Description

Toothbrush with toothpaste embedded brush head refill

The present invention relates to a toothbrush having a toothbrush embedded toothpaste type 2-3 disposable brush heads, and in particular, the toothpaste extrusion structure can be built while the body can achieve a sleek functional structure, without brushing or exterior design design restrictions and at the same time simple structure 2 The present invention relates to a toothbrush having a toothpaste type 2-3 disposable brush head refill, which can be used semi-permanently by replacing a brush head refill containing a 3-time toothpaste.

In general, after ingestion, a portion of the food is sandwiched between the interdental and fine food residues remain in the tongue oral cavity in the oral cavity. Therefore, it is recommended to brush your teeth within 3 minutes if you consume food or drinks. The purpose of this brushing is to prevent food residues from remaining inside and outside the occlusal surface and, more precisely, to remove plaque, a colorless membrane that sticks between teeth and gums.

However, if you do not brush your teeth in the right way at the right time, oral cavity, gums, tongue, etc., inflammation and swelling may cause bad breath or gingivitis or tooth decay.

In other words, human teeth seem to be hardened on the surface, but they are living tissues like other parts of the body, and acid is generated when the parasitic bacteria in the oral cavity act on the sugars in the food residues that remain between the interdentals after eating. These acids melt the enamel layer protecting it, causing bacterial destruction, or tooth decay.

Therefore, in order to prevent such oral diseases or to prevent the spread of oral inflammation or tooth decay that has already occurred, it is possible to reduce the eating habits suitable for oneself, for example, sugary foods or increase their resistance to acid erosion to prevent tooth decay. It is necessary to properly brush teeth while using a functional toothpaste such as a fluoride-containing toothpaste or a toothpaste containing a herbal ingredient having an antibacterial action.

However, when looking at these brushing habits, most people brush their teeth with a lot of toothpaste on the surface of the toothbrush.In this case, the toothpaste on the surface of the toothbrush is mixed with saliva or water, and bubbles form at once. The bubbles will fill up, so it's common to spit them out before you finish brushing your teeth. In this case, children, especially children who don't like to brush their teeth, will spit out even a little foam in their mouths.

Therefore, in order to brush teeth effectively, it takes about 3 minutes to brush every corner of the gum, so it is desirable to apply the toothpaste deeply to the toothbrush and then to the toothpaste on the toothbrush slowly melted from the top and discharged to the end of the toothbrush during brushing. Do. Therefore, there is a need for a new method or device for automatically dissolving toothpaste slowly.

On the other hand, the proper amount of toothpaste is known to be about 3g at a time, but due to the influence of excessive toothpaste advertisement through the mass media of toothpaste companies, the amount of toothpaste was wasted a lot because it is actually used several times. It is becoming. Therefore, there is a need for a method or apparatus for inducing only an appropriate amount to be used at a time.

Moreover, when using the proper amount, it is necessary to use the toothpaste deeply buried in the toothbrush, but since it is not easy to keep it, there is a need for a new method to induce it to be automatically or compulsory.

In addition, another way to save toothpaste is to use a toothpaste extruder that makes it easy to use all the toothpaste remaining in the toothpaste container when the toothpaste is almost exhausted, but in this case you need to purchase it separately, it is cumbersome and removable. none.

In addition, in the past, a number of toothpaste-type toothbrushes that can be easily carried by incorporating toothpaste in the toothbrush as disposable toothbrushes or portable toothbrushes when traveling are proposed.

For example, such a toothpaste-type toothbrush has a brush (4) formed with a toothbrush (4) filled with toothpaste filled in the internal space by moving the sliding knob (3) of the toothpaste (1) embedded in the body (2) as shown in FIG. 5) and extruded through the outlet 6 and discharged between the brushes (4) (see Korean Patent Registration No. 78348).

