The funnel can include a second conical portion having a different cone angle from the cone angle of the first conical portion. The funnel can include a first cylindrical section, e.g., located at the first end of the funnel. The funnel can include a second cylindrical section, e.g., at the second end of the funnel.
In general, in another aspect, the invention features a container, including: a funnel having a first opening at a first end and a second opening at a second end opposite the first end, the funnel defining a funnel volume between the first and second openings and the first opening being larger than the second opening; a first foil seal covering the funnel at the first end, the first foil seal sealing the first opening; and a second foil seal covering the funnel at the second end, the second foil seal sealing the second opening, wherein when a liquid or fine-grained substance is placed within the funnel volume the first and second foil seals seal the liquid or fine-grained substance within the funnel volume.
Embodiments of the container can include one or more of the following features and/or features of other aspects. For example, the first and second foil seals can include a tab extending beyond the respective funnel openings, the tabs being sufficiently large to be gripped between a person's thumb and forefinger. The foil seals can be aluminum foil seals.Among other advantages, funnel-shaped containers can conveniently function to both store a liquid or fine-grained substance and to transfer the liquid or substance to another container in a manner that avoids spillage. Using such containers, a person can avoid having to carry both a funnel and a separate container.

DETAILED DESCRIPTION
Referring to Figs. 1A, a funnel-shaped container 100 is composed of a funnel 110, a first cap 120, and a second cap 130. Funnel 110 is a pipe including a conical section 116 (i.e., a frustum) between a two cylindrical sections 117 and 118. Fig. lA shows container 100 with caps 120 and 130 detached from funnel 110. Fig. IB shows the caps attached. At one end, funnel 110 has a wide opening 112. At the opposite end, the funnel has a narrower opening 114. The diameter of funnel 110 decreases monotonically from along the length of conical section 116. Cylindrical sections 117 and 118 include screw threads on their outer surface for securing the funnel to caps 120 and 130, respectively.
Caps 120 and 130 each include a disc-shaped planar portion (122 and 132, respectively) and a cylindrical portion (124 and 134, respectively). Disc-shaped planar portions 122 and 132 are sized to cover funnel openings 112 and 114, respectively.
Cylindrical portions 122 and 134 include screw threads on their inner surfaces that mate to the screw threads, allowing one to easily secure the caps to and detach them from the funnel. When attached, caps 120 and 130 seal the funnel openings so that a liquid or powder, for example, in the funnel volume doesn't leak out. The caps can include an o- ring seal to facilitate a good seal with the funnel.
Funnel 110 also includes a scale, allowing one to meter then amount of liquid or other substance placed into container 100.
In general, the volume and shape of funnel 110 can vary as desired and typically depends on the intended use for the funnel. The funnel volume can be in a range from 10 ml (e.g., 20 ml, 50 ml, 60 ml, 70 ml, 80 ml, 90 ml, 100 ml, 150 ml, 200 ml, 250 ml, 300 ml, 500 ml) to 1 liter or more. The size of each opening can also vary as desired. In some embodiments, smaller opening 114 has a diameter in a range from 0.5 cm (e.g., 0.75 cm, 1 cm, 1.5 cm, 2 cm, 2.5 cm) to 5 cm. Larger opening 112 can have a diameter in a range from 2 cm (e.g., 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm) to 10 cm or more (e.g., 15 cm, 20 cm). The ratio between the diameter of the large opening to the smaller opening can be 2-to-l or more (e.g., 3-to-l or more, 4-to-l or more, 5-to-l or more).
The length (i.e., distance between the openings) of the funnel can also vary as desired. In some embodiments, the funnel has a length of 5 cm or more (e.g., 7.5 cm or more, 10 cm or more, 12 cm or more, 15 cm or more, 20 cm or more, 25 cm or more, 30 cm or more, 40 cm or more, 50 cm or more). The ratio between the length of the funnel and the diameter of the wide opening can be 1-to-l or more (e.g., 4-to-3 or more, 3-to-2 or more, 2-to-l or more, 3-to-l or more, 4-to-l or more, 5-to-l or more, 6-to-l or more).
The cone angle of conical section 116 can vary as desired. The cone angle refers to the angle the conical section would form if extended to an apex. Generally, the cone angle should be sufficiently low so that the material in the funnel can flow out of the small opening under gravity when the small opening faces downward. The cone angle can be in a range from 10° (e.g., 15°, 20°, 25°, 30°) to 90° (e.g., 75°, 60°, 45°) or more. In some embodiments, conical section 116 includes portions having different cone angles. For example, section 116 can include a portion adjacent wide opening 112 has a first larger cone angle, while a portion adjacent opening 114 has a lower cone angle, e.g., forming a spout.
