Description
DISPENSER FOR LIQUID CONTAINERS USABLE WITH ONE HAND
BACKGROUND OF THE INVENTION
Field of the Invention The present invention relates to a dispenser for liquid containers usable with one hand, and more particularly to a dispenser for liquid containers which includes a depressing member provided with an upper surface having an oval concave shape, and an extension member coupled at one end thereof to the outlet of a dispensing nozzle member, the extension member extending upwardly from one end thereof to have an upwardly curved arc shape having a desired radius of curvature in such a fashion that the other end thereof faces the upper surface of the depressing member while being vertically spaced from the upper surface of the depressing member, thereby allowing the user to manipulate the dispenser using one hand so as to dispense a liquid material contained in the container.
Description of the Prior Art Generally, containers for liquid soap or other liquid materials consist of a container body having a certain volume and a certain shape to receive a certain quantity of a liquid material therein, and a cap for closing a top opening of the container body. Where the user desires to use the liquid material contained in the container, he separates the cap from the container body to open the top opening of the container body, and then pours the liquid material from the container onto the palm of one hand. Thereafter, the user closes the top opening of the container body by coupling the cap to the container body in order to prevent the liquid material from being leaked from the container body. However, such containers are problematic in that it is very troublesome to use them because several hand maneuvers are required.
In order to solve such a problem, dispensers have recently been proposed which are configured to dispense a liquid material contained in a container by a pumping effect generated by a simple depressing manipulation of the user, as shown in Figs. 1 and 2.
Referring to Figs. 1 and 2, a dispenser 10 is illustrated. The dispenser 10 includes a container 20 contained with a certain quantity of a liquid material such as liquid soap and provided at an opened upper end thereof with a coupling portion 22, a cap 30 threadedly coupled to the coupling portion 22 of the container 20 and centrally provided with a through hole 32, and a pumping unit 40 fitted in the through hole 32 of the cap 30 and adapted to outwardly pump the liquid material from the container 20.
The pumping unit 40 includes a cylindrical upper body 42 rotatably fitted in the through hole 32 of the cap 30, and a pipe-shaped lower body 44 fitted around the upper body 42 in the interior of the container 20. A pipe-shaped feeding member 46 is fitted in the upper body 42 in such a fashion that it extends downwardly into the interior of the lower body 44 at its lower end while being outwardly protruded from the upper body 42 at its upper end. A depressing member 48 is coupled to the upper end of the feeding member 46 in such a fashion that it communicates with the feeding member 46. The depressing member 48 is provided at one side portion thereof with a dispensing nozzle member 48a. A pad 50 is fitted around the lower end of the feeding member 46 in the interior of the lower body 44. A pad fixing member 52 is fitted in the lower end of the pad 50 in such a fashion that its upper end is inserted into the interior of the feed member 46. The pumping unit 40 also includes a compression coil spring 54 installed in the lower body 44 and adapted to apply an upward spring force to the pad fixing member 52, and a ball 56 seated on a hole formed at the lower end of the lower body 44 and adapted to selectively close the hole.
When the user depresses the upper surface of the depressing member 48 in a state in which the pumping unit 40 is coupled to the container 20, the feeding member 46 coupled to the depressing member 48 moves downwardly. By the downward movement of the feeding member 46, the pad 50 moves downwardly while being in contact with the inner circumferential surface of the lower body 44. As a result, the compression coil spring 56 is downwardly compressed while applying a downward spring force to the ball 56, thereby causing the ball 56 to close the hole formed at the lower end of the lower body 44.
At this time, the liquid material present in the interior of the lower body 44 is introduced into the feeding member 46 between the pad 50 and pad fixing member 52 by virtue of a compressive force applied thereto by the pad 50. Thus, the liquid material is pumped to the dispensing nozzle member 48a of the depressing member 48.
When the external force applied to the depressing member 48 is released in the above state, the compression coil spring 54 is upwardly extended while applying an upward spring force to the pad fixing member 52. As a result, the pad 50 moves upwardly while being in contact with the inner circumferential surface of the lower body 44. This movement generates a suction force in the interior of the lower body 44, thereby causing the liquid material contained in the container 20 to be sucked into the interior of the lower body 44 through the lower hole of the lower body 44.
