BACKGROUND OF THE INVENTION
The present invention relates to a liquid packaging container that contains a liquid detergent, a liquid softening agent, or the like.
[0002]
[Problems to be solved by the invention]
Conventionally, a bottle type container made of synthetic resin or the like has been problematic in that it tends to cause an increase in dust and environmental destruction by performing disposal when it is not needed. Under these circumstances, products such as kitchen detergents, laundry detergents, liquid softeners, shampoos, rinses, and body soaps, which have been used in large households in recent years, have an environmental impact as refills. The container which selected the material which considered this, Comprising: It has come to be provided using the liquid packaging container of the shape which is hard to bulk.
FIG. 10 shows a liquid packaging container 1 called a standing pouch designed to answer such a request. The liquid packaging container 1 is composed of a front sheet 2, a back sheet 3 and a bottom sheet 4 each having a laminated structure. Then, the front sheet 2 and the back sheet 3 are bonded together with the bottom sheet 4 interposed (for example, heat sealing), and the space between the lower side of the front sheet 2 and the lower side of the back sheet 3 at the bottom of the container is widened. It is in a form that can stand on its own. When transferring the contents to the empty container, the container upper part 6 is cut in the horizontal direction and poured into the empty container or the like from the cut end.
[0003]
In addition, in order to easily pour out the liquid after opening, one corner of the container upper part 6 is cut obliquely instead of being cut horizontally along the container upper part 6 having a linear shape at the upper end. It is also performed to obtain a cutting edge.
However, when the corner of the container is cut obliquely, even if the notch 8 is provided in the container side 7 and the container is opened manually by using it as a cutting start, it is unstable to apply the cutting force to the container. The cutting direction is difficult to control because it is easily affected by the lines and the like formed during the formation of the sheet and the back sheet. For example, as shown in FIG. 11A, the width of the liquid packaging container 1 is more than necessary. Or the shape of the cut surface obtained by the cutting may be shortened to the upper side along the container side edge 7 of the liquid packaging container 1 as shown in (b). In order to obtain a stable cut at the present time, it has been necessary to cut using a cutting tool such as a scissors.
[0004]
Therefore, the liquid packaging container 1 shown in FIGS. In the liquid packaging container 1, as shown in the figure, one of the upper parts 6 of the container 6 in which the upper side 2 a of the front sheet 2 and the upper side 3 a of the back sheet 3 are bonded together by heat sealing so that the upper end is linear. At the corners, there is provided a substantially triangular opening knob allowance 9 formed by directly heat-sealing the front sheet 2 and the back sheet 3. In the opening knob allowance 9 formed by integrating the triangular regions of the front sheet 2 and the back sheet 3, the boundary edge 10 with the inner side of the container is inclined, and the opening knob 6 from the container upper part 6 side. It is inclined in a straight line toward the container side portion 7 where the margin 9 is located.
Thus, the opening tab allowance 9 becomes hard because the front sheet 2 and the back sheet 3 are integrated by bonding by heat sealing at one corner in the upper part 6 of the container, thereby forming an accommodation space for the container 1. It becomes harder than the seat part. Therefore, if the opening tab 9 is held and cut into pieces, the cutting edge at the time of cutting is guided to the boundary edge 10 so as to advance linearly, and a cut having no variation in size and shape is obtained. Be able to.
Further, in this liquid packaging container 1, in order to make the position of the cut edge clearer, the boundary is set along the boundary edge 10 of the opening knob allowance 9 and at a position outside the area of the knob allowance 9. A linear opening position display line 11 is provided so as to be close to the edge 10, and the opening position display line 11 is provided so that the opening opening display line 11 is provided even when the opening knob margin 9 is held and is torn off. It becomes easier to proceed with cutting while confirming the position display line 11, and a more appropriate cut can be formed.
On the extended line 11a of the inclined opening position display line 11 and on the container side portion 7 of the container 1, there is a notch 8 for facilitating the formation of the cutting start edge at the time of cutting as in the conventional example. As shown in FIG. 2, in the notch 8, one notch edge 12 is aligned in the cutting direction so that the cutting start end advances.
[0005]
Accordingly, an object of the present invention is to make it possible to perform cutting at a set position without using a tool such as a scissors when cutting one corner of the upper part of the container. The purpose is to make it possible to easily obtain a reasonable cut by simple manual operation.

In the liquid packaging container 1 of the present invention, the front sheet 2 and the back sheet 3 are bonded together with the bottom sheet 4 interposed at the bottom of the container. As shown in FIGS. A range that does not protrude from a substantially rectangular area when the liquid packaging container 1 is viewed from the side (that is, does not protrude upward from the upper end position of the upper portion of the container, and the side end position of the container side portion). The spout portion 14 is provided between the upper and side recesses 13 and protrudes in the form of a beak. In the example of FIG. 3, an opening knob allowance 9 formed by directly heat-sealing the front sheet 2 and the back sheet 3 is provided at the front end position of the spout 14 of the container 1. In this unsealing knob allowance 9 which is integrated by heat sealing with the back sheet 3, the boundary edge 10 with the inner side of the container is inclined, and the container side edge 7 side from the container upper part 6 side in the spout part 14 Inclined in a straight line toward
And in the said spout part 4, in order to clarify the position made into a cut end, it is along the boundary edge 10 of the knob allowance 9 for opening, and a boundary edge in the position outside the area | region of this knob allowance 9 10 is provided with a linear opening position display line 11 so as to approach 10, and this opening position display line 11 is provided so that even when the opening knob margin 9 is held, the opening position display line 11 is provided. It becomes easier to proceed with cutting while confirming the display line 11, and a more appropriate cut can be formed.
