Description

The present invention relates to a safety opening cap that allows a user to safely open a can lid, in any case of an operation of raising a tab to open the can lid or an operation of pulling the tab to open the can lid. We propose a safety opening cap that will not damage the user's nails and fingers.

Generally, for long-term storage and distribution of food and drink, cans, also known as canned foods, are used, and such cans are usually made of metal material, and when the stored food and drink are taken out. A can lid is provided so that the top of the can can be opened.

In order to take out the food and drink stored in such a can, the tab attached to the can lid is raised from the can lid, a finger is hung on the tab, and then the tab is raised with a predetermined force. As a result, the can lid is torn, and at this time, the can lid is provided with a cut portion around the can lid so that it can be easily torn by the action of the tab.

For example, in the case of a tuna can that is often eaten, a cut line is provided along the periphery of the can lid provided on the upper surface of the can so that the can lid can be opened without a separate tool for opening the can lid. This allows the can lid to be opened while the can lid is torn along the cut line by the action of hooking a finger on the tab and pulling the tab, and the can can be opened without a separate tool.

At this time, the user opens the can lid by pulling the tab upward with the finger of the other hand hung on the tab while grasping the outer periphery of the can with one hand and fixing the can.

However, since the material of the can that is used to store food and drink for a long period of time is made of metal, and the can lid is also made of metal, the cut surface of the can lid must be sharp. Frequently, a physical safety accident occurs in which the user's hand for opening the can is cut into the cut surface of the can lid.

In the case of Patent Document 1, a safety cap is proposed to prevent a safety accident when the can lid is opened, and a flat plate cap portion and a tab are exposed to the outside as components for preventing the occurrence of a safety accident. The opening is disclosed.

However, in Patent Document 1, there is a risk that the user's claws may be scratched or the claws may be broken when the user performs a raising operation for rotating the tab before pulling the tab of the can lid.

Further, in Patent Document 1, there is an extremely high possibility that the sharp edge of the can lid is exposed as it is in the process of pulling the tab to open the can lid, causing scratches on the user's hand or finger.

Korean Registered Patent No. 10-1479529

The present invention is a device that can ensure the safety of the user when opening the can lid in which food and drink are stored, and the user raises the tab configured on the can lid and the user raises the raised tab. We propose a device that can give consideration to user safety in both the primary opening operation of pulling and the secondary opening operation of continuously pulling the tab to completely open the can lid.

In particular, in the safety opening cap of the present invention, the tab is gradually raised by the user pressing the upper surface of the safety opening cap downward and moving the safety opening cap to the tab side in close contact with the can lid. By doing so, we propose a safety opening cap that does not require the tab lying in close contact with the can lid to be raised directly by the nail.

Furthermore, we propose a safety opening cap that can guide the can lid to bend or bend stably during the opening process and prevent a safety accident from occurring during the opening process due to the can lid having a sharp surface.

The safety opening cap of the present invention includes a protruding rim formed so as to protrude from the upper part of a can in which food and drink are stored, and a can lid formed inside the protruding rim and covering the upper part of the can. In a can including a tab whose one side is connected to the can lid, it is a safety opening cap for opening the can lid of the can, and the cap body forming the main body and the outer peripheral surface of the cap body to the lower side. The outer wall that extends, the tab raising portion that is formed so as to project to a predetermined thickness from the upper surface of the cap body, and the tab raising portion that has an inclined surface, and the upper surface of the cap body are formed, and the cap body is lowered. Includes tab passage means to form a space into which the tab can be inserted when pressurized to the side.

With the safety opening cap of the present invention, the operation of raising the tab configured on the can lid, the primary opening operation of pulling the raised tab by the user, and the continuous pulling of the tab to completely separate the can lid from the can and open it. It is possible to guarantee the safety of the user in any of the secondary opening operations.

In addition, since the user does not have to directly raise the tab with the nail, there is an advantage that the nail can be prevented from breaking when the tab is raised.

1 to 4 are views showing the configuration of a safety opening cap according to the first embodiment of the present invention.

First, with reference to FIGS. 1 and 2, the configuration of the upper side of the safety opening cap of this embodiment will be described. The safety opening cap 100 is a cap body having a shape corresponding to the shape of the can lid configured on the can. 101, a cutout portion 140 formed in the cap body 101, a tab raising portion 130 having a shape protruding from the cap body 101 to a predetermined thickness, and extending downward from the cap body 101. Includes an outer wall 110 that is formed and closely fixed to the outside of the protruding rim 40 of the can 10.

The cap body 101 has a configuration that forms the main body of the safety opening cap and has a circular shape in the drawing. However, if the safety opening cap is applied to a can having a square shape or other shape, the cap body 101 may be formed. The pattern can be determined to correspond to the shape of the can or the shape of the can lid.

