Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a closed container and a mold for forming the closed container according to the present invention will be described.

Figure 2 is a perspective view showing a closed container 30 according to the present invention, Figure 3 is a partial cross-sectional view taken along line I-I of Figure 2, showing the process of the binding opening and closing lid 32 is bound.

As shown in the figure, the airtight container 30 of the present invention includes a container body 34 and a fastening opening / closing lid 32 covering an upper surface of the container body 34 opening 16.

The flange 36 is formed along the outer circumference of the opening 16 so that the closure opening lid 32 can be attached to the container body 34. The binding opening and closing lid 32 is disposed and fixed with a space | interval D in the width direction of the lock wing 38 in the lock wing 38 extended so that rotation to the edge, and the distal end surface of the lock wing 38 is possible. Consists of the upper and lower support protrusions (40, 42).

In this embodiment, an arc-shaped recessed groove 44 is formed on the upper surface of the flange 36. And an arc-shaped convex protrusion 46 is formed at the end of the upper support protrusion 40 to be coupled to the concave groove 44. At this time, the convex protrusion 46 is bent obliquely toward the direction of the lower support protrusion 42.

In FIG. 3, reference numeral 48 denotes a 'confidential packing'.

In the present embodiment, the inner surface of the concave groove 44 and the outer surface of the convex protrusion 46 have been described as curved surfaces having an 'arc' shape, but are not limited thereto. That is, the concave groove 44 can accommodate the convex protrusion 46 sufficiently, and can be any shape as long as it is formed in a smooth curved surface so that the convex protrusion 46 can smoothly escape from the concave groove 44 at the time of disassembly. Do.

In addition, the convex protrusion 46 is also described as being bent toward the direction of the lower support protrusion 42, but is not limited thereto. That is, if the upper surface of the flange 36 can be pressed, the convex protrusion 46 may be formed to be in a state parallel to the upper support protrusion 40 without being formed bent.

According to the locking structure of the hermetically sealed container according to the present embodiment as described above, the binding opening and closing lid 32 is disposed in a state covering the opening 16 of the container body 34, and rotates the lock wing 38 in the locking direction. The lock is made in such a way that the flange 36 of the container body 34 is coupled between the upper and lower support protrusions 40 and 42 provided on the lock wing 38.

When explaining the above locking process in more detail, while the convex protrusion 46 is moved toward the concave groove 44 while meeting the upper surface of the flange 36, the upper support protrusion 40 is the interval (D) of the initial state It is a little more wide open.

And while the convex protrusion 46 is moved to the concave groove 44 side, the flange 36 is coupled in a state that is naturally inserted between the upper and lower support protrusions 40, 42, wherein the convex protrusion 46 is concave Home 44 is met.

When the convex protrusion 46 meets the concave groove 44 as described above, the convex protrusion 46 is accommodated in close contact with the concave groove 44 by the restoring force of the upper support protrusion 40 that has been opened, and the arc-shaped curved surfaces are circumscribed to each other. To interlock. That is, the convex protrusion 46 presses the flange 36 in the engaged state in which the upper and lower support protrusions 40 and 42 hold the upper and lower surfaces of the flange 36 and the concave groove 44. By the combined action such as the catching phenomenon, the binding closure lid 32 and the container body 34 can be maintained in a secure locked state or a secure engagement state.

In particular, since both the convex protrusion 46 and the concave groove 44 are formed in an arc-shaped curved surface, when the lock wing 38 is folded outward in the engaged state, the convex protrusion 46 is formed from the concave groove 44. Gently breaks out.

And after the convex protrusion 46 is slightly out of the concave groove 44, the sliding motion is made more smoothly, so that the locking wing 38 is easily removed from the flange 36 of the container body 34 with less effort. It can be released.

Therefore, as locking and unlocking are easily performed even with a small force, excessive force is not applied to the convex protrusion 46 and the flange 36 when locking or releasing, so that the convex protrusion 46 and the flange 36 are deformed or broken. Problems such as this do not occur.

FIG. 5 is an enlarged view of a portion denoted by reference numeral '35' in FIG. 4. Description of the container body 34 will be described with reference to FIGS. 2 and 3.

For reference, the molding of the container main body 34 to be molded in this embodiment is a container body in a semi-finished state in which the shape of the flange 36 and the container main body 34 in which the concave grooves 44 are not formed is not neat. The 34 is molded, and the container main body 34 is divided into parts for molding.

Specifically, the mold includes a first mold 50 for forming a flange upper region a including an opening 16 formed vertically, and a flange lower region b disposed outside the first mold 50. And a second mold 52 for molding the mold, and a third mold 54 disposed below the second mold 52 to mold the container body lower region c below the flange 36.

When the container body 34 in the semi-finished state is transferred to the molding apparatus as described above, the first mold 50 reciprocating vertically is in close contact with the opening 16 and the flange upper region a, and then horizontally. The second and third moving molds 52 and 54 move together while being in close contact with the flange lower region b and the container body lower region c to apply pressure to perform molding.

At this time, the convex protrusions 58 are formed to protrude downward in the molding part 56 of the first mold 50 corresponding to the point S where the opening 16 and the root of the flange 36 meet each other. Therefore, the concave groove 44 formed by the convex protrusions 58 is formed on the upper surface of the flange 36 during molding.
