Japanese Unexamined Patent Publication No. 2004-250041 JP-A-2010-132758

When a two-agent liquid cleaning agent consisting of an agent A and an agent B is used as a two-agent solid cleaning agent from the viewpoint of handleability, for example, a powdered agent A containing an oxygen-based bleach and a carbonate. When the powdered agent B containing salt is stored in a conventional film packaging bag having two storage portions, gas may be generated from the agent A during storage. For this purpose, it is conceivable to use a thick and strong film material so that the storage portion of the agent A does not swell or burst remarkably, or to open a ventilation hole in the storage portion of the agent A.

However, even if a thick and strong film material is used, a ventilation hole is provided in the storage portion of the A agent, and an opening start portion such as a notch is provided in the seal portion or the partition seal portion on the side of the storage portion, A If the agent storage portion and the agent B storage portion are to be opened at the same time, powder may be scattered from the storage portion when the opened piece is torn off from the storage portion.

In response to such a problem of the prior art, it is a package in which two kinds of solid contents are separately stored in two storage portions, and one of the contents is like an oxygen-based bleach and emits gas during storage. It is a gas-generating composition having a property of being easily generated, and when a vent hole capable of discharging gas is provided in the storage portion, the two storage portions can be reliably opened by a single opening operation by tearing, and at the time of opening. The challenge is to be able to prevent the contents from scattering.

The present inventor is a package in which the first storage portion and the second storage portion are continuous with the partition seal portion sandwiched between them, the gas-generating composition is stored in the first storage portion, and the gas is vented in the first storage portion. When a hole is provided, an opening start portion of the first storage portion such as a notch is formed in the seal portion on the side of the first storage portion facing the partition seal portion, and the opening start of the first storage portion of the partition seal portion is started. When the opening start portion of the second storage portion is formed at a position corresponding to the portion, the tear from the opening start portion of the first storage portion extends to the opening start portion of the second storage portion, and the second storage portion to be opened later. In this case, if the contents of the second storage section are at least tablet-shaped instead of powder, the second storage section can be easily opened even when the opened piece of the second storage section is torn off from the second storage section. It is possible to prevent the contents of the part from scattering, and even if the opened piece of the second storage part is incompletely torn off from the second storage part and the opened piece remains attached to the second storage part. The present invention was completed with the idea that the entire amount of the contents stored in the second storage unit can be reliably taken out.

That is, in the present invention, the first storage portion and the second storage portion formed of the film are continuous with the partition seal portion interposed therebetween, and the solid gas-generating composition is stored in the first storage portion, and the second storage portion is stored. A packaging body in which a tablet-like composition is stored, which has an opening start portion of the first storage portion at a seal portion on the side side of the first storage portion facing the partition seal portion, and the first storage portion. Provided is a package having an opening start portion of a second storage portion in a region where the planned opening direction by the opening start portion of the portion intersects with a partition seal portion, and a gas vent hole in the first storage portion.

Further, in the present invention, the first storage portion and the second storage portion are continuous with the partition seal portion interposed therebetween, the solid gas-generating composition is stored in the first storage portion, and the tablet-like composition is stored in the second storage portion. A packaging bag for storing gas, in which the first storage portion and the second storage portion each have an opening for storing the contents, and a seal on the side of the first storage portion facing the partition seal portion. The opening portion of the first storage portion is provided in the portion, and the opening start portion of the second storage portion is provided in the area where the planned opening direction by the opening start portion of the first storage portion and the partition seal portion intersect. 1 Provide a packaging bag having a degassing hole in the storage portion.

According to the package of the present invention, even if gas is generated from the gas-generating composition stored in the first storage portion during storage of the package, the gas is removed from the gas vent hole of the first storage portion. Can be done.

Further, since the opening start portion of the second storage portion is located on the extension of the opening start portion of the first storage portion in the planned opening direction of the first storage portion, the first storage portion is torn from the opening start portion of the first storage portion. Then, the tear extends to the opening start portion of the second storage portion, and the second storage portion is torn, so that the first storage portion and the second storage portion can be opened with a single opening operation.

Further, the tearing of the first storage portion extends to the opening start portion of the second storage portion, and the second storage portion is torn from the opening start portion of the second storage portion, so that the tearing of the second storage portion becomes smooth. It is prevented that the contents are scattered from the first storage portion and the second storage portion.

Further, since the contents of the second storage portion are in the shape of a tablet, the contents are prevented from being scattered from the second storage portion, and the second storage portion is tentatively torn incompletely. 2 Even if the opened piece remains in the storage portion, the entire contents of the second storage portion can be easily and surely taken out.

