Description
This molded silicone cap can be adapted as a straw cover, lid-opening plug or removable protective closure for reusable drinkware. A pull tab can be integrated when the user needs to remove the part frequently without touching the sealing edge itself.
The source specification provides a wide customization window for dimensions and hardness, making the design suitable for projects where the cap must grip a specific opening while remaining easy to remove for drinking or cleaning.

- Material: food-grade silicone rubber.
- Round, pull-tab and custom shapes are supported.
- Hardness range: 20–80 Shore A.

What to Define Before Tooling
For a reliable quotation and mold review, the silicone part should be specified together with the mating lid or cup geometry. The most useful project inputs are:
- Opening diameter
- Insertion depth
- Pull-tab size
- Required removal force
- Color and surface finish
RFQ and Sample Review
For removable caps and plugs, specify both the installation fit and the desired pull-off force. The retention structure can then be tuned so the accessory stays in place during carrying but remains easy to clean or remove.
