Background technique

Tablet medicine is a common oral medicine in the medical field. The so-called tablet is a wafer-shaped or hetero-shaped preparation which is processed by a specific molding process after the medicine and the auxiliary material are uniformly mixed, and has the advantages of accurate dosage, convenient carrying and transportation.

For tablets, ordinary people can take it normally. However, for patients with difficulty in swallowing, or for special groups such as the elderly and children who cannot swallow whole grains, it is often necessary to grind the tablets into powdered powder with liquid, which requires grinding. The abrasive device of the tablet.

Existing abrasive devices usually use a shock, hammer, etc. to smash the tablets. This method usually exerts a large force, which increases the burden on medical personnel and brings noise, which is not suitable for a quiet medical environment. Another type of grinding device uses a lever structure to crush a tablet, and places the tablet in the splint. The force is applied by the hand piece. The grinding device using the lever structure cannot uniformly apply force during operation, and is easily applied by an excessive moment. Causing a stuck phenomenon can also cause unnecessary noise.

Compared with the above two types, the rotary abrasive device is more suitable for a quiet medical environment, but the existing rotary abrasive device is used to grind the tablet by a simple rotary pressing force, usually because the tablet is hard during the application of the force.

Figure 3 is an exploded view of the three-dimensional applicator of the present invention. Figure 4 is a cross-sectional view showing the exploded state of the three-dimensional applicator of the present invention. Figure 5 is a plan view of the pressure-retaining support cylinder of the present invention. Fig. 6 is a schematic view showing the direction of the powder W of the three-dimensional applicator of the present invention. A three-dimensional applicator of the present invention comprises: a pressure grinding cover 1, a pressure grinding support cylinder 2, and a support cup 3. The pressure grinding cover 1 includes at least one annular side wall, and a partitioning platform 11 is disposed in the annular side wall. The first surface of the partitioning platform 11 forms a first grinding surface 12. The pressure grinding support cylinder 2 includes at least a support platform, a cylindrical boss 21 protruding from the support platform toward the first side, and an annular outer wall 24 surrounding the cylindrical boss 21; the end surface of the cylindrical boss 21 forms a second grinding surface 22 The second press surface 22 is combined with the annular outer wall 24 to form a crushing space 28.

In the present invention, it is a segmented grinding structure in which the first pair of pressing surfaces and the second pair of pressing surfaces are not in one plane, so that the powder W passes through the first direction at different inclination angles (relative to the direction of gravity). The speed of the pressing surface or the second pair of pressing surfaces is different. After the powder W is ground on the first pair of pressing surfaces, the powder W is guided into the second pair of pressing surfaces, and the powder W can be effectively controlled. The length of time that the second pair of press surfaces stays is small, which helps to perform finer grinding. In this process, since the powder W which is ground by the first pair of pressing surfaces is continuously guided away from the first pair of pressing surfaces, the powder W after the grinding can be prevented from accumulating on the first pair of pressing surfaces to prevent the pills. Y is hard and difficult to smash and other characteristics and is stuck.

The first pressing surface 12 in this embodiment is recessed from the periphery toward the center to form a conical recess, and the second pressing surface 22 is formed to protrude from the periphery toward the center to form a conical structure, and the cone of the conical recess of the first pressing surface 12 The angle is equal to the cone angle of the conical structure of the second grinding surface 22, and the first pair of pressing surfaces is a conical surface, but is not limited thereto. The conical surface structure of the first pair of pressing surfaces helps to grind the tablet Y, and the powder W is affected by gravity, and slides along the conical surface of the first pair of pressing surfaces toward the second pair of pressing surfaces. The surface of the inner wall of the annular side wall of the press-polished cover 1 is provided with a third grinding tooth 17, and the surface of the side wall of the cylindrical boss 21 of the support cylinder 2 is fourth grinding tooth 29, the third grinding tooth and the fourth grinding The teeth are alternately matched, and the second pair of pressing surfaces are round tube type pressing surfaces, but not limited thereto. In the present embodiment, the third grinding teeth 17 and the fourth grinding teeth 29 are both very fine for finely grinding the powder W. In one modification, the first grinding surface 12 is recessed from the periphery toward the center to form a hemispherical dimple, and the second pressing surface 22 is formed to protrude from the periphery toward the center to form a hemispherical projection, and the first pair of pressing surfaces is a hemispherical surface.

