Plastic jars have ridges for a variety of reasons. The most common reason is that the ridges add structural integrity to the jar, preventing it from buckling under pressure. Additionally, the ridges allow for easy stacking and provide grip, preventing the jar from sliding off a flat surface. The ridges also indicate where two halves of the finish molds were joined during manufacturing.

What You'll Learn
The base of the plastic jar
The base of a plastic jar is its bottom part, where it stands upright and stable. This is where you will find recycling codes, material marks, cavity and punt marks, or other decorations. The base may also have a small projection or recess that serves as a registration device for labelling and decorating equipment. These registration devices ensure that labels and decorations are applied consistently and accurately to the jar.
The base of a jar is distinct from the heel, which is the lower part of the jar where the sidewall turns from vertical to horizontal. The heel may also have a small recessed spot that serves as a registration device for labelling and decorating.
The base of a plastic jar is an important part of its anatomy. The shape and design of the base can vary depending on the specific use of the jar. For example, a jar intended for long-term storage may have a different base shape than one intended for dispensing through pumps.
Plastic jars offer several advantages over glass jars in terms of functionality, design, and sustainability. They are more lightweight and shatter-resistant, making them safer for children and use in fast-paced environments like restaurants and bars. Plastic jars also require less torque to open and close, keeping the lid tight and maintaining the freshness of the contents.

Recycling codes on the base
Plastic containers, including jars, have a number of disadvantages compared to glass containers. Plastic is not biodegradable, and it loses integrity each time it is recycled. It can also leach chemicals into its contents, especially when hot substances are added or when food is microwaved in plastic containers. Plastic can also absorb and house harmful microbes, making long-term use potentially unsafe.
However, plastic containers have some advantages over glass. Plastic bottles and jars are easier to open and close than glass containers, making them more user-friendly, especially for children or in fast-paced environments like restaurants. Plastic is also less energy-intensive to produce than glass, and it has a lower carbon footprint.
Recycling codes are found on the base of plastic containers, along with material marks, cavity and punt marks, and other decorations. The base of a container is the bottom part that allows the container to stand upright in a stable manner. The base may also have a small projection or recess that serves as a registration device for labelling and decorating equipment.
Recycling codes are used to identify the type of plastic a container is made of, which is important for proper recycling. Different types of plastic require different recycling processes, and some plastics may not be recyclable at all. Checking the recycling code can help individuals and recycling facilities sort and process plastic waste appropriately.
In addition to recycling codes, the base of a plastic container may also have a cavity mark, which is a small indentation, or a punt mark, which is a small dimple or bump. These marks are typically found on the bottom of larger containers and can provide information about the manufacturer or the mould used to create the container.

The heel of the jar
The heel of a jar or bottle is the lowest portion of the container, where the sidewall (or body) transitions from vertical to horizontal, curving into the base. It is smoothly integrated to support and transition to the flat base, providing stability to the jar or bottle. The heel is also known as the "insweep".
The heel is an important part of the jar or bottle's anatomy, as it can include specific design features that enhance stability. A well-designed heel will ensure the bottle rests evenly and doesn't tip over easily. For example, the heel may have a small recessed spot that serves as a registration device for labelling and decorating equipment. This device can also take the form of a small projection along the heel of the container.

The pushup
The mouth, or opening of the container, can vary in size depending on its intended use. Plastic jars, for instance, typically have a wide mouth with a large opening, making it easier to access the contents. In contrast, bottles usually have a narrower opening, which is better suited for pouring liquids. The neck of the container is the portion just below the mouth, and the shoulder is the sloped area above the main body of the container. The slope of the shoulder can vary depending on the intended use of the container, with a more sloped shoulder being better suited for pouring liquids.
Overall, the pushup plays a vital role in ensuring the stability and functionality of plastic jars and bottles. It is just one of the many carefully designed features that make up the anatomy of a container, each serving a specific purpose to enhance the user experience and protect the contents.

The registration device
Plastic jars have a registration device, which is a small projection or recess on the base or heel of the jar. This device serves as a guide for labelling and decorating equipment during the manufacturing process. It ensures that labels and decorations are applied consistently and accurately to the jars.
The placement of the registration device can vary, depending on the specific design and requirements of the jar. In some cases, it may be located on the base of the jar, where it serves as a stable platform for the container. This small projection on the base ensures that the jar stands upright securely.
Alternatively, the registration device may be found on the heel of the jar, which is the lower part where the sidewall turns from vertical to horizontal. Here, it takes the form of a small recessed spot, providing a consistent reference point for labelling and decoration.

Frequently asked questions
Plastic jars have ridges because they strengthen the container, allowing less plastic to be used. Without them, the container would need to be thicker. Ridges also make it easier to stack jars on top of one another.
The vertical ridge on the neck of a plastic jar is called the mold seam. It indicates where the two halves of the finish molds were joined during manufacturing.
The horizontal ridge on the neck of a plastic jar is called the neck ring or transfer bead. It is used during manufacturing to transfer the jar from one part of the production process to the next.
