에어리스 펌프식 화장품용기의 펌프구조{Cosmiatic vessel with airless pump}Pump structure of airless pump cosmetic container {Cosmiatic vessel with airless pump}

본 발명은 에어리스 펌프식 화장품용기의 펌프구조에 관한 것으로, 더욱 상세하게는 에어리스 펌프를 제작시 상부캡 내부에는 스템부를 일체로 형성하고 하부캡 내부에는 실린더부를 일체로 형성 하므로써, 부품수를 줄여 조립 생산성을 증대시킴은 물론 용기내의 내용물이 역류되는 것을 방지하고 체크밸브와 실린더부 바닥면과의 밀착력을 증대시켜 체크밸브가 제 기능을 계속적으로 수행할 수 있도록 한 에어리스 펌프식 화장품용기의 펌프구조에 관한 것이다.The present invention relates to a pump structure of an airless pump-type cosmetic container, and more particularly, when manufacturing the airless pump, the stem part is integrally formed inside the upper cap and the cylinder part is integrally formed inside the lower cap, thereby reducing the number of parts. The pump structure of the airless pump type cosmetics container which not only increases the productivity but also prevents the contents in the container from flowing backward and increases the adhesion between the check valve and the bottom of the cylinder part so that the check valve can continue its function. It is about.

일반적으로 액체 또는 겔상태의 화장품을 저장보관토록 하는 화장품용기는 그 주입구상에 내용물을 외부로 원활하게 배출시키도록 펌핑수단이 설치된다. 이러한 화장품용기의 펌프는 내용물을 일정량씩 외부로 배출하는 기능을 가짐으로써 사용의 편리성을 도모하고 또한 내용물의 과다한 배출을 억제하여 낭비를 줄이도록 하는 것으로, 지금까지도 여러 가지 구조가 제안되어 널리 사용되고 있다. Generally, a cosmetic container for storing and storing a liquid or gel cosmetics is provided with a pumping means to smoothly discharge the contents to the outside on the injection port. The pump of the cosmetic container has a function of discharging the contents by a certain amount to the outside to promote convenience of use and to reduce waste by suppressing excessive discharge of the contents, and various structures have been proposed and widely used until now. have.

상기 펌프의 대체적인 원리는 하부캡의 하단에 용기가 결합되고 상단에는 상부캡이 연결 조립된 상태에서 상부캡의 펌핑동작에 따라 상하 왕복운동하는 피스톤 에 의해 내용물유입구에 위치한 체크밸브가 선택적으로 개폐되면서 용기내에 수용된 내용물이 노즐을 통해 일정량씩 외부로 토출되는 것이다.The general principle of the pump is that the container is coupled to the lower end of the lower cap and the upper cap is connected to the upper cap and the check valve located at the contents inlet is selectively opened and closed by a piston reciprocating up and down according to the pumping operation of the upper cap. While the contents contained in the container is discharged to the outside by a predetermined amount through the nozzle.

상기와 같은 펌핑수단은 에어리스 펌프타입으로써 화장품용기에 널리 사용되나, 종래에는 주요 구성품인 스템과 실린더가 각기 별도로 제작된 후, 상부캡 내부에는 스템이 위치하고 하부캡 내부에는 실린더가 조립 사용된다. The pumping means as described above is an airless pump type, widely used in cosmetic containers, but conventionally, after the stem and cylinder are manufactured separately, the stem is located inside the upper cap and the cylinder is used inside the lower cap.

따라서 종래에는 상부캡, 스템, 실린더, 하부캡이 별도의 구성부품으로 제작 사용되기 때문에 조립 생산성이 크게 저하될 뿐 아니라, 정확한 조립이 되지 않을시에는 효과적으로 공기가 압축되지 않는 단점이 있었다. 여기서, 스템은 피스톤을 지지 고정하여 피스톤이 용이하게 실린더 내부를 움직이게 하는 역할을 수행한다.Therefore, in the related art, since the upper cap, the stem, the cylinder, and the lower cap are manufactured and used as separate components, as well as the assembly productivity is greatly reduced, there is a disadvantage in that air is not effectively compressed when the assembly is not performed correctly. Here, the stem serves to support and fix the piston so that the piston easily moves inside the cylinder.

