DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 to 8, reference numeral 3 designates an inner plug of a cap made of a synthetic resin, for example, polyethylene, which is attached to a mouth portion 12 of a container 11. Reference numeral 2 denotes a cylindrical wall, which has a ridge 1 that is pressed against the outer periphery of the mouth portion 12 and that is pressed into engagement with a concave ridge 13 formed in the mouth portion 12. Reference numeral 14 denotes a blocking wall for blocking the passage of the storage items (not shown) in the container 11. Reference numeral 4 denotes a missing portion formed on a part of the cylindrical wall 2, and a downward projection 15 is formed on an upper portion thereof, and a horizontal portion 17 is formed on a distal end portion 16 of the projection 15. On both sides of the projection 15, both ends are bent in a bay shape so that the lower part becomes concave, and reach above the tip part 16 of the downward projection 15, and are continuous with the lacking part 4. 18 are formed.

[0007] Next, reference numeral 10 denotes a thin film formed on the cylindrical wall 2 so as to extend over both the lacking portion 4 and the both end lacking portions 18 and 18 continuous therewith. It is formed. Therefore, when the cap is attached to the mouth portion 12 of the container 11, the thin film 10 closes the outer peripheral surface of the mouth portion 12 together with the lacking portion 4 and the both end lacking portions 18 and 18.

Next, an inner cylinder 19 is provided on the inner side of the cylindrical wall 2 of the inner plug 3 of the cap so as to press against the inner surface of the mouth 12 of the container 11. Reference numeral 20 denotes an upper wall, and the upper wall 20, the cylindrical wall 2,
The inner tube 19 forms a holding portion 21 for pressing and holding the mouth portion 12 from inside and outside. Next, 22 is the barrier 14
The tearing portion 23 is formed inside the tearing groove 22, and a pull-ring-like tearing member 24 is provided above the tearing portion 23. Next, as shown in FIG. 1, a filling cylinder 6 is formed outside the tearing portion 23 of the blocking wall 14, and one side 8 of the filling cylinder 6 corresponding to the lacking portion 4.
However, it is formed in the thin portion 5 which is thinner than the other side 26. The thin portion 5 is formed in the circumferential direction of the injection tube 6 and is easily bent inward. In this configuration, as shown in FIGS. 4 to 8, the inner plug 3 of the cap attached to the mouth portion 12 of the container 11 is pulled out 27 and the inner plug 3 of the cap is removed from the mouth portion 12. In case, bottle opener 2
7, the thin portion 5 is compressed and deformed inward, so that the bottle opener 27 can be applied. Moreover, since the liquid is usually formed to be particularly thin, it is possible to improve the so-called breakage of the liquid droplet when the liquid is poured as a injection cylinder. 31 is the outer lid 7
3 shows a hook portion which is hooked when the shutter is closed.

Next, the opening of the cap using the stopper will be described. First, as shown in FIGS. 4 to 8, the thin portion 5 of the injection tube 6 is pressed inward by the end portion 28 of the stopper 27, and is deformed by being bent inward as shown in FIG. In this case, since the thin portion 5 of the injection tube 6 is formed particularly thin, it is easily bent inward and deformed. For this reason,
As it is, the upper end 3 of the locking portion 29 of the bottle opener 27
Hang 0 on top wall 20. Then, the lower end portion 32 of the locking portion 29 is hung on the distal end portion 16 of the downward projection 15 as shown in FIG. Next, the bottle opener 27 is further rotated in the direction of arrow A27 as shown in FIG. Then, in this case, the bottle opener 27 has the upper end portion 30 as a fulcrum,
Is a point of force, and the lower end portion 32 acts as a lever, so that the cylindrical wall 2 of the cap receives an outward bending force. As shown in FIG. The strip 1 is separated from the concave strip 13 of the container 11 and is moved upward.

Further, in this case, on both sides of the downward projection 15, both ends lacking portions 18 which are bent in a bay shape so that the lower portion becomes concave and extend above the tip portion 16 of the downward projection 15, Due to the presence of the ridge 18, when the ridge 1 passes over the annular protrusion 34 above the concave ridge 13, the diameter of the cylindrical wall 2 is automatically increased easily and with a relatively small force. The protrusion 34 can be moved over.
Further, in this case, the thin film 10 is formed over both the lacking portion 4 and the both end missing portions 18, 18, whereby
Although this portion is useful for closing the mouth portion 12, the thin film 10 is formed as a thin film, so that there is very little resistance to an increase in the diameter of the ridge 1 when passing over the annular protrusion 34. It is. The explanation of this operation is as described above.
The method of pressing and deforming the thin portion 5 by the end portion 28 of the bottle opener 27 has been described, but this is an example,
The thin portion 5 is pressed inward with a hand having no bottle opener 27 in advance and deformed, and in this state, the bottle opener 27 is connected to the upper portion of the upper wall 20 and the tip of the downward projection 15. 16 may be hung, and may be pulled out from the mouth 12 in this manner.

