BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage container, and more particularly, to a storage container that can easily couple and separate a cover to a container body.

In recent years, storage containers have been widely used for storing food and for hygienic storage. 1, the conventional storage container 10 is composed of a cover 12 and a container body 16, and a coupling vane 14 is provided around the cover 12, and the container body 16 A hooking step 18 is formed around which the four coupling vanes 14 are hooked. In order to fully engage the container body 16 by engaging the cover 12 to the container body 16, all four engagement vanes 14 must be pulled downward to catch on the latching step 18. In order to separate the cover 12 from the container body 16, all four coupling blades 14 must be pulled up and separated from the latching step 18.

As described above, in the conventional storage container 10, since the coupling vanes 14 must be pulled down or pulled up in the process of coupling and separating the cover 12, there is a problem that it is inconvenient to use. Particularly, when one coupling wing 14 among the four coupling wings 14 is not locked in the process of separating or coupling the cover 12, the contents inside the container body 16 may flow out to the outside, 16), and the contents are damaged.

In the conventional storage container 10, the connecting portion of the cover 12 and the coupling vane 14 is formed concavely for smooth rotation of the coupling vane 14. However, there is a problem that the cover 12 is not cleanly cleaned due to the connection portion of the cover 12 and the coupling vane 14 concavely formed in this manner. In particular, the conventional storage container 10 has a problem that all four coupling vanes 14 have to be cleaned.

In addition, the conventional storage container 10 has a rubber packing 15 inserted into the cover 12. The rubber packing 15 serves to seal between the cover 12 and the container body 16 when they are engaged with the container body 16. However, the conventional storage container 10 has a problem that the packing 15 is deformed or contracted due to repetitive engagement of the cover 12, whereby the sealing force is lowered.

FIG. 2 is a perspective view illustrating a combined state of the storage container 100 according to an embodiment of the present invention, and FIG. 3 is an exploded perspective view of the storage container 100 illustrated in FIG.

Although the storage container 100 according to the present embodiment is illustrated as having a square shape with a curved edge, it may have various shapes such as a polygonal shape, an elliptical shape, or a circular shape.

Referring to FIG. 2, the storage container 100 according to the present embodiment includes a cover 120, a container body 200, and a packing 260. The cover 120 has a rotating member 140 for engaging the container body 200 around the cover 120. The storage container 100 according to the present embodiment can easily couple and separate the cover 120 to the container body 200 by operating one rotary member 140. [

A packing 260 is coupled to the cover 120. When the cover 120 is coupled to the container body 200, the packing 260 is interposed between the cover 120 and the container body 200 to provide a sealing force.

Hereinafter, the cover 120 of the storage container 100 according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4. FIG.

4 is a perspective view illustrating the bottom surface of the cover 120 of the storage container 100 illustrated in FIG.

2 to 4, the cover 120 is coupled to the container body 200 to close the container body 200. One rotating member 140 is rotatably coupled to the side surface of the cover 120. The cover 120 is engaged with the container body 200 while moving downward in the process of engaging the rotation member 140 to the rotation engaging portion 220 of the container body 200.

The cover 120 includes a cover body 122, an outer circumferential surface 124, a rear protrusion 130, side protrusions 160, an inner circumferential surface 170, and a packing groove 180. A rotary member 140 is rotatably coupled to one side of the outer circumferential surface 124 of the cover 120.

Since the cover body 122 covers the upper portion of the container body 200, the cover body 122 has a cross-section similar to that of the container body 200. Since the cover body 122 moves in the horizontal direction while being lifted up on the container body 200, the cover body 122 is formed to be slightly larger than the opening of the container body 200. An outer circumferential surface 124 is formed around the cover body 122 and an inner circumferential surface 170 and a packing groove 180 are formed inside the cover body 122.

The outer circumferential surface 124 forms an outer surface of the cover 120 and is formed to extend downward with a predetermined length from the cover body 122. In the cover body 122 having a rectangular shape, the outer circumferential surface 124 is formed on the three side surfaces thereof and the outer circumferential surface 124 is formed on the other side surface (the portion where the circumferential grooves 126 are formed) Or is formed to have a short length even if it is formed. A rotary member 140 is coupled to a portion where the outer circumferential surface 124 is not formed or whose length is short.

