  The present invention is a liquid that is attached to the mouth part of the bottle container, and when the lid is opened, the inner plug ring member for preventing dripping is fitted and placed in the opening part of the mouth part of the bottle container. It relates to a cap with a stopper to prevent drool.

  Conventionally, bottle containers for storing medicinal bottle containers, beverage containers, and other liquids are attached to the mouth part of the bottle container, and when a lid opening operation is performed, the liquid is poured into the opening part of the mouth part of the bottle container. There is provided a cap with a dripping-preventing middle stopper that is in a state in which a middle stopper ring member for prevention is fitted and placed.

  That is, as this kind of cap with a dripping-preventing inner cap, Patent Document 1 (Japanese Utility Model Publication No. 6-69163), Patent Document 2 (Japanese Utility Model Publication No. 7-4358), Patent Document 3 (Japanese Utility Model Publication No. 6-27562). No. 2), Patent Literature 4 (Utility Model Registration No. 2509674), Patent Literature 5 (Utility Model Registration No. 2510503), Patent Literature 6 (Utility Model Registration No. 2533413), Patent Literature 7 (Utility Model Registration). No. 3002903), Patent Document 8 (Patent Publication No. 311595), and the like have been proposed.

In this case, as a cap with a dripping-preventing stopper, if Patent Document 3 (Japanese Utility Model Publication No. 6-27562) is described as an example, the structure is as shown in FIGS.
That is, the cap 100 with a dripping-preventing inner cap is provided with a substantially bottomed cylindrical cap main body 102, and is formed so as to project downward from the inner surface of the top plate portion 104 of the cap main body 102. A cylindrical plug stopper 106 is provided.

On the inner periphery of the outer peripheral side wall 108 of the cap main body 102, an inner peripheral screw 116 that is screwed with an outer peripheral screw 114 formed on the outer periphery of the mouth 112 of the bottle container 110 is formed.
The cap main body 102 includes a substantially cylindrical inner plug ring member 118 that is detachably fitted to the outer peripheral portion of the inner plug locking member 106. The inner plug locking member 106 and the inner plug ring member 118 are fitted to each other by a protrusion 120 formed on the outer periphery of the inner plug locking member 106 and an engagement protrusion 122 provided on the inner periphery of the inner plug ring member 118. It is made by fitting with.

A flange portion 124 protruding from the outer peripheral side is formed at the upper end portion of the inner plug ring member 118.
As shown in FIG. 14, the cap 100 with a dripping-preventing inner stopper configured as described above is provided on the inner periphery of the inner stopper ring member 118 and the projection 120 formed on the outer periphery of the inner stopper locking member 106. The inner plug ring member 118 is locked to the outer peripheral portion of the inner plug locking member 106 of the cap body 102 by fitting the engaging protrusion 122.

  In this state, by rotating the cap body 102 in the closing direction, the inner peripheral screw 116 on the inner periphery of the outer peripheral side wall 108 of the cap main body 102 is screwed to the outer peripheral screw 114 on the outer periphery of the mouth 112 of the bottle container 110. By doing so, the cap body 102 is closed on the mouth 112 of the bottle container 110.

  As a result, as shown in FIG. 14, the inner stopper ring member 118 fitted to the outer peripheral portion of the inner stopper locking member 106 of the cap body 102, together with the inner stopper locking member 106, is placed in the mouth 112 of the bottle container 110. Thus, the sealing property of the bottle container 110 is secured by the inner stopper ring member 118.

  When the lid is opened, the cap body 102 is rotated in the opening direction, so that the inner circumference screw 116 on the inner circumference of the outer circumference side wall 108 of the cap body 102 and the outer circumference of the outer circumference of the mouth 112 of the bottle container 110 are displayed. When the screw 114 is released, the cap body 102 is detached from the mouth 112 of the bottle container 110 and the lid is opened.

  At this time, the inner plug ring member 118 and the bottle are larger than the fitting force between the protrusion 120 formed on the outer periphery of the inner plug locking member 106 and the engagement protrusion 122 provided on the inner periphery of the inner plug ring member 118. Since the fitting force with the inner wall of the mouth portion 112 of the container 110 is set to be large, an inner stopper ring member for preventing dripping is formed in the opening portion of the mouth portion 112 of the bottle container 110 when the lid opening operation is performed. It is comprised so that it may be in the state which 118 fits.

  However, in the cap 100 with a dripping-preventing inner stopper configured as described above, whether or not the lid is opened is determined by attaching the cap body 102 to the mouth 112 of the bottle container 110 and closing the lid. For example, the user cannot distinguish.

  Therefore, in such a cap 100 with a dripping-preventing stopper, the liquid contained in the bottle container 110 is a chemical solution that has a problem in that, for example, the period of use is limited and the quality deteriorates due to contamination with foreign matter or contact with air. In beverages and the like, it is impossible to determine whether or not the lid has been opened.

  For this reason, conventionally, sealing with a shrink film or the like is performed in an initial state in which the cap 100 with a dripping-preventing inner stopper is attached to the mouth portion 112 of the bottle container 110. Extra costs and processes are required.

