Description

  The present invention relates to a cap having an unauthorized opening prevention function, and a bottle to which the unauthorized opening prevention function works effectively by attaching the cap.

  Conventionally, there are caps that prevent unauthorized opening. For example, as shown in Patent Document 1, a lid for preventing unauthorized opening is known. When this closure is applied for the first time to the neck of the lid (bottle), the band is elastically held by the neck ring, and when it is opened, the fragile means breaks and breaks. By remaining in the neck ring of the lid, it is prevented from opening without permission.

JP-A-2-72064

  In the closure shown in Patent Document 1, since the inner diameter of the band and the lid member is almost the same, when the lid member and the band are engaged with the bottle, the band hits and comes off properly. Unauthorized opening prevention function may not be exhibited. Therefore, there is a demand for a cap or bottle that can be smoothly closed without engaging the male threaded portion of the bottle when the lid member is engaged with the bottle, and that the function of preventing unauthorized opening is firmly demonstrated. It was.

  In addition, it is necessary to remove the bandage when disposing of the bottle. If the material differs between the bottle and the bandage, it takes time to separate the garbage. In addition, the protruding portion of the band portion was detached from the neck ring of the bottle and could not be firmly locked.

  An object of this application is to provide the form which can be closed smoothly and has the function of preventing a tampering, and the ring body can be appropriately locked.

  In view of the above problems, the cap of the present invention is a lid that is screwed onto and covers the neck of the bottle, a ring that is positioned below the lid and is locked to the neck ring formed on the neck, The ring body includes a connection portion that connects the lid body and the ring body, and the ring body includes a top plate portion that extends horizontally from below the lid body, and a side wall that extends from the outer peripheral end of the top plate portion. And a plurality of holes that are formed by opening the side wall portion and inclined in the inner circumferential direction, and the side wall portion is located outward from the outer peripheral surface of the lid body. And

  In addition, the ring body has a notch part in which a part in the circumferential direction is notched, and the connection part is connected at a plurality of positions aligned in the circumferential direction of the ring body, The first connection portion that breaks, and the second connection portion that is located behind the first connection portion in the opening rotation direction with respect to the cutout portion and that has a larger diameter than the first connection portion. Is preferred.

  Moreover, it is preferable that the inner peripheral surface of the top plate portion of the ring body has an inclined contact portion, and the inner surface of the top plate portion is formed with an inclined surface inclined upward.

  A protrusion protruding downward from the lower end of the lid, the protrusion being formed at a notch position formed in the ring body, and a protrusion length of the protrusion between the lid body and the ring body; It is preferable that the length is substantially the same.

  Further, the bottle whose neck is closed by the cap described above is formed on the entire circumference of the neck by protruding outward from the screw thread and the outer diameter of the screw thread in the same order as or more than the outer diameter. It has a step part and a neck ring having an outer diameter that projects outwardly to be equal to or larger than the outer diameter of the lid.

  In the first aspect of the present invention, the ring body projects more outward than the lid body, so that when the lid body is closed by the lid body, the ring body does not hit the neck of the bottle and can be smoothly closed. In addition, the neck ring protrudes outward, so that the locking of the ring body can be ensured, and the ring body and the lid body can be distinguished from the external appearance, so that the person who closes the cap can connect the neck ring and the ring body. The locked state is confirmed to make it easier to grasp the function to prevent unauthorized opening.

  According to the second aspect of the present invention, the ring body can be removed from the bottle together with the lid body, since the second connection part that is less likely to be fractured than the first connection part is not broken by the opening operation. By separating the ring body by the two connecting portions, it is possible to easily separate and discard the waste.

  According to a third aspect of the present invention, the ring body can be positioned and held on the stepped portion and the neck ring by the contact of the contact portion and the inclined surface, and the neck ring is sandwiched between the claw and the inclined surface, so that the ring body is It can be properly locked to the ring.

  In the invention according to claim 4, the upper rear end in the opening rotation direction of the ring body in contact with the protrusion during the opening operation restricts the elastic deformation near the upper rear end, and the connection near this Breakage due to the opening operation of the part can be prevented.

  In the invention according to claim 5, by attaching the above-mentioned cap to the neck portion, it is possible to appropriately ensure the unauthorized opening prevention function by the resistance of the claw elastically contacting the neck ring during the opening operation and the breaking resistance of the connection portion. Bottles can be provided.

  Embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, the first embodiment includes a bottle 20 having a neck ring 22 at a neck portion 21 and a cap 1 that closes the neck portion 21. Although the description will be made with the cap 1 as the upper side and the bottom side as the lower side with reference to the bottle 20, this vertical direction is for convenience of description and does not specify or limit the upper and lower sides of the usage state.

