Abstract

A child-resistant cap comprises: an inner cap mounted at a vessel inlet of a vessel; an outer cap disposed at an outer circumferential surface of the inner cap so as to perform an idling with the inner cap; a rotation force transmitting portion disposed between the inner cap and the outer cap for transmitting a rotation force of the outer cap to the inner cap only when the outer cap is downwardly moved with a force more than a certain degree; and a sealing member removing unit formed at the inner cap for removing a sealing member sealed at the vessel inlet when the inner cap is detached from the vessel inlet, and storing the removed sealing member in the inner cap. Since the sealing member removing unit is integrally formed at the cap, the scaling member is automatically removed at the time of opening the cap. Accordingly, the sealing member needs not to be additionally removed, and thus a usage convenience is enhanced. Furthermore, under a construction that the outer cap maintains an upwardly moved position from the inner cap by an elastic force, the cap can be opened only by downwardly moving the outer cap with a force more than a certain degree. Accordingly, a child can be more effectively protected.

Description

Another object of the present invention is to provide a child-proof cap capable of preventing external force from pressing on the clogging element removal assembly by protecting the clogging element removal assembly mounted on the inner cap with a protective plate to protect the clogging element removal assembly on the outer surface of the outer cap

Another object of the present invention is to provide a child-resistant lid capable of increasing safety by enabling a child to drink the contents of the container in small portions when the lid is opened by mistake, by releasing the contents in small portions through a small hole formed in the inlet opening of the container by forming a hole in the blocking element due to the partial removal of the blocking element.

Technical solution

To achieve these and other advantages corresponding to the purposes of this invention, carried out and described here in general terms, a lid is obtained that is not accessible for opening by children, which contains: an internal cap installed on the inlet of the vessel; an outer cap located on the outer peripheral surface of the inner cap in such a way that it can perform idle rotation relative to the inner cap; a part for transmitting rotational force, located between the inner cap and the outer cap, for transmitting rotational force from the outer cap to the inner cap only when the outer cap moves downward under the action of a force that exceeds a specified value; and a plugging element removal assembly formed on the inner cap for removing the plugging element sealed to the vessel inlet when the inner cap is separated from the vessel inlet and retaining the removed plugging element in the inner cap.

At the upper end of the outer cap, an elastic element is formed, which is supported by the upper surface of the inner cap and creates an elastic force that ensures that the outer cap maintains the state of movement upward from the inner cap.

The part for transmitting the rotational force includes a first engaging protrusion, receding from the lower outer circumferential surface of the inner cap in the circumferential direction with the same gap with a specified width; and a second engaging protrusion that extends from the inner circumferential surface of the outer cap in the circumferential direction with an equal gap of a predetermined width and engages with the first engaging protrusions when the outer cap is pushed down.

The unit for removing the blocking element includes a pressure plate located in the inner cap in such a way that it can move up and down; a cutter formed on the edge of the lower surface of the pressure plate in the circumferential direction for piercing the sealing member when the pressure plate is pressed and cutting the sealing member when the inner cap rotates; an engaging part, receding downwardly on the lower surface of the pressure plate, for holding the sealing element, cut off by the cutter, in the inner cap; and a connecting part which is formed between the outer ring surface of the pressure plate and the inner ring surface of the inner cap and is elastically transformed so that the pressure plate can move up and down.

According to another variant of the implementation of this invention, the lid, inaccessible for opening by children, contains: an internal cap installed on the inlet opening of the vessel, through which the contents of the vessel are released to the outside; an outer cap located on the outer annular surface of the inner cap so that it can move up and down; a slotted part formed between the outer annular surface of the inner cap and the inner annular surface of the outer cap for transmitting the rotational force of the outer cap to the inner cap; and a locking assembly formed between the outer cap and the vessel inlet for locking the outer cap when the inner cap is mounted on the vessel inlet.

Beneficial effects

The child-resistant cap of the present invention, having the above construction and function, has the advantage that, since the inner cap is equipped with an unclogging assembly, if the pressure plate of the unclogging assembly is first pressed and then the lid is opened, the sealing element is automatically removed from the inlet of the vessel. Accordingly, the usability increases.

In addition, the child-resistant cap of the present invention has the advantage that since the closure member is automatically removed by the closure removal assembly, the sanitary problem arising when the user's hand comes into contact with the inlet can be solved. through the opening of the vessel to remove the blocking element.

In addition, the child-resistant cap of the present invention has the advantage that since the outer cap can maintain a position moved upwardly from the inner cap due to the elastic member formed on the outer cap, the first engaging protrusion of the inner the cap can be separated from the second engaging projection of the outer cap. Accordingly, even if the child rotates the outer cap, the rotational force from the outer cap is not transmitted to the inner cap, and thus the child can be more effectively protected.

In addition, the child-resistant cap of the present invention has the advantage that, since an inclined surface is formed between the first engaging protrusion and the second engaging protrusion, even if the child rotates the outer cap, the second engaging protrusion slides along the inclined surface of the first engaging projection. Accordingly, the rotational force from the outer cap is not transmitted to the inner cap and thus the child can be more effectively protected.

In addition, the child-resistant cap of the present invention has the advantage that since the closure element removal assembly formed on the inner cap is protected by a protective plate formed on the outer surface of the outer cap, external force is prevented on the block removal assembly when it is open to the outside.

In addition, the child-resistant cap of the present invention has the advantage that, since an opening of a predetermined size is formed in the closure member, by partial removal of the closure member by the closure removal assembly, the contents of the container are released out through the opening a little at a time. Accordingly, even if the child drinks the contents of the container, a small amount of the contents is available to the child and thus the child can be protected from the contents.

In addition, the childproof cap according to the present invention has the advantage that a hole of a predetermined shape is formed in the closure member by the closure member removal assembly formed on the inner cap, and the opening can be formed differently according to the type the contents of the vessel. Accordingly, the child can be more reliably protected.

Next, the child-proof lid according to the invention will be described in more detail with reference to the attached drawings.

Fig. 3 shows a view of the child-proof lid according to the first embodiment of the present invention, Fig. 4 shows a perspective view of the inner cap of the child-proof lid according to the first embodiment of the present invention, and Fig. 5 shows a view in perspective with a section of the outer cap of the lid, inaccessible for opening by children, corresponding to the first variant of the implementation of this invention.

The lid, inaccessible for opening by children, corresponding to the first variant of the implementation of this invention, contains an internal cap 14, installed on the inlet 12, through which the contents of the vessel 10 are released to the outside; an outer cap 16 located on the outer annular surface of the inner cap 14 so that it can perform idle rotation relative to the inner cap 14, a part 18 for transmitting rotational force located between the inner cap 14 and the outer cap 16 for transmitting rotational force from the outer cap 16 to the inner cap 14 only when the outer cap 16 is moved down with a force that exceeds the specified value; and a plug removal assembly 22 formed on the inner cap 14 for removing the plug 20 sealed to the vessel inlet 12 when the inner cap 14 is separated from the vessel inlet 12 and retaining the removed plug 20 in the inner cap 14.

The container 10 contains substances harmful to the child, such as poisonous drugs, detergents, home remedies, etc. A plugging element 20 for protecting the contents of the vessel 10 by plugging the inlet opening 12 of the vessel is attached to the inlet opening 12 of the vessel, through which the contents of the vessel 10 are released to the outside. The plugging element 20 is formed of paper or a thin aluminum plate, which can be easily removed with a knife, etc.

The inner cap 14 has a cylindrical shape with open upper and lower ends and is equipped with a node 22 for removing the blocking element. On the lower inner annular surface, an enclosing threaded part 26 is formed, which is connected by a groove with an enclosing threaded part 24, formed on the outer annular surface of the inlet opening 12 of the vessel. In addition, from the upper inner annular surface of the encompassing threaded part 26, a part 28 that is glued, for gluing to the upper end of the inlet opening 12 of the vessel, recedes in the circumferential direction. An anti-separation sponge 30 extends from the lower outer annular surface of the inner cap 14 to prevent separation of the inner cap 14 from the outer cap 16.

