Abstract
본 고안은 음식물(내용물)을 내장한 용기속을 진공상태로 만들어 음식물(내용물)을 장시간 보관할 수 있도록 하고자 공기 펌프를 용기뚜껑에 구성시키고 용기속 공기를 뽑아내서 진공상태로 만들 수 있도록 고안된 "진공용기 뚜껑"에 관한 것이다The present invention is designed to vacuum the inside of the container containing the food (contents) to make food (contents) for a long time, and to configure the air pump in the container lid and extract the air in the container to be vacuumed Container lid "
본 고안에 따르면 용기뚜껑에 공기펌프를 구성시키고 용기속의 공기를 뽑아낼 수 있도록 하여 진공상태를 만들어 음식물은 장시간 보관할 수 있도록 하였고 또 음식물(내용물)을 꺼내고자 할때는 진공용기 뚜껑에 구성한 공기유입기를 조작시켜 진공용기 내로 공기를 유입시켜 진공상태를 와해시켜 뚜껑을 열 수 있도록 편리함을 제공하여 음식자원을 절약할 수 있고 음식을 장시간 보관할 수 있는 편리함을 제공한다According to the present invention, the air pump is formed on the lid of the container, and the air in the container can be extracted to create a vacuum state so that the food can be stored for a long time. It provides convenience to open the lid by breaking the vacuum state by introducing air into the vacuum container, saving food resources and providing convenience for storing food for a long time.
Description
본 고안은 진공용기 뚜껑(1)에 관한 것으로 도 1과 같이 진공용기 뚜껑(1)에 공기펌프 몸체(2)와 공기유입기 몸체(4)을 구성시키고 도 23과 같이 진공용기 뚜껑(1) 안쪽에 용기밀착판(27)을 설치시킨 다음 도 25와 같이 용기(28)에 진공용기 뚜껑(1)을 올려놓고 도 12와 같이 공기펌프 실린다 손잡이(3)를 화살방향으로 이동시키면 공기흡입구(8)로 용기내의 공기가 공기펌프의 공기실(9)로 빨려나온다이때 공기배출구(7)에 설치한 공기차단 벨브(14)는 닫치면서 공기실로 들어오는 공기를 막아준다The present invention relates to a vacuum container lid (1) to configure the air pump body (2) and the air inlet body (4) in the vacuum container lid (1) as shown in Figure 1 and the vacuum container lid (1) as shown in Figure 23 After the container contact plate 27 is installed inside, the vacuum container lid 1 is placed on the container 28 as shown in FIG. 25, and the air pump is loaded as shown in FIG. 12. 8) When the air in the container is sucked into the air chamber (9) of the air pump, the air shutoff valve (14) installed in the air outlet (7) closes to prevent the air entering the air chamber.
이 상태에서 도 13과 같이 공기펌프의 실린다 손잡이(13)를 화살방향으로 다시 이동시키면 공기실(9)에 있던 공기가 공기배출구(7)를 통해 외부공기 배출구(10)로 통해 배출되어 나간다In this state, as shown in FIG. 13, when the handle 13 of the air pump is moved again in the direction of the arrow, the air in the air chamber 9 is discharged through the air outlet 7 to the outside air outlet 10.
이때는 공기흡입구(8)에 설치한 공기차단 벨브(14)는 닫치면서 용기내로 공기유입을 막아준다 이렇게 수회 계속하면 용기내의 공기가 빠저나오게 된다 이때 진공용기 뚜껑(1)에 설치한 용기 밀착판(27)은 외부에서 용기속으로 유입되는 공기를 막아주게 되고 용기속은 진공상태로 만들어지면서 진공용기 뚜껑(1)은 열리지 않게 된다At this time, the air shutoff valve 14 installed at the air inlet 8 is closed to prevent the inflow of air into the container. If this is continued several times, the air in the container comes out. At this time, the container contact plate installed on the vacuum container lid 1 27) prevents the air flowing into the container from the outside and the container is made in a vacuum state, the vacuum container lid (1) is not opened.
진공용기 뚜껑을 열고자 할때는 도 20과 같은 상태의 공기유입기 손잡이(5) 이를 도 21과 같이 눕히면 공기차단 벨브판(23)이 위로 올라 가면서 공기유입구(12)를 열어주게 되고 이때 용기속으로 공기가 화살표와 같이 유입되고 진공용기 뚜껑(1)이 열리게 된다When opening the lid of the vacuum container, the air inlet handle 5 in the state as shown in FIG. 20 is laid down as shown in FIG. Air flows in as shown by the arrow and the vacuum container lid 1 is opened.
그러나 종래의 용기뚜껑은 용기내의 내용물을 보호하는 수단으로 잠금 장치를 부착 하였을 뿐이다 따라서 종래의 용기로서는 음식물(내용물)을 장시간 보관할 수 없는 결점이 있었다However, the conventional container lid only has a locking device as a means of protecting the contents of the container. Therefore, the conventional container lid has a drawback in that food (content) cannot be stored for a long time.
