Description

  In the present invention, various liquid or viscous liquid packages such as food and drink, medicines and chemicals can be contained independently in one bag until the start of use, and prior to the start of use The present invention relates to a multi-liquid filled bag used in such a manner that the mixture can be pre-mixed and then poured out.

  Conventionally, liquids such as adhesives, paints, and drugs are stored separately (stored in separate containers) until they are used, and only when mixing is started a plurality of liquids are mixed. Are widely used as they are ready for use. For example, in Patent Document 1, a main ingredient component containing a hydroxyl group-containing resin and a rust-preventive pigment composition and a curing agent component containing a polyisocyanate compound are stored in separate containers for a paint, before coating. Two-component polyurethane coating compositions have been proposed for use in admixture. As described above, in the case of the two-component type paint, a curing reaction occurs by mixing the main component paint and the curing agent immediately before coating, and a firm coating can be formed by firmly setting.

  Such two-component paints, etc., are stored in separate containers (cans, tube containers, etc.), and at the time of use they are taken out from both in appropriate quantities, mixed and stirred, but it takes time and effort At the same time, there have been various problems such as soiling the surroundings at the time of mixing and adhesion to fingers.

  Also, in the case of a sealing material or adhesive (eg, instant adhesive) made of two-component silicone, etc., silicone and the like react with water in the air and cure, so curing occurs during mixing. As a result, the two solutions can not be mixed sufficiently uniformly, which may cause unevenness in quality.

  Therefore, an object of the present invention is to develop a container for containing a conventional two-liquid mixture type adhesive, a paint and the like in order to solve the above-mentioned problems, and in particular, a plurality of different contents are They can be stored independently in a single container (bag) without being mixed until they are used, while they can be stored independently even with a weak force such as fingers when using them. It is about proposing about the multi-liquid filling bag which can be mixed simply and quickly uniformly.

As a result of earnest studies to achieve the above object, the present inventors have conceived of the present invention according to the summary constitution described below.
That is, the present invention comprises a bag main body which is partitioned into a plurality of storage chambers by at least one weak seal partition wall and is capable of storing different kinds of contents independently in each of the storage chambers, the weak seal partition A multi-liquid filled bag in which the contents in each storage chamber are premixed by mutually connecting the storage chambers by peeling off part or all of a wall,
The bag body has a joint formed by folding back one laminated film or laminating two laminated films and heat-sealing the superposed edges.
The weak seal partition wall is formed by heat-sealing the two stacked films which overlap each other, and is formed by folding the bag body into at least two in a direction intersecting the weak seal partition wall, and The bag body is characterized by being exfoliated by applying an external force to the bag body in the folded state.

In the multi-liquid filled bag of the present invention,
(1) The weak seal partition wall has a bonding strength which is easier to peel than the bonding portion of the bag body,
(2) The weak seal partition wall has a width of at least a portion of 0.01 mm or more and less than 1.0 mm,
Is a more preferable solution.

  According to the multi-liquid filling bag of the present invention, a plurality of different contents are independently accommodated by the weak seal partition wall before use, and the weak seal partition wall is small by the finger or the like. Since the contents can be premixed in the bag and uniformly mixed by being exfoliated by force, it is possible to always provide a mixture of the same quality. In addition, according to the multi-liquid filling bag of the present invention, it is possible to mix and stir a plurality of types of contents in the bag only by the pressing force by the finger or the like at the start of use, thereby reducing the number of containers. It is possible not only to simplify the mixing operation but also to prevent the contamination of the surroundings.

  Moreover, in the present invention, the bag main body is folded in the direction intersecting with the weak seal partition wall, and at least a part is separated by applying an external force to the bag main body in the folded state. As long as the bag body is held flat, even if an unexpected pressing force is applied from the outside, the weak seal partition wall does not peel off, and it is erroneous before the start of use such as the distribution process of goods, etc. There is no risk of mixing multiple contents.

