Description

The present invention relates to a sealing method and a sealing structure suitable for a blister container made of a sheet-like resin.

Generally, a blister container made of a sheet-shaped resin is processed by vacuum forming or compressed air forming technology. The molded product is in the form of combining a receiving container for storing articles and a separately molded lid, or folding a receiving container and a lid integrally molded (commonly known as a shell pack) into two pieces. Then, in these sealed portions, hollow protrusions are integrally formed on the seat wall of the receiving container and the lid, respectively, and the other protrusion is overlapped with the one protrusion. That is, the outside of one protrusion is on the male side, and the inside of the other protrusion is on the female side so that the two fit together.

In such a blister container, an undercut by vacuum forming or pressure forming technique is adopted for the sealing portion between the receiving container and the lid. For example, by making the root side of the protruding portion narrower than the tip side, the fitting state of the male and female protruding portions is stabilized. As a result, the blister container can be easily sealed by simply fitting the protruding portions of the receiving container and the lid together.

On the other hand, when an article is packaged in such a blister container, there is a high possibility that impact, dropping, or intentional opening may occur only by the simple sealing as described above. In addition, when the article placed in the blister container is tampered with, there is no trace of whether or not the article has been opened, which makes the article packaging unreliable.

Therefore, conventionally, when sealing with a blister container, various measures for preventing tampering are implemented by a secondary step in addition to the primary step of fitting male and female protrusions.
For example, in the case of egg packs, the opening may be fastened with adhesive tape after simple sealing, or the opening may be heat-sealed to make a perforation on a part of the receiving container, and this part may be broken to open. ing. For lunch boxes, etc., tamper-proof measures are taken by wrapping the entire circumference of the opening with a film, attaching a sticker to the opening, and stapled.
Patent Document 1 is known as a conventional technique for a blister container made of a sheet-shaped resin.

Japanese Unexamined Patent Publication No. 2018-122868

However, according to such a conventional blister container sealing method, the primary process of fitting the male and female protrusions is often performed manually, and even if the subsequent secondary process is performed by a dedicated machine, it is dedicated. It takes time and effort to set the blister container and the packaging material on the machine. Further, when the opening of the blister container is heat-sealed, it takes time for heat welding of the sealed portion (usually, it takes about 10 to 15 seconds each time), so that the efficiency of the sealing work is deteriorated. Such problems become more pronounced when dealing with large volumes of containers.

Further, in the conventional blister container sealing method, when packaging materials such as tapes and seals are used in the secondary process, these packaging materials become dust at the time of opening. In recent years, there has been an increasing demand for reducing the amount of brass waste discharged, and suppressing the use of packaging materials is also effective as an environmental measure.

The present invention has been made in view of such a current situation, and an object thereof is to reduce the labor and time of the sealing work (secondary process) for preventing tampering as shown above, and also to reduce the time and effort of the tape or the seal. It is an object of the present invention to provide a sealing method and a sealing structure of a blister container which does not require a packaging material such as.

In order to solve the above problems, the present inventors have attempted to improve the position and shape of the sealed portion in the blister container. While repeating the sealing with various prototypes, we focused on the point of fusing the primary process of fitting the receiving container and the protruding part of the lid with each other and the secondary process of preventing tampering. Then, they have found that an appropriate retaining function can be realized by fitting the protruding portions of the receiving container and the lid together and simply sealing the seals, and then reworking the sealed portions by press molding. That is, the present invention is completed by press-molding the protruding portion (sealed portion) of the double sheet wall obtained in the primary step into a “mushroom-shaped (or anchor-shaped)” cross section as it is to form a retaining structure. It has reached.

The sealing portion is a flat cross-section mushroom-shaped seat wall in which the seat wall at the periphery of the through hole and the seat wall of the protruding portion overlap each other.
In addition, an annular cut portion (L: see FIG. 20) for partially separating the sealed portion from the sheet wall is provided at a position slightly away from the root of the sealed portion on the seat wall of the receiving container. It was configured to be.

