[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blister package which allows easy removal of stored solids by a simple operation.

[0002]

[Background of the Invention] A blister package in which a molded sheet is provided with a concave molded part, and a solid material is stored in the molded part one by one and sealed with a sealing material is used for pharmaceuticals, cosmetics, food, industrial products,
Or it is widely used for general goods. In particular, pharmaceuticals are referred to as PTPs (press-through packs), and occupy most of the packaging of pharmaceuticals. It is 1
Because each product is packaged, it is compact and easy to handle, easy to count and control, easy to automate the production process, high in productivity, easy to moisture-proof and easy to assure quality. Things.

[0003] However, these advantages are often considered to be advantages from the producer's point of view, and are not yet fully satisfactory from the point of view of users such as sick people and patients. In particular, in recent years, where the frequency of drug therapy is high, there is much room for improvement in the complexity of taking out the stored solid matter from the blister package at the time of ingestion because many tablets are taken at one time.

[0004]

2. Description of the Related Art In general, methods for removing solids from a blister package are roughly classified into a method using extrusion (press-through) in the case of PTP shown in FIG. 9 and a method using peeling (peeling) shown in FIG.

[0005] The press-through method, as shown in FIG.
A method of pressing the molded part (2) with a finger to transmit the pressing force to the stored solids (B) such as tablets, and to break the sealing material (6) by the pressing force to take out the solids (B) It is applied to most medicines such as tablets and capsules.

On the other hand, in the peeling method, as shown in FIG. 10, the sealing material (6) is peeled off from the adhesive surface of the molded sheet (1) with a fingertip and opened, and the stored solid (B) is removed. It is a method of taking out and is often used for industrial products and general miscellaneous goods. This peeling method is more troublesome to take out than the previous press-through method, and is not often used in pharmaceuticals. However, even in the case of pharmaceutical products, this peel method can be used as it is or in combination with the press-through method as a safety package (Safety Package) to prevent infants from accidentally taking out and ingesting dangerous drugs when packaging them. May be done.

[0007]

The above-mentioned conventional blister packaging has many advantages from the producer's point of view, but has the following problems from the user's side. 1. Extraction operation is not easy. The work of removing small solids stored in small blister packages is an extremely fine work of the fingertips, and requires considerable dexterity at the fingertips. In addition, even in the case of the press-through method, the removal operation is not easy. In addition, in the case of the peeling method, cardboard is often used as a sealing material, and in order to enhance moisture resistance, only the surface to be bonded to the molded sheet is often subjected to resin processing or the like. For this reason,
If a force is applied to peel off the sealing material, the cardboard that is weaker than the adhesive strength will be damaged easily, leaving only the resin-processed surface adhered to the molded sheet. Is extremely difficult.

[0008] 2. It is easy to drop solids during the unloading operation. In the press-through method, depending on how the user puts his / her finger, the stored solid matter easily jumps out in an unexpected direction due to the pressing force for opening, and often fails to catch the solid matter and falls on the floor or the ground. As a result, there is a problem that a solid substance such as a tablet becomes dirty and unusable or lost. In the case of the peeling method, the molded sheet held in an unstable position is easily vibrated by the force of peeling off the sealing material, and since the entire opening is opened, solids can be easily removed from the wide opening. And fall down, as in the press-through method.

[0009] 3. The preparation for taking the drug is troublesome because it is not packaged once. Today, it is customary to take a large number of medicines taken at the hospital at the same time.However, conventional blister packs are usually packaged one by one, so patients can take multiple medicines from the hospital. Must be taken separately and taken as a single dose each time it is taken. For this reason, one tablet must be repeatedly taken out of the molded part made of plastic many times, which is extremely complicated. Particularly for elderly people, it is not easy to repeat detailed work many times, and this is a major problem when taking the medicine.

[0010] 4. The tablet may be broken by the press-through method. In general, if the strength of a tablet is increased during manufacture, the dissolution in the digestive tract at the time of ingestion is slowed, so that it cannot be increased beyond a certain limit. Moreover, this strength decreases as the tablet absorbs moisture. For this reason, the strength of the stored tablet may be lower than the strength of the sealing material, and the press-through method of applying a pressing force to the tablet at the time of opening has a disadvantage that the tablet is broken before opening. When the tablet is broken, it becomes difficult to take the tablet, and there is a problem that the powder and the fragments are lost and the dose is reduced.