The outer cap 16 is mounted on the inner cap 14 so that it can move up and down, and it has a cylindrical shape with open upper and lower ends. A plurality of convex-concave protrusions 32 are formed on the outer annular surface of the outer cap 16 to facilitate the rotation of the outer cap 16 by the user's hand, and from the lower inner annular surface of the outer cap 16, an anti-separation projection 34, blocked by an anti-separation sponge 30 of the inner cap 14, recedes.

On the upper end of the outer cap 16, an anti-detachment projection 36 is formed to prevent the inner cap 14 from being separated in the direction of the upper side of the outer cap 16. In addition, an elastic member 38 is formed on the anti-separation projection 36, which is held on the upper surface of the inner cap 14 and maintains a movable state of the outer cap 16 in the direction of the upper side of the inner cap 14

The elastic member 38 is formed of a thin film that is arbitrarily bent and creates a predetermined elastic force, and its end is held by the upper surface of the inner cap 14. The elastic member 38 exerts an elastic force on the outer cap 16 so that the outer cap 16 can maintain the upwardly moved state.

When the outer cap 16 is pushed down, the elastic element 38 is elastically transformed, and the outer cap 16 moves down. When the force applied to the outer cap 16 is removed, the outer cap 16 is moved upward by the spring force of the spring element 38, thus restoring the original position.

As shown in Fig.4 and 5, the part 18 for transmitting the rotational force contains the first engaging projection 40, protruding on the lower annular surface of the inner cap 14 in the circumferential direction with the same gap and with a certain width; and a second engaging projection 42, which is recessed on the inner annular surface of the outer cap 16 in the circumferential direction with the same gap and with a defined width and is inserted between: the first engaging projections 40 when the outer cap 16 is pressed down so that it is blocked by the first engaging projection 40.

The first engaging protrusion 40 is formed on the outer annular surface of the inner cap 14 with the same gap, while at the upper end of the first engaging protrusion 40, an inclined surface 46 having a certain angle of inclination is formed. When the second engaging protrusion 42 engages with the first engaging protrusion 40 to a certain extent, the second engaging protrusion 42 can slide on the inclined surface 46 .

A second engaging protrusion 42 is formed on the inner annular surface of the outer cap 16 with the same gap and with the same inclined surface 48 corresponding to the surface of the first engaging protrusion 40 at the lower end of the second engaging protrusion 42. When the inclined surface 48 comes into contact with the inclined surface of the first engaging protrusion 40, the second engaging protrusion 42 slides along the inclined surface 46.

As shown in Fig.b, when the outer cap 16 is pressed by the child, the elastic force generated by the elastic member 38 acts on the outer cap 16 and, thus, the outer cap 16 is not fully pressed. Thus, the second engaging protrusion 42 of the outer cap 16 is not fully inserted into the first engaging protrusion 40 of the inner cap 14 and, thus, the inclined surface 48 of the second engaging protrusion 42 slides on the inclined surface 46 of the first engaging protrusion, even if the outer cap 16 is rotated. As a result, the rotational force of the outer cap 16 is not transmitted to the inner cap 14, thus preventing the cap from opening.

The plug removal assembly 22 includes a pressure plate 50 located in the inner cap 14 so that it can move up and down and be pressed by the user, a cutter 52 formed on the edge of the lower surface of the pressure plate 50 in a circumferential direction for piercing the plug 20, when the cap rotates, the engaging portion 54 projecting downwardly on the lower surface of the pressure plate 50 to lock the sealing member 20 so that the sealing member 20 cut by the cutter 52 can be held in the inner cap 14, and the connecting portion 56 formed between the outer annular surface of the pressure plate and the inner annular surface of the inner cap 14, to guide the pressure plate 50 to move up and down and maintain the displaced position of the pressure plate 50 by its elastic force.

The pressure plate 50 is formed in a disk configuration having a diameter smaller than the inner diameter of the inner cap 14 and is preferably located below the upper surface of the inner cap 14.

As shown in Fig.7, the cutter 52 includes a plurality of support parts 60 formed on the edge of the lower surface of the pressure plate 50 with the same gap, the first pointed cutting part 62 formed on the lower end of the holding part 60 and moved downward when the pressure plate 50 is pressed to piercing the closure element 20, and a second cutting part 64 formed on at least one side surface of both side surfaces of the holding part 60 for cutting the closure element 20 of a circular configuration when rotating in a state of contact with the inner annular surface of the inlet opening 12 of the vessel when the inner cap 14 rotates .

As shown in Fig. 8, the engaging part 54 includes a support rod 66, receding from the lower surface of the pressure plate 50 with a certain length, for piercing the blocking element 20, and at least one engaging protrusion 68 formed on the side surface of the support rod 66, for engaging the blocking element element 20 so that the closure element 20 cut by the cutter 52 can be retained in the inner cap 14.

The support rod 66 is formed in the form of a rod extending downward from the pressure plate 50, and a pointed piercing part 70 is formed at the end of the support rod 6b for piercing the blocking element 20.

The engaging protrusion 68 is formed with the possibility of elastic transformation and bends upward at the moment of piercing the plugging member 20, thus passing through the opening formed by the piercing part 70 and entering the plugging member 20. Then, the engaging protrusion 68 is straightened to its original state after being located on the inner side of the plugging of the element 20, thus engaging the inner surface of the blocking element 20.

At least one engaging projection 68 perpendicularly recedes from both side surfaces of the support rod 6b for some distance. Between the outer annular surface of the pressure plate 50 and the inner annular surface of the inner cap 14, a connecting part 56 is formed in the form of a thin film, which has a dome-shaped shape.

The connecting part 56 is elastically transformed when the pressure plate 50 is pressed with a force that exceeds a predetermined amount, thus guiding the pressure plate 50 to move downward.

The connection part 56 elastically supports the current position of the pressure plate 50. That is, when the pressure plate protrudes upward, the connection part 56 has a convex dome shape and supports the current state of the pressure plate 50. However, when the pressure plate 50 is pressed with a force exceeding the determined value, the connecting part 56 elastically transforms into a concave shape and maintains the pressed state of the pressure plate 50.

Now the operation of the childproof cover will be described.

Figures 9 and 10 show the operation of a childproof cover according to the present invention.

When the pressure plate 50 formed on the inner cap 14 is pushed down to release the contents of the container 10 to the outside, the connecting part 56 is elastically transformed, and the pressure plate 50 moves down. In this case, the first cutting part 62 of the cutters 52 formed on the lower surface of the pressure plate pierces the edge of the blocking member 20, and the support rod 66 of the engaging part 54 pierces the center of the blocking member 20.

At the moment of piercing the plugging element 20, the engaging protrusion 68 of the engaging part 54 is bent upward so that it passes through the hole pierced by the piercing part 70 of the support rod 66. When the engaging protrusion 68 is located on the inner surface of the plugging element 20, it is elastically transformed into the original state , i.e. the protruding state.

Then, when the outer cap 16 is moved down by the user's hand with a force that exceeds the determined value, the elastic element 38 is elastically transformed. As a result, the second engaging protrusion 42 formed on the outer cap 16 is inserted between the first engaging protrusions 40 formed on the inner cap 14, causing them to engage with each other. In addition, when the outer cap 16 is rotated, the rotational force from the outer cap 16 is transmitted to the inner cap 14, as a result of which the inner cap 14 is separated from the inlet opening 12 of the vessel due to rotation.

At the same time, the cutter 52 rotates in a state of contact with the inner annular surface of the inlet opening 12 of the vessel, and the second cutting part 64, formed on both side surfaces of the support part 60, cuts the plugging element 20 of a circular shape. As the closure element 20, which is removed from the inlet opening 12 of the vessel, is captured by the engaging protrusion 68 of the engaging part 54, it is separated from the inlet opening 12 of the vessel together with the inner cap 14, thus remaining in the inner cap 14.

If the contents of the vessel 10, from which the closure element 20 has been removed, are released through the vessel inlet 12 and then the cap is re-installed on the vessel inlet 12, the outer cap 16 moves to the upper side of the inner cap 14, and the first engaging projection 40 moves away from the second engaging protrusion 42. Accordingly, even if the child rotates the outer cap 16, the rotational force from the outer cap 16 is not transmitted to the inner cap 14.