In particular, in this package, a mode in which a powdered oxygen-based bleach is stored as a gas-generating composition in the first storage portion and a tablet-shaped carbonate-containing foaming composition is stored in the second storage portion is the first. 2 Since the tablet-like carbonate-containing foaming composition in the storage portion acts as a pH adjuster for enhancing the bleaching effect of the oxygen-based bleach in the first storage portion and as a foaming agent for which foaming is sustained during bleaching. It is a package of a two-agent cleaning agent that has a high bleaching effect and visually shows that the bleaching effect is sustained by foaming. Moreover, since the oxygen-based bleach and the carbonate-containing effervescent composition can be opened with a single opening operation, not only one of the oxygen-based bleach and the carbonate-containing effervescent composition, but both of them are used at the same time. The user of the cleaning agent can be guided so as to.

Further, according to the packaging bag of the present invention, the packaging body of the present invention is easily facilitated by putting the gas-generating composition in the first storage portion, putting the tablet-like composition in the second storage portion, and sealing the packaging bag. Can be obtained.

(overall structure)
FIG. 1 is a plan view of a package 1A according to an embodiment of the present invention.
This package 1A has a partition seal portion 2A at a substantially central portion of a film flat bag having a four-way seal, and the first storage portion 3 and the second storage portion 4 are continuously arranged side by side with the partition seal portion 2A interposed therebetween. The solid gas-generating composition 20 is stored in the first storage unit 3, and one or more tablet-shaped compositions 21 are stored in the second storage unit 4.

(Opening start part of the first storage part)
A V-shaped notch is formed as an opening start portion 5 of the first storage portion 3 in the seal portion 2B on the side side of the first storage portion 3 facing the partition seal portion 2A. In the present invention, the opening start portion 5 of the first storage portion is not limited to the V-shaped notch, and an I-shaped notch and a U-shaped notch may be formed, and "magic cut" (registered trademark) may be formed. A portion that can be easily opened may be formed by providing a large number of fine holes such as the above.

(Opening start part of the second storage part)
The opening start portion 5 of the first storage portion 3 causes the first storage portion 3 to be torn from the opening start portion 5 substantially parallel to the upper side or the lower side of the package 1A, which is indicated by an arrow X in this case. An opening start portion 6 of the second storage portion 4 is formed in a region where the planned opening direction and the partition seal portion 2A intersect. In the package 1A of the present embodiment, the opening start portion 6 of the second storage portion 4 is formed with a region in which a plurality of perforated cuts 7 extending substantially parallel to the planned opening direction X are arranged in parallel. As the perforated cut 7, the cut portion of the perforation penetrates the film, the length L1 of the cut portion is 0.5 to 2.0 mm, and the length L2 of the uncut portion is 0.5 to 2. 0 mm, the distance L3 between the perforated cuts 7 in parallel is 0.5 to 2.0 mm, the number of perforated cuts 7 in parallel is 8 to 50, or the parallel region of the perforated cuts 7 It is preferable that the width L4 is 3.0 to 15 mm from the viewpoint of easily opening the second storage portion. On the other hand, as the opening start portion 6 of the second storage portion 4, as shown in the package 1B shown in FIG. 2, a Y-shaped notch with the upper end of the Y-shape directed toward the opening start portion 5 of the first storage portion 3 or An X-shaped notch may be provided so that the X-shaped> -shaped portion faces the opening start portion 5 of the first storage portion 3. When the first storage part 3 is torn from the opening start part 5 of the first storage part 3 while being slightly displaced up and down, the second storage part 4 in the partition seal part 2A before tearing the second storage part 4 Since the deviation in the tearing direction in the first storage portion 3 can be corrected in a direction substantially parallel to the planned opening direction X at the notch portion of the opening start portion 6, and the individual notch lengths in the opening start portion 6 can be shortened. A perforated cut is preferable as the opening start portion 6 of the second storage portion 4. By making the perforated cut, it is possible to prevent the notch of the opening start portion 6 from being unnecessarily caught in the manufacturing process of the package 1A and the transporting process of the manufactured package.

Regardless of whether the opening start portion 6 of the second storage portion 4 is any of the opening start portions 6 of the packaging bodies 1A and 1B described above, the packaging bodies 1A and 1B are torn from the opening start portion 5 of the first storage portion 3. First, the first storage portion 3 is torn and opened, and the tear reaches the opening start portion 6 of the second storage portion 4 provided in the partition seal portion 2A, whereby the tearing force is second-stored. It acts effectively on the tearing of the part 4, and the second storage part 4 is also torn. Therefore, both the first storage unit 3 and the second storage unit 4 are opened by one tearing operation, and are stored in the gas-generating composition 20 and the second storage unit 4 stored in the first storage unit 3. Both of the tablet-like compositions 21 can be taken out from the storage portions 3 and 4. In general, when the content of a film package is powder, it is necessary to tear the package from the notch and take care not to scatter the content when the torn pieces are torn from the packaging bag. However, in the packages 1A and 1B, the tearing progresses smoothly from the start of opening the first storage unit 3 to the completion of opening the second storage unit 4, so that the contents are less likely to scatter, and further, the second storage unit 4 Since the contents are tablet-shaped, there is no possibility that the contents will be scattered from the second storage portion 4 even if the first storage portion 3 to the second storage portion 4 are torn at once.

(Gas vent hole)
