Abstract

PROBLEM TO BE SOLVED: To provide a safe tablet divider which prevents a cutter from being exposed from a lid body when the lid body of the tablet divider is open.SOLUTION: When a lid body 20 is open, an energizing force of a spring 71 is not applied to an arm 41 constituting a cutter lifting mechanism M. At this time, the spring 71 pushes up a flange part 53 formed in a support base 51, and a cutter 61 fitted to the support base 51 rises simultaneously. In this state, the cutter 61 is configured not to protrude from a cutter passage hole 32 formed on a protection plate 30, thereby preventing hands and fingers of a user from being cut. Thus, a tablet divider 1 can be made very safe.SELECTED DRAWING: Figure 6

Description

  The present invention relates to a tablet dividing device used when a tablet, which is a solid pharmaceutical product, is used by dividing a tablet into half according to the dose.

A conventional tablet dividing device is shown in FIG.
The tablet dividing device 100 is generally configured by connecting a base 110 and a lid 120 so as to be freely opened and closed by a hinge part 140.

  The base 110 has a pair of positioning plates 111 erected in a substantially C shape in plan view. The positioning plate 111 has a gap 111a located on the cut line at the apex thereof. Further, a space between the pair of positioning plates 111 forms a tablet placement portion 112 on which the tablet D is placed.

  On the other hand, a support base 151 is integrally formed on the back surface 122 of the lid body 121 of the lid body 120 that is connected to the hinge portion 140 so as to be freely opened and closed. Further, a groove 151 a is recessed in the support base 151. A cutter 161 for cutting the tablet D is press-fitted and attached to the groove 151a.

  As described above, the conventional tablet dividing device 100 configured as described above places the tablet D on the tablet placement portion 112 of the base 110 so as to press the tablet D against the positioning plate 111. The placed tablet D is set so that the cut line is positioned to pass through the center of the tablet D.

  Then, after placing the tablet D, if the lid 120 is closed while being manually pressed so as to cover the base 110, the cutter 161 passes between the gaps 111a located at the center of the tablet D, and the tablet D is disconnected. In this way, the tablet D is divided into two substantially evenly to obtain a half tablet d.

  In addition, the disclosed example of Japanese Patent Publication No. 6-41546 (Applicant: Saneigen FFI Co., Ltd.), which is the disclosed Patent Document 1, has substantially the same configuration as the conventional example described above. A commercially available tablet dividing device also has a configuration and a structure that are substantially the same as those of the above-described embodiments and Patent Document 1.

  However, the above-described conventional tablet dividing device 100 including Patent Document 1 has a gripping force and a visual acuity because the cutter 161 for cutting the tablet D is exposed as shown in FIG. 8 when the lid 120 is in the open state. When it is used by elderly people who are declining, there is a drawback in that their hands and fingers are cut and injured.

  Japanese Utility Model Publication No. 6-41546

  In view of the above-described conventional drawbacks, the present invention is used by elderly people and children whose gripping power and visual acuity are reduced without exposing the cutter even when the lid of the tablet dividing device is open. At the time, an object is to provide a safe tablet dividing device that does not accidentally cut a hand or a finger with a cutter.

In order to achieve the above object, the present invention described in claim 1

Further, the bearing plate 24 is provided with a bearing portion 24a.

  Similarly, a pair of guide portions 25 are formed on the back surface 22a. The space of the guide part 25 which opposes becomes the guide groove part 25a. Further, a hinge piece 26 constituting the other side of the hinge portion 14 is integrally formed on the peripheral wall surface 21 a of the lid body 21. The hinge piece 26 has a shaft hole 26a. The shaft 15a of the hinge piece 15 formed on the base 10 is fitted into the shaft hole 26a, so that the base 10 and the lid 20 can be opened and closed.

  In the lid 20, a guide pin 23, a bearing plate 24, a guide part 25, and a hinge piece 26 provided on the back surface 22 a of the ceiling part 22 of the lid body 21 are integrally formed by resin injection molding. Therefore, since the number of parts is only one, productivity is good and assembly is facilitated, resulting in cost reduction and quality improvement.

  Next, the protection plate 30 is provided with a cutter passage hole 32 through which the cutter 61 as the cutting portion 60 passes together with the pin passage hole 31. In this cutter passage hole 32, a convex portion 32a shown in FIG.

  The convex portion 32 functions to prevent the cutter 61 from shaking and prevent the cutter 61 from being broken, and the finger enters the cutter passage hole 32 when the finger is pressed against the cutter passage hole 32 during use. In addition, it also has a function of preventing the cutter 61 from cutting a finger.

  Further, the protection plate 30 is provided with a stepped hole 33 for the guide pin 23 of the lid 20 to be press-fitted and attached. The stepped hole 33 has a stepped shape including a large-diameter portion 33a and a small-diameter portion 33b. A press-fit portion 23a of the guide pin 23 is press-fitted into the small diameter portion 33b.

  Further, the protection plate 30 is provided with a closing plate 34 that closes the bearing plate 24 at the same position as the bearing plate 24 in plan view (see FIG. 5). The closing plate 34 abuts on the bearing plate 24 when the protection plate 30 is fixed to the lid 20 by a fixing means such as caulking. Then, by abutting, it functions as a shaft hole of a shaft 41a of an arm 41 described later. Furthermore, a positioning pin 35 for positioning the protective plate 30 with respect to the lid 20 is erected on the protective plate 30 by being fitted to the outside of the guide portion 25 of the lid 20. .

