Description

개방상태 유지기능을 갖는 용기마개A container cap having an open state maintenance function

본 발명은 개방상태 유지기능을 갖는 용기마개에 관한 것으로서, 구체적으로 용기의 주둥이에 고정된 상태를 유지하는 표시링과 연결된 상태로 있으며, 용기의 개구를 개폐하는 마개본체가 용기의 개구를 개방한 상태에서 용기의 개구로부터 최대한 벌어진 상태에 있도록 하는 개방상태 유지기능을 갖는 용기마개에 관한 것이다.[0001] The present invention relates to a container stopper having an open state maintaining function, and more particularly to a container stopper which is in a state of being connected to an indicator ring which is kept fixed to the spout of a container, To a state in which the opening of the container is maximally opened from the opening of the container.

일반적으로 생수를 비롯한 식음료나 오일, 도료, 화학약품 등의 액상물질을 수용하는 용기는 액상물질의 출입이 있도록 한 주둥이를 형성하고 있다.Generally, bottles containing drinking water, food and beverages, liquids such as oil, paints, and chemicals are formed into a snout so that liquid substances can flow in and out.

또한, 상술한 주둥이에는 액상물질의 출입을 제한하기 위해 용기 주둥이의 개구를 개폐하는 용기마개가 설치된다.Further, the above-mentioned spout is provided with a container cap for opening and closing the opening of the container spout to restrict the entry and exit of the liquid material.

용기(B)의 주둥이(N)와 용기마개(10)의 일반적인 결합 구조는, 도 1 내지 도 3에 도시한 바와 같이, 용기(B) 중 상대적으로 돌출한 형상을 갖는 주둥이(N)의 외주면(E/S)에 수나사(M/S)를 형성하고, 이에 대응하여 덮는 용기마개(10)의 내주면(I/S)에 암나사(F/S)를 형성하여 이들 상호 간의 나사 결합 또는 그 결합 해제의 관계로 이루어진다.The general connection structure of the spout N of the container B and the container stopper 10 is such that the outer peripheral surface of the spout N having a relatively protruding shape in the container B, (F / S) is formed on the inner circumferential surface (I / S) of the container stopper 10 covering the male screw (M / S) Release relationship.

최근에 개발이 이루어진 용기마개(10)는, 대한민국 등록특허공보 제10-1325850호(포장용기 마개: 이하, '선행기술1'이라 함)와 대한민국 등록특허공보 제10-1038894호(포장용기 마개: 이하, '선행기술2'라 함)에서 확인되는 바와 같이, 용기(B)로부터 분리한 경우에 분실할 위험과 분리한 상태에서 주변으로부터의 오염 가능성을 해소하기 위하여 용기(B)의 주둥이(N)를 개방한 이후에도 용기(B)의 주둥이(N)에 용기마개(10)가 연결된 상태에 있도록 하고 있다.The container stopper 10 that has been developed recently is disclosed in Korean Patent Publication No. 10-1325850 (hereinafter referred to as "Prior Art 1") and Korean Patent Publication No. 10-1038894 (Hereinafter referred to as " Prior Art 2 "), in order to eliminate the risk of being lost when separated from the container B and the possibility of contamination from the surroundings in a separated state, The container stopper 10 is connected to the spout N of the container B even after the container stopper 10 is opened.

위의 선행기술1, 2에 따른 용기마개(10)는, 도 1과 도 2에서 참조되는 바와 같이, 천장부(12)와 천장부(12)에 연이은 하측으로 원통 형상을 이루며 내벽에 암나사(F/S)를 형성한 측벽부(14)를 포함한 마개본체(16)를 이루고, 마개본체(16)의 하부에 방사상 배치의 복수 브릿지(20)와 일측의 힌지부(22)를 통해 일체로 연결한 표시링(18)을 구비한 구성으로 이루어진다.1 and 2, the container stopper 10 according to the prior arts 1 and 2 has a cylindrical shape extending downward from the ceiling portion 12 and the ceiling portion 12 and has a female thread F / S are integrally connected to a lower portion of the stopper body 16 through a plurality of radially arranged bridges 20 and a hinge portion 22 on one side And a display ring (18).

또한, 힌지부(22) 하부의 표시링(18) 부위 중 상하 폭 방향 중간 부위에는 가로 방향 구간에 절개한 형상의 슬릿(24)을 형성하고, 슬릿(24) 아래의 내벽 둘레에는 걸림부(30)를 돌출 형성하고 있다.A slit 24 is formed at an intermediate portion of the display ring 18 below the hinge portion 22 in the transverse direction in an upper and lower width direction intermediate portion thereof and a slit 24 is formed around the inner wall below the slit 24 30 are protruded and formed.

