Description

An absorption pad used in absorbing liquid of food}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an absorbent pad (hereinafter referred to as an "absorbent pad for absorbing food liquid") which is disposed and used between food and a food container during food packaging in order to absorb and store liquid discharged from the food.

More specifically, the present invention relates to an absorbent pad for absorbing food liquids, which can quickly absorb liquids discharged from foods, and has excellent antibacterial properties, so that foods can be stored in a fresh state for a long time.

In general, foods such as meat, fish, vegetables, and fruits are destroyed when the cells are destroyed, the fluid inside and outside the cell flows out to reduce the freshness of the food. When the freshness of the food is reduced, the water retention capacity of the food is reduced, and more liquid (exudate) flows out of the food, further accelerating food self-degradation, bacterial growth and discoloration.

In order to maintain the freshness of food, a method of separating the food and the spilled liquid by absorbing the liquid spilled from the food using the absorption pad is widely used.

When paper or sponge is used as the absorbent pad, the food and the liquid spilled from the food appear to be separated from each other, but in fact, the freshness of the food cannot be maintained because they are in contact with each other.

Recently, an absorbent pad composed of an upper sheet, a lower sheet, and an absorbent material layer disposed therebetween has been proposed and widely used in order to further improve the freshness of food by keeping food and the liquid spilled from the food separated from each other. .

As a specific conventional absorbent pad for absorbing food liquids, Korean Patent Laid-Open Publication No. 1992-2324 proposes an absorbent pad in which a powdered or granular edible sugar is located between a semipermeable membrane and a water absorbent porous sheet. The present invention proposes an absorbent pad in which absorbent materials such as pulp and / or carboxymethylcellulose are arranged between the upper sheet and the lower sheet, and Korean Patent Laid-Open Publication No. 1999-87146 discloses an upper sheet and a lower sheet bonded to form one or more cells. It is proposed an absorbent pad having a sheet, wherein an absorbent is placed in the cell and at least one of the sheets is formed of a liquid impermeable material comprising microperforations.

The conventional absorbent pads have an advantage of absorbing and storing the liquid discharged from the food in a state in which a powdery or particulate absorbent material (absorbent resin) is disposed between the upper sheet and the lower sheet, but separated from the food, but lacks antimicrobial properties. Therefore, a problem that the food stored in the storage for a long time can be used, the liquid can not be quickly absorbed liquid, that is, the absorption rate is low, the freshness of the food is also stored.

An object of the present invention is to provide an absorbent pad for absorbing food liquid with excellent antimicrobial and liquid absorption speed in order to solve such a problem.

In the present invention, the non-woven fabrics 11 and 31 containing the antimicrobial material are used alone in each of the upper sheet 10 and the lower sheet 30, or the nonwoven fabrics 11 and 31 and the tissue layers 12 and 32 are laminated. By using the laminate, it is to provide an absorption pad for absorbing food liquids having excellent antibacterial properties and absorption speed.

Absorption pad for food liquid absorption of the present invention for achieving the above problems is composed of the upper sheet 10, the lower sheet 30 and the absorbent material layer 20 disposed therebetween to the liquid flowing out of the food In the absorbent pad for absorbing and storing, the upper sheet 10 and the lower sheet 30 are formed of the nonwoven fabrics 11 and 31 alone or the nonwoven fabrics 11 and 31 and the tissue layers 12 and 32 containing the antimicrobial substance. Laminated two-layer laminate, and the absorbent material layer 20 is selected from pulp 21, thermally active fibers 22, absorbent short fibers 23, and powder or granular absorbent resins 24. It is characterized by consisting of the above absorbent materials.

The upper sheet 10 is positioned directly under the food when in use, so that the upper sheet 10 is in direct contact with the food, and the lower sheet 30 is in contact with the bottom of the food container. The upper sheet 10 may be formed of one layer of the nonwoven fabric 11 containing the antimicrobial material, or may be formed of two layers of the nonwoven fabric 11 and the tissue 12 containing the antimicrobial material.

As shown in FIG. 1, the upper sheet 10 is a two-layer structure in which a nonwoven fabric 11 containing an antimicrobial material and a tissue 12 arranged below are stacked. The absorbent material in the absorbent material layer 20 is pulled out toward the food. It is more desirable to prevent exit.

On the other hand, the lower sheet 30 may be formed of only one layer of the nonwoven fabric 31 containing the antimicrobial material, or may be formed of two layers in which the nonwoven fabric 31 and the tissue 32 are laminated. As shown in FIG. 1, the lower sheet 30 has a two-layer structure in which the nonwoven fabric 31 and the tissues 32 arranged thereunder are laminated to prevent the absorbent material in the absorbent material layer 20 from escaping to the outside. More preferred.