While the funnels described above have smooth outer walls, other form factors are also possible. For example, in some embodiments, the outer wall of the funnel can include ridges or grooves extending between the two orifices. Referring to Figs. 2A and 2B, for example, a funnel-shaped container 200 includes a funnel 200 that has ridges 212 on its outer surface. Ridges run between the funnel orifices and protrude a height, h, from the surface of funnel 200. Generally, h can vary. In some embodiments, h is in a range from 0.1 mm (e.g., 0.2 mm, 0.3 mm, 0.5 mm, 0.8 mm, 1 mm) to 3 mm.
Ridges or grooves may be beneficial as they can provide separation between the outer wall of the funnel and the inner surface of a container into which the funnel is used to transfer material. The separated surfaces provide channels through which displaced gas from the container can exit. This can facilitate easier funneling of liquid or powder into the container as displaced gas can exit the container through channels other than the funnel.
Alternatively, or in addition to having grooves or ridges on the outer surface of the funnel, when the container includes threaded portions (i.e., for screw on caps), the
threading may include discontinuities or undulations to avoid having the threading form a seal with the opening of a receiving container.
While the foregoing funnel-shaped containers use threading to secure the caps to the funnel, other securing mechanisms are also possible. For example, snap-on caps can be used, such as those found in many commercially-available storage containers, such as containers branded Tupperware or Rubbermaid. Snap on caps can be fixedly attached to the funnel at each end with a hinge element. Generally, any securing mechanism that provides the user with the ability to easily (e.g., using only their hands) and repeatedly remove and secure the caps to the funnel, and that adequately seal the container can be used.
While the caps described above are intended to repeatedly seal and un-seal the funnel openings, in some embodiments the openings can be sealed with a single use seal, such as an aluminum foil seal secured to the funnel at the openings by a releasable adhesive. The foil seal can include a tab to facilitate removal. The foil seal can be similar to those use in commercially-available food containers, such as yoghurt containers. In some embodiments, a cap, e.g., a snap-on cap, can be provided at one or both openings in addition to a removable seal.
In general, the funnel-shaped containers can be formed from a variety of materials, such as plastics, glasses, or a metal or alloy (e.g., aluminum or stainless steel). In some embodiments, the containers are formed from a plastic considered safe for storage of food or other nutritional products. Useable plastics may include, for example, Polyvinyl chloride (PVC), Polystyrene, Polycarbonate, Polyethylene terephthalate ethylene, High-density polyethylene, Low-density polyethylene, and Polypropylene (PP). Useful glasses include, for example, commercially-available glasses used for kitchenware or laboratory purposes, e.g., pyrex. In some embodiments, the funnel can be formed from a ceramic material.
In some embodiments, funnel-shaped containers are formed from cardboard, e.g., with a plastic liner to provide adequate sealing for liquid storage.
In general, the caps and funnel can be formed from the same material, or from different materials. For example, the funnel can be formed from a glass, while the caps are formed from a plastic.
The funnel-shaped containers can be formed using a variety of known methods, such as injection molding (e.g., for plastic containers) or conventional glassware-shaping methods (e.g., for glass containers).
In general, the containers disclosed herein can be used for a variety of purposes. For example, they can be used by consumers for the storing, transport, and transfer of pre-measured amounts of a nutritional substance. For example, funnel-shaped containers can be used to store, transport, and/or transfer pre-measured amounts of baby-formula or a nutritional supplement (e.g., a protein powder or other dietary supplement). The volume of such containers can correspond to one or more servings (e.g., one, two, three, or four or more scoops) of the baby formula or nutritional supplement.
Funnel-shaped containers can be used by airline passengers to store, transport, and/or transfer airline-security-permitted volumes (e.g., 3.4 oz, 100 ml or less) of liquids or powders in their carry-on luggage. For example, travellers can use funnel-shaped containers to store airline-security-permitted volumes of toiletries or nutritional substances.
Funnel-shaped containers can also be used in a medical or laboratory
environment. For example, containers can be used to transport, store and/or transfer medical specimens. In a laboratory, funnel-shaped containers can be used to transport, store, and/or transfer, e.g., specimens or reagents.
A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. For example, in some embodiments one or both caps can include a valve (e.g., a stopper that plugs a small opening in the planar portion of the cap) that allows one to purge the funnel volume while emptying the container through the opposite opening. Such a valve can prevent formation of vacuum in the container that hinders removal of the liquid or substance from the container. Accordingly, other embodiments are within the scope of the following claims.
