A packaging bag 10 is made of transparent polypropylene in a shape formed of a front sheet 12 and a rear sheet 13 provided with a lip 13a projecting beyond the upper edge of the front sheet 12. The front sheet 12 and the rear sheet 13 are joined at their joining parts with fusing seals 14, and thereby a bag main body having an opening at its top is formed. Printing 16 indicating contents is made in reverse printing at the inside of the front sheet 12, and thereby the bag main body can be used regardless of its position where its inside being out, or its outside being in. On putting the packaging bag on a holding frame of an assisting device for packaging, the bag can be put without turning its inside out. In the case where the bag is positioned with its inside turned out, the printing comes to the surface side, being in normal position, and can be observed as normal characters on a packaged body from the outside.

Description

Package bag and manufacture method thereof

The present invention relates to the greengrocery of eggplant, cucumber, spinach etc. and the used package bag of packing of fruit and flowers class etc.

Greengrocery that supermarket etc. are located to sell and fruit, it is suitable number to be packaged in the bag that the film of synthetic resin of polyethylene etc. makes a laggard marketing sell mostly, generally speaking, this packing is to be concentrated in the process of payment such as supermarket from the producer at vegetables and fruit to carry out.

These facility places that are packaged in the agricultural cooperative society and so in the place of production carry out, and the facility that process load is many carries out with automatic packaging machine, and the facility that process load is few carries out with staff.

When carrying out package handling with staff, because the difference of vegetables or fruit, the efficient of its package handling is also significantly different.For example, eggplant, green pepper, apple and persimmon or the like, when several are packed into together the bag in the time, because being close to the film inside face easily, its surface is difficult to slide, so at the bottom of being difficult to enter bag, in addition, if in the bag of packing into successively one by one, though can relax the problem of being close to film, operating efficiency significantly descends.

When especially packing eggplant, because its global shape and suitable elastic force, eggplant surface each other also is adjacent to easily, when the 2nd, the 3rd is packed into the bag in the time, the eggplant surface can be adjacent on film, simultaneously, also can be adjacent to the eggplant surface of formerly packing into, the eggplant of packing into later on is in forward and backward all stuck-tight state easily.

As the measure that tackles, the inventor has designed a kind of packaging auxiliary frame earlier, and this device comprises that the packaging bag with through hole that packed article can pass through keeps frame, and approximate horizontal state ground supports the supporting station of an opening of the through hole of above-mentioned maintenance frame.Fig. 9 is the block diagram of this packaging auxiliary frame 51, and this packaging auxiliary frame 51 is broadly divided into maintenance frame 52, pillar 53 and pedestal 54 such three parts of ring-type.

Keep frame 52 that plastics or corrosion-resistant steel are done circlewise and make, by pillar 53, maintenance frame 52 is supported to the approximate horizontal state.The size that keeps the through hole of frame 52 be to pass through the size of the packed article of several eggplants etc.

Among 4 support foot 54a-54d of pedestal 54, keep pin 54a, the 54b of frame 52 sides longer, when using this packaging auxiliary frame 51, even also can the whole auxiliary frame of stable support during the load of being setovered with box lunch than pin 54c, the 54d of opposition side.

In the time of will packing eggplant N with packaging auxiliary frame 51, auxiliary frame 51 is placed on the suitable operator's station, at first, shown in Fig. 4 (a), bag H bottom is up covered on maintenance frame 52.Then, hand takes several eggplants N to make its bottom that leans against bag H simultaneously, eggplant N is pushed with bag H to keep in the frame 52 (Fig. 4 (b)) then.Therefore, bag H is pushed by eggplant N, and the bottom is pushed into the below that keeps frame 52, and bag H encases eggplant N while overturning, and passes through to keep to drop to (Fig. 4 (c)) on the operator's station within the frame 52 with eggplant N.

Like this, by adopting packaging auxiliary frame 51, the bag H that the bottom is made progress covers on the maintenance frame 52, and eggplant N is pushed in the maintenance frame 52 from the top of bag H, can the limit be inserted eggplant N in the bag H by a bag H upset limit.Therefore, to the process of (c), eggplant N keeps in touch with a bag H and moves simultaneously at (a) of Fig. 4, so, even smooth surface is closely attached on the eggplant N of bag H easily, also can insert swimmingly in bag H, pack expeditiously.

Yet the employed package bag H of such packing, three faces of two sides except that peristome and bottom surface are applying closedly by hot melt from the position of several mm of outside genesis, adorn what thing, the place of production, sellers' etc. information being printed on lateral surface in.Therefore, make package bag H be in the state shown in Fig. 4 (a), must keep the about upset of package bag H back cover on the frame 52, this operation is the very big obstacle that improves the package handling efficient of this use packaging auxiliary frame 51.

Therefore, the problem that the present invention will solve is, a kind of package bag and manufacture method thereof are provided, and the package bag of making need not be overturn just can use, the package handling efficient of the above-mentioned package bag that further raising use packaging auxiliary frame carries out.

In order to address the above problem, package bag of the present invention, it is characterized in that, have Printing Department at least and be the junction surface that forms with transparent synthetic resin sheet, top has goods to insert peristome, the periphery of usefulness seal by fusing engage, turnover package bag body, and be imprinted on this bag body medial surface or be imprinted on information on this bag body lateral surface by anti-printing by just printing.

In this so-called anti-printing, be meant such printing process, promptly, adopt this printing process, when seeing the information of pattern of being imprinted on bag body etc. at the bag state, this information presents the state that is seen as normal condition from rear side, at the bag state, can be divided into medial surface and the anti-such two kinds of situations of lateral surface that are printed on bag body of information that information just is being printed on bag body.Especially as the used for packing foods bag time, at the bag medial surface that just is being printed on bag body in the best state, so that the information lateral surface that food and the printing ink of printing usefulness can not contact can be located at packing the time bag.In addition, fusing and seal with bonding different by the face of heat seal, is in fusing, makes linear mutually connection of edge of synthetic resin sheet, seals the packaging bag of making pouch by this fusing, irrespectively uses in can showing.

In addition, for the package handling that uses the packaging auxiliary frame carries out the upset operation of bag easily, can seal the leg-of-mutton excision of formation portion by fusing in the two bottom sides of above-mentioned bag body.

Have again,, then can make package bag is covered on the operation automation that keeps on the frame if the anter or the rear panel that constitute above-mentioned bag body are more stretched out to top than another sheet.

In addition, be printed with the package bag of information at medial surface at the bag state, available and present roughly the same operation is made, promptly this manufacture method is, the flap surface of making at transparent synthetic resin stamps information, and the folding flap forms the base section of package bag, and makes the face that is printed on above-mentioned information be positioned at the inboard, seal the above-mentioned flap that cuts off behind the folding by fusing, form the both sides of the edge part of package bag.

As mentioned above, seal a formation bag body, and just print at the medial surface of this bag body by fusing, or print in that lateral surface is counter, when on the maintenance frame that this package bag is covered on the packaging auxiliary frame, need not about overturn, can cover use with original state.
