  However, when the stool collection tube is transported, if the conventional packaging form such as a transport bag with a dedicated chuck is used, the direction of the stool collection tube in the transport bag is not constant. For this reason, in order to take out the stool collection tube from the transport bag, there is no other way than to rely on humans, and it is difficult to automate the stool collection tube removal process.

  The present invention has been made based on the circumstances as described above, and the stored article can be easily taken out. Especially when the stool sample is configured for transportation of a stool collection tube, It is an object of the present invention to provide a blister pack that can easily automate the process of taking out a stool collection tube at the time of inspection.

The blister pack of the present invention is a blister pack comprising a molded product of a resin sheet, and an article storage space is formed inside by fitting one case and the other case to the other case through a bent portion. A pack,
At least one of the one case and the other case continues to the bent portion via a curved portion that protrudes inward when the one case and the other case are fitted. It is characterized by that.

  The blister pack of the present invention is suitably used for transporting a stool collection tube holding a stool sample therein.

In the blister pack of the present invention, the one case and the other case have a flange portion at a position on the opening / closing end side at least on the outer periphery,
The flange portion in at least one case of the one case and the other case is configured to be inclined so as to expand outward in a state where the one case and the other case are fitted. Preferably it is.
In such a configuration, it is more preferable that a protrusion is formed on the inner surface of the flange portion of at least one case of the one case and the other case.

Furthermore, in the blister pack of the present invention, the stool collection tube is different in outer shape from one end and the other end in the tube axis direction,
The article storage space is preferably configured to have a space shape that matches the outer shape of at least one of the one end and the other end of the stool collection tube.

  Furthermore, in the blister pack of the present invention, a stool collection tube receiving recess for receiving and holding the stool collection tube is formed in the one case, and the stool collection tube receiving recess is provided with the stool collection tube receiving recess. In a state where the stool collection tube is held in the tube housing recess, it is preferable to have a bulging portion that forms a space between the wall surface of the stool collection tube housing recess and the outer peripheral surface of the stool collection tube. .

Furthermore, in the blister pack of the present invention, an engagement concave groove extending in the tube axis direction of the stool collection tube is formed on the inner surface of the stool collection tube storage recess in the one case,
The other case is formed with a frame-like convex part that fits the opening shape of the stool collection tube receiving concave part, and the engaging case is engaged with the engaging concave groove on the outer peripheral surface of the convex part.

FIG. 2 is a plan side perspective view showing a state in which the stool collection blister pack shown in FIG. 1 is in an open state. FIG. 3 is a plan side perspective view showing the stool collection blister pack shown in FIG. 1 in a developed state. FIG. 4 is a plan view showing the configuration of the main body in the stool collection blister pack shown in FIG. 1.
The blister pack 10 for a stool collection tube is made of a molded product obtained by, for example, vacuum forming or pressure forming of a resin sheet, and a body portion 11 that is one case and a lid portion 30 that is the other case are bent portions. It is configured to be integrally connected via 40. The blister pack 10 for a stool collection tube has a substantially rectangular shape in a plan view when the main body 11 and the lid 30 are fitted (closed state).

As the resin sheet, for example, a sheet made of a transparent thermoplastic resin such as a polyethylene terephthalate resin, a vinyl chloride resin, a polypropylene resin, or a polystyrene resin can be used. By using a transparent resin sheet, it can be visually recognized from the outside whether or not the stool collection tube 50 is housed inside. In particular, when the blister pack is for a stool collection tube, a color transparent resin sheet such as green or blue, which is complementary to the color of the stool sample held in the stool collection tube 50, is used. It is preferable. In general, since the stool collection tube 50 is translucent, the blister pack is colored and transparent, so that it can be seen as a color different from the original color of the stool sample, for example, black (mixed color). .
Moreover, it is preferable that the thickness of a resin sheet is 0.2-0.3 mm, for example.

The main body 11 includes a stool collection tube receiving recess 20 that receives and holds one stool collection tube 50, and a flange portion 15 that extends outward over the entire circumference of the opening edge of the stool collection tube storage recess 20. Have.
The stool collection tube 50 housed in the stool collection tube blister pack 10 of this example has different outer shapes at one end and the other end in the tube axis direction, with one end opening and the other end being, for example, A cylindrical stool collection tube main body 51 closed in a hemispherical shape and a cylindrical cap 52 detachably attached to an opening of the stool collection tube main body 51 are configured.

