Description

Food Vessel

The present invention relates to a food storage container, and more particularly, to a food storage container made of synthetic resin so that food can be safely stored without odor or leakage of water.

In general, when the food is stored, its unique smell and moisture is leaked out, and in order to prevent this, the food is stored in a sealed container and stored in a refrigerator.

As shown in FIG. 1, the conventional hermetically sealed container includes a case 1 having an open top, a cover 2 for opening and closing the case 1, and an opening of the case 1 with the cover 2 open. It is equipped with a lock knob (3) for locking in the part.

The case 1 usually consists of a rectangular cylinder to form a storage space therein. In addition, a locking protrusion 4 is provided at an open end of the four side walls 1a and 1b of the case 1, and the locking protrusions 4 are respectively formed along the outer surface of the side wall 1a and 1b of the case 1. It is formed to protrude two by one.

Alternatively, a sealing groove (not shown) is formed at the bottom of the cover 2 along the edge, such that the open end of the case 1 is inserted into the sealing groove.

And the locking handle (3) is integrally formed on the four sides of the cover (2) so as to pivot outward (refer to the arrow direction), respectively, two locking holes (5) are formed to correspond to the locking projection (4) have.

Therefore, food is put in the storage space of the case 1, and the cover 2 is covered. In such a state, each of the locking knobs 3 provided on the cover 2 is pushed downward, and the locking protrusions 4 provided on the side walls 1a and 1b of the case 1 are elastically coupled to the locking holes 5. The cover 2 is securely locked. Then, when the four locking handles 3 are lifted upwards, the restraints of the locking protrusions 4 are released, thereby opening the cover 2.

However, in the conventional hermetically sealed container, since the locking protrusion 4 is formed to protrude from the side walls 1a and 1b of the case 1, there is a disadvantage in that its external appearance is inferior. In addition, there is a problem that is caught when cleaning the case 1 by the protruding locking projections (4). That is, when the case 1 is washed through a scrubber or the like, the locking protrusions 4 protruding along the sidewalls 1a and 1b of the case 1 serve as obstacles.

In addition, the locking hole (5) is formed in the locking handle (3) exposed to the outside, there is a risk that foreign matter is caught in the lock hole (5) there is a disadvantage that the product reliability is lowered.

The present invention is to solve this problem, an object of the present invention is to improve the locking handle and its locking structure to make the appearance of the storage container more beautiful and to provide a food storage container that can maximize its ease of use more will be.

In addition, another object of the present invention is to provide a food storage container that can be maintained more securely the locked state of the lock handle.

The sealing groove 21 has a ring-shaped silicon packing 22 is interposed. Therefore, when the sealing part 14 is inserted into the sealing groove 21, the silicon packing 22 is pressed and the cover 20 is hermetically coupled to the open end of the case 10.

Meanwhile, referring to FIGS. 3 to 5, the locking handles 30 are symmetrically in front, rear, left, and right sides of the cover 20 to be opened and closed by the user by hand, and the detailed structure thereof is as follows. (The locking structures of the locking knobs 30 provided along the four sides of the cover 20 are all the same. Hereinafter, only the locking knob structures provided on the left and right sides of the cover 20 will be described.)

First, the locking handles 30 are provided at the central portions of the four sides of the cover 20 so as to be locked by walking along the flange 15 of the case 10. That is, the locking handle 30 is integrally formed with the same material on the side of the cover 20, and can be turned up and down along the boundary portion 32 with the cover 20 (arrows A and B in FIG. 5). Prepared. As such, the boundary portion 32 of the locking handle 30 functions as a hinge because the cover 20 and the locking handle 30 are injection molded through a synthetic resin having a predetermined elastic force.

In addition, the locking handle 30 is an elastic locking portion 31 surrounding the bottom 16 of the flange 15 in the locking process, and the locking groove of the flange 15 while elastically deforming the elastic locking portion 31. 17 is defined as a stiffening protrusion 34 coupled with the curved projection 34 and an extension portion 35 that is curvedly extended so that the user can press or lift the locking handle 30 by hand.

The elastic locking portion 31 surrounds the bottom surface 16 of the flange 15 in the process of turning the locking handle 30 downward from the boundary portion 32 (arrow A direction of FIG. 5; locking process). It is formed to be bent, the upper surface 33 of the elastic engaging portion 31 is positioned to correspond to the bottom surface 16 of the flange 15 when fully turned.

And the locking projection 34 is provided to protrude in the horizontal direction on the upper surface 33 of the elastic locking portion 31 is elastically coupled to the locking groove 17, for this purpose, the elastic locking portion in a shape corresponding to the locking groove 17 An upper surface 33 of 31 is provided. That is, the upper surface of the locking protrusion 34 is inclined in the opposite direction to the first inclined surface 17a of the locking groove 17 so as to be in surface contact with the inner surface of the locking groove 17 when the locking handle 30 is locked. It consists of the inclined surface 34a.

Next will be described the locking operation and the effects of the locking handle according to the present invention configured as described above.

First, put the food to be stored in the storage space 11 of the case 10 and covers the cover 20 to its opening. That is, the cover part 20 covers the cover 20 so that the sealing part 14 of the case 10 is inserted into the sealing groove 21 in which the silicon packing 22 is embedded. In this way, the cover 20 covered with the preliminary does not move in the front and rear and left and right directions because the sealing portion 14 is inserted into the sealing groove 21.

6 and 7, in this state, pressing down the extension portion 35 of the locking handle 30 in the downward direction, the locking handle 30 is pressed the boundary portion 32 of the rectangular cover 20. It turns in the direction of arrow A to the starting point. Therefore, the elastic locking portion 31 is elastically deformed to surround the bottom face 16 of the flange 15 and at the same time the locking projection 34 is inserted into the locking groove 17 of the flange 15, respectively. At this time, the second inclined surface 34a of the locking protrusion 34 is firmly coupled while being in surface contact with the first inclined surface 17a of the locking groove 17 and is not disassembled unless an artificial force is applied.

As such, the locking protrusion 34 is elastically coupled to the locking groove 17 in a one-touch manner so that the locking handle 30 is kept locked and at the same time the cover 20 is more firmly sealed.

On the other hand, when holding the extension 35 of the locking handle 30 and lifted it upwards, the elastic locking portion 31 of the locking handle 30 is deformed elastically and the locking protrusion 34 is removed from the locking groove 17. Come out. Accordingly, the cover 20 may be easily opened by releasing the locked state of the lock knob 30.

At this time, even if the cover 20 is disassembled, since the case 10 is configured so that the locking structure with the locking knob 30 does not protrude to the outside, its external aesthetics are more beautiful and, of course, the case 10 of the case 10. Washing can be made easier.

On the other hand, the technical idea has been described as an example of a food storage container made of a square, but is not limited to this, of course, the case may be applied to a food storage container made of a cylindrical.

As described above in detail, according to the food storage container according to the present invention, the flange of the case is provided with a locking groove formed in the longitudinal direction on the inner surface in the longitudinal direction, the locking handle is second to be caught while being elastically deformed in the locking groove It is provided so that the protrusion which inclined surface was formed may protrude. Accordingly, while the first inclined surface and the second inclined surface are in contact with each other, there is an advantage that the locking knob is more securely maintained in the locked state.

In addition, since the locking structure of the locking handle is not made to protrude to the outside, its external aesthetics are more beautiful and can be easily washed, thereby maximizing the convenience of use. In addition, there is no fear of foreign matter caught in the locking structure of the locking handle has the advantage that the product reliability is more improved.
