Description

Beverage cups for coffee or the like

field of invention

The present invention relates to beverage filter cups or cartridges which are filled or pre-filled by users at their home or shop with flavor containing ingredients such as coffee, tea, cocoa powder or apple juice.

Background of the invention

U.S. Pat. Nos. 5,325,765 and 5,840,189 teach beverage boxes by Sylvan et al. due to their convenience and speed in The (K-Cup) brand has gained widespread acceptance, however several issues have persisted since its introduction some 20 years ago. One such problem is the limited amount of ground coffee that a cartridge can hold, making coffee too inadequate for some people. Sweeney et al. in US Patent No. 6,645,537 teach solving this problem by sealing the filter to a tapered circular rim located in the lower portion of the cup. This problem can also be solved by replacing Sylvan's cone filter with a cup filter 20 in cup 10A shown in FIG. 1A. The top end 17 of the side wall 21 of the filter 20 is connected to the top side wall 16 of the container 19 . The periphery 14 of the cover film 11 is permanently heat sealed to the rim 15 of the container to seal the coffee 12 . An almost 1 inch high empty space 24 is formed below the flat filter bottom 23 to prevent the sharp point 31 of the needle 29 on the top wall 27 of the cup holder 28 from breaking when the cup 10A is fully inserted into the cup holder 28 filter bottom. The needle 29 is designed to pierce the bottom wall 25 for the beverage to flow out via the channel 30 . However, both solutions do not fully utilize the space in the cup for ground coffee due to the high empty space 24 .

Another problem is that Sylvan's cartridge gives the consumer no control over what and how much ground coffee is used. To address this problem, a number of refillable filter cups have been provided, such as the Ekobrew ^™ , Cafe Cup ^™ and Solofill ^™ cups taught by Vu in US Patent Application 2013/0017303. Such a filter cup, indicated as 10B in FIG. 1B , typically has a cup-shaped filter 20 formed in a container 19 with an empty space 24 high enough to prevent the filter bottom 23 from being pierced by a needle 29 . Rigid lid 41 has a rubber O-ring 42 positioned on side wall 43 to seal to side wall 16 of container 19 . An opening 45 is formed at the center of the cover to receive a water injection needle (not shown) from a brewer and a plate 47 having several holes 44 for distributing water from the injection needle to the ground coffee 12 . Although such filter cups allow consumers to use their own ground coffee, such filter cups are also unable to accommodate ground coffee for jumbo or large cups of coffee. Filling and cleaning of such filter cups is also time-consuming and messy, especially in the mornings when coffee and time are equally precious, making The convenience and speed of brewing is nullified.

To make cleaning easier, Simple Cup ^TM offers disposable filter paper that fits into the filter cup. However, the filter paper also reduces the amount of coffee that the filter cup can hold. Simple Cup ^™ also provides a separate container, lid and inverter to allow the user to assemble the filter cup by placing filter paper into the container, filling with coffee, and then pushing the lid firmly into the container with the inverter support. This process is even more difficult and slower than using the filter cup of Figure IB. Furthermore, since there is no seal between the lid and the container in the assembled filter cup, the coffee does not stay fresh and the lid tends to slide off the container causing coffee grounds to splatter here and there during disposal and storage.

The first object of the present invention is to provide a new drinking glass which is not only convenient and quick to be used as And also give consumers the freedom to choose their own roast, brand and amount of ground coffee as enabled by the refillable filter cup.

A second object of the present invention is to provide a new drinking glass that allows consumers such as Or fill up to 50% more ground coffee like a refillable filter cup.

A third object of the present invention is to provide new drinking cups, compared to cost, the beverage cup can save up to at least 50% of the cost.

A final object of the present invention is to provide new cups which are reusable when the user desires greater cost savings and which are disposable when the user desires greater convenience.

