Bio-degradable food handling devices and systems and methods for making the devices. The embodiments herein relate to a bio-degradable food handling device (10, 20, 30, 40, 50 and 60) for use as at least one of a drinking straw, a stirrer, a chopstick, a balloon stick and a candy stick. Further, embodiments herein relate to systems (100) and methods (200, 300) of making the bio-degradable food handling devices (10, 20, 30, 40, 50 and 60). The bio-degradable food handling device (10) is hydrophobic and antifungal thereby increasing shelf life of bio-degradable food handling devices (10). The bio-degradable food handling device (10) is durable, hygienic, non-toxic and recyclable. The bio-degradable food handling device (10) has smooth and soft outer portion that provides comfort to user. The bio-degradable food handling device (10) can be used to draw pieces of fruit, vegetables, solid processed food pieces and other pieces of foods therethrough.

Paper products can be made from cellulose derived from corn husks. A method of making paper products may include obtaining corn husks, extracting cellulose fiber pulp from the corn husks, forming a paper sheet from the extracted cellulose fiber pulp, adding a chitosan acetic acid solution having a concentration of at least 5 wt. % chitosan to the paper sheet, forming the paper product from the paper sheet, and coating the paper product with a paraffin wax.

The present invention relates to a pressure equaliser (1) comprising:—a hollow element (101) with a cup-shaped section (1011) and a tubular section (1013) that merge seamlessly one into the other, and—a sealing element (103) that comprises a top edge (1031) with a first diameter (D1) and a central part (1033) with a second diameter (D2), wherein the top edge of the cup-shaped section (1011) of the hollow element (101) is inserted into the second inner diameter (D2) of the central part (1033) of the sealing element (103), the pressure equaliser being characterised in that at least the hollow element (101) can be disassembled into at least two hollow element parts (10a, 101b) along its longitudinal axis. The present invention further relates to a baby bottle assembly comprising: —a bottle-shaped container (3), —a pressure equaliser (1) according to the invention, —a screw element (5) and—a nipple (7a) or closure cap (7b).

A straw forming machine includes a feeding device, a pressing device, a sticking device, a conveyor device, and a cutting device. The paper material is stretched from the feeding device to the pressing device which curls the paper material. When the paper material is delivered to the sticking device, the two sides of the paper material are pressed by the sticking device to form the paper pipe, and the press roll of the sticking device rolls and sticks the two abutting portions of the paper pipe. Then, the paper pipe is delivered by the conveyor device to the cutting device which cuts the paper pipe to form drinking straws.

In embodiments, the invention includes a system, an apparatus, and a method for cleaning reusable straws. The system includes a chamber configured to contain a liquid, a siphon to drain the chamber, a transducer to deliver sonic energy to the chamber, and a plurality of straws disposed in the chamber. Each straw includes a tubular wall defining a lumen. The lumen has a length and a cross-sectional area, and the cross-sectional area is substantially constant over the length.

A drinking straw having a coating on its interior surface is disclosed. The drinking straw has a coating on its interior surface. The coating comprises an active ingredient, a film forming agent, a non-ionic surfactant, and optionally a diluent. The active ingredient may be a cannabinoid. A method of manufacturing a straw having a coating on its interior surface is also disclosed. The method comprises combining the active ingredient with a carrier, and blending to form a mixture; adding a non-ionic surfactant and a plasticizer to the mixture; agitating the mixture to form a homogeneous first dispersion; adding a film forming agent to the first dispersion and mixing until homogeneous; applying the dispersion to the interior surface of the straw; agitating the straw to cover at least part of the interior surface with the first dispersion; and drying the first dispersion inside the straw to form the coating.
