First, the continuous supply of packaging bags according to the present invention will be explained. The method involves hanging both shoulders 3.3 of a plurality of continuous packaging bags I, which are connected so as to be separable with a tensile force greater than a predetermined value, through a pair of parallel rods 8.8. A continuous type of packaging bag l by hanging the packaging bag l
is temporarily fixed to the base end 111+1 of the shaft 8.8 to hold it in a folded and overlapping state, and the preceding packaging bag 1a is pulled and slid toward the tip side of the shaft 8.8 to maintain the open state. When the packaging bag 1a is opened, any article can be put into it, and then the preceding packaging bag 1a is forcibly pulled and pulled out from the shaft rods 8, 8. Following this, the following packaging bag 1b is pulled from the temporarily fixed state of the base ends of the shaft levers 8, 8 to the tip side of the shaft rod 8.7 and slides into an open state, and at the same time, the preceding packaging bag 1b is It is characterized by tearing the bag 1a from the succeeding packaging bag 1b to separate it, and the pressing tool 10 is made by applying an appropriately set biasing force to the continuous packaging bag 1 using a spring 9 or other means. to temporarily fix it to the proximal end side of the shaft rod 8.8 to maintain the overlapping state, and to push the continuous packaging bag l through the pin 12 having an expanded diameter head. This includes temporarily fixing it to the base end side of the shaft rod 8.8 and maintaining it in an overlapping state.

Next, the N4 structure of the packaging bag according to the present invention includes a plurality of packaging bags 1
A pair of shaft rods 8.3 are connected to each other so as to be separable by a tensile force of a predetermined value or more, and a pair of shaft rods 8.3 are arranged in parallel at both shoulder portions 3.3.
8 is characterized by forming a hanging hole 4.4 through which it can be hung.

Effect: By the means described above, the preceding packaging bag 1a can be suspended and held in an open state by the pair of parallel rods 8.8, and the packaging bag 1a in the open state can be freely loaded as it is. Purchased items etc. can be put in.

After putting in shopping items, etc., when the packaging bag 1a is forcibly pulled and pulled outward from the tip of the shaft 8.8, it is temporarily attached to the base end of the shaft 8.8. At the same time as the following packaging bag 1b, which is stopped and waiting, is opened by sliding on the shaft lever 8.8, the aforementioned packaging bag 1a is torn off and separated from the following packaging bag 1b. can be,
By repeating this process, the packaging bag l is attached to a pair of rods 8.
It can be continuously opened and held in a suspended state at 8 degrees.

EXAMPLES Below, examples illustrating the present invention will be explained. First, the structure of the packaging bag l is as shown in FIGS. 1 and 2. In use, each packaging bag l has a perforation or a hole in both shoulder parts 3, 3 of which the handle can form a hole 2, which can be hung through a pair of shaft rods, which will be described later. The packaging bags 1 can be separated from each other by a tensile force exceeding a predetermined value at the upper edge of the tongue portion 5 which forms a hot water hole 4.4 consisting of a loop or the like and extends to the upper center of the tongue portion 5. A temporary connecting portion 6 is formed by using slight welding, slight adhesive, perforation, or other appropriate temporary connecting means.

A pair of shaft rods 8.8 are horizontally protruded in parallel and superimposed on an appropriate wall surface 7, such as the side wall surface of a counter table installed in a calculation station called a cash register in a store, or a vertical wall surface specially formed. At the same time, a suppressor 10 is provided at the middle upper part of the shaft rod 8.8, and is provided with a spring 9 to apply an appropriately set biasing force.

The plurality of continuous packaging bags l described above are attached to a pair of shaft rods 8.8 provided on the wall surface 7 as shown in FIG.
The hot water holes 4, 4 of the continuous packaging bags L are hung through them, and the tongue portions 5 of the continuous packaging bags L are pressed with a pressing tool 9, so that the continuous packaging bags L are suspended. At the same time, the tongue piece 5a on the surface side of the preceding packaging bag 1a is removed from the pressing tool 9, and the packaging bag 1a is held in the folded and overlapping state by temporarily fixing it on the base end side of the rod 8.8. 8.8 and slides on the shaft rod 7.7 to form an open state as shown in Figure 1. Such an opening! Purchasing items and the like can be directly placed in the lower packaging bag 1a.

After the shopping bag 1a has been loaded with shopping items, the packaging bag 1a is forcibly pulled against the urging force of the pressing tool 9 that presses the tongue portion 5b on the back side of the packaging bag 1a, and the pivot rod 8.8 is pulled. When the packaging bag 1a is pulled outward from the tip, the tongue piece 5b on the back side of the packaging bag 1a is connected to the tongue piece 4a on the front side of the subsequent packaging bag 1b by the temporary connecting part 5. The tongue piece 4a on the front surface side of the packaging bag 1b follows the preceding packaging bag 1a to break free from the temporary fixing state by the suppressor 9, and the subsequent packaging bag 1b
The both shoulders 3.3 of the packaging bag 3.3 slide distally on the shaft rod 8.8, and assume the open state instead of the preceding packaging bag 1a.

At this stage, the preceding packaging bag 1a, which has been pulled outward from the shaft rod 8.8, has its tongue portion 5b attached to the succeeding packaging bag 1.
It is torn off and separated from the tongue portion 5a at point b.

By repeating this process sequence, the packaging bag 1 can be successively opened and suspended from the pair of shaft rods 8.8.

Fig. 4 shows another example of a case where a plurality of continuous packaging bags l are temporarily fixed to the wall surface 7 side, which is the proximal end side of the shaft rod 8.8, and are held in a folded and superimposed state. A perforation 11 is provided in the tongue portion 5 of the packaging bag 1, and a pin 12 having an enlarged diameter head removably implanted in the wall surface 7 is inserted through the perforation 11.

With this configuration, when each tongue portion 5 of each packaging bag 1 is pulled and removed from its temporarily fixed state, the periphery of the perforation 11 is torn or stretched, and the pin 12 is forcibly removed. It goes beyond the enlarged diameter area.

Incidentally, it is also possible to set the shaft rod 8.8 to be long so that a plurality of packaging bags 1 such as three bags or a ball bag can be opened at the same time, which is included in the present invention.

Effects of the Invention As described above, the present invention allows packaging bags to be continuously and sequentially opened and supplied, which is extremely convenient.
This has the excellent effect of greatly speeding up and saving labor for packaging shopping items at toll gates such as cash registers in stores and in the vicinity thereof.
