Description

Safety opening sealing cover

Technical Field

The present invention relates to a safe opening lid that enables a user to safely open a lid without damaging the user's fingernails and fingers in all cases such as the operation of pulling a can ring to open the lid or the operation of pulling the can ring to open the lid.

Background

Cans called cans are generally used for long-term storage and distribution of food, and are often made of a metal material, and a can lid is provided to open the top of the can when the stored food is taken out.

In order to take out food stored in the can as described above, a finger is hooked on the can ring attached to the can cover in a state where the can ring is pulled up from the can cover, and then the can cover is torn by a motion of pulling up the can ring with a predetermined force.

For example, in a tuna can which is eaten frequently, even if there is no separate tool for removing the can lid, a cut-off line is provided along a peripheral portion of the can lid provided on the can top surface so that the can lid can be removed without another tool by pulling the can ring while pulling the can ring by hooking a finger on the can ring.

At this time, the user pulls up the can ring to open the can lid while holding the outer periphery of the can with one hand and fixing the can, and putting the fingers of the other hand over the can ring.

However, since the can lid is made of a metal material and the can lid is made of a metal material for long-term storage of food, the cut surface of the can lid is only sharp, and thus personal safety accidents frequently occur in which the hand of the user who opens the can lid is cut by the cut surface of the can lid.

(patent document 1) KR10-1479529B

In order to prevent a safety accident from occurring when opening the can lid, patent document 1 proposes a safety lid in which a flat plate covering portion as a component for preventing the occurrence of a safety accident and an opening through which a can ring is exposed to the outside are disclosed.

However, in patent document 1, there is a risk that a user applies a scratch or a nail breakage to the user's nail by performing a lifting operation for rotating the can ring before the user pulls the can ring of the can lid.

In addition, in the above patent document 1, in the process of opening the can lid by pulling the can ring, the sharp edge of the can lid is directly exposed, and there is a high possibility that a wound is generated on the hand or finger of the user.

Disclosure of Invention

The present invention provides a device for protecting the safety of a user when opening a lid of a can for storing food, which can take care of the safety of the user by an operation of pulling a can ring provided on a can lid, a first opening operation of pulling up the pulled can ring by the user, and a second opening operation of continuously pulling up the can ring to completely open the can lid.

In particular, the present invention provides a safe opening cap in which a user presses an upper surface of the safe opening cap downward to closely move the safe opening cap toward a can ring side closely attached to a can lid, and the can ring is gradually pulled up, thereby making it unnecessary to directly pull up the can ring closely attached to the can lid and horizontally placed with a fingernail.

Further, a safe opening lid is proposed, which can prevent a safety accident from occurring due to a lid having a sharp surface during opening by guiding the lid to be bent or curved stably during opening of the lid.

The safety opening closure of the present invention, as a safety opening closure for a can lid of an opening closure can, includes a projecting ring provided in a projecting manner at an upper portion of a can for holding a food; a can lid disposed inside the projecting ring and covering an upper portion of the can; a can ring having one side joined to the can lid, the security open closure comprising: a lid body forming a main body: an outer sidewall extended from an outer circumferential surface of the cover body to a lower side; a can ring lifting part which is arranged on the upper surface of the cover body in a protruding mode according to a specified thickness and is provided with an inclined surface; and a can ring passing tool provided on an upper surface of the cap body, the can ring passing tool forming a space into which the can ring can be inserted when the cap body is pressed downward.

According to the safety opening and closing cap of the present invention, the safety of the user can be ensured by the operation of pulling the can ring provided on the can cover, the first opening operation of pulling the pulled can ring by the user, and the second opening operation of separating the can cover and the can completely to open the can by continuously pulling the can ring.

Further, there is an advantage in that a user does not need to directly lift the can ring with a finger, and thus can prevent the breakage of the nail by lifting the can ring.

Detailed Description

First, the upper side structure of the safety opening cap of the present embodiment will be described with reference to fig. 1 and 2, and the safety opening cap 100 includes: a lid body 101 provided in a shape corresponding to a shape of a lid provided to the can; a cutout 140 provided in the lid body 101; a can ring lifting portion 130 provided in the lid body 101 in a protruding shape with a predetermined thickness; and an outer wall 110 extending downward from the cap body 101 and closely fixed to the outside of the projecting ring 40 of the can 10.

The cap body 101 forms a main body of the safety opening cap, and is provided in a circular shape in the drawing, but if the safety opening cap is applied to a can having a quadrangular shape or a shape other than a quadrangular shape, the shape of the can and the shape of the can lid can be determined.

In general, when opening the can lid 20, the can ring 30 is first erected by a fingernail and then the can ring 30 is pulled to open the can. Therefore, when the can ring 30 is erected, an accident that a fingernail is broken or a finger is cut by the outer circumference of the can lid 20 during opening may occur. To prevent this, a tool is also used to open the seal.

