Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a dental pasteboard book in which a large number of disposable pasteboards for kneading various dental cements and impression materials are laminated.
[0002]
[Background]
Most of the materials used as various dental cements, impression materials, core fillers, restoration materials, etc., are two or more different drugs such as powder and liquid, liquid and liquid, etc. A polymer formed by kneading with a spatula (or spatula). Due to the nature of such a chemical component, a flat table having water resistance and chemical resistance is used as a table used for kneading. Conventionally, glass plates have been used as a table for kneading, but after use, the surface of the cement will begin to harden if the surface is not quickly wiped off. It took time and effort to remove the polymer. For this reason, disposable pasteboard has been widely used in recent years.
[0003]
The above-mentioned paperboard is usually laminated on a backing sheet with a large number of substantially rectangular shapes with water resistance and chemical resistance, and the end faces are attached with adhesive, etc., and peeled off one by one like a notepad It is in a state where it is possible to bind. For example, in Patent Document 1, for a large number of square shaped kneaded papers superimposed on a mount, two opposing sides are used as connecting sides and the remaining two opposing sides are formed as separating sides, and one connecting side is provided. In addition, there is described a dental Japanese paper spelling in which a corner separation side is formed by cutting off a corner portion where a separation side adjacent thereto intersects. According to this, it is possible to distinguish between the arrangement of the connecting edge and the separating edge by using the corner separating edge as a mark, and at the time of kneading work, it is possible to always select a fixed holding position and to peel the kneaded paper after use. Can be easily performed.

[Problems to be solved by the invention]
However, in the background art as described above, only the end faces of the two opposite sides are bonded, so in order to prevent deformation and bending of the kneaded paper board during the kneading operation, a desk or the like is sandwiched between the upper and lower separation sides. It needs to be pressed against the table, and it is not possible to hold any position. In addition, since the kneading work is generally performed by a rotary motion such as a spatula or a motion in the vertical and horizontal directions, bonding of only the two end faces causes the upper kneaded paper board to shift during the work, resulting in wrinkles. There is a risk that the kneading may not be performed smoothly, and the kneading board may be peeled off during the work. In addition, since the amount of chemicals to be polymerized on the kneading paperboard is always measured at a nominal amount, if a person other than an expert performs the work, it is completely polymerized during kneading and cannot be used. It may not be possible to do it promptly.
[0006]
The present invention focuses on the above points, and the purpose of the present invention is to smoothly knead a plurality of chemicals without causing the upper-layer kneading paper to slip, and to quickly peel off the kneading paper after use. It is to provide a dental pasteboard book. Another object is to provide a dental board that can knead a plurality of drugs with an appropriate formulation.
[0007]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the dental pasteboard book according to the present invention is a dental paste formed in a laminate by superimposing a plurality of pasteboards having water resistance and chemical resistance on a mount so as to be peelable. a paperboard book, the number of kneading paperboard, a pair of opposite sides are formed in different trapezoidal parallel and length Rutotomoni, is concentrically or concentric elliptical scale on one side of the paper is formed, the Only the end face of the parallel opposite side of the laminated board is covered with an adhesive layer so that the multiple paper boards can be peeled off, and one side of the parallel opposite side bonded by the adhesive layer and the other pair A corner where one side of the non-adhesive opposite side intersects is cut off to form a cut-out portion for peeling the pasteboard one by one from the laminate.
[0009]
Further, the material of the plurality of pasteboards may be transparent or semi-transparent, and the concentric or concentric elliptical scale may be formed on the back side of the pasteboard .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
<Embodiment 1> Hereinafter, embodiments of the present invention will be described in detail. First, Embodiment 1 will be described with reference to FIG. 1A is a front view of this embodiment, FIG. 1B is an end view of FIG. 1A viewed from the direction of arrow F1 in FIG. 1, and FIG. 1C is a diagram showing a use state of this embodiment. As shown in the figure, a dental pasteboard book 10 (hereinafter referred to as “kinderboard book”) of the present embodiment has a substantially square shape, and has the same shape and dimensions as the mount 12 on the mount 12. It is in the form of a laminate in which a large number of pasteboards 14 are stacked. The upper, lower, left and right end surfaces 15, 17, 19, and 21 are provided with adhesive layers 16, 18, 20, and 22 on almost the entire circumference except for the corner 24 on the lower left side of the figure. Thus, a large number of paperboards 14 are bonded to each other at their end faces so that they can be separated one by one.
