The present invention relates to a food preservation container for a silicon cover with improved preservation performance, and more particularly to a food preservation container for a silicone cover with improved shelter performance, which is structurally simple due to a silicone cover with elasticity and has improved preservation performance.

The food container may have a separating function for separating into small amounts, a function for movement or a storage function, and may be made into a structure suitable for each use. When the food is stored in the container, it is generally advantageous to have high airtightness because the food is corrupted by the bacteria. However, sealing of the storage container can increase the weight or volume of the entire container while increasing the manufacturing cost. Also, when food is stored in a container, it is necessary to maintain freshness or taste. It is advantageous for the portable storage container to have such a sealing function or a taste holding function.

As a prior art related to a container for improving the storage stability of foods, there is a sealed structure of a food container as disclosed in Utility Model No. 20-1998-028253. In the prior art, a round frame having a diameter capable of allowing the container to enter the inner bottom surface of the lid is projected downward in order to improve the sealing structure of the lid and to prevent the leakage of food, and to increase the freshness and taste of food according to far- And a cap having a plurality of micropores formed thereon is screwed to the round frame so that the far infrared radiation emitting material is charged into the space formed therebetween, And a rubber packing with an outward protrusion formed between the round bottom surface of the container and the inner circumferential surface of the cap.

Another prior art related to food storage containers is Utility Model Registration No. 0211205, 'Food Storage Container'. The prior art aims at providing a container for storing foods and a anti-decay pack for preventing contents stored in a cover covering the container from leaking to the outside. In order to achieve the above object, the prior art is a food storage container comprising a body opened upward to store food therein and a lid capable of covering the body, wherein the container is made of ceramics for removing odor, charcoal, and deodorant Anti-corruption pack is integrally attached to the inside of the lid and is formed, and a plurality of through-holes are formed so that the space in the main body and the anti-corruption pack can communicate with each other.

It is advantageous that the storage container is made of a simple structure so that the storage property is improved. If the structure is complicated, the usability is reduced, and at the same time, the manufacturing cost is increased and the durability is deteriorated. These prior art or known preservation vessels have the disadvantage that additional construction must be made for improved preservation performance.

The present invention has been made to solve the problems of the prior art and has the following purpose.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto. In the following description, components having the same reference numerals in different drawings have similar functions, so that they will not be described repeatedly unless necessary for an understanding of the invention, and the known components will be briefly described or omitted. However, It should not be understood as being excluded from the embodiment of Fig.

1A and 1B show an embodiment of a storage container according to the present invention.

1A and 1B, a food storage container for a silicon lid according to the present invention comprises a receiving body 11 made of synthetic resin; An enclosing rim 12 formed on an upper portion of the receiving body 11; And a stretchable rim 21 extending downward from an edge of the stretchable and contractible body 21 and extending to cover a lower portion of the sealing rim 12, The extensible frame 22 is integrally formed with the elongating and contracting body 21 and is in close contact with the circumferential surface of the receiving body 11 by the expansion and contraction of the elongating and contracting body 21.

The storage container according to the present invention can be used for the purpose of containing any food such as vegetables, fruits, drinks, cooked foods, fish or meat, and is not limited by the kind of food. It can also be used, for example, as a mobile container for outdoor food intake and can be used for food separation or storage. Thus, the preservation container according to the present invention can be used without being limited to the use, the place, or the kind of the food to be stored.

The storage container may include a body 10 in which contents are accommodated and a lid 20 detachably coupled to the upper side of the body 10 to seal the body 10. The body 10 may be made of a rigid synthetic resin material, and the lid 20 may be made of a material such as a silicone material, a silicone resin, or a silicone rubber having elasticity or elongation.

The receiving body 11 can be formed in various shapes, for example, a shape of a polyhedron or a cylinder having an open top surface. The receiving body 11 may be made of a synthetic resin material having a high hardness while being integrally made, and may be made of a material such as polyurethane, polypropylene, polyacrylic, polystyrene, acrylonitrile-butadiene-styrene resin, PET (polyethylene terephthalate) And may be made of a synthetic resin material having a sufficiently high hardness as compared with the cover 20. [

The sealing rim 12 may be formed on the upper side of the receiving body 11 and the sealing rim 12 may be formed into a shape having a rectangular cross section while protruding outward. Making the sealing rim 12 square is intended to improve the sealing performance when it comes into contact with the inner portion of the lid 20. The sealing rim 12 may be made larger in thickness than the receiving body 11 and may be made to be 2 to 4 times the thickness of the receiving body 11, for example. If necessary, the edge of the closed frame 12 may be curved, but the overall cross-section may be a square, and thus a curved rectangular cross-sectional shape. The sealing rim 12 may be made of the same material as the receiving body 11.

A bottom portion 13 integrally formed by the same material as the receiving body 11 may be formed below the receiving body 11. [ Thus, the body 10 of the storage container can be integrally formed as a whole.

