Product Overview

A silicone cup lid cover sits over a matching cup opening to provide a removable top. ETOL offers custom size and color options, allowing the rim relationship to be developed for the particular vessel. The lid should be evaluated on that cup rather than assumed to fit every container with a similar nominal diameter.

Compare the cup's outer rim, any rolled edge and the space immediately below it. These details determine where the flexible cover engages and whether it sits level. The removal area should be accessible without pulling the lid across the contents. A lid that appears secure while resting on a bench may behave differently when the cup is handled.

For direct contact with food or drink, use a silicone formulation suitable for the intended contents and cleaning conditions. Choose the food-contact formulation for the particular cup application and evaluate the lid with its intended contents. Assess any spill resistance or heated-use requirement with the complete vessel and fitted cover.

Clean the lid's contact region and inspect it for trapped residue before fitting. Allow it to settle naturally around the rim instead of stretching one side excessively. Replace a torn or permanently distorted cover, and assess any required transport use with the complete cup-and-lid combination.

Material options: Custom silicone compound; formulation and geometry developed together.
Hardness selection: Silicone options: 20–80 Shore A. The removal area should be accessible without pulling the lid across the contents.
Custom geometry: ETOL offers custom size and color options, allowing the rim relationship to be developed for the particular vessel.
Fit evaluation: Choose the food-contact formulation for the particular cup application and evaluate the lid with its intended contents.
Color & OEM: Custom colors; OEM identification positioned outside closure contact surfaces.

Ordering this custom component

Can the shape be adjusted to my mating parts?

Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.

Which details should be agreed before tooling?

Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.

Can a sample help define the replacement?

A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.

How is the quotation for this part determined?

The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
