Description

  The present invention relates to a packaging bag in which a plurality of articles to be packaged, particularly liquid substances, are separated from each other until the start of use, and can be merged quickly and easily at the time of use and can be mixed uniformly.

  For drugs and chemicals, when different types of contents are mixed in advance in one bag, the state of the contents may change over time. About such a thing, it is necessary to leave each content isolated until just before use, and to fully mix each content at the start of use.

  Conventionally, at the start of use, many techniques have already been proposed for a packaging bag that is used by mixing objects to be packaged and stored separately in one packaging bag (hereinafter, described as an example of “liquid”). For example, in Patent Document 1, a part of the divided seal part that divides and separates the inside of the packaging bag is provided with a resin layer having no affinity with the fusion resin layer of the film constituting the bag, and the temporary fusion part is provided. A packaging bag is disclosed that is formed and can be used when the bag is pressed to release the temporary fused portion so that the bag can be opened.

JP 2013-166579 A

  The technique disclosed in Patent Document 1 is to select the conditions such as the resin layer forming the temporary fused portion, the fusion width of the temporary fused portion, and the shape thereof, thereby reducing the peel strength of the temporary fused portion. Proposes a way to adjust. However, in this method, there is a problem that there are many problems to be solved for practical use because it is very time-consuming, such as changing the conditions finely according to the specifications of the contents and bags.

  By the way, in recent years, dressings in small bags for use in salads and the like have been sold in supermarkets, convenience stores, and the like, and the dressings have the property of separating aqueous solution and oil. Therefore, it is necessary to sufficiently mix the aqueous solution and the oil by shaking the sachet immediately before use, but if it is weak, sufficient mixing cannot be performed, for example, only the oil is dispensed in advance. Sometimes. Therefore, it is desired to develop a small bag that can easily stir the article to be packaged in the bag.

  Therefore, the object of the present invention is to hold a plurality of types of contents in an isolated state until the start of use, and the contents may be mixed due to an impact during transportation or a load due to stacking of packaging bags. On the other hand, at the start of use, the packaging bag can be mixed easily by pressing the contents into the storage chamber with fingers, and in particular, the contents can be uniformly mixed by simply stirring the mixed contents. Is to provide.

As a result of intensive studies to achieve the above object, the inventors have arrived at the present invention according to the gist configuration described below. That is, the present invention is a packaged article formed of a single laminated film or a plurality of laminated films folded in the width direction and surrounded by a peripheral seal portion formed on the peripheral edges of the laminated films that are overlapped with each other. In the packaging bag in which the storage space is partitioned into a plurality of storage chambers by the partition seal part,
The partition seal portion is constituted by a normal seal portion and a weak seal portion formed at least one or more in the normal seal portion,
It is proposed that a perforated seal portion extending along the partition seal portion is provided in at least one of the storage chambers partitioned by the partition seal portion at a position spaced from the partition seal portion.

In the packaging bag,
(1) When the perforated seal portion presses the storage chamber and applies the pressure of the article to be packaged to the side edge of the partition seal portion, the gap between the two laminated films on the side edge That the angle to be formed is 180 ° or less,
(2) In the perforated seal part, the side edge on the side adjacent to the partition seal part is separated from the side edge of the partition seal part by 1 mm or more.
(3) The perforated seal portion has a gap formed between the seal portions of 1 to 50 mm.
(4) The perforated seal portions extending in the width direction of the packaged article storage space are separated from upper and lower edges of the packaged article storage space by 10% or more of the total length of the packaged article storage space. Being provided in a position,
(5) The perforated seal portion extending in the length direction of the package storage space is 10% or more of the total width of the package storage space from the left and right edges of the package storage space. Being provided in a spaced position,
(6) The partition wall seal portion includes two or more weak seal portions and two or more normal seal portions, and the seal portions are alternately arranged.
Is a more preferable solution.

In the packaging bag of the present invention having the above-described configuration, the packaged article storage space is partitioned into a plurality of storage chambers by a partition seal portion that is at least partly formed of a weak seal portion, and in the partitioned storage chambers. By providing a perforated seal portion extending along the partition seal portion at a position spaced from the side edge of the partition seal portion, the partition seal is pressed by the pressure of the object to be packaged by pressing against one storage chamber. When the weak seal portion provided in the part is peeled off, the packaged material is injected so as to diffuse through the plurality of narrow gaps provided between the seal parts of the perforated seal part into the other storage chamber. Will be.
That is, according to the packaging bag of the present invention, the object to be packaged in the storage chamber can be vigorously injected into the other storage chamber through a plurality of narrow gaps by pressing the storage bag. This makes it possible to effectively mix and agitate the objects to be packaged.

