Description

  The present invention relates to a drug bottle containing a drug such as a solid dialysis agent used for preparing a dialysate used for artificial dialysis.

  There are two types of dialysis agents, liquid and solid. Most liquid-type dialysis agents are occupied by water, and the weight and capacity of the liquid-type dialysis agent are large. Therefore, the load of transportation work for dialysis medical workers is large, and the storage space is also large. Therefore, in recent years, when using dialysate, a solid-type dialysis agent (hereinafter referred to as solid dialysis agent), which is introduced into an automatic dissolution apparatus and dissolved in water to prepare a dialysis solution, has rapidly spread. ing.

  Currently, there are two types of containers for storing solid dialysis agents: bag type and bottle type. A technique related to a bag-type container for storing a solid dialysis agent is disclosed in, for example, Japanese Patent Application Laid-Open No. 2006-136615 (Patent Document 1).

JP 2006-136615 A

  The bottle-type container that contains the solid dialysis agent is made of a material that is more rigid than the bag-type container, so it is difficult to reduce the volume of the container by crushing the container after use and discarding it. There is a problem that it is sometimes bulky.

  The objective of this invention is providing the chemical | medical agent bottle which can reduce the volume after use easily, ensuring rigidity.

  The drug bottle of the present invention includes a bottle body, a first mouth portion formed at the upper end of the bottle body, and a second mouth portion formed at the lower end of the bottle body. The bottle body is formed with a groove that is recessed toward the inside of the bottle body and extends in the vertical direction. The groove has a bottom. In the cross section perpendicular to the vertical direction of the bottle body, the thickness of the cross section at the bottom is larger than the thickness of the cross section at the position farthest from the center of gravity of the cross section perpendicular to the vertical direction of the bottle body.

  In the above-described drug bottle, the bottom of the groove that is recessed toward the inside of the bottle body constitutes a column-like portion extending in the vertical direction. Thereby, since the rigidity of the up-down direction of a medicine bottle becomes large, the deformation | transformation in use of a medicine bottle can be suppressed. Since the drug bottle can be easily crushed starting from a portion having a small thickness away from the center of gravity, the volume of the drug bottle after use can be easily reduced.

  The bottom portion extends in the vertical direction from the upper end of the groove to the lower end of the groove. Since the bottom of the thick groove extends to the vicinity of the first mouth and the second mouth, the rigidity of the portion near the first mouth and the second mouth increases, so the deformation of the drug bottle is further suppressed. can do.

  The shape of the groove in the cross section orthogonal to the vertical direction of the bottle body includes an arc-shaped portion. Thereby, since a chemical | medical agent bottle can be shape | molded easily, productivity improves.

  The cross section perpendicular to the vertical direction of the bottle body is substantially rectangular. The groove is formed on the long side of the substantially rectangular cross section. Thereby, a thick bottom part can be constituted easily and reliably.

  The groove has a first groove and a second groove. The first groove and the second groove are formed to face each other across the center of gravity of the cross section perpendicular to the vertical direction of the bottle body. Thereby, since the rigidity in the vertical direction of the drug bottle is further increased, deformation of the drug bottle can be more reliably suppressed.

The body portion 8 has a pair of first wall surfaces 11 and a pair of second wall surfaces 12. The first wall surface 11 and the second wall surface 12 extend in the up-down direction DR1. The first wall surface 11 is a wall surface constituting the long side of a substantially rectangular cross section orthogonal to the vertical direction DR1 of the body portion 8.

<Method for forming drug bottle 1>
The drug bottle 1 of the present invention is formed by blow molding. Blow molding is a method of forming a hollow resin product by sandwiching a parison (tubular thermoplastic resin) with a mold, closing the top and bottom of the parison, blowing air, and pressing the parison against the inner surface of the mold. . In blow molding, the parison swells like a balloon around the parison. The parison in contact with the mold at a position closer to the axis starts to harden more quickly. Therefore, the wall thickness at a position closer to the axial center in the bottle body 2 is larger than the thickness at a position away from the axial center in the bottle body 2. As a result, in the drug bottle 1 of the present embodiment, the thickness of the bottom portion 17 located near the center of gravity G is increased, and the thickness at a position away from the center of gravity G is decreased.