  This is because, when the bag body is folded so as to intersect the weak seal partition wall, the thickness is doubled when flat, and the inside of the bag body is partitioned by the weak seal partition wall, In the folded state, for example, a bag body provided with one weak seal partition wall to form two storage chambers is divided into four compartments in the bag. Therefore, when an external force is applied to the bag body in the folded state, the pressed content increases the force applied to the weak seal partition wall (which is four times as large as when it is flat), and the weak seal partition wall easily by a small pressing force. Can be peeled off.

It is a top view which shows other embodiment of the multi-liquid filling bag of this invention.

Hereinafter, embodiments of the present invention will be described based on the drawings.
FIG. 1 is a view showing an embodiment of a multi-liquid filled bag according to the present invention.

  In the multi-liquid filling bag 1 shown in FIG. 1, for example, after a single laminated film including a base film layer and a sealant layer is half-folded at the center position in the width direction, the overlapping laminated films are heated longitudinally and vertically. As shown in the front view of FIG. 1 (b), the housing space 5 is sealed with the housing space 5 enclosed by the vertical seal portion 2, the upper horizontal seal portion 3 and the lower horizontal seal portion 4 by sealing. The two weakly-sealed partition walls 6 divide the two storage chambers 7a and 7b, and the storage chambers 7a and 7b are respectively filled with contents α and β of different types. The contents α and β can be various liquids such as liquid and viscous.

  In the present embodiment, the weak seal partition wall 6 of 1 is provided in the storage space 5 to divide the two storage chambers 7a and 7b. However, the present invention is not limited to this. A plurality of storage chambers may be provided to form a compartment.

  Moreover, in FIG. 1, although the weak seal partition wall 6 is provided in the direction parallel to the vertical seal part 2, it is not limited to this, accommodation, such as a direction parallel to the upper and lower horizontal seal parts 4, etc. As long as the space 5 can be divided into a plurality of rooms, it may be provided in any direction.

  In mixing the content α in the storage chamber 7a and the content β in the storage chamber 7b, first, the multi-liquid filled bag 1 is folded in two at a folding position 8 shown by a dotted line, for example, in the direction shown by the arrow in the figure. A plan view of the multi-liquid filled bag 1 in the folded state is shown in FIG. 2 (a), and a view of the folded state as viewed from the side is shown in FIG. 2 (b).

  In addition, in order to indicate the folding position 8, it is preferable to display the folding line in advance by printing or the like on the laminated film. In addition, the folding position 8 may be a position intersecting the weak seal partition wall 6, and as shown in FIG. 1, in the direction orthogonal to the weak seal partition wall 6, obliquely with respect to the weak seal partition wall 6 It can be in the crossing direction or the like. In addition, in the case of a large-volume multi-liquid-filled bag 1, it is preferable that a plurality of folding positions 8 be provided.

  The weak seal partition wall 6 can be formed by a peelable weak seal portion formed by bonding two overlapping laminated films to each other by a conventionally known method such as heat sealing. The weak seal portion formed in this way has a bonding strength of 30 to 70% of the vertical seal portion 2 and the upper and lower horizontal seal portions 3 and 4 regardless of the form, that is, it peels easily. A heat seal portion, which can be peeled off by the force of the pressurized contents α and β, for example, when the storage chambers 7a and 7b are pressed in the folded state with a finger.

  As is clear from FIGS. 1 (b) and 2 (b), the multi-liquid filled bag 1 is folded in two at the folding position 8 to have a thickness of about 2 in the flat posture shown in FIG. 1 (b). It will be doubled. In addition, since the multi-liquid filling bag 1 is originally divided into two storage chambers 7a and 7b by the weak seal partition wall 6, the inside of the bag is divided into four spaces by folding it into two as described above. It will be

  Therefore, in use, if the storage chamber 7a side of the multi-liquid filled bag 1 in the folded position is pressed with fingers as shown in FIG. 3 (a), the multi-liquid filled bag 1 in flat position with the same force (see FIG. When the liquid-filled bag 1) is pressed, about four times the force (pressure by the pressurized content) acts on the weak seal partition wall 6, and about one-fourth of the flat in FIG. The weak seal partition wall 6 can be easily peeled off with a small force.