In a preferred embodiment, the second press surface 22 may include a plurality of powder leakage holes for rapidly grinding the powder W, but not limited thereto.

In a preferred embodiment, as the second frosting surface 22 is from the center to the periphery, the distribution density of the powder leakage holes is gradually increased, so that the powder W is subjected to grinding as many times as possible, and then falls from the first pair of pressing surfaces. The particle diameter of the small powder W.

In a preferred embodiment, the first dressing surface 12 is provided with a plurality of protruding first grinding teeth 13, and the second grinding surface 22 is provided with a plurality of protruding second grinding teeth 23, the first grinding teeth 13 When the second grinding tooth 23 is used for grinding, the distance between the first pressing surface 12 and the second pressing surface 22 changes to form a rhythmic amplitude in the height direction. When the first grinding surface 12 and the second grinding surface 22 are engaged with each other, a minimum spacing is formed therebetween, and when the first pressing surface 12 and the second pressing surface 22 are oppositely supported, a maximum spacing is formed therebetween, and The rhythm amplitude is the difference between the maximum spacing and the minimum spacing.

In another embodiment, the first grinding tooth 13 includes a plurality of radially linear first protrusions centered on the central axis of the press-fit cover 1, and the second grinding teeth 23 include a central axis of the cylindrical boss 21 A plurality of radially extending second protrusions of the center of the circle, the size and the gap of the first protrusion are equal to the size and the gap of the second protrusion, but are not limited thereto. In another embodiment, the first grinding tooth 13 includes a plurality of radial curved third protrusions centered on the central axis of the press-fit cover 1, and the second grinding teeth 23 include a central axis of the cylindrical boss 21 The fourth protrusion of the center of the plurality of radial curves, the size and the gap of the third protrusion are equal to the size and the gap of the fourth protrusion, but are not limited thereto.

The present invention also provides a method of using a stereo drug applicator for grinding a tablet Y, based on the above-described stereo drug applicator, the method of use comprising: a vertical rapid grinding state or a tilting fine grinding state. The vertical rapid grinding state includes: placing the tablet Y, and after inserting the pressure grinding cover 1 into the pressure grinding support cylinder 2, keeping the central axis of the pressure grinding support cylinder 2 in the direction of gravity, and spinning the pressure grinding cover 1 toward the pressure grinding support cylinder 2, The powder Y after the tablet Y is ground is ground by the first pair of pressing surfaces and guided to the second pair of pressing surfaces to continue grinding; the oblique fine grinding state includes: placing the tablet Y, and inserting the pressing cover 1 into the pressing support tube 2 Thereafter, the center axis of the press-braking support cylinder 2 is inclined to the direction of gravity, and the press-grinding cover 1 is spun to the press-braking support cylinder 2, and the powder W after the grinding of the tablet Y is ground by the first pair of pressing surfaces and then guided to The second pair of grinding surfaces continue to grind and gradually fall under the action of gravity; in the oblique fine grinding state, the powder Y after the grinding of the tablet Y passes through the second pair of pressing surfaces for more time than the vertical rapid grinding state, and the powder W passes through the second pair of pressures. Time to grind. In the inclined fine grinding state, the larger the inclination angle of the center axis of the press-supporting support cylinder 2 with the gravity direction, the smaller the particle diameter of the powder W. Alternatively, the smaller the gap between the annular side wall of the press-fit cover and the cylindrical boss of the press-fitting support cylinder, the smaller the particle diameter of the powder W. Alternatively, the longer the powder W passes through the second pair of pressing surfaces, the smaller the particle diameter of the powder W. The closer to the level, the slower the speed at which the powder W falls, the longer the powder W is ground between the second pair of pressing surfaces, the finer powder W is finer, and the gap between the second pair of pressing surfaces is also large. The fineness of the powder W is determined, and the powder W particles must be less than or equal to the gap to pass and fall. However, at the same time, when the pitch is large and the inclination angle, the powder W is slowly passed through the second pair of pressing surfaces, and the gap between the second pair of pressing surfaces is small, the best grinding effect can be obtained.