본 고안의 목적은 용기속을 간단한 방법으로 진공상태로 만들어 음식물을 장시간 보관시키고자 함에 그 목적이 있는 바 도 1, 2와 같은 진공용기 뚜껑(1)에 공기펌프 몸체(2)와 공기유입 몸체(4)를 구성시켜 도 23과 같이 공기펌프와 공기유입기(4)를 완성시키고 도 12, 13과 같이 공기펌프 실린다 손잡이(3)를 좌,우로 움직여서 공기흡입구(8)와 공기배출구(7)를 통해 용기속의 공기를 뽑아내서 진공상태로 만들기도 하고 도 21과 같이 공기유입기 손잡이(5)를 조작하여 진공상태인 용기속으로 공기를 유입시켜 용기 뚜껑을 열 수 있도록 편리함을 제공하도록 하였다The purpose of the present invention is to make the vacuum in the container in a simple way to store food for a long time, the purpose of the air pump body (2) and the air inlet body in the lid of the vacuum container (1) as shown in Figs. (4) to complete the air pump and the air inlet (4) as shown in Figure 23 and air pump loaded as shown in Figures 12 and 13 by moving the handle (3) to the left and right air inlet (8) and air outlet (7) By extracting the air in the container to make a vacuum state through the) and to operate the air inlet handle (5) as shown in Figure 21 to provide the convenience to open the container lid by introducing air into the container in a vacuum state

본 고안에 따르면 용기 뚜껑(1)에 도 1, 2와 같이 공기펌프 몸체(2)를 구성시키고 그 내부에는 도 2, 3, 4와 같이 공기흡입구(8)와 공기배출구(7)를 공기실(9)에 구성시키고 도 3과 같은 공기흡입구(8)에 도 5와 같은 공기차단벨브(14)를 도 6과 같이 설치하며 도 4와 같은 공기배출구(7)에도 도 5와 같은 공기차단벨브(14)를 도 7과 같이 설치한다 도 9와 같은 공기펌프 실린다(16)에 도 10과 같은 공기펌프 실린다링(18)을 도 11과 같이 결합하여 도 8과 같은 공기펌프 스프링(15)을 함께 하여 공기펌프 공기실(9)에 도 23과 같이 설치한다According to the present invention, the air cap body 2 is configured in the container lid 1 as shown in FIGS. 1 and 2, and the air inlet 8 and the air outlet 7 are provided in the air chamber as shown in FIGS. 2, 3 and 4. The air blocking valve 14 as shown in FIG. 5 is installed in the air inlet 8 as shown in FIG. 3, as shown in FIG. 6, and the air blocking valve as shown in FIG. Install the air pump spring 15 as shown in FIG. 8 by attaching the air pump seal ring 18 as shown in FIG. 10 to the air pump seal 16 as shown in FIG. Together with the air pump in the air chamber (9) as shown in Figure 23
이와 같이 구성한 후 공기펌프 실린다 손잡이(3)를 도 12와 같이 화살 방향으로 이동시키면 공기흡입구(8)를 통해 용기속의 공기가 화살표와 같은 방법으로 공기펌프 공기실(9)로 유입된다After this configuration, the air pump is loaded. When the knob 3 is moved in the direction of the arrow as shown in FIG. 12, the air in the container is introduced into the air pump air chamber 9 in the same way as the arrow through the air inlet 8.
이러한 상태에서 도 13과 같이 공기펌프 실린다(16)를 화살표 방향으로 이동시키면 공기실에 있던 공기는 공기배출구(7)를 통해 화살표와 같은 방법으로 공기펌프 박으로 배출된다In this state, as shown in FIG. 13, when the air pump seal 16 is moved in the direction of the arrow, the air in the air chamber is discharged to the air pump foil through the air outlet 7 in the same way as the arrow.
이러한 동작을 계속하면 용기속은 진공으로 되고 용기뚜껑은 열리지 않는다사용하기 위해 용기뚜껑을 열고자 할 때는 진공 용기속으로 공기를 유입시키기 위해 도 1, 2와 같이 공기유입기 몸체(4)를 용기뚜껑(1)에 구성하고 도 15와 같은 공기유입기 실린다(19)에 도 16과 같은 공기유입기 공기 차단 벨브판(23)을 도 17과 같이 결합한 다음 도 18과 같은 공기유입기 스프링(25)을 함께하여 공기유입기 몸체(4)에 결합하여 도 20과 같이 만들고 공기유입기 손잡이(5)를 도 21과 같이 눕히면 공기유입기 실린다(19)는 위로 올라가고 공기유입구(12)가 열리게 되어 공기가 화살표 방향과 같은 방법으로 진공상태의 용기속으로 유입되면서 용기뚜껑을 열 수 있게 된다.If this operation continues, the container becomes a vacuum and the container lid does not open. When the container lid is opened for use, the air inlet body 4 is opened as shown in FIGS. 1 and 2 to introduce air into the vacuum container. The air inlet air blocking valve plate 23 of FIG. 16 is coupled to the air inlet spring 19 of FIG. 15 and the air inlet spring 25 of FIG. In combination with the air inlet body (4) as shown in Figure 20 and the air inlet handle (5) laid down as shown in Figure 21, the air inlet is loaded 19 and the air inlet 12 is opened to open the air In the same way as the arrow flows into the container in a vacuum state it is possible to open the container lid.
이상에서와 같이 본 고안에 의하면 용기속의 음식물(내용물)을 진공상태에서 장시간 보관할 수 있는 효과를 얻게되고 항상 신선한 음식을 먹을 수 있어 국민건강 유지에 좋은 효과가 될 것이며 음식을 상해서 버리는 경우가 없게되어 음식자원이 절략되는 효과를 얻게 된다As described above, according to the present invention, the effect of storing food (contents) in a container for a long time in a vacuum state is obtained, and it is possible to always eat fresh food, which is a good effect for maintaining the national health, and there is no case of spoiling food. Food resources are cut down
