Abstract

PURPOSE: To make the label of a label applied foamed resin product hard to peel by interposing an aq. soln. between the inner surface of the female mold of a mold and a label to temporarily fix the label to the inner surface of the cavity and subsequently filling prefoamed particles into the cavity to subject the same to foam molding under heating. CONSTITUTION: Water or an aq. soln. is interposed between the inner surface of the cavity 3 of a female mold 1 and a label 11 to temporarily fix the label 11 so as to closely bond the same to the inner surface of the cavity 3 of the female mold 1. The cavity 3 is subsequently filled with prefoamed particles but, since the label 11 is temporarily fixed, the prefoamed particles are prevented from entering the gap between the label 11 and the inner surface of the cavity 3. In this state, the prefoamed particles are subjected to foam molding under heating to produce a label applied foamed resin product wherein the label 11 is bonded to the foamed resin product. By this constitution, air bubbles do not enter the gap between the label and the foamed resin product and no wrinkles are generated in the label and the label is prevented from protruding from the surface of the foamed resin product and becomes hard to peel.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a labeled foamed resin product for use in instant ramen cup containers, beverage cups such as juice and hot coffee, frozen dessert containers and other packaging containers, and a method for producing the same. In particular, the present invention relates to a foamed resin product with a label having a label on the surface of which labels such as letters, patterns and designs are printed in advance, and a method for producing the same.

[0002]

BACKGROUND OF THE INVENTION Foamed bead cups are widely used as containers for instant noodles, cups for beverages such as juice, and the like.

In this expanded bead cup, expandable resin particles (beads), which are generally polystyrene-based resin particles containing a volatile foaming agent such as butane or pentane, are pre-expanded to obtain pre-expanded particles. Is produced by an in-mold bead foaming molding method in which a cavity of a molding die is filled with and heated and foamed by a heating medium such as steam.

Some of such foam bead cups have characters such as a product name and a manufacturer, or other surface designs such as pictures and patterns.

As a method for providing the display on the surface of the foam bead cup, the display content is directly printed on the surface of the foam bead cup by a printing machine, or a label on which the display content is printed in advance is wrapped around the foam bead cup and adhered. A method known as a shrink label method is known, in which a heat-shrinkable film, which is preprinted with display contents, is wrapped around a foamed bead cup and then heat-shrinked to be attached.

[0006]

However, the above-mentioned conventional structure has the following problems.

That is, it is difficult to perform clear printing such as gravure printing or multicolor overlay printing by the method of directly printing on the surface of the foam bead cup. Therefore, there is a problem in that it is almost impossible to display very fine characters and to display by smoothly shifting the gradation change.

In the method of adhering the label on which the display contents are printed in advance to the foam bead cup, since the label portion is protruded from the foam bead cup by the thickness, the feeling of unity is poor and unsightly. Further, if the adhesion between the foam bead cup and the label is insufficient, the label may be peeled off at the stage of distribution or use, which leads to a decrease in commercial value.

In the shrink label method using the heat-shrinkable film, the heat-shrinkable film is merely attached to the cup due to heat shrinkage. Therefore, when the outer peripheral surface of the cup is inclined, the film is removed from the cup. Easy to detach. In addition, if the shrinkage of the heat-shrinkable film is not uniform, the film is deformed, which makes it difficult to read the preprinted display contents, and it is almost impossible to read the display of fine characters. are doing.

Therefore, in order to solve these problems,
In the method for painting a foam-molded container disclosed in Japanese Patent Application Laid-Open No. 4-331132, a tubular printing paper sheet having a printing layer and a heat sealing layer is set in a female cavity. The printing sheet is fixed to the inner surface of the cavity of the female die by deaerating the inside of the cavity through the deaeration passage provided in the female die. Then, the female mold and the male mold are matched with each other, and the foamable resin particles are filled between the paper-made printing sheet and the core of the male mold to perform foam molding. As a result, the heat-sealing layer of the printed sheet is fused to the tubular foam-molded container, so that the tubular foam-molded container can be painted clearly without distortion.

