DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout the specification and claims. The description will be omitted.

FIG. 1 is a perspective view illustrating a storage container 100 according to a first embodiment of the present invention, and FIG. 2 is an exploded perspective view of the storage container 100 illustrated in FIG. 1, the cover 110 of the storage container 100 illustrates a state in which the upper portion of the container body 160 is hermetically sealed.

1 and 2, the storage container 100 according to the present embodiment includes a cover 110, a pressing member 140, a container body 160, and a handle 180. The cover 110 is divided into a first cover 112 and a second cover 114 based on the folding line 116 and has a structure that can be folded in half. Further, the pressing member 140 is rotatably coupled on the folding line 116 on the upper surface of the cover 110.

The storage container 100 according to this embodiment can be opened or closed with respect to the container body 160 by the rotation direction of the pressing member 140. [ For example, when the pressing member 140 is positioned horizontally, the cover 110 can maintain the closed state (see FIG. 1), and when the pressing member 140 is positioned vertically, the cover 110 is opened (See FIG. 10).

The container body 160 has a rectangular parallelepiped shape and an open top surface. Thus, the container body 160 has four sides 162.

Although the storage container 100 according to the present embodiment has been described as having a rectangular parallelepiped shape, the present invention is not limited by the shape of the storage container 100. Accordingly, it is needless to say that the storage container 100 according to another embodiment of the present invention may have various shapes such as a cube, a circle, and an ellipse.

An upper rim 164 is formed at the upper end of the container body 160. The upper rim 164 protrudes slightly outward from the upper end of the side surface 162 and has an inner step 174 formed therein. The cover 110 is inserted inside the upper rim 164 to provide a sealing force. A side engaging groove 168 and an engaging groove 172 for reinforcing the engaging force with the cover 110 are provided on the inner surface of the upper rim 164.

The side latching grooves 168 correspond to the grooves into which the side projections 124 of the cover 110 are coupled. 9, when the cover 110 is coupled to the container body 160, the side projection 124 is caught in the side engagement groove 168. As a result, the sealing force of the cover 110 with respect to the container body 160 is enhanced.

The side engaging groove 168 has a lower inclined surface 170. When the side locking protrusion 124 is inserted into the side locking groove 168, it can not be easily removed by the lower inclined surface 170. Of course, when the cover 110 is folded to be opened, the side latching protrusions 124 can escape from the side latching grooves 168 by simultaneous contraction of the cover in the horizontal or horizontal and vertical directions.

The engaging groove 172 corresponds to the groove into which the engaging projection 126 of the cover 110 is inserted. The engaging grooves 172 are formed in positions and in the number corresponding to the engaging projections 126 formed on the outer rim 122 of the cover 110. [ The engaging projection 126 of the cover 110 is inserted into the engaging groove 172 when the cover 110 is unfolded and engaged with the container body 160. [ As a result, the engaging force of the cover 110 with respect to the container body 160 is strengthened.

A lever insertion groove 166 is formed at the center of the upper rim 164. The pair of lever insertion grooves 166 are mutually opposed to each other so that the head 150 of the pressing member 140 can be rotatably inserted. That is, when the cover 110 is closed as shown in FIG. 1, the head 150 is inserted into the lever insertion groove 166. At this time, the incision surface 152 formed on the head 150 is positioned horizontally to maximize the width of the head 150 in the horizontal direction, so that it does not fall out of the lever insertion groove 166. 10, when the cover 110 is opened, the cut-off surface 152 formed on the head 150 is positioned vertically, and the width of the head 150 in the horizontal direction is minimized, I will leave it.

The inner edge 174 formed in the interior of the container body 160 corresponds to a boundary separating the side edge 162 from the upper edge 164. In other words, the inner edge 174 corresponds to a portion slightly protruding outward from the upper end of the side surface 162, and the upper edge 164 projects vertically at the end of the inner edge 174. The outer rim 122 of the cover 110 and the packing 134 can be seated on the inner edge 174 when the cover 110 engages the container body 160.