The one-piece structure refills the space inside the body 2 at the same time the brush body 2 is large and the elasticity of the neck is reduced due to the space for accommodating the toothpaste and the linear sliding structure for toothpaste extrusion. It is difficult to do and has a structure that can not be used to refill toothpaste. In addition, the above-described structure has a problem in that the replacement of the brush 4 is impossible when the brush 4 is worn using a toothbrush for a certain period of time and thus has a short lifespan.

In addition, there are a number of conventional technologies in addition to the above-described prior art, but a structure that can simultaneously solve the above-described various problems has not been proposed.

For example, portable toothbrushes such as JP 96-26583 (portable toothbrushes with writing instruments and toothpaste) and JP 95-267 (portable toothbrushes with toothpaste compartments) are simply compacted with toothpaste in one case. To store or embed toothpaste in the body and use it, the brush head can be removed and the toothpaste can be buried and reassembled.

In addition, the technology for extruding toothpaste by pressing the user's hand according to the driving source for extruding toothpaste is Utility Model Publication No. 94-6414, the technology using air tube and air tube pump is applied to Utility Model Publication No. 95-266, restoring force of compression spring. The technique used is disclosed in Utility Model Publication No. 95-265.

This prior art also has a structure that is difficult to use a proper amount of toothpaste and difficult to refill toothpaste or refill of the brush head.

Therefore, the present invention has been made in view of the problems of the prior art, the purpose of which is to build a toothpaste extruded structure, while the body can achieve a sleek functional structure, brushing or exterior design design without restriction and at the same time simple 2- To provide a toothbrush having a toothpaste built-in 2-3 disposable brush head refill that can be used semi-permanently by replacing the brush head refill with a three-time toothpaste.

Another object of the present invention is to provide a brush head having 2-3 toothpaste refills.

(Example)

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

Figure 2 is a longitudinal cross-sectional view showing a toothbrush having a toothpaste embedded 2-3 disposable brush head refill showing a toothpaste extrusion structure according to a first embodiment of the present invention, Figure 3 is a brush head refill in the toothbrush shown in Figure 2 An exploded sectional view of a type that does not have a toothpaste refill.

2 and 3, the toothbrush having a toothpaste-type brush head refill according to the present invention is divided into a brush head refill 10 and a brush head refill 10 in which the toothpaste 20 is largely divided into a toothpaste. It consists of a body (30) containing a toothpaste extrusion structure for extruding.

Brush head refill 10 is a type having toothpaste refills 14 having 2-3 toothpastes 20 embedded therein as shown in FIG. Likewise, the toothpaste 20 may be configured to be any one of the types of toothpaste 20 directly embedded therein.

When the brush head refill 10 is a toothpaste refill 14, the extrusion piston 16 is installed at the rear end of the refill so as to be movable inside the refill, and when the toothpaste refill is not embedded, the inlet of the recess 12 is not included. The extrusion piston 16 is installed in the groove so as to be movable.

In addition, the distal end portion of the toothpaste refill 14 is opened before the extrusion hole 18 is mounted to the refill, when mounted in the groove 12, the toothpaste 20 to the head portion 22 formed with the brush of the brush head refill 10 It is connected to the inner passage 24 for guiding the end, the end of the inner passage 24 is formed at least 2-3 outlets 26 toward the brush side, through which the toothpaste 20 evenly from the bottom of the brush To be discharged. The toothpaste discharging structure is the same as the brush head that does not have a toothpaste refill.

On the other hand, the body 30 forms a long barrel shape in which the tip is opened, and defines the accommodation space of the brush head refill 10 to be inserted in the tip, and at the same time, when the pusher tip 40 moves, the extrusion piston of the refill ( Guide barrier ribs 32 are formed to guide the push rod 16, and through holes 36 and 38 through which the pusher tip 40 can pass are formed in the barrier rib 32 and the rear end wall 34 of the body, respectively. It is.