However, according to this method, since the depression of the deaeration passage is attached to the printed sheet on the surface of the molded product, the appearance is bad, and the printed sheet can be brought into close contact with the inner surface of the cavity of the female mold near this passage. In the vicinity of the upper and lower ends of the print sheet, there is a problem that a gap is likely to occur between the print sheet and the inner surface of the cavity. If there is a gap, the expandable resin particles will enter there, so that a good molded container cannot be obtained.

Further, in the above method, since the paper-made printing sheet having the printing layer on the outer side of the core paper is used, the moistureproof property and the gas barrier property are poor. Further, the vapor used in molding the foamed resin product may cause the paper to absorb moisture, resulting in blurry printing. In addition, since the printing layer is provided outside the core paper and the printing layer is in direct contact with the female mold, the printing ink is easily transferred to the female mold by heat. When this transfer occurs, the printing of the foamed resin product becomes thin and print failure occurs. In addition, since the ink transferred to the female mold is retransferred to the surface of the next molded product, printing defects will continuously occur.

Further, since the print sheet needs to be formed into a tubular paper print sheet, the print sheet cannot be used as it is, resulting in many steps and problems.

The present invention solves the above-mentioned problems of the prior art and has a label in which a clear design display in which fine character display and gradation change are smoothly expressed is printed in advance, and the label is deaerated. (EN) Provided are a foamed resin product with a label, which does not have a dent in a passage, and in which a label does not protrude from the surface of the foamed resin product, is beautiful, and is hard to peel off, and a manufacturing method thereof.

[0015]

In order to solve the above-mentioned problems, the label-formed foamed resin product according to the invention of claim 1 has a label comprising a transparent resin layer and a printed layer adhered to the foamed resin product. The printed layer of the label is arranged on the side of the foamed resin product based on the transparent resin layer.

In order to solve the above-mentioned problems, the method for producing a labeled resin foam product according to the invention of claim 2 uses a molding die composed of a male mold and a female mold to produce a labeled resin foam product. In the manufacturing method, water or an aqueous solution is interposed between the inner surface of the cavity of the female mold and the label to temporarily fix the label on the inner surface of the cavity, and then the cavity is filled with pre-expanded particles for heat foam molding. By
It is characterized by producing a labeled foamed resin product in which a label is adhered to a foamed resin product.

[0017]

According to the constitution of claim 1, since the label comprising the transparent resin layer and the printing layer is provided, the moisture-proof property and the gas barrier property are improved as compared with the conventional foamed resin product using the paper printing sheet. An excellent foamed resin product with a label can be obtained. Therefore, it is suitable for food containers and the like. Moreover, since the printing layer is arranged on the side of the foamed resin product, that is, on the inner side with respect to the transparent resin layer, the printing is hard to stain and is beautiful forever. Further, it is possible to easily manufacture a labeled foamed resin product by foaming resin molding.

According to the structure of claim 2, since the label is temporarily fixed by interposing water or an aqueous solution between the inner surface of the cavity of the female mold and the label, the label can be used without using a degassing passage. Can be easily adhered to the inner surface of the cavity of the female mold without any gap, so that the degassing passage is not dented on the label surface. In addition, filling the pre-expanded particles prevents them from getting between the label and the inner surface of the cavity of the female mold. Since the foamed resin product with a label in which the label is adhered to the foamed resin product is manufactured by heat-foam molding in this state, air bubbles do not enter between the label and the foamed resin product, and the label cannot be wrinkled. That is, the surface of the label does not have the depression of the deaeration passage, and the label does not protrude from the surface of the foamed resin product, which is beautiful and hardly peels off. Furthermore, since water or an aqueous solution is used for temporary fixing of the label, there is almost no adverse effect on the foamed resin product portion, and it is not necessary to provide a degassing passage for temporarily fixing the label in the female mold. As a result, it is possible to easily manufacture foamed resin products such as containers with labels printed with fine text display, clear display that smoothly expresses gradation changes, and displays with multi-color overlay printing, etc. without misalignment. You can

EXAMPLES The labeled foamed resin product of the present invention and the method for producing the labeled foamed resin product of the present invention will be described in more detail below with reference to Examples, but the present invention is not limited thereto.

