View Patent ↗This disclosure is concerned with pressure sensitive adhesive printable paper products, such as labels, and their use with various substrates, such as packaging and containers, including food containers. This disclosure is also concerned with repositionable pressure sensitive adhesive printable paper products and their transformation into semi-permanent or permanent adhesive products with respect to such substrates. This disclosure is also concerned with food and drink containers, methods of making them and their use with removable or repositionable adhesive labels. More particularly, this disclosure is concerned with containers for food or drink having chemical functionality, such as in coatings, to facilitate the use of adhesive labels with such containers.
1. A container suitable for carrying food or drink, said container comprising:
a base portion;
a plurality of walls extending from said base portion to define a receptacle portion for receiving food or drink;
said walls having inner and outer surfaces;
said inner and/or said outer surfaces being made of a material;
said container having at least one surface having a chemical functionality or bearing a coating that meets a safety standard for food contact surfaces;
said functionality or coating having an affinity for an adhesive of repositionable adhesive paper labels by enhancing the tack of such adhesives compared to the material of said inner and/or outer surfaces;
wherein said coating has an affinity for a microsphere adhesive, the coating comprising 3 to 20% by dry weight amorphous silica, and 50 to 95% by dry weight of a binder, the binder comprising acrylic, vinyl acetate, urethane or polyvinyl alcohol or an acrylonitrile or copolymer of styrene butadiene in combination with an aninoplast resin and/or an aliphatic epoxy resin.
2. The container as claimed in claim 1 , further comprising a lid portion attached to at least one of said walls.
3. The container as claimed in claim 2 , wherein said coating is applied to at least said lid portion.
4. The container as claimed in claim 1 , wherein said container is a clamshell food container.
5. The container as claimed in claim 1 , wherein said container is a fast food container.
6. The container as claimed in claim 1 , wherein said coating is applied to at least one of said outer surfaces.
7. The container as claimed in claim 1 , wherein said container is made from a paper product.
8. The container as claimed in claim 7 , wherein said container is made from a sugar cane fiber product.
9. The container as claimed in claim 1 , wherein said container is a disposable fast food container.
