Definitions
- This invention relates to a drinking cup assembly having an outer cup with handles and an inner cup to hold a product.
- the drinking cup assembly is primarily directed for use with infants and small children.
- each of the outer and the inner cup can be used separately with each having a separate lid for closing the assembly units when used separately.
- An objective of the invention is to have a multi-use drinking cup assembly for use in providing both liquid and solid nutrition to an infant or child.
- Many parents of infants and small children will have two or more cups, such as “sippy” cups, available for use. This is the case if more than one type of liquid is to be provided to the infant or small child away from home. Also in the home more than one cup is needed since one may be in the process of being washed while another is in use. With the cups being versatile and useful with both liquid and dry food, additional needs are served with fewer units. Cups such as “sippy” cups for liquids are shown in U.S. Pat. No. 5,273,172; U.S. Pat. No. 7,124,907 and U.S. Design Pat. 649,835.
- U.S. Pat. No. 5,273,172 discloses a cup for a liquid that has a closure with a straw that can be closed by a lid on the closure rotating and bending the straw. The sole use for this cup is for liquids.
- U.S. Pat. No. 7,124,907 discloses a related cup for liquids where the straw is closed in a manner similar to that of U.S. Pat. No. 5,273,172, but where the closure has a channel to accommodate the straw when it is being bent over by a lid to close the straw.
- 7,124,907 also discloses the placement of a graphical expression in a cavity between an inner and an outer cup. This cup also is solely for use with liquids.
- U.S. Design Pat. 649,835 discloses a Sip Cup that has a closure and two handles. This can be used by an infant or a child.
- the present invention solves many problems. It provides a multi-use “sippy” cup. It provides a more useful dual cup assembly.
- the use of the cups individually with separate lids makes them useful to also store solid as well as liquid products. As the child grows the cup closure with a straw may no longer needed. Then the cups with lids can be used to carry treats or to store many kitchen items.
- the inner cup may be used as a tumbler for toddlers or older children, extending the usability of this cup. Used together the cups serve as an instrument that can be personalized to the user by the addition of inserts between the inner and the outer cups making it a distinct advantage from other “sippy” cups.
- the invention is directed to a drinking cup assembly comprising an outer cup and an inner cup, the outer cup having a dispensing closure, the inner cup removably attached to the outer cup with a space between the outer cup and the inner cup, an item being insertable into the space.
- the item being one or more of informational, decorative and/or insulating.
- the dispensing closure has an aperture adapted to receive a flexible conduit straw and a rotatable lid to open and close the flexible conduit.
- the outer and inner cups are each structured to receive a sealing lid to separately close the outer cup and the inner cup so that they can be separately used.
- the lid for the outer cup can also be used to seal the combined unit of inner and outer cup with a single seal for ease of use.
- the outer cup has handles for enhanced gripping by an infant or child.
- the attachment of the lids may be by one of an interference fit and a threaded attachment to the open peripheral end of the inner and the outer cups and usually will include a lid sealing gasket.
- the closure has a recess adjacent to the aperture, the flexible conduit straw fitting within this recess upon the rotatable lid being rotated and flexing the conduit to close the conduit.
- the weighted lower end of the flexible conduit straw is comprised of a relatively soft plastic or of a relatively hard material coated with a relatively soft material.
- the inner cup can be metallic comprised of aluminum or a stainless steel.
- the inner cup also can be comprised of a Pyrex glass or a plastic such as a polyester, a co-polyester, a polyolefin such as polypropylene, or a combination of materials such as a silicone layer on an aluminum or a stainless steel. This combination of materials may aid in providing an additional seal on the outer rim of the inner cup to protect the space between the two cups from liquids and also to provide an additional gripping area for infants and toddlers should the toddler use the inner cup as an individual cup.
- the closure of the drinking cup assembly has a valve to equalize the pressure within the drinking cup assembly and the atmosphere outside the drinking cup assembly.
- the valve is an integral part of a sealing gasket between the outer cup and the closure.
- the inner cup has a compressible band on an exterior surface adjacent an open end to hold the inner cup within the outer cup when a part of the two cup drinking cup assembly.
- the flexible conduit straw can be comprised of a plurality of parts. These can be an enlarged upper end, a straw conduit mid-section and a weighted lower end.

- This weighted lower end 29 has at least one opening, usually a lower opening.
