DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid enclosing bag suitable for enclosing a viscous liquid such as putty or an adhesive.

[0002]

2. Description of the Related Art Conventionally, in order to use a viscous liquid such as putty or an adhesive stored in a flexible bag such as a synthetic resin,
The bag is opened with a knife or the like, with the part to be the bag taking part facing up, and then the contents are transferred to an appropriate container with the taking part facing down before use. However, such a liquid has a very high viscosity, so that it is difficult to remove the liquid only by opening the opening of the bag downward.

[0003] For this reason, for example, Japanese Patent Application No. Hei 4-302311.
As shown in FIGS. 7 and 8, a squeezing device having a fixed-side squeezing member 42 composed of a roll and a movable-side squeezing member 41 composed of a roll that can be brought into contact with and separated from the squeezed member. 4 have been proposed. This device sandwiches the bag 6 with its lower end opened with the opening opening downward between the fixed-side squeezing member 42 and the moving-side squeezing member 41, and steps down the tread plate 43, as shown in FIG. The contents are squeezed by the two squeezing members 41 and 42 and the contents are squeezed into the container 5.

[0004]

Problems to be Solved by the Invention Japanese Patent Application No. 4-302
When the squeezing device described in No. 311 is used, the contents can be easily taken out without remaining. However, when the opening of the bag finally passes through the squeezing members 41, 42, the contents adhere to the squeezing members 41, 42, so that the contents adhered before using the squeezing device next time. Must be removed. When the contents are putty, adhesive, etc., considerable work is required to remove them.

[0005] The present invention solves the above-mentioned conventional problems, and enables a viscous liquid contained in a bag to be easily taken out without remaining, and a squeezing device as disclosed in Japanese Patent Application No. 4-302311. It is an object of the present invention to provide a liquid sealing bag in which contents do not adhere to the device even when used.

[0006]

According to the present invention, a storage bag such as a putty is cut open at a lower end of a bag filled with a viscous liquid, and the upper end is pressed with a roll to push the bag upward. A bag for pulling up and taking out the contents from the take-out part, characterized in that a protruding part is provided on the bag body side near the take-out part.

Examples of the encapsulating bag include a synthetic resin film such as polyethylene, polypropylene, nylon, and polyester, a laminate thereof, and a laminate of the above synthetic resin film or laminate and aluminum foil, woven or nonwoven fabric. What is necessary is just what has flexibility, such as a body. In the case of a laminate with a woven or nonwoven fabric, the woven or nonwoven fabric side is used outside the bag.

It is preferable to select a sealed bag having a barrier property against water vapor, oxygen and the like according to the composition of the contents. Further, the encapsulating bag may be one in which the entire periphery is heat-sealed, one in which a tubular film is heat-sealed at both ends, or a bag formed by bonding with an adhesive instead of heat sealing.

[0009] When the enclosing bag is opened, if the bag is formed by heat sealing or the like, the seal portion itself is not actually opened before sealing, and the film or the like constituting the bag is taken out near the seal portion. The part is cut by a cutter or the like and opened. The position of the protruding portion provided on the enclosing bag is a portion near the above-mentioned unsealed seal portion, that is, an outer side slightly closer to the bag body than the unsealing take-out portion. In this position, only one side of the bag may be provided, or both sides may be provided.

When the entire contents have been extruded, the protrusion is 2
The operator cannot know that the squeezing operation has been completed because the squeezing member is not passed by being blocked by the squeezing members. Therefore, the projection must have a size that does not pass between the squeezing members of the content squeezing device and a hardness that does not cause crushing between the squeezing members.

[0011] Since the viscosity of the contents of the above liquid enclosing bag is very high, when the bag is opened and passed between the squeezing members, the contents extruded by pressure spreads wider than the opening width, and this is applied to the squeezing member. Since it easily comes into contact with and becomes dirty, for example, as shown in FIGS. 1, 3, and 4
It is preferable that the shape is tapered slightly toward the part to be opened as shown in FIG.

In any of the above cases, a space for opening is left between the projection and the seal portion, and after opening, the projection is left on the bag body side. The shape of the protrusion can be rod-like, spherical or the like. In order to squeeze out the contents using the squeezing device described in Japanese Patent Application No. 4-302311, as shown in FIG.
The contents are extruded downward by sandwiching between the two rolls while pulling the bag 6 upward between the individual squeezing members 41 and 42.

[0013]

With the opening side of the opened bag taken down between the fixed side squeezed member made of a roll and the movable side squeezed member made of a roll, which can be brought into contact with and separated from the fixed side squeezed member,
When squeezing out the contents using a device that squeezes out the contents by squeezing with both squeezing members, the contents are extruded downward by clamping the bag between the two squeezing members while pulling the bag upward.

When the entire contents are extruded, the protrusion is 2
The operator cannot know that the squeezing operation has been completed because the squeezing member is not passed by being blocked by the squeezing members. Moreover, the contents such as putty stored in the bag can be easily taken out without remaining, and the contents do not adhere to the squeezing device.
