the aptamer C, it does not pass through the opening portion 7 of the accommodating body C to the outside of the container D.

It should be noted that when the cover body A is rotated together with the lumen portion 3 and the bottom cover B in the unsealing direction, since the outer surface of the lumen portion 3 of the cover A radially supports the plurality of elastic strips 84 of the elastic portion 83 Therefore, it is ensured that the plurality of elastic strips 84 of the elastic portion 83 are not deformed, and the stopping teeth 42 of the opening device 48 of the bottom cover B are engaged with the blocking teeth 87 and the unsealing action occurs, so that the falling of the bottom cover B can certainly be realized. .

It should also be noted that after the lid body A is unsealed and removed, the aptamer C remains on the opening portion 9 of the container D, and then the container D is inverted so that the opening portion 9 of the container D is downward, at this time the container D The contents can flow out through a plurality of gaps 85 of the aptamer C.