  The stool collection tube recess 20 includes a first recess 21 that forms a plate-like space, and a second recess 22 that is continuous to the bottom surface of the first recess 21 via a step 23.

  On the inner surface of the first recess 21, an engaging groove 24 extending in the tube axis direction of the stool collection tube 50 (hereinafter referred to as “length direction”) is formed. Specifically, the engaging groove 24 is formed in each of the inner surfaces of a pair of peripheral walls that define the first recess 21 and extend in the length direction so as to extend in the length direction, for example, parallel to the opening surface. It is formed to extend.

  The second recess 22 has a spatial shape that matches the outer shape of at least one of the one end and the other end of the stool collection tube 50. In this example, the second concave portion 22 has a space shape in which one end side portion in the length direction is adapted to the outer shape of the cap 52 of the stool collection tube 50 and the other end portion is a stool collection tube of the stool collection tube 50. It has a space shape that matches the outer shape of the main body 51. That is, in this blister pack 10 for a stool collection tube, the stool collection tube 50 is positioned on the bent portion side (hereinafter referred to as “connecting end side”) where the stool collection tube main body portion is the other end side of the second recess 22. In such a position, it is accommodated in the second recess 22. Therefore, as shown in FIG. 5, the inner surface of the end wall on the connecting end side and the inner surface of the bottom wall of the second recess 22 have a shape along the spherical surface of the other end portion of the stool collection tube main body 51. . Further, as shown in FIG. 6, the inner surface of the end wall and the inner surface of the bottom wall on one end side (hereinafter referred to as “opening / closing end side”) of the second recess 22 are the outer periphery of one end surface and one end portion of the cap 52, respectively. It has a shape along the surface.

  The second recess 22 bulges to form a space S between the wall surface of the second recess 22 and the outer peripheral surface of the stool collection tube 50 in a state where the stool collection tube 50 is held in the second recess 22. Part 26. Specifically, the bulging portions 26 are formed to face each other in the center portion in the length direction of each of the pair of peripheral walls that extend in the length direction so as to face each other and define the second recess 22. The space S formed by having the bulging portion 26 should be used as a space for inserting a stool collection tube removal jig when automating the stool collection tube 50 extraction process when a stool sample is inspected. Can do.

  In addition, a protrusion for holding the stool collection tube 50 in a fitted state is formed on each of the inner surfaces of the pair of peripheral walls that define the second recess 22 and extend in the length direction so as to face each other. In this example, a pair of fitting projections 25a are formed on the peripheral wall of the opening / closing end side portion of the second recess 22 so as to face each other, and the cap portion of the stool collection tube 50 is the pair of fitting projections. It is pinched by 25a and is held in a fitted state. Further, a pair of fitting projections 25b are formed on the peripheral wall of the rear end side portion of the second recess 22 so as to face each other, and the stool collection tube main body portion in the stool collection tube 50 is the pair of fitting projections. It is pinched by the portion 25b and held in a fitted state.

  A portion (hereinafter referred to as “opening / closing end side flange portion 16”) of the flange portion 15 of the main body portion 11 which will be described later will be described later in a state where the main body portion 11 and the lid portion 30 are fitted. The lid 30 is inclined so as to expand outward in the longitudinal direction with respect to the opening / closing end side flange portion 36 (see FIG. 6), and thereby the opening / closing end side flange portion 16 of the main body portion 11. A gap is formed between the inner surface and the inner surface of the open / close end side flange portion 36 in the lid portion 30. That is, in the blister pack 10 for the stool collection tube, the open / close end is always open in the state where the lid 30 is closed.

  The lid portion 30 of the stool collection tube blister pack 10 is formed so as to protrude to the inner surface side, and a projection 31 inserted into the first recess 21 in the stool collection tube receiving recess 20 of the main body 11, and the projection 31 has a flange portion 35 formed so as to extend outward over the entire circumference of the outer periphery at the end portion located on the outer surface side of 31.

