- the holding section 112 has a configuration in which a rib 112 a is formed to protrude inward in the holding section 112 , and the rib 112 a enters a depressed section 33 of the bottle 30 so that the holding section 112 firmly holds the upper end section 32 of the bottle 30 and is not removed from the mouth 31 of the bottle 30 .
- the lid body 12 included in the inner stopper 10 includes a lid section 121 and a junction section 122 .
- the lid section 121 is a portion which spreads in a plate shape and above the hollow section 111 such that the lid section 121 covers the hollow section 111 .
- the junction section 122 is junctioned circumferentially to an upper end edge 111 b of the hollow section 111 , and closes an opening on an upper end of the hollow section 111 together with the lid section 121 .
- the main body 11 and the lid body 12 which are included in the inner stopper 10 are integrally formed as a single component, and however, the junction section 122 is easily broken when the lid section 121 is pressed from above, and when the junction section 122 is broken, the lid body 12 becomes a part separate from the main body 11 . This point will be described later.
- a recess 121 a is formed on an upper surface of the lid section 121 so that the lid section 121 is made to have a shape of being away from an upper surface of the cap 20 , and even if a force is applied to the upper surface of the cap 20 and the upper surface is depressed, the force is not applied to the lid section 121 .
- the cap 20 included in the cap assembly 1 A of the comparative example includes a shell section 21 , a receiving section 22 and a protrusion section 23 .
- the shell section 21 is a portion which is formed to be hollow while opening downward, and is put over the mouth 31 of the bottle 30 upon the inner stopper 10 while covering the inner stopper 10 .
- a female screw thread 211 which is screwed to a male screw thread 34 provided in the bottle 30 is formed on an inner circumference surface of the shell section 21 , and the cap 20 is rotated to be attached or removed.
- the receiving section 22 is a portion which protrudes downward from an inner side upper surface of the shell section 22 , has a lower opening section, and receives the lid section 121 of the main body 11 in an inside thereof to surround an edge 121 b of the lid section 121 .
- the protrusion section 23 is a portion which has a shape of rib protruding inward from an inner circumference surface of the receiving section 22 . As described later, the protrusion section 23 protrudes up to a position where the protrusion section 23 interferes with the edge 121 b of the lid section 121 .
- the cap assembly 1 A having the configuration illustrated in this FIG. 1 In order to attach the cap assembly 1 A having the configuration illustrated in this FIG. 1 to the bottle 30 , after the bottle 30 is filled with a content, the upper end section 32 of the bottle 30 is held between a lower end section of the hollow section 11 of the inner stopper 10 and the holding section 112 . In other words, the inner stopper 10 is capped to the bottle 30 . After this capping, the cap 20 is put thereover and rotated, and the cap 20 is attached such that the protrusion section 23 of the cap 20 comes to a position immediately above the lid section 121 of the inner stopper 20 , as illustrated in FIG. 1 . Then, shrink wrap packaging and the like are performed, and the cap 20 becomes a state in which the cap 20 is not rotated inadvertently from the position illustrated in this FIG. 1 .
- FIG. 2 to FIG. 4 are views illustrating behaviors at the time of opening by a consumer as to the comparative example illustrated in FIG. 1
- the consumer rotates the cap in a direction of closing further. Then, the cap 20 moves in a direction indicated by arrow A illustrated in FIG. 2 , and the lid section 121 moves and comes upper than the protrusion section 23 while the edge 121 b of the lid section 121 of the inner stopper 10 interferes with the protrusion section 23 of the cap 20 to expand the receiving section 22 elastically, as illustrated in FIG. 2 .
- the cap 20 When the cap 20 is further rotated in the direction of closing so that the cap 20 is further moved in the direction of arrow A, the cap 20 presses the lid section 121 , and the junction section 122 is broken, as illustrated in FIG. 3 .
- the cap 20 When the cap 20 is rotated in the direction of closing and becomes the state illustrated in FIG. 3 , the cap 20 becomes not further rotating in the direction of closing, and then, the cap 20 is now rotated in a direction of opening. Then, as illustrated in FIG. 4 , the lid section 12 is removed from the bottle 30 together with the cap 20 while only the lid section 12 of the inner stopper 10 is separated from the main body 11 and remains entering the receiving section 22 of the cap 20 . Since the protrusion section 23 is formed in the cap 20 , the lid section 20 thereafter remains entering the receiving section 22 of the cap 20 .
- FIG. 5 is a view illustrating torque changes when the cap 20 is rotated temporarily in a direction of closing in order to open the cap 20 initially in the comparative example illustrated in FIG. 1 to FIG. 4 .
- the cap 20 When the cap is further rotated in the direction of closing, the cap 20 now presses the lid section 121 , and when the cap 20 is furthermore rotated in the direction of closing, the junction section 122 is broken while the torque is increasing (region c). Then, the cap 20 becomes not rotating in the direction of closing, and then, the cap 20 is now rotated in the direction of opening, so that the cap 20 is removed.
- FIG. 6 is a vertical sectional view of a cap assembly of a first embodiment according to the present invention.
- a cap assembly 1 B of the first embodiment includes an inner stopper 40 and a cap 50 .
- the inner stopper 40 is a component which is put over a mouth 61 of a bottle 60 to close the mouth 61 (see FIG. 14 ).
- the cap 50 is a component which is put over the mouth 61 of the bottle 60 upon the inner stopper 40 such that the cap 50 covers the inner stopper 40 .
- the inner stopper 40 includes a main body 41 and a lid body 42 .
- the main body 41 includes a hollow section 411 and a holding section 412 .
- the hollow section 411 has a hollow shape which has an upper opening and a lower opening and communicates with the mouth 61 of the bottle 60 , and at the time of capping, a lower end section 411 a thereof is inserted to the mouth 61 of the bottle 60 (see FIG. 15 ).
