る。In the embossed sheet in the above-mentioned conventional example, the paper layer itself forming the sheet does not have a heat insulating structure, but an air trap between the embosses (valley between embosses) provides a heat insulating effect. A relatively large air pool is formed between the relatively large embosses, and the density of the air pool as a whole becomes a coarse density.

している。In addition, since the individual air reservoirs communicate with each other and are opened to the outside at the bottom end of the paper cup, that is, the bottom end of the embossed sheet, there is a problem that the heat insulating effect is poor.
【０００５】又個々のエンボスが外力により変形して

損なう問題を有している。Further, there is a problem that each emboss is deformed (crushed) by an external force and impairs the appearance of the outer surface of the cover sheet.

有する。The present invention seeks to remedy the above problems. The present invention is an insulating paper cup for beverages and foods, the insulating paper cup having an outer peripheral surface covered with a paper non-woven fabric, and the outer peripheral surface of the paper non-woven fabric covered with a paper cover sheet having a high pulp fiber density made of paperboard. Have a structure.

果を助長する。This heat insulating structure is preserved by forming a myriad of minute air-holding intervals in the paper layer of the paper non-woven fabric, and a very high heat insulating effect can be obtained. In addition, the flowability of air with the outside is very small, which promotes the heat insulating effect.

Rather, the paper non-woven fabric is interposed between the paper cup and the paper cover sheet to provide appropriate elasticity. It exhibits resilience, maintains a good appearance, and gives a good grip feeling with fingers.

帯状に接着剤付けする。The non-woven fabric made of paper and the cover sheet made of paper are laminated to each other with an adhesive, and the laminated sheet is wrapped around the outer peripheral surface of the paper cup with the non-woven fabric made of paper. Then, the winding end of this laminated sheet is abutted on a line extending from the opening end of the paper cup to the bottom end, and the inner surface of the abutting end of the non-woven fabric made of paper is adhered to the outer surface of the paper cup in a band-like shape on the butting line. At the same time, the inner peripheral surface of the bottom end of the non-woven fabric made of paper is adhered to the outer peripheral surface of the paper cup in a band shape.

A sealing band that satisfactorily infiltrates inside and blocks the flow of air in the same zone is formed.

成する。As shown in FIGS. 1 to 3, the outer peripheral surface of the paper cup 1 is covered with a paper non-woven fabric 2, and the outer peripheral surface of the paper non-woven fabric 2 is a flat paper having entangled pulp fibers. Cover with a cover sheet 3 made of material. As a result, a heat insulating structure is formed on the outer peripheral surface of the paper cup 1 by covering the innumerable multi-layered voids in the tissue itself of the paper non-woven fabric 2 with the paper cover sheet 3.

に打抜く。As shown in FIGS. 4 and 5, the paper non-woven fabric 2 and the paper cover sheet 3 are pasted together with an adhesive 5 to form a pasting sheet 6, which is prepared in advance. That is, the pasting sheet 6 is obtained by pasting the paper cover sheet 3 on one surface (outer surface) of the paper non-woven fabric 2 with the adhesive 5 and punching it into an arc-shaped plate. The paper cup 1 has a circular cross section and has a shape that converges toward the bottom end, and the above-mentioned laminating sheet 6 is punched into an arc-shaped plate from the laminating strip so as to conform to this.

持する。It is desirable that the entire surface of the laminated sheet 6 is bonded, and it is possible to bond the entire surface. The adhesive 5 is applied to the non-coated surface of the paper cover sheet 3 to form the paper non-woven fabric 2
Paste. The non-coated surface (inner surface) of the paper cover sheet 3 has a good impregnation property and absorbs the adhesive 5 to form a thin and uniform adhesive layer on the non-coated surface of the paper cover sheet 3 to form a paper non-woven fabric. At the time of pasting 2, the excessive swelling of the adhesive 5 into the layer of the non-woven fabric 2 (inside the void) is suppressed, and the multi-layer void inside the fibrous structure of the paper non-woven fabric 2 is favorably maintained.

The inner surface of the paper cup 1 is wrapped around the outer peripheral surface of the paper cup 1 in the circumferential direction and attached with an adhesive, and the non-woven paper sheet is formed between the outer peripheral surface of the paper cup 1 and the inner peripheral surface of the paper cover sheet 3. Three
A heat-insulating structure is obtained by interposing and sealing.

帯域を示す。The above-mentioned paper-made laminated sheet 6 preferably has a bonding structure described below, and has a heat insulating structure formed thereby. That is, as shown in FIG. 1, the wound end of the laminated sheet 6 is abutted on a line extending from the opening end to the bottom end of the outer peripheral surface of the paper cup 1, and as shown in FIGS. The winding end inner surface of the paper non-woven fabric 2 along the butt line 7 (bus bar) is attached to the paper cup in a band shape with the adhesive 8 and the bottom end inner peripheral surface of the paper non-woven fabric 2 is adhered to the paper cup. It is pasted in the shape of a band through the agent 9. In the figure, reference numerals 10 and 11 denote attachment zones by the adhesives 8 and 9.

る。The adhesives 8 and 9 are applied to the bonding zone 1
At 0 and 11, the wetting of the paper non-woven fabric 3 into the multi-layer voids is promoted, and the pasting zones 10 and 11 form a sealing band that blocks the flow of air. As a result, a shielded annular air layer is formed in the inner region of the sealing band so as to surround substantially the entire outer peripheral surface of the paper cup 1 over substantially the entire region of the paper non-woven fabric. This annular air layer and the multi-layered voids of the tissue of the paper non-woven fabric synergistically give the paper cup 1 a very good heat insulating effect.

状態となる。In other words, the inner peripheral surface of the paper non-woven fabric 2 is in a region other than the pasting zones 10 and 11 in the paper cup 1
To form a free contact surface 13 with respect to the outer peripheral surface, and form the closed annular air layer. As is known, the paper cup 1 has an annular rib 12 projecting outward at the open end, and the open end of the bonding sheet 6 is wrapped around the lower end of the annular rib 12 so as to annularly abut, Paste band 1
Paste with 0 and 11. Therefore, the paper non-woven fabric 3 is substantially completely sealed at the butting end, the opening end and the bottom end.

The paper cup 1 has an annular stand 14 on the periphery of the bottom plate in order to float and support the bottom of the cup. This annular stand does not form an inner space of the cup for containing the contents. Therefore, the bottom end of the paper non-woven fabric 2 is attached to the outer peripheral surface of the stand 14 with the adhesive 9 in an annular shape. By forming the attachment zone 11, it is possible to prevent the heat insulating effect from being diminished by the solidification of the adhesive 9, and the stand 14
Since the rib protrudes like a rib, the bonding work can be advantageously performed.
