A method of injection molding a test tube-shaped preform for biaxial stretch blow molding includes supplying a major material resin from outer and inner flow paths to a combined flow path for a predetermined time and rate. For a period of time within a range of the predetermined time period during which the major material resin is supplied, the intermediate layer resin is simultaneously supplied from the middle flow path to the combined flow path at a second predetermined supplying rate. A columnar laminated molten resin is injected into a cavity of a metal mold connected to a tip of the nozzle through a gate to fill the cavity, the columnar laminated molten resin being composed of the major material resin and the intermediate layer resin formed in the major material resin in a laminated manner that are combined into a columnar shape at the combined flow path.

Embodiments of the present disclosure provide for a multisensory examination jar for botanical specimens. Embodiments of the disclosed jar may have a body portion with an integrated LED array for illuminating the contents of the jar. The jar may have a removable lid with an integrated magnifying lens, and an opening or port to enable a user to smell the contents of the jar. The opening may have a removable plug to establish a substantially air tight seal on the lid of the jar, to trap odors within the jar. The removable plug can be selectively removed to enable the user to smell the contents of the jar. The jar may have an electronics module and power source operable for wireless charging. The jar may also be configured to interface with a charging dock or base for wireless charging of integrated batteries.

A pressure-based packaging system has an upper frame and a lower frame bounded by a walled containment in which they are placed to hold articles therebetween, the upper frame having spaces for receiving the tops of articles and the lower frame having spaces for receiving bottoms of articles, where either one or both of the upper and lower frames is made from folding a single sheet of material into a box-like form.

A rigid container that may be used to store items. The container includes a first bowl and a second bowl. The first and second bowls both include center portions and at least one sidewall. The sidewalls are disposed about the peripheries of their respective center portions and oriented perpendicular to it. The sidewall(s) of the first bowl define an exterior profile and the sidewall(s) of the second bowl define an interior profile. The exterior profile and the interior profile are identical in shape but the interior profile is slightly larger so that the second bowl can be received over the first bowl.

Disclosed herein are child-resistant containers having an integrated window. The containers have a container base and a container cap. The container cap contains the integrated window so that a user can view the contents stored within the container. The window can be any transparent, semi-transparent or translucent material. The material can control one or more environmental conditions, such as temperature, humidity, oxygen, ultra-violet light and others.