In the present invention, the can ring 30 is inserted into the cut-out portion 140 when food is ingested from the can 10, and the can ring 30 is pulled up as shown in fig. 15, so that the can be safely opened.

In other words, the can ring 30, which is closely attached to and laid flat on the can lid 20, is erected without using other tools and fingernails, and thus an accident of finger cutting is prevented during the opening process, thereby enabling the safe opening of the can lid 20.

Further, by using the safety opening cap 100 at the time of opening, it is possible to protect the nail and prevent the occurrence of a safety accident by a simple operation of inserting the can ring 30 into the catching part 140 to open the cap 20 safely without turning the safety opening cap 100 or other operation, thereby improving the convenience and the effect.

The classification of the structure of the safety cap 100 according to the present invention includes: a component which can be erected while protecting the fingernail when erecting the can ring 30, and a component which can be safely opened while preventing an accident caused by the can lid 20 during the opening process.

The components for protecting the nail and erecting the tank ring 30 include the above-mentioned catching part 140 and the tank ring lifting part 130 provided on the upper surface of the cap body 101.

Further, the components for preventing an accident from occurring in the can lid 20 during the opening process include: the cutout 140; a snap-off cut line 160 and a snap-off cut hole 170 provided in the outer sidewall 110 to be described later with reference to the respective portions; an inner sidewall 120 and a cover hanging piece 121 provided under the cover body 101.

The can ring 30 may be inserted into the cut-out portion 140, or the cut-out portion 140 may be inserted into the can ring 30 after the can ring 30 is erected with a fingernail, and as shown in fig. 12, the can ring 30 may be inserted in a state where the can ring 30 is laid flat in close contact with the can lid 20 in order to protect the fingernail.

First, the cutout 140 and the tank ring lifting portion 130 for lifting up the tank ring 30 while protecting the fingernail will be described in detail.

As described above, the cut-out portion 140 serves as a ring passing tool for exposing the ring 30 to the upper surface of the lid main body 101 by passing the ring 30 closely attached to the lid 20 through the cut-out portion 140 when the lid 20 is opened. As will be described below, the can ring of the present embodiment is provided as the cut-out 140 by a tool, but may be provided as a hole formed in the cap body together with the can ring introduction hole 340 as illustrated in fig. 19 and 20.

The stopper 140 functions to protect the fingernail as a position where the can ring 30 is raised at the time of opening, and to crack the can lid 20 and the can ring 30 which are closely attached when the can ring 30 is raised as shown in fig. 11 to 13; as shown in fig. 15, the standing can ring 30 is pulled up at the time of unsealing and the can ring 30 is prevented from falling down (in the direction of pulling the can ring) from the standing position at the time of unsealing, thereby enabling safe unsealing.

The intercepting part 140 includes: a first cut line 141 corresponding to a portion cut between one side end (edge) of the cap body 101 and the can ring lifting portion 130; and a second cut line 142 provided between the first cut line 141 and one end of the cap body 101, and cut in a direction different from the first cut line 141 in order to increase the opening size of the cap body.

In other words, if it is said that the first cut line 141 is a cut portion along the first direction, the second cut line 142 is a cut portion extended from the first cut line 141 and is a region formed in a direction different from the first direction.

When unsealing, as shown in fig. 11 and 12, the user presses the lid body 101 to the bottom, and positions the cut-out 140 at the bottom of the handle (ring portion) end portion of the can ring 30, so that the lid body 101 is pushed in the axial (rivet) direction of the can ring 30, and the can ring 30 starts to be inserted into the cut-out 140 and cracks with the can lid 20.

Further, as shown in fig. 13, the can ring 30 is gradually ruptured from the can lid 20 by means of the can ring lifting portion 130 while being inserted into the cutout portion 140. When the cap body 101 is pressed to the bottom, the can ring 30 is easily inserted into the cut-out portion 140 so that the cap body 101 is gently lowered, and a first sub cut-out line 143 and a second sub cut-out line 144 for enlarging the width of the first cut-out line 141 and the second cut-out line 142 which are opened together may be further provided.

The first sub-cut line 143 is formed as a cut portion extending from an end of the second cut line 142, and is cut in a direction different from the direction of the second cut line 142. The second sub extraction line 144 is formed to extend from one end of the first sub extraction line 143, and the first sub extraction line 143 and the second sub extraction line 144 are also formed in different extraction directions.

Although the cutting directions are different, a cutting interruption hole 150 for interrupting the cutting is provided at an end of the mutually connected cutting line. By providing the cut-off hole 150, when a portion of the cap body is opened by the cut line, the portion where the cut line is not formed can be prevented from being torn or broken.

