Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blister package in which articles to be packaged such as medicines and foods are compactly housed in fixed units and can be easily separated from each unit package.

[0002]

BACKGROUND OF THE INVENTION In a blister package, generally, a certain number of recesses formed in a synthetic resin molding sheet are used to accommodate a certain unit of an object to be packaged, and then a sealing sheet such as an aluminum foil is attached to the molding sheet to form each recess. The opening is sealed, and a cutoff line is formed between the concave portions so that the unit packaging can be separated. In addition, individual items to be packaged are separated into fixed units and individually packaged, and because they are compact, have excellent portability, and they have the advantages of being attractive and easy to take out when in use, such as pharmaceuticals, food, and miscellaneous goods. Widely used for packaging.

Particularly, in the case of pharmaceuticals, solid formulations such as tablets and capsules have a high degree of application, and most of the medical pharmaceuticals are occupied in this blister packaging today. This has the advantage that the patient taking the medicine can easily take out the medicine from the package, and can be divided into single-dose units, which is excellent in portability, and is compact for the doctor or pharmacist who administers the medicine. Since a certain number of unit packagings are formed on one sheet, storage and counting management are easy, and there are advantages such as the molded sheet is transparent and the identification of the packaged item is excellent. This is because it has many advantages such as high-speed automation, excellent quality assurance such as moistureproof function, and cost reduction in compact packaging.

The above-mentioned blister packaging is generally made of PVC, PE or P because of the necessity of retaining the shape of the concave portion of the molded sheet.
Hard materials such as P, PET, and aluminum are used.
Therefore, when the blister package is separated into unit packages, the corners are in a squared state. However, since each unit packaging of the blister packaging is formed compactly, the blister packaging separated into each unit packaging may be accidentally swallowed together with the blister packaging without taking out the article to be packaged from the blister packaging. . This accidental ingestion is particularly likely to occur when the patient is separated into individual dosage units and given to the patient. And this swallowed blister package is apt to catch the angled corners of the digestive tract such as the esophagus and the gastrointestinal tract, and to damage the inner wall of the digestive tract, which requires surgical treatment as esophageal foreign body disease. However, the frequency of occurrence is increasing, and many cases have been reported.

In order to solve this problem, it is possible to use a material that dissolves or disintegrates in the digestive tract or a flexible material as the material for the blister packaging. However, when a material that dissolves or disintegrates in the digestive tract, such as PVA, PVP, gelatin, a cellulosic polymer, a starch-based material, or a protein, is used, the moisture-proof function of the material is inferior. Not suitable for. Further, with a soft material, it is not possible to retain the shape of the concave portion formed in the molded sheet, and the characteristics of blister packaging cannot be exhibited in the form of conventional strip packaging.

[0006]

2. Description of the Related Art Conventionally, there is a blister package configured as follows in order to prevent accidents due to accidental ingestion. As shown in FIGS. 7 to 9, the prior art 1 omits all or part of the cutoff line to be formed between the plurality of recesses. That is, as shown in FIG. 7, the recesses (53) are arranged in two rows 5
All the recesses (5
The cutting line between 3) is omitted, and in the modification shown in FIG. 8, only the vertical cutting line (54) is formed in the blister package (51) of the same kind, and all the horizontal cutting lines are omitted. Also,
Another modification shown in FIG. 9 is a blister package (51) in which the recesses (53) are arranged in three columns and four rows, in which only the horizontal cut lines (54) are formed and all the vertical cut lines are omitted. In this prior art 1, since the entire blister package (51) or the separated plural unit package (55) is formed in a large size, there is no risk of accidental ingestion.

The prior art 2 is, for example, as shown in FIG. 10, a blister package (5
In 1), the vertical and horizontal cutoff lines (54) are formed between the recesses (53), and the unit packaging (56) having the recesses (53) is formed so as to be separable, and the outer peripheral edge of the blister package (51) is formed. At (52), a wedge-shaped recess (57) is formed at the end of the cutoff line (54). As a result, when the unit packaging (56) is separated, of the four corners of each unit packaging (56), the outer peripheral edge (5
The part located in 2) is formed in a smooth rounded corner and is not angular.

Prior art 3 is, for example, Japanese Utility Model Publication No. 46-1.
As described in Japanese Patent No. 3503 (see FIG. 11), in addition to the contents of the above-mentioned conventional technique 2, each intersection (5
8) is punched out into a substantially rhombic shape, and a space portion (59) is formed in this portion. As a result, when the blister pack (51) is separated into the unit packs (56), all the corners become smooth, and the blister pack does not stay in the esophagus or the gastrointestinal tract even if accidentally swallowed. There is no fear of causing illness.

