An object is to provide a food container and a paper product which are water resistant, oil resistant, and recyclable. Provided is a food container obtained by mixing and stirring water, konjac mannan, and an alkali to liberate an acetyl group to obtain modified mannan whose swelling is suppressed, releasing suppression of swelling of the modified mannan by neutralization to obtain neutral or acidic modified mannan, solating or gelating the neutral or acidic modified mannan, applying the solated mannan sol or the gelated mannan gel to a paper food container, and drying the mannan sol or the mannan gel.

Contact lens packages are provided and each includes a base member having a cavity and a sealing member coupled to the base member. An unworn contact lens is provided in a packaging solution within the sealed cavity. The base member is a thermoplastic or other recyclable material. The base member includes at least one latch and at least one slot. The latch and slot are configured to connect to the slot and latch, respectively, of another base member, after the contact lenses are removed from the cavities. A recyclable thermoplastic contact lens assembly is also provided that includes empty contact lens package base members stacked and connected together. A method to recycle used contact lens package base members, such as by curbside recycling, is also provided.

The disclosure relates to ink compositions for digital printing on an external surface of a plastic article. The ink compositions comprise an ink removal-promoting additive. In some aspects, the ink removal-promoting additive can facilitate the separation or loosening of the image from the external surface of the article when the image is exposed to a liquid-based solution at an elevated temperature. Also disclosed are recyclable plastic articles having an external surface with an image printed thereon using the disclosed ink composition and methods for removing cured ink from a plastic container. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

The invention relates to a greaseproof and waterproof packaging item comprising a composite material, the material comprising a fibre substrate and a cross-linked naturally derived polysaccharide.

The present invention discloses an eco-friendly recyclable dropper, comprising a pressing portion and a pipette, wherein a bottom of the pressing portion is wrapped around a top of the pipette, wherein a bottom inner wall of the pressing portion includes a concave groove, wherein a top outer wall of the pipette includes a corresponding convex circle, wherein the concave groove matches with the convex circle and become airtight based on the characteristics of both material, wherein the pressing portion is made of PE material, wherein the pipette is made of PP material. Since the pressing head is made of PE material or a mixture material of PE and PP, and the pipette is made of PP material, a combination of the pressing head and the pipette is better in airtightness comparing to prior arts using glass pipettes; furthermore, the design of the pressing head and the concave groove and the convex circle of the pipette provides better airtightness; the dropper and the bottle of this invention both used PP and PE material, which can be fully recycled and reused after using the liquid within, avoids environmental pollution and saves resources. The market of this invention is very wide and this invention has a breakthrough meaning in the dropper field.

A repulpable insulated container assembly having a container formed of paper such as corrugated cardboard or varying paper materials and defining an interior; and a repulpable insert placed within the interior of the container and formed of a first paper layer; and a paper fiber pad coupled to the first paper layer.

A recyclable cap for containers includes an outer body and an inner body provided with fixing means for being retained in a container, the inner body being coupled and housed inside the outer body, wherein the outer body is made of a biodegradable material of plant origin, wherein the outer body and the inner body are coupled by coupling means configured for linking the two bodies to one another, the inner body including a single-use release system configured for separating the outer body from the inner body. A user may thereby separate and recycle the outer body and the inner body in an entirely separate manner at the end of the service life thereof.

Object to be held by a user, comprising: an external structure arranged to be held by the user, a thin-walled closed bottle made of plastic comprising a body defining an internal volume and a collar,
characterized: in that the external structure is a shell in contact with at least part of the body of the bottle, and in that the shell comprises an upper collar forming an open U or C and arranged to elastically interlock on at least part of the collar of the bottle.

A cover (52) for protection of a neck (44) and a closure member (46) of a bottle (42), wherein the cover (52) comprises a sleeve (54); wherein the sleeve (54) comprises a stretchable paper material (12); wherein the sleeve (54) is configured to enclose the neck (44); and wherein the stretchability according to ISO 1924-3:2005 of the stretchable paper material (12) the sleeve (54) is at least 5% in the machine direction (MD) and at least 5% in the cross direction (CD). A bottle (42) comprising a cover (52), a method of forming a cover (52) for a bottle (42), and a method of attaching a cover (52) to a bottle (42), are also provided.

A contact lens package kit is described that includes a contact lens packages, wherein each contact lens package includes a base member having a cavity and a sealing member coupled to the base member. An unworn contact lens is provided in a packaging solution within the sealed cavity. The base member is a thermoplastic material (or other recyclable material) and includes a substantially planar surface surrounding the cavity to provide a sealing surface for the sealing member. The kit also includes at least one fastener configured to retain a plurality of base members from each of the contact lens packages after the contact lens is removed from the cavity. A recyclable thermoplastic contact lens assembly is also described, that includes empty contact lens packages attached to a fastener. A method to recycle used contact lens packages, such as curbside recycling, is further described that uses the fastener, and the fastener itself is also described.