(Effect of the 18th invention)
According to such a blister container sealing structure, when the stored article is taken out from the blister container, the receiving container and the lid are opened by separating the sealing portion from the sheet wall of the receiving container along the cut portion. As a result, the opening operation can be performed without separating the sealing portion (through hole and protruding portion).
Further, since the cut portion is provided at a position slightly distant from the root of the sealed portion on the sheet wall of the receiving container, the sealed portion is partially separated from the receiving container when the receiving container and the lid are opened. As a result, the materials of the receiving container and the lid can be efficiently separated and collected.
Further, since the sealed portion separated from the receiving container remains as it is in the through hole of the lid, it is possible to prevent the separated pieces of the sheet-shaped resin forming the sealed portion from scattering around at the time of opening.

(Inventions 1 to 18)
In the first to eighteenth inventions, the receiving container and the lid of the blister container may be formed separately or may be a shell type integrally connected.
Examples of the article to be stored in the blister container include various products, parts thereof, foods, chemicals and the like. In particular, it is effective when used for packaging screws, hooks, replacement needles, replacement blades, electronic parts, and the like. The type and number of articles are not limited as long as the effects of the present invention can be obtained. The size and shape of the blister container can be appropriately selected according to the articles to be stored.
An undercut may or may not be adopted for the sealed portion (first protruding portion and second protruding portion) of the blister container.
In addition, sealing portions are provided at a plurality of locations of the blister container, and the above steps 1A to 1D, 2A to 2D, 3A to 3D or 4A to 4D are performed on some of the sealing portions, and the remaining sealing portions are provided with sealing portions. Press molding by these steps may not be performed. By adopting such a sealing method, even if a part of the sealed portion is broken or crushed due to plastic deformation at the time of opening, the container can be resealed (simple sealing) by the remaining sealed portion.
It is also possible to simultaneously perform the step of forming the protrusion for sealing in the blister container and the step of press-molding the protrusion and sealing as described above.
The cut portion for separating the sealed portion of the blister container may be any as long as it promotes the breakage of the sheet wall when the receiving container and the lid are separated from each other. For example, a seat wall that has been processed by a half cut, a perforation cut, a slit, or the like can be used as a cut portion. Further, a cut portion may be formed by processing the thickness of the sheet wall to be extremely small along the cut portion (thin wall).
The inventions 1 to 18 may be combined with other inventions described in the present specification.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The technical scope of the present invention is not limited to the configuration of the following embodiment.
[First Embodiment]
The blister container 10 of the first embodiment is shown in FIG. In this embodiment, the present invention is applied to a shell-type blister container 10.
The blister container 10 is made of a transparent or translucent sheet-like resin, and is integrally formed by vacuum forming or compressed air forming. As shown in FIGS. 2 and 3, the upper container 2 and the lower container 3 are connected via a hinge 4. One corresponds to the receiving container of the present invention, and the other corresponds to the lid. When the upper container 2 is put on the lower container 3, the article M is stored between the two (see FIG. 3B).

The material of the blister container 10 is selected according to the size and use of the article M to be stored. For example, polyvinyl resin (PVC hard, PVC soft, PVDC, PVA), polystyrene resin (PS, AS, ABS, HDPE, LDPE, EVA), polypropylene, polyacetal, acrylic (PMMA, MS), cellulose acetate, Polycarbonate, polyethylene terephthalate, polyamide (nylon type), polyurethane, fluororesin (ethylene trifluoride, ethylene tetrafluoride, ethylene tetrafluoride, propylene hexafluoride copolymer, ethylene tetrafluoride / ethylene copolymer , Fluorinated vinylidene) and the like can be adopted. The sheet thickness is about 0.3 to 1 mm.

The blister container 10 is formed with an oval sealing portion 5 at a position opposite to the hinge 4 when viewed from a plane direction. In the sealed portion 5, the protruding portions 2c and 3c of the upper container 2 and the lower container 3 are processed into a mushroom-shaped cross section by press molding (see FIGS. 3 and 4). The shape of the sealed portion 5 keeps the upper container 2 and the lower container 3 from being easily opened, and prevents the blister container 10 containing the article M from being impacted, dropped, or intentionally tampered with.