- a male screw thread 411 c which circles helically on an outer circumference surface of the hollow section 411 and is screwed to a female screw thread 541 of the cap 50 is formed on the outer circumference surface in the hollow section 411 .
- the holding section 412 included in the main body 41 plays a role of receiving an insertion of an upper end section 62 of the bottle 60 to hold the upper end section 62 of the bottle 60 in cooperation with the lower end section 411 of the hollow section 411 which lower end section 411 a is inserted to the mouth of the bottle 60 .
- the holding section 412 has a configuration in which a rib 412 a is formed in the holding section 412 , and the rib 412 a enters a depressed section 63 (see FIG. 14 ) of the bottle 60 so that the holding section 412 firmly holds the upper end section 62 of the bottle 60 and is not removed from the mouth 61 of the bottle 60 .
- the lid body 42 included in the inner stopper 40 includes a lid section 421 and a junction section 422 .
- the lid section 421 is a portion which spreads in a plate shape above the hollow section 411 such that the lid section 421 covers the hollow section 411 .
- the junction section 422 is junctioned circumferentially to an upper end edge 411 b of the hollow section 411 , and closes an opening on an upper end of the hollow section 411 together with the lid section 421 .
- the main body 41 and the lid body 42 which are included in the hollow section 40 are integrally formed as a single component, and however, the junction section 422 is considerably easily broken when the lid section 421 is pressed from above. When the junction section 422 is broken, the lid body 42 becomes a part separate from the main body 41 .
- a recess 421 a is formed on an upper surface of the lid section 421 so that the lid section 421 is made to be away as much as possible from an upper surface of the cap 50 , and thus, even if a force is applied to the upper surface of the cap 50 and the upper surface is depressed, the force is not applied to the lid section 421 .
- the cap 50 includes a shell section 51 , a receiving section 52 , a protrusion section 53 , a screwing section 54 which are illustrated in FIG. 6 , and further, hooks 55 (see FIG. 7 ).
- the shell section 51 is a portion which is formed to be hollow while opening downward, and is put over the mouth 61 (see FIG. 15 ) of the bottle 60 upon the inner stopper 40 while covering the inner stopper 40 .
- the receiving section 52 is a portion which protrudes downward from an inner side upper surface of the shell section 51 , has a lower opening section, and receives the lid section 421 of the main body 41 in an inside thereof to surround an edge 421 b of the lid section 421 .
- the protrusion section 53 is a portion which has a rib shape protruding inward from an inner circumference surface of the receiving section 52 .
- the protrusion section 53 protrudes up to a position in which the protrusion section 53 interferes with the edge 421 b of the lid section 421 when the cap 50 and the inner stopper 40 are assembled.
- the screwing section 54 has a shape which protrudes in a cylindrical shape and downward from an inner side upper surface of the shell section 51 and opens downward.
- the female screw thread 541 which is screwed to the male screw thread 411 c formed on the outer circumference surface of the hollow section 411 of the inner stopper 40 is formed on an inner circumference surface of the screwing section 54 .
- the cap 20 is opened or closed with respect to the bottle 30
- it is configured such that the cap 50 is opened or closed with respect to the inner stopper 40 in terms of directly.
- FIG. 7 is a partially enlarged sectional view of a cap included in the cap assembly 1 B of the first embodiment illustrated in FIG. 6 .
- FIG. 8 is a partially enlarged sectional view illustrating a portion of the cap assembly 1 B of the first embodiment illustrated in FIG. 6 in a state in which the lid section 42 of the inner stopper 40 is received in the receiving section 52 of the cap 50 .
- the lid section 421 of the inner stopper 40 enters a space upper than the protrusion section 53 in the receiving section 52 of the cap 50 .
- the hooks 55 protruding inward are formed in a portion immediately above the protrusion section 53 and inside the receiving section 50 of the cap 50 .
- the hooks 55 are formed at plural locations with spaces with respect to a circumferential direction, respectively.
- FIG. 9 is a partially enlarged sectional view illustrating a portion of an edge 421 b of the lid section 421 in a section in which the lid section 421 is sectioned horizontally in a state in which the lid section of the inner stopper enters the receiving section of the cap.
- rotation preventing protrusions 421 d which are formed circumferentially in a circumferential direction on a circumference surface 421 c of the lid section 421 of the inner stopper 40 in large numbers.
- the rotation preventing protrusions 421 d engage with the hooks 55 to prevent a positional relation between the cap 50 and the inner stopper 40 from being deviated from a predetermined relation.
- FIG. 10 to FIG. 13 are explanatory views of a method for assembling of assembling the cap to the inner stopper in the cap assembly of the first embodiment which have been explained with reference to FIG. 6 to FIG. 9 .
- the inner stopper 40 is placed on a jig 70 which agrees with a shape of the inner stopper 40 .
- Ribs 411 e are formed on an inner circumference surface of the hollow section 411 in the inner stopper 40 , and the ribs 411 e are fitted in depressions (not illustrated in the drawings) of the jig 70 to prevent rotation.
- the cap 50 is put on, and with the cap 50 being fixed, the jig 70 is moved up in a direction of arrow U while being rotated in a direction of arrow R 1 as illustrated in FIG. 12 . Since the inner stopper 40 is prevented from rotating with respect to the jig 70 , the inner stopper 40 rotates together with the jig 70 , and the male screw thread 411 c of the inner stopper 40 is screwed to the female screw thread 541 of the screwing section 54 of the cap 50 . Then, the edge 421 b of the lid section 421 of the inner stopper 40 interferes with the protrusion 53 (see FIG.
- the receiving section 52 is expanded elastically by the lid section 421 of the inner stopper 40 , and when the lid section 421 goes beyond the protrusion section 53 and comes to a side of the upper surface of the shell section 51 , the receiving section 52 returns to an original shape.
