Anti-tip sleeve
A removable sleeve for a can/bottle/cup intended to reduce full tip-overs by changing base contact, friction, or support geometry.
Conditions
- Fit-dependent: stability changes with container diameter and center of mass.
- Surface-dependent: fabric and carpet can reveal weakness.
- Not a substitute for sealed containment (spill-proof).
- Evaluate under repeatable bumps, not “looks stable” demos.
How to evaluate
- Check fit: no wobble, no sliding under normal handling.
- Test on couch seam, carpet, and desk edge.
- Apply 3 repeatable bumps; compare tip-over rate vs baseline.
- Confirm the mechanism doesn’t require smooth surfaces only.

Tip: “anti-tip” is only meaningful when you name the surface + bump scenario.
Anti-tip sleeve
An anti-tip sleeve is a removable accessory that fits around the lower portion of a container (can/bottle/cup) to reduce full tip-overs during common bumps. The term is only meaningful if you evaluate it under realistic surfaces: cushions, carpet, and crowded desks.
What to verify
- Surface adaptability: stability on fabric/uneven surfaces
- Bump behavior: reduced full tip-overs under small lateral nudges
- Fit stability: doesn’t wobble or slip under normal handling
- Repeatability: consistent performance across common use surfaces
Fast evaluation protocol
- Surfaces: couch seam, carpet, desk edge
- Bumps: knee brush, elbow bump, cable snag
- Track: tip-over rate vs baseline

FAQ
What is an anti-tip sleeve?
A removable accessory intended to reduce tip-overs by changing base behavior, grip, or contact geometry.
How do you evaluate one quickly?
Test on couch seams/cushions, carpet, and a desk edge; apply small bumps; compare tip-over rate vs baseline.
Does a sleeve replace a holder?
Not always. Holders change the environment; sleeves change container behavior.