As shown in FIG. 2, in the blister container 10 before sealing, the sheet-shaped upper container 2 and the lower container 3 are connected in a plane direction. The upper container 2 and the lower container 3 have a substantially vertically symmetrical relationship with the hinge 4 interposed therebetween.
The upper container 2 includes an upper accommodating portion 2a having a rectangular flat cross section and a U-shaped cross section, and an upper flange portion 2b connected to the outer periphery thereof. An upper tab 2d cut into a substantially trapezoidal shape is provided on the tip end side of the upper flange portion 2b, and a hollow upper protruding portion 2c having a flat oval shape is provided between the tab and the upper accommodating portion 2a.
The lower container 3 includes a lower accommodating portion 3a having a rectangular flat cross section and a U-shaped cross section, and a lower flange portion 3b connected to the outer periphery thereof. A lower tab 3d cut into a trapezoid is provided on the tip end side of the lower flange portion 3b, and a hollow lower protruding portion 3c having a flat oval shape is provided between the lower tab 3d and the lower accommodating portion 3a. ..
When the hinge 4 is bent and the upper container 2 and the lower container 3 are put together, the flange portions 2b and 3b of both are substantially overlapped with each other, and the storage openings of these containers are closed.

The upper protrusion 2c and the lower protrusion 3c are located at equal distances up and down from the hinge 4, and the size of the upper protrusion 2c is the same as or larger than the lower protrusion 3c. When the upper container 2 and the lower container 3 are put together, the outside of the lower protrusion 3c fits inside the upper protrusion 2c (see FIG. 3). That is, the inner wall of the sheet of the upper protruding portion 2c and the outer wall of the sheet of the lower protruding portion 3c are in a male-female relationship, and the blister container 10 is simply sealed.

As shown in FIG. 4, the sealed portion 5 after press molding is a double sheet wall having a mushroom-shaped cross section in which the sheet walls of the protruding portions 2c and 3c overlap each other (see FIG. 4B). The overlapping sheet walls are in close contact with each other and are not bonded or welded. When the upper protruding portion 2c and the lower protruding portion 3c are forcibly separated from each other, these double sheet walls are broken with plastic deformation.

The double sheet wall in the sealed portion 5 is connected to the lower wall 5A forming the leg portion having a mushroom-shaped cross section, the intermediate wall 5B which is connected to the lower wall 5A to form the umbrella portion having a mushroom-shaped cross section, and the intermediate wall 5B. It is provided with an upper wall 5C that forms an umbrella portion having a mushroom-shaped cross section.
The lower wall 5A bends from the flat sheet wall around the sealing portion 5 and continues to the intermediate wall 5B as it is. As a result, the height of the sealed portion 5 can be suppressed, and the sealed portion 5 can be made inconspicuous in the appearance of the blister container 10. Further, by lowering the height of the sealing portion 5, the plate thickness is reduced (especially the rising portion from the root) when the upper protruding portion 2c and the lower protruding portion 3c are drawn (vacuum forming or pneumatic forming) in the blister container 10. ) Can be suppressed, and the thickness of the double sheet wall of the sealing portion 5 can be finished more uniformly. Further, it is useful for saving the sheet material of the upper protrusion 2c and the lower protrusion 3c.
The intermediate wall 5B is inclined in a tapered shape so that the outer diameter expands toward the tip end side of the sealing portion 5, and the inclination angle is an appropriate angle (40 to 60) with respect to the flat seat surface on the root side. It is set to keep ゜). Since the intermediate wall 5B has a tapered inclination that expands upward in this way, a shearing force is generated on the double sheet wall of the intermediate wall 5B when the upper protrusion 2c and the lower protrusion 3c are separated from each other. It's getting easier.
The inclination angle of the intermediate wall 5B is set by the guide plate 17 in the sealing device 11 described later, but plastic deformation occurs when the sealing portion 5 (upper protrusion 2c, lower protrusion 3c) is pulled away. It is appropriately selected according to the sheet material and thickness.

