Description

  The present invention relates to a container lid attached to a container, and more particularly to a container lid that can be prevented from being arbitrarily opened.

  In general, containers that store extremely toxic drugs, containers that store detergents, containers that store general household medicines, etc. are obliged to be fitted with a child protection lid so that children cannot easily open the lid. It is a tendency to.

  FIG. 1 is a cross-sectional view illustrating a child protection lid according to the prior art.

  The lid for protecting children according to the prior art is disposed outside the inner lid 154 and an inner lid 154 that is formed in the container 150 and is attached to a container inlet 152 from which the contents stored in the container 150 are discharged. The outer lid 156 is moved up and down within a certain range, and the outer lid 156 is formed between the inner lid 154 and the outer lid 156 and is pushed only when the outer lid 156 is pushed downward. And a rotational force transmission unit 160 that transmits the rotational force of 156 to the internal lid 154 to rotate the internal lid 154.

  A sealing member 170 for protecting the contents stored in the container 150 is bonded to the upper surface of the container inlet 152 of the container 150.

  A female screw portion 174 is formed below the inner lid 154 so as to be screwed into a male screw portion 172 formed on the outer circumferential surface of the container inlet 152, and the inner lid 154 is formed on the inner peripheral surface at the lower end of the outer lid 156. A locking protrusion 178 that prevents the outer cover 156 from detaching from the outer cover 156 is protruded.

  The rotational force transmission unit 160 includes a plurality of first locking protrusions 164 that are radially arranged on the outer upper surface of the inner lid 154 with a predetermined interval and project upward by a predetermined width, and the outer lid. A plurality of second locking projections 166 which are arranged on the inner upper surface of 156 in a radial manner with a predetermined interval and project downward by a predetermined width and are locked to the first locking projections 164; Composed.

  The lid for protecting children according to the prior art configured as described above has the outer lid 156 that rotates idly on the outer peripheral surface of the inner lid 154 with the inner lid 154 attached to the container inlet 152. Even if is turned, the rotational force is not transmitted to the inner lid 154 and the child cannot easily open it.

  When the lid is opened, when the outer lid 156 is pushed downward, a plurality of second engagements formed on the outer lid 156 are formed in a space between the plurality of first locking projections 164 formed on the inner lid 154. When the external projection 166 is inserted and meshed with each other and the external lid 156 is rotated in such a state, the rotational force is transmitted to the internal lid 154 and the internal lid 154 is also rotated while the internal lid 154 is rotated. Separated from the container inlet 152.

  After the lid is separated from the container inlet 152, the sealing member 170 sealed at the container inlet 152 is removed by hand, or removed using a separate tool such as a knife, and the contents stored in the container 150 are removed. Is discharged through the container inlet 152.

  However, the above-described container lid for protecting children according to the prior art can be removed by manually removing the sealing member 170 bonded and sealed to the container inlet 152 after the container lid is separated from the container 150. However, since it should be removed using a separate tool such as a knife, there is an inconvenience that it is inconvenient to use.

  In particular, when removing the sealing member 170 by hand, the adhesive force between the edge of the sealing member 170 and the container inlet 152 is strong, and the sealing member 170 is not easily separated from the edge. Inconveniently, a hand touches the container inlet 152 at that time, which may cause sanitary problems.

  Furthermore, the child protection lid according to the prior art has a plurality of locking projections 164 and 166 formed on the upper side of the inner lid 154 and the outer lid 156, respectively, and does not have a structure for pushing the outer lid 156 upward. 156 is lowered downward by its own weight, so that the second locking projection 166 of the outer lid 156 and the first locking projection 164 of the inner lid 154 are locked with each other, and the child opens the lid. There was a problem that occurred frequently.

  On the other hand, the child protection lid according to the prior art has a structure in which the child cannot open the lid of the container. However, even if the lid is arbitrarily opened, it cannot be confirmed whether or not the lid is open. There was a problem.

  Also, if you can open the lid of the container arbitrarily, for example, do not expect good suppliers or consumers to inject and sell fake contents instead of high-priced contents such as Western liquor It had the problem of incurring damage.

  An object of the present invention is to provide a container lid that can confirm whether or not the container lid can be opened when the container lid is arbitrarily opened in order to solve the above-described problems of the prior art.

  Another object of the present invention is to provide a lid of a container that can be opened or prevented by arbitrarily opening it so as to leave an opening trace once attached to the container.

  The present invention has been made in order to achieve the above-described object of the present invention. The present invention includes an inner lid attached to a container inlet of a container, and an outer peripheral surface of the inner lid with respect to the inner lid. An external lid arranged so as to be able to rotate idly, and formed between the internal lid and the external lid, and the rotational force in the opening direction of the external lid is applied only when the external lid is moved downward by a predetermined force or more. A part of the upper surface of the outer lid supported by a rotational force transmitting portion for transmitting to the inner lid, and a spacer provided between the outer lid and the inner lid to maintain a distance between the outer lid and the inner lid. While being formed, the outer lid is detachably provided, and is formed between the inner lid and the outer lid, and the outer lid is moved downward by a predetermined force or more to rotate the outer lid in the opening direction. Even if the outer lid is transmitted to the inner lid, the outer lid On the other hand, after being separated from the external lid so that only the idling can be performed in the opening direction, the external lid is rotated when the external lid is moved downward by a predetermined force or more by the rotational force transmitting portion. A container lid is disclosed that includes a protective plate that transmits force to the inner lid.

