Deciding what packaging closures you should use depends on the contents being packaged, along with how the consumer will be using the product. Be sure to consider any regulations that could apply to your product, and do not forget to optimize your packaging for the customer’s experience and the shelf appeal of your products.
Dispensing Closures
These are used to control the amount of product that gets dispensed when used. They are commonly used for food, household and health and beauty products. There are dispensing closures better suited for dry products like spices and fertilizers and those best suited for liquids of varying viscosities. Sprayers and pumps are also types of dispensing closures, though they can sometimes be in their own closures category as well.
Crown Cap
The definition of crown cap in the dictionary is an airtight metal seal crimped on the top of most bottled beers, ciders, mineral waters, etc.
CT - Continuous Thread Closures
These are the most basic and commonly used packaging closure. They pair with a container that has a continuous spiral protruding on the outside of the finish or neck, as the closure itself has a thread on the inside of it. These are typically used across several industries including food, household items, pet products, and health & beauty.
CR or CRCs - Child Resistant Closures
These are typically used for products that are required by the Consumer Product Safety Commission to be packaged in child-resistant packaging. That means the packaging must be significantly difficult for children under five years old to open within a reasonable amount of time, while not being overly difficult for a typical adult to use properly. These are typically used for pharmaceuticals and chemical products.
TE - Tamper Evident Closures
These are used when the closure has to provide assurance that the original product is intact. These are very common in the food, beverage, and health and beauty industries. These also provide anti-counterfeiting protection for over-the-counter (OTC) pharmaceuticals and nutraceuticals.

Spray Bottle Cap
