In the following, the most preferred embodiment of the present invention is described. In the drawings, thickness and spacing are expressed for convenience of description, and may be exaggerated compared to the actual physical thickness. In describing the present invention, well-known components that are not related to the gist of the present invention may be omitted. In adding reference numbers to the components of each drawing, it should be noted that only the same components are given the same number as possible even though they are indicated on different drawings.

2 is a cross-sectional view illustrating an internal structure of an eco-nonstop liquid dispenser according to an embodiment of the present invention.

And Figure 3 is a cross-sectional view for illustrating the docking process of the supply part of the eco-non-stop liquid dispenser according to an embodiment of the present invention.

1 to 3, the eco-nonstop liquid dispenser 1 (hereinafter, simply referred to as a 'dispenser') according to an embodiment of the present invention is a pump unit 10, a supply unit 20, and a control unit. (30).

First, a detailed look at the pump unit and the supply unit.

The pump unit 10 includes an internal storage 11 in which a liquid material (LD, see FIG. 7) can stay, and a pump 12 that discharges the liquid material to the outside through an upper outlet 121 according to an external pressure. ) has The liquid substance may be a variety of products used for similar purposes such as shampoo, conditioner, cosmetics, and the like. The pump 12 may be provided in a structure detachable from the internal storage 11 . Allows replacement of pumps that use very high usage compared to other parts.

The supply part 20 has a cap part 21 that can be coupled to the inlet thereof instead of the closure of the external container EC containing the liquid substance, and from the external container EC in the docked position DPO to the internal reservoir ( 11) has a pipe 22 that provides a flow path FT through which the liquid material LD naturally flows and moves. The outer container is a container containing shampoo, conditioner, cosmetics, etc., and may be a refillable container as well as a finished product.

The supply unit 20 further includes a coupling unit 23 having a structure capable of coupling/separating with the cap unit 21 . Therefore, the pipe 22 is connected to the cap part 21 through the coupling part 23 so that the liquid material LD contained in the external container EC passes through the cap part 21 and the coupling part 23 to the pump part 10 . It provides a flow path FT leading to the internal storage 11 of

In the docked position, the flow path is generally high on the supply side and low on the pump side, creating a natural flow by gravity.

The pipe 22 has one end 221 connected to the internal storage 11 which is a fixed end, and the other end 222 is connected to the coupling part 23 which is a free end. Specifically, a position at which one end 221 of the pipe is connected to the internal storage may be a connector part 112 provided under the internal storage. The connector part 112 has a structure communicating with the lower part of the internal storage 11 and provides a structure for connection with one end 221 of the pipe. The coupling part 23 also provides a structure for connection with the other end 222 of the pipe. Since the pipe is connected to the free end (eg, the connector part) and the fixed end (eg, the coupling part), the coupling between the cap part 21 and the inlet of the external container is not performed even when the coupling part 23 is out of the docking position (DPO). It becomes possible in all directions.

The supply part 20 further includes a mounting part 24 that provides a seating space MS for seating at least one of the cap part 21 and the coupling part 23 .

The mounting part 24 includes a plurality of wall parts W1, W2, W3 and a floor for fixing at least one of the cap part 21 and the coupling part 23 entering the seating space MS in the seating space MS. A withdrawal space LS (refer to FIG. 4 ) having a portion B and facing the internal storage 11 is provided between adjacent wall portions W2 and W3 among the plurality of wall portions. Accordingly, in the docking position DPO, the pipe 22 may be disposed in the withdrawal space LS.

The eco-nonstop liquid dispenser 1 further includes a lower case BC and an upper case TC. A pump unit 10 and a supply unit 20 are provided in the lower case BC. The upper case TC has a sleeve SL that partially surrounds the outer container EC at the upper portion of the lower case BC.

Hereinafter, the docking position (DPO) will be described in more detail.