[0009]

However, the above-mentioned prior arts 1 to 3 have the following problems. Generally, it is indispensable that a medicinal drug can be separately administered in each unit package, and inpatients often receive the drug separately in a dosage unit for each administration time. Blister packaging without the cut-off line 1 is not applicable. In addition, since this blister package is easily divided by the patient with scissors or the like for each unit package, there is still a risk of accidental ingestion, and since each divided unit package has square corners, The above accident cannot be completely prevented.

In the above-mentioned prior art 2, in the blister package in which the recesses are arranged in a plurality of columns and a plurality of rows, when each unit package is separated, only some of the four corners are rounded. I can't. That is, the corners located at the intersections of the vertical and horizontal cutoff lines are angular, and as a result, the blister package may remain in the esophagus or the gastrointestinal tract if swallowed.

In the above-mentioned conventional technique 3, since all the corners of each separated unit package are smooth, there is no possibility of causing esophageal foreign body disease even if accidentally swallowed. However, in this Prior Art 3, since each crossing portion of the vertical and horizontal cutoff lines of the blister package is punched out into a substantially rhombic shape, there is a problem that a large number of punched chips are generated in the manufacturing process. That is,
When these punching scraps are mixed in the product, the commercial value is lowered, and also in each manufacturing facility, when the punching scraps enter the facility, it is likely to cause a trouble. Therefore,
It is necessary to completely remove these punch chips in the manufacturing process, but it is not easy to remove these punch chips.
The number of production processes will increase or the manufacturing equipment will need to be modified. Further, since the molded sheet itself is punched out, the blister package is likely to be bent or curled, which causes a problem in the stability of the production process.

The present invention solves the above problems and utilizes the characteristics of blister packaging, but when the individual packaging is separated, the four corners are not square, and no punching scraps are produced during the manufacturing process. It is an object of the present invention to provide a blister package that can be manufactured by a manufacturing facility or manufacturing process.

[0013]

In order to achieve the above object, the present invention is characterized by having the following configuration, for example, as shown in FIGS. That is, molded sheet
Forming a large number of concave portions (3) in (2) in a plurality of columns and a plurality of rows,
After accommodating the article to be packaged (4) in each recess (3), the seal sheet (5) is attached to the molding sheet (2) to form each recess (3).
The opening (6) is sealed, and vertical and horizontal cutoff lines are provided between the recesses (3 ...).
Unit packaging forming (7) and having recesses (3) respectively
(8) is formed so as to be separable, and a wedge-shaped recess (10) is formed at the end of the cut line (7) by the outer peripheral edges (9) of the molding sheet (2) and the seal sheet (5), A rhombus cutoff line (12) connecting the vertical cutoff line (7) and the horizontal cutoff line (7) is formed at each intersection (11) of the vertical and horizontal cutoff lines (7, 7) and is surrounded by the rhombus cutoff line (12). It is characterized in that the substantially rhombic cut-off portion (13) is detachably connected to each of the unit packages (8) adjacent to the periphery by a rhombus cut-off line (12).

Here, as the molded sheet, PVC, P
A single material or composite material of plastic such as P, PE, PET, PS or a composite material with aluminum foil is used.
As the seal sheet, aluminum foil, paper, plastic film or the like is used. Further, the rhombus cutoff line may be one that connects the vertical cutoff line and the horizontal cutoff line, and may be a straight cutoff line, but if it is formed into a smooth curve, the corner of the separated unit package It is more desirable because the part becomes smooth.

[0015]

[Function] Since vertical and horizontal cutoff lines are formed between the respective recesses,
By tearing and separating at the cutting line, each unit package is separated as necessary. Each individually separated unit package forms a wedge-shaped recess at the end of the cut line at the outer peripheral edge of the blister package, and forms a rhombus cut line that connects the vertical cut line and the horizontal cut line at each intersection of the vertical and horizontal cut lines. Because it is done, all you need to do is to cut off the roughly rhombus-shaped cut-off part, and all four corners will have roundness, and it will not be square.

Moreover, since the separating portion is connected to each unit package adjacent to the periphery by a diamond-shaped cutting line, the separating portion can be separated.
No punch scraps are produced in the manufacturing process.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show Embodiment 1 of the present invention, FIG. 1 is a partially cutaway plan view of a blister package, and FIG. 2 is a plan view in a state of being cut into individual unit packages.

As shown in FIG. 1, this blister package
(1) is applied to the PP molded sheet (2) with a thickness of 300 μm.
Individual recesses (3) are formed in 2 rows and 5 lines, and each recess is formed.
After accommodating the tablets (4) to be packaged in (3), the molding sheet (2) is pasted with the seal sheet (5) to form the recesses.
The opening (6) of (3) is sealed. In addition, this seal sheet is obtained by coating an aluminum foil having a thickness of 20 μm with a 2 μm overcoat on the lower surface and a 4 μm seal coat on the upper surface.