Generally, when opening the can lid 20, the tab 30 is first raised with a nail, and then the tab 30 is pulled to open the can lid 20. Therefore, when the tab 30 is caused, the nail may be broken, or a finger may be cut on the outer circumference of the can lid 20 during the opening process. In some cases, a tool is used to open the package to prevent this.

In the present invention, the tab 30 is integrally combined with the can 10 and stored in a distribution manner, and when the food and drink of the can 10 is ingested, the tab 30 is sandwiched between the cutout portions 140 as shown in FIG. 15, and then the tab 30 is pulled. It allows you to open the package safely.

That is, the tab 30 lying in close contact with the can lid 20 can be raised without using a nail without the need for other tools, and the can can be safely prevented from being cut by a finger during the opening process. Allow the lid 20 to be opened.

Further, by using the safety opening cap 100 at the time of opening, the claws are protected by a simple operation of inserting the tab 30 into the cutout portion 140 and opening the tab 30 without a separate operation such as repeating the safety opening cap 100. The can lid 20 can be opened safely by preventing a safety accident on the finger and improving convenience and effectiveness.

The constitutional classification of the safety opening cap 100 of the present invention includes a component portion that can be raised while protecting the nail when the tab 30 is caused, and a portion that can be safely opened by preventing an accident caused by the can lid 20 in the opening process. Consists of.

The components that can cause the tab 30 while protecting the nails include the cutout portion 140 and the tab raising portion 130 formed on the upper surface of the cap body 101 mentioned above.

The components for preventing an accident caused by the can lid 20 in the opening process are the cutout portion 140, the refraction cut line 160 and the refraction cut hole 170 formed in the outer wall 110 described below for each part, and the refraction cutout hole 170. There is an inner side wall 120 formed on the lower surface of the cap body 101 and a lid hook piece 121.

Inserting the tab 30 into the cutting portion 140 can also cause the cutting portion 140 to be inserted into the tab 30 after raising the tab 30 with a nail, in order to cause the tab 30 while protecting the nail. As shown in FIG. 12, the tab 30 can be inserted in a state of being in close contact with the can lid 20 and lying down.

First, the cutout portion 140 and the tab raising portion 130 that cause the tab 30 while protecting the nails will be described in detail.

As mentioned above, when the can lid 20 is opened, the cut portion 140 allows the tab 30 in close contact with the can lid 20 to pass through the cut portion 140 and is placed on the upper surface of the cap body 101. It is a means of passing through tabs for exposure. As will be described below, the tab passing means in this embodiment is configured as the cutout portion 140, or is a hole formed in the cap body as in the tab inflow hole 340 exemplified in FIGS. 19 and 20. Can be configured as.

The cutout portion 140 is a position where the tab 30 is raised at the time of opening, and when the tab 30 is raised while protecting the nail as shown in FIGS. 11 to 13, the can lid 20 and the tab 30 are brought into close contact with each other. A function that allows a gap to be created when the tab 30 is opened, and as shown in FIG. 15, when the tab 30 is pulled and opened, the tab 30 is pushed downward (in the direction of pulling the tab) from the raised position. It functions as a support to prevent it from being lowered so that it can be opened safely.

The cut portion 140 includes a first cut line 141 corresponding to a portion cut between one side end portion (edge) of the cap body 101 and the tab raising portion 130, the first cut line 141, and the cap body 101. Includes a second cut line 142 that is formed between one side end and cut in a different direction than the first cut line 141 to increase the open size of the cap body.

That is, if the first cut line 141 is a portion cut in the first direction, the second cut line 142 is a cut portion extending from the first cut line 141, but is cut in a direction different from the first direction. Can be the region where is formed.

At the time of opening, as shown in FIGS. 11 and 12, the user keeps the cut portion 140 under the handle (loop portion) end of the tab 30 while pressing the cap body 101 downward, and the cap When the body 101 is pushed and moved in the tab 30 axis (rivet) direction, a gap is formed between the tab 30 and the can lid 20 while the tab 30 begins to be inserted into the cutout portion 140.

Further, as shown in FIG. 13, the tab 30 is gradually expanded from the can lid 20 by the tab raising portion 130 while being inserted into the cutting portion 140. When the cap body 101 is pressed downward, the first cut line 141 and the second cut line 141 and the second cut line so that the cap body 101 is smoothly lowered and the tab 30 is easily inserted into the cut portion 140. A first sub-cut line 143 and a second sub-cut line 144 for expanding the width opened with 142 may be further formed.

The first sub-cutting line 143 is a cutting portion extending from the end of the second cutting line 142, and is formed so as to be cut in a direction different from that of the second cutting line 142. The second sub-cutting line 144 is formed in a shape extending from one side end of the first sub-cutting line 143, and the first sub-cutting line 143 and the second sub-cutting line 144 are also cut in different directions. Can be configured in.

