Hereinafter, more specific embodiments of the present invention will be described with reference to the drawings.

The easy-open packaging bag 1 of one Embodiment is comprised by the front side sheet | seat 2 of the front rectangular shape, and the back side sheet | seat 3 of the front rectangular shape, as shown in FIG. 1 thru | or FIG. The front sheet 2 and the back sheet 3 are made of a synthetic resin material. The kind of the synthetic resin is not particularly limited. For example, polyethylene, polypropylene, polyethylene terephthalate, polyamide, or those obtained by laminating these synthetic resin layers in a plurality of layers, and further to the synthetic resin layer as described above. In addition, a so-called aluminum laminate sheet or the like in which aluminum is laminated can be used.

As shown in FIGS. 2 to 5, the peripheral portions of the front side sheet 2 and the back side sheet 3 are sealed by heat sealing, ultrasonic sealing or the like, and the portion surrounded by the sealing portion of the peripheral portion is not sealed. An accommodating portion 4 having a space in which an object can be accommodated is formed between the upper sheet 2 and the lower sheet 3. In the present embodiment, the upper seal portion 5a, the side seal portions 5b, 5c, and the bottom seal portion 5d are formed on the top, bottom, and both sides of the packaging bag 1, respectively, so as to surround the accommodating portion 4. A packaging bag 1 in a form called a so-called four-way pouch is formed.

  The housing part 4 surrounded by the four seal parts 5a, 5b, 5c, and 5d is formed in a substantially parallelogram shape on the front, and a semicircular arc-shaped part on the upper right side and the lower left side thereof. 4a and 4b are formed. Also, oblique side portions 4c and 4d are formed on the upper left side and the lower right side of the accommodating portion 4. And it forms as the outlet formation part 6 which forms the outlet 13 for taking out a to-be-contained object from the oblique side part 4c of the upper left side to the arc-shaped part 4a of the upper right side. A notch 7 that is an opening start point is formed on one side edge of the upper portion of the packaging bag 1 on the side of the outlet forming portion 6. This notch 7 is formed by a slit-like cut.

  A substantially semicircular protruding rib 8 that protrudes in the opposite direction to the tearing direction when viewed from the front is formed in the gripping part of the finger when tearing, immediately above the notch 7 that is the opening start point. . The protruding rib 8 is formed such that a line connecting the one end 8a and the other end 8b forming a substantially semicircular arc is slightly inclined from the vertical direction.

  Further, an auxiliary projection 9 is formed at the central point of the substantially semicircular arc of the projection rib 8. The auxiliary projections 9 complement the effect of preventing the fingers from slipping by the projection ribs 8.

  Further, a fixed gripping protrusion 10 is formed at a position immediately below the notch 7 and on the opposite side of the auxiliary protrusion 9 with the other end 8b of the protrusion rib 8 interposed therebetween. This fixed gripping protrusion 10 is gripped by the finger on the opposite side when the easy-open packaging bag 1 is opened with the notch 7 as an opening starting point by gripping the protrusion rib 8 and the auxiliary protrusion 9 with the finger. It is a protrusion for fixing. For example, when opening the easy-open packaging bag 1 by holding the protruding ribs 8 and the auxiliary protrusions 9 with the right finger, holding the fixed holding protrusion 10 with the left finger will open the right finger in a stable state. It can be performed. At this time, the above-mentioned fixed gripping projection 10 does not cause the left finger to slip.

  Further, an outlet deformation preventing rib 11 is formed on the upper side of the housing portion 4 in an obliquely vertical direction. The rib 11 for preventing deformation of the outlet is for preventing the outlet 6 from being deformed after opening the easy-open packaging bag 1 with the notch 7 as an opening starting point, and maintaining the shape of the outlet 6. Is.

In such an easy-open packaging bag 1, the front sheet 2 and the back sheet 3 are formed in the same form. That is, the outlet forming portion 6, the notch 7, the protrusion rib 8, the auxiliary protrusion 9, the fixed gripping protrusion 10, and the outlet deformation preventing rib 11 are formed on both the front side sheet 2 and the back side sheet 3, respectively. ing.

In terms of the properties or functions of the easy-open packaging bag 1 of the present embodiment called a pouch, there is no particular distinction between the front and back sides, but in the present embodiment, the front side sheet 2 and the back side sheet 3 are described for convenience. To do.

And the easy-open packaging bag 1 which consists of such a structure accommodates various things, such as a chemical | medical agent, foodstuffs, cosmetics, a seasoning, a detergent, and a shampoo, in the accommodating part 4, and subdivision packaging and refilling It is used for a wide range of purposes. The type of the object to be stored is not questioned, and the property of the object to be stored is not questioned, but in the present invention, it is mainly applied to a powdered object to be stored.

2 to 6 do not show the contents to be contained, but actually the contents are filled between the front sheet 1 and the back sheet 2 before the easy-open packaging bag 1 is made. The four peripheral edges are sealed to form the upper seal portion 5a, the side seal portions 5b, 5c, and the bottom seal portion 5d, so that when the easy-open packaging bag 1 is completed, it is already contained. The object is in a state of being accommodated in the accommodating portion 4.

Further, as shown in FIG. 7, a plurality of the easy-open packaging bags 1 as described above can be provided continuously through the perforation 16.

