Description

[0001] TOOTHBRUSH WITH 3-DIRECTIONAL BRUSH [0002]

The present disclosure relates to a toothbrush for removing toothpaste or foreign matter between teeth or teeth by wiping teeth with toothpaste.

Unless otherwise indicated herein, the description set forth in this identification section is not prior art to the claims of this application and is not to be construed as prior art as described in this identification section.

In general, the mouth is the starting point of digestive organs using teeth and tongue to chew food and mix with saliva. Therefore, it is very important to keep the mouth clean.

On the other hand, when food is consumed, food waste remains between the teeth, which is a good environment in which bacteria can reproduce. A toothbrush or a floss is used to remove it, and a toothbrush is mainly used. The toothbrush is made of a handle gripped by the user and a head with bristles placed on it, and is used in a way to clean the teeth and the gums with toothpaste on the bristles.

In the conventional toothbrush, all of the bristles of the same material are mainly arranged in the vertical direction, but in recent years, various bristles having different heights and different materials are used. This is because teeth size and shape are different depending on the individual or position. In other words, the front teeth, canines, and molars are different in size and shape, and the locations where teeth should be brushed are different from each other, such as between teeth and teeth, and between teeth and gums.

In addition, brushing is performed by various methods. In order to brush the occlusal surface of the teeth, the bristles are reciprocated by tooth-occlusal surfaces. Further, in order to brush the side of the tooth, the bristles are brushed to the side of the tooth so that the bristles reciprocate.

However, when the bristles are reciprocated by the side of the teeth, excessive force is applied to the tooth and the gum side, and the gap between the tooth and the gum is widened. In particular, the tooth gap can not be properly wiped. Because of this problem, brushing is performed by lifting the bristles from the lower part of the tooth to the upper part.

However, for adults, familiar brushing habits are not easily remedied, and children who are unfamiliar with brushing have difficulty brushing in this manner. Therefore, food waste or foreign matter can not be properly removed from the teeth, causing tooth decay or gum disease.

In order to solve such a problem, Korean Patent Laid-Open Publication No. 10-2014-0134081 (published on November 21, 2014) discloses a toothbrush which is formed in a U shape so as to simultaneously wipe a sagittal surface, a snow surface and an occlusal surface of a tooth, And a handle portion integrally connected to the head portion, wherein the connection member of the toothbrush head portion is formed by a U-shaped head member formed by connecting U And a cleaning discharge groove is formed between the U-shaped head members at both sides of the U-shaped head member. The connecting member of the toothbrush head unit is formed of an elastic material capable of being elastically deformed.

Wherein the base member and the first sidewall and the second sidewall have bristles thereon extending into the space and wherein at least one of the first sidewall and the second sidewall has a bristle extending into the space Disclosed is a toothbrush pivotable relative to the base member to permit entry and removal from space.

Also, Korean Patent Laid-Open Publication No. 10-2017-0067573 (published on June 16, 2017) discloses a toothbrush comprising a toothbrush head, a handle, and a connecting portion connecting the toothbrush head and the handle portion, A first toothbrush head; A first elongate portion extending upwardly from one side of the first toothbrush head and a first soft toothbrush head formed obliquely to the first toothbrush head at an end of the first elongate portion and having an outer surface flexed; 2 toothbrush heads; And a second flexible toothbrush head having a second extension extending in an upper direction from the other side portion of the first toothbrush head and an outer surface being curved at an end of the second extension formed obliquely to the first toothbrush head. A toothbrush comprising a three toothbrush head is disclosed.

In the case of the conventional toothbrush as described above, since the toothbrush head portion is formed in a U-shape, the bristles contacting both side surfaces of the tooth are mainly worn out than the bristles contacting the occlusal surface of the tooth. Even if the bristles contacting the occlusal surfaces of the teeth are not worn, the bristles contacting both sides of the teeth are worn out. Therefore, the entire toothbrush must be replaced, which not only burdens the user economically but also increases the environmental pollution due to the disposal of the entire toothbrush have.

Further, in the case of the conventional toothbrush as described above, since the upper ends of the bristles contacting the occlusal surfaces of the teeth are formed at the same height, there is a problem that the front teeth and the canines having less occlusal surfaces are not properly wiped.
