Description

[0002] Refrigerated packaging for meat and fish [0003]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a container for refrigerated meat and shellfish, and more particularly to a container for refrigerated meat and fish and shellfish which can maintain meat or fish or shellfish being packaged for a long time in a distribution process.

Recently, large retailers such as home shopping and department store store meat, fish and shellfish such as beef, pork, etc. purchased by consumers into packaging containers and deliver them to consumers. Usually, the packaging container is formed by thermally adhering a film to a plastic or plastic container formed by a molding frame. Prior art relating to such a packaging container is disclosed in Utility Model Registration No. 20-0357851.

At this time, since the packaging container containing the packaging object is consumed for a certain period until it is delivered to the consumer, the packaging object should not be shrouded in the distribution process. For this purpose, the packaging container was placed in a styrofoam box having good heat insulation, and the dry ice was distributed in a styrofoam box packed together.

However, since the styrofoam box used for refrigerated distribution is bulky, it is not possible to mount a large amount in the vehicle at the time of distribution, which causes a lot of transportation costs, which has led to an increase in the price of the purchased product.

Also, the styrofoam box had to be disposed of after removing the packaging container, which was a cause of environmental pollution.

The present invention has been made in order to solve the above problems, and it is an object of the present invention to provide a styrofoam box which is capable of refrigerated distribution without employing a styrofoam box, thereby reducing transportation costs and further preventing generation of styrofoam waste The present invention provides a container for refrigerated meats and fish and shellfish.

Another object of the present invention is to provide a refrigerated packaging container for meat and shellfish, which can maintain long-time refrigerated state and enable long-distance delivery.

In order to achieve the above object, a container for refrigerated packaging of meat and shellfish according to the present invention is a container for packaging objects P such as meat or fishery products, and includes a container 11 having a frame 11 bent at right angles along the edge thereof, (10); A film (20) thermally adhered to the rim (11) to close the mouth of the container (10); A refrigerating unit 30 installed on an inner wall of the container 10 to receive the dry ice DR; And the refrigerating unit 30 is disposed in the container 10 so that the carbon dioxide sublimated in the dry ice DR is discharged so that the air outside the container 10 flows into the container 10 Way check valve (40) to prevent the flow of the fluid.

In the present invention, the carbon dioxide sublimated in the dry ice (DR) formed on the inner wall and bottom of the container (10) is supplied to the one way check valve Way check valve 40 in order to allow the refrigerant to flow to the one-way check valve 40. The one-

In the present invention, a pair of guide fitting grooves 15 are formed on the inner side wall of one side of the container 10; The refrigerating unit 30 includes a main compartment 31 in which the dry ice DR is received and a guide fitting blade 35 extending from a side edge of the sub compartment 31 and interposed in the guide fitting groove 15 ). At this time, the main compartment 31 includes an inner sub-compartment 32 in which the dry mixer DR is received, and an outer sub-compartment 33 spaced apart from the outer peripheral surface of the inner sub-compartment 32.

As shown in the figure, the meat and shellfish refrigerated packaging container according to the present invention is a container for packaging objects P such as meat or seafood, and includes a container 10 having a frame 11 bent at right angles along the edge thereof, ; A film (20) thermally adhered to the rim (11) to close the mouth of the container (10); A refrigerator (30) installed on an inner wall of the container (10) and containing the dry ice (DR); The container 10 is formed in a container 10 opposed to the refrigerating unit 30 so that the carbon dioxide sublimated by the dry ice DR is discharged and the air outside the container 10 is prevented from flowing into the container 10. [ And a way check valve (40).

The container 10 is packed with a wrapping object P wrapped with a wrapping paper such as vinyl. Such a container 10 is made of a synthetic resin material such as PET, and is molded and formed by a mold.

2 and 3, carbon dioxide sublimated by dry ice (DR), which will be described later, is introduced into the inner wall and bottom of the container 10 through the space between the object P and the container 10, A plurality of cold air flow paths 12 formed in the direction of the one-way check valve 40 are formed so as to flow into the check valve 40. This cold air flow path 12 is realized by forming irregularities having directionality on the inner wall and the bottom when the container 10 is molded.

As shown in FIG. 3, a pair of guide fitting grooves 15 to which the refrigerator 30 is coupled are formed on one inner side wall of the container 10.

The film 20 is made of PP or PE material and is thermally adhered to the rim 11 of the container 10 by high frequency or the like. This film 20 is removed when the object P to be packaged is to be taken out of the container 10.

The refrigeration unit 30 is for keeping the object P packaged in the container 10 in a refrigerated state during the distribution process. 3, the refrigerating unit 30 includes a main compartment 31 in which the dry ice DR is received and a main compartment 31 extending from a side edge of the sub compartment 31, And a guide fitting blade 35 which is inserted into the guide fitting groove 15 formed therein. Accordingly, the refrigerating unit 30 is coupled to the separately formed container 10, and if the object to be packed is to be refrigerated for a different period of time, the refrigerating unit 30 can be replaced with a different sized refrigerating unit.

For reference, the container 10 is formed by pouring synthetic resin into a plurality of pairs of forming molds having concave and convex portions, and then joining the forming molds. Therefore, the refrigerating portion 30 protruding in the vertical direction from the inner side wall of the container is molded It is realistic and very difficult. Therefore, the refrigeration unit 30 is molded independently of the container 10, and then assembled into the container 10.

