Definitions

  • This invention relates to a holder for paper cone-type coffee filters used with drip-type coffee makers.
  • the prior art provides numerous embodiments of holders/dispensers for paper coffee filters of the non-cone variety, e.g.. pleated basket type. In those constructions the paper filters nest within one another, like the skin of an onion. Each time one is used or dispensed the next one presents itself.
  • FIG. 1 illustrates the configuration of a typical construction of a cone-type (e.g., Melitta type) filter described above.
  • the filter itself has a cone shape when unexpanded. They are widely commercially available from a variety of manufacturers, one of which is Melitta USA, Inc.
  • Cone-type filters may be formed by folding a filter paper, eg., a triangle shaped filter paper, upon itself along edge 3 (FIG.l), cutting said paper and crimping edge 2 (FIG.l) from point A to arc edge 1 (FIG.l), leaving edge 1 (FIG.l) uncrimped in order to enable to expansion along arc edge 1 (FIG.l) into a cone-shaped filter.
  • FIG. 3 shows two cone filters of different sizes superimposed upon one another.
  • FIG. 2 shows the filter paper as expanded and in a configuration for into which coffee grounds are placed after said filter is placed within a filter support structure, which could itself be located inside of a drip-type coffee machine or directly upon a coffee urn or pot or cup.
  • the cone-type paper coffee filters are typically pressed or folded flat and placed next to one another or on top of one another within a paper box.
  • the dimensions of the box roughly correspond to the depth being based on the number of filters present in the box (collective thickness of filters present); the height of the box being the straight line distance from one point on the circumference of the flat pressed filter to a point directly opposite it (often one side of the flat filter is the one which has been bounded together so as to form the cone shaped filter itself when expanded) and the width of the box actually corresponding to the straight line distance on the flat pressed filter from the bottom of the filter to the top of the filter.
  • the box typically open from the top by way of a paper flap whereby the filters can be retrieved.
  • FIG. 4 illustrates the configuration of the filter and box described above. This box is typically where most people leave their filters when not in use.
  • the prior art provides numerous examples of holders for "basket” type filter holders coffee filters (not cone-type). For example, see US patents 5,097,984 and 5,197,630.
  • cone-type (eg., Melitta-type) coffee filter holders are not sealable and are open to the surrounding environment as, for example, the Melitta disposable paper filter holder made and sold directly by Melitta USA, Inc.
  • the disadvantages of an open holder is that the filters are open to the environment and may become dirty and possibly unusable from contamination in the local, typically kitchen, environment (eg., via dust, dirt, insects, liquids or other means).
  • these filter holders are not designed to be capable of holding cone filters of different sizes, particularly smaller filters, at different times or simultaneously.
  • These prior art filter holders are also not optimally designed to stand in an upright position on their own.
  • the Melitta filter holder is provided with an adhesive tape which permits the filter holder to be stably affixed to an object or wall and thereby not fall down if placed in an upright position when filled with filters.
  • the open to the environment cone-type filter holder marketed by Emsa GMBH is designed to be hung from a supporting rack or bar. This filter is not designed to stand in an upright position on its own.
  • it is designed with an upper surface which curves to correspond only to the curve or arc edge 1 (FIG.l) on a certain size filter which fits exactly within it.
  • cone-type paper coffee filters or holder At present, apart from the paper boxes in which the filters are sold, there are no resealable storage holders for cone-type paper coffee filters or holder or which are stable enough to stand upright on their own.
  • the paper boxes in which the cone type filters are sold are not fully or securely re-sealable as they are also subject to water damage or damage from other liquid spills with resultant possible damage to the filters themselves and the boxes once opened.
  • the paper box which the filters are originally purchased in the store typically comes in very limited colors or color patterns chosen by and trademarked by the manufacturer.
  • cone- type paper coffee filters are available in a variety of sizes and no sealable and/or stable stand-alone filter holder exists which can accommodate all sizes of filters simultaneously in an organized way and which allows easy access to the filters.
  • an object of the present invention to provide a sealable and more durable, cone-type filter holder-dispenser.

  • Coffee is one of the world's most popular beverages. There are numerous ways to serve it and prepare it.
  • One of the most popular ways to prepare at present is via the drip method.
  • coffee grounds (coffee beans ground up into small fragments) are placed into a cone shaped filter (e.g., such as that manufactured by Melitta USA Inc.) or pleated cup shaped filter, typically made of paper or metal, after which hot water is then poured over said coffee grounds.

