Dental impression materials are typically used to house impression material cartridge assemblies. The impression material cartridge assembly is used by attaching a mixing tip for mixing and discharging the two to the impression material cartridge each containing a silicone base and a curing agent.
등록특허 10-0954836에는 종래 인상재 카트리지와 믹싱팁의 결합구조가 개시되어 있다. 종래 인상재 카트리지와 믹싱팁의 결합을 위해서는 믹싱팁과 인상재 카트리지의 위치를 맞추어 정렬한 후 삽입하고, 결합날개를 회전결합홈에 각각 회전시켜 위치를 구속시킨다. 즉, 종래 인상재 카트리지와 믹싱팁의 결합을 위해서는 가압하여 위치를 정렬한 후, 회전시키는 두 가지 단계를 거쳐야 했다. 이에 치아 인상을 위해 작업자가 인상재 카트리지를 결합시킬 때 상대적으로 준비시간이 지연되는 단점이 있었다. Patent 10-0954836 discloses a coupling structure of a conventional impression material cartridge and a mixing tip. In order to combine the conventional impression material cartridge and the mixing tip, the mixing tip and the impression material cartridge are aligned and inserted after insertion, and the coupling blades are constrained by rotating the coupling blades in the rotary coupling grooves, respectively. In other words, in order to combine the conventional impression material cartridge and the mixing tip, after pressing and aligning the position, it had to go through two stages of rotation. This has a disadvantage in that the preparation time is relatively delayed when the operator combines the impression material cartridge for the impression of the teeth.
또한, 개시된 믹싱팁은 믹싱튜브와 캡부가 일체로 형성되어 인상재 카트리지의 연결용 소켓에 결합된다. 이에, 믹싱팁과 인상재 카트리지가 결합된 상태에서 실리콘 베이스와 경화제가 경화되어 굳어버리면 믹싱팁이 인상재 카트리지로부터 분리하기가 어려운 문제가 있다. 즉, 개시된 믹싱팁은 결합과 분리를 위해 인상재 카트리지에 회전을 하기 때문에 마찰면적이 상대적으로 커서 실리콘 베이스와 경화제가 경화되어 굳어버리면 회전이 되지 않아 분리가 어려워진다. In addition, the disclosed mixing tip is formed integrally with the mixing tube and the cap is coupled to the connection socket of the impression material cartridge. Thus, when the silicone base and the hardener are cured and hardened in a state in which the mixing tip and the impression material cartridge are combined, the mixing tip is difficult to be separated from the impression material cartridge. In other words, since the mixing tip is rotated in the impression material cartridge for bonding and separation, the friction area is relatively large, and when the silicone base and the hardener are hardened and hardened, the mixing tip is not rotated, and thus the separation is difficult.

결합후크(124)는 믹싱팁(120)이 인상재 카트리지(110)에 원터치 방식으로 간편하게 착탈되도록 한다. 결합후크(124)는 팁본체(121)의 양측에 돌출 형성된다. 결합후크(124)는 도 1과 도 4에 도시된 바와 같이 팁본체(121)에 연결된 연결축(124a)과, 연결축(124a)에 대해 상부에 위치한 누름판(124b)과, 연결축(124a)에 대해 하부에 위치한 후크본체(124d)를 포함한다. The coupling hook 124 allows the mixing tip 120 to be detachably attached to the impression material cartridge 110 in a one-touch manner. Coupling hook 124 is formed to protrude on both sides of the tip body (121). As shown in FIGS. 1 and 4, the coupling hook 124 includes a connecting shaft 124a connected to the tip body 121, a pressing plate 124b positioned at an upper side with respect to the connecting shaft 124a, and a connecting shaft 124a. It includes a hook body (124d) located at the bottom with respect to.
연결축(124a)은 팁본체(121)와 후크본체(124d)를 연결한다. 연결축(124a)은 작업자가 누름판(124b)을 가압할 때 지렛대의 중심축 역할을 하여 적은 힘으로 후크본체(124d)가 탄성적으로 변형되도록 한다. 연결축(124a)은 힘을 전달할 수 있는 최소의 길이로 구비된다. The connecting shaft 124a connects the tip body 121 and the hook body 124d. The connecting shaft 124a serves as a central axis of the lever when the operator presses the pressing plate 124b so that the hook body 124d is elastically deformed with a small force. The connecting shaft 124a is provided with a minimum length capable of transmitting a force.