  For this reason, conventionally, a cap with a dripping-preventing inner stopper having a tamper-proof function called tamper evidence (TE) has been disclosed in Patent Document 9 (Japanese Patent Laid-Open No. 2001-58658). The cap 200 with a dripping-preventing inner stopper has a structure as shown in FIGS. 15 and 16.

  That is, the cap 200 with a dripping-preventing plug is provided with a substantially bottomed cylindrical cap main body 202, and is formed in a substantially cylindrical shape so as to project downward from the inner surface of the top plate portion 204 of the cap main body 202. An inner stopper locking member 206 is provided.

On the inner periphery of the outer peripheral side wall 208 of the cap body 202, an inner peripheral screw 216 that is screwed into an outer peripheral screw 214 formed on the outer periphery of the mouth 212 of the bottle container 210 is formed.
Then, the cap portion 207 of the inner plug member 218 is locked (fitted) with the undercut 205 of the cap main body 202, thereby being fitted into the cap main body 202 in a detachable manner. An inner plug member 218 is provided.

At the upper end portion of the inner plug member 218, a flange portion 224 is formed on the outer peripheral side so as to project in a substantially inverted L shape. In addition, the inner plug member 218 is formed with a lid portion 222 that can be cleaved by pulling the pull ring 220 and serves as an opening that constitutes the spout.

  The bottle body is connected to the lower end of the outer peripheral side wall 208 of the cap body 202 via a breakable portion 226 that can be broken when the cap is opened, and is in a state of being fitted and placed on the outer periphery of the mouth portion 212 of the bottle container 210 when the lid is opened. A stop ring member 230 is provided.

A plurality of bottle locking flap pieces 234 are formed at the lower end of the bottle locking ring member 230 so as to be foldable on the inner peripheral side.
The bottle locking flap piece 234 is bent to the outer periphery of the mouth portion 212 of the bottle container 210 by bending the cap 200 with a dripping-preventing inner cap 200 into the mouth portion 212 of the bottle container 210, by bending it to the inner periphery side. It is latched by the mouth flange portion 232 formed to project.

  These bottle locking flap pieces 234 are divided by a substantially rectangular dividing notch 236, and each bottle locking flap piece 234 has a dividing notch 236 at the center of its lower end. A substantially rectangular bending notch 238 having a notch depth smaller than the notch depth is formed.

  As shown in FIG. 16, the cap 200 with a dripping-preventing inner stopper configured as described above is configured by fitting the inner stopper member 218 to the outer peripheral portion of the inner stopper locking member 206 of the cap body 202. The inner plug member 218 and the inner plug locking member 206 are sealed so as not to leak.

  In this state, by rotating the cap body 202 in the closing direction, the inner peripheral screw 216 of the outer peripheral side wall 208 of the cap main body 202 is screwed into the outer peripheral screw 214 of the outer periphery of the mouth 212 of the bottle container 210. By doing so, the cap body 202 is closed to the mouth portion 212 of the bottle container 210.

  As a result, as shown in FIG. 16, the inner stopper member 218 fitted to the outer peripheral portion of the inner stopper locking member 206 of the cap body 202 is put into the mouth 212 of the bottle container 210 together with the inner stopper locking member 206. The sealed state of the bottle container 210 is secured by the inner plug member 218 in the fitted state.

  In this state, as shown in FIG. 16, each of the plurality of bottle locking flap pieces 234 formed at the lower end of the bottle locking ring member 230 is bent toward the inner peripheral side, thereby the bottle container 210. The mouth portion 212 is engaged with a mouth flange portion 232 projecting from the outer periphery of the mouth portion 212.

And when opening the lid, by rotating the cap body 202 in the opening direction,
The cap body 202 is lifted by releasing the screwing of the inner peripheral screw 216 on the inner periphery of the outer peripheral wall 208 of the cap body 202 and the outer peripheral screw 214 on the outer periphery of the mouth 212 of the bottle container 210.

  However, the cap main body 202 is locked to the mouth flange portion 232 formed on the outer periphery of the mouth portion 212 of the bottle container 210 by the bottle retaining flap piece 234 at the lower end of the bottle retaining ring member 230. In this state, the breaking portion 226 formed at the lower end of the outer peripheral side wall 208 of the cap body 202 is broken.

  The cap main body 202 is detached from the mouth 212 of the bottle container 210 and closed, and at the same time, the bottle locking ring member 230 is fitted on the outer periphery of the mouth 212 of the bottle container 210 when the lid is opened. It will be in the state. As a result, it is visually recognized that the cap 200 with a dripping-preventing stopper is opened by a consumer, a patient, etc., and a tamper-proof function called tamper evidence (TE) property is given. Yes.

  At this time, the inner stopper locking member 206 includes a protrusion 237 formed at the lower end of the flange portion 224 protruding in a substantially inverted L shape on the outer peripheral side of the upper end of the inner stopper locking member 206, and the mouth of the bottle container 210. By engaging with a fitting groove 235 formed on the outer periphery of the upper end of the portion 212, the bottle 212 is locked to the mouth portion 212, the bulging portion 240 on the outer periphery of the inner stopper member 218, and the bottle container 210. The bottle 212 is locked to the mouth 212 of the bottle container 210 by fitting with the inner wall of the mouth 212.