Thus, a desired quantity of liquid material can be dispensed from the container 20 through the dispensing nozzle member 48a as the user repeatedly depresses the depressing member 48 of the dispenser 10 by one hand. The user receives the dispensed liquid material onto the other hand to use the liquid material.
However, such a dispenser having the above mentioned construction is inconvenient in use because its dispensing nozzle member is laterally protruded from the depressing member, thereby forcing the user to use both hands in such a fashion that he depresses the depressing member by one hand while receiving the dispensed liquid material onto the other hand. Furthermore, it is impossible for disabled persons, who may have the use of only one hand, to use the above mentioned dispenser.
SUMMARY OF THE INVENTION
Therefore, the present invention has been made in view of the above mentioned problems, and an object of the invention is to provide a dispenser for liquid containers which has a configuration allowing both the operation of depressing a depressing member to pump a liquid material from a container and the operation of receiving the pumped liquid material to be achieved by one hand of the user.
In accordance with the present invention, this object is accomplished by providing a dispenser for a liquid container usable with one hand comprising a cap adapted to close a top opening of a container, to which the dispenser is applied, and a pumping unit mounted to the cap and provided with a depressing member and a dispensing nozzle member formed at the depressing member, the pumping unit being configured in such a fashion that when the depressing member is depressed, a sucking force is generated in the pumping unit, thereby sucking a liquid material from the container and dispensing the sucked liquid material through the dispensing nozzle member, further comprising: a depressing surface provided at an upper surface of the depressing member, the depressing surface having an oval concave shape; and an extension member coupled at one end thereof to an outlet of the dispensing nozzle member, the extension member extending upwardly from one end thereof to have an upwardly curved arc shape having a desired radius of curvature in such a fashion that the other end thereof faces the upper surface of the depressing member while being vertically spaced from the upper surface of the depressing member, whereby the liquid material sucked by a depressing force applied to the depressing member is downwardly discharged through the extension member.
BRIEF DESCRIPTION OF THE DRAWINGS
Other objects and aspects of the invention will become apparent from the following description of embodiments with reference to the accompanying drawings in which:
Fig. 1 is a perspective view illustrating a conventional dispenser for liquid containers;
Fig. 2 is a sectional view illustrating an operating condition of the conventional dispenser;
Fig. 3 is a perspective view illustrating a dispenser for liquid containers which has a configuration allowing the dispenser to be used by one hand of the user in accordance with an embodiment of the present invention;
Fig. 4 is a sectional view illustrating an operating condition of the dispenser according to the embodiment of the present invention; and Fig. 5 is a perspective view illustrating a dispenser for liquid containers which has a configuration allowing the dispenser to be used by one hand of the user in accordance with another embodiment of the present invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
Fig. 3 is a perspective view illustrating a dispenser for liquid containers which has a configuration allowing the dispenser to be used by one hand of the user in accordance with an embodiment of the present invention. Fig. 4 is a sectional view illustrating an operating condition of the dispenser according to the embodiment of the present invention.
Referring to Figs. 3 and 4, the dispenser, which is denoted by the reference numeral 100, includes a cap 110 adapted to close the top opening of a container (not shown) to which the dispenser 100 is applied. The dispenser 100 also includes a pumping unit 130 mounted to the cap 110 and provided with a depressing member 120 and a dispensing nozzle member 122 formed at the depressing member 120. The pumping unit 130 is configured in such a fashion that when the depressing member 120 is depressed, a sucking force is generated in the pumping unit 130, thereby sucking a liquid material from the container and dispensing the sucked liquid material through the dispensing nozzle member 122. Such a configuration is similar to those of conventional dispensers.
In accordance with the present invention, the depressing member 120 is provided at its upper surface with a depressing surface 120a having an oval concave shape. An extension member 140 is coupled at one end thereof, namely, an inlet thereof, to an outlet of the dispensing nozzle member 122. In the illustrated case, the extension member 140 is integral with the dispensing nozzle member 122. The extension member 140 extends upwardly from its one end to have an upwardly curved arc shape having a desired radius of curvature in such a fashion that the other end thereof, namely, an outlet thereof, faces the upper surface of the depressing member 120 while being spaced from the upper surface of the depressing member 120.