Summary of the invention

The beverage cup or cartridge of the present invention comprises an impermeable cup-shaped container having a flat bottom wall pierceable by a beverage outlet needle in the cup holder of the brewer, and a cup-shaped filter. The container has a flat filter bottom supported on the flat bottom wall or positioned close enough to the flat bottom to allow a needle to push a portion of the flat filter bottom upward to form a beverage collection chamber . Unlike the large and tall built-in beverage collection chambers in prior art K-cups or reusable filter cups, the beverage collection chamber of the present invention does not exist prior to the brewing operation, allowing the beverage cup of the present invention to hold up to 50% more ground coffee. The beverage cup also includes a lid having an outer side wall that is smaller than the opening of the cup-shaped container to allow the lid to move almost freely in and out of the container to facilitate closure of the container, and a pressure sensitive adhesive. An annular ring is positioned between the horizontal peripheral wall of the lid and the horizontal rim of the cup-shaped container. The cup-shaped container and lid are made of very thin walls to minimize the use of material and make the cup disposable and reusable according to each user's wishes. The lid also includes sloped inner sidewalls to convert brewing pressure in the cup into a radially outward force on the outer sidewall of the lid to give the thin walled lid strength and rigidity to resist Deformation of the outer side wall of the cover, thereby preventing hot water from leaking.

In an alternative embodiment, the drinking glass further comprises an annular pressurized chamber enclosed by an outer side wall, an inner side wall and a top membrane sealed to the lid. The pressurized chamber is at ambient pressure prior to brewing, and when hot water is injected into the drinking cup through the water inlet needle of the brewer, the pressurized chamber becomes pressurized and expands in volume, giving the thin wall The cap is rigid and acts as an O-ring to improve the seal of the container.

Description of the preferred embodiment

As shown in FIGS. 2-2B , the beverage filter cup or cartridge 100 of the present invention includes an impermeable container 19 , a filter 170 and an impermeable lid 122 . For simplicity, parts similar to those in the prior art drawings of FIGS. 1A and 1B have been assigned the same reference numerals. The container 19 is preferably cup-shaped and has a tapered frusto-conical impermeable lower side wall 22, an impermeable upper side wall 16, a step 18 between the lower side wall and the upper side wall, a beverage outlet through A generally flat impermeable bottom wall 25 piercable by needles 29, and a radially outwardly projecting edge 15 surrounding a circular entry opening for receiving flavor-containing material 12 such as ground coffee, tea, cocoa powder Or other raw materials containing fragrance. The outlet needle is located at the bottom 27 of the holder 28 of the brewer and has a sharp point 31 for piercing the bottom wall 25 and a beverage outlet channel 30 .

As shown in FIGS. 2 and 2B , the filter 170 is cup-shaped and includes an upper filter side wall 177 permanently connected to the inner surface of the upper side wall 16 , a lower filter side wall 171 and a closed generally The upper flat filter bottom 173 defines a storage chamber for storing the raw material 12 containing fragrance. Unlike the filter bottom 23 of the prior art filter 20 shown in FIGS. A substantially flat elastomeric film 111 on or sufficiently close to the bottom 25 of the container 19, thus maximizing the volume or capacity of the storage chamber for containing the raw material 12 containing the fragrance. The results indicate that the reservoir of the beverage filter cup 100 can hold up to 50% more flavor-containing material 12 than the prior art filter cups 10A and 10B shown in FIGS. 1A and 1B .

Unlike the large and tall built-in beverage collection chamber 24 in the prior art K-cup 10A or reusable filter cup 10B shown in FIGS. 1A and 1B , the beverage collection chamber 100 of the present invention is inserted into the filter cup 100 It hardly exists until it reaches the holder 28 . The beverage collection portion 110 is formed in the filter cup 100 when the bottom wall 25 of the container 19 is pierced by the outlet needle 29 and the outlet needle pushes a portion of the filter bottom 173 upwards. As more of the needle 29 pierces the bottom wall 25 , the collection chamber 110 increases in size and reaches a maximum size after the cup 100 is fully inserted into the holder 28 . The elastomeric membrane 111 renders the filter bottom 173 puncture resistant to the exit needle. Other puncture resistant sheets, flexible or rigid, such as polyolefin sheets or non-woven polypropylene films, may be attached to the filter bottom 173 to render the filter bottom puncture resistant.

