Liquid discharge guiding structure and its pressing liquid discharge device and liquid discharge container

Abstract

This invention provides a liquid dispensing structure, a press-to-dispense device, and a dispensing container. The liquid dispensing structure includes a sleeve made of an elastic material. One end of the sleeve has a plurality of movable flaps that are closed when not dispensing. The other end of the sleeve has a connecting portion, one end of which connects to the other end of the plurality of movable flaps. The other end of the connecting portion is an open connector. In the dispensing state, the plurality of movable flaps form a dispensing opening, and after the dispensing state is released, they automatically return to a closed state due to the resilience of the elastic material. The connector of the liquid dispensing structure can be installed at the liquid outlet of the press-to-dispense device and applied to the dispensing container. This reduces the contact between the liquid outlet and the outside air and prevents viscous liquids from drying out or becoming blocked due to moisture evaporation.

Claims

1. A liquid outflow guiding structure, comprising: A sleeve, formed of an elastic material, has a plurality of movable flaps at one end, which taper to a closed shape with their edges abutting each other. The other end of the sleeve has a connecting portion, one end of which connects to the other end of the plurality of movable flaps, and the other end of which is an open sleeve. When liquid is dispensing, one end of the plurality of movable flaps forms a liquid outlet from the closed shape, and when liquid dispensing stops, the plurality of movable flaps return to the closed shape.

2. The liquid outlet guiding structure as described in claim 1, wherein the socket is circular.

3. The liquid outlet guiding structure as described in claim 1, wherein the socket is rectangular.

4. The liquid outlet guiding structure as claimed in claim 1, wherein the elastic material is one of silicone, rubber or thermoplastic elastomer.

5. A press-to-dispense device, comprising: A press-operated liquid dispenser includes: a press head, one end of which has a liquid outlet and the other end of which has a liquid inlet, the liquid outlet and the liquid inlet being connected; a squeezer, one end of which is connected to the liquid inlet; and a liquid flow guiding structure as described in any one of claims 1 to 4, wherein the sleeve is fitted onto the liquid outlet; wherein the press head is pressed to drive the squeezer, the other end of which draws liquid, the liquid flows through the liquid inlet (i.e., the liquid outlet) to a plurality of movable flaps, causing one end of the plurality of movable flaps to be in a liquid dispensing state, thus forming the liquid dispensing opening from the closed state; and when the press head stops driving the squeezer, i.e., the liquid dispensing state stops, the plurality of movable flaps return to the closed state.

6. A liquid outlet container, comprising: A container having a container opening at one end and a first connecting portion outside the container opening; and a press-to-dispense device as described in claim 5, wherein a second connecting portion is provided around the periphery of the press head, the second connecting portion being connected to the first connecting portion, allowing the press head to be connected to the container, and the other end of the squeezer extending to a predetermined distance from the bottom of the container; wherein the press head is pressed to drive the squeezer, the other end of the squeezer drawing liquid stored in the container, the liquid flowing through the liquid inlet and the liquid outlet to the plurality of movable flaps, causing one end of the plurality of movable flaps to be in a liquid dispensing state, thus forming the liquid dispensing opening from the closed state; and when the press head stops driving the squeezer, i.e., the liquid dispensing state stops, the plurality of movable flaps return to the closed state.
