Thus, the mouth portion 6a of the outer cylinder 6 is clamped from inside and outside. An anti-slip knurl 8f is formed on the outer peripheral surface of the body portion 8b, and an arrow 8g is provided on the top surface of the top portion 8a so as to indicate the opening direction.
[0042]
The bottom cover 3 includes a pressing portion 3a having a convex upper surface and a concave surface on the lower surface, a peripheral wall portion 3c having a J-shaped cross section with a peripheral edge of the pressing portion 3a, and a concave surface of the pressing portion 3a. A protrusion 3d protruding downward from the center of the lower surface is integrally molded. A female screw 3e with a small number of threads is formed in the annular groove 3b, that is, on the inner peripheral surface of the peripheral wall 3c. The female screw 3e and the male screw 9a at the lower end of the inner cylinder 9 are screwed together. The bottom lid 3 is fitted to the lower end of the inner cylinder 9 filled with the pressure gas and the raw material 11 by fitting the lower end of the inner cylinder 9 into the annular groove 3b and pushing the pushing part 3a into the inner cylinder 9. Is hermetically and liquid tightly sealed. Moreover, the rectangular recessed part 3f for the rotation prevention with respect to the outer cylinder 6 is provided in the peripheral wall part 3c in one place or two places which oppose. The bottom lid 3 is prevented from rotating with respect to the outer cylinder 6 by fitting the recess 3 f with the convex part 7 of the outer cylinder 6 so as to be detachable.
[0043]
In addition, the recessed part and convex part for rotation prevention of the bottom cover 3 are good also considering the outer cylinder 6 side as a recessed part, and making the bottom cover 3 side a convex part.
[0044]
The raw material 11 to be filled in the inner cylinder 9 includes green tea, coffee, black tea, concentrated minerals, deep sea water extracted minerals, health foods, drugs, concentrated fruit juices, dairy products, alcohol, concentrated vegetables, soup ingredients, vitamins, sugars , Herbs, fermenting bacteria, etc. in powder, granule, tablet or liquid. Moreover, as the pressure gas, an inert gas that can safely maintain the quality of the raw material 11 is good, and examples thereof include nitrogen, helium, argon, carbon dioxide, nitrous oxide, or a mixed gas thereof.
[0045]
The bottom lid 3 is connected to the outer cylinder 6 by a flexible connecting piece 12. The upper end of the connecting piece 12 is fixed to the outer peripheral surface of the outer cylinder 6, and the lower end is fixed to the lower surface of the bottom cover 3. When the bottom cover 3 is removed from the inner cylinder 9, the connecting piece 12 is in a substantially straight state. And the bottom cover 3 is suspended from the outer cylinder 6. The bottom cover 3 can be resin-molded integrally with the outer cylinder 6 (parent cap 1) together with the connecting piece 12.
[0046]
In the bottle cap of the first embodiment, the parent cap 1, the child cap 2 and the bottom lid 3 are assembled as shown in FIG. 3, and the inner cylinder 9 is filled with the raw material 11 together with a pressure gas such as an inert gas. Then, the bottom cover 3 is sealed, and the mouth portion 6a of the outer cylinder 6 is sealed with the cap body 8 of the child cap 2, and the bottom cover 3 has its concave portion 3f connected to the convex portion 7 of the outer cylinder 6. It is made to fit and it is set as a rotation prevention state with respect to the outer cylinder 6. FIG. And when attaching the bottle cap assembled in this way to the mouth part 50a of the bottle 50 such as a plastic bottle as shown in FIG. 4, the outer cylinder 6 is inserted into the bottle mouth part 50a, and the parent cap 1 The bottle mouth part 50a is sealed with the cap body 5 by screwing the female screw 5c of the cap body 5 into the male screw of the bottle mouth part 50a and tightening it tightly.