한편, 종래 펌프구성에는 용기가 눌렸을 때 패킹이 강제로 밀리는 것을 방지하는 별도의 장치가 마련되어 있지 않기 때문에 외부의 간섭등에 의해 용기가 눌렸을 때 패킹이 강제로 밀리면서 용기 내부에 수용된 내용물이 역류되는 단점이 있었다.On the other hand, the conventional pump configuration does not have a separate device that prevents the packing is forcibly pushed when the container is pressed, the packing is forcibly pushed when the container is pressed by external interference, etc., the contents contained inside the container flow back There was a disadvantage.

또한, 종래 에어리스 펌프에 있어서 펌핑시 체크밸브가 개폐되면서 용기내에 수용된 내용물이 노즐을 통해 일정량씩 외부로 토출되도록 되어 있다. 그러나 종래 에어리스 펌프 구성에는 체크밸브와 실린더 바닥면과의 밀착력(압축력)을 증대시킬 수 있는 별도의 장치가 마련되어 있지 않기 때문에 장기간 사용시 체크밸브의 밀착력이 저하되어 체크밸브의 기능을 수행하지 못하는 등의 제반 문제점이 있었다. In addition, in the conventional airless pump, the contents contained in the container are discharged by a predetermined amount through the nozzle while the check valve is opened and closed when pumping. However, the conventional airless pump does not have a separate device that can increase the adhesion (compression force) between the check valve and the bottom of the cylinder. There was a whole problem.

본 발명의 목적은 상기와 같은 제반 문제점을 감안하여 안출한 것으로 에어리스 펌프를 제작시 상부캡 내부에는 스템부를 일체로 형성하고 하부캡 내부에는 실린더부를 일체로 형성 하므로써, 부품수를 줄여 조립 생산성을 증대시킬 수 있도록 한 에어리스 펌프식 화장품용기의 펌프구조를 제공하는 데 있다.An object of the present invention is to devise in view of the above-mentioned problems, and when manufacturing the airless pump to form a stem portion integrally in the upper cap and a cylinder portion integrally in the lower cap, to reduce the number of parts to increase the assembly productivity It is to provide a pump structure of an airless pump-type cosmetic container that can be made.

본 발명의 다른 목적은 실린더부 내벽 상단에 외부로 돌출되는 돌기를 형성한 후, 용기가 눌렷을 때 상기 돌기를 통하여 패킹이 밀리는 것을 방지하여 용기내의 내용물이 역류되는 것을 미연에 차단할 수 있도록 한 에어리스 펌프식 화장품용기의 펌프구조를 제공하는 데 있다.Another object of the present invention is to form an protrusion projecting outward on the inner wall of the cylinder portion, the airless to prevent the packing from being pushed through the protrusion when the container is pressed to prevent the back flow of the contents in the container in advance. It is to provide a pump structure of a pump cosmetic container.

본 발명의 또 다른 목적은 내용물유입구와 체크밸브 사이에 고무재질의 체크실링을 형성한 후, 상기 체크실링을 통하여 항상 체크밸브가 실린더부 바닥면과의 밀착력(압축력)이 증대되게 하므로써, 펌프 펌핑시 항상 체크밸브가 밀착력을 유지한 상태에서 계속적으로 제 기능을 수행할 수 있도록 한 것이다. Still another object of the present invention is to form a check seal of rubber material between the contents inlet port and the check valve, and then the check valve always increases the adhesion (compression force) with the bottom surface of the cylinder through the check seal, thereby pumping the pump. It is to ensure that the check valve is able to continue functioning at all times while maintaining close contact force.