  Therefore, the fitting force between the inner stopper member 218 and the mouth portion 212 of the bottle container 210 is set larger than the fitting force between the outer periphery of the inner stopper member 206 and the inner periphery of the inner stopper member 218. Therefore, when the lid opening operation is performed, the inside stopper member 218 for preventing dripping is fitted and placed in the opening of the mouth portion 212 of the bottle container 210.

Then, by pulling on the pull ring 220, the lid portion 222 is cleaved to form an opening that forms a spout, and the liquid stored in the bottle container 210 can be poured.

  However, in the cap 100 with a dripping-preventing inner stopper that does not have a tamper-proof function called a conventional tamper-evidence (TE) property such as Patent Document 3 (Japanese Utility Model Publication No. 6-27562), as described above. It is possible to determine whether the liquid stored in the bottle container 110 has been opened, for example, in liquid medicines, beverages, etc. in which the period of use is limited and foreign matter contamination, quality degradation due to contact with air, etc. is a problem. It becomes a problem.

  For this reason, conventionally, sealing with a shrink film or the like is performed in an initial state in which the cap 100 with a dripping-preventing inner stopper is attached to the mouth portion 112 of the bottle container 110. Extra costs and processes are required.

  Further, in this cap 100 with a dripping-preventing inner stopper, as shown in FIG. 14, the inner stopper ring member 118 is locked to the outer peripheral portion of the inner stopper locking member 106 of the cap body 102. This is achieved by fitting a protrusion 120 formed on the outer periphery of the inner stopper locking member 106 and an engagement protrusion 122 provided on the inner periphery of the inner stopper ring member 118.

  Further, as shown in FIG. 14, the inner plug is fitted by fitting the protrusion 120 formed on the outer periphery of the inner plug locking member 106 with the engaging protrusion 122 provided on the inner periphery of the inner plug ring member 118. Since the ring member 118 is merely locked to the inner plug locking member 106, when this fitting force is weak, when the cap 100 with a dripping prevention inner plug is transported or in the production line The member 118 may fall off the cap body 102.

  Conversely, when the fitting force between the protrusion 120 formed on the outer periphery of the inner stopper locking member 106 and the engaging protrusion 122 provided on the inner periphery of the inner stopper ring member 118 is too strong, the lid opening operation is performed. When this is done, the inner stopper ring member 118 does not come off from the inner stopper engaging member 106, and the inner stopper ring member 118 is opened together with the inner stopper engaging member 106 of the cap body 102, and the mouth of the bottle container 110. There is a possibility that the inside plug ring member 118 for preventing dripping does not fit into the opening of the portion 112.

On the other hand, in the cap 200 with a dripping-preventing inner stopper provided with a falsification preventing function (tamper evidence) disclosed in Patent Document 9 (Japanese Patent Laid-Open No. 2001-58658), the inner stopper member 218 includes a pull ring 220. The lid 222 that can be cleaved by pulling and that serves as an opening that constitutes the spout must be configured, and the configuration becomes complicated.

Further, in order to lock the inner stopper member 218 to the mouth portion 212 of the bottle container 210, a protrusion formed at the lower end of the flange portion 224 that protrudes in a substantially inverted L shape on the outer peripheral side of the upper end of the inner stopper member 218. 237 and the engagement of the fitting groove 235 formed on the outer periphery of the upper end of the mouth part 212 of the bottle container 210, the bottle container 210 having the fitting groove 235 formed in the mouth part 212 of the bottle container 210. It is limited to the application to, and lacks versatility. Further, the inner plug member 218 itself has to be formed with a flange portion 224 and a projection portion 237 that project in a substantially inverted L shape, and has a complicated configuration.

In addition, by pulling the pull ring 220, the lid portion 222 is cleaved to form an opening that constitutes the spout, and it is necessary to pour the liquid contained in the bottle container 210, which requires time and effort. It is.

  Further, in this case as well, as shown in FIG. 16, by locking (fitting) the flange portion 207 of the inner plug member 218 with the undercut 205 of the cap body 202, Since the substantially lid-shaped inner plug member 218 is merely locked to the cap body 202, when this fitting force is weak, the inner plug member is used when the dripping prevention cap 200 is transported or in the production line. 218 may fall off the cap body 202.

  Further, as shown in FIG. 15, the bottle locking flap pieces 234 are divided by a substantially rectangular dividing notch 236, and each bottle locking flap piece 234 has a small notch depth. Only the notch 238 for bending is formed.

  Accordingly, when the bottle locking flap pieces 234 are bent to the inner peripheral side, the bottle locking flap pieces 234 abut against each other, and the bottle locking flap pieces 234 are bent at the notch portions 238 having a small notch depth. Adjacent parts may collide with each other and interfere with the bending operation.

  In view of such a current situation, the present invention eliminates the possibility of the cap stopper ring member falling off from the cap body in the production line when transporting the cap with a dripping-preventing stopper, and when the cap is closed, An object of the present invention is to provide a cap with a dripping-preventing inner stopper that can easily and reliably attach a cap with a dripping-preventing inner stopper to the mouth and can maintain the sealing performance of the inner plug ring member.