누름판(124b)과 후크본체(124d)는 연결축(124a)을 중심으로 일체로 연결되게 구비된다. 누름판(124b)은 연결축(124a)을 중심으로 상부방향으로 일정길이 연장형성되며 사용자에 의해 가압된다. 누름판(124b)의 판면에는 사용자의 가압이 용이하도록 요철돌기(124c)가 복수개 형성된다. 누름판(124b)의 상단부는 반경방향 외측으로 일정 각도 절곡형성되어 사용자의 접지가 용이하도록 한다. The pressing plate 124b and the hook body 124d are provided to be integrally connected with respect to the connecting shaft 124a. The pressing plate 124b is formed to extend a predetermined length in the upper direction about the connecting shaft 124a and is pressed by the user. On the plate surface of the pressing plate 124b, a plurality of uneven protrusions 124c are formed to facilitate pressurization of the user. The upper end of the pressing plate 124b is formed to be bent at an angle radially outward to facilitate the grounding of the user.
후크본체(124d)는 연결축(124a)을 중심으로 하부영역으로 연장형성된다. 후크본체(124d)의 길이는 믹싱팁(120)이 인상재 카트리지(110)에 결합되었을 때 상부플랜지(117)의 저면에 닿을 수 있게 구비된다. 한 쌍의 후크본체(124d)는 누름판(124b)의 가압에 의해 반경방향 외측으로 벌어진 후, 누름판(124b)의 가압이 해지되면 반경방향 내측으로 좁혀지며 상부플랜지(117)에 걸림결합된다. The hook body 124d is extended to the lower region about the connecting shaft 124a. The length of the hook body 124d is provided to be able to contact the bottom surface of the upper flange 117 when the mixing tip 120 is coupled to the impression material cartridge 110. The pair of hook bodies 124d is opened radially outward by the pressing plate 124b, and then narrows radially inward when the pressing plate 124b is released and is engaged with the upper flange 117.
이 때, 후크본체(124d)의 하단부에는 상부플랜지(117)의 저면에 걸림지지되는 걸림고리(124e)가 절곡형성된다. 걸림고리(124e)는 후크본체(124d)의 탄성변형에 의해 상부플랜지(117)의 배면에 접촉지지되어 믹싱팁(120)과 인상재 카트리지(110)의 결합상태가 유지되도록 한다. At this time, at the lower end of the hook body 124d is formed a hook 124e that is supported on the bottom of the upper flange 117 is bent. The catch ring 124e is supported by contact with the rear surface of the upper flange 117 by the elastic deformation of the hook body 124d so that the mixing state of the mixing tip 120 and the impression material cartridge 110 is maintained.
한편, 믹싱팁(120)의 외측에는 지지부(116)에 접촉되는 접촉돌기(125)가 서로 이격되게 한 쌍이 구비된다. 접촉돌기(125)는 팁본체(121)가 인상재 카트리지(110)에 결합될 때 한 쌍의 지지부(116)과 접촉되며 믹싱팁(120)의 위치가 고정되도록 한다. 즉, 접촉돌기(125)는 팁본체(121)의 외측으로 돌출형성되어 팁본체(121)가 한 쌍의 지지부(116) 사이에 억지끼워맞춤 되도록 한다. 이를 위해 접촉돌기(125)의 돌출높이는 한 쌍의 접촉돌기(125)를 포함한 믹싱팁(120)의 외경이 한 쌍의 지지부(116) 사이의 간격에 대응되도록 구비되는 것이 바람직하다. On the other hand, the outer side of the mixing tip 120 is provided with a pair so that the contact protrusion 125 in contact with the support 116 is spaced from each other. The contact protrusion 125 is in contact with the pair of supports 116 when the tip body 121 is coupled to the impression material cartridge 110, and the position of the mixing tip 120 is fixed. That is, the contact protrusion 125 is formed to protrude to the outside of the tip body 121 so that the tip body 121 is interfitted between the pair of supports 116. For this purpose, the height of the protrusion of the contact protrusion 125 is preferably provided such that the outer diameter of the mixing tip 120 including the pair of contact protrusions 125 corresponds to the interval between the pair of support portions 116.
