Abstract

(57) [Summary] [Purpose] It is possible to dispense the powder, granular or liquid contents even if one side of the package is opened. [Structure] In a packaging bag 1 whose inner surface is formed of a flexible packaging material having heat-sealing properties, a partially sealed adhesive portion 7 is formed in an area closer to the inside of one side to be opened. Since there is a gap between the adhesive parts 7, even if one side of the packaging bag 1 is torn by the opening notch 8, the contents can be dispensed from this gap.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is suitable for packaging bags for storing fluid contents such as powder, granular materials and liquid materials. It is related to

0002

[Conventional technology]

Conventionally, three-sided sealed bags and four-sided sealed bags have been used to package various products including food. BACKGROUND ART Various types of packaging bags, such as plastic bags, are widely used. And this one For example, an eel packaging bag can be opened from the opening notch formed in the seal on one side. The package is opened by tearing the top end horizontally.

0003

[Problem that the idea aims to solve]

Conventional packaging bags are opened by tearing the top end horizontally, as described above. Since the opening is wide open, it is especially difficult to prevent the flow of powder, granular materials, liquids, etc. It is difficult to dispense the contents of packaging bags containing dynamic contents. There was a problem. In other words, when you tilt the packaging bag to take it out after opening, If you are not careful, you may end up spilling out too much of the contents. Also, a little It is possible to make the opening smaller by tearing only It is difficult to do this reliably by hand.

0004 This invention was made in view of the above problems, and its purpose is to For packaging bags containing powder, granular or liquid materials, even if one side of the bag is opened, the contents will not remain intact. Our goal is to provide packaging bags that are easy to dispense.

[0005]

[Means to solve the problem]

In order to achieve the above object, the present invention uses a flexible packaging material whose inner surface has thermal adhesive properties. In a packaging bag formed by It is characterized by forming a bonded part that is rolled.

[0006]

[Effect]

In the packaging bag with the above structure, there is a gap between the partially sealed adhesive parts. is formed. After opening, the contents are dispensed from this gap.

[0007]

【Example】

FIG. 1 is a plan view showing a packaging bag as an embodiment of the present invention. This packaging bag 1 is , two pieces of film-like packaging material with heat-sealable inner surfaces are put together, and the surrounding area is heat-sealed. It is made by forming the left and right seal parts 2, 3 and the upper and lower seal parts 4, 5. A known occlusal device 6 is attached to the upper inner surface over the entire width. Furthermore, a partially sealed adhesive part 7 is provided below the articulating tool 6. It is being In addition, the left seal part 2 is located between the upper seal part 4 and the articulating tool 6. An unsealing notch 8 is formed in such a manner that

[0008] In this example, polyester film (outer layer) and polyethylene are used as packaging materials. A composite film is used in which the film (inner layer) is laminated by dry lamination. It is. Further, the articulating tool 6 is composed of a convex member and a concave member made of polyethylene. Both members are applied to the inner surfaces of the two packaging materials in advance when they are in their original state. Each is bonded by heat fusion. Then, so that both members of the articulation tool 6 are aligned, The two packaging materials are stacked together, and the vertical sealing parts 2 and 3 are heat-sealed. After that, the upper seal part 4 and adhesive part 7 are heat-sealed, and then the contents are sealed. After filling with granular salt, the lower seal part 5 is heat-sealed. A packaging bag 1 is formed.

[0009] The packaging bag 1 having the above structure is made by pulling the upper part of the bag laterally from the opening notch 8. Opened by tearing. After opening, by tilting and shaking the packaging bag 1, , granular salt is dispensed from the gap in the partially sealed adhesive part 7 .

0010 The above-mentioned packaging bag 1 contains the above-mentioned salt, other powders such as sesame seeds, furikake, etc., or It stores liquid substances such as sauce, soy sauce, and mayonnaise. stop By selecting the size and arrangement of the adhesive part 7 according to the size and viscosity of the contents. The amount dispensed is adjusted.

[0011] In the above example, polyester film and polyethylene film were used as packaging materials. Although we have shown an example using a composite film consisting of It can be applied to bags using any packaging material, depending on the relationship with the contents. be. In addition, in order to provide directionality when opening by tearing, stretched film is stacked. It may be layered. Note that the articulating tool 6 shown in the above embodiment is not necessarily necessary. It's not a thing.

0012 In addition to the four-sided sealed bag as shown in the above embodiment, the present invention also provides a three-sided sealed bag. Needless to say, the present invention can also be applied to a self-supporting bag or the like. In particular, free-standing When applied to bags, it is easy to use. For example, with an articulator If it is applied to a free-standing bag and contains salt, etc., it can be stored as is without changing it to a container such as a small bottle. It can be used at the dining table. Also, if liquid is added, the adhesive area The contents may ooze out from the gaps in the bag, but if you use a free-standing bag, this can be avoided. Things like this can be prevented.

[0013] Also, to open the packaging bag, tear it from the opening notch as in the above example. Alternatively, you can use scissors or a cutter, or insert a cut tape. is also possible.

[0014]

[Effect of the idea]

As explained above, the present invention is made of a flexible packaging material whose inner surface has heat-fusible properties. A partially sealed packaging bag is placed on the inner side of one side to be opened. Since there is a gap between the adhesive parts, one side is Even if the package is torn and opened, the contents of powder, granular or liquid materials can be dispensed through this gap. be able to.

[0015] In addition, rather than selecting the size and arrangement of the adhesive part appropriately, it is possible to dispense the contents according to the contents. The amount can be adjusted.

[0016] Additionally, the adhesive part can be formed at the same time as sealing in the conventional bag making process. Therefore, the packaging bag of the present invention can be manufactured easily and at low cost.