  Furthermore, the present invention includes an inner lid attached to the container inlet of the container, an outer lid disposed on the outer peripheral surface of the inner lid so as to be able to idle with respect to the inner lid, and between the inner lid and the outer lid. A rotational force transmitting portion that transmits rotational force in the opening direction of the external lid to the internal lid only when the external lid is moved downward with a predetermined force or more, and the external lid and the internal lid Even if the outer lid is moved downward by a predetermined force or more and the rotational force in the opening direction of the outer lid is transmitted to the inner lid, the outer lid is open to the inner lid. A container lid is disclosed that includes a spacer that maintains the distance between the outer lid and the inner lid so that only idle rotation is possible.

  The technical gist of the present invention is that a container lid is constituted by an inner lid coupled to the container and an outer lid coupled to the inner lid and transmitting a rotational force to the inner lid by meshing, and the container lid is attached to the container. Thereafter, a spacer is provided to maintain a distance from the inner lid so that the outer lid is idly rotated in the opening direction.

  Hereinafter, the container lid according to the present invention will be described in detail with reference to the accompanying drawings and examples.

  The container lid according to the first embodiment of the present invention includes an inner lid 14 attached to a container inlet 12 through which contents stored in the container 10 are discharged to the outside, and an inner lid 14 on the outer peripheral surface of the inner lid 14. The external lid 16 is arranged so as to be able to rotate idly, and is formed between the internal lid 14 and the external lid 16, and the rotational force of the external lid 16 is applied only when the external lid 16 is moved downward by a predetermined force or more. A rotational force transmitting portion 18 that transmits to the lid 14 and a spacer 15 that is provided between the outer lid 16 and the inner lid 14 and maintains the distance between the outer lid 16 and the inner lid 14. After being separated from the external lid 16 so as to be detachable from the external lid 16 so as to be separable from the external lid 16 so as to be separable from the external lid 16. 18 to move the external lid 16 to a predetermined force or less. In is configured to include a, a protective plate 13 for transmitting the internal cap 14 a rotational force of the outer lid 16 when moved to the lower direction.

  The container 10 can store various contents such as contents that are dangerous to children, such as highly toxic drugs, detergents, and general household medicines, purified contents, and powder contents.

  A sealing member 20 is attached to the container inlet 12 from which the contents are discharged to the outside, and the container inlet 12 is sealed to protect the contents stored in the container 10. Here, the sealing member 20 is preferably formed of a paper material or a material that can be easily removed with a knife or the like, such as an aluminum foil plate material.

  The inner lid 14 has a cylindrical shape with an open upper end and a lower end, and a female thread portion 26 that is screwed into a male thread portion 24 formed on the outer peripheral surface of the container inlet 12 is formed on the lower inner peripheral surface. A close contact portion 28 is formed on the upper inner peripheral surface of the portion 26 so as to protrude toward the inner peripheral edge so that the upper end of the container inlet 12 is in close contact therewith.

  Further, a detachment preventing protrusion 11 is formed on the outer peripheral surface of the lower end of the inner lid 14 so as to protrude from the outer lid 16. At this time, an external detachment preventing protrusion 16b is formed on the inner peripheral surface of the lower end of the outer cover 16 instead of the detachment preventing protrusion 14a for preventing the detachment of the inner cover 14 or formed together.

  The outer lid 16 has a cylindrical shape that is inserted into the inner lid 14 so as to be movable in the vertical direction to the outside, and has an upper end and a lower end opened. The uneven protrusion 16c is formed.

  The rotational force transmission unit 18 includes one or more first keys 40 formed on the outer surface of the inner lid 14 in the circumferential direction, and formed on the inner surface of the outer lid 16 in the circumferential direction. One or more second keys 42 that mesh with the first key 40 and transmit the rotational force in the opening direction of the outer lid 16 to the inner lid 14 only when pressed with a predetermined force or more.

  The first key 40 can have various shapes such as being arranged in a plurality along the circumferential direction at equal intervals, and the second key 42 of the outer lid 16 is engaged in the closing direction of the inner lid 14. A protrusion is formed so as to be stopped, and an inclined surface is formed so as to get over even if the second key 42 of the outer lid 16 contacts by pressing in the opening direction of the inner lid 14.

  On the other hand, the second key can have various shapes such as a plurality of second keys arranged at equal intervals along the circumferential direction, and the protrusion of the first key 40 is locked in the closing direction of the outer lid 16. Thus, the protrusion is formed, and the inclined surface is formed so as to get over even when the inclined surface of the first key 40 contacts the opening direction of the external lid 16.

  Here, the first key 40 and the second key 42 may be any structure that engages with each other when the outer lid 16 is pressed, and may be formed anywhere on the outer surface of the inner lid 14 and the inner surface of the outer lid 16. Can do.

  On the other hand, since the first key 40 and the second key 42 need to maintain a constant distance from each other, the outer lid 16 is supported by the upper surface of the inner lid 14 and the state where the outer lid 16 has moved upward from the inner lid 14 is maintained. An elastic member (not shown) is formed.

  Here, unlike the spacer that enables only idling in the opening direction, the elastic member is formed in a thin film shape that generates a predetermined elastic force while flexing itself, and its end is the upper surface of the inner lid 14. The elastic force which is supported on the outer cover 16 and moves upward is applied to the outer lid 16 to maintain the state where the outer lid 16 has moved upward.