  In this stool collection blister pack 10, for example, a label on which personal information such as the name of the subject is recorded is affixed to the outer surface of the lid 30, and therefore the outer surface of the lid 30 may be a flat surface. preferable. However, if the lid portion 30 is configured in a flat sheet shape, the lid portion 30 may be dropped due to deformation of the lid portion 30 during transportation, for example, so that the lid portion 30 has sufficient strength. It is desirable to have a configuration having For this reason, in this example, the convex portion 31 is configured in a rectangular frame shape that matches the opening shape of the stool collection tube accommodating concave portion 20 of the main body portion 11. When viewed from the outer surface side of the lid portion 30, the convex portion 31 is configured by a narrow groove having a narrow width.

  A space formed on the inner surface side of the lid portion 30 and surrounded by the convex portion 31 has a space shape that is at least partially compatible with the outer shape of the stool collection tube 50. That is, in this example, as shown in FIG. 5, the inner wall on the connection end side of the convex portion 31 has a curved shape along the spherical surface related to the other end portion of the stool collection tube main body 51. On the other hand, as shown in FIG. 6, the inner wall on the open / close end side of the convex portion 31 has a flat shape along one end surface of the cap 52 in the stool collection tube 50.

  Further, on each of the outer surfaces of the outer walls of the pair of peripheral wall portions that extend in the length direction so as to oppose each other in the convex portion 31, an engagement concave formed in the first concave portion 21 in the stool collection tube concave portion 20 of the main body portion 11. Engaging protrusions 32 that are engaged with the respective grooves 24 are formed. Thus, in this blister pack 10 for stool collection tubes, since the engaging groove extending in the length direction is formed by the engaging groove 24 in the main body 11 and the engaging protrusion 32 in the lid 30, the lid portion Although the structure can be easily opened, the lid 30 can be prevented from being opened unexpectedly during transportation of the stool collection blister pack 10 or the like.

  A protrusion 38 is formed on the inner surface of a portion (opening / closing end side flange portion 36) located on the opening / closing end side of the flange portion 35 of the lid portion 30. The protrusions for preventing adhesion may be formed on the inner surface of the open / close end side flange portion 16 of the main body 11. Further, the open / close end side flange portion 36 in the lid portion 30 may be inclined so as to expand outward in the longitudinal direction with respect to the open / close end side flange portion 16 in the main body portion 11.

  As shown in FIG. 7, the bent portion 40 in the stool collection blister pack 10 is formed in an arc shape so as to be convex toward the main body portion 11 side in the unfolded state.

  Thus, in the blister pack 10 for a stool collection tube described above, the connecting end side flange portion 17 in the main body portion 11 is inward (the lid portion 30 side) in a state where the main body portion 11 and the lid portion 30 are fitted. ) Is continuous with one end of the bent portion 40 via the first curved portion 41 that protrudes toward the upper end of the cover portion 30, and the connecting end side flange portion 37 in the lid portion 30 is fitted to the main body portion 11 and the lid portion 30. In this state, it is configured to be continuous with the other end of the bent portion 40 via a second curved portion 42 that is convex toward the inward side (main body portion side). That is, as shown in FIG. 7, the first bending portion 41 and the second bending portion 42 are both formed to bend in directions different from the bending portion 40.

The radius of curvature R1 of the first curved portion 41 and the radius of curvature R2 of the second curved portion 42 may be the same or different from each other. It is preferable that the radius of curvature of the portion 40 is greater than R0.
Moreover, the magnitude | size of the curvature radius R1 of the 1st curved part 41 and the magnitude | size of the curvature radius R2 of the 2nd curved part 42 are the material and thickness of the resin sheet which comprises the blister pack 10 for stool collection pipes, for example. In the relationship, it is preferable that the opening angle in the open state is 45 ° to 90 °. Here, the “open angle” is an angle formed by a plane including the opening end surface of the stool collection tube receiving recess 20 in the main body 11 and a plane including the inner surface of the flange portion 35 in the lid 30.
By adopting such a configuration, it becomes easier to automate the process of taking out the stool collection tube 50 at the time of inspection of the stool sample.
For example, when a configuration example in the case where a PET resin sheet having a thickness of 0.25 mm is used, the curvature radius R0 of the bent portion 40 is, for example, 2 mm, and the curvature radius R1 of the first curved portion 41 and The curvature radius R2 of the second curved portion 42 is, for example, 5 mm.

  The stool collection blister pack 10 described above is used by being set in an inspection machine while the stool collection pipe 50 is housed inside, and is opened by a lid opening jig in the inspection machine. At the same time, the stool collection tube 50 is removed from the stool collection tube blister pack 10 by the stool collection tube removal jig.