[0011]
As the mount 12, for example, relatively strong cardboard is used from the viewpoint of preventing deformation and bending during the kneading operation. Further, an anti-slip sheet layer such as rubber may be provided on the back surface so that the entire kneading board book 10 does not slip on a work table such as a desk during the kneading operation. The kneading board 14 may be any material that does not allow cement powder or kneading liquid used in the kneading operation to permeate or react with the back, and various known materials such as Japanese paper and paper. In addition, synthetic paper made mainly of polypropylene, polyvinyl chloride, polyester, polyethylene, polystyrene resin, or the like is used. The adhesive layers 16, 18, 20, and 22 are not particularly limited as long as they can peel the kneaded paperboard 14 one by one. For example, various known adhesives such as a hot melt adhesive can be used. The paperboard 14 and the mount 12 are bound together by the adhesive. If necessary, a cover having the same shape and the same dimensions as those of the mount 12 and the pasteboard 14 may be appropriately provided on the uppermost pasteboard 14A.
[0012]
Next, the operation of this embodiment will be described. The operator 30 places the above-described kneading paper book 10 on a work table 28 such as a desk and mixes two kinds of chemicals 34 and 36 (for example, cement powder and kneading) on the surface of the uppermost kneading paper 14A. Take the desired amount of Japanese liquid, etc., hold the upper and lower corners of the left hand with the thumb and forefinger of one hand (left hand in the example shown), and knead the drugs 34 and 36 using the spatula 38 with the other hand. The When the polymerization proceeds to an appropriate state by kneading, the produced polymer is used for dental treatment or treatment. After use, as shown in FIG. 1 (B), when the uppermost kneading paperboard 14A is picked at the corner 24 and rolled up and peeled off from the adhesive layers 16, 18, 20 and 22, the next kneading paperboard 14B is It will be ready for use. By repeating the above operation, the paperboards 14 can be used sequentially one by one.
[0013]
Thus, according to the present embodiment, almost the entire periphery of the end face is covered with the adhesive layer except for one corner 24 of the laminate of the pasteboard 14. Thus, regardless of the arrangement of the paperboard book 10, the kneading work can be carried out while holding an arbitrary position, and after use, the paperboard 14 can be picked at the corner 24 and quickly peeled off. . Further, even when kneading is performed by movement in the up / down / left / right direction or circular movement, the upper kneading paperboard 14 can be smoothly operated without being displaced or peeled off.
[0014]
<Embodiment 2> Next, Embodiment 2 of the present invention will be described with reference to FIG. FIG. 2A is a front view of this embodiment. The pasteboard book 40 of the present embodiment is obtained by superimposing a large number of pasteboards 44 on a mount (not shown). A pair of end faces 45 and 47 of the pasteboard 44 are parallel and have different lengths. It has a trapezoidal shape. Of the other set of end surfaces, the left end surface 50 in the drawing is inclined with respect to the upper and lower end surfaces 45 and 47, and the right end surface 52 is orthogonal to the upper and lower end surfaces 45 and 47. . That is, the left corner portion 56 of the lower end surface 47 has a shape protruding toward the left side. In this embodiment, unlike the above-described embodiment, the adhesive layers 46 and 48 are provided only on the upper and lower end surfaces 45 and 47, and the left and right end surfaces 50 and 52 are in an unbonded state. Further, a corner where the upper end surface 45 and the right end surface 52 provided with the adhesive layer 46 intersect is cut off, and a cut-out portion 54 for peeling the pasteboard 44 one by one is formed.
[0015]
The operation of the present embodiment will be described. First, a pasteboard book 40 is placed on the work table 28, and a plurality of desired drugs are weighed on the surface of the topmost pasteboard 44 and kneaded with a spatula. At this time, if the lower end surface 47 of the paperboard book 40 is arranged so as to face the worker 30 side, the thumb of the left hand of the operator 30 presses the lower end surface 47 side, and the index finger is attached so that the left end surface 50 is inclined. At the same time, the vicinity of the base of the thumb can press the corner portion 56 protruding in a substantially triangular shape. For this reason, even if the adhesive layers 46 and 48 are provided only on the upper and lower end surfaces 45 and 47, the work is smoothly performed without the kneading board book 40 being displaced during the kneading work. When the work is completed, one sheet of the uppermost pasteboard 44 is peeled off from the cut-out portion 54. As described above, according to the present embodiment, since the entire board board 40 is substantially trapezoidal and easy to press, stable work can be performed.
