이하, 첨부도면을 참조하여 본 발명의 바람직한 실시예를 구체적으로 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도2 내지 도8에 도시되듯이, 교체용 내부용기가 수납되어 있는 진공용기(10)는 크게 외부용기(20), 내부용기(30), 뚜껑(40) 및 패킹(50)으로 이루어지고 내부용기(20)는 종이컵, 컵라면 등과 같이 일회용 용기의 소재가 사용될 수 있다. 이에 따라 사용 후에 내부용기(20)는 교체되어, 진공용기(10)는 항상 청결하고 위생적인 상태로 유지된다.As shown in Figures 2 to 8, the vacuum container 10 in which the replacement inner container is accommodated largely consists of the outer container 20, the inner container 30, the lid 40 and the packing 50 and the inside The container 20 may be a material of a disposable container such as paper cups, cup noodles, and the like. Accordingly, after use, the inner container 20 is replaced so that the vacuum container 10 is always kept clean and sanitary.
상기 외부용기(20)는 종래의 진공용기와 동일, 유사하게 내부에 오목부(24)가 형성된 그릇형태이다. 외부용기(20)는 스테인레스 스틸, 단단한 플라스틱 소재 등으로 이루어져, 내부가 진공이 되더라도 대기압에 의해 변형되지 않고 외관이 유지된다.The outer container 20 is in the form of a vessel in which a recess 24 is formed inside, similarly to a conventional vacuum container. The outer container 20 is made of stainless steel, a hard plastic material, etc., even if the inside is vacuum, the appearance is maintained without being deformed by atmospheric pressure.
상기 내부용기(30)는 얇고 유연한 소재로 이루어진다. 그리고, 내부용기(30)의 강도가 약하더라도 외부용기(20)의 내부에 위치되어, 진공시에 대기압에 의해 변형되지 않게 된다. 예를 들면 내부용기(30)는 종이컵의 소재, 컵라면등의 스티로폼 소재 등이 사용될 수 있어, 저렴하게 대량으로 생산될 수 있다.The inner container 30 is made of a thin and flexible material. Further, even if the strength of the inner container 30 is weak, it is located inside the outer container 20 so that it is not deformed by atmospheric pressure during vacuum. For example, the inner container 30 may be a material of a paper cup, a styrofoam material such as cup noodle, etc., and thus may be inexpensively produced in large quantities.
바람직하게는 도5에 도시되듯이 불규칙하고 독립적인 다수의 엠보싱(33)이 상기 내부용기(30)의 외부측 측면(32), 하부(34)의 전부 또는 일부에 형성되어, 외부용기(20)와 내부용기(30) 사이에 틈새(23, 도3)가 확보된다. 이와 같은 틈새(23)에 의하여 진공시 틈새(23)의 공기와 내부용기(30)의 내부 공기가 함께 배출되어, 내부용기(30)의 요동과 변형이 방지된다.Preferably, as shown in FIG. 5, a plurality of irregular and independent embossings 33 are formed on all or a part of the outer side 32 and the lower part 34 of the inner container 30, thereby forming the outer container 20. ) And a clearance 23 (FIG. 3) is secured between the inner container 30. By the gap 23, the air of the gap 23 and the internal air of the inner container 30 are discharged together in the vacuum, thereby preventing the shaking and deformation of the inner container 30.
도6 내지 도8에는 상기 내부용기(30)의 다른 실시형태가 도시되어 있다. 도6에서 다수의 연속적인 수직돌기(35)가 상기 내부용기(30)의 외부, 특히 측면(32)과 하부(34)의 전부 또는 일부에 형성되어, 상기 수직돌기(35) 사이에는 틈새(23, 도3)가 확보된다. 경우에 따라서는 상기 수직돌기(35)와 반대로 음각될 수 있다. 예를 들어 도7 및 도8에 도시되듯이 다수의 연속적인 오목한 홈으로 된 채널(38)이 상기 내부용기(30)의 외부, 특히 측면(32)과 하부(34)의 전부 또는 일부에 형성되어, 상기 홈에 의해 틈새(23, 도3)가 확보될 수도 있다.6 to 8 show another embodiment of the inner container 30. In FIG. 6, a plurality of continuous vertical protrusions 35 are formed on the outside or in particular all or part of the side surface 32 and the lower portion 34 of the inner container 30, so that a gap (between the vertical protrusions 35) is formed. 23, Fig. 3) is secured. In some cases, it may be engraved as opposed to the vertical protrusion 35. 7 and 8, for example, a plurality of continuous concave grooved channels 38 are formed on the exterior of the inner container 30, in particular on all or part of the side 32 and bottom 34. Thus, the gap 23 (Fig. 3) may be secured by the groove.
