Description

Comb toothpick manufacturing method

Technical field

The invention relates to a method for manufacturing a comb toothpick, in particular to a method for processing the surface of a comb toothpick.

Background technique

Referring to the cross-sectional view of the conventional comb toothpick shown in Fig. 1, most of the comb-like or row-shaped toothpicks currently sold in the market are disclosed in the Taiwan Patent No. M304327, "Separable Plate-shaped Toothpick Structure". The shape of the body is mainly made into a continuous separable comb-like (row-like) design, and the toothpick 60 body design has a holding section 61 and a sharp-pointed cutting section 62 from the side, the toothpick 60 is made on When forming, the bottom of the plurality of toothpicks 60 is connected into a row of comb-like (row-like) continuous bodies, and is used after being pulled away from a toothpick 60 on the side of the comb-like (row-like) continuous body, which is known from the front view section. When the toothpick 60 is separated into a single toothpick 60, the tip of the toothpick 60 forms a tip 601, so that the toothpick 60 is in an upwardly tapered manner in the front cross section, but the actual shape of the toothpick 60 is smooth and the upward straight shape is in the structural strength. Insufficient, easy to cause breakage.

Moreover, the toothpick 60 body is designed to pick up the food slag of the tooth gap only at the front end of the toothpick 60, and the food swarf adhered to the gingival surface can only use the tip of the tooth segment 62. Repeatedly picking, but because the shape of the tip of the tooth section 62 is too sharp, it is easy to stab the epidermis during the provocation process, and the safety is insufficient and the injury is more likely to be infected. The main reason is that the aforementioned existing toothpicks have a tip except The side edges of the toothpicks 60 do not have any auxiliary features that allow the toothpick to make corresponding contact with the tooth surface on each of the action surfaces.

Moreover, the sides of the existing toothpicks 60 have a smooth shape, and the smooth surface has insufficient surface strength, so when the bottom of the toothpick 60 is used after being separated from the comb-like (row-like) continuous body, The strength of the two sides of the toothpick 60 is insufficient to cause the tooth to feel too soft to produce a sufficient relative force to perform the tooth picking operation, resulting in a convenient and practical use of the toothpick 60 of this type.