본 발명은 상기와 같은 목적을 달성하기 위한 수단으로 상부캡과 하부캡을 성형시 상기한 상부캡 내부에는 스템부가 일체로 형성되고, 하부캡 내부에는 실린더부가 일체로 형성되어 스템부 및 실린더 역할을 수행토록 하는 것과,The present invention when forming the upper cap and the lower cap as a means for achieving the above object, the stem portion is formed integrally inside the upper cap, the cylinder portion is formed integrally inside the lower cap to act as the stem portion and the cylinder To do it,

실린더부 내벽 상단에 외부로 돌출되는 돌기를 형성한 후, 용기를 눌렀을 때 상기 돌기를 통하여 패킹이 밀리는 것을 방지하여 용기내의 내용물이 역류됨을 방 지하는 것과,After forming a projection projecting to the outside on the top of the inner wall of the cylinder, preventing the contents of the container from flowing backward by preventing the packing from being pushed through the projection when the container is pressed,

내용물유입구와 체크밸브 사이에 고무재질의 체크실링을 형성한 후, 상기 체크실링을 통하여 체크밸브가 실린더부 바닥면과의 밀착력이 증대되게 하는 것을 그 기술적 구성상의 기본 특징으로 한다.After forming the check seal of the rubber material between the contents inlet and the check valve, the check valve is to increase the adhesion between the check valve and the bottom surface of the cylinder through the check seal is a technical feature of the technical configuration.

이상에서 살펴본 바와 같이 본 발명에 따르면, 에어리스 펌프를 제작시 상부캡 내부에는 스템부가 일체로 형성되어 있고, 하부캡 내부에는 실린더부가 일체로 형성되어 있다. 따라서 종래와 같이 스템 및 실린더 기능을 하는 별도의 부품을 제작한 후, 이를 조립하지 않아도되기 때문에 부품수가 줄어 조립 생산성이 크게 증대될 수 있는 것이다.As described above, according to the present invention, the stem part is integrally formed inside the upper cap when the airless pump is manufactured, and the cylinder part is integrally formed inside the lower cap. Therefore, after manufacturing a separate part that functions as a stem and a cylinder as in the prior art, it is not necessary to assemble it, so the number of parts can be reduced and assembly productivity can be greatly increased.

또한, 본 발명은 실린더부 내벽 상단에 외부로 돌출되는 돌기가 형성되어 있다. 따라서 외부의 간섭등에 의해 용기가 눌렷을 때 패킹은 돌기에 의해 밀리는 것이 방지되므로 용기내의 내용물이 역류되는 것이 방지되는 것이다.In addition, the present invention is formed with a protrusion projecting to the outside on the upper end of the inner wall of the cylinder portion. Therefore, when the container is pressed by external interference, the packing is prevented from being pushed by the projections so that the contents in the container are prevented from flowing back.

또한, 본 발명은 내용물유입구와 체크밸브 사이에 고무재질의 체크실링이 형성되어 있다. 따라서 체크실링을 통하여 항상 체크밸브가 실린더부 바닥면과의 밀착력(압축력)을 유지한 상태이기 때문에 체크밸브는 계속적으로 제 기능을 수행할 수 있는 등의 효과가 있는 것이다. In the present invention, a check seal made of rubber material is formed between the contents inlet port and the check valve. Therefore, the check valve is always in close contact with the bottom surface of the cylinder (compression force) through the check seal has the effect that the check valve can continue to function properly.

이하 본 발명의 바람직한 실시예를 첨부도면을 참조하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명에 따른 에어리스 펌프식 화장품용기의 펌프구조를 나타낸 구성도 이고, 도2는 본 발명에 따른 에어리스 펌프식 화장품용기의 펌프의 요부확대 단면도이다. 1 is a configuration diagram showing the pump structure of the airless pump-type cosmetic container according to the present invention, Figure 2 is an enlarged cross-sectional view of the main portion of the pump of the airless pump-type cosmetic container according to the present invention.

