Description

용기의 나사산 구조Threaded structure of the container
본 발명은 약품, 음료, 식품, 화장품 등에 사용되는 용기의 나사산 구조에 관한 것으로, 더욱 상세하게는 짧은 손목 회전으로 뚜껑을 여닫을 수 있으면서도, 뚜껑의 닫힘 상태를 안정적으로 유지할 수 있는 용기의 나사산 구조에 관한 것이다.The present invention relates to a screw thread structure of a container used for drugs, beverages, food, cosmetics, etc., and more particularly, to the screw thread structure of a container that can open and close the lid with a short wrist rotation, while stably maintaining the closed state of the lid it's about
일반적으로 통상의 약품, 음료, 식품, 화장품 등에 사용되는 용기의 구성을 보면, 내용물이 수납되는 용기몸체의 상부 외주면으로 뚜껑이 결합될 수 있도록 나선형을 이루는 1줄 나사산이 형성되어 있고, 상기 용기몸체의 나사산에 결합되도록 뚜껑의 테두리 내면으로 나선형을 이루는 1줄 나사산이 형성되어 있다.In general, if you look at the configuration of containers used for drugs, beverages, food, cosmetics, etc., a single threaded thread forming a spiral is formed so that the lid can be coupled to the upper outer circumferential surface of the container body in which the contents are accommodated, and the container body A one-line thread forming a spiral is formed on the inner surface of the rim of the lid so as to be coupled to the thread of the lid.
상기와 같은 나선형 나사산을 가지는 용기몸체는 나사산의 시작점과 끝점이 하나로 형성되어 있어, 소비자가 뚜껑을 체결할 때 길게 회전시켜야만 체결 완료될 뿐만 아니라, 제조 시 뚜껑 체결에 따른 작업시간이 오래 걸리기 때문에 생산라인이 지연되어 생산성을 저하시킨다는 문제점이 있었다.The container body having a spiral thread as described above has a single start point and an end point of the screw thread, so it is not only completed when the consumer rotates the lid for a long time when fastening the lid, but also takes a long time to work due to the lid tightening during manufacture. There was a problem that the line was delayed and productivity was lowered.
상기한 1줄 나사산을 가지는 용기의 단점을 해결하기 위하여 종래에는 1줄 나사산의 경사각으로 형성된 3줄 나사산으로서, 대한민국 등록실용신안 제20-0246286호(2001.08.31.등록)의 크림타입 화장품 용기의 나사산 구조가 제안되어 왔으며, 또한 시중에서 흔히 볼 수 있는 상기 3줄 나사산과 비슷한 개념의 철제 뚜껑과 결합되는 유리용기의 나사산이 널리 사용되고 있다.In order to solve the disadvantages of the container having the above-mentioned single thread, in the prior art, as a three-line thread formed with an inclination angle of the one-line thread, the cream type cosmetic container of Republic of Korea Registered Utility Model No. 20-0246286 (Registered on Aug. 31, 2001) A screw thread structure has been proposed, and a screw thread of a glass container coupled with a steel lid having a similar concept to the three-line screw thread commonly seen in the market is widely used.
그러나, 상기한 3줄 나사산 구조는 1줄 나사산에 준하는 낮은 경사각의 한계로 인해 더 많은 나사산을 분포시키지 못할 뿐만 아니라, 뚜껑측 나사산이 용기몸체측 나사산의 상면 및 우측면과 정확히 합치되지 못한 단점이 있으며, 상기한 철제 뚜껑과 결합되는 유리용기의 나사산 구조는 상기한 3줄 나사산보다 경사각을 크게 함으로써 나사산들의 간격을 좁히거나 겹치게 만들어 다수의 나사산을 분포시켜 더욱 짧은 손목 회전으로 뚜껑을 여닫을 수 있게 만든 반면에, 큰 경사각으로 인한 불안정성을 극복하기 위해, 뚜껑이 주로 강한 탄성을 지닌 철로 만들어지며, 용기몸체는 철의 국소적 압력을 견디기 위해 주로 유리로 만들어지고 있다.However, the above-described three-line thread structure not only does not distribute more threads due to the limitation of a low inclination angle equivalent to that of a one-line thread, but also has the disadvantage that the lid side thread does not exactly match the upper and right sides of the container body side thread. , The screw thread structure of the glass container combined with the above-mentioned iron lid makes it possible to close or overlap the gaps between the threads by making the inclination angle larger than the three-row screw thread, thereby distributing a number of threads so that the lid can be opened and closed with a shorter wrist rotation. In order to overcome the instability caused by the large inclination angle, the lid is mainly made of iron with strong elasticity, and the container body is mainly made of glass to withstand the local pressure of iron.

It is intended to provide a screw thread structure of a container that can be manufactured regardless of material and material, and can be opened and closed quickly and stably with only a short wrist rotation during use.