Outwardly projecting flanges 176 are formed on two opposite side surfaces 162 of the container body 160. The flange 176 is formed with a pair of coupling grooves 178 to which the handle 180 can be coupled. The engaging grooves 178 are formed in an a-shaped and mutually symmetrical manner. The connecting portion 184 of the handle 180 is inserted into the engaging groove 178 and the engaging bar 188 of the handle 180 is caught by the lower portion of the flange 176. Accordingly, when the user desires to move the storage container 100, the user can lift the handle 180 and use it.

3 and 4 are a front view and a perspective view respectively illustrating the cover 110 of the storage container 100 according to the first embodiment of the present invention.

Referring to FIGS. 1 to 4, the cover 110 of the storage container 100 according to the present embodiment has a rectangular shape and a structure that is foldable in half with respect to the folding line 116. The cover 110 may be divided into a first cover 112 and a second cover 114 based on the folding line 116. The first cover 112 and the second cover 114 may be formed symmetrically with respect to the folding line 116. When the cover 110 is folded with respect to the folding line 116, the angle formed by the first cover 112 and the second cover 114 may be smaller than 180 degrees. In addition, when the cover 110 is unfolded, the first cover 112 and the second cover 114 may both be horizontally positioned to form one plane.

The folding line 116 allows relative rotation while connecting the first cover 112 and the second cover 114. Accordingly, the folding line 116 is formed relatively thinner than the first cover 112 and the second cover 114 and can be deformed with a constant width. As such, the folding line 116 corresponds to a thinly formed elastic deformation section.

3, the folding line 116 has a straight line shape when seen from the front, but it may have various shapes such as a curved line. The width a of the folding line 116 is set such that the first cover 112 and the second cover 114 expand or contract in the horizontal direction in the course of coupling the cover 110 to the container body 160 You can determine the distance you can.

When the cover 110 is coupled to the container body 160, the side projections 124 may overlap with the side latching grooves 168 by a length a (not shown) The side projection 124 shown). At this time, when the cover 110 is further pushed downward, the folding line 116 is contracted and the side projection 124 is slightly retracted in the direction of the arrow, and can be sloped downward on the upper slope 171. When the side projection 124 is in contact with the lower inclined surface 170, the folding line 116 is restored to its original shape due to the elastic restoring force. This causes the side projection 124 to advance in the direction opposite to the arrow, (168).

Even when the cover 110 is detached from the container body 160, the side projection 124 can be detached from the side latching groove 168 by contraction and restoration of the folding line 116. [

Thus, the length of the side projection 124 in the side engagement groove 168 is proportional to the overlapping length shown in FIG. 9, and the width of the folding line 116 can also increase.

The cover 110 may be formed integrally with the first cover 112, the second cover 114, and the folding line 116 by injection molding. In addition, the inclined surface 117 inclined downwardly adjacent to the folding line 116 may be formed symmetrically.

Although the cover 110 of the storage container 100 according to the present embodiment is illustrated as having one folding line 116, the storage container according to another embodiment of the present invention includes two or more folding lines 116 . Although the folding line 116 in the storage container 100 according to the present embodiment is formed at the center of the cover 110, the storage container according to another embodiment of the present invention is asymmetric with respect to the cover 110 As shown in FIG.

On the upper surface of the cover 110, an upper surface projection 118 is formed symmetrically with respect to the folding line 116. The upper surface protrusions 118 are formed adjacent to one end and the other end of the folding line 116, respectively. Therefore, all the upper surface protrusions 118 are formed on the upper surface of the cover 110. The upper surface protrusions 118 are protruded from the cover 110 with a constant height.

An arc-shaped connecting member 120 is formed on the upper surface protrusion 110. The connecting member 120 is positioned on the folding line 116 and is joined at both ends to the upper surface protrusion 110 located on both sides of the folding line 116. The connecting member 120 may be formed thin as the folding line 116 to be deformable, thereby enabling the cover 110 to be folded. In addition, the connecting member 120 prevents the pressing member 140 from being detached from the cover 110.

The cover 110 has a vertically formed outer rim 122 at its top edge. The outer rim 122 has a constant height to prevent contamination by preventing the inner surface of the cover 110 from contacting the bottom surface. The outer rim 122 is not formed adjacent the folding line 116, which allows the cover 110 to be folded relative to the folding line 116.