In addition, even if the child moves the outer cap 16 down, due to a weak force, the outer cap 16 does not completely move down due to the elastic force of the elastic member 38. In this state, even if the outer cap 16 is rotated, the inclined surface 48 of the second engaging projection 42 slides along the inclined surface 46 of the first locking protrusion 40, and thus the inner cap 14 does not open.

Fig. 11 shows a cross-sectional view of the lid, which is inaccessible for opening by children, according to the second variant of the implementation of this invention, Fig. 12 shows a cross-sectional view made along the line B-B in Fig. 11, and Fig. 13 shows a cross-sectional view, executed along the C-C line in Fig. 11.

The lid, inaccessible for opening by children, according to this invention, contains: an internal cap 80, installed on the inlet 12 of the vessel 10, through which the contents of the vessel 10 are released to the outside; an outer cap 82 located on the outer annular surface of the inner cap 80 so that it can move up and down; a slotted part 85 formed between the outer annular surface of the inner cap 80 and the inner annular surface of the outer cap 82, for transmitting the rotational force from the outer cap 82 to the inner cap 80; a locking assembly 84 formed between the outer cap 82 and the vessel inlet 12 for locking the outer cap 82 when the inner cap 80 is installed on the vessel inlet 12; and a plug removal assembly 22 formed on the inner cap 80 for removing the plug 20 sealed to the vessel inlet 12 when the inner cap 80 is separated from the vessel inlet 12 and retaining the removed plug 20 in the inner cap 80.

The inner cap 80 has a cylindrical shape with open upper and lower ends and has a node 22 for removing the blocking element. On the lower inner annular surface of the inner cap 80, an enclosing threaded part 88 is formed, which is connected along the cut with the connecting threaded part 86, formed on the outer annular surface of the inlet opening 12 of the vessel.

The outer cap 16 has a cylindrical shape with open upper and lower ends, and stoppers 90 and 92 are formed at the upper and lower ends, respectively, to prevent the inner cap 80 from separating. A plurality of convex-concave protrusions 94 are formed on the outer annular surface of the outer cap 16 to facilitate rotation of the outer cap 16 by the user's hand.

The slotted part 85 includes a first engagement protrusion 81 formed on the outer annular surface of the inner cap 80 in the circumferential direction with the same gap, and a second engagement protrusion 83 formed on the inner annular surface of the outer cap 82 in the circumferential direction with the same gap and engaged with the first engagement speech 81.

As shown in Fig.13, the locking assembly 84 includes a first locking protrusion 98 formed on the edge of the flange part 96 in the circumferential direction with the same gap, and the flange part 96 recedes from the outer annular surface of the lower surface of the inlet opening 12 of the disc-shaped vessel; and a second locking protrusion 100 that is formed on the inner annular surface of the lower end of the outer cap 82 with the same gap and engages with the first locking protrusion 98, thus providing locking.

The first locking protrusion 98 is formed so that it has a toothed configuration and is provided with an inclined surface 102 having a defined angle of inclination on one side thereof. The second locking protrusion 100 has the same inclined surface 104 as the inclined surface 102 of the first locking protrusion 98 , on a surface facing the inclined surface 102 of the first locking protrusion 98 .

When the outer cap 82 is rotated to move down, the second locking protrusion 100 formed on the outer cap engages with the first locking protrusion 98 formed on the inlet opening 12 of the vessel. At this point, if the inner cap 80 does not completely cover the inlet opening 12 of the vessel, the inclined surface 104 of the second locking protrusion 100 slides over the inclined surface 102 of the first locking protrusion 98 and thus rotates. In contrast, if the inner cap 80 completely covers the inlet opening 12 of the vessel, the second locking protrusion 100 is inserted between the first locking protrusions 98 and, thus, rotation of the outer cap 82 is prevented.

The unit 22 for removing the blocking element has the same construction and principle of operation as those indicated above in relation to the first embodiment of the invention, and thus its detailed description will be omitted.

Next, the operation of the child-resistant lid according to the second embodiment of the present invention will be described.

Fig. 14 shows a view showing the working state of the child-resistant lid according to the second embodiment of the present invention.

When the outer cap 82 is pulled up, the outer cap 82 slides on the outer annular surface of the inner cap 80 and moves up. At the same time, the second locking protrusion 100 formed on the outer cap 82 will separate from the first locking protrusion 98 formed on the inlet 12 of the vessel, and thus the locked state of the outer cap 82 is unlocked.

In this state, if the outer cap 82 is rotated, the inner cap 80, which is splined to the outer cap 82, rotates with it and is separated from the inlet 12 of the vessel.

At this point, the plugging element 20, hermetically attached to the inlet opening 12 of the vessel, is removed by the plugging element removal assembly 22 and retained in the inner cap 80.

Then, if the inner cap 80 is re-installed on the vessel inlet 12, the second locking protrusions 100 formed on the inner annular surface of the outer cap 82 are engaged with the first locking protrusions 98 formed on the vessel inlet 12. Accordingly, the outer cap 82 is locked and thus cannot be opened by a child.

Fig. 15 shows a perspective view of the lid, which is not accessible for opening by children, corresponding to the third variant of the implementation of this invention, Fig. 1b6 shows a cross-sectional view of the lid, which is not accessible for opening by children, corresponding to the third variant of implementation of this invention, and Fig. 17 shows the view in the perspective of the inner cap of the child-proof lid according to the third embodiment of the present invention.

The child-resistant cover according to the third embodiment of the present invention includes: an inner cap 14 installed on the inlet 12 of the vessel 10, through which the contents of the vessel are discharged to the outside; the outer cap 16 is located on the outer annular surface of the inner cap 14 in such a way that it performs idle rotation relative to the inner cap 14; part 18 for transmitting the rotational force, formed between the inner cap 14 and the outer cap 16, for transmitting the rotational force from the outer cap 16 to the inner cap 14 only when the outer cap 16 is moved down by a force that exceeds the specified value; a plug removal assembly 22 formed on the inner cap 14 for removing the plug 20 sealed to the vessel inlet 12 when the inner cap 14 is separated from the vessel inlet 12 and retaining the removed plug 20 in the inner cap; and a protective plate 13, movably mounted on the upper surface of the outer cap 16, to protect the assembly 22 of removing the blocking element mounted on the inner cap.

The inner cap 14 and the outer cap 16 have a structure and functions similar to those in the first embodiment of the present invention, and thus their detailed description will be omitted.

The protective plate 13 is formed on the upper annular surface of the outer cap 16 with a gap and in the shape of a disk. In addition, between the outer annular surface of the protective plate 13 and the upper inner annular surface of the outer cap 16, a plurality of connecting ribs 17 are formed, which intersect when the protective plate 13 moves downward, and which maintain the fixed state of the protective plate 13 relative to the outer cap 16.

The connecting ribs 17 are formed so that they are cut when a predetermined force is applied to them, and guide the protective plate 13 to move downward when the protective plate 13 is pressed and cut.

Between the outer annular surface of the protective plate 13 and the upper inner annular surface of the outer cap 16 with a defined gap, a plurality of guide ribs 15 are placed, which thus guide the protective plate 13 to move downward in the state of connection with the outer cap 16.

The guide rib 15 is formed in a 5-shaped configuration and has one end mated to the inner annular surface of the outer cap 16 and the other end mated to the outer annular surface of the shield plate 13. As the shield plate 13 moves downward, the guide rib 15 is extended, thus , guiding the protective plate 13 to move down and maintaining the mating state of the protective plate 13 with the outer cap 16. The guide rib 15 is inserted into the groove 21 formed in the outer annular surface of the protective plate 13.

In the 5-shaped bent part of the guide rib 15, a connecting tape 19 is formed, which has a small thickness, so that the guide rib 15 supports the 5-shaped shape. The connecting tape 19 is cut when the protective plate 13 moves down.