상기 뚜껑(40)은 음식물 등이 진공용기(10)의 내부로 수납되고 상기 외부용기의 상부(21)에 덮히어, 밀폐된 공간을 형성하게 된다. 상기 뚜껑(40)에는 진공밸브(41)가 형성되어, 내부와 외부를 연결하는 공기유출입통로를 개폐한다. 진공시에는 상기 진공밸브(41)가 열리고 진공펌프(도시안됨)를 통해 진공용기(10)의 내부공기가 배출된다. 그리고, 진공된 후에는 진공밸브(41)가 닫힌 상태로 유지되고, 진공해제하여 뚜껑(40)을 열 경우에 먼저, 진공밸브(41)가 열려 대기와 진공용기(10)의 내부가 연결되고, 내부용기(30)의 내부 진공이 해제된다. 이에 따라 내부패킹(53)와 내부용기의 상부(31)가 서로 떨어지고, 상기 틈새(23)도 엠보싱(33), 수직돌기(35) 또는 채널(38)에 의하여 대기와 연결되어, 틈새(23)의 진공도 해제된다.The lid 40 has food or the like accommodated inside the vacuum container 10 and is covered by the upper portion 21 of the outer container, thereby forming a closed space. A vacuum valve 41 is formed on the lid 40 to open and close the air outlet passage connecting the inside and the outside. In the vacuum, the vacuum valve 41 is opened and the internal air of the vacuum container 10 is discharged through the vacuum pump (not shown). After the vacuum, the vacuum valve 41 is kept in a closed state, and when the lid 40 is opened by releasing the vacuum, first, the vacuum valve 41 is opened, and the atmosphere and the interior of the vacuum container 10 are connected. The internal vacuum of the inner container 30 is released. Accordingly, the inner packing 53 and the upper portion 31 of the inner container are separated from each other, and the gap 23 is also connected to the atmosphere by the embossing 33, the vertical protrusion 35, or the channel 38, and the gap 23. ) Vacuum is also released.
이와 같은 진공밸브(41)는 다양한 형태가 사용될 수 있으며, 예를 들면 도1에 도시된 종래기술의 진공밸브가 사용될 수도 있다. 도1에 도시된 진공밸브에서는 내부 공기가 구멍(18, 도1)과, 밸브의 측면 틈새를 걸쳐 외부 대기로 배출되고, 진공시에는 진공압에 의하여 스스로 밀폐된다. 그리고, 투명판(26, 도1)은 힌지(22, 도1)를 중심으로 개폐된다.Such a vacuum valve 41 may be used in various forms, for example, the vacuum valve of the prior art shown in Figure 1 may be used. In the vacuum valve shown in Fig. 1, the internal air is discharged to the outside atmosphere through the holes 18 (Fig. 1) and the lateral gap of the valve, and is sealed by vacuum pressure at the time of vacuum. The transparent plate 26 (FIG. 1) is opened and closed about the hinge 22 (FIG. 1).
상기 패킹(40)이 상기 외부용기(20)의 상부(21)에 맞닿는 상기 뚜껑(40)의 하부(42)에 따라 형성되어 있어, 진공용기(10)의 내부 밀폐가 정확하고 용이하게 된다. 바람직하게는 상기 패킹(40)의 소재는 실리콘 소재로 이루어진다.The packing 40 is formed along the lower portion 42 of the lid 40 in contact with the upper portion 21 of the outer container 20, so that the inner sealing of the vacuum container 10 is accurate and easy. Preferably, the material of the packing 40 is made of a silicon material.