The docking position DPO indicates a state in which the outer container EC is arranged to supply the liquid material LD to the dispenser 1 . The dispenser 1 has a structure so that the external container in the docking position can stably supply the liquid substance therein. Here, the cap part 21 , the pipe 22 and the coupling part 23 configured to be connected to the inlet ECE of the external container EC are involved. In addition, the mounting part 24 for stably mounting the cap part or the coupling part in the dispenser is involved.

Referring to FIG. 3 , a cap 21 that can be coupled to the inlet ECE is mounted in place of a stopper (not shown) of the outer container in a state in which the outer container EC is erected. It is assumed that the first outer container EC is mounted on the dispenser 1 for use of the dispenser. At this time, the external container EC is in a state in which the stopper is removed so that the contents LD can be supplied to the dispenser 1 , the other end 222 of the pipe 22 , that is, the cap portion 21 belonging to the free end is freely Because it is movable, it can be easily coupled to the external container inlet (ECE) in an upright state.

In this case, the reason that the cap part can move freely may be due to the fact that the pipe itself is made of a flexible material. Such a situation is well illustrated in the drawings. Alternatively, the freely movable cap portion may be derived from a connection relationship between the pipe and the fixed end (eg, connector portion) and free end (eg, coupling portion). The fixed end (connector part) has a structure that enables the rotation of one end of the pipe, and the free end (coupling part) has a structure that enables the rotation of the other end of the pipe. make it possible

Accordingly, even in a situation where the external container EC is initially mounted on the dispenser 1 , the user does not have to lift the external container upside down in a state in which the cap of the external container is opened is solved. It is possible to combine the cap part in an upright state. This completely eliminates the pouring phenomenon of the contents in the process of mounting the external container to the dispenser.

The outer container EC, which is connected to the coupling part 23 and the pipe 22, including the cap part 21, is turned over (in the FF direction shown in the figure) and enters the seating space MS of the mounting part 24 . Note that the state in which the outer container is turned upside down is a state in which its inlet is tightly closed by the cap portion and the coupling portion. The mounting part 24 provides a space for stably mounting the cap part and the coupling part coupled to the external container to the dispenser. It can have a variety of structures to make it possible.

4 shows a state in which the mounting part 24 is viewed from above according to an embodiment of the present invention. FIG. 5 shows a state in which the cap part 21 and the coupling part 23 are mounted on the mounting part of FIG. 4 . Note that in the drawing, the coupling part 23 is not shown because it is disposed in the lower seating space MSL through the opening O of the mounting part 24 . In addition, for convenience of explanation, the outer container is not shown in FIG. 5 . As the view of the cap part 21 from the top is shown, the flow path of the liquid material from the inlet of the external container through the cap part 21 and the coupling part 23 to the pipe 22 can be predicted. A portion referred to as H in the drawing indicates a hole (H) for inner communication with the coupling portion 23 of the cap portion 21 .

In the docking position DPO, the cap part 21 is provided so that its outer peripheral surface LF is in close contact with the plurality of wall parts W1, W2, and W3, and its lowermost surface BF is provided so that its outer peripheral surface LF is in close contact with the bottom part B . For this purpose, as will be described later, the outer diameter (D2, FIG. 6a) of the coupling part 23 is formed smaller than the outer diameter (D1, FIG. 6a) of the cap part 21, so that the cap part entering the seating space includes a plurality of wall parts and a floor It can be made to be seated in the seating space by being in close contact with the part.

Meanwhile, in the drawings, only the cap part is illustrated as having a structure in close contact with the mounting part as described above, but the present invention is not limited thereto. Alternatively, both the cap part and the coupling part may have a structure in close contact with the mounting part. In either case, the structure is common in that the cap or coupling part belonging to the free end is docked at a specific position, such as the fixed end on the left.

1 to 5 above, the cap part is coupled to the inlet of the external container in a standing state without fear of spilling the contents, and then the external container is turned over, and the coupling part connected to the pipe is docked by being seated as a mounting part together with the cap part. The position (DPO) is reached.

