Description

  The present invention relates to a plastic film bag for stuffing flour, coffee, cocoa, detergent powder or the like.

Conventionally, as a bag of this type, as shown in FIG. 8 , the exterior films 1 are sealed together by sealing with the seal portions 2 and 3 on both sides and the upper end, and at the cutting position C below the upper end seal portion 3. 1 is used which is opened when cut and can be resealed when the fastener 4 provided on the inner side of the exterior film 1 is engaged therewith.

  However, in the bag as described above, when opened, only a large opening is formed at the upper end, so it is good to sprinkle the powder of the contents in large quantities with a spoon, I couldn't do it and I felt inconvenienced.

  In view of this, the present invention is intended to provide a bag in which the required amount of powder of the contents can be easily taken out.

In order to solve the above-described problems, the present invention is to seal the exterior films by bonding them with the seal portions on both sides and the upper end, and setting the lower side of the seal portion on the upper end as a cutting position for opening, below the inside of the exterior film. In a bag provided with a resealing fastener to be engaged, an intermediate film having a small opening is folded between the outer films, and one side of the intermediate film is bonded to one inner surface of the outer film. At the lower side of the cutting position, the side film is not bonded to the other inner surface of the exterior film, and a fastener that engages with the re-sealing fastener is provided on both sides of the intermediate film, and the exterior film is cut and opened at the cutting position. and, to that to switch the aperture size depending is meshed fasteners intermediate film in any of the exterior film side of the fastener A.

  As described above, if the opening size of the bag can be switched, it can be opened as usual, and the powder of the contents can be squeezed in large quantities from the opening with a spoon etc., and the large opening is closed. It is also possible to open a small opening and tilt the bag to squeeze out a small amount of powder from the small opening.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The bag according to the first embodiment shown in FIG. 1 is a standing pouch for storing a powder product, and the exterior films 1 are sealed by adhering the exterior films 1 with the seal portions 2 and 3 on both sides and the upper end. Is a cutting position C for opening, and a re-sealing fastener 4 that engages inside the exterior film 1 is provided below the cutting position C.

  As shown in FIG. 4, an intermediate film 5, which is one extension portion of the exterior film 1, is folded between the exterior films 1, and a plurality of small openings 6 are formed in the intermediate film 5. ing.

  One side of the intermediate film 5 is bonded to one inner surface of the exterior film 1, and a switching fastener 7 that meshes with the resealing fastener 4 is provided on both sides of the intermediate film 5. These fasteners 4 and 7 are a pair of a ridge member and a groove member.

  In this embodiment, the fastener 4 on the one exterior film 1 side is provided on the intermediate film 5, but the intermediate film 5 is a separate member from the exterior film 1, and the adhesive portion between the intermediate film 5 and the exterior film 1 is provided. The fastener 4 may be provided directly on one exterior film 1 by shortening downward.

  In the bag as described above, the exterior film 1 is cut and opened at the cutting position C, and the intermediate film 5 is folded in half, as shown in FIGS. When the other side fastener 7 is separated from the opposite fastener 4, a large opening portion 8 is formed as in the prior art, and a spoon is inserted through the opening portion 8 so that a large amount of powder of the contents can be obtained. Can crawl out.

  On the other hand, as shown in FIGS. 3 and 6, the fastener 7 on one side of the intermediate film 5 is separated from the opposing fastener 4, the intermediate film 5 is passed in the direction of the other exterior film 1, When the fastener 7 is engaged with the opposing fastener 4, the bag can be tilted, and the powder of the contents can be dispensed little by little from the plurality of small openings 6.

  Further, as shown in FIG. 7, when the fasteners 7 on both sides of the intermediate film 5 are engaged with the respective opposing fasteners 4, the cut portion at the upper end of the bag is completely closed, and a resealed state can be obtained. Intrusion of dust into the bag and moisture of the powder of the contents can be prevented.