The results show that when a particular selected material is used for the filter 170 and container 19, after the filter is sealed to the upper side wall 16 of the container via heat, ultrasound, infrared or other energy, the upper filter side wall 177 become invisible. This invisibility of the filter improves the seal between the container 19 and the lid 122, makes filling and cleaning the beverage cup easier and makes the cup look better. Known cup materials, such as polystyrene or polymer laminates, such as the Winpak Portion Pack of Bristol, Pa., product number C150 taught by Sylvan et al. in U.S. Patent Nos. 5,325,765 and 5,840,189, do not The upper filter side wall 177 is not visible. The results also show that in order to achieve this invisibility, the filter 170 should also be made of the same or similar material as the container 19 . Materials satisfying such conditions are polyethylene and polypropylene. The lower filter side wall 171 is corrugated to facilitate the flow of beverage out of the closed chamber bounded or formed by the filter bottom 173 , filter side wall 171 and lid 122 . Vertical channels (not shown) may be formed on the lower side wall 22 and channels (not shown) may be formed on the bottom wall 25 of the container to improve beverage flow to the beverage collection chamber 110 .

The lid 122 comprises a peripheral horizontal wall 115 above the rim 15 of the container, an impermeable central wall 127 piercable from the brewer by a water injection needle (not shown) for introducing water into the container, and A circular channel 121 between the peripheral and central walls. The circular channel 121 includes a first outer cap side wall 117 receivable in the access opening defined by the top side wall 16 of the container, a second outer cap receivable in the upper portion of the side wall 22 just below the step 18 The side wall 119, the stepped wall 118 connecting the first and the second outer side wall, the inner side wall 120 having one end connected to the central wall 127 and the other end connected to the second outer side wall 119, and the container 19 The edge 15 of the cover is connected to three flexible thin connectors or beams 114 of the peripheral wall 115 of the cover. Spaces 112 are formed between flexible beams 114 .

Unlike the prior art disposable K-cups in FIG. 1A , where the cover film 11 is permanently heat-sealed to the container 19 , and unlike the thick, rigid walls and rubber O-rings that can be provided for blistering under high pressure In order to prevent leakage during manufacture of the reusable filter cup in FIG. 1B , the cap 122 of the present invention needs to use a disposable thin wall as thin as 0.01 inches as desired by the user, and needs to be removable to allow the user to Add ground coffee to container. As a result, the lid 122 is prone to hot water leakage during brewing due to the thin lid walls of the lid 122 being very easily deformed under high brewing pressures. In order to improve the seal between the lid 122 and the container 19, the inner side wall 120 is sloped, preferably at an angle of less than 60 degrees relative to the first outer side wall 117 . Such a sloping inner side wall 120 converts the brewing pressure inside the cup 100 into an outward radial force acting on the lower end of the first outer wall 117 to improve the rigidity of the thin walled lid 122 and side wall 117 and the seal between the side wall 16. The second outer side wall 119 is provided to further improve the seal between the lid and the container during brewing.

Unlike the prior art cup 10B of FIG. 1B which uses a rubber O-ring 42 on the side wall 43 to achieve a seal, as shown in FIG. A pressure sensitive adhesive O-ring 116 on the underside of the horizontal peripheral wall 115 . When the lid 122 is turned by the connector 114 and placed on the container 19 , the pressure sensitive adhesive O-ring 116 adheres readily to the rim 15 of the container 19 . By having the pressure sensitive adhesive o-ring on the horizontal peripheral wall 115, even the first outer lid side wall 117 is substantially smaller than the inner diameter of the upper side wall 16 or the top access opening of the container 19, for example 0.04 to 0.2 inches smaller , and no leakage was observed during pressure brewing. Since the lid side walls 117 are smaller than the top access opening, little or no force is required to press the lid into the container after the user has filled the cup with ground coffee, making the sealing operation effortless.

