Description

  The present invention relates to a resealable sealed packaging container, and in particular, contains paper or cloth containing a volatile component such as a patch containing a medicinal component that easily volatilizes such as menthol, and continues for a certain period of time. In particular, the present invention relates to a resealable carton suitable for an application to be used and a method of manufacturing a package using the carton.

  We know products that contain multiple sheets of paper or cloth soaked with water, alcohol, or other volatile liquids or drugs, such as wet tissue, and that are used continuously for a certain period after opening. It has been.

  In these products, it is possible to reseal the container outlet after taking out a part of the product so that the volatile substances contained in the contents are not dissipated after opening and the functionality of the product is deteriorated. There are a lot of things.

The most common method of resealing is to cover the take-out opening with a large adhesive sheet. When using, peel off the adhesive sheet and take out the contents. After use, put the adhesive sheet on the take-out opening. The required sealing performance is ensured by crimping and resealing.
As the material and shape of these containers, for example, if it is a wet tissue, a flexible packaging bag type container using a soft packaging material is most commonly used, and a back-attached palm bag or a back-attached gusset bag is used. There are many.

These resealable containers using flexible packaging bags have an essential problem that wrinkles are likely to occur around the opening, particularly when the contents are reduced, and the sealing performance is impaired.
In addition, as the contents are reduced, the bag becomes thin, so that there is a problem that the appearance is poor. Furthermore, since the flexible packaging bag container is not self-supporting, it is inferior in terms of the display effect at the store.

  If a container with a soft packaging bag container is used inside a paper outer box, it is possible to eliminate this problem of appearance and display effect. In addition, it is troublesome to open or seal both the outlet of the container and the inner container, and handling is complicated.

In order to solve this problem, Patent Document 1 proposes a moisture-proof container that solves the problem of appearance and display effect, and that can open the inner bag at the same time when the outer box is opened.
That is, it consists of an outer box made of cardboard or the like and an inner bag made of a moisture-proof material, and a tear-off line is opened across the top plate and front plate of the outer box, and the inner bag is made of the moisture-proof material It has an adhesive part between its ends on the front and back, and the inner bag is attached to the outer box so that the adhesive part is located at the opening position inside the top plate of the outer box It is a simultaneous opening moisture-proof container.

  However, the simultaneous opening moisture-proof container described in Patent Document 1 has a structure that cannot be resealed once opened, and therefore can only be used for applications where the contents are used up at once. It was.

On the other hand, it is easy to open and can be resealed even after it has been opened, and it does not deteriorate the required sealing performance or appearance even for contents containing volatile substances. As a packaging container, Japanese Patent Application No. 2011-243245 proposes the following sealed packaging container.

  That is, a packaging container comprising an inner bag and an outer box for storing the inner bag, the inner bag is formed of a laminated body that prevents permeation of volatile substances, and an opening for taking out the contents An opening half-cut line having a closed shape that forms the opening, an opening reinforcing sheet that reinforces the periphery of the opening, and an adhesive sheet for resealing that covers the opening and the opening reinforcing sheet, the laminate The part surrounded by the half-cut line of the opening is adhered to the re-sealing adhesive sheet, and the outer box is connected to the bottom plate and the back plate sequentially connected from the bottom plate via the crease line. The back plate has a face plate and a top plate, and further includes a margin continuously provided via a crease line from the bottom plate, and left and right side plates and a front plate provided continuously from the top plate via the crease line. , And the left and right side plates, and the front plate Folding crease lines are provided for folding to the side, the top plate has a lid plate formed by a lid half-cut line, and the inner bag is bonded to the bottom plate and the top plate. The re-sealing adhesive sheet is adhered to the lid plate, and the opening half-cut line of the inner bag is opened when the lid plate is opened by cutting the lid half-cut line of the outer box. The packaging container is characterized in that the opening of the inner bag is opened simultaneously.

According to this packaging container, the portion surrounded by the opening half-cut line that forms the opening of the inner bag is adhered to the resealable adhesive sheet, and the resealable adhesive sheet is a lid plate. When the cover plate of the outer box is opened, the opening of the inner bag is also opened at the same time. For this reason, the trouble which opening requires can be saved and it can open very easily.
In addition, the resealable adhesive sheet, which is the means for resealing the inner bag, is adhesively fixed to the cover plate of the outer box, so that the flatness of the resealable adhesive sheet is maintained and sealed when resealed. It is easy.

  However, even with this packaging container, the inner bag collapses when the content decreases, and even if it tries to reseal, the pressure-sensitive adhesive sheet cannot be uniformly and strongly pressed against the surface of the inner bag and the resealability is poor. The problem still remained.

