Description

  The present invention relates to a packaging bag for storing a product, and more particularly to a packaging bag having a feature in an opening portion.

  The packaging bag is filled with the product in a sealed state. When taking out the filled product (contents), the packaging bag is torn and opened. Here, in order to open the fixed location of a packaging bag, the opening tape is stuck on many packaging bags. When the opening tape is pulled from one end, the opening tape is divided from the packaging bag, and the packaging bag is opened.

  However, the conventional opening tape is attached to the entire circumference along the circumference of the packaging bag, and when this is separated from the packaging bag, the entire upper portion of the packaging bag is opened. Thus, when the whole upper part of the packaging bag is opened, it is difficult to seal again even if the contents remaining after taking out a part are stored. Further, when the contents are liquid and need to be transferred to another container, the contents are likely to spill when the entire upper portion of the packaging bag is opened.

  This invention is made | formed in view of such a situation, and it aims at provision of the packaging bag which can form the taking-out port of the content in a part of packaging bag easily.

The packaging bag of the present invention is formed of a film-like packaging material, and a bag body having a shape in which the front and back surfaces are connected by an upper edge, a lower edge, and left and right side edges,
An opening guide portion extending at least to the other edge intersecting with the one edge of any one of the upper edge, the lower edge and the left and right side edges of the bag body,
A cut formed on the edge of the bag body,
The opening guide part is formed by folding the packaging material and heat-sealing at least the root part of the folded region,
The cut is a position where the packaging material is cut from the cut toward the opening guide part, and then the packaging material is cut along the opening guide part so that the cut constitutes an outlet for the contents filled in the bag body. It is formed in this.

As described above, the packaging bag of the present invention can form the outlet for contents by a simple operation. This outlet only opens a part of the packaging bag, and therefore there is little risk of unintentionally spilling out the contents, and re-sealing is easy.

  The cut may be formed in a heat seal portion formed along the upper edge of the bag body, or may be formed in a heat seal portion formed in a part of the upper edge of the bag body. Furthermore, you may form a cut | interruption in the upper end edge and one side edge of a bag main body, respectively.

  Furthermore, a cut | interruption can also be formed in several places along the upper end edge of a bag main body. If each cut is formed at an arbitrary distance set in advance from one side edge of the bag body, each of these cuts serves as a guide for the amount of content to be taken out, and a certain amount of content can be easily taken out. .

  You may form the guide seal part which tears and guides toward a opening guidance | induction part from a cut | interruption. The guide seal portion can be formed on the bag body by heat-sealing the packaging material. By forming such a guide seal portion, it is possible to stably cut from the cut to the opening guide portion. If the guide seal part is formed on both sides of the tear guide line from the cut to the opening guide part, it is possible to more stably cut the cut from the cut to the opening guide part.

  The opening guide part may have a configuration in which a folded part is formed along the take-out port and the spout is formed by folding the folded part. If comprised in this way, when a content is a liquid especially, it will function effectively as a guide at the time of taking out a content, and the spill of a content can be suppressed.

  The region between the opening guide portion and the upper end edge of the bag body may be configured to form a knob by bending along the opening guide portion. If the knob is configured in this manner, the contents can be taken out while holding the packaging bag firmly.

  Moreover, while forming a notch in the upper end edge of a bag main body, you may form the uneven | corrugated area | region for picking between the said cut and one side edge of a bag main body. When the packaging bag is torn from the cut, the unevenness for picking prevents slipping, so that the tearing operation can be performed easily and stably.

  Furthermore, the opening guide part can be extended in a direction inclined obliquely with respect to the upper end edge of the upper bag body to form an inclined outlet.

  Furthermore, according to the present invention, in the packaging bag in which the gusset folding portion is formed along at least one side edge of the bag body, it is preferable that the cut is formed inside the gusset folding portion.