A lid with a lid sidewall 117 that is smaller than the top entry opening is also critical to the successful preparation of the beverage cup when the consumer fills and seals the cup at home. Because the cup 100 is disposable, the sidewalls 16, 22 of the container 19 are also very thin, eg, thinner than about 0.03 inches. If the lid sidewall 117 is approximately the same as or larger than the top opening of the container 19, such thin sidewalls cannot withstand the force required to press the lid sidewall 117 into the top access opening. A cap with a smaller side wall 117 can be pressed into the top access opening with little or no force so that when the user presses the cap into the container to seal the Or the ground coffee 12 in the storage chamber formed prevents the container 19 from collapsing.

Although the beverage cup 100 uses a very small amount of material by using a very thin-walled lid 122 and container 19, and can be used as Disposable, but more cost- or environmentally conscious users may still wish to reuse beverage cup 100 . In order to allow a person to reuse the cup 100, we found that by using a hydrophilic pressure sensitive adhesive to make the O-ring, the O-ring may lose its adhesiveness after the brewing operation. Such loss of cohesion after brewing makes it possible for the user to open the lid, dispose of the used grounds and clean the cup 10 for repeated use. After the cup 10 becomes dry in air or by heat, the pressure sensitive adhesive O-ring regains its adhesive force to bond and seal the lid to the container 19 .

The pressure-sensitive adhesive used to make the O-ring 116 can be a pressure-sensitive hot melt such as FIMA-221-A from the glue factory in Germantown, Wisconsin, or a pressure-sensitive hot melt such as AA-4080 from the same factory. Sensitive emulsion. The results show that for the cup 100 to work, the pressure sensitive adhesive O-ring 116 needs to have a height of about 0.1 mm to 2 mm, preferably 0.2 mm to 1 mm. As shown in FIG. 2B , the inner perimeter of the pressure sensitive adhesive O-ring 116 is positioned near or at the outer sidewall 117 to prevent the O-ring after the lid is sealed to the container 19 and then removed from the container. The ring falls or is transferred to the edge 15 of the container. Various textures, roughnesses, protrusions, recesses, channels, and ridges can be provided on the underside surface, wherein the pressure sensitive adhesive O-ring is positioned to then prevent the O-ring from dislodging from the surface during sealing and removal of the cap. The underside surface falls off or transfers to the edge. The pressure sensitive adhesive O-ring 116 does not require a release or protective paper. When the O-ring 116 is soiled by ash or coffee particles, it can be easily cleaned with rinse water to cause the O-ring to lose its cohesion, and the O-ring can then be rebuilt by allowing it to air dry. Get its adhesive power.

Containers 19 and lids 122 with thin walls may be thermoformed from thin plastic sheets. Although in the preferred embodiment the beverage cup 100 has a round cup shape, it should be understood that the cup may take oval, square, rectangular, diamond and other shapes. It should be understood that pressure sensitive adhesive O-rings may take shapes other than circular and may be used in other applications. It should also be understood that if the flavor-containing ingredient 12 is cocoa powder, milk powder, soup powder, apple juice, or any edible substance that can be consumed with or without the addition of water, the cup can be used without the need for a filter 20.

3-3B illustrate an improved embodiment of the beverage cup 100 of FIG. 1 . The modified cup has a generally annular pressurized chamber 162 which is receivable in the access opening of the container 19 and connected to a lid for preventing leakage during brewing. The pressurized chamber comprises an outer side wall 117 of the lid for engaging the impermeable upper side wall 16 of the container 19, an inner side wall 120 of the lid which contacts the hot fluid during brewing, a top membrane ring 161 and connections to the inner and outer side walls. The chamber bottom 118 of the wall. The pressurized chamber is at ambient pressure prior to brewing, and when hot water injected into the cup 100 from the brewer's water injection needle (not shown) heats the air in the chamber, the pressurized chamber is period becomes pressurized. The pressure in this pressurized chamber pushes the outer side wall 117 radially outward to improve the sealing of the upper side wall 16 of the container 19 and to impart rigidity to the thin walled lid 122 . Membrane ring 161 is part of a generally circular membrane 167 and is heat sealed to the top end of outer sidewall 117 . The outer peripheral section 160 of the membrane 167 is sealed to the peripheral wall 115 of the cover 122 . Membrane ring 161 may also be heat sealed to the top end of inner wall 120 to create an annulus airtight to allow pressure to build up in it as hot water from the water inlet needle heats the air in the annulus and prevents it from burning above the fragrance containing material. The hot fluid enters the annular chamber.