The protective plate 13 protects the node 22 of removing the blocking element from external force by preventing the opening of the node 22 of removing the blocking element to the outside. When the protective plate 13 is pressed down by the user to manipulate the assembly 22 of removing the clogging element, the connecting rib 17 placed between the protective plate 13 and the outer cap 16 is cut, the protective plate 13 moves down, and the pressure plate 50 of the assembly 22 of removing the clogging element is pressed. At this moment, the guide rib 15, which has a 5-shaped shape and is placed between the protective plate 13 and the outer cap 16, is extended, thus guiding the protective plate 13 to move downward and maintaining the mated state of the protective plate 13 with the outer cap 16.

Part 18 for transmitting the rotational force contains the first engaging projection 40, receding from the lower outer annular surface of the inner cap 14 in the circumferential direction with the same gap and with a certain width; and a second engaging protrusion 42 that recedes from the inner annular surface of the outer cap 16 in the circumferential direction with the same gap and with a defined width and engages with the first engaging protrusions 40 when the outer cap 16 is pressed down.

The first engaging protrusion 40 and the second engaging protrusion 42 have a structure similar to that described above with respect to the first embodiment of the invention, and thus their detailed description will be omitted

The node 22 of removing the blocking element includes a pressure plate 50 located in the inner cap 14 so that it can move up and down; a cutter 52 formed on the outer edge of the lower surface of the pressure plate 50 for penetrating the closure member 20 when the pressure plate 50 is pressed and cutting the closure member 20 when the cap rotates; an engaging portion 54 projecting downwardly on the lower surface of the pressure plate 50 to engage the plugging member 20 so that the plugging member 20 cut by the cutter 52 can be held in the inner cap 14, and a connecting portion 56 formed between the outer annular surface of the pressing plate 50 and the inner ring surface of the inner cap 14, to guide the pressure plate 50 to move up and down and maintain the displaced position of the pressure plate 50 by its elastic force.

The node 22 of removing the blocking element has a design and principle of operation similar to those indicated above in the first embodiment of the invention, and thus, its detailed description will be omitted.

Next, the operation of the child-resistant lid according to the third embodiment of the present invention will be described.

Figures 18 and 19 are views showing the working state of a child-proof lid according to a third embodiment of the present invention.

When the protective plate 13 mated with the outer cap 16 is pressed by the user to release the contents of the container 10 to the outside, the connecting rib 17 placed between the protective plate 13 and the outer cap 16 is cut and the protective plate 13 moves downward, thus pressing on the pressure plate 50 of the node 22 of the removal of the blocking element. At this moment, the guide rib 15, which has

C-shaped and placed between the protective plate 13 and the outer cap 16, is extended, thus to guide the protective plate 13 to move downward and maintain the mating state of the protective plate 13 with the outer cap 16.

In this case, when the pressure plate 50 is moved down by the protective plate 13, the connecting part 56 is elastically transformed. In this case, the first cutting part 62 of the cutters 52 formed on the lower surface of the pressure plate 50 penetrates through the edge of the blocking member 20, and the support rod 66 of the engaging part 54 pierces the center of the blocking member 20.

At the moment of piercing the plugging element 20, the engaging protrusion 68 of the engaging part 54 is bent upward, thus passing through the hole pierced by the piercing part 70 of the support rod 66. When the engaging protrusion 68 is located on the inner surface of the plugging element 20, it is elastically transformed into the original state, that is, in an extended state.

Then, when the outer cap 16 is moved down by the user's hand with a force that exceeds the determined value, the elastic element 38 is elastically transformed. As a result, the second engaging protrusion 42 formed on the outer cap 16 is inserted between the first engaging protrusions 40 formed on the inner cap 14, and thus they are engaged with each other.

In addition, when the outer cap 16 is rotated, the rotational force from the outer cap 16 is transmitted to the inner cap 14, and thus the inner cap 14 is separated from the inlet opening 12 of the vessel when it is rotated.

At this moment, the cutter 52 rotates in a state of contact with the inner annular surface of the inlet opening 12 of the vessel, and the second cutting part 64 formed on both side surfaces of the support part 60 cuts out the plugging element 20 in a circular shape. As the closure member 20, which has been removed from the vessel inlet 12, is held by the engaging projection 68 of the engaging portion 54, it is separated from the vessel inlet 12 together with the inner cap 14, thus remaining in the inner cap 14.

If the contents of the vessel 10, from which the sealing element 20 has been removed, are discharged to the outside through the inlet opening 12 of the vessel and then the cap is again installed on the inlet opening 12 of the vessel, the outer cap 16 is moved to the upper side of the inner cap 14 by the elastic force of the elastic element 38, and the first engaging projection 40 away from the second engaging projection 42. Accordingly, even if the child rotates the outer cap 16, the rotational force from the outer cap 16 is not transmitted to the inner cap 14.

In addition, even if the child moves down the outer cap 16, due to a weak force, the outer cap 16 does not move down completely due to the elastic force of the elastic member 38. In this state, even if the outer cap 16 rotates, the inclined surface 48 of the second engaging protrusion 42 slides along inclined surface 46 of the first locking protrusion 40, and thus the inner cap 14 does not open.

Figure 20 shows a cross-sectional view of a child-proof lid according to the fourth embodiment of the present invention.

The child-resistant cover according to the fourth embodiment of the present invention includes: an inner cap 80 installed on the inlet 12 of the vessel 10, through which the contents of the vessel are discharged to the outside; an outer cap 82 located on the outer annular surface of the inner cap 80 so that it can move up and down, a splined portion 85 formed between the outer annular surface of the inner cap 80 and the inner annular surface of the outer cap 82 to transmit the rotational force from the outer cap 82 to the inner cap 80; a locking assembly 84 formed between the outer cap 82 and the vessel inlet 12 to lock the outer cap 82; a plug removal assembly 22 formed on the inner cap 80 for removing the plug 20 sealed to the vessel inlet 12 when the inner cap 80 is separated from the vessel inlet 12 and retaining the removed plug 20 in the inner cap 80; and a protective plate 13 mounted on the upper surface of the outer cap 82 in such a way that it can move downward to protect the assembly 22 of removing the blocking element mounted on the inner cap 80.

The inner cap 80 has a cylindrical shape with open upper and lower ends and is equipped with a node 22 for removing the blocking element located in it. On the lower inner annular surface of the inner cap 80, an enclosing threaded part 88 is formed, connected along the cut with an enclosing threaded part 86, formed on the outer annular surface of the inlet opening 12 of the vessel.

The outer cap 82 has a cylindrical shape with open upper and lower ends, and stoppers 90 and 92 are formed at the upper and lower ends, respectively, to prevent the inner cap 80 from separating. A plurality of convex-concave projections 94 are formed on the outer ring surface of the outer cap 82 to facilitate rotation of the outer cap 82 by the user's hand.

The protective plate 13 is formed on the upper inner annular surface of the outer cap 82 with a defined gap and in the shape of a disk. Since the protective plate 13 has a structure similar to that described above for the third embodiment of the invention, its detailed description will be omitted.

The slotted part 85 includes a first engagement protrusion 81 formed on the outer annular surface of the outer cap 80 in the circumferential direction with the same gap, and a second engagement protrusion 83 formed on the inner annular surface of the outer cap 82 in the circumferential direction with the same gap and engaged with the first engagement speech 81.

The locking assembly 84 includes a first locking protrusion 98 formed on the edge of the flange part 96 in the circumferential direction with the same gap, and the flange part 96 recedes from the outer annular surface of the lower surface of the inlet opening 12 of the disc-shaped vessel; and a second locking protrusion 100 that is formed on the inner annular surface of the lower end of the outer cap 82 with the same gap and engages with the first locking protrusion 98, thus locking.

The first locking protrusion 98 and the second locking protrusion 100 of the locking assembly 84 have a structure and functions similar to those indicated above with respect to the second embodiment of the invention and, thus, their detailed description will be omitted.

The unit 22 for removing the blocking element has the construction and functions described in relation to the first embodiment of the invention, and thus their detailed description will be omitted.

Next, the operation of the childproof cover according to the fourth embodiment of the present invention will be described.

Figures 21 and 22 are views showing the operation of the childproof cover according to the fourth embodiment of the present invention.