  Further, in the present invention, when the gap between the seal parts of the perforated seal part is 1 to 50 mm, preferably 3 to 25 mm, the resistance when the packaged object passes through the gap becomes appropriate, The packages can be effectively mixed and agitated by being jetted so as to smoothly pass through the gap and diffuse into the other storage chamber without backflow.

  Further, according to the present invention, by providing the perforated seal portion in each storage chamber partitioned by the partition seal portion, a load may be unexpectedly applied to the packaging bag during transportation or the like. Since the perforated seal portion can relieve the pressure of the article to be packaged toward the partition seal portion, it is possible to prevent unexpected peeling of the weak seal portion provided in the partition seal portion.

  In addition, peeling of the weak seal portion of the isolation seal portion is affected by an expansion angle (hereinafter also referred to as “seal edge angle”) formed between two overlapping laminated films on the side edge of the partition seal portion. The larger the seal edge angle, the easier it is to peel off. In contrast, in the present invention, since the perforated seal portion provided in the vicinity of the partition seal portion can suppress an increase in the seal edge angle as described above, an error in the weak seal portion can be prevented. Separation can be effectively prevented.

  In the present invention, the perforated seal portion is provided at a position where the seal edge angle is 180 ° or less, preferably 30 to 120 °, and / or the perforated seal portion is the partition wall seal. By providing the side edge on the side adjacent to the side part at least 1 mm, preferably 3 to 15 mm away from the side edge of the partition seal part, it is possible to more effectively prevent erroneous peeling of the weak seal part. In addition, the objects to be packaged can be ejected vigorously from the gaps between the seal parts of the perforated seal part, and the objects to be packaged can be uniformly mixed and stirred.

  Furthermore, in the present invention, the perforated seal portion is provided at a position separated from the upper and lower end edges or the left and right side edges of the packaged article storage space by 10% or more of the total length or the entire width of the packaged article storage space. Thus, when the storage chamber is pressed, a sufficient pressure can be applied to the package, and the weak seal portion provided on the partition wall seal can be easily peeled off with a finger pressing force. The effect of agitation by passing through the communication path formed by peeling off the weak seal portion can be improved.

  In the present invention, the partition wall seal portion is a combination of two or more weak seal portions and two or more normal seal portions, and the normal seal portions and the weak seal portions are alternately arranged, so that the In addition, it is possible to prevent the load load due to an impact during handling or the like from being concentrated only on the weak seal portion, and to prevent erroneous opening more effectively, and by one push to one storage chamber, Can be ejected vigorously into the other storage chamber through a plurality of communication pipes formed in the partition seal portion by peeling off the weak seal portion. Can be mixed and stirred.

  As described above, when the partition seal portion is configured by a combination of the weak seal portion and the normal seal portion, the separation strength of the partition seal portion is the normal seal without adjusting the fusion strength of the weak seal portion. By changing the ratio (pitch, etc.) between the portion and the weak seal portion, it is possible to suppress unintentional peeling during handling or the like, while it can be adjusted to peel off due to the pressure of the object to be wrapped by pressing with a finger or the like .

It is a figure which shows one Embodiment of the packaging bag of this invention. It is a figure explaining the method to mix and stir the to-be-packaged goods in the two storage chambers provided in the packaging bag of FIG. It is the elements on larger scale which show other embodiment of a perforated seal part. It is a figure which shows other embodiment of the packaging bag of this invention. It is sectional drawing in the III-III position of FIG. It is a figure which shows other embodiment of the packaging bag of this invention.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows an embodiment of a packaging bag according to the present invention. The packaging bag 1 includes two laminated films having a laminated structure including two or more layers including a sealant layer, and the sealant layers are connected to each other on the inner surface. The outer peripheral edges of the four sides are sealed as shown by hatching in the figure by heat sealing, impulse sealing, high frequency welder sealing or ultrasonic sealing, and other known sealing methods. It is. The packaging bag 1 has a storage space 2 for a packaged object on the inner side by an outer peripheral seal portion. In this embodiment, a four-side seal type sachet is shown, but the present invention is not limited to this, and various types such as a three-side seal bag, a back-sealed seal bag, a gusset bag, a stand pack, etc. Can do.