  A resealable carton (1) according to the present invention is a packaging container comprising an inner bag (20) for storing a content (30) containing a volatile substance and an outer box (2) for storing an inner bag. It is.

  The resealable carton (1) according to the present invention has an inner bag (20) that prevents volatilization of volatile substances contained in the contents and an outer box (2) that accommodates the inner bag (20). The storage stability is good and the appearance is also excellent.

  Examples of the contents that can be stored in the resealable carton (1) according to the present invention include, for example, a wet tissue containing moisture, an alcohol and a fragrance that are more volatile than water, and menthol. For example, a patch containing a medicinal component that easily volatilizes.

  FIG. 1 is a perspective view showing an embodiment of a carton according to the present invention. When opening this carton, the opening knob (13) on the back side of the figure (see FIG. 2) is pushed, and the lid plate (9) is cut along the lid perforation line (17).

  The area where the adhesive sheet (24) for resealing is adhered to the back surface of the lid plate (9) when cut along the lid perforation line (17) and exceeds the crease line (11) on the top plate (4) (See FIG. 2), the cover plate (9) is re-sealed from the opening reinforcing sheet (23) adhered to the outer periphery of the opening half-cut line (25) of the inner bag (20). ) And begin to leave.

  When reaching the opening half-cut line (25), the film (27) of the opening of the inner bag (20) in the region of the opening (26) surrounded by the opening half-cut line (25) of the inner bag (20) ) Is removed from the inner bag (20) together with the cover plate (9) while being cleaved at the opening half-cut line (25) and attached to the resealable adhesive sheet (24). An opening (26) for taking out an object is formed.

FIG. 2 is a perspective view showing the contents taken out from the resealable carton according to the present invention.
The shape and size of the opening (26) of the inner bag (20) are appropriately determined depending on the shape and size of the contents (30) and properties such as stiffness.

The contents (30) are taken out from the opening (26) in the direction of taking out (32) in the state shown in FIG.
After taking out the necessary amount, it can be easily resealed by reversing the above procedure.

In the resealable carton of this embodiment, since the reinforcing member (40) provided with the spacer (41) is inserted inside the inner bag (20), the outer size of the inner bag (20) is the content ( 30) The change in the appearance and workability of the inner bag and the outer box is almost the same even with the decrease in 30).
Not only the presence of this reinforcing member (40), but also the opening reinforcing sheet (23), which is the inner bag side surface for pressing the resealable adhesive sheet (24) when resealing, is smooth from the back surface. Can be re-sealed reliably, reducing the risk of content deterioration due to sealing leakage.

The inner bag (20) is formed by molding a laminate as shown in FIG. 4 that prevents permeation of volatile substances. An opening half-cut line (25) having a closed shape for forming an opening (26) for taking out the contents (30), and an opening reinforcing sheet for reinforcing the periphery of the opening as shown in FIG. 23) and an adhesive sheet (24) for resealing which covers the opening (26) and the opening reinforcing sheet (23).
The opening reinforcing sheet (23) and the resealable adhesive sheet (24) are positioned so as to cover the opening (26) in this order on the laminate as the base material of the inner bag as shown in FIG. Affixed.

  The inner bag (20) in the embodiment shown in FIG. 4 is a back-bonded palm bag in which a single laminated body is formed into a cylindrical shape by a palm seal portion (22) and then a seal portion (21) is formed. It may be a back-attached gusseted bag or a simple four-sided bag.

As a laminated body which comprises an inner bag (20), the packaging material generally used for a flexible packaging bag can be used.
Depending on the type of volatile component contained in the contents, it is desirable to provide a barrier layer having a property of blocking this.

As the barrier layer, an aluminum foil, an aluminum deposited film, a gas barrier film deposited with a metal oxide, or the like is used.
A sealant layer is disposed on the inner surface side of the laminate so that it can be processed into a bag shape by heat sealing.

The portion surrounded by the opening half-cut line (25) of the laminate, that is, the portion forming the opening (26) is bonded to the pressure-sensitive adhesive surface of the resealable pressure-sensitive adhesive sheet (24).
In addition, as the adhesive force of this part, if the opening part half-cut line (25) is formed appropriately, the original adhesion which the pressure-sensitive adhesive sheet for re-sealing (24) has can be used without using a special adhesive. Sometimes power alone is enough.