In more detail, the ring lifting portion 130 is described in such a manner that a part of the cap body 101 is opened by the cut portion 140, and when the user moves the security open cap 100 toward the ring side, one end portion of the ring is rotated in a direction perpendicular to a direction in which the can lid is opened and a tilting operation is generated.

The can ring lifting portion 130 is formed in a shape protruding with a predetermined thickness on the upper surface of the cap body 101, and a can ring guide ridge 132 for guiding the movement of the introduced can ring 30 is formed protruding on the upper surface of the can ring lifting portion 130.

The tank ring guide ridges 132 guide the moving direction of the tank ring as the contact area of the tank ring with the tank ring lifting portion 130 is gradually increased, for example, a pair of tank ring guide ridges may be provided with a space.

As shown in fig. 3, the cross-sectional shape of the tank ring lifting portion 130 is a shape in which the height gradually increases from one side to the other side, that is, the inclined surface 131 is provided, and thus the introduction area of the tank ring 30 is gradually increased, and the vertical rotation of the tank ring 30 is naturally achieved.

Here, the front side of the opening safety cap may be defined as a region side where the can ring 30 is inserted into the upper surface of the cap body with reference to the center portion of the cap body 101, and the rear side of the opening safety cap may be defined as a position opposite to the front side with reference to the center portion of the cap body 101. That is, the direction in which the ring lifting portion is provided may be defined as the front direction with respect to the center portion of the lid body 101, and the opposite direction may be defined as the rear direction.

In detail, the cut-out portion 140 and the can ring pulling portion 130 are provided at positions eccentric to one side from the center portion of the cap body 101. The cut-out portion 140 is provided at a central portion side of the shaft (rivet) of the can ring 30 in a state where the cap body 101 is coupled to the can protrusion ring 40, and the can ring lifting portion 130 may be provided adjacent to or in contact with the first cut-off line 141 in order to naturally lift up the can ring introduced through the cut-out portion 140, as shown in fig. 1. In this manner, these structures are disposed at positions eccentric in one direction in the center portion of the lid main body 101.

The tank ring pulling portion 130 may be formed in a rectangular shape extending in one direction (longitudinal direction), and the first cut line 141 may be formed in parallel with the longitudinal direction of the tank ring pulling portion 130. The second cut line 142, together with the first cut line 141, functions to expand the open area so that the tank ring 30 can be easily inserted into the upper surface of the cap body 101, and the second cut line 142 has a shape that is continuous in the outward direction from each end of the first cut line 141.

A more detailed description will now be given by way of example of the unsealing process. Fig. 11 to 15 are views illustrating a process of unsealing a can lid using a security open closure according to an embodiment of the present invention.

First, as shown in fig. 11, after separating the security open closure 100 integrated with the can 10 from the can 10, the user presses the upper surface of the closure body 101 while protecting the nails, and starts opening the can lid.

As shown in fig. 12, in order to unseal the lid 20 provided to close the upper portion of the can 10, if the user presses the lid body 101 of the safety opening lid 100 with a finger, a part of the ring lifting portion 130 is lowered to a position lower than the first cut line 141 by the cut portion 140, and a slit for allowing the ring 30 to be inserted into the lid body 101 is formed by the cut portion 140.

Then, if the security open cover 100 is pushed toward the can ring 30, one side of the can ring 30 comes into contact with the can lid 20, and then the security open cover is gradually inserted into the gap of the cutout 140, so that the other side of the can ring 30 is coupled to the can lid 20.

When a part of the end of the ring 30 is inserted into the cut-out portion 140 of the safety opening closure, the user pushes the safety opening closure 100 toward the ring 30 slowly, and at this time, the ring lifting portion 130 provided on the upper surface of the lid body 101 is pushed toward the lower side of the ring 30, and a rotational operation occurs in which the end of the ring 30 is gradually separated from the lid 20 (see fig. 11 to 13).

The can ring 30 is gradually lifted by the can ring lifting part 130, and the fingernails or fingers can be prevented from being injured while the can ring 30 closely attached to the can lid 20 is lifted. That is, as shown in fig. 13, in a state where the can ring 30 is rotated at a predetermined distance from the can lid 20, the lifted can ring 30 can be easily erected with fingers without using nails (see fig. 14).

When the safety opening closure 100 is pushed toward the can ring 30, the outer sidewall 110 is provided with a snap-off cut-off line 160, but the snap-off cut-off line 160 is set at an acute angle, so that the outer sidewall 110 does not catch on the protruding ring 40 or get in the way. The broken intercept line 160 is explained below.