  The storage space 2 of the packaging bag 1 is further divided into a first storage chamber 2a and a second storage chamber 2b by a partition seal portion 3 provided at a substantially central position in the width direction in the figure, and each storage chamber 2a, In 2b, different packages, for example, water-soluble components mainly composed of soy sauce and oil components such as salad oil are separately filled.

  In the illustrated embodiment, the packaging bag 1 is provided with one partition seal 3 and the storage space 2 is divided into two. However, the present invention is not limited to this. A plurality may be provided and partitioned into a plurality of storage rooms.

  As shown in FIG. 1, the partition seal portion 3 of the packaging bag 1 is provided at a normal seal portion 3a having the same high sealing strength as the outer peripheral seal portion of the packaging bag 1 and at the center in the length direction. The normal seal portion 3a is preferably composed of a weak seal portion 3b having a seal strength of about 50% or less. The weak seal portion 3b can be peeled off by the pressure of the liquid package, and preferably has a seal strength of 2 to 20 N / 15 mm width, more preferably 5 to 15 N / 15 mm width, and the seal of the normal seal portion 3 a. The width is preferably the same as the width or narrower than the seal width.

  The seal width of the partition wall seal portion 3 is not particularly limited, but may be 1 mm or more, preferably 3 to 10 mm, as described later by pressing the packaging bag 1 with a finger to weakly seal the portion 3b. It is easy to adjust the pressing force when peeling only the film.

  Further, the formation position, number and shape (rectangular shape, circular shape, polygonal shape, trapezoidal shape, etc.) of the weak seal portion 3b are not particularly limited, and the side edge of the weak seal portion 3b shown in FIG. The length h may be 1 mm or more, and all the partition seal portions 3 may be constituted by weak seal portions 3b.

  Further, as shown in FIG. 1, the packaging bag 1 of the present embodiment has a perforated seal portion extending in parallel with the partition wall seal portion 3 at a position spaced from the side edge of the partition wall seal portion 3 in the second storage chamber 2b. 5 is provided. In the figure, the perforated seal portion 5 is provided in parallel with the partition wall seal portion 3, but the perforated seal portion 5 may be formed along the partition wall seal portion 3. You may incline with respect to the seal part 3, and may provide.

  The perforated seal portion 5 is composed of two or more seal portions 5a (in FIG. 1, it is composed of five seal portions 5a) in order to exhibit the functions of mixing and stirring the package to be packaged as will be described later. Each seal portion 5a has a sealing strength comparable to that of the normal seal portion 3a of the partition wall seal portion 3, and does not peel off at about the pressure of the packaging object when the storage chambers 2a and 2b are pressed with fingers. And

  In the packaging bag 1, as shown in the drawing explaining the usage method of FIG. 2, when the first storage chamber 2 a is pressed with a finger, the article A to be packaged filled in the first storage chamber 2 a is pressurized. Then, the weak seal portion 3b of the partition wall seal portion 3 is peeled off by the pressure by the article to be packaged A.

  With the peeling of the weak seal portion 3b, the article A to be packaged in the first storage chamber 2a is pushed out into the second storage chamber 2b. At this time, the article A to be packaged is placed in the second storage chamber 2b. By passing through a plurality of gaps 4 formed between the seal portions 5a of the perforated seal portion 5 provided, the second storage chamber 2b is injected with a high pressure, whereby the second storage chamber 2b. Inside, the article to be packaged A and the article to be packaged B are mixed and stirred.

  Furthermore, if the 2nd storage chamber 2b is pressed, the mixture of the to-be-packaged item A and the to-be-packaged item B is moved into the 1st storage chamber 2a, and this operation is repeated, it will be packed with a more uniform concentration Can be mixed and stirred, for example, it can be suitably used for an article to be packaged such as dressing that needs to be stirred immediately before the start of use.

  Here, the perforated seal portion 5 is formed such that the length d of the gap 4 formed between the seal portions 5a shown in FIG. 1 is 1 to 50 mm, preferably 3 to 25 mm. Thereby, when the storage chambers 2a and 2b are pressed with fingers, the resistance when the articles A and B are moved to the partition wall seal portion 3 through the gap 4 can be made moderate. The portion 5a is not peeled off, and the articles A and B are injected so as to smoothly pass through the gap 4 and diffuse into the other storage chamber without causing a backflow from the gap 4. The packages A and B can be mixed and stirred.

