いられている。2. Description of the Related Art There are several types of containers formed by stacking a lid on a container body and heat-sealing the periphery. Among them, a bag-shaped container formed by two thin sheet materials is In order to make it possible to easily open the bag, it has been conventionally practiced to provide a notch in the seal portion and tear the bag at the position of the notch. In the bag-shaped container, as described in Japanese Utility Model Laid-Open No. 1-116153, a part of the sealing portion of the packaging bag is in a range where the non-sealing portion communicating with the content storage portion does not reach the outer end of the sealing portion. It is also known that the seal portion is provided with a notch and a notch is provided in the seal portion so as to face the non-seal portion, and the notch is used to tear. However,
These opening means are effective and highly convenient for a bag-shaped container formed entirely of a thin sheet material, but at least a certain thickness of the container main body is required, for example, in the case of skin pack packaging of sliced bacon. In the case of a container formed of a rigid sheet material, it may be difficult to tear using the above-mentioned notch. Therefore, for example, as a container for slicing bacon packaging, it is often used that put the contents in a styrene foam deep dish container and cover with a wrap, and also put the contents on a thick mount. In the case of a container that covers the periphery with a sheet material and heat seals, or a container that puts the contents in a skin pack packaging or a deep drawing package and covers the periphery with a sheet material and heat seals the periphery, for example, Part of the non-sealed portion is provided with an opening means for peeling the lid material from the position of the non-sealed portion. In addition, for coffee milk potion packs, etc., the container body is made of a hard plastic product, part of its sealing flange is bulged outward, and a notch is made in the tip of the container body to fold it together with the lid material. The one that is designed to be peeled off is used.

限定される。[Problems to be Solved by the Invention] A package using a container of a type in which contents such as sliced bacon are placed on a thick mount or placed in a skin pack package or a deep drawing package and a sheet material is covered to heat seal the periphery. In this case, in order to allow the package to be opened easily by hand, for example, as described above, it is known that the outer edge of the container corner part is partially unsealed and the lid is peeled off from the unsealed part. However, it is difficult to open the lid by picking up the lid away from the mount or the package at the unsealed portion, and it is not so easy to open. It is also possible to fold the tip of the container body molded from hard plastic like the above-mentioned potion pack and peel it off together with the lid material, but such a material has a high material cost and cannot be packaged in a skin pack. Therefore, it is not suitable for packaging such as sliced bacon, and its use is limited.

The structure is such that a sheet material provided with a seal layer on one side is sealed inside the seal layers. And a container formed by heat-sealing the periphery so that one is a container main body and the other is a lid member, and a container part is provided with a seal part around the container. A non-sealing portion is formed in such a manner as to be separated from the inner circumference of the sealing portion and leave the sealing portion on at least a part of the outer circumferential side, and at a position passing through the non-sealing portion of the container body, inside the sealing portion of the container body. It is characterized in that a non-sealing portion continuous with the peripheral side is provided with a notch for separating from the outer peripheral side as an opening knob having a predetermined shape. Here, it is assumed that the container has, for example, a substantially rectangular shape in a plan view, and a non-sealing portion is set at a corner portion. Then, in that case, for example, the non-sealing portion is a substantially isosceles triangle having two sides substantially parallel to the two sides of the corner portion of the container, and the notch is substantially at the bottom of the substantially isosceles triangle in the portion passing through the sealing portion. The portion that is parallel and passes through the non-sealing portion has a shape curved toward the apex side of the substantially isosceles triangle. In addition, the non-sealing portion is set on the outer peripheral side of the corner portion of the container in a band shape in parallel with the bottom side of the substantially isosceles triangle so as to leave a sealing portion of a substantially isosceles triangle that is substantially parallel to the two sides of the corner portion, and is cut. May be provided in a straight line substantially parallel to the base of the substantially isosceles triangle so as to pass through the non-sealing portion slightly outside the base.