Then, although the cutting direction is different, a cutting cutting hole 150 is formed at the end of the cut lines that are interconnected so that the cutting is cut. By forming the cut-off hole 150, it is possible to prevent the cap body from being torn or damaged to a region where the cut-off line is not formed when a part of the cap body is opened by the cut-off line.

On the other hand, when a part of the cap body 101 is opened by the cutout portion 140 and the user moves the safety opening cap 100 to the tab side, one side end of the tab is in the vertical direction corresponding to the direction extending from the can lid. A more detailed consideration will be given to the tab raising portion 130 for causing the lifting operation while rotating.

The tab raising portion 130 has a shape protruding from the upper surface of the cap body 101 to a predetermined thickness, and guides the movement of the tab 30 flowing into the upper surface of the tab raising portion 130. The tab guide step 132 is formed so as to project.

The tab guide step 132 is for guiding the moving direction as the area in which the tab contacts the tab raising portion 130 gradually increases. For example, a pair of tab guide steps are spaced apart from each other. Can be formed.

Then, as shown in FIG. 3, the tab raising portion 130 has a shape in which the height gradually increases as the cross-sectional shape moves from one side to the other side, that is, an inclined surface 131. As the inflow area of the tab 30 gradually increases depending on the shape, the tab 30 naturally rotates in the vertical direction.

Here, the front of the safety opening cap can be defined as the region side where the tab 30 of the can is inserted into the upper surface of the cap body with reference to the central portion of the cap body 101, and the rear of the safety opening cap is described above. The position can be defined as the position opposite to the front with respect to the central portion of the cap body 101. That is, with respect to the central portion of the cap body 101, the direction in which the tab raising portion is formed can be defined as the front, and the opposite direction can be defined as the rear.

In detail, the cut portion 140 and the tab raising portion 130 are configured at positions eccentric to a certain side from the central portion of the cap body 101. The cutout portion 140 is formed on the central portion side of the tab 30 axis (rivet) when viewed from the state where the cap body 101 is coupled to the protruding rim 40 of the can, and the tab raising portion 130 is the cutout portion 130. The tabs coming in through the portion 140 may be adjacent to or in contact with the first cut line 141, as shown in FIG. As described above, these configurations are arranged at positions eccentric in the unilateral direction from the central portion of the cap body 101.

The tab raising portion 130 may be formed in a rectangular shape extending in one direction (longitudinal direction), and the first cutting line 141 may be formed in parallel with the longitudinal direction of the tab raising portion 130. Good. Further, the second cut line 142, together with the first cut line 141, serves to expand the open area so that the tab 30 can be easily inserted into the upper surface of the cap body 101, and the first cut line 142 serves as the first cut line. It has a shape connected outward from each end of 141.

Here, the opening process will be described in more detail by way of examples. 11 to 15 are views showing a process of opening a can lid using a safety opening cap according to an embodiment of the present invention.

First, as shown in FIG. 11, after separating the safety opening cap 100 integrally connected to the can 10 and then pressing the upper surface of the cap body 101 while protecting the claws, the user can press the can lid. Opening begins.

As shown in FIG. 12, when the user presses the cap body 101 of the safety opening cap 100 with a finger in order to open the can lid 20 provided for sealing the upper portion of the can 10, the cutout portion is formed. A part of the tab raising portion 130 is lowered to a position lower than the first cutting line 141 by 140, and a gap is formed in the cap body 101 by which the tab 30 can be inserted by the cutting portion 140.

Then, when the safety opening cap 100 is pushed toward the tab 30, the tab 30 is gradually inserted into the gap of the cutout 140 from the state where one side of the tab 30 is in contact with the can lid 20, and the other side of the tab 30 is connected to the can lid 20. Become.

When a part of the end portion of the tab 30 is inserted into the cut portion 140 of the safety opening cap 100, the user gradually pushes the safety opening cap 100 toward the tab 30 side, and at this time, the upper part of the cap body 101. While the tab raising portion 130 formed on the surface is pushed into the lower side of the tab 30, one side end of the tab 30 gradually expands away from the can lid 20 (see FIGS. 11 to 13).

The tab 30 is gradually lifted by the tab raising portion 130, and it is possible to prevent the nails and fingers from being injured while causing the tab 30 in close contact with the can lid 20. That is, as shown in FIG. 13, when the tab 30 is rotated so as to be separated from the can lid 20 by a predetermined distance, the raised tab 30 can be easily raised vertically with a finger without using a claw. Can be done (see FIG. 14).

When the safety opening cap 100 is pushed into the tab 30 side, the refraction cut line 160 is formed on the outer wall 110, but the outer wall 110 is caught by the protruding rim 40 because the refraction cut line 160 has an acute angle. It will not be disturbed or disturbed. The refraction cut line 160 will be described below.