  As shown in FIG. 5, the re-sealable carton outer box (2) of the present invention is usually made of paperboard, and a bottom plate (8) and a crease line (11) from the bottom plate (8). A back plate (7) and a top plate (4) that are successively arranged via the bottom plate (8), a margin (10) that is arranged from the bottom plate (8) via a crease line, and a top plate (4) The left and right side plates (6) and the front plate (5) are connected to each other via a crease line (11).

On the outer surface of the outer box (2), necessary information such as pictures and characters indicating the contents, instructions for use, etc. is printed and formed, and a transparent protective layer is provided as necessary.
Moreover, you may provide printing and a transparent protective layer as needed also on the inner surface side of an outer box (2).

A reinforcing member (40) is inserted in the inner bag used in the resealable carton (1) of the present invention to maintain the thickness of the outer box having a vacant opening.
An example of this reinforcing member is shown in FIGS.
FIG. 6 is a development view of an example of a reinforcing member. FIG. 7 is an assembly drawing thereof. FIG. 8 is an assembly view of the contents storage state.
The material and manufacturing method of the reinforcing member are not particularly limited, but here, description will be made assuming that the reinforcing member is molded as shown in the development view of FIG. 6 and assembled as shown in the assembly view of FIG.

  As shown in FIG. 6, a window (42) for taking out contents is provided at a substantially central portion on a plastic substrate (46) having a thickness D, and a spacer (height H) is formed at a symmetrical position below the center of the top and bottom. The plate provided with 41) is bent 180 degrees toward the spacer (41) side with the top and bottom center line as an axis to form a reinforcing member (40) having a thickness (H + 2D) in the shape of FIG.

At this time, a recess (45b) is provided on the upper portion of the spacer (41), and a projection to be fitted with the recess is provided on the plastic substrate (46) at a symmetrical position with respect to the top and bottom center line so that the spacer can be assembled without distortion.
The window (42) may be assembled if the shape and size of the window (42) are approximately the same as the opening half-cut line (25), and as shown in FIGS. 2 and 8, the contents can be removed without inconvenience in the direction (32). I just need it.

Even when the content is reduced, the reinforcing member (40) does not reduce the thickness of the inner bag, does not wrinkle around the opening, and exhibits the effect that the sealing performance is maintained.
When the lid plate portion of the outer box is pressed during resealing, it is supported by the reinforcing member that maintains the thickness of the outer box from the inside of the inner bag, and the flatness of the top plate is maintained.
For this reason, the resealability is improved, and the carton appearance is maintained well even after the contents are reduced.

  The top plate (4) has a lid plate (9) formed by a lid perforation line (17), and the inner bag (20) is bonded to the bottom plate (8) and the top plate (4), The said sealing sheet for resealing (24) is adhere | attached on the cover plate (9).

Therefore, as shown in FIG. 2, when the lid perforation line (17) of the outer box (2) is cut open and the lid plate (9) is opened, the opening half-cut line (25) of the inner bag (20) Is opened and the opening (26) of the inner bag is opened simultaneously.
At this time, the film (27) in the opening corresponding to the inside of the opening half-cut line (25) of the laminate forming the inner bag (20) is covered with the re-sealing adhesive sheet (24) and the cover plate (9). Move to the back of the.

Thus, when the cover plate (9) of the outer box (2) is opened, the opening (26) of the inner bag (20) is opened at the same time, which is very convenient.
Moreover, since the film (27) of the opening part which is an inner part of the opening part half cut line (25) of the inner bag (20) moves to the resealable adhesive sheet (24) and covers the adhesive surface, When sealed, it exerts the effect of preventing the adhesive surface from swelling due to components that volatilize from the contents.

In addition, if the adhesive layer of the pressure-sensitive adhesive sheet for resealing (24) is provided with a portion where the adhesive does not exist a little at the beginning of peeling, the beginning of peeling becomes smoother.
In addition, when opening the container, the re-sealing adhesive sheet adhered to the lid plate does not peel off from the opening, and conversely the adhesive between the resealing adhesive sheet and the lid plate is peeled off. It becomes difficult and there exists an effect which the adhesive sheet for resealing peels with a cover plate reliably.

  The hatched portion shown in FIG. 5 indicates the position of the inner bag fixing paste (28). The inner bag (20) and the back side of the outer box (2) are bonded and fixed on the bottom plate (8) and the top plate (4).

  The lid plate (9) is a central portion of the top plate (4), and is opened by using the left and right lid perforation lines (17) as incisions, using the crease line as a hinge portion.

