The present inventors conducted intensive studies for solving the problems. As a result, they found a heat-sealable polyester resin which can be used for food application and which exhibits excellent adhesiveness to various containers made of polystylene, polyvinyl chloride, A-PET (amorphous polyethylene terephthalate) , or polypropylene, each having different property.

The aim of the present invention is to provide a polyester resin which exhibits excellent adhesiveness to various substrates such as polystylene, polyvinyl chloride, or A-PET.

According to the present invention, there is provided a polyester resin containing a polycarboxylic acid component and a polyhydric alcohol component as constitution units, wherein, when the total amount of the polyhydric alcohol component is taken as 100 mol%, the content of diethylene glycol component is 60 mol% or more, and wherein the glass transition temperature of the polyester resin is 20° C. or lower.

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.

A container forming apparatus includes a plurality of forming members that have outer forming surfaces, which are shaped to form pockets in a sheet of material. A plurality of actuators are in mechanical connection with the forming members. The actuators are able to extend and retract the forming members. A controller is in electrical communication with the plurality of actuators. The controller is able to simultaneously extend any one or any combination of the forming members to create a plurality of pockets in a determined pattern in the sheet of material to produce a customized blister pack.

The disclosed technology includes blister package assemblies that include a reusable blister pouch. The blister package assembly can have an enclosure housing having a first card and a second card. The second card can be opposed to a separably joinable to the first card. The blister package assembly can have a reusable blister pouch that can enclose an object and have a fastener that transition the reusable blister pouch between an open configuration and a closed configuration. The reusable blister pouch can be secured between the opposing first and second cards when the first and second cards are joined and a portion of the reusable blister pouch can displayed through an opening of the first card and/or the second card.

At least one individually sealed dental composition that includes a layer of a thermoplastic film; a covering film that is a heat sealable or pressure sealable adhesive liner that covers a dental cement composition; a seal around an individual use dosage of the dental cement composition wherein the extrudable dental cement composition is extrudable through a die. The dental cement composition typically has a textured surface thereon and the at least one dry, powdered hydrophilic polymeric substance is engaged with and dispersed on the textured surface of the dental cement composition.

Disclosed are an entrained polymer or an entrained polymer composition, and a method for forming and adhering an entrained polymer structure to a substrate using the entrained polymer or an entrained polymer composition. The method includes providing a substrate configured to receive application of a molten entrained polymer. A particulate entrained polymer in molten form is applied in a predetermined shape, to a surface of the substrate, to form a solidified entrained polymer structure on the substrate. The entrained polymer includes a monolithic material formed of at least abase polymer and a particulate active agent. The surface of the substrate is compatible with the molten entrained polymer so as to thermally bond with it. In this way, the entrained polymer bonds to the substrate and solidifies upon sufficient cooling of the entrained polymer.