When the user raises the tab 30 close to a right angle to the can lid 20 as shown in FIG. 14, the tab 30 is adjacent to or in contact with the position of the first cutting line 141 as shown in FIG. 15 (in the embodiment of FIG. 17). (In this case, it is adjacent to or in contact with the position of the second cutting line 242), and when the tab 30 is pulled, the tab 30 is cut from the cut surface of the first cutting line 141 (in the case of FIG. 17, the second cutting line 242 is cut). The position of the tab 30 is fixed without being pushed down by being supported by the surface). Therefore, when the tab 30 is raised, the can lid 20 and the cap body 101 are both equally bent and opened together. Therefore, the can lid 20 and the cap body 101 are bent or bent in parallel to improve the adhesion. As a result, the phenomenon of floating between the can lid 20 and the cap body 101 is remarkably reduced, and the can lid 20 can be prevented from being exposed to the outside of the cap body 101 and can be safely opened.

Next, the inner side wall 120, the lid hook piece 121, the refraction cut line 160, and the refraction incision hole 170, which prevent an accident due to the can lid 20 in the process of raising the tab 30 and opening the can lid 20, will be sequentially described.

4 and 5 show the lower configuration of the safety opening cap of this embodiment.

4 and 5 show other embodiments, respectively, and in the case of FIG. 5, the lid hook piece 121 is formed on the inner side wall 120.

First, referring to FIG. 4, the safety opening cap 100 of this embodiment is mentioned above in order to be coupled with a protruding rim 40 (see FIG. 12) normally formed in a can for storing food and drink. The outer side wall 110 and the inner side wall 120 formed inside the outer wall 110 are included.

The inner side wall 120 is formed to prevent the safety opening cap 100 from being suddenly detached from the protruding rim 40 of the can when the tab 30 is raised at the time of opening.

The inner side wall 120 is formed on the entire or part of the lower surface of the cap body 101 while having a shape extending vertically from the lower surface of the cap body 101 which is flat without bending. ..

That is, the inner wall surface 120 is arranged so as to be separated from the outer wall surface 110 by a predetermined distance so that the protruding rim 40 of the can is inserted between the inner wall surface 120 and the outer wall 110. At the time of opening, the can lid 20 is inserted inside the inner side wall 120 so that the can lid 20 can enter.

If the inner side wall 120 is not formed, when the tab 30 is pulled at the time of opening to open the can lid 20, the safety opening cap 100 suddenly slides away from the protruding rim 40 of the can due to the tension of pulling the tab 30. Will be done. As a result, the sharp surface of the can lid is exposed as it is, causing an accident to the body (see FIGS. 15 and 26). Therefore, the inner side wall 120 is formed so as to prevent the safety opening cap 100 from coming off from the can 10. That is, when the can lid 20 is opened, the force for pulling the tab 30 is concentrated on the rear side of the cap body 101, which is opposite to the front side of the cap body 101 on which the tab 30 is located, and the safe opening cap 100 is described above. A force is applied that is pushed backward of the protruding rim 40 and released. However, since the inner side wall 120 is caught on the inner side surface of the protruding rim 40 and receives resistance, it is possible to prevent the safety opening cap from being pushed backward and being separated from the can.

Further, the inner side wall 120 serves to wrap the sharp can lid 20 so that the outer circumference of the can lid 20 is not exposed during the opening process. This will be described below.

Then, the refraction cut line and the refraction incision hole may be formed on the inner side wall 120 at a position corresponding to the refraction cut line or the refraction incision hole formed on the outer wall.

The can lid 20 of the can during the opening process, as shown in FIGS. 5 and 16, in order to prevent the sharp end of the can lid from being exposed due to the bending or bending shape deformation of the can lid when the can lid is opened. A lid hooking piece 121 formed so as to project to a predetermined thickness on the inner peripheral surface of the inner wall surface 120 in which the is located may also be formed.

If the lid hook piece 121 is not formed, when the tab 30 is pulled to open the can lid 20, the can lid 20 is bent or the shape is deformed to be refracted, and the risk of a safety accident becomes extremely high. That is, when the tab 30 is swayed from side to side and pulled, if the pulling force is not constant, the outer circumference of the can lid 20 in which the bent or refracted can lid 20 spreads away from the lower surface of the cap body 101 is exposed. May hurt your fingers.

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

The lid hook piece 121 can be formed because the inner side wall 120 is formed so as to vertically project downward from the cap body 101 having a flat shape without bending. That is, the inner side wall 120 serves as a base that can form the lid hooking piece 121. The lid hook piece 121 will be described in detail.

FIG. 16 shows a pattern on the lower surface when the can lid 20 is opened using the safety opening cap 100 according to the embodiment of the present invention. As shown in FIG. 16, the can lid 20 reaches the lid hook piece 121 while being opened, and the can lid 20 enters the lower surface of the cap body 101 while the lid hook piece 121 is bent and refracted by the tension pulling the tab 30. It will come and settle inside the inner side wall 120. As a result, the inner side wall 120 and the outer wall 110 double wrap the outer circumference of the can lid 20, and when the tab 30 is shaken left and right during the opening process to open the can, the tab 30 is shaken even if the pulling force is not constant. Since the can lid 20 is hooked on the lid hook piece 121, the position of the can lid 20 is maintained without being exposed or detached from the inner side wall 120. Further, even if the can 10 and the can lid 20 are completely separated and opened, the lid hook piece 121 can prevent the can lid 20 from coming off, and a safety accident due to the sharp can lid 20 can be prevented.