The cover 120 according to the present embodiment has a structure in which the outer circumferential surface 124 has a certain length on three sides and extends downward. Therefore, even if the inner surface of the cover 120 is directed to the bottom, the inner circumferential surface 170 and the packing 260 inside the cover 120 do not contact the bottom. Thus, even if the cover 120 is not turned upside down, it is possible to solve the problem that the bottom surface is contaminated by the cover 120 or the inner surface of the cover 120 is contaminated by the bottom surface.

2 to 3, the outer circumferential surface 124 has a curved section in cross section. The packing 260 located inside the outer circumferential surface 124 has a higher inner circumferential edge 266 than the outer circumferential surface 264 corresponding to the shape of the outer circumferential surface 124.

A greater elastic force is applied to the inner rim 266 when the cover 120 is engaged with the container body 200 because the inner rim 266 is formed higher than the outer rim 264. In addition, when the cover 120 is disengaged from the container body 200, the cover 120 can be easily moved in the upper direction by the resilient restoring force of the inner rim 266.

The outer circumferential surface 124 is inclined outward so that the cover 120 can be easily moved laterally when the cover 120 is engaged with the container body 200. That is, when the cover 120 is engaged with the container body 200, the inner surface of the outer circumferential surface 124 presses the container end portion 212 of the container body 200 downward while the outer circumferential surface 124 The side surface of the cover 120 is more easily moved.

Since the outer circumferential surface 124 is located on the outer side of the base end portion 212 of the container body 200, even if the storage container 100 is impacted by dropping or the like, Thereby preventing the cover 120 from being opened.

A circumferential groove 126 is formed on one side of the outer circumferential surface 124. The peripheral groove 126 corresponds to a portion formed slightly concave on the outer peripheral surface 124. The circumferential groove 126 is formed with a concave pressing surface 128. An air passage 129 corresponding to a passage through which air can flow into the container body 200 is formed inside the pressing surface 128.

The pressing surface 128 corresponds to a portion formed thinner than other portions of the peripheral groove 126. When the cover 120 is engaged with the container body 200, the pressing surface 128 is pressed by the pressing protrusion 148 and is laterally deformed to press the packing 260. As a result, the air passage 129 formed inside the pressing surface 128 is sealed by the packing 260.

At the portion where the peripheral groove 126 is formed, the rotary member 140 rotatably engages with the outer peripheral surface 124 as shown in FIG. The peripheral groove 126 provides a space in which the pressing projection 148 formed on the rotary member 140 can rotate.

A pair of rear protrusions 130 protrude from the inside of the outer circumferential surface 124. The rear protrusions 130 are formed at positions opposed to the peripheral grooves 126 in the outer circumferential surface 124. The rear protrusion 130 is caught by the rotation latching portion 220 formed on the container body 200.

The rear protrusions 130 may have inclined surfaces (not shown). The inclined surface allows the rear projection 130 to be easily engaged with the rotation stopper 222 of the rotation stopper 220.

Although the cover 120 according to the present embodiment is illustrated as having a pair of rear protrusions 130, one or more of them may be provided. Although the rear protrusions 130 are illustrated as being coupled to the lower portion of the container frame 210 of the container body 200, they may be coupled to the container frame 210 at the same height or may be coupled thereto. That is, the storage container according to the present invention is not limited by the height of the rear projection.

On the inner side of the outer circumferential surface 124, a pair of side projections 160 are formed symmetrically. The side projections 160 are caught by the side catches 230 formed on the container body 200. [

A side surface and / or an upper surface of the side surface protrusion 160 may be formed with an inclined surface (not shown). The inclined surface allows the side projection 160 to be easily engaged with the side engagement portion 230.

The cover 120 according to the present embodiment is illustrated as having four side projections 160 on both sides. However, this is an exemplary one, and the cover 120 may have one or more side projections on each of the left and right sides.

Although the side projection 160 is illustrated as being hung below the container frame 210 of the container body 200, the side projection 160 may be coupled to the container frame 210 at the same height or may be provided with a separate projection . That is, the storage container according to the present invention is not limited by the height of the side projection 160.

On the inner surface of the cover body 122, an inner circumferential surface 170 protrudes downward. The inner circumferential surface 170 is located inside the outer circumferential surface 124. Between the inner circumferential surface 170 and the outer circumferential surface 124, a packing groove 180 into which the packing 260 is inserted is formed.

The cover 120 of the storage container 100 according to the present embodiment moves in the lateral direction in the process of coupling to the container body 200. Therefore, in order to allow the lateral movement of the cover 120, the inner circumferential surface 170 is formed to be somewhat smaller than the opening of the container body 200.

