Description

Manual children's toothbrush with interchangeable head consisting of a removable and ergonomic toothbrush head and an ergonomic toothbrush handle.

The present invention relates to a manual toothbrush for children and more particularly to an improvement of an existing fastening system for an adult brush which makes it possible to change the head of the toothbrush and therefore to change only the worn part of the brush. for child.

Toothbrushes have been known for many years. Currently manual toothbrushes are used by the entire population. Consumers are increasingly demanding when it comes to the quality and use of toothbrushes.

Current manual toothbrushes have drawbacks, particularly from an ecological point of view, since the entire toothbrush is thrown away when only the bristles are worn.

• La partie interchangeable qui représente près du tiers de la totalité de la brosse. Ce qui n’est donc pas très efficace d’un point de vue écologique.
• Le système de fixation de mauvaise qualité qui ne permet pas une durée de vie de la brosse très importante.
• Les brosses à dents manuelles à tête rechargeables présentes sur le marché actuellement ne sont pas adaptées en termes de taille de brosse et de taille de manche à une utilisation par des enfants.

There are already toothbrushes with interchangeable heads on the market, but these have many disadvantages, in particular:

• The interchangeable part which represents almost a third of the entire brush. Which is therefore not very efficient from an ecological point of view.
• The poor quality fixing system which does not allow a very long life of the brush.
• Manual toothbrushes with rechargeable heads currently on the market are not suitable in terms of brush size and handle size for use by children.

Thus, the present invention proposes to solve the aforementioned drawbacks using simple, reliable and easy-to-implement means.

According to the main characteristic of the toothbrush according to the invention, the interchangeable toothbrush head is of the type having the shape of a plate comprising tufts of bristles constituting the brush part, intended to rest on the teeth of the user when brushing. This part is housed in a toothbrush handle by means of fixing means and is characterized in that this fixing means is simple to produce, reliable and solid.

According to an additional characteristic, the interchangeable part is reduced to a minimum so that the ecological impact is as low as possible. Indeed only the bristles of the brush are thus changed when they are worn.

According to another characteristic, the size of the head of the toothbrush is adapted in order to allow optimal brushing of the teeth in the mouth of a child. The width and length of the toothbrush head are thus reduced and profiled in order to allow access to the back teeth of a child's mouth, which is by nature smaller than an adult's mouth.

According to another characteristic, the grip of the handle has also been worked on so that a child can easily grasp the handle and thus effectively brush their teeth. The handle is thus more curved and smaller than an adult toothbrush handle.

According to another characteristic, the fixing means is constituted by a set of longitudinal retainers by the principle of male/female interlocking.

According to another feature, the means for fixing the toothbrush head is designed to be produced by the plastic injection molding technique.

According to another characteristic, the toothbrush head holds in place in the handle thanks to the elasticity of the plastic material used to design the handle. The male part (the brush head) is inserted by the user into the handle of the brush (female part) by exerting a force which separates the plastic material from the handle. Once the longitudinal restraints are found in front of the gutters of the handle provided to accommodate them, the plastic material of the handle comes back into place and the head is thus held in place.

According to another characteristic, the handle of the toothbrush is pierced right through at the rear of the head fixing system in order to be able to remove the head of the toothbrush by pushing the head of the toothbrush from the back of the handle.

Other characteristics and advantages of the invention will emerge from the description which will follow with regard to the appended drawings which are given only by way of non-limiting example.