7 to 11 are schematic views showing the flow of use of the three-dimensional pressure applicator of the present invention. (Fig. 7 and Fig. 8 are schematic views showing the disassembly and assembly of the three-dimensional applicator of the present invention.) As shown in Figs. 7 to 11, the use of the spinning state of the present invention is as follows: first, the inverted stereo drug press And the press cover 1 and the press support cylinder 2 are unscrewed, and the tablet Y is placed in the first press face 12 of the press cover 1. Then, the press-reduction support cylinder 2 is screwed into the press-grinding cover 1, and the first grinding surface 12 of the press-grinding cover 1 and the second grinding surface 22 of the press-grinding support cylinder 2 are pressed against the tablet Y, and the inverted stereo-type pressing is performed. (ie the normal direction of recovery). Starting to press the pressure grinding cover 1 into the pressure grinding support cylinder 2, after the first pair of pressing surfaces (the combination of the first pressing surface 12 and the second pressing surface 22) grind the powder W, guide the powder W into a second pair of press faces (combination of the inner wall of the annular side wall of the press cover 1 with the side wall of the cylindrical boss 21 of the press support cylinder 2), and can effectively control the powder W to stay on the second pair of press faces The length of time helps to make finer grinding.

Figure 12 is a schematic view showing a state of oblique fine grinding of the three-dimensional applicator of the present invention. Figure 13 is a schematic view showing another oblique fine grinding state of the three-dimensional applicator of the present invention. As shown in FIGS. 12 and 13, the oblique fine grinding state of the present invention during the grinding process includes: placing the tablet Y, and after inserting the press cover 1 into the press-bracket support cylinder 2, tilting the center axis of the press-bracket support cylinder 2 to In the direction of gravity, the press-grinding cover 1 is spun to the press-supporting cylinder 2, and the powder W after the tablet Y is ground is ground by the first pair of pressing surfaces and guided to the second pair of pressing surfaces to continue grinding. At this time, the time during which the powder Y after the tablet Y is ground passes through the second pair of pressing surfaces is greater than the time during which the powder W passes through the second pair of pressing surfaces in the vertical rapid grinding state. In the inclined fine grinding state, the larger the inclination angle of the center axis of the press-supporting support cylinder 2 with the gravity direction, the smaller the particle diameter of the powder W. In Fig. 12, the angle O between the axis of the three-dimensional applicator and the direction of gravity P is C. The angle O between the axis O of the three-dimensional applicator in Fig. 13 and the direction of gravity P is D. Since the angle D is greater than the angle C, compare Figure 12 And 13, the first pair of pressing faces of the stereo drug press of Fig. 12 are closer to the horizontal level, so that the tablet Y is relatively slow to slide along the side of the first pair of pressing faces to the second pair after being ground. In the pressing surface; in Fig. 13, the first pair of pressing surfaces of the three-dimensional applicator are closer to the vertical direction so that the tablet Y is quickly ground and then slides along one side of the first pair of pressing surfaces. In the second pair of press faces, the more inclined (Fig. 13) three-dimensional applicator more easily and quickly guides the ground tablets Y into the second pair of press faces to prevent accumulation of the powder W. In Fig. 12, the first pair of pressing faces of the stereo drug press are closer to the vertical gravity direction, and the powder W after the tablet Y is ground quickly passes through the second pair of pressing faces, at which time the powder W is pressed by the second pair of pressing faces. The chance of grinding is less; while the first pair of pressing faces of the stereoplaster in Fig. 13 is at an angle with respect to the vertical direction of gravity, at which time the powder W will slowly pass through the second pair of pressing faces, during which the powder is The chance and time for the W to be ground by the second pair of press faces is greatly increased, and the powder W having a smaller particle size after being ground for a plurality of times by the second pair of press faces falls into the cup 3 through the powder leakage holes 26. Subsequently, the powder W in the cup 3 can be taken by unscrewing the cup 3 and pressing the support cylinder 2.