The outer rim 122 is inserted into the upper rim 164 of the container body 160 and seats in the inner rim 174 when the cover 110 engages the container body 160.

An inner rim 128 is formed at an interval inside the outer rim 122. The packing 134 is inserted into the packing groove 130, which is an empty space formed between the outer rim 122 and the inner rim 128.

The packing 134 protrudes somewhat as compared to the outer rim 122 and the inner rim 128 to pressurize the inner edge 174 of the container body 160 and thereby the sealing force of the cover 110 can be maintained. In addition, the packing groove 130 may have a zigzag structure so that the packing 134 is not easily separated. In particular, such a zig-zag structure may be formed adjacent the folding line 116.

The inner rim 128 is not formed adjacent the folding line 116, which allows the cover 110 to fold relative to the folding line 116. The inner rim 128 and the outer rim 122 may have the same height.

A side surface protrusion 124 is formed on an outer side surface of the outer rim 122. The side projections 124 may be formed symmetrically on the two sides of the four sides of the outer rim 122 perpendicular to the folding line 116. The side projections 124 are engaged with the side engaging grooves 168 provided on the inner surface of the upper edge 164 of the container body 160 when the cover 110 is engaged with the container main body 160 9). As a result, the engaging force of the cover 110 with respect to the container body 160 is strengthened.

The side projection 124 has an inclined surface 125 formed thereon. The inclined surface 125 is formed to be inclined downward in the outward direction of the cover 110 from the folding line 116. The inclined surface 125 allows the side surface projection 124 to be easily inserted into the side surface latching groove 168.

A locking protrusion 126 may be formed on two surfaces of the outer rim 122 parallel to the folding line 116. That is, since the engaging projections 126 are formed on the other side of the side rim 124 and the outer rim 122, they are arranged vertically. The locking protrusions 126 may be formed at the central and both corner portions of the outer rim 122, respectively. The engaging projection 126 may be inserted into the engaging groove 172 formed in the upper edge 164 of the container body 160 when the cover 110 is coupled to the container body 160. [ As a result, the engaging force of the cover 110 with respect to the container body 160 is strengthened.

The cover 110 may be integrally formed with the first cover 112, the second cover 114, the folding line 116, and the connecting member 120. For example, the cover 110 may be integrally formed by plastic injection molding or the like.

5 is a perspective view illustrating an engaging portion 144 of the urging member 140 of the storage container 100 according to the first embodiment of the present invention and FIG. 6 is a perspective view illustrating the engaging portion 144 of the urging member 140 (144). &Lt; / RTI >

2 and 5 to 6, the pressing member 140 rotatably engages with the upper surface of the cover 110, and determines the opening and closing of the cover according to the rotating direction thereof. The pressing member 140 has a U-shaped main body 142 and engaging portions 144 provided at both ends of the main body 142 and rotatably engaged with the cover 110.

The main body 142 is a portion gripped by the user, and the length thereof may be formed corresponding to the size of the cover 110. 1, when the cover 110 closes the container body 160, the body 142 can be brought into close contact with the upper surface of the cover 110. As shown in FIG.

The engaging portion 144 includes a body 146 and a head 150.

The body 146 protrudes inward of the pressing member 140 and is provided with a body groove 148 having a cylindrical shape and recessed at one side thereof. The angled body groove 148 allows a portion of the cover 110 to be received and folded when the cover 110 is open. Therefore, the body groove 148 is located opposite to the upper surface of the cover 110 when the pressing member 140 is vertically positioned to open the cover 110 (see FIG. 11).

The body 146 is rotatably inserted into the connecting member 120 provided on the cover 110 so that the pressing member 140 is not separated from the cover 110 (see FIG. 11).