Perforation lines (7) are formed between the respective recesses (3 ...) As vertical and horizontal cutoff lines, and the unit package (8) having the respective recesses (3) has the vertical and horizontal perforation lines (7). It is configured so that it can be separated.

The molded sheet (2) and the seal sheet (5), which are attached to each other, have a wedge-shaped recess (10) formed at the outer peripheral edge (9) at the end of the perforation line (7). , Vertical perforation line (7) at each intersection (11) of vertical and horizontal perforation lines (7, 7)
A curved rhombic perforation line (12) that smoothly connects the horizontal perforation line (7) is formed. This rhombus perforation (1
The substantially rhombus-shaped cut-off portion (13) surrounded by 2) is connected to each unit package (8) adjacent to the periphery, and the rhombus perforation line (1
It is constructed so that it can be separated from each unit package (8) in 2). In addition, it is desirable to shorten the interval between the cuts of the vertical and horizontal perforation lines and the diamond-shaped perforation line in order to facilitate the separation, and it is formed to be 0.1 to 0.3 mm.

When the vertical and horizontal perforation lines (7) and diamond-shaped perforation lines (12) are separated, as shown in FIG.
Separated into (8), each unit packaging (8) has rounded corners and is not square. As a result, even if it is accidentally ingested as it is, there is no possibility of staying in the digestive tract.

3 and 4 show a second embodiment of the present invention,
FIG. 3 is a partially cutaway plan view of the main part of the blister package, and FIG. 4 is an enlarged cutaway perspective view of the main part.

The second embodiment is a blister package (1) made of the same material as the above-mentioned first embodiment, and a vertical perforation line (7) is provided at each intersection (11) of the vertical and horizontal perforation lines (7). A continuous linear rhombic slit (12) for connecting the horizontal perforation line (7) is formed only on the molding sheet (2).

The depth of the rhombic slit (12) may be 20 to 80% of the thickness of the molded sheet (2), but the cut portion (13) surrounded by the rhombic slit (12) is a unit package ( It is desirable to form deeper so that it can be easily separated from 8). That is, in Example 2, as shown in FIG. 4, the diamond-shaped slits (12) were formed over the entire thickness of the molded sheet (2). However, it is not formed on the seal sheet (5). In this case, the intersecting part (13) should not come off from the blister package (1) during the manufacturing process.
Also in this case, it is necessary to surely bond the molded sheet (2) and the seal sheet (5).

When the rhombus cutoff line (12) is formed by continuous slits as in the second embodiment, the cutting line forming blade has a simpler structure than the rhombus perforation line of the first embodiment, and the cost is low. Can be carried out.

In the second embodiment, all the rhombus cutoff lines (12) are formed by continuous slits, but as in the modification shown in FIG. 5, some rhombus cutoff lines (12a) are formed by perforation lines. It is also possible to do so.

FIG. 6 is a partially cutaway plan view showing the third embodiment. In this Example 3, a molded sheet (2) made of PVC having a thickness of 200 μm is used, and a vertical and horizontal cutoff line (7) and a rhombus provided at each intersection (11) of the vertical and horizontal cutoff line (7). Each of the cut lines (12) is formed by continuous slits formed only on the molded sheet (2). Other configurations are the same as those in the first embodiment.
Is the same as.

In each of the above-mentioned embodiments, the case of packaging tablets has been described, but the blister packaging of the present invention can be applied to objects to be packaged other than capsules and pharmaceuticals, and the recesses formed in the molded sheet can be used. It goes without saying that the number is not limited to that in the above-mentioned embodiment.

[0029]

Since the present invention is constructed and operates as described above, it has the following effects. (B) Individually separated unit packaging has a rounded shape at all four corners and is not angular, only by cutting the roughly diamond-shaped cuts. It is safe because there is no risk of causing esophageal foreign body disease or the like that does not stay in the body and requires surgical treatment.

(B) Since the cut-off portion is connected to each unit package adjacent to the periphery by a diamond-shaped cut-off line, the cut-off portion does not generate punching scraps or the like in the manufacturing process. Therefore,
There is no risk that these scraps will be mixed and the commercial value of the product will be reduced, and the processing for removing the punching scraps required in the prior art 3 is not required. As a result, there is no need to modify the manufacturing equipment or change the production process, the existing equipment and materials can be applied as they are by simply changing the blade die for forming the cutoff line, and the cost can be kept low.

(C) Since the blister packaging can be separated into individual packaging units, the hospitals and pharmacies can perform counting management, storage, medication, etc. as they are, and the individual blister packaging has all four corners. Since it is not stretched, there is no risk of injuring fingers when handling these unit packages, and it is safe.