Next, a sealing device 11 for press-molding the sealing portion 5 of the blister container 10 will be described. The sealing device 11 processes the sealed portion 5 of the simply sealed blister container 10 into a mushroom-shaped cross section.
As shown in FIG. 5, the sealing device 11 includes an upper mold 12 and a lower mold 13 for upward molding. In FIG. 5, the lower mold 13 is the fixed side and the upper mold 12 is the moving side, but these may be in the opposite relationship or both may be moved.
The lower mold 13 contains a movable punch 14 (inner guide member) and a spring material 15. The movable punch 14 is always supported upward by the spring material 15, and its upper end is kept protruding from the lower mold 13 by a predetermined length. The lower end of the movable punch 14 is housed in the lower mold 13 together with the spring material 15. When the upper die 12 descends, the movable punch 14 moves downward while pushing the spring material 15. When the upper die 12 rises, the movable punch 14 returns to its original position due to the repulsive force of the spring material 15.

The upper mold 12 is provided with a relief portion 16 (cavity) according to the shape of the sealing portion 5. The relief portion 16 has a concave (concave shape) pressure surface that is slightly larger in size than the sealing portion 5 and is recessed in an oval shape. The relief portion 16 is arranged so as to come on the axis of the movable punch 14.

A pair of guide plates 17 and 17 (outer guide members) that can move in the horizontal direction are provided between the upper mold 12 and the lower mold 13. The guide plates 17 and 17 are arranged so that the C-shaped or U-shaped plates face each other when viewed from the plane direction (upper in FIG. 5). The inwardly facing ends of the guide plates 17 and 17 are inclined surfaces on which the intermediate wall 5B of the sealing portion 5 can be formed.

When the sealed portion 5 of the simply sealed blister container 10 is set on the movable punch 14, the guide plates 17 and 17 subsequently move inward to the left and right and are held at a position surrounding the sealed portion 5 in an annular shape. (See FIG. 6). In this state, when the upper die 12 is lowered and the movable punch 14 is pushed downward, the movable punch 14 is stopped at the position where it hits the guide plate 17 (bottom dead center) (see FIG. 7). At this time, a gap is formed between the movable punch 14, the relief portion 16 of the upper die 12, and each pressure surface of the guide plate 17, and the sealing portion 5 is formed in the gap.

Next, a method of sealing the blister container 10 of the present embodiment will be described.
When the blister container 10 is sealed, as described above, the article M is stored between the upper container 2 and the lower container 3, and the protruding portions of both are fitted to each other to form the sealing portion 5 (simple sealing). In addition to such a primary step, as a secondary step, the sheet wall of the sealing portion 5 is press-molded into a mushroom-shaped cross section by the sealing device 11.

When using the sealing device 11, first, the simply sealed blister container 10 is positioned on the lower mold 13. Positioning of the blister container 10 is performed by fitting the sealing portion 5 of the container to the tip of the movable punch 14 of the lower mold 13. In the present embodiment, the movable punch 14 is fitted in the hollow space of the lower protrusion 3c of the lower container 3 so as to be movable in the height direction along the inner wall of the sheet.
Regarding the procedure for positioning the blister container 10, the lower container 3 (lower protrusion 3c) is fitted to the tip of the movable punch 14 in advance before the above-mentioned simple sealing, and then the lower container 3 (lower protrusion 3c) is fitted. ) May be fitted with the upper container 2 (upper protrusion 2c).

After positioning the blister container 10 on the lower mold 13 in this way, the guide plate 17 is operated and moved to the movable punch 14 side. When the guide plate 17 moves to the movable punch 14 side, as shown in FIG. 6, the guide plate 17 is placed on the flange portion of the blister container 10, and its inward facing end is the sheet outer wall of the sealing portion 5 (upper protruding portion 2c). Come to the position surrounding. Then, the guide plate 17 is maintained at a height lower than that of the sealing portion 5 (upper protruding portion 2c and lower protruding portion 3c).

When the upper die 12 is lowered in such a state, the upper die 12 presses the sealing portion 5 downward together with the movable punch 14 and stops at the position (bottom dead center) of the guide plate 17 (see FIG. 7). At this time, the portion of the sheet wall of the sealing portion 5 that exceeds the height of the guide plate 17 is compressed into a wide shape by the relief portion 16 of the upper mold 12, and there are two portions that do not exceed the height of the guide plate 17. It stays in the gap between the guide plate 17 and the movable punch 14. As a result, the sealed portion 5 is formed into a mushroom-shaped cross section.
Since the press-molded sealing portion 5 has a double sheet wall having a mushroom-shaped cross section, this serves as a stopper and does not easily come off.