The head 150 has a structure in which two cut-out surfaces 152 parallel to each other are formed around the cylindrical portion, the portion being led outward from the pressing member 140. When the pressing member 140 is positioned vertically (see FIG. 10), the cut-off surface 152 of the head 150 is disposed perpendicular to the bottom surface, and the horizontal width of the head 150 is minimized. Thus, the head 150 can be inserted into and released from the lever insertion groove 166 formed in the container body 160. 1), the cut-off surface 152 of the head 150 is arranged in parallel with the bottom surface, and the width of the head 150 in the horizontal direction is the maximum . The head 150 further functions to increase the sealing force of the cover 110 with respect to the container body 160 without being detached from the lever insertion groove 166 formed in the container body 160. [

Referring to FIG. 1, when the cover 110 is closed, the end of the head 150 is located outside the upper edge 164 of the container body 160. That is, the end of the head 150 protrudes out of the lever insertion groove 166, so that the upper rim 164 can be caught by the lower surface of the head 150. This makes it possible to solve the problem that the side surface 162 is opened when a load is applied as in the movement of the storage container 100 and the side surface protrusion 124 is deformed by the deformation of the patent side surface 162, Can be solved.

The pressing member 140 can be made separately from the cover 110 by plastic or metal. When the pressing member 140 is formed of a material having elasticity as described above, the width of the pressing member 140 when the cover member 110 is coupled with the cover 110 is elastically expanded so that the engaging portion 144 is connected to the connecting member 120 of the cover 110, Respectively.

7 is a front view illustrating the handle 180 of the storage container 100 according to the first embodiment of the present invention.

1 to 2 and 7, the knob 180 has a rectangular shape, and a hole is formed at the center of the knob 180 so that a user's hand can be inserted. The handle 180 has a grip portion 182, a pair of connecting portions 184, and a latching bar 188.

The grip portion 182 is positioned on the flange 176 of the container body 160 as a portion that can be gripped by the user. Referring to FIG. 1, when the cover 110 is closed, the handle 180 is lowered so that the grip portion 182 can contact the upper surface of the flange 176. When the storage container 100 is to be moved, the handle 180 is lifted so that the grip portion 182 can be positioned at a predetermined height from the flange 176. [

The connection portion 184 connects the grip portion 182 and the engagement bar 188. The connecting portion 184 is inserted into the coupling groove 178 formed in the flange 176 and can move up and down. In addition, an elastic section 186 having a somewhat thin thickness is formed at the lower end of the connection section 184. The elastic section 186 is a portion where a deformation load (a load that buckles or narrows the pair of knobs 180) is concentrated when the storage container 100 is lifted by holding the knob 180. The elastic section 186 thus prevents the connection portion 184 from being deformed in its entirety. In this way, the connecting portion 184 is prevented from being deformed (bent) as a whole, so that the handle 180 can be easily inserted into the flange 176 and the state shown in Fig. 1 can be formed.

The latching bar 188 is formed parallel to the grip portion 182 by interconnecting the pair of connection portions 184. And the latching bar 188 corresponds to the portion of the flange 176 which is caught by the lower portion. As a result, the handle 180 is prevented from being detached from the flange 176, and the handle 180 can be gripped to lift or move the storage container 100.

Hereinafter, the storage container 100 according to the present embodiment will be described in more detail with reference to FIG. 1 and FIGS. 8 to 11. FIG.

8 is a view illustrating a state in which the cover 110 is closed by the pressing member 140 in the storage container 100 according to the first embodiment of the present invention. And the side projections 124 are caught in the side engagement grooves 168. As shown in Fig. 10 is a perspective view illustrating a state in which the cover 110 is folded and opened in the storage container 100 according to the first embodiment of the present invention and FIG. 11 is a perspective view illustrating a state in which the pressing member 140, the cover 110, Fig.

8, the opening and closing member 140 is shown in a sectional view for convenience of explanation.

When the cover 110 seals the mouth of the container body 160, the cover 110 is in a fully extended state. Accordingly, the first cover 112 and the second cover 114 can be located on the same plane. At this time, the outer edge 122 of the cover 110 is completely inserted into the upper edge 164 of the container body 160 and is prevented from being lowered while being caught by the inner edge 174.

