A method for coating a paper drinking straw, an apparatus for coating a paper drinking straw, and a coated drinking straw assembly are disclosed. The apparatus includes a dipping tank containing a liquid bath for coating a straw when submerged in the liquid and a straw engagement means for submerging the straw in the bath. The method includes receiving an uncoated paper drinking straw and submerging the straw in a bath containing a water-resistant and/or a water-soluble coating. The drinking straw assembly includes an elongate tubular body and a coating that has been applied to all surfaces of the straw by submerging the body in a bath containing the coating.

The present invention relates to a single use tubular straw for conditioning of a liquid passing through including; a cylindrical body for passing of the liquid; a bottom opening for inflow of the liquid in the cylindrical body; a top opening for outflow of the liquid from the cylindrical body; at least one conditioning agent for the conditioning of the liquid passing through the cylindrical body; and a seal for closing the top opening and the bottom opening of the cylindrical body. The conditioning agent is disposed on the inner surface of the cylindrical body and get dissolved in the liquid on passing of the liquid through the cylindrical body providing the conditioned liquid at the top opening of the cylindrical body.

A protective arm cover utilizes a set of curved rigid panels to create a firm, structurally-sound guard with an opening for a user's arm. A set of metal ties may be used to join adjacent panels, securing the panels end-to-end. The panels and ties may utilize sets of holes to enable connection and size adjustment, thus preventing the apparatus from consuming too much space on the bed and simultaneously ensuring that the user's arm is comfortably supported during sleep. Shifting aligned holes in the panels and ties allows for adjustment of the diameter of the arm space. An inner padding within the arm opening created by the panels ensures that the user's arm is cushioned from the rigid panels. Similarly, an outer padding prevents the user's head from contacting the panels and ties while the user rests. Thus, the apparatus may prevent damage or discomfort to an extremity during sleep.

An object is to provide a base paper for paper tubes that has lower environmental impact and is used for manufacturing of paper tubes offering excellent water resistance. As a solution, a base paper for paper tubes is provided, wherein: it has two or more but no more than five paper layers; the paper layers are bonded by a water-soluble or water-dispersible adhesive; and its elution rate is 2.0 percent or lower.

An object is to provide a paper tube offering excellent rigidity, as well as a base paper for paper tubes used for manufacturing such paper tube. As a solution, a paper tube is provided which has two or more but no more than five paper layers, whose outermost layer or innermost layer, or both, among the paper layers, has a density of 0.90 g/cm.sup.3 or higher, and whose modulus of elasticity as measured by the 3-point bending test is 2.0 GPa or higher, along with a base paper for paper tubes which has two or more but no more than five paper layers and whose outermost layer or innermost layer, or both, among the paper layers, has a density of 0.90 g/cm.sup.3 or higher.

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.

A sealable container comprising: a base having a geometric shape; sides extending from the base and defining a mouth opposite the base, wherein cross-sections of the sides parallel to the base have a geometric shape; and a seal of the mouth comprising: a first zipper member and a second zipper member, wherein when the seal is closed to seal the mouth the first and second zipper members engage each other to make the seal and when the seal is open the first and second zipper members disengage to break the seal, wherein the base, sides and seal comprise silicone, wherein the base and at least a portion of the sides adjacent the base are of sufficient thickness and rigidity for the container to freely stand vertically on its base with the mouth at the top, and wherein the seal and at least a portion of the sides defining the mouth are sufficiently flexible to allow the seal and side portion to be deformed between open and closed mouth configurations.

Spent filter media material may be blended with a classic material, such as high-density polyethylene, polypropylene, polybutylene succinate, or polylactic acid, to form a filled plastic composition. The spent filter media may include spent diatomaceous earth, spent perlite, and/or residues thereof. The composition may be performed by co-extruding a mixture of the plastic material and the spent filter media. Surprisingly, the spent filter media may be used as-supplied and without the need to dry the material. The resulting plastic composite material has numerous uses, including, for example, litter scoops and eating utensils.

A foldable drinking straw made of paper developing along a longitudinal axis, and having a flexible shaped portion configured to allow a folding, one over the other, of two adjacent portions of the straw. The flexible shaped portion is defined by a plurality of depressions, disposed in succession along the longitudinal axis, and each made on a limited circumferential portion of the circular section of the straw.

The present invention relates to a processing method for coating glass container with silicone rubber and a glass container coated with silicone rubber by the processing method. The processing method comprises: cleaning a glass container body and performing a first drying treatment; brushing or spraying a primer on a surface of a part of the glass container body, wherein the surface of the part of the glass container body is to be coated with silicone rubber; performing a second drying treatment on the glass container body, and then cooling the glass container body to a room temperature; putting the glass container body into a mold cavity of a mold, injecting the liquid silicone rubber into the mold cavity, and vulcanizing the liquid silicone rubber for 200 to 300 seconds; opening the mold and letting the mold sliding out, and taking out the glass container coated with the silicone rubber layer.
