Sealed container for food storage {Seal container to keep a food}

The present invention minimizes the coupling part of the hinge formed integrally with the slope of the lid part, and reduces the bending stress, that is, the residual stress of the hinge during use, which is integral with the hinge and has one or more fastening holes. To smooth out the movement of the folding and unfolding, to facilitate the use, and to minimize the coupling portion of the hinge and the lid portion of the locking extension piece to prevent damage to the hinge to extend the service life and at the same time on the top of the container body By forming an extension surface in a state in which at least one fastening protrusion is formed, a separate sealing paper or the like may be coupled to the food storage sealed container so that the contents stored in the container body can be kept fresh separately from the fastening of the lid part. It is about.

In general, the sealed container is formed so as to accommodate food and maintain a sealed state. In order to keep food for a long time, it is often reflected in the refrigerated state, and in particular, the original food such as kimchi can be kept in a delicious state by aging for a certain time in a dedicated refrigerator. In order to prevent leakage, a stackable sealed container is required.

However, such a sealed container has a problem that food smell is severe when stored in the refrigerator because the seams are not temporarily sealed by the weak pressure generated by the organic food or the inorganic breathing. In case of rocking, the contents of food flow out from the non-closed gap, which causes many inconveniences in handling.

The general hermetically sealed container is composed of a container body and a lid and a plurality of fastening protrusions protruding from the top of the container body, bent by a hinge on the lid, more precisely the locking extension piece is allowed to rotate around the hinge It is integrally formed, and the locking extension pieces are formed in the position corresponding to each of the fastening projections fastening holes to be fastened to the fastening projections.

In addition, a recess is formed in the bottom of the lid facing the upper edge of the container body, and a packing is fitted in the recess.

Accordingly, cover the lid on the container body and press the finger and at the same time push the fastening hole formed on the lock extension piece toward the fastening protrusion of the container body, and the fastening protrusions are fastened through the fastening hole, and the upper edge presses the packing. The interior space of the main body is sealed to the outside.

By the way, the sealed container is connected to the hinge is a portion of the lock extension piece is very reduced in thickness, the hinge is bent the lock extension piece a number of times, the bending stress is very vulnerable by repeated acting is very fragile and easily torn and broken when repeated bending However, once a part of the hinge is torn a little, it continues to spread along the hinge line, which significantly reduces the life of the sealed container, which has been pointed out as the biggest problem of consumer complaints. It can not be confirmed in the state, and since the problem is revealed after a certain period of time when the consumer is using the product, it has been pointed out as a big hole in consumer protection.

In order to improve the above problems, look at the claims of the Patent Application No. 2000-40798 dated July 15, 2000 "the plastic four-sealing container for food" [Claim 1. A long container body of a long length; A plurality of locking protrusions protruding from the top of the container body on one side or two on each of the four sides, each of which is formed at least on the long side at intervals; A lid composed of a locking blade portion formed at each position of the locking hole inserted into each of the locking projections against the locking projection, and an upper cover piece which is rotatably connected by the hinge; A packing attached to the upper cover piece of the lid to seal the container body; In a four-sided sealed container for food and plastic material comprising a, the injection hole is formed by providing a melt flow blocking hole between the locking hole formed in the left and right two places of the locking wing portion to form a gorge between the locking hole.

The container according to claim 1, wherein a support ring having a quadrangular ring shape is formed under the container body, and the surface is roughly opaque and opaque to the upper cover surface of the lid to which the support protrusion contacts when stacking a plurality of containers. It is a technical feature of a four-sealing plastic container for food and beverage, characterized by having a corrosion treatment section formed by corrosion.

However, the pre-registered technology has the following problems. Looking at this in detail,

The pre-registered technology has a complicated structure by forming a separate blocking hole between the locking holes and a separate component called the blocking hole, so that the rotation of the locking wing piece may be smooth, but that is, When bending, there is a problem in that the hinge portion is damaged due to the small area of the joint portion of the hinge and the lid of the locking wing piece.

In addition, the blocking holes are not coupled to the locking projections, so that the blocking holes appear in an empty shape in appearance and thus have a problem such as coarseness.

The present invention is intended to supplement the problems of the general hermetically sealed container, as well as the appearance and other functional problems of the pre-registered technology, that is, to minimize the coupling portion of the hinge formed integrally with the slope of the lid portion. In order to reduce the bending stress of the locking extension piece, that is, the resilience force that is the residual stress of the hinge when in use, by forming cutouts on both sides of the hinges formed between the fastening holes, the folding movements that are repeatedly folded and unfolded are smoothed to facilitate convenience of use. At the same time to prevent damage to the hinge to extend the service life and also, by forming an extended surface in the form of one or more fastening projections formed on the upper surface of the container body by allowing a separate sealing paper and the like to be combined Fresh contents stored in the container body separately from the fastening of the lid portion To provide a sealed container for food storage so you can keep it that objective.