The press-grinding cover 1 includes a first annular side wall 16 and a second annular side wall 14, the first grinding surface 12 is formed in the second annular side wall 14, and the second annular side wall 14 is wrapped around the first annular side After the wall 16, the inner wall of the second annular side wall 14 is provided with a first loose fit wide pitch thread 15; the outer wall of the annular outer wall 24 of the press support sleeve 2 is provided with a second loose fit wide pitch thread 25, and the grinding cover 1 The first annular side wall 16 is inserted between the annular outer wall 24 of the press-retaining support cylinder 2 and the cylindrical boss 21, and the inner wall of the second annular side wall 14 is screwed to the outer wall of the annular outer wall 24. The thread slot width E of the first loose fit wide pitch thread 15 and the second loose fit wide pitch thread 25 are both greater than or equal to the sum of the thread width F and the rhythmic amplitude. The first pressing surface 12 is recessed from the periphery toward the center to form a conical recess, and the second pressing surface 22 is formed to protrude from the periphery toward the center to form a conical structure, and the conical angle of the conical pit of the first grinding surface 12 and the second pressure The conical angle of the conical surface of the grinding surface 22 is equal, and the first pair of pressing surfaces are conical surfaces. In the embodiment, the first pressing surface 12 of the three-dimensional applicator is provided with a plurality of protruding first grinding teeth 13, and the second pressing surface 22 is provided with a plurality of protruding second grinding teeth 23. The annular side wall of the pressure grinding cover 1 is provided with a first loose-fit wide-width thread 15 for pressing the annular outer wall 24 of the support cylinder 2 A second loose fit wide pitch thread 25 is provided, and the first loose fit wide pitch thread 15 is threadedly engaged with the second loose fit wide pitch thread 25. In the present invention, it is a segmented grinding structure in which the first pair of pressing surfaces and the second pair of pressing surfaces are not in one plane, so that the powder W passes through the first direction at different inclination angles (relative to the direction of gravity). The speed of the pressing surface or the second pair of pressing surfaces is different. After the powder W is ground on the first pair of pressing surfaces, the powder W is guided into the second pair of pressing surfaces, and the powder W can be effectively controlled. The length of time that the second pair of press surfaces stays is small, which helps to perform finer grinding. In this process, since the powder W which is ground by the first pair of pressing surfaces is continuously guided away from the first pair of pressing surfaces, the powder W after the grinding can be prevented from accumulating on the first pair of pressing surfaces to prevent the pills. Y is hard and difficult to smash and other characteristics and is stuck.

Moreover, the applicator of the present invention can be used not only for pressing the tablets, but also for pressing the fruits, seasonings, confectionery, etc., which need to be ground or food, which can also save time and effort, and is easy to clean. No pollution effect.

Regarding the specific action and characteristics of the first grinding surface 12 and the second grinding surface 22 in the press grinding process in the present invention, the crushing is performed in the early and middle stages of the press grinding (step S100) and the late pressing (step S200). Introduced as follows:

Step S100, crushing to the early and middle stage of the pressing (there are more tablets Y crushing the tablet Y particles between the pressing surfaces, and the pressing surface grinding teeth are indirectly staggered), and the step S100 includes the following steps:

Step S101, when the cap is started, since there is no resistance on the pressing surface, under the action of gravity, the lower surface of the grinding cap and the upper surface of the pressing support cylinder are in contact with each other and follow the spiral path, and the thread has no force. behavior.

Step S102, when the pressing surface of the pressure grinding cover contacts the tablet Y, the resistance of the tablet Y rises up until the upper surface of the threaded cover thread is in contact with the lower surface of the threaded support cylinder thread, and the threading starts to force to break. .

Step S103, when the tablet Y is fragile or the tablet Y is small, the resistance is small, the thread force directly breaks the tablet Y, and there is no jamming, and the broken tablet Y large particle acts on the edged pressing surface. The lower thread is broken up and continues to be ground, and the wide-distance thread does not work until the later stage of the pressing (there are fewer tablets Y broken particles between the pressing surfaces, and the grinding surface is directly staggered).