  In addition, the present invention can be mounted on a general-purpose bottle container without a complicated configuration, can reliably exhibit a tamper-proof function (tamper evidence), and when the lid is opened, Providing a cap with a dripping-preventing plug that allows the inside plug ring member to be securely fitted and placed in the mouth of the bottle container so that the liquid contained in the bottle container can be poured without causing dripping. The purpose is to do.

  Furthermore, when the use of the bottle container is finished, a cap body, an inner stopper ring member, a bottle locking ring member, and a cap with a dripping prevention inner stopper that can separately collect and collect the bottle container are provided. The purpose is to do.

The present invention was invented in order to achieve the problems and objects in the prior art as described above.

A bottle locking ring member that is connected to the lower end of the outer peripheral side wall of the cap body via a breakable portion that can be broken when the lid is opened, and that is in a state of being fitted to the outer circumference of the mouth portion of the bottle container when the lid is opened; Prepared,
The inner ring member is
A substantially cylindrical inner stopper ring member main body fitted to the outer periphery of the inner stopper locking member and fitted to the opening of the mouth of the bottle container when the lid is closed,
A liquid dripping prevention flange portion that is formed so as to protrude on the outer peripheral side at the upper end portion of the inner plug ring member main body, and has a liquid dripping prevention action;
When the inner plug ring member is mounted on the outer peripheral portion of the inner plug locking member of the cap body, the inner plug ring member prevents the inner plug ring member from falling off and protrudes toward the inner peripheral side of the lower end inner peripheral portion of the inner plug ring member main body. An inner periphery side locking portion formed,
The bottle locking ring member,
A ring locking member main body,
It is formed to be foldable on the inner peripheral side at the lower end of the bottle locking ring member main body, and when the cap with a dripping prevention middle stopper is attached to the mouth of the bottle container, by bending to the inner peripheral side, The bottle container is characterized in that a plurality of bottle locking flap pieces are formed which are locked to a mouth flange portion protrudingly formed on the outer periphery of the mouth portion.

  By comprising in this way, it has the inner peripheral side latching | locking part which protruded and formed in the inner peripheral side at the inner peripheral part of the lower end of the inner stopper ring member main body, When the outer peripheral portion of the stopper member is mounted, the inner peripheral engaging portion is locked to the lower end of the inner plug engaging member.

  Therefore, there is no possibility that the inner stopper ring member will fall off from the cap body when the cap with a stopper for preventing dripping is transported or in the production line. Also, when locking the inner plug ring member to the outer peripheral portion of the inner plug locking member of the cap body, the height of the inner plug ring member is higher than the height of the inner plug locking member. The insertion lock can be easily performed.

  In addition, when the cap with a dripping prevention inner cap is opened, the engagement between the lower end of the inner plug locking member and the inner peripheral side locking portion is easily released, and the inner plug ring member becomes the bottle. As a result, the liquid contained in the bottle container can be poured immediately without causing dripping.

  In addition, when the cap with a dripping-preventing stopper is attached to the mouth of the bottle container, the bottle locking flap piece is bent toward the inner periphery, so that the bottle container is formed to protrude from the outer periphery of the mouth. It is securely locked to the mouth flange.

  As a result, the cap with a dripping-preventing stopper is not likely to fall off from the mouth of the bottle container, so the sealing performance of the inner stopper ring member is reliably maintained between the cap body and the mouth of the bottle container. It is possible.

In addition, when the lid is opened, the bottle locking ring member is locked to the mouth flange portion formed on the bottle container so as to protrude from the outer periphery of the mouth portion. The formed fracture portion will break.

  Then, the cap main body is detached from the mouth of the bottle container and closed, and at the same time, the bottle locking ring member is fitted and placed on the outer periphery of the mouth of the bottle container when the lid is opened. As a result, it is visually recognized that the cap with a dripping-preventing stopper is opened by the consumer, patient, etc., and a tamper-proof function called tamper-evidence (TE) property is surely provided. ing.

Further, when the use of the bottle container is finished, the bottle locking flap piece is bent back to the outer peripheral side so that the bottle container can be engaged with the mouth flange portion that is formed to protrude from the outer periphery of the mouth part. Therefore, the cap main body, the inner stopper ring member, the bottle locking ring member, and the bottle container can be separately collected. An outer peripheral screw formed on the outer periphery of the cap stopper member of the cap main body is deformed when the cap with a dripping-preventing stopper is attached to the mouth of the bottle container. An inner peripheral screw is formed so as to be screwed together.

  With this configuration, when the cap with a dripping-preventing inner cap is attached to the mouth of the bottle container, the inner peripheral screw that is screwed with the outer peripheral screw formed on the outer periphery of the cap stopper member of the cap main body When the inner plug ring member is mounted on the outer peripheral portion of the cap stopper member of the cap body, the outer peripheral screw of the inner stopper member of the cap body is connected to the inner peripheral side of the inner stopper ring member. By screwing the inner peripheral screw of the locking portion, the inner peripheral side locking portion is securely locked to the lower end of the inner plug locking member.

  In addition, when the cap with a stopper that prevents dripping is opened, the cap stopper in the cap body rotates in the opening direction as the cap body rotates in the opening direction. The outer peripheral screw of the inner plug locking member and the inner peripheral screw of the inner peripheral side locking portion of the inner plug ring member are moved in the direction to release the screwing, and the screw coupling is released smoothly. As a result, the inner stopper ring member is securely fitted into the opening of the bottle container, and the liquid stored in the bottle container can be poured immediately without causing dripping.

