DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the invention relate to lid assemblies for containers including a lid having an upper surface, a lower surface, and a projection extending downward from and around the lower surface, a seal integrally formed with and extending around the projection, and at least two flaps pivotally connected to the upper surface of the lid. The at least two flaps are movable between respective closed positions where the clasps engage an underside of a lip of the container to secure the lid assembly to the container and compress a flexible lip of the seal against the inner surface of the container, and respective open positions disengaged from the underside of the lip of the container.

With reference to the drawings, like reference numerals designate identical or corresponding parts throughout the several views. However, the inclusion of like elements in different views does not mean a given embodiment necessarily includes such elements or that all embodiments of the invention include such elements. The examples and figures are illustrative only and not meant to limit the invention, which is measured by the scope and spirit of the claims.

Turning initially to FIGS. 1-9, a lid assembly for attachment to a container, such as a glass container, is shown at reference numeral 10. The lid assembly 10 includes a lid 12, a seal 14 integrally formed with the lid 12, at least two flaps 16 pivotally connected to the lid 12, and a vent 18 attached to the lid 12. The lid may be any suitable size, such as one sized to attach to a nine by thirteen container. The lid 12 and flaps 16 may be made of any suitable material, such as polypropylene, and formed in a suitable manner, such as injection molding. The seal 14 and vent 18 may be made of any suitable material, such as thermoplastic elastomer (TPE), and formed in a suitable manner, such as injection molding. In an embodiment, the seal 14 may be overmolded onto the lid 12 and not removable from the lid.

Referring to FIG. 10 in addition to FIGS. 1-9, the lid 12 has an upper surface 30, a lower surface 32, and a projection 34 extending downward from and around the lower surface 32. The upper surface 30 includes a first area 36, a first recessed area 38, and a second recessed area 40 recessed relative to the first recessed area 38 for receiving the vent 18. Provided in the second recessed area is an indent 42 for a user's fingers that allows a user to grasp an underside of the vent 18, one or more openings 44 for receiving bosses 46 on the vent 18, and an opening 48 for receiving a protrusion 50 on the vent 18. The upper surface also has an edge 52 projecting downward and outward from the first area 36 to contact an upper surface of the container. The edge 52 includes one or more griping portions 54, such as two extending from opposite corners thereof, which extend beyond the upper surface of the container for a user to grasp to remove the lid.

The projection 34 extends downward from and entirely around the lower surface 32 to strengthen the lid, and the seal 14 is integrally formed with and extends entirely around the projection 34. As shown in FIGS. 8 and 9, a finger 60 projects downward from a bottom of the projection 34 and entirely around the projection 34 to define with the bottom of the projection 34 a ledge 62 inward of the finger 60 to assist in preventing separation of the seal from the projection. The seal 14 includes a body 64 integrally formed with the projection 34 and a radially outwardly extending flexible lip 66 projecting radially outwardly from the body 64 for sealing against an inner surface 84 of a container 80. The deflectable sealing lip 66 is shown in FIGS. 8 and 9 in a first position and shown deflected in FIG. 14 a second position.

Referring additionally to FIG. 11, the vent 18 has a substantially planar top that can be molded with indicia on it and is sized to fit within the second recessed area 40 such that a top of the vent 18 is substantially flush with the first recessed area 38. The vent 18 includes the pair of bosses 46 that are received in the openings 44 to secure the vent 18 to the second recessed area 40 of the lid and to allow the protrusion 50 to be lifted out of the opening 48 to vent air through the opening 48, such as during heating or to allow steam out of the container. The vent 18 also includes the protrusion 50 that is received in the opening 48 to also removably secure the vent 18 to the second recessed area 40. The bosses 46 and protrusion 50 also serve to seal the vent 18 to the lid 12 to minimize or prevent heat/coolness from escaping through the lid 12.

Referring additionally to FIGS. 12-14, the flaps 16 each include a plurality of pivot portions 70, and in the illustrated embodiment three pivot portions at a top of the flap 16 that removably engage with corresponding pivot portions 72 (FIG. 10) in the upper surface 30 of the lid 12. The pivot point of the flaps are provided at a top of the lid 12 to allow the flaps to lock to the container without the need for the container to have an additional locking feature to engage the flaps. The flaps each also include a radially inwardly extending clasp 74 extending along a length of the flaps 16 from an inner surface of the flap near a bottom of the flap 16. The at least two flaps 16 are movable between respective closed positions shown in FIGS. 13 and 14 where the clasps 74 engage an underside of a lip 82 of the container 80 to secure the lid assembly 10 to the container 80, and respective open positions where the clasps 74 are disengaged from the underside of the lip of the container 80.

To assembly the lid assembly 10 after the seal 14 has been formed on the lid 12, such as by molding, the flaps 16 and vent 18 are attached to the lid 12 in any suitable order. The pivot portions 70 on the flaps 16 are aligned with the corresponding pivot portions 72 on the lid 12 and pressed into the pivot portions 72 until the snap into position. The vent 18 is aligned with the second recessed area 40 and the bosses 46 inserted into the corresponding openings 44 and the protrusion 50 inserted into the opening 48 until the vent 18 is substantially flush with the first recessed area 38.

To attach the lid assembly 10 to the container 80, the flaps 16 are moved to their respective open positions and the lid positioned over the container to align a bottom of the edge 52 with the lip 82. The lid assembly 10 is then moved downward until the bottom of the edge 52 abuts the top of the lip 82. As the lid assembly 10 is moved downward, the sealing lip 66 is compressed by the inner surface 84 of the container 80 to create an airtight seal with the container 80. Once the lid assembly 10 is positioned, the flaps 16 are moved downward to their closed position where the clasps 74 engage an underside of the lip 82 to hold the lid assembly 10 to the container. The design of the lid assembly 10 allows for a seal between the lid assembly and the container despite the tolerances of the material of the container, such as with soda-lime glass.

Turning now to FIGS. 15-26, an exemplary embodiment of the lid assembly is shown at 110. The lid assembly 110 is substantially the same as the above-referenced lid assembly 10, and consequently the same reference numerals but indexed by 100 are used to denote structures corresponding to similar structures in the lid assemblies In addition, the foregoing description of the lid assembly 10 is equally applicable to the lid assembly 110 except as noted below.