In the method for producing a cup-shaped foamed resin product with a display according to the present embodiment, a fan-shaped label is wound around a pseudo core (pseudo male type) having air holes on the side surface and sucked through the air holes to form the label. A step of closely fixing to the pseudo core,
A state in which water is sprayed on the label that is closely attached to the pseudo core,
Alternatively, the process of inserting the pseudo core into the female mold while water is sprayed on the inner surface of the cavity of the female mold, and the compressed air is jetted from the air hole of the pseudo core to label the pseudo core from the female mold cavity. After transferring to the inner surface and temporarily fixing it to the inner surface of the cavity of the female mold through the water, after removing the pseudo core from the female mold, and fitting the female mold and the molding core mold (male mold) together and clamping the mold The process comprises the steps of manufacturing a foamed resin product by filling the pre-expanded particles and performing heat-foam molding, and at the same time, adhering the label to the foamed resin product.

In the step of closely fixing the above label to the pseudo core, as shown in FIG. 1, a plurality of air holes 10b are formed on the side surface.
A pseudo core 10 for label insertion having ... Is used.
The shape of the air holes 10b may be, for example, an elongated groove shape as shown in FIG. 11A, or a circular shape as shown in FIG.

The pseudo core 10 is made larger than the molding core die. Inside the pseudo core 10, as shown in FIG. 2, an air chamber 10c is provided.
At the bottom of 0, a passage 10a for reducing or increasing the pressure of the air chamber 10c is provided. As a result, when the vacuum valve is opened, the air chamber 10 of the pseudo core 10 is passed through the passage 10a.
c can be decompressed, and the air chamber 10c of the pseudo core 10 can be pressurized through the passage 10a by opening the pressurizing valve. The air holes 10b ... Lead to the air chamber 10c.

As a result, the fan-shaped label 11 on which the predetermined contents such as characters, patterns, and designs are separately printed is wound around the side surface of the pseudo core 10, and the air chamber 10c is heated to a pressure of 700 to 740 mmHg. If you reduce the pressure,
The label 11 can be closely fixed to the side surface of the pseudo core 10. The pressure of the air chamber 10c may be appropriately set according to the thickness (weight) of the label 11.

Then, in order to transfer the label 11 from the pseudo core 10 to the female mold 1, as shown in FIG. 3, the pseudo core 10 is inserted into the female mold 1 and the air chamber 10c is pressurized. As a result, the air jetted from the air holes 10b presses the label 11 against the inner surface of the cavity of the female mold 1.
As a result, the water sprayed on the label 11 spreads on the inner surface of the cavity of the female mold 1 to form an ultrathin film of water. The label 11 is temporarily fixed to the inner surface of the cavity of the female mold 1 by this ultra-thin film of water, as shown in FIG.

In this step, instead of spraying water on the label 11, water may be sprayed on the inner surface of the cavity of the female mold 1.

Further, an aqueous solution can be used instead of water. As the aqueous solution, an aqueous solution of a cold water-soluble material such as dextrin, gum arabic, methyl cellulose, partially saponified polyvinyl alcohol, urea-based initial condensate, and water-soluble phenol resin can be used. In short, any aqueous solution may be used as long as it is highly wettable with respect to the inner surface of the cavity of the label 11 and the female mold 1 and can temporarily fix the label 11 to the inner surface of the cavity of the female die 1.