When the cover 120 is coupled to the container body 200, the inner circumferential surface 170 is located inside the container body 200. On the inner circumferential surface (170), the positioning protrusions (172) are protruded downward at regular intervals. The positioning protrusion 172 serves to facilitate the positioning of the cover 120 when the cover 120 is placed on the container body 200. The positioning protrusion 172 also functions to prevent excessive movement of the cover 120 while contacting the inner surface of the container body 200 when the cover 120 is moved in the lateral direction.

4 to 5, an air passage 174 is formed on the inner surface of the inner circumferential surface 170 adjacent to the circumferential groove 126. The air passage 174 is located inside the container body 200 when the cover 120 is coupled to the container body 200. The air passage 174 communicates with the other air passage 129, 173. When the air passage 129 located at the outermost position is opened by the rotation of the rotary member 140, the air flows into the interior of the container body 200 through the other air passageways 173 and 174. As a result, when the cover 120 is separated from the container body 200, the open air passages 129, 173, and 174 release the vacuum pressure so that the cover 120 can be easily separated.

The packing 260 is inserted into the packing groove 180. An air passage (173) is formed in the bottom surface of the packing groove (180). The bottom surface of the packing groove 180 is formed downwardly sloping outwardly by an outer circumferential surface 124 having a curved shape, as illustrated in FIG. 10 and the like. Corresponding to the shape of the packing groove 180, the inner rim 266 of the packing 260 is formed to be higher than the outer rim 264.

The storage container 100 according to the present embodiment is exemplified as having the air passages 129, 173 and 174 formed in the cover 120. However, the packing 260 and / Of course. When an air passage is not formed in the cover 120 and an air passage is formed in the packing 260, the air passage formed in the packing 260 when the cover 120 is coupled to the container body 200, So that the air passage can be closed.

Hereinafter, the rotating member 140 coupled to the cover 120 will be described with reference to FIGS. 2 to 3 and FIGS. 5 to 6. FIG.

FIG. 5 is a perspective view illustrating the rotating member 140 of the storage container 100 illustrated in FIG. 2, and FIG. 6 is a side view of the rotating member 140 illustrated in FIG.

Referring to FIGS. 2 to 3 and 5 to 6, the storage container 100 according to the present embodiment includes one rotating member 140. The rotatable member 140 is rotatably coupled to the outer circumferential surface 124 of the cover 120 so that the cover 120 can engage with the container body 200.

The rotating member 140 includes a cutout 141, a receiving projection 144, a rotation locking projection 146, and a pressing projection 148. [ The rotary member 140 may be formed bilaterally symmetrically with respect to the pressing projection 148.

The incision 141 is formed at the center of the upper part of the rotary member 140, and a pressing projection 148 is provided therein. At the right and left sides of the cutout 141, connection end portions 142 connected to the outer circumferential surface 124 are respectively located. The rotating member 140 rotates around the connecting end 142.

The pedestal protrusions 144 protrude symmetrically on the left and right sides of the press protrusions 148, respectively. The support protrusion 144 presses the container rim 210 of the container main body 200 when the rotation member 140 rotates and engages with the rotation securing portion 220 of the container main body 200. When the rotary member 140 is further pulled downward, the rotary member 140 rotates around the support projection 144 and pulls the cover 120 in the lateral direction.

Although the storage container 100 according to the present embodiment has been described in which the cover 120 is pulled in the lateral direction by the projection projections 144 in the form of protrusions, the structure in which the thickness of the portion where the projection projections 144 are formed is thick The cover 120 can be pulled laterally. The same effect as that of the support protrusion 144 can be obtained by forming the connecting end portion 142 of the rotary member 140 further inward in the direction of the outer circumferential surface 124.

On the inner surface of the rotary member 140, a pair of rotation locking protrusions 146 protrude. The rotation locking protrusion 146 has a b shape. The rotation locking protrusion 146 is engaged with the rotation locking projection 222 of the container body 200.

One of the pressing projections 148 is provided at the center of the rotary member 140. The pressing projection 148 has a b shape, and an end portion thereof is formed to be inclined. When the cover 120 is engaged with the container body 200, the pressing projection 148 presses the pressing surface 128 so that the air passages 129 and 174 are closed by the packing 260. When the cover 120 is disengaged from the container body 200, the pressing protrusion 148 releases the lateral pressure on the pressing surface 128 so that the air passageways 129 and 174 are opened. When the cover 120 is separated from the container body 200, the pressing projection 148 is engaged with the pressing projection insertion groove 224 provided in the container body 200, The cover 120 is pushed up.