이로부터 마개본체(16)를 회전시켜 용기(B)의 주둥이(N)를 개봉할 때에는, 마개본체(16)는 상승하지만, 용기(B)에 마련한 걸림턱(C)과 지지턱(S/C) 사이에 위치한 표시링(18)은 걸림부(30)가 걸림턱(C)에 걸려 상승하지 못하므로, 표시링(18)과 마개본체(16) 사이의 절개부(25)를 연결한 브릿지(20)의 파단이 이루어진다.The stopper body 16 is raised while the stopper main body 16 is rotated to unseal the spout N of the container B but the stopper C and the stopper S / The indication ring 18 located between the indication ring 18 and the stopper body 16 is connected to the stopper ring 18 because the stopper ring 30 is not caught by the stopper C The bridge 20 is broken.

이에 따라 상술한 브릿지(20)의 파단 여부는, 용기(B)에 대한 용기마개(10)의 개봉이 있었는지 여부를 확인할 수 있도록 한다.Thus, whether or not the above-described bridge 20 is broken can confirm whether or not the container stopper 10 has been opened with respect to the container B.

여기서, 상술한 힌지부(22)는 표시링(18) 중 슬릿(24) 위치의 상부와 연결되어 있고, 슬릿(24)은 용기(B)의 주둥이(N)로부터 마개본체(16)가 승강할 때에 벌어짐으로써 힌지부(22)를 통한 표시링(18)과 마개본체(16)의 연결 상태를 유지시킨다.The hinge portion 22 is connected to the upper portion of the display ring 18 at the position of the slit 24 and the slit 24 is formed in a state in which the stopper body 16 is lifted from the spout N of the container B So that the connection state between the indication ring 18 and the cap body 16 through the hinge portion 22 is maintained.

또한, 선행기술1, 2는 힌지부(22) 양측에 마개본체(16) 및 표시링(18) 부위에 이르는 절개한 형상의 트임부(26)를 형성하고 있으며, 이러한 트임부(26)는 힌지부(22)가 내·외측으로 꺾일 수 있도록 공간을 확보기 위한 것이며, 마개본체(16)와 표시링(18)의 경계 위치에서 상측인 마개본체(16) 방향으로 길이를 갖는다.In the prior arts 1 and 2, a cut-away portion 26 is formed on both sides of the hinge portion 22 to reach the end portions of the stopper body 16 and the indication ring 18. The cut- And has a length in the direction of the upper stopper body 16 at the boundary position between the stopper body 16 and the indicator ring 18. The stopper body 18 has a length in the direction of the stopper body 16,

그리고, 트임부(26) 사이에 위치한 힌지부(22)는, 마개본체(16)와 표시링(18) 사이의 상하 방향 중간 부위를 따라 내측에서 외측 방향으로 두께가 얇은 형상을 이루며, 그 위치에서 마개본체(16)와 표시링(18)의 수평인 접선 방향을 기준으로 굽어지도록 한 단차부(28)를 형성하고 있으며, 이에 따라 단차부(28)의 수평 방향 양측은 마개본체(16)와 표시링(18)의 표면보다 외측으로 더 돌출한 형상을 이룬다.The hinge portion 22 located between the tweezers 26 is formed in a shape having a thin thickness from the inside to the outside along the middle portion in the vertical direction between the cap body 16 and the indication ring 18, The stepped portion 28 is formed so as to be curved with respect to the horizontal tangent direction of the stopper body 16 and the indicator ring 18 so that both sides of the stepped portion 28 in the horizontal direction are in contact with the stopper body 16, And the display ring 18, as shown in Fig.

위의 설명과 같이, 단차부(28)의 가로방향 양측 부위가 마개본체(16)와 표시링(18)의 표면보다 외측으로 더 돌출한 상태는, 사용자가 손으로 잡을 때에 이질감을 야기하여 불편할 뿐 아니라, 용기마개(10)가 강한 힘으로 체결되었거나 용기(B)와 용기마개(10) 사이의 내용물이 굳은 상태에서 무리한 힘으로 개방을 시도할 때에 사용자의 손을 손상시킬 위험이 있다.As described above, a state in which both side portions of the step portion 28 in the transverse direction are projected further outward than the surfaces of the stopper body 16 and the indicator ring 18 causes a sense of heterogeneity when the user holds it by hand, There is a risk of damaging the user's hand when the container stopper 10 is fastened with a strong force or when the contents between the container B and the container stopper 10 are hardened and the user attempts to open the container with excessive force.