- the protrusion section 53 plays a role in which the protrusion section 53 is positioned below the lid section 421 , and as described later, even after the junction section 422 is broken, the protrusion section 53 supports the lid section 421 to keep the lid section 421 in an inside of the receiving section 52 .
- the receiving section 52 is expanded and the torque to rotate the jig 70 increases, and when the lid section 421 goes beyond the protrusion section 53 , the torque quickly decreases. Accordingly, by monitoring the torque, it is possible to detect that the lid section 421 has gone beyond the protrusion section 53 . Or, instead of monitoring the torque, by using a rotation angle in the direction of arrow R 1 or a movement amount in the direction of arrow U of the jig 70 , it may be detected that the lid section 421 has gone beyond the protrusion section 53 .
- the jig 70 is moved downward in a direction of arrow D while the jig 70 is now inversely rotated in a direction of arrow R 2 , so that the lid section 421 is positioned immediately above the protrusion section 53 . Since the torque to rotate the jig 70 begins to increase when the lid section 421 abuts against the protrusion section 53 , it is possible to detect that the lid section 421 comes down up to immediately above the protrusion section 53 by monitoring the torque. Or, it may be detected that the lid section 421 reaches immediately above the protrusion section 53 by using a rotation angle in the direction of arrow R 2 , an amount of moving down in the direction of arrow D or the like.

There are included an inner stopper and a cap, and the inner stopper and the cap are assembled in a state in which a lid section is received in a receiving section and a protrusion section is positioned below the lid section, and the lid section is arranged at a position which is inside the receiving section and has a space between an inner surface of a shell section and the lid section, so that an occurrence of misunderstanding by torque changing before the inner stopper is opened is prevented.
Description
- The present invention is related to a cap assembly which is put over a mouth of a bottle and a method for assembling of the cap assembly.
- Conventionally, there have been used many containers of configuration in which, for example, a mouth of a bottle filled with food having fluidity such as mayonnaise, jam and the like is closed with an inner stopper, a seal and the like, and then a cap is put thereon. In a case of such configuration, in order to take a content from a bottle, operations such as removing a cap at first, and after that, opening a pull-tab of an inner stopper, or removing a seal are required, and so, it is pointed out that it may be difficult for an elderly person to remove the pull-tab, or the content of the bottle may stick to a hand or scatter around when removing the seal, and so on, and thus, the usability is poor.
- In order to improve this, in recent years, there has been proposed cap assemblies of configuration in which, when removing a cap initially, by rotating temporarily the cap in a direction opposite to a direction of removing to open an inner stopper and then rotating the cap in the direction of removing, it is possible to remove the cap in a state in which the inner stopper is opened (see, Patent Literatures 1, 2 and 3). According to the cap assemblies of the proposals, it is not required to open the inner stopper after removing the cap, and thus, the usability is much improved.

- Patent Literature 2: Japanese Laid-Open Patent Literature No. 2011-225220.
- Patent Literature 3: Japanese Patent No. 4581034.
- In a case of the cap assemblies of the above-described proposals, when a cap is rotated in a direction of closing which is opposite to a direction of removing in order to open the cap initially, the rotating temporarily becomes heavy and then becomes light, and however, an inner stopper is not opened yet at this stage, and thus, it is required that the cap is further rotated in the same direction to open the inner stopper, and then, the cap is now rotated in the direction of removing.
- However, at a stage in which the rotating becomes light after the rotating temporarily becomes heavy while rotating the cap in the closing direction, there may be a case in which misunderstanding that the inner stopper has been opened occurs, and thus, it is required to eliminate such misunderstanding.
- In view of the foregoing, it is an object of the present invention to provide a cap assembly which prevents an occurrence of the above-described misunderstanding when opening a cap initially and is easy to handle, and an assembly method thereof.
- A cap assembly according to the present invention to obtain the above-described object includes:
- an inner stopper that is put over a mouth of a bottle to close the mouth; and
- a cap that is put over the mouth such that the cap covers the inner stopper, wherein
- the inner stopper includes:
- a main body that includes a hollow section which has a hollow shape having an upper opening and a lower opening and communicating with the mouth of the bottle, and whose lower end section is inserted to the mouth of the bottle, and a holding section which holds an upper end section of the bottle in cooperation with the lower end section of the hollow section after the insertion has been executed; and
- a lid body that includes a lid section which spreads above the hollow section such that the lid section covers the hollow section, and a junction section which is junctioned circumferentially to an upper end edge of the hollow section and closes an opening on an upper end of the hollow section together with the lid section, and that is a component integrated with the main body, closes the mouth of the bottle together with the main body, and receives pressing from above to have the junction section broken so as to become a part separate from the main body,
- the cap includes:
- a shell section that is formed to be hollow while opening downward and is put over the mouth of the bottle while covering the inner stopper;
- a receiving section that protrudes downward from an inner side upper surface of the shell section, has a lower opening section, and receives the lid section in an inside to surround an edge of the lid section; and
- a protrusion section that protrudes inward from an inner circumference surface of the receiving section, interferes with the edge of the lid section to cause the lid section to expand the receiving section when the cap and the inner stopper are assembled, causes the receiving section to return to an original shape when the lid section comes to a side of an upper surface of the shell section so as to be positioned below the lid section, and supports the lid section after the junction section is broken, and
- the cap is coupled with the inner stopper in a state in which the cap receives the lid section in the receiving section, the protrusion section is positioned below the lid section, and the lid section is arranged at a position which is inside the receiving section and has a space between the lid section and the inner surface of the shell section.
- Since, in the cap assembly according to the present invention, the inner stopper and the cap respectively include the above-described configurations, and the cap is coupled with the inner stopper in a state in which the cap receives the lid section in the receiving section, the protrusion section is positioned below the lid section, and the lid section is arranged at a position which is inside the receiving section and has a space between the inner surface of the shell section and the lid section, the cap assembly according to the present invention does not have behaviors that cause a user to misunderstand like becoming temporarily heavy and then becoming light as the conventional cases when opening the inner stopper with the cap, and thus, the cap assembly according to the present invention has a configuration which is easy to handle.
