A bottle is a narrow-necked container that stores and transports liquids. It is typically made of an impermeable material. It can be sealed using an internal stopper, an external bottle cap, or a closure. A bottle can be manufactured in a variety of ways, including injection molding and blowing.
Plastic bottles can be recycled to help reduce the pollution caused by single-use plastics. However, many bottles are still littered in landfills. This plastic waste can take hundreds of years to break down into microplastics. It also can contribute to oceanic gyres, which are large systems of rotating currents in the Pacific Ocean that trap floating debris.
The bottle industry uses two types of plastic: polycarbonate and HDPE. Both are plastics that can be recycled, but HDPE is generally more expensive than other types of bottle-making polymers.
Bottles are manufactured in several steps, beginning with plastic pellets that are heated in a mold to melt them and then injected into the cavity of a Reheat and Blow Machine (RBM). The melted plastic is then injected into multiple-cavity molds, which assume the shape of long tubes called parisons. PET parisons are easily shipped to bottling facilities because they are much more compact than full-formed bottles.
Injection-molded bottles are uncommon, but may be used when tight tolerances are required. This method of manufacture is often used when a single-use application requires a very tight neck. The mouth of the bottle can be sealed with an internal stopper, an external bottle cap, a closure, or induction sealing.
Blow-molded bottles are the most common type of bottle, and they are usually made from high-density polyethylene (HDPE). They can be shaped with both extrusion and injection techniques, and are made in a wide range of sizes and colors.
There are a number of different finishes that can be applied to the finished product. Some finishes are applied to the entire exterior of the bottle, while others may be applied on the inside. The most common finish on the interior of a bottle is an infusion coat, which is a thin layer of colored resin applied to the inside surface.
A good bottle episode should be distinctive and unique. It should force your characters into a situation that they aren’t used to, exposing something they might not have otherwise been aware of. This can allow the writer to explore themes or other elements that might be hard for them to achieve in other episodes.
The bottle episode is a great way to break out of the usual plot structure and delve deeper into character development. If the episode is well-written, it can be a fun break from the norm for fans of your show.
One of the most popular shows of all time, Breaking Bad is a great example of how a bottle episode can be done right. In this episode, Walt and Jesse must kill a fly that infiltrated their meth lab and is contaminating their batches.