In this embodiment, a part of the front plate (5) is cut by a perforation line to form an opening knob (13) connected to the lid plate (9).
Further, an opening hole (12) is formed in the margin (10) connected to the bottom plate so that the opening knob (13) can be easily lifted during opening.

  The front plate (5) and the margin (10) are bonded only at portions other than the opening knob (13) and the opening hole (12).

  Further, as shown in FIG. 5, in this embodiment, since the side plate (69 is provided with the disassembling perforation line (19) provided on the bottom plate (8), the resealable carton (1) is attached. When discarding after use, the inner bag (20) and the outer box (2) can be separated and discarded efficiently.

Next, the manufacturing method of the package using the resealable carton (1) which concerns on this invention is demonstrated.
As a very general method of manufacturing a package, first, the contents (30) are stored in the inner bag (20), the opening is sealed, and then the outer box (2) is stored. There is a way to seal.

  However, in the case of the resealable carton (1) according to the present invention, it is necessary to accurately align the opening (26) of the inner bag (20) and the lid (9) of the outer box (2). In the conventional general method, accurate alignment cannot be performed.

Therefore, the present inventors have invented a method for manufacturing a package including the following steps and having the third and subsequent steps in this order.
That is, a first step of creating an inner bag in which the filling opening is unsealed. Second step of creating an outer box blank. A third step of adhering and fixing the inner bag to the back side of the outer box blank. A fourth step of creating a packaging container with a built-in inner bag by sacking an outer box blank. A fifth step of sealing the inner bag after opening the outer box and storing the reinforcing member and the contents in the inner bag. This is a sixth step in which the opening of the outer box is sealed to form a package.

According to this method, since the inner bag (20) and the outer box blank (3) can be bonded and fixed in advance, the positions of both can be accurately aligned.
Since the outer box (2) containing the inner bag (20) has been sack pasted, the re-sealable carton (1) is filled with the reinforcing member (40) and the contents (30). This saves time and effort at the stage of filling the contents (30), so that even contents containing easily volatile components can be quickly and safely filled.

9-11 is the perspective explanatory view which showed a part of manufacturing method of the package using the resealable carton (1) based on this invention.
FIG. 9 shows a third step of bonding and fixing the inner bag (20) to the back side of the outer box blank (3).
Moreover, FIG. 10 shows the state after completion of the fourth step in which the outer packaging blank is sack pasted to create a packaging container containing the inner bag.
FIG. 11 shows a state where the outer box is opened and the reinforcing member and the contents are stored in the inner bag in the fifth step.

As shown in FIG. 9, the inner bag (20) is bonded and fixed to the back side of the outer box blank (3) while the filling opening (29) is not sealed.
The inner bag (20) is provided with an opening half-cut line in advance, and the opening reinforcing sheet is adhered to the inner bag while aligning it, and the resealing adhesive sheet (24) is adhered while further aligning. It is.

In this state, since both the inner bag (20) and the outer box blank (3) are planar, alignment is easy.
It should be noted that the seal portion (21) on the opposite side of the filling opening (29) of the inner bag (20) may be unsealed at this stage.

Next, the outer box blank (3) is bent along the crease line and sack pasted, and the margin (10) and the front plate (5) are bonded together to obtain the state shown in FIG.
At this time, the back surface of the resealable pressure-sensitive adhesive sheet (24) and the inner surface of the lid plate (9) are bonded, and the upper surface of the inner bag (20) and the inner surface of the top plate (4) are bonded to the inner bag. It is made to adhere by fixing glue (28).

  As a method of bonding the back surface of the resealable pressure-sensitive adhesive sheet (24) and the inner surface of the lid plate (9), for example, a pressure-sensitive adhesive or heat-sensitive adhesive is previously applied to the back surface of the resealable pressure-sensitive adhesive sheet (24). There is a method of applying an adhesive.

Next, as shown in FIG. 11, the outer box (2) in which the sacking is completed is opened, the filling opening (29) is opened, and the reinforcing member ( 40) is filled with the contents (30) sandwiched.
The reinforcing member (40) may be prepared by preparing a plastic such as polystyrene resin in advance by a known method such as injection molding, and assembling it and aligning it with the contents (30).
Finally, the filling opening (29) is sealed, and the side plate (6) of the outer box (2) is adhered and sealed to complete the package.

  In addition, when the seal part (21) of the inner bag (20) is in an unsealed state, it may be sealed immediately before filling the reinforcing member (40) and the contents (30), or the filling opening (29) may be sealed at the same time as sealing.

  As described above, the resealable carton according to the present invention is extremely suitable for applications in which contents containing volatile components are stored and used continuously for a certain period of time.
