Description

[Detailed explanation of the invention] [Industrial application fields] This invention is applicable to toys, stationery, daily necessities, food,
Related to blister packs used for packaging medicines, cosmetics, etc.

[Conventional technology]

Conventionally, when taking out a product from a blister pack, it was very inconvenient because the entire blister had to be peeled off from the backing paper. In addition, since the adhesive force between the blister and the mount is strong, the surface layer of the mount adheres to the blister, and the product cannot be removed without peeling or breaking the surface layer from the blister. In order to prevent the above-mentioned defects, we devised a way to remove the product from the back side of the backing paper without peeling off the blister by cutting the perforations or notches provided inside the joint of the backing paper that joins the flange of the blister. The technology is already known. Furthermore, a so-called sliding blister pack technique that does not use adhesive has been devised, in which the ends of the mount are inserted into guide grooves formed by bending both ends of the blister to assemble.

[Problem that the invention attempts to solve]

However, when the backing paper has perforations or notches, although it is somewhat effective in that there is no need to peel off the entire blister, it takes time and effort to cut the perforations and notches, and the product may be damaged. There are inconveniences such as difficulty in taking out the device, and no fundamental solution has been found in terms of ease of use. In addition, since the mount is cut along the perforations and notches, the disadvantage of damaging the product information and explanatory diagrams printed on the surface of the mount remains unresolved. Not only are there problems, but the aesthetic appearance of the package has also been damaged.

On the other hand, with the sliding blister pack method that does not use adhesive, the backing paper can be easily removed from the blister, so it is not possible to guarantee that the product is unused. There was a risk of unauthorized use, and there were issues that needed to be resolved in terms of product quality assurance.

[Means for solving problems]

The present invention has been improved in order to eliminate the above-mentioned drawbacks, and after storing the product in the recess of the blister formed by molding a synthetic resin sheet, the blister pack is formed using a blister packaging machine. A cutting line is provided in a part of the flange part to form a separation part, and the cutting line is extended and provided around the flange part of the blister so that the recess can be opened, and the flange part The inner part of the cutting line is subjected to a crimping process, and the cutting part is provided with a protruding knob for cutting operation, if necessary.

[Effect]

Since the present invention is constructed as described above, when opening the package, first pull up the knob protruding from a part of the flange, gradually peel off the flange from the surface of the mount, and then peel it along the cutting line. All you have to do is separate the cutoff part from the other flange parts. Next, the cutting line provided around the flange portion is gradually cut. At this time, since the inner part of the slit line in the flange part is embossed, the adhesive force to the mount is weaker than the outer part. Therefore, as the knob is pulled up and the cutting line provided around the flange part is gradually cut, the inner part of the cutting line in the flange part is easily peeled off from the mount, and the recessed part is opened. You can take out the product.

〔Example〕

The structure of the present invention will be described below with reference to drawings showing one embodiment thereof. As shown in FIG. 1, numeral 1 is a blister made of a synthetic resin sheet, and 2 is a mount. After the product 4 is stored in the recess 3 of the blister 1, it is placed in a blister packaging machine, and when the blister 1 is molded, a flange portion 5 is formed on the outer periphery.

A cutting line 6 is provided in a part of the flange part 5 of the blister 1 to form a separation part 7, and the cutting line 6 is provided in a part of the flange part 5 of the blister 1 so that the recessed part 3 can be opened. Extend and establish a perimeter. The shape of the cutting line 6 does not particularly matter, but for example, as shown in FIG.
As shown in the figure, a wedge-shaped groove or the like having a depth that does not reach the thickness of the blister 1 is suitable. Further, in the flange portion 5, the inner portion 8 of the slit line 6 is subjected to a graining process to form a surface with an uneven pattern. In addition, regarding the ratio of the inner portion 8 to the flange portion 5 and the degree of graining,
It may be selected appropriately in consideration of conditions such as the form of the blister 1 and the mount 2, adhesive strength, and usability.

In addition, if a knob 9 for a cutting operation is provided protruding from the cutting portion 7, the cutting operation becomes easier.

After storing the product 4, the blister 1 and the mount 2 are placed in a blister packaging machine, an adhesive is applied to form an adhesive layer 10, and the flange portion 5 is heated on the surface 11 of the mount 2. Form a blister pack by gluing or high frequency welding.

In another embodiment shown in FIG. 4, a cutting line 6 is provided in a part of the flange portion 5 of the blister 1 to form a wide separating portion 7. In addition,
If a knob 9 for cutting operation is provided protrudingly on the cutting portion 7,
The disconnection operation becomes easier. The cutting line 6 is extended and provided around the other three flange portions 5 so that the recess 3 can be opened. The cutting line 6 can be a wedge-shaped groove with a depth that does not reach the thickness of the blister 1. Furthermore, in the three flange portions 5, the inner portions 8 of the cutting lines 6 are subjected to a graining process. After storing the product 4, the blister 1 and the mount 2 are placed in a blister packaging machine, and the three flange portions 5 are thermally bonded or high-frequency welded to the surface 11 of the mount 2 using an adhesive. Form a blister pack.

[Effect of idea]

As detailed above, the present invention provides a slit line around the flange of the blister, and also applies a graining process to the inner part of the slit line at the flange to make it more adhesive to the mount than the outer part. Since the force is weakened, the product can be taken out very easily and quickly by cutting the slit line from the cut-off part formed in a part of the flange part and opening the recess of the blister. This has the effect of not impairing the beauty of the package.

Furthermore, since the cutting line is formed only on the flange portion, there is no fear that the cutting line will be cut by external force during transportation or display.

Furthermore, it is suitable for mass production, no different from the process of conventional adhesive blister packs, and has the advantage of being able to provide products with a sense of security to consumers, as it also has the effect of preventing unauthorized use of quality assurance. .