- This weighted lower end 29 preferably is comprised of a relatively soft material such as a silicone or a lower molecular weight polyester, polyethylene or polypropylene. These lower molecular weight materials are softer than higher molecular weight materials. It must be of a softer (less hard) material than the walls of both the outer and the inner cups. It can be a higher molecular weight polyethylene or polypropylene, which usually will be harder material, if coated with a soft material. It can also be a metal or metal alloy if coated with a soft material. Any such soft materials must qualify as a food grade material.
- the reason for the preferred material is to prevent the cracking of the lower part of cup 12 or of cup 30 during vigorous shaking and use. If the lower weight end 29 of the flexible conduit straw 28 is of a relatively hard material, or of an uncoated relatively hard material, there is a tendency of the weighted end 29 to cause cracks to form in the cup side walls. This will result in leakage of contained liquid from the cup 12 or the cup 30 depending which is being used to contain the liquid. This can be a leakage from inner cup 30 into outer cup 12 , or if there if the liquid is in outer cup 12 to an exterior surface that will require cleaning. The cracking can occur with sustained shaking of the drinking cups by a child and the consequent striking of the straw lower end 29 against the surfaces of the cup containing the liquid.
- the lower end weight material or weight material coating should be softer (less hard) than the surfaces of both the outer and inner cup surfaces.
- An alternative is to have the inner surfaces of the outer and inner cups comprised of a soft material. However, such cups would be less durable. Coating the inner surfaces of the cups with a soft material also is not an effective alternative.

- a sleeve or other structure can be used to keep the parts in an abutting structure.
- the outer cup 12 will usually be a plastic and preferably a polyolefin. Suitable polyolefins are polyethylenes and polypropylenes. Polyester plastics also can be used. Suitable polyesters are the polyethylene terephthalates. This outer cup 12 also can be transparent or opaque. Suitable transparent plastics are polyesters and certain polypropylenes, such as clarified polypropylenes.
- the inner cup can be a plastic or can be metallic. If a plastic it will usually be a polyolefin or a polyester or copolyester. Useful polyesters or copolyesters are available from the Eastman Chemical Company of Kingsport, Tenn. If metallic it will be an aluminum alloy or a steel alloy, such as a stainless steel.
- Metals are useful since they are not prone to staining. Infant and child drinks can be a grape, cranberry or a related colored fruit. In addition metal cups are easier to clean and are unbreakable. It also is an option to use a glass, such as a Pyrex glass.
- the outer cup and the inner cup can be of essentially any color. This particularly is the case with the outer cup.
- These items can be a person's name, a drawing, an outdoor scene, a picture, a schedule notice, an insulating material or a combination of the foregoing. The possibilities are limitless.
- the closure 16 will be comprised of a polyolefin such as a polyethylene or a polypropylene. It can be opaque, translucent or transparent. In some instances the rotating lid 18 of the closure 16 can be the same or a different color from that of the remainder of the closure.

Description
- This application is a continuation-in-part of U.S. Application 61/796,061 filed Nov. 1, 2012 which is incorporated herein in its entirety.
- This invention relates to a drinking cup assembly having an outer cup with handles and an inner cup to hold a product. The drinking cup assembly is primarily directed for use with infants and small children. Although primarily designed for use together with a single lid that is designed for use with a single lid that is designed to seal and secure the contents of the cup while used as a single cup or a double cup, each of the outer and the inner cup can be used separately with each having a separate lid for closing the assembly units when used separately.
- An objective of the invention is to have a multi-use drinking cup assembly for use in providing both liquid and solid nutrition to an infant or child. Many parents of infants and small children will have two or more cups, such as “sippy” cups, available for use. This is the case if more than one type of liquid is to be provided to the infant or small child away from home. Also in the home more than one cup is needed since one may be in the process of being washed while another is in use. With the cups being versatile and useful with both liquid and dry food, additional needs are served with fewer units. Cups such as “sippy” cups for liquids are shown in U.S. Pat. No. 5,273,172; U.S. Pat. No. 7,124,907 and U.S. Design Pat. 649,835. These patents illustrate the state of the art in cups, such as “sippy” cups, for providing liquids to infants and children. U.S. Pat. No. 5,273,172 discloses a cup for a liquid that has a closure with a straw that can be closed by a lid on the closure rotating and bending the straw. The sole use for this cup is for liquids. U.S. Pat. No. 7,124,907 discloses a related cup for liquids where the straw is closed in a manner similar to that of U.S. Pat. No. 5,273,172, but where the closure has a channel to accommodate the straw when it is being bent over by a lid to close the straw. U.S. Pat. No. 7,124,907 also discloses the placement of a graphical expression in a cavity between an inner and an outer cup. This cup also is solely for use with liquids. U.S. Design Pat. 649,835 discloses a Sip Cup that has a closure and two handles. This can be used by an infant or a child.