  When the outer lid 16 is pushed downward, the elastic member is elastically deformed and the external lid 16 is moved downward. When the force acting on the external lid 16 is removed, the elastic member itself is elastic. The external lid 16 is moved upward by the force to return to the original position.

  In such a rotational force transmitting portion 18, when the outer lid 16 is not pressed with a predetermined force, the outer lid 16 is not completely pressed because the elastic force of the elastic member acts on the outer lid 16. Even if the first key 40 and the second key 42 of the outer lid 16 are not completely inserted into each other and the outer lid 16 is rotated, the second key 42 gets over the inclined surface of the first key 40, so that the outer lid The rotational force of 16 is not transmitted to the inner lid 14 to prevent the container lid from being opened.

  The protective plate 13 is formed in a circular plate shape having a predetermined interval on the upper inner peripheral surface of the outer lid 16, and is between the outer peripheral surface of the protective plate 13 and the upper inner peripheral surface of the outer lid 16. When the protection plate 13 is fixed to the external lid 16 and the protection plate 13 moves downward, the connection portions are interconnected by a plurality of bridges 17 that are cut. Here, in addition to the bridge 17, the protective plate 13 and the external lid 16 may be formed with a cut groove so as to be easily separated.

  On the other hand, the protective plate 13 is formed with a recess 16a in the external lid 16 so that the protective plate 13 is exposed in the radial direction so that the user can easily separate from the external lid 16. At this time, as shown in FIG. 4, the protective plate 13 may be formed to further protrude in the radial direction from the portion exposed in the radial direction.

  Further, the protective plate 13 may be configured to be broken into a plurality of pieces so that the separation trace remains when the user separates from the external lid 16, or to be discolored when deformed. it can.

  The spacer 15 keeps the distance between the inner lid 14 and the outer lid 16 constant so that the first key 40 of the inner lid 14 and the second key 42 of the outer lid 16 can be engaged even if a force is applied to the outer lid 16. Configured as follows.

  The spacer 15 can have any configuration as long as it supports the bottom surface of the protection plate 13 and maintains a constant distance from the outer lid 16, and is formed to protrude from the bottom surface of the protection plate 13 or the upper side surface of the inner lid 14. The

  The spacer 15 can have various configurations such as one or more pillars formed to protrude from the bottom surface of the protective plate 13 or the upper side surface of the inner lid 14. Here, in addition to the pillar, the spacer 15 is formed on an annular ring, a plate or the like as in the third embodiment described later, or the lower end of the inner lid 14 or the outer lid 16 as in the fourth embodiment. It can be configured in various ways, such as in a skirt provided on the skirt.

  On the other hand, in the container lid according to the present invention, when the protective plate 13 supported by the spacer 15 is provided, the outer lid 16 can only be idly rotated with respect to the inner lid 14. In the closing direction, a configuration for transmitting the rotational force, that is, a configuration of the reverse rotation transmission unit is necessary.

  The reverse rotational force transmission unit includes a first inclined protrusion 34 formed on the outer peripheral surface of the inner lid 14 so as to form an inclined surface 34a in the opening direction and a protrusion 34b in the closing direction, and a first inclined An inclined surface 36a is formed in the opening direction corresponding to the protrusion 34, and the outer lid 16 idly rotates with respect to the inner lid 14 over the inclined surface 34a of the first inclined protrusion 34, and a protrusion 36b is formed in the closing direction. Then, the second inclined protrusion 36 formed on the inner peripheral surface of the outer lid 16 is engaged with the protrusion of the first inclined protrusion 36 and the rotational force in the closing direction of the outer lid 16 is transmitted to the inner lid 14. And comprising.

  By the reverse rotation transmission portion constituted by the first inclined protrusion 34 and the second inclined protrusion 36 as described above, the rotational force of the outer lid 16 is transmitted to the inner lid 14 in the closing direction while being able to idle in the opening direction. In this manner, the container lid can be attached to the container 10.

  On the other hand, as another example of the reverse rotation transmission unit, the shape and height of the first key 40 and the second key 42 can be adjusted.

  In other words, the reverse rotation transmission unit is configured such that a protrusion is formed so that the second key 42 of the outer lid 16 is locked to the first key 40 in the closing direction of the inner lid 14, and the opening direction of the inner lid 14. It can be realized by forming an inclined surface so as to get over when the second key 42 of the outer lid 16 comes into contact therewith. At this time, the second key 42 is formed with a protrusion so that the protrusion of the second key 42 is locked in the closing direction of the outer lid 16, and the inclined surface of the second key 42 is in the opening direction of the outer lid 16. An inclined surface is formed so as to overcome the contact.

  In addition, the first key 40 may be configured to include a first inclined portion 51 that constitutes the rotational force transmitting portion 18 together with the second key 42 and a second inclined portion 52 that is higher than the first inclined portion 51.

  The first inclined portion 51 is configured so that the rotational force of the external lid 16 is transmitted to the internal lid 14 only when meshed with the second key 42 and applies a force equal to or greater than a predetermined force to the external lid 16. An inclined surface 51a is formed, and a protrusion 51b is formed in the closing direction.

