Description

캔 뚜껑 및 이를 채용한 캔 용기Can lids and can containers with them
본 발명은 캔 뚜껑 및 이를 채용한 캔 용기에 관한 것으로서, 더욱 상세하게는 회전탭을 회전시키는 동작에 의해 캔의 개봉부를 용이하게 개봉할 수 있도록 구성된 캔 뚜껑 및 이를 채용한 캔 용기에 관한 것이다. The present invention relates to a can lid and a can container employing the same, and more particularly, to a can lid and a can container employing the can lid configured to be easily opened by the operation of rotating the rotary tab.
도 1은 종래에 널리 사용되는 캔 용기에 있어서 뚜껑 일부의 구성을 보여주는 도면이다. 도시된 바와 같이, 캔 용기는 원통형의 몸체(1)와, 몸체 상단부에 밀봉되도록 결합되는 뚜껑(2)으로 구성된다. 1 is a view showing the configuration of a part of the lid in a conventional can container widely used. As shown, the can container consists of a cylindrical body 1 and a lid 2 which is coupled to seal the upper end of the body.
상기 뚜껑(2)에는 캔의 개봉부를 용이하게 개봉하기 위한 수단이 마련되는데, 구체적으로 개봉부를 따라 대략 원형으로 절단선이 미리 새겨진 스코어(score)(3)가 형성되고, 상기 스코어(3)가 형성된 부분을 가압하기 위한 압착탭(4)이 구비된다. 상기 압착탭(4)은 예를 들어 그 중심부가 리벳팅됨으로써 뚜껑(2)에 고정되어 있다.The lid 2 is provided with means for easily opening the can of the can. Specifically, a score 3 is formed in which the cutting line is pre-engraved in a substantially circular shape along the opening, and the score 3 is A pressing tab 4 for pressing the formed portion is provided. The pressing tab 4 is fixed to the lid 2, for example by riveting its center portion.
상기와 같은 구성을 가진 종래의 캔 뚜껑에 있어서, 압착탭(4)의 끝단을 들어올리게 되면 지렛대 원리에 의해 압착탭(4)의 타단부가 개봉부를 가압하면서 스코어(3)의 파단이 시작되게 되고, 이어서 압착탭(4)의 끝단을 더욱 들어올림에 따라 스코어(3)를 따라 파단이 전파되면서 캔이 개봉된다.In the conventional can lid having the above-described configuration, when the end of the pressing tab 4 is lifted, the break of the score 3 starts while the other end of the pressing tab 4 presses the opening part by the lever principle. Then, the can is opened while breaking propagates along the score 3 as the end of the pressing tab 4 is further lifted.
이와 같이, 종래의 캔 뚜껑에서는, 한 손으로 음료캔을 파지하고 다른 한 손으로 압착탭(4)을 들어올리는 동작을 취해야만 한다. Thus, in the conventional can lid, the operation of holding the beverage can with one hand and lifting the press tab 4 with the other hand must be taken.
또한, 상기 압착탭(4)이 뚜껑(2) 상면에 거의 밀착된 상태로 부착되어 있기 때문에 손톱이나 기타 도구를 사용하여 압착탭(4)의 끝단을 밀어 올려야 하는 불편도 뒤따른다. In addition, since the pressing tab 4 is attached to the upper surface of the lid 2 almost in close contact, the inconvenience of having to push up the end of the pressing tab 4 using a nail or other tool is also accompanied.
나아가, 유출구를 개봉하기 위해서 압착탭(4)을 과도하게 들어올리거나 타단을 손가락으로 눌러주는 과정에서 종종 부상이 초래되기도 한다. 그리고, 압착탭(4)에 의해 유출구가 개봉되면 다시 압착탭(4)을 원래 위치로 되돌려 놓기 위해 반대쪽으로 젖히는 등 캔 개봉을 위해 여러 단계의 과정이 요구되는 불편이 있다. Furthermore, injuries are often caused in the process of excessively lifting the press tab 4 or pressing the other end with a finger to open the outlet. Then, when the outlet is opened by the pressing tab 4, there are inconveniences in that several steps are required for opening the can, such as flipping the pressing tab 4 back to its original position.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 압착탭으로 가압하고 들어올리는 종래의 소위 푸시-앤-업(push-and-up) 방식이 아니라, 탭을 단순하게 회전시키는 동작에 의해 캔을 용이하게 개봉할 수 있는 캔 뚜껑을 제공하는 것을 목적으로 한다.The present invention is to solve the above problems, not the conventional so-called push-and-up method of pressing and lifting with the pressing tab, the can by the operation of simply rotating the tab.

