JP5590489B2 - Sealing bag for packaging - Google Patents

Description

  The present invention relates to an improvement of a sealing bag for packaging such as a pouch from which a stored item having adhesiveness in part can be easily taken out.

Conventionally, a patch 10 to which a pressure sensitive adhesive such as a transdermal absorbent is applied typically has a substrate / adhesive layer (transdermal absorbent-containing pressure sensitive adhesive layer) / separator (release sheet) as shown in FIG. The separator such as a silicone-coated film is used until the pasting body is pasted due to its characteristics.
Therefore, when the adhesive body is stored in a packaging bag such as a pouch, the end surface of the adhesive layer is exposed, and therefore the separator attached to the wide surface of the adhesive layer is attached to the wide surface of the adhesive layer. There is a risk of problems such as peeling off at the top or smoothing out of the patch from the bag.
Therefore, as a method for applying a release agent to the inside of a film of a packaging bag to prevent sticking, JP-A-2005-328928 discloses a packaging bag for storing a patch and a patch package.

That is, the above-mentioned patch storage packaging bag and patch package include a heat-fusible resin layer for storing a patch formed by laminating a patch layer containing a drug and a release paper on a base material. A packaging bag configured by heat-sealing a pair of sheets having at least a part of the heat-sealing portion of the packaging bag, wherein the heat-sealing resin layers of the sheet are directly heat-sealed. In addition, an adhesion preventing layer made of a release agent is provided on a part of the inner surface of the sheet, and the adhesion preventing layer extends to the heat fusion part of the packaging bag, or the adhesion preventing layer. Is composed of colored.
As a result, the sealing part has a high sealing property, and effectively suppresses the volatilization of the drug contained in the patch, and also when the patch is removed from the packaging bag, it can be quickly removed without peeling off the release paper. it can.

JP 2005-328928 A

Due to the nature of packaging pouches, tubular films are required to seal four sides when sealing two films to form a packaging bag and at least three sides open when folding one film. In the case of using, the two sides are similarly sealed by heat sealing or the like.
For this reason, when a release agent such as silicone is applied to the entire inner surface of the film constituting the packaging bag of the pouch, heat sealing cannot be performed and the function as a pouch may not be achieved.
Therefore, in order to solve the above problem, a zone coat or part coat technique is used to apply a release agent such as silicone only to a necessary portion.
When a release agent such as silicone is applied to the inner surface of the film, since the silicone is colorless, the boundary with the uncoated part cannot be visually recognized.
Therefore, in patent document 1, ingenuity, such as coloring, is performed in order to visually recognize the coated area of the release agent.
However, in the case of coloring, it is necessary to confirm in advance whether the components contained in the colorant have an adverse effect on the stored items such as the patch.
The present invention was devised in view of the above circumstances, and the problem to be solved is that the inner surface of the film of the packaging bag is coated with a release agent colored along the inner periphery of the seal portion. Forming a line part and visually recognizing the colored line part by forming a transparent area part coated with a transparent release agent that does not affect the stored matter such as a patch on the entire inner side of the colored line part Then, it is providing the sealing bag for packaging which enabled it to confirm the overlap of the seal | sticker part of the said packaging bag.

In order to achieve the above object, the present invention provides a first aspect of the present invention.
An uncoated part where the anti-adhesive agent is not applied is provided on the inner surface of the sheet of the packaging sealing bag that seals the stored items along the outer periphery, and the part other than the uncoated part is attached. As an inhibitor coating department,
The anti-adhesive agent coating part is colored on the inner periphery surrounded by the colored coating part and the colored coating part coated with the anti-adhesive agent colored along the uncoated part on the outer periphery And a transparent color coating portion coated with an anti-adhesive agent that does not contain an agent.
In the invention of claim 2,
The uncoated part is formed in a rectangular frame shape along the outer peripheral edge of the sheet, and the colored coated part is formed in a line shape along the inner peripheral edge of the uncoated part. A transparent color coating portion is formed on the inner side surrounded by the portion.
In the invention of claim 3,
The heat seal formed on the uncoated part is made of an easy peel.
In the invention of claim 4,
A colored coating portion and a transparent color coating portion are simultaneously formed using a colored adhesion preventing agent and a transparent adhesion preventing agent.

Since the anti-adhesive agent coating part consists of a colored coating part on the outer peripheral side and a transparent color coating part formed on the entire inner side thereof, the color coating part visually checks the overlapping of the heat seal points. Can be confirmed.
Further, since the stored item is contacted by the transparent color coating portion, impurities such as a colorant do not come into contact with the stored item, so that the quality of the stored item can be maintained.
In addition, it is possible to zone-coat the colored coating part and the transparent color coating part at the same time by coating with the colored anti-adhesive agent and the transparent anti-adhesion agent, thereby saving labor and cost. be able to.

  Hereinafter, a preferred embodiment of the sealing bag for packaging according to the present invention will be described with reference to the drawings.

[Sealing bag for packaging]
The packaging sealing bag 1 of Example 1 heat seals the peripheral part of a pair of synthetic resin films 2 arranged facing each other, and seals with a patch such as a transdermal absorbent housed therein. (See FIG. 1 (a)).
And on the inner surface of a pair of sheet | seat 2 which comprises the sealing bag 1 for packaging, the uncoated part 3 for performing heat sealing by enclosing with a predetermined width along the peripheral part (outer periphery), and this uncoated An anti-adhesive agent coating part 4 formed on the inner part surrounded by the work part 3 is formed (see FIG. 1B).