  In the second inclined portion 52, the rotational force of the external lid 16 is transmitted to the internal lid 14 only in the closing direction with the outer lid 16 positioned on the upper side by the spacer 15, and the external lid 16 rotates idly in the opening direction. In the opening direction, an inclined surface 52a having a height higher than that of the inclined surface 51a of the first inclined portion 51 is formed, and a protrusion 52b is formed in the closing direction. At this time, the surfaces of the inclined surfaces 51a and 52a can be flat or curved.

  The second key 42 may include a first key portion 53 and a second key portion 54 corresponding to the first inclined portion 51 and the second inclined portion 52, respectively. Here, the second key portion 54 forms an inclined surface in the opening direction.

  Further, the first key portion 53 and the second key portion 54 prevent interference with the inclined surfaces 51a and 52a of the first inclined portion 51 and the second inclined portion 52 as shown in FIG. Therefore, the height from the bottom surface of the external lid 16 can be configured differently. That is, the height of the first key portion 53 corresponding to the first inclined portion 51 can be formed higher than the height of the second key portion 52 corresponding to the second inclined portion 52.

  At this time, the first inclined portion 51 and the first key portion 53 are not overlapped with the spacer 15 provided, and the second inclined portion 52 is formed so as to partially overlap the second key portion 52. When the outer lid 16 rotates in the closing direction, the second key portion 52 is locked to the protrusion 52b of the second inclined portion 52, and the rotational force of the outer lid 16 is transmitted to the inner lid.

  Further, the first key portion 53 and the second key portion 54 are configured to have a phase difference around the lid, as shown in FIG. 7c.

  Hereinafter, the operation of the container lid according to the first embodiment of the present invention will be described in detail.

  First, when the container lid according to the present invention is attached to the container, as shown in FIGS. 4 and 10, the inner lid 14 and the outer lid 16 maintain a constant distance by the spacer 15, so that force is applied to the outer lid 16. In addition, the first key 40 and the second key 42 cannot be engaged with each other. Therefore, the outer lid 16 cannot transmit rotational force to the inner lid 14 in the opening direction, and can only perform idling. . Here, of course, it is possible to transmit the rotational force of the external lid 16 to the internal lid 14 by the configuration of the reverse rotation transmission portion, so that it can be attached to the container.

  On the other hand, when the container lid is to be separated from the container 10, the user separates the protective plate 13 from the external lid 16.

  When the protective plate 13 is separated from the external lid 16, the spacer 15 is removed and the external lid 16 is lowered downward as shown in FIGS. After the external lid 16 is lowered in this way, when the user rotates the external lid 16 in the opening direction without applying a predetermined force downward, the second key 42 of the external lid 16 is the first key 40. Move to the inclined surface side.

  Then, as shown in FIG. 9, the second key 42 of the outer lid 16 gets over the inclined surface of the first key 40, so that even after the outer lid 16 is lowered with the protective plate 13 removed, the outer lid 16 Rotates idly with respect to the inner lid 14.

  On the other hand, when the user applies a predetermined force to the outer lid 16 downward, as shown in FIG. 13, the first key 40 and the second key 42 are engaged, and the outer lid 16 is opened. , The rotational force of the outer lid 16 is transmitted to the inner lid 14, and the inner lid 14 rotates and is separated from the container inlet 12.

  Meanwhile, the operation process when the first key 40 has the structure shown in FIGS. 7 and 8 will be described as follows.

  First, before the protection plate 13 is removed, as shown in FIG. 14, the outer lid 16 is lifted upward by the spacer 15, and when the outer lid 16 is rotated in the opening direction, the second key 42 gets over the inclined surface 52 a of the second inclined portion 52. At this time, when the outer lid 16 is rotated in the closing direction, as shown in FIG. 15, the second key 42, that is, the second key portion 54 of the second key 42 is applied to the protrusion 52 b of the second inclined portion 52. The rotational force of the outer lid 16 is transmitted to the inner lid 14 by being locked.

  On the other hand, after the protection plate 13 is removed, the external lid 16 partially moves downward to reach the state shown in FIG.

  At this time, if the user rotates the external lid 16 in the open direction without applying a force downward, the second key 42, that is, the first key portion 53 and the second key portion 54 of the second key 42. Is over the inclined surfaces 51a and 52a of the first inclined portion 51 and the second inclined portion 52 of the first key 40, and rotates idly in the opening direction.

  Then, when the user applies a downward force to the outer lid 16 to rotate it in the opening direction, the second key 42, that is, the first key portion 53 and the second key portion 54 of the second key 42 are shown in FIG. As shown in FIG. 2, the container lid is separated from the container 10 because the rotational force of the outer lid 16 is transmitted to the inner lid 14 by meshing with the first inclined portion 51 and the second inclined portion 52 of the first key 40. .

  On the other hand, the container lid according to the present invention can have various functions on the inner lid or the outer lid, for example, the inner lid has a sealing member removing unit that removes the sealing member and accommodates it inside.

  Hereinafter, the container lid according to the second embodiment of the present invention is formed in the inner lid 14 in the configuration of the container lid according to the first embodiment, and is sealed to the container inlet 12 when the inner lid 14 is separated from the container inlet 12. A sealing member removing unit 22 for removing the sealing member 20 to be removed and storing the removed sealing member 20 in the inner lid 14 is additionally included.

  Here, the container lid according to the second embodiment of the present invention has the same configuration as that of the first embodiment except that the sealing member removing unit 22 is additionally provided. Reference numerals are assigned and detailed description is omitted.

