Description

Technical Field

[0001] The utility model relates to the field of spray capping for sprays, in particular to a push button device for producing a spray cap. Background Art

[0002] Unlike ordinary bottle packaging screw caps, the screw capping method of spray bottles is relatively complicated. There is a nozzle on the top of the spray cap and an irregular hose below. Compared with the hard tube, the hose is longer, and the end of the tube can be extended to the bottom end of the tank when curled, making the drug use cleaner. However, the hose has an irregular shape, and it is difficult to align the hose using ordinary cap feeding equipment. Therefore, we currently use the method of workers putting the cap body into the screw cap, which makes the packaging screw capping efficiency low. Therefore, we designed a spray production cap push button device. Utility Model Content
