First, with reference to FIGS. 1 to 5, the structures of the binding container 1, the binding tool 5, and the mounting table 3 according to the present embodiment will be described.

As shown in FIGS. 1 to 5, the bundled container 1 includes a plurality of container bodies 2, a mounting table 3 on which the plurality of container bodies 2 are mounted, and a plurality of containers mounted on the mounting table 3. A binding band 4 that binds the plurality of container bodies 2 by covering the main body 2 is provided. The binding tool 5 is composed of the mounting table 3 and the binding band 4 among them.

As shown in FIGS. 1 to 4, the container main body 2 is for containing a chemical solution 26, and has a cylindrical body portion 23, and a mouth portion 21 and a bottom portion 22 located in the axial direction of the body portion 23. have. An end portion of the body portion 23 near the mouth portion 21 is provided with an inclined shoulder portion 23a. 4, illustration of the chemical solution 26 is omitted (the same applies to FIGS. 10 to 15 described later).

The container body 2 is a bottomed cylindrical vial made of, for example, borosilicate glass. The shape of the container body 2 is not particularly limited to a bottomed cylindrical shape, and may be, for example, a bottomed square tube shape.

The number of container bodies 2 is not particularly limited, and may be any number as long as it is plural. The bundled container 1 according to the present embodiment is provided with two container bodies 2, and these two container bodies 2 are arranged in a state in which their trunk portions 23 are in contact with each other. When three or more container bodies 2 are provided, one container body 2 and the adjacent container body 2 may be arranged with their trunk portions 23 in contact with each other. .

A sealing member 24 for sealing a chemical solution 26 is provided in the mouth portion 21 so as to close the opening of the mouth portion 21 . The upper end portion of the sealing member 24 is covered with a mouth cover 25 , and the lower end of the mouth cover 25 is engaged with the flange of the mouth 21 . With this configuration, it is possible to prevent the sealing member 24 from falling off from the opening 21 before the container body 2 is unsealed.

The material of the sealing member 24 can be composed of various elastic materials, for example, various rubbers such as butyl rubber, fluorine ETFE, and silicon rubber. The material of the mouth cover 25 is not particularly limited, but may be various metal materials, resin materials, or the like.

The mounting table 3 is made of a substantially flat plate-like member and has a top surface 31 , a bottom surface 32 and a peripheral surface 33 . The plurality of container bodies 2 described above are mounted on the mounting table 3 so that the bottom portions 22 of the respective container bodies 2 are in contact with the top surface 31 of the mounting table 3 . 22 will be protected by the mounting table 3 .

As shown in FIG. 5, the size and shape of the mounting table 3 in plan view are sufficient for stably mounting the plurality of container bodies 2 thereon. Specifically, in the present embodiment, the shape of the mounting table 3 in plan view is a track shape because two container bodies 2 are placed side by side. In addition, regarding the size of the mounting table 3 when viewed from above, the size in the long axis direction is substantially the same as the sum of the diameters of the bottom portions 22 of the two container bodies 2, and the size in the short axis direction The diameter is approximately the same as the diameter of the bottom portion 22 of each of the two container bodies 2 .

That is, in the binding container 1 according to the present embodiment, when viewed from above (that is, when viewed along the normal direction of the top surface 31), the portion that contacts and is covered with the binding band 4 The contour line of the mounting table 3 in the portion corresponding to the trunk portion 23 of each of the plurality of container bodies 2 is in contact with the binding band 4 and is covered with the trunk portion 23 of each of the plurality of container bodies 2. It is configured so as to overlap with the outline.

It should be noted that the size and outer shape of the mounting table 3 in plan view can be appropriately changed according to the arrangement, number and shape of the plurality of container bodies 2 .

On the other hand, the thickness of the mounting table 3 is not particularly limited as long as the bottom portion 22 of the container body 2 can be protected, but is preferably 1 mm or more and 10 mm or less.

The material of the mounting table 3 is not particularly limited, but may be various resin materials such as ABS resin.