  Each of the seal portions 5a of the perforated seal portion 5 has a rectangular shape as shown in FIG. 1, (a) a circular shape, (b) a triangular shape, (c) a trapezoidal shape as shown in FIG. As shown in the figure, the same shape may be aligned, and different shapes may be used in combination. In addition, the length and width of each seal portion 5a are not particularly limited, but preferably, when the length is 2 to 50 mm and the width is 3 to 15 mm, the effect of the mixing and stirring is further improved. Can be demonstrated.

  Further, the perforated seal portion 5 is provided at a position where the shortest distance L from the left and right side edges in FIG. 1 of the package storage space 2 is 10% or more of the total width W of the package storage space. Is preferred. This is because if the distance L is less than 10%, the capacity of the storage chambers 2a and 2b to be pressed is too small, and the effect of stirring the package by pressing the storage chambers 2a and 2b may not be sufficiently obtained. There is.

Next, FIG. 4 shows other embodiment of the packaging bag 1 of this invention, and in this packaging bag 1, both sides of the partition seal part 3 in the 1st storage chamber 2a and the 2nd storage chamber 2b are shown. A perforated seal portion 5 extending along the partition seal portion 3 is provided at a position spaced from the edge.
In this case, in addition to the effect of mixing and stirring the above-described packaged object A and packaged object B by the perforated seal portion 5, the perforated seal portion 5 presses the storage chambers 2a and 2b. In this case, the pressure of the object to be packaged toward the side edge of the partition wall seal portion 3 is relieved, and the high pressure of the object to be packaged is not directly applied to the side edge of the partition wall seal portion 3, and the partition wall seal The effect that the misopening of the part 3 can be prevented can be expected.

  The weak seal portion 3b of the isolation seal portion 3 is peeled off as shown in a sectional view (FIG. 5) in III-III of FIG. The influence of the expansion angle (seal edge angle θ) of 6b is large, and the larger the seal edge angle θ, the easier it is to peel off. Against this, by providing the perforated seal portion 5 as described above, the degree of freedom in the opening direction (inflating direction) of the two laminated films 6a and 6b is reduced, and the seal edge angle θ is reduced. Since the rise is suppressed, there is no possibility that the weak seal portion 3b is peeled off unexpectedly during handling.

  When the perforated seal portion 5 presses the storage chambers 2a and 2b and applies the pressure of the articles A and B to the side edge of the partition seal portion 3, the seal edge angle θ is 180 ° or less, When it is provided at a position that is preferably in the range of 30 to 120 °, it is possible to effectively prevent the unexpected peeling of the weak seal portion 3b, and to separate the packaged items between the seal portions 5a. 4 can be ejected vigorously, and the items to be packaged can be effectively mixed and stirred.

  Similarly, when the perforated seal portion 5 is provided such that the distance α (FIG. 4) from the side edge to the side edge of the partition seal portion 3 is 1 mm or more, preferably 3 to 15 mm. Can effectively prevent unintentional peeling of the weak seal portion 3b, and can jet the packaged material through the gap 4 between the seal units 5a. Can be mixed and stirred.

FIG. 6 shows another embodiment of the packaging bag of the present invention.
In this packaging bag 1, the partition seal part 3 is composed of a plurality of weak seal parts 3b and normal seal parts 3a provided alternately. Therefore, compared with the case where the weak seal portion 3b is provided only at one place of the partition seal portion 3, the concentration of the pressure of the article to be packaged on the weak seal portion 3b is suppressed. Can be prevented.

  Further, the peel strength of the partition wall seal portion 3 can be easily adjusted by changing the formation ratio of the weak seal portion 3b and the strong seal portion 3a. By changing the number, length, etc. of the portion 3b and the strong seal portion 3a, the separation strength of the partition wall seal portion 3 can be easily separated by pressing with a finger or the like, while unexpected separation during handling is possible. It can be set to prevent. Further, after the weak seal portion 3b is peeled off, the articles A and B are urged between the first storage chamber 2a and the second storage chamber 2b through a plurality of communication pipes formed in the peeling portion. Since it is sprayed well, the articles A and B can be sufficiently mixed and stirred.

  According to the packaging bag of the present invention, the same type or different types of contents are held in isolation until the start of use, and the contents are uniformly mixed in the packaging bag by pressing with fingers at the start of use. Therefore, it can be used in a wide range of fields such as hair dyes and adhesives, and other chemicals and chemicals in addition to those that need to be stirred just before the start of use such as dressing.