When the protective plate 13 is pressed down, the plug removal assembly 22 pierces the plug 20 sealed to the inlet 12 of the vessel as described above with respect to the first embodiment of the invention.

Then, when the outer cap 82 is pulled up, the outer cap 82 slides on the outer annular surface of the inner cap 80 and moves up. At this moment, the second locking protrusion 100 formed on the outer cap 82 is separated from the first locking protrusion 98 formed on the inlet opening 12 of the vessel, and thus the locked state of the outer cap 82 is unlocked.

In this state, if the outer cap 82 is rotated, the inner cap 80, which is splined to the outer cap 82, rotates with it and is separated from the inlet 12 of the vessel.

At this point, the plugging element 20, hermetically attached to the inlet opening 12 of the vessel, is removed by the plugging element removal assembly 22 and retained in the inner cap 80.

Then, if the inner cap 80 is installed on the vessel inlet 12 again, the second locking protrusions 100 formed on the inner annular surface of the outer cap 82 are engaged with the first locking protrusions 98 formed on the vessel inlet 12. Accordingly, the outer cap 82 is locked and thus cannot be opened by a child.

Figure 23 shows a perspective view of a child-resistant lid according to a fifth embodiment of the present invention, and Figure 24 shows a cross-sectional view of a child-resistant lid according to a fifth embodiment of the present invention.

The lid, inaccessible for opening by children, corresponding to the fifth variant of the implementation of this invention, contains an internal cap 14, installed on the inlet opening 12 of the vessel, through which the contents of the vessel 10 are released to the outside; the outer cap 16 is located on the outer annular surface of the inner cap 14 in such a way that it performs idle rotation relative to the inner cap 14; part 18 for transmitting the rotational force, located between the inner cap 14 and the outer cap 16, for transmitting the rotational force from the outer cap 16 to the inner cap 14 only when the outer cap 16 is moved down by a force that exceeds the specified value; and a plug removal assembly 22 formed on the outer cap 16 for removing the plug 20 sealed to the vessel inlet 12 and retaining the removed plug 20 in the inner cap 14.

The inner cap 14 has a cylindrical shape with open upper and lower ends. On the lower inner annular surface of the inner cap 14, an enclosing threaded part 26 is formed, connected along the cut with an enclosing threaded part 24, formed on the outer annular surface of the inlet opening 12 of the vessel. In addition, from the upper inner annular surface of the encompassing threaded part 26 in the circumferential direction, the glued part 28 recedes for gluing to the upper end of the inlet opening 12 of the vessel. An anti-separation sponge 30 extends from the lower outer annular surface of the inner cap 14 and is designed to prevent the inner cap 14 from separating from the outer cap 16.

The outer cap 16 is mounted on the inner cap 14 so that it can move up and down, and has a cylindrical shape with open upper and lower ends. A plurality of convex-concave protrusions 32 are formed on the outer annular surface of the outer cap 16 to facilitate the rotation of the outer cap 16 by the user's hand, and from the lower inner annular surface of the outer cap 16, a protrusion 34 to prevent separation, blocked by a sponge 30 to prevent separation of the inner cap 14, protrudes.

On the upper inner annular surface of the outer cap 16, a protrusion 36 to prevent separation recedes in an annular shape to prevent separation of the inner cap 14 in the direction of the upper side of the outer cap 16. In addition, on the lower surface of the protrusion 36 to prevent separation, an elastic member 38 is formed, which is supported by the upper surface of the inner cap 14 and supports the moved state of the outer cap 16 to the upper side of the inner cap 14. On the inner annular surface of the protrusion 36 to prevent separation, a knot 22 is formed for removing the blocking element.

The elastic member 38 is formed in the form of a thin film that is arbitrarily bent and generates a predetermined elastic force, and its end is supported by the upper surface of the inner cap 14. The elastic member 38 creates an elastic force that affects the outer cap 16 in such a way that the outer cap 16 can keep moved up state.

When the outer cap 16 is pushed down, the elastic member elastically transforms and the outer cap 16 moves down. When the action of the force applied to the outer cap 16 is stopped, the outer cap 16 is moved up by the elastic force of the elastic member 38, thus restoring the original position.

The rotational force transmission part 18 has a structure and functions similar to those indicated above in relation to the first embodiment of the invention, and thus its detailed description will be omitted.

The node 22 of removing the blocking element contains a pressure plate 50, fixed on the upper inner annular surface of the outer cap 16 and moved down to unlock the blocked state when pressed with a certain force; a plurality of cutters 52 formed on the outer edge of the lower surface of the pressure plate 50 in the circumferential direction for piercing the sealing member 20 when the pressure plate 50 is pressed and cutting the sealing member 20 when the cap rotates; an engaging portion 54, receding downwardly on the lower surface of the pressure plate 50, for engaging the closure member 20 so that the closure member 20 cut by the cutter 52 can be retained in the outer cap 16; and a locking rib 200 formed between the outer annular surface of the pressure plate 50 and the inner annular surface of the outer cap 16 to maintain the fixed state of the pressure plate 50 relative to the inner annular surface of the outer cap 16 and release the locked state of the pressure plate 50 upon shearing when the pressure plate 50 is pressed .

The pressure plate 50 is located on the upper inner annular surface of the outer cap 16 with a defined gap. The pressure plate 50 is formed in the shape of a disk having a diameter almost similar to the inner diameter of the outer cap 16, and is located on the inner annular surface of the outer cap 16 so that it can move up and down.

The locking rib 200 is placed between the outer annular surface of the pressure plate 50 and the inner annular surface of the outer cap 16 to maintain the locked state of the pressure plate 50 relative to the outer cap 16 and unlock the locked state of the pressure plate 50 relative to the outer cap 16 during shearing when the pressure plate 50 is pressed with force , which exceeds the specified value.

The locking rib 200 is formed as a thin film that can be cut when a predetermined force is applied thereto, and is cut when the pressure plate 50 is pressed with a force exceeding a predetermined amount, thus to guide the pressure plate 50 in downward movement.

Between the outer annular surface of the pressure plate 50 and the inner annular surface of the outer cap 16 with a defined gap, a plurality of guide ribs 202 are formed, which thus guide the pressure plate 50 when moving downwards in a state of connection with the outer cap 16 when the pressure plate 50 moves down

The guide rib 202 is formed in a Z-shaped configuration and has one end mated to the inner annular surface of the outer cap 16 and the other end mated to the outer annular surface of the pressure plate 50. As the pressure plate 50 moves downward, the guide rib 202 elongates, thus , guiding the pressure plate 50 to move down and to maintain the connection state of the pressure plate 50 with the outer cap 16.

The guide rib 202 is inserted into the groove 204 formed in the outer annular surface of the pressure plate 50 and into the groove 206 formed in the inner annular surface of the outer cap 16.

Between the two grooves 204 and 206 and the bent part of the guide rib 202, a connecting strip 208 is formed, which has a small thickness, so that the guide rib 202 maintains a 5-shaped shape.

The connecting tape 208 is cut when the pressure plate 50 moves down.

Between the pressure plate 50 and the outer cap 16, a supporting lifting part 210 is formed to guide the pressure plate 50 to move perpendicularly in the outer cap 16 when the outer cap 16 rotates.

The lifting support part 210 includes at least one guide groove 212 formed perpendicularly on the edge of the lower surface of the outer cap 16 in the downward direction, and at least one guide projection 214 formed on the outer annular surface of the pressure plate 50 and inserted into the guide groove 212 so that it can move along the guide groove 212 up and down.

When the pressure plate 50 moves down, the guide projection 214 formed on the outer annular surface of the pressure plate 50 moves along the guide groove 212 formed on the inner annular surface of the outer cap 16 up and down. Thus, the lifting support part 210 guides the pressure plate 50 to move perpendicularly downward, and transmits the rotational force from the outer cap 16 to the pressure plate 50 when the outer cap 16 rotates, thus rotating the pressure plate 50.

The cutter 54 and the engaging part 54 have a construction and operation principle similar to those indicated above with respect to the first embodiment of the invention, and thus their detailed description will be omitted.