6A and 6B are diagrams for explaining in more detail the connection relationship between the cap part 21 and the coupling part 23 according to an embodiment of the present invention. In the drawings, piping is omitted for convenience of description.

6A and 6B , the cap part 21 and the coupling part 23 may have a screw coupling structure as a structure in which coupling/separation is possible. It is not limited to that shown in the drawings, and various structures may be applied for a structure capable of coupling/separating between the cap part (connected to the inlet of the external container) and the coupling part (connected to the pipe).

The cap portion 21 has a threaded structure therein for connection with the inlet of the external container. The outer diameter D1 of the cap part 21 has a fixed value designed for seating with the mounting part 24, and the inner diameters d1 and d2 may be varied to be compatible with the sizes of the inlets of various external containers. The inner diameter d2 of FIG. 6B is narrower than the inner diameter d1 of FIG. 6A , and thus the cap portion 21A of FIG. 6B may be compatible with an external container having a relatively narrow inlet. At this time, it is noted that the inner diameter CD for fastening with the coupling part 23 is consistently maintained in FIGS. 6A and 6B . That is, in order to have compatibility with the sizes of various external containers, it is sufficient that only the cap part is replaced.

The outer diameter D2 of the coupling part 23 also has a fixed value designed for seating with the mounting part 24 . In this case, the outer diameter D2 of the coupling part may be formed smaller than the outer diameter D1 of the cap part. This enables seating as shown in FIGS. 2 and 3 . Or, not limited thereto, the outer diameter of the coupling portion may be formed to be the same as the outer diameter of the cap portion. As described above, it is sufficient if it is determined in consideration of the mutual adhesion structure in relation to the seating space of the mounting part.

6c to 6e are views showing a more detailed structure of the coupling part 23 according to the embodiment of the present invention. First, referring to FIG. 6C , a needle part N may be provided on the inner bottom surface BS of the coupling part 23 . The needle part N may have a length in which the coupling part enters the inside of the cap part when the coupling part is coupled with the cap part. In some cases, this may serve to punch a spill prevention film (not shown) attached to the inlet of the external container, and may serve to facilitate the flow of the contents from the external container.

Referring to FIG. 6D , the needle part N may have a sharp tip CE so as to be advantageous for punching. In addition, openings (OPS) in the shape of openings that facilitate the flow of the contents from the external container may be provided in the body (BD) of the needle part. Rib parts RIB serving as a frame of the needle part itself may be provided between the openings. When the tip penetrates the spill-resistant membrane of the outer container and enters the body, the body spans the membrane, in which case openings provided in the body act to form a new flow path into the needle body body. If there are no openings, consider a situation where even if the membrane is pierced by the tip, the pierced part of the membrane is still blocked by the main body and the contents in it cannot escape properly.

The needle part N may have a cross-shaped tip in a plan view (see FIG. 6E ).

7 shows an example of an eco-non-stop liquid dispenser for explaining a control unit according to an embodiment of the present invention. And Figure 8 shows another example of the eco-non-stop liquid dispenser for explaining the control unit according to an embodiment of the present invention.

As shown in Figures 7 and 8, the control unit 30 is provided so that one end (E1) can be opened by the cock (CK), the other end (E2) from the external container (EC) of the liquid material (LD) It is connected to internal communication on the movement path to the internal storage (11). Accordingly, the control unit 30 adjusts the internal pressure of the external container EC in the docking position DPO to match the atmospheric pressure.

As the dispenser continues to be used, that is, as the pumping operation of the pump part continues, the liquid substance level L1 in the internal reservoir is lowered. The liquid substance is continuously supplied from the external container to the internal storage according to the height of the pump unit, the supply part, and the pipe, but as the liquid substance level (L3) in the external container decreases, the internal pressure inside the external container increases significantly. At this time, by opening the cock (CK) of the control unit 30, it is possible to lower the internal pressure increased in the external container.

