FIG. 3 is an explanatory view for creating the bag 2 of the bag simultaneous opening carton A according to the present invention. As the shape of the bag 2, a gusset pillow type bag as shown in the figure that can be efficiently stored in the carton body 1 is suitable. As shown in FIG. 3A, the palm portion 3 includes an outer piece 4 and an inner piece 5, and after the palm portion 3 is back-sealed, as shown in FIG. Rather, it is set to the end so that it does not protrude from the upper surface of the bag body when bent toward the inner piece 5 side. And as shown to FIG. 3-c, the shape which reverses the edge part 4a of the outer piece 4 to an outer side is preferable. By opening the end 4a of the outer piece 4 to the outside, the opening can be easily performed. When the end 4a of the outer piece 4 is reversed outward, the shape of the entire end 4a of the outer piece 4 is reversed, and a notch 6 is provided in the end 4a of the outer piece 4 as shown in FIG. There is a shape in which the end portion 4a between the notches 6 is formed and the latter is more preferable. Furthermore, it is preferable that the folded inner piece 5 and the bag body are partially bonded, or the folded palm portion 3 and the bag body are bonded at the seal portion 8 in the seals on both sides after filling the contents. .
[0014]
In the bag 2 of the bag simultaneous opening carton A of the present invention, in order to open the gusset pillow type bag, a pair of notches 6 are provided on the outer piece 4 of the palm portion 3 to tear the bag, and the bag is taken out from the carton body 1. At the same time, it is shaped to give it the function of being opened. That is, the bag 2 can be opened from the portion where the outer piece 4 of the palm portion 3 is bonded to the carton body 1. The notch 6 is preferably deeper from the end of the outer piece 4 toward the back seal. When the outer piece 4 is reversed outward, it is necessary to be deeper than at least the fold line that reverses the outer piece 4.
[0015]
A pair of notches 6 are provided at the end of the palm portion 3 of the bag 2 of the bag simultaneous opening carton A of the present invention, and at least the back seal portion 7 is bonded weakly. The weak seal desirable in the present invention may be formed by laminating an easily-openable resin on the entire back surface of the base film, but in general, a weak seal with an easily-openable resin has a resistance to peeling for opening. Is too strong. In the future, if the easy-opening resin can be improved, for example, easy-opening can be realized by blending heat seal inhibiting components, it can be used as the weak seal of the present invention. A more preferable method for making the back seal portion 7 in the present invention a weak seal is that a solution-type or emulsion-type adhesive is sealed on the entire inner surface of the base film or a position where the back seal is performed. It is to apply to the part in consideration of the displacement.
[0016]
As a method for partial application of the adhesive, a gravure plate, a relief plate made of rubber or resin, or the like can be used. However, in the case of whole surface application, in addition to the above-described method, application may be performed by roll coating, air knife coating, or the like. The adhesive component of the type to be applied is an ethylene-vinyl acetate copolymer, acrylic resin, nitrocellulose, chlorinated polypropylene, and emulsion type or solution type of these resins are used.
[0017]
It is also possible to use a cold sealant as a weak seal. In the cold seal, the coated surfaces are not sticky, but can be bonded by strongly pressing the coated surfaces, and heating is not required at this time. Synthetic rubber, natural rubber or acrylic resin is used as the main component of the cold sealant. In the case of the partial coating method of the sealing agent, it is economical because it is not necessary to apply an adhesive to the non-adhesive portion.
[0018]
The weak seal of the present invention has easy-opening properties while maintaining strength that does not hinder moisture-proofing or fragrance retention for the preservation of contents, and the contents are heavy because they are weakly sealed. Care must be taken when applying to this.
[0019]
Moreover, it sets so that a laterally uniaxially stretched film may be included in a material structure so that a film may be surely torn in the tearing direction when opening from the notch 6. In the present invention, it is desirable that a transversely uniaxially stretched film is present in the packaging material structure to impart easy tearability in the transverse direction, but in addition to the transversely uniaxially stretched film, a film exhibiting other characteristics, such as polypropylene Even when biaxially stretched films such as polyester and polyamide are laminated, the tearability in the lateral direction of the bag is not impaired, and these films, including laterally uniaxially stretched films, have moisture resistance and gas barrier properties. In order to improve the above, provision of a coating of resin or the like or a vapor deposition layer of aluminum or silicon oxide does not cause any trouble in the implementation of the present invention.