믹싱팁(120)은 결합후크(124)에 의해 1차적으로 인상재 카트리지(110)와 고정되고, 지지부(116)과 접촉돌기(125)의 접촉에 의해 2차적으로 위치가 구속된다. The mixing tip 120 is first fixed to the impression material cartridge 110 by the coupling hook 124, and the position is secondarily constrained by the contact of the support part 116 and the contact protrusion 125.
특히, 한 쌍의 결합후크(124)와 한 쌍의 접촉돌기(125)가 서로 90도 간격으로 교호적으로 배치되므로 구속력이 전 영역으로 고르게 분포될 수 있다. 또한, 지지부(116)과 접촉돌기(125)의 접촉에 의해 끼워맞춤되므로 인상재의 배출 시에 믹싱팁(120)이 인상재 카트리지(110)에 대해 좌우 또는 상하로 유동되는 것을 방지할 수 있다. 따라서, 결합상태가 안정적으로 유지될 수 있고, 결합영역의 기밀이 유지되어 인상재의 외부 누출을 방지할 수 있다. In particular, since the pair of coupling hooks 124 and the pair of contact protrusions 125 are alternately disposed at 90 degree intervals, the restraining force may be evenly distributed over the entire area. In addition, since the support part 116 is fitted by the contact of the contact protrusion 125, the mixing tip 120 may be prevented from flowing left and right or up and down with respect to the impression material cartridge 110 when the impression material is discharged. Therefore, the bonded state can be stably maintained, and the airtightness of the bonded area can be maintained to prevent external leakage of the impression material.

As shown in FIG. 3, the socket 131 is provided such that an outer wall thereof contacts the inner wall of the tip body 121. Thereby, the external leakage of the impression material can be prevented.
격벽(132)은 제1연결관(133)과 제2연결관(134)으로 공급된 실리콘 베이스와 경화제가 서로 혼합되지 않은 상태로 믹싱스크류(135)로 공급되도록 공간을 구획한다. 격벽(132)은 소켓(131)의 가운데 영역에 배치된다. The partition wall 132 partitions the space such that the silicon base supplied to the first connector 133 and the second connector 134 and the curing agent are supplied to the mixing screw 135 without being mixed with each other. The partition 132 is disposed in the center region of the socket 131.
제1연결관(133)과 제2연결관(134)은 각각 베이스 배출관(112) 및 경화제 배출관(114)과 연결된다. 제1연결관(133)과 제2연결관(134)으로 공급된 실리콘 베이스와 경화제는 서로 독립적으로 믹싱스크류(135)로 배출된다. The first connector 133 and the second connector 134 are connected to the base discharge pipe 112 and the hardener discharge pipe 114, respectively. The silicone base and the hardener supplied to the first connector 133 and the second connector 134 are discharged to the mixing screw 135 independently of each other.
믹싱스크류(135)는 제1연결관(133)과 제2연결관(134)으로부터 공급받은 실리콘 베이스와 경화제가 상호 혼합되어 배출되도록 한다. 믹싱스크류(135)는 중심축(135a)과, 중심축(135a)의 판면에 나선방향으로 형성된 스크류날개(135b)를 포함한다. 실리콘 베이스와 경화제는 배출압력에 의해 스크류날개(135b)와 믹서수용관(123) 사이의 공간을 이동하며 서로 혼합되어 믹서수용관(123) 외부로 배출된다.

이러한 구성을 갖는 본 발명에 따른 인상재 카트리지 조립체(100)의 사용과정을 도 1 내지 도 4를 참조하여 설명한다. The use process of the impression material cartridge assembly 100 according to the present invention having such a configuration will be described with reference to FIGS. 1 to 4.
도 2에 도시된 바와 같이 믹싱팁(120) 내부에 믹서(130)를 수용하여 준비한다. 인상재 카트리지(110)의 한 쌍의 지지부(116)에 믹싱팁(120)의 접촉돌기(125)가 접촉되도록 위치를 정렬한다. 그리고, 믹싱팁(120)을 인상재 카트리지(110)에 가압하여 한 쌍의 지지부(116) 사이에 믹싱팁(120)이 끼워맞춤 되도록 한다. As shown in FIG. 2, the mixer 130 is accommodated in the mixing tip 120 and prepared. The position is aligned so that the contact protrusion 125 of the mixing tip 120 contacts the pair of supporting portions 116 of the impression material cartridge 110. Then, the mixing tip 120 is pressed against the impression material cartridge 110 so that the mixing tip 120 is fitted between the pair of supporting portions 116.
