The present invention relates to a lid of a vacuum container provided with a check valve, and more particularly, a check valve is composed of a single part, and the assembling property is improved by facilitating assembly by vacuum-mounting the packing under the lid. It is a multi-purpose vacuum container lid that is convenient for use because the product price is lowered and the price competitiveness is increased while pressing the lid to close the packing to the container body and the internal air is released through the check valve to evacuate the inside of the container.

In general, food is relatively easily deteriorated, and therefore, in order to store food for a long time, a separate means for preventing deterioration is required. As such a food storage means for preventing food deterioration and long-term storage are known methods using a refrigeration technique and a method using a vacuum.

Generally, food or cooked food is packaged in wraps or plastic paper and stored in a freezer such as a refrigerator. However, the method using the refrigeration technology requires a separate refrigeration machine and power, there is a problem of rising costs, and the refrigeration technology has a limit in preventing contact between food and air, so the long-term storage of food was not effective. . That is, the storage form of the freezer can be stored for a predetermined period of time, but in the long term there is a problem that can not be stored for a long time due to the oxidation and decay of food and food due to the air contained in the packaging.

On the other hand, the conventional food container is a structure in which the food is simply put in a storage container and only the lid is closed, and the food in the container is easily deteriorated and deteriorated by bacterial propagation, which makes it difficult to store for a long time.

In order to solve these problems, a container for evacuating the inside by compressing air by attaching an annular packing to the edge of the container body which is in contact with the lid has been developed. However, such a container has a very small degree of vacuuming inside the container, and merely provides a function of preventing the contents stored in the container from coming into contact with outside air as a closed container. Because of this, there is a limit in storing the contents, and because of the inability to store for a long time, it was a reality that there is little reliability and satisfaction in using the food container. Furthermore, such a container has a defect that it is not easy to open the lid once the lid is closed and the user has a great effort to open the lid, which is very inconvenient to use. In extreme cases, a large force is applied to the lid to open the lid. The user often inadvertently injures the lid.In this way, excessive force is applied to the lid to open it, even if the container is shocked or shaken to open it. The food inside the container was distracted or even popped out of the container, which did not provide the user with satisfactory functions and effects. In addition, the annular packing is mounted on the container body and the lid to maintain the airtightness, the packing mounting portion is a form in which the mounting groove and the locking jaw is connected to the neighboring packing is inserted into the mounting groove through the locking jaw and the locking jaw There was a structure that prevented the escape from being caught. Therefore, it is very difficult to mold the mounting part on which the packing is mounted, and once the packing is mounted, it is not easily separated, so that cleaning of foreign substances caught between the packing and the mounting part is inconvenient.

Thus, a container having a higher degree of vacuuming and a more convenient use has been developed. In other words, since food can be stored for a long time in a vacuum state, a vacuum container has recently been developed and commercially equipped with a vacuum means for easily evacuating the inside of a container to store food in a vacuum state. Such a vacuum vessel is provided with a valve for extracting air in the lid, a representative example is the "vacuum vessel" described in Utility Model Publication No. 1998-0009712 filed by Kim Hyun-min dated June 6, 1998. The vacuum vessel is formed on the lid to form a first groove in which the first vent hole is perforated so as to communicate with the atmosphere, and a separation protrusion is formed in the upper surface thereof so that the suction pad is positioned on the first groove to open and close the first vent hole. And a vacuum release button having a pull hole that is engaged with the separation protrusion to pull the separation protrusion, and has a complicated configuration in which an elastic member is positioned between the vacuum release button and the suction pad. As such, since the conventional vacuum container is composed of a complex structure in which various parts are assembled or associated with each other, manufacturing and assembly are cumbersome, resulting in poor assembly productivity. In addition, since the valve structure is composed of many parts, the production cost of the vacuum container is high, and thus the price competitiveness is lowered. In addition, since there is no device for checking whether the container is in a vacuum state, it is inconvenient to confirm whether the vacuum is present.

Accordingly, it is an object of the present invention to provide a multi-purpose vacuum container lid which has been devised to solve the above-mentioned drawbacks and which simplifies the valve structure provided on the lid.

It is another object of the present invention to provide a versatile vacuum container lid which improves assembly performance by lowering the unit cost by forming a check valve into a single part and vacuum-packing the packing below the lid.

Another object of the present invention is to provide a versatile vacuum container lid that is convenient to use because the user presses the lid and the packing is in close contact with the container body to form a vacuum through the check valve.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an assembled perspective view showing an embodiment of a vacuum container with a multi-purpose vacuum container lid according to the present invention, Figure 2 is an exploded perspective view of FIG. 3 is a cross-sectional view taken along the line A-A of FIG. This embodiment illustrates a vacuum container in the form of a substantially square barrel, the shape of the vacuum vessel can be implemented in the form of a polygonal cylinder, such as a triangular cylinder, a hexagonal cylinder, an octagonal cylinder or a cylinder in addition to the square cylinder shape illustrated in this embodiment. The present invention is not limited by the form.