As shown in FIG. 3, the lacking portion 4 of the cylindrical wall 2 and the downward projection 15 therein, the thin portion 5 of the cylindrical wall 2 or the weakening line 9 of the injection cylinder 6 are all provided as shown in FIG. Formed on the opposite side. The outer lid 7 has a main hinge 3 as described later.
5 and the sub-hinge 36 are formed so as to be able to hold the open state and the closed state by themselves, and to maintain the state. Therefore, the outer lid 7 is opened and the contents liquid (not shown) in the container 11 is discharged. When pouring out, it is usually performed with the outer lid 7 facing upward. This is because when the outer lid 7 is in the lower position, the outer lid 7 hinders liquid injection. As described above, when the content liquid is poured with the outer lid 7 facing upward, the liquid to be poured is poured out from the thin portion 5 of the injection tube 6, and the liquid can be more preferably drained due to the thin wall. This also applies to a case where a weakening line 9 described later is formed. That is, the thin portion 5 and the injection tube 6 in which the weakening line 9 is formed usually serve as the injection tube 6 for improving the drainage, and when the cap is removed from the mouth portion 12, it easily breaks or deforms inward. Thus, the stopper 27 can be hung on this cap.

Next, in FIG. 3, a plurality of weakening lines 9 are formed in a thin groove shape in the vertical direction on one side 8 of the injection tube 6 corresponding to the lacking portion 4. Although not shown, the weakening line 9 may be formed when one side 8 of the injection tube 6 is not formed thinner than the other side 26 as described above, or alternatively, as described above. , May be formed when the one side 8 is formed thinner than the other side 26. The weakening line 9 is also provided for allowing the one side 8 to be broken or deformed by being pressed inward by a hand or a bottle opener, so that the bottle opener 27 can be hung. When the inner stopper 3 is removed, the inner stopper 3 is pressed inward by a hand or the stopper 27 to break, compress or deform.

Next, as described above, the distal end portion 16 of the downward projection 15 is formed in the horizontal portion 17. It can be pushed up, so that the force can be evenly applied to the both end notches 18, 18, and the both end notches 18, 18 are each formed in a bay shape so as to have a concave upper portion. By that
Since this portion can be easily spread right and left, the ridge 1 formed on the cylindrical wall 2 smoothly expands the circumferential direction of the cylindrical wall 2 when the ridge 1 over the annular protrusion 34 above the concave ridge 13. Can be performed. Therefore, it is possible to easily get over the annular projection 34. Therefore, it is possible to easily remove the inner plug 3 of the cap from the container 11.

Next, as shown in FIG. 1, the inner plug 3 of the cap has an outer lid 7 integrally with a hinge 37. The hinge 37 is formed by a main hinge 35 at the center and sub hinges 36 provided on both sides thereof. The main hinge 35 is a bent type hinge, and the sub hinge 36 is formed in a substantially sine curve or substantially rectangular wave pulse shape on the side surface, thereby being formed to have elasticity. The hinges 35 and 36 have a self-holding function in the open and closed states of the outer lid 7. When the inner plug 3 thus formed is used by a consumer or the like, the outer lid 7 is opened and the tearing member 23 is pulled upward to tear the groove 2.
The tearing portion 23 is torn off from 2, and a through-hole is formed therein for use. When the contents of the container are consumed and the container 11 is separated into the cap and the container 11 by the collection company, the operation of removing the inner plug 3 of the cap from the container 11 is performed as described above.

[0015]

According to the first and second aspects of the present invention, since the thin portion 5 is formed in the injection tube 6, when the inner plug 3 of the cap is removed from the container by using a bottle opener, this portion is moved inward. The cap 3 is pressed and deformed, whereby the inner plug 3 of the cap can be opened. Thus, it can be easily removed. In addition, when used, the liquid can be effectively drained at the time of pouring, particularly as the thin-walled pouring cylinder 6. According to the third and fourth aspects of the present invention, the weakened line 9 in the vertical direction corresponding to the lacking portion 4 is formed in the injection cylinder 6, so that the portion between the weakened lines 9 is pressed inward. Can be easily broken or deformed, whereby the inner plug 3 of the cap can be opened. Thus, it can be easily removed. The invention according to claim 5 is configured as described above, which is useful for closing the mouth. However, since the thin film 10 is formed in a thin film, the ridge 1 is formed in the recess of the container mouth. The resistance to the increase in diameter when passing over the protrusion at the top can be minimized.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIGS. 1 to 8, reference numeral 3 designates an inner plug of a cap made of a synthetic resin, for example, polyethylene, which is attached to a mouth portion 12 of a container 11. Reference numeral 2 denotes a cylindrical wall, which has a ridge 1 that is pressed against the outer periphery of the mouth portion 12 and that is pressed into engagement with a concave ridge 13 formed in the mouth portion 12. Reference numeral 14 denotes a blocking wall for blocking the passage of the storage items (not shown) in the container 11. Reference numeral 4 denotes a portion for hooking a stopper formed on a part of the cylindrical wall 2, and a downward projection 15 is formed on an upper portion thereof, and a distal end portion 16 of the projection 15 is
7 are formed. And said on both sides of the projections 15, and bend the bay shaped so downward becomes concave, reaching above the front end portion 16 of the downward projections 15, and the corkscrew
Both end lacking portions 18 and 18 are formed to be continuous with the portion 4 for hooking .