무엇보다고, 선행기술1, 2의 힌지부(22)는 비록 단차부(28)를 두어 용기(B)로부터 마개본체(16)가 젖혀질 수 있도록 하고 있으나, 마개본체(16)의 젖혀진 각도는 결국 힌지부(22)의 탄성적 복원력의 영향을 받아 자연상태에서 용기(B)의 개구를 일부 가리는 위치에 있게 되므로, 사용자가 용기(B)의 주둥이(N)에 입을 대고 음용하고자 할 때에 걸리적거리는 위치에 있어 인위적으로 젖힌 상태에 있도록 해야 하는 불편을 초래하였다.The hinge portion 22 of the prior arts 1 and 2 allows the stopper body 16 to be tilted from the container B with the stepped portion 28, The angle is eventually influenced by the resilient restoring force of the hinge portion 22 to be in a position to partially cover the opening of the container B in the natural state so that the user is likely to wear the spout N of the container B It was inconvenient to be in an artificial position.

이러한 불편을 해소하기 위한 방안으로, 대한민국 등록특허공보 제10-0981240호(이하, '선행기술3'이라 함)와 도 3에 표현된 바와 같이, 힌지부(22') 사이에 버팀대(32)를 구비하여 용기 주둥이의 외벽에 대하여 버팀대(32)의 단부가 지지를 받도록 함으로써 마개본체(16)의 개방 상태가 견고하도록 한 기술이 개시된 바 있다.In order to solve this inconvenience, a brace 32 is provided between the hinge portion 22 'and a hinge portion 22', as shown in FIG. 3, with Korean Patent Registration No. 10-0981240 (hereinafter referred to as "Prior Art 3" So that the end portion of the brace 32 is supported by the outer wall of the container spout so that the opening state of the cap body 16 is made firm.

여기서, 상술한 버팀대(32) 단부 위치는 슬릿(24) 위치의 상측에 위치하고 있다.Here, the above-mentioned end position of the brace 32 is located above the slit 24 position.

그러나, 위의 선행기술3에 의하면, 도 3과 도 4에서 확인되는 바와 같이, 마개본체(16)가 용기(B)의 개구를 개방한 상태에 있어, 슬릿(24) 상측의 표시링(18) 부위는 걸림턱(C)에 의해 고정되는 표시링(18) 부위로부터 슬릿(24)의 양 끝단 위치(P1)와, 표시링(18)에 형성한 트임부(26) 부위(P2)와 마개본체(16)와 버팀대가 연결되는 부위(P3)를 기준으로 비틀리고, 그 길이는 상술한 도 3의 "P1~P3" 구간을 연결한 길이(d1~d3)를 이룬다.3 and 4, when the stopper body 16 is in the state in which the opening of the container B is open, the display ring 18 on the upper side of the slit 24 Of the slit 24 from the portion of the display ring 18 fixed by the engagement jaw C and the position P2 of the twisting portion 26 formed on the display ring 18 The length is d1 to d3 in which the section of the plug body 16 is connected to the portion P3 to which the brace is connected and the length thereof is the length of "P1 to P3" of FIG.

즉, 상술한 비틀림 구간의 길이(d1~d3)는, 버팀대(32)의 돌출 길이(d3)를 포함하여 이루어지고, 결국 이렇게 비틀린 구간(d1~d3)은, 용기(B) 주둥이(N)이 외벽에 대하여 비틀린 상태에서 여유공간(D) 이상의 공간을 형성하여 버팀대(32)가 지지를 받기 곤란한 상태로 있어, 결국 마개본체(16)는 비틀림에 대한 복원력에 의해 용기(B) 주둥이(N)의 개구를 가리는 위치에 놓인다.That is, the lengths d1 to d3 of the twisted section include the protruding length d3 of the brace 32, and thus the twisted sections d1 to d3 are formed in the spout N of the container B, A space over the clearance D is formed in a twisted state with respect to the outer wall so that the strut 32 is difficult to receive the support so that the stopper main body 16 is deformed by the restoring force against the twist of the container B Of the openings.

이를 보완하기 위해서는 마개본체(16)의 상측으로 이어진 트임부(28)의 상측 부위 위치는 마개본체(16) 내벽의 암나사(F/S)와 간섭하지 않는 최대 상측 위치까지 형성할 것과, 그 위치에서 버팀대(32)의 길이를 충분히 길게 형성해야 한다.In order to compensate this, the upper side portion position of the twisting portion 28, which is connected to the upper side of the stopper body 16, is to be formed up to a maximum upper side position which does not interfere with the female screw F / S on the inner wall of the stopper body 16, The length of the brace 32 should be sufficiently long.