  In addition, when the cap body is closed again after performing the opening operation, the cap stopper in the cap body rotates in the closing direction by rotating the cap body in the closing direction. The outer peripheral screw of the cap stopper on the inner cap of the cap body and the inner peripheral screw of the inner stopper on the inner stopper ring member are screwed together, and the inner cap ring member ensures the sealing performance of the bottle container. Is done.

  When the lid opening operation is performed again, the cap stopper member of the cap body rotates in the opening direction with the rotation of the cap body in the opening direction, and the stopper stopper of the cap body is locked. The outer peripheral screw of the member and the inner peripheral screw of the inner peripheral side locking portion of the inner plug ring member are smoothly moved without resistance in the direction in which the screwing is released, and the screw connection is released smoothly. As a result, the inner stopper ring member is securely fitted and placed in the mouth portion of the bottle container together with the cap body, and the inner stopper ring member is removed from the mouth portion of the bottle container (so-called “joint out”). Can be prevented.

In addition, the cap with a dripping-preventing inner stopper of the present invention is divided between the plurality of bottle locking flap pieces by a notch for dividing,
Each bottle locking flap piece is formed with a notch for bending having a notch depth smaller than the notch depth of the dividing notch at the lower end thereof.

By configuring in this manner, the bottle locking flap piece can be easily bent to the inner peripheral side, and the bottle locking ring member is bent to the inner peripheral side, and the lower end of the bottle locking ring member is substantially circular. Become a shape.

The cap with a dripping-preventing inner cap according to the present invention is characterized in that a plurality of the folding notch portions are formed at a predetermined interval from each other at the lower end of each bottle locking flap piece.
With this configuration, when the cap with a dripping-preventing inner stopper is attached to the mouth of the bottle container, a plurality of bottle locking flap pieces are bent by folding the bottle locking flap pieces toward the inner peripheral side. As a result, the cap with a dripping-preventing stopper can be evenly and reliably locked to the mouth flange portion protrudingly formed on the outer periphery of the mouth portion of the bottle container.

Moreover, the cap with a dripping-preventing inner stopper of the present invention is characterized in that the bottle locking flap piece has a substantially trapezoidal shape.
With this configuration, when the bottle locking flap pieces are bent toward the inner peripheral side, the bottle locking flap pieces do not collide with each other, and the folding operation is not hindered.

  In addition, the lower end of the bottle locking ring member is likely to be substantially circular with the bottle locking flap piece bent to the inner peripheral side, and the bottle locking flap piece is bent to the inner peripheral side. Easy to hold.

Moreover, the cap with a dripping-preventing inner cap according to the present invention is characterized in that the shape of the dividing notch is substantially trapezoidal.

FIG. 5 is an end view in the V direction of FIG. 4, FIG. 6 is an end view in the VI-VI direction of FIG. 4, and FIG. Fig. 8 is a longitudinal sectional view of an inner stopper ring member of the cap with a dripping prevention inner cap of the present invention, Fig. 8 is an end view in the direction of VIII-VIII of Fig. 7, and Fig. 9 is a dripping prevention inner plug of the present invention. It is a partially broken perspective view of the cap plug ring member of a cap.

  1 to 4, reference numeral 1 generally indicates a cap with a dripping prevention plug according to the present invention. As shown in FIG. 1, the dripping prevention cap 1 with a stopper is attached to a mouth portion 12 having an opening of a bottle container 10 for storing a medicinal bottle container, a beverage container, and other liquids, for example. is there.

  As shown in FIGS. 2 to 4, the cap 1 with a dripping-preventing inner cap includes a substantially bottomed cylindrical cap body 2, and projects downward from the inner surface of the top plate portion 4 of the cap body 2. A substantially cylindrical inner stopper locking member 6 formed so as to be provided is provided.

On the inner periphery of the outer peripheral side wall 8 of the cap body 2, an inner peripheral screw 16 that is screwed with an outer peripheral screw 14 formed on the outer periphery of the mouth 12 of the bottle container 10 is formed.
The cap main body 2 has a substantially lid-shaped inner plug ring member 18 that is detachably fitted to the outer peripheral portion of the inner plug locking member 6 of the cap body 2.

  And it is connected with the lower end of the outer peripheral side wall 8 of the cap main body 2 via the fracture | rupture part 20 which can be fractured at the time of a lid opening, and it is the bottle staff which will be in the state where it fitted to the outer periphery of the opening part 12 of the bottle container 10 at the time of a lid opening. A stop ring member 22 is provided.

  The bottle locking ring member 22 includes a bottle locking ring member main body 24, and a plurality of bottle locking locks formed at the lower end of the bottle locking ring member main body 24 so as to be foldable on the inner peripheral side. A flap piece 26 is formed.

In this embodiment, as shown in FIG. 5, the bottle locking flap piece 26 includes four bottle locking flap pieces 26 along the inner periphery of the lower end of the bottle locking ring member body 24. A substantially trapezoidal cutout portion 30 is formed by being divided at regular intervals.

