Dental floss stick with tight and straight dental floss as well as manufacturing equipment and manufacturing method for dental floss stick

Abstract

The invention provides a dental floss stick with a tight and straight dental floss as well as manufacturing equipment and a manufacturing method for the dental floss stick. The dental floss stick comprises a handle and a dental floss bracket, wherein the dental floss bracket comprises a first bracket and a second bracket which are integrally molded; a dental floss which is tightened to be a straight line is arranged between the first bracket and the second bracket. Along the dental floss length direction, opposite sides of the first and the second brackets are inner sides, and the far-away sides of the first and the second brackets are outer sides; thicknesses of the first and the second brackets are gradually reduced from the outer sides to the inner sides. The manufacturing equipment is a special mould, depth of a part, corresponding to the dental floss bracket, of a mould cavity of the special mould is gradually shrunk and reduced from the outer side of the dental floss bracket to the inner side of the dental floss bracket. The dental floss stick is integrally injection-molded in the special mould; in the injection-molding process, the shrinking percentage of the part, closer to the outer side, of the material of the dental floss bracket part is relatively large, and the dental floss is tightened and straightened by tensile force produced by large shrinkage percentage of the outer side to form the dental floss stick with tight and straight dental floss. The obtained dental floss stick is suitable for various dental flosses, so that the dental floss has enough tension to meet oral-cavity cleaning needs.

Description

technical field [0001] The invention relates to an oral cleaning appliance, in particular to a dental floss stick with straightened dental floss and its manufacturing equipment and manufacturing method. Background technique [0002] Dental floss is a product that is used together with a toothbrush in daily oral care. Dental floss can easily reach narrow gaps between teeth that are difficult to reach for brushing, rinsing and flossing, and effectively remove food residue and plaque between teeth And soft tartar, thereby reducing the discomfort of foreign matter impaction between teeth, and improving oral hygiene. Medical research shows that flossing is better at preventing dental disease than toothbrushing. [0003] Dental floss sticks have gradually become familiar to consumers in recent years. Such as Figure 1 to Figure 2 As shown in the dental floss stick, the dental floss 2 is fixed on the stick body 1 , and the user can hold the stick body 1 and use the dental floss 2...

AI Technical Summary

Problems solved by technology

In the past, dental floss was mostly made of nylon thread, silk thread, polyester thread or waxed cotton thread, but this kind of dental floss is easy to wear and has insufficient toughness, so it is gradually replaced by new fiber materials such as body armor thread

These new materials have higher toughness and better wear resistance, but when combined with traditional sticks, the dental floss on the manufactured floss stick often cannot be straightened, resulting in insufficient tension of the dental floss, which affects the dental floss stick cleaning effect