Next, the operation of the child-proof lid according to the fifth embodiment of the present invention will be described.

Figures 25 and 26 are views showing the operation of a childproof cover according to a fifth embodiment of the present invention.

When the pressure plate 50 connected to the outer cap 16 is pushed down by the user to release the contents of the vessel 10 to the outside, the locking rib 200 placed between the pressure plate 50 and the outer cap 16 is cut and the pressure plate 50 moves downward. At this point, the guide rib 202, which has a 5-shaped shape and is placed between the pressure plate 50 and the outer cap 16, is extended, thus, to guide the pressure plate 50 to move down and maintain the mated state of the pressure plate 50 with the outer cap 16.

When the pressure plate 50 moves down, the first cutting parts 62 of the cutters 52 formed on the lower surface of the pressure plate 50 penetrate through the edge of the blocking member 20, and the support rod 66 of the engaging part 54 penetrates through the center of the blocking member 20.

At the moment of penetration through the blocking element 20, the engaging projection 68 of the engaging part 54 is bent upward, thus passing into the hole pierced by the piercing part 70 of the support rod 66. When the engaging projection 68 is located on the inner surface of the blocking element 20, it is elastically transformed to the original state , that is, the extended state.

In this case, when the outer cap 16 is moved down by the user's hand with a force exceeding a certain value, the elastic member 38 is elastically transformed, and the outer cap 16 is moved. As a result, the second engaging protrusion 42 formed on the outer cap 16 is inserted between the first engaging protrusions 40 formed on the inner cap 14, and they engage with each other. In addition, when the outer cap 16 rotates, the rotational force from the outer cap 16 is transmitted to the inner cap 14, and thus the inner cap 14 is separated from the inlet opening 12 of the vessel as it rotates.

At this moment, the rotational force from the outer cap 16 is transmitted to the pressure plate 50 by the lifting portion 210, and thus the pressure plate 50 rotates together with the outer cap 16. When the pressure plate 50 rotates, the cutter 52 rotates in contact with the inner annular surface. of the inlet 12 of the vessel, and the second cutting part 64, formed on both side surfaces of the support part 60, cuts the plugging element 20 of a round shape. As the closure member 20, which has been removed from the vessel inlet 12, is engaged by the engaging projection 68 of the engagement portion 54, it is separated from the vessel inlet 12 together with the inner cap 14, thus remaining in the inner cap 14.

If the contents of the vessel 10, from which the closure element 20 has been removed, is discharged through the vessel inlet 12, and then the cap is re-installed on the vessel inlet 12, the outer cap 16 is moved to the upper side of the inner cap 14 by the spring force of the spring element 38, and the first engagement protrusion 40 is separated from the second engaging protrusion 42. Accordingly, even if the child rotates the outer cap 16, the rotational force from the outer cap 16 is not transmitted to the inner cap 14.

In addition, even if the child moves the outer cap 16 down, due to a weak force, the outer cap 16 does not move down completely due to the elastic force of the elastic member 38. In this state, even if the outer cap 16 rotates, the inclined surface 48 of the second engaging protrusion 42 slides along inclined surface 46 of the first locking protrusion 40 and, thus, the inner cap 14 does not open.

Fig. 27 shows a cross-sectional view of the lid, inaccessible for opening by children, corresponding to the sixth variant of the implementation of this invention.

The childproof cover according to the sixth embodiment of the present invention has the same construction as that of the fifth embodiment of the invention, except for the part that transmits the rotational force

More specifically, the rotational force transmission part 250 according to the sixth embodiment of the present invention includes a first engaging protrusion 252 that is radially located on the upper surface of the inner cap 14 with some gap and extends upward with some width, and a second engaging protrusion 254 that is radially located on the inner surface of the anti-separation protrusion 36, which is formed on the upper inner surface of the outer cap 16 with some gap and passes downward with some width, thus to be locked by the first engaging protrusion 252.

Since the second engaging protrusion 254 is provided with an inclined surface, the first engaging part 252 slides on the inclined surface of the second engaging protrusion 254 when the outer cap 16 rotates. As a result, the rotational force from the outer cap 16 is not transmitted to the inner cap 14. In addition, when the outer cap 16 rotates in the depressed state, the first engaging projection 252 is blocked by the second engaging projection 254, and thus the rotational force from the outer cap 16 is transmitted to the inner cap 14. As a result, the inner cap 14 rotates and the cap is separated from the vessel 10.

Fig. 28 shows a cross-sectional view of the child-proof lid according to the seventh embodiment of the present invention, and Fig. 29 shows a view showing the working state of the child-proof lid according to the seventh embodiment of the present invention.

The child-resistant lid according to the seventh embodiment of the present invention includes an inner cap 14 installed on the inlet 12 of the vessel 10, through which the contents of the vessel are discharged to the outside; the outer cap 16, located on the outer annular surface of the inner cap 14, in such a way that it performs idle rotation relative to the inner cap 14; a rotational force transmission part 18, formed between the inner cap 14 and the outer cap 16, to transmit the rotational force from the outer cap 16 to the inner cap 14 only when the outer cap 16 is moved down with a force that exceeds a certain value; a plugging element removal assembly 22 formed on the inner cap 14 for removing the plugging element 20 hermetically attached to the vessel inlet 12 when the inner cap 14 is separated from the vessel inlet 12 and retaining the removed plugging element 20 in the inner cap 14; and a protective plate 300, movably mounted on the upper surface of the outer cap 16, to protect the closure element removal assembly 22 mounted on the inner cap 14.

The inner cap, the outer cap, and the rotational force transmission part have the same construction as those mentioned above in the first embodiment of the invention, and thus their detailed description will be omitted. As the rotational force transmission part 18, not only the rotational force transmission part 18 mentioned above in the first embodiment of the invention, but also the rotational force transmission part 80 according to the sixth embodiment of the invention can be used.

The protective plate 300 is formed on the upper inner annular surface of the outer cap 16 with some disc-shaped gap. In addition, between the outer annular surface of the protective plate 300 and the upper inner annular surface of the outer cap 16, a connecting part 302 is formed to connect the protective plate 300 to the inner annular surface of the outer cap 16 to guide the protective plate 300 to move up and down and keep of the displaced position of the protective plate 300 by its elastic force.

Between the outer annular surface of the protective plate 300 and the inner annular surface of the inner cap 14, a connecting part 302 is formed in the form of a thin film, which has the shape of a dome. The connecting part 302 is elastically transformed when the protective plate 300 is pressed with a force that exceeds a certain amount, thus guiding the protective plate 300 to move downward.

The connecting part 302 elastically maintains the current position of the protective plate 300. That is, when the protective plate 300 protrudes upward, the connecting part 302 has a convex dome shape and maintains the current state of the protective plate 300. However, when the protective plate 300 is pressed with a force that exceeds a certain value, the connecting part 302 elastically transforms into a concave shape and keeps the protective plate 300 moved down.

The plug removal unit 22 includes a pressure plate 50 mounted on the upper inner annular surface of the inner cap 14 and moved down when the locked state is unlocked when it is pressed with some force; a plurality of cutters 52 formed on the outer edge of the lower surface of the pressure plate 50 in the circumferential direction, for penetrating the closure member 20 when the pressure plate 50 is pressed, and cutting the closure member 20 when the cap rotates; an engaging portion 54 projecting downwardly on the lower surface of the pressure plate 50 to engage the closure member 20 so that the closure member 20 cut by the cutter 52 can be retained in the inner cap 14 and the locking rib 17 placed between the outer annular surface of the pressure plate 50 and the inner ring surface of the inner cap 14, to maintain the locked state of the pressure plate 50 relative to the inner ring surface of the inner cap 14 and unlock the locked state of the pressure plate 50 when it is cut when the pressure plate 50 is pressed.

The plug removal unit 22 according to the seventh embodiment of the invention has the same construction as the plug removal unit 22 according to the fifth embodiment of the invention, except that the pressure plate 50 is connected to the inner annular surface of the inner cap 14, and thus its detailed description will be omitted.