5. The broken seal material is released. Hard aluminum foil, which is easy to open, is often used as a sealant for blister packaging of pharmaceuticals, but when the tablet is taken out, this aluminum foil also breaks at the same time and becomes a piece, which can be swallowed with the tablet. There is.

6. May be accidentally swallowed in blister packaging. In some cases, blister packages containing tablets are cut off one by one and are prepared for taking.In this case, the blister packages are taken as they are without taking out the tablets and clogged in the esophagus or trachea, and surgical treatment is performed. There is a risk of developing the necessary so-called esophageal foreign body disease.

The present invention solves the above-mentioned problems, and provides a safe blister package which can easily take out stored solid matter by simple operation without damaging it, and can store a dose to be taken or used at one time. The purpose is to do.

[0014]

According to the present invention, in order to achieve the above-mentioned object, an opening edge of one of two openings divided by a virtual straight line crossing the opening of the molding portion. A peripheral notch is formed at a position outwardly separated from the opening so as to penetrate the molded sheet so as to surround the opening, and a straight line is linearly formed from both ends of the peripheral notch to the outer edge of the molded sheet along the virtual straight line. A notch is provided, and by bending the molded sheet around this straight cut, the sealing portion between the peripheral notch and the molded portion is forcibly peeled off to partially open the opening. It is characterized by having comprised in.

[0015]

In the present invention, since the straight cut is provided along an imaginary straight line that crosses the concave molded portion, the molded sheet is bent around the straight cut,
The concave molded portion of the molded sheet retains its shape and does not bend, and the flat portion outside the molded portion tends to bend together with the sealing material. As a result, the sealing portion between the molded portion and the peripheral cut is forcibly peeled off, and the portion of the opening of the molded portion between the virtual straight line and the peripheral cut is opened. The stored solids are sequentially taken out from the opened portion.

[0016]

A concave portion is formed in the center of the molded portion (2) formed in a horizontally long oval shape in a plan view, and three sugar-coated tablets (B) are accommodated therein. The molded sheet (1) is made of a hard material, and is made of plastic such as polyvinyl chloride, polyethylene, polypropylene, polyethylene terephthalate, polystyrene, polycarbonate, polyacrylonitrile, or a material such as aluminum. The molded sheet (1) is a thicker sheet than that of the press-through method so that the molded portion (2) is not deformed at the time of opening. For example, the thickness in the case of forming with polyvinyl chloride is 150 to 25 in the case of the press-through method.
Although those having a thickness of 0 μm are frequently used, the present invention employs 200 to 50 μm.
The thickness is preferably 0 μm, and in this embodiment, the thickness is 300 μm.

A sealing material (6) made of a composite material of polyester / aluminum foil / heat sealant is disposed on the above-mentioned molded sheet (1) so as to cover the opening (3) of the molded part (2). The sealing material (6) and the outer peripheral portion (5) of the opening (3) are bonded by thermal bonding. The material of the sealing material (6) is not limited to the configuration of the present embodiment, and any material may be used alone or in combination with a composite material as long as it can be bonded to the molded sheet. Also, the bonding method is not limited to the thermal bonding, and an appropriate bonding method such as a method using an adhesive can be used. However, the above-mentioned bonding is a great resistance to the opening operation if the bonding strength is too high,
It is desirable to set so that the adhesive strength is in the range of 300 to 2000 g / 15 mm width.

The one curved end portion (2a) of the molded portion (2) is located at a position separated from the peripheral edge (4) of the molded portion (2) by a width of about 2 mm. A peripheral cut (8) is provided along the opening (3) so as to partially surround the opening (3), and penetrates the molded sheet (1). A sealing portion (7) between the opening edge (4) and the peripheral cut (8) bonds the molded sheet (1) and the sealing material (6) to hermetically seal the inside of the molded portion (2). In particular, when the moisture-proof property is important, as in the blister package (A) of the present embodiment in which the medicine is stored, it is necessary to sufficiently adhere the adhesive. In addition, this sealing part
(7) is at least 1. in the case of heat bonding as in this embodiment.
Although a width of 5 mm or more is required, since the sealing portion (7) is opened by peeling off, the sealing portion (7) is desirably 5 mm or less so that it can be easily opened.

