Lid For A Container
A lid assembly for a beverage container includes a lid body, a flip straw pivotally coupled to the lid body, a latch, a button, and a flexible straw coupling portion. The flip straw is rotatable between an open position and a closed position. The flexible straw coupling portion connects to the flip straw and is configured to undergo elastic deformation when the flip straw is rotated to the closed position, thereby generating a restoring force. The button includes a camming surface configured to drive the latch from a locking position to a releasing position. Upon actuation of the button, the latch releases the flip straw, and the restoring force of the flexible straw coupling portion automatically drives the flip straw to pivot to the open position, facilitating one-handed operation.
This application claims the benefit of U.S. Provisional Application No. 63/745,802, filed on Jan. 16, 2025, the entire contents of which are incorporated herein by reference.
BACKGROUNDThe present invention relates to the field of container lid, specifically to an improved lid design for insulated cups or travel mugs. Many conventional container lids are designed to be leak-proof; however, these lids often compromise ease of use, particularly when it comes to opening the drinking spout. Furthermore, most existing designs are not optimized for users who frequently use their cups in vehicles or while holding the cup with one hand.
In particular, for containers with handles that are commonly used in cars, users face the challenge of being able to easily open and access the spout for drinking without spilling or compromising the leak-proof functionality. Current lid designs either provide a secure, leak-proof seal at the cost of user convenience or sacrifice leak protection for ease of access to the drinking spout.
The present invention addresses this issue by introducing a novel structural design that places both the button to open the spout and the spout itself on the surface of the lid. This design offers a user-friendly solution, enabling convenient one-handed operation while maintaining a leak-proof seal, particularly for users who use their container in vehicles or other situations where ease of access is crucial.
SUMMARYThe disclosed invention relates to a beverage container system featuring a removable lid assembly and a convenient flip straw mechanism. The lid assembly includes a flip straw that can be opened and closed with a button, allowing a user to drink from the container easily. The lid body is securely connected to the container by a snap structure, and the flip straw is designed to pivot between open and closed positions. A vent and straw coupling portion are incorporated to facilitate fluid flow. The system uses a latch and a button mechanism, which, when pressed, disengages the latch and allows the flip straw to open for drinking. The button also ensures that the flip straw is secured when closed. The design offers an ergonomic and efficient drinking experience while maintaining a secure seal when not in use, ensuring ease of use, low complexity, and convenience in manufacturing. Various materials and configurations are possible within the described principles, allowing flexibility for different applications.

The container lid 100 may cooperate with the container body 200 to secure contents such as liquids within the container body 200. The container lid 100 may be removed entirely from the container body 200 to expose a top opening (not showing in
The container lid 100 may define a lid straw that may be relatively small, e.g. smaller than the top opening of the container body 200 and through which the interior of the container body 200 may be accessed, For example, a user may consume the contents of the container 10 through the lid straw of the container lid 100.
The lid body 170 may be connected to the upper surface 110 by a snap structure formed by snap slots 171,172 on the lid body 170 and protrusions 116,119 on the upper surface 110. The lid body 170 may also be connected to the decorative skirt 190 by a snap structure formed by snap slots 178 on the lid body 170 and protrusions 191 on the decorative skirt 190.
As shown in
The lid body 170 may further include two apertures. The first aperture 173 may be smaller than the second aperture 177. The first aperture 173 may receive a vent 111, allowing the user to more easily suck liquid from the container body 200 through the flip straw 120. The second aperture 177 may allow the straw coupling portion 160 to pass through the lid body and connect with the straw 180.
The flip straw 120 may include an opening 115. The opening 115 allows a user to consume the fluid from the container body 200. The flip straw 120 may also include a pair of engaging portions 121, which are engaged with receiving portions 171 in the lid body 170. The flip straw 120 may be pivotal, movable or rotatable between a closed position and an open position. The flip straw may further include a slot 122, which may secure the flip straw 120 in the closed position through a latch 140. The slot 122 may have a suitable depth such that the slot 122 does not communicate with the opening 115. The flip straw 120 may also include a protrusion 123, such that when the flip straw 120 is in the closed position, the protrusion 123 may be inserted into the vent 111, thereby sealing the vent 111.
The straw coupling portion 160 may include an opening 161, which may be tightly connected with the opening 124 on the flip straw 120, allowing liquid to flow through. The straw coupling portion 160 may also include two protruding portions 162 and 163 for connection. The protrusions may have any geometric shape, such as circular, directional, elliptical, or rectangular. The first protruding portion 162 may be used to connect to the connector 150, and the second protruding portion 163 may be used to connect to the lid body 170.
The straw coupling portion 160 is preferably formed of a resilient, flexible material (e.g., silicone or TPE) possessing shape memory properties. When the flip straw 120 is in the open position (as shown in
When the flip straw 120 is rotated from the open position to the closed position, the movement of the flip straw 120 exerts a compressive or bending force on the straw coupling portion 160. This action causes the straw coupling portion 160 to undergo elastic deformation, thereby storing potential energy.
Consequently, the deformed straw coupling portion 160 continuously exerts a biasing force (or restoring force) against the flip straw 120. This biasing force is configured to be sufficient to automatically drive the flip straw 120 to pivot from the closed position to the open position immediately upon release of the latch 140.
The connector 150 may include a pair of grooves 152 and a protrusion 151. The grooves 152 may engage with a pair of tongue portions 126 on the flip straw 120 by a tongue-and-groove joint. The protrusion 151 may snap into a recess 125 on the flip straw, thereby enhancing the stability of the connection between the connector and the flip straw. The connector 150 may further include an omega-shaped slot 151, which may be configured to receive the straw coupling portion, allowing it to be securely fixed to the connector 150.
As best seen in
The button 130 may include a top surface 137, which may be parallel to the upper surface of the lid when the button is in its natural state. The shape of the top surface 137 of the button may correspond to the shape of a groove 114 on the upper surface 110 of the lid, allowing the top surface 137 of the button to move downward when pressed by the user. The button 130 may further include one or more wedge-shaped protrusions 135. A hole 136 may be formed in the wedge-shaped protrusions 135 to receive one or more vertical springs 132. The button 130 may also include one or more rectangular protrusions 138, which may be connected to an abutment 176 on the lid body 170, ensuring that the button 130 maintains a horizontal orientation in its natural position without tilting.
As shown in
As best seen in
A bias member 131 may be located between the button 130 and the latch 140. The bias member 131 may have a suitable height and may be of any shape, such as spherical, rectangular, square, or cylindrical. The bias member 131 may have appropriate elasticity, allowing for a better tactile feedback when the button 130 is pressed and released.
The container lid assembly 100 may be connected to the container body 200 via threads 179. By adjusting the threads 179, the button 130 and handle 210 may be positioned in a suitable alignment. For example, as shown in
Although this invention has been described in terms of certain preferred embodiments, other embodiments apparent to those of ordinary skill the art are also within the scope of this invention. Accordingly, the scope of the invention is intended to be defined only by the claims which follow.
