Description

  The present invention relates to a dental instrument storage case for storing a dental grinding tool or the like.

  Dental instruments attached to a handpiece such as dental grinders are stored in a special case and sold or transported. And, when used for treatment, it is taken out from the storage case and attached to the handpiece. However, such a dental grinding tool or the like is small, so it is necessary to pick it up with a fingertip and perform work such as attachment. And, since the dental instrument is stored so as not to move in the storage case, picking and removing it from the storage case is a troublesome operation.

  Here, in the storage case described in Patent Document 1 and Patent Document 2, in order to make it easy to take out the device, a mechanism capable of changing the holding angle of the dental device is provided. FIG. 4 and FIG. 5 are diagrams showing a storage case of a conventional dental instrument.

  A storage case 100 as shown in FIGS. 4 and 5 has a storage portion 101 and a lid portion 102. When the lid portion 102 is opened, the angle of the storage portion 101 changes, and the dental instrument 50 is exposed. It is a mechanism that makes it easy to take out. At this time, the dental instrument 50 can be easily taken out, but since several dental instruments 50 are stored side by side, a nail may hit the next instrument when taking it out, and the nail is scratched. It may cause problems such as sticking, hooking and dropping the next device. In particular, since many dental assistants are women, it is apt to be particularly disliked to have their nails scratched.

It is a figure which shows the dental instrument storage case of this invention, Comprising: (a) is a top view, (b) is a top view of the state which accommodated the dental instrument, (c) is a perspective view. It is sectional drawing which accommodated the dental instrument in the recessed part for accommodating, and the upright hole. It is sectional drawing explaining the accommodation state of a dental instrument, Comprising: (a) is the state hold | maintained horizontally, (b) is the state which lifted the working part and stood up diagonally. It is a figure which shows the storage case of the conventional dental instrument. It is a figure which shows the storage case of the conventional dental instrument.

  Hereinafter, embodiments of the present invention will be described with reference to the attached drawings.

  FIG. 1 is a view showing a dental instrument storage case of the present invention, wherein (a) is a plan view, (b) is a plan view in a state where the dental instrument is accommodated, and (c) is a perspective view. The dental instrument storage case 10 accommodates a plurality of dental instruments 50 in parallel, and is resin-molded. The rightmost dental instrument 50 in FIG. 1 (b) is in a state of being held upright in the upright hole 40.

  The dental instrument storage case 10 includes a main body 11 having a portion for housing the dental instrument 50, and a lid 12 having a pressing portion 13 for pressing the dental instrument 50 from the upper side. It is structured to be able to open and close the main body portion 11. Although not shown, the lid 12 may be slid relative to the main body 11 for opening and closing. Further, the main body 11 has a storage recess 20 for fitting and storing the dental instrument 50 horizontally, and a fixing groove 30 for obliquely fixing the shaft end 51 a of the dental instrument 50. Furthermore, the floor 11a of the main body 11 may be provided with an upright hole 40 for holding the dental instrument 50 upright.

  The storage recess 20 fits the shaft 51 of the dental instrument 50 and accommodates the dental instrument 50 in a substantially horizontal state. In addition, although the dental instrument 50 is based on a dental grinding tool having the working portion 52 and the shaft portion 51 attached to the handpiece, the shaft portion 51 is fitted and stored in this manner except for the dental grinding tool. Anything that can be done is acceptable. Also, the storage recess 20 may be structured to be fitted and stored in one place with respect to one dental instrument 50, but as shown in FIG. 1, the storage recess 20a on the axial end side of the shaft 51 is used The structure of fitting at a plurality of places, such as two places of the storage recess 20b on the part side, has the advantage of being able to store horizontally in a more stable state. Although not illustrated, another storage recess may be provided between the storage recess 20 a on the shaft end side and the storage recess 20 b on the working unit side.