The above-mentioned peripheral cuts (8) are terminated at two intersections (9, 9) with a virtual straight line (11) traversing the molded part (2). Cut straight along the virtual straight line (11) to the outer edge (1a) of the molded sheet (1)
(10) is provided. The peripheral notch (8) may be provided along the opening edge (4) and up to a position intersecting the virtual straight line (11), and the shape is limited to a curved shape as in the present embodiment. is not. For example, when the opening periphery (4) is formed in a rectangular shape, and a virtual notch (8) is provided at a corner of the rectangle, assuming a virtual straight line (11) crossing two adjacent sides of the opening periphery (4). It may be formed in a bent straight line as shown in FIG. Further, in the present embodiment, the virtual straight line (11) is assumed to be orthogonal to the long axis of the oval shape of the molding part (2), but this virtual straight line (11) crosses the molding part (2). It may be in any direction such as a direction inclined with respect to the long axis.

In the molded sheet (1), the peripheral cuts (8)
On the side opposite to the molded part (2), a convex grip part (12) is formed. The grip portion (12) may have any structure that can easily hold one end of the blister package (A) when applying a force to bend the molded sheet (1) by the linear cut (10). Therefore, when it can be securely held only by the outer peripheral part (5) of the molded part (2), it is not necessary to form it, and even if it is formed, it is not limited to the shape of this embodiment.

Next, the procedure of the opening operation will be described.
Hold the molded part (2) side of the blister package (A) and the grip part (12) firmly, and seal around the virtual straight line (11).

[Effects of the Invention] The present invention has the following effects because it is constructed and operates as described above. 1. It can be opened very easily with a simple operation of folding around a straight cut. In addition, since the opening is clearly defined by the peripheral cut and the straight cut, it is extremely easy for the elderly to handle, and the stored solid matter can be easily taken out.

2. There is no pressing force applied to the stored solids during the opening operation, and the opening is only partially opened without opening the entire surface, so that the solids may pop out and fall. Absent.

3. Since no pressing force is applied to the stored solids, the solids such as tablets are not damaged by the opening operation. For this reason, especially in the case of pharmaceuticals, tablets and the like can be manufactured in a soft state so that the medicinal effect can be quickly and reliably exerted.

4. Of the adhesive part between the molded sheet and the sealing material, it is opened simply by peeling off the sealing part between the molded part and the peripheral cut, and the sealing material is not broken, so when removing solids such as tablets, seal The pieces of wood are not released
It is not accidentally taken with a pill.

5. The entire size of the blister package is relatively large, and the opened portion is clearly defined by the peripheral cut and the straight cut. Therefore, accidental ingestion of the blister package as it is can be prevented, and an accident can be prevented.

6. Since only a part of the opening of the molded part is opened, the molded part can be formed large while keeping the unsealing operation simple.
Accordingly, since a plurality of solid substances can be accommodated in one package by forming a large molded portion, a plurality of the same tablets or different kinds of tablets to be taken at one time are accommodated in one package, particularly in the case of pharmaceuticals. This makes it possible to take out the entire dose in a single opening operation, which greatly simplifies the operation of preparing for taking.

7. If the gripping part is provided on the molded sheet at a position more outward than the peripheral cut, this part can be securely held at the time of opening operation, so the sealing part between the peripheral cut and the molded part is easy Can be peeled off.

8. Forming multiple molded parts on the molded sheet,
Assuming a virtual straight line traversing each opening of each molded part, if peripheral cuts are formed on one side of this virtual straight line, the sealing parts of a plurality of molded parts can be opened simultaneously. For this reason, even if tablets and the like cannot be stored in the same molded part until immediately before taking them, they can be stored in separate molded parts, respectively, and all necessary amounts can be taken out by one operation.

9. In the case where an orthogonal cut is provided from the middle of the peripheral cut to the outer edge of the molded sheet in a direction perpendicular to the virtual straight line, partially remove the sealing part at the time of opening and divide and take out a part of the contents Therefore, when taking the drug, the dose can be adjusted according to the age and symptoms of the patient.