하지만, 버팀대(32)의 길이 연장은 결국 버팀대(32)가 용기(b) 주둥이(N)의 내벽에 밀착되게 힘을 제공하지 못하고, 걸쳐지는 정도여서, 용기(B)의 개구로부터 마개본체(16)가 벌어지는 각도는 90° 미만에 그치고, 이는 사용자로 하여금 손으로 용기(B)의 개구로부터 마개본체(16)를 간섭 없는 벗어난 위치에 있도록 조치를 취하게 하는 번거로움을 야기한다.However, the extension of the braces 32 does not provide any force to bring the braces 32 into close contact with the inner wall of the spout N of the container b, 16 is less than 90 degrees, which inconveniences the user from taking an action so as to position the cap body 16 away from the opening of the container B by hand.

또한, 이러한 문제를 해결하기 위하여 선행기술3에는 버팀대(32) 부위에 용기(B) 주둥이(N)에 형성한 걸림턱(C) 또는 수나사(M/S)에 대응하여 걸쳐지도록 한 돌출부(T)를 형성하고 있으나, 이러한 돌출부(T)는 용기(B) 주둥이(N)의 개구를 폐쇄한 상태에서 마개본체(16)의 외측 표면으로부터 돌출한 상태로 있음에 따라 사용자가 용기(B)의 개구를 개방하고자 할 때에 걸리적거리는 불편함을 야기한다.In order to solve such a problem, in the prior art 3, a projecting portion T (see FIG. 1), which is provided so as to cover the engagement claw C or the male screw M / S formed on the spout N of the container B, The protrusion T protrudes from the outer surface of the cap body 16 in a state where the opening of the spout N of the container B is closed so that the user can press the container B The opening of the opening causes an inconvenience.

그리고, 마개본체(16)를 개방한 상태에서, 슬릿(24) 상측의 표시링(18)과 힌지부(22) 및 마개본체(16) 사이의 연결 부위(P1~P3)는 강제적으로 비틀린 상태를 이룸에 따라 이들 연결 부위(P1~P3) 중 두께를 얇게 형성한 부위는 비틀린 상태에서 복원하려는 힘과 버팀대의 지지력 사이의 물리적인 힘을 받아 쉽게 끊어지는 문제와 그에 따른 마개본체(16)의 분실 위험을 갖는다.The connecting portions P1 to P3 between the display ring 18 on the upper side of the slit 24 and the hinge portion 22 and the stopper body 16 are forcedly twisted in a state in which the stopper body 16 is opened The portions of the connecting portions P1 to P3 which are formed thin are easily broken due to the physical force between the force to be restored and the supporting force of the strut in a twisted state, There is a risk of loss.

본 발명은, 상술한 종래 기술의 문제점들을 해결하기 위한 것으로서, 본 발명의 목적은, 용기마개의 계속적인 사용에도 마개본체와 표시링 사이의 연결 상태를 손상 내지 파손을 방지하여 안정적으로 유지하게 하고, 음용 등 용기를 사용함에 있어, 마개본체가 용기 주둥이의 개구로부터 완전이 벗어난 위치에 있도록 하는 개방상태 유지기능을 갖는 용기마개를 제공함에 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art described above and it is an object of the present invention to provide an apparatus and a method for preventing deterioration of a connection state between a stopper body and a display ring, In the use of a container such as a drinking utensil, there is provided a container cap having an open state holding function such that the cap body is located at a position deviating completely from the opening of the container spout.

상기 목적을 달성하기 위한 본 발명의 일 실시 예에 따른 개방상태 유지기능을 갖는 용기마개의 특징적인 구성은, 용기의 주둥이로부터 이탈이 방지되는 표시링과; 용기 주둥이의 외주면에 대해 나사체결 하는 마개본체와; 상기 마개본체와 표시링 사이의 절개부 둘레 중 일부 구간의 상기 마개본체와 표시링를 상호 잇는 힌지부; 및 상기 마개본체와 표시링을 상기 절개부 둘레를 따라 간격을 두고 연결하며, 마개본체의 개방시에 절단되게 한 브릿지;를 구비하여 이루어진 개방상태 유지기능을 갖는 용기마개에 있어서, 상기 힌지부는 양측 절개부와 근접하는 폭 방향 양측 가장자리 부위가 외측에서 내측으로 깊이를 이루고, 상기 마개본체와 표시링 및 힌지부에 일체로 연결한 꺾임유도홈을 형성하고, 폭 방향 중심의 하측 부위는 하측 방향으로 연장 돌출한 형상의 돌기부를 형성한 것으로 이루어지고, 상기 표시링은 상하 높이 방향의 중간 부위 중 설정한 구간에 슬릿을 형성한 것으로 이루어지고, 상기 돌기부에 대응하는 부위에 돌기부와 간격을 두고 근접하며 하측으로 깊이를 갖는 오목부를 형성한 것으로 이루어진다.According to an aspect of the present invention, there is provided a container stopper having an open state maintaining function, the container stopper including: an indication ring which is prevented from being detached from the spout of the container; A cap body for screwing the outer peripheral surface of the container spout; A hinge portion which interconnects the stopper main body and a display ring of a section of the circumference of the cutout portion between the stopper main body and the display ring; And a bridge which connects the cap body and the indicator ring at intervals along the circumference of the incision and which is made to be cut when the cap body is opened. In the container cap having the open state holding function, Wherein a width direction side edge portion close to the incision portion has a depth from outside to inside and a bending guide groove integrally connected to the stopper main body and the display ring and the hinge portion is formed, Wherein the display ring is formed by forming a slit in a predetermined section of an intermediate portion in the vertical direction and is formed so as to be close to the protruding portion at a portion corresponding to the protruding portion And a concave portion having a depth downward is formed.