The cup filter 170 is made of non-woven polypropylene and the container 19 and lid 122 are also made of polypropylene so that the consumer can reuse all the acrylic material in the filter and container after rinsing out the used coffee grounds. In order to make the beverage cup fully reusable, it was found that when the non-woven filter is made of elongated, long polymer fibers of polyolefin, polyester, nylon, or similar polymers, the beverage collection chamber 110 may not be attached to the filter. The elastomeric membrane 111 of FIG. 2 is formed of a flat bottom 173 .

A protective opening 163 is formed at or near the center of the impermeable central wall 127 to prevent the beverage cup 100 from sticking to the brewer's bubble when the user opens the brew head to dispose of the used beverage cup. head (not shown) and cause damage to the brewer. This protective opening is covered by a central membrane 164 of membrane 167 to prevent oxidizing air from reaching the feedstock 12 after the lid 122 is sealed to the container 19 . In order to prevent water leakage during brewing, in an alternative embodiment of the invention (not shown), the protective opening is made at least 3 times larger in diameter than that shown in FIG. 3 . In the alternative embodiment, the enlarged protective opening 163 occupies at least 40% of the area of the impermeable central wall 127 .

One problem with the beverage cup 100 of FIG. 2B is that the lid 122, although very light in weight, typically less than 5 grams, often causes the container 19 to tip and fall when the user places the beverage cup on a table or countertop, which This makes filling the cup with ground coffee inconvenient and difficult. One solution is to provide a separate container 19 and lid 122, however this requires the user to store and handle two separate parts. An improved solution is shown in FIG. 3B , wherein one end of the cover 122 is connected to the rim 15 of the container 19 via a section of a low-memory membrane connector 168, and to the connected end. The opposite free end has approximately the same height as the bottom 25 of the container 19 . This allows the free end of the lid 122 to rest on the table or countertop when the beverage cup is placed on the table or countertop. The low memory film connector 168 has a small amount of memory of its previous shape and can be an aluminum foil or paper based film that can retain its current shape independent of its previous shape or can be free to bend with a weight of the cover 122 that is less than 5 grams ultra-flexible membrane. To prevent lid 122 from moving out of the access opening of container 19 , the length of membrane connector 168 is generally greater than the combined thickness of rim 15 and outer peripheral wall 115 .

To use, one grinds 1/4 to 1 pound of one's favorite brand of freshly roasted coffee beans, and places 12 to 48 beverage cups 100 on a table or countertop such that the free end of lid 122 is also supported on On a table or countertop, 8 to 15 grams of ground coffee is dispensed or scooped into each cup, depending on one's preference for coffee strength and volume, and the lid 122 is flipped over the container 19 to cause the pressure sensitive adhesive O-shaped The ring 116 hermetically seals to the rim 15 of the container to keep the ground coffee fresh. Such a prefilled coffee mug 100 can be in the back like use the same.

4 and 4A show a second modified embodiment of the beverage glass 100 of FIG. 2 . In the improved cup, the radially outwardly projecting peripheral wall or edge 115 outside the first outer lid side wall 117 of the lid 122 is shortened so that the width of the shortened edge 115 is substantially wider than the edge of the cup-shaped container 19. 15 narrow. The lid 122 is heat sealed to the flexible membrane 167 and connected to the container 19 by heat sealing a small portion 181 of the membrane 167 to a portion of the rim 15 . The outer peripheral section 160 of the membrane 167 extends outwardly to cover the rim 15 of the container 19 when the container is sealed. The flexible outer peripheral section 160 of the membrane 167 resists accidental opening when the cup 100 is dropped on a hard floor or contacts other objects. Moreover, the flexible outer peripheral section 160 prevents any possible tampering with the contents of the cup, because when a person tries to pull the flexible outer peripheral section 160 to open the lid 122, the membrane will be heat sealed to the lid 167 at its Or break near its heat seal to lid 167, which renders cup 41 unusable and acts as a warning signal that the cup has been tampered with. However, during brewing, steam heat or water makes the lid 122 removable after the cup 100 has been brewed, which makes it possible to reuse the cup or remove spent ground coffee for better reuse.