If the user erects the tank ring 30 to a position close to a right angle with respect to the tank lid 20 as shown in fig. 15, the tank ring 30 abuts or contacts (in the case of the embodiment of fig. 17, the position of abutting or contacting the second intercepting line 242) the position of the first intercepting line 141, and if the tank ring 30 is grasped and pulled, the tank ring 30 is supported by the intercepting surface of the first intercepting line 141 (in the case of fig. 17, the intercepting surface of the second intercepting line 242) without falling, and the position of the tank ring 30 is fixed. Therefore, when the can ring 30 is pulled, the can lid 20 is equally fitted into the can body 101 and is simultaneously opened. Therefore, the can lid 20 and the lid main body 101 are neatly bent or folded, and the close contact is improved. Accordingly, the tilting phenomenon between the can lid 20 and the lid body 101 is remarkably reduced, and the can lid 20 is prevented from being exposed to the outside of the lid body 101, thereby being opened safely.

Now, the inner wall 120, the lid hanging piece 121, the fracture cut line 160, and the fracture cut hole 170, which prevent an accident from occurring in opening the can lid 20 by pulling up the can ring 30, will be described in order.

Fig. 4 and 5 show the lower structure of the safety opening closure of the present embodiment.

Fig. 4 and 5 show different embodiments, respectively, and in fig. 5, a cover hanging piece 121 is provided on the inner wall 120.

First, referring to fig. 4, the safety opening closure 100 according to the present embodiment includes the above-mentioned outer sidewall 110 and an inner sidewall 120 disposed inside the outer sidewall 110 in order to be coupled to a protrusion ring 40 (see fig. 12) provided in a general can for keeping food.

The inner wall 120 is provided to prevent the safety opening closure 100 from being suddenly removed from the protruding ring 40 of the can when the can ring 30 is pulled up at the time of unsealing.

The inner wall 120 is extended from the lower surface of the cap body 101 in a planar shape without being bent and has a vertically protruding shape, and is provided on the entire or a part of the lower surface of the cap body 101.

In other words, the inner wall 120 is disposed to be spaced apart from the outer wall 110 by a predetermined distance, and the protruding ring 40 of the can is inserted between the inner wall 120 and the outer wall 110, and the can lid 20 can be inserted into the inner side of the inner wall 120 when unsealing.

If the inner side wall 120 is not formed, the safety tear-open cap 100 is abruptly slid down and off from the can's bulge loop 40 due to the tension of the pull-open can loop 30 when the can loop 30 is pulled to open the can lid 20. In this case, the sharp surface of the can lid is directly exposed, and thus a personal accident occurs (see fig. 15 and 26). Therefore, the inner sidewall 120 is provided to prevent the safety opening cap 100 from being detached from the can 10. That is, when the can lid 20 is opened, the force of pulling the can ring 30 is concentrated behind the lid body 101 located at the opposite position to the front side of the lid body 101 where the can ring 30 is located, and the safety open lid 100 applies the force of pushing and releasing the projecting ring 40 to the rear side. However, the inner wall 120 is caught by the inner surface of the projecting ring 40 to receive resistance, thereby preventing the safety seal from being pushed backward and separated from the can.

In addition, the inner sidewall 120 acts as a wrap during the opening process to prevent the outer perimeter of the sharpened can lid 20 from being exposed. This will be explained below.

In addition, a fracture cut line and a fracture cut hole may be provided in the inner wall 120 at positions corresponding to the fracture cut line or the fracture cut hole formed in the outer wall.

In order to prevent the sharp end of the can lid from being exposed due to deformation of the can lid caused by bending or breaking when the can lid is opened, as shown in fig. 5 and 16, a lid hanging piece 121 formed to protrude with a predetermined thickness may be provided on the inner circumferential surface of the inner wall 120 where the can lid 20 of the can is located during the opening process.

Without the formation of the lid hanging piece 121, the can lid 20 is deformed in a shape that bends or breaks when the can ring 30 is pulled and unsealed, thereby greatly increasing the risk of a safety accident. That is, when the can ring 30 is swung to the left and right and pulled up, if the pulling force is not constant, the lid 20 that is bent or broken is broken far apart at the lower surface of the lid main body 101, and the outer periphery of the lid 20 is exposed and may injure fingers.

However, by providing the lid hanging piece 121 on the inner peripheral surface of the inner wall 120, safety can be ensured in the process of opening the lid 20.

The cover hanging piece 121 may be provided in the sense that the inner sidewall 121 may be vertically protruded and formed from the cover body 101 having a plane form without being bent to the lower side. That is, the inner wall 120 serves as a base which can constitute the cover hanging piece 121. The cover hanging piece 121 will be described in detail.

