Overview & background
Disc-top and flip-top caps are designed for one-handed dispensing of pourable and squeezable products. A disc-top has a small disc you press down on one side to open the orifice; a flip-top has a hinged lid you flick up with a thumb. Both reseal positively, so the product does not leak in a bag or weep around the cap between uses.
They are the everyday closures of the bathroom and kitchen — shampoo, body wash, lotion, sauce — giving controlled, mess-free flow without the cost or priming of a pump.