  This bottle locking flap piece 26 is prevented from dripping by being bent inward on the inner peripheral side when the inner plug ring member 18 is assembled to the outer peripheral portion of the inner plug locking member 6 of the cap body 2 and assembled. When the cap 1 with the inner cap is attached to the mouth portion 12 of the bottle container 10, the cap portion 1 is locked to the mouth flange portion 28 formed to project from the outer periphery of the mouth portion 12 of the bottle container 10.

  These bottle locking flap pieces 26 are divided by a substantially trapezoidal dividing notch 30 and each bottle locking flap piece 26 has a dividing notch 30 at the center of its lower end. A substantially trapezoidal bending notch 32 having a notch depth smaller than the notch depth is formed.

  It should be noted that the number of the bottle locking flap pieces 26 is such that each of the bottle locking flap pieces 26 is bent to the inner peripheral side to project the mouth flange on the outer periphery of the mouth portion 12 of the bottle container 10. Although it is not particularly limited as long as it can be reliably and reliably locked to the portion 28, it is preferable that four or more are preferably formed at the lower end of the bottle locking ring member main body.

  With this configuration, when the bottle locking flap piece 26 is bent toward the inner peripheral side, the bottle locking flap pieces 26 do not collide with each other, and the folding operation is not hindered. ing.

  Further, with this configuration, the bottle locking flap piece 26 can be easily bent toward the inner peripheral side, and the bottle locking ring member 22 can be bent in the state where the bottle locking flap piece 26 is bent toward the inner peripheral side. The bottom end of the bottle tends to be substantially circular, and it is easy to keep the bottle locking flap piece 26 bent to the inner peripheral side.

  In this case, in order to achieve the effect of the bottle locking flap piece 26 described above, as shown in FIG. 4, the bending notch portion 32 with respect to the notch depth L of the dividing notch portion 30. It is desirable that the notch depth 1 is 0.3 to 0.7, preferably 0.4 to 0.5.

  On the other hand, as shown in FIGS. 7 to 9, the inner stopper ring member 18 includes a substantially cylindrical inner stopper ring member main body 34 fitted into the opening of the mouth portion 12 of the bottle container 10 when the lid is closed, The inner plug ring member main body 34 is provided with a dripping prevention flange portion 36 that is formed so as to protrude on the outer peripheral side and has a dripping prevention action.

  Further, the inner plug ring member 18 prevents the inner plug ring member 18 from falling off when the inner plug ring member 18 is attached to the outer peripheral portion of the inner plug locking member 6 of the cap body 2. A plurality of inner peripheral side locking portions 38 are formed on the inner peripheral side of the lower end of the main body so as to project from the inner peripheral side.

  The inner peripheral side locking portion 38 of the inner plug ring member 18 is deformed when the cap 1 with a dripping-preventing inner plug is attached to the mouth 12 of the bottle container 10, An inner peripheral screw 42 that is screwed with an outer peripheral screw 40 formed on the outer periphery of the stop member 6 is formed.

  In this embodiment, the inner cap screw 42 is formed in advance by deforming the cap 1 with a dripping-preventing stopper 1 when the cap 1 is attached to the mouth portion 12 of the bottle container 10. Of course, the inner peripheral screw 42 may not be formed by deformation at the time of mounting.

  By configuring in this way, the inner plug ring member 18 is formed on the outer periphery of the inner stopper locking member 6 of the cap body 2 when the inner stopper ring member 18 is attached to the outer peripheral portion of the inner stopper locking member 6 of the cap body 2. Since the inner peripheral screw 42 that is screwed with the outer peripheral screw 40 is formed, when the inner plug ring member 18 is attached to the outer peripheral portion of the inner plug locking member 6 of the cap main body 2, the inner plug locking of the cap main body 2 is performed. By screwing the inner peripheral screw 42 of the inner peripheral side locking portion 38 of the inner plug ring member 18 into the outer peripheral screw 40 of the member 6, the inner peripheral side locking portion 38 is engaged with the lower end of the inner plug locking member 6. Is securely locked.

In addition, when the cap 1 with the dripping prevention inner cap is opened, the cap stopper 2 in the cap body 2 rotates in the opening direction as the cap body 2 rotates in the opening direction. Then, the outer peripheral screw 40 of the inner plug locking member 6 of the cap body 2 and the inner peripheral screw 42 of the inner peripheral side locking portion 38 of the inner plug ring member 18 are moved in the direction in which the screwing is released, and the screw coupling is performed. It is released smoothly. As a result, the inner stopper ring member 18 is securely fitted and placed in the mouth portion 12 of the bottle container 10, and the liquid stored in the bottle container 10 can be poured immediately without causing dripping.

  Further, when the cap body 2 is closed again after performing the lid opening operation, the cap stopper 2 in the cap body 2 is moved in the closing direction by rotating the cap body 2 in the closing direction. By rotating, the outer peripheral screw 40 of the inner stopper locking member 6 of the cap body 2 and the inner peripheral screw 42 of the inner peripheral locking portion 38 of the inner stopper ring member 18 are screwed together, and the inner stopper ring member 18 Thus, the sealing performance of the bottle container 10 is ensured.