The packaging bag of 1st Embodiment has the bag main body 1 of the shape where the surface and the back surface were connected by the upper end edge, the lower end edge, and the right and left side edge using the synthetic resin film (packaging material). . As shown in FIG. 1A, a vertical seal portion 2 and horizontal seal portions 3 and 4 are formed on the bag body 1 of the present embodiment by heat sealing. The bag body 1 is filled with a product (hereinafter also referred to as a content) before sealing.

  The vertical seal portion 2 of the bag body 1 is formed by superimposing both side edges of the belt-shaped packaging material in the vertical direction and heat-sealing the overlapped portion. The vertical seal portion 2 extends in the vertical direction at a substantially central portion on the back surface of the bag body 1.

  The horizontal seal portions 3 and 4 of the bag body 1 are formed by heat-sealing the upper and lower edges of the packaging material that has become cylindrical due to the formation of the vertical seal portion 2.

  In addition, the bag body 1 of the present embodiment is formed with an opening guide portion 5 extending in the circumferential direction with a certain distance from the lateral seal portions 3 and 4. The unsealing guide portion 5 is formed at a position relatively close to the lateral seal portion 3 on the upper edge side. As shown in FIG. 1B, the opening guide portion 5 is formed by folding a packaging material in a pleated shape, and this folded region (hereinafter referred to as a folded portion) is exposed on the outer surface of the bag body 1. ing.

  In the opening guide portion 5 of the present embodiment, the entire region of the folded portion is heat-sealed. The region to be heat-sealed does not have to be the entire region of the folded portion, and it is sufficient that at least the root portion 6a of the folded portion is heat-sealed. Moreover, you may adhere | attach a one part or all area | region using an adhesive agent instead of heat-sealing a folding part.

The bag body 1 has an opening cut 7 at the upper edge. The cut 7 is formed at a position away from the side edge of the bag body 1 by a certain distance, and is cut from the upper edge to the middle of the horizontal seal portion 3 in the vertical direction. The cut 7 is adjusted in the cutting direction so as to tear the lateral seal portion 3 in the vertical direction and further continuously tear the bag body 1 to the opening guide portion 5.

[Method of manufacturing packaging bag]
FIG. 2 is a perspective view showing an outline of a vertical bag making filling and packaging machine used for manufacturing a packaging bag according to the first embodiment.
The belt-shaped packaging material fed out from the packaging material roll 200 is formed into a cylindrical shape by the former 101 and the bag-making cylinder 102 of the vertical bag-making filling and packaging machine 100, and then the overlapping portion is heat-sealed by the vertical sealing device 103. Thus, the vertical seal portion 2 is formed. Thereafter, the lower side (upper edge of the packaging bag 1) of the packaging material formed into a cylindrical shape by the horizontal sealing device 104 is heat-sealed to form the horizontal sealing portion 3, and then the contents are filled into the interior, and then the side is again horizontal. The upper side of the packaging material (the lower end edge of the packaging bag 1) is heat-sealed by the sealing device 104, and the lateral seal portion 4 is formed. In this way, the sealed bag body 1 is manufactured. In addition, the bag main body 1 is manufactured upside down so that the opening guide portion 5 is not caught by the former 101 when the packaging bag is manufactured.

  Further, in the vertical bag making and filling and packaging machine 100, an opening guide part forming device 105 is installed on the feeding path of the packaging material. The opening guide part forming device 105 has a function of heat-sealing the folded portion after folding the belt-like packaging material in a pleat shape over the entire width in a direction substantially perpendicular to the conveying direction. The device 105 forms the opening guide 5 that extends linearly over the entire width of the belt-like packaging material.