The pair of sheets 2 arranged so as to face each other are illustrated as being constituted by separate sheets. However, as described later, in the present invention, a pair of sheets facing each other by folding one sheet into two. Or a surface facing a cylindrical sheet.
Moreover, the kind of plastic film used for a sheet | seat can be suitably selected according to a use, and is not specifically limited.

[Uncoated part]
Heat sealing is performed along the edges of the opened surfaces of the pair of sheets 2 to form a sealed bag.
In this embodiment, the uncoated portion 3 which is a heat seal forming portion is formed in a substantially rectangular frame shape along the peripheral edge portion of the sheet 2, but in this embodiment, the inside of the bag may be sealed and the frame shape is If it is endless, it will not specifically limit.

[Anti-adhesive coating part]
In the pair of sheets 2 constituting the sealing bag 1, the adhesion preventing agent coating portion 4 may be formed on the inner surfaces of both sheets or may be formed on the inner surface of one of the sheets.
This anti-adhesive agent coating part 4 is formed in the whole area | region except the uncoated part 3 which heat seals the said sheet | seat 2. As shown in FIG.
When the uncoated portion 3 surrounds the periphery (four sides in the illustrated example), the anti-adhesive agent coated portion 4 is formed over the entire inner portion surrounded by the uncoated portion 3.

[Coloring coating part]
The anti-adhesive agent coating part 4 includes a line-shaped colored coating part 5 formed along the uncoated part on the outer periphery thereof, and an inner transparent color coating part surrounded by the colored coating part 5 6 (see FIG. 2A).
The colored coating portion 5 is a portion where a colored adhesion preventing agent is applied, and for example, a colored silicone-based adhesion preventing agent containing an appropriate pigment is applied.

Since this colored coating part 5 is formed in a line shape inside the uncoated part 3, it is possible to more visually confirm an abnormality in the overlap of the uncoated part 3.
Here, the line shape is not limited to a continuous one, but may be intermittent at a predetermined interval (see FIG. 2B).

The color to be colored is not particularly limited, and a color that can be identified when applied to the sheet 2 is used.
For example, when the sheet has a translucent color, an identifiable color other than the similar color is used.

[Transparent color coating part]
The transparent color coating portion 6 is a portion where an adhesion preventing agent that does not contain impurities such as a colorant is applied. For example, a transparent silicone-based adhesion preventing agent is applied.
The transparent color coating portion 6 is formed on the surface of the sheet 2 in contact with the stored item 10, but since the colorant and impurities are not present on the contact surface with the stored item 10, the stored item 10 contacts the sheet 2. However, there is no risk of reaction and deterioration (see FIG. 2C).

The colored silicone-based anti-adhesive and the colorless and transparent silicone-based anti-adhesive can be applied in one step at the same time, resulting in cost merit and visual confirmation of the application position of the colored anti-adhesive. it can.
In addition, since the transparent anti-adhesive agent does not contain impurities such as a colorant, it is not necessary to perform a contact test again, and the quality of the contact surface can be guaranteed.

  The packaging sealing bag 1 of Example 2 is a pair of uncoated parts for cutting a cylindrical film 12 crossing the continuous direction and heat-sealing along two opposing outer peripheries opened by the cutting. 3 is formed, and the others are the anti-adhesive coating part 4 (see FIG. 3).

The anti-adhesive agent coating part 4 is formed with a colored coating part 5 along the uncoated part 3, and the other part is a transparent color coating part 6.
Since other configurations are the same as those of the first embodiment, the same components are denoted by the same reference numerals, and the description thereof is omitted.
Also in this case, it is possible to visually confirm the coating position of the colored anti-adhesive agent as in Example 1.
Moreover, the quality of a contact surface can be ensured by using a transparent adhesion preventing agent.

The packaging sealing bag 1 of Example 3 has a structure in which a rectangular film 22 is folded in half and heat-sealed in three directions to seal the stored items 10 (see FIG. 4).
And the substantially U-shaped uncoated part 3 is formed along the outer periphery of the sheet | seat 2 which comprises the sealing bag 1, and it becomes the adhesion prevention agent coating part 4 other than that.

The anti-adhesive agent coating part 4 has a colored coating part 5 formed in a U shape along the uncoated part 3, and the other part is a transparent color coating part 6.
Since other configurations are the same as those of the first and second embodiments, the same components are denoted by the same reference numerals and description thereof is omitted.
Also in this case, it is possible to visually confirm the application position of the colored anti-adhesive agent as in Examples 1 and 2.
Moreover, the quality of a contact surface can be ensured by using a transparent adhesion preventing agent.

In the present invention, it is desirable to use an easy peel method for heat sealing the uncoated part.
Moreover, the structure which the one part overlaps may be sufficient as the heat-sealing of an uncoated part and the colored coating part which contact | connects this (refer Unexamined-Japanese-Patent No. 2005-328928).
In this example, the percutaneous absorbent was exemplified as the stored item. However, it is necessary to apply an anti-adhesive agent such as silicone on the inner surface of the sealing bag, such as a product having other adhesive applied or a product having adhesiveness. All storage items are included.
In addition, it goes without saying that various design changes can be made without departing from the scope of the present invention.

  The present invention can be widely applied to fields related to packaging or containers such as the food packaging field, the medical field, and the industrial field.