  When the lid opening operation is performed again, the cap stopper 2 in the cap body 2 rotates in the opening direction as the cap body 2 rotates in the opening direction. The outer peripheral screw 40 of the inner plug locking member 6 and the inner peripheral screw 42 of the inner peripheral side locking portion 38 of the inner plug ring member 18 are smoothly moved without resistance in the direction in which the screwing is released, and the screw connection is smooth. Is released. As a result, the inner stopper ring member 18 is in a state of being securely fitted to the mouth portion 12 of the bottle container 10 together with the cap body 2, and the inner stopper ring member 18 is detached from the mouth portion 12 of the bottle container 10 ( So-called “join-off” can be prevented.

  In this case, the number of the inner peripheral side locking portions 38 is not particularly limited, but in consideration of the effect of the inner peripheral side locking portions 38, preferably, as in this embodiment, As shown in FIG. 8, it is desirable to form four pieces at regular intervals in the circumferential direction of the lower end portion of the inner plug ring member 18.

  As shown in FIGS. 2 and 3, the cap 1 with a dripping-preventing inner stopper configured in this manner is provided on the outer peripheral screw 40 of the inner stopper locking member 6 of the cap main body 2 with the inner plug ring member 18. The inner plug ring member 18 is locked to the inner plug locking member 6 by screwing the inner peripheral screw 42 of the peripheral locking portion 38.

  In this state, by rotating the cap body 2 in the closing direction, the inner peripheral screw 16 on the inner periphery of the outer peripheral side wall 8 of the cap main body 2 is screwed to the outer peripheral screw 14 on the outer periphery of the mouth 12 of the bottle container 10. By doing so, the cap body 2 is closed to the mouth 12 of the bottle container 10.

  As a result, as shown in FIG. 2, the inner stopper ring member 18 fitted to the outer peripheral portion of the inner stopper locking member 6 of the cap body 2 is brought into the mouth 12 of the bottle container 10 together with the inner stopper locking member 6. The sealing property of the bottle container 10 is ensured by the inner stopper ring member 18.

In this state, as shown in FIG. 2, each of the bottle locking flap pieces 26 formed at the lower end of the bottle locking ring member 22 is bent toward the inner peripheral side, whereby the bottle container 10. It is locked to the mouth flange portion 28 formed to project from the outer periphery of the mouth portion 12.

  At this time, the bottle locking flap pieces 26 are divided by a substantially trapezoidal dividing notch 30 and each bottle locking flap piece 26 has a dividing portion at the center of its lower end. A substantially trapezoidal bending notch 32 having a notch depth smaller than the notch depth of the notch 30 is formed.

  Accordingly, when the bottle locking flap piece 26 is bent toward the inner peripheral side, the bottle locking flap pieces 26 do not come into contact with each other and do not interfere with the bending operation.

  Further, the bottle locking flap piece 26 can be easily bent to the inner peripheral side, and the lower end of the bottle locking ring member 22 becomes substantially circular in a state where the bottle locking flap piece 26 is bent to the inner peripheral side. In addition, it is easy to maintain the state where the bottle locking flap piece 26 is bent toward the inner peripheral side.

  When the cap is opened, the cap main body 2 is rotated in the direction of the cap opening, so that the inner peripheral screw 16 on the inner periphery of the outer peripheral side wall 8 of the cap main body 2 and the outer periphery of the outer periphery of the mouth 12 of the bottle container 10 are displayed. When the screw 14 is released, the cap body 2 is raised.

  However, the cap main body 2 is locked to the mouth flange portion 28 formed on the outer periphery of the mouth portion 12 of the bottle container 10 by the bottle retaining flap piece 26 at the lower end of the bottle retaining ring member 22. In this state, the breaking portion 20 formed at the lower end of the outer peripheral side wall 8 of the cap body 2 is broken.

  When the cap body 2 is removed from the mouth portion 12 of the bottle container 10 and closed, and at the same time the cap 1 with a dripping-preventing middle stopper is opened, the cap body 2 opens in the direction of opening. With the rotation of the cap body 2, the cap stopper 2 of the cap body 2 rotates in the opening direction, and the outer peripheral screw 40 of the cap stopper 2 of the cap body 2 and the inner peripheral side of the cap stopper member 18. The inner peripheral screw 42 of the locking portion 38 is moved in the direction in which the screwing is released, and the screw connection is released smoothly.

  As a result, the inner stopper ring member 18 is securely fitted and placed in the mouth portion 12 of the bottle container 10, and the liquid stored in the bottle container 10 can be poured immediately without causing dripping.

  Therefore, when the bottle locking ring member 22 is opened, the bottle locking ring member 22 is fitted and placed on the outer periphery of the mouth 12 of the bottle container 10. It is visually recognized that the lid is covered, and a tamper-proof function called tamper evidence (TE) property is given.

At this time, the inner stopper locking member 6 is locked to the mouth 12 of the bottle container 10 by fitting with the inner periphery of the mouth 12 of the bottle container 10.
In this case, the inner plug ring member is more than the screw release force between the outer peripheral screw 40 on the outer periphery of the inner plug locking member 6 and the inner peripheral screw 42 of the inner peripheral side locking portion 38 of the inner plug ring member 18. 18 and the mouth part 12 of the bottle container 10 are set to be large, so that when the lid is opened, an inner stopper for preventing dripping is formed in the opening part of the mouth part 12 of the bottle container 10. The ring member 18 is configured to be in a state where the ring member 18 is fitted.