[Opening procedure of packaging bag]
3A to 3D are perspective views showing a procedure for opening the packaging bag according to the first embodiment.
When the bag body 1 is opened, both the portions 3a and 3b of the lateral seal portion 3 are picked by fingers with the cut 7 as a boundary, and the portion 3a near the side edge of the bag body 1 is pulled downward. . Thereby, the bag body 1 comes torn from the cut 7. In this way, when the portion 3a near the side edge is pulled downward, the breaking line A proceeds in the same direction and longitudinally cuts through the horizontal seal portion 3 (see FIG. 3A). Further, when the portion 3a near the side edge is pulled down as it is, the breaking line A continues from the lateral seal portion 3 through the bag body 1 and reaches the root portion 6a of the opening guide portion 5 ( (See FIG. 3B).
In addition, when a laminated film is used for the packaging material forming the bag body 1, a number of longitudinal slits are formed in one layer, and the bag body 1 is guided by the slits and is easily torn in the longitudinal direction. You may comprise.

After the breaking line A reaches the opening guide portion 5, the portion 3a near the side edge is drawn in the horizontal direction (see FIG. 3C). Then, the breaking line A is guided along the opening guide portion 5 to the side edge of the bag body 1. When the breaking line A reaches the side edge, the small piece 8 including the portion 3a near the side edge is separated from the bag body 1 (see FIG. 3D). As a result, the outlet 10 opens at the corner portion on the upper edge of the bag body 1. The edge portion 11 of the outlet 10 is formed by a cut 12 formed by cutting the bag body 1 in the vertical direction and a cut 13 formed by cutting the bag body 1 in the horizontal direction along the opening guide portion 5. Yes.
As described above, since the small piece 8 can be separated and the outlet 10 can be formed by a simple opening procedure, even a relatively weak person can open the bag body 1 easily.

[Effects of outlet]
FIG. 4A is a perspective view showing a state in which the liquid L (contents) is taken out from the outlet of the packaging bag according to the first embodiment, and FIG. 4B shows a thin stick-like product S (such as dried pasta noodles) from the outlet. It is a perspective view which shows the state which takes out the content.
The cut 13 that forms the edge 11 of the outlet 10 of the bag body 1 is formed along the opening guide portion 5 formed by folding the packaging material, so that it is reasonably hard and has a waist. Therefore, for example, as shown in FIG. 4A, when the liquid L is poured out from the bag body 1, there is no possibility that the cut end 13 may be shaken irregularly due to the liquid pressure, and the liquid L is poured out stably in a certain direction. be able to.

  Moreover, the opening 10 formed by the above-described operation can adjust the opening area by arbitrarily setting the position of the cut 7 formed in the upper edge of the bag body 1. For example, as shown in FIG. 4B, with respect to the bag body 1 filled with a thin stick-shaped product S such as dried pasta noodles, the position of the cut end 7 is set so that the opening area is such that the stick-shaped product S can be taken out in a preset amount. If set, an almost constant amount of contents can be taken out from the outlet 10 each time.

FIG. 5A is a back view showing another method of using the packaging bag according to the first embodiment.

Thus, if the knob | pick part 20 is comprised, it will become possible to hold | maintain a packaging bag firmly and to take out the contents.

  In addition, for example, when the contents are transferred to a small opening container, it is convenient to bend the upper region of the opening guide 5 downward. That is, as shown in FIG. 5B, when the content is poured out without bending the upper region of the opening guide portion 5, the upper end corner portion 12 a of the cut end 12 is formed on the opening edge Pa of the container P to which the content is transferred. May interfere. Further, if the bag body 1 is tilted too much, the contents may spill out from the cut end 12 side and be scattered. On the other hand, as shown in FIG. 5C, there is no possibility that the upper end corner portion 12 a of the cut end 12 interferes with the opening edge Pa of the container P in a state where the upper region of the opening guide portion 5 is bent. Moreover, since the cut end 12 of the bag body 1 is closed and only the cut end 13 is opened, there is no possibility that the contents spill out from the cut end 12 side and be scattered.

In addition, this invention is not limited to embodiment mentioned above, Of course, various application implementation or deformation | transformation implementation is possible as needed.
For example, the packaging bag of the first embodiment is a vertical pillow type packaging form in which the upper and lower edges of the bag body 1 are the horizontal seal portions 3 and 4, but the present invention is not limited to this, and the present invention is as shown in FIG. 6A.