  The fixing groove 30 is a groove having a width that can be pinched and fixed when pressing the shaft end 51a of the dental instrument 50 toward the floor surface 11a of the dental instrument storage case 10, that is, the same as the diameter of the shaft 51, Alternatively, the groove may be slightly narrower than the diameter. The length of the fixing groove 30 is preferably 4 mm or more because it is preferable that the length of the tip of the finger easily enters. On the other hand, in order to make it easy to set the lifting angle of the working unit 52 to a certain value or more, it is preferable to press down within about 1/3 of the original side of the total length of the dental instrument 50. It is desirable to set the upper limit. In the present embodiment, a long size of the working unit 52 is ensured by widely securing a space for housing the working unit 52 on the floor surface 11a (a portion on the working unit 52 side bordering the storage recess 20 where the shaft 51 is fitted). The length of the fixing groove 30 is set so as to correspond to the dental instrument 50 of the above and to correspond to the short size dental instrument 50 of the shaft 51. Therefore, although about 4 mm-7 mm are preferable, it does not limit to these. Also, the direction of the groove is in the same direction as the axial direction of the dental instrument 50. Here, when the fitting position of the storage recess 20 is moved back and forth on the shaft 51 depending on the length of the shaft 51 and the length of the working portion 52 of the dental instrument 50, when the shaft end 51a is pushed down The position where the shaft end 51a reaches the floor of the dental instrument storage case 10 also shifts back and forth. However, since this shift always occurs only in the axial direction of the dental instrument 50, if the direction of the fixing groove 30 is the same as the axial direction of the dental instrument 50, the shift is in the case of fixing the shaft end 51a. Will not be a problem.

  The upright hole 40 is a hole provided on the floor surface 11 a of the dental instrument storage case 10, and is for inserting the shaft end 51 a of the dental instrument 50 and holding it upright. That is, the diameter of the upright hole 40 should be the diameter at which the shaft end 51 a just fits, or a diameter slightly larger than that of the shaft 51. If the diameter is too small, it will not fit, and if it is too large, it will fall, so long as the hole can be used to hold the dental instrument 50 upright. The upright hole 40 may be a ring-shaped convex portion provided on the floor 11a, or may be a hole formed by digging the floor 11a. The position of the upright hole 40 may be between the accommodation recess 20a on the shaft end side and the accommodation recess 20b on the working part side as shown in FIG. It may be anywhere on the floor surface 11 a of the device storage case 10.

  FIG. 2: is the figure which accommodated the dental instrument in the recessed part for accommodating, and the upright hole, and is AA sectional drawing of FIG.1 (b). The rightmost storage recess 20 in FIG. 2 shows a state in which the shaft 51 is placed and held on the entrance portion of the storage recess 20 immediately before the dental instrument 50 is fitted. The accommodation recess 20 has a structure in which the shaft 51 is pushed from the inlet portion slightly smaller than the diameter of the shaft 51 of the dental instrument 50 toward the floor surface 11 a (in the direction of the arrow) and fitted. The cross section of the recess of the working recess 20 is substantially the same cross section as the cross section of the shaft 51, and the dental instrument 50 is held horizontally in the fitted state (from the left in FIG. 2) , Third and fourth storage recesses 20). Note that this fitting and storage may be one in which the dental instrument 50 is completely fixed or one in which there is a margin for allowing a slight movement. Since the dental instrument 50 does not have to move around in the case when transporting the dental instrument storage case 10, the pressing section 13 provided on the lid 12 is configured to press the dental instrument 50 from above. If it is stored, there is no particular problem even in the structure of fitting and storing with allowance. Conversely, if the dental instrument 50 can be completely fixed only by the storage recess 20, the pressing portion 13 may be unnecessary.

  The rightmost dental instrument 50 in FIG. 2 shows the state where the axial end 51 a is inserted into the upright hole 40 and held upright. As described above, the upright hole 40 is a hole provided on the floor surface 11a and having a diameter substantially the same as the diameter of the shaft end 51a. The upright holes 40 are used as preparation for use or when temporarily placing the dental instrument 50 that has been used once.

  FIG. 3 is a cross-sectional view for explaining the stored state of the dental instrument, in which (a) is in a horizontally held state, and (b) is in a state in which the working portion is lifted and erected. In the state where the dental instrument 50 is held horizontally in the storage recess 20, it is troublesome to take out the dental instrument 50. Therefore, it is easy to pick only the dental instrument 50 to be used and prepare for use. Good. Here, by pressing the vicinity of the shaft end 51a of the dental instrument 50 toward the floor surface 11a of the dental instrument storage case 10 (in the direction of the arrow), the fitting of the storage recess 20b on the working unit side is released. The working portion 52 of the dental instrument 50 is lifted with the storage recess 20 a on the shaft end side as a fulcrum. At this time, since the fitting of the storage concave portion 20a on the shaft end side does not completely come off, if the shaft end 51a is sandwiched in the fixing groove 30, it can be fixed in a diagonally standing state.

  In addition, in order to stand up like this, since it is sufficient to push down the shaft end 51 a with a fingertip, it is possible to easily stand only the dental instrument 50 to be used. Moreover, after taking out the dental instrument 50 from the state which stood up diagonally in this way, the dental instrument 50 can be vertically stood in the upright hole 40, and it is possible to prepare only the dental instrument 50 to be used more easily. .
