Description

  The present invention relates to a toothpaste set including a toothbrush and a tube containing toothpaste that can be attached to the toothbrush.

  A toothbrush set has been proposed in which a toothbrush and a toothpaste receiver are used as a unit, and a mechanism for delivering the toothpaste to the toothbrush.

  Patent Document 1 proposes a toothbrush in which a handle (grip portion) is a toothpaste container. The inside of the container communicates with the brush portion, and toothpaste can be pushed out to the brush portion. The structure for extruding toothpaste mainly consists of an internal part attached to the rear end side of the handle and an extruded member. The internal member includes a bolt that extends into the container. The extrusion member has a screw hole that is screwed into the bolt. When the internal member is rotated around the bolt, the pushing member is prevented from rotating with respect to the container, and therefore slides forward to push out the toothpaste.

  Cited Document 2 proposes a toothbrush in which a toothpaste-containing tube (toothpaste container) is attached to a brush part (tip portion having a brush) and this tube is covered with a body case. By moving a lever attached to the body case, the toothpaste is pushed out to the brush through the supply path.

  The toothpaste set according to the cited document 1 has a complicated structure for extruding toothpaste, as well as complicated supplementation of toothpaste. Moreover, in order to extrude the toothpaste, it was necessary to support the toothbrush with one hand and rotate the internal components attached to the rear end of the handle with the other hand.

  The toothpaste set described in the cited document 2 has a complicated structure for extruding toothpaste. The trunk case of Cited Document 2 is considered to be provided in the tube containing toothpaste because the strength of the grip portion cannot be maintained. However, since the trunk case is provided, the structure for extruding the toothpaste is complicated. In addition, it is necessary to move the lever to squeeze out the toothpaste, but for a while after replacing the tube, the lever is near the rear end of the fuselage case, so move the lever while holding the toothbrush with one hand. Was difficult. Further, if an extrusion mechanism such as a lever is not provided, it is necessary to remove the body case, squeeze the tube, and attach the body case every time it is used.

  The present invention has been made in view of the above background, and in a toothpaste set using a toothbrush and a tube containing toothpaste in an integrated manner, the toothpaste can be squeezed out while holding the toothbrush with one hand. It is an object to provide a toothpaste set that can be used.

  To achieve the above object, a toothbrush set 1 according to the present invention includes a handle portion (4) having a front end and a rear end, and a brush portion connected to the front end of the handle portion and having a brush (9) on the front surface. The toothbrush (2) comprised by (5) and the toothpaste containing tube (3), The said handle | pattern part is a notch part (10) which supports the said tube between the said front end and the said rear end. The tube has flexibility to be deformed when pressed in a state of being supported by the notch portion, and the toothpaste is delivered to the brush portion when the tube is deformed. Features.

  According to this configuration, since the handle portion supports the tube, the toothbrush is strong enough to withstand brushing without using a separate case or the like. Moreover, since the tube is exposed, the structure for squeezing the toothpaste is simple, and the user can sensuously understand that the toothpaste can be squeezed out by pressing the tube with a finger. Moreover, toothpaste can be squeezed out with one hand while holding the toothbrush.

  In the above invention, the notch portion may be formed on the front side of the handle portion.

  According to this configuration, the tube is attached to the same side as the brush. When brushing teeth, the user applies force to the surface of the toothbrush opposite to the brush to press the brush against the teeth. Therefore, even if the user's finger is attached to the tube, it is not necessary to apply a large force to the front side, and the user can brush his / her teeth so that the toothpaste does not discharge. Conversely, if necessary, the toothpaste can be discharged while brushing teeth by intentionally applying force to the tube.

  The said invention WHEREIN: When the said tube is supported by the said notch part, the latching structure which the rear end side of the bottom face of the said notch part latches the rear end side of the said tube may further be included.

  According to this configuration, since the forward movement with respect to the notch portion on the rear end side of the tube is restricted, even when the toothpaste is discharged, the rear end of the tube may be pushed even if the upper surface of the tube is pushed forward. The side can be prevented from shifting with respect to the notch.