Fig. 16 shows an underside view of the can lid 20 when the security open closure 100 is used to open the can lid according to an embodiment of the present invention. As shown in fig. 16, the can lid 20 is attached to the inside of the inner wall 120 by touching the lid hanging piece 121 while opening the can lid, and pulling the tension of the can ring 30 to bend or break the lid hanging piece 121 while drawing the can lid 20 below the lid body 101. Accordingly, the outer periphery of the can lid 20 is doubly wrapped by the inner wall 120 and the outer wall 110, and when the can ring 30 is swung left and right to open the can lid in the opening process, the swung can lid 20 is hung on the lid hanging piece 121 even if the force for pulling the can ring 30 is not constant, and thus the can lid 20 is not exposed to the outside or separated from the inner wall 120 and is maintained in the original position. Further, even if the can lid 10 and the can lid 20 are completely separated and opened, the lid hanging piece 121 prevents the can lid 20 from being separated, thereby preventing a safety accident due to the sharp can lid 20.

Fig. 21 to 23 show various shapes of the inner wall 120 constituting the safety seal cover of the present embodiment.

The inner wall 120 shown in fig. 4 and 5 is not provided near the position where the can-ring pulling portion 130 is formed, and the shape of the entire inner wall 120 has a "C" shape.

As shown in fig. 21, according to another embodiment, the entire inner wall 120 may be formed in a circular or elliptical shape, more precisely, in a shape corresponding to the shape of the protruding ring of the can, by a shape corresponding to the outer wall 110 formed along the outer circumferential surface of the cap body 101.

As shown in fig. 22, according to yet another embodiment, in addition to the front portion and the rear portion of the cap body 101, an inner sidewall may be provided in the remaining region, in which case the inner sidewall includes a first inner sidewall 122 provided at one side of the cap body 101 and a second inner sidewall 123 provided at the other side of the cap body 101.

As shown in fig. 23, in yet another embodiment, an inner sidewall may be provided only in a part of the rear direction of the cover body 101, and in this case, the inner sidewall may be provided only in the rear inner sidewall 124.

The outer sidewall 110 may be provided with the above-mentioned snap-off cut line 160, snap-off cut hole 170, and close fitting protrusion 111.

The breaking cut line 160 and the breaking cut opening 170 are provided to prevent an accident from occurring in the can lid 20 and to facilitate opening of the can lid 20, and the contact protrusion 111 is provided to prevent the safety opening lid 100 coupled to the can 10 from easily falling off during the flow.

First, the contact protrusion 111 will be described in detail. As shown in fig. 4, the contact protrusion 111 is protruded to a predetermined thickness from the inner circumferential surface of the outer wall 110, and is closely fixed to the outer side of the protrusion ring 40 of the can.

In this way, the attachment projection 111 prevents the security open closure 100 from easily falling off the can 10 during distribution. The contact protrusion 111 may be provided on the entire inner circumferential surface of the outer wall 110, or may not be provided on a part of the inner circumferential surface.

Fig. 24 is a view showing a lower surface of the security open cover in which the adhesion protrusion 111 of the present invention is formed only on a part of the inner peripheral surface of the outer wall 110.

Unlike fig. 24, when the sticking projection 111 is provided on the entire inner peripheral surface of the outer wall 110 (circular shape), and when the can ring 30 is lifted up at the time of unsealing and then the can ring 30 is pulled up at the initial stage, as shown in fig. 4, the sticking projection 111 provided in a protruding manner is caught on the protruding ring 40 of the can 10, and then the safety opening lid 100 cannot be easily removed from the protruding ring 40, and unsealing becomes difficult. This applies a force to pull the tank ring 30, and the tank ring 30 can be cut.

Therefore, when the direction of the tank ring pulling portion 130 is referred to as the rear direction with reference to the position crossing in the longitudinal direction of the first cut line 141, the inner peripheral surface portion of the outer wall 110 on the front side (the opposite direction of the tank ring pulling portion 130) is not provided with the contact protrusion 111 as shown in fig. 24 (the positions of the first cut line 141 and the tank ring pulling portion 130 are referred to in fig. 1). Therefore, when the can ring 30 is initially pulled up, the security opening closure 100 easily drops from the projecting ring 40 of the can 10, thereby preventing the can ring 30 from being cut.

In other words, the close fitting projection 111 is provided in a "C" shape, or further, a portion may be removed where the cut-off hole 170 is located.

The outer side wall 110 where the cut-off hole 170 is located has the abutting protrusion 111, and due to the thickness of the protruding abutting protrusion 111, an elastic force acting on the outer side wall 110 to be broken and bent is generated when unsealing. Therefore, the portion of the contact protrusion 111 is also removed at the position where the cut-off hole 170 is located, and the elastic force is reduced by the breakage and bending acting on the outer wall 110 at the time of unsealing, thereby facilitating the unsealing.

The above-mentioned broken intercepting line 160 formed at the outer sidewall 110 is explained. As shown in fig. 4 and 15, the break-off cut line 160 is provided on the outer wall 110 in a bilaterally symmetrical manner with respect to the center edge of the lid body 101 that supports the thumb during unsealing.

