Abstract

The present invention relates to a hermetically sealed container for storing foodstuffs in a multi-tiered manner in a refrigerator or the like, and more particularly to a hermetically sealed container in which a container and a lid are tightly coupled to each other It is used for multi-stage separation lamination so that it can be used hygienically.

Description

[0001] The present invention relates to an airtight container for preventing foreign matter from being trapped and capable of multi-

The hermetically sealed container for storing food at present is composed of a container body having an upper opening formed with an inner space formed therein, and a lid having a packing fitted thereto by a locking wing folded over the container body.

The hermetically sealed containers are generally injection-molded by plastic. The hermetically sealed container has an upper rim protruding from an upper rim and a flange extending outwardly from a lower rim directly below the upper rim. The structure of the lid to be coupled with the container housing is such that a protruding upper edge of the container housing forms an inner grove for inserting the inner container, a packing which is detachably mounted on the inner grove and holds elastic force, A plurality of folding locking blades are provided on the edge of the lid so as to be pressed against the upper edge of the container enclosure so that the locking blades are pressed against the locking means formed on the flange of the container housing while pressing the locking blades so that the packing is pressed, It will be done.

However, the disadvantage of this structure is that the foreign matter is buried in the packing which is detachably mounted on the inner groove of the lid, or the foreign matter is caught in the gap formed by the packing which is elastically acted on the inner grove and the packing is tightly fitted in the inner groove It is difficult to remove the packing easily and it is not hygienic because it can not be easily cleaned in the state of being pinched and foreign material is caught between the flange spreading at almost right angles to the lower edge of the upper edge of the container body, This is because the foreign substances in these parts are trapped and are thus unsanitary by the propagation of various bacteria.

In addition, when the lock wing is folded at the rim of the lid, only the locking wing protrudes downward from the rim of the lid. Therefore, when the lock wing is engaged with the container housing, It is inconvenient to use the city.

In addition, in order to remove foreign matter trapped between the packs detachably mounted on the lid, a packing is formed in the lid by inserting through the through hole the packing so as to penetrate through the inner grooves and the upper surface of the lid, It has been proposed to provide it integrally and not to be arbitrarily separated.

However, such a packing structure of the lid can solve the problem that the foreign matter is trapped between the conventional lid and the detachable packing, but it is suitable for the structure having the upper rim and the flange spreading right downward in such a structure, It is not possible to solve the problem that the foreign matter trapped in the boundary of the upper end of the housing and the flange is caught in the housing and that the locking wing is projected downward from the rim of the lid. I could not solve it.

In addition, the lid is integrally formed by double injection molding by the insert method, and the lid is usually formed of a PE material having a soft characteristic. The packing is made of a flexible (usually elastomer) material having good adhesive strength and excellent elasticity In this case, since the molding conditions of the lid and the packing are different from each other, the lid is deformed due to twisting or the like.

In recent years, such closed containers are usually stored in a refrigerator or the like. In such a case, they are stored in a stacked state in a multi-stage storage space of the refrigerator. If the storage containers can not be fixed in a stacked state, an external force In this case, the laminates are stacked in a multi-layered structure in order to prevent them from falling off. In such a multi-layer lamination fixture, As a result of this cold air shrinkage, arbitrary separation occurs, or when the container is shrunk due to shrinkage, the lid is separated and the contents are poured out.

Accordingly, in the present invention, it is possible to maintain tight airtightness by use of the locking wing on the container housing made up only of the upper rim, and the locking wing of the lid is not protruded from the rim of the lid, And. In addition, it is possible to prevent the foreign matter from being caught in the packing, to maintain tight airtightness, and to stack and separate the sealed container in multiple stages.

To this end, in the present invention, in forming the packing inner grove for mounting the packing on the lid, the outer wall extended from each corner is formed downward to the outer wall of the packing inner grove, and the locking wing is folded between the extended outer walls .

Further, in order to allow the flow of the molding material to flow through each corner of the lid during insert injection molding in the packing inner grove, the size of the through hole is made to be larger than the through hole of the other part (straight portion) will be.

In addition, the insert-molding packing is sufficiently filled in the packing inner groove so that the elastic force by the pressure is excellent and the airtightness is maintained.

Further, the packing to be insert-molded in the packing inner grove has a thick wall thickness at a portion where the inner wall of the upper end of the container housing is closely contacted to form an inner groove so as to have a close contact force with the upper surface of the container housing.

In addition, the laminated inner grooves are formed on the upper surface of the lid so that multi-layer lamination is possible. The laminated inner grooves are formed by the curved surface forming the packing inner grooves on which the packing is mounted.

In addition, on the upper surface of the rectangular lid, partition lines are formed so as to enable stacking of hermetically sealed containers of different sizes when stacking multi-stages, and such twisting of the rectangular lid is also prevented by such division lines.

In addition, since the pressure surface is formed so as to protrude from the laminate inner hut with the packing which is not changed by the temperature change so that the stacked state of the multi-layer stacking can be easily separated from the fixed state, So that the clamping force of the laminated state is maintained.

Further, when the protruding pressing surface is formed, the pressing surface is extended to the bottom surface of the laminated inner grooves, thereby preventing the pressing surface from being separated when the pressing surface is repeated by the pressure to be pressed It is.

In addition, when the pressing surface by the packing is protruded, the inner surface of the lid is formed so as to have a large elastic force so that the pressing surface protruded at the time of pressurization does not generate any thrust.

In addition, since the upper end of the container body is formed with a step to form the inner core at the portion where the packing is closely attached, a space is formed when the inner core is in close contact with the packing, .

