Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a packaging bag for storing a refill liquid.
[0002]
[Prior art]
Some kinds of liquids such as detergents are stored in a bottle with a pump attached and taken out little by little through the pump. Recently, when the detergent or the like in a bottle is used up from an environmental point of view, instead of directly discarding the bottle, the bottle is refilled with new contents and reused. As a packaging bag for storing such a replenisher, a packaging bag having a spout with a pipe inserted at one corner as shown in FIG. 2 is used. In FIG. 2, a packaging bag 1 is a self-supporting packaging bag in which a bottom 2 and a peripheral edge 3 are fused, and a spout 4 is provided at one corner. A pipe 5 is inserted into the spout 4. A notch 6 or the like is provided at the cutting position of the tip of the spout 4, and the upper edge portion 7 is in an unfused state. At the time of use, the film is cut and opened from the notch portion 6 at the tip of the spout 4, the pipe is projected from the tip of the spout 4, and the replenisher is injected into the bottle or the like through the pipe. The packaging bag having such a shape is opposed to two laminated films having at least one surface as a heat-adhesive layer so that the inner surface serves as a heat-adhesive layer, in the same manner as in a normal self-supporting packaging bag manufacturing method. In addition, a laminated film having a heat-adhesive layer at the bottom is interposed as a half-folded shape so that the outer side becomes a heat-adhesive layer, and the film corresponding to the spout is rounded and used for pouring there. The pipe was placed, and then the peripheral edge portions of both the front and back films were heat-sealed, leaving the upper edge portion, and the spout portion was punched out by punching along its contour.
[0003]
[Problems to be solved by the invention]
After filling the packaging bag with the contents, the upper edge is sealed, and when used, the film corresponding to the spout is removed to open and the contents are poured out. In the film of a part, there was a fault that it was difficult to open because the area held by hand was small.
Therefore, the present inventor has completed the present invention as a result of various studies to improve this defect, and an object of the present invention is to provide a refillable packaging bag that is easy to handle.
[0004]
[Means for Solving the Problems]
Gist of the present invention, along the contour of the part forming the spout of refill packaging bag having a spout inserted pipe at a corner, the note perforation or laser as an outlet outside the film remains the cutting line by line, a packaging bag wherein Note pipe from the tip portion of the outlet can be opened by hand so as to protrude with said spout when cutting the cutting line protrudes obliquely upward, the Two cutting lines from the upper side and the side side of the packaging bag are provided toward the base of the spout, respectively, and from the vicinity of the spout to the tip of the pipe along the outline of the spout Te provided with terminating from the end of the pipe before the position, the holes serving as a positioning notch for cutting for cutting the film portion where the spout of the pipe is present at the end of the cutting line The spout is formed in both sides of the pipe, the cut line is terminated in the hole, and the cut line is extended from one hole to the other hole in the film of the spout portion. It is a packaging bag for refill having. That is, in the refill packaging bag of the present invention, the outer side of the spout portion is not punched and removed during bag forming, but a cutting line is simply provided by a perforation or a laser beam. a taken as the integrally fused to the front and back film portions, during opening of the packaging bag has a large area of the portion having since the outer portion of the spout portion, cutting line by perforation or laser over line can be more easily removed, also the film spout portion along該切breakage because holes are formed for positioning the cutting the film portion pouring opening of the pipe is present At the same time, the pipe can be removed.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a front view of a packaging bag according to the present invention. 1 is the same as FIG. 2, 1 is a packaging bag, 2 is its bottom, 3 is a peripheral edge, 4 is a spout, 5 is a pipe, and 7 is an upper edge. In the present invention, a planned cutting line 9 by a perforation or a laser beam is provided along the outline of the spout without punching out the outer portion 8 of the spout 4. Moreover, the hole 10 is provided instead of the notch 6 of the conventional packaging bag. The outer portion 8 of the spout 4 may be fused with the front and back films, or may remain unsealed.
[0006]
In such a packaging bag, the contents are filled from the upper edge portion 7 in an unfused state as in the case of FIG. And in the packaging bag 1 of this invention, since the outer part 8 of the spout 4 remains only by providing the cutting line, the area of the part which has a packaging bag is large, and handling becomes easy. .
In use, the contents can be poured into a bottle or the like by removing the outer portion 8 by the perforation line or the cutting line 9 by a laser beam and cutting the pipe from the position of the hole provided earlier.
[0007]
【The invention's effect】
As described above, in the packaging bag of the present invention, the portion to be removed outside of the spout remains, so that the portion it has is large, thereby providing the effect of being easy to open.