도 2에는 본 발명의 바람직한 실시예에 따른 캔 용기의 뚜껑 일부에 대한 구성이 사시도로 도시되어 있다. Figure 2 is a perspective view of the configuration of a portion of the lid of the can container according to a preferred embodiment of the present invention.
도면을 참조하면, 본 발명의 캔 용기는 음료 등의 내용물을 담을 수 있도록 원통형으로 형성된 몸체(10)와, 상기 몸체(10)의 상단에 결합되어 개봉 수단에 의해 유출구가 개봉됨으로써 내용물이 배출되도록 하는 캔 뚜껑(20)을 포함한다.Referring to the drawings, the can container of the present invention is coupled to the upper end of the body 10 and the body formed in a cylindrical shape so as to contain the contents of the beverage, such that the outlet is opened by the opening means to discharge the contents It includes a can lid 20.
알려진 바와 같이 상기 캔 용기의 몸체(10)는 금속 또는 플라스틱으로 제조된다. 또한 상기 뚜껑(20)도 알루미늄이나, 스틸 또는 그 합금 등의 금속 소재로 제조되며, 몸체(10)의 상단부와 뚜껑(20)의 외주부를 기계적으로 절곡함으로써 상호 밀봉결합될 수 있다. 이러한 제조 및 결합 방식은 이미 당업계에서 알려진 사항이므로 더 이상의 상세한 설명은 생략한다.As is known, the body 10 of the can container is made of metal or plastic. In addition, the lid 20 is also made of a metal material such as aluminum, steel, or alloys thereof, and may be mutually sealed by mechanically bending the upper end of the body 10 and the outer peripheral portion of the lid 20. This preparation and coupling method is already known in the art, and thus further detailed description is omitted.
본 발명에 따른 캔 뚜껑(20)은 베이스 플레이트(21)와, 상기 베이스 플레이트(21)에 회전가능하게 결합되어 있는 회전탭(30)을 포함한다. 상기 회전탭(30)이 생략된 상태의 캔 뚜껑에 대한 도면이 도 3 및 도 4에 도시되어 있다.The can lid 20 according to the present invention includes a base plate 21 and a rotating tab 30 rotatably coupled to the base plate 21. 3 and 4 show can lids with the rotary tab 30 omitted.
도시된 바와 같이, 상기 베이스 플레이트(21)의 상면에는 유출구를 개봉하기 위한 스코어(S)가 새겨짐으로써 개봉부(23)가 형성된다. 이미 알려진 바와 같이, 상기 스코어(S)는 개봉부(23)가 개봉되기 용이하도록 미리 새겨 놓은 절단선으로서, 원주의 일부를 제외하고 대략 원형이 되도록 형성된다. As shown, the opening 23 is formed on the top surface of the base plate 21 by marking the score S for opening the outlet. As is already known, the score S is a cut line which is carved in advance so that the opening 23 is easily opened, and is formed to be approximately circular except for a part of the circumference.
본 발명에 따르면 상기 스코어(S)는 파단돌기(27)에서 시작하여 반시계방향으로 연장되어 형성되는데 이것은 회전탭(30)의 회전에 의해 가장 용이하게 개봉부(23)를 개봉하기 위함이다.According to the present invention, the score S is formed to extend in the counterclockwise direction starting from the breaking protrusion 27, which is to open the opening 23 most easily by the rotation of the rotary tab 30.
상기 스코어(S)의 곡률은 특별하게 한정되지 않으며 후술하는 바와 같이 본 발명의 구성에 따라 회전탭(30)을 회전시킬 때 파단이 용이하게 일어날 수 있도록 다양하게 설정될 수 있다.The curvature of the score (S) is not particularly limited and may be variously set so that fracture may occur easily when rotating the rotary tab 30 according to the configuration of the present invention as described below.
바람직하게, 상기 스코어(S)는 두 줄로 나란하게 형성될 수도 있는데, 이때 외측에 위치한 스코어는 상대적으로 깊게 형성하여 실제 절개되도록 하는 반면, 내측에 위치한 스코어는 상대적으로 얕게 형성하여 절개가 용이하도록 촉진하는 역할을 한다. 본 실시예에서는 구분이 용이하도록 스코어를 한 줄로 나타내었다.Preferably, the score (S) may be formed side by side in two rows, wherein the score located on the outer side is formed to be relatively deep to make the actual incision, while the score located on the inner side is formed relatively shallow to facilitate the incision It plays a role. In this example, scores are shown in one line for easy identification.
