Summary of the Invention

Problems to be Solved by the Invention

[0004] In a flat oral insert such as an ice candy stick, if the corner between the main surface and the end surface is sharp, there is a risk of damaging the mouth. In view of such circumstances, an object of the present invention is to prevent the mouth from being damaged by the corner between the main surface and the end surface when an elongated and flat oral insert is inserted into the mouth.

Means for Solving the Problems

[0005] To solve the above problems, the present invention is a flat oral insert for eating and drinking or for medical and hygienic use made of paper extending in the axial direction, including main surfaces on both sides in the thickness direction orthogonal to the axial direction, and circumferential end surfaces between the outer edges of these main surfaces, The circumferential end face is characterized by having a pair of circumferential end face portions that protrude outward from the outer edges of each of the main faces on both sides and intersect at an obtuse angle.

[0006] Preferably, the inclination of each circumferential end face portion with respect to the main face becomes steeper as it protrudes from the outer edge.

[0007] Preferably, between the pair of circumferential end face portions, streak-like marks are formed so as to extend in the circumferential direction of the circumferential end face.

[0008] Preferably, the surface roughness of each circumferential end face portion is substantially the same as the surface roughness of the main face.

[0009] Preferably, it includes a flat main portion and an outer peripheral portion that protrudes outward from the main portion, the main face constitutes the surface of the main portion, the circumferential end face constitutes the surface of the outer peripheral portion, and the paper fiber density in the outer peripheral portion is higher than the paper fiber density in the main portion.

Advantages of the Invention

[0010] According to the present invention, it is possible to prevent the mouth from being damaged by alleviating the sharpness of the corner between the main face and the end face of the oral insert.

Embodiments for Carrying Out the Invention

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figure 1 shows the core rod 10 (oral insert) of the ice candy 1 (food or drink). The core rod 10 is made of paper. Preferably, the paper material constituting the core rod 10 may be pulp paper or synthetic paper. The core rod 10 may be composed of a single-layer paper sheet, or may be composed of a laminated paper sheet in which a plurality of paper sheets are laminated via an adhesive layer. The core rod 10 is produced by punching and separating a single-layer paper sheet or a laminated paper sheet.

[0013] As shown in Figure 1, the core rod 10 is formed in an elongated shape extending in the axial direction (vertical in Figure 1). And as shown in Figure 2, the core rod 10 is flat, with the thickness (dimension in the vertical direction in Figure 2) being smaller than the width (dimension in the left-right direction in Figure 2). The axial direction, thickness direction, and width direction of the core rod 10 are perpendicular to each other. The thickness t of the core rod 10 10 is preferably about t 10 = 1 mm to about 10 mm.

[0014] As shown in Figures 1 and 2, the core rod 10 includes a flat main portion 10a and an outer peripheral portion 10e. The surfaces on both sides (upper and lower in Figure 2) in the thickness direction of the main portion 10a constitute the main surfaces 11. The main surfaces 11 are flat. The pair of main surfaces 11 are parallel.

[0015] As shown in Figure 3, the outer peripheral portion 10e of the core rod 10 protrudes outward (left side in Figure 3) from the virtual line L connecting the outer edges 11e on both sides (upper and lower in Figure 3) in the thickness direction of the main portion 10a. The virtual line L virtually indicates the boundary between the main portion 10a and the outer peripheral portion 10e. The surface of the outer peripheral portion 10e is the circumferential end surface 12. In other words, the surface of the core rod 10 includes the main surfaces 11 on both sides (upper and lower in Figure 2) in the thickness direction and the circumferential end surface 12 between the outer edges 11e of these main surfaces 11. As shown in Figure 1, the circumferential end surface 12 is annular over the entire circumference of the core rod 10.

[0016] As shown in Fig. 2, the peripheral end face 12 has a pair of peripheral end face portions 12a and streaks 13. As shown in Fig. 3, the peripheral end face portions 12a protrude outward from the outer edge 11e of each main face 11. As a result, the thickness t of the outer peripheral portion 10e 10e becomes smaller as it goes outward (leftward in Fig. 3). Preferably, the paper fiber density in the outer peripheral portion 10e is higher than the paper fiber density in the flat main portion 10a between the main faces 11 on both sides of the mandrel 10. More preferably, the paper fiber density in the outer peripheral portion 10e increases as it goes outward (leftward in Fig. 3). Thereby, the strength of the mandrel 10 can be increased.

[0017] As shown in Fig. 3, the inclination of each peripheral end face portion 12a with respect to the main face 11 becomes steeper as it protrudes from the outer edge 11e. The corner formed between the main face 11 and each peripheral end face portion 12a is a rounded arc portion 12b. The pair of peripheral end face portions 12a intersect at an obtuse angle at the central portion 12c in the thickness direction of the peripheral end face 12.

[0018] Preferably, each peripheral end face portion 12a has a smooth surface equivalent to the main face 11. That is, preferably, the surface roughness of the peripheral end face portion 12a is substantially the same as the surface roughness of the main face 11.

[0019] As shown in Fig. 2, a small protruding streak 13 is formed between the pair of peripheral end face portions 12a at the central portion 12c of the peripheral end face 12. The pair of peripheral end face portions 12a intersect via the streak 13. As shown in Fig. 1, the streak 13 is formed to extend in the circumferential direction of the peripheral end face 12. Preferably, the streak 13 extends annularly over the entire circumference of the peripheral end face 12.

[0020] As shown in Fig. 3, the streak 13 is in the form of a tear mark formed by tearing the paper and is composed of paper fibers that were fluff. Therefore, the streak 13 has a rougher surface than the peripheral end face portion 12a. The width w of the streak 13 along the thickness direction of the mandrel 10 13 is preferably w 13It is about 1 μm to 1 mm. The width w of the stripe 13 13 is about one ten-thousandth to one tenth of the thickness t of the mandrel 10. 10 The protruding height h of the stripe 13 13 is preferably h 13 =1 μm to 1 mm.

[0021] As shown by the dashed-two-dot line in FIG. 1, an ice candy 1 is provided on the outer periphery of the mandrel 10. By embedding the stripe 13 with a rough surface roughness inside the ice candy 1, the adhesion strength between the mandrel 10 and the ice candy 1 is increased. Since the corner portion between the main surface 11 and the peripheral end surface 12 of the mandrel 10 is a rounded portion 12b, even if the corner portion of the mandrel 10 touches the tissue in the mouth when the mandrel 10 is put into the mouth, it is possible to prevent the mouth from being damaged. Since the stripe 13 is in the form of paper fibers with fluff, it does not damage the mouth.

[0022] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit thereof. For example, the oral insert according to the present invention may be not limited to the mandrel of the ice candy, but may be other oral inserts for eating and drinking (for example, spoons, forks, knives, and other cutlery), or may be oral inserts for medical and hygienic use such as tongue depressors and toothbrushes. The pair of peripheral end faces 12a do not necessarily have to intersect at the central portion 12c in the thickness direction of the peripheral end face 12, and may intersect at a position offset toward the main surface 11 side (for example, the lower side) in the thickness direction of the peripheral end face 12. The stripe 13 is not limited to being disposed at the central portion 12c in the thickness direction of the peripheral end face 12, and may be disposed offset toward the main surface 11 side (for example, the lower side).

Industrial Applicability

[0023] The present invention can be applied to, for example, the mandrel of an ice candy.
