Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container filled with a fluid such as a beverage such as juice or a cleaning liquid.

[0002]

[Prior Art]

For example, as a container filled with a fluid such as a beverage such as juice or a cleaning liquid, as shown in FIG. 8, the inner dimension m ₁ on the upper side and the inner dimension m ₂ on the lower side are the same. A container 22 constructed by heat-sealing the peripheral portion has been widely used.

By the way, in this type of container, since liquid overflow easily occurs when the upper end side is opened, as shown in FIG. 9, the inner dimension m ₁ on the upper side is smaller than the inner dimension m ₂ on the lower side. A container 24 constituted by heat-sealing the peripheral portion of the sheet 23 is proposed (Japanese Utility Model Laid-Open No. 57-110039).

[0004]

[Problems to be solved by the device]

 However, in the case of the proposal of FIG. 9, even if the upper end side is broken and opened due to the action (surface tension) of the filled fluid, the mouth does not spread easily, that is, it seems that the mouth is opened. Therefore, there is a fatal drawback that it is difficult to pour the filled material into the outer container. In particular, the higher the viscosity of the filling material and the smaller the filling volume compared to the internal volume, the more natural opening of the mouth cannot be expected even if the upper end side is torn and opened. Difficult to pour what is in the outer container. In addition, since the mouth is difficult to open naturally, the filler is often spilled, which is not preferable to the type 8 container.

Therefore, an object of the present invention is to provide a container in which the opening can be expected to expand naturally when the upper end is broken and opened.

[0006]

[Means for solving the problem]

 The object of the present invention is a container comprising a bag-shaped portion filled with a fluid by sealing the end portion of the sheet material, the sheet material in a state in which the fluid is unfilled and not inflated. This is achieved by a container characterized in that the sheet material is sealed such that the inner dimension between the right and left sides of the sheet is substantially longer from the grip portion to the upper end portion toward the upper end portion.

It should be noted that the seal line formed by sealing the sheet material is configured so that there is no inflection point so that the inner dimension between the left and right sides of the sheet material becomes substantially longer from the grip portion to the upper end portion toward the upper end portion. It is preferable that the sheet material is formed with a concave portion for gripping in a substantially middle portion in the vertical direction of the sheet material.

[0008]

[Action]

 When the container configured as described above is opened by breaking the upper end, the direction of action of the force from the gripping force on the sheet material is in the direction of the outward expansion, and therefore the natural expansion of the opening part occurs. The feature is that it can be expected and it is easy to pour the filled material into the outer container. If the inner dimension between the left and right from the approximate grip to the upper end does not become longer toward the upper end, for example, not only from the approximate grip to the upper end, but only near the approximate upper end or In the case of only the vicinity of the part, the natural expansion of the opening as in the present invention cannot be expected, and therefore the condition that the inner dimension between the left and right from the grip to the upper end is longer toward the upper end is not satisfied. It has to be done. It is sufficient that this condition is satisfied, and therefore the lower end side may be one in which the inner dimension between the left and right does not change. However, it is preferable to seal the inner dimension between the left and right parts in order from the lower end to the approximate grip. That is, a container in which the sheet material is sealed so that the inner dimension between the left and right of the sheet material becomes longer from the lower end portion to the upper end portion as it goes to the upper end portion, particularly, the sheet material is sealed so that there is no inflection point in the side seal line is preferable. It is a thing.

Incidentally, when the filling amount is a small amount such as 40% or less of the internal volume, there is almost no sticking and closing of the opening (no natural spread of the mouth), which is conventionally recognized, and the filling work is extremely difficult. It was easy. Even if a recess for gripping is formed in a substantially middle portion of the sheet material in the vertical direction, the inner dimension between the right and left from the substantially gripping portion to the upper end is sealed so that the inner dimension becomes longer toward the upper end. If so, it is easy to form the holding recess, that is, it is not necessary to make the shape of the sheet material for forming the holding recess complicated.

That is, the container of the present invention can be provided with a structure in which the natural expansion of the opening can be expected and the structure is easy to grasp.