구체적으로 상기 패킹(40)은 대체로 도우넛 형태이고, 그 단면은 도4에 도시되듯이 단차(d)진 외부패킹(52)과 내부패킹(53)으로 이루어진다. 상기 외부패킹(52)은 상기 패킹의 하부(42)에서 하방으로 돌출형성되며 상기 뚜껑의 하부(42)를 빙둘러싸며, 상기 내부패킹(53)은 상기 외부패킹(52)보다 내부로 이격되어 돌출되어, 상기 외부패킹(52)보다 낮게 단차가 형성된다. 경우에 따라서는 상기 패킹의 하부는 계단형태의 단차(d)로 형성될 수 있다.Specifically, the packing 40 is generally in the form of a doughnut, and its cross section is composed of an outer packing 52 and an inner packing 53 having a step d as shown in FIG. The outer packing 52 protrudes downward from the lower part 42 of the packing and surrounds the lower part 42 of the lid, and the inner packing 53 is spaced inward from the outer packing 52. Protruding, the step is formed lower than the outer packing (52). In some cases, the lower portion of the packing may be formed in a stepped step d.
상기 단차(d)가 형성되어, 외부패킹(52)가 외부용기의 상부(21)와 처음 맞닿은 때에, 내부패킹(53)은 내부용기의 상부(31)는 아직 맞닿지 않게 된다. 이에 의하여, 진공의 초기에 외부패킹(52)만 상기 외부용기의 상부(21)와 맞닿아, 진공용기(10)의 내부가 밀폐되고, 틈새(23)는 개방된다. 그리고 어느 정도 시간이 경과되어 소정의 진공도가 형성되면 상기 외부패킹(52)이 압착되어 내부패킹(53)이 상기 내부용기의 상부(31)에 맞닿게 되어, 틈새(23)가 밀폐된다. 나아가 상기 틈새(23)가 밀폐되어, 진공포장이 완료된 후에 진공용기(10)가 보관되더라도 내부용기(30)가 외부용기(20)에 고정되고, 틈새(23)로 이물질이 들어가지 않게 된다.The step d is formed so that when the outer packing 52 first contacts the upper part 21 of the outer container, the inner packing 53 is not yet in contact with the upper part 31 of the inner container. As a result, only the outer packing 52 contacts the upper portion 21 of the outer container at the initial stage of the vacuum, so that the inside of the vacuum container 10 is sealed, and the gap 23 is opened. When a predetermined degree of vacuum is formed after a certain time has elapsed, the outer packing 52 is compressed, and the inner packing 53 comes into contact with the upper part 31 of the inner container, thereby closing the gap 23. Furthermore, the gap 23 is sealed, and even though the vacuum container 10 is stored after the vacuum packing is completed, the inner container 30 is fixed to the outer container 20, and foreign matter does not enter the gap 23.
도9 및 도10에는 본 발명의 다른 실시예에 의한 진공용기(10)가 도시되어 있다. 도9에 도시된 진공용기(10)에서는 외부용기(20)의 상부(21)는 플랜지 형태로 형성되고 이 플랜지의 상면에 또한 플랜지 형태인 내부용기(30)의 상부(21)가 위치되고, 단차(d, 도4)는 상기 내부용기의 두께보다 충분히 크게 이루어진다. 그외 구성은 도3에 도시된 진공용기(10)와 동일, 유사하다.9 and 10 illustrate a vacuum vessel 10 according to another embodiment of the present invention. In the vacuum container 10 shown in FIG. 9, the upper portion 21 of the outer container 20 is formed in the form of a flange, and the upper portion 21 of the inner container 30, which is also in the form of a flange, is positioned on the upper surface of the flange. Step (d, Fig. 4) is made larger than the thickness of the inner container. The rest of the configuration is the same as or similar to that of the vacuum container 10 shown in FIG.
도10에 도시된 진공용기(10)에서는 패킹(50)의 하부가 평평하게 형성되고, 반면에 단차(d, 도4)가 내부용기의 상부(31)와 외부용기의 상부(21)의 높낮이로 형성된다. 구체적으로 상기 외부용기의 상부(21)가 상기 내부용기의 상부(31)보다 조금 높게 단차가 지도록 상기 외부용기의 상부(21)와 상기 내부용기의 상부(31)가 형성된다. 그외 구성은 도3에 도시된 진공용기(10)와 동일, 유사하다.In the vacuum container 10 shown in Fig. 10, the lower part of the packing 50 is formed flat, while the step d, Fig. 4 is the height of the upper part 31 of the inner container and the upper part 21 of the outer container. Is formed.
