Abstract
A spill-proof training cup includes a lid with a passage housing a valve. The valve has a valve plane parallel to or forming a selected angle with the passage. The valve plane has a port and a stopping flap attached outside the port to block the port and stop liquid from flowing out. When the cup is sucked on, a pressure difference is generated to overcome the blocking force of the stopping flap and a gap is generated between the stopping flap and the port so that the liquid contained in the cup body may pass through the port. The port and the passage form an angle so that when the training cup is inverted, the liquid contained in the cup does not directly hit the stopping flap and the barrier plane of the valve can block the liquid so that the liquid does not flow out improperly.
Description
- The invention relates to a spill-proof training cup that has a valve with a valve plane parallel to or forming an angle with the passage (or a port on the valve plane blocked by a barrier plane) so that when the training cup is inverted, liquid contained in the cup does not directly hit the valve plane or port and does not flow out improperly.
- The milk bottle is an indispensable item used by babies every day. It is used to contain milk or water for a baby to consume by sucking. The milk bottle usually has a teat on the front end for the baby to suck. The teat generally is made from a pliable plastic such as silicon rubber and has a vent formed in a cross slit to prevent spillage in the event that the milk bottle is toppled. When the baby grows up and becomes a young child, a
training cup 10 such as the one shown inFIG. 1 is generally used to enable the child to practice drinking. Theconventional training cup 10 generally includes alid 11 to close acup body 12, and aspout 13 integrally formed on thelid 11. Thespout 13 has avent 14 to dispense milk or water for the child to drink. - The conventional training cup aims to enable young children to practice drinking before using a regular cup. However, the conventional training cup still tends to spill liquid through the vent when inverted, which is troublesome. There are designs to remedy this problem, such as U.S. Pat. Nos. 5,890,621, 6,321,931, and 5,186,347. They mainly have a valve to block the liquid from flowing out improperly when not being sucked on by the child. They have a common feature of providing a means parallel to the liquid contained in the training cup and a valve diaphragm (generally a pliable plastic) with a slit to control the liquid from flowing out improperly. As the valve diaphragm is parallel to the liquid, when the cup is inverted, the liquid hits the valve diaphragm directly, and the slit in the center of the valve diaphragm can be opened and result in improper spilling of the liquid.
- The primary object of the invention is therefore to provide a novel spill-proof training cup to prevent liquid from flowing out through the valve improperly. The invention mainly has a valve located in a passage of a lid. The valve has a valve plane forming an angle with the passage. The valve plane has a port blocked by a stopping flap on the outer side to prevent the liquid from flowing out. When a child sucks the spout, a pressure difference is generated to overcome the blocking force of the stopping flap so that a gap is formed between the stopping flap and the valve to allow the liquid contained in the cup to flow out through the port. As the port and the passage form an angle, when the training cup is inverted and the liquid in the cup flows to the passage, the liquid does not directly hit the stopping flap but is blocked by the barrier plane of the valve, hence the liquid in the cup does not flow out improperly.
- The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings. The descriptions and drawings are for illustrative purposes only, and are not limitative of the invention.