상기 스코어(S)가 형성되지 않은 베이스 플레이트(21)의 중심부에는 회전축 돌기(24)가 형성되어 있으며, 상기 회전축 돌기(24)에는 회전탭(30)이 회전가능하도록 결합된다. A rotating shaft protrusion 24 is formed at the center of the base plate 21 on which the score S is not formed, and the rotating tab 30 is rotatably coupled to the rotating shaft protrusion 24.
구체적으로, 도 4의 A-A'선 및 B-B'선에 따른 단면을 각각 도시한 도 5와 도 6을 함께 참조하면, 상기 회전축 돌기(24)는 뚜껑(20)의 베이스 플레이트(21)에 일체로 돌출되도록 형성되며, 회전탭(30)에 형성된 회전통공(도 13의 31 참조)으로 삽입된 후 단부가 리벳팅됨으로써 걸림턱(도 5의 24a)에 의해 회전탭(30)과 결합될 수 있다.Specifically, referring to FIG. 5 and FIG. 6, which show cross-sections along the lines A-A 'and B-B' of FIG. 4, respectively, the rotation shaft protrusion 24 is the base plate 21 of the lid 20. It is formed so as to protrude integrally, and inserted into the rotary through-hole (see 31 of FIG. 13) formed in the rotary tab 30, the end is riveted by the locking tab (24a of FIG. Can be combined.
여기서, 상기 회전축 돌기(24)와 회전탭(30) 사이의 결합은 다양한 구조로 이루어질 수 있는데 도 7 내지 도 12에는 그러한 실시예들을 도시한 것이다. 따라서 도시된 예들을 포함하여 이들을 변형한 다양한 구성들 중에서 어느 하나를 채용할 수 있다.Here, the coupling between the rotary shaft projection 24 and the rotary tab 30 can be made in a variety of structures that are shown in Figures 7 to 12 such embodiments. Thus, any one of various configurations, including the illustrated examples, may be employed.
상기 회전탭(30)이 위치하는 부분의 베이스 플레이트(21)에는 손가락을 삽입하여 회전하기 용이하도록 오목바닥부(25)가 형성되어 있으며, 상기 뚜껑(20)의 강성을 보강하기 위해서 개봉부(23)를 비롯하여 필요한 영역에 보강리브(26)가 형성될 수 있다. The base plate 21 of the portion where the rotary tab 30 is located is formed with a concave bottom portion 25 so as to easily rotate by inserting a finger, the opening 23 to reinforce the rigidity of the lid 20 In addition, the reinforcing rib 26 may be formed in the required area.
본 발명에 따르면, 상기 오목바닥부(25)의 경계는 파단돌기(27)를 둘러싸고 있는 스코어(S)에 인접하여 감싸는 듯이 형성되는 것이 바람직하다. 이 경우, 회전탭(30)을 회전시킬 때 파단돌기(27) 주변에 응력이 집중되는 것을 촉진함으로써 스코어의 파단이 더욱 용이해진다.According to the present invention, it is preferable that the boundary of the concave bottom portion 25 is formed so as to surround the score S surrounding the fracture protrusion 27. In this case, the breakage of the score is further facilitated by promoting the concentration of stress around the breaking projection 27 when the rotary tab 30 is rotated.
도 13에는 상기 회전탭(30)의 구성이 도시되어 있으며, 도 14 내지 도 17은 도 13에서 각각 a-a'선, b-b'선, c-c'선 및 d-d'선에 따른 단면을 나타낸다. 여기서, 도 16 및 도 17은 설명의 편의를 위해 파단돌기(27)가 결합된 상태로 도시하였다.FIG. 13 shows the configuration of the rotary tab 30, and FIGS. 14 to 17 show lines a-a ', b-b', c-c 'and d-d' respectively in FIG. Along the cross section. 16 and 17 illustrate the breaking protrusions 27 coupled to each other for convenience of description.
상기 도면들을 참조하면, 회전탭(30)에는 상기 회전축 돌기(24)가 삽입되는 회전통공(31)이 형성되어 있으며, 상기 회전통공(31)의 결합부를 중심으로, 손가락으로 걸어서 회전시키는 구동단부(30a)와, 그 반대쪽의 종동단부(30b)로 나뉘어진다. Referring to the drawings, the rotary tab 30 is formed with a rotating through hole 31 into which the rotating shaft protrusion 24 is inserted, and a driving end rotating by walking with a finger around the engaging portion of the rotating through hole 31. 30a and the driven end part 30b on the opposite side.