Step S104, when the tablet Y is hard or the tablet Y is more, the resistance is large, and after the thread is applied, the pressing surface is descended, and the tablet Y is stuck in the edge of the upper and lower pressing surface to form a stuck condition, and at this time, a certain angle needs to be rotated ( It can be 0°-360°). On the one hand, the upper surface of the pressure-receiving cover thread and the lower surface of the pressure-receiving support cylinder are separated to produce a free-running gap, which provides a wide-distance thread action stroke. On the other hand, during the swirling process, the pressure grinding The surface pressure grinding tooth changes the position of the tablet Y, which is beneficial to the next thread breaking force. At this time, several reciprocating rotations can be performed, and the wide-distance thread exerts the first action stage, and the pressing surface is applied under the pressure of applying a certain hand. The grinding tooth starts to rotate in place until the hard tablet Y is broken or the tablet Y is gradually decreased, and the above-described step S103 is entered.

In the steps S101 to S104, the wide-width thread groove width can be grounded as long as the tooth width is larger than the tooth width, and the larger the groove width (pitch), the larger the in-situ rotation angle.

In step S200, in the later stage of press grinding (there are fewer tablets Y crushing particles between the pressing surfaces, and the pressing surface grinding teeth are directly staggered) to the cleaning period state, step S200 includes the following steps:

In step S201, the post-grinding medicine will be less and less, and the pressing grinding teeth will start to be in direct contact. If the screwing is continued, (the upper surface of the grinding cap and the lower surface of the pressing support cylinder thread are in contact with each other), then it will appear at a certain angle. The grinding teeth are stuck. In extreme cases (cleaning phase), the thread will lock up. Therefore, it is not necessary to screw in at the end of the grinding process. It only needs to be directly interlaced (with a clear sound) at the beginning of the grinding tooth to perform the rounding, and enter the wide thread to play the second stage. .

Step S202, the wide-distance thread exerts the second action phase and the wide-distance thread in step S104 is different in the first action phase. In this case, the broken tablet Y particles can be easily removed without applying the pressing force of the hand. Grind into powder and fall into the receiving bin.

In step S203 and the cleaning stage, referring to the above step S201, after the sounding of the grinding teeth is heard, the ground rotation is performed, and the grinding surface is interlaced with the grinding surface, and the regular ups and downs are performed to achieve the effect of flushing the residual powder W by the airflow. .

Step S204, the amplitude and frequency of the rhythm depending on the cleaning effect, and the method for increasing the amplitude of the rhythm is that the grinding teeth are more deeply staggered, and the width of the wide thread groove is at least larger than the tooth width + the height of the grinding tooth, so that a large rhythmic amplitude can be realized. In the case where the tooth width is constant, the larger the groove width (pitch), the larger the achievable rhythm. The deeper the interdental degree of the grinding teeth, the better the effect of the grinding and scattering of the tablet Y broken particles in the second action stage.

In the steps S201 to S204, the rhythmic frequency is positively correlated with the number of grinding teeth, but the number of grinding teeth is less constrained by the wide pitch thread.

Therefore, the cooperation of the first loose-fit wide-width thread 15 and the second loose-fit wide-distance thread 25 in the present invention can achieve the labor-saving effect by the screw drive, and can realize the reciprocating grinding effect of the grinding surface being separated from the thread drive without separation. .

The threaded peaks and thread valleys of the loose fit drive thread can achieve a helical fit, but are different from conventional threads. There is a free gap between the two threads, which is much larger than the normal thread matching clearance (generally a working range of about 0.3 mm). In actual practice, the gap is about 2-3 mm, and the actual distance may be 2-3 cm. In the present invention, the thread groove width E of the first loose fit wide pitch thread 15 and the second loose fit wide pitch thread 25 are both greater than or equal to the sum of the thread width F and the rhythmic amplitude, and the pressure is made by the fit gap The cover has a section that is free to move up and down relative to the support cylinder and is free to "in situ", ie, it is rotated but not subject to the thread and must be moved in or out. The loosely matched drive thread can realize the forward rotation linear drive advancement of the conventional threaded engagement, assist the crushing of the tablet Y, and the reverse rotation linear drive back to separate the pressure grinding cover and the support cylinder. The thread drive advances, which can assist the crushing of the tablet Y into a large piece until it is difficult to recompress; the slight reverse rotation causes the pressure grinding cover to enter the range of “free wide-distance thread gap”, and the pressure-grinding cover can be controlled and operated at the hand. Next, the continuous reciprocating rotary grinding operation in which the second pressing surface 22 is not separated is performed on the press-reduction support cylinder 2, and the pressing surface is reciprocated close/away as the standard thread of the prior art rotates. Effective grinding is not possible.