In the next step of manufacturing a cup-shaped molded product, the pseudo core 10 is extracted from the female mold 1, the female mold 1 and the molding core mold 2 are matched, and the mold is clamped. For this, for example, a press machine for foaming beads is used. For example, as shown in FIG. 5, the press device includes an upper fixed platen 4
And a lower movable platen 5 that moves up and down by a ram 6, a female mold 1 is fixed to a stationary platen 4, and a core mold 2 is fixed to the movable platen 5. When the female die 1 and the core die 2 are clamped, a cup-shaped cavity portion 3 is formed between them.

The female mold 1 has a steam chamber 1a inside, and a charging device (not shown) for charging the raw material into the cavity 3 through the passage 7, a steam and cooling water supply port 1b. , A drain discharge port 1c, and an air supply port (not shown) for transferring the molded product to the core mold 2. Further, the core mold 2 has a steam chamber 2a therein, and a steam and cooling water supply port 2b, a drain discharge port 2c, and a discharge air port (not shown).
Is provided. Further, although not shown, various pressure reducing valves (regulators) such as a filling air valve, a steam valve, a direct heating valve of the cavity portion 3, a drain valve, a cooling water valve, a discharge air valve, a solenoid valve, and the like. It is equipped with a control panel for controlling.

The molded product is, for example, as shown in FIG.
A polystyrene resin particle having a diameter of 0.25 mm and containing a foaming agent is used as a raw material, and this is 12 times in bulk magnification (diameter: 0.5).
7 mm) pre-expanded pre-expanded particles are produced by an in-mold bead foam molding method and have an expansion ratio of 12 times. The upper part has a diameter of 96 mm and the bottom has a diameter of 69 mm.
Height 108 mm, body thickness 3 mm, internal volume 460
It is cc.

As the resin constituting the expandable thermoplastic resin which is a raw material for the expanded bead cup, polystyrene-based resins such as polystyrene, high impact styrene, styrene-maleic anhydride copolymer, styrene-acrylonitrile copolymer and the like are used. There is no particular limitation as long as it is a resin which can contain a foaming agent and can be foam-molded by in-mold beads, such as polyolefin resins such as polyethylene, polypropylene, ethylene-vinyl acetate copolymer and the like, and mixtures of these resins.

Specifically, for example, Table 1

First, the fan-shaped label 11 is wound around the pseudo core 10. That is, the roll film on which the display contents such as characters, patterns, and designs are printed in advance is set in a press machine having a Thomson blade and trimmed, and is the same as the body of the molded product, or the body of the molded product A fan-shaped label 10 having a shape having overlapping portions is produced. Then, the vacuum valve of the pseudo core 10 is opened to reduce the pressure in the air chamber 10c, so that the label 11 is sucked from the air holes 10b ... And wound around the pseudo core 10.

In this embodiment, as the label 11,
It is composed of polypropylene with a thickness of 30 μm printed on the back side and vinyl acetate / ethylene copolymer which is an adhesive layer with a thickness of 30 μm formed on polypropylene.
A film with a total thickness of 60 μm was used. Label 1
When the resin constituting No. 1 and the resin constituting the foamed bead cup are the same in quality, or when a printing ink having excellent adhesiveness is used, it is also possible to heat-bond both at the time of molding. However, when heat fusion with the foam bead cup is difficult, an adhesive layer for heat fusion is provided on the back side of the label 11 in order to secure the adhesion with the foam bead cup. The total thickness of the label 11 is 10 μm to 1
Although it can be molded in mm, it is more preferably 50 μm to 100 μm.

After that, water or an aqueous solution is sprayed on the inner surface of the cavity of the label 11 or the female mold 1 as described above.
Then, the forward valve of the pseudo core 10 is opened to open the pseudo core 10.
Is inserted into the female mold 1, and the pseudo core 10 and the female mold 1 are closed.
Next, by closing the vacuum valve of the pseudo core 10 and opening the compressed air valve, air is ejected from the air holes 10b ...
Are transferred from the pseudo core 10 to the female mold 1. This allows
The label 11 can be temporarily fixed to the inner surface of the cavity 3 of the female mold 1 with water or an aqueous solution interposed. Then, the pseudo core 10 is retracted and pulled out.

