DETAILED DESCRIPTION

(5) The technical solutions in the embodiments of the present invention will now be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. It will be apparent that the described embodiments are merely certain embodiments of the present invention and are not intended to be exhaustive. The specific embodiments described herein are merely illustrative and are not intended to limit the invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative work are within the scope of the present invention.

Embodiment 1

(6) As shown in FIG. 1 and FIG. 2, a container with a single-hand pressed foam pump head and emulsion pump head comprises bottle 6, and pump 4 filled with foam liquid or emulsion. Spring 5 is disposed in pump 4. Pump 4 comprises press head 1, connecting tube 2, fixed outflow cap 3, and air inflow controller. Fixed outflow cap 3 is disposed at the opening of bottle 6. Fixed outflow cap 3 is provided with a length of vertical connecting tube 2 and connected to a connecting end of bottle 6 through connecting tube 2. A connecting end of connecting tube 2 is fixedly connected to press head 1.

(7) When press head 1 is pressed down to move downward a certain distance relative to fixed outflow cap 3, plugged-in tube 21 moves into outflow chamber 31 for a certain depth such that pump 4 is in a working status, i.e., outflow status.

(8) When pump 4 is in the working status, a foam or liquid channel of connecting tube 2 is connected to a central outflow end of fixed outflow cap 3. Due to the pressure applied to press head 1, plugged-in tube 21 moves up and down in the channel of outflow chamber 31 of fixed outflow cap 3 and performs connection function, and suction tube 7 sucks the liquid repeatedly. Thus, the fixation of pump outlet with a single hand operation is achieved.

(9) The connecting structure between connecting tube 2 and fixed outflow cap 3 comprises the following technical features.

(10) Connecting tube 2 has a foam or liquid channel. A horizontal connecting channel is provided at the top of connection tube 2. The horizontal connecting channel is connected to a vertically downward plugged-in tube 21. When connecting tube 2 is pressed down such that plugged-in tube 21 is inserted in outflow chamber 31 of fixed outflow cap 3, connecting tube 2 and outflow chamber 31 forms a top outflow channel which is in a connecting state.

(11) Accordingly, plugged-in tube 21 and the liquid channel form an inverted U-shape conduit.

(12) In the container with a single-hand pressed foam pump head or emulsion pump head as described above, fixed outflow cap 3 is connected to bottle 6 through thread. External thread is provided at the opening of bottle 6. Internal thread is provided on the inner side of fixed outflow cap 3. Bottle 6 is connected to fixed outflow cap 3 through thread.

Embodiment 2

(13) As shown in FIG. 1 and FIG. 2, a single-hand pressed foam pump head comprises pump 4 filled with foam liquid or emulsion. Spring 5 is disposed in pump 4. Pump 4 comprises press head 1, fixed outflow cap 3. Fixed outflow cap 3 is provided with a vertical connecting tube 2 and connected to a connecting end of bottle 6 through connecting tube 2. Connecting tube 2 comprises a foam or liquid channel. A horizontal connecting channel is provided at the top of connection tube 2. The horizontal connecting channel is connected to a vertically downward plugged-in tube 21. When connecting tube 2 is pressed down such that plugged-in tube 21 is inserted in outflow chamber 31 of fixed outflow cap 3, connecting tube 2 and outflow chamber 31 connects with each other and forms a top outflow channel. One end of connecting tube 2 is partially embedded in hollow pump 4, the other end (outlet) of connecting tube 2 is inserted into a fixed outflow channel of fixed outflow cap 3 and can reciprocate therein.

(14) In addition, the container comprises press head 1, which is embedded above connecting tube 2. Press head 1 can reciprocate.

(15) An outflow outlet of pump 4 is connected to connecting tube 2 in a linkage connection.

(16) In the single-hand pressed foam pump head of the present invention, the user can put the index finger at the foam outlet of the nozzle and use the thumb to press the top of press head to some extent. During the pressing process, pump 4 is connected to the liquid channel of fixed outflow cap 3 and connecting tube 2 and is open. During the pressing process, connecting tube 2 moves downward to introduce the liquid or foam in pump 4 into the liquid channel of fixed outflow cap 3 to let the liquid or foam flow out.

(17) The foregoing description of the embodiments is intended to facilitate one of ordinary skill in the art to understand and apply the present invention. It will be apparent to those skilled in the art that various modifications may be made to these embodiments and that the generic principles described herein can be applied to other embodiments without creative work. Accordingly, the present invention is not limited to the above embodiments, and improvements and modifications, for example, size or diameter of tube, model of pump, position of outflow tube of outflow cap, etc., to the present invention by the skilled in the art in accordance with the present disclosure should be in the scope of protection of the invention if not going beyond the beneficial effects of the present invention.