Therefore, according to the present invention, since the packing is filled in the packing inner grove of the lid, the packing can be kept downward without spreading while maintaining a great elastic force by various forms of the upper frame, Since the pressing surface is formed to protrude from one side wall of the laminated inner groove formed on the upper surface of the lid when the insert is to be formed, the fixed holding in a state where the lower edge of the container housing is laminated in multiple stages is made to be resistant, The lock wing is positioned between the extended outer wall formed at each corner of the lid so as to prevent the locking wing from being protruded. , And a partition line is formed on the upper surface of the lid having a rectangular shape The thickness of a portion of the upper end of the container housing which is extended from the inner wall of the container housing when the inner groove is formed in the packing in close contact with the upper end of the container housing, It is possible to maintain tight airtightness by being formed at a thick position.

In the present invention, when the packing inner grove 12 is formed at a predetermined depth in the rim of the lid 10, the outer wall 19 extending at each corner is formed to extend downward to the outer wall of the packing inner grove 12, Between the extended outer wall (19), a locking blade (14) which can be folded is formed.

Therefore, the locking blade 14 does not protrude downward only at the edge of the lid 10 as in the conventional art, so that a new design can be provided without causing a latching.

At this time, in order to minimize the protrusion of the locking vane 14 forward from the extended outer wall 19 in the locked state when the locking vane 14 is folded, the stepped surface 16 is formed at the edge of the lid.

As shown in FIGS. 4 and 9, when the packing 30 is inserted and molded in the packing inner grove 12, the curved portions of the lid 10 are bent at the corners of the curved portion The size of the through hole 13 is formed to be larger than that of the through hole 13a formed in the other portion (a portion formed by a straight line), so that the moldability of the injection is improved.

The packing 30 to be insert molded in the present invention is sufficiently filled in the packing inner grove 12 having a predetermined depth as shown in Fig. 1, so that the elastic force by the pressing of the upper end frame 22 of the container housing 20 It works well, so it keeps the confidentiality excellent.

5 shows another embodiment of the packing according to which the exposed surface 31 of the packing 30 to be insert-molded in the packing inner grove 12 is provided with an inner surface 31 corresponding to the curved shape of the upper frame 22, The grooves 34 are formed so as to allow close contact with the curved shape of the upper frame 22. [

As shown in FIG. 3, the inner groove 34 formed in the packing 30 is extended to a portion where the inner wall 25, which is formed by extending from the upper end frame 22 of the container housing 20, It is possible to maintain a strong and close adhesion with the upper edge 22 of the container housing 20 by forming a thicker thickness.

8, the lid 10 is provided with a laminated inner groove 18 on the upper surface of the lid 10 so that the lid 10 can be multi-stacked and easily stacked, 18 allow the packing inner grove 12 and the laminated inner grove 18 to be simultaneously realized by the curved surface 17 forming the packing inner grove 12 on which the packing 30 is mounted.

10, a partition line 15 may be formed on the upper surface of the lid 10 so as to enable stacking of closed containers of different sizes (shapes in which rectangles and rectangles are equally divided) in the multi-stage stacking, (15) to prevent twisting of the rectangular lid (10) as well as multi-layer lamination of different sizes.

7 shows one embodiment in which the pressing surface is formed. In this embodiment, the one side wall 18a of the laminated inner grooved structure 18 is fixed to the multi-stage laminate and the fixed holding in the laminated state, The pressing face 32 is pressed against the lower frame 24 of the container housing 20 by protruding from the packing 30 while extending from the portion where the through hole 13a is formed, So that the adhesive force in the laminated state is maintained.

For this purpose, the inner surface of the lower frame 24 is generally smaller than the outer surface of the lower frame 24 in a state in which the pressing surface 32 is protruded, so that the pressing surface 32 is pressed and fixed tightly while being pressed.

In addition, when the protruding pressing surface 32 is formed, the pressing surface 32 is formed to extend to the bottom surface 15 of the laminated inner grooves 18, So that the pressing surface 32 is prevented from being separated from the pressing surface 32.

In order to increase the adhesion force when the pressing surface 32 is protruded by the packing 30, in order to increase the thickness of the pressing surface 32, the one side wall 18a of the laminated inner grove 18 of the lid ) Is formed to form the inner surface 18b.

8, the upper end 22 of the container housing 20 is curved, and at the portion where the inner groove 34 of the packing 30 is in close contact with the upper end frame 22, The inner grooves 34 of the packing 30 by the inner grooves 25 come into close contact with each other to form the space 1 and the airtightness is maintained by the pressure difference between the inside and the outside of the space 1 To make it better.

6 shows a state in which the space 1 is formed in the inner rib 25 formed in the upper end frame 22 of the container housing 20 while the exposed surface 31 of the packing 30 is flat, It is possible to maintain the airtightness because of the difference in pressure between the outside and the outside. Thus, even when the packing is made more flexible, the airtightness can be improved by increasing the friction area.

In the present invention, the packing 30 is made of elastomeric material, but such material does not limit the object of the present invention, and various materials having such properties can be used.

In the present invention, the packing 30 is filled in the packing inner grove 12 of the lid 10, and the lid 10 is turned upside down while forming a contact protrusion 16 that extends to the upper surface 11 and protrudes from the upper surface. The occurrence of noise can be eliminated even when it is placed on the bottom surface of the housing, and the generation of residual gas on the upper surface can be suppressed.

The packing 30 may include an extension portion extending from the packing inner grove 12 to the curved surface 17 forming the packing inner grove 12 or the laminated inner grove 18 for more complete airtightness of the packing 30. [ And the extended portion 36 of the packing 30 is closely attached to the inner wall 25 of the container housing 20 so that the packing 30 can be more easily damaged and hermetically maintained.