[0016]
FIG. 2B shows another example of this embodiment. The entire board 60 of this example is also substantially trapezoidal, but not only the upper and lower end surfaces, but the entire upper, lower, left, and right end surfaces as in the first embodiment described above are adhesive layers 66, 68, 70, 72 is covered, and only the corner 74 where the lower end surface and the left end surface are in contact with each other is in an uncovered state. The operation and effect of this example are basically the same as those of the first embodiment described above, but since it is formed in a substantially trapezoidal shape, it is also possible to obtain an effect of being easily pressed during the kneading operation.
[0017]
<Third Embodiment> Next, a third embodiment of the present invention will be described with reference to FIG .
The paperboard 80 shown in FIG. 3 (A) is generally rectangular as in the first embodiment described above, and almost the entire end surface is covered with an adhesive layer except for one corner, Further, a concentric scale 84 is provided on the surface of the kneaded paper board 82 with the substantially center of the kneaded paper board 82 as the center. Usually, the drug to be kneaded on the pasteboard is weighed by a scale, but by providing a concentric scale as in the present embodiment, for example, the hardness (or viscosity) of the drug 88 extruded from the tube 86. By taking into account, the approximate amount can be determined from the spread of the drug in the center of the concentric circle and the size at that time.
[0018]
As described above, according to the present embodiment, it is possible to knead the medicine with an appropriate blend regardless of the operator 30. In FIG. 3A, concentric scales are provided, but on the surface of the substantially trapezoidal pasteboard 92 similar to that of the second embodiment, as in the pasteboard 90 shown in FIG. A concentric elliptical scale 94 may be provided. In order to avoid mixing the scale marking ink into the medicine, the pasteboard may be transparent or translucent, and a scale may be provided on the back side of the pasteboard and the medicine may be kneaded on the front side.
[0019]
Other Embodiments There are many embodiments of the present invention, and various modifications can be made based on the above disclosure. For example, the following are included.
(1) The shape, size, material, and type of medicine shown in the above embodiment are all examples, and can be arbitrarily changed as necessary. For example, in the second embodiment, only the left end surface 50 is inclined with respect to the upper and lower end surfaces 45 and 47. However, by forming the right end surface 52 to be inclined, either the left or right hand is dominant. Regardless of this, kneading can be performed smoothly. Further, the shape is not necessarily limited to a trapezoid, and any shape may be used as long as it is an acute angle shape that can be pressed along the open index finger and thumb.
[0020]
(2) You may make it combine the said form. For example, in the third embodiment shown in FIG. 3A, only the substantially concentric scale 84 is provided on one sheet of paperboard 82, but the concentric elliptical scale shown in FIG. 3B. By providing 94 on the same pasteboard, a plurality of types of medicines can be weighed more easily. Moreover, in the said form 3, although the scales 84 and 94 were provided on the kneading board of the structure similar to the said form 1 or 2, other various kneading board papers were used, and the said scales 84 and 94 were formed on it. It does not prevent it from being provided.
[0021]
【The invention's effect】
As described above, according to the invention according to claim 1, a pair of opposite sides are formed in different trapezoidal parallel and length Rutotomoni, it is concentrically or concentric elliptical scale on one side of the paper forming Only the end faces of the parallel opposite sides of the laminated board made of the laminated body are covered with an adhesive layer so that a large number of pasteboards are peelably adhered, and one side of the parallel opposite sides adhered by the adhesive layer and the other By cutting off a corner where one side of the opposite non-adhesive side of the set intersects, and forming a cut-out portion for peeling the pasteboard one by one from the laminate, the entire laminate-like pasteboard book Because it is easy to press as a trapezoidal shape, even if an adhesive layer is provided only on the opposite end face of the laminated pasteboard, the pasteboard book does not shift during kneading of a plurality of chemicals, Stable work can be performed smoothly. When the drug kneading operation is completed, the uppermost board board can be easily peeled off one by one from the cut-off portion. Further, the one surface of the front SL multiple kneading paperboard, by forming the concentric or concentric elliptical scale, for example, by taking into account the hardness of the drug is extruded from the tube (or viscosity), concentric or The approximate amount can be determined from the spread of the drug at the center of the concentric elliptical scale and the size at that time. Therefore, the medicine can be kneaded with an appropriate blend regardless of the operator.
Furthermore, according to the invention of claim 2 , the material of the plurality of paperboards is made transparent or translucent, and the concentric or concentric ellipse scales are formed on the back side of the paperboard. It is possible to prevent the ink forming the scale from being mixed into the medicine by kneading the medicine on the surface side of the paperboard.