  In the above invention, the handle portion includes two rear side walls (15, 15) that respectively extend forward from both side end portions of the rear end surface of the cutout portion, and the locking structure includes the two rear portions. Two locking projections (16, 16) extending so as to approach each other from the side lateral wall, and formed on both side portions on the rear end side of the tube so as to fit each of the locking projections Two locking recesses (42, 42, 64, 64) may be provided.

  According to this configuration, the upper end of the locking convex portion is continuous with the upper surface of the handle body through the rear lateral wall. Therefore, a portion having a height equal to or higher than that of the locking projection exists in the vicinity of the locking projection, so that even if a finger touches the locking projection and a force is applied, the force is distributed in the vicinity. Thus, the pressure applied to the finger from the locking projection or the like is reduced, and there is little risk of damaging or hurting the finger.

  In the above invention, the handle portion includes an inlet (19, 61) that communicates with the inside of the tube when the tube is supported by the notch portion, and the brush portion is formed on the front side. A discharge port (32) communicating with the injection port may be provided, and the injection port may be configured to protrude rearward from the front end of the notch.

  According to this structure, the refractive location of the toothpaste supply path can be reduced, and the toothpaste can be discharged smoothly.

  In the above invention, the back side wall of the tube may be formed of a material harder than the front side wall. Moreover, you may comprise the back side wall of the said tube so that the rib extended in the front-back direction may be included.

  According to this configuration, it is possible to reduce the possibility that the front end side of the tube is displaced rearward with respect to the cutout portion and the tube is buckled in the front-rear direction.Therefore, the tube may be detached from the inlet provided at the front end of the cutout portion. Can be reduced.

  In the above invention, the inlet may be configured to protrude upward from the front end side of the bottom surface of the notch.

  According to this configuration, since the injection port engages with the front end side of the tube from below, it is possible to prevent the front end side of the tube from shifting in the front-rear direction and the left-right direction with respect to the notch portion.

  According to the present invention, since the handle portion supports the tube, the toothbrush has strength enough to withstand brushing without using a separate trunk case or the like. In addition, since the tube is exposed, the structure for squeezing out the toothpaste is simple, and the user can sensuously understand that the toothpaste can be squeezed out by pressing the tube with his finger, while holding the toothbrush with one hand. Toothpaste can be squeezed out.

On the front side of the handle body 6, a notch 10 is provided from near the center in the front-rear direction of the handle body 6 to the front side. The notch 10 is defined by a bottom wall 11, a front wall 12, a rear wall 13, front side walls 14 and 14, rear side walls 15 and 15 having locking projections 16, and a front upper wall 17. In order to supplement the strength of the notch 10, a rib (not shown) extending in the front-rear direction may be provided on one or both of the front side and the back side of the notch 10.

  The bottom surface of the notch 10 defined by the bottom wall 11 is substantially parallel to the back surface of the handle body 6 and the front surface of the handle body 6 other than the notch 10 (upper surface of the handle body 6). The front surface of the notch 10 defined by the front wall 12 and the rear surface of the notch 10 defined by the rear wall 13 are each orthogonal to the longitudinal axis.

  The front side walls 14, 14 respectively extend rearward from the left and right sides of the front wall 12 along the bottom surface of the notch 10, the inner surfaces facing each other are parallel, and the outer surfaces are the side surfaces of the handle body 6. One plane is formed. The upper ends of the front lateral walls 14, 14 extend rearward so as to form one plane with the upper surface of the handle portion 4, and then incline downward as they extend rearward. That is, the front side walls 14 and 14 are provided on the left and right sides of the handle body 6 so as to face each other, and each has a trapezoidal shape in a side view, and the upper and lower bases are respectively the upper surface and the cut surface of the handle body 6. It coincides with the bottom surface of the notch portion 10, one side coincides with the front surface of the notch portion 10, and the remaining one side is inclined downward.

