[0008] The paper serving as the base material may be any paperboard having tear resistance and a certain degree of rigidity, but preferably has printability like paperboard used in general cartons. Instead of paper alone, a plastic film, metal foil, or the like may be laminated on the front or back surface of the paper.
Printing is performed on the carton surface by a normal printing technique such as offset printing or gravure printing, and then a blank is formed in a punching process.

FIG. 3 is an exploded view of a blank showing the carton body 1 of the simultaneous bag-opening carton B for storing a plurality of bags according to the present invention. The blank 10 has a side surface 11, a front surface 12, a side surface 13, a rear surface 14, and a glue allowance piece 15, which are sequentially provided via respective broken lines. In addition, below the side surface 11, the front surface 12, the side surface 13, and the rear surface 14, the bottom horizontal surface 16, the bottom upper surface 17, the bottom horizontal surface 18, and the bottom lower surface 19 are provided via respective broken lines.

The shape of the bag 2 is preferably a gusset pillow type bag as shown in FIG. 4B which can be efficiently stored in the carton body 1. As shown in FIG. 4A, the joint portion 3 includes an outer piece 4 and an inner piece 5.
After sealing the back, as shown in FIG. 4B, the position of the palm portion 3 is set not to the center but to the edge so that it does not protrude from the upper surface of the bag body when bent toward the inner piece 5 side. . Then, as shown in FIG. 4C, a shape in which the end 4a of the outer piece 4 is turned outward is preferable. By inverting the end 4a of the outer piece 4 outward, opening can be easily performed. When the end 4a of the outer piece 4 is turned outward, the outer piece 4
And a shape in which a notch 6 is formed in the end 4a of the outer piece 4 and the end 4a between the notches 6 is inverted, as shown in FIG. The latter is more preferred. Further, it is preferable that the folded inner piece 5 and the bag body are partially adhered, or in the seal on both sides after the contents are filled, the folded joint part 3 and the bag body are adhered at the seal part 8. .

In the bag 2 of the carton B of the present invention, in order to open the gusset pillow-type bag, a method of tearing by providing a pair of notches 6 on the outer piece 4 of the joint part 3 is adopted. It has a shape to have the function of being opened at the same time as it is pulled out from 1. In other words, the bag 2 can be opened starting from the portion where the outer piece 4 of the palm part 3 is adhered to the carton body 1. The notch 6 is preferably deeper from the end of the outer piece 4 toward the back seal, and when turning the outer piece 4 outward, it is necessary to at least make the notch 6 deeper than the fold at which the outer piece 4 is turned.

In addition, a pair of notches 6 are provided at the end of the joint portion 3 of the bag 2 of the bag simultaneous opening carton B of the present invention, and at least the back seal 7 is weakly sealed.
A desirable weak seal in the present invention is a method in which an easy-opening resin is laminated on the entire back surface of the base film. However, in general, a weak seal using the easy-opening resin has a peel resistance for opening. Is too strong. In the future, if the improvement of the easy-opening resin, for example, the easy-opening by blending of the heat-seal inhibiting component can be realized, 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 to apply a solution-type or emulsion-type adhesive to the entire inner surface of the base film or the position at which the back seal is to be performed. This is to apply it to a site in consideration of the displacement.

As a method of applying the adhesive partially, a gravure plate, a relief plate made of rubber or resin, or the like can be used. However, in the case of the entire surface application, in addition to the above-described method, the 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, an acrylic resin, nitrocellulose, or chlorinated polypropylene, and an emulsion type or a solution type of these resins is used.

[0014] It is also possible to use a cold sealant as a weak seal. The cold seal has a coating surface that is not tacky, but can be bonded by strongly pressing the coating surfaces together, and does not require heating at this time. The main component of the cold sealant is synthetic rubber, natural rubber, or acrylic resin. In the case of the partial coating method of the sealant, it is economical because there is no need to apply an adhesive to the non-adhered portion.

The weak seal according to the present invention has an easy-opening property while maintaining the moisture-proof property for preserving the contents and the strength which does not impair the scent-retaining property. Care must be taken when applying to contents and the like.

In order to ensure that the film is torn in the tearing direction when the film is opened from the notch 6, the material composition is set to include a transversely uniaxially stretched film. In the present invention, it is desirable that the transverse uniaxially stretched film be present in the packaging material composition to impart easy tearing in the lateral direction, but in addition to the transverse uniaxially stretched film, a film exhibiting other properties,
For example, even if biaxially stretched films of polypropylene, polyester, polyamide, etc. are laminated, the tearability of the bag in the lateral direction is not impaired. Providing a coating of resin or the like or a deposited layer of aluminum or silicon oxide for improving gas barrier properties does not hinder the practice of the present invention.

Next, the carton main body 1 and the joint portion 3 of the bag
Are partially adhered, but in the present invention, FIG.
As shown in the sectional view of FIG.
And the end of the outer piece 4 and the front 12 of the carton body 1

a and the back surface of the front surface 12 of the carton body 1 are adhered.
The bonding position is a portion on the front side when the bag 2 is pulled out from the carton body 1. The strength of the bonding, the bonding pattern or the area may be acceptable as long as the bag 2 is pulled out. That is, when pulling out the bag 2 from the carton main body 1, it is only necessary that the joint portion 3 of the bag 2 can be easily opened. Therefore, the adhesive force between the front surface 12 of the carton body 1 and the outer piece 4 of the joint portion 3 of the bag 2 is equal to the back seal portion 7 of the joint portion 3 of the bag 2 and the bag 2.
It is necessary that the adhesive strength is larger.

In the bag simultaneous opening carton B in which a plurality of bags 2 are stored, a plurality of bags 2 are stored in the carton body 1 in a state of being arranged in parallel. A partition 9 may be provided on the front surface 12 or the rear surface 14 of the carton body 1 for storage in an aligned state. This partition 9
As shown in FIG. 2, there is a method of laying or fixing a wavy bottom paper on the bottom surface, or a method of attaching a convex member between the bags 2 and the like. By providing the partition 9, the bag 2 can be easily pulled out from the carton body 1.
