The present invention relates to a packaging bag used for packaging vegetables, fruits and flowers such as eggplant, cucumber, spinach and the like.

Most of vegetables and fruits sold in supermarkets are packaged and sold in bags made of synthetic resin film such as polyethylene, and usually these packages are collected from producers and delivered to supermarkets, etc. Is done in the process.

These packings are carried out at facilities such as agricultural cooperatives in the production area, and are carried out by automatic packing machines at facilities with high handling volumes and by manual labor at facilities with low handling volumes.

When carrying out the packing work by hand, the packing efficiency differs remarkably according to the kinds of flowers and fruits. For example, eggplants, bell peppers, apples, persimmons, etc. are hard to put in the bag, because the surface does not slide well because they stick to the inner surface of the film. Adhesion is alleviated, but the work efficiency is significantly reduced.

In particular, in the case of a branch, the surface of the branches tends to be in close contact with the overall shape and moderate elasticity, and when the second and third bags are put in a bag, the surface of the branches is brought into close contact with the film, and the surfaces of the branches are brought into close contact with the surface of the first branch. It is easy to be in a state where the branch which I want to move does not move forward and backward.

As a countermeasure against this, the present applicant has devised a packaging aid that consists of a packaging bag supporting frame having a through hole through which a packaged object can pass, and a support for supporting an opening at one side of the through hole of the supporting frame in a substantially horizontal state. 9 is a perspective view showing the packaging aid 51. The packaging aid 51 is largely divided into a ring-shaped support frame 52, a support 53, and a die 54. As shown in FIG.

The support frame 52 is formed by ring-shaped plastic or stainless steel, and is supported by the strut 53 so that the support frame 52 is almost horizontal. The size of the through hole of the support frame 52 is such that some packaged objects such as branches can pass therethrough.

The die 54 is a leg 54a on the side of the support frame 52 of the four legs 54a to 54d so that the entire tool can be stably supported even when a biased load is applied when the assisting tool 51 is used. And 54b are made longer than the opposite legs 54c and 54d.

In order to wrap the branch N using the packaging aid 51, the assisting tool 51 is placed on a suitable work surface, and the bag H is first supported upward by the bottom as shown in Fig. 4 (a). It covers the frame 52. Next, several branches (N) are held in hand and placed at the bottom of the bag (H) at the same time, and then the branches (N) are pushed into the support frame (52) for each bag (Fig. 4 (b)). Accordingly, the bag H is pressed against the branch N so that the bottom portion is pressed into the lower portion of the support frame 52, and the bag H is inverted while the bag H is wrapped, and the inside of the support frame 52 together with the branch N is wrapped. It passes and falls to a work object (FIG. 4 (c)) In this way, by using the packaging aid 51, the bag H which bottomed up is covered with the support frame 52, and the bag H of It is possible to push the branch N into the support frame 52 from the top, and to insert the branch N into the bag H while reversing the bag H. Accordingly, in the steps of FIGS. 4A to 4C, the branches N and the bags H are simultaneously moved while being in contact with each other, and the branches N are smooth and the surface N is easily adhered to the bags H. Insertion into the bag H is smoothly performed, and packaging can be carried out efficiently.

By the way, the packaging bag (H) used in such a packaging is closed by heat-sealing the three sides of both sides and the bottom surface except the opening by a few mm from the outer edge, the information on the contents, production place, seller, etc. It is printed. Therefore, in order to bring the packaging bag H into the state as shown in FIG. 4 (a), it is necessary to cover the packaging bag H with the support frame 52 upside down, and this operation is performed using the packaging aid 51. It is a great deterrent to the efficiency of packaging work. Therefore, the problem to be solved by the present invention is to make it possible to use the packaging bag without inverting it, and to achieve higher efficiency of the packaging operation using the packaging aid.

In order to solve the above problems, the packaging bag of the present invention is a reversible packaging bag body having at least a printing portion formed of a transparent synthetic resin sheet, having an opening for inserting a product on the upper portion, and a joining portion of the circumferential edge joined by a blown seal. Characterized in that the back printed information on the inner side or the outer side of the sealing body.

Here, the reverse printing refers to a printing method in which the normal state is seen from the inside when the information such as the design printed on the encapsulation body is viewed from the encapsulation state, and the information is printed on the inner side of the encapsulation body in the manufacturing state. In some cases, information may be printed on the outer surface. In particular, when used for food packaging, it is preferable to print on the inner side of the bag body in a bag manufacturing state so that information is located on the outer side of the bag without contact between the food and the printing ink at the time of packaging. In addition, unlike the method of bonding the area by hot seal, the melted seal is connected to the edges of the synthetic resin sheet at the same time as the melted edge, so that the encapsulated state can be used regardless of front and back. .

In addition, in order to facilitate the reversal operation of the bag in the packaging operation using the packaging aid, a triangular cut portion formed by the melting seal can be formed on the bottom side of the sealing body.