  Next, the pressing part 40 is composed of a pair of arms 41. The arm 41 is arranged point-symmetrically below the lid body 21 in a plan view (see FIG. 5). A shaft 41 a is projected from the central portion of the arm 41. Further, a pressing portion 41 b and the other pressing portion 41 c are provided below the both ends of the arm 41. The shaft 41 a is disposed on the bearing portion 24 a of the bearing plate 24.

  The arm 41 includes a bearing plate 24 formed on the lid body 21 and a closing plate 34 formed on the back side of the protection plate 30, and a shaft 41 a is pivotally supported in the formed shaft hole. Further, the arm 41 is disposed with a predetermined angle (about 56 ° in plan view in the present embodiment) with respect to the cutter 61 which is the cutting portion 60 attached to the support base 51. .

  In addition, in the case of the present embodiment, the arm 41 is provided with a predetermined angle. When the cutter lifting mechanism M is configured inside the lid body 21 having an outer diameter of about 50 mm, the pressing portion 40 is pressed. In order to increase the pressure, the pressing force can be increased by increasing the length of the arm 41 as much as possible.

  However, in order to make the tablet dividing device 1 as compact as possible, the arm 41 is arranged at a predetermined angle so that the length of the arm 41 is longer than that at a right angle with respect to the cutter 61. Therefore, the pressing force can be increased.

  Next, in the support portion 50, the support base 51, the guide end 52 that guides the lifting operation of the support base 51, and the flange portion 53 in which the insertion hole 53a through which the guide pin 23 is inserted are viewed in plan view (see FIG. 5)). A spring 71, which is a compression spring, which is an elastic portion 70, is attached to the boss portion 54 so that it does not come off during operation.

  Further, a groove 55 for mounting a cutter 61 as a cutting portion 60 is provided below the support base 51 so as to be opposed to the groove. The longitudinal dimension of the groove 55 is slightly smaller than the width dimension of the cutter 61. Therefore, when the cutter 61 is press-fitted and attached, the cutter 61 does not easily come off from the support base 51.

  Next, the cutter lifting mechanism M attached in the lid 20 will be described in detail with reference to FIG. For portions that cannot be illustrated in FIG. 4, refer to any of FIGS. 1 to 3 and FIG. 5.

  First, the shaft 41a protruding from the arm 41 is installed in the bearing portion 24a recessed in the bearing plate 24 with the ceiling portion 22 of the lid main body 21 facing down. In this state, the arm 41 can rotate about the shaft 41a.

  Next, it attaches so that the guide end 52 of the support stand 51 in the state to which the cutter 61 was attached may be fitted in the guide groove part 25a of the guide part 25 formed in the lid body 21. At substantially the same time, the guide pin 23 is inserted into the insertion hole 53a formed in the flange 53 of the support base 51. In this state, the spring 71 is connected to the guide pin 23 so as to be fitted to the boss portion 54 of the flange portion 53.

  After each of the above-described members constituting the cutter lifting mechanism M is installed in the lid main body 21, the protection plate 30 is fixed by a fixing means such as caulking so as to be fitted into the lid main body 21. At this time, the guide pin 23 is inserted into the large-diameter portion 33a of the protection plate 30, and the press-fit portion 23a of the guide pin 23 is press-fitted into the small-diameter portion 33b to fix the guide pin 23. In this way, the cutter lifting mechanism M becomes operable.

  The operation of the tablet dividing device 1 configured as described above will be described in detail with reference to FIGS. 6 and 7. 6 and 7 will be referred to any one of FIGS. 1 to 5.

  As shown in FIG. 6, the cutter lifting mechanism M before cutting the tablet D (see FIG. 1) in the opened state (the state shown in FIG. 1) is pushed up by the support base 51 by the biasing force of the spring 71. At the same time, the upper surface 51a of the support base 51 and the one pressing portion 41b of the arm 41 provided therewith are pushed up.

  Similarly, the support base 51 from which the collar portion 53 is pushed up by the biasing force of the spring 71 is also pushed up by the attached cutter 61 and is raised. In this state, the cutter 61 is structured so as not to be exposed from the cutter passage hole 32 formed in the protective plate 30, so that the user does not cut his hand or finger. Therefore, it is clear that the tablet dividing device 1 of the present invention is a very safe tablet dividing device.

  Next, as shown in FIG. 7, the tablet D (see FIG. 1) is cut in the closing operation state (operation state until the lid body 20 is rotated by the hinge portion 14 to cover the base 10). In the cutter lifting mechanism M in the state of being pressed, the other pressing portion 41c of the arm 41 which is the pressing portion 40 is pressed against the lifting surface 13a of the lifting pin 13 erected on the base 10, Since the arm 41 is lifted and raised, the arm 41 rotates around the shaft 41a, and the one pressing portion 41b is lowered by pressing.

  Next, when the push-up force by the push-up surface 13a becomes larger than the urging force of the compression spring 71, the one pressing portion 41b in a state of being in contact with the upper surface 51a of the support base 51 presses the support base 51 and descends. Go. Then, in a state where the lowering is at the bottom dead center, the cutter 61 passes through the cutter passage hole 32 formed in the protection plate 30 and cuts the tablet D (see FIG. 1) in half. In this way, the divided tablet D becomes a half tablet d (see FIG. 1).