Thus, according to the blister pack 10 for a stool collection tube having the above configuration, when the lid 30 is opened by the spring properties of the first curved portion 41 and the second curved portion 42, the lid 30 is Since the open state can be maintained at an angle of a predetermined size, a state in which the stool collection tube 50 is easily taken out from the stool collection tube receiving recess 20 can be obtained. Further, the spring properties of each of the first curved portion 41 and the second curved portion 42 and the spring property of the bent portion 40 can be obtained without completely releasing the engaged state between the main body portion 11 and the lid portion 30. Thus, the lid 30 is opened so as to jump up, so that it can be easily opened. Therefore, it becomes easy to automate the process of taking out the stool collection tube 50 when inspecting the stool sample.
In addition, the function of the packaging form itself called “blister package”, specifically, the material or structure has sufficient strength to withstand transportation, and has a sealing property, so that the transportation bag can be made as in the past. It is possible to avoid the occurrence of problems during transportation of the stool collection tube 50 as long as the packaging form is used.

  In the blister pack 10 for a stool collection tube having the above-described configuration, the open / close end side flange portion 16 in the main body portion 11 is in the state where the main body portion 11 and the lid portion 30 are fitted to each other. Inclined so as to expand outward in the longitudinal direction with respect to the portion 36, and the open / close end is always open when the lid 30 is closed. For this reason, the lid 30 can be opened only by inserting an appropriate flat-plate-shaped lid opening jig into the opening / closing end side gap, so that the stool collection tube 50 can be taken out when the stool sample is inspected. It becomes easier to automate the process.

  Furthermore, the protrusion 38 is formed on the inner surface of the open / close end flange portion 36 of the lid 30, so that the open / close end flange portion 16 of the main body 11 and the open / close end flange portion 36 of the lid 30 are formed. Therefore, the space for inserting the lid opening jig can be reliably secured.

  Furthermore, in the blister pack 10 for the stool collection tube described above, the second concave portion 22 constituting the stool collection tube housing portion 20 in the main body portion 11 is configured so that one end side portion in the length direction is the outer shape of the cap 52 of the stool collection tube 50. The other end side portion has a space shape that matches the outer shape of the stool collection tube main body 51 of the stool collection tube 50. Further, the inner wall on the connection end side of the convex portion 31 of the lid portion 30 has a curved shape along the spherical surface related to the other end portion of the stool collection tube main body 51. For this reason, reverse insertion of the stool collection tube 50 with respect to the stool collection blister pack 10 can be reliably prevented. Accordingly, if the direction of the blister pack 10 for stool collection is aligned, the direction of the stool collection tube 50 can be aligned, so that it is easier to automate the process of taking out the stool collection tube 50 when testing a stool sample. .

  Furthermore, the second recess 22 constituting the stool collection tube receiving portion 20 in the main body 11 is configured such that the wall surface of the second recess 22 and the stool collection tube 50 in a state where the stool collection tube 50 is held in the second recess 22. It is set as the structure which has the bulging part 26 which forms the space S between this and the outer peripheral surface. For this reason, since the space S can be used as a space for inserting a stool collection tube jig, it is easier to automate the process of removing the stool collection tube 50 when inspecting a stool sample. Become.

  Furthermore, in the stool collection blister pack 10 described above, the convex portion 31 of the lid portion 30 is configured in a rectangular frame shape that matches the opening shape of the stool collection tube housing concave portion 20 of the main body portion 11. Sufficient strength to withstand the transportation of the blister pack 10 for the stool collection tube can be ensured in the lid 30, and the stool collection tube 50 is prevented from falling off due to the lid 30 being unexpectedly opened. In addition, since a relatively large flat surface area on the outer surface of the lid 30 can be secured, it becomes difficult to fill in the necessary information such as the name of the subject on the label attached to the outer surface of the lid 30. It is possible to avoid the occurrence of defects.

As mentioned above, although one Embodiment of the blister pack of this invention was described, this invention is not limited to said embodiment, A various change can be added.
For example, in the stool collection blister pack described above, each of the main body portion 11 and the lid portion 30 is configured to be continuous with the bent portion 40 via the curved portions 41 and 42, but the main body portion 11 and the lid portion 30. At least one of these may be configured to be continuous with the bent portion 40 via the curved portion.