After that, when the upper mold 12 and the guide plate 17 are returned to the original positions, the movable punch 14 is raised by the spring material 15, and the blister container 10 after sealing is slightly lifted from the lower mold 13. The sealing work is completed by removing the blister container 10 from the lower mold 13.
When sealing another blister container 10, the simply sealed blister container 10 is set in the sealing device 11 in order, and the sealed portion 5 is press-molded by the same procedure.

When the article M is taken out from the blister container 10 sealed by press molding, the blister container 10 is opened by grasping both the tabs of the upper container 2 and the lower container 3 and pulling them apart with an appropriate force. At this time, the double sheet wall of the sealing portion 5 is plastically deformed and broken, so that a trace of opening of the blister container 10 remains.

As described above, according to the sealing method of the blister container 10 of the present embodiment, the primary step of fitting both the protruding portions of the upper container 2 and the lower container 3 and the secondary step of preventing tampering are continuously and instantaneously performed. This can reduce the labor and time required for sealing work.
Further, since a packaging material such as a tape or a seal is not used for sealing the upper container 2 and the lower container 3, it is possible to suppress the generation of dust at the time of opening.

Further, according to the sealing structure of the blister container 10, in addition to the effect of the above-mentioned sealing method, the sheet wall of the sealing portion 5 is broken or crushed due to plastic deformation when the blister container 10 is opened. You can definitely leave it. As a result, the tamper-proof effect can be improved and the reliability of packaging by the blister container 10 can be enhanced.

Further, according to the sealing structure of the blister container 10, the tapered intermediate wall 5B (leg portion) connected to the double sheet wall having a mushroom-shaped cross section of the sealing portion 5 in the upper container 2 and the lower container 3 (leg portion). Since it is provided with a subordinate portion), a shearing force is likely to be generated in this intermediate wall 5B. As a result, the sealing portion 5 (upper protruding portion 2c and lower protruding portion 3c) of the upper container 2 and the lower container 3 can be peeled off relatively easily, and the workability at the time of opening can be improved.

[Second Embodiment]
The blister container 20 of the second embodiment is shown in FIGS. 8 and 9. The blister container 20 of the second embodiment is a double sheet wall having a mushroom-shaped cross section formed by a sealed portion 5 having a flat shape. The sealed portion 5 does not have a tapered inclined surface like the intermediate wall 5B of the first embodiment.
As shown in FIG. 8, in the blister container 20, a sealed portion 5 in which the protruding portions 2c and 3c of both are fitted to the flange portions of the upper container 2 and the lower container 3 is formed. As shown in FIG. 8B, the double sheet wall in the sealed portion 5 rises substantially perpendicularly from the root portion thereof to form a leg portion having a cross-sectional mushroom shape, and the lower wall 5A is substantially perpendicular to the lower wall 5A. It is provided with an intermediate wall 5B that bends to form an umbrella portion having a cross-section mushroom shape, and an upper wall 5C that is connected to the intermediate wall 5B to form an umbrella portion having a cross-section mushroom shape. That is, the intermediate wall 5B of the sealing portion 5 is not formed with a tapered inclined surface that expands upward.

According to the configuration of the second embodiment, in addition to the effect of the first embodiment, when the sealing portion 5 of the blister container 20 is separated, the shearing force is less likely to act on the double sheet wall. As a result, it is possible to realize a blister container 20 having a strong sealing performance in which the article M after packaging cannot be easily taken out.
The sealing device 11 for molding the sealing portion 5 of the blister container 20 in this way may basically adopt the same configuration as that of the first embodiment. For example, as shown in FIG. 9, the movable punch 14 of the lower die 13, the relief portion 16 of the upper die 12, and the pressure planes of the guide plate 17 are made horizontal or vertical so that the sealing portion 5 having no tapered inclination is formed. Can be molded.