Next, the case of opening the easy-open packaging bag 1 as described above will be described. First, as shown in FIG. 8, before opening the easy-open packaging bag 1 starting from the notch 7 which is the opening start point. For holding the protrusion rib 8 and the auxiliary protrusion 9 with one finger 14 (for example, a right finger for a right-handed user) and for fixed holding with the other finger 15 (for example, a right finger for a left-handed user) The protrusion 10 is gripped.

In this state, as shown in FIG. 9, the upper seal portion 5a of the easy-open packaging bag 1 is torn from one side edge side to the other side edge side of the easy-open packaging bag 1 in which the notch 7 is formed. . Thus, by tearing the upper seal portion 5a from the one side edge side toward the other side edge side, the upper seal portion 5a is torn as shown in FIG.

  In this case, before opening the easy-open packaging bag 1, the user grasps the substantially semicircular projecting rib 8 protruding on the opposite side to the tearing direction with one finger 14, Since the upper seal portion 5a is torn away from the portion where the protruding rib 8 protrudes in a substantially semicircular shape, an anti-slip action is effectively exhibited along the inner side of the approximately semicircular protruding rib 8. As a result, when tearing with the notch 7 as the opening start point, even if the direction in which the tearing force is applied fluctuates somewhat, the anti-slip effect is not reduced.

In particular, the protruding rib 8 is formed such that a line connecting the one end 8a and the other end 8b forming a substantially semicircular arc is inclined slightly from the vertical direction, so that a tearing force is applied. The effect of maintaining the anti-slip action can be further improved even if the fluctuations occur.

  Further, since the auxiliary protrusion 9 is formed at the center point of the substantially semicircular arc of the protruding rib 8, when the user grips the protruding rib 8 with one finger 14, the protruding rib 9 The auxiliary projection 9 positioned at the center point of the substantially semicircular arc of 8 is also gripped at the same time, complementing the anti-slip effect of the finger by the projection rib 8 and further improving the anti-slip effect. Become.

Furthermore, since the outlet deformation preventing rib 11 is formed obliquely in the vertical direction on the upper side of the accommodating portion 4, after opening the easy-open packaging bag 1 with the notch 7 as an opening start point, The opening 6 is prevented from becoming small by deforming or crushing the outlet 6 and the shape of the outlet 6 is maintained.

Then, as described above, the upper seal portion 5a of the easy-open packaging bag 1 is torn from the one side edge side toward the other side edge side, and the torn outlet seal 6a is cut off and removed, whereby the take-out port 6 is removed. When the upper portion and the lower portion of the easy-open packaging bag 1 are reversed as shown in FIG. 10 in the fully opened state, the powder 16 that is an object to be contained is removed from the outlet 6 as shown in FIG. Will be discharged.

In this case, since the oblique side portion 4c is formed in the upper portion of the easy-open packaging bag 1, the easy-open packaging bag 1 is inverted so that the upper portion of the easy-open packaging bag 1 faces downward. When the outlet 6 is opened so as to spread in the lateral direction, the shape of the vicinity of the outlet 6 becomes a substantially funnel shape along the oblique side portion 4c, and as a result, the shape becomes a substantially funnel shape. Accordingly, the powder 16 is likely to be converged in the vicinity of the outlet 6, and is easily discharged from the outlet 6, and powder scattering is also suitably prevented.

On the other hand, in the state where the upper part and the lower part of the easy-open packaging bag 1 are inverted, the lower part of the housing part 4 located on the upper side is formed by the substantially semicircular arc-shaped part 4b and the oblique part 4d. Accumulation is prevented. That is, if the shape has corners on both sides of the lower part of the container 4, the powder 16 as the container may be inadvertently stored near the corners. Then, since the lower part of the accommodating part 4 is comprised including the substantially semicircular arc-shaped part 4b with a comparatively large circular arc diameter, and the hypotenuse part 4d, the powder 16 is formed in the lower part of the accommodating part 4. Is prevented from being stored carelessly.

  In the above embodiment, the front side sheet 2 and the back side sheet 3 constituting the easy-open packaging bag 1 are such that polyethylene, polypropylene, polyethylene terephthalate, polyamide, or a synthetic resin layer thereof is laminated in a plurality of layers. Further, the case where a so-called aluminum laminate sheet or the like in which aluminum is laminated on the synthetic resin layer as described above is used, but the material of the front side sheet 2 and the back side sheet 3 is not limited to this. It is also possible to use synthetic resins other than these.

Furthermore, in the said embodiment, although it was set as the structure of what was called a so-called 4-way pouch with which the upper part of the easy-open packaging bag 1 and both sides and the bottom part were sealed, it is not restricted to this, For example, upper part It is also possible to adopt a configuration called a so-called three-way pouch in which the three sides on both sides, or the upper side, one side, and the bottom side are sealed. In short, it is only necessary that the seal portion is formed so as to surround the accommodating portion 4 that accommodates the object to be accommodated. Here, in the present invention, “the housing portion 4 is surrounded by the seal portion at the peripheral portion of the easy-open packaging bag 1” is not only surrounded by the four peripheral portions but also the three peripheral portions. This includes the case of being surrounded by a part.

  In addition, the design can be arbitrarily changed within the range intended by the present invention.