바람직하게 상기 구동단부(30a)의 길이가 종동단부(30b)보다 길어서 회전시 지렛대 효과를 얻을 수 있도록 구성될 수 있지만 반드시 이것에 한정되는 것은 아니다.Preferably the length of the drive end (30a) is longer than the driven end (30b) can be configured to obtain a lever effect when rotating, but is not necessarily limited thereto.
상기 회전탭(30)은 바람직하게 강성을 가지도록 스틸, 알루미늄 및 이들의 합금을 포함하는 금속 소재로 제조된다. 상기 회전탭(30)의 구동단부(30a)와 종동단부(30b)에는 손가락이 걸리기에 용이하도록 상부로 돌출된 굴곡부(32a)(32b)가 각각 형성될 수 있다. The rotating tab 30 is preferably made of a metal material including steel, aluminum and alloys thereof to have rigidity. Drive portions 30a and driven ends 30b of the rotary tab 30 may be formed with bent portions 32a and 32b protruding upwards to facilitate finger catching.
이러한 구성에 따라서, 사용자는 예를 들어, 검지와 엄지를 상기 구동단부(30a)의 굴곡부(32a)와 종동단부(30b)의 굴곡부(32b)에 걸고 도 2의 화살표와 같이 회전탭(30)을 회전시킬 수 있다. 이 경우, 회전탭(30)은 양단에서 회전력을 동시에 인가받게 되므로 보다 용이하게 회전될 수 있다.According to this configuration, the user can, for example, fasten the index finger and thumb to the bent portion 32a of the drive end portion 30a and the bent portion 32b of the driven end portion 30b, as shown by the arrow of FIG. 2. Can be rotated. In this case, the rotary tab 30 can be rotated more easily because the rotary tab is simultaneously applied to both ends.
본 발명에 따르면, 상기 회전탭(30)과 베이스 플레이트(21)의 스코어(S)가 형성된 인접부를 상호 연결시켜 회전탭(30)이 회전할 때 상기 스코어(S)의 파단이 시작되도록 하는 파단 개시 수단을 포함한다. According to the present invention, the breaks of starting the breaking of the score (S) start when the rotary tab 30 is rotated by interconnecting the adjacent portions where the score (S) of the rotary tab 30 and the base plate 21 are formed. Initiation means.
본 발명에 따르면, 상기 파단 개시 수단은 상기 회전탭(30)에 형성된 파단개시절곡부(33)와, 상기 베이스 플레이트(21) 상면에 형성되어 상기 파단개시절곡부(33)에 결합되는 파단돌기(27)를 포함한다.According to the present invention, the break initiation means is a break start bending portion 33 formed on the rotary tab 30, the break projection formed on the upper surface of the base plate 21 coupled to the break start bending portion 33 And (27).
구체적으로, 상기 회전탭(30)에 있어서 회전통공(도 13의 31)의 일측에는 파단개시절곡부(33)가 형성되어 있으며, 상기 파단개시절곡부(33)에 형성되어 있는 결합통공(35)을 통해 파단돌기(27)와 결합된다(도 6 및 도 17 참조).Specifically, the break opening bent portion 33 is formed at one side of the rotating through hole (31 in FIG. 13) in the rotary tab 30, and the coupling through hole 35 formed in the break starting bent portion 33 is formed. It is coupled with the breaking protrusion 27 through) (see FIGS. 6 and 17).
상기 파단개시절곡부(33)의 주위에는 파열슬롯(36)이 형성되는데, 이 파열슬롯(36)은 캔을 개봉하기 위해 회전탭(30)을 회전시킬 때 파단돌기(27)가 쉽게 꺾일 수 있도록 소재의 일부를 제거한 부분이다. A tear slot 36 is formed around the break start bending part 33, and the tear slot 36 can be easily broken when the rotary tab 30 is rotated to open a can. So that part of the material is removed.
이를 위해 상기 파열슬롯(36)은 회전탭(30)이 회전하는 방향쪽으로 치우쳐 형성된다. 바람직하게, 회전탭이 금속으로 제작될 경우, 상기 파열슬롯(36) 형성을 위해 절개되는 부분을 그 아래로 굴곡시킴으로써 파열슬롯(36) 주변부의 강성을 보강할 수 있다.To this end, the tear slot 36 is formed to be biased toward the direction in which the rotating tab 30 rotates. Preferably, when the rotating tab is made of metal, it is possible to reinforce the rigidity of the periphery of the tear slot 36 by bending the cut portion below to form the tear slot 36.
