Description

Lid for airtight container and airtight container with same

The present invention is closed and closed automatically by the elastic force of the spring to periodically discharge the gas generated from the food stored in the sealed container and having a gas discharge mechanism having a function to deodorize so that the odor component contained in the gas does not leak out It relates to a lid for a container and a sealed container having the same.

Homes and restaurants generally use different types of containers to store and store food ingredients, semi-cooked or cooked foods. In particular, fermented foods such as kimchi, soybean paste, red pepper paste, lactose, and fruit liquor should be stored in a closed container with aging for a long period of time. If gas from fermented food continues to accumulate in the sealed container, the pressure inside the sealed container increases, which may cause food leakage between the lids of the sealed container and deterioration of the food exposed to the outside air. There is a risk of ground explosion.

In order to solve such a problem, an invention regarding a gas discharge structure of a food container that automatically discharges gas generated from fermented food has been proposed.

However, the conventional gas discharge structure has a function of periodically discharging the gas accumulated in the container, but especially when the food having a specific smell such as fermented food or fish is stored in the container, even the odor component contained in the gas is taken out. There is a problem to discharge. This can be said to be contrary to the basic function of the sealed container, and if the sealed container is stored in a narrow space such as a refrigerator, it causes a problem that even other stored foods are contaminated with odor.

In addition, the conventional gas discharge structure is generally provided with an intake hole and an exhaust hole as a passage for discharging the gas inside the container to the outside, and the intake hole disposed on the container side is disposed directly above the stored food, so that the exhaust hole contacts the food. There is a problem that is very likely to be. In other words, there is a problem that the function of the gas exhaust structure is lost by the intake hole is closed in contact with the food.

Accordingly, an object of the present invention is a lid for a closed container with a gas discharge mechanism that can be discharged after removing the odor component contained in the gas even if the food having a specific smell, such as fermented food or fish is stored in the container and this It is providing the sealed container provided.

Still another object of the present invention is to provide a lid for a sealed container and a sealed container having the same, in which the possibility of closing the intake hole disposed on the container side by the stored food is significantly reduced.

The lid for a sealed container according to the present invention relates to a lid for a sealed container having a gas discharge mechanism that is automatically opened and closed by the elastic force of the spring to periodically discharge the gas generated in the food in the sealed container, The upper surface is opened on the lid, and a valve seat is formed on the lower surface, and a part of the valve seat is provided with a cylindrical chamber formed with a through air intake hole, and the gas exhaust mechanism is opened on the lower surface and penetrates a part of the upper surface.

The present invention relates to a lid 10 for a closed container having a gas discharge mechanism 110 that is automatically opened and closed by the elastic force of the spring 130 to periodically discharge the gas generated in the food in the sealed container 20. That is, the lid 10 for the closed container of the present invention is composed of a large chamber 100 is formed integrally with the container lid 10 and the gas discharge mechanism 110 tightly fixed in the chamber 100.

Referring first to the chamber 100, in the embodiment of the present invention, the chamber 100 is integrally formed on the container lid 10, which is the container 100 by injection molding the synthetic resin material chamber 100 This is because it is easy to form a batch at a time. However, the present invention does not exclude the coupling of the chamber 100, which is made separately, to the container lid 10. As shown in Figure 3, the chamber 100 has a cylindrical shape as a whole, the upper surface of the chamber 100 is open so that the gas discharge mechanism 110 to be described later can be inserted and fixed, the lower surface of the gas The valve seat 102 is formed on which the open /

close valves

140 and 140 ′ of the discharge mechanism 110 can be seated while maintaining airtightness. In addition, a portion of the valve seat 102 has a through hole intake 104 is formed, the intake hole 104 serves as a passage for discharging the gas generated in the food contained in the sealed container 20.

The gas discharge mechanism 110 inserted into and fixed to the chamber 100 is an important component that functions as a valve mechanism that is periodically opened and closed according to the pressure of the gas generated inside the vessel 20. The gas exhaust mechanism 110 includes a cylindrical housing 112, a deodorizing filter 120, a spring 130, and an opening /

closing valve

140 and 140 ′ disposed in the housing 112.