또한, 상기 꺾임유도홈은 외측에서 내측으로 깊이를 이루며, 상기 힌지부의 폭 방향 중심에서 가장자리 방향으로 점차 두께가 감소하는 형상의 경사면을 이루어, 상기 꺾임유도홈 중 상대적으로 얇은 상기 양측 절개부 위치에서 높이 방향의 상기 마개본체에 접하는 부위가 절개 가능하도록 함이 바람직하다.The bending guide groove has a depth from the outside to the inside and has an inclined surface whose thickness gradually decreases from the center in the width direction of the hinge portion to the edge direction. In the bending guide groove, It is preferable that a portion in contact with the stopper body in the height direction is cutable.

그리고, 상기 힌지부 양측의 상기 슬릿 상부인 상기 양측 표시링에는 폭과 길이 및 외측에서 내측 방향으로 깊이를 갖는 비틀림홈을 형성한 것으로 이루어지고, 상기 각 비틀림홈의 길이 방향 중 상측 방향 일단은 상기 힌지부에 근접하고, 하측 방향 타단은 상기 슬릿의 선단 방향에 근접하도록 이미 설정한 기울기를 갖도록 한 것을 상기 표시링을 따라 하나 이상 형성토록 함이 바람직하다.The two side indicating rings on both sides of the slit on both sides of the hinge portion are formed with torsion grooves having a width and a length and a depth in the inside direction from the outside, one end of the torsion grooves in the upper direction of the longitudinal direction It is preferable to form one or more slits along the display ring so as to have a predetermined inclination so as to be close to the hinge portion and the other end in the downward direction to be close to the tip direction of the slit.

상기한 본 발명에 따르면, 꺾임유도홈이 접하는 마개본체와 힌지부 및 슬릿 상부의 표시링 부위와 일체로 연결되고, 돌기부가 슬릿의 수평 위치보다 아래에 위치함으로써, 마개본체의 개방시에 슬릿의 양끝단에서 힌지부로 이어져 비틀린 표시링의 비틀림 복원력과 이를 포함한 장력에 대응하여 돌기부가 용기의 주둥이에 강한 힘으로 지지를 받음에 따라 용기 주둥이에 대한 마개본체의 젖혀진 각도가 종래 기술에 비교하여 더욱 확대되어 용기 주둥이의 개구를 통한 내용물의 유출시에 간섭 위치로부터 안정적으로 벗어나 있어 사용이 편리한 효과가 있다.According to the present invention described above, the bending guide groove is integrally connected to the bunging main body, the hinge portion, and the display ring portion of the upper portion of the slit, and the projecting portion is positioned below the horizontal position of the slit, The tilting angle of the stopper main body with respect to the container spout is higher than that of the prior art as the protrusion is supported by the strong force on the spout of the container in correspondence with the torsional restoring force of the tilted indication ring which is led from both ends to the hinge, So that it can be stably removed from the interference position when the contents are leaked out through the opening of the mouth of the container.

또한, 상술한 꺾임유도홈의 경사면에 의해 상대적으로 얇은 부위 일부가 뜯어짐이 가능하고, 뜯어진 부위가 외측으로 돌출하지 않도록 내측으로 깊이를 이루고 있어, 사용자의 손이 닿지 않도록 할 뿐 아니라 외측으로 돌출하지 않아 미관을 해치지 않는 이점이 있다.In addition, the inclined surfaces of the bending guide grooves allow a portion of a relatively thin portion to be torn, and the torn portion has a depth inward so as not to protrude outward, There is an advantage that it does not protrude and does not harm aesthetics.