- Here, in the cap assembly according to the present invention, it is preferable that the inner stopper includes a screw thread which circles helically on an outer circumference surface of the hollow section, and the cap includes a screwing section which protrudes in a cylindrical shape and downward from the inner side upper surface of the shell section, and has a lower opening section, and on whose inner circumference surface a screw thread to be screwed to the screw thread of the inner stopper is formed.
- In a case of this configuration, it is possible to assemble the inner stopper and the cap independently of a bottle.
- Or, in the cap assembly according to the present invention, it is acceptable that the cap includes on an inner surface of the shell section a screw thread to be screwed to a screw thread formed in the bottle.
- In addition, in the cap assembly according to the present invention, it is preferable that an upper end surface surrounding the upper opening and being oriented upward of the hollow section has a gradient rising outward.
- In a case of this configuration, when a bottle is inclined to pour a content in the bottle and then the bottle is stood up, the content is cut well, and thus, it is prevented that the content drips inadvertently.
- In addition, a method for assembling according to the present invention is a method for assembling of assembling the inner stopper and the cap included in the cap assembly according to the present invention, and includes putting the cap over the inner stopper, and causing the receiving section to receive the lid section up to a position in which the protrusion section goes beyond the lid section to be positioned below the lid section and the space between the lid section and the inner surface of the shell section becomes relatively narrow, and thereafter, moving the cap upward relatively to the inner stopper in a range in which a state in which the protrusion section is positioned below the lid section is maintained, so as to expand the space between the lid section and the inner surface of the shell section.
- According to the method for assembling, it is possible to make an arrangement in which the space between the lid section of the inner stopper and the inner surface of the shell section of the cap is securely expanded, and even in a case in which the cap is inadvertently pressed before opening, it is avoided that a force is applied to the lid section of the inner stopper, and thus, it is prevented that the inner stopper is inadvertently opened.
- According to the above present invention, misunderstanding that the inner stopper has been opened even though the inner stopper has not been opened yet when removing the cap initially is prevented, and thus, the usability is improved.

-
FIG. 1 is a vertical sectional view of a cap assembly of a comparative example. - A
cap assembly 1A of the comparative example illustrated in thisFIG. 1 includes ainner stopper 10 and acap 20. - The
inner stopper 10 is a component which is put over amouth 31 of abottle 30 to close themouth 31. In addition, thecap 20 is a component which is put over themouth 31 of thebottle 30 upon theinner stopper 10 such that thecap 20 covers theinner stopper 10. - This
FIG. 1 illustrates a state in which theinner stopper 20 is already capped to themouth 31 of thebottle 30, thecap 20 is put upon theinner stopper 10 and is in a predetermined relation with respect to theinner stopper 10. - The
inner stopper 10 includes amain body 11 and alid body 12. - The
main body 11 includes ahollow section 111 and aholding section 112. Of them, thehollow section 111 has a hollow shape which has an upper opening and a lower opening, and communicates with themouth 31 of thebottle 30, and alower end section 111 a of thehollow section 111 is inserted to themouth 31 of thebottle 30. - In addition, the holding
section 112 included in themain body 11 plays a role of receiving an insertion of anupper end section 32 of thebottle 30 to hold theupper send section 32 of thebottle 30 in cooperation with thelower end section 111 a of thehollow section 111 whichlower end section 111 a is inserted to themouth 31 of thebottle 30. The holdingsection 112 has a configuration in which arib 112 a is formed to protrude inward in theholding section 112, and therib 112 a enters adepressed section 33 of thebottle 30 so that the holdingsection 112 firmly holds theupper end section 32 of thebottle 30 and is not removed from themouth 31 of thebottle 30. - In addition, the
lid body 12 included in theinner stopper 10 includes alid section 121 and ajunction section 122. Of them, thelid section 121 is a portion which spreads in a plate shape and above thehollow section 111 such that thelid section 121 covers thehollow section 111. In addition, thejunction section 122 is junctioned circumferentially to anupper end edge 111 b of thehollow section 111, and closes an opening on an upper end of thehollow section 111 together with thelid section 121. Themain body 11 and thelid body 12 which are included in theinner stopper 10 are integrally formed as a single component, and however, thejunction section 122 is easily broken when thelid section 121 is pressed from above, and when thejunction section 122 is broken, thelid body 12 becomes a part separate from themain body 11. This point will be described later. - In order to secure a safety margin ratio such that the
junction section 122 is not inadvertently broken, it is devised such that arecess 121 a is formed on an upper surface of thelid section 121 so that thelid section 121 is made to have a shape of being away from an upper surface of thecap 20, and even if a force is applied to the upper surface of thecap 20 and the upper surface is depressed, the force is not applied to thelid section 121. - In addition, the
cap 20 included in thecap assembly 1A of the comparative example includes ashell section 21, a receivingsection 22 and aprotrusion section 23. - The