Description

Coffee Filter Holder
Abstract of the Invention
This invention relates to a holder for paper cone-type coffee filters used with drip-type coffee makers.
Background of the Invention
The prior art provides numerous embodiments of holders/dispensers for paper coffee filters of the non-cone variety, e.g.. pleated basket type. In those constructions the paper filters nest within one another, like the skin of an onion. Each time one is used or dispensed the next one presents itself.
Cone-type paper coffee filters as opposed to basket type filters, however, do not nest within one another prior to use. FIG. 1 illustrates the configuration of a typical construction of a cone-type (e.g., Melitta type) filter described above. The filter itself has a cone shape when unexpanded. They are widely commercially available from a variety of manufacturers, one of which is Melitta USA, Inc. Cone-type filters may be formed by folding a filter paper, eg., a triangle shaped filter paper, upon itself along edge 3 (FIG.l), cutting said paper and crimping edge 2 (FIG.l) from point A to arc edge 1 (FIG.l), leaving edge 1 (FIG.l) uncrimped in order to enable to expansion along arc edge 1 (FIG.l) into a cone-shaped filter. FIG. 3 shows two cone filters of different sizes superimposed upon one another. FIG. 2 shows the filter paper as expanded and in a configuration for into which coffee grounds are placed after said filter is placed within a filter support structure, which could itself be located inside of a drip-type coffee machine or directly upon a coffee urn or pot or cup.
Before being placed on a support structure within a coffee making machine or placed directly above a coffee cup or pot while supported within a filter support structure (or brewing cone) they are expanded to reveal the cone shape within which the coffee grounds are placed.
The cone-type paper coffee filters are typically pressed or folded flat and placed next to one another or on top of one another within a paper box. The dimensions of the box roughly correspond to the depth being based on the number of filters present in the box (collective thickness of filters present); the height of the box being the straight line distance from one point on the circumference of the flat pressed filter to a point directly opposite it (often one side of the flat filter is the one which has been bounded together so as to form the cone shaped filter itself when expanded) and the width of the box actually corresponding to the straight line distance on the flat pressed filter from the bottom of the filter to the top of the filter. The box typically open from the top by way of a paper flap whereby the filters can be retrieved. FIG. 4 illustrates the configuration of the filter and box described above. This box is typically where most people leave their filters when not in use.
The prior art provides numerous examples of holders for "basket" type filter holders coffee filters (not cone-type). For example, see US patents 5,097,984 and 5,197,630. The prior art embodiments for cone-type (eg., Melitta-type) coffee filter holders, however, are not sealable and are open to the surrounding environment as, for example, the Melitta disposable paper filter holder made and sold directly by Melitta USA, Inc. The disadvantages of an open holder is that the filters are open to the environment and may become dirty and possibly unusable from contamination in the local, typically kitchen, environment (eg., via dust, dirt, insects, liquids or other means). In addition, these filter holders are not designed to be capable of holding cone filters of different sizes, particularly smaller filters, at different times or simultaneously. These prior art filter holders are also not optimally designed to stand in an upright position on their own. The Melitta filter holder is provided with an adhesive tape which permits the filter holder to be stably affixed to an object or wall and thereby not fall down if placed in an upright position when filled with filters. Similarly, the open to the environment cone-type filter holder marketed by Emsa GMBH is designed to be hung from a supporting rack or bar. This filter is not designed to stand in an upright position on its own. In addition, it is designed with an upper surface which curves to correspond only to the curve or arc edge 1 (FIG.l) on a certain size filter which fits exactly within it.
At present, apart from the paper boxes in which the filters are sold, there are no resealable storage holders for cone-type paper coffee filters or holder or which are stable enough to stand upright on their own. The paper boxes in which the cone type filters are sold are not fully or securely re-sealable as they are also subject to water damage or damage from other liquid spills with resultant possible damage to the filters themselves and the boxes once opened. Furthermore, the paper box which the filters are originally purchased in the store typically comes in very limited colors or color patterns chosen by and trademarked by the manufacturer. In addition, cone- type paper coffee filters are available in a variety of sizes and no sealable and/or stable stand-alone filter holder exists which can accommodate all sizes of filters simultaneously in an organized way and which allows easy access to the filters.
It is, therefore, an object of the present invention to provide a sealable and more durable, cone-type filter holder-dispenser.
It is also an object of the present invention to provide a cone-type (e.g.., Melitta type) coffee filter holder-dispenser which is stable in the upright position.
It is a further object of this invention to provide a coffee filter holder- dispenser which is capable of holding cone-type coffee filters of different sizes (e.g., size nos. 2, 4 or 6 or the approximate equivalent size 102, 104, 106 ) at the same time.
It is an additional object of this invention to provide a cone-type coffee filter holder-dispenser which presents cone type coffee filters in a manner which facilitates retrieving one filter at a time.
It is an additional object of this invention to provide a cone-type coffee filter holder-dispenser which is available in a wide variety of colors and color patterns. Summary of the Invention
This invention comprises a non-expanded, cone-type paper coffee filter container comprised of a body having sides and a bottom, with the sides and bottom being comprised of a durable material and a cover for engaging the open end of the body and sealing the interior of said body from environmental contaminants such as moisture and dust. The cover is preferably removably attached to the body and has substantially the outline of the shape of a non-expanded cone-type paper coffee filter. The bottom of the body also has substantially the shape of a non-expanded cone-type paper coffee filter. The sides are essentially perpendicular to the horizontal axis of said bottom and follow the outline of the edge of said bottom. The container body is of sufficient size as to accommodate a plurality of non- expanded cone-type paper coffee filters.