The breaking cut line 160 is provided to eliminate the elastic force of the outer wall 110 generated during the opening of the can lid 20, to improve the adhesion between the can lid 20 and the lid body 101, and to safely open the can lid 20.

When the safety opening closure 100 is opened without providing the fracture line 160 on the outer sidewall 110, the lid 20 deformed in a shape that is concavely bent or fractured during the opening process and the lid body 101 that is not easily bent or fractured by the elastic force of the outer sidewall 110 cannot be bent or fractured equally. Therefore, when the can lid 20 is opened by shaking the can lid 20 from side to side, the can lid 20 and the lid main body 101 are lifted without maintaining the close contact, and the exposed sharp can lid 20 may injure fingers. However, by forming the break-off cut line 160, the opening can be safely performed.

The outer wall 110 generates elasticity in the unsealing process because the outer wall 110 is formed in a ring shape as shown in fig. 4 and 5, and vertically protrudes downward from the outer circumferential surface of the cap body 101.

Therefore, the snap-off line 160 is provided on the outer wall 110, and when the can ring 30 is pulled at the time of unsealing, the snap-off line 160 provided on the outer wall 110 is naturally completely cut, thereby eliminating the elastic force of the outer wall 110. The elastic force of the outer wall 110 is eliminated, so that the cap body 101 is easily broken, and the cap body 101 and the can lid 20 are equally broken to improve the close contact. Therefore, when the can ring 30 is pulled up by shaking left and right in the opening process, the can lid 20 is not always prevented from being exposed even if the pulling force is not always applied, and the opening can be safely performed (see fig. 15, 16, and 26). For reference, fig. 26 is a partially enlarged view showing a structure in which the inner side wall 120 abuts against the projecting ring 40 of the can when the can ring is pulled up, thereby preventing the safety opening cap from slipping down and separating.

In addition, if the break line 160 is not provided on the outer sidewall 110, the outer sidewall 110 vertically protrudes downward from the cap body 101 in a ring shape, and the outer sidewall 110 is shrunk when the can ring 30 is caught and pulled. Accordingly, if the can ring 30 is pulled up in a state where the safety cap 100 is coupled to the projecting ring 40 of the can 10, the contact protrusion 111 provided to protrude from the inner surface of the outer wall 110 is surely fitted into the projecting ring 40 of the can, and thus the safety cap cannot be easily opened (see the contact protrusion of fig. 4 and 24).

Therefore, although the can ring 30 may be broken when the can ring 30 is pulled up by applying force, if the breaking cut line 160 is provided, the breaking cut line 160 provided in the ring-shaped outer wall 110 is naturally completely cut to eliminate the phenomenon of shrinkage while the can ring 30 is opened. This prevents the can ring 30 from breaking and can be easily opened. It is needless to say that the user can use the cap body 101 by manually completely cutting the break line 160 before unsealing.

As shown in fig. 9 and 10, the breaking/intercepting line 160 may be provided at an acute angle or perpendicular to the cap body 101, and a intercepting/interrupting hole 161 may be provided to prevent additional interception or breakage during the unsealing process. The intercepting interruption holes 161 may be provided and not provided as needed.

The breaking/cutting line 160 is formed by firmly bonding the lid body 101 to the projecting ring 40 of the can 10 in a process of partially cutting and partially opening the opening to flow, and is naturally completely cut when the can ring 30 is pulled in opening.

The outer wall 110 may be provided with one or additional corresponding breakable lines 160 on the left and right sides depending on the size of the can 10, or may be provided with the breakable lines 160 and the breakable holes 170 in parallel as shown in fig. 11 to 15.

In the case where the break-off cut line 160 and the break-off cut hole 170 are provided in parallel, in the case where the center portion of the cap body 101 is indicated by C in the embodiment shown in fig. 8 and 11, if the can ring lifting portion 130 side is defined as the front side and the opposite side is defined as the rear side, the break-off cut hole 170 is provided at a position eccentric to the front side, and the break-off cut line 160 may be conversely provided at a position eccentric to the rear side.

In this way, the break cut hole 170 and the break cut line 160 may be provided in parallel, or only the break cut line 160 may be added without being parallel, so that the break cut line 160 may be provided at all of the front and rear sides, or the break cut hole may be provided at all of the front and rear sides.

In addition, at least one or more fracture-cut lines 160 or at least one or more fracture-cut holes 170, or all of the fracture-cut lines 160 and the fracture-cut holes 170 are provided at corresponding positions on the left and right sides with respect to the tank ring pulling portion 130. For example, the fracture cut hole 170 may be provided on the front side of the cap body 101 with respect to the center portion of the cap body 101, and the fracture cut line 160 may be provided on the rear side of the cap body 101. Conversely, the fracture cut line 160 may be provided on the front side of the cap body 101, and the fracture cut hole 170 may be provided on the rear side of the cap body 101.