A recess 180 is formed on the rim 15 around the access opening of the container 19 and is sized to receive the shortened rim 115 such that the bottom surface of the shortened rim 115 is substantially below the top surface of the cup rim 15 . The results show that when the recess 180 is deep enough to cause the top surface of the shortened rim 115 to be at least approximately coplanar with or even below the top surface of the rim 15 of the container 19, the adhesion increases significantly to This makes opening the lid 167 nearly impossible unless the cup 100 is infused with hot water in the infuser.

The results also show that by making the diameter of the protective opening 163 larger than one-third of the diameter of the cover 122, preferably larger than half the diameter of the cover, the freshness and aroma of the ground coffee sealed in the cup 100 is between 3 and 6 hours. The storage time of months was greatly improved afterwards. Theoretically, the larger opening 163 prevents air from entering the chamber as room temperature or chamber pressure varies during the day and night. It has also been found that the freshness and aroma of the ground coffee sealed in the cup 100 is greatly enhanced by making the adhesive O-ring 116 sufficiently fluid to cause the adhesive to wick when the container 19 is closed by the lid 122. Great improvement. It has also been found that the freshness and aroma of the ground coffee sealed in the cup 100 is greatly improved when the adhesive O-ring 116 comprises a layer of adhesive on the outer surface of the first outer lid side wall 117 .

It was found that even though the lid 122 was not heat sealed to the flexible membrane 167 , the cup 100 of FIGS. 4 and 4A still worked without water leakage during brewing, as shown in FIG. 5 . The flexible outer peripheral section 160 of the membrane 167 is connected to the container 19 by heat sealing a small portion 181 of the membrane 167 to a portion of the rim 15 of the container 19 . The flexible membrane 167 should be sufficiently rigid to form a proper fill and seal angle Φ for the cup. The angle Φ should be between 90° and 265° to enable proper filling and sealing of the cup by the coffee filling equipment. The peripheral section 160 of the membrane 167 is sealed to the edge 15 by an adhesive O-ring 160 or heat seal. The filter bottom 173 is generally flat and sufficiently close to or even touching the bottom wall 25 of the container 19 to form a particularly large containment chamber formed by the pleated side filters 171 and the closed bottom filter 173 or filter chamber. The beverage collection chamber 110 has zero or near zero volume, but is adapted to expand in volume during brewing to facilitate the extraction of the ingredients in the filter chamber and the beverage out of the cup.

It should be appreciated that by positioning the colander bottom 173 close to or in contact with the cup bottom 25, the present invention has avoided the The "water channeling" problem in , water channeling occurs because the water sprayed from the brewer creates a large central path between the water inlet needle in the brewer and the bottom 23 of the filter and causes Most of the brewer's water passes directly through the filter bottom 23 (FIGS. 1A and 1B) without touching the ground coffee. It should also be appreciated that the beverage filter cup 100 may take on a square shape to reduce its need for storage and transport space. It should also be understood that the beverage outlet needle 29 may be solid without the channel 30 and the beverage outlet formed between the outer surface of the needle and the piercing hole at the bottom 25 of the container 19 .

Although specific features of the invention are shown in some drawings and not in others, this is for convenience only, as some features may be combined with any or all other features in accordance with the invention. The foregoing description has been limited to specific embodiments of the invention. It will be apparent, however, that variations and modifications may be made to the invention so as to obtain some or all of the advantages of the invention. It is therefore the intention in the appended claims to cover all such changes and modifications as are within the true spirit and scope of the invention.