  The bottle 20 is in the form of a bottle comprising a hollow bottle body 20a and a shoulder 20b at the top of the bottle body, and has a neck portion 21 having an opening 21a that is open at the top. The neck portion 21 is formed with a screw thread 23 on its outer peripheral surface, and a step 24 formed around the neck portion 21 is disposed below the screw thread 23 so as to be raised to the same extent as the screw thread 23. A neck ring 22 protruding in a ring shape outward from the step portion 24 is formed below the step portion 24.

  As shown in FIGS. 1 and 2, the neck ring 22 and the step portion 24 are both formed in an annular shape around the entire circumference of the neck portion 21, and the upper surface of the neck ring 22 is continuously formed from the lower surface of the step portion 24. . As shown in FIG. 2, the outer diameter of the neck ring 22 is larger than the outer diameter of the step portion 24, and the outer diameter of the bottle body 20a is further larger. The upper surface of the neck ring 22 is inclined so as to be positioned higher on the inner periphery.

  As shown in FIGS. 1 and 2, the cap 1 includes a lid body 2 that covers the neck portion 21 of the bottle 20, and a ring body 3 that is connected to the lower portion of the lid body 2 by connecting portions 10 and 11. The cap 1 is made of, for example, a synthetic resin material.

  The lid body 2 includes a top portion 6 that covers the opening 21 a and a cylindrical portion 7 that covers the outer peripheral surface of the neck portion 21. The top portion 6 has a circular plate shape, and the outer diameter is equal to or larger than the outer diameter of the thread 23 of the neck portion 21. The cylindrical portion 7 is concentric with the top portion 6 and has a cylindrical shape extending downward from the outer peripheral end thereof. 2 and 3, the cap 1 is attached to and detached from the bottle 20 by rotating around an axis along the top and bottom. It is free.

  The ring body 3 is a ring-shaped body having a side wall portion 14 which is an outer peripheral surface located further outward than the outer peripheral surface of the lid body 2, and is substantially C-shaped having a notch portion 4 in a part in the circumferential direction. belongs to. The ring body 3 has a top plate portion 13 that extends outward from the lower side of the lid body 2 in the horizontal direction, and a side wall portion 14 that extends vertically downward from the outer peripheral end of the top plate portion 13 and extends downward. Have. By having the top plate portion 13, the side wall portion 14 of the ring body 3 is positioned outside the outer peripheral surface of the lid body 2.

  The ring body 3 is formed with a notch 4 with a part cut away, and the notch 4 is formed from the upper end to the lower end of the ring body 3. Specifically, the cutout portion 4 is formed with the same width from the top plate portion 13 of the ring body 3 to the height of about one-half of the side wall portion 14, and thereafter is formed so as to spread radially downward. Is done. A projection 8 is formed at a position where the cutout portion 4 is disposed and a thickness portion of the top plate portion 13 so as to protrude downward from the lower end of the cylindrical portion 7. The protrusion 8 is rounded downward and protrudes with a vertical dimension slightly smaller than the gap between the lid body 2 and the ring body 3.

  The lid body 2 and the ring body 3 are connected by connection portions 10 and 11. The connecting portions 10 and 11 are conical members having a narrow upper portion formed continuously from the lower surface of the lid body 2 to the upper surface of the ring body 3. As shown in FIG. 3, the lid body 2 and the ring body 3 are connected by the connecting portions 10 and 11, but the portions other than the connecting portions 10 and 11 are opened (gap). In the state where the lid 2 is closed, the upper edge of the stepped portion 24 is located on the inner peripheral side with respect to the connecting portions 10 and 11.

  As shown in FIGS. 4 and 5, the connecting portions 10 and 11 are arranged in the gap between the lid body 2 and the ring body 3 and connect the two. The connection portions 10 and 11 are a plurality of first connection portions 10 and 10 arranged along the opening rotation direction S from the protrusion 8, and are positioned behind the first connection portion 10 in the opening rotation direction S and are first. The second connection portion 11 is thicker than the connection portion 10.

  As shown in FIG. 6, when the lid body 2 is opened in a state where the ring body 3 is locked to the neck ring 22 by the unauthorized opening prevention means described later, the connecting portions 10 and 11 are broken, and this breaking resistance causes Prevents unauthorized opening. By forming the second connection portion 11 thicker than the first connection portion 10, it is difficult to be broken by the opening operation of the lid body 2, and the cap 1 is removed from the bottle 20 in a state where the ring body 3 is connected to the lid body 2. Can be removed. Thereby, the ring body 3 can be separated from the bottle 20 and easily separated and discarded, and the opening and closing after the second time can be performed only by the lid body 2.