2 and 3, in the embodiment of the present invention, the housing 112 has a cylindrical shape, the lower surface of which is opened and a portion of the upper surface of which the through-hole exhaust hole 114 is formed. The exhaust hole 114 forms a passage for discharging the gas in the container 20 together with the intake hole 104 of the chamber 100 described above. In addition, the upper surface of the housing 112 tightly fixed to the inside of the chamber 100 is preferably on the same plane as the upper surface of the container lid 10, which is not only aesthetics of the sealed container but also a sealed container loaded in multiple stages. This is to make it easy to do. After the housing 112 is mounted in the chamber 100, it must be mutually coupled to maintain airtightness except for the exhaust hole 114. This coupling method may be used in a variety of known means. For example, coupling methods such as interference fitting, gluing, fusion, and screwing may be utilized.

In addition, a space is formed inside the housing 112, and a deodorizing filter 120 is disposed at the top of the inner space. The deodorizing filter 120 is provided to prevent the odor generated from the food contained in the container 20, in particular, the fermentation odor peculiar to the fermented foods with the gas out of the gas discharge mechanism (110). The deodorizing filter 120 is preferably a porous material having a property that the gas generated in the container 20 can pass while absorbing the odor. In the embodiment of the present invention, the deodorizing filter 120 is preferably made of at least one material selected from the group consisting of activated carbon, porous ceramics, porous silicon, hollow fiber membranes, silver coated activated carbon.

One end of the spring 130 is in close contact with the lower surface of the deodorizing filter 120, and the on / off

valves

140 and 140 which are in close contact with the valve seat 102 of the chamber 100 are maintained below the spring 130. ') Is placed. The on-off valves 140 and 140 'are elastically supported by the springs 130, and thus the on-off valves 140 and 140' are different in size between the elastic force of the spring 130 and the pressure of the gas generated inside the container 20. It is opened and closed accordingly. That is, as shown in FIG. 4, when the elastic force of the spring 130 is sufficiently larger than the pressure of the gas, the gas in the container 20 is maintained because the on / off

valves

140 and 140 ′ are in close contact with the valve seat 102 to maintain airtightness. Of course, food, in particular, liquid food does not flow out of the container (20). FIG. 5 illustrates a case where the pressure of the gas generated by the food in the container 20 is large enough to withstand the elastic force of the spring 130. As shown in the drawing, the on / off valves 140 and 140 'are raised by the pressure of the gas. Is separated from the valve seat 102, the intake hole 104 of the chamber 100, the inner space of the chamber 100, the deodorizing filter 120 made of a porous material, and the exhaust hole of the housing 112 A passage along 114 is completed such that the gas inside the vessel 20 is vented out. At this time, the deodorizing filter 120 removes the odor component contained in the discharged gas, and when the pressure of the gas falls below the elastic force of the spring 130 through the discharge process, the on-off valves 140 and 140 'again the valve seat 102 ) To maintain confidentiality. The operation of the on-off valves 140 and 140 'is automatically repeated.

Meanwhile, a spring mounting groove 122 through which the spring 130 may be seated may be formed along the bottom edge of the deodorizing filter 120, which reduces the left and right flow of the spring 130 to the on / off

valves

140 and 140 ′. This is to provide a more uniform elastic force.

In one embodiment of the present invention shown in Figures 1 to 5, the on-off valve (140,140 ') consists of a spherical ball (140), whereby the valve seat 102 is the ball 140 It is formed into a spherical surface corresponding to the curvature of.

A locking jaw 116 having an inner diameter smaller than the outer diameter of the ball 140 is formed at the bottom of the housing 112, and the ball 140 is separated from the housing 112 by the locking jaw 116. It is not possible to maintain the state accommodated inside the housing 112. At this time, the side of the cylindrical housing 112 is preferably formed at least one or more incision groove 118 along the longitudinal direction, the side of the housing 112 divided into several pieces by the incision groove 118 is This is because it can be elastically open to push the deodorizing filter 120, the spring 130 and the ball 140 into the housing 112.