The lid of the vacuum container is a lid body (20) for opening and closing the inlet and the lid is attached to the opening inlet 12 of the container body 10, which provides a space for containing the contents, such as food, as shown It is provided with a check valve 30 and the packing 40 mounted on the body 20 to control the inflow and outflow of air.

The container body 10 is preferably in the form of a rectangular cylinder whose cross-sectional area gradually increases from the bottom to the top, and is made of a solid material that can withstand vacuum pressure. The material of the container body 10 is preferably a plastic series having good pressure resistance.

The lid body 20 is provided with a valve seating groove 22 in the center portion thereof, and a coupling hole 22-1 for coupling the check valve 30 to the center of the valve seating groove 22 is provided. Formed. The valve seating groove 22 is preferably recessed in a circular shape with an area capable of accommodating the check valve 30, and the coupling hole 22-1 protrudes from the bottom of the valve seating groove 22 to a certain height. It is perforated at the center of one central projection portion 22-2. The central protrusion 22-2 floats and supports the check valve 30 at a predetermined height from the bottom surface of the valve seating groove 22. Accordingly, the check valve 30 is moved up and down according to the operating pressure. Elastic movement can be performed easily. In the central protrusion 22-2, an air contact hole 24 is formed on the side thereof, and when the lid is closed, the air inside the container 1 is discharged to the outside to make the container 1 vacuum, and when the lid is opened. Into the outside air is introduced to release the vacuum in the container (1). This part will be described in more detail in the operation description of the lid of the vacuum container. As shown in FIG. 2, the air contact hole 24 rotates along the side of the central protrusion 22-2, and is formed in a substantially straight shape. The air contact hole 24 is formed in a similar manner to a human inlet tank so that a distinctive sound of air leaking out when the air flows in and out is formed. Cause it to occur.

The lid body 20 is shaped into a spherical shape from the valve seating groove 22 toward the outside, and in particular, the spherical part 26 is convex in the center side adjacent to the valve seating groove 22 as compared with the outer side. Is shaped into a protruding shape. As such, the lid body 20 has a spherical shape and has excellent pressure resistance that can withstand high vacuum inside the container. The outer edge 28 of this spherical portion 26 is formed to extend. The rim 28 of the lid body 20 is bent in the form of a wing downward to cover a portion of the inlet 12 of the container body 10 when viewed in cross section as shown in the cross-sectional view of FIG. In particular, the inside of the rim 28 of the lid body 20 is fitted with a packing (packing; 40) for keeping in close contact with the inner surface of the inlet portion 12 of the container body 10 when closed.

Since the packing 40 has a container 1 in the shape of a square cylinder, the packing 40 has a shape corresponding to the inlet portion 12 of the container body 10 in close contact therewith, that is, a square band or a square ring shape. The packing 40 has an inner vertical mounting portion 42 and a close contact portion 44 which is bent outwardly from the mounting portion 42 and extends in a substantially horizontal direction to be in close contact with an inner surface of the inlet portion 12 of the container body 10. Consists of The close contact portion 44 is made thinner toward the end to improve elasticity and flexibility, so as to be in close contact with the inner surface of the container body 10. Furthermore, the elastic protrusion 44-1 protrudes upward in the vicinity of the end portion of the close contact portion 44 and is compressed by the lid body 20 which is lowered when the lid is closed. When the operating force is removed, the lid is slightly restored while raising the lowered lid to expand the air inside the container, contributing to vacuuming the inside of the container. The elastic protrusion 44-1 is formed in the contact portion 44 in a conical or horn shape at regular intervals, preferably at least one of each side of the rectangular band-shaped packing 40 is good, in addition to this The packing 40 may be formed by being connected in a band shape while circumscribing. In order for the elastic protrusion 44-1 to operate more smoothly, a flat contact surface 28-2 is provided on the inner surface of the lid body 20 corresponding to the elastic protrusion 44-1 so that the elastic protrusion 44-1 is in contact with the elastic protrusion 44-1. On the other hand, the end of the mounting portion 42 of the packing 40 is formed with a press-fit projection 42-1 in the form of a hook. The hook-shaped indentation protrusion 42-1 increases the degree of vacuum by increasing the elastic force when inserted into the packing mounting groove 28-1 to improve the adhesion. In this way, the packing 40 is provided with a packing mounting groove 28-1 inside the rim 28 of the lid body 20 to be combined and mounted. The packing mounting groove 28-1 is opened in the downward direction as shown in FIG. 3, so that the packing mounting groove 28-1 is easily mounted by pushing the mounting portion 42 of the packing 40 upwards from the bottom. At this time, when the mounting portion 42 of the packing 40 enters the packing mounting groove 28-1 and is completely inserted, the air of the packing mounting groove 28-1 is in close contact with the inner surface of the packing mounting groove 28-1. As it exits completely and becomes a vacuum, the pressure maintains a firm bond. By this vacuum mounting, when the pressure to be separated from the packing mounting groove 28-1 acts uniformly on the packing 40, the packing 40 does not easily come out of the packing mounting groove 28-1. After releasing the vacuum by pulling a part of the packing 40 by hand, the packing 40 may be easily separated by gradually separating the packing 40 from the packing mounting groove 28-1. Therefore, in the normal operation of closing or opening the lid to the container body 10, uniform pressure is applied between all the parts of the packing 40, and the separation does not occur, and the user needs to separate the packing as in the case of cleaning. In this case, by pulling a portion of the packing 40 by hand and applying pressure to one point, the packing 40 can be easily removed from the packing mounting groove 28-1 and then cleaned. Since this is the same as the principle of the adsorption board, it will be easily understood considering the attachment and removal of the adsorption board.

