あった。2. Description of the Related Art Conventionally, a package having a peelable welded portion at its periphery has been widely used as a molded container sealed with a lid or a packaging bag for medical equipment such as a syringe, stationery, various foods, and the like. I have. Normally, such a package or molded container is formed by molding the container body with a thermoplastic sheet, storing the contents in the contents storage section, and covering the content with a lid film having the thermoplastic resin layer as the innermost layer, Welding is performed so that the container body sheet and the lid film can be peeled off, and a peeling start portion is formed. By the way, when the above-mentioned package is peeled and opened from the peeling start portion, there is a problem that it takes time to open the package if the hands are wet or gloves are worn. In order to solve such a problem, in recent years, it has been studied to use a tear-opening start portion that can be opened by tearing in addition to the peeling start portion. Even when the package body provided with such two opening means is opened, the lid film is peeled from the peeling start portion and opened because the opening by the peeling is reliable and dust is not easily scattered. It is often used. However, at the time of peeling and opening, since there is a tear opening start portion for tear opening, the lid film is torn in the direction of the content storage section from the tip of the tear opening start portion, and the base film is torn off in the middle and taken out. However, there has been a problem that the width of the product becomes narrow and it is difficult to take out the contents.

が安全である。[0007] The sheet of the container body and the lid film are provided with, for example, a peeling start portion formed of an unwelded portion, and the peripheral edges are heat-welded. The welded portion is peelable, and its width varies depending on the size of the contents, but is usually about 1 to 20 mm. The welding may be single or plural. In addition, the strength of welding between the lid and the main body at that time was 1 to 10 when measured based on a bag heat seal strength test described in JIS Z-0238.
It is desirable to be 25 N / 15 mm. The tear-opening start portion may be provided at any part of the package, but is preferably provided above the contents storage section like a normal tear-open package. The shape of the tear opening start portion is not particularly limited, but is preferably a linear cut. Usually, when forming a tear-opening start portion of this kind of tear-open package on a bag making machine or an automatic filling machine,
A method of forming a tear-opening start portion at an intermediate portion between two adjacent packages and then separating the two from almost the middle portion of the tear-opening start portion is adopted because it is efficient. In the present invention as well, this method is often employed. Therefore, it is preferable that the tear-opening start portion of the package of the present invention is provided on both sides of the package. And when forming a tear opening start part in this way, it is good to make a tear opening start part orthogonal to a separation line so that a separation line may shift a little when it separates into two bodies. . Since the separation line forms the side end of the package, in the present invention, the opening start portion is preferably orthogonal to the side end of the package. And, in the package of the present invention, the tip of the tear opening start portion is deflected toward the peeling start portion, and / or an unwelded region is provided in the welded portion, and the tear opening start portion is provided in the unwelded region. Exists. Since the tip of the tear opening start portion is deflected in the direction of the peeling start portion, when the lid film is peeled from the peeling start portion, the welded portion is peeled without breaking the lid film, and the lid film is required. Can be peeled off over its length. In addition, since the unwelded region is provided in the welded portion and the tear opening start portion is accommodated in the region, the tearing force does not propagate to the tear opening start portion when peeling and opening.
Accordingly, similarly, the welded portion can be peeled off and opened without breaking the lid film. At this time, the tip of the tear opening start portion may not be deflected in the direction of the peeling start portion, but a slight shift occurs at the time of forming the tear opening start portion, and the tear start portion reaches the welded portion. It is safer to deflect in the direction of the tearing start portion, since there is a possibility that the tearing will occur.

である。Test Example An evaluation test was performed on the influence of the tear opening portion on the peeling and opening. As a sample used, the container body sheet was made of low-density polyethylene 45 μm / ionomer 60 μm.
A three-layer film of m / low density polyethylene 45 μm was used, and a polyester film 12 μm / polyethylene 15 μm / polyethylene / polypropylene mixed easy peel sealant 30 μm was used as a lid film. The ionomer was used to make it easier to tear. Both were welded by an impulse sealer. The seal strength was about 5 N / 15 mm. The sample used was 50 mm x 150 mm in size and the welding width was 10 mm.
mm. The peel-opening start portion was formed with the unwelded portion up to 15 mm from the tip of the sample, and the position of the tear-opening start portion was 60 mm from the tip. If the shape of the tear opening part is a straight line, if it is a straight line perpendicular to the side end, if it is a straight line deflected toward the tip of the welded part, and provide an unwelded area in the welded part,
The peeling and opening test was performed from the tip of the welded portion for the three types in the case where the region was linearly deflected toward the tip of the welded portion in the region. (See FIG. 5) The following results were obtained when the number of times the lid film was torn was shown. In conclusion, when the tear opening start portion is a linear notch, the lid film is peeled without being broken by directing the notch toward the tip of the welded portion and providing the notch portion in the unwelded region. Providing the notch in the unwelded area and directing the direction toward the tip of the welded portion, that is, the peeling start portion, is effective for peeling without breaking the lid film.

By deflecting in the direction, the welded portion can be peeled off without breaking the lid film and the lid film can be peeled over a required length, so that it is easy to take out the contents. Further, since the unwelded region is provided in the welded portion and the tear opening start portion is accommodated in the unwelded region, the tearing force does not propagate to the tear opening start portion when peeling and opening. Accordingly, similarly, the welded portion can be peeled off and opened without breaking the lid film. In addition,
When an unwelded area is provided, the same effect is obtained even if the tip of the tear opening start portion is not deflected in the direction of the peeling start portion. Since the portion may reach the welded portion, the effect can be further ensured by deflecting in the direction of the tearing start portion.