The rotary member 140 of the storage container 100 according to the present embodiment is illustrated as having a pair of symmetrically formed support projections 144 and rotation locking projections 146. [ However, it goes without saying that the arrangement and the number of the support protrusions and the rotation locking protrusions may be variously changed.

Hereinafter, the packing 260 of the storage container 100 according to the present embodiment will be described with reference to FIGS. 2 to 3 and 7. FIG.

FIG. 7 is a cross-sectional view taken along the line AA of the packing illustrated in FIG. 3; FIG.

2 to 3 and 7, the packing 260 has a shape corresponding to the cover 120. As shown in FIG. When the cover 120 engages the container body 200, the packing 260 elastically deforms to provide a sealing force.

The packing 260 has an inner space 262, an outer rim 264 and an inner rim 266.

The inner space 262 of the packing 260 corresponds to an empty space formed inside the packing 260. In the inner space 262, a plurality of packing supports 274 are vertically formed at regular intervals. The packing support portion 274 serves to increase the elastic restoring force of the packing 260.

Although the packing 260 according to the present embodiment is illustrated as having a vertically formed packing support 274, the packing support 274 may be formed in a horizontal or an oblique direction.

The outer rim 264 forms the outer surface of the packing 260 and the inner rim 266 forms the inner surface of the packing 260. Corresponding to the shape of the packing groove 180, the inner rim 266 is formed higher than the outer rim 264.

Hereinafter, the container body 200 of the storage container 100 according to the present embodiment will be described with reference to Figs. 2 to 3 and Figs. 8 to 9. Fig.

FIG. 8 is a front view illustrating the container body 200 of the storage container 100 illustrated in FIG. 3, and FIG. 9 is a sectional view along the BB line of the container body 200 illustrated in FIG.

Referring to Figs. 2 to 3 and Figs. 8 to 9, the container body 200 has a certain volume and has an empty space in which the contents (not shown) can be received. The container body 200 is formed to be symmetrical in the left and right direction and up and down. Therefore, even if the rotary member 140 of the cover 120 is disposed in any direction to the right and left with respect to the container body 200 illustrated in Fig. 8, the cover 120 can be engaged.

The container body 200 has a container frame 210, a side fastening portion 230, and a rotation fastening portion 220.

The container rim 210 is formed to protrude outward along the circumference of the container body 200. The container rim 210 is formed with a rotation engaging portion 220 to which the rotary member 140 or the rear projection 130 is engaged and a side engagement portion 230 to which the side projection 160 is engaged. In addition, the container edge 210 protrudes upward from the container end portion 212.

When the cover 120 is coupled to the container body 200, the proximal end portion 212 is pressed by the packing 260. Referring to Fig. 9, the distal end portion 212 has a curved cross section. Therefore, the pressurized packing 260 is completely adhered to the container end portion 212, thereby improving the sealing force of the packing 260. [

The side latching portions 230 are formed bilaterally symmetrically on one side of the container body 200. The side catching part 230 is a part of the container frame 210 where the side surface protrusion 160 of the cover 120 is caught. The lower part of the side latching part 230 is concave so that the side lug 160 can be easily engaged. The inlet of the side latching part 230 is formed to be inclined so that the side projection 160 can be easily inserted.

One or more side catches 230 may be provided on one side of the container body 200. Further, in the case of a circular storage container, the side latching part 230 can be formed at any position of the container body.

The side latching groove 232 has a shape in which a part of the container rim 210 is cut. When the cover 120 is lifted up to the container body 200, the side projection 160 passes through the side engagement groove 232 and is located at the same height or lower height as the container frame 210. When the cover 120 is detached from the container body 200, the side projection 160 is separated from the container frame 210 through the side catching groove 232.

The moving cut-away surface 234 is formed at a lower portion of the side catching groove 232 and has a shape in which a part of the side surface of the container body 200 is slightly recessed. The movement cut-out surface 234 facilitates lateral movement of the side projection 160 located below the side latching portion 230.

The rotation latching part 220 is formed symmetrically with respect to the other side surface of the container body 200. The rotation locking protrusion 146 of the rotating member 140 is engaged with the rotation locking part 220. The rotation latching unit 220 includes a rotation latching protrusion 222 and a pressing projection insertion groove 224.

The rotation latching protrusion 222 protrudes downward from the lower surface of the container frame 210, and has a predetermined length in the horizontal direction. The rotation locking protrusion 146 or the rear protrusion 130 of the rotary member 140 is engaged with the rotation locking protrusion 222.

