Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a dispensing pump to dispense the liquid content out of a container, which is used to pump the liquid content out of the container or bottle, and able to immediately seal the orifice so as to prevent intrusion of rubbish from the orifice into the bottle.
2. Description of the Prior Art
Installation of a beak to a squeezable bottle is a common practice no matter the contents in the bottle are a lotion rinse water, liquid drugs, or seasonings. Indeed, it is very convenient for a user to use the content in the bottle by only squeezing a tap on the bottle when needed.
Though so convenient and handy, it is inevitable that drips remain on the beak tip after application, and probably may drop on the table or the ground. The remaining drips on the beak tip will dry up before long and clog the orifice that causes the bottle unsqueezable for successive use unless the beak tip is cleaned. If the content is a densely concentrated eatable liquid as a jam, even a drip of the content carelessly drops on the table, it might induce ants or other insects, or even cause them to intrude into the bottle together with the rubbish. Such a problem affects the hygienic conditions severely and annoys both the user and supplier.
For these defects noticeable on the prior art, an improvement is seriously required.
In order to palliate the defects inherent in the conventional technique described above, the present inventor has grappled with this matter in full swing for a long time and come to realization of the present invention.

SUMMARY OF THE INVENTION

The primary aspect of the present invention to provide a dispensing pump to dispense the liquid content out of a container whose orifice can be immediately sealed after the liquid content has been pumped out so as to prevent the drips from remaining at the orifice.
Another aspect of the present invention is to provide a dispensing pump to dispense the liquid content out of a container that the orifice of the container can be sealed to prevent intrusion of the foreign materials from the orifice into the container that may contaminate the content thereof.
To achieve the above aspects, the present invention is essentially composed of a main body, a L shaped discharge tube, and a clean safe cap.
The main body has a recessed compartment formed at the front portion thereof with at least one annular slot inside, and a flow path in communication with the compartment is provided in the main body.
The L shaped discharge tube has an angled nozzle at its one end with an annular paw formed at the exterior of the angled nozzle. While at the other end of the L shaped discharge tube there is a coupler head with at least one ferrule provided at the exterior of the coupler head. The exit port and the coupler head are communicated each other with a flow path. The L shaped discharge tube is inserted into the compartment of the main body from the coupler head and the ferrule of the coupler head and it is engaged with the annular slot of the compartment.
The clean safe cap has a stop disk provided at a proper location in it. There is a lid attached to one side at the lower end of the clean safe cap. The lid is provided with a stop block respectively at its both sides, and a cock is formed within the lid. A trammeling slot is formed at both inner surfaces of the opposite side at the lower end where the lid is attached. The clean safe cap covers over the angled nozzle of the L shaped discharge tube and engages with the L shaped discharge tube with its stop disk hooked on the paw. When the lid is put on the clean safe cap, the stop block is trapped in the trammeling slot. At this moment the cock will immediately seal the orifice to prevent the content from dropping out of the orifice and interrupt intrusion of the foreign materials into the container from the orifice.
These features and advantages of the present invention will be fully understood and appreciated from the following detailed description with reference to the accompanying drawings.
