The present invention relates to a packing container using a coconut by-product, a grain by-product, or a coffee by-product, and a method for producing same. A paper packing container produced according to the present invention enables a packing container shape to be in a complete form by adjusting the moisture content of pulp of a coconut by-product, a grain by-product, or a coffee by-product, which is an eco-friendly raw material, before entering a molding process.

A lid for covering a cup-shaped drinking container, a resin forming the lid being a biodegradable resin, 50% by mass or more of the biodegradable resin having a deflection temperature under load of 80° C. or more, 5% by mass or more of the biodegradable resin having a flexural elastic modulus of 3000 MPa or more.

Embodiments are directed to improving transportation of tubular structures. A roller may have a housing having a vertical axis and one or more upper flanges. The one or more upper flanges may have an upper surface that is transverse and non-perpendicular to the vertical axis of the housing. Optionally, the upper surface may be curved. The roller may have one or more wheels that are rotatably coupled to the housing and that extend downward from the housing.

A folding lid is presented for covering a container opening made from a recyclable material. The folding lid includes: a base element, an accommodating opening, which is formed in the base element and configured to accommodate a container for an item to be packaged in such a manner that a container opening of the container is arranged in the region of the accommodating opening, and at least three wing elements, which are integrally formed onto the base element circumferentially via a respective folding region along an outer edge of the base element with respect to the accommodating opening; wherein the at least three wing elements can each be pivoted between an open position, in which the accommodating opening is cleared, and a closed position, in which the at least three wing elements cover the accommodating opening completely, wherein adjacent wing elements of the at least three wing elements at least partially overlap in the closed position.

An anti-siphon device configured to be used within the fuel filler pipe of a heating oil fuel tank, the device having a rigid body member that fits within an intermediate section of the fuel filler pipe and a restriction element having apertures allowing fuel but not a siphon hose to pass through; and a method of installing the anti-siphon device in a fuel filler pipe.

A collapsible article comprising a plurality of foldably interconnected foldable sections/modules. The foldable sections can be part of cylindrical or conical surfaces. They can also be in the form of closing sections. When the foldable sections are part of tubular surfaces, either cylindrical or conical, they consist of four polygonal surface segments. The polygonal segments are curved/round in unfolded state and have a flat or approximately flat shape in partly folded and folded states. The folding process usually involves an abrupt transition between the unfolded and folded positions which makes the unfolded article almost as stable as non-foldable equivalents. The folding process usually requires application of force on the edges that form valley creases during folding.

The present invention describes a method for producing a leak-tight vessel for holding a gas and/or liquid, comprising the steps of winding a heat-sealable thermoplastic barrier strip around a removable mandrel in such a way that each strip fragment overlaps with a substantially parallel strip fragment over at least a lateral overlapping distance, consolidating the overlapping strip fragments so as to form a gas and/or liquid tight layer, winding a fibrous material around the gas and/or liquid tight layer, thereby leaving an opening large enough for removing the mandrel. The invention also describes a leak-tight vessel produced in this way.