  As described above, the distance a shown in FIG. 5 is larger than the radius r1 of the liquid inlet 6 shown in FIG. The distance a shown in FIG. 5 is larger than the radius r2 of the liquid discharge port 7 shown in FIG. Thus, by determining the dimension of the bottle main body 2, it can suppress that the parison before expansion contacts a metal mold | die.

<How to use drug bottle 1>
FIG. 8 is a schematic view showing a state in which the medicine bottle 1 is attached to the automatic dissolution apparatus 100. The automatic dissolution apparatus 100 is attached to a dialysis apparatus. The automatic dissolution apparatus 100 sandwiches the drug bottle 1 from above and below. The medicine bottle 1 has a medicine (for example, baking soda) inside. The automatic dissolving apparatus 100 supplies a dissolving liquid (for example, RO water) into the medicine bottle 1. The solution passes through the filter, passes through the liquid inlet 6, and is supplied to the drug bottle 1. In the drug bottle 1, a saturated solution of the drug and the solution is prepared. The saturated solution passes through the filter through the liquid outlet 7 and is discharged to the dialyzer.

  The medicine bottle 1 suppresses deformation during use of the automatic dissolution apparatus 100 and prevents the medicine bottle 1 from being detached from the automatic dissolution apparatus 100 during use. When the drug bottle 1 is discarded after use, the bottle main body 2 is easily deformed and thus is not bulky. A small groove 13 is formed in the bottle body 2. The small groove 13 has a shape that is recessed toward the inside of the bottle body 2. The small groove 13 allows the bottle body 2 to be more easily deformed.

<Effect>
It is as follows when the effect of the medicine bottle 1 of embodiment is demonstrated collectively. In addition, although a reference number is attached | subjected to the structure of embodiment, this is an example.

  As shown in FIGS. 1 and 2, the drug bottle 1 of the present embodiment includes a bottle main body 2, a first mouth portion 3, and a second mouth portion 4. The bottle body 2 is formed with a groove 14 extending in the vertical direction DR1 that is recessed toward the inside of the bottle body 2. The groove 14 has a bottom 17. The thickness of the cross section orthogonal to the vertical direction DR1 at the bottom 17 is larger than the thickness of the cross section orthogonal to the vertical direction DR1 at the position farthest from the center of gravity G.

  The drug bottle in which the groove 14 is not formed may be detached from the automatic dissolution apparatus 100 due to deformation during use of the automatic dissolution apparatus 100, particularly deformation immediately after use of the automatic dissolution apparatus 100. In the drug bottle 1 in which the groove 14 of the present embodiment is formed, the bottom portion 17 of the groove 14 that is recessed inward constitutes a column-like portion extending in the vertical direction DR1. Since the thickness of the cross section perpendicular to the vertical direction DR1 at the bottom portion 17 is large, the portion like a column has high rigidity. Thereby, since the rigidity of the up-down direction DR1 of the medicine bottle 1 is increased, deformation of the medicine bottle 1 during use of the automatic dissolution apparatus 100 is suppressed, and the medicine bottle 1 is prevented from being detached from the automatic dissolution apparatus 100.

  While the thickness of the bottom portion 17 near the center of gravity G increases, the thickness of the bottle body 2 decreases at a position away from the center of gravity G in the bottle body 2 and the rigidity decreases. For this reason, since the bottle main body 2 can be easily deformed starting from a portion having a small wall thickness, the medicine bottle 1 can be easily crushed and not bulky when the medicine bottle 1 is discarded after use. .

  Thus, by providing a difference in the wall thickness of the bottle body 2, it is possible to realize the drug bottle 1 that can easily reduce the volume after use while ensuring rigidity.

  As shown in FIG. 1, the bottom 17 extends in the vertical direction DR <b> 1 from the upper edge 15 to the lower edge 16. Since the bottom portion 17 of the thick groove 14 extends to the vicinity of the first mouth portion 3 and the second mouth portion 4, the rigidity of the portions close to the first mouth portion 3 and the second mouth portion 4 is increased. The deformation of the bottle 1 can be further suppressed.

  As shown in FIG. 5, the groove 14 in the cross section perpendicular to the vertical direction DR1 of the bottle body 2 has an arc shape. The shape of the groove 14 may be arbitrary, for example, may be V-shaped. However, by making the groove 14 arcuate, manufacturing becomes easy and productivity is improved.

