The present disclosure herein relates broadly to lids for drinkware, and more specifically to leak resistant lids for drinkware containers that provide a means for drinking.
Beverage containers can be filled with hot or cold drinkable liquids, such as water, coffee, tea, soft drink, or alcoholic beverage, such as beer. These beverage containers can be made of a variety of materials such as stainless steel, glass, plastic, cardboard, or paper material. Lids may be provided on beverage containers to provide a means for drinking the contents of the beverage container while also being resistant to leaks if spilled.
This Summary provides an introduction to some general concepts relating to this disclosure in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the disclosure.
Aspects of the disclosure herein may relate to a lid assembly for a beverage container, where the lid assembly comprises: a base including: (a) a cover member; (b) a lip extending upward from the cover member; the lip positioned around a perimeter of the cover member; (c) a skirt member extending downward from the cover member; (d) a retaining wall spaced inward from the skirt member creating a grommet groove between the skirt member and the retaining wall; (e) a primary opening in the cover member; and (f) a secondary opening spaced from the primary opening. The lid assembly further including a straw extending through the primary opening; and a grommet arranged in the grommet groove. The grommet may include a primary body member and a spiral ring extending outward from an outer surface of the primary body member, where the spiral ring creates an airflow path from below the lid assembly to the secondary opening. The spiral ring may contact an inboard surface of the skirt member, where an outboard edge of the spiral ring compresses against the inboard surface of the skirt member. The primary opening may be larger than the secondary opening. The lid assembly may also include a gasket arranged in a gasket groove in the skirt member, where the gasket includes a body member and an annular ring extending outward from an outer surface of the body member, and where the annular ring contacts an inner surface of the beverage container.

A first gap on a first annular ring is located at a different location on a first perimeter of the first annular ring than a second gap located on a second perimeter of a second annular ring. The grommet may include a secondary body member extending inward from the primary body member and a straw opening in the secondary body member, where the straw extends through the straw opening. The lid assembly may also include a gasket arranged in a gasket groove in the skirt member, where the gasket includes a body member and an annular ring extending outward from an outer surface of the body member.
The foregoing Summary, as well as the following Detailed Description, will be better understood when considered in conjunction with the accompanying drawings in which like reference numerals refer to the same or similar elements in all of the various views in which that reference number appears.
In the following description of the various examples and components of this disclosure, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration various example structures and environments in which aspects of the disclosure may be practiced. It is to be understood that other structures and environments may be utilized and that structural and functional modifications may be made from the specifically described structures and methods without departing from the scope of the present disclosure.
Also, while the terms “front,” “top,” “base,” “bottom,” “side,” and “rear” and the like may be used in this specification to describe various example features and elements, these terms are used herein as a matter of convenience, e.g., based on the example orientations shown in the figures and/or the orientations in typical use. Additionally, the term “plurality,” as used herein, indicates any number greater than one, either disjunctively or conjunctively, as necessary, up to an infinite number. Nothing in this specification should be construed as requiring a specific three dimensional or spatial orientation of structures in order to fall within the scope of the claims.
In general, this disclosure may relate to a leak resistant lid assembly with a straw or similar means where a user can drink liquid from a lid with an opening in the top. When drinking from a straw, air must travel into the container to prevent a vacuum from occurring. This requires a secondary opening in the lid that is separate from the straw or straw opening. In addition, when installing a press fit-type lid assembly, air must be able to escape to prevent the liquid in the container from traveling up the straw, which could cause a spill or leak. A secondary opening in the lid may help to address a vacuum from forming or liquid from traveling up the straw, but this secondary opening provides an additional leak path that needs to be addressed.
