Heat-retaining containers for hot water foods can be made by forming a heat-insulating layer on the outside of a paper cup laminated with polyethylene on the inside, by heat-forming foamed polystyrene sheets, or by foaming and heat-sealing foamed polystyrene beads. The resulting bead-foamed container or a container consisting of a double structure of an inner container of a non-foamed plastic container and an outer container made of paper are known.

Widely used as a disposable container.

ことが広く行なわれている。[Problems to be Solved by the Invention] Cups made of expanded polystyrene beads are suitable as disposable containers, but the bead-like appearance remains even after molding, making it difficult to improve the surface properties. In addition, direct printing on curved surfaces may be performed in order to provide a design, but this also has the disadvantage that precise multicolor printing cannot be performed. As a method for improving these drawbacks, it is widely practiced to heat-shrink a preprinted heat-shrinkable plastic film to cover the bead-foamed polystyrene cup.

には危険な場合もあつた。 In the above packaging method, the beaded polystyrene cup is generally shrink-packed together with the lid, and when it is ready for consumption, the film is torn along the pre-formed perforations and the film that covers the lid is removed. Remove and open. However, after opening the bead foam polystyrene container and the film covering them, they tend to slip between each other, making it inconvenient to handle when stirring the contents after pouring hot water, especially when pouring boiling water. In some cases, it was dangerous to carry it around immediately after use.

合があることなど問題がある。 As a technique to solve this problem, for example,
There is a container shown in No. 62-13946. However, in the manufacturing process of this container, when a heat-shrinkable sleeve made of a heat-shrinkable film coated with a heat-fusible adhesive is heat-shrinked, the adhesive is melted, so the adhesive layer is The heat-shrinkable film does not necessarily adhere to the foamed plastic container as the base material, since the joints of the sleeve are easily dislodged, and the adhesive is melted while the sleeve is shrinking. There are problems in that the heat-shrinkable film is not fixed, but may shift.

As a result of various studies regarding the above issues,
The above-mentioned problems can be solved by covering the bead-expanded polystyrene cup, which is the base material of the container of the present invention, with a heat-shrinkable laminated sheet made of a heat-shrinkable polystyrene resin foam sheet and laminated with a polystyrene film. I found a solution.

ツプに固定することが出来る。 That is, unlike the case of a single heat-shrinkable non-foamed film, a heat-shrinkable laminated sheet with a polystyrene film based on a heat-shrinkable polystyrene foam sheet does not only shrink when heated, but also slightly shrinks when heated. Since it causes foaming, it can be closely attached to the surface of the beaded foamed polystyrene cup that serves as the base material. This allows a label made of a laminated sheet to be fixed to a cup made of beaded expanded polystyrene.

出来る。 In the present invention, a printed film is used in which a transparent polystyrene film exhibiting heat shrinkability in the flow direction is printed on the back side with a printing ink containing a thermoplastic polymethacrylic acid ester binder. Since printing is performed on a smooth film, much more precise multicolor printing can be easily performed than when printing on a curved surface directly on a cup made of expanded bead polystyrene.

樹脂発泡シートを製造出来る。 By putting the raw material polystyrene resin and additives into an extruder for plastic foaming and kneading them, and then press-fitting the foaming agent and taking it out while extruding, we can produce polystyrene resin foam that exhibits heat shrinkability equivalent to that of the printed film. We can manufacture sheets.

In order for the polystyrene resin foam sheet, which is the base material, to foam appropriately when heat-shrinking the heat-shrinkable laminated sheet, the residual gas content in the heat-shrinkable polystyrene resin foam sheet after extrusion must be adjusted to 0.5 to 6.0%. There is a need to.

性スリーブの内径は基材であるビーズ発泡ポリス
チレン製カツプの外側面の最大径と等しくする。 A heat-shrinkable printed film and a heat-shrinkable polystyrene-based resin foam sheet are stacked together with the printed layer of the printed film in such a way that the directions of shrinkage of each layer match, and the heat-shrinkable printed film and the heat-shrinkable polystyrene resin foam sheet are bonded under heat and pressure under conditions that do not cause heat shrinkage. A heat-shrinkable laminate sheet used in the present invention is thus obtained.
Next, a heat-shrinkable sleeve is made from the heat-shrinkable laminated sheet so that the flow direction of the heat-shrinkable laminated sheet coincides with the circumferential direction of the cylindrical sleeve. The inner diameter of this heat-shrinkable sleeve is equal to the maximum diameter of the outer surface of the beaded expanded polystyrene cup that is the base material.

された断熱性カツプを製造することが出来る。 This heat-shrinkable sleeve is placed over a cup made of expanded polystyrene beads and left in a hot air atmosphere of 130°C for 30 seconds to 200°C for 5 seconds, thereby forming a styrene resin foam sheet on the outside surface of the cup made of expanded polystyrene beads. It is possible to manufacture a heat insulating cup in which a laminated sheet as a material is closely fixed.

縮率が同じ条件で10％以下であることが必要であ
る。 If the heat-shrinkable sleeve has a large heat-shrinkability in the vertical direction, the sleeve will shrink in the vertical direction and be removed from the container when it is heated and shrunk. In order to prevent this, the heat shrinkage rate of the heat-shrinkable laminated sheet constituting the heat-shrinkable sleeve in the machine direction is 60% or more under the conditions under which the heat-shrinkable sleeve is heat-shrinked, and the heat shrinkage rate in the machine direction and the perpendicular direction are the same. It is necessary that the condition is 10% or less.

The present invention has developed a method of making bead foamed polystyrene cups that have been widely used in the past by closely covering them with a laminated sheet made by laminating a polystyrene film on a polystyrene foam sheet as a base material.

る。 Also, unlike the conventional case where the container is covered with a single printing film, since the container body and the label are fixed, there is no chance of the label slipping or coming off. Furthermore, since the outside of the container can be reinforced with a laminated sheet based on a polystyrene foam sheet, which has superior rigidity compared to a single film, it has the advantage of providing a container with excellent strength.

A polystyrene resin foam sheet with a thickness of 0.1 to 1.0 mm and a transparent polystyrene film whose back side is printed with a printing ink containing a thermoplastic polymethacrylic acid ester binder are pasted on the printed surface. A heat-insulating cup characterized in that the transparent film side of the combined laminated sheets is placed on the outside of a beaded polystyrene foam cup. 2. Back printing is performed on one side of a heat-shrinkable transparent polystyrene film using a printing ink containing a thermoplastic polymethacrylic acid ester binder, and a heat-shrinkable polystyrene resin foam sheet with a thickness of 0.1 to 1.0 mm is applied to the printed surface. A heat-shrinkable laminated sheet is made by heat-pressing the transparent polystyrene film and the polystyrene resin foam sheet under conditions that do not cause heat shrinkage, and the laminated sheet is made into a cylindrical sleeve with the transparent polystyrene film side facing outward. After that, the sleeve is placed on the outside of a cup made of expanded polystyrene beads, and the sleeve is heat-shrinked so as to be brought into close contact with the surface of the cup.