  The sealing member removing unit 22 is arranged inside the inner lid 14 so as to be movable in the vertical direction, and is pressed by the user, and is formed on the lower edge of the pressing plate 24 in the circumferential direction so as to be pressed. Is pushed through the sealing member 20 and the lid is rotated, the cutter 26 that cuts the sealing member 20, and the sealing member 20 that protrudes downwardly on the lower surface of the pressing plate 24 and is cut by the cutter 26 are placed inside the main body 16. A guide 28 is connected between the outer peripheral surface of the pressing plate 24 and the inner peripheral surface of the inner lid 14 so that the pressing plate 24 can move in the vertical direction. The connecting portion 30 supports the position where the pressing plate 24 is moved by the elastic force itself.

  The pressing plate 24 is formed in a disc shape having a diameter smaller than the inner diameter of the inner lid 14.

  The cutter 26 is configured to cut the sealing member 20 by the rotation of the inner lid 14, and as illustrated, a plurality of support portions 26a formed at equal intervals on the lower surface edge of the pressing plate 24. And a first cutting part 26b formed so as to be sharp at the lower end of the support part 26a and protruding through the sealing member 20 while moving downward when the pressing plate 24 is pressed, and at least one of both side surfaces of the support part 60 On the other hand, a second cutting portion 26c formed on the side surface and configured to cut the sealing member 20 in a circular shape while rotating while being in contact with the inner peripheral surface of the container inlet 12 when the inner lid 14 rotates.

  As shown in the drawing, the locking portion 28 is formed on the lower surface of the pressing plate 24 by a predetermined length, and is formed on at least one support load 28a that protrudes through the sealing member 20 and at least one side surface of the support load 28a. And a locking projection 28c on which the sealing member 20 is locked so that the sealing member 20 cut by the cutter 26 is housed inside the inner lid 14.

  Here, the support load 28a is formed in a bar type extending in the lower direction of the pressing plate 24, and a punched portion 28b having a sharp shape so that the sealing member 20 can be inserted through the end thereof. Is formed.

  The locking projection 28c is formed in an elastically deformable form that can be deflected in the upward direction. When protruding through the sealing member 20, the locking projection 28c is bent in the upward direction while passing through a hole formed by the punch portion 28b. After entering the inside of the sealing member 20 and entering the inside of the sealing member 20, it returns to its original state and is locked to the inner side surface of the sealing member 20.

  Such locking protrusions 28c are formed on both side surfaces of the support load 28a so as to extend in a perpendicular direction by a predetermined length, and are formed on at least one side surface of the support load 28a.

  The connecting portion 30 is formed in a thin dome-shaped film that connects the inner peripheral surface of the inner lid 14 and the outer peripheral surface of the pressing plate 24, and the pressing plate is elastically deformed when the pressing plate 24 is pressed with a predetermined force or more. Guides 24 to move downward.

  Such a connecting portion 30 elastically maintains the current position of the pressing plate 24. That is, when the pressing plate 24 is positioned so as to protrude upward, which is a position where the pressing plate 24 is not pressed, the connecting portion 30 maintains the current position of the pressing plate 24 while maintaining a bulging dome shape. When the pressing plate 24 is pressed with a predetermined force or more, the position where the pressing plate 24 is pressed is maintained while being elastically deformed into a recessed shape.

  On the other hand, the spacer 15 for maintaining the distance between the outer lid 16 and the inner lid 14 is provided so as to be supported on the upper surface of the pressing plate 24 as shown in FIG. Provided on the part 30 side.

  The operation of the sealing member removing unit 22 having the above configuration will be described as follows. Here, since the overall operation of the container lid according to the second embodiment of the present invention is the same as that of the first embodiment except for the sealing member removing unit, the description thereof is omitted.

  In the case of the container lid according to the second embodiment of the present invention, the pressing plate 24 of the sealing member removing unit 22 is covered with the protective plate 13, so that the sealing member 20 is removed after the protective plate 13 is removed. It becomes possible to press.

  Therefore, the user removes the protective plate 13 from the outer lid 16 when the sealing member 20 is to be removed using the sealing member removing unit 22.

  Then, when the user applies a force to the pressing plate 24 and pushes it, the locking portion 28 and the cutter provided on the bottom surface of the pressing plate 24 moved downward by the elastic action of the connecting portion 30 and moved downward. As shown in FIG. 21 or FIG. 23, 26 penetrates the sealing member 20 and enters.

  At this time, the locking member 28c of the locking portion 28 enters the inside of the sealing member 20 through the hole vacated by the punch portion 28b while bending upward while protruding through the sealing member 20, and enters the inside of the sealing member 20 After entering the inside, it is locked to the inner surface of the sealing member 20 while returning to its original state.

  In this state, when the user applies a force downward to the outer lid 16 and rotates it in the opening direction, the first key 40 and the second key 42 are engaged, and the rotational force of the outer lid 16 is transmitted to the inner lid 14. The inner lid 14 is rotated. At this time, the cutter 26 cuts the sealing member 20 in the circumferential direction by the rotation of the inner lid 14.

  When the user rotates the container lid until it is separated from the container 10 and separates it from the container inlet 12, the cut sealing member 20 remains locked to the locking portion 28. Separated from the container inlet 12.

  Meanwhile, the spacer is provided between the outer lid and the inner lid, and moves the outer lid downward with a predetermined force or more to transmit the rotational force in the opening direction of the outer lid to the inner lid. Also, the outer lid is configured to maintain the distance between the outer lid and the inner lid so that the outer lid can only idle in the opening direction with respect to the inner lid, and various configurations are possible.