As such, when the locking jaw 116 is formed at the bottom of the housing 112 to form one assembly such that the deodorizing filter 120, the spring 130, and the ball 140 are not separated, the chamber of the container lid 10 is formed. The operation of fixing the gas discharge mechanism 110 to 100 has an advantage of being easier.

Figure 6 shows another embodiment of the present invention, the basic configuration or operation principle is the same as the embodiment of the present invention shown in Figures 1 to 5, but the on-off valves 140, 140 'of the spring 130 There is a difference in that it consists of a stem 142 inserted inwardly and a hemispherical valve 140 'connected to the stem 142. The shape of the valve has an advantage that it is possible to more surely ensure the airtightness of the container 20 than the valve of the ball 140 shape. That is, in the present invention, the container lid 10, the housing 112, and the opening / closing valves 140 and 140 'are considered to be made by injection molding a synthetic resin material. In the case of injection molding a spherical ball 140, the part where the mold meets Due to the characteristics of the ball 140 that the parting line (Parting Line) that can be rotated randomly in the valve seat surface 102 in consideration of the drawback that the adhesion to the valve seat surface 102 may be inhibited. The hemispherical valve 140 ′ of the embodiment shown in FIG. 6 does not have to be rotated, and thus, this problem can be solved by making the parting line on the hemispherical side of the hemispherical valve 140 ′ (cutting side of the hemisphere). In addition, it is also an advantage of the hemispherical valve 140 'that the stepped portion 144 on which the spring 130 is seated may be formed at the connection portion between the hemisphere and the stem 142. The step 144 minimizes the flow of the spring 130 together with the spring mounting groove 122 of the deodorizing filter 120 so that the elastic force of the spring 130 is more uniformly transmitted to the hemispherical valve 140 '. In this embodiment, the valve seat 102 has the same spherical surface corresponding to the curvature of the hemispherical valve 140 ', and the locking step having an inner diameter smaller than the outer diameter of the hemispherical valve 140' at the bottom of the housing 112. The same is true for forming 116 and forming at least one cutaway groove 118 along the longitudinal direction of the cylindrical housing 112.

Meanwhile, in the embodiment of the present invention, the chamber 100 is made to protrude from the lower surface of the container lid 10 as shown in FIGS. 2 to 6, and the intake hole 104 protrudes from the cylindrical chamber 100. It is advantageous to form on the side of the. This is because if the intake hole 104 is disposed on the bottom surface of the chamber 100, the food in the container 20 contacts the bottom surface of the chamber 100 to avoid the risk that the intake hole 104 may be closed by the food. It is for. Although the number of the intake holes 104 formed on the side of the chamber 100 is sufficient, it is preferable to form a plurality of intake holes 104 to have a higher probability of preventing the intake holes 104 from being completely closed. Furthermore, it is more preferable to form the plurality of intake holes 104 at equal intervals.

The lid 10 for the sealed container of the present invention as described above, as shown in Figure 1, to form a completed closed container with the container 20 coupled thereto. The inside of the container 20 to maintain airtightness by the lid 10 for the airtight container forms a sealed receiving space, and various foods are stored in the receiving space.

The sealed container according to the present invention, as shown in Figure 7, in the actual use may be a plurality of sealed containers can be stacked up and down. Here, a leg 200 is formed at the bottom edge of the container 20, and when a plurality of airtight containers are loaded up and down, a space portion is formed between the bottom of the upper airtight container and the top of the bottom airtight container. . This is to prevent the flow of the gas discharged through the gas discharge mechanism 110 provided in the bottom sealed container is not disturbed. In particular, the leg 200 is formed discontinuously so that the space formed between the lower surface of the upper container and the upper surface of the lower container is preferably configured to communicate freely with the outside air.

While the invention has been shown and described in connection with specific embodiments, it will be appreciated that various modifications and variations can be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone can grow up easily.