The check valve 30 described above has a shape similar to an umbrella, and a coupling protrusion 34 is inserted into and engaged in the coupling hole 22-1 of the lid body 20 at the center of the hemispherical body portion 32. have. An inclined locking jaw 34-1 protrudes in the circumferential direction at the lower end of the engaging projection 34, and its taper is tapered so that the diameter becomes smaller toward the lower end in the longitudinal direction (insertion direction). It is supposed to be done. The check valve 30 is made of an elastic material, preferably made of silicon, rubber, or the like, and more preferably silicon having no discoloration or corrosion due to outside air is suitable. As such, the check valve 30 is manufactured using a material having good adhesion, so that the edge of the body portion 32 faces the air in the state where the hemispherical body portion 32 surrounds the air contact hole 24 ( It adheres to the surface of 20) to block the inflow of air. In this way, the body portion 32 of the check valve 30 surrounds the air contact hole 24, the air discharged through the air contact hole 24 is the body portion 32 in close contact with the lid body 20 It is discharged while floating the edge of). More specifically, by the structure of the check valve 30, the air inside the container is pushed to the body portion 32, one side edge of the body portion 32 that is in close contact with the lid body 20, the gap is heard Although it is discharged, the pressing force acting on the body portion 32 by the outside air acts toward the lid body 20 so that the body portion 32 is in close contact with the lid 20 to block the inflow of outside air. In this way, the check valve 30 permits air flow in only one direction (discharge direction of the internal air) and blocks air flow (inflow of outside air) in the opposite direction. Therefore, in order to separate the lid from the closed vacuum container, the check valve 30 is opened by the user by slightly lifting the outside air into the container by releasing the vacuum pressure of the lid.

In particular, the check valve 30 has a hemispherical body portion 32 with a low vacuum display portion 36a and a high vacuum display portion 36b. The low vacuum display portion 36a is formed to protrude in a small hemispherical shape from the surface of the body portion 32, and when the lid is closed to form a vacuum in the container body 10, the protruding hemispherical portion 36a-1 is inside. As it is sucked into and deformed into a recessed state, the container user can easily report whether the inside of the container is low vacuum. Of course, when the vacuum is released into the container, the sucked hemispherical portion 36a-1 of the low vacuum display portion 36a protrudes and returns to its original state. On the other hand, the high vacuum display portion 36b is in the form of a column shape of the inside and the top surface is closed in a hemispherical shape, preferably when high vacuum is formed inside the sealed container protruding in a cylindrical shape of a smaller diameter than the low vacuum display portion 36a The hemispherical part 36b-1 of the upper surface is kept sucked inside. Of course, when the vacuum is released inside the container, the sucked hemispherical portion 36b-1 of the high vacuum display unit 36b protrudes to its original state and returns to the original state. The high vacuum display portion 36b having such a function is manufactured by forming the cylindrical side wall 36b-2 thickly to a certain degree so that the user can lift the check valve 30 when the external air is forced into the container. Can serve as a handle. On the other hand, in the case of a container having a low vacuum is sufficient and there is no need for a high vacuum, the interior of the high vacuum display portion 36b can be completely filled and used only as a handle. The body portion 32 of the check valve 30 is also provided with a date indicator 38 indicating the storage date. The date indicator 38 is configured by protruding the surface of the body portion 32 in a triangular shape, in addition to protruding or displayed with an arrow or a point, it is sufficient if the user can confirm. The date indicator 38 has a check valve 30 is rotated about the coupling protrusion 34 as the axis of the lid body 20 of the periphery of the check valve 30 in the annular shape of the date display portion 29 It will indicate the date. In this way, the user rotates the check valve 30 so that the date indicator 38 indicates the storage date of the date display unit 29 so that the amount of food stored in the container 1 can be easily checked.