  The cross section perpendicular to the vertical direction DR1 of the bottle body 2 is substantially rectangular, and a groove 14 is formed on the long side of the substantially rectangular cross section. The gravity center G and the bottom portion 17 in the cross section perpendicular to the vertical direction DR1 of the bottle body 2 are close to each other. In the blow molding described above, the thickness of the portion close to the axial center in the bottle body 2 is increased. Therefore, since the thickness t1 of the cross section perpendicular to the vertical direction DR1 at the bottom portion 17 located near the center of gravity G can be increased, the thick bottom portion 17 can be easily and reliably configured.

  The grooves 14 are formed as a pair facing each other with the center of gravity G interposed therebetween. When the groove 14 is formed only at one place, the portion facing the groove 14 and the center of gravity G is easily deformed. Since the grooves 14 are formed as a pair facing each other across the center of gravity G, the rigidity of the drug bottle 1 in the vertical direction DR1 is further increased, so that the deformation of the drug bottle 1 can be more reliably suppressed.

(Thickness difference of bottle body 2)
The drug bottle 1 according to the embodiment is manufactured, and in the bottle body 2, the thickness t1 (FIG. 6) at the bottom 17 located near the center of gravity G and the thickness t2 at the position farthest from the center of gravity G (FIG. 7). And measured. A dial gauge was used for measurement. Table 1 shows the thickness measurement results of the bottle body 2 of the two drug bottles 1 (No. 1 and No. 2).

  As a comparative example, a drug bottle in which no groove was formed in the bottle body was produced, and the thickness of the portion near the center of gravity and the thickness of the portion away from the center of gravity were measured in the bottle body. A dial gauge was used for measurement. Table 2 shows the wall thickness measurement results on the bottle bodies of two drug bottles (No. 1 and No. 2) in which grooves are not formed.

  From Table 1 and Table 2, it can be seen that the difference between the thickness of the portion closer to the center of gravity and the thickness of the portion away from the center of gravity is larger in the bottle body 2 in which the groove 14 of the embodiment is formed. .

(Change in length of drug bottle)
The medicine bottle 1 of the embodiment and the medicine bottle in which the groove of the comparative example is not formed are respectively attached to the automatic dissolution apparatus 100, and the upper and lower treatments sandwiching the medicine bottle before and immediately after use of the automatic dissolution apparatus 100 are performed. The spacing of the tools was measured. Table 3 shows the change in the distance between the jigs before and immediately after use of the automatic dissolution apparatus 100 when the chemical bottles 1 (No. 1 and No. 2) of the two embodiments are used in the automatic dissolution apparatus 100. Indicates the amount. Table 4 shows the amount of change in the interval between the jigs before and immediately after use of the automatic dissolution apparatus 100 when the chemical bottles (No. 1 and No. 2) of two comparative examples are used in the automatic dissolution apparatus 100. Show.

  As shown in Table 4, when the drug bottle of the comparative example in which no groove is formed is used in the automatic melting apparatus 100, the interval between the jigs is reduced immediately after use, that is, the comparative example in which no groove is formed. The drug bottle had contracted immediately after use. This is because the drug bottle in which no groove is formed has a small rigidity in the vertical direction DR1.

  On the other hand, as shown in Table 3, when the drug bottle 1 according to the embodiment in which the groove 14 was formed was used in the automatic dissolution apparatus 100, it did not shrink immediately after use of the automatic dissolution apparatus 100.

  Thus, by providing a difference in the thickness of the bottle body 2, the rigidity of the drug bottle 1 in the vertical direction DR1 can be increased, and deformation of the drug bottle 1 can be suppressed. It has been shown that it is possible to avoid a situation where the automatic dissolution apparatus 100 is disconnected during use.

  As a modification, the shape of the medicine bottle 1 may be cylindrical, elliptical, or polygonal. The small groove 13 may not be formed in the bottle body 2. The bottom portion 17 of the groove 14 may be formed so as not to extend over the upper edge portion 15 and the lower edge portion 16. For example, the groove 14 may be formed only in the body portion 8 of the bottle body 2.

  Although the embodiment of the present invention has been described as above, the embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