A pressing projection inserting groove 224 is formed on the inner side of the rotation latching protrusion 222. The pressing projection insertion groove 224 corresponds to a groove formed at a predetermined depth in the container frame 210. An end portion of the pressing projection 148 provided in the rotary member 140 is inserted into the pressing projection insertion groove 224. This can prevent the pressing projection 148 from catching on the container rim 210 and restricting the rotation of the rotary member 140. When the rotary member 140 is lifted so as to separate the cover 120 from the container body 200, the pressing projection 148 hits the pressing projection insertion groove 224 and lifts the cover 120 upward It plays a role of raising.

The pressing projection insertion groove 224 can be formed not only by the groove shape but also by the projection. Further, the pressing projection insertion grooves 224 can be arranged in various ways. For example, when the storage container 100 is circular, a plurality of pressure projection insertion grooves may be provided at regular intervals.

A hole (not shown) is formed at the center of the bottom surface of the presser projection insertion groove 224. The holes serve to discharge the foreign substances introduced into the pressing projection insertion grooves 224.

The container body 200 of the storage container 100 according to the present embodiment is illustrated as having a rotation protrusion 222 protruding downward. However, it is needless to say that not only the protrusion shape but also the groove shape can be used as the structure that can be engaged with the rotation locking protrusion 146 of the rotary member 140.

The side surface of the container body 200 may be formed slightly concave. The concave portion strengthens the strength of the container body 200. The concave portion formed on the side surface of the container body 200 secures a space between the contents (not shown) and the inner surface of the container body 200 to facilitate air circulation, Thereby facilitating the discharge of the liquid in the chamber.

Hereinafter, the process of coupling the cover 120 of the storage container 100 to the container body 200 according to the present embodiment will be described with reference to FIGS. 10 to 15. FIG.

10, 12 and 14 are views sequentially illustrating the process of coupling the cover 120 to the container body 200, and show cross-sectional views illustrating the coupling relationship between the rotation member 140 and the rotation engaging portion 220 to be. 11, 13, and 15 are views sequentially illustrating the process of attaching the cover 120 to the container body 200, respectively, and correspond to FIGS. 10, 12, and 14, And the side engaging part 230, as shown in FIG.

10 and 11 are sectional views of an initial state in which the cover 120 is coupled to the container body 200. 10, the interior of the circle is a sectional view illustrating a state in which the air passages 129, 173, and 174 are opened.

Referring to FIG. 10, the cover 120 is first placed on the container body 200 to engage the cover 120 with the container body 200. At this time, the inner circumferential surface 170 and the positioning protrusion 172 provided in the cover 120 are positioned inside the container end portion 212 to set the position of the cover 120. The abutment projection 144 of the rotary member 140 is in contact with the container frame 210. The end of the press protrusion 148 is located inside the presser projection insertion groove 224, Is not caught by the rotation stopper 222. Also, the rear protrusion 130 is not caught by the rotation locking protrusion 222.

The air passages 129, 173, and 174 are in the open state. That is, since the packing 260 is not pressed in the vertical direction, the air passage 173 formed in the packing groove 180 is not closed by the packing 260 but is opened. Since the pressing surface 128 is also not pressed in the lateral direction by the pressing projection 148, the air passages 129 and 174 are also in an open state.

Referring to FIG. 11, in the state of FIG. 10, the side projection 160 passes through the side engagement groove 232 and is located lower than the container edge 210. At this time, the side projections 160 are in a state before being caught by the side catches 220.

When the rotary member 140 is pressed downward (rotated in the clockwise direction) in the states of FIGS. 10 to 11, the cover 120 moves to the left and downward directions and enters the state of FIG. 12 to FIG.

12 to 13 are sectional views of an intermediate process in which the cover 120 is coupled to the container body 200. As shown in FIG.

10 to 11, when the rotary member 140 is pressed downward, the support protrusion 144 presses the container rim 210. 12 and 13) by moving the cover 120 in the lateral direction (the right direction in Figs. 10 and 11) while rotating about the receiving projections 144, .

By the lateral and downward movement of the cover 120, the side projections 160 are also caught by the side catches 230 while moving sideways and downwards, as illustrated in Fig.

Referring to FIG. 12, the rotation locking protrusion 146 of the rotating member 140 is in contact with the rotation locking protrusion 222 as an initial step of the coupling. Further, the rear projection 130 also contacts the rotation stopper 222 as an initial stage of the engagement.

