Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a bag.

[0002]

2. Description of the Related Art As described in Japanese Utility Model Application Laid-Open No. 4-35538, there is a bag in which a handle is provided at an outer edge seal portion of a body sheet on the front and back of the bag.

[0003]

When the content liquid is poured out,
The body sheets on the front and back overlap each other to close the spout, impairing the pourability. Even if the spout is open at the start of the pouring with a large flow rate, it is easy to close at the end of the pouring with a small flow rate.

[0004] Even if a rigid spout tube is attached to the spout of the bag, the front and back trunk sheets may overlap each other and close the spout before the spout tube.

An object of the present invention is to improve the pourability of a bag.

[0006]

According to a first aspect of the present invention, there is provided a bag according to the present invention, wherein at least one end of a handle is attached near a spout of a body sheet of the bag.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a flexible self-supporting bag 10 is formed by joining the upper and side edges of body sheets 11, 12 (not shown) on the front and back by heat fusion or the like. Upper edge joint 11
A, forming the side edge joints 11B, 11B, and joining the peripheral edge of the bottom sheet 13 to the lower edges of both body sheets 11, 12 by heat fusion or the like to form a bottom edge joint 11C. And at least three sheets. In addition, bag 1
0, the upper edge joint portion 11A is formed into a mountain shape, the central portion in the width direction is set as a spout forming portion 14, and when the upper edge joint portion 11A is cut along the cut line A, the spout 15 is formed in the spout forming portion 14. It can be formed. In the bag 10, the contents liquid is filled in the above-mentioned joining process of the body sheets 11, 12 and the bottom sheet 13.

The bag 10 has the handle 20 mounted near the spout 15 on the front body sheet 11 so that the longitudinal direction of the handle 20 is oriented in the same direction as the direction away from the spout 15. The handle 20 is provided along the longitudinal direction of the central portion in the width direction of the bag 10, and is attached to the body sheet 11 by bonding both end joints 20 </ b> A and 20 </ b> B. Handle 2
No. 0 can be constituted by an adhesive tape provided with an adhesive surface on both end joints 20A and 20B.

The bag 10 may be provided with a rigid spouting tube (spout) at the spout forming portion 14 of the upper edge joint portion 11A.

The bag 10 has a liquid volume of, for example, 500 mL to 2500 m.
L, a surfactant having a viscosity of 2 to 200 mPa · s (30 ° C.) and a specific gravity of 0.9 to 1.1 is used as the content liquid.

According to this embodiment, the following operations are provided. (Action According to Claim 1) As shown in FIG. 2, at the time of pouring out the content liquid, the handle 20 is lifted, thereby pulling the front body sheet 11 on which the handle 20 is attached, upward, and the back body. The outer sheet 12 bends downward due to the weight of the content liquid, and the front and back trunk sheets 11 and 12 near the spout 15 overlap each other without closing the spout 15, but are separated from each other and the spout 15 is widely opened. In addition, the pourability can be improved, and the refillability of the refill container can be improved.

When the front and back torso sheets 11 and 12 are made of a sheet material having a strong stiffness (tensile elastic modulus), the flatness of the torso sheets 11 and 12 is large and the spout 15 is large.
Is easily blocked, so that the effect of the present invention for improving the pourability is remarkable. For sheets of the same material, the stiffness is said to be proportional to the cube of the thickness of the sheet.

As a strong sheet material, (1) P
ET12μm / ONY15μm / OPP20μm / LLDPE130
μm, (2) ONY15μm / ONY15μm / LLDPE130
μm / or (3) ONY25μm / LLDPE180μm (However, PET is polyethylene terephthalate, ONY is directional nylon, OPP is directional polypropylene, LLD
PE is a linear low-density polyethylene, and a numerical value (μm) indicates a wall thickness). As a general sheet material, there is, for example, ONY 15 μm / LLDPE 130 μm in which the thickness of each of ONY and LLDPE described in (3) above is reduced.

(Operation Corresponding to Claim 2) By providing the handle 20 at the center of the bag 10 in the width direction, the pouring posture of the bag 10 can be stabilized, and the opening area of the spout 15 can be made larger.

(Functions Corresponding to Claim 4) The joints 20A and 20B at both ends of the handle 20 are
1 (FIG. 1), the entire bag 10 can be lifted with only one hand, and the spout 15 can be widely opened as described above. However, the handle 20 is a one-end joint 20
Only A may be attached to the trunk sheet 11 (FIG. 3). In addition, when the handle 20 is provided with a tapered shape that becomes wider as approaching the spout 15 to the joint 20A near the spout 15, the above-described effect of improving the pourability can be further improved.

(Effect corresponding to Claim 5) By providing a rigid spouting pipe in the spout forming section 14 of the bag 10, the front and back trunk sheets 11, 12 in front of the spouting pipe are provided.
Can smoothly discharge the content liquid from the discharge pipe under the condition that the liquid is more widely opened.

(Action corresponding to claim 6) When the content liquid is composed of a surfactant, the surfactant is easier to wet the body sheets 11 and 12 than water.
When the block 5 is closed, the surfactant is easily transmitted from the spout 15 to the outer surfaces of the body sheets 11 and 12, and furthermore, the bag 10 is easily stained and dripped, but in the present embodiment, the spout 15 is Since the blockage is avoided, dirt and liquid dripping of the bag 10 using the content liquid as the surfactant can be improved.

The flexible self-supporting bag 30 of FIG. 4 is substantially different from the flexible self-standing bag 10 of FIG.
When attaching to the body sheet 11, the knob 33 formed at the free end of the handle 31 is arranged closer to the spout 15 than the joint 32. The knob 33 has an uneven surface and is hard to slip.

The flexible self-standing bag 40 shown in FIG. 5 is substantially different from the flexible self-standing bag 10 shown in FIG.
The outer edge portion 42A of the joint portion 42 near the spout 15 is formed in a concave shape when the sheet is attached to the body sheet 11.
The knob 43 of the handle 41 is arranged on the opposite side of the spout 15 with the joint 42 interposed therebetween, and has a finger insertion cut line 43A. When the handle 41 is lifted, the concave outer edge 42A of the joint 42 positively lifts the trunk sheet 11 in the vicinity of the spout 15 so as to open the spout 15 more widely, thereby improving the pourability.

The flexible self-supporting bag 50 of FIG. 6 is substantially different from the flexible self-supporting bag 10 of FIG.
The outer edge portion 52 </ b> A of the joint portion 52 near the spout 15 is formed in a concave shape.
The knob 53 of the handle 51 is connected to the spout 1 from the joint 52.
It is disposed closer to the fifth and has a finger insertion hole 53A. Handle 5
1, the concave outer edge 52 </ b> A of the joint 52 positively lifts the trunk sheet 11 in the vicinity of the spout 15 to protrude the spout 15 more widely, thereby improving the pourability.

(Action corresponding to claim 3) Handles 41, 5
Joints 42, 52 for attaching one end of the first to the body sheet 11
By making the outer edges 42A and 52A near the spout 15 concave, the spout 15 is not blocked and the spout 15
Can be opened to improve pourability.
