[Detailed Description of the Invention] This invention relates to the structure of a bag-like container that is convenient to open and is formed by a specific combination of a container body and a lid.

In general, containers are required to meet various conditions such as processability, functionality, sealability, unsealability, hygiene, economic efficiency, etc., but this proposal specifically improves unsealability without compromising sealability. It is intended for this purpose.

Conventionally, as a means to improve the sealing performance of a container, for example, the open end of the container body is often crushed and heat-sealed in a clasped shape. On the other hand, the higher the adhesive strength, the better the sealing performance, but it is difficult to open it again.

The container body 1 is made by laminating and bonding two layers of base material and three layers of sealing material. The base material 2 is not particularly special, and may be made of paper, aluminum foil, or a combination thereof, and the sealing material 3 is also a normal material, such as polyethylene or polypropylene, which has heat sealability and airtightness. The amount of application is adjusted depending on the purpose. To make the body part 1 from a blank (paper), both ends of the blank are pasted together in an envelope-like shape, a gassho-like shape, or any other suitable form to form a cylinder, and the bottom is shaped like a round base (as shown in Figure 2). You can close it in a gassho paste form (as shown in Figure 1). In this case, of course, it is necessary to provide at least three layers of sealing material on the inner surface of the body in order to maintain the sealability or airtightness of the bottom of the container.

Like the body 1, the lid 6 also consists of seven layers of base material and eight layers of sealing material. Usually, aluminum foil is often used for the base material 7, but it is not necessarily limited to this, and the base material 7 layer itself may be made by laminating a plurality of layers, such as a sheet of aluminum foil. It is sufficient to apply the sealing material 8 only to the inner surface of the lid 6, that is, the surface that contacts the body 1, and the material thereof is assumed to have a heat-sealing temperature lower than that of the body-sealing material 3. Therefore, various combinations of the body sealing material 3 and the lid sealing material 8 are possible, but among them, the practical ones are:
For example, low pressure polyethylene (heat sealing temperature:
Approximately 140-150 ° C) -Etylene / Vinyl acetate co -coalesis (commonly known as EVA) (about 110-120 ° C), polypropylene (about 140-160 ° C) -EVA, high -pressure polyethylene (about 120-140) ℃) - Himilan (registered trademark of Mitsui Polychemical Co., Ltd., polyethylene-based copolymer containing ionic bonds) (same: approx. 100℃ or less), low-pressure polyethylene (inner body) - No coating (outer body) - There are Himilan, low pressure polyethylene-high pressure polyethylene, and others. The amount of application is appropriately determined in consideration of adhesion and peelability. The size of the lid 6 is such that it can completely cover the opening end 4, and the portion of the lid that contacts the body 1 outside the opening end 4 is a non-sealing portion 9, and a sealing material 8 is applied to this portion.
does not need to be applied.

In order to bond the lid 6 and the body 1, first the lid 6 is folded in two and is placed over the open end 4 which has been pressed into a palm-shaped shape, and then heat-sealed using a hot plate 10. The entire surface of the lid 6 is not heat-sealed, and the non-sealed portion 9 is not sealed. Of course, at this time, the lid 6 should be heated to meet the purpose of the present application.
It goes without saying that the lower limit should be the temperature and time at which the sealing material 8 melts and becomes adhesive, and the upper limit should be the temperature and time immediately before bonding the trunk inner surface sealing material 3. For example, if the body is coated with low-pressure polyethylene and the lid is coated with EVA,
If the heat sealing temperature is set to 120°C, the sealing material 8 on the lid will melt, but the sealing material 3 on the body will not melt. Therefore, the inner surface of the barrel that overlaps the seal portion of the lid remains unsealed. The specifics thereof can be appropriately determined depending on the presence or absence of the trunk outer sealing material 3, the material thereof, the material of the lid inner sealing material 8, etc., so as to be advantageous for the purpose of the present invention. It is generally preferred that the seal on the open end 4 be in a direction perpendicular to the direction of the bottom seal so that the entire container has a tetrahedral shape when the bottom is stuck together (as shown in Figure 1).

Easy to open. The body sealing material 3 does not perform any sealing function at the opening end 4, and only the sealing material 8 of the lid performs the sealing, so its sealing performance is relatively weak and it is easy to open.
Therefore, it is suitable for storing light contents or solid materials with no fluidity.

Contents can be taken out smoothly. Unlike other containers, the container of the present invention does not require the time and effort of cutting off the body seal portion or tools to open it. In addition, since there is no need to tear the body, there is no unevenness at the opening that occurs when the package is torn, and the contents can be taken out cleanly. But it has a nice texture.

The sealant 3 on the container body is applied exclusively for bonding the body and bottom, and if the inner surface of the opening end is not to be sealed as in this proposal, it is better not to apply the sealant to that part. Become. However, manufacturing a blank without partially applying the sealant or molding it into a container significantly impedes productivity. In order to avoid such a decrease in productivity, the purpose of this project is to apply the sealing material to the entire surface and not to seal the opening end, and this goal has been achieved.