shell section 21 is a portion which is formed to be hollow while opening downward, and is put over themouth 31 of thebottle 30 upon theinner stopper 10 while covering theinner stopper 10. Afemale screw thread 211 which is screwed to amale screw thread 34 provided in thebottle 30 is formed on an inner circumference surface of theshell section 21, and thecap 20 is rotated to be attached or removed. - In addition, the receiving
section 22 is a portion which protrudes downward from an inner side upper surface of theshell section 22, has a lower opening section, and receives thelid section 121 of themain body 11 in an inside thereof to surround anedge 121 b of thelid section 121. - Further, the
protrusion section 23 is a portion which has a shape of rib protruding inward from an inner circumference surface of the receivingsection 22. As described later, theprotrusion section 23 protrudes up to a position where theprotrusion section 23 interferes with theedge 121 b of thelid section 121. - In order to attach the
cap assembly 1A having the configuration illustrated in thisFIG. 1 to thebottle 30, after thebottle 30 is filled with a content, theupper end section 32 of thebottle 30 is held between a lower end section of thehollow section 11 of theinner stopper 10 and theholding section 112. In other words, theinner stopper 10 is capped to thebottle 30. After this capping, thecap 20 is put thereover and rotated, and thecap 20 is attached such that theprotrusion section 23 of thecap 20 comes to a position immediately above thelid section 121 of theinner stopper 20, as illustrated inFIG. 1 . Then, shrink wrap packaging and the like are performed, and thecap 20 becomes a state in which thecap 20 is not rotated inadvertently from the position illustrated in thisFIG. 1 . -
FIG. 2 toFIG. 4 are views illustrating behaviors at the time of opening by a consumer as to the comparative example illustrated inFIG. 1 - After delivered to a consumer in the state illustrated in
FIG. 1 , when the consumer is going to open the cap initially, after the consumer removes the shrink wrap at first, the consumer rotates the cap in a direction of closing further. Then, thecap 20 moves in a direction indicated by arrow A illustrated inFIG. 2 , and thelid section 121 moves and comes upper than theprotrusion section 23 while theedge 121 b of thelid section 121 of theinner stopper 10 interferes with theprotrusion section 23 of thecap 20 to expand the receivingsection 22 elastically, as illustrated inFIG. 2 . Then, the interference between theedge 121 b of thelid section 121 and theprotrusion section 23 of thecap 20 is released and the receivingsection 22 returns to an original shape, and theprotrusion section 23 of thecap 20 comes below theedge 121 b of thelid section 121. - When the
cap 20 is further rotated in the direction of closing so that thecap 20 is further moved in the direction of arrow A, thecap 20 presses thelid section 121, and thejunction section 122 is broken, as illustrated inFIG. 3 . When thecap 20 is rotated in the direction of closing and becomes the state illustrated inFIG. 3 , thecap 20 becomes not further rotating in the direction of closing, and then, thecap 20 is now rotated in a direction of opening. Then, as illustrated inFIG. 4 , thelid section 12 is removed from thebottle 30 together with thecap 20 while only thelid section 12 of theinner stopper 10 is separated from themain body 11 and remains entering the receivingsection 22 of thecap 20. Since theprotrusion section 23 is formed in thecap 20, thelid section 20 thereafter remains entering the receivingsection 22 of thecap 20. - In the case of the comparative example illustrated in these
FIG. 1 toFIG. 4 , it is possible to open theinner stopper 10 by rotating temporarily thecap 20 in the direction of closing when opening thecap 20 initially, such an action to open an inner stopper after opening a cap is not required, and thus, the usability is much improved. -
FIG. 5 is a view illustrating torque changes when thecap 20 is rotated temporarily in a direction of closing in order to open thecap 20 initially in the comparative example illustrated inFIG. 1 toFIG. 4 . - When the shrink wrap is removed and the
cap 20 is rotated in the direction of closing, thecap 20 moves in a direction indicated by arrow A illustrated inFIG. 2 , theedge 121 b of thelid section 121 of theinner stopper 10 interferes with theprotrusion section 23 of thecap 20 to expand the receiving section. At this moment, as illustrated in region a ofFIG. 5 , a force (torque) to rotate thecap 20 increases. When thecap 20 is further rotated in the direction of closing, thelid section 121 moves and comes upper than thelid section 23 and the torque temporarily decreases (region b). When the cap is further rotated in the direction of closing, thecap 20 now presses thelid section 121, and when thecap 20 is furthermore rotated in the direction of closing, thejunction section 122 is broken while the torque is increasing (region c). Then, thecap 20 becomes not rotating in the direction of closing, and then, thecap 20 is now rotated in the direction of opening, so that thecap 20 is removed. - Here, as seen from this
FIG. 5 , in the case of the above-describedcap assembly 1A of the comparative example, when thecap 20 is rotated in the direction of closing in order to open theinner stopper 10, there is a peak P of the torque before the cap abuts against thelid section 121 of the inner stopper. For this reason, a consumer who is not familiar to handling a bottle to which thecap assembly 1A is attached may misunderstand that theinner stopper 10 has been opened based on that the peak P of the torque has passed, and at this point, the consumer accordingly rotates thecap 20 in the direction of opening, and then the consumer notices that theinner stopper 10 has not been opened yet after opening thecap 20. Even if noticing that theinner stopper 10 has not been opened yet after opening thecap 20, such an inexperienced consumer may not notice that theinner stopper 10 is not opened before proceeding up to region c, and thus, a complaint as a defective product may be raised. - Based on the above explanations of the comparative example, embodiments according to the present invention will be explained next.