As shown in
To form a seal between the base 110 and the container 10, gasket 160 may be arranged in a gasket groove 122 in the skirt member 120, where the gasket 160 includes a body member 162 and an annular ring 164 extending outward from an outer surface 166 of the body member 162. Annular ring 164 may be a projection that extends outward from the body member 162 around the perimeter of the body member 162 at same vertical location of the gasket 160. The gasket groove 122 may be located below a shelf 128 of the base 110 formed opposite a top surface of the lip 114 adjacent the outboard surface 124 of the skirt member 120. An outer edge 168 of the annular ring 164 may contact and compress against an inner surface of the container 10 to create an effective seal to prevent both liquid and air from escaping between the container 10 and the lid assembly 100 where the gasket 160 contacts the container 10. As shown in the illustrated examples, the gasket 160 may include a plurality of annular rings 164 to ensure no liquid or air escapes from this seal. Alternatively, the gasket 160 may not have annular rings and may only have a compressible main body member 162, such as an o-ring.
The grommet 170 may include a main body member 172, which may also be referred to as a primary body member, with a spiral ring 174 extending outward from an outer surface 176 of the main body member 172. The main body member 172 may be received in the grommet groove 138 of the base 110, where the grommet 170 is installed from the bottom 104 of the lid assembly 100 as shown in
The spiral ring 174 of the grommet 170 may comprise a tapered cross section and may extend around a portion of the outer surface 176. The spiral ring 174 may have a first end 184 on a lower portion of the main body member 172 and gradually moves upward along the main body member 172 as the spiral ring 174 moves around the main body member 172. The spiral ring 174 may be a continuous member that extends at least 180 degrees around the primary body member 172, or in other words, the spiral ring 174 makes at least one half of a revolution around the primary body member 172. In some examples, the spiral ring 174 may be a continuous member that extends at least 360 degrees around the primary body member 172, or in other words, the spiral ring 174 makes at least one revolution around the primary body member 172. In other examples, the spiral ring may extend at least 540 degrees around the primary body member 172, at least 720 degrees around the primary body member 172, or at least 900 degrees around the primary body member 172. An outboard edge 180 of the spiral ring 174 may contact and compress against an inboard surface 125 of the skirt member 120 creating a seal between the spiral ring 174 and an inboard surface 125 to form a spiraled flow path 182 in the lid assembly 100 as shown in
The grommet 170 may also help form a seal between the primary opening 116 and the straw 150. The grommet 170 may include a secondary body member 186 extending inward from the main body member 172 and a straw opening 188 in the secondary body member 186. The secondary body member 186 may be releasably secured within the primary opening 116, where the straw opening 188 is substantially aligned with the primary opening 116. The straw 150 may extend through the straw opening 188 where the secondary body member 186 compresses to form a seal between the straw 150 and the grommet 170 to prevent any liquid from leaking from the container 10 between the straw 150 and the grommet 170. The grommet 170 may also include a connecting member 190 that extends from the main body member 172 to the secondary body member 186. The connecting member 190 may extend around a lower end 132 of the retaining wall 130. As shown in the illustrated example, the grommet 170 may be a unitary member that includes both the main body member 172 and the secondary body member 186. Alternatively, the grommet 170 may be formed as separate members where a primary grommet provides the spiraled flow path 182 and a secondary grommet fits within the primary opening 116 to provide a seal between the straw 150 and the cover member 112. As another feature, the grommet 170 may include a pull-tab 192 that allows a user to easily grasp and remove the grommet 170 from the lid assembly 100 for periodic cleaning.
Referring back to
The base 110 of the lid assembly 100 may include features to assist in attachment to the container 10. For examples, lid assembly 100 may include external threads 126 arranged on an outboard surface 124 of the skirt member 120 to engage internal threads arranged on an interior surface of the container 10. The lip 114 may include ridges 115 arranged on opposite sides of the lip 114 to allow a user to easily grip and turn the lid assembly 100 to engage allow the external threads 126 to engage internal threads of the container 10. The shelf 128 may act as a stop for the lid assembly 100 when the shelf 128 contacts an upper surface of the container 10 when the lid assembly 100 is attached to the container 10.