[0007] Next, at 10, the stopper is removed from the cylindrical wall 2.
It is a thin film formed so as to extend over both the stopping portion 4 and both end lacking portions 18, 18 continuous with the stopping portion 4, and is formed continuously on the inner surface of the cylindrical wall 2. Therefore, this thin film 10
When the cap is attached to the mouth portion 12 of the container 11, the portion 4 for latching the bottle opener and the portions 18 and 18 lacking both ends also close the outer peripheral surface of the mouth portion 12.

Next, an inner cylinder 19 is provided on the inner side of the cylindrical wall 2 of the inner plug 3 of the cap so as to press against the inner surface of the mouth 12 of the container 11. Reference numeral 20 denotes an upper wall, and the upper wall 20, the cylindrical wall 2,
The inner tube 19 forms a holding portion 21 for pressing and holding the mouth portion 12 from inside and outside. Next, 22 is the barrier 14
The tearing portion 23 is formed inside the tearing groove 22, and a pull-ring-like tearing member 24 is provided above the tearing portion 23. Next, as shown in FIG. 1, a filling cylinder 6 is formed on the outside of the tearing portion 23 of the blocking wall 14, and one side 8 of the filling cylinder 6 corresponding to the part 4 for hooking the bottle opener. However, it is formed in the thin portion 5 which is thinner than the other side 26. The thin portion 5 is formed in the circumferential direction of the injection tube 6 and is easily bent inward. In this configuration, as shown in FIGS. 4 to 8, the inner plug 3 of the cap attached to the mouth portion 12 of the container 11 is pulled out 27 and the inner plug 3 of the cap is removed from the mouth portion 12. In case,
The thinner portion 5 can be compressed and deformed inward by the bottle opener 27, whereby the bottle opener 27 can be applied. Moreover, since the liquid is usually formed to be particularly thin, it is possible to improve the so-called breakage of the liquid droplet when the liquid is poured as a injection cylinder. 31
Indicates a hook portion of the outer lid 7 which is hooked at the time of closing.

Next, the opening of the cap using the stopper will be described. First, as shown in FIGS. 4 to 8, the thin portion 5 of the injection tube 6 is pressed inward by the end portion 28 of the stopper 27, and is deformed by being bent inward as shown in FIG. In this case, since the thin portion 5 of the injection tube 6 is formed particularly thin, it is easily bent inward and deformed. For this reason,
As it is, the upper end 3 of the locking portion 29 of the bottle opener 27
Hang 0 on top wall 20. Then, the lower end portion 32 of the locking portion 29 is hung on the distal end portion 16 of the downward projection 15 as shown in FIG. Next, the bottle opener 27 is further rotated in the direction of arrow A27 as shown in FIG. Then, in this case, the bottle opener 27 has the upper end portion 30 as a fulcrum,
Is a point of force, and the lower end portion 32 acts as a lever, so that the cylindrical wall 2 of the cap receives an outward bending force. As shown in FIG. The strip 1 is separated from the concave strip 13 of the container 11 and is moved upward.

Further, in this case, on both sides of the downward projection 15, both ends lacking portions 18 which are bent in a bay shape so that the lower portion becomes concave and extend above the tip portion 16 of the downward projection 15, Due to the presence of the ridge 18, when the ridge 1 passes over the annular protrusion 34 above the concave ridge 13, the diameter of the cylindrical wall 2 is automatically increased easily and with a relatively small force. The protrusion 34 can be moved over.
Also, in this case, the thin film 10 is formed over both the portion 4 for hooking the bottle opener and the portions 18 and 18 lacking at both ends.
This serves to close the mouth 12 at this portion, but since the thin film 10 is formed as a thin film, there is very little resistance to the increase in diameter when the ridge 1 passes over the annular protrusion 34. You need less. Although the description of this operation has described the method of pressing and deforming the thin portion 5 by the end portion 28 of the bottle opener 27 as described above, this is an example, and this thin portion 5 is It is possible to hang the bottle opener 27 on the upper part of the upper wall 20 and the tip 16 of the downward projection 15 without any problem by pressing the bottle inner side with the hand without the bottle opener 27 to deform it. It may be pulled out from the mouth portion 12 in this manner.