- The present invention solves many problems. It provides a multi-use “sippy” cup. It provides a more useful dual cup assembly. The use of the cups individually with separate lids makes them useful to also store solid as well as liquid products. As the child grows the cup closure with a straw may no longer needed. Then the cups with lids can be used to carry treats or to store many kitchen items. The inner cup may be used as a tumbler for toddlers or older children, extending the usability of this cup. Used together the cups serve as an instrument that can be personalized to the user by the addition of inserts between the inner and the outer cups making it a distinct advantage from other “sippy” cups.
- The invention is directed to a drinking cup assembly comprising an outer cup and an inner cup, the outer cup having a dispensing closure, the inner cup removably attached to the outer cup with a space between the outer cup and the inner cup, an item being insertable into the space. The item being one or more of informational, decorative and/or insulating. Between the dispensing closure and the outer cup there is a sealing gasket. The dispensing closure has an aperture adapted to receive a flexible conduit straw and a rotatable lid to open and close the flexible conduit.
- The outer and inner cups are each structured to receive a sealing lid to separately close the outer cup and the inner cup so that they can be separately used. The lid for the outer cup can also be used to seal the combined unit of inner and outer cup with a single seal for ease of use. The outer cup has handles for enhanced gripping by an infant or child.
- The attachment of the lids may be by one of an interference fit and a threaded attachment to the open peripheral end of the inner and the outer cups and usually will include a lid sealing gasket.
- The closure has a recess adjacent to the aperture, the flexible conduit straw fitting within this recess upon the rotatable lid being rotated and flexing the conduit to close the conduit. The weighted lower end of the flexible conduit straw is comprised of a relatively soft plastic or of a relatively hard material coated with a relatively soft material.
- The inner cup can be metallic comprised of aluminum or a stainless steel. The inner cup also can be comprised of a Pyrex glass or a plastic such as a polyester, a co-polyester, a polyolefin such as polypropylene, or a combination of materials such as a silicone layer on an aluminum or a stainless steel. This combination of materials may aid in providing an additional seal on the outer rim of the inner cup to protect the space between the two cups from liquids and also to provide an additional gripping area for infants and toddlers should the toddler use the inner cup as an individual cup.
- The closure of the drinking cup assembly has a valve to equalize the pressure within the drinking cup assembly and the atmosphere outside the drinking cup assembly. In a preferred embodiment the valve is an integral part of a sealing gasket between the outer cup and the closure. In addition the inner cup has a compressible band on an exterior surface adjacent an open end to hold the inner cup within the outer cup when a part of the two cup drinking cup assembly.
- The flexible conduit straw can be comprised of a plurality of parts. These can be an enlarged upper end, a straw conduit mid-section and a weighted lower end. Connector units also can be used to connect one or more of the plurality of parts. One or more of these plurality of parts can include a crosscut structure to preclude leakage up the straw.

