Problems solved by technology

[0006] Common measures to increase the elasticity of the monofilaments are to increase the diameter of the circular cross-section monofilaments, or to make the monofilaments from harder materials, however, an increase in cleaning ability can hardly be expected from these measures alone
The reason is that when the diameter of the monofilament is increased or the monofilament is made of a harder material, the tissues inside the oral cavity feel too much stimulation due to contact with the monofilament, and when only these measures are used, the rigid end has Possibility of failing to reach fine spaces between teeth

Embodiment Construction

[0069] The invention will be explained below by means of some examples in which details of the invention are described. Unless otherwise stated, in the following description, the length direction refers to the length direction of the handle, and the width direction refers to the width direction of the handle. The length direction of the handle is consistent with the length direction of the cluster base, and the width direction of the handle is consistent with the width direction of the cluster base.

[0070] figure 1 The handle is shown before the tow is embedded. Toothbrush of the present invention is characterized in that as figure 1 The state of the bunched part is shown at A, while the neck B and handle C may have any shape. The structure of the bundle portion A will be explained below.

[0071] The toothbrush of the present invention is characterized in that the openings serving as the converging holes formed in the converging portion are approximately elliptical or n...

Abstract

A toothbrush enhanced in a portions-between-teeth cleaning performance without sacrifice in a smooth-surface cleaning performance; specifically a toothbrush which is capable of, as its main theme, enhancing a portions-between-teeth cleaning performance and providing durability for maintaining the performance and which is, as its sub-theme, excellent in appearance and durability. To attain the main theme, tuft holes formed in a block head are in an approximately oval or rectangular shape, the tuft holes are inclined with respect to the block head surface and mono-filaments in rectangular cross section are used to increase a cleaning performance. To attain the sub-theme, a method of driving parallel lines are disclosed such that adjacent tuft holes are staggered with each other so that the driven parallel lines do not lie on a linear line.

Description

technical field [0001] The present invention relates to a toothbrush which has an excellent ability to clean interdental spaces and neck portions, and has an excellent ability to clean smooth surfaces such as tooth surfaces. Background technique [0002] The toothbrush cleans or brushes the teeth in the oral cavity through the elasticity of the monofilament contained in the tow embedded in the bundle hole of the handle. Since the cleaning effect increases with increasing elasticity, toothbrushes are required to have high elasticity mainly in the brushing direction. In addition, the toothbrush needs to be adapted to the state of the part being cleaned, so as to perform a specific cleaning action on each individual part. There are various types of cleaning ability with respect to the state of the part to be cleaned, but typical examples are the ability to clean smooth surfaces such as tooth surfaces and the ability to clean fine spaces in teeth. The fine space includes the i...
