A drip bag includes a bag main body made of a water permeable filter sheet and thin plate-like members disposed on two opposed outer surfaces of the bag main body. In the drip bag, on each of the two opposed outer surfaces of the bag main body, the thin plate-like member includes an upper bonded portion fixed to the bag main body along a top side of the bag main body, a central portion fixed to the bag main body on a bottom-side side of the bag main body relative to the upper bonded portion, and a hooking portion continuous with the central portion and disposed to be capable of being pulled out from the bag main body. The upper bonded portion has an oblique folding line obliquely intersecting a width centerline of the upper bonded portion.

Methods of sealing a woven laminated plastic bag are provided that result in no adhesive-to-adhesive contact. In various aspects the bag can be fabricated from woven polypropylene and/or polyethylene layer which can be laminated with a film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.

A carton for holding at least one article. The carton has a plurality of panels that extends at least partially around an interior of the carton. A plurality of end flaps are respectively foldably connected to a respective panel of the plurality of panels for closing an end of the carton. An engagement structure is attached to at least one panel of the plurality of panels. The engagement structure is positioned for receiving the at least one article and activating the at least one article.

A container is provided that includes a container body and a lid member, the container body and the lid member being sealed by an annular seal portion. There is provided a detaching seal portion which is detached in response to increase of pressure inside the container body associated with deformation of the container body. The annular seal portion is formed by a pressing operation of pressing the lid member against the flange via a seal bar having at its leading end an annular projection having a shape corresponding to the annular seal portion, a groove-like sunk portion corresponding to the annular projection being formed in the flange by the pressing operation. At least a portion of the sunk portion formed in the detaching seal portion comprises an uneven groove having a cross sectional shape with a smaller curvature radius on its radial inner side than its radial outer side.

Provided is a portion container whose detaching seal portion can be easily detached by a stress applied from a radial inner side based on an inside pressure of a container body, but can be hardly detached by a stress applied from the outside during distribution. Provided also are a seal head for sealing such container and a container sealed with using such seal head. The seal head includes pressing end portions for pressing a lid member against a flange of an opening. At least a portion of the pressing end portions is formed as an uneven projecting portion having different curvature radii in its cross sectional contour between a radial inner portion and a radial outer portion of the opening.