There is aband 32 for interference attachment to thesidewall surface 12 a ofouter cup 12 and for contact with theinner cup 30 and for stabilizing theinner cup 30 inouter cup 12. Theband 32 is attached mechanically or adhesively to theinner cup 30. A rolled overedge 34 of the band serves to stabilizeband 32 and to assist in gripping theouter cup 12. Located in a space 36 (seeFIG. 7 ) between theouter cup 12 and theinner cup 30 is an informational, decorative and/or insulatingitem 40 which is shown in this Figure with a caricature of a dog and a slogan. Thegasket 42 is between theouter cup 12 and theclosure 16 and provides a leak proof seal between these parts. - The
closure 16 has abase portion 24 and anupper region 26. There are grippingtabs 25 onclosure 16 to assist in removing the closure from theouter cup 12. The rotatinglid 18 has agripping tab 19 and ahinge 20 to assist in rotating the lid. Extending into theouter cup 12, orinner cup 30, is theflexible conduit straw 28 with a weightedlower end 29 the flexibleconduit straw mid-section 28 b. The weight maintains the flexible conduit straw adjacent to thelower surface 11 ofouter cup 12 orlower surface 35 ofinner cup 30, depending on the cup being used, and within a contained liquid. When used in a single cup version solely in conjunction with theouter cup 12 the flexibleconduit straw weight 29 will be adjacent to thebottom wall 11 of theouter cup 12. When use in conjunction with theinner cup 30 withinouter cup 12 the flexible straw weight will adjacent to inner cuplower wall 35. This single cup version may be used in instances where the user may prefer a lighter weight cup or a larger capacity cup. Thestraw 28 is shown in more detail inFIG. 12 . There is a center sectioncontinuous channel 28 a to and through the weightedlower end 29. Theupper part 33 of theflexible conduit straw 28 has a larger diameter in order to simulate a nipple. A lower section of expandedportion 33 of theflexible conduit straw 28 mounts and seals the flexible conduit straw toaperture 21 of theclosure 16. - This weighted
lower end 29 has at least one opening, usually a lower opening. This weightedlower end 29 preferably is comprised of a relatively soft material such as a silicone or a lower molecular weight polyester, polyethylene or polypropylene. These lower molecular weight materials are softer than higher molecular weight materials. It must be of a softer (less hard) material than the walls of both the outer and the inner cups. It can be a higher molecular weight polyethylene or polypropylene, which usually will be harder material, if coated with a soft material. It can also be a metal or metal alloy if coated with a soft material. Any such soft materials must qualify as a food grade material. The reason for the preferred material is to prevent the cracking of the lower part ofcup 12 or ofcup 30 during vigorous shaking and use. If thelower weight end 29 of theflexible conduit straw 28 is of a relatively hard material, or of an uncoated relatively hard material, there is a tendency of theweighted end 29 to cause cracks to form in the cup side walls. This will result in leakage of contained liquid from thecup 12 or thecup 30 depending which is being used to contain the liquid. This can be a leakage frominner cup 30 intoouter cup 12, or if there if the liquid is inouter cup 12 to an exterior surface that will require cleaning. The cracking can occur with sustained shaking of the drinking cups by a child and the consequent striking of the strawlower end 29 against the surfaces of the cup containing the liquid. As a general rule the lower end weight material or weight material coating should be softer (less hard) than the surfaces of both the outer and inner cup surfaces. An alternative is to have the inner surfaces of the outer and inner cups comprised of a soft material. However, such cups would be less durable. Coating the inner surfaces of the cups with a soft material also is not an effective alternative. -
FIG. 3 is a side elevation view of the completedrinking cup assembly 10. The right and left elevation views are essentially the same. There is shownouter cup 12 withbase 13 and handles 14. Also shown isinner cup 30 withinner cup base 35. Attached to theouter cup 12 at an upper end is theclosure 16. Theclosure 16 hasgrips 25 on thebase 24 of the closure. Rotatinglid 18 haslid grip 19 for raising and closing the lid. Also shown, and better shown inFIG. 6 , isvalve 44 for equalizing the pressure within thedrinking cup assembly 10 with the exterior atmosphere.FIG. 4 is a front elevation view andFIG. 5 a rear elevation view. The only significant difference in these latter two views is in theclosure 16. InFIG. 4 there is shown the front of therotating lid 18 withlid grip 19 while inFIG. 5 there is shownlid hinge 20 andpressure equalization valve 44. Otherwise there is shownouter cup 12 with itsbase 13. There is ahandle 14 on each side with each handle having handle grips 17. Theclosure 16 has abase 24 and anupper region 26.