또한, 작업자는 한 쌍의 결합후크(124)의 누름판(124b)을 가압하여 후크본체(124d)의 걸림고리(124e)가 인상재 카트리지(110)의 상부플랜지(117)에 걸림결합되도록 한다. In addition, the operator presses the pressing plate 124b of the pair of coupling hooks 124 so that the hook 124e of the hook body 124d is engaged with the upper flange 117 of the impression material cartridge 110.
여기서, 상술한 두 가지 과정은 작업자의 한 번의 가압에 의해 동시에 이루어질 수 있다. 즉, 작업자가 결합후크(124)를 가압하면서 동시에 믹싱팁(120)을 한 쌍의 지지부(116) 사이에 끼워 삽입할 수 있다. 한 번의 가압 동작에 의해 인상재 카트리지(110)와 믹싱팁(120)의 결합과 분리가 이루어질 수 있으므로 작업자의 준비시간이 단축될 수 있다. Here, the above two processes can be performed simultaneously by one press of the operator. That is, the operator may press the coupling hook 124 while simultaneously inserting the mixing tip 120 between the pair of support portions 116. Coupling and separation of the impression material cartridge 110 and the mixing tip 120 can be made by a single pressurization operation, thereby reducing the preparation time of the operator.
한편, 인상재 카트리지(110)는 도 5에 도시된 바와 같이 캡(140)이 씌워진 상태로 보관된다. 캡(140)은 믹싱팁(120)에서 연결관(122)과 믹서수용관(123)의 구성이 빠진 형태로 구비된다. 믹싱팁(120)과 연결되기 전에는 인상재 카트리지(110)는 캡(140)에 씌워진 상태로 보관되고, 인상을 위해서는 캡(140)에서 분리된 후 믹싱팁(120)과 결합되어 사용된다.

이러한 구성을 갖는 본 발명에 따른 인상재 카트리지 조립체는 결합후크의 결합을 위한 한번의 조작 동작에 의해 간편하게 믹싱팁과 인상재 카트리지를 조립할 수 있다. 이에 의해 작업자의 작업과정을 단축시킬 수 있다. Impression material cartridge assembly according to the present invention having such a configuration can be easily assembled the mixing tip and the impression material cartridge by a single operation for the engagement of the coupling hook. This can shorten the work process of the worker.
또한, 믹싱팁과 인상재 카트리지가 지지판과 접촉돌기의 접촉에 의해 결합상태가 안정적으로 유지되므로 인상재의 누설을 방지할 수 있다.In addition, because the mixing tip and the impression material cartridge is maintained in a stable state by the contact of the support plate and the contact projection, it is possible to prevent the leakage of the impression material.
또한, 결합후크과 지지판에 의한 구속력이 믹싱팁 전영역에 고르게 분포되므로 믹싱팁의 좌우 및 상하 유동을 방지할 수 있다. In addition, since the restraint force by the coupling hook and the support plate is distributed evenly over the entire mixing tip, it is possible to prevent the left and right and the up and down flow of the mixing tip.
또한, 종래의 인상재 카트리지와 믹싱팁이 회전 결합하는 방식의 경우, 사용 후, 탈착시 경화된 인상재에 의해 믹서와 인상재 카트리지가 달라붙어 있어 믹싱팁의 회전이 매우 용이하지 않은 문제가 있는데, 본 발명은 카트리지와 믹싱팁이 후크결합하므로 인상재의 경화와 상관없이 매우 간단하게 믹싱팁을 인상재 카트리지로부터 탈착시킬 수 있다. In addition, the conventional impression material cartridge and the mixing tip is a rotary coupling method, after use, there is a problem that the mixer and the impression material cartridge is stuck by the impression material cured at the time of detachment, the rotation of the mixing tip is not very easy, the present invention Since the silver cartridge and the mixing tip are hooked together, the mixing tip can be detached from the impression material cartridge very simply regardless of the curing of the impression material.