Here, as shown in FIGS. 3 to 5, the top surface 31 of the mounting table 3 is provided with a concave portion 31a in at least part of the portion facing the bottom portion 22 of each of the plurality of container bodies 2. ing. The outer shape of the concave portion 31a in plan view is a track shape with a constriction in the central portion in the longitudinal direction.

Thus, by providing the recess 31a at a predetermined position on the top surface of the mounting table 3, even if one or both of the plurality of container bodies 2 are damaged (for example, cracked or chipped), Leakage of the liquid medicine 26 contained in the plurality of container bodies 2 to the outside of the bundled container 1 can be effectively suppressed. That is, since the liquid medicine 26 leaking from one or both of the plurality of container bodies 2 is received by the concave portion 31a, it is possible to prevent the drug liquid from immediately leaking out of the bundled container 1. FIG.

Further, when the outer shape of the recessed portion 31a when viewed from above is configured to have a constricted shape as described above, the volume of the recessed portion 31a can be secured while the portion abutting on the bottom portion 22 of each of the plurality of container bodies 2 can be reduced. It is also possible to secure the area of the top surface 31 of the mounting table 3 . As a result, the plurality of container bodies 2 can be stably mounted on the mounting table 3 while preventing leakage of the chemical solution 26 from the bundled container 1 .

The outer shape, size and depth of the concave portion 31a are not particularly limited, and can be appropriately changed according to the outer shape and size of each of the plurality of container bodies 2 .

The mounting table 3 protrudes toward the side opposite to the side where the bottom surface 32 of the mounting table 3 is located, and has a protrusion 31b extending along the edge of the top surface 31 of the mounting table 3. are doing. The inner peripheral surface of the ridge portion 31 b has a curved shape along the edge of the bottom portion 22 of the container body 2 .

The peripheral surface 33 of the mounting table 3 includes two inclined surfaces with different inclination angles. Both of these two slanted surfaces have a shape cut toward the inside of the mounting table 3, so that the peripheral surface 33 is provided with a cover configured so that the binding band 4 can be locked. A locking portion 33a is provided.

Of the two inclined surfaces described above, the upper inclined surface is inclined with respect to the normal direction of the mounting table 3, and the lower inclined surface is inclined with respect to the normal direction. In contrast, the degree of inclination is small. By configuring in this way, not only can the engaged portion 33a be provided on the peripheral surface 33, but also the peripheral surface is formed by one inclined surface that is inclined with respect to the normal line direction of the mounting table 3. The area of the bottom surface 32 can be increased as compared with the case where the bottom surface 32 is formed. Therefore, by configuring in this way, the binding container 1 can be placed in a more stable state.

The locked portion 33a may be provided on at least a part of the peripheral surface 33 along the circumferential direction of the peripheral surface 33. However, when the mounting table 3 is viewed from above, the locked portion 33a is arranged so as to sandwich the top surface 31 therebetween. are preferably provided at two or more locations on the peripheral surface 33 . In this embodiment, the engaged portion 33a is provided along the entire circumference of the peripheral surface 33 in the circumferential direction.

In addition, the position of forming the engaged portion 33a in the normal direction of the top surface 31 is not particularly limited, but the engaged portion 33a is provided at a portion of the peripheral surface 33 near the top surface 31. In this case, the binding band 4 required for manufacturing the binding container 1 can be made smaller. , the binding bands 4 can more firmly fix the plurality of container bodies 2 and the mounting bases 3 .

As shown in FIGS. 1 to 4, the binding band 4 binds the plurality of container bodies 2 by covering the plurality of container bodies 2 placed on the mounting table 3. configured as follows. The tying band 4 is provided so as to encircle the plurality of container bodies 2 so as to be arranged inside thereof, and is in contact with and covers a portion of the body portion 23 of each of the plurality of container bodies 2. , and bundles the plurality of container bodies 2 .

Here, the term "heat-shrinkable film" refers to a flexible film that shrinks when heated to a predetermined temperature (for example, 70° C. or higher and 120° C. or lower) (heat shrinkability).