In the childproof cover according to the seventh embodiment of the present invention, when the protective plate 300 is pressed, the connecting part 302 is elastically transformed and thus the protective plate 300 moves down. As a result, the pressure plate 50 located on the lower surface of the protective plate 300 moves downward, thus removing the blocking member 29 and holding the removed blocking member 29 in the inner cap 14. At this point, the blocking member removal assembly 22 has the same principle action as above in the fifth embodiment of the invention, and thus its detailed description will be omitted.

Figure 30 shows a perspective view of a child-resistant cover according to an eighth embodiment of the present invention, and Figure 31 shows a cross-sectional view of a child-resistant cover according to an eighth embodiment of the present invention.

The child-proof cover according to the eighth embodiment of the present invention includes an inner cap 14 mounted on the inlet 12 of the vessel 10, through which the contents of the vessel are discharged to the outside; the outer cap 16, located on the outer annular surface of the inner cap 14, for idling rotation relative to the inner cap 14; part 18 for transmission of rotational force, formed between the inner cap 14 and the outer cap 16, for transmission of rotational force from the outer cap 16 to the inner cap 14 only when the outer cap 16 is moved down by a force that exceeds a certain value; a plugging element removal assembly 22 formed in the inner cap 14 for partial removal of the plugging element 20 when the inner cap 14 is separated from the vessel inlet 12 such that the contents of the vessel can be released little by little, and the removed plugging element 20 can be retained in the inner cap 14.

The inner cap 14 has a cylindrical shape with open upper and lower ends and is equipped with a node 22 for removing the blocking element located in it 22. On the lower inner annular surface of the inner cap 14, an enclosing threaded part 26 is formed, connected along the cut with an enclosing threaded part 24, formed on the outer annular surface of the inlet 12 of the vessel. In addition, from the upper inner annular surface of the encompassing threaded part 26 in the circumferential direction, the glued part 28 recedes for gluing to the upper end of the inlet opening 12 of the vessel. An anti-separation sponge 30 extends from the lower outer annular surface of the inner cap 14 to prevent separation of the inner cap 14 from the outer cap 16.

The outer cap 16 is mounted on the inner cap 14 so that it can move up and down, and has a cylindrical shape with open upper and lower ends. On the upper end of the outer cap 16, an anti-separation protrusion 36 is formed to prevent the inner cap 14 from being separated to the upper side of the outer cap 16. In addition, on the anti-separation protrusion 36, an elastic member 38 is formed, which is supported by the upper surface of the inner cap 14 and supports the displaced state of the outer cap 16 to the upper side of the inner cap 14.

The elastic member 38 has the same construction as the elastic member mentioned above in the third embodiment of the invention, and thus its detailed description will be omitted.

A protective plate 13 is formed on the upper surface of the outer cap to protect the assembly 22 of removing the blocking element formed on the inner cap.

The protective plate 13 has the same construction as the protective plate mentioned above in the third embodiment of the invention, and thus its detailed description will be omitted.

The rotational force transmission part 18 has the same construction as the rotational force transmission part mentioned above in the third embodiment of the invention, and thus its detailed description will be omitted.

The plug removal unit 22 partially removes the plug 20, which is hermetically attached to the inlet opening 12 of the vessel, and holds the removed plug 20 in the inner cap 14. That is, a small hole is formed in the plug 20, as a result of which the contents of the vessel 10 can be released to the outside gradually. When the child drinks the contents of the container 10 in the state when the lid is open, the contents of the container 10 are released little by little and thus the child is protected.

The plug removal unit 22 includes a pressure plate 350 located in the inner cap 14 so that it can move up and down, and is moved down by the protective plate 13 when the protective plate 13 is pressed by the user; a cutter 352 formed near the center of the lower surface of the pressure plate 350 in the circumferential direction with equal intervals to penetrate the closure member 20 when the pressure plate 350 is pressed and partially cut the closure member 20 when the cap rotates; an engagement portion 354 projecting downwardly on the lower surface of the pressure plate 350 to engage the closure member 20 so that the closure member 20 cut by the cutter 352 can be retained in the inner cap 14; and a connecting part 356 formed between the outer annular surface of the pressure plate 350 and the inner annular surface of the inner cap 14 to guide the pressure plate 350 to move up and down and maintain the displaced position of the pressure plate 350 by its elastic force.

The pressure plate 350 is formed in a disc configuration having a diameter smaller than the inner diameter of the inner cap 14.

Fig. 32 shows a perspective view of the cutter unit for removing the sealing element of the lid, inaccessible for opening by children, corresponding to the eighth variant of the implementation of this invention.

As shown in Fig.32, the cutter 352 includes a support part 360 formed on the lower surface of the pressure plate 350 in the circumferential direction with equal intervals, a first pointed cutting part 362 which is formed on the lower end of the support part 360 and moves down when the pressure plate 350 pressed, to penetrate the closure member 20, the second cutting part 364 formed on at least one side surface of both side surfaces of the support part 360, for cutting the closure member 20 in a round shape when the inner cap 14 rotates, and the receiving part 365 in the form of a notch on the front the surface of the support part 360 with some width in the perpendicular direction, to receive the edge of the removed blocking element 20.

As shown in Fig. 33, the engaging part 354 includes a support rod 366 extending from the lower surface of the pressure plate 350 with some length to penetrate through the blocking member 20, and a plurality of engaging protrusions 368 formed on the side surface of the support rod 366 in the circumferential direction, to engage the closure member 20 so that the closure member 20 cut by the cutter 352 can be retained in the inner cap 14.

The support rod 366 is formed as a rod extending downward from the pressure plate 350 , and a pointed piercing portion 370 is formed at the end of the support rod 366 to penetrate the sealing member 20 .

Preferably, the four engaging projections 368 are offset from the peripheral surface of the support rod 366 at an angle of 90".

Between the outer annular surface of the pressure plate 350 and the inner annular surface of the inner cap 14, a connecting part 356 is formed in the form of a thin film, which has the shape of a dome. The connecting part 356 is elastically transformed when the pressure plate 350 is pressed with a force that exceeds a certain amount, thus guiding the pressure plate 350 to move downward.

The connecting part 356 elastically maintains the current position of the pressure plate 350. That is, when the pressure plate 350 protrudes upward, the connecting part 356 has a convex dome and maintains the current state of the pressure plate 350.

However, when the pressure plate 350 is pressed with a force that exceeds a certain value, the connecting part 356 is elastically transformed into a concave shape and maintains the pressed state of the pressure plate 350.

Next, the operation of the child-proof lid according to the present invention will be described.

Figures 34-36 are views showing the working state of the childproof cover according to the eighth embodiment of the present invention.

When the protective plate 13 mated with the outer cap 16 is pushed down by the user to release the contents of the container 10 to the outside, the connecting rib 17 placed between the protective plate 13 and the outer cap 16 is cut and the protective plate 13 moves downward, thus pressing on the pressure plate 50 of the node 22 of removing the blocking element. At this moment, the guide rib 15, which has a 5-shaped shape and is placed between the protective plate 13 and the outer cap 16, is extended, thus to guide the protective plate 13 to move downward and to maintain the mated state of the protective plate 13 with the outer cap 16 .

When the pressure plate 350 is moved down by the protective plate 13, the connecting part 356 is elastically transformed, and the pressure plate 350 moves down. In this case, the first cutting parts 362 of the cutters 352 formed on the lower surface of the pressure plate 350 penetrate through a part of the plugging member 20, and the support rod 366 of the engaging part 354 penetrates through the center of the plugging member 20.

At the moment of penetration through the blocking element 20, the engaging projection 368 of the engaging part 354 is bent upward so that it passes through the hole pierced by the piercing part 370 of the support rod 366. When the engaging projection 368 is located on the inner surface of the blocking element 20, it is elastically transformed into the primary state, i.e. advanced state.

In such a case, when the outer cap 16 is moved down by the user's hand with a force that exceeds a certain value, the elastic member 38 is elastically transformed, and the outer cap 16 is moved. As a result, the second engaging protrusion 42 formed in the outer cap 16 is inserted between the first engaging protrusions 40 formed in the inner cap 14 so that they engage with each other. In addition, when the outer cap 16 rotates, the rotational force from the outer cap 16 is transmitted to the inner cap 14, and thus the inner cap 14 is separated from the inlet opening 12 of the vessel as it rotates.