[Third Embodiment]
The blister container 30 of the third embodiment is shown in FIGS. 10 and 11. In the first and second embodiments, the blister container is provided with the spot-like sealing portion 5, but in the third embodiment, the sealing portion 5 connected in a ring shape when viewed from the plane direction is adopted.
As shown in FIG. 10, the blister container 30 has hollow protrusions 2c and 3c which are connected to the upper container 2 and the lower container 3 in a circular shape in a rectangular shape. The upper protruding portion 2c is integrally formed with the upper flange portion 2b so as to surround the upper accommodating portion 2a of the upper container 2. The lower protruding portion 3c is integrally formed with the lower flange portion 3b so as to surround the lower accommodating portion 3a of the lower container 3. When the lower container 3 and the upper container 2 are bent and overlapped with each other via the hinge 4, the upper protruding portion 2c and the lower protruding portion 3c are fitted together to form an annular sealed portion 5 (see FIG. 11).

When the blister container 30 of the third embodiment is sealed, as shown in FIG. 11A, both the protruding portions 2c and 3c of the upper container 2 and the lower container 3 are fitted in an annular shape and simply sealed. Subsequently, as shown in FIG. 11B, the annular sealing portion 5 is press-molded to form the double sheet wall into a mushroom-shaped cross section. As a result, the upper container 2 and the lower container 3 are sealed in a ring shape to prevent falsification.
As for the sealing device 11 for press-molding the annular sealing portion 5, basically the same configuration as that of the first embodiment may be adopted. For example, it is sufficient to arrange the upper die 12, the movable punch 14, the guide plate 17, and the like in an annular shape in accordance with the annular sealing portion 5.

According to the configuration of the third embodiment, in addition to the effect of the first embodiment, the sealing effect of the upper container 2 and the lower container 3 can be enhanced by the annular sealing portion 5. Since there is almost no gap between the upper container 2 and the lower container 3 after sealing, it is possible to prevent fraudulent acts such as inserting foreign matter through the gap between the two containers.

[Fourth Embodiment]
The blister container 40 of the fourth embodiment is shown in FIGS. 12 and 13. In the fourth embodiment, the sealed portion 5 of the blister container 40 has a flat cross-sectional mushroom shape. In the fourth embodiment, when the sealing portion 5 is press-formed, only the movable punch (inner guide member) is used, and the guide plate (outer guide member) is not used.

As shown in FIG. 12, in the blister container 40, a sealing portion 5 in which the protruding portions 2c and 3c of both are fitted to the flange portions of the upper container 2 and the lower container 3 is formed. As shown in FIG. 12B, the double sheet wall in the sealed portion 5 has a cross section of a lower wall 5A that rises from the root thereof to form a mushroom-shaped leg portion and a cross section that is bent at a substantially right angle from the lower wall 5A. It is provided with an intermediate wall 5B that forms a mushroom-shaped subordinate portion, and an upper wall 5C that is connected to the intermediate wall 5B and forms a mushroom-shaped subordinate portion. These seat walls are folded twice at approximately 180 ° and are in close contact with each other and overlap each other.

As shown in FIG. 13, the sealing device 41 for press-molding the sealing portion 5 of the blister container 40 has a configuration in which the guide plate 17 is omitted from the sealing device of the second embodiment described above.
The sealing device 41 includes an upper mold 12 and a lower mold 13 for upward molding, and the lower mold 13 is provided with a movable punch 14 (inner guide member) and a spring material 15. The upper mold 12 is provided with a relief portion 16 (cavity) that matches the shape of the sealing portion 5. The relief portion 16 has a concave (concave shape) pressure surface having a size slightly larger than that of the sealing portion 5. The relief portion 16 is arranged so as to come on the upper axis of the movable punch 14.
The depth of the concave machined surface in the relief portion 16 is set to be approximately four times the thickness of the single sheet of the blister container 40.

When the blister container 40 is sealed, the article M is stored between the upper container 2 and the lower container 3, and the protruding portions 2c and 3c of both are fitted to form the sealing portion 5 (simple sealing). In addition to such a primary step, as a secondary step, the sealing portion 5 is press-molded into a flat cross-sectional mushroom shape by the sealing device 41.