The binding band 4 made of a heat-shrinkable film is obtained by forming the heat-shrinkable film into a tubular shape with one direction (main heat-shrinking direction) of the heat-shrinkable film as the circumferential direction. The binding band 4 shrinks greatly in the circumferential direction when heated to a temperature of, for example, 70° C. or higher and 120° C. or lower.

The heat-shrinkable film has flexibility and is heat-shrinkable in at least one direction (the one direction is the circumferential direction when formed into a cylindrical shape). can be anything. A heat-shrinkable film is obtained by forming a film of a material containing a resin component, stretching it in at least one direction, and then heat-aging it at a predetermined temperature.

As the heat-shrinkable film, a film slightly heat-shrinkable or heat-extensible in the other direction different from the one direction may be used. The other direction is preferably a direction orthogonal to the above one direction in the film plane.

The material constituting the heat-shrinkable film is not particularly limited, but examples include polyester resins such as polyethylene terephthalate, olefin resins such as polypropylene, polystyrene resins such as polystyrene, cyclic olefin resins, poly Examples thereof include resin compositions containing, as a main component, one or a mixture of two or more selected from biodegradable resins such as lactic acid and thermoplastic resins such as vinyl chloride resins. Moreover, the heat-shrinkable film may be of a single layer or may be composed of a laminate of two or more layers.

The thickness of the binding band 4 is not particularly limited, but can be, for example, 20 μm or more and 200 μm or less. The binding band 4 may be provided with optional layers such as a design printed layer, a surface protective layer, and a sliding layer, if necessary.

The size of the binding band 4 in the state before heat shrinking may be any size as long as it can bind a plurality of container bodies 2 by heat shrinking. It is appropriately adjusted according to the size of the stand 3 . Specifically, the axial length of the banding band 4 before being thermally shrunk is the same as at least a part of the trunk portion 23 of each of the plurality of container bodies 2 and the mounting table 3 after being thermally shrunk. It is sufficient that it has a length that can cover at least a part of the locked part 33a of the container body 2 and at least a part of the shoulder part 23a of each of the plurality of container bodies 2 and the locked part of the mounting table 3 It is even better if it has a length that can cover at least part of 33a.

Here, as shown in FIGS. 1 to 3, the binding band 4 in the state after being thermally shrunk extends upward so as to reach the shoulder 23a of the container body 2, and the shoulder 23a extends upward. The portion reaching 23a is contracted inward. As a result, the binding band 4 is locked to the shoulder portion 23a.

Further, as shown in FIGS. 1 to 4, the binding band 4 in the state after being thermally shrunk extends downward so as to reach the engaged portion 33a of the mounting table 3. The portion reaching the stop portion 33a is contracted inward. As a result, the binding band 4 is locked to the locked portion 33a.

When configured in this manner, the bundled container 1 can be produced with high production efficiency, the details of which will be described later.

The film used as the binding band 4 is not limited to the heat-shrinkable film described above, and a self-shrinkable film (stretch film) may be used instead. Self-elasticity refers to the property (self-elasticity) of expanding by being pulled and returning to substantially the original shape when the tensile force is released. Furthermore, as the film used as the binding band 4, a film having heat-shrinkability and self-stretchability may be used.

6 to 9 are schematic cross-sectional views showing the method of manufacturing the bundled container according to this embodiment. Next, an example of a specific manufacturing method for manufacturing the bundled container 1 according to the present embodiment described above will be described with reference to FIGS. 6 to 9. FIG.

First, as shown in FIG. 6, a mounting table 3 for binding a plurality of container bodies 2 is prepared, and the mounting table 3 is arranged on a work table or the like (not shown).

Next, as shown in FIG. 7, a plurality of container bodies 2 are mounted on the mounting table 3 . Specifically, a plurality of container bodies 2 are mounted on the mounting table 3 so that each bottom portion 22 abuts the top surface 31 of the mounting table 3 .