본 발명의 에어리스 펌프식 화장품용기의 펌프구조는 하부캡(110)의 하단에 용기(170)가 결합되고 상단에는 상부캡(100)이 연결 조립된 상태에서 상부캡(100)의 펌핑동작에 따라 상하 왕복운동하는 피스톤(120)에 의해 내용물유입구(140)에 위치한 체크밸브(130)가 선택적으로 개폐되면서 용기(170)내에 수용된 내용물이 노즐(150)측으로 토출되게 하는 기본적인 맥락은 종래와 같다.Pump structure of the airless pump-type cosmetic container of the present invention according to the pumping operation of the upper cap 100 in a state in which the container 170 is coupled to the lower end of the lower cap 110 and the upper cap 100 is connected and assembled at the upper end. While the check valve 130 positioned at the contents inlet 140 is selectively opened and closed by the piston 120 vertically reciprocating, the basic context for discharging the contents contained in the container 170 to the nozzle 150 is the same as in the related art.

다만, 본 발명은 더욱 효과적으로 화장품용기 내부에 수용된 내용물을 펌핑할 수 있도록 한 것으로 이는 도1 내지 도2에서와 같이 상부캡(100)과 하부캡(110)을 성형시 상기한 상부캡(100) 내부에는 스템부(200)가 일체로 형성되고, 하부캡 (110)내부에는 실린더부(300)를 일체로 형성하였다. 이와 같은 스템부(200) 및 실린더부(300)는 종래 스템 및 실린더와 같이 동일한 역할을 수행하도록 구성된다.However, the present invention to more effectively pump the contents contained in the cosmetic container, which is the upper cap 100 when forming the upper cap 100 and the lower cap 110 as shown in Figure 1 to Figure 2 The stem part 200 is formed integrally inside, and the cylinder part 300 is integrally formed inside the lower cap 110. The stem portion 200 and the cylinder portion 300 is configured to perform the same role as the conventional stem and cylinder.

이와 같이 스템부(200)와 실린더부(300)가 일체로 형성된 상태에서는 부품수를 줄이는 효과가 있을 뿐 아니라, 조립시 정확한 조립이 가능하기 때문에 공기의 압축효과를 얻을 수 있으며, 조립시 생산성이 크게 향상된다.As such, the stem part 200 and the cylinder part 300 are integrally formed so that not only the number of parts can be reduced, but also accurate assembly can be achieved during assembly, so that a compression effect of air can be obtained. Greatly improved.

조립된 후에는 피스톤(120) 상단이 스템부(200)에 삽입 고정되어 있고, 하단은 실린더부(300) 내부에 위치하여 상하 왕복운동할 수 있도록 되어 있으며, 펌핑 방법은 종래와 같다. After assembly, the upper end of the piston 120 is fixed to the stem portion 200, the lower end is located in the cylinder portion 300 to be able to reciprocate up and down, the pumping method is the same as the conventional.

한편, 실린더부(300) 제작시 실린더부(300) 내벽 상단에 외부로 돌출되는 돌 기(500)를 형성하였다. 이는 외부의 간섭 등에 의해 용기(170)가 눌렸을 때 상기 돌기(500)가 패킹(160)이 밀리는 것을 방지하기 때문에 용기(170)내의 내용물이 역류되는 것이 방지된다.On the other hand, during the production of the cylinder part 300, a protrusion 500 protruding outward was formed on the inner wall top of the cylinder part 300. This prevents the contents of the container 170 from flowing back because the protrusions 500 prevent the packing 160 from being pushed when the container 170 is pressed by external interference or the like.

또한, 내용물유입구(140)와 체크밸브(130) 사이에 고무재질의 체크실링(400)이 형성된다. 이와 같은 구성은 연속적인 펌핑이 이루어지더라도 체크밸브(130)는 상기 체크실링(400)을 통하여 실린더부(300) 바닥면과의 밀착력을 계속적으로 유지할 수 있으며, 이것에 의해 체크밸브(130)는 제 기능을 수행할 수 있는 것이다.In addition, a check seal 400 of rubber material is formed between the contents inlet 140 and the check valve 130. Such a configuration allows the check valve 130 to continuously maintain adhesion to the bottom surface of the cylinder part 300 through the check seal 400 even though continuous pumping is performed, whereby the check valve 130 Can do its job.
