Description

Eco-friendly packing container {Eco-friendly packing container}

The present invention relates to an eco-friendly packaging container that can be used without using an absorbent pad, and more particularly, to an eco-friendly packaging container that can be used without using an absorbent pad by providing a groove on the bottom of the container to store moisture discharged from food. it's about

In general, foods such as meat and fish are perishable foods, and when the cells are destroyed, moisture inside and outside the cells flows out to reduce the freshness of the food. This loss of freshness decreases the water holding capacity of food and increases the amount of exudate, so that food self-decomposition, bacterial growth, lipid oxidation, and discoloration of food accelerate the quality deterioration.

In order to solve this problem, a packaging container 1 having an absorbent pad 10 as shown in FIG. 1 has been developed. That is, by placing the absorbent pad 10 between the packaging container 1 and the food, it absorbs moisture contained in the food and maintains the freshness of the food.

However, once these absorbent pads are used, they are difficult to reuse and cause environmental pollution, and the unit price is increased compared to food packaging using only containers, so the cost burden on sellers is increasing.

In addition, even if the moisture contained in the food is removed using the absorbent pad, there is a problem in that the lower part of the food spoils faster than the upper part because the water absorbed in the absorbent pad directly contacts the lower part of the food.

Referring to FIGS. 2 to 5 , the eco-friendly packaging container 100 may include a body portion 110 having a storage space S capable of storing food therein. Although not shown, the storage space (S) of the body portion 110 may be sealed by a cover portion provided separately. The cover portion may be injection molded and detachably provided to the body portion 110 or may be provided in the form of a film and thermally bonded to the upper portion of the body portion 110 .

A bottom surface 111 of the body part 110 may be provided with a plurality of grooves 112 capable of accommodating moisture contained in the food (F). In this way, as the plurality of grooves 112 are provided on the bottom surface 111 of the body portion 110, when food (F) containing moisture such as meat or fish is stored in the storage space (S), moisture It can be stored in the groove part 112 without pooling in the body part 110 . Accordingly, without providing a separate absorbent pad between the bottom surface 111 of the body 110 and the food F, moisture discharged to the surface of the food F is sufficiently removed by storing it in the groove 112. And since the removed moisture does not directly contact the food F, spoilage of the food F due to the removed moisture can be minimized.

For example, the grooves 112 formed in the body portion 110 may be provided in a “Y” shape, and the grooves 112 located in odd-numbered rows and the grooves 112 located in even-numbered rows are directed in opposite directions to each other. can be placed as As shown in FIG. 2, when the Y-shaped structures are arranged in opposite directions, the grooves 112 having a larger area per unit area are formed because there are more overlapping parts than circular or other shapes. You will be able to do it.

The edge of the bottom surface 111 protrudes outward to form a stepped 113, and a circular groove 113a may be provided at the inner edge of the bottom surface 111 by the stepped 113. In this way, as the stepped 113 is formed at the edge of the bottom surface 111, contamination of the bottom surface 111 can be prevented when the packaging container 100 is stored in a refrigerator or storage room. In addition, since the circular groove 113a is provided at the inner edge of the bottom surface 111 by the step 113, more moisture discharged from the food F can be stored through the circular groove 113a. Here, the height of the circular groove portion 113a may be greater than that of the groove portion 112 .

The body portion 110 may be manufactured by injection molding a transparent or translucent resin material that is recyclable. For example, the body part 110 may be injection molded using a polyolefin resin, and may further include ethylene-propylene-diene-based (EPDM) rubber to improve impact resistance.

Specifically, the polyolefin resin may be any one or two or more selected from the group consisting of a propylene homopolymer, an ethylene-propylene copolymer, and an ethylene-propylene-hexene terpolymer, and preferably an ethylene-propylene copolymer. The ethylene-propylene copolymer may be obtained by randomly polymerizing a main component propylene monomer and some ethylene monomers, and for example, may be obtained by polymerizing 1 to 10% by weight of ethylene monomer and the remaining amount of propylene monomer. In this range, impact resistance and heat resistance may be excellent. As a more specific example, the ethylene-propylene copolymer may have a weight average molecular weight of 80,000 to 500,000 g/mol, more preferably 100,000 to 300,000 g/mol, and a melt index (MI, based on D1238) of 10 to 30 g / 10min and density (based on D1505) of 0.90 to 0.95 g/cm 3 is good for ensuring excellent impact resistance and workability.

