BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is an overall cross-sectional view of one embodiment of a foaming resin lipping-preventing fabric and a food container using the same according to the present invention.

The present invention relates to a foamed resin lip cleansing fabric, which is a fabric 10 made of a foamed resin, in which a coating layer 11 is formed on one side of the fabric 10, (12) is formed.

That is, a method of laminating the transparent film 12 on one side of the fabric 10, which forms the inside of the container, is adopted when producing a fabric for food container production.

A food container, more specifically, a disposable instant noodle (cup noodle) container, a lunch box container or the like, is manufactured by manufacturing a foamed resin cloth and punching the container to prepare a container body and sealing the sealing cap on the opened upper surface.

Polypropylene (PP), polystyrene paper (PSP), high impact polystyrene (HIPS), etc., or any two or more of them may be used as the foaming resin raw material for the fabric Or may be a foamed resin in a mixed or laminated form, and preferably a raw material based on polystyrene paper (PSP) can be used.

The fabric 10 and the transparent film 12 are made of polystyrene (PS).

The foamed resin fabric of the present invention is characterized in that a coating layer is formed on one surface corresponding to the outer surface of the container in order to improve the aesthetics and easiness of storage and transportation and on the other surface corresponding to the inner surface of the container, A transparent film may be coated (laminated) to prevent the lip portion corresponding to the rim from being torn.

Referring to FIG. 1, the present invention is a food container 20 made of a foamed resin fabric, which is manufactured using the foamed resin lip cleavage preventing fabric A, To form a side surface.

Specifically, the transparent film 12 coated on the other surface of the fabric 10 may be coated on the whole other surface of the raw cloth, or may be coated only on a part of the surface including the lip corresponding to the lip when formed into the container 20 have.

In this case, a transparent film coating layer is further added to the inner side of the container in comparison with the conventional fabric, but the thickness of the basic fabric can be reduced to suppress the increase in the total weight or cost, To prevent the release of harmful substances and to minimize food residue on the inner surface of the container after tasting.

FIG. 2 is a process drawing of the whole apparatus for the method of manufacturing the foamed resin licking-off fabric according to the present invention.

As described above, the coating layer 11 is formed on one side of the fabric 10 and the transparent film 12 is coated on the other side of the fabric corresponding to the inner region when fabricating the food container.

Specifically, in the manufacturing method of the fabric 10 made of a foamed resin, a raw fabric pressing step (S10) for pressing the raw fabric 10 supplied with the pressing roller 110; A coating layer forming step (S20) in which the coating roller (120) presses the raw material (10) supplied and coated with the raw material for forming the coating layer (11) on one side of the raw cloth (10); And a transparent film forming step (S30) in which the heating roller (130) presses the raw material (10) supplied with and applied with the raw material constituting the transparent film (12) on the other side of the raw material (10).

In addition, as described above, the process of coating the coating layer and the transparent film on the fabric can be classified into an in-line type of roll-to-roll and an outline type, and can be suitably selected depending on the situation.

The former is a method in which the coating layer 11 and the transparent film 12 are formed in one continuous process with respect to one surface and the other surface of the raw fabric. The latter is a process in which a coating layer is first formed on one surface of the fabric, And a second coating operation for forming a transparent film on the other surface.

The latter outline method has a drawback in that it takes more time and cost, but the coating is more precisely formed through aging time, which is advantageous in terms of quality. In contrast to the inline type of electron, However, the quality is somewhat less accurate.

In the case of the in-line type, in the coating layer forming step S20, the raw material 10 having passed through the coating roller 120 is continuously processed in a transparent film forming step S30. In the transparent film forming step S30, The hooking roller 141 is provided with a step S31 of feeding the transparent film 12 so as to face the other surface of the fabric 10; The at least one horizontal roller 142 stretching and planarizing the coating layer 11 formed on the fabric 10 and the fabric 10 with the transparent film 12 abutted thereto (S32); At least one of the at least one banana roller 143 may be formed by uniformly stretching the transparent film 12 against the other surface of the fabric 10 (S33); And the upper heating roller 130 may pressurize and adhere the transparent film 12 to the other side of the fabric 10 supported by the lower general roller 131 (S34).

