The present specification relates to funnels, and in particular to funnels for transferring flowable materials.
Transferring a flowable material into a receptacle with a relatively narrow inlet may be challenging because some of the material may fail to enter the inlet and cause spillage and waste.
An aspect of the present specification provides a funnel comprising: a body forming a conduit for a flowable material, the body having an inlet to receive the flowable material and an outlet to output the flowable material, the flowable material to move from the inlet to the outlet along an axis of material movement, the body having a stem portion proximate the outlet, the stem portion for being at least partially received into a corresponding inlet of a receptacle for transferring the flowable material into the receptacle; and one or more fins positioned in the stem portion, the one or more fins extending from an outer surface of the body laterally to the axis of material movement, the one or more fins to abut against an inner surface of the corresponding inlet of the receptacle when the stem portion is at least partially received in the corresponding inlet of the receptacle.
At least a portion of the body may have a frustoconical shape.
The body may comprise an inlet portion proximate the inlet, the inlet portion connected to the stem portion; and the inlet portion may have a first frustoconical shape having a first taper and the stem portion may have a second frustoconical shape having a second taper different from the first taper.
At least one of the fins may have a circular perimeter.
The funnel may comprise a first fin, a second fin, and a third fin, spaced from one another along the axis of material movement, the first fin being closest to the inlet, the third fin being closest to the outlet, and the second fin being disposed between the first fin and the third fin.
The first fin, the second fin, and the third fin may have a circular perimeter and a first diameter, a second diameter, and a third diameter respectively; and the first diameter may be larger than the second diameter, and the second diameter may be larger than the third diameter.
The second fin may be positioned about midway between the first fin and the third fin along the axis of material movement.
The one or more fins may be to resiliently deform against the inner surface of the corresponding inlet of the receptacle when the stem portion is at least partially received in the corresponding inlet of the receptacle.
The one or more fins may comprise silicone.
The one or more fins may be integrally formed with the stem portion of the body.
At least one of the fins may comprise a through hole.
In the drawings, identical reference numbers identify similar elements or acts. The sizes and relative positions of elements in the drawings are not necessarily drawn to scale. For example, the shapes of various elements and angles are not necessarily drawn to scale, and some of these elements may be arbitrarily enlarged and positioned to improve drawing legibility. Further, the particular shapes of the elements as drawn are not necessarily intended to convey any information regarding the actual shape of the particular elements, and have been solely selected for ease of recognition in the drawings.
In the following description, certain specific details are set forth in order to provide a thorough understanding of various disclosed implementations. However, one skilled in the relevant art will recognize that implementations may be practiced without one or more of these specific details, or with other methods, components, materials, and the like.
Moreover, in the following description, elements may be described as “configured to” perform one or more functions or “configured for” such functions. In general, an element that is configured to perform or configured for performing a function is enabled to perform the function, or is suitable for performing the function, or is adapted to perform the function, or is operable to perform the function, or is otherwise capable of performing the function.
It is understood that for the purpose of this specification, language of “at least one of X, Y, and Z” and “one or more of X, Y and Z” can be construed as X only, Y only, Z only, or any combination of two or more items X, Y, and Z (e.g., XYZ, XY, YZ, ZZ, and the like). Similar logic can be applied for two or more items in any occurrence of “at least one . . . ” and “one or more . . . ” language.
Unless the context requires otherwise, throughout the specification and claims which follow, the word “comprise” and variations thereof, such as, “comprises” and “comprising” are to be construed in an open, inclusive sense, that is as “including, but not limited to.”
As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise. It should also be noted that the term “or” is generally employed in its broadest sense, that is as meaning “and/or” unless the content clearly dictates otherwise.
The headings and Abstract of the Disclosure provided herein are for convenience only and do not interpret the scope or meaning of the implementations.
In order to reduce the likelihood of spillage and waste when transferring a flowable material into a receptacle a funnel may be used to facilitate the transfer of the material into the receptacle. Some funnels may fit loosely into the inlet of the receptacle. As such, when the flowable material is deposited into the funnel, the funnel may move or tip causing some of the material to be spilled.
In addition, some funnels may have an inlet portion connected to a stem portion terminating in an outlet of the funnel. When the flowable material is deposited into the inlet portion, the inlet portion of the funnel may become top-heavy, further exacerbating the tipping or moving challenges that may be associated with funnels that fit loosely into a corresponding receptacle. Moreover, if the transfer of the flowable material is to happen on a sloped terrain or if the inlet of the receptacle is at an angle to the horizontal, a funnel may become more susceptible to moving or tipping when the flowable material is transferred into the inlet portion of the funnel.
In some examples, the flowable material may comprise a liquid, a liquid-based suspension or mixture, a slurry, and the like. Moreover, in some examples, the flowable material may comprise the granular solid, a powder, and the like. In some examples, the flowable material may comprise a material that can flow through a conduit. Moreover, in some examples, the flowable material may comprise a material that can flow through a conduit under its own weight. When deposited in funnel 100, the flowable material may move from inlet 110 to outlet 115 along an axis 120 of material movement.