At this moment, the cutter 352 rotates in a state of contact with the inner annular surface of the vessel inlet 12, and the second cutting part 364 formed on both side surfaces of the support part 360 partially cuts the closure member 20 in a circular shape so as to form an opening 380 in the closure member 20. Since the edge of the plugging element 20, which has been removed from the inlet opening 12 of the vessel, is received in the receiving part 365 formed in the support part 360, and the center of the plugging element 20 is blocked by the engaging projection 368 of the engaging part 354, the plugging element 20 is separated from the input opening 12 vessel together with the inner cap 14 so that it is held in the inner cap 14.

Since the portion of the closure member 20 cut by the closure member removal assembly 22 is a small opening 380, when the child drinks the contents of the container 10 in the state when the lid is open, the contents are slowly released through the opening 380. Accordingly, the amount of content available to the child , decreases, and thus stability can be achieved.

If the contents of the vessel 10, from which the closure member 20 has been removed, is released through the vessel inlet 12, and then the cap is re-installed on the vessel inlet 12, the outer cap 16 is moved to the upper side of the inner cap 14 by the spring force of the spring element 38, and the first the engaging protrusion 40 is separated from the second engaging protrusion 42.

Accordingly, even if the child rotates the outer cap 16, the rotational force from the outer cap 16 will not be transmitted to the inner cap 14.

In addition, even if the child moves down the outer cap 16, due to a weak force, the outer cap 16 does not move down completely due to the elastic force of the elastic member 38. In this state, even if the outer cap 16 rotates, the inclined surface 48 of the second engaging projection 42 slides on the inclined surface 46 of the first locking protrusion 40 and, thus, the inner cap 14 does not open.

Figure 37 shows a cross-sectional view of a child-proof lid according to the ninth embodiment of the present invention.

The cap according to the ninth embodiment of the invention has the same construction as the cap according to the eighth embodiment of the invention, except that the plugging element piercing assembly 400 for piercing the plugging element 20 is formed instead of the plugging element removing assembly 22 of the eighth embodiment variant of the invention.

The child-resistant cover according to the ninth embodiment of the present invention includes: an inner cap 14 installed on the inlet 12 of the vessel 10, through which the contents of the vessel are discharged to the outside; the outer cap 16 is located on the outer annular surface of the inner cap 14 in such a way that it performs idle rotation relative to the inner cap 14; a rotational force transmission part 18, formed between the inner cap 14 and the outer cap 16, to transmit the rotational force from the outer cap 16 to the inner cap 14 only when the outer cap 16 is moved down with a force that exceeds a certain value; and a piercing assembly 400, which is formed in the inner cap 14 and pierces the closure member to produce an opening that has a defined shape to release the contents of the container a little at a time and thus protect the child.

The inner cap 14, the outer cap 16, and the rotational force transmission part 18 have the same construction and operation principle as those mentioned above in the eighth embodiment of the invention, and thus their detailed description will be omitted.

The plug piercing unit 400 includes a pressure plate 402 located in the inner cap 14 so that it can move up and down, and is moved down by the protective plate 13 when the protective plate 13 is pressed, a punch 404 formed in the center of the lower surface of the pressure plate 402 , to form an opening of a predetermined shape in the closure member 20 when the pressure plate 402 is pressed, and a connecting part 406 placed between the outer annular surface of the pressure plate 402 and the inner annular surface of the inner cap 14 to guide the pressure plate 402 to move up and down and maintaining the displaced position of the pressure plate 610 by its elastic force.

The pressure plate 402 is formed in the form of a disk having a diameter smaller than the inner diameter of the inner cap 14.

Figures 38-40 show views that show examples of execution of the punch of a cover that is inaccessible for opening by children, corresponding to the ninth variant of the implementation of this invention.

As shown in Fig. 38, the punch 404 includes a support rod 410, which perpendicularly recedes from the lower surface of the pressure plate 402 and has a defined diameter, and a piercing part 412, which has a conical shape and is formed at the end of the support rod 620 to penetrate through the blocking member 20 and forming a round hole 420.

The punch 404 moves downward when the pressure plate 402 is pressed, thus forming an opening 420 in the closure member 20, whereby the contents of the container 10 can be discharged to the outside through the opening 420.

The purpose of forming the hole 420 in the closure member 20 is to prevent the contents of the container 10 from being released all at once and to release the contents little by little through the hole 420. Accordingly, when a child drinks the contents of the container in a state where the cap is mistakenly opened, a small amount of the contents is available to the child, and thus thus, the child is protected.

The punch 404 can have different shapes corresponding to the type of contents of the vessel 10.

That is, the first punch 404 has a conical shape at its end and is preferably used when the material contained in the vessel 10 is a liquid material such as cooking oil, shampoo, etc., or a liquid material having a certain concentration .

When the material contained in the vessel 10 is a solid material having a certain size, a cross-shaped hole is formed in the plugging member 20 to release the material contained in the vessel 10 to the outside one member at a time. That is, as shown in Fig. 39, the second punch 416 includes a rod part 418, which perpendicularly recedes from the lower surface of the pressure plate 402 and has a cross-shaped cross-section, and a pointed piercing part 422 formed at the end of the rod part 418 to penetrate through the blocking element 20 .

The second punch 416 forms a cross-shaped hole in the closure member 20. Thus, the solid material contained in the container 10, such as a pill, etc., is retained in the hole, thus to be released one by one so that the child can be more safely secured.

As shown in Fig. 40, the third punch 430 is used when the material contained in the vessel 10 is a powdery material, and has a plurality of pins 432 on the lower surface of the pressure plate 402. That is, the third punch 430 is arranged so that the powder that contained in the vessel 10, can be slowly released through a plurality of small holes formed in the closure member 20 when the vessel 10 is shaken.

The punch can have different shapes, corresponding to the type of material contained in the vessel, in addition to the above-mentioned shapes.

The connecting part 406 has the same construction and operation principle as mentioned above in the eighth embodiment of the invention, and thus, its detailed description will be omitted.

Next, the operation of the cover, which is not accessible for opening by children, corresponding to the ninth variant of the implementation of this invention will be described.

Fig.A1 shows a view showing the working state of the childproof lid according to the ninth embodiment of the present invention.

When the protective plate 13 connected to the outer cap 16 is pushed down to release the contents of the container 10 to the outside, the connecting part 17 placed between the protective plate 13 and the outer cap 16 is cut, and the protective plate 13 moves downward, thus pressing on the pressure plate 402 of the unit 22 for removing the blocking element. At this moment, the guide rib 15, which has a 5-shaped shape and is placed between the protective plate 13 and the outer cap 16, is extended, thus to guide the protective plate 13 to move downward and to maintain the mated state of the protective plate 13 with the outer cap 16 .

Then, when the pressure plate 402 is moved down by the protective plate 13, the connecting part 406 is elastically transformed, and the pressure plate 402 moves down. In this case, the punch 404 formed on the lower surface of the pressure plate 402 penetrates through the sealing member 20, thus forming a hole in the sealing member 20.

Upon penetration through the closure member 20, the punch 404 forms an opening 420 having a defined shape in a defined portion of the closure member 20.

Then, when the outer cap 16 is moved down by the user's hand with a force that exceeds a certain value, the elastic member 38 is elastically transformed, and the outer cap 16 is moved. As a result, the second engaging protrusion 42 formed in the outer cap 16 is inserted between the first engaging protrusions 40 formed in the inner cap 14, so as to engage with each other. In addition, when the outer cap 16 rotates, the rotational force from the outer cap 16 is transmitted to the inner cap 14, and thus the inner cap 14 is separated from the inlet opening 12 of the vessel during rotation.

Since the hole 20 is formed in the sealing element 20 by the node 400 piercing the sealing element, the contents of the vessel 10 are slowly released. Accordingly, even if the child drinks the contents of the container 10 by mistake, a small amount of the contents is available to the child and thus the child can be protected.