Since the non-standard thread loose fit wide-width thread is used in the present invention to screw the press cover 1 and the press support support 2, the loose fit wide pitch thread in the present invention means that the thread groove width of the thread is significantly larger than the thread. The width of the teeth allows the thread width to move up and down within the width of the thread groove. In the present invention, the height of the first grinding tooth protruding from the first pressing surface ranges from 0.1 mm to 10 mm; the height of the second grinding tooth protruding from the second pressing surface is 0.1 Mm to 10 mm; the range of the thread width of the first loose fit wide pitch thread and the second loose fit wide pitch thread is 0.1 Up to 10 mm; the thread groove width of the first loose fit wide pitch thread and the second loose fit wide pitch thread is in the range of 0.2 to 20 mm.

Figure 20 is a schematic view of the threaded engagement of the spinning state of the present invention. As shown in FIG. 20, and in addition, the press-fit cover 1 of the present invention can be engaged by the first loose-fit wide-width thread 15 and the second loose-fit wide-width thread 25 in the spinning state, the first loose fit width The thread 15 is in close contact with the second loose-fit wide-distance thread 25, and the pressure-grinding cover 1 can perform the spinning reduction in the axial direction, and the first pressing surface 12 of the driving-polished cover 1 is pressed against the second of the pressure-retaining support cylinder 2 Tablet Y of the press surface 22 . The spinning state is very helpful for breaking the tablet Y at the beginning.

Figure 21 is a schematic view of the threaded engagement in the ground state of the present invention. As shown in Fig. 21, but when the stacking of the powder W is not carried out, when it is impossible or difficult to continue the spinning down, the counter-rotating is to press the cap into the "free zone". At this time, due to the thread groove width in the present invention Sufficiently wide, the thread width can be moved up and down within the range of the thread groove width, even if the first loose fit wide thread 15 and the second loose fit wide thread 25 are suspended, even the first loose fit width The rotation of the thread 15 is performed at a certain angle, and the height between the pressure grinding cover 1 and the pressure grinding support cylinder 2 does not change any more, which is equivalent to the height of the pressure grinding support cylinder 2 relative to the pressure grinding support cylinder 2. In-situ fit rotary grinding. Therefore, the user can use the first grinding surface 12 of the pressure grinding cover 1 by positively rotating a certain angle - a certain angle of the reverse rotation - a certain angle of the positive rotation - a certain angle of the reverse rotation ... forming a reciprocating positive and negative alternate rotation. The tablet Y of the second dressing surface 22 of the press support cylinder 2 is ground. The grinding state is very advantageous for solving the problem of jamming when the powder W is piled up.

Moreover, the spinning state and the grinding state in the present invention can be flexibly used as long as the tablet Y can be ground by the spinning state and used in the spinning state (the first loose-fit wide-width thread 15 is closely attached to the second loose-fit width). Thread 25, for spinning down). However, once the accumulation resistance of the powder W is increased, the reverse rotation retracting thread can enter the "free up and down" interval due to the resistance of the bite, and the first pressing surface 12 is always maintained relative to the second pressing surface. In the case of the pressure of 22, the press-grinding cover 1 can realize the in-situ rotary grinding with respect to the height of the press-supporting support cylinder 2, rapidly destroying the stacked shape of the powder W, and after continuing to grind the powder W, the first loose fit wide-distance thread After 15, it can be lowered against the second loose-fit wide-width thread 25, and the spin-down is again performed (returning to the spinning state). In the prior art, rotary applicators use standard threads. The thread groove width in prior art rotary applicators is almost equal to the thread width. When the tablet Y is stuck, it cannot continue to rotate downward. After the powder W is pressed in, it is almost integrated and cannot be pressed down, so it can only be reversed and the partial thread can be withdrawn. The prior art cannot achieve the effect of the flexible replacement of the spinning state and the grinding state in the present invention.