[0047]
The bottle cap thus attached to the bottle 50 is filled with the pressure gas in the inner cylinder 9, so that intrusion of oxygen and moisture into the inner cylinder 9 can be prevented by the internal pressure, and the bottom lid 3 Since the lower end portion of the inner cylinder 9 is fitted in the annular groove 3b and screwed to the inner cylinder 9, even if the inner pressure of the pressure gas is applied to the bottom lid 3, the pressure gas from the inner cylinder 9 is applied. Can be reliably prevented.
[0048]
Between the outer cylinder 6 and the inner cylinder 9, the step 6c on the inner peripheral surface of the outer cylinder 6 and the step 9c on the outer peripheral surface of the inner cylinder 6 are close to each other and face each other. It is possible to prevent the liquid inside from penetrating and rising between the inner peripheral surface of the outer cylinder 6 and the outer peripheral surface of the inner cylinder 9.
[0049]
Between the mouth 6a of the outer cylinder 6 and the child cap 2, the sealing ring 10 of the child cap 2 is press-fitted into the outer cylinder 6 and the top 8a of the child cap 2 is the upper end of the outer cylinder 6 as described above. Since the sealing ring 10 clamps the mouth portion 6a of the outer cylinder 6 from the inside and outside with the corner portion of the body portion 8b, the air tightness and liquid tightness of the child cap 2 with respect to the mouth portion 6a of the outer cylinder 6 are extremely high. Very expensive.
[0050]
An operation associated with opening the child cap 2 in the mounting state shown in FIG. 4 will be described with reference to FIG.
When a finger is put on the trunk portion 8b of the child cap 2 and rotated in the direction of the arrow from the state shown in FIG. 9A, the annular lower peripheral edge portion 8c of the trunk portion 8b becomes unrotatable with respect to the mouth portion 6a of the outer cylinder 6. Therefore, as shown in FIG. 5B, it is separated vertically at the notch 8d and the lower peripheral edge portion 8c remains as it is, while the upper body portion 8b is rotated by screwing with the mouth portion 6a. While rising. Along with this, the inner cylinder 9 also rises while rotating, but the bottom cover 3 is prevented from rotating with respect to the outer cylinder 6 and therefore does not rotate following the inner cylinder 9 and the child cap 2 is further rotated to rotate the inner cylinder. When 9 is further raised, the male screw 9 a at the lower end of the inner cylinder 9 and the female screw 3 e of the bottom cover 3 are unscrewed, and the bottom cover 3 is released from the lower end of the inner cylinder 9.
[0051]
It should be noted that even if a force (twist) is applied to the child cap 2 so that the body portion 8b of the child cap 2 is vertically separated at the notch 8d, the parent cap 1 is firmly fixed so as not to rotate with respect to the mouth portion 50a of the bottle 50. It is tightened.
[0052]
The bottom lid 3 released from the lower end of the inner cylinder 9 is pushed down by the pressure gas filled in the inner cylinder 9 as shown in FIG. The bottom lid 3 is released from the outer cylinder 6 and falls off when the fitting with the convex portion 7 at the lower end is released. As a result, as shown in FIG. 4D, the raw material 11 in the inner cylinder 9 is jetted into the bottle 50 together with the pressure gas, and mixed with the liquid in the bottle 50. The dropped bottom lid 3 is suspended from the outer cylinder 6 when the connecting piece 12 is restored to a substantially straight state.
[0053]
To drink the liquid in the bottle 50, the child cap 2 is removed from the mouth 6a of the outer cylinder 6, the inner cylinder 9 is extracted from the outer cylinder 6, and the mouth 6a is opened. At that time, if necessary, the child cap 2 is closed again with respect to the mouth portion 6a of the outer cylinder 6 and the bottle 50 itself is shaken. After the raw material 11 is well mixed with the liquid, the child cap 2 is removed.
[0054]
It can be confirmed that the bottom lid 3 is dropped by separating the body portion 8b of the child cap 2 vertically at the cut 8d. However, when the bottle 50 can be seen through, the bottom lid 3 It can be visually confirmed that it has dropped out.