  In other words, in the flat posture (FIG. 1) of the multi-liquid filled bag 1, the weak seal partition wall 6 has a tear strength when pressed in a posture folded in a direction crossing the weak seal partition wall 6 as described above. Because the strength is about four times that of the above, even when an unintended external force is applied when transported in a flat posture, etc., the weak seal partition wall 6 does not peel off easily, and the contents α, There is no risk that β will be mixed unexpectedly.

The load (peel load (F)) required to peel the weak seal partition wall 6 can be calculated according to the following equation, and the thickness (Z) of the multi-liquid filled bag 1 is increased by It is understood that the peeling load (F) of the weak seal partition wall 6 is reduced.
F = T × X × Y / Z
F: Peeling load of weak seal partition wall (kg)
T: Bonding force of weak seal partition wall (kg / cm)
X: Longitudinal length of multi-packed bag (cm)
Y: Horizontal length of multi-packed bag (cm)
Z: Thickness (in the pressed posture) of multi-packed bags (cm)
The peeling load of the weak seal partition wall 6 is preferably 5 kg or more, preferably in the range of 5 to 25 kg, and by setting it in this range, even when transporting or working in the flat posture shown in FIG. It is possible to prevent peeling of the weak seal partition wall 6 without affecting the other vertical seal portion 2 and the upper and lower horizontal seal portions 3 and 4 while preventing peeling of the weak seal partition wall 6. .

  When the storage chamber 7a is pressed in a folded state of the multi-liquid filling bag 1, the weak seal partition wall 6 is easily peeled off, and the content α in the storage chamber 7a is stored in the storage chamber 7b as shown in FIG. The contents .beta. And the contents .beta. Are mixed in a short time along with the injection. When the viscosity of the contents α and the contents β is high, uniform mixing can be advanced by holding the storage space 5 from the outside with fingers after mixing as described above. Moreover, if different colors are added to the contents α and β, or a pigment or the like that changes color due to mixing is added, visual recognition of the mixed state is easy and uniform mixing can be ensured.

  As described above, in the multi-liquid filling bag 1 of the present invention, the contents can be poured out after uniformly mixing the contents in advance in the bag, so that the contents may be caused by moisture in the air such as silicone. Even if it has the property of curing, there is no risk of curing during mixing, and it is possible to always supply a mixture having a certain quality.

  The contents (α + β) mixed as described above are, for example, through notches or the like provided on the outer peripheral seal portion (vertical seal portion 2, upper and lower horizontal seal portions 3 and 4) of the multi-liquid filling bag 1 Open and pour out, as shown in another embodiment of FIG. 4, the pouring passage 9 is provided on the folded side of the laminated plastic film of the upper horizontal seal portion 3, and the upper horizontal seal portion 3 upper end edge The container is unsealed and poured out by tearing along the tear guiding wire 10 toward the side edge of the pouring passage 9 or a pouring nozzle made of laminated plastic film is provided so as to protrude from the outer peripheral seal portion. May be

  The folding position 8 may be provided at a plurality of locations as described above, and in this case, the weak seal partition wall 6 is set to such a high bonding strength that peeling can be performed by multiple folding at the folding position 8. (With the increase in thickness of the multi-liquid-filled bag 1 due to folding, the pressing force by the content on the weak seal partition wall 6 also becomes high, so the bonding strength of the weak seal partition wall 6 can be increased. ), Unexpected peeling off at the time of handling etc. can be prevented more effectively.

  When the weak seal partition wall 6 is formed by a joint portion (heat seal portion), the joint strength may be controlled, for example, by adjusting the pressure and temperature at the time of heat seal, and the joint width may be devised Can be controlled by That is, in the case of adjusting with the bonding width, it is excellent in that it is not necessary to adjust fine pressure and temperature at the time of heat sealing. In this case, the bonding width of the weak seal partition wall 6 is at least partially 0. It is preferable to set it as 01 mm or more and less than 1.0 mm. By setting it in the above-mentioned range, it becomes easy to peel off with a small pressing force, and the contents (α, β) are sprayed at high speed along with the peeling, and both are uniformly mixed and stirred rapidly. The reason is that
