  • Publication number: 20220324636
    Abstract: The invention relates to the field of storage containers used for the accommodation and delivery of eggs or similar fragile items. The technical result allows the egg trays based on expanded primary and/or recycled (obtained from polyethylene terephthalate waste) polyethylene terephthalate to be recycled as many times as one sees fit. This technical result is achieved by the whole set of essential features. The essence of the invention is that an egg storage tray comprises a base having storage compartments on an inner side of the base, a lid pivotally connected to the base, and a latch configured as a hole provided in the lid and a protrusion provided on the base. The base with the latch and the lid are made of expanded polyethylene terephthalate having a density ranging from 100 kg/m3 to 900 kg/m3 and an intrinsic viscosity ranging from 0.5 dl/g to 1.0 dl/g.

  • Publication number: 20220315292
    Abstract: The utility model relates to means for closing drinking vessels, and more particularly to lids for disposable cups for hot and cold beverages. The technical result consists in devising a lid for a disposable cup that is simple to produce and can be used for the closure of hot and cold beverages, based on virgin and/or recycled (obtained from polyethylene terephthalate waste) polyethylene terephthalate foam. The essence of the utility model is that the lid for a disposable cup consists of a body with a rim for fastening to the lip of the cup, and an opening for the liquid supply, said lid being made of polyethylene terephthalate foam with a density from 100 kg/m3 to 900 kg/m3 and an inherent viscosity from 0.5 dL/g to 1.0 dL/g.

  • Publication number: 20220315314
    Abstract: The utility model relates to drinking vessels, more specifically to a disposable container for hot and cold beverages. The technical result lies in the creation of a disposable cup made of a multi-layered material based on foamed primary polyethylene terephthalate and/or secondary polyethylene terephthalate (obtained from polyethylene terephthalate waste), which is easy to produce and fit for use. The essence of the invention consists in that a disposable cup has a lateral wall, in the form of a rotation body, and a base, which are fastened to each other, wherein a flanged edge is formed in the upper part of the lateral wall, the lateral wall and the base are multi-layered and comprise a layer of foamed polyethylene terephthalate with a density of from 100 kg/m3 to 900 kg/m3 and a characteristic viscosity of from 0.5 dl/g to 1.0 dl/g, which is connected to a polyethylene layer by fusion.

  • Publication number: 20220243007
    Abstract: A polymer material consists of expanded polyethylene terephthalate with a density of 30 kg/m3 to 750 kg/m3 and an intrinsic viscosity of 0.5 dl/g to 1.0 dl/g. Polyethylene terephthalate granules with an intrinsic viscosity ranging from 0.5 dl/g to 1.0 dl/g which are produced from polyethylene terephthalate waste products or virgin polyethylene terephthalate are dried to a moisture content of 50 to 7000 ppm, then loaded into a dosing hopper of an extruder where said material is mixed with dyes or processing aids. The polyethylene terephthalate is then extruded while simultaneously feeding nitrogen or carbon dioxide or isopentane or n-pentane or freon or mixtures thereof into a connector upstream of the die. In the die and at the outlet from the die, temperature- and pressure-controllable expansion of the polyethylene terephthalate melt is carried out to a density ranging from 30 kg/m3 to 750 kg/m3.

  • Publication number: 20220242652
    Abstract: Drinking containers, more specifically to a disposable container for hot and cold beverages are disclosed. The technical result consists in the creation of a disposable cup that is simple to produce, fit for use and made of a multi-layered material based on virgin or recycled (obtained from polyethylene terephthalate waste) polyethylene terephthalate foam. The proposed disposable cup has a side wall in the form of a solid of revolution and a base that are interconnected, wherein a lip is formed in the upper portion of the side wall, and the side wall and the base are made of multiple layers and include at least one layer of polyethylene terephthalate foam with a density of 100 kg/m3 to 900 kg/m3, with a characteristic viscosity of 0.5 dl/g to 1.0 dl/g, connected by a melt with a layer of polyethylene copolymer.