As a procedure for press molding by the sealing device 41, first, the simply sealed blister container 40 is positioned on the lower mold 13. This positioning method is the same as that of the first embodiment.
When the upper mold 12 is lowered with the blister container 40 positioned on the lower mold 13, the sealing portion 5 is pressed downward together with the movable punch 14, and the upper mold 12 is positioned on the seat surface of the upper container 2 (bottom dead center). Stop at (see FIG. 13). At this time, a gap is created between the movable punch 14 and each pressure surface of the relief portion 16 of the upper die 12, and the tip portion of the sealing portion 5 fits in the gap and is compressed. As a result, the portion of the sheet wall of the sealing portion 5 that exceeds the sheet thickness around the sealing portion 5 in which the upper container 2 and the lower container 3 are overlapped is formed wider than the portion that does not exceed the sheet thickness.
The press-molded sealing part becomes a double-seat wall with a flat cross-section mushroom shape, which prevents it from coming off and does not easily come off.

According to the configuration of the fourth embodiment, as in the first embodiment, the primary step of fitting both the protruding portions of the upper container 2 and the lower container 3 and the secondary step for preventing tampering are continuously and instantaneously performed. It can be carried out, and the labor and time of the sealing work can be reduced. In the fourth embodiment, since the sealing portion 5 is press-molded without using the guide plate 17, the configuration of the sealing device 41 can be simplified and the sealing work time can be further shortened.
Further, since a packaging material such as a tape or a seal is not used for sealing the upper container 2 and the lower container 3, it is possible to suppress the generation of dust at the time of opening.

Further, according to the sealing structure of the blister container 40, when the blister container 40 is opened, the sheet wall of the sealing portion 5 is broken or crushed due to plastic deformation, so that a trace of the opening can be surely left. As a result, the tamper-proof effect can be improved and the reliability of packaging by the blister container 10 can be enhanced.
Further, since the protruding shape of the sealing portion 5 becomes smaller, the protruding portion becomes less noticeable on the appearance of the container, and the sheet material can be saved. In addition, by lowering the height of the sealing portion 5, the plate thickness is reduced (especially rising from the root) when the upper protruding portion 2c and the lower protruding portion 3c are drawn (vacuum forming or pneumatic forming) in the blister container 40. The portion) can be further suppressed, and the thickness of the double sheet wall of the sealing portion 5 can be finished more uniformly.

[Fifth Embodiment]
The blister container 50 of the fifth embodiment is shown in FIGS. 14 and 15. In the fifth embodiment, the sealing portions 5, 5 and 6 are provided at a plurality of locations of the blister container 50 (see FIG. 15), and among these, only some of the sealing portions 5, 5 are press-molded to prevent tampering. It is a thing.

As shown in FIG. 14, in the blister container 50, the sheet-shaped upper container 2 and the lower container 3 are connected in a plane direction. The upper container 2 and the lower container 3 have a substantially vertically symmetrical relationship with the hinge 4 interposed therebetween.
The upper container 2 includes an upper accommodating portion 2a having a rectangular flat cross section and a U-shaped cross section, and an upper flange portion 2b connected to the outer periphery thereof. A home-based upper protrusion 2e is formed on the upper tab 2d side of the upper flange portion 2b when viewed from the plane direction, and flat circular upper protrusions 2c and 2c are formed on both sides thereof.
The lower container 3 includes a lower accommodating portion 3a having a rectangular flat cross section and a U-shaped cross section, and a lower flange portion 3b connected to the outer periphery thereof. A heart-shaped lower protrusion 3e is formed on the lower tab 3d side of the lower flange portion 3b when viewed from the plane direction, and flat circular lower protrusions 3c and 3c are formed on both sides thereof.

[Modification example]
Although the blister container according to the first to seventh embodiments has been described, the embodiment of the present invention is not limited to these, and may be accompanied by various modifications.
For example, in the first to fifth embodiments, one of the upper container 2 and the lower container 3 may be omitted to form a flat plate. In this case, the flat container acts as a lid for the other container.
The shape of the sealing portion 5 is not limited to the above-described embodiment, and a rectangular shape, an elliptical shape, a rhombus shape, a ribbon shape, a polygonal shape, or the like may be adopted when viewed from the plane direction. Further, in the above-mentioned third embodiment, the sealing portion 5 is formed into a rectangular annular shape when viewed from the plane direction, but it is also possible to make this a linear shape or a curved line shape.