One end outside the body of the pusher tip 40 is integrally connected to the cup-shaped pusher 42 which is slidable left and right along the outer circumferential surface of the body 30, and a return spring is formed in the inner space of the pusher 42. 44) is built in. In this case, the pusher tip 40 has a diameter that is smaller than the front end portion by a predetermined length, that is, the stroke distance of the pusher 42, and the diameter of the front end portion is larger than the diameter of the through hole 38 of the rear end wall 34. It is set so that the pusher tip 40 is not separated from the body 30 by the restoring force of the return spring 44. Here, the stroke distance of the pusher 42 is formed to be slightly longer than the internal length of the toothpaste refill 14 to enable use without leaving any residual toothpaste.

The brush head refill 10 may be coupled by any one of press fitting, snap coupling, or screwing when its rear end is coupled to the front end side refill receiving space 46 of the body 30. Press-fitted as shown in Figure 2 can simplify the structure.

The operation of the present invention having the above configuration will be described in detail below.

In the case of a disposable, the amount of toothpaste filled in the recess 12 or the toothpaste refill 14 of the brush head refill 10 may be about 3 g. Even when brushing three times, it is possible to embed the required amount of toothpaste in the groove 12 or the toothpaste refill 14 described above. Therefore, it is possible to select a suitable refill toothpaste 14 according to the user's needs, it is possible to prevent the phenomenon of wasting the toothpaste of the small package that is currently used once and a large amount remains. In this case, it is preferable that the rear ends of the grooves 12 and the refills 14 are covered with the pressing piston 16 with a thin sanitary packing foil or the like.

When the toothpaste 20 is press-fitted into the refill receiving space 46 of the body 30, the brush head refill 10 embedded in the recess 12 or the toothpaste refill 14 is pressed into the refill 10. The rear end, that is, the crimping piston 16 comes into contact with the front end of the pusher tip 40.

In this state, when the user compresses the pusher 42 at the rear end of the body, the spring 44 is compressed and the front end portion of the pusher tip 40 compresses the pressing piston 16 to the front. In this case, in the case of disposable use, all the toothpastes 20 are discharged from the bottom of the brush to the top through the 2-3 passages 26 through the inner passage 24 from the extruder 18 by the complete compression of the pusher 42. do.

In this case, in the case of 2-3 times, the user pushes the pusher 42 by each eye sequentially by extruding the appropriate amount of toothpaste by the marking of 1 to 3 times of the marking eyes marked on the rear end surface of the body 30. Because it can be used, even a small amount of toothpaste can be brushed a predetermined number of times.

When the pusher 42 is released, the spring 44 returns to its original position by the restoring force of the spring 44.

On the other hand, when the brush of the brush head refill 10 is not used according to the replacement and use of the toothpaste refill 14, the body 30 is partially semi-permanently used by only replacing the brush head refill 10, thereby making it impossible to refill. Compared to the disposable toothbrush, the cost of use can be greatly reduced and the waste of resources and pollution caused by the disposed plastic toothbrush can be suppressed.

Meanwhile, in the present invention, when the cover is coupled to the tip of the body 30 while covering the head as necessary at the tip of the toothbrush, hygienic storage is possible as portable.

Furthermore, by increasing the size of the brush head refill 10 described above, the toothpaste content is maximized to allow the use of a plurality of times.

As described above, in the present invention, in the toothpaste extrusion method, the extrusion piston is advanced by advancing the pusher at the rear end to extrude the toothpaste in the container to the brush head. Therefore, while the toothpaste extrusion structure is built in, the slender functional structure can be realized, so it is not restricted to brushing or exterior design design.

In addition, the brush head refill can be replaced semi-permanently, the body can be used semi-permanently, and the toothpaste refill can be replaced 2-3 times, and the brush head refill can be used for a certain period of time. Easy to use, economical and hygienic.

In the above, the present invention has been illustrated and described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and is not limited to the spirit of the present invention. Various changes and modifications can be made by those who have