  Hereinafter, a container lid according to a third embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  24 is a cross-sectional view showing a container lid according to a third embodiment of the present invention, FIG. 25 is a cross-sectional view showing a state where a protective plate is removed from the container lid of FIG. 24, and FIGS. It is the conceptual diagram which showed the operation | movement process of the 1st key and 2nd key of 24 container lids.

  Since the container lid according to the third embodiment of the present invention is the same as the configuration of the second embodiment except for the configuration of the spacer and the reverse rotational force transmission unit, the configuration of the spacer and the reverse rotational force transmission unit is the same. However, the description of other components will be omitted. Of course, the configuration of the third embodiment can be applied to the first embodiment.

  The spacer 250 includes an annular ring portion that protrudes from the upper surface of the inner lid 14 or the bottom surface of the protection plate 13. 24 and 25 show an example in which the ring portion is formed to protrude from the upper surface of the inner lid 14.

  Since the ring portion protrudes from the upper surface of the inner lid 14 or the bottom surface of the protective plate 13, the second key 42 of the outer lid 16 and the first key 40 of the inner lid 14 do not mesh with each other and maintain an interval.

  The height of the ring portion has such a size that the interval between the second key 42 of the outer lid 16 and the first key 40 of the inner lid 14 does not contact each other, or has a size that allows a partial contact. Configured as follows.

  At this time, when the distance between the second key 42 of the outer lid 16 and the first key 40 of the inner lid 14 is set so as not to contact each other, the above-described reverse is performed to facilitate the coupling to the container. It is preferable to additionally provide a rotational force transmission unit.

  On the other hand, when the distance between the second key 42 of the outer lid 16 and the first key 40 of the inner lid 14 is such that the distance between the second key 42 and the first key 40 of the inner lid 14 is in contact with each other, An inclined surface 40b is formed in the opening direction so as to prevent the 2 key 42 from getting over and transmitting the rotational force to the inner lid 14.

  Even if the user applies a force from the outer lid 16 to the inner lid 14 side, the inclined surface 40b rotates when the end of the second key 42 gets over when the outer lid 16 is rotated as shown in FIG. It is formed to an appropriate depth so as to prevent force from being transmitted to the inner lid 14. The depth of the inclined surface 40b is selected to an appropriate value in consideration of the tolerance and deformation of the outer lid 16 and the inner lid 14.

  Accordingly, the spacer 250 keeps the second key 42 of the outer lid 16 and the first key 40 of the inner lid 14 so as not to mesh with each other, so that the inner lid 14 can be maintained even if the user rotates the outer lid 16. If the rotational force is not transmitted to the protective plate 13 and the protective plate 13 is not removed, the opening is impossible.

  On the other hand, when the user tries to open the container lid from the container, the container lid is separated from the container by the following process.

  First, as in the first embodiment or the second embodiment, when the use town removes the protection plate 13, the state shown in FIG. 28 is obtained, and the user can rotate the external lid 16. The rotational force of the outer lid 16 is not transmitted to the inner lid 14 by the inclined surface of the first key 40.

  At this time, when the user applies a force from the outer lid 16 to the inner lid 14 side, the outer lid 16 moves to the inner lid 14 side, so that the first key 40 and the second key 42 as shown in FIG. Are engaged with each other, and the rotational force of the outer lid 16 that causes the user to rotate the outer lid 16 is transmitted to the inner lid 14. Here, the outer lid 16 and the inner lid 14 constituting the container lid are all made of a deformable material such as a plastic material. Therefore, when the user applies a force, the first key 40 and the second lid 14 are deformed by mutual deformation. The key 42 is engaged.

  On the other hand, once the spacer 250 is removed, it cannot be restored to its original state. Therefore, the user can confirm whether or not the container lid can be opened by the presence or absence of the spacer 250.

  The spacer can be variously modified in addition to the annular ring portion.

  Hereinafter, the container lid according to the fourth embodiment of the present invention will be described in detail.

  30 is a cross-sectional view showing a container lid according to a fourth embodiment of the present invention, and FIG. 31 is a cross-sectional view showing a state where the spacer 350 is removed from the container lid of FIG.

  Since the container lid according to the fourth embodiment of the present invention is similar in configuration except for the spacer 350, only the spacer will be described briefly.

  The spacer 350 is separably provided near the lower end of the outer lid 16 or near the lower end of the inner lid 14.

  At this time, the spacer 350 maintains the distance between the second key 42 of the outer lid 16 and the first key 40 of the inner lid 14 in the state as shown in FIGS.

  For example, as shown in FIG. 30, the spacer 350 is connected to the lower end of the outer lid 16 by one or more bridges 351 and supported by the inner lid 14 or the container, and the second key 42 and the inner lid of the outer lid 16. The first key 40 of the lid 14 is configured in a skirt shape that maintains a constant interval.

  At this time, the spacer 350 can be variously modified such as being coupled with the outer lid 16 in a state where a concave groove (cut) separated by incision is formed in addition to the skirt shape.