Further, as shown in FIG. 22, a sealing portion protruding downward may be added to the tip portion of the sealing portion 5 (modification example 1).
For the downward sealing portions 7 and 7 shown in FIG. 22 (A), the downward protruding portions provided in advance in the upper container 2 and the lower container 3 are fitted together, or the tip sheet wall of the sealing portion 5 is pushed downward during press molding. It is possible to form with. The downward sealing portions 8 and 8 shown in FIG. 22B can be formed by arranging a downward movable punch on the upper side of the sealing portion 5 and arranging a guide plate on the lower side during press molding.
The configuration of the modified example shown in FIG. 22 can be applied to the annular sealing portion as in the third embodiment to further improve the airtightness of the blister container. Such a blister container is effective when used for packaging gel-like products and the like.

Further, in the first to seventh embodiments, a thin wall S serving as a cut portion of the sheet wall may be adopted in the vicinity of the base of the protruding portion as in the protruding portion 3f shown in FIG. 23 (modification example 2).
The thin wall S is continuous along the peripheral surface near the root of the protruding portion 3f, and the thickness of the sheet wall is smaller than that of the other portions. The thickness of the thin wall S is set so that the sheet wall is broken by an appropriate load (pulling force) when the blister container is opened, as will be described later.

In the example of FIG. 23A, a thin wall S is provided on the seat wall of the protruding portion 3f via a step. When the thickness of the original sheet is X0, the thickness of the thin wall S is X1, the molding protrusion drawing depth Y0, and the molding drawing depth Y1, X0> X1 and Y0> Y1 are formed.
In the example of FIG. 23B, the thickness of the sheet wall of the protruding portion 3f is formed so as to gradually become smaller and smaller from the tip side to the root side. The thickness of the base of the protruding portion 3f is the smallest, and in this example, it is 1/2 or less of the original sheet.

As a method for forming such a thin wall S on the protruding portion 3f, for example, a dedicated mold for drawing (vacuum forming or compressed air forming) a sheet-shaped resin can be used. Since the thin wall S of FIG. 23 (B) has no step on the sheet wall, it can be molded with a mold having a simpler structure than the thin wall S of FIG. 23 (A).

When sealing the blister container according to the second modification, for example, the procedure is the same as that of the sixth embodiment described above.
First, as shown in FIG. 24 (A), the protruding portion 3f of the lower container 3 is fitted into the through hole 2f of the upper container 2 to form the sealing portion 5 (simple sealing). When the sealing portion 5 is press-molded, as shown in FIG. 24B, the sealing portion 5 becomes a sheet wall having a flat cross-section mushroom shape, and the thin wall S near the root thereof is along the inner circumference of the through hole 2f. Come to the position.
When opening the blister container, when the through hole 2f and the protruding portion 3f are separated from each other, the sheet wall of the lower container 3 having a mushroom-shaped cross section is pulled up and down and broken along the thin wall S (see FIG. 24 (C)). ).
By adopting the thin wall S for the sheet wall of the sealing portion 5 in this way, the opening work of the blister container can be simplified. The manufacturing process can be simplified by omitting the cut line L of the sixth embodiment.

The thin wall S according to the second modification can also be applied to the sealing portion 5 of the double sheet wall as in the first to fifth embodiments. In this case, as shown in FIG. 25, a thin wall S is provided on the inner (male side) lower protruding portion 3c of the upper protruding portion 2c and the lower protruding portion 3c forming the sealed portion 5.
When sealing the blister container, as shown in FIG. 25 (A), first, the lower protruding portion 3c is fitted inside the upper protruding portion 2c to form the sealed portion 5 (simple sealing). When the sealed portion 5 is press-molded, as shown in FIG. 25 (B), the sealed portion 5 becomes a double sheet wall having a mushroom-shaped cross section, and the vicinity of the root of the inner sheet wall becomes a thin wall S.
When opening the blister container, if the upper protruding portion 2c and the lower protruding portion 3c are separated from each other, the inner sheet wall of the double sheet wall having a mushroom-shaped cross section is pulled up and down and broken along the thin wall S ( See FIG. 25 (C).
As described above, even when the thin wall S is adopted for the sealing portion 5 of the first to fifth embodiments, the opening work of the blister container can be simplified.