FIG. 3 shows a portion 4 of the cylindrical wall 2 for hooking the bottle opener and a downward projection 15 therein , and a thin portion 5 of the cylindrical wall 2 or a weakening line 9 of a casting cylinder 6 described later. Formed on the opposite side of the outer lid 7. The outer lid 7 is formed by a main hinge 35 and a sub-hinge 36 so as to be able to hold the open state and the closed state by itself as described later so that the state can be maintained. When the content liquid (not shown) in the container 11 is poured out, the outer cover 7 is usually used.
Is performed in a state where is upward. This is because when the outer lid 7 is in the lower position, the outer lid 7 hinders liquid injection.
As described above, when the content liquid is poured with the outer lid 7 facing upward, the liquid to be poured is poured out from the thin portion 5 of the injection tube 6, and the liquid can be more preferably drained due to the thin wall. This also applies to a case where a weakening line 9 described later is formed. That is, the thin portion 5 and the injection tube 6 in which the weakening line 9 is formed usually serve as the injection tube 6 for improving the drainage, and when the cap is removed from the mouth portion 12, it easily breaks or deforms inward. Thus, the stopper 27 can be hung on this cap.

Next, FIG. 3 shows the injection cylinder 6,
A plurality of weakening lines 9 are formed in the vertical direction on one side 8 corresponding to the portion 4 for locking the bottle opener in a thin groove shape. Although not shown, the weakening line 9 may be formed when one side 8 of the injection tube 6 is not formed thinner than the other side 26 as described above, or alternatively, as described above. , May be formed when the one side 8 is formed thinner than the other side 26. And this weakening line 9
The one side 8 is also pressed inward by a hand or a bottle opener to be broken or deformed so that the bottle opener 27 can be hung.
At the time of removal, it is pressed inward by a hand or a bottle opener 27 to break, compress or deform.

Next, as described above, the distal end portion 16 of the downward projection 15 is formed in the horizontal portion 17. It can be pushed up, so that the force can be evenly applied to the both end notches 18, 18, and the both end notches 18, 18 are each formed in a bay shape so as to have a concave upper portion. By that
Since this portion can be easily spread right and left, the ridge 1 formed on the cylindrical wall 2 smoothly expands the circumferential direction of the cylindrical wall 2 when the ridge 1 over the annular protrusion 34 above the concave ridge 13. Can be performed. Therefore, it is possible to easily get over the annular projection 34. Therefore, it is possible to easily remove the inner plug 3 of the cap from the container 11.

Next, as shown in FIG. 1, the inner plug 3 of the cap has an outer lid 7 integrally with a hinge 37. The hinge 37 is formed by a main hinge 35 at the center and sub hinges 36 provided on both sides thereof. The main hinge 35 is a bent type hinge, and the sub hinge 36 is formed in a substantially sine curve or substantially rectangular wave pulse shape on the side surface, thereby being formed to have elasticity. The hinges 35 and 36 have a self-holding function in the open and closed states of the outer lid 7. When the inner plug 3 thus formed is used by a consumer or the like, the outer lid 7 is opened and the tearing member 23 is pulled upward to tear the groove 2.
The tearing portion 23 is torn off from 2, and a through-hole is formed therein for use. When the contents of the container are consumed and the container 11 is separated into the cap and the container 11 by the collection company, the operation of removing the inner plug 3 of the cap from the container 11 is performed as described above.

[0015]

According to the first and second aspects of the present invention, since the thin portion 5 is formed in the injection tube 6, when the inner plug 3 of the cap is removed from the container by using a bottle opener, this portion is moved inward. The cap 3 is pressed and deformed, whereby the inner plug 3 of the cap can be opened. Thus, it can be easily removed. In addition, when used, the liquid can be effectively drained at the time of pouring, particularly as the thin-walled pouring cylinder 6. According to the third and fourth aspects of the present invention, a vertical weakening line 9 is formed in the injection cylinder 6 corresponding to the portion 4 for hooking the stopper .
Since the portion between the weakening lines 9 can be easily broken or deformed by pressing inward, the inner plug 3 of the cap can be opened.
Thus, it can be easily removed. The invention according to claim 5 is configured as described above, which is useful for closing the mouth. However, since the thin film 10 is formed in a thin film, the ridge 1 is formed in the recess of the container mouth. The resistance to the increase in diameter when passing over the protrusion at the top can be minimized.
