TECHNICAL FIELDThe present disclosure relates generally to a closure for a fluid containing vessel. More specifically the present disclosure relates to a multi-piece closure for a fluid containing vessel that may be attached to the fluid containing vessel without regard to the orientation of the fluid containing vessel.
BACKGROUND OF THE INVENTIONMany fluid containing vessels, such as drink bottles and motor oil bottles, are provided with a spout or a nozzle that allows fluid within the bottle to be accessed by a user. The spout or nozzle is often covered by a closure with a lid or a flip-top lid. A user can access the contents of the container by moving the hinged lid from a closed position to an open position. A user can also provide a fluid tight seal for the container by moving the hinged lid back to the closed position. Such an application is particularly useful in certain beverage containing vessels, such as bottles for water, juices, sports drinks, or beverages for children, where a user may periodically desire access to the contents of the vessel, but also wishes to avoid spilling the contents of the vessel once the contents have been accessed.
Existing multi-piece closures often utilize a non-position memory strap to connect a cover portion of the lid to a ring portion of the lid. Additionally, the strap is connected to an exterior surface of a ring portion of the lid, and portions of the strap reside outside of a periphery formed by the ring portion. Therefore, when the lid is connected to the rest of the closure, i.e., by pushing the ring portion into a base, a particular orientation of the strap must be maintained relative to the assembly equipment which pushes the ring into the base to avoid potentially damaging the strap or having the strap interfere with operation of assembly equipment. This requires more complex assembly tooling that may increase the amount of time required to produce a completed closure and may further increase the cost to produce a closure. Additionally, manufacturing a strap which is connected to the exterior surface of the ring portion is difficult and may require a slidable mold piece on a separate axis in order to remove the lid piece from the mold. Therefore, a need exists for a closure with a lid that does not require circumferential orientation with respect to the to the assembly equipment during assembly, does not require a slidable mold piece, and can maintain access to the spout or nozzle with position memory when the hinge is in the open position.
Furthermore, as the existing hinged closure can be closed to form a fluid tight seal in the closed position even after being initially opened, it is often desirable to provide an optional tamper evident feature so that a user may determine if the closure has previously been opened. Many tamper evident features are disposed in a generally vertical direction between portions of the closure with a hinged lid, such that the tamper evident features deform or even break when a hinged lid is initially opened. Manufacturing a closure with such vertical features may also require slidable mold pieces or a costly secondary operation to the molding (i.e., slitting).
The present invention seeks to overcome certain of these limitations and other drawbacks of the prior art, and to provide new features not heretofore available. A full discussion of the features and advantages of the present invention is deferred to the following detailed description, which proceeds with reference to the accompanying drawings.
SUMMARY OF THE INVENTIONAccording to one embodiment, a closure for a fluid containing vessel comprises a base and a one-piece lid. The base has a sidewall and a shoulder formed at a top surface of the sidewall. A spout extends upward from the shoulder and has an opening formed in a top surface of the spout. The one-piece lid has a ring portion, a hinge portion and a cover portion. The hinge portion connects the cover portion to the ring portion and allows the cover portion to move from a closed position to an open position. The hinge portion is disposed completely within an outer periphery of the ring portion with the cover portion in the closed position. The cover portion covers the opening in the top surface of the spout in the closed position to form a fluid tight seal between the base and the one-piece lid.
According to another embodiment, a closure for a fluid containing vessel comprises a base portion and a lid portion. The base portion comprises a generally horizontal shoulder portion, a first generally vertical sidewall, a second generally vertical sidewall, and a securing groove. The generally horizontal shoulder portion has an outer periphery and an inner periphery. The first generally vertical sidewall extends in a first direction from the outer periphery of the shoulder portion. The second generally vertical sidewall extends in a second direction from the inner periphery of the shoulder portion. The second generally vertical sidewall terminates in a generally horizontal rim. The generally horizontal rim has an opening formed therein. The securing groove is disposed radially between the first generally vertical sidewall and the second generally vertical sidewall. The lid has a connecting ring having a periphery with a complimentary shape to the securing groove of the base portion and forms a friction fit within the securing groove. The cover portion has a hinged connection to the connecting ring. The cover portion is movable between a closed position and an open position. The hinged connection is disposed within the periphery of the connecting ring when the cover portion is in the closed position. The cover portion is disposed over the opening of the horizontal rim of the base portion. The connecting, ring, cover portion, and the at least one tamper evident feature form a single piece.
According to a further embodiment, a lid for a fluid containing vessel comprises a connecting ring, a cover portion, and a hinge. The connecting ring has a periphery with a generally circular shape. The cover portion is connected to the connecting ring by a hinge. The cover portion is movable between a closed position and an open position. The hinge forms between the connecting ring and the cover portion. The hinge is disposed within the periphery of the connecting ring when the cover portion is in the closed position.
Other features and advantages will be apparent from the following specification taken in conjunction with the following drawings.
To understand the present invention, it will now be described by way of example, with reference to the accompanying drawings in which
While this invention is susceptible of embodiments in many different forms, there are shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
The lid portion 14 comprises a connecting ring 24 and a cover portion 26 which are connected via a hinge 28. The connecting ring 24 is depicted as forming a complete circle in the embodiment of
The lid portion 14 is moveable from a closed position, as shown in
As best viewed in
The cover portion 26 of the lid portion 14 additionally has an opening tab 30. The opening tab 30 is disposed on an opposite side of the lid portion 14 from the hinge 28. It is contemplated that the opening tab 30 may be positioned elsewhere on the lid portion 14. The opening tab 30 allows a user to more easily move the lid portion 14 from the closed position to the open position.
The hinge 28 is completely disposed within the diameter or perimeter of an outer periphery of the connecting ring 24 when the lid portion 14 is in the closed position. Therefore, all of the lid portion 14 is disposed within the outer periphery of the connecting ring 24, whether at, below or above the ring's surface. When the hinge is attached at or below the ring's surface, the orientation of the lid portion 14 relative to the base portion 12 does not need to be controlled when attaching lid portion 14 to the base portion 12 via the connecting ring 24 being inserted into the securing groove 32, simplifying the assembly of the lid portion 14 to the base portion 12.
The hinge 28 is disposed at or above the level of the shoulder portion 18 of the base portion 12. The higher the hinge 28 resides above the shoulder portion 18, the greater the opening angle of the hinge 28.