Figs. 3 to 4 are conceptual diagrams showing inline type embodiments, and Fig. 5 is a flowchart thereof.

Specifically, in the case of the in-line type, the raw material 10 is supplied and is firstly pressed by the pressing roller, and raw material for forming a coating layer is supplied to one side of the raw cloth through the T-die equipment T, The raw material for forming the transparent film 12 is secondarily supplied to the other side of the fabric 10 and is pressed in a state of being applied through the heating roller 130 Method.

As the raw material of the transparent film 12, various polymeric resin materials may be employed, but it is preferable to use a transparent film made of polystyrene paper (PSP) as the same material as the foamed resin raw material.

Further, the fabric 10 having passed through the transparent film forming step S30 may be wrapped around the winder 200 and have a second aging step S40 for at least three days.

Meanwhile, in the coating layer forming step (S20), the coating temperature is controlled to 200 to 260 DEG C, and the thickness of the coating layer can be controlled to 80 to 250 mu m. This is preferable in terms of the function of the coating layer 11 and prevention of the rise of the entire fabric thickness.

Further, in the transparent film forming step (S30), the bonding temperature of the transparent film is controlled to 120 to 160 DEG C, and the thickness of the transparent film can be controlled to 15 to 35 mu m. This is preferable in view of the function of the transparent film 12 and prevention of the rise of the entire fabric thickness. Table 1 below shows the results of experiments on the degree of slitting of the lip according to the thickness of the transparent film and the occurrence of scrap due to the increase in thickness.

Table 1. Experimental results according to thickness of transparent film Thickness (㎛) Degree of lips Whether scrap is generated due to the increase in thickness 5 Torn Almost none 10 Torn none 15 Good none 20 Good none 25 Good none 30 Good none 35 Good none 40 Good Occurrence of scrap 45 Good Occurrence of scrap

Referring to this, it can be seen that the thickness of the transparent film 12 is at least 15 μm or more, and the degree of scraping of the lip is good.

On the other hand, in the case of the outline type, in the coating layer forming step S20, the fabric 10 having passed through the coating roller 120 is wound by the winder 200 and aged for at least three days (S21 And the aging of the raw fabric 10 is released again and the process proceeds to a transparent film forming step S30 wherein the transparent film forming step S30 is performed such that the peeling hanger roller 141 is placed on the other side of the fabric 10 (S31) of supplying the transparent film (12) so as to face each other; The at least one horizontal roller 142 stretching and planarizing the coating layer 11 formed on the fabric 10 and the fabric 10 with the transparent film 12 abutted thereto (S32); At least one of the at least one banana roller 143 may be formed by uniformly stretching the transparent film 12 against the other surface of the fabric 10 (S33); And the upper heating roller 130 may include a step S34 of pressing and bonding the transparent film 12 to the other side of the fabric 10 supported by the lower general rollers 131. [

6 is a conceptual diagram showing an outline type embodiment of the present invention. Specifically, referring to FIG. 6A, a raw material 10 is supplied and pressed primarily by a pressing roller 110, and then a raw material for forming a coating layer is formed on one surface of a raw fabric through a T- And the coating material is applied by the coating roller so that the coating layer forming process is completed first. The coating temperature and thickness are as described above.

After a period of at least 3 days of aging, a secondary coating (transparent film forming) process is performed as shown in FIG. 6 (b). As described above, the transparent film is secondarily formed on the other side of the fabric The raw material is supplied and pressurized through the heating roller 130. After the secondary coating process, it is preferable that the raw material is aged for about 3 to 15 days.

In the above manner, a food container such as an instant noodle (cup noodle) container or a lunch box container is manufactured using an improved foamed resin fabric (A) having a transparent film formed on the other side of the coating layer on one side, The other surface portion formed with the transparent film forms the inner surface of the container and the one surface portion formed with the coating layer forms the outer surface of the container. Specifically, the upper heater is controlled in a temperature range of 270 to 330 ° C., the lower heater is controlled in a temperature range of 190 to 250 ° C., and the molding time is controlled to about 5 to 7 seconds.