The side surface protrusion 124 formed on the outer edge 122 of the cover 110 is caught and placed on the lower side of the side catching groove 168 when the cover 110 seals the inlet of the container body 160 9). The engaging projection 126 formed on the outer frame 122 of the cover 110 is also inserted into the engaging groove 172. Such a side projection 124 and the engagement protrusion 126 engage with the container body 160 to enhance the sealing force of the cover 110. [

When the cover 110 seals the mouth of the container body 160, the pressing member 140 is positioned horizontally as illustrated in Fig. At this time, among the engaging portions 144 of the pressing member 140, the body 146 presses the folding line 116 and the inclined surface 117 formed on both sides downward (see FIG. 8). As such, when the engaging portion 144 of the pressing member 140 presses the folding line 116 and / or the periphery of the cover 110 downward while the cover 110 is in the closed state, So that the sealing force can be maintained.

When the engaging portion 144 presses the folding line 116 and / or its periphery, the body 146 of the engaging portion 144 is inserted into the connecting member 120 and receives a constant pressure, It is possible to rotate only when it is applied.

When the cover 110 seals the inlet of the container body 160, the grip 180 can be held down on the upper surface of the flange 176 by the grip portion 182. [

1, in order to separate the cover 110 from the container body 160 and open the inlet of the container body 160, the pressing member 140 positioned horizontally is rotated and positioned vertically. Thus, a space is formed in which the cover 110 can be folded while the body groove 148 of the engaging portion 144 is opposed to the folding line 116 (see FIG. 11). The cutout surface 152 formed in the head 150 of the engaging portion 144 is vertically positioned so that its horizontal width is minimized and can be separated from the lever insertion groove 166. [

The side projection 124 is detached from the side engagement groove 168 and the engagement projection 126 is released from the engagement groove 172 and the head 150 Is released from the lever insertion groove 166, so that the cover 110 is folded with respect to the folding line 116. As a result, the engagement of the cover 110 with respect to the container body 160 is released and the cover 110 is opened as illustrated in Fig.

The folding line 116 can be contracted by the force of pulling up the cover 110 and the side projection 124 can be separated from the side engagement groove 168 by the contraction of the folding line 116. [

When the cover 110 is folded, the first cover 112 and the second cover 114 form an angle, and the angle is reduced as the cover 110 is folded. As the cover 110 is folded, the packing 134 is also elastically folded together.

The angle at which the cover 110 is folded can be determined according to the size of the body groove 148 formed in the engaging portion 144. Referring to FIG. 11, since a part of the folded portion of the cover 110 is inserted into the body groove 148, the larger the body groove 148 is formed, the larger the amount of folding of the cover 110 is.

When the cover 110 is opened and the grip 182 of the handle 180 is held and pulled up, the engagement bar 188 is caught by the lower surface of the flange 176. Thus, the storage container 100 can be moved using the handle 180. [ Further, even if the force for enlarging or reducing the width between the pair of knobs 180 is applied by the user, the elastic section 186 of the connecting portion 184 is intensively deformed and the other portions are deformed or relatively deformed Less. Therefore, since most of the connecting portion 184 maintains a straight line shape, it becomes easy to insert the knob 180 later as shown in FIG.

As described above, the storage container 100 according to the present embodiment is advantageous in that it can be opened by a single operation because the cover 110 is folded and separated by pulling the pressure member 140 upwards, .

The outer rim 122 of the folded cover 110 is gripped by the upper rim 164 of the container body 160 while the pressing member 140 is gripped to seal the container body 160 again by the cover 110. [ . When the cover 110 is pressed downward, the cover 110 is stretched so that the side projection 124 is caught in the side latching groove 168 and the latching projection 126 is inserted into the latching groove 172, ) Is completely opened. When the vertically positioned pressing member 140 is rotated to be horizontally positioned, the outer circumferential surface of the body 146 of the engaging portion 144 is moved downward along the folding line 116 and the inclined surface 117 formed therearound, So that the cover 110 is not easily folded while being pressed.

The cover 110 is fully opened so that the first cover 112 and the second cover 114 are horizontal so that the sealing of the cover 110 with respect to the container body 160 is achieved.

The side projections 124 overlap the upper inclined surface 171 formed on the upper surface of the side engaging groove 168 in the process of being engaged with the side engaging grooves 168, At this time, the thin folding line 116 is slightly contracted by the downward pressing force and the inclined contact, and the side projection 124 is moved downward along the upper inclined face 171 and can be lowered to contact the lower inclined face 170.