상기 파단개시절곡부(33)는 파열슬롯(36)에 의해 구분된 영역으로서 바람직하게는, 상기 파단개시절곡부(33)의 테두리를 도 16에서 보는 바와 같이 절곡시켜 강성을 보강할 수 있다. The break initiation bent portion 33 is a region divided by the tear slot 36, and preferably, the edge of the break initiation bent portion 33 may be bent as shown in FIG. 16 to reinforce rigidity.
도 6을 참조하면, 상기 파단개시절곡부(33)는 회전탭(30)으로부터 하방으로 경사지게 연장된 제1 경사부(41)와, 상기 제1 경사부(41)의 끝에서 수평으로 연장된 수평부(42)와, 상기 수평부(42)의 끝에서 상방으로 경사지게 연장된 제2 경사부(43)로 구성된다.Referring to FIG. 6, the break start bending portion 33 extends horizontally from the end of the first inclined portion 41 and the first inclined portion 41 inclined downwardly from the rotary tab 30. It consists of a horizontal part 42 and the 2nd inclination part 43 extended inclined upwards from the end of the said horizontal part 42. As shown in FIG.
상기 제1 경사부(41)는 후술하는 바와 같이 회전탭(30)을 회전시킬 때 파단개시절곡부(33)가 하방으로 원활하게 절곡될 수 있도록 하며, 이를 위해 제1 경사부(41)와 회전탭(30)의 경계 부분에는 복수의 절개부(도 13의 44 참조)가 더 형성될 수 있다.The first inclined portion 41 is to be bent smoothly bent downward break 33 when rotating the rotary tab 30 as described later, for this purpose and the first inclined portion 41 A plurality of cutouts (see 44 in FIG. 13) may be further formed at the boundary portion of the rotary tab 30.
상기 수평부(42)에는 파단돌기(27)가 결합되는 결합통공(35)이 형성되는데, 바람직하게 상기 결합통공(35)의 경계부에 있는 소재를 절곡함으로써 강성을 보강하도록 한다. The horizontal portion 42 is formed with a coupling hole 35 to which the break projection 27 is coupled, preferably to reinforce the rigidity by bending the material at the boundary of the coupling hole 35.
상기 제2 경사부(43)는 회전탭(30)을 회전시킬 때 베이스 플레이트(21)의 개봉부(23)를 가압하는 부분으로서, 5 ~ 15°정도의 적정한 각도로 상방으로 경사지게 형성된다. The second inclined portion 43 is a portion for pressing the opening 23 of the base plate 21 when the rotating tab 30 is rotated, and is inclined upwardly at an appropriate angle of about 5 to 15 degrees.
상기와 같이 제2 경사부(43)를 마련하는 이유는 회전탭(30)을 회전시킬 때 파단돌기(27)가 어느 정도 먼저 절곡된 다음에, 제2 경사부(43)가 개봉부(23)를 가압하도록 하기 위함이다. 그렇지 않고, 상기 제2 경사부(43)를 수평으로 형성할 경우에는 파단돌기(27)를 절곡하는데 필요한 힘과 제2 경사부(43)에 의해 개봉부(23)를 가압하는 힘이 초기에 집중되어 회전탭(30)을 회전시키기 위해 보다 큰 힘이 요구될 수 있으며, 이것은 사용자의 불편을 초래한다.The reason for providing the second inclined portion 43 as described above is that when the breaking protrusion 27 is first bent to some extent when the rotary tab 30 is rotated, the second inclined portion 43 is the opening portion 23. This is to pressurize. Otherwise, when the second inclined portion 43 is formed horizontally, the force necessary to bend the breaking protrusion 27 and the force for pressing the opening 23 by the second inclined portion 43 are initially concentrated. Thus, a larger force may be required to rotate the rotary tab 30, which causes inconvenience to the user.
상기 파단돌기(27)는 상기 스코어(S)의 파단이 시작되는 부분(Po)에 인접하도록 형성되며, 회전탭(30)이 회전하는 힘에 의해 회전방향으로 꺾이면서 상기 스코어(S)의 파단이 개시되도록 한다. The breaking protrusion 27 is formed to be adjacent to the portion Po at which the breaking of the score S starts, and the breaking tab 27 is broken in the rotational direction by the force of the rotating tab 30. To be initiated.
