Abstract

(57) [Summary] [Purpose] To facilitate the operation of refilling liquid contents from a bag into a refill container easily and simply. [Structure] A packaging bag formed with a spout has a structure in which a guide sheet including at least the position of the spout is integrally bonded to one side or both sides of the bag.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a packaging bag used when injecting liquid contents into a refill container after opening.

[0002]

[Prior art]

 Conventional methods used to open a synthetic resin sealed bag and transfer the liquid contents to a refill container include, for example, setting a funnel on the container side and cutting the corners of the bag into triangles. There is a method of using a valve that also serves as a spout, and a method of forming a spout at the time of opening by providing a jetty seal portion on the bag as in Japanese Patent Application No. 54-45900.

[0003]

[Problems to be solved by the device]

 These have the following drawbacks. For example, none of the methods is reliable or easy depending on changes in various conditions such as the concentration of liquid contents and the diameter of the container. The present invention has been made in view of the above drawbacks, and is a packaging bag with a spout guide that can be carried out very easily, conveniently and reliably and at a low cost in the work of opening the packaging bag and transferring the contents to a refill container. The purpose is to provide.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has a structure in which a resin sheet is bonded to one side or both sides of a packaging bag in which a spout is formed and is integrated.

[0005]

[Action]

 According to the above configuration, when the packaging bag is opened and the contents such as liquid are transferred to the refill container, the spout of the packaging bag can be inserted into the refill container, and one of the cases. The valve function makes it possible to work reliably and easily without leakage.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. Embodiment 1 FIG. 1 is a perspective view of a bag which is an embodiment of the present invention, in which 1 is a bag, 2 is a spout, 3 is a seal opening, 4 is an opening notch, and 5 is a guide sheet. In this embodiment, in a packaging bag provided with a spout, a guide sheet is bonded and integrated at the spout position. The guide sheet is attached to one surface of the film in this embodiment. This time, the material used was a polyethylene terephthalate resin or polystyrene resin sheet with a thickness of about 0.1 mm. Also, the guide sheets can be provided on both sides depending on the viscosity of the contents and the handling conditions. FIG. 2 shows a cross section taken along the line AA in FIG. Reference numeral 5 is a guide sheet, 6 is a film, 7 is an adhesive layer, and 8 is a seal portion. A guide sheet 5 is attached to one surface of the film 6 by an adhesive layer 7, and the other film 6 is sealed to form a bag. When the guide sheet 5 is attached to the film surface of the spout, the film surface is stretched with a certain rigidity to generate tension, which acts as a force to close the spout 2 and serves as a kind of valve. is there. Therefore, for example, even if liquid contents such as detergent after opening are still left in the packaging bag, they will not leak even if they are laid down or inverted. Therefore, the work of injecting the refill container from the packaging bag of the present invention can be easily performed without spilling without much care. It is also possible to use degradable plastics as a material, which are compatible with environmental problems. Embodiment 2 FIG. 3 is a perspective view of a bag according to another embodiment of the present invention, in which 1 is a bag, 2 is a spout, 3 is a seal opening, 4 is an opening notch, and 5 is a guide sheet. In contrast to the first embodiment, the spout is arranged at the outer side position. For this reason, bag-making work is facilitated, resulting in cost reduction. In this way, the spout can be formed at any position. The size and shape of the spout are determined by the relationship between the viscosity of the content and the pressure applied during pouring. Embodiment 3 FIG. 4 is a perspective view showing another embodiment of the present invention, in which 1 is a bag, 2 is a spout, 3 is a seal opening, 4 is an opening notch, and 5 is a guide sheet. The spout 2 is provided with an inclination in the direction of the mouth, the width at the tip is made small, and the width at the base is made large so that the spout can be easily inserted into the container and liquid spillage can be prevented. It is also possible to cut the spout later according to the diameter of the container. In this embodiment, the injection amount can be controlled from a fairly small amount. Embodiment 4 FIG. 5 is a perspective view showing another embodiment of the present invention, in which 1 is a bag, 2 is a spout, 3 is a seal opening, 4 is an opening notch, and 5 is a guide sheet. It is characterized in that the guide sheet 5 is formed on the entire upper side of the bag. In a normal bag, since it has a coreless flexible structure, it becomes unstable and soft when the content volume becomes small, making it difficult to inject.However, in this example, the bag is in a tightly tensioned state and easily moved to the end. Can be changed.

[0007]

[Effect of device]

 According to the present invention, it is possible to easily and simply carry out the operation of relocating the refill container. That is, since the guide sheet is attached to the spout, it can be easily inserted into the filling port of the refill container, and tension is applied to the film at the spout to cause the spout to close with a certain force. . Therefore, it acts as a kind of valve, and the contents cannot come out without applying a certain pressure or more. As described above, the present invention can achieve the effects of the rigidity of the spout and the valve function of the spout to facilitate pouring and pouring with a simple and simple structure. Therefore, if you accidentally knock it down or upside down, it will not spill. In addition, it is possible to use half of them and leave them, which increases the degree of freedom in use and improves usability. The contents can also be applied to surface active agents such as detergents and highly viscous liquids. Further, the present invention contributes to resource saving and environmental conservation because it provides a packaging bag rather than using a disposable container as a refill container. Furthermore, degradable plastics can be used for this, which can contribute to further environmental conservation.