In addition, if the front sheet and the rear sheet side constituting the encapsulated body protrudes to the upper side than the other side, it is possible to automate the operation of covering the packaging bag on the support frame.

In addition, the packaging bag in which the information is printed on the inner side in the bag manufacturing state prints the information on the surface of the sheet-like material made of transparent synthetic resin, and the portion that becomes the bottom of the packaging bag by folding the sheet-shaped object so that the side on which the information is printed is inside. It is possible to manufacture by almost the same process as in the prior art by using the manufacturing method of forming a portion, and the sheet-like article folded and superimposed by cutting the sheet-like seal to form a portion that becomes both edges of the packaging bag.

As described above, the sealing body is formed by the melting seal, and the back printing is performed on the sealing body so that the packaging bag can be used as it is without being turned over when it is covered with the support frame of the packaging aid.

Hereinafter, the characteristics of the present invention will be described in detail with reference to the embodiments shown in the drawings.

1 is a perspective view of a packaging bag showing one embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along line A-A of the packaging bag shown in FIG.

The packaging bag 10 of the present embodiment is formed of a biaxially stretched transparent polypropylene, made of a front sheet 12 and a rear sheet 13 which protrudes above the front sheet 12 to form a lip 13a. . 11 is a joint portion of the front sheet 12 and the rear sheet 13 in the bottom formed by folding the sheet-like article is joined by the melting seal 14, thereby forming an encapsulation body having an opening at the top. The melted seal 14 is different from the area bonding method by thermal fusion, and as shown in the partially enlarged view of FIG. 1, by continuously continuous edges of the synthetic resin sheets 12 and 13 simultaneously with the melted edge, There is almost no distinction between the inside and the outside of the bag, and it can be used regardless of front and back, which has been formed into a sealing shape by this melting seal.

15 denoted by an imaginary line is a cut portion cut in a triangular shape by the melting seal 14 on both sides of the bottom portion 11 of the sealing body. As a result, the sealing corner portion, which has conventionally been difficult to reverse, is eliminated, thereby facilitating the reversal of the bag 10. As clearly shown in FIG. 2, a printing unit 16 on which the information indicating the contents is printed is formed on the inner side of the front sheet 12 by reverse printing. Therefore, when the bag 10 is inverted, the printing surface is inverted to become the outer surface, and in the packaging state, it is possible to observe the normal character information from the outside (Fig. 8).

Next, the manufacturing method of the said packaging bag 10 is demonstrated with reference to FIG.

As shown in Fig. 3 (a), the rectangular synthetic resin sheet S, in which the printing portion 16 is formed in advance on the upper surface side (which becomes the inner surface at the time of making the bag), is pushed away from the center slightly. As shown in FIG. 3 (b), the front sheet 12 and the rear sheet 13 are formed. Subsequently, as shown in FIG. 3 (c), the melted seal 14 is used to form portions that become both edges of the packaging bag 10 and simultaneously cut both sides of the bottom portion 11 in a triangular shape. The front sheet 12 and the rear sheet 13 are cut, and the front sheet 12 and the rear sheet 13 are bonded to each other. Thereby, the packaging bag 10 shown in FIG. 1 is completed.

FIG. 4 is an explanatory view showing the wrapping operation of the branch N using the packaging aid 51 described in the prior art. First, the bag 10 is placed upside down as shown in FIG. It does not cover the support frame 52, but covers it as it is. Therefore, in this state, the printing portion 16 is displayed on the inner side of the bag 10. Next, several branches N are held in hand and placed at the bottom of the bag 10 at the same time, and then the branches N are press-fitted into the bag 10 loaded on the support frame 52 (FIG. 4 (b)). ). Accordingly, the bag 10 is pressed against the branch N and the bottom part is pressed into the lower portion of the support frame 52. The bag 10 wraps the branch N while inverting and passes the support frame 52 together with the branch N. And fall to the work object in the packaged state (Fig. 4 (c)).

FIG. 8 is a perspective view showing this state, the packaging bag 10 is completely reversed in the state shown in FIG. 1, and the printing portion 16 is formed on the outer surface side of the bag 10, and is in a normal information display state. Moreover, by forming the cut part 15 triangularly cut | disconnected by the melting seal 14 on both sides of the bottom part 11, the corner part which is hard to reverse is eliminated, and only to drop the packaged object in the support frame 52 Easily reversed. After that, as in the conventional manner, the upper portion of the bag 10 in which the branches are put in a conventional manner is bundled with adhesive tape or heat-sealed to complete the packing.

In addition, in the above embodiment, in order to prevent contact between food and printing ink during packaging, the printing unit 16 is positioned inside the bag at the time of bag production. On the contrary, printing is performed outside the bag at the time of bag production. You can also have the noodles come. In such a configuration, since the printing portion 16 is located on the inner surface of the bag in a state where the goods are stored, the printing portion 16 comes in contact with another and peels off the printing as if printed on the outside. .