Further, the first lapping tooth 13 and the second lapping tooth 23 of the present invention are alternately alternated between staggered engagement and abutment to form a rhythmic fit. The interlaced engagement in the present invention means that each of the first grinding teeth 13 at least partially enters the gap of the adjacent two second grinding teeth 23, and likewise, each of the second grinding teeth 23 at least partially enters the phase. In the gap between the two adjacent first grinding teeth 13. This minimizes the spacing between the first press surface 12 and the second sand surface 22. The abutment in the present invention means that the tip of each of the first grinding teeth 13 is in supporting contact with the tip of the corresponding second grinding tooth 23, and the first grinding tooth 13 does not enter the gap of the second grinding tooth 23. Similarly, the second grinding teeth 23 do not enter the gap of the first grinding teeth 13. This maximizes the spacing between the first press surface 12 and the second sand surface 22. The effect of the rhythmic grinding of the first grinding tooth 13 and the second grinding tooth 23 can more quickly destroy the shape of the powder W stack, The problem of stuck when the drug powder W is piled up.

In the present embodiment, the rhythmic effect of the first grinding tooth 13 and the second grinding tooth 23 or other special grinding surface can not achieve the "adhesive" grinding action of the two surfaces if the ordinary thread of the prior art drug press is used. Because the standard pitch of ordinary threads is not allowed. However, if the wide-distance thread is used, the optimal rhythmic tooth height, the shape and the free stroke of the wide-distance thread can be combined to effectively realize the grinding action and assist in the rapid production of finer powder.

In a preferred embodiment, the outer periphery of the press-retaining support cylinder 2 is further provided with an outer shoulder 27, and the second annular side wall 14 abuts the outer shoulder 27. A rhythmic force is formed as the first grinding tooth 13 and the second grinding tooth 23 are alternately alternated between the staggered engagement and the abutment. The second annular side wall 14 can repeatedly crimp the outer shoulder 27 (corresponding to the sealed state) or leave the outer shoulder 27 with a certain gap (which can be supplied with air). This repeated alternating inhalation state can be rhythmically The air is guided into the pressing space 28 for blowing off the powder W adhering to the surface of the first pressing surface and the surface of the second pressing surface, and has a function of self-cleaning. The number and height of the grinding teeth are positively related to the frequency of the “rhythm” or the effect of generating airflow, which is convenient for adjusting the self-cleaning effect.

In this embodiment, the first pair of pressing surfaces, the second pair of pressing surfaces, the segmented grinding structure, the loose fit wide thread screwing structure and the grinding toothed dynamic matching are combined to obtain the fastest grinding. The effect helps to quickly grind the powder W and saves effort.

Figure 22 is a cross-sectional view showing another three-dimensional applicator of the present invention. As shown in Fig. 22, in a variant, the holder cup 3 of the press-grinding cover 1 and the second side of the press-receiving support cylinder 2 are combined to form a storage compartment 3 in which the cartridge 32 can be placed.

Figure 23 is a cross-sectional view showing another three-dimensional applicator of the present invention. As shown in FIG. 23, in another variation, the press-grinding cover 1 includes a first annular side wall 16, and the outer wall of the first annular side wall 16 is provided with a first loose-fit wide-width thread 15; The inner wall of the annular outer wall 24 is provided with a second loose fit wide pitch thread 25, the outer wall of the first annular side wall 16 being threaded into the inner wall of the annular outer wall 24. In this embodiment, the pressure grinding cover 1 only needs to be provided with an annular side wall, which saves cost, but compared to the two annular side walls (ie, the second annular side wall 14, the first annular side wall 16), the powder W will Relatively easy to spread out.

(2) When the three-dimensional pressure applicator of the present invention is stuck in a state in which the tablet is hard and difficult to be pulverized, the first polishing surface and the second polishing surface are caused to cooperate to form a grinding effect powder. Loosen, rearrange the heap The opportunity to stack is effective to prevent jamming.