The shape of the breaking cut hole 170 may be set in a pattern of four corners, triangle, circle, etc.

As described above, when the breakable cut-off line 160 and the breakable cut-off line 170 are provided in parallel in front of or behind the cap body 101, or the breakable cut-off line 160 or the breakable cut-off line 170 are provided in all of the front and rear directions, as shown in fig. 15, the unsealing process is observed depending on the support position of the thumb supporting the cap body 101.

As shown in fig. 15, when the can ring 30 is pulled to open the lid, the break-off cut line 160 is cut when the support position of the thumb is separated from the rear of the lid body 101, and the elastic force acting on the break-off and bending of the outer wall 110 and the inner wall 120 is weakened, thereby facilitating the opening. Further, when the position of the thumb support is close to the can ring lifting portion 130, the can ring 30 is pulled while the position close to the can ring 30 is pressed by the thumb, and therefore, the opening is difficult, but since the breaking cut hole 170 (hole or groove form) or the breaking cut line 160 can be provided in front of the lid body 101, the elastic force acting on the bending and bending of the outer wall 110 and the inner wall 120 is weakened, and the opening is easy. Therefore, the position where the thumb supports the can lid 20 can be free.

Further, when the can ring 30 is pulled in the opening process, the can lid 20 is bent and curved to deform in shape, the bending and curving of the can lid 20 is realized at the edge of the fracture cut line 160 or the fracture cut hole 170, and the can lid 20 and the lid body 101 are bent or curved equally to improve the close contact.

Accordingly, when the can ring 30 is pulled up by rocking left and right in the unsealing process, the phenomenon of the lift between the can lid 20 and the lid main body 101 is significantly reduced even if the pulling force is not constant, and the unsealing can be performed safely.

At this time, the safe opening lid 100 of the present invention is pressed and slid toward the can ring 30 side, and the fracture cut line 160 and the fracture cut hole 170 are explained in the process of the operation of breaking and lifting the can ring 30 far from the can lid 20.

When the can lid 20 is opened, the opening easiness and safety can be ensured if the snap-off cut line 160 or the snap-off cut line 160 and the snap-off cut hole 170 are provided in parallel on the outer side wall 110.

The angle formed by the break-off cut line 160 and the upper surface of the cap body 101 may be variously changed. However, when the safety opening cap 100 is pressed and slid toward the side of the can ring 30, the breaking line 160 is caught by the projecting ring 40 of the can 10, and the safety opening cap 100 is pushed without being hindered from moving.

Referring to fig. 11 to 13, the breakable cut line 160 is provided in front of the central portion of the cap body 101 (in the direction of the can ring lifting portion 130), and when the safety opening cap 100 is pushed toward the can ring 30 while being pressurized, the gap of the breakable cut line 160 is caught by the projecting ring 40 of the can 10 and becomes an obstacle.

Therefore, a break-open hole 170 formed by a hole or a groove is provided in front of the cap body 101.

The breaking line 160, which is completely cut off when unsealing, is provided on the rear side, and if it is provided vertically as shown in fig. 10, it is caught by the projecting ring 40 of the can 10, and therefore, as shown in fig. 9, it is provided at an acute angle, and the safety unsealing cap 100 can be moved gently toward the can ring 30 side.

As shown in fig. 12, the breaking line 160 is first cut by hand before the opening is started, and then the opening is started by moving the can ring 30 side while pressing the safety opening cap 100, and at this time, the elastic force of the outer wall 110 is weakened, so that the safety opening cap 100 is easily gripped and pressed and moved to the can ring 30 side.

In the case of the security open closure shown in fig. 6 and 7, the provision of the cut line crossing the center of the closure body 101 is intended to facilitate bending or breaking of the closure body when the lid is opened using the security open closure, thereby enhancing the close contact between the closure body 101 and the lid 20 during the opening process.

In other words, the lid body 101 is provided with a lid body breaking cut line 210 for bending the central portion of the lid body 101 when the can lid 20 is opened. The cap body fracture cut line 210 may be provided so as to extend across the edge of the cap body center, so as to be connected to the fracture cut hole 170 and the fracture cut line 160, or may be provided so as not to be connected to the fracture cut hole 170 and the fracture cut line 160. The cap body breaking cut line 210 may be provided in one or additional arrangement according to the size of the can 10, and the cap body breaking cut line 210 may be drawn with a knife or may be provided with a thin thickness.

Referring to fig. 17 and 18, the case where the can ring is provided with the intercept line and the pull-up portion support arm 243 different from the structure of the intercept portion illustrated in the previous embodiment by the tool is illustrated.