-
FIG. 6 is a vertical sectional view of a cap assembly of a first embodiment according to the present invention. - A
cap assembly 1B of the first embodiment includes aninner stopper 40 and acap 50. - The
inner stopper 40 is a component which is put over amouth 61 of abottle 60 to close the mouth 61 (seeFIG. 14 ). In addition, thecap 50 is a component which is put over themouth 61 of thebottle 60 upon theinner stopper 40 such that thecap 50 covers theinner stopper 40. - The
inner stopper 40 includes amain body 41 and alid body 42. - The
main body 41 includes ahollow section 411 and aholding section 412. Of them, thehollow section 411 has a hollow shape which has an upper opening and a lower opening and communicates with themouth 61 of thebottle 60, and at the time of capping, alower end section 411 a thereof is inserted to themouth 61 of the bottle 60 (seeFIG. 15 ). - In addition, a
male screw thread 411 c which circles helically on an outer circumference surface of thehollow section 411 and is screwed to afemale screw thread 541 of thecap 50 is formed on the outer circumference surface in thehollow section 411. - In addition, the holding
section 412 included in themain body 41 plays a role of receiving an insertion of anupper end section 62 of thebottle 60 to hold theupper end section 62 of thebottle 60 in cooperation with thelower end section 411 of thehollow section 411 whichlower end section 411 a is inserted to the mouth of thebottle 60. The holdingsection 412 has a configuration in which arib 412 a is formed in theholding section 412, and therib 412 a enters a depressed section 63 (seeFIG. 14 ) of thebottle 60 so that the holdingsection 412 firmly holds theupper end section 62 of thebottle 60 and is not removed from themouth 61 of thebottle 60. - In addition, the
lid body 42 included in theinner stopper 40 includes alid section 421 and ajunction section 422. Of them, thelid section 421 is a portion which spreads in a plate shape above thehollow section 411 such that thelid section 421 covers thehollow section 411. In addition, thejunction section 422 is junctioned circumferentially to anupper end edge 411 b of thehollow section 411, and closes an opening on an upper end of thehollow section 411 together with thelid section 421. Themain body 41 and thelid body 42 which are included in thehollow section 40 are integrally formed as a single component, and however, thejunction section 422 is considerably easily broken when thelid section 421 is pressed from above. When thejunction section 422 is broken, thelid body 42 becomes a part separate from themain body 41. - In order to secure a safety margin ratio as large as possible such that the
junction section 422 is not broken inadvertently, it is devised such that arecess 421 a is formed on an upper surface of thelid section 421 so that thelid section 421 is made to be away as much as possible from an upper surface of thecap 50, and thus, even if a force is applied to the upper surface of thecap 50 and the upper surface is depressed, the force is not applied to thelid section 421. - The
cap 50 includes ashell section 51, a receivingsection 52, aprotrusion section 53, a screwingsection 54 which are illustrated inFIG. 6 , and further, hooks 55 (seeFIG. 7 ). - The
shell section 51 is a portion which is formed to be hollow while opening downward, and is put over the mouth 61 (seeFIG. 15 ) of thebottle 60 upon theinner stopper 40 while covering theinner stopper 40. - In addition, the receiving
section 52 is a portion which protrudes downward from an inner side upper surface of theshell section 51, has a lower opening section, and receives thelid section 421 of themain body 41 in an inside thereof to surround anedge 421 b of thelid section 421. - Further, the
protrusion section 53 is a portion which has a rib shape protruding inward from an inner circumference surface of the receivingsection 52. Theprotrusion section 53 protrudes up to a position in which theprotrusion section 53 interferes with theedge 421 b of thelid section 421 when thecap 50 and theinner stopper 40 are assembled. - In addition, the screwing
section 54 has a shape which protrudes in a cylindrical shape and downward from an inner side upper surface of theshell section 51 and opens downward. Thefemale screw thread 541 which is screwed to themale screw thread 411 c formed on the outer circumference surface of thehollow section 411 of theinner stopper 40 is formed on an inner circumference surface of the screwingsection 54. In other words, in the above-described comparative example, thecap 20 is opened or closed with respect to thebottle 30, and in contrast, in the case of thecap assembly 1B of the first embodiment, it is configured such that thecap 50 is opened or closed with respect to theinner stopper 40 in terms of directly. -
FIG. 7 is a partially enlarged sectional view of a cap included in thecap assembly 1B of the first embodiment illustrated inFIG. 6 . - In addition,
FIG. 8 is a partially enlarged sectional view illustrating a portion of thecap assembly 1B of the first embodiment illustrated inFIG. 6 in a state in which thelid section 42 of theinner stopper 40 is received in the receivingsection 52 of thecap 50. - In the case of the
cap assembly 1B of the first embodiment, as illustrated inFIG. 6 andFIG. 8 , thelid section 421 of theinner stopper 40 enters a space upper than theprotrusion section 53 in the receivingsection 52 of thecap 50. However, there is formed a space between an inner surface of an upper section of theshell section 51 and thelid section 422 such that the space is opened to an extent in which even if a force is applied to theshell section 51 from above and theshell section 51 is depressed slightly, the force is not applied to thelid section 421. - In addition, as illustrated in
FIG. 7 , thehooks 55 protruding inward are formed in a portion immediately above theprotrusion section 53 and inside the receivingsection 50 of thecap 50. Thehooks 55 are formed at plural locations with spaces with respect to a circumferential direction, respectively. -
FIG. 9 is a partially enlarged sectional view illustrating a portion of anedge 421 b of thelid section 421 in a section in which thelid section 421 is sectioned horizontally in a state in which the lid section of the inner stopper enters the receiving section of the cap. - As illustrated in this