Subsequently, the female mold 1 and the core mold 2 are closed, the filling air valve is opened, and the cavity 3 is filled with the above-mentioned pre-expanded particles. Then, steam is introduced into the steam chamber 1a of the female mold 1 and the steam chamber 2a of the core mold 2 to heat them. At this time, the drain valve is opened and the condensed water is discharged.

Next, the direct heating valve is opened to directly heat the cavity 3. When the foamed particles are fused to each other, the cooling water valve is opened to cool the whole. After cooling, the discharge air valve is opened and the molded product is transferred to the core mold 2 side and discharged. Then, the movable platen 5 is lowered by the ram 6, the mold is opened, and the molded product is taken out.

A comparative experiment of the moisture-proof performance was carried out on the foamed resin cups thus produced which were provided with labels on the entire side surfaces and the foamed resin cups which were produced using the same apparatus without labeling.

Expanded polystyrene particles having a pre-expansion ratio of 12 are used for the cup, and the label 11 has a thickness of 6
A polypropylene sheet having a back surface of 0 μm and hot-melt processed was used. CaCl _{2 in} each 5 cups produced

[Table 2]

As described above, the manufacturing method of this embodiment has a structure in which the label 11 is temporarily fixed to the inner surface of the cavity by interposing water or an aqueous solution between the inner surface of the cavity of the female mold 1 and the label 11. . Therefore, the label 11 is closely attached to the inner surface of the cavity, and a gap is less likely to be formed between the label 11 and the inner surface of the cavity. Therefore, the pre-expanded particles are less likely to enter between the label 11 and the inner surface of the cavity, so that a good molded container can be obtained. Moreover, since foam molding is performed by steam heating, water has no adverse effect on the molded product. When heating with other than steam,
Water has almost no adverse effect on the molded article.

Further, if an aqueous solution having high wettability is used instead of water, even the label 11 that easily repels water can be closely fixed to the inner surface of the cavity without any clearance.

According to this embodiment, the foamed resin product with a label can be efficiently integrally molded in a small number of steps, and further, the position of the label 11 in the product does not shift and the label 11 can be easily peeled off. Nothing. Moreover, it is possible to easily manufacture a container or the like having a label 11 on the surface, on which a fine character display, a clear display in which gradation changes are smoothly expressed, and a display by multicolor overlay printing are printed. Furthermore, since there are no bubbles between the label 11 and the foamed resin product and the label 11 cannot be wrinkled, it is beautiful.

Further, it is not necessary to provide the deaeration passage and the deaeration hole, which are conventionally provided in the female mold for temporarily fixing the label 11, in the female mold 1 of this embodiment. Therefore, the structure of the female die 1 is simplified. Moreover, since the depression of the label 11 which is conventionally formed by sucking the label 11 into the deaeration hole is eliminated, the appearance of the product is significantly improved.

Further, since the label 11 having the back surface printed thereon is used, the ink of the printing layer is heated by the female mold 1 by heat.
Will not be transferred to. Therefore, printing defects due to transfer do not occur, and a labeled foamed resin product can be efficiently manufactured. In addition, by using resin instead of paper for the label 11, moisture is less likely to be absorbed even when steam heating is performed when a foamed resin product is molded.

A molded product obtained by integrally molding the label 11 on the entire side surface using a material excellent in gas barrier property as the label 11 is particularly suitable as a food container which is excellent in moisture proof and gas blocking effect and can be stored for a long time. Can be used.