  The first connection parts 10 and 10 have a narrow cone shape at the top, and are arranged at substantially equal intervals in the opening rotation direction S, for example, having five. The horizontal cross-sectional shape of the 1st connection part 10 is a half-moon shape which dented the inner peripheral side of the cap 1 in circular arc shape, and it swells to a circumferential direction and an outer periphery as the lower end side. As shown in FIG. 6, the first connection portion 10 has the upper end of the cone as a broken portion that separates the ring body 3 from the lid body 2.

  The 2nd connection part 11 is located in the vicinity of the protrusion 8, as shown in FIG.2 and FIG.4. The 2nd connection part 11 is separated from the 1st connection part 10 which adjoins by the substantially same dimension as the space | interval of the 1st connection parts 10 and 10. FIG. The second connection portion 11 has a semicircular cone shape substantially similar to the first connection portion 10, and is thicker than the first connection portion 10, so that it is less likely to be broken than the first connection portion 10, and can be opened. Hard to break.

  Similarly to the first connection portion 10, the second connection portion 11 uses the upper end of the cone as a broken portion that separates the ring body 3 from the lid body 2. Since the upper ends of the first connection portion 10 and the second connection portion 11 are the broken portions, the broken pieces of the first connection portion 10 and the second connection portion 11 do not remain at the lower end of the cylindrical portion 7, and the ring body 3 is separated. The cap 1 can improve the touch and appearance of the lower end of the lid 2.

  As described above, the ring body 3 includes the substantially horizontal top plate portion 13 and the side wall portion 14 extending from the outer peripheral end of the top plate portion 13. The ring body 3 is connected to the connection portions 10 and 11 on the inner peripheral side of the top plate portion 13. As shown in FIG. 8, a contact portion 17 is formed on the top plate portion 13 so as to contact the outer periphery of the step portion 24.

  Due to the top plate portion 13, the side wall portion 14 of the ring body 3 has an outer diameter and an inner diameter located outside the outer diameter and inner diameter of the lid body 2. Since the ring body 3 protrudes more outward than the lid body 2, the ring body 3 does not hit the neck portion 21 when the lid body 2 is closed, and the ring body 3 is smoothly locked to the neck ring 22. The ring body 3 can be easily separated. Furthermore, the ring body 3 and the lid body 2 can be distinguished from each other in appearance, and the unauthorized opening prevention function can be easily grasped. Further, the top plate portion 13 is positioned so as to cover not only the outer periphery of the step portion 24 but also the upper surface of the neck ring 22.

  As shown in FIG. 8, the top plate portion 13 has an abutting portion 17 whose inner peripheral surface side is inclined, and an inclined surface 18 is formed on the inner surface side (lower surface side) between the side wall portion 14. The abutting portion 17 is inclined so as to be positioned on the outer periphery as the lower side, and the upper inner peripheral surface comes into contact with the outer peripheral surface of the stepped portion 24. The inclined surface 18 is inclined so as to be positioned higher on the inner periphery, and the lower surface is in contact with the upper surface of the neck ring 22. The ring body 3 is positioned and held on the stepped portion 24 and the neck ring 22 by the contact of the contact portion 17 and the inclined surface 18, and the ring body 3 is appropriately locked to the neck ring 22. When the cap 1 is excessively tightened due to the inclination of the inclined surface 18 and the notch portion 4, the contact portion between the top plate portion 13 and the neck ring 22 is elastically deformed to prevent the connection portions 10 and 11 from being broken. doing.

  The side wall portion 14 extends downward from the outer peripheral end of the top plate portion 13, and as shown in FIGS. 7 and 8, the outer diameter and inner diameter thereof are larger than the outer diameter of the neck ring 22 and the cylindrical portion 7, It is smaller than the outer diameter of the trunk portion 20b. The side wall portion 14 has a predetermined height in the vertical dimension and is larger than the vertical dimension of the neck ring 22 and is positioned so as to cover the neck ring 22 at the time of closing. The side wall portion 14 at the time of closing covers the curved surface at the outer peripheral end of the neck ring 22 and the outer peripheral surface below the neck ring 22 of the neck portion 21, and has a gap above and below the lower end and the shoulder portion 20b.