The lid 20 coupled to the upper side of the body 10 may be made of a silicone material having a high elongation or stretchability, for example a shore A according to ASTM D2240 of 20 to 80; A tensile strength according to ASTM D412 of 1.0 to 3.0 N / mm < 2 >; An elongation in accordance with ASTM D412 of 200 to 800%; And a coefficient of linear expansion of 1.0 x 10 < -6 > to 1.0 x 10 < -4 > (K-1). The lid 20 can be made of a material having a large elongation, a large friction coefficient and a large elastic modulus with respect to the body 10. [ Also, the lid 20 can be made of a material whose change in elongation according to temperature is sufficiently smaller than that of the body 10. [ Specifically, the lid 20 can be made of a material such as silicone resin or silicon rubber having a high elongation, and can be made of a material having a sufficiently small change in elongation according to temperature. The sealing performance can be improved by making the lid 20 made of such a material to have different characteristics from the receiving body 11. If the lid 20 is made of a silicone material, the air permeability is increased. To compensate for this, synthetic resins with low air permeability on the cover may be added during the manufacturing process. For example, a synthetic resin material having an air permeability of 0.1 to 20 (g / m 2 24 h) at a thickness of 20 to 50 탆 may be added to the silicon material. The synthetic resin material may be, but not limited to, a synthetic resin such as polyimide, high-density polyethylene or polyvinylidene chloride. The synthetic resin material having a low air permeability may be added in an amount of 3 to 20 wt% of the total weight of the lid 20.

The lid 20 is composed of a plate-shaped stretchable body 21 and a stretchable frame 22 extending in the vertical direction along the rim or edge of the stretchable body 21 and extending to cover the lower portion of the closed rim 12 have. A rim accommodating portion 211 may be formed between the elastic body 21 and the extensible rim 22. The rim receiving portion 211 is for receiving the sealing rim 12 and may extend downward from the rim of the stretchable body 21 to a length equal to or less than the thickness of the sealing rim 12. And the stretching rim 22 may extend downward from the rim receiving portion 211 again. The rim accommodating portion 211 can be formed in an outward convex shape so that the end portion of the rim accommodating portion 211 is located inside the edge of the stretchable body 21. [ At this position, the stretching rim 22 can extend downward. Due to such a structure, the stretching rim 22 can be brought into close contact with the outer surface of the receiving body 11 by elasticity. The rim receiving portion 211 may have an extension length similar to or greater than the extension length of the stretching rim 22. And the stretching rim 22 may be formed to cover the lower portion of the sealing rim 12.

According to the present invention, the body 10 can be sealed by making the lid 20 made of silicone material having a large elongation. In such a structure, it is advantageous that the lid 20 is uniformly expanded and contracted in all directions with respect to the center portion. For this purpose, the central portion of the elastic body 21 may be formed to have a smaller elongation than the other portions. The size of the central portion is not particularly limited and may be, for example, 1/20 to 1/10 of the total area of the stretchable body 21, but is not limited thereto. In order to reduce the elongation of the central portion, the center portion may be formed to have a different thickness, or may be made of a material having a small elongation or a material having a small elongation. The central portion of the elastic body 21 may be formed in a reduced shape or in a circular shape. The central portion of the elongating and contracting body 21 is made to have a small elongation as described above, so that the lid 20 is uniformly expanded and contracted, thereby improving the hermeticity.

The structure of the inner portion of the lid 20 made of such a structure will be described below. Fig. 2 shows an embodiment of a sealing structure applied to a storage container according to the present invention.

Fig. 2 (A) shows an embodiment of the internal structure of the lid 20, and Fig. 2 (B) shows an embodiment of the external structure of the bottom part 13. Fig.

2 (A), the lid 20 may be composed of a rim accommodating portion 211 and a stretching rim 22 in which the sealing rim 12 is received, and the rim accommodating portion 211 and the elastic body 21 may be formed at the interface of the inflow perimeter 222. The inlet perimeter 222 may be formed in a shape corresponding to the sealing rim 12 and may be a rectangular shape with one side open when the sealing rim 12 has a rectangular cross section as described above. It may extend to correspond to the thickness of the sealing frame 12 in a direction perpendicular to the edge of the elastic body 21. And the contraction rim 22 in a curved shape to be recessed inward can be extended. Due to this shape, the end portion of the stretching rim 22 faces outward.

The rim accommodating portion 211 and the extensible rim 22 are formed to be relatively thicker than the extensible body 21 so that the extensibility can be smaller than that of the extensible body 21. [ In addition, the rim accommodating water 211 may have a smaller elongation than the stretching rim 22. Such elongation can be controlled by the thickness. The elongating and contracting body 21 is stretched in a state where the lid 20 is engaged with the body 10 by making the elongation and contraction main body 21 have a smaller elongation rate than the elongation and contraction rim 22, . This can improve the sealing performance and storage function of the storage container. The elongation of different portions of the cover 20 can be variously adjusted and the present invention is not limited to the embodiments shown.

Referring to FIG. 2 (B), a protruding rim 131 may be formed outside the bottom surface 13. The protruding rim 131 is formed to prevent the outer surface of the bottom surface 13 from contacting with the surface of another object.

The storage container according to the present invention may contain various antibacterial or deodorant components. For example, phytoncide-containing zeolite components, antimicrobial silicon or silver nanoparticles may be added during the manufacture of the body 10 or the lid 20. Various antimicrobial or deodorant components may be included in the preservation container according to the invention and the invention is not limited thereby.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention . The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