21 to 23 are views showing various shapes of the inner side wall 120 constituting the safety opening cap of this embodiment.

In the shape of the inner side wall 120 shown in FIGS. 4 and 5, since the inner side wall is not formed near the position where the tab raising portion 130 is formed, the shape of the inner side wall 120 as a whole has a “C” shape. Have.

In another embodiment, as shown in FIG. 21, the shape corresponds to the outer wall 110 formed along the outer peripheral surface of the cap body 101, and the inner side wall 120 has a circular or elliptical shape as a whole. It can consist of a shape, or more precisely a shape that corresponds to the shape of the protruding rim of the can.

Further, in another embodiment, as shown in FIG. 22, an inner side wall may be formed in the remaining region except for a part in the front direction and a part in the rear direction of the cap body 101, in which case the inner side wall is formed. The wall includes a first inner side wall 122 formed on one side of the cap body 101 and a second inner side wall 123 formed on the other side of the cap body 101.

Further, in another embodiment, as shown in FIG. 23, the inner side wall may be formed only in a part in the rear direction of the cap body 101, and in this case, only the rear inner side wall 124 is formed as the inner side wall. It can be the case.

The outer wall 110 may be formed with the refraction cut line 160, the refraction incision hole 170, and the close contact projection 111 mentioned above.

The refraction cut line 160 and the refraction incision hole 170 are formed so as to prevent an accident due to the can lid 20 and to facilitate opening when the can lid 20 is opened, and the close contact protrusion 111 is formed during the distribution process. It is formed to prevent the safety opening cap 100 bonded to the can 10 from being easily removed.

First, the close contact projection 111 will be described in detail. As shown in FIG. 4, the close contact protrusion 111 is formed so as to project on the inner peripheral surface of the outer wall 110 to a predetermined thickness, and is closely attached to and fixed to the outside of the protruding rim 40 of the can.

By forming the close contact protrusion 111 in this way, it is possible to prevent the safety opening cap 100 from being easily removed from the can 10 during the distribution process. The close contact projection 111 may be formed on the entire inner peripheral surface of the outer wall 110, or may not be formed on a part thereof.

FIG. 24 is a view of the lower surface of the safety opening cap showing that the close contact projection 111 of the present invention is formed only on a part of the inner peripheral surface of the outer wall 110.

When the close contact protrusion 111 is formed on the entire inner peripheral surface of the outer wall 110 unlike FIG. 24 (circular shape), when the tab 30 is raised at the time of opening and then the tab 30 is initially pulled, FIG. As described above, the protruding contact protrusion 111 is caught by the protruding rim 40 of the can 10, and the safety opening cap 100 cannot be easily removed from the protruding rim 40, which makes opening difficult. As a result, the tab 30 may be cut by forcing the tab 30 to be pulled.

Therefore, when the direction of the tab raising portion 130 is rearward with respect to the position crossing the first cutting line 141 in the longitudinal direction, the inner peripheral surface portion of the outer wall 110 on the front side (opposite direction of the tab raising portion 130) is The close contact projection 111 is not formed as shown in FIG. 24 (see FIG. 1 for the positions of the first cutting line 141 and the tab raising portion 130). Then, when the tab 30 is initially pulled, the safety opening cap 100 is easily disengaged from the protruding rim 40 of the can 10 to prevent the tab 30 from being cut.

That is, the close contact projection 111 can be made into a "C" shape, or a part of the refraction incision hole 170 can be removed at the position.

If the outer wall 110 where the refraction incision hole 170 is located has the close contact protrusion 111, a repulsive force is generated in the bending and bending action of the outer wall 110 at the time of opening due to the thickness of the protruding close contact protrusion 111. Therefore, the close contact projection 111 is partially removed also at the place where the refraction incision hole 170 is located, and the repulsive force is reduced due to the bending and bending action of the outer wall 110 at the time of opening, so that the opening is facilitated.

The refraction cut line 160 formed on the outer wall 110 mentioned above will be described. As shown in FIGS. 4 and 15, the refraction cut line 160 is formed on the outer wall 110 symmetrically from the periphery of the central portion of the cap body 101 that supports the thumb when opened.

The refraction cut line 160 is formed by eliminating the repulsive force of the outer wall 110 generated in the opening process of the can lid 20 and improving the adhesion between the can lid 20 and the cap body 101, which is safe. Is formed to open the can lid 20.