The rotatinglid 18 is onupper region 26 and is attached to theupper region 26 athinge 20. The lid has alid grip 19 to assist in opening the lid. -
FIG. 7 is a vertical cross-section of thedrinking cup assembly 10 without theclosure 16. There is shown theouter cup 12 withhandles 14, abase 13 and alower surface 11. Also shown arethreads 15 which mate with threads on theclosure 16 to attachclosure 16 toouter cup 12. Handle grips 17 are shown on an inner surface of thehandles 14. Theinner cup 30 is shown with a rolled overtop edge 34. Thisinner cup 30 has aside wall 31 and abottom wall 35. Attached to an upper end ofinner cup 30 isband 32 to provide for a friction fit ofinner cup 30 inouter cup 12. Thisband 32 can be mechanically or adhesively attached to theinner cup 30. This band preferably is a silicone but can be a polyolefin such as a polyethylene or a polypropylene. Other polymers can be used but they could increase the cost of thedrinking cup assembly 10. -
FIG. 8 is a vertical cross-section of theouter cup 12 with alid 27 to fully close the outer cup. Theouter cup 12 has abase 13 and abottom wall 11. There is asidewall 12 a. Shown arehandles 14 withhandle grip ridges 17. Theouter cup threads 15 mate withthreads 29 oflid 27. In this configuration theouter cup 12 usually may contain a solid or a liquid and will provide hand grips for easy gripping by a child. However, it is very useful to contain a liquid since with thehandles 14 it can more easily be handled by a child. In contrast theinner cup 30 as shown in a vertical cross-section inFIG. 9 does not offer hand grips and can be used primarily for storing a solid product. Theinner cup 30 has asidewall 31 and abottom wall 35. Theinner cup lid 38 has aprojection 37 to fit under rolled overedge 34 ofinner cup sidewall 31. The sealinglid 38 will be continuous and will seal theinner cup 30. In this way a solid treat can be separately carried ininner cup 30 while a drink can be provided in theouter cup 12. The sealinglids outer cup 12 or theinner cup 30. These sealing lids usually will be formed from a polyethylene or a polypropylene. This can be a latching or an interference fit. -
FIGS. 10 and 11 show views of apreferred sealing gasket 46 located between the dispensingclosure 16 and theouter cup 12. It is preferred that thevalve 44 be an integral part of thegasket 46. In this embodiment thegasket 46 has thevalve 44 extending fromsupport 45 which is an integral part ofgasket 46.Gasket tab 47 provides for easier handling of the gasket/valve. This structure makes it easier to assemble thevalve 44 into the dispensingclosure 16. It also prevents the valve from being misplaced or lost. -
FIG. 12 is an elevation view of theflexible conduit straw 28 shown in a fourpart combination structure 33/39/28 b/29. It has an enlargedupper part 33 which has alower end 33 a.Connector 39 connects the enlargedupper part 33 to flexibleconduit straw mid-section 28 b. Flexibleconduit straw mid-section 28 b connects at a lower end to theweighted part 29.FIG. 13 is a plan view of the lower end 36 a of the enlargedupper portion 33. Shown in the lower end is a crosscut 33 b. This crosscut can have other shapes. The function of this crosscut is to prevent leakage from the cups when an infant or child is not sucking on the flexible conduit straw. This can be when the dispensing cup is on its side. This also is a distinct advantage during the transport of the drinking cup assembly and while it is being used by an infant or child. Although in this embodiment the crosscut is shown at a lower end of theupper end 33 a of upperenlarged part 33, the crosscut can also be located in the connector 39 (adjacent the upper or lower end), the flexibleconduit straw mid-section 28 b (adjacent either end) or in the connection of theweighted end 29 into the flexibleconduit straw mid-section 28 b. An additional flexible conduit straw modification is the deletion ofconnector 39 and a more direct connection such as enlarged upper partlower end 33 a abutting the upper end of theflexible conduit straw 28 b. A sleeve or other structure can be used to keep the parts in an abutting structure. - The
outer cup 12 will usually be a plastic and preferably a polyolefin. Suitable polyolefins are polyethylenes and polypropylenes. Polyester plastics also can be used. Suitable polyesters are the polyethylene terephthalates. Thisouter cup 12 also can be transparent or opaque. Suitable transparent plastics are polyesters and certain polypropylenes, such as clarified polypropylenes. The inner cup can be a plastic or can be metallic. If a plastic it will usually be a polyolefin or a polyester or copolyester. Useful polyesters or copolyesters are available from the Eastman Chemical Company of Kingsport, Tenn. If metallic it will be an aluminum alloy or a steel alloy, such as a stainless steel. Metals are useful since they are not prone to staining. Infant and child drinks can be a grape, cranberry or a related colored fruit. In addition metal cups are easier to clean and are unbreakable. It also is an option to use a glass, such as a Pyrex glass. The outer cup and the inner cup can be of essentially any color. This particularly is the case with the outer cup. In the space 36 between theouter cup 12 and theinner cup 30 there can be anitem 40. These items can be a person's name, a drawing, an outdoor scene, a picture, a schedule notice, an insulating material or a combination of the foregoing. The possibilities are limitless. - The
closure 16 will be comprised of a polyolefin such as a polyethylene or a polypropylene. It can be opaque, translucent or transparent. In some instances the rotatinglid 18 of theclosure 16 can be the same or a different color from that of the remainder of the closure.