The label 11 may be partially provided instead of the entire side surface. For example, the shape of the label 11 may be made shorter than the height of the body of the molded product as shown in FIG. 7. In this way, when it is provided only in the center of the body of the molded product, it is possible to prevent bulging of the body due to moisture absorption of contents such as ramen, and when it is provided only on the upper part of the body of the molded product. Makes it possible to reinforce the strength of the opening of the molded product and obtain a cheaper molded product.

In the above examples, the label 11 is composed of a base material layer (a transparent resin layer having a printing layer on the back surface) and an adhesive layer laminated on the back surface side of the base material layer as necessary. And a multilayer structure. Such a label 11 has a fan shape before being fused with the foamed resin particles in the mold, and can be integrated with the container after the fusion without being formed into a tubular shape. More specifically, it is preferable to use the label 11 having the structure shown below.

Materials used as the label 11 include polystyrene, polypropylene, high density polyethylene, polyvinyl chloride, polyethylene terephthalate,
A thermoplastic resin having a melting point of 135 to 264 ° C. such as polyamide, a resin film containing 8 to 65% by weight of an inorganic fine powder, or a film obtained by coating an inorganic filler-containing latex on the surface of the resin film, Alternatively, the resin film may be aluminum vapor-deposited. Such a base material layer may be a single layer or a laminated structure of two or more layers.

On the back side of the base material layer (the side in contact with the resin container), a low density polyethylene, a vinyl acetate / ethylene copolymer, an ethylene / (meth) acrylic acid copolymer, which serves as an adhesive layer if necessary. A metal salt of ethylene / (meth) acrylic acid copolymer can be used. Above all, a heat sealable resin having a melting point of 85 to 135 ° C. can be preferably used.

As described above, the printing layer 11 is formed on the back surface of the transparent resin layer 11a made of the resin film (or sheet).
By using the label 11 in which b is arranged (see FIG. 8), it is possible to obtain a foamed resin product with a label in which printing is hard to stain and which is always beautiful.

[0053]

As described above, in the labeled foamed resin product according to the first aspect of the present invention, the label comprising the transparent resin layer and the printed layer is adhered to the foamed resin product, and the printed layer of the label is transparent. The resin layer is disposed on the foamed resin product side with reference to the resin layer.

According to this, as compared with the foamed resin product using the conventional paper-made printing sheet, a labeled foamed resin product excellent in moisture resistance and gas barrier property can be obtained. Therefore, it is suitable for food containers and the like. Moreover, since the printing layer is arranged on the side of the foamed resin product, that is, on the inner side with respect to the transparent resin layer, the printing is hard to stain and is beautiful forever. Further, it is possible to easily manufacture a labeled foamed resin product by foaming resin molding.

As described above, in the method for producing a foamed resin product with a label according to the invention of claim 2, water or an aqueous solution is interposed between the inner surface of the cavity of the female mold and the label to form the label in the cavity. After temporarily fixed to the inner surface, the cavity is filled with pre-expanded particles and heat-foam-molded to produce a labeled resin foam product in which a label is adhered to the resin foam product.

According to this, the label can be easily attached to the inner surface of the female cavity without using the deaeration passage, and
Can be closely attached without gaps. This prevents the pre-expanded particles from entering between the label and the inner surface of the cavity of the female mold even when the pre-expanded particles are filled. In this state, heat-foam molding is performed to manufacture a labeled foamed resin product in which the label is adhered to the foamed resin product, so there is no dent in the label formed when the label is sucked into the degassing passage. There are no bubbles between the label and the foamed resin product, and the label cannot be wrinkled. That is, the label does not protrude from the surface of the foamed resin product, is beautiful, and is difficult to peel off. Further, since water or an aqueous solution is used for temporarily fixing the label, the foamed resin product is hardly adversely affected, and it is not necessary to provide a deaeration passage for temporarily fixing the label in the female mold. This makes it possible to display fine characters, a clear display that smoothly expresses changes in gradation,
It is possible to easily manufacture a foamed resin product such as a container having a label on which an indication is printed by multicolor overlay printing or the like.