When the safety opening cap 100 is opened without forming the refraction cut line 160 on the outer wall 110, the repulsive force of the outer wall 110 and the can lid 20 which is dented and bent while being bent during the opening process and deformed in shape. The cap body 101, which is not easy to bend and refract, does not bend or bend equally. Therefore, when the can lid 20 is opened while being shaken from side to side, the can lid 20 and the cap body 101 float up without maintaining the adhesion, and an accident occurs in which the exposed sharp can lid 20 damages a finger. obtain. However, it can be safely opened by forming the refraction cut line 160.

The reason why the outer wall 110 generates a repulsive force in the opening process is that the shape of the outer wall 110 is vertically projected downward from the outer peripheral surface of the cap body 101 in a ring (loop) shape as shown in FIGS. 4 and 5. This is because of the fact.

Therefore, the refraction cut line 160 is formed on the outer wall 110, and the repulsive force of the outer wall 110 is made so that the refraction cut line 160 formed on the outer wall 110 is naturally completely incised when the tab 30 is pulled at the time of opening. Make it disappear. As a result, the repulsive force of the outer wall 110 is extinguished and the cap body 101 is easily bent, and the cap body 101 and the can lid 20 are bent equally to improve the adhesion. Therefore, when the tab 30 is swayed from side to side and pulled during the opening process, the can lid 20 is prevented from being exposed and the can lid 20 can be safely opened even if the pulling force is not constant (see FIGS. 15, 16 and 26). .. For reference, FIG. 26 shows a partially enlarged view of the configuration in which the inner side wall 120 is brought into close contact with the protruding rim 40 of the can when the tab is pulled to prevent the safety opening cap from sliding and detaching downward. Has been done.

Further, if the refraction cut line 160 is not formed on the outer wall 110, the outer wall 110 is vertically projected downward from the cap body 101 in a ring (loop) shape, and the outer wall 110 is pulled when the tab 30 is pulled. Shrinks. As a result, when the tab 30 is pulled while the safety opening cap 100 is connected to the protruding rim 40 of the can 10, the close contact protrusion 111 formed so as to protrude on the inner surface of the outer wall 110 fits snugly on the protruding rim 40 of the can. , It becomes difficult to open the package (see the close contact protrusions in FIGS. 4 and 24).

Therefore, if the tab 30 is pulled with too much force, the tab 30 may be cut. However, if the refraction cut line 160 is configured, the tab 30 is opened when the tab 30 is pulled, and the outer side is in the shape of a ring (loop). The phenomenon that the refraction cut line 160 formed on the wall 110 naturally becomes a complete incision and shrinks disappears. As a result, the tab 30 can be easily opened while being prevented from being cut. Of course, it is natural that the user can artificially completely incise the refraction cutting line 160 before opening the cap body 101.

The refraction cut line 160 can be formed at an acute angle or vertically from the cap body 101, as shown in FIGS. 9 and 10, and additional cut and breakage may occur when the cut is made during the opening process. A cut break hole 161 may be formed to prevent the above. The cut-off hole 161 may or may not be formed as needed.

The refraction cut line 160 is partially incised and partially incised so that the cap body 101 is firmly connected to the protruding rim 40 of the can 10 in the distribution process, and when the tab 30 is pulled at the time of opening, the cap body 101 is naturally completely incised. To be.

The outer wall 110 can be formed with one or more refraction cut lines 160 corresponding to the left and right depending on the size of the can 10, or as shown in FIGS. 11 to 15, refraction with the refraction cut lines 160. The incision holes 170 can be formed in parallel.

The position formed when the refraction cut line 160 and the refraction incision hole 170 are formed in parallel is tabbed when the central portion of the cap body 101 is indicated as C as shown in FIGS. 8 and 11 as an example. If the raised portion 130 side is defined as the front side and the opposite side is defined as the rear side, the refraction incision hole 170 is formed at a position eccentric to the front side, and the refraction cut line 160 is conversely eccentric to the rear side. Can be formed in a position.

In this way, the refraction incision hole 170 and the refraction cut line 160 can be formed in parallel, or only the refraction cut line 160 is added in parallel and formed in the refraction cut line 160 both forward and backward, or forward. Both and posterior can form a refraction incision.

More specifically, based on the tab raising portion 130, at least one or more refraction cut lines 160 or at least one or more refraction incision holes 170 are formed at positions corresponding to the left and right sides, or the above. Both the refraction cut line 160 and the refraction incision hole 170 can be formed. For example, the refraction incision hole 170 may be formed on the front side of the cap body 101 and the refraction cut line 160 may be formed on the rear side of the cap body 101 based on the central portion of the cap body 101. On the contrary, the refraction cut line 160 may be formed on the front side of the cap body 101, and the refraction incision hole 170 may be formed on the rear side of the cap body 101.

The shape of the refraction incision hole 170 may consist of a pattern such as a square, a triangle, and a circle.