  The rear lateral walls 15, 15 respectively extend forward from the left and right sides of the rear wall 13 along the bottom surface of the notch 10, the inner surfaces facing each other are parallel, and the outer surfaces are the side surfaces of the handle body 6. And form one plane. The upper ends of the rear lateral walls 15, 15 extend forward so as to form one plane with the upper surface of the handle body 6, and then incline downward as they extend forward. That is, the rear side walls 15 and 15 are provided on the left and right sides of the handle body 6 so as to be opposed to each other, each of which has a trapezoidal shape when viewed from the side, and the upper and lower bases respectively It coincides with the bottom surface of the notch 10, one side coincides with the rear surface of the notch 10, and the remaining one is inclined downward.

  The locking protrusions 16 and 16 are rectangular parallelepiped protrusions that protrude from the inner surfaces of the rear lateral walls 15 and 15 so as to approach each other. The upper surface coincides with the upper surface of the handle portion 4 other than the notch portion 10 and the lower surface thereof coincides with the bottom surface of the notch portion 10. In other words, the locking projections 16, 16 protrude from the bottom surface of the notch 10 to the top surface of the handle body 6 along the inner surface of the rear lateral wall 15, 15. There is a gap between the locking projections 16 and 16 and the rear wall 13.

  The front upper wall 17 is formed between the upper ends of the front side walls 14 and 14 such that the upper surface thereof coincides with the upper surface of the handle portion 4 and the lower surface thereof faces the bottom surface of the notch portion. The front upper wall 17, together with the front side of the bottom wall 11, the front side of the front wall 11 and the front side walls 14, 14, defines a tube front end receiving part 18 that is recessed forward in the notch 10. The receiving portion 18 receives the front end portion of the tube 3. The shape of the receiving portion 18 may be changed so that the receiving portion 18 fits the front end portion of the tube 3.

  The injection port 19 protrudes from the center of the front surface of the notch portion 10 in the left-right direction toward the rear. The injection port 19 is a hollow member such as a cylinder and may be integrally formed with the toothbrush 2 or may be attached to the notch 10 as a separate body made of resin or metal.

  The connecting end 7 of the handle 4 is located on the front end side of the handle 4 and connects the handle main body 6 and the brush 5. The shape of the connecting end portion 7 is axisymmetric with respect to the central axis in the front-rear direction when viewed from the front. The connecting end portion 7 is smoothly continuous with the handle portion main body 6, and the rear end side of the connecting end portion 7, that is, the side connecting to the handle portion main body 6 has a lateral width from the rear end side to the front. is decreasing. On the front end side of the connecting end portion 7, the width in the left-right direction is a substantially constant width equal to or smaller than the width in the left-right direction of the brush portion 5.

  The brush part 5 is connected to the front end of the connecting end part 7 of the handle part 4, and has a plurality of hair bundles 8 and a flocked base part 31 on which the hair bundles 8 are implanted. The hair bundle 8 is a bundle of bristles (natural bristles) made of a resin such as nylon or a natural material. The flocked base 31 has a rounded rectangular shape or an elliptical shape when viewed from the front. A discharge port 32 communicating with the injection port 19 of the handle portion 4 is formed in the flocked base portion 31. In the present embodiment, the discharge port 32 is formed in the center of the flocked base 31 so that the toothpaste is discharged in the center of the brush 9, and the hair bundle 8 is not planted in the discharge port 32. The position where the discharge port 32 is formed may be changed to a position close to the brush 9. In addition, a discharge pipe (not shown) is attached to the discharge port 32, and the height of the upper end thereof is made about the same as the height of the brush 9 to about half the height of the brush 9, so that toothpaste can be easily discharged onto the upper surface of the brush. May be. If the hardness of the discharge pipe is less than or equal to that of the brush 9, it is preferable that the height of the upper end is the same as the height of the brush 9 or about 10% to 20% lower. If it is harder than the brush 9, it is preferable to further reduce the height of the discharge pipe so that the upper end of the discharge pipe does not hit the teeth during brushing.