상기 파단돌기(27)는 회전탭(30)의 결합통공(35)으로 삽입되어 단부가 리벳팅됨으로써 회전탭(30)에 고정될 수 있다.The breaking protrusion 27 may be inserted into the coupling through hole 35 of the rotary tab 30 to be fixed to the rotary tab 30 by riveting an end portion thereof.
여기서, 상기 파단돌기(27)와 회전탭(30)의 결합 구조는 다양하게 변형될 수 있는데, 앞서 회전축 돌기의 결합 방식을 예시한 도 7 내지 도 12는 파단돌기와 회전탭 사이의 결합 구조에도 동일하게 적용될 수 있는 것으로 이해되어야 한다.Here, the coupling structure of the breaking protrusion 27 and the rotary tab 30 may be variously modified. FIGS. 7 to 12 exemplarily show a coupling method of the rotating shaft protrusion, the same as the coupling structure between the breaking protrusion and the rotating tab. It should be understood that the present invention can be applied.
본 발명에 따르면 상기 스코어(S)는 회전탭(30)의 회전력에 의해 파단이 용이하게 개시되며, 또한 파단이 개시된 후 전파가 원활하게 이루어질 수 있도록 형상이 설계된다.According to the present invention, the score (S) is easily broken by the rotational force of the rotary tab 30, and the shape is designed so that propagation can be made smoothly after the break is initiated.
도 4를 참조하면, 상기 스코어(S)는 파단을 촉진하기 위해 시작점(Po)이 파단돌기(27) 외측에 근접하도록 형성되며, 상기 시작점(Po)에서부터 파단돌기(27)의 적어도 일부를 감싸도록 양측으로 연장되는 메인 스코어(Sm)와 보조 스코어(Sa)를 포함한다. Referring to FIG. 4, the score S is formed such that the starting point Po is close to the outside of the breaking protrusion 27 to facilitate the breaking, and surrounds at least a portion of the breaking protrusion 27 from the starting point Po. And a main score (Sm) and an auxiliary score (Sa) extending to both sides.
상기 메인 스코어(Sm)는 개봉부(23)를 기준으로 상기 시작점(Po)에서부터 반시계방향으로 형성되는데, 이러한 메인 스코어(Sm)가 파단됨으로써 개봉부(23)가 개봉되게 된다. 본 발명자의 연구에 따르면, 상기 회전탭(30)이 회전축 돌기(24)를 중심으로 시계방향으로 회전할 때, 상기 메인 스코어(Sm)는 개봉부(23)를 중심으로 반시계방향으로 연장된 상태라야 원활한 절취가 가능한 것으로 나타났다.The main score Sm is formed in the counterclockwise direction from the starting point Po based on the opening part 23, and the opening part 23 is opened by breaking the main score Sm. According to the inventor's research, when the rotary tab 30 rotates clockwise about the rotary shaft protrusion 24, the main score Sm extends counterclockwise around the opening 23. It was found that smooth cutting is possible.
상기 보조 스코어(Sa)는 상기 메인 스코어(Sm)의 반대쪽 방향{즉, 개봉부(23)를 기준으로 시계방향}으로 소정 길이만큼 연장되어 파단돌기(27)의 파단을 보조하는 기능을 한다.The auxiliary score Sa extends by a predetermined length in a direction opposite to the main score Sm (that is, in a clockwise direction with respect to the opening part 23) to serve to break the breaking protrusion 27.
본 발명의 바람직한 실시예에 따르면, 상기 스코어(S)의 파인 정도(깊이)는 서로 다르게 설정될 수 있다. 즉, 보조 스코어(Sa)의 적어도 일부는 메인 스코어(Sm)에 비해 스코어가 더 얕은 깊이를 가지도록 형성될 수 있다. According to a preferred embodiment of the present invention, the fineness (depth) of the score (S) may be set differently. That is, at least a part of the auxiliary score Sa may be formed such that the score has a shallower depth than the main score Sm.
따라서 회전탭(30)을 회전시킬 경우 깊이가 깊은 스코어가 얕은 스코어보다 먼저 파단될 수 있다. 스코어의 파인 정도(깊이)는 파단이 원하는 순서대로 일어나도록 적절히 설정될 수 있다.Therefore, when the rotary tab 30 is rotated, a deeper score may break before a shallower score. The degree of fineness (depth) of the scores may be appropriately set such that the breaks occur in the desired order.