As described above, when the refraction cut line 170 and the refraction cut line 160 are formed in parallel in the front and the rear of the cap body 101, or when the refraction cut line 160 or the refraction cut line 170 is formed both in the front and the back. , As shown in FIG. 15, the opening process by the support position of the thumb supporting the cap body 101 will be considered.

When the position where the thumb is supported when pulling the tab 30 at the time of opening is performed away from the rear of the cap body 101 as shown in FIG. 15, the refraction cutting line 160 becomes an incision and the outer wall 110 and the inner side wall 120 are bent and The repulsive force is weakened by the bending action, and the opening becomes easier. When the position where the thumb is supported is close to the tab raising portion 130, it is difficult to open the tab 30 because the tab 30 is pulled while pressing the position close to the tab 30 with the thumb, but the front of the cap body 101 Since the refraction cut hole 170 (hole or groove form) or the refraction cut line 160 can be formed in the outer wall 110 and the inner side wall 120, the repulsive force of the bending and bending action is weakened and the opening is facilitated. Therefore, the position where the thumb supports the can lid 20 can be freely set.

Further, when the tab 30 is pulled in the opening process, the can lid 20 is bent and bent to form a shape deformation, but the can lid 20 is bent and bent around the refraction cut line 160 or the refraction incision hole 170, and the can lid 20 is bent and bent. 20 and the cap body 101 are equally bent or bent to improve adhesion.

As a result, when the tab 30 is swayed from side to side and pulled during the opening process, the phenomenon of lifting between the can lid 20 and the cap body 101 is significantly reduced even if the pulling force is not constant, and the opening can be safely performed. ..

Next, the refraction cutting line 160 and the refraction in the process of the operation in which the safety opening cap 100 of the present invention is pushed into the tab 30 side while being pressed and moved so that the tab 30 spreads away from the can lid 20. The incision hole 170 will be described.

When the can lid 20 is opened, if the refraction cut line 160 or the refraction cut line 160 and the refraction incision hole 170 are formed in parallel on the outer wall 110, the ease and safety of opening can be ensured.

The angle between the refraction cut line 160 and the upper surface of the cap body 101 can be changed in various ways. However, when the safety opening cap 100 is pushed into the tab 30 side while being pressed and moved, the refraction cut line 160 is not caught by the protruding rim 40 of the can 10 and does not interfere with the movement while pushing the safety opening cap 100. To.

Explaining with reference to FIGS. 11 to 13, if the refraction cut line 160 is formed in the front (direction toward the tab raising portion 130 side) from the central portion of the cap body 101, the tab while pressurizing the safety opening cap 100. When it is pushed to the 30 side and moved, the gap of the refraction cutting line 160 is caught by the protruding rim 40 of the can 10 and hinders it.

Therefore, a refraction incision hole 170 formed of a hole or a groove is formed in front of the cap body 101.

Further, although the refraction cutting line 160 that makes a complete incision at the time of opening is formed at the rear, if it is formed vertically as shown in FIG. 10, it will be caught by the protruding rim 40 of the can 10, so that it is as shown in FIG. In addition, the safety opening cap 100 is formed at an acute angle so that the safety opening cap 100 can be smoothly moved to the tab 30 side.

Of course, as shown in FIG. 12, before starting the opening, the refraction cutting line 160 can be opened by hand, and then the safety opening cap 100 can be moved to the tab 30 side while being pressurized to start the opening. In this case, since the repulsive force of the outer wall 110 is weakened, it becomes easy to grip and pressurize the safety opening cap 100 and push it toward the tab 30 to move it.

6 and 7 are views showing the configuration of the safety opening cap according to the second embodiment of the present invention.

In the case of the safety opening cap shown in FIGS. 6 and 7, a cut line is formed across the center of the cap body 101, and the cap body is bent or bent when the can lid is opened by using the safety opening cap. The purpose is to facilitate the adhesion between the cap body 101 and the can lid 20 in the opening process.

That is, the cap body 101 is formed with a cap body refraction cutting line 210 so that the central portion of the cap body 101 is bent when the can lid 20 is opened. The cap body refraction cut line 210 is formed so as to cross the periphery of the center of the cap body and is connected to the refraction cut hole 170 and the refraction cut line 160, or the refraction cut hole 170 and the above. It can be formed without being connected to the refraction cut line 160. The cap body refraction cut line 210 may be formed one or more depending on the size of the can 10, and the cap body refraction cut line 210 may be formed with a notch or thin.

17 and 18 are views showing the configuration of the upper surface of the safety opening cap according to the third embodiment of the present invention.

With reference to FIGS. 17 and 18, a case where the tab passing means is formed with a cut line different from the structure of the cut portion exemplified in the above embodiment and a raised portion support wall 243 is exemplified.

