Containers for holding materials

Abstract

The invention provides for a container that may include a liquid-holding vessel and a skeleton shell supporting the liquid holding vessel. The liquid-holding vessel may comprise a flexible polymer or plastic material for preventing contact between a liquid stored in or dispensed from the container and the skeleton. The liquid-holding vessel and the closure may be formed from a minimal amount of polymer or plastic. The invention also provides for a connection of a liquid-holding vessel with a fitment to the skeleton shell using ultrasonic means. Further, a skeleton shell with mating features allowing the skeleton shell to be formed with smooth edges is provided.

AI Technical Summary

Benefits of technology

The invention provides containers for holding materials, such as solids and liquids, that are made from polymeric materials and supported by a skeleton shell. The containers can be filled with material through a fitment and sealed or resealed. The fitment can be secured to the skeleton shell using heat stakes or ultrasonic energy. The skeleton shell can have scalloped features or a smooth outer surface. The technical effects of the invention include secure and reliable containers for holding materials that can withstand pressure and impact, as well as being easy to fill and seal.

Problems solved by technology

Packaging used for containing liquids can generate large amounts of waste.

However, the energy required to make the bottles is high.

Also, the weight of the resulting packaging is high, increasing the amount of energy required to transport the products.

This is a problem since, unlike some other forms of waste, glass is not biodegradable.

Again, if the container is disposed of in a landfill site or the like, the bottle is not biodegradable.

Also, bottles take up a volume larger than that of the material itself due to their hollow, rigid, structure, and therefore take up an excessive amount of space in a landfill site.

A problem with such packages is that they are difficult to recycle, and the waterproof coating prevents them fully decomposing.

The problem is exacerbated when a plastic dispensing nozzle or cap is formed as part of the package for dispensing the contents.

However, these bags have little structural stability, and therefore are difficult to transport and to stack on shelves.

They are often not re-sealable, making them hard to hold and carry.

This separation of packaging components is difficult and prevents such packages from being disposed of or recycled efficiently.

Furthermore, in some cases bottles or other liquid containers contain additional, separable components that do not make it into a recycling bin.

For example, loose caps, straws, and plastic tamperproof or tamper-evident devices can contribute to overall litter in the environment.

Even if bottles make it into a recycling bin or garbage can, their caps or other types of closures often end up as general litter.