  The side wall portion 14 has claws 16a and 16b that are means for preventing unauthorized opening. By engaging the claws 16a and 16b with the lower surface of the neck ring 22, resistance to the opening operation is obtained and unauthorized opening is prevented. Specifically, as shown in FIGS. 4 and 5, a plurality of holes 15 a and 15 b that are formed in the side wall portion 14 so as to open, and a claw 16 a that is inclined in the inner circumferential direction in the holes 15 a and 15 b. 16b. As shown in FIG. 7, the upper portions of the claws 16 a and 16 b elastically contact the lower surface of the neck ring 22, so that the side wall portion 14 is locked to the neck ring 22 and the inclined surface 18 and the claws 16 a and 16 b. And the neck ring 22 is clamped. By this locking and clamping, the ring body 3 can be properly locked to the neck ring 22 while having an unauthorized opening prevention function, and the unauthorized opening prevention function can be appropriately secured.

  As shown in FIGS. 4 and 5, the holes 15 a and 15 b are arranged at a predetermined interval in the circumferential direction of the side wall portion 14. In this example, five holes 15 a and 15 b are formed at approximately equal intervals, for example. The holes 15 a and 15 b are located between the connection parts 10, 10 and 11.

  The claw 16a is formed in a rectangular plate shape that protrudes upward from the lower end of the hole 15a. The claw 16b is formed in a trapezoidal plate shape that protrudes from the lower end of the hole 15b to the upper inner peripheral side, and the protruding tip extends to the adjacent claw 16b side in the circumferential direction. Adjacent claws 16b and 16b jointly exert a strong resistance as a claw larger than the claw 16a during the opening operation to prevent unauthorized opening, while a portion between the holes 15b and 15b of the side wall portion 14 is formed. Damage or excessive deformation of the ring body 3 due to this resistance is prevented.

  As shown in FIG. 5, by rotating the ring body 3 from the closed state engaged with the neck ring 22 in the opening rotation direction S, the claws 16a and 16b elastically contacting the neck ring 22 become resistance of the opening operation. When the cap 1 is further rotated, the ring body 3 is elastically deformed while the first connecting portions 10 and 10 are broken at the breaking portion by the contact resistance of the claws 16a and 16b, and the lid body 2 is rotated upward along the screw thread 23. The cap 1 can be removed from the bottle 20 (opened).

  The unauthorized opening prevention function according to the present embodiment is such that the side wall portion 14 hangs down in the vertical direction due to the presence of the top plate portion 13. Unlike the ring body of the stopper preventing function, the locking by the claws 16a and 16b can be ensured. Furthermore, the neck ring 22 of the bottle 20 can be formed wider than the screw thread 23 by using the cap 1 having the function of preventing unauthorized opening using the top plate portion 13, and this function is ensured. Can do.

  As shown in FIG. 6, after opening the plug, the second connecting portion 11 is broken by moving the ring body 3 with respect to the lid 2 so as to twist the second connecting portion 11 that is not broken by the opening operation. The ring body 3 and the connecting portions 10 and 11 can be separated from the lid body 2 by breaking from the lid body 2. During the opening operation, the upper rear end of the ring body 3 in the opening rotation direction S comes into contact with the protrusion 8 to limit elastic deformation near the upper rear end and twisting of the second connecting portion 11. The second connecting portion 11 can be prevented from being broken by the opening operation.

  In the second embodiment, as shown in FIG. 9, the outer diameter of the neck ring 22 is smaller than that in the first embodiment. The outer diameter of the neck ring 22 is substantially the same as the outer diameter of the lid 2, and the horizontal dimension of the top plate portion 13 of the ring body 3 of the lid 2 is slightly shortened.

  In the third embodiment, as shown in FIG. 10, the top plate portion 13 is not formed with the contact portion 17 and the inclined surface 18. The top plate portion 13 has a plane whose inner peripheral surface is vertical so that the inner side surface 13 a is positioned in the vicinity of the outer periphery of the stepped portion 24. The top plate portion 13 has a horizontal plane so that the lower surface between the top plate portion 13 and the side wall portion 14 is positioned in the vicinity of the upper surface of the neck ring 22. The ring body 3 is positioned and held on the step portion 24 and the neck ring 22 by the arrangement in the vicinity of the inner side surface and the lower surface of the top plate portion 13, and the ring body 3 is appropriately locked to the neck ring 22. When the cap 1 is excessively tightened due to the inclination of the inclined surface 18 and the notch portion 4, the contact portion between the top plate portion 13 and the neck ring 22 is elastically deformed to prevent the connection portions 10 and 11 from being broken. doing.