Detailed description of the Invention
Coffee is one of the world's most popular beverages. There are numerous ways to serve it and prepare it. One of the most popular ways to prepare at present is via the drip method. In this method, coffee grounds (coffee beans ground up into small fragments) are placed into a cone shaped filter (e.g., such as that manufactured by Melitta USA Inc.) or pleated cup shaped filter, typically made of paper or metal, after which hot water is then poured over said coffee grounds. A liquid which comprises an even finer suspension of coffee particulates and other soluble and insoluble substances from the ground coffee beans passes through the filter into a holding receptacle such as a coffee urn, pot or cup. Depending on the amount of coffee grounds to be used, the volume of the coffee drink intended to be brewed and/or the size of the receptacle and depending if the coffee to be made manually (with a person pouring the hot water over the grounds) or by a coffee machine (with the machine pouring the hot water over the grounds) a different size filter may be used. Such filters are typically given number designations such as 1 , 2, 4, 6 and 8 [or their substantial equivalent size designations 101, 102, 104, 106 or 108; lxl, 1x2, 1x4, 1x6 or 1x8], with the smaller numbers indicating respectively smaller sized filters (having a smaller radius or distance from point A, FIG.l).
The primary difference in size of a filter is primarily the length of the radius from point A at the bottom of said filter (see FIG.l, e.g., the location on the filter where the sides come closest together with the bottom of said filter being in a horizontal/parallel disposition relative to the horizontal/flat surface of a filter support surface) to the top arc edge 1 of said filter (e.g. the portion of said filter which expands to yield the cone shape and from which side said coffee grounds are added to the filter. The angle of the sides of said pressed flat filter can be seen in FIG. 1 wherein angles C and D are both about 50 degrees from the horizontal although the exact angle can be modified as required. The coffee filter holder invention herein can be designed to accommodate any filter angle. The bottom of said filter, as noted above, is typically flat or horizontal as on surface E, however, it may also have rounded corners , point F, or both sides could progress to a central point of said cone. Most filters manufactured for drip use today utilize the flat or horizontal configuration for the bottom as seen in FIG.1. The top edge of said filter has an arc edge shape which, when said filter is fully opened, is capable of taking on a circular or semi-circular configuration (around the upper surface of said filter holder in said coffee maker or holder. The standardization of the angles of said sides of the cone filter allows for standardization of both the filters and the coffee machines which use them. The angles of said filter sides and bottom typically correspond to the angles and bottom configuration on the filter support structures found within said machines and in single-use coffee filter makers.
It a most preferred embodiment the invention herein comprises a holder for non-expanded cone-type paper coffee filters comprising a container having substantially the shape of a non-expanded cone-type paper coffee filter said container being closed on all sides except one and a cover removably attachable to the one open side of said container.
In an example of this preferred embodiment, the coffee filter holder of this invention is constructed in the same manner as are other Rubbermaid or Tupperware (plastic) containers as shown in FIGS. 5, 6, 7 A and 7B. In this embodiment the cone filter holder Jϋ has a snap-on or pressure fit cover or lid 11. This cover and/or container body optionally includes size indicia 12 (eg., No. 2 or 4 size). The filter holder container or body itself 11 is preferably shaped and sized in the form of and so as to retain a cone filter of a particular size. In one embodiment, the cover would be disposed on the container and would be aligned on the side of the filters if they were lying on their side, parallel to the plane of the ground. In another embodiment the cover would be aligned with either the curved arc edge 1 or one of the other sides of the filter if the filters were standing with their edges 2 and 3 perpendicular to the horizontal plain of the ground.
Alternatively, said filter container body may include permanent or temporary inserts which would allow a substantially square or rectangular container body to have inner dimensions which substantially match a desired filter outline.
The filter container body and/or cover may be opaque or transparent or have any desired color, combination of colors or design pattern. The filter container body width or depth could be sufficient to hold an entire box of filters or more or less.
The cover for engaging the open end of said container body and sealing it against moisture and dust could optionally simply rest on a lip edge 14 on the container body as shown in FIGS 7A and 7B, pressure fit on the body as shown in FIGS. 5 and 6, attach by hinge means (and/or optionally include a latch typically opposite said hinge) or be screwed on. Preferably said cover includes a circumferential rib member 13. for engaging said body to releasably secure said cover to said body which fits into a slot 16 formed onto lid 11. The filter holder container body and/or cover can be constructed of any durable material such as plastic, rubber, metal, wood, glass, ceramic, textile, mineral, carbon fiber, glass fiber or any combination of the above.