  A supply pipe 36 that communicates the injection port 19 of the handle 4 and the discharge port 32 of the brush 5 is formed from the handle body 6 to the brush 5. The supply pipe 36 is formed in a substantially linear shape in the front-rear direction, and is refracted at an angle of about 90 ° so as to face the discharge port 32 on the front end side. The supply pipe 36 is formed at the same time when the main part of the toothbrush 2 other than the brush 9 is injection-molded. For example, a portion extending in the front-rear direction in the supply pipe 36 is formed by forming a through hole extending from the front surface of the notch 10 to the front end of the flocked base 31 and then closing the distal end side of the flocked base 31. May be. Moreover, after forming the groove | channel from the front surface of the notch part 10 to the discharge outlet 32 formed in the flock base 31 in the back surface of the toothbrush 2, you may form by covering this groove | channel. Further, the main part of the toothbrush 2 other than the brush may be composed of two pieces with the rear end of the supply pipe 36 as a boundary, and each may be joined together after injection molding.

  The tube 3 has a circular cylindrical shape with a front end or a long oval shape in the left-right direction, and a straight cylindrical shape with a rear end extending in the left-right direction. The tube 3 is filled with toothpaste. The front (upper surface) side of the side wall 41 of the tube 3 has flexibility to be deformed when pressed, and the rear (lower surface) side is harder than the front side so as not to be deformed in the front-rear direction. For example, by using a material harder than the front side on the back side, making the back side thicker than the front side, or attaching a rib (not shown) extending in the front-rear direction to the back side, Can be substantially hardened. Moreover, it is preferable that the display which can distinguish a front surface and a back surface is made | formed. The tube 3 can be made of a resin such as polyethylene, aluminum foil, or the like, and the side wall 41 of the tube 3 may have a laminated structure of a plurality of materials.

  The rear end side of the tube 3 is formed by overlapping (in the case of a resin) or bending (in the case of an aluminum foil) with the upper and lower sides of the side wall 41 being overlapped. Therefore, the rear end side of the tube 3 has a flat plate shape. On the rear end side of the flat tube 3, two locking recesses 42 and 42 are formed toward the central axis in the front-rear direction so as to approach each other from the left and right ends. When the tube 3 is supported by the notch 10 of the handle 4, the locking recesses 42 and 42 are fitted to the locking protrusion 16 of the notch 10, and the rear end side of the tube 3 is against the toothbrush. Thus, movement in the front-rear direction and the left-right direction is restricted.

  In the center of the front end of the tube 3, a hole 43 into which the injection port 19 of the handle 4 is inserted is provided, and the hole 43 is covered with a seal 44.

  As the toothpaste, a toothpaste or a semi-solid material such as a gel body is used.

  When the toothbrush set 1 according to the first embodiment is used, the tube 3 is attached to the toothbrush 2 at the first use. First, the front end side of the tube 3 inclined downward is inserted into the tube front end receiving portion 18 of the handle portion 4 so that the injection port 19 of the handle portion 4 is inserted into the hole 44 of the tube 3, and then locked. The rear end side of the tube 3 is lowered to the notch portion 10 so that the convex portion 16 fits into the locking concave portion 42. At this time, the seal 44 is removed. When the seal 44 is made of a material that can be broken by the force when the tube 3 is inserted, the seal 44 does not have to be removed. Thus, since the tube 3 can be attached to the handle 4 of the toothbrush 2 in a cartridge manner and can be removed by the reverse operation, the handling is easy.

  When putting out toothpaste, the side wall on the front side of the tube 3 is pushed with a finger. Then, since the bottom wall 11 of the notch 10 is harder than the side wall of the tube 3, the side wall 41 of the tube 3 is greatly deformed compared to the bottom wall 11 and the volume inside the tube 3 is reduced. Then, it is pushed out to the injection port 19, passes through the supply pipe 36, is discharged from the discharge port 32, and adheres to the brush 9. At this time, the rear end side of the tube 3 and the rear end side of the notch 10 are arranged in the front-rear direction with respect to each other by the locking structure formed by the locking projections 16, 16 and the locking recesses 42, 42. Movement is regulated. Therefore, even if the tube 3 is pushed so that the toothpaste is pushed forward, the tube 3 does not shift with respect to the notch 10. Further, the upper ends of the locking projections 16 and 16 are continuous at the same height as the upper surface of the handle body 6 via the rear lateral walls 15 and 15, so that a finger touches this portion and a force is applied. However, since the force is dispersed and the pressure applied to the finger from the locking projections 16 and 16 is small, there is little possibility of damaging or hurting the finger.