Here, as described above, the mounting table 3 has the protrusion 31b extending along the edge of the top surface 31 of the mounting table 3, and the inner peripheral surface of the protrusion 31b is It has a curved shape along the edge of the bottom 22 of the container body 2 .

Therefore, by configuring in this way, when placing a plurality of container bodies 2 on the mounting table 3, the adhesion between the bottom portion 22 of each of the plurality of container bodies 2 and the mounting table 3 is improved. As a result, the plurality of container bodies 2 can be mounted on the mounting table 3 in a more stable state.

Furthermore, in the case of such a configuration, it is possible to effectively prevent the plurality of container bodies 2 from being displaced so as to protrude from the mounting table 3 . That is, even when a plurality of container bodies 2 are arranged so as to protrude from the mounting table 3, the protrusions 31b having a curved shape on the inner peripheral surface can place the plurality of container bodies 2 thereon. It will be returned toward the inside of the stand 3 and will function as a guide for positioning the plurality of container bodies 2 .

Next, as shown in FIG. 8, the binding band 4 is positioned and arranged with respect to the mounting table 3 and the plurality of container bodies 2 mounted on the mounting table 3 . Specifically, a cylindrical banding band 4 is positioned and arranged so that the plurality of container bodies 2 and mounting bases 3 are housed in the inner space thereof.

At this time, the binding band 4 covers at least a portion of the shoulder portion 23a of each of the plurality of container bodies 2 and at least a portion of the engaged portion 33a of the mounting table 3 in a state in which a heat shrinking process to be described later is performed. Its axial position is adjusted so that it is different.

Here, as described above, when viewed along the normal direction of the top surface 31 of the mounting table 3, each of the plurality of container bodies 2 in the portion that comes into contact with and is covered with the binding band 4 The contour line of the mounting table 3 in the portion corresponding to the trunk portion 23 overlaps the contour line of each trunk portion 23 of each of the plurality of container bodies 2 in contact with and covered by the binding band 4. , it becomes unnecessary to increase the size of the binding band 4 more than necessary, and the binding band 4 can be made sufficiently small. Therefore, with this configuration, it is possible to reduce the amount of material used for the binding band 4 and reduce the manufacturing cost.

Furthermore, in the case of such a configuration, the amount of heat input required for thermally shrinking the binding band 4 can be reduced. It is also possible to effectively reduce the risk that the heat for heat shrinking will have an adverse effect.

From the viewpoint of reducing the amount of material used for the binding band 4 and preventing the heat for thermally shrinking the binding band 4 from adversely affecting the quality of the chemical liquid 26, the top surface 31 of the mounting table 3 is When viewed along the normal direction, the contour line of the mounting table 3 at the portion corresponding to the body portion 23 of each of the plurality of container bodies 2 that comes into contact with and is covered with the binding band 4 is Alternatively, the container body 2 may be positioned inside the outline of the body portion 23 of each of the plurality of container bodies 2 at the portion that comes into contact with and is covered with the binding band 4 .

Further, in this embodiment, since the mounting table 3 has the engaged portion 33a on the peripheral surface 33 thereof, the binding band 4 is long enough to reach the bottom surface 32 of the mounting table 3 at its lower end. As described above, it is sufficient that the lower end has a length that covers at least part of the locked portion 33a. Therefore, it becomes unnecessary to make the binding band 4 larger than necessary, and the binding band 4 can be made sufficiently small.

Therefore, with this configuration, the amount of material used for the binding band 4 can be reduced, the manufacturing cost can be reduced, and the quality of the chemical solution 26 contained in the plurality of container bodies 2 can be improved. It is also possible to effectively reduce the risk that the heat for heat shrinking will have an adverse effect.

Next, the binding band 4 is heated to be thermally shrunk. Specifically, for example, the binding band 4 that has been thermally shrunk by being blown with hot air using a shrink heater (a heating device that shrinks the film with hot air or the like) or the like is at least the shoulder portion 23a of each of the plurality of container bodies 2. A part of the mounting table 3 is brought into close contact with at least a part of the locked portion 33a of the mounting table 3 so as to be locked thereto. At this time, by blowing the hot air, the banding band 4 is brought into close contact with a portion of the body portion 23 of each of the plurality of container bodies 2 as well.