Furthermore, it is the position of the inclined opening position display line 11 at the spout part 4 having a beak-shaped shape, and the cutting start end at the time of cutting is placed on the container upper part 6 and the container side part 7 in the spout part 4. There is a notch 8 for easy formation.
And in the liquid packaging container 1 provided with the beak-shaped spout part 4 illustrated in FIG. 3 to FIG. 6, the boundary position with the container inner side in the container side part at the spout part 4 is displayed in the above-mentioned opening position display. It is inclined so as to be orthogonal to the line 11 so as to be close to the notch 8.
Further, a protruding piece 15 is provided on the upper edge side of the opening tab allowance 9 so that the cut edge of the notch 8 can be formed more easily and with a small force. The area that can be held is increased upward. Similarly, FIG. 4 shows an example in which an overhanging piece 15 is extended on the lower side of the side of the unsealing knob allowance 9. FIG. 5 shows an overhanging piece 15 having a size different from the upper side and the side. FIG. 6 shows an example in which extending pieces 15 are extended in three directions.
[0008]
3 to 6, reference numeral 16 denotes a part that is located inside the spout part 14 and maintains the open shape of the spout part at the time of pouring. An example of the component 16 is shown in FIG. 7, and the three pieces 16a are provided so as to be foldable into a substantially U-shaped cross section via the folding portion 16b, and are arranged in a flat state. (See FIG. 7 (a)), it is made into a bowl shape by folding up after opening (see FIG. 7 (b)), and the opening of the spout is maintained.
[0009]
In the liquid packaging container 1 of the example in which the upper end of the container upper part 6 shown in FIG. 8 is linear, the container upper part 6 side of the boundary edge 10 in the opening allowance 9 is vertically provided in the container vertical direction. The container upper part 6 is orthogonal to the length direction. In this liquid packaging container 1, the container bottom part and both container side parts are formed by heat sealing, and are formed in advance in a state where the upper side of the front sheet and the back sheet is opened. After filling the contents, this upper side is heat-sealed to obtain a closed container upper part. Therefore, as described above, in this example, the opening tab allowance 9 formed in advance by heat sealing is provided with the vertical vertical edge 17 rising from the region corresponding to the container storage space on the container upper side of the boundary edge 10. Therefore, the opening width 18 at the time of filling the contents can be ensured widely. In the figure, reference numeral 6a denotes a sealing region for obtaining a closed container upper part.
[0010]
As shown in FIG. 8, in the liquid packaging container 1, the linear opening position display line 11 is provided at one corner of the container upper portion 6, and an extension line 11 a of the opening position display line 11 is provided. A notch 8 for opening is provided on the upper side, and a portion where the opening position display line 11 and the extension line 11a pass in the container side portion 7 is a wide heat seal portion 19. And the boundary edge 20 which is the boundary edge with the container inner side in the heat seal part 19, Comprising: The opening position display line 11 and its extension line 11a are orthogonal to the opening position display line 11 and its extension line. And is close to the notch 8 as shown. Thus, since the unsealing position display line 11 and the extension line 11a of which the cutting edge advances from the notch 8 and the boundary edge 20 are orthogonal to each other, the cutting edge generated at the notch 8 is heat-sealed. When entering the storage space area of the front sheet 2 and the back sheet 3 that are not heat-sealed from the container side edge 7, that is, when cutting the boundary edge 20, the resistance to the progress of the cutting edge is the smallest, The factor causing the blur in the traveling direction of the cutting edge (distortion and elongation of the front sheet and the back sheet) is minimized, and the cutting edge appropriately proceeds on the opening position display line 11. Therefore, even when a cutting edge enters the sheet portion of the storage space area, it is difficult to cause a fork split (a state in which the cutting edges of the front sheet and the back sheet are displaced).
In the example shown in FIG. 8, the boundary edge 20 intersecting the opening position display line 11 and its extension line is formed in the wide heat seal part 19 in the container side part 7, but as shown in FIG. A narrow heat seal portion 21 may be formed on the side portion 7, and a boundary edge 20 may be provided in the narrow heat seal portion 21 so as to be close to the notch 8. That is, as long as the sealing strength of the container side edge 7 is not impaired, the boundary edge 20 may be positioned inside the container side edge 7.
In addition, the point which provides the boundary edge 20 which cross | intersects the opening position display line 11 and its extension line 11a in the container side part 7 is not limited to the container 1 which has the vertical edge 17 shown in FIG.8 and FIG.9. It can also be implemented in the container shown in FIG.
