Packaging bag

The present invention relates to be used for the powder of preferences such as tealeaves such as packed green tea, black tea, oolong tea or coffee powder or pack dried stripped tuna abrasive dust or flavoring that little black carp does etc. or other ooze out packaging bag with food dressing.

Be used to make the above-mentioned packaging bag of oozing out with food dressing (hereinafter referred to as content) of oozing out, be used for tea in bag more, the bag of accommodating content is flat square, during use this bag is vertically hung down.Japanese patent gazette spy opens flat 1-99975 number and the spy opens in flat 3-98870 number, has disclosed and can improve the packaging bag of oozing out efficient.

Figure 17 and Figure 18 represent that the spy opens the packaging bag 100 that discloses for flat 1-99975 number.This packaging bag 100 has flats bag 110 and the messenger wire 120 that is installed on the bag 110.Bag 110 forms being cut into sealing of tetragonal 2 bag materials on every side.One end 130 of messenger wire 120 is connecting the one side central authorities of bag 110, and the other end is wound up into another side always.At the other end of this messenger wire 120, the label of being made by scraps of paper etc. 140 is installed, these scraps of paper 140 are bonded on the another side of bag 110 lightly.

During use, as shown in figure 18, label 140 is taken off from bag 110, bag 110 is hung down horizontally, hot-water flooding on the bag 110 with messenger wire 120.The hot water that injects oozes out content, falls in the container 150 of below.At this moment, because the downside of bag 110, can ooze out so hot water and content contact frequency are many well toward sagging.

Figure 19 to Figure 20 represents that the spy opens the packaging bag 200 that discloses for flat 3-98870 number.This packaging bag 200 is made of the bag 210 of triangular pyramidal and the messenger wire 220 that is installed on the bag 210.One end of messenger wire 220 is connecting the summit of bag 210 or the summary central authorities of one side.230 are mounted in the label on messenger wire 220 other ends.

Figure 19 represents this packaging bag 200 is contained in the interior form of outer bag (figure does not show), and the bag 210 of triangular pyramidal is suitably folded, and messenger wire 220 is wrapped on this bag that is folding.Label 230 is bonded at the outside of bag 210 lightly, like this, is keeping the folded state of bag 210 by messenger wire 220, reinstalls in the outer bag.

During use,, pinch label 230, bag 210 is hung down, be dipped in the hot water in the container 150 by messenger wire 220 as Figure 20 and shown in Figure 21.Figure 20 is the situation of an end of expression messenger wire 220 when connecting a summit of bag 220, and the face of triangle is positioned at downside.Figure 21 is that an end of expression messenger wire 220 is connected the situation on the face of bag 210, and a summit is positioned at downside.Which kind of situation no matter, because bag 210 is triangular pyramidals, its inner space is big, content and hot water contact frequency are many, can ooze out well.

Figure 17 and existing packaging bag 100 shown in Figure 180 are because bag 110 is flat, so in the outer bag of easily packing into.But this packaging bag 100 is because its bag 110 forms by upper and lower surface, so the interior narrow space of bag 110.Therefore, the content charging quantity in this bag 110 is restricted, and the removable amount of content in bag 110 is big inadequately, and content is insufficient with contacting of hot water when oozing out.Thereby this packaging bag 100 still exists the problem that can not fully ooze out.

Figure 19 is to existing packaging bag 200 shown in Figure 21, because the space that its bag 210 is triangular pyramidals, the space is big, the content of enough volumes of packing into.But, this packaging bag 200, volume is big during its folded state, so bag the time blocks outer bag easily outside packing into, is not easy to pack into.In addition, when folded state, as shown in figure 19, be the irregular contour of only tying coileds by messenger wire 220.Its profile is not beautiful, and is unbecoming when taking out from outer bag, influences commodity value.

Current packaging body 100,200 because messenger wire 120,220 all is wrapped in the outside of bag 110,210, so the length of messenger wire 120,220 is corresponding with the oad of bag 110,210, can not do long enough.Like this, when oozing out, messenger wire 120,220 is fallen in the container 150 easily.In order to address this problem, once considered messenger wire around bag 2 circles, 3 circles, to guarantee its length, but so, not only outward appearance is not good enough as packaging body, and outside packing into when bag messenger wire easily with outer bag interference, simultaneously, on the manufacturing line of packaging bag, to be not easy also to accomplish that this method is impracticable around 2 circles, 3 circles.

The present invention makes in view of the above problems, and its purpose is to provide a kind of packaging bag, the content of this packaging bag energy filling q.s, and content oozes out the efficient height, and it is big that volume does not show, the outer bag of packing into easily, and good looking appearance.
