Flip Top Caps: 15/415–38/400, Orifice from 2.4 to 13 mm
Flip top caps on 15/415 to 38/400 with orifices from 2.4 to 13.0 mm, sized to viscosity — sanitiser, lotion and wide mouth packs.
What we make
Range & specifications
Flip top caps from 15/415 to 38/400, with orifices from 2.4 mm to 13.0 mm, in ribbed and smooth versions, plus oval and special shapes for combination spray units. Each cap is listed with its diameter, height and orifice rather than by name alone.
Why it fits as one unit
The orifice decides the flow: 2.9 mm for a sanitiser gel, 5.0 to 6.1 mm for a lotion, 13.0 mm with a silicone valve for a wide mouth bottle. Snap-on 23 mm and 15 mm oval caps cover the tube and unit packs. Send the product viscosity and the neck, and we narrow the orifice before a sample is sent.

Patents behind the design
This line sits inside a wider portfolio of 29 valid patents (invention and utility model) across spray pumps, lotion pumps, foam pumps and aerosol cans. Where a product family carries its own design patent, it is listed on the relevant page.
Every patent number links to its Google Patents record — assignee, abstract, claims, drawings and legal status — so a buyer can confirm ownership without asking for a certificate.