Since the rotatable urging member 140 is provided on or near the folding line 116, the storage container 100 according to the present embodiment can prevent the first cover 112 and / 2 is characterized by a convenient structure in which one-touch opening and closing is possible so as to close or unseal the container body 160 by expanding or folding the cover 114.

The cover 240 can be detached from the container body 210 by folding the cover 240 based on the folding line 252 as illustrated in FIG. The cover 240 can be coupled to the container body 210 by spreading the cover 240 with respect to the folding line 252 and hooking the end of the cover 240 to the latching groove 220 of the latching portion 216 .

A folding groove 254 having a predetermined depth is formed on the lower surface of the cover 240. The folding groove 254 corresponds to a groove formed so as to penetrate the entire cover 240 transversely or longitudinally. By such folding grooves 254, the cover 240 can be folded or unfolded with respect to the folding line 252.

The folding groove 254 is formed only on the lower surface of the cover 240 (the opposite surface of the upper surface 242 on which the pressing member 244 is formed). Therefore, the cover 240 has a structure that can be folded in the direction in which the folding grooves 254 are formed.

Of course, the cover of the storage container according to another embodiment of the present invention may have a structure that can be folded in both directions.

The range in which the cover 240 can be folded by the folding groove 254 can be determined. That is, referring to FIG. 3, when the cover 240 is in the maximum folded state, the left and right folding surfaces 255 may contact each other, so that the cover 240 may not be folded any more. In this way, the folding groove 254 can serve as a stopper for restricting the folding of the cover 240.

A pressing member 244 is provided on the upper surface 242 of the cover 240. The pressing member 244 is provided to maintain the unfolded state of the cover 240 and can be integrally formed with the cover 240 by plastic injection molding. The pressing member 244 has a rotating hinge 246, a locking protrusion 248, and a pressing protrusion 250.

The rotation hinge 246 corresponds to the rotation center of the pressing member 244 and may correspond to a portion formed thinly in the pressing member 244. [ The storage container 200 according to the present embodiment is arranged such that the rotating hinge 246 is spaced apart and spaced apart from the folding line 252 at regular intervals. As a result, when the pressing member 244 is engaged with the upper surface 242 of the cover 240, the pressing member 244 covers the folding line 252 as illustrated in FIG.

On the inner surface of the pressing member 244, a locking protrusion 248 and a pressing protrusion 250 are provided.

The locking protrusion 248 has a shape and corresponds to a portion which is inserted into the locking groove 256 formed on the other side of the rotary hinge 246 with respect to the folding line 252. The pressing member 244 is placed on the upper side of the folding line 252 and is engaged with the upper surface 242 of the cover 240 so that the cover 240 is not folded. The cover 240 is not folded by the pressing member 244 so that the cover 240 can maintain the engagement with the container body 210 as shown in Figs.

In the storage container according to another embodiment of the present invention, a locking groove is formed in the pressing member, and the locking projection may be formed on the upper surface of the cover. Further, the storage container according to another embodiment of the present invention can be combined with the cover by various methods, for example, by a Velcro, a magnet, a vacuum adsorption device .

The pressing projection 250 is protruded from the inner surface of the pressing member 244. When the pressing member 244 is engaged with the upper surface 242 of the cover 240, the pressing protrusion 250 presses the upper surface 242 while being positioned on the folding line 252. As a result, the cover 240 can be maintained in the unfolded state.

The pressing member 244 may be formed of the same material (for example, plastic resin) as that of the cover 240. The pressing member 244 is engaged with the cover 240 to maintain the unfolded state of the cover 240 as illustrated in Figure 13 so that the coupling state with respect to the container body 210 can be maintained .

Although the storage container 200 according to the present embodiment is illustrated as having one pressing member 244, two or more pressing members may be provided depending on the size of the cover 240. [ In addition, the storage container according to another embodiment of the present invention may include a handle.

Hereinafter, a storage container 300 according to a third embodiment of the present invention will be described with reference to FIGS. 15 to 19. FIG.