As shown in Figs. 3 and 4, the sub-container 31 includes an inner sub-container 32 in which the dryers DR are accommodated, and an inner sub-container 32 which is spaced apart from the outer peripheral surface of the inner sub- And an outer sub-compartment (33) formed with a guide fitting blade (35). At this time, a spacing connection end 31a is formed between the inner sub-container 32 and the outer sub-container 33 so that the inner sub-container 32 and the outer sub-container 33 can be spaced apart from each other.

A plurality of discharge holes 32a and 33a through which the carbon dioxide of the dry ice to be sublimated is discharged are formed in front of the inner subchamber 32 and the outer subchamber 33, respectively. The discharge holes 32a and 33a open toward the object P and the carbon dioxide sublimated in the dry ice DR is discharged toward the object P to be packaged.

Since the inner sub rack 32 is embedded in the outer side of the outer sub rack 33 so that the inner sub rack 32 containing the dry ice DR is in direct contact with the packaged object P Can be prevented. This is technically meaningful and will be described as follows.

Since the dry ice DR is in a cryogenic temperature of minus 78 캜, the temperature of the sidewall of the inner sub rack 32 containing the dry ice DR also maintains a very low temperature of minus several tens of degrees. Therefore, the tissue of the package object P may be damaged if the inner sub-package 32 is brought into direct contact with the object P to be wrapped.

Also, when the inner sub-compartment 32 at a cryogenic temperature of minus several tens of degrees is brought into close contact with the container 10, the temperature of the sidewall of the container 10 can also be extremely low. In this case, the cold heat of the dry ice (DR) is conducted to the outside, which promotes the sublimation of the dry ice (DR), thereby shortening the refrigerating time. Furthermore, the end user may be burning hands when holding the cold storage container of the present invention by hand.

Also, because the inner sub-container 32 is in a cryogenic condition, it is extremely vulnerable to impact due to the nature of the synthetic resin, and therefore can be easily broken when a weak impact is applied from the outside. In this case, the accommodated dry ice DR may come out of the inner sub box 32 and directly contact the package object P, and thus the structure of the package object P may be damaged.

In order to prevent direct contact of the inner package 32 holding the dry ice of -78 deg. C with the package P or the container 10, the inner package 32 The outer sub-chamber 33 is spaced apart from the outer sub-chamber 33. [ Accordingly, even if the package P is brought into contact with the outer sub box 33 because the outer sub box 33 is not in a cryogenic temperature state, it is possible to prevent the structure of the package object P from being damaged, 32 can be prevented from being conducted to the container 10, so that the refrigerating time can be increased. Further, even if the user holds the container 10 by hand, the user can not be burnt.

On the other hand, the refrigeration unit 30 is positioned to be spaced from the bottom of the container 10 to the upper side, as shown in Fig. Since the carbon dioxide sublimated from the dry ice is heavier than the air, the refrigerating unit 30 is positioned above the bottom of the container 10 so that the carbon dioxide discharged therefrom can be filled in the entire container 10.

The one way check valve (40) So that the carbon dioxide sublimated in the refrigerating unit 30 is discharged from the vessel 10 and outside air is prevented from flowing into the vessel 10 and further the amount of carbon dioxide discharged is minimized to lower the sublimation rate, Increase the time. The one-way check valve 40 includes a valve body 41 which is engaged with the engaging hole 10a on the upper side of the sidewall of the container 10 opposite to the refrigerator 30 and has a stopping protrusion 41a at one end, A check valve 43 selectively engaged with the valve hole 42 in the inside of the valve body 41 and a check valve 43 selectively engaged with the valve hole 42 are provided in the valve body 41 on the side of the stopping jaw 41a, An elastic member 44 for applying elasticity in a direction in which the valve hole 42 closes the valve hole 42 and a sealing 45 opened between the engaging step 41a and the side wall of the container 10. At this time, a hook 41b is formed on the outer circumferential surface of the valve body 41 so that the one-way check valve 40 can be engaged with the coupling hole 10a from the outside of the container 10 in one direction.

By this one-way check valve 40, when carbon dioxide sublimated in the dry ice DR is in a high-pressure state, the carbon dioxide exerts pressure on the check valve 43 to be separated from the valve hole 42, Carbon dioxide is discharged through the valve hole (42). Accordingly, it is possible to prevent the interior of the container 10 from being in a high-pressure state due to the sublimation of carbon dioxide, thereby preventing the film 20 covered with the container from being damaged.

On the other hand, the one-way check valve 40 controls the discharge of the dry ice carbon dioxide to such an extent that the film 20 is not broken by the pressure in the container 10, so that the container 10 is kept at a higher pressure than the outside. Accordingly, it is possible to delay the sublimation of carbon dioxide from the implemented dry ice by pressurizing the carbon dioxide, and as a result, the refrigeration time can be increased.

As described above, according to the refrigerated packaging container of the present invention, it is possible to refrigerate the object P to be instantly shrunk at room temperature, such as meat or seafood, by adopting the refrigerator 30 in which the dry ice is received, It is possible to reduce the transportation cost by not employing the styrofoam box, and further, the consumption of the styrofoam box which causes the environmental pollution can be reduced.

In addition, the one-way check valve 40 minimizes the amount of carbon dioxide that is sublimated from the dry ice, thereby keeping the interior of the container 10 at a high pressure state, thereby extending the sublimation time, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