On the other hand, it is preferable to form handles (not shown) on at least one side of the container body 10 or the lid on both sides of the surface thereof, so that the user can comfortably hold the vacuum container 1.

4 and 5 are views for explaining the operation of the vacuum chamber lid when closing the vacuum chamber, in particular Figure 4 is a state in which the lid on the container body and Figure 5 in the state of Figure 4 to press the container The vacuum sealed state is shown by the cross-sectional view, respectively.

When the user presses the lid body 20 downward while covering the lid at the inlet portion 12 of the container body 10 while the contents, for example, food (not shown), are placed inside the container body 10. As in the close contact portion 44 of the packing 40 is in contact with the inlet portion 12 of the container body 10 and the outer end is bent in a state of upward facing the lid is lowered air in the container body 10 It is discharged through the air contact hole (24). At this time, while the air is discharged through the air contact hole 24, the sound coming out of the air. The user can hear this sound and confirm as a sound whether the vacuum operation is performed. The air discharged through the air contact hole 24 is discharged from the container 1 by lifting the check valve 30 which is in close contact with the upper surface of the lid body 20, and the lowered lid when the user's pressing force is removed. The silver is slightly risen by the elastic restoring force of the packing 40 to expand the air in the container to vacuum the inside of the container. At this time, the packing 40 is bent in close contact with the inner surface of the inlet portion 12 of the container body 10, as shown in Figure 5 to close the inlet of the container body 10 completely, the check valve The hemispherical portion 36a-1 of the low vacuum display portion 36a of 30 is recessed to display the container 1 so that the user can confirm that the container 1 is in a low vacuum state.

6 is a view showing the operation of opening the lid of the vacuum vessel, with reference to this figure will be described in detail the operation of opening the lid of the vacuum-sealed vacuum vessel described above.

In order to use the food by opening the vacuum-packed vacuum container as shown in FIG. 5, as shown in FIG. 6, when the user grabs and lifts the high vacuum display unit 36b serving as a handle, the check valve 30 is lifted. Outside air is introduced into the gap while one side is in close contact with the surface of the lid body 20 is introduced into the container body 10 through the air contact hole 24 of the lid body 20 to the inside of the container (1) The vacuum is released. Accordingly, the packing 40 mounted on the rim 28 of the lid body 20 is separated from the inlet 12 of the container body 10 while the lid is lifted from the container body 10. At the same time, the hemispherical part 36a-1 of the low vacuum display part 36a of the check valve 30 protrudes in the recessed state, and returns to the original projected position. When the user lifts the lid in this state, the lid is separated from the container body 10 lightly.

7 and 8 are views showing the packing mounting method in the lid of the vacuum container, Figure 7 is a state before mounting the packing in the packing mounting groove, and Figure 8 is a state in which the packing is attached to the packing mounting groove combined. .

As shown in FIG. 7, facing the mounting portion 42 of the packing 40 in the packing mounting groove 28-1 provided inside the rim 28 of the lid body 20, and pushing in the arrow X direction, the packing mounting groove ( As the air in the 28-1) is pushed out, the silicon packing 40 is elastic and is inserted into the packing mounting groove 28-1. At this time, the hook-shaped indentation protrusion (42-1) is inserted into the packing mounting groove (28-1) to improve the adhesion with the inner wall of the lid body 20 forming the packing mounting groove (28-1) while elastically deformed Increase the vacuum mounting force. As a result, as shown in FIG. 8, the inner wall of the lid body 20 constituting the mounting portion 42 of the packing 40 and the packing mounting groove 28-1 in contact therewith is closely adhered and coupled in a vacuum state. Even if the locking step does not exist in the separation direction, a firm coupling force is obtained that is not easily separated. This is also the same as the principle of the adsorption board, so that when a large pressure acts at a uniform pressure across all the bands of the rectangular band-shaped packing 40, it is not separated, and when cleaning, the user floats a point first so that air is introduced therefrom. It can be easily removed if it is gradually released.

FIG. 9 is a perspective view showing a state in which a part of the vacuum container cap is used to explain the state of use of the check valve as the date display, and FIG. 10 is a plan view of FIG.

As shown, the check valve 30 is rotatable about its coupling protrusion (not shown) in the valve seating groove 22 provided in the lid body 20 and adjacent to the check valve 30. On the surface of the lid body 20, a date display unit 29 is provided while enclosing the check valve 30. Accordingly, the user can specify the storage date by rotating the check valve 30 so that the date indicator 38 indicates the corresponding date of the date display unit 29 displayed on the lid body 20. For example, if it is the second day that the food is stored in the vacuum container today, the check valve 30 is rotated so that the date indicator 38 indicates 2 of the date display unit 29 displayed on the lid body 20. By letting it know that it is the second day, it can be displayed so that it is easy to confirm that the storage date is the third day by turning the date indicator 38 of the check valve 30 to three characters tomorrow.
