In an embodiment, a polymer includes less than 99.5 percent by weight of units derived from one or more olefin monomers. The polymer also includes greater than 0.5 percent by weight of units derived from one or more blue light absorbing monomers. In another embodiment, a method includes placing a heated parison of a polymer in a mold. The polymer is formed by polymerizing a mixture of one or more olefin monomers and one or more blue light absorbing monomers. The polymer has one or more blue light absorption characteristics. The method includes closing the mold. The method includes injecting gas into the parison to form a container in the mold. The method also includes removing the container from the mold.

A film including a polymer matrix with a first refractive index, a component with a second refractive index embedded in the polymer matrix in a disordered arrangement, wherein the second refractive index is different from the first refractive index, wherein the film scatters 400 to 500 nm wavelengths of light and allows transmission of wavelengths of light from 600 to 800 nm.

Several embodiments include a cooking instrument. The cooking instrument can select a food cooking recipe and identify relative areas in a cooking chamber to place at least two portions of food. The relative areas would match the food cooking recipe. The cooking instrument can display information associated with an instruction to place the at least two portions of food over the relative areas. The cooking instrument can then determine a heating sequence in accordance with the food cooking recipe and control, based on the heating sequence, a heating system to directionally transfer heat under different heating characteristics respectively to the at least two portions of the food at the identified relative areas in the cooking chamber.

A liquid condiment container includes a bottle and a cap. A liquid condiment for the container has a viscosity from 5 to 500 Pa.Math.s, and the container has an initial volume of 100 to 700 cm.sup.3. The body has a flat shape in horizontal transverse section in an erect state with a short axis Q and a long axis R that are orthogonal to a center axis X. The bottle has an inner pressure of 1.0 to 3.0 kPa after 30 seconds of sucking air from the bottle, the air being sucked by 10% of the initial volume from when the bottle is completely filled air. The bottle is flexibly deformed to easily discharge its content even when the content is a high-viscosity liquid condiment, and the original aesthetic appearance of the container is unlikely to be impaired even when the content is reduced.