  On the other hand, as shown in FIG. 31, when the skirt-shaped spacer 350 is removed, as in the third embodiment, when the user applies a force from the outer lid 16 to the inner lid 14 side, 16 can move to the inner lid 14 side, and as shown in FIG. 29, the first key 40 and the second key 42 mesh with each other so that the user can rotate the outer lid 16 to rotate the outer lid 16. Is transmitted to the inner lid 14. Here, since the outer lid 16 and the inner lid 14 constituting the container lid are all made of a deformable material such as a plastic material, when the user applies force, the first key 40 and the second key 42 are mutually deformed. Mesh.

  On the other hand, once the spacer 350 is removed, it is impossible to restore the original shape, so that the user can confirm whether or not the container lid can be opened by the presence or absence of the spacer 350.

  On the other hand, since the container lid according to the present invention is coupled so that the inner lid and the outer lid rotate idly, the coupling force can be transmitted in the closing direction when the outer lid rotates when coupled with the container. It is preferable to provide a reverse rotational force transmission part.

  The reverse rotational force transmission unit can have any configuration as long as the rotational force can be transmitted in the closing direction when the external lid rotates.

  Hereinafter, the container lid according to the fifth embodiment of the present invention will be described in detail.

  32 is a cross-sectional view showing a container lid according to a fifth embodiment of the present invention, and FIGS. 33 and 34 are cross-sectional views showing the IV-IV direction of FIG.

  The container lid according to the fifth embodiment of the present invention has a configuration similar to that of the container lid according to the third embodiment except for the configuration of the reverse rotational force transmission unit. I will explain it. Here, the container lid according to the fifth embodiment will be described by taking, as an example, a container lid that does not include a pressing plate, unlike the third embodiment.

  Here, the spacer 250 is formed so as to protrude from the upper surface of the inner lid 14 or the bottom surface of the protection plate 13 (in this embodiment, the upper surface of the inner lid 14) to form a notch 251 having one or more cuts in the circumferential direction. Having an annular ring portion.

In particular, if the spacer 250 is configured into a plurality of circular plates having respective curvatures, as shown in FIGS. 32 34, configured into a plurality of plate-shaped plate 252 to form a virtual circle C _1.

  As shown in FIGS. 32 to 34, the reverse rotational force transmitting portion is connected to the inner surface of the outer lid 16 so as to be engaged with the notch 251 of the ring portion which is the spacer 250 only in the closing direction of the inner lid 14. One or more reverse rotation protrusions 260 are formed on the outer surface of the inner lid 14. Here, when the spacer 250 is formed on the inner lid 14, the reverse rotation protrusion 260 is formed on the inner surface of the outer lid 16, and when the spacer 250 is formed on the outer lid 16, the reverse rotation protrusion 260. Is formed on the outer surface of the inner lid 14.

  The reverse rotation protrusion 260 is engaged with the notch 251 of the ring portion only in the closing direction of the inner lid 14, and is away from the notch 251 of the ring portion in the opening direction from the engagement surface 261. And an inclined surface 262 formed as described above.

  For example, as shown in FIGS. 32 to 34, the spacer 250 is formed in an annular ring portion so as to support the protective plate 13 on the upper surface of the inner lid 14, and force is applied from the outer peripheral surface or the inner peripheral surface. When added, a plurality of notches 251 are formed with a small thickness so as to bend easily.

At this time, the spacer 250, the side 251a directed in the closing direction in the notch 251 on the basis of the virtual circle C ₁ is outside of the virtual circle C _1, preferably further projects in the reverse rotation protrusion 260 side. And, the spacer 250 is a side 251b oriented in the opening direction in the cutout portion 251 relative to the virtual circle C ₁ is more preferably formed inside the virtual circle C _1.

  One or more reverse rotation protrusions 260 constituting the reverse rotation force transmitting portion are formed on the inner surface of the outer lid 16.

  At this time, the reverse rotation protrusion 260 includes a locking surface 261 formed so as to be locked with the side 251 a facing the closing direction in the notch 251. Here, the reverse rotation protrusion 260 has a cutout portion of the ring portion in the opening direction from the locking surface 261 so that the outer lid 16 is smoothly blocked in the opening direction without being obstructed by the inner lid 14. It is preferable that an inclined surface 262 formed so as to be away from 251 is formed.

  When the outer lid 16 rotates in the closing direction with the above-described configuration, as shown in FIG. 33, the outer lid 16 is latched with the locking surface 261 and the side 251 a facing the closing direction in the notch 251 of the spacer 250. Sixteen rotational forces are transmitted to the inner lid 14.

  However, when the inner lid 16 rotates in the opening direction, as shown in FIG. 34, the locking surface 261 moves the spacer 250 by the inclined surface 262 when moving toward the opening direction 251 b in the notch 251 of the spacer 250. Pushing inward prevents the rotational force of the outer lid 16 from being transmitted to the inner lid 14.

  FIG. 35 is a conceptual diagram showing a case where the outer lid rotates in the closing direction in a modified example of the spacer and the reverse torque transmission unit in the container lid of FIG. 32, and FIG. 36 is a diagram illustrating the case where the outer lid is opened in the container lid of FIG. FIG. 37 is a conceptual diagram showing the time when the outer lid rotates in the closing direction in the container lid of FIG. 35.

  Meanwhile, the spacer 250 and the reverse torque transmission unit can be variously modified. As shown in FIGS. 35 to 37, the spacer 250 is formed as an annular ring, and the reverse torque transmission unit is a spacer. One or more first protrusions 363 formed on the outer peripheral surface of the 250 annular ring portion, and one or more first protrusions formed on the outer lid 16 and locked only in the closing direction with the first protrusion 363. 2 protrusions 364.