FIG. 9 , there are includedrotation preventing protrusions 421 d which are formed circumferentially in a circumferential direction on a circumference surface 421 c of thelid section 421 of theinner stopper 40 in large numbers. Therotation preventing protrusions 421 d engage with thehooks 55 to prevent a positional relation between thecap 50 and theinner stopper 40 from being deviated from a predetermined relation. -
FIG. 10 toFIG. 13 are explanatory views of a method for assembling of assembling the cap to the inner stopper in the cap assembly of the first embodiment which have been explained with reference toFIG. 6 toFIG. 9 . - At first, as illustrated in
FIG. 10 , theinner stopper 40 is placed on ajig 70 which agrees with a shape of theinner stopper 40.Ribs 411 e are formed on an inner circumference surface of thehollow section 411 in theinner stopper 40, and theribs 411 e are fitted in depressions (not illustrated in the drawings) of thejig 70 to prevent rotation. - Next, as illustrated in
FIG. 11 , thecap 50 is put on, and with thecap 50 being fixed, thejig 70 is moved up in a direction of arrow U while being rotated in a direction of arrow R1 as illustrated inFIG. 12 . Since theinner stopper 40 is prevented from rotating with respect to thejig 70, theinner stopper 40 rotates together with thejig 70, and themale screw thread 411 c of theinner stopper 40 is screwed to thefemale screw thread 541 of the screwingsection 54 of thecap 50. Then, theedge 421 b of thelid section 421 of theinner stopper 40 interferes with the protrusion 53 (seeFIG. 7 ) formed on the inner circumference surface of the receivingsection 52 of thecap 50, and thus, the receivingsection 52 is expanded elastically by thelid section 421 of theinner stopper 40, and when thelid section 421 goes beyond theprotrusion section 53 and comes to a side of the upper surface of theshell section 51, the receivingsection 52 returns to an original shape. With this, theprotrusion section 53 plays a role in which theprotrusion section 53 is positioned below thelid section 421, and as described later, even after thejunction section 422 is broken, theprotrusion section 53 supports thelid section 421 to keep thelid section 421 in an inside of the receivingsection 52. - When the
lid section 421 rides on theprotrusion section 53, the receivingsection 52 is expanded and the torque to rotate thejig 70 increases, and when thelid section 421 goes beyond theprotrusion section 53, the torque quickly decreases. Accordingly, by monitoring the torque, it is possible to detect that thelid section 421 has gone beyond theprotrusion section 53. Or, instead of monitoring the torque, by using a rotation angle in the direction of arrow R1 or a movement amount in the direction of arrow U of thejig 70, it may be detected that thelid section 421 has gone beyond theprotrusion section 53. - Here, only by rotating the
jig 70 and theinner stopper 40 in the direction of arrow R1 illustrated inFIG. 12 , it is difficult to hold thelid section 421 at a position beyond theprotrusion section 53 and immediately above theprotrusion section 53, and thus, thelid section 421 results in going upward excessively in the receivingsection 52. - Then next, as illustrated in
FIG. 13 , thejig 70 is moved downward in a direction of arrow D while thejig 70 is now inversely rotated in a direction of arrow R2, so that thelid section 421 is positioned immediately above theprotrusion section 53. Since the torque to rotate thejig 70 begins to increase when thelid section 421 abuts against theprotrusion section 53, it is possible to detect that thelid section 421 comes down up to immediately above theprotrusion section 53 by monitoring the torque. Or, it may be detected that thelid section 421 reaches immediately above theprotrusion section 53 by using a rotation angle in the direction of arrow R2, an amount of moving down in the direction of arrow D or the like. - In the
cap assembly 1B of the first embodiment, through such assembling procedures described above, thecap 50 and theinner stopper 40 are coupled with each other in a state in which thecap 50 receives thelid section 421 in the receivingsection 52 and theprotrusion section 53 is positioned below thelid section 421, and thelid section 421 is arranged at a position which is in the inside of the receivingsection 52 and has a space between thelid section 421 and the inner surface of theshell section 51. - Here, in the state in which the
lid section 421 is immediately above theprotrusion section 53, as illustrated inFIG. 9 , therotation preventing protrusions 421 d engage with thehooks 55, and thus, theinner stopper 40 and thecap 50 are not rotated inadvertently by such a degree as a vibration at the time of transportation, and thus, the positional relation thereof is maintained. - Incidentally, as illustrated in
FIG. 7 andFIG. 8 , thehooks 55 for rotation prevention are provided only in a portion immediately above theprotrusion section 53, and not provided in a portion further above in the receivingsection 52. This is because, when thecap 50 is closed again, after delivered to a consumer and thecap 50 is opened together with thelid body 42 of theinner stopper 40, if therotation preventing protrusions 421 d remain engaging with thehooks 55, closing thecap 50 results in becoming heavy, and thus, when thecap 50 is closed again, thelid section 421 moves to an upper area where thehooks 55 are not provided, and thus, it is possible to close thecap 50 with a small force. - Incidentally, the example in which the
jig 70 and theinner stopper 40 are rotated and moved vertically has been explained in here, and however, a jig (not illustrated in the drawings) to hold thecap 50 may be rotated or moved vertically with theinner stopper 40 being fixed. - As described above, in the
cap assembly 1B of the first embodiment, theinner stopper 40 and thecap 50 are assembled before being capped to a bottle. In other words, assembling of thecap assembly 1B may be performed at a side of a manufacturer of thecap assembly 1B. The assembling of theinner stopper 40 and thecap 50 is required to be performed under a substantially high precision control. The respect that the assembling may be performed at a side of a manufacturer of thecap assembly 1B accordingly does not put a burden of manufacturing facilies on a side of manufacturer which fills thebottle 30 with a content and caps thebottle 30 from a technical viewpoint for the assembling, and thus, the first embodiment is preferable also in this respect. - Next, a scene in which the cap assembly is capped to a bottle will be explained.