Figs. 15 and 16 illustrate a storage container 300 according to a third embodiment of the present invention, in which the cover 310 is coupled to the container body 360. Fig. 15 illustrates a state before the pressing member 340 presses the cover 310 and the knob 390 is engaged and FIG. 16 illustrates a state in which the pressing member 340 is separated and the knob 390 is engaged .

15 to 16, a storage container 300 according to a third embodiment of the present invention includes a container body 360, folding lines 316 and folding lines 316 that enable folding, A cover 310 integrally formed of a first cover 312 and a second cover 314 provided at the upper portion of the folding line 316, 310) to unfold the container body (360) to unfold the container body (360). The cover 310 is folded on the basis of the folding line 316 while the first cover 312 and the second cover 314 are engaged with the container body 360 while being folded on the folding line 316, 1 cover 312 and the second cover 314 are separated from the container body 360.

As described above, the storage container 300 according to the third embodiment is the same or similar in construction and operation to the storage container 100 according to the first embodiment. The storage container 300 according to the third embodiment differs from the storage container 100 according to the first embodiment in the combination of the pressing member 340 and the cover 310 and the configuration of the handle 390 .

On the upper surface of the cover 310, a U-shaped upper surface projection 318 is protruded. The upper surface protrusions 318 are formed such that the two protrusions 318 face each other. One upper surface projection 318 extends from the end of the cover 310 to the folding line 316 and a body groove 320 is formed on the side surface thereof. The other top surface protrusion 318 is formed to have a relatively short length and is spaced apart from the other top surface protrusions 318 by a certain distance. When the pressing member 340 is in close contact with the upper surface of the cover 310 to press the cover 310, the U-shaped pressing member 340 is inserted in the space between the two upper surface protrusions 318, ).

A body groove 320 is formed on one side of the two upper surface protrusions 318. A body 346 of the pressing member 340 is rotatably inserted into the body groove 320.

The storage container 300 according to the third embodiment has a handle 390 having a T shape. The handle 390 has a grip portion 392 corresponding to a portion to be held by the user and a coupling portion 394 formed perpendicularly to the grip portion 392. [ A pin insertion hole 396 is formed in the lower end of the coupling portion 394.

A flange 376 to which the handle 390 is coupled is formed on the upper edge 364 of the container body 360 and a coupling hole 378 into which the coupling portion 394 is inserted is formed in the flange 376 . A handle cover 380 is formed on the lower portion of the flange 376 to prevent the engaging portion 394 of the handle 390 from being exposed to the outside.

The pin insertion hole 396 is formed to have a larger thickness than the other portions of the engaging portion 394. However, the thickness of the pin insertion hole 396 can be reduced in order to pass through the coupling hole 378. [ For example, a cutting groove (not shown) may be formed in the inside of the coupling hole 378 and then the pressing hole may be formed by pressing the pressing groove to reduce its thickness or to be formed of a material having elasticity (elastic plastic, metal or rubber) Can be reduced. After the thickness of the pin insertion hole 396 is reduced and passed through the coupling hole 378, the coupling pin 398 is inserted into the pin insertion hole 396. [ The engagement pin 398 serves to prevent the thickness of the pin insertion hole 398 from being reduced. As a result, the pin insertion hole 396 does not come out of the coupling hole 378, so that the knob 390 is caught by the flange 376 and does not come off.

When a cutout groove is formed in the pin insertion hole 396, a pin projection (not shown) inserted into the cutout groove may be formed around the joint pin 398. The pin projection prevents the engagement pin 398 from being easily detached from the pin insertion hole 396.

When the handle 390 is not used, the engaging portion 394 is inserted into the handle cover 380 and is not exposed to the outside (see FIG. 16). When the handle 390 is used, the engaging portion 394 protrudes to the outside of the handle cover 380 to facilitate grasping of the grip portion 392. At this time, the pin insertion hole 396 of the coupling portion 394 is caught by the flange 376 in a state where the coupling pin 398 is inserted, thereby preventing the knob 390 from being detached.

The handle 390, the flange 376, the coupling hole 378 and the handle cover 380 may be provided symmetrically with respect to the folding line 316, one on the left and one on the right.

