The CapTool system
One bottle. Three jobs.
Rinse, drip, and pour caps that all fit the same common beverage bottles. Buy one. Come back for the others.
Phase 1
CapTool Rinse
Sandy feet, muddy paws, sticky hands. Snap on, squeeze, rinse.
Phase 2
CapTool Drip
Slow-release watering for houseplants, patios, and seedlings.
Phase 3
CapTool Pour
Controlled pour for camp water, garden feed, and emergency kits.
The Kit
Utility Kit
Rinse, Drip, and Pour in a small carry pouch with compatibility card.
How it works
Three steps. No new bottle required.
Snap on
The flexible silicone cap fits many common 28mm beverage bottles. Press it on, twist a quarter turn.
Squeeze
Use the bottle you already have. Squeeze for the spray, or invert and let gravity do the work.
Rinse, drip, or pour
Clean sandy feet, water plants for the weekend, or pour without spilling.
Where it earns its place
The car, the bag, the campsite.
Six places CapTool gets used the most.
Beach
Sand off, before the car.
Rinse feet, gear, and dogs at the boardwalk so the back seat stays clean.
Pets
Muddy paws, handled.
One squeeze rinses paws after the trail before they hit the upholstery.
Camp
Camp dishes without a sink.
Quick rinse for dishes, hands, and gear when running water is two miles away.
Garden
Watering while you’re away.
The Drip cap turns a 1L bottle into slow-release plant care for the weekend.
Sports
Sticky hands at halftime.
Sideline rinse for orange wedges, cleat mud, and post-game cleanup.
Emergency
Hygiene when there’s no tap.
Three caps in a kit pouch. Hand rinse, water transfer, basic cleanup.
Honest fit
Fits many common plastic beverage bottles.
We tested CapTool Rinse against the most common 28mm beverage bottles in the US. The full list is published and updated as new bottles get tested.
We don’t claim “universal.” The cap is built around the 28mm finish family with a flexible gasket that extends fit to nearby sizes. Test before regular use.
Common questions
Quick answers.
What bottles does CapTool Rinse fit?
CapTool Rinse fits many common 28mm plastic beverage bottles, including most 16.9oz waters, 1-liter waters like Smartwater and Fiji, 2-liter sodas, and many sports drinks. The full tested list lives on our compatibility page. We don’t claim “universal” because bottle finishes vary by brand.
Is it safe to drink water that touches the cap?
The cap is made from food-contact-grade silicone, BPA-free, and meets FDA 21 CFR food contact requirements. The cap is designed for rinsing, not for drinking through. The bottle itself is the drinking surface.
How is this different from a bottle shower cap on Amazon?
Most bottle shower caps are single-SKU products with generic packaging and no compatibility list. CapTool is built as a system: Rinse, Drip, Pour, and a Kit, with a published compatibility list, demonstration videos for each use case, and a brand that retailers can stock with confidence.
Can I use it for hot liquids, fuel, or cleaning chemicals?
No. CapTool is designed for water and standard beverage liquids only. Not for hot liquids, fuel, bleach, pesticides, hazardous chemicals, or pressurized contents. Full safety guidance ships with every package.
What’s your return policy?
30 days from delivery for any reason. Unused product in original packaging gets a full refund. Defects and damage covered with a prepaid return label and replacement. Full details on our returns page.
Do you sell wholesale to retailers?
Yes. Beach stores, pet retailers, garden centers, camping shops, and emergency-prep distributors can request our wholesale packet with MOQs, lead times, and the full pitch deck.
For buyers and distributors
Built for shelf, kit, and gift.
CapTool fits beach, pet, garden, camping, and emergency-prep aisles with one product family. Strong sell-through proposition, retail-ready packaging, full demo video library for in-store and online use.