본 발명에 따르면, 스코어(S)의 파단이 쉽게 일어나도록 보조하는 절곡선이 베이스 플레이트(21)에 형성될 수 있다. 구체적으로, 메인 스코어(Sm)의 안쪽에는 메인 스코어(Sm)의 파단을 촉진하는 절곡선(도 4의 28a)이 형성되어 있으며, 파단돌기(27)를 둘러싸는 스코어(S)와 오목바닥부(25)의 경계 사이에 있는 베이스 플레이트(21) 상에도 스코어의 파단 개시를 촉진하는 절곡선(도 4의 28b)이 형성되어 있다.According to the present invention, a bend line may be formed in the base plate 21 to assist the breakage of the score S easily. Specifically, a bend line (28a in FIG. 4) is formed inside the main score Sm to promote breakage of the main score Sm, and the score S and the concave bottom portion surrounding the breaking protrusion 27 are formed. A bend line (28b in FIG. 4) is also formed on the base plate 21 between the boundaries of 25 to promote the breaking start of the score.
이러한 절곡선(28a)(28b)은 스코어와 유사하지만 파단되지 않도록 깊이가 얕게 패인 절단선이다.These bend lines 28a and 28b are cut lines similar to the score but shallowly cut in depth so as not to break.
본 발명에 따르면, 도 4에서 알 수 있는 바와 같이, 회전탭(30)에 형성된 파단개시절곡부(33)의 제2 경사부(43)가 개봉부(23)의 상면에 놓이게 된다. 이것은 회전탭(30)을 회전시킬 때 제2 경사부(43)에 의해 개봉부(23)를 가압하기 위함인데, 더욱 바람직하게 상기 제2 경사부(43)는 개봉부(23)에 형성된 보강리브(26)를 가압하도록 구성될 수 있다.According to the present invention, as can be seen in Figure 4, the second inclined portion 43 of the break start bending portion 33 formed in the rotary tab 30 is placed on the upper surface of the opening (23). This is to press the opening 23 by the second inclined portion 43 when rotating the rotary tab 30, more preferably the second inclined portion 43 is a reinforcing rib formed in the opening (23) ( 26) may be configured to pressurize.
그러면, 상기와 같은 구성을 가진 본 발명의 바람직한 실시예에 따른 캔 용기에 있어서 유출구를 개봉하는 동작에 대해서 살펴보기로 한다. Then, the operation of opening the outlet in the can container according to a preferred embodiment of the present invention having the configuration as described above will be described.
본 발명에 따른 캔 용기는 사용자가 한 손으로 캔 용기를 파지한 상태에서 손가락을 사용하여 회전탭(30)을 회전시킴으로써 간단하게 개봉할 수 있다. 즉, 사용자는 손가락의 엄지와 검지를 상기 회전탭(30)의 구동단부(30a)와 종동단부(30b)의 굴곡부(32a)(32b)에 각각 걸어 도 2의 화살표 방향으로 회전시키게 된다. The can container according to the present invention can be easily opened by rotating the rotary tab 30 using a finger in a state in which the user holds the can container with one hand. That is, the user rotates the thumb and index finger of the finger in the direction of the arrow of FIG. 2 by walking on the driving end portion 30a of the rotary tab 30 and the bent portions 32a and 32b of the driven end portion 30b, respectively.
그러면, 회전탭(30)은 상기 회전축 돌기(24)를 중심으로 시계방향으로 회전하게 된다.Then, the rotary tab 30 is rotated in a clockwise direction about the rotary shaft projection (24).
이렇게 회전탭(30)을 회전시키면 파단개시절곡부(33)에 결합되어 있는 파단돌기(27)가 도 18에 도시된 점선 화살표와 같이 절곡되면서 스코어(S)의 파단이 개시된다.When the rotary tab 30 is rotated as described above, the breaking protrusion 27 coupled to the breaking start bending part 33 is bent as shown by the dotted arrow shown in FIG.
즉, 상기 회전탭(30)의 회전이 시작된 직후에, 회전탭(30)에 형성된 파열슬롯(36)으로 인해 파단개시절곡부(33)는 아래쪽으로 굴곡되고 이에 따라 파단돌기(27)가 회전 방향 쪽으로 꺾이게 된다. That is, immediately after the rotation of the rotary tab 30 is started, the fracture start bending portion 33 is bent downward due to the tear slot 36 formed in the rotary tab 30, and the fracture protrusion 27 rotates accordingly. It will be bent in the direction.