  The first protrusion 363 and the second protrusion 364 have protrusions 363a and 364a that are opposed to each other in the closing direction, and inclined surfaces 363b and 364b that are opposite to each other in the opening direction. It is preferable.

  When the outer lid 16 is rotated and the second protrusion 364 is rotated by rotating the outer lid 16 and the outer lid 16 is rotated in the closing direction, the reverse rotational force transmitting unit as described above has the first projection as shown in FIG. The protrusions 363a and 364a of the portion 363 and the second protrusion 364 are interlocked with each other, and the rotational force of the outer lid 16 is transmitted to the inner lid 14 so that the container lid is coupled to the container.

  On the other hand, when the outer lid 16 rotates in the opening direction, as shown in FIG. 36, the first protrusion 363 and the second protrusion 364 are in contact with the inclined surfaces 363b and 364b. The rotational force of the outer lid 16 is prevented from being transmitted to the inner lid 14 over the inclined surface.

  In addition, as shown in FIG. 37, the protective plate 13 has a notch 13a so that the user can observe the second protrusion 364 formed on the external lid 16 side from the outside. .

  38 is a sectional view showing a container lid according to a sixth embodiment of the present invention, FIG. 39 is a sectional view showing an exploded state of FIG. 38, and FIG. 40 is a state where the container lid of FIG. 38 is coupled to the container lid. FIG. 41 is a perspective view showing an inner lid of the container lid of FIG. 38.

  Since the container lid according to the sixth embodiment of the present invention has the same configuration as that of the container lid according to the third embodiment except for the configuration of the reverse rotational force transmitting portion, the reverse rotational force transmitting portion is specifically described for convenience of explanation. I will explain it. Here, unlike the third embodiment, the container lid according to the fifth embodiment will be described as an example having no pressing plate.

  The reverse rotational force transmission unit includes one or more first protrusions 361 formed to be separated or destroyed when a predetermined force or more is applied to the bottom surface of the inner lid 14 (sixth embodiment) or the outer lid 16. When the outer lid 16 rotates in the closing direction, the outer lid 16 is formed on the inner surface of the outer lid 16 or the outer surface of the inner lid 14 so as to contact the first protrusion 361 so as to transmit the rotational force to the inner lid 14. And one or more second protrusions 362.

  The first protrusion 361 and the second protrusion 362 are formed on the inner lid 14 and the outer lid 16, respectively, so that the contents are not sufficiently leaked when the container lid is coupled to the container. In addition, when the outer lid 16 rotates in the closing direction, after the rotational force is transmitted to the inner lid 14, the first protrusion 361 is separated when the inner lid 14 is sufficiently coupled to the container and cannot be rotated any further. Or, by being destroyed, it becomes impossible to transmit a rotational force to the inner lid 14, and the inner lid 14 does not rotate even if the outer lid 16 rotates.

  The first protrusion 361 and the second protrusion 362 are provided so as to be able to transmit a rotational force to each other, and any structure is possible as long as the first protrusion 361 is separated or destroyed. Various configurations such as a configuration inserted into the other are possible.

  For example, the first protrusion 361 is formed to be separably formed on the upper surface of the inner lid 14, and the second protrusion 362 is formed with a concave groove 362 a into which the first protrusion 361 is inserted, and is formed on the bottom surface of the protection plate 362. It is formed. At this time, the first and second protrusions 361 and 362 also serve as spacers, so that no separate spacer is required.

  On the other hand, the first protrusion 361 and the second protrusion 362 can be formed at corresponding positions in the center of the upper surface of the inner lid 14, but the present invention is not limited to this.

  The first protrusion 361 may be formed of one or a plurality of pieces, and the upper edge is preferably formed in a curved surface so that the second protrusion 362 can be easily inserted into the groove 362a. .

  Further, the horizontal cross section of the first protrusion 361 can have various shapes such as a polygon and a star so that the rotational force of the outer lid 16 can be easily transmitted to the inner lid 14.

  The first protrusion 361 performs a predetermined process such as forming a cut or a separation groove when the plastic is injected so that the first protrusion 361 can be easily separated or broken from the inner lid 14.

  Meanwhile, the second protrusion 362 is also formed to be separated or destroyed when a predetermined force or more is applied to the bottom surface of the outer lid 16.

  In the container lid having the above-described configuration, when the outer lid 16 is rotated, the rotational force is transmitted by the mutual coupling of the first protrusion 361 and the second protrusion 362.

  However, when the inner lid 14 is coupled to the container, the inner lid 14 cannot rotate any further, and thus a force that the inner lid 14 resists the rotation of the outer lid 16 is generated. At this time, when the first protrusion 361 exceeds a predetermined force, As shown in FIG. 40, it is separated from the inner lid 14.

  On the other hand, after the first projecting portion 361 is separated, even if the outer lid 16 is rotated, the rotational force cannot be transmitted to the inner lid 14, so that the inner lid 14 can be rotated in any direction. Without rotation, the user cannot separate the container lid from the container without removing the protective plate 13.

  The above is only a description of some of the preferred embodiments that can be implemented by the present invention, and as is well known, the scope of the present invention should not be limited to the above embodiments and should not be analyzed. All the technical ideas of the present invention and the technical ideas based on the technical ideas should be included in the scope of the present invention.