The ethylene-propylene-diene-based (EPDM) rubber may be an ethylene-propylene-ethylidenenorbornene rubber. By adding this, a target impact resistance property can be achieved. As a more specific example, the ethylene-propylene-ethylidenorbornene rubber may include 60 to 80% by weight of ethylene monomer, 15 to 30% by weight of propylene monomer, and 3 to 10% by weight of ethylidenenorbornene. When this is added to the polyolefin resin in an appropriate amount, an impact strength of 200 J/m or more can be achieved.

EPDM rubber may be added in an amount of 1 to 10 parts by weight, more preferably 3 to 5 parts by weight, based on 100 parts by weight of the polyolefin resin. This is because the effect of improving impact resistance is excellent in the above range. On the other hand, when EPDM rubber is added in an amount of less than 1 part by weight, the effect of improving impact resistance may not be sufficient, and when added in an amount greater than 10 parts by weight, heat resistance may be deteriorated.

The body part 110 may include antibacterial and antifungal components. For example, the antibacterial and antifungal component may include surface-modified zinc oxide nanoparticles, surface-modified zeolite, surface-modified calcined shell powder, and antifogging agent. That is, the surface-modified zinc oxide nanoparticles, the surface-modified zeolite, the surface-modified calcined shell powder, and the antifogging agent are intended to impart antibacterial and antifungal properties to sanitary airtight containers. All characteristics can be obtained.

The surface-modified zinc oxide nanoparticles, the surface-modified zeolite, and the surface-modified calcined shell powder may be surface-modified using silicone oil. Through this, aggregation between particles is prevented, and even when a small amount of the above component is added, excellent antibacterial and antifungal properties can be secured, and it can be well mixed with polyolefin resin and EPDM rubber.

The anti-fogging agent is intended to prevent water droplets from forming by forming a thin anti-fogging film on the surface of the airtight container, and by adding the anti-fogging agent, it is possible to improve a humid environment in which mold is easily propagated and to maintain the freshness of the contents for a longer period of time. For example, the antifogging agent may be provided with one or two or more selected from the group consisting of sorbitan fatty acid esters, glycerin fatty acid esters, and polyglycerin fatty acid esters.

The antifogging agent may be included in an amount of 0.1 to 10 parts by weight, more preferably 0.5 to 5 parts by weight, based on 100 parts by weight of the polyolefin resin. In this range, the antifogging effect may be excellent. In addition, the body part 110 may further include additives such as a colorant, a heat stabilizer, an antioxidant, and an ultraviolet absorber.

6 is a cross-sectional view of an eco-friendly packaging container according to another embodiment of the present invention. In this embodiment, a description will be made focusing on differences from the previous embodiment.

Referring to FIG. 6 , the eco-friendly packaging container 200 may be provided in a tapered shape in which both sides of the groove 112 narrow from the bottom to the top. Accordingly, even if an impact is applied to the packaging container 200 after packaging of the food product F is completed, water stored in the groove 112 may be prevented from splashing toward the food product F.

As described above, the eco-friendly packaging container 100 is provided with a plurality of grooves 112 on the bottom surface 111 for storing moisture discharged from the food F, so that the food F without using an absorbent pad. ) has the advantage of being able to remove moisture discharged from. That is, when the food (F) is stored in the packaging container (100), moisture discharged from the food (F) is stored in the groove part (112), so that it can be used without an absorbent pad.

In addition, as the absorbent pad, which is difficult to reuse, can be removed, the cost incurred when packaging the food F can be reduced, and the packaging container 100 can be manufactured in a more environmentally friendly way by reducing waste of resources.

In addition, since moisture discharged from the food F is stored in the groove 112 and does not come into direct contact with the food F, spoilage of the food F due to the discharged water can be minimized.

In addition, both sides of the groove 112 are provided in a tapered shape in which the width narrows from the bottom to the top, so that when an impact is applied to the packaging container 200 after the packaging of the food F is completed, the moisture stored in the groove 112 It is possible to prevent splashing to the side of this food item F.

In addition, as the packaging container 100 is manufactured by including antibacterial and antifungal components, there is an advantage in that the storage period of food (F) can be improved.
