Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a steamed confectionery paper cup, and more particularly to a paper cup having a shape-retaining power when steaming and heating confectionery dough.

[0002]

[Prior art]

 As a paper cup of this kind and a method of manufacturing the same, there is a conventional one described in, for example, Japanese Patent Application Laid-Open No. 1-2226548 previously proposed by the present applicant. In this conventional technique, a thin paper sheet is cut into a disc shape, a circular fold is formed on the disc body by a creasing machine, and an inward fold and an outer fold are formed between the fold and the outer edge of the disc body. Orientation folds are formed radially at predetermined pitches, outwardly folded folds outward, inward folds and circular folds side plate components inwardly, and bonded to the outer surfaces of the folded portions. It is a paper cup in which the folded portion is attached to the outside of the side plate constituting portion after the agent is applied by a gluing machine, and a method for producing the same.

[0003]

[Problems to be solved by the invention]

 According to the above-mentioned conventional technology, the glue or adhesive for bonding the folded inner surface to the outer surface of the side plate required for the shape keeping of the paper cup side plate is made of polyvinyl alcohol (PVA) or dextrin which is harmless for food hygiene. Since the use of re-wet adhesives and starch glue is forced, the range of use as paper cups is greatly restricted. It cannot be used as a paper cup for steamed confectionery for sale.

[0004] That is, the pressure due to the thermal expansion of the steamed confectionery dough in the steaming pot is strongly applied to the side plate-bonded portions made of the PVA, dextrin, or starch paste melted and softened by high-temperature steam, and these bonded portions are peeled off to form a dish. The confectionery dough does not become steamed confectionery as a result of spreading and spilling out of the confectionery from the paper cup. In this conventional example, if a temporary disposable drinking cup is used, the rabbit will not be used, nor will it be used as a steamed confectionery cup. And there were serious problems.

In order to eliminate the above-mentioned problems, the present invention is strong in a high-temperature and high-humidity atmosphere and is suitable for living organisms as an adhesive medium between the inner surface of the folded side portion of the side plate and the outer surface of the side plate, which is necessary for the standing shape of the paper cup side plate. The purpose is to obtain a steamed confectionery paper cup by using a harmless polyethylene coating.

[0006]

[Means for Solving the Problems]

 The purpose of the present invention is to form a paper cup by folding a paper leaf from a number of folds into a cup-shaped paper cup, and to cover the outer surface of the cup with a polyethylene laminate layer (hereinafter simply referred to as a poly-laminate layer). A bottom plate is formed concentrically on a circular paper by upward folds, and a number of radially inward folds and outward folds slightly inclined to one side are formed on the outer side of the bottom plate. The side plates each having alternately formed elongated wedge-shaped folded portions and elongated trapezoidal unit side plate portions formed and formed by each of the folds are folded up from the upward fold, and the folded portions are respectively unit side plates. Folds along the outside of the unit, and heat-presses and adheres the poly-laminate layer adhered to the outer surface of each folded portion to the outer poly-layer of the unit side plate. In Rukoto it could be achieved by the side plates and raising the shape-retention of the upward fold.

[0007]

[Embodiment of the invention]

 First, as shown in FIG. 1 and FIG. 2, the basic form of the present invention is to use glassine paper or kraft paper as the paper cup material 10 and to apply the poly-laminate layer P to the outer surface of the cup as described above. A so-called "poly-laminate paper" attached by a known means is used. Then, a bottom plate 13 partitioned by concentric substantially circular folds 12 is formed at the center of a circular paper 11 obtained by punching the above material in a circular shape, and the substantially circular fold 12 and the outer edge 14 of the circular paper 11 are formed. A plurality of radially inward folds 15, 15 are provided between which the extension extends through the center of the disk body 11 and divides the outer edge 14.

The plurality of outward folds 15, 15 are in contact with the inward folds 15, 15 at the positions of the substantially circular folds 12, and are inclined at a predetermined angle with respect to the inward folds 15, 15 in one direction. 2 and FIG. 2 show an elongated wedge-shaped folded portion 17 and an elongated trapezoidal unit side plate portion 18 which are formed by forming the folds 16 and 16 by the inward folds 15 and 15 and the outward folds 16 and 16, respectively. As shown in FIG. 3, side plates 19 are formed alternately.

Next, the elongated wedge-shaped folded portions 17, 17 are attached to the outside of the unit side plate portion 18 and are erected from the upward folds 12, and the polylamin layer P inside the outer surface of each of the folded portions 17, 17 is attached to the unit side plate. A heat-pressing and clamping device is used to adhere to the polylaminar layer P on the outer surfaces of the portions 18 and 18 by using a well-known heating and pressure-clamping device.

That is, a side plate 19 and a bottom plate 13 in which a wedge-shaped folded portion 17 and a substantially trapezoidal unit side plate portion 18 divided by an inward fold 15 and an outward fold 16 are alternately adhered and connected with the polylaminate layer P. And the paper cup can be integrally configured.
