Description

The present invention relates to a zipper film bag bag used for opening a zippered film bag from a sealed state.

  In recent years, many types of bags have been provided with a zipper that can seal the inside of the bag to prevent drying of the food during storage and, conversely, moisture, on packaging bags for food such as confectionery and seasonings. It has come to be used. This film bag 51 with a zipper (hereinafter referred to as a film bag 51) is shown in FIGS. As shown in FIG. 6, a rectangular film material is folded back approximately at the center in the longitudinal direction to form a lower end 51 </ b> A, the left and right side edges 51 </ b> B and 51 </ b> B are abutted and fixed by means such as heat welding, The other side film 53 is formed in a bag shape with the upper end opened. A zipper 54 of a type that engages by pressing is provided on the inner surfaces near the upper ends 52A, 53A of the films 52, 53, and the upper ends 52A, 53A of the films 52, 53 are fixed by means such as heat welding. The sealing part 51C of the film bag 51 is provided.

When opening the film bag 51, the upper end 52A, 53A side is conventionally cut from the zipper 54 of the film bag 51 with a two-blade scissors. The cutting edges 52B and 53B are linearly overlapped (see FIG. 7). And since the film bag 51 is formed of a material such as rigid polypropylene considering the storage stability of food or the like and the strength against repeated opening and closing operations, the cut edges 52B and 53B overlap closely. However, there is a problem that it is not easy to open the cutting edges 52B and 53B for an elderly person, a child or a person with a fingertip.

  However, a special bag for opening such a film bag 51 is not known. In addition, as a cocoon with limited use from the past, for example, a cocoon made up of three blades by combining blades with different blade shapes so that the shear line is different, and made up of three blades to cut shellfish shells In addition, there is a scissors configured with three blades so that one of the blades is opened widely (Patent Document 1).

JP 2002-58884 A

  As described above, the three-blade scissors are known, but no scissors have been proposed in which the film bag 51 is cut so that the zipper can be easily opened. Further, the shape of the blade differs depending on the application, the meshing state, etc., and even if the three-blade blade with different uses is diverted, the films 52 and 53 of the sealed film bag 51 have different cutting edges. Therefore, there is a problem that it is practically difficult to cut each of the cutting edges and to cut the cutting edges with good finish.

  The present invention has been made in view of the above-mentioned unsolved problems of the prior art. The film bag 51 can be cut and opened in the same manner as a two-blade scissors, and the handling is excellent. An object of the present invention is to provide a zippered film bag bag that can be easily opened by an elderly person, a child, or a person with a fingertip difficulty.

  The means of the present invention configured to solve the above-described problem is that one side in the longitudinal direction is a handle portion, the other side is a blade portion through the handle portion, and a cutting blade is formed on the inner edge of the blade portion. A rod body that is connected to a pair of housings so as to be pivotable by a support shaft, a long hole into which the support shaft is inserted so as to be displaceable in the front-rear direction, and a receptacle that intersects the cutting blades of the housings on both side edges. An intermediate blade having a blade and sandwiched between the pair of housings in a state where the support shaft is inserted into the elongated hole, and a lower end side is pin-coupled to a lower end side of the intermediate blade body, and a tip side Is composed of a pair of interlocking arms that are pin-coupled to the handle of each housing.

  The intermediate blade body may be set to a thickness of about 2 to 4 mm.

The pair of housings, the intermediate blade body, and the pair of interlocking arms may form a quadrilateral link, and the pair of housings may intersect with the intermediate blade body while being displaced in a linear direction.

Since the present invention is configured as described above, the following effects can be obtained.
(1) Since the one-side film and the other-side film are cut at a position closer to the tip side than the zipper of the zippered film bag so that there is a gap portion corresponding to the thickness of the intermediate blade, the opener puts the fingertip on the gap portion By inserting, the zipper of the film bag can be opened easily and reliably.
(2) The thickness of the intermediate blade is set to about 2 to 4 mm, and the misalignment is surely present on both cut edges of the one side film and the other side film. Can also insert a fingertip easily and can open it reliably.
(3) Since the quadrilateral link is constituted by the pair of housings, the intermediate blade body and the pair of interlocking arms, the pair of housings intersect with the intermediate blade body while being displaced in the linear direction. Since the film is cut not by shearing but by cutting, the cutting resistance is small, and the film can be easily cut without applying a large force.