Moreover, body 105 may have a stem portion 125 proximate outlet 115 and an inlet portion 130 proximate inlet 110. As shown in
Funnel 100 also comprises three fins 135, 140, and 145 positioned in stem portion 125 of funnel 100. These fins extend from an outer surface 150 of body 105 laterally to axis 120 of material movement. In operation, one or more of fins 135, 140, and 145 abut against an inner surface of the inlet of the receptacle when stem portion 125 is at least partially received in the inlet of the receptacle. By abutting against the inlet of the receptacle, the fins reduce the movement of funnel 100 relative to the inlet of the receptacle. In other words, by abutting against the inlet of the receptacle, the fins create a relatively tighter fit between funnel 100 and the inlet of the receptacle. By creating a tighter fit between funnel 100 and the inlet of the receptacle, and by reducing movement of funnel 100 relative to the receptacle, the fins may reduce the likelihood of funnel 100 moving or tipping in operation and causing spillage of the flowable material.
As shown in
In addition, as shown in
Furthermore, while
Moreover, in
In the example funnel 100 shown in
In some examples, the fins may be formed separately from body 105, and then secured to body 105. Moreover, in some examples, one or more of the fins may be integrally formed with a portion of the body 105, such as stem portion 125. In funnel 100, the fins extend radially relative to axis 120 of material movement, and form about a right angle with axis 120. It is contemplated that in some examples, the angle between the fins and axis 120 may be different than a right angle. Moreover, in some examples, the angle between the fins and axis 120 may be an angle greater than 0° and smaller than 180°. This angle may be selected to allow the fins to interact with the inner surface of the inlet of the receptable, to reduce the likelihood of movement of the funnel relative to the receptacle in operation. It is also contemplated that in some examples, all of the fins need not form the same angle with axis 120, and that some of the fins may form different angles with axis 120.
Furthermore, in some examples, in addition to abutting the inner surface of the inlet of the receptacle, the fins may be resiliently deformed against the inner surface of the inlet of the receptacle when stem portion 125 is at least partially received in the inlet of the receptacle. The resilient force of such resiliently deformed fins against the inlet of the receptacle may further reduce the likelihood of movement of funnel 100 relative to the receptacle. In addition, the use of resiliently deformable fins may allow funnel 100 to be used with receptacles having inlets of different sizes. Such resiliently deformable fins would deform less when stem portion 125 is received inside a receptacle with a relatively wider inlet, and would perform relatively more when stem portion 125 is received inside a receptacle with a relatively narrower inlet.
In some examples, such resiliently deformable fins may comprise a resiliently deformable material such as an elastomer, composite material, and the like. Moreover, in some examples, one or more of the fins may comprise silicone, and the like. It is contemplated that in some examples, the fins may be more easily resiliently deformable than the stem or body of the funnel. Such fins may also be described as being more flexible than the stem or body of the funnel. For example, the body or stem of the funnel may comprise a relatively less flexible material such as a plastic, metal, or the like, while the fins of the funnel may comprise a relatively more flexible material such as silicone, and the like. In some examples, depending on the choice of the material of the body and the fins, the fins may either be formed separately from the body and then secured to the body, or formed integrally with a portion of the body.
As shown in
Having fins of different diameters may allow at least some of the fins to interact with a range of sizes of inlets of receptacles. For a relatively narrower inlet, relatively more of the fins may abut or interact with the inlet. Such a relatively greater extent of interaction may allow for a tighter or more secure fit between the funnel and the inlet of the receptacle. For a relatively wider inlet, relatively fewer of the larger diameter fins may interact with that relatively wider inlet. If all the fins were to be made as large as the largest fin, the fins might present too much resistance when the fins are to be received in a relatively narrower inlet of a receptacle. By having a range of fin sizes or diameters, funnel 100 may be operable with a greater range of sizes of inlets of receptacles.

In addition, in
In addition, it is contemplated that in some examples the relative sizes or diameters of the fins may be different than those shown in
Furthermore, while
Turning now to
As discussed above, in operation holes 450, 455, and 460 may allow for enhanced venting when funnel 400 is used to transfer a flowable material into a receptacle. In addition, the holes may reduce the amount of material used to make the fins, and allow for corresponding reductions in funnel weight, cost, and environmental impact. While
In some examples the fins may have a non-continuous shape, such as a web shape, a truss shape, and the like. In some examples, the through holes defined by such fins may have shapes other than a circular shape. Moreover, it is contemplated that in some examples, instead of or in addition to the through holes, one or more of the fins may have an uncommonly-shaped perimeter. Such a perimeter with an uncommon shape may be shaped to be less likely to form a substantially air-tight seal with the inlet of the receptacle, and therefore be less likely to pose a hindrance to venting in operation. An example of such a perimeter may include a perimeter with a semi- or part-circular cut-out removed the perimeter. Cut-outs of other shapes are also contemplated. Other examples of such uncommonly-shaped perimeters may include a star-shaped perimeter, an undulating curved perimeter, and the like.
