Blister pack for a container

Abstract

The present invention relates to a blister pack sealed to the neck of a container and adapted to fit under the container lid forming a seal, said blister pack containing a liquid soluble material such as dissolvable aspirin. When force is applied to the blister pack, the base, which is comprised of a rupturable material, breaks and allows the liquid soluble material to be mixed with the liquid in the container. The blister pack remains as a seal for the container until it is desired that the user remove the blister pack for access to the container. The user can then re-seal the container using the container lid.

Description

FIELD OF THE INVENTION[0001]This invention relates to a blister pack, particularly for use with food and beverage containers.BACKGROUND TO THE INVENTION[0002]Sealing methods for food and beverage containers are well known and varied, the most common being a cap or lid. Drinks which include another component or second component, such as a tablet or powder which is added to the liquid are growing in popularity. Usually this includes a blister pack contained in the lid which is adapted to store material separately from the liquid in the container.[0003]It is preferable for the second component to be added immediately prior to consumption, especially when ingredients to be added are UV sensitive or do not have a long shelf life when mixed. Adding ingredients at the point of consumption also simplifies the production and filling of the beverages.[0004]It is therefore known for a container to include a cap and powder or tablet holder, or blister pack, so that when pressure is exerted on t...

AI Technical Summary

Benefits of technology

The invention is a blister pack that can be used with a container to add a liquid or powdered element to the contents of the container. The blister pack has a rupturable base and a formable cover that can be sealed to the container's opening. The base ruptures when a minimum amount of force is applied on the cover, causing the element to fall into the container body. The blister pack can be easily detached from the container and has tabs that break the seal. The container also includes a lid that can seal the opening when the blister pack is removed. The base is of lower burst strength than the cover and is made of aluminum or thermoformable or coldformable plastic. The container can also have a removable attachable lid that seals the opening when the blister pack is removed. The invention provides a convenient and easy way to add elements to liquid or powdered contents of containers.

Problems solved by technology

However, there are various disadvantages in the known prior art, for example, wherein the blister pack is completely broken by the initial force to release the material, and therefore does not remain sealed whilst the two components are being mixed.

Furthermore, the container cannot be resealed once the tablet holder is broken and therefore the container cannot be reused.

In many designs, the remains of the tablet holder, once broken, cannot be easily removed from the container, which may affect the drinking of the beverage and its reusability.
