The present disclosure relates to the field of packaging, and specifically to packages comprising containers for housing powders. More particularly, the disclosure relates to packaging comprising a container having a main body to hold the powder and two closures, and a dispensing utensil for measuring and dispensing the powder.
Currently, products in granular or powdered form, including but not limited to infant formula powders, instant coffee, instant tea, powdered cocoa, powdered sports drinks, etc., are packaged in containers. Dispensing utensils, such as scoops, may be provided within such containers for measured dispensing of the powdered products. However, if the scoop is merely dropped into the container when the container is filled with the powder, the scoop will tend to settle to the bottom of the container during shipment and storage. This settling makes it difficult for the consumer to locate and remove the scoop from the container without spilling the powder contents, getting the powder on their hands, or potentially contaminating the powder. This can both waste the powder and create potential hygienic problems, which can be ongoing if the scoop is dropped back into the container after each use.
Some manufacturers have designed containers with fasteners, retaining clips, or docking stations that hold the scoop in a more convenient location, such as on the container lid or a container side wall. However, the scoop may still be coated with powder when the container is moved, tipped, or jostled, resulting in more spillage, soiling of the hands, and potential contamination of the powder remaining in the container.
The package of the present disclosure provides a container with an innovative closure system that provides a location for storing a scoop, cleanly separates the scoop from the powder housed within the container, and controls the spillage of the powder each time the container is opened. In one embodiment, the container comprises a main body, a first hinged closure, and a second hinged closure. The main body comprises sidewalls and a bottom wall forming a compartment, and an upper lip on the sidewalls that defines an opening to the compartment. The first hinged closure is configured to fully cover the opening of the compartment, and forms a resealable seal with the upper lip of the main body. The first hinged closure further comprises a top face and a bottom face, with a pocket on the top face for receiving the bowl of a scoop. The second hinged closure is configured to cover the first hinged closure.

The main body 20 comprises a plurality of side walls 22 and a bottom wall 24, which define a compartment 21, and an upper lip 26 on the sidewalls 22 that defines an opening 23 to the compartment 21. In some embodiments, a ledge 26b (shown in
The main body 20 is sized such that the compartment 21 is of suitable volume to hold an appropriate amount of powder. Suitable volumes for the compartment 21 may include, but not be limited to, about 250 mL, about 500 mL, about 1000 mL, about 1500 mL, about 2000 mL, and about 2500 mL. The side walls 22 are sized such that the compartment 21 is of suitable height and cross-sectional area to be easy to manufacture, fill, carry, and use. Suitable heights for the compartment 21 may include, but not be limited to, from about 5 cm to about 30 cm in height, including from about 7.5 cm to about 25 cm, about 10 cm to about 20 cm, and about 12.5 cm to about 15 cm in height. Suitable cross-sectional areas for the compartment 21 may include, but not be limited to, from about 25 cm2 to about 1000 cm2 in area, including about 50 cm2 to about 900 cm2, about 100 cm2 to about 800 cm2, about 150 cm2 to about 600 cm2, about 200 cm2 to about 500 cm2, and about 250 cm2 to about 400 cm2 in area.
The side walls 22 and bottom wall 24 are of suitable thicknesses such that the main body 20 is free standing, self-supporting, and capable of containing the powder without rupture during normal manufacturing processes, transport, and use by the consumer. Suitable thicknesses for the side walls 22 and bottom wall 24 may include, but not be limited to, from about 0.2 mm to about 3 mm in thickness, including from about 0.3 mm to about 2 mm, about 0.4 mm to about 1.5 mm, and including from about 0.5 mm to about 1 mm in thickness. It should be understood that the side walls 22 and the bottom wall 24 do not necessarily have the same thicknesses, i.e., the bottom wall 24 may be a different thickness from the side walls 22, and individual side walls 22 may have different thicknesses from one another.
In some embodiments, the main body 20 may further comprise a removeable seal (not shown), such as a foil seal or a polymeric film seal, as is known in the art. The removeable seal may be attached to the upper lip 26 to contain and protect the powder enclosed in the compartment 21 between the time the compartment 21 is filled and the consumer accesses the compartment 21 for the first time. The consumer may remove and discard this seal to access the contents of the compartment 21.
The main body 20 may be manufactured from any suitable material, such as but not limited to, a rigid or semi-rigid material polymeric material. In some embodiments, the main body 20 is manufactured from a polymeric material such as high-density polyethylene (HDPE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), or similar polymeric materials. In some embodiments, the main body 20 is manufactured from an opaque material. In some embodiments, the main body 20 is manufactured from a translucent or transparent material. In some embodiments, the main body 20 is manufactured using an injection molding process, as is known in the art.