[0055]
If the parent cap 1 is removed from the bottle 50, the bottom lid 3 can be taken out together with this in the suspended state, so that the recyclability of the bottle 50 is good.
[0056]
By providing a notch 8d in the body portion 8b of the child cap 2 and making the annular lower peripheral edge portion 8c non-rotatable with respect to the mouth portion 6a of the outer cylinder 6, it is possible to prevent the child cap 2 from being loosened, If the child cap 2 is not forcibly turned until it is separated by the notch 8d, it will be confirmed that the bottom lid 3 is dropped and the raw material 11 cannot be ejected, but such a structure is not necessarily required.
[0057]
6 to 8 show a bottle cap according to a second embodiment of the present invention. FIG. 6 shows an assembled state, FIG. 7 shows a state in which the bottle is set, and FIG. 8 shows an opening state. 3, and correspond to FIG. 4 and FIG. In the first embodiment, the connecting piece 12 for connecting the bottom lid 3 to the outer cylinder 6 to be suspended is provided. However, in the second embodiment, this is omitted, and the rest is the first embodiment. Same as example.
[0058]
Therefore, in the second embodiment, the bottom lid 3 settles in the liquid in the bottle 50 without being suspended from the outer cylinder 6. 9A shows the state in which the raw material 11 is ejected by turning the child cap 2 in the opening direction, and the bottom cover 3 sinks. FIG. 9B shows the state in which the child cap 2 is closed again. (C) shows the state which is mixing the raw material 11 by shaking the bottle 50, respectively. Since the bottom lid 3 has the projection 3d, the projection 3d is given directionality when it settles in the liquid in the bottle 50.
[0059]
10 to 13 show a bottle cap according to a third embodiment of the present invention, FIG. 10 is a sectional view up to assembly, FIG. 11 is a perspective view of a bottom cover, FIG. 12 is a perspective view of a detent member, and FIG. It is sectional drawing of the operation state which opens. As shown in FIG. 10A, the bottle cap according to the third embodiment includes a rotation stopper member 4 in addition to the parent cap 1, the child cap 2, and the bottom lid 3.
[0060]
The parent cap 1 in the third embodiment is provided with a recess 7a at the lower end of the outer cylinder 6 in place of the rotation-preventing projection 7 in the first embodiment. Is the same. Further, the child cap 2 in the third embodiment is formed with a female screw 9d at the lower end of the inner peripheral surface of the inner cylinder 9 in place of the male screw 9a provided at the lower end of the outer peripheral surface of the inner cylinder 9 in the first embodiment. However, the rest is the same as the child cap of the first embodiment.
[0061]
The bottom cover 3 in the third embodiment is significantly different from that in the first embodiment, and is composed of a pushing portion 13a and a flange portion 13b as shown in FIG. 11, and on the outer periphery of the pushing portion 13a, A male screw 13c screwed with the female screw 9d is formed, an annular groove 13d is formed on the outer periphery of the flange portion 13b, and a cross-shaped groove 13e having a trapezoidal cross section is formed on the lower surface of the flange portion 13b.
[0062]
The bottom lid 3 seals the lower end opening of the inner cylinder 9 in an airtight and liquid-tight manner when the male screw 13 c is screwed into the female thread 9 d of the inner cylinder 9 and the pushing portion 13 a is pushed into the inner cylinder 9. In the screwing operation at that time, the bottom lid 3 can be rotated using the cross-shaped groove 13e. Since the outer diameter of the flange 13b of the bottom cover 3 is substantially equal to the outer diameter of the lower end of the inner cylinder 9, the inner cylinder 9 can be inserted into the outer cylinder 6 while being sealed with the bottom cover 3, and FIG. As shown in FIG. 3, when the inner cap 9 is inserted into the outer tube 6 to the maximum by covering the child cap 2 over the mouth 6 a of the outer tube 6, the bottom cover 3 comes out of the lower end opening of the outer tube 6.