The urging member 340 has a U-shaped main body 342 and engaging portions 344 provided at both ends of the main body 342.

The main body 342 corresponds to a portion gripped by the user. The body 342 has a pressing rib 343 formed along the lower edge thereof. When the pressing member 340 hermetically seals the cover 310, the pressing rib 343 presses the holding protrusion (see 317 in Fig. 18) formed on the upper surface of the cover 310. [

The engaging portion 344 allows the urging member 340 to be rotatably coupled to the cover 310. The engaging portion 344 has an inwardly protruding circular body 346, an outwardly projecting head 348, and a laterally projecting engaging projection 352.

The body 346 is rotatably inserted into the body groove 320 formed on the side surface of the upper surface projection 318.

The head 348 is rotatably inserted into a lever insertion groove 366 formed in an upper rim 364 of the container body 360. The head 348 has a head inclined surface (not shown) and its diameter increases toward the end. Therefore, the end of the head 348 is caught by the upper edge 364, thereby preventing the container body 360 from being deformed and spreading, thereby weakening the sealing force of the cover 310.

The container body 360 according to the third embodiment has a rectangular parallelepiped shape with an opened top surface and a hollow space formed therein. An upper edge 364 is formed at the upper end of the four side surfaces 362. The upper edge 364 is formed with a lever insertion groove 366 and a flange 376 into which the head 348 of the pressing member 340 is rotatably inserted. An upper protrusion 365 is formed at a portion of the upper rim 364 where the flange 376 is formed. The upper protrusions 365 are formed symmetrically with respect to the folding line 316, and may be partially formed with a protruding shape without being continuously formed.

17 is a view for explaining a process of coupling the cover 310 to the container body 360 in the storage container 300 according to the third embodiment of the present invention.

17, the upper projection 365 is formed so as to protrude inward from the upper end of the upper rim 364 (toward the folding line 316). In addition, an inclined surface 367 is formed in the lower portion of the upper projection 365. The end of the cover 310 is guided by the inclined surface 367 and is caught by the lower portion of the upper projection 365 when the cover 310 is extended with respect to the folding line 316. The upper protrusion 365 serves to prevent the cover 310 from being tilted with respect to the container body 360 when the cover 310 is engaged with the container body 360.

The container body 360 has an inner step 374 and a side engaging groove 368. This is because the inner edge 174 and the side engaging groove 168 of the container body 160 according to the first embodiment, And coupling are the same or similar, so a detailed description will be omitted.

18 is a view illustrating a state before the cover 310 covers the upper portion of the container body 360 and is pressed by the pressing member 340 in the storage container 300 according to the third embodiment of the present invention to be. 19 is a view illustrating a state in which the cover 310 is pressed by the pressing member 340 in Fig.

18 and 19, the rectangular box corresponds to a part of the cover 310 and the urging member 340 around the folding line 316 and an enlarged cross-sectional view thereof. 18 and 19, the engaging portion 394 of the handle 390 is inserted into the inside of the handle cover 380. Further,

Referring to FIGS. 18 and 19, a retaining projection 317 is protruded upward from a top surface of the cover 310 at a position adjacent to the folding line 316. Two retaining protrusions 317 may be formed on the upper surface of the cover 310. Further, the retaining projection 317 may be formed with an inclined side surface.

When the pressing member 340 rotates to come into contact with the upper surface of the cover 310 as shown in Fig. 19, the pressing rib 343 of the pressing member 340 moves the holding protrusion 317 in the lateral direction (right direction in Fig. 19) And downward. As a result, the cover 310 can be kept unfolded.

A cover insertion groove 332 may be formed in an upper portion of the packing groove 330 of the cover 310.

The engaging projection 352 of the pressing member 340 can be inserted into the cover insertion groove 332 when the pressing member 340 rotates and contacts the upper surface of the cover 310 as shown in Fig. This prevents the side surface 362 of the container body 360 from being opened and the sealing force of the cover 310 is lowered. Of course, since the head 348 of the pressing member 340 is also caught in the upper edge 364 of the container body 360, the side surface 362 of the container body 360 is prevented from being deformed or the like.