That is, as shown, when the user pressurizes the cap body 101 downward, a gap is formed so that the tab 30 can be inserted in front of the tab raising portion 130, and the safety opening cap 100 is opened. A cutout portion 240 is configured to allow the tab raising portion 130 to come into contact with the lower side surface of the tab when the tab is pushed toward the tab 30 side and the tab is inserted.

In the cutting portion 240, the first cutting line 241 cut so that a part of the tab raising portion 130 is lowered when the cap body 101 is pressed is set at a position where the first cutting line 241 is separated from the tab raising portion 130 for a predetermined time. It is formed by connecting with the formed second cutting line 242.

When the cap body 101 is pushed downward and moved toward the tab 30 side, a part of the tab raising portion 130 is lowered to a position lower than the second cutting line 242, and the second cutting line 242 and the above While the tab 30 is inserted between the tab raising portion 130 and the tab raising portion 130, the tab raising portion 130 causes a rotational operation in which one side end of the tab 30 spreads from the can lid 20.

As described above, in the case of the third embodiment, as shown in FIG. 17, the tab 30 formed by forming the tab raising portion 130 and spreading apart from the can lid 20 by the tab raising portion 130 does not need to be used with a fingernail. Can be opened after raising. Further, as shown in FIG. 18, behind the tab raising portion 130, the raised portion support wall 243 projecting at the same height as the rear (high side of the inclined surface) of the tab raising portion 130 having the inclined surface 131 is raised by the tab. It can be formed so as to be adjacent to or in contact with the portion 130.

The raised portion support wall 243 is for preventing the tab raised portion 130 from being raised excessively upward when the tab 30 is pulled while being raised at the time of opening.

That is, when the cap body 101 or the tab raising portion 130 is pressed downward while being pushed toward the tab 30 side, the first cutting line 241 is formed up to the tab raising portion 130 as shown in FIG. 18, and the tab raising portion 130 is formed. Only a part of 130 is lowered to a lower position, and the raised portion support wall 243 remains as it is.

Then, when the tab 30 is pulled while being raised, the lowered tab raising portion 130 is raised, but the raising portion support wall 243 supports the tab raising portion 130 and the tab raising portion 130 is excessively upward. It can be prevented from being awakened.

19 and 20 are views showing the configuration of the upper surface of the safety opening cap according to the fourth embodiment of the present invention.

In the safety opening cap 100 of the fourth embodiment, the tab raised portion 130 is formed on the upper surface of the cap body 101 in the same manner, but instead of the cut portion or the cut line in front of the tab raised portion 130, This is a case where the tab passing means is formed by a tab inflow hole 340 having a size capable of inserting the tab 30.

In FIGS. 19 and 20, the tab inflow hole 340 has a fan shape or a diamond shape, but any pattern such as a rectangular shape or an elliptical shape can be used as long as the tab 30 can be inserted or flowed into the tab 30. There will be.

Also in the case of the fourth embodiment, if the user pressurizes the cap body 101 downward, the tab raising portion 130 will be lowered, and if the user pushes the safety opening cap 100 toward the tab side, Rotation is performed while the tab 30 is inserted through the tab inflow hole 340 and the lower surface of the tab 30 is raised by the tab raising portion 130.

Then, if the raised tab 30 is raised vertically with a finger instead of a nail, the tab 30 is adjacent to or in contact with the tab support surface 341.

Therefore, if the tab 30 raised at the time of opening is pulled, the tab 30 is supported by the tab support surface 341 and is not pushed down, and the position of the tab 30 is fixed. Then, the can lid 20 and the cap body 101 are accompanied and opened, and the can lid 20 and the cap body 101 are equally bent or bent during the opening process to improve the adhesion, so that the can can be opened safely. Can be done.

In the case of the fourth embodiment, as shown in FIG. 20, the outer wall 110 in contact with the tab inflow hole 340 can also be removed.

FIG. 25 is a diagram showing a configuration of a safety opening cap according to a further embodiment of the present invention.

In the case of the upper surface of the safety opening cap shown in FIG. 25, the first cut line 141 and the second cut line 142, and the first sub cut line 143 and the second of the cut portion 140 which is a tab passing means without forming the tab raising portion 130. It may consist of a sub-cut line 144 and a cut break hole 150.

As described above, the width at which the first sub-cutting line 143 and the second sub-cutting line 144 are opened together with the cutting portion 140 is expanded. This makes it easy to pressurize the safety opening cap 100 and insert the tab 30 into the cutout 140.

To use the safety opening cap 100 configured in this way, if the safety opening cap 100 is pushed downward and moved toward the tab 30 while the tab 30 is inserted into the gap of the cutout portion 140, the safety opening cap 100 is used. The tab 30 can be opened by pulling the tab 30 after raising the safety opening cap 100 by putting a hand on the rear lower surface of the safety opening cap 100 without raising the tab 30 with a fingernail or a finger.

It goes without saying that the first sub-cutting line 143 and the second sub-cutting line 144 can consist of curved lines without forming corners, if necessary.