[0063]
As shown in FIG. 12, the anti-rotation member 4 added in the third embodiment is integrally provided with a cross-shaped trapezoidal cross-shaped rib 14b on the inner side of the ring portion 14a and an annular protrusion on the inner peripheral surface of the ring portion 14a. The part 14c is formed, and the rectangular convex part 14d for rotation prevention is integrally protrudingly provided from the two places which the ring part 14a opposes. The detent member 4 is connected to the outer cylinder 6 by a flexible connecting piece 12. The upper end of the connecting piece 12 is fixed to the outer peripheral surface of the outer cylinder 6, and the lower end is fixed to the ring portion 14a of the anti-rotation member 4. When the connecting piece 12 is restored to a substantially straight state, the anti-rotation member 4 is removed. The cylinder 6 is suspended. The anti-rotation member 4 can be resin-molded integrally with the outer cylinder 6 (parent cap 1) together with the connecting piece 12.
[0064]
The anti-rotation member 4 is formed by combining the parent cap 1, the child cap 2 and the bottom lid 3 as shown in FIG. 10 (B), and then pressing it toward the bottom lid 3 as shown in FIG. The cross-shaped rib 14b having the trapezoidal cross section of the stopper member 4 is forcibly fitted into the cross-shaped groove 13e having the trapezoidal cross section of the bottom cover 3, and the annular protrusion 14 on the inner periphery of the rotation preventing member 4 is The annular groove 13d is forcibly fitted, and the convex portion 14d of the rotation preventing member 4 is detachably fitted to the concave portion 7a at the lower end of the outer cylinder 6.
[0065]
As a result, the anti-rotation member 4 and the bottom lid 3 are combined so as not to be separated from each other, and the anti-rotation member 4 holds the bottom lid 3 and is in a non-rotating state with respect to the outer cylinder 6.
[0066]
In the case of the bottle cap of the third embodiment, as shown in FIG. 13 (A), when the child cap 2 is turned in the direction of the arrow, the inner cylinder 9 is also rotated, leaving the annular lower peripheral edge portion 8c of the trunk portion 8b. However, the bottom cover 3 is prevented from rotating with respect to the outer cylinder 6 by the anti-rotation member 4, and therefore does not rotate following the inner cylinder 9. The child cap 2 is further rotated to further rotate the inner cylinder 9. When raised, the female screw 9d at the lower end of the inner cylinder 9 and the male screw 13c of the bottom cover 3 are unscrewed as shown in FIG. 5B, and the bottom cover 3 is released from the lower end of the inner cylinder 9. The
[0067]
The bottom lid 3 released from the lower end of the inner cylinder 9 is pushed down by the pressure gas filled in the inner cylinder 9, and the rotation preventing member 4 is also pushed down together with this, so that the convex portion 14d becomes the outer cylinder. 6 is disengaged from the recess 7 a at the lower end of 6, and the rotation preventing member 4 is released from the outer cylinder 6 and falls off while holding the bottom cover 3. As a result, as shown in FIG. 5C, the raw material 11 in the inner cylinder 9 is ejected at a stretch together with the pressure gas. The fall-off preventing member 4 that has fallen is suspended from the outer cylinder 6 while holding the bottom cover 3 by restoring the connecting piece 12 to a substantially straight state.
[0068]
In the case of the bottle cap of the third embodiment, the anti-rotation member 4 is required, but the assembly is performed after filling the inner cylinder 9 of the child cap 2 with the raw material 11 and the pressure gas and sealing with the bottom lid 3. The sealed inner cylinder 9 is inserted into the outer cylinder 6 as it is, the child cap 2 is put on the mouth portion 6a of the outer cylinder 6, and the rotation preventing member 4 is pressed toward the bottom cover 3 to complete the process.