이때, 제1 경사부(41)와 절개부(44)는 파단개시절곡부(33)가 하방으로 쉽게 절곡되도록 하며, 파단돌기(27)의 절곡을 촉진한다. 일단 파단돌기(27)가 절곡되면 회전탭(30)의 구동력이 파단돌기(27)에 그대로 전달되게 된다.At this time, the first inclined portion 41 and the cutout portion 44 allow the break-opening bent portion 33 to be easily bent downward, and promote bending of the breakout protrusion 27. Once the breaking protrusion 27 is bent, the driving force of the rotary tab 30 is transmitted to the breaking protrusion 27 as it is.
위와 같은 과정에 의해, 파단돌기(27)가 꺾이면서 파단돌기(27)를 둘러싸고 있던 스코어(S)의 시작점(Po)에서 파단이 시작된다. 즉, 도 19의 (a), (b)에 도시된 바와 회전탭(30)의 제1 경사부(41)와 파단돌기(27)가 절곡되면서 상기 스코어(S)의 시작점(Po)에서 파단이 개시된다.By the above process, breakage starts at the starting point Po of the score S surrounding the breaking protrusion 27 while the breaking protrusion 27 is bent. That is, as shown in (a) and (b) of FIG. 19, the first inclined portion 41 and the breaking protrusion 27 of the rotating tab 30 are bent and broken at the starting point Po of the score S. FIG. This is disclosed.
이러한 스코어의 파단은 메인 스코어(Sm)와 보조 스코어(Sa)를 따라서 양측으로 전파된다.The breaking of this score propagates to both sides along the main score Sm and the auxiliary score Sa.
동시에, 파단개시절곡부(33)의 제2 경사부(43) 끝단이 상기 개봉부(23)의 상면을 하방으로 가압하게 된다. 따라서, 개봉부(23)는 서서히 아래로 가압되어 절곡되기 시작한다.At the same time, the end of the second inclined portion 43 of the break start bending portion 33 presses the upper surface of the opening 23 downward. Therefore, the opening part 23 gradually presses down and starts to bend.
그런 다음 회전탭(30)을 더욱 회전시키면 메인 스코어(Sm)의 지점(도 18의 P1)까지 스코어가 파단된다.Then, when the rotary tap 30 is further rotated, the score is broken up to the point (P 1 of FIG. 18) of the main score Sm.
이 상태에서 회전탭(30)을 계속 회전시키면 파단개시절곡부(33)의 제2 경사부(43)가 개봉부(23)를 하방으로 더욱 가압하게 되고, 이 과정에서, 메인 스코어(Sm)의 파단은 원호부를 따라서 지점(P2)까지 전체적으로 전파되게 된다.When the rotary tab 30 is continuously rotated in this state, the second inclined portion 43 of the break start bending portion 33 presses the opening portion 23 further downward, and in this process, the main score Sm The break is to propagate entirely up to the point P 2 along the arc.
그 결과, 개봉부(23)는 도 19의 (c)에 도시된 바와 같이, 캔 용기 내부로 밀리면서 완전히 굴곡된다. 따라서 유출구가 충분히 개봉되므로 사용자는 캔 내부에 담긴 내용물을 음용 또는 섭취할 수 있게 된다. As a result, the opening 23 is completely curved while being pushed into the can container, as shown in Fig. 19C. Therefore, since the outlet is sufficiently open, the user can drink or ingest the contents contained in the can.
비록 본 명세서에서는 구체적인 실시예를 도시된 도면을 참조로 설명하였으나, 이 건 출원당시의 기술수준에서 상기 실시예에 포함된 구성들을 다양하게 변형하여 발명을 구성할 수 있는 것으로 이해되어야 한다. Although specific embodiments have been described with reference to the drawings, it should be understood that the present invention can be configured by variously modifying the configurations included in the embodiments at the time of filing the application.
본 발명의 캔 뚜껑 및 캔 용기에 따르면, 회전탭을 회전시키는 간단한 동작에 의해 유출구를 개봉할 수 있으므로 종래의 푸시-앤-업 방식에 비해 사용이 매우 편리하다. According to the can lid and can container of the present invention, since the outlet can be opened by a simple operation of rotating the rotary tab, it is very convenient to use compared to the conventional push-and-up method.
나아가, 과도한 힘을 사용하여 억지로 탭을 가압하지 않아도 되므로 캔 개봉 과정에서 종종 발생하던 부상이나 안전사고를 예방할 수 있다.In addition, since it is not necessary to pressurize the tab by using excessive force, it is possible to prevent injuries or safety accidents often occurred during the can opening process.
