Abstract
A rigid dip tube connector for a trigger spray bottle having a threaded opening. A cap body is screwed onto the opening and has a hinged cap attached thereto. The cap body has an annulus and an opening in the center for supporting a rigid dip tube. A plastic connector is provided and has a cylindrical bore extending from its bottom which fits into the opening in the cap body. The plastic connector is cylindrical and has an annulus in its upper portion for receiving a flexible tube for connection to a sprayer. The plastic connector fits into the annulus of the cap body so that the rigid dip tube and flexible tube align with one another. In a second embodiment, the annulus of the cap body is open and the rigid dip tube connects directly to the plastic connector or plunger. As a result, the plastic connector by itself connects and aligns the rigid dip tube and the flexible tube. The plastic connector snap fits into the opening of the cap body.
