Abstract This invention presents to the art a novel, improved plastic nozzle cap for a compressible tube having a sealed outlet opening. The novel, improved nozzle cap comprises an outlet bore and means for securing the cap to the tube. The outlet bore is positioned in a predetermined relationship with the outlet opening of the tube to which the cap is to be secured so that when the cap is secured to the tube, a device can be inserted into the outlet bore to pierce the sealed outlet opening of the tube. The device used to pierce the sealed outlet is an integral part of the cap but can be readily broken from the cap. The broken off device has a portion dimensioned and shaped so that the device has the capability for piercing the sealed outlet opening of the tube and for closing the outlet bore.
A plastic nozzle cap for a compressible tube having a sealed outlet opening, said cap comprising an outlet bore, means for securing the cap to the tube, said outlet bore being positioned in a predetermined relationship with the outlet opening of the tube to which it is to be secured so that when the cap is secured to the tube, a device can be inserted into the outlet bore to pierce the sealed outlet opening of the tube said device being joined with a peripheral surface of the cap by means of an integrally molded frangible rib so that it can be readily broken from the cap and having a portion dimensioned and shaped so that the device can be inserted into the outlet bore for piercing the sealed outlet opening of the tube and for closing the outlet bore.