As shown in FIG. 7 , one end E1 of the control unit is disposed adjacent to the upper portion of the pump unit, and the other end E2 of the control unit is configured such that the liquid material LD is transferred from the external container EC to the internal reservoir 11 . It may be connected to the lower part of the internal storage (eg, the connector part 112 ) close to the pump part on the moving path leading to it.

Alternatively, as shown in FIG. 8 , one end E1 of the control unit is disposed adjacent to the upper portion of the pump unit, and the other end E2 of the control unit is configured such that the liquid material LD is transferred from the outer container EC to the internal reservoir 11 . It may be connected to the coupling unit 23, for example, close to the supply unit on the moving path leading to the . In this case, it is preferable that the adjusting part has a flexible material so that the other end belongs to the free end together with the coupling part, or it is formed in a connection structure that enables free rotation in a connection relationship with the connector part or the coupling part.

On the other hand, in the drawing, the liquid material level (L2) of the control unit 30 is shown as not coincident with the liquid material level (L3) of the external container, but it is only for convenience of explanation, and the theoretical level (L2) is the level (L3) can match, and thus the cock CK serves to prevent the contents from overflowing through the end E1 so that the level L2 coincides with the level L3.

In addition, it is preferable that the forming height H of the one end E1 is higher than the height h1 of the liquid material level of the internal reservoir and lower than the sleeve SL of the upper case ( FIG. 2 ). This prevents an excessively raised arrangement of the one end E1 of the control unit, thereby enhancing the aesthetics of the dispenser and preventing the user from interfering with the pump.

The internal storage is formed of a material in which the contents are visible from the outside, and the amount of storage of the contents in the internal storage is visually external through the first window (WI) provided in the lower case and the second window (WO) provided in the upper case. It may be provided so that it can be checked. This notifies the user in advance of when to replace the exhausted outer container. Although the first window or the second window is shown with a transparent material (such as a transparent acrylic plate or glass) in the drawing, the present invention is not limited thereto, and if the inside can be seen from the outside, the first and second windows are opened without a transparent material ) in the form of an open type is sufficient.

Due to the design of the height of the pipe connected to the internal storage and the height of the pipe connected to the coupling part, a certain amount of content remains in the internal storage even when the contents of the external container are empty, increasing economic efficiency and serving as a non-stop dispenser makes it possible That is, the outer container is completely emptied so that it can be used economically, and a certain amount remains in the inner storage and serves as a buffer for a certain period of time until it is replaced with a new container, thereby enabling continuous liquid material to be dispensed.

The upper case is provided to be completely detachable from the lower case. All of the above-described pump unit, supply unit, and control unit may be provided in the lower case, and the upper case has a structure that can be completely separated from the pump unit, the supply unit and the control unit. This provides the convenience of only having to separate the upper case by the user in the process of replacing the outer container with a new container. It also provides a convenient extensible structure. 9 shows an expandable structure of an eco-nonstop liquid dispenser according to an embodiment of the present invention. The same description as that described above with reference to FIGS. 1 to 8 may be applied.

According to the embodiment of the present invention described above, by configuring the portion coupled to the external container to be freely rotatable, the contents are prevented from pouring when the external container is mounted. In addition, the internal pressure of the external container is adjusted to enable smooth supply. In addition, a certain amount of detergent is always stored by maintaining the negative pressure in the refill container at an appropriate level, ensuring continuity of use even if the replacement period is missed.

As described above, in the present invention, specific matters such as specific components, etc., and limited embodiments and drawings have been described, but these are only provided to help a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , various modifications and variations are possible from these descriptions by those of ordinary skill in the art to which the present invention pertains. Therefore, the spirit of the present invention should not be limited to the described embodiments, and not only the claims to be described later, but also all those with equivalent or equivalent modifications to the claims will be said to belong to the scope of the spirit of the present invention. .
