Description

 Container containing absorbent cloth  

The present invention relates to containers for containing particulate or powder products, such as for infant formula. More particularly, the invention relates to an absorbent container comprising a configured oxygen and/or moisture vapor absorbing material. The invention also relates to a can lid comprising an absorbent material and a method of making an absorbent container.

There are many products in particulate form that are currently stored in containers and sold in containers. These products include infant formula, flour, coffee, sugar, fortifiers and nutritional supplements such as protein or dietary supplements. It is important that manufacturers and consumers prefer products that have a long shelf life or that the product remains available, suitable for consumption or for sale. Moreover, product quality deteriorates beyond its shelf life; products with long shelf life maintain a higher quality than products with short shelf life. Many factors affect the shelf life of stored products in addition to basic product stability, including relative humidity, relative oxygen content, temperature, and light. Therefore, containers for storage products should minimize the impact of these factors.

In addition, the container should be user-friendly for the end consumer. A user-friendly container is a container that facilitates storage, use, and retrieval, measurement, and dispensing of the products contained therein by the end consumer. User-friendly containers should also minimize the risk of contamination or immersion of the container components and the risk of providing end-user consumption. For example, a desiccant that is directly mixed with the product can provide too much risk of product contamination or risk of actual object consumption.

Moreover, the container should also be capable of being manufactured using new container designs, manufacturing methods and materials and compatible with new container designs, manufacturing methods and materials. Containers made of plastic and/or metal are often used to store and sell a variety of particulate products, particularly in the industrial, food and pharmaceutical industries. The new container manufacturing and product packaging can be placed on the container, for example, before or after filling the container with the product, in a separately manufactured can end or can lid. Two-piece metal can be manufactured by, for example, stamping cans from metal coils, screeding cans to longer lengths and forming integrated bottom can lids, trimming cans to lengths, cleaning cans, printing on cans, painting, drying The can, applying a protective coating to the inside of the can, the second drying can, filling the container with the product, and placing the can lid on the can.

One product manufacturer extends the shelf life of the product by removing most of the air from the container after the product is added to create a vacuum, purging the container with inert nitrogen and sealing the container. However, residual oxygen is often left in the product and reduces product shelf life. In the case of nutritional compositions, product lipids, vitamins and probiotics are particularly susceptible to oxidation, and thus oxidizing product lipids, vitamins and probiotics with residual oxygen results in termination of product shelf life. Likewise, such probiotic-favorable bacteria, often included in nutritional compositions, also tend to be moisture sensitive. Therefore, there is still a need to better isolate the oxygen and/or moisture in the container after the product is added.

Long and stable shelf life is especially important in environments that are not refrigerated and in addition to where the product may be exposed to a variety of environments, especially those associated with tropical climates. In addition, mixing with the product and the oxygen contained in the product is challenging for isolation techniques such as vacuum. Ideally, the container should have a long shelf life (i.e., at least about 30 ° C and up to and above 40 ° C) at high temperatures during dispensing and storage and isolate oxygen and/or moisture from the container chamber and product.

Therefore, there is still a need for a container that provides a long shelf life that is easily incorporated into new container manufacturing and product packaging and that is user-friendly. In addition, there is still a need for packaging products in containers to increase the shelf life of the product.

In one embodiment, the container includes a can lid defining a sidewall of the interior chamber and an attachment sidewall. The can lid may include a concave concave body integrally formed in the can lid and open to the chamber. At least one barrier layer may be disposed between the concave body and the chamber or separate the concave body from the chamber. The can lid may include a central body on which the concave body is disposed. The oxygen absorbing material can be disposed within the concave body. The oxygen absorbing material can be a granule.

In one embodiment, the at least one barrier layer includes a gas barrier layer and a second barrier layer. The gas barrier layer may face the interior chamber and the bottom layer may face the concave body. The gas barrier layer may be composed or constructed of a metallized film having a polymer layer and a metal layer disposed on the polymer layer.

The inclusion of probiotics is currently not feasible due to the shelf life of the probiotics in the current containers, but the invention may specifically allow, for example, probiotics to be stored in the nutritional composition product. The present invention also extends the shelf life of probiotics currently included in nutritional composition products.

Additional benefits including oxygen absorbing material 18 and/or moisture absorbing material 19 include: extending the shelf life of product 11; providing a more consistent product 11 quality; faster product 11 packaging; preventing aerobic pathogens and spoilage organisms in Growth in chamber 13; reduction and prevention of oxidation of lipids, vitamins and products 11; and preservation of the freshness of product 11. Longer shelf life is particularly important in tropical countries and locations where the product is placed on shelves that are exposed to high ambient temperatures and/or high relative humidity.

The concave body 16 may be covered by at least one barrier layer 20 such that the oxygen absorbing material 18 and/or the moisture absorbing material 19 is disposed between the concave body 16 and the barrier layer 20, and the barrier layer 20 is disposed in the concave body 16 and the chamber Between 13 The barrier layer 20 can comprise multiple layers. In one embodiment, the barrier layer 20 includes a gas barrier layer 22 (ie, an oxygen and/or moisture barrier) and a second barrier layer 24. The gas barrier layer 22 can be an oxygen and/or moisture barrier, and the second barrier layer 24 can separate the absorbent material 18 from the product 11 while providing a surface on which the gas barrier layer 22 is disposed. The second barrier layer 24 can be configured to attach to the can lid 14, for example by bonding the second barrier layer 24 to the can lid 14, such as with a heat sealant. The gas barrier layer 22 may face the chamber 13 and the second barrier layer 24 may face the concave body 16. The gas barrier layer 22 may be constructed of a polymeric film that is a low barrier to oxygen and/or moisture vapor, coated with aluminum or other thin layer of oxygen and/or wet vapor high barrier.