  Moreover, since the back side of the side wall of the tube 3 is harder than the front side, the tube 3 can be prevented from buckling, that is, the front end side of the tube 3 can be prevented from moving backward with respect to the notch portion 10. The hole 43 of the tube 3 can be prevented from coming off from the inlet of the handle 4.

  Further, the lateral displacement of the tube 3 with respect to the notch 10 is prevented by the front lateral walls 14, 14 and the rear lateral walls 15, 15, and the inlet 19 inserted into the tube 3 is formed in the peripheral wall of the hole 44. It is also prevented by engaging.

  Further, the vertical displacement of the tube 3 with respect to the notch 10 is prevented by the front upper wall 17 and the injection port 19 inserted in the tube 3, and the user's finger is being brushed while brushing teeth. Can be prevented by attaching to the tube 3.

  While brushing teeth, the user applies a force mainly from the back side of the toothbrush 2 to press the brush 9 against the teeth. Therefore, it is not necessary to apply a large force to the tube 3 attached to the front side of the toothbrush 2. Therefore, the user can adjust the force holding the toothbrush so that the toothpaste is not squeezed out while brushing the teeth. Conversely, if you feel that the amount of toothpaste is insufficient while brushing your teeth, you can squeeze out the toothpaste while brushing your teeth by pushing the front side of the side wall 41 of the tube 3 with your finger based on the intention of the user. .

  As described above, the toothpaste set according to the present invention is easy to use, can be intuitively understood, and can be used a plurality of times, and thus is suitable for provision to users of accommodation facilities, for example. For example, a user of one night is assumed to brush his teeth on the first night and on the morning of the next day, but since the toothbrush 2 and the tube 3 are united at the first use, only two toothpastes are used. Even a small tube 3 that is not contained is less likely to be lost. In addition, the amount of waste can be reduced compared to a one-time disposable toothbrush in which toothpaste is pre-applied to the brush. Also, if you notice that the amount of toothpaste is not enough while you are brushing your teeth, even if you do not know the amount of toothpaste you use at home, you can brush your teeth. Can be increased while.

<Modification of First Embodiment>
Next, a modification of the first embodiment will be described (not shown). In the first modified example, there is no supply pipe 36 formed inside the toothbrush 2, and a supply pipe formed separately from the toothbrush body is attached to the front surface of the toothbrush body so as to extend in the front-rear direction. . In this case, the inlet 19 and the outlet 32 of the first embodiment are the rear end and the front end of the supply pipe. The rear end of the supply pipe protrudes rearward from the front surface of the notch, and the front end of the supply pipe is disposed in the vicinity of the rear end of the brush. Further, there is no portion corresponding to the front upper wall 18 of the first embodiment. You may form the groove | channel which receives or fits the lower side or the whole of a supply pipe | tube in the front side of a toothbrush. According to this structure, manufacture of a toothbrush becomes easy.

  The second modification (not shown) does not have the front upper wall 17, the injection port 19, the discharge port 32, and the supply pipe 36 of the first embodiment, and the shape of the front end side of the tube is different from that of the first embodiment. The tube includes a rear end side portion supported by the notch portion and a front end side portion extending from the front surface of the notch portion to the vicinity of the rear end of the brush. The front end portion is tubular, and the toothpaste discharge port is provided on the front surface or the front surface near the front end. You may form the groove | channel which receives or fits the lower side or the whole front-end side part of a tube in the front side of a toothbrush. According to this structure, manufacture of a toothbrush becomes easy.

Second Embodiment
Next, a toothbrush set according to a second embodiment of the present invention will be described with reference to FIG. In the description, the description of the configuration common to the first embodiment is omitted and the same reference numeral is given. Even in the configuration having parts different from those of the first embodiment, description of common parts is omitted.