When the rotary member 140 is further pulled downward in the states of Figs. 12 to 13, the state shown in Figs. 14 to 15 is obtained.

Figs. 14 to 15 are sectional views illustrating a state in which the cover 120 is fully engaged with the container body 200. Fig. 14 is a sectional view illustrating a state in which the air passages 129 and 173 174 are closed inside the circle.

14 to 15, when the cover 120 is completely engaged with the container body 200, the rotation locking protrusion 146 of the cover 120 is engaged with the rotation locking protrusion 222, and the cover 120 Is also engaged with the rotation latching protrusion 222. Therefore, one side (the right part in Fig. 14) and the other side (the left part in Fig. 14) of the cover 120 are all joined. In addition, the side projections 160 of the cover 120 are all caught by the side catches 230. As a result, the cover 120 compresses the container body 200 downward while shrinking the packing 260 to apply the sealing force.

When the rotating member 140 is completely engaged with the container body 200 and the packing 260 is pressed downward by the cover 120, the air passage 173 is closed by the packing 260. The pressing projection 148 presses the pressing surface 128 formed on the side surface of the cover 120, thereby closing the air passage 173, 174.

The packing 260 contracted by the cover 120 is completely in close contact with the container end portion 212 of the container frame 210 to provide a strong sealing force.

As described above, since the storage container 100 according to the present embodiment requires only one rotating member 140 to be coupled, it is easy to assemble. The storage container 100 having only one rotating member 140 has a simple structure and is easy to clean.

The storage container 100 according to the present embodiment is coupled to the container body 200 by the rotary member 140, the rear projection 130 and the side projection 160 provided symmetrically. Therefore, the cover 120 of the storage container 100 according to the present embodiment can be firmly coupled to the container body 200 even though only one rotating member 140 is provided.

The process of separating the cover 120 from the container body 200 corresponds to the reverse sequence of the process of attaching the cover 120. [ That is, when the rotary member 140 is pulled up, the cover 120 sequentially moves from the state of Figs. 14 to 15 to the state of Figs. 12 to 13 and the state of Figs. 10 to 11, ).

When the rotary member 140 is pulled up in the state shown in Figs. 14 to 15, the rotary locking projection 146 of the rotary member 140 starts to be separated from the rotary locking projection 222. Fig.

The pressing protrusion 148 releases the pressure on the pressing surface 128 of the cover 120 and the cover 120 releases the pressure against the packing 260. As a result, The air passage 129 is opened to allow air to flow into the container body 200. The air introduced into the container body 200 releases the vacuum pressure to facilitate the detachment of the cover 120. [

Due to the rise of the rotating member 140, the storage container 100 is in the state shown in Figs. 12 to 13. Fig.

When the rotary member 140 is further pulled up in the state of FIGS. 12 to 13, the pressing projection 148 presses downward the inside of the pressing projection insertion groove 224 to apply a force to lift the cover 120 upward. The cover 120 is moved in the lateral direction (the left direction in Figs. 12 to 13) and upward due to the upward force of the cover 120 by the pressing protrusion 148. [

By the continuous upward movement of the rotary member 140, the rotary lock projection 146 is completely separated from the rotary stopper 222 to be in the states shown in Figs. At this time, the cover 120 also enters the initial state by completing the lateral direction (the left direction in Figs. 10 to 11) and the upward movement. 10 to 11, the engagement of the rear projection 130 with the rotation locking projection 222 is released, and the engagement of the side projection 160 with the side engagement portion 230 is released. The air passages 129, 173 and 174 are completely opened.

Since the storage container 100 according to the present embodiment lifts up only one rotating member 140 as described above, the cover 120 can be easily separated from the container body 200. Particularly, in the ascending process of the rotary member 140, since the pressing projection 148 engages the pressing projection insertion groove 224 to move the cover 120 in the lateral direction and the upward direction, the cover 120 can be more easily It becomes possible to separate it.

In the storage container 100 according to the present embodiment, since the air passages 129, 173, and 174 are opened by the rise of the rotating member 140, the cover 120 can not be easily separated by the vacuum pressure Problems can also be solved.

The storage container 100 according to the present embodiment is illustrated in which the rotating member 140 is coupled to the cover 120 so that the cover 120 moves downward one by one during the locking process. However, the rotary member 140 may be coupled to the container body 200. In this case, the cover 120 is moved upward in the process of coupling the rotary member 140 to the cover 120. [