As a result, as shown in FIGS. 1 to 4, the plurality of container bodies 2 are bound while being placed on the mounting table 3. At the same time, the plurality of container bodies 2 and the mounting table are bound together. 3 are fixed by the binding band 4 .

In the above description, a case in which hot air is blown over the entire surface of the binding band 4 has been described as an example. , the hot air may be blown only to the portions corresponding to the shoulder portions 23a of each of the plurality of container bodies 2 and the engaged portions 33a of the mounting table 3 among them.

Here, the temperature of the hot air is, for example, 70° C. or higher and 120° C. or lower in consideration of the heat shrinkage temperature of the binding band 4, but the type of the chemical solution 26 and the types and thicknesses of the plurality of container bodies 2 are taken into consideration. can be changed as appropriate. Moreover, the temperature of the hot air can be lowered by lengthening the blowing time of the hot air.

In place of the hot air described above, the banding band 4 may be shrunk by irradiating infrared rays or by pressing the banding band 4 with a jig or the like whose surface is heated, thereby shrinking the plurality of container bodies 2 . The plurality of container bodies 2 and the mounting table 3 may be fixed to each other by the binding band 4 while being bound on the mounting table 3 .

In addition, when the self-shrinkable self-shrinkable film described above is used as the binding band 4 instead of the heat-shrinkable film, the above-described mounting table 3 and the plurality of container bodies mounted on the mounting table 3 In the step of positioning and arranging the binding band 4 with respect to 2, the cylindrical binding band 4 having an inner circumference length in the original state smaller than that of the plurality of container bodies 2 and mounting tables 3 arranged side by side is It is positioned and placed in an expanded state by a pulling mechanism or the like. Further, instead of the above-described process of thermally shrinking the binding band 4, a step of releasing the tensile force by the above-described pulling mechanism or the like is performed, so that the binding band 4 returns to its original shape, thereby allowing the binding band 4 to By closely contacting at least a portion of the shoulder portion 23a of each of the plurality of container bodies 2 and at least a portion of the locked portion 33a of the mounting table 3, the container is locked.

Through the steps described above, the bundled container 1 according to the present embodiment described above is manufactured.

Here, before the step of placing a plurality of container bodies 2 on the mounting table 3 described above (see FIG. 7), a binding tool 5 as shown in FIG. 9 may be prepared. The tying tool 5 is for tying a plurality of container bodies 2 together, and includes the mounting table 3 and the tying band 4 described above. Specifically, in the binding tool 5 , the binding band 4 is provided so as to surround the space above the mounting table 3 . A space for housing is provided in advance on the mounting table 3 .

The binding tool 5 may be configured by temporarily fixing the mounting table 3 and the binding band 4 with an adhesive or the like. It may be just positioned and held.

By accommodating a plurality of container bodies 2 in the above-described space of the binding device 5 constructed in this manner, a plurality of container bodies 2, mounting bases 3 and binding bands 4 configured as shown in FIG. 8 are obtained. In this state, the binding band 4 is further thermally shrunk, so that the above-described binding container 1 according to the present embodiment can be manufactured.

In the binding container 1 according to the present embodiment described above, the binding band 4 for binding the plurality of container bodies 2 mounted on the mounting table 3 is attached to the mounting table 3 as described above. The engaged portion 33a extends to reach the engaged portion 33a provided on the peripheral surface 33 of the ring, and contracts inwardly at the portion reaching the engaged portion 33a. is locked to Therefore, when the binding band 4 is thermally shrunk and its lower end is locked to the mounting table 3 , the binding band 4 does not need to be locked to the bottom surface 32 of the mounting table 3 . and the mounting table 3 are not required to be lifted from the work table or the like.

Therefore, by using the binding container 1, the binding tool 5, and the mounting table 3 according to the present embodiment, the binding container 1 can be produced with high production efficiency.