As shown in FIG. 4, the lower end of the outer peripheral side wall 8 of the cap body 2 and the lower end of the outer peripheral side wall 8 of the cap main body 2 are respectively provided at the lower end of the outer peripheral side wall 8 of the cap body 2 and the upper end portion of the bottle locking ring member 22. Guide members 48 and 50 having tapered surfaces 44 and 46 that are complementary to each other are formed to guide the bottle locking ring member 22 and the upper end portion of the bottle locking ring member 22 apart from each other.

  With this configuration, when the lid is opened (in the direction of arrow A in FIG. 4), the lower end of the outer peripheral side wall 8 of the cap body 2 and the bottle member are fixed by the complementary tapered surfaces 44 and 46 of the guide members 48 and 50. Since the upper end portion of the stop ring member 22 is guided in a direction away from each other, the rupture portion 20 formed at the lower end of the outer peripheral side wall 8 of the cap body 2 breaks uniformly and without requiring force. The bottle locking ring member 22 is configured to be fitted and placed on the outer periphery of the mouth portion 12 of the bottle container 10 when the lid is opened.

  The tapered surfaces 44, 46 opposite to the tapered surfaces 44, 46 of the guide members 48, 50 are brought into contact with each other when the cap body 2 is closed once the cap body 2 is opened, thereby preventing bridge breakage. Is configured to act as a stopper for.

  FIG. 10 is a partially broken perspective view of the inner plug ring member similar to FIG. 9 of the second embodiment of the cap with a dripping prevention plug according to the present invention. FIG. 11 shows the cap with a dripping prevention plug according to the present invention. FIG. 12 is a partially enlarged longitudinal sectional view showing a mounting state of a cap with a dripping-preventing inner stopper similar to FIG. 2 of the second embodiment, FIG. 12 is a second embodiment of the cap with a dripping-preventing inner plug of the present invention. It is a longitudinal cross-sectional view which shows the state before mounting | wearing with the opening part of the bottle container of the cap main body similar to FIG.

The cap 1 with a dripping prevention inner stopper of the second embodiment has basically the same configuration as the cap 1 with a dripping prevention middle stopper of the first embodiment shown in FIGS. The same reference numerals are assigned to the constituent members, and detailed description thereof is omitted.
Also, the cap 1 with a dripping-preventing inner stopper of the second embodiment is basically the same in usage as the cap 1 with a dripping-preventing inner stopper of the first embodiment shown in FIGS. Therefore, detailed description thereof will be omitted, and only the difference will be described below.

  That is, in the cap 1 with a dripping-preventing inner stopper of the first embodiment shown in FIGS. 1 to 9, the inner stopper engagement member 38 of the inner stopper ring member 18 has an inner stopper engagement member of the cap body 2. 6, the inner peripheral screw 42 that is screwed with the outer peripheral screw 40 is formed. However, in the cap 1 with a dripping-preventing inner stopper of the second embodiment, as shown in FIG. The side locking portion 38 is not provided with the inner peripheral screw 42.

  Further, as shown in FIG. 11, the height of the inner plug ring member 18 is made higher than the length of the lower end of the inner plug locking member 6, and the inner peripheral side engagement is connected to the lower end of the inner plug locking member 6. The upper end of the stop portion 38 is configured to be fitted by its flexibility.

  With this configuration, when the inner plug ring member 18 is locked to the outer peripheral portion of the inner plug locking member 6 of the cap body 2, the inner plug ring member is higher than the height of the inner plug locking member 6. Since the height of 18 is high, the insertion locking can be easily performed using a finger or the like.

  Moreover, the cap 1 with a dripping-preventing inner stopper of the second embodiment is provided above the inner peripheral side locking portion 38 on the inner peripheral surface of the inner plug ring member 18, above the inner stopper locking member 6 of the cap body 2. The inner periphery fitting protrusion 56 which fits with the outer periphery screw 40 of the outer periphery is formed.

With this configuration, when the cap 1 with a dripping prevention middle cap is opened, the cap stopper 2 in the cap main body 2 is moved as the cap main body 2 rises in the opening direction. Ascending in the opening direction, the outer peripheral screw 40 of the inner stopper locking member 6 of the cap body 2 and the inner peripheral engagement protrusion 56 above the inner peripheral locking portion 38 of the inner stopper ring member 18 are fitted. The inner ring member 18 is released by the flexibility. As a result, it is possible to reliably pour the liquid stored in the bottle container 10 without causing any dripping.

Further, when the cap body 2 is closed again after the lid opening operation, the cap stopper 2 of the cap body 2 is moved in the closing direction by lowering the cap body 2 in the closing direction. lowered to, the outer peripheral screw 40 of the inside plug locking member 6 of the cap body 2, and the upper inner peripheral fitting projection 56 on the inner circumferential side locking portion 38 of the inner plug ring member 18 is fitted, medium The sealing performance of the bottle container 10 is reliably ensured by the stopper ring member 18.