The base 110, straw 150, gasket 160, and grommet 170 may each be formed using a molding process, such as injection molding. In some examples, the straw 150 may be extruded, where the stop 152 may be formed by overmolding it onto the extruded portion using injection molding. In addition, in some examples, the gasket 160 and grommet 170 may be compression molded. The base 110 and straw 150 may be molded from a clear or transparent polymer material, such as Tritan™ or other food safe polymer. In some examples, the retaining wall 130 may be formed of an opaque food-safe polymer material using a two-shot molding process. The two-shot molding process may help to improve aesthetics of the base 110 by providing different color options and to mask the appearance of the grommet 170. As another option, the gasket 160 and/or the grommet 170 may be overmolded onto the base 110. The gasket 160 and grommet 170 may be formed from a compressible elastomeric material, such as a silicone-based material, neoprene, nitrile, EPDM, or a rubber-based material. However, additional or alternative polymeric materials may be used, without departing from the scope of this disclosure.
As shown in
To facilitate a press fit engagement between the lid assembly 200 and the container 20, the base 210 of the lid assembly 200 may include features to assist in attachment to the container 20. For example, skirt member 220 may include a tapered end member 221 to help guide the base 210 into the container 20. In addition, the lip 214 may include a lid tab 227 that extends outward at the rear 208 of the lid assembly 200 to provide a user a location to easily grasp and remove or install the lid assembly 200. The shelf 228 may act as a stop for the lid assembly 200 when the shelf 228 contacts an upper surface of the container 20 when the lid assembly 200 is attached to the container 20.
Similar to lid assembly 100, the gasket 260, which may be similar to gasket 160, may help form a seal between the lid assembly 200 and the container 20 to prevent any liquid from leaking from the container 20. In addition, the contact between the annular rings 264 and interior of the container 20 may help to secure the lid assembly 200 to the container 20. In the illustrated example, the gasket 260 may be located in the gasket groove 222 where the gasket groove 222 is spaced away from the shelf 228. The gasket groove 222 may be located below a shelf 228 of the base 210 formed opposite a top surface of the lip 214 adjacent the outboard surface 224 of the skirt member 220.
The grommet 270 may be similar to grommet 170 of lid assembly 100. The grommet 270 may include a main body member 272, which may also be referred to as a primary body member, with a spiral ring 274 extending outward from an outer surface 276 of the main body member 272. The main body member 272 may be received in the grommet groove 238 of the base 210. An outboard edge 280 of the spiral ring 274 may contact and compress against an inboard surface 225 of the skirt member 220 creating a seal between the spiral ring 274 and an inboard surface 225 to form a spiraled flow path in the lid assembly 200. The grommet 270 may include a secondary body member 286 extending inward from the main body member 272, and a straw opening 288 in the secondary body member 286. The straw 250 may extend through the straw opening 288 where the secondary body member 286 compresses to form a seal between the straw 250 and the grommet 270 to prevent any liquid from leaking from the container 20 between the straw 250 and the grommet 270.
The gasket 360 may provide an airflow path from an interior of the container to the exterior environment, while also resisting liquid from inside the container from leaking from the container. Gasket 360 may be arranged in a gasket groove 322 in the skirt member 320. As shown best in
The grommet 380 may seal between the opening 316 and the straw 350. The grommet 380 may include a body member with a straw opening. The straw may extend through the straw opening where the body member compresses to form a seal between the straw 350 and the grommet 380 to prevent any liquid from leaking from the container between the straw and the grommet 380.
Referring back to
The base 310 of the lid assembly 300 may include features to assist in attachment to the container. The illustrated example of lid assembly 300 in
Similar to the examples for lid assemblies 100 and 200, the base 310, straw 350, gasket 360, and grommet 380 may each be formed using a molding process, such as injection molding. The base 310 and straw may be molded from a clear or transparent polymer material, such as Tritan™ or other food safe polymer. The gasket 360 and grommet may be formed from a compressible elastomeric material, such as a silicone-based material. However, additional or alternative polymeric materials may be used, without departing from the scope of this disclosure.