-
FIG. 14 andFIG. 15 are explanatory views of a scene in which the cap assembly of the first embodiment is capped to a bottle. - The
bottle 60 is filled with a content, and, as illustrated inFIG. 14 , thecap assembly 1B is pressed down, for example, with aflat plate 80 being put thereon, while the state in which theinner stopper 40 and thecap 50 are coupled with each other is maintained. Then, as illustrated inFIG. 15 , theupper end section 62 of thebottle 60 enters between thelower end section 411 a of thehollow section 41 of theinner stopper 40 and theholding section 412, therib 412 a formed in theholding section 412 enters thedepressed section 63 of thebottle 60, and thus, theinner stopper 40 is firmly fixed to themouth 61 of thebottle 60. - After the
cap assembly 1B is capped to thebottle 60, shrink wrap packaging is performed. -
FIG. 16 andFIG. 17 are explanatory views of a scene in which the cap is opened initially. - A product is delivered to a consumer, in the state illustrated in
FIG. 15 . - After the consumer opens the shrink wrap, the consumer temporarily rotates the
cap 50 in the direction of closing. Then, as illustrated inFIG. 16 , thecap 50 presses down thelid section 42 of theinner stopper 40, and with this, thejunction section 421 b is broken. Then, when thecap 50 is rotated in the direction of opening, as illustrated inFIG. 17 , thecap 50 is removed while thelid section 421 of theinner stopper 40 is kept in the receivingsection 52 of thecap 50. At this moment, the mouth of heinner stopper 40 is in a state of opened already. - Incidentally, the
upper end surface 411 d being oriented upward and surrounding the upper opening of theinner stopper 40 is formed to be a surface which has a gradient rising outward, as illustrated inFIG. 8 . Theupper end surface 411 d having the gradient rising outward has an effect that when thebottle 60 is inclined to pour a content thereof and then is stood up, the content is cut well, and thus, it is prevented that the content drips inadvertently. -
FIG. 18 is a view illustrating torque changes when thecap 50 is rotated temporarily in the direction of closing in order to open thecap 50 initially in the first embodiment illustrated inFIG. 6 toFIG. 17 . ThisFIG. 18 is a view which is compared toFIG. 5 in the above-described comparative example. - In the case of the
cap assembly 1B of the first embodiment, the peak P of the torque illustrated inFIG. 5 is passed when theinner stopper 40 and thecap 50 are assembled, and in the state in which theinner stopper 40 and thecap 50 have been assembled, thelid section 421 of theinner stopper 40 is inside the receivingsection 52 of thecap 50 and on a side of the upper surface of thecap 50 than theprotrusion section 53. Accordingly, the peak P of the torque illustrated inFIG. 5 does not appear at a stage in which thecap 50 is opened initially, and it is when thecap 50 presses thelid section 421 that the force (torque) to rotate thecap 50 increases. For this reason, there is avoided such an occurrence that a consumer who is trying to open theinner stopper 40 and remove thecap 50 is caused to misunderstand that theinner stopper 40 has been opened, thereby providing the consumer with a feeling of safety, and thus, a cap assembly having good usability is obtained. - Next, a cap assembly of a second embodiment according the present invention will be explained. Since the cap assembly of the second embodiment may be easily understood when being compared to the above-described comparative example, elements corresponding to the respective elements of the
cap assembly 1A according to the comparative example will be illustrated while denoted with reference signs same as those denoted in the drawings (FIG. 1 toFIG. 4 ) of thecap assembly 1A of the comparative example even if there are some slight differences as to shapes and the like, and only differences will be explained. -
FIG. 19 is a vertical sectional view of a cap assembly of the second embodiment according to the present invention. - In a cap assembly 1C of the second embodiment, a
cap 20 is coupled with aninner stopper 10 in a state in which thecap 20 receives alid section 121 in a receivingsection 22 and aprotrusion section 23 is positioned below thelid section 121, and thelid section 121 is arranged at a position which is in an inside of the receivingsection 22 and has a space between an inner surface of ashell section 21 and thelid section 121. - In order to obtain this, in the case of the cap assembly 1C of the second embodiment illustrated in
FIG. 19 , a size of the receivingsection 22 is determined such that a sufficiently wide space is secured between thelid section 121 and theshell section 21 even when thelid section 121 is received upper than theprotrusion section 23 in the receivingsection 22. - In the cap assembly 1C of the second embodiment, in order to assemble the
inner stopper 10 and thecap 20, similarly to the comparative example, there are used such procedures that after thebottle 30 is filled with a content and is capped with theinner stopper 10, and then thecap 20 is attached. In order to attach thecap 20 to theinner stopper 10 which has been capped, areal bottle 30 is used instead of thejig 70 illustrated inFIG. 10 toFIG. 13 , and there is used the method for assembling explained with reference toFIG. 10 toFIG. 13 , that is, a method for assembling in which after thelid section 121 is moved up to the side of the upper surface of thelid section 21 where thelid section 121 goes beyond theprotrusion section 23 in the receivingsection 22, thecap 20 is then inversely rotated so that thelid section 121 is positioned immediately above theprotrusion section 23. - When the cap assembly 1C is assembled as illustrated in
FIG. 19 , it is packaged together with thebottle 30 by shrink wrap packaging, and with this, thecap 20 may not be rotated and becomes a state in which a position thereof with respect to theinner stopper 10 is fixed. -
FIG. 20 andFIG. 21 are explanatory views of a scene in which the cap is opened initially in the cap assembly 1C of the second embodiment. - A product is to be delivered to a consumer, in the state illustrated in
FIG. 19 . - After opening the shrink wrap, the consumer temporarily rotates the
cap 20 in the direction of closing. Then, as illustrated inFIG. 20 , thecap 20 presses down thelid section 12 of theinner stopper 10, and with this, thejunction section 121 b is broken. Then, when thecap 20 is rotated in the direction of opening, as illustrated inFIG. 21 , thecap 20 is removed while thelid section 121 of theinner stopper 10 is kept in the receivingsection 22 of thecap 20. At this moment, the mouth of theinner stopper 10 is in a state of already opened. - Also in the case of the cap assembly 1C of the second embodiment, similarly to the
cap assembly 1B of the above-described first embodiment, the peak P of the torque illustrated inFIG. 5 is passed when theinner stopper 10 and thecap 20 are assembled, and in the state in which theinner stopper 10 and thecap 20 have been assembled, thelid section 121 of theinner stopper 10 is inside the receivingsection 22 of thecap 20 and on the side of the upper surface of thecap 20 than theprotrusion section 23. Accordingly, at the stage when the cap is initially opened, the peak P of the torque illustrated inFIG. 5 does not appear, and it is when thecap 20 presses thelid section 121 that the force (torque) to rotate thecap 20 increases. For this reason, there is avoided such an occurrence that a consumer who is going to open theinner stopper 10 and remove thecap 20 is caused to misunderstand that theinner stopper 10 has been opened, thereby providing the consumer with a feeling of safety, and thus, a cap assembly having good usability is obtained. -