이와 같이 구성된 본 발명의 나사산 구조는 짧은 손목 회전만으로 용기몸체(10)로부터 뚜껑(20)을 쉽고 안정되게 여닫을 수 있다.The screw thread structure of the present invention configured as described above can easily and stably open and close the lid 20 from the container body 10 only by a short wrist rotation.
즉, 용기몸체(10)의 뚜껑결합부(12)의 외주면에 형성된 다수의 제1 나사산(14)과 이에 대응되는 다수의 제2 나사산(24)이 뚜껑(20)의 용기결합부(22)의 내주면에 형성되어 뚜껑(20)을 일방향으로 회전시키면, 뚜껑(20)측 제2 나사산(24)의 하면(24b) 혹은 좌측면(24c)이 도 6(a)과 같이 용기몸체(10)측 제1 나사산(14)의 상면(14a) 및 연장부(14d) 혹은 우측면(14c)과 슬라이딩 되면서 제1 나사산(14)측 하면(14b)의 우측 단부에서 좌측 단부 방향으로 이동됨과 동시에 하강하게 되고, 이로 인해 뚜껑(20)의 천정은 용기몸체(10)의 뚜껑결합부(12)의 상단에 맞닿을 때까지 회전하게 된다.That is, the plurality of first screw threads 14 formed on the outer circumferential surface of the lid coupling portion 12 of the container body 10 and the plurality of second screw threads 24 corresponding thereto are the container coupling portions 22 of the lid 20 . When the lid 20 is rotated in one direction and formed on the inner circumferential surface of the lid 20, the lower surface 24b or the left surface 24c of the second screw thread 24 on the lid 20 side is the container body 10 as shown in FIG. 6(a). While sliding with the upper surface 14a and the extended portion 14d or the right side 14c of the first screw thread 14, it moves from the right end of the lower surface 14b on the first screw thread 14 side to the left end direction and descends at the same time and, thereby, the ceiling of the lid 20 rotates until it comes into contact with the upper end of the lid coupling portion 12 of the container body 10 .
이때, 용기몸체(10)로부터 뚜껑(20)이 닫히도록 회전된 후 정지되면, 뚜껑(20)측 제2 나사산(24)은 일례로 든 도 6(a)에 표시한 화살표 방향과 같이 대체로 용기몸체(10)측 제1 나사산(14)의 하면(14b)에 대해 대체로 우측 단부와 좌측 단부 사이에 위치되면서 서로 대응되는 마찰력에 의해 결합된 상태를 유지하게 된다.At this time, if the lid 20 is stopped after being rotated from the container body 10 to close, the second screw thread 24 on the lid 20 side is generally the container as in the direction of the arrow shown in FIG. 6 (a) as an example. The body 10 side is positioned between the right end and the left end with respect to the lower surface 14b of the first screw thread 14 to maintain a coupled state by frictional force corresponding to each other.
이러한 닫힘 상태에서 용기몸체(10)로부터 뚜껑(20)을 타방향으로 회전시키면, 뚜껑(20)측 제2 나사산(24)의 상면(24a)이 용기몸체(10)측 제1 나사산(14)의 하면(14b)의 경사각을 타고 우측 방향으로 이동됨으로써 열리게 된다. When the lid 20 is rotated in the other direction from the container body 10 in this closed state, the upper surface 24a of the second thread 24 on the lid 20 side is the first thread 14 on the container body 10 side. It is opened by moving in the right direction riding the inclination angle of the lower surface 14b.
이때, 뚜껑(20)측 제2 나사산(24)의 하면(24b) 혹은 좌측면(24c)은 도 6(b)과 같이 용기몸체(10)측 제1 나사산(14)의 연장선(14d)과 상면(14a) 혹은 우측면(14c)과 슬라이딩 되면서 상승함으로써 분리된다. At this time, the lower surface 24b or the left side 24c of the second screw thread 24 on the lid 20 side is an extension line 14d of the first screw thread 14 on the side of the container body 10 as shown in FIG. 6(b) and It is separated by rising while sliding with the upper surface (14a) or the right surface (14c).
즉, 일례로서 용기몸체(10)측 다수의 제1 나사산(14)이 뚜껑결합부(12)의 외주면에 대해 원주방향을 따라 예를 들어 120°의 간격을 두고 형성되고, 뚜껑(20)측 다수의 제2 나사산(24)이 용기결합부(22)의 내주면에 대해 원주방향을 따라 예를 들어 120°의 간격을 두고 형성될 경우, 다수의 제1 나사산(14)과 제2 나사산(24)은 45°의 범위 내에서 서로 대응되게 맞물려 결합되거나 해제되는 구조이기 때문에 짧은 손목 회전만으로 용기몸체(10)로부터 뚜껑(20)을 쉽게 여닫을 수 있다.That is, as an example, a plurality of first screw threads 14 on the side of the container body 10 are formed at intervals of, for example, 120° along the circumferential direction with respect to the outer circumferential surface of the lid coupling portion 12, the lid 20 side When the plurality of second threads 24 are formed at intervals of, for example, 120° along the circumferential direction with respect to the inner circumferential surface of the container coupling part 22, the plurality of first threads 14 and the second threads 24 ) can be easily opened and closed from the container body 10 from the container body 10 because of the structure that is engaged or released to correspond to each other within the range of 45 ° only a short wrist rotation.