FIGS. 2 through 5 , the spill-proof training cup 2 of the invention mainly aims for young children to practice drinking and to prevent liquid from spilling improperly when inverted. The spill-proof training cup 2 includes acup body 3, alid 4, avalve 5, and a stoppingflap 6. - The
cup body 3 has ahousing compartment 31 for holding the liquid and anopening 32. The perimeter of theopening 32 has afastening section 33 to couple with alid 4. In this embodiment, thefastening section 33 is a screw thread. The opening 32 also may have a flange (not shown in the drawings) on the outer periphery to couple with thelid 4. Thelid 4 mainly aims to cover theopening 32 and confine the liquid in thehousing compartment 31. The lid further has asuction spout 41 extended upwards for a child to suck with his or her mouth. Beneath thesuction spout 41, there is apassage 42 to allow the liquid contained in thehousing compartment 31 to flow out through thesuction spout 41. Thelid 4 also has anair vent 43 to allow the air in thecup body 3 to communicate with the external atmosphere. - The
valve 5 is located in thepassage 42 of thelid 4 to block the liquid from flowing through. It has a cross section substantially formed in a Z-shape and includes anupper barrier plane 51 and alower barrier plane 52 that can stop the liquid from flowing to thepassage 42 and withstand the impact of the liquid when thetraining cup 2 is inverted. The impact is generated because the horizontal surface 50 of the liquid is spaced from thepassage 42 at a distance. In addition, thevalve 5 has avalve plane 53 parallel to or forming a selected angle with thepassage 42. The valve plane divides the passage into abarrier section 54 and a flowingsection 55 so that the liquid does not directly hit thevalve plane 53. Thevalve plane 53 has aport 56 to allow the liquid to pass through. In this embodiment, thevalve 5 may be formed in various styles, such as a L-shape (referring toFIGS. 6 and 7 ). The main consideration is to prevent the liquid from directly hitting theport 56 or thestopping flap 6 while thetraining cup 2 is inverted and to reduce the impact of the liquid to prevent spillage. - the
stopping flap 6 is partially connected to one side of thevalve 5 where theport 56 is formed. In this embodiment, the stoppingflap 6 is made from a pliable plastic such as silicon rubber. The stoppingflap 6 is resilient enough to close theport 56. Thus when thecup body 3 is accidentally toppled, the liquid contained inside does not flow out through theport 56 freely. However, when a child sucks thesuction spout 41, the suction force overcomes the blocking resilience of thestopping flap 6 and a gap is generated between thestopping flap 6 and theport 56 to allow the liquid in thecup body 3 to flow out through the passage to be consumed by the child. - Referring to
FIGS. 8 and 9 , the spill-proof training cup 2 of the invention mainly aims for young children to practice drinking and to prevent liquid from spilling improperly when inverted. The main feature of the invention is to provide avalve plane 72 of avalve 7 to form a selected angle with a passage to buffer the impact of the flowing liquid. Thevalve 7 is located in the passage of thelid 4 to prevent the liquid from passing through. Thevalve 7 has abarrier plane 71 and avalve plane 72. Thebarrier plane 71, aside from blocking the liquid from flowing to thepassage 42, can also withstand the impact of the liquid when thetraining cup 2 is inverted. The impact is generated because the horizontal surface of the liquid is spaced from the passage at a distance. Thevalve plane 72 is made from a pliable material (such as silicon rubber) and is parallel to or forms a selected angle with thepassage 42 to divide thepassage 42 into abarrier section 54 and a flowingsection 55 so that the liquid does not directly hit thevalve plane 72. Thevalve plane 72 has a throughslit 73 so that when the cup body is accidentally toppled, the liquid contained inside does not flow out through theslit 73 freely. However, when a child sucks thesuction spout 41, the suction force generates a gap on theslit 73 to allow the liquid in thecup body 3 to flow out through theslit 73 and thepassage 42 to be consumed by the child. - Referring to
FIGS. 10, 11 and 12, the spill-proof training cup 2 of the invention mainly aims for young children to practice drinking and to prevent liquid from spilling improperly when inverted. The main feature of the invention is to provide a barrier plane on a valve to buffer the impact of the flowing liquid. It includes avalve 8 located in the passage of thelid 4 to prevent the liquid from passing through. Thevalve 8 has anupper barrier plane 81 and alower barrier plane 82. There is aport 83 corresponding to thelower barrier plane 82. Theport 83 is covered by a stoppingflap 9, which is attached by latching or bonding a portion thereof. The stoppingflap 9 closes theport 83 when there is normal pressure to block the fluid from flowing improperly into thepassage 42. As the horizontal surface of the liquid is spaced from thepassage 42 at a distance, when the training cup is inverted, an impact is generated when the liquid flows to thepassage 42. Theupper barrier plane 81 and thelower barrier plane 82 withstand the impact so that the liquid does not directly hit the stoppingflap 9 on theport 83. Thus the liquid is prevented from flowing out freely. However, when a child sucks thesuction spout 41 of thelid 4, a pressure difference is generated to bend and deform one side of the stoppingflap 9 and form agap 80 between the stoppingflap 9 and thevalve 8 to allow the liquid to flow out and to allow the liquid to be consumed by the child. - While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