In other words, as shown in the drawing, when the user presses the cap body 101 downward, a gap is formed so that the can ring 30 is inserted in front of the can ring pulling portion 130, and when the safety opening cap 100 is pushed toward the can ring 30 and the can ring is inserted, the cut portion 240 for contacting the can ring pulling portion 130 with the lower side of the can ring is provided.

The cut-out portion 240 is provided so as to connect a first cut-out line 241, which cuts out a part of the can ring lifting portion 130 by lowering it when the lid body 101 is pressurized, and a second cut-out line 242; the second cut line 242 is provided at a position spaced apart from the can ring pulling portion 130 by a predetermined interval.

When the lid body 101 is pushed toward the can ring 30 while being pressed downward, a part of the can ring pulling portion 130 is lowered to a position lower than the second cut line 242, the can ring 30 is inserted between the second cut line 242 and the can ring pulling portion 130, and the rotational operation of the one end portion of the can ring 30 being cracked from the can lid 20 is generated by the can ring pulling portion 130.

In the case of embodiment 3, as shown in fig. 17, the tank ring pull portion 130 is provided, so that the tank ring 30 that is far apart from the tank cover 20 can be lifted and unsealed by a finger without a fingernail via the tank ring pull portion 130. As shown in fig. 18, a pulling portion support wall 243 protruding at the same height as the rear portion (the side higher than the inclined surface) of the tank ring pulling portion 130 having the inclined surface 131 may be provided adjacent to or in contact with the tank ring pulling portion 130 at the rear of the tank ring pulling portion 130.

The lifting portion support wall 243 prevents the can ring lifting portion 130 from being lifted up too much when the can ring 30 is lifted and pulled at the time of unsealing.

In other words, when the lid body 101 or the tank ring lifting portion 130 is pressed downward while being pushed toward the tank ring 30, as shown in fig. 18, the first cut line 241 is provided in the tank ring lifting portion 130, and only a part of the tank ring lifting portion 130 is lowered to the lowered position, and the lifting portion support wall 243 is maintained as it is.

When the can ring 30 is pulled up, the lowered can ring pulling portion 130 is raised, and the pulling portion support wall 243 supports the can ring pulling portion 130, thereby preventing the can ring pulling portion 130 from being excessively pulled up.

In the safety cap 100 according to embodiment 4, the can ring pulling portion 130 is provided on the upper surface of the cap body 101 in the same manner, but a tool is provided in front of the can ring pulling portion 130 to insert the can ring 30 into the can ring insertion hole 340 in a size of a can ring.

In fig. 19 and 20, the tank ring introduction hole 340 is provided in a fan shape or even a diamond shape, but may be provided in any pattern such as a rectangular shape, an oval shape, or the like, into which the tank ring 30 is inserted or introduced.

In the case of embodiment 4, if the user presses the cap body 101 downward, the can ring lifting portion 130 is lowered, and if the user pushes the safety opening cap 100 toward the can ring side, the lower surface of the can ring 30 is lifted by the can ring lifting portion 130 while the can ring 30 is inserted through the can ring introducing hole 340, and is rotated.

And, if the raised tank ring 30 is vertically erected with fingers instead of fingernails, the tank ring 30 is abutted or contacted with the tank ring support surface 341.

Therefore, if the erected can ring 30 is pulled at the time of unsealing, the can ring 30 is supported on the can ring support surface 341 and does not fall down, and the position of the can ring 30 is fixed. Therefore, the can lid 20 is opened simultaneously with the lid body 101, and the can lid 20 is bent or folded equally to the lid body 101 during the opening process to improve the close contact, so that the can lid can be opened safely.

As shown in fig. 20, the case of embodiment 4 can also eliminate the outer sidewall 110 that meets the tank ring lead-in 340.

In the upper surface of the security open closure shown in fig. 25, the can ring pulling portion 130 is not provided, but a first cut line 141 and a second cut line 142 as a cut portion 140 of a can ring passing tool, a first sub cut line 143 and a second sub cut line 144, and a cut-off hole 150 are provided.

As described above, the first and second

sub intercept lines

143, 144 and the cut-out 140 together expand the open width. It is possible to easily pressurize the safety cap 100 and insert the can ring 30 into the intercepting part 140.

The safety opening cap 100 thus constructed is used by pushing the safety opening cap 100 toward the can ring 30 while pressing the safety opening cap 100 downward, so that if the can ring 30 is inserted into the slit of the cut-out portion 140, the can ring 30 is erected without using nails or fingers, the can ring 30 is erected after lifting the safety opening cap 100 by hand by placing it on the rear lower surface of the safety opening cap 100, and then the can ring 30 is pulled to open the can.

Of course, the first and second

minor intercepting lines

143 and 144 may be provided as curved lines instead of forming angles, as needed.
