Abstract

The present invention relates to a hermetically sealing container adapted to allow hermetically sealed storage of a foodstuff while being stacked in multiple layers in a refrigerator or the like, and, more particularly, the present invention is adapted such that, when the container casing and a lid are tightly coupled in order to maintain air-tightness, foreign matter is prevented from lodging in packing provided in the lid, thereby allowing hygienic use and at the same time facilitating separated stacking in multiple layers.

Description

Airtight container to prevent pinching of foreign substances and stack

The present invention relates to a hermetically sealed container to keep food while being stacked in multiple stages in a refrigerator, etc., especially when the container and the lid are tightly coupled for airtightness, so that foreign substances are not caught in the packing provided in the lid. By making it hygienic, it is easy to separate and stack in multiple stages.

The current container for storing food consists of a lid equipped with a packing coupled by a container wing having an open top and a locking wing folded with the container housing while the inner space is formed.

In addition, such closed containers are usually injection molded of plastic, and the structure of the container housing for airtightness is provided with an upper edge projecting on the upper edge and a flange extending outwards directly below the upper edge, and the flange is provided with a locking means. And, the structure of the lid coupled to the container housing forms an inlet groove frame so that the protruding upper edge of the container body is embedded, the inlet groove frame is detachably mounted and is provided with a packing to retain the elastic force, the packing is The lid is provided with a plurality of folded lock wings at the edge of the container box to press the upper edge of the container box so that the packing is pressurized by pressing the lock wing to engage the locking means formed on the flange of the container box, thereby keeping the packing tight. Will be done.

However, the disadvantage of this structure is that the foreign material is attached to the packing that is detachably mounted on the inner groove of the lid or the foreign matter is caught in the gap between the inner groove and the elastically operated packing, and the packing is tightly sandwiched in the inner groove. It is not easy to remove the packing, and it is not sanitary because it is not easy to clean in the jammed state, and foreign matter is caught between the Hurenji spreading almost perpendicularly under the upper edge of the container enclosure. The foreign material is caught in this part is due to the multiplication of bacteria caused by this is unsanitary.

In addition, the locking blade is folded in the lid of the lid only the locking blade is projected downward from the lid of the lid in combination with the container housing due to the protruding locking wing caused by the occurrence of jams when stored in the refrigerator, etc. It will cause inconvenience to use.

In addition, in order to remove the foreign matter caught between the packing detachably mounted to the lid to form a through-hole through the inner groove of the lid and the upper surface of the packing by insert injection molding through the through-hole packing on the lid It has been proposed to provide one-piece and not to separate arbitrarily.

However, the packing structure of such a lid can solve the problem that foreign matter is caught between the lid and the removable packing, but this structure is suitable for a structure having an open top edge and a flange extending directly below, so that the container It is not possible to eliminate foreign substances caught in the border of the upper edge of the enclosure and Hurenji. Also, it is designed to protrude downward from the edge of the lid. It did not resolve.

In addition, the lid which is formed integrally by the double injection molding by the insert method is usually formed of PE material with soft characteristics. The packing is made of soft (usually elastomer) material with good elasticity and excellent elasticity. In this case, because the molding conditions of the lid and the packing is different, there is a problem that the deformation caused by the twist, etc. in the lid.

Recently, these sealed containers are usually stored in a refrigerator, etc. In this case, they are stored in a stacked state in the storage space of the refrigerator. In the case of not being fixed in the stacked state, external force (insert other containers around In order to prevent it from being passed, it is fixed in a multi-stacked state. This multi-stage stacking is fixed by means of force pinching. Such cold air causes problems such as random separation or shrinkage and tightness while shrinking, causing the contents to be spilled while the lid is separated.

Therefore, in the present invention, it is possible to maintain tight airtightness by using the locking blades in the container box consisting of only the upper border, and also to prevent the locking wing of the lid from protruding from the edge of the lid, thereby improving design and providing convenience of use. And In addition, close packing is prevented from being caught in the packing while the airtight container is stacked and separated in multiple stages.

To this end, in the present invention, in forming a packing inner groove for mounting the packing on the lid, the outer wall of the inner packing of the packing is formed downwardly at each corner, and the locking blade is folded between the extension outer walls. .

In addition, in order to facilitate the flow of moldings at each corner of the lid during insert injection molding in the packing insert groove, the size of the through hole is made larger than the through hole of the other part (straight line part) to improve the formability. will be.

In addition, the insert-molded packing is sufficiently filled in the inner groove of the packing, so that the elastic force due to the pressurization is excellent so that the airtightness is excellent.

In addition, the packing that is insert-molded in the packing inner groove frame is formed by forming a thick thickness of the portion in which the inner wall of the upper frame of the container container is in close contact with the top frame of the container housing to form a close contact with the top frame of the container enclosure.

In addition, the laminated inner grooves are formed on the upper surface of the lid to enable the multi-stage lamination, and the laminated inner grooves are implemented by the curved surface forming the packing inner grooves to which the packing is mounted.

In addition, the upper surface of the rectangular lid is to form a partition line to allow the stacking of the sealed containers of different sizes when stacked in multiple stages, to prevent the twist to the rectangular lid by this partition line.

In addition, by forming a pressing surface protruding from the laminated inner groove with a packing that does not change in temperature to facilitate the fixing of the stacked state and the separation in the fixed state during the multi-stage lamination, the bottom frame of the container housing in which the pressure surface is laminated in multiple stages It is to maintain the tightness of tight lamination while being pressed with.

In addition, in the case of forming the protruding pressing surface, the pressing surface extends to the bottom surface of the laminated interlocking groove to prevent the phenomenon of being separated when the pressing surface is repeatedly pressed by the pressurized pressure when separating in multiple stages of lamination. It is so long.

In addition, in the case of protruding the pressing surface by the packing, the pressing surface protruded during pressing does not cause the rolling and retains a lot of elastic force so as to form the inner surface of the laminated inner groove of the lid.

In addition, by forming the inner bone is formed so that the packing is in close contact with the upper frame of the container enclosure is formed a space when the contact with the packing by the inner bone is kept airtight due to the difference in pressure between the space and the outside Is to be reinforced.

Therefore, in the present invention, the packing is filled in the packing inner groove of the lid, so that the various forms of the upper frame keep a lot of elastic force, but it does not spread and proceeds downward only so that the airtightness by the close adhesion is excellent, and the packing is In the case of insert molding, the pressing surface is formed to protrude on one side wall of the laminated inner groove formed on the upper surface of the lid, so that the lower edge of the container enclosure can be easily maintained in a multi-stacked state. It extends to the bottom of the inlet groove and is not damaged even by repeated stacking of container enclosures, and also prevents the locking wing from protruding by being located between the extension outer walls formed at each corner of the lid. By forming a partition line on the upper surface of the lid made of a rectangular shape Different sizes of sealed containers are to enable multi-stage stacking, and when the inner groove is formed in the packing close to the top frame of the container box, the thickness of the part where the top frame extending from the inner wall of the container box is in close contact with each other By forming in a thickening position, close tightness is possible.