Preferably, the extension member 140 has a semicircular shape having a desired radius of curvature in such a fashion that the outlet thereof is arranged above the central portion of the depressing member 120 while defining a dispensing direction downwardly directed at an angle of about 15° with respect to a horizontal line. Of course, the dispensing angle of the extension member 140 is not limited to the above angle.
For the extension member 140, various dispensing angles may be _g_ used. Also, the configuration for pumping the liquid material contained in the container is not limited to the configuration as illustrated. In accordance with the present invention, a variety of pumping configurations may be used within the scope of the present invention.
Preferably, the space between the outlet of the extension member 140 and the upper surface of the depressing member 120 has a distance allowing the left or right hand of an adult, who has an average hand size, to freely access the space.
Fig. 5 is a perspective view illustrating a dispenser for liquid containers which has a configuration allowing the dispenser to be used by one hand of the user in accordance with another embodiment of the present invention. In accordance with this embodiment, the extension member 140 is configured in such a fashion that it is separable from the dispensing nozzle member 122. That is, an annular engagement protrusion 124 is formed on the outer circumferential surface of the outlet portion of the dispensing nozzle member 122 whereas an annular engagement groove 142, which is engagable with the annular engagement protrusion 124, is formed on the inner circumferential surface of the inlet portion of the extension member 140. Thus, the extension member 140 is rotatably coupled to the dispensing nozzle member 122.
The configuration for rotatably and separably coupling the extension member 140 to the dispensing nozzle member 122 is not limited to the illustrated configuration. Various configurations may be applied within the scope of the present invention.
Now, the operation and effect of the dispenser for liquid containers, which has the above mentioned configuration according to the present invention, will be described.
Where the user desires to use the dispenser 100 provided at the depressing member 120 with the extension member 140, he first inserts one hand into the space defined between the upper surface of the depressing member 120 and the outlet of the extension member 140 in such a fashion that the palm of the hand faces the outlet of the extension member 140.
Thereafter, the user downwardly depresses the depressing member 120 in a state in which the back of the hand is in contact with the depressing surface 120a of the depressing member 120. As a result, the liquid material contained in the container is pumped by the pumping unit 130. The pumped liquid material flows along the extension member 140 and is then discharged from the extension member 140 onto the palm of the hand depressing the depressing member 120. Thus, the discharged liquid material is collected onto the hand of the user.
In this state, the user retracts the hand from the space between the depressing surface 120a of the depressing member 120 and the extension member 140, so that he can use the liquid material collected onto the hand.
Thus, the user can conduct both the operation of depressing the depressing member to pump the liquid material from the container and the operation of receiving the pumped liquid material by one hand.
Since the extension member 140 may have a separable and rotatable construction, it can contribute to a convenient storage or transportation of the dispenser when it is in a downwardly inverted state. The extension member 140 can also be removed from the dispenser when it is unnecessary. In this case, the dispensing nozzle member 122 serves to directly dispense the liquid material.
As apparent from the above description, the present invention provides a dispenser for liquid containers which has a configuration allowing both the operation of depressing a depressing member to pump a liquid material from a container and the operation of receiving the pumped liquid material to be achieved by one hand of the user. Accordingly, the dispenser provides convenience in the use of the dispenser.
In particular, the dispenser of the present invention is very useful for disabled persons who may not be able to use one hand.
Although the preferred embodiments of the invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.

Description of the Prior Art Generally, containers for liquid soap or other liquid materials consist of a container body having a certain volume and a certain shape to receive a certain quantity of a liquid material therein, and a cap for closing a top opening of the container body. Where the user desires to use the liquid material contained in the container, he separates the cap from the container body to open the top opening of the container body, and then pours the liquid material from the container onto the palm of one hand. Thereafter, the user closes the top opening of the container body by coupling the cap to the container body in order to prevent the liquid material from being leaked from the container body. However, such containers are problematic in that it is very troublesome to use them because several hand maneuvers are required.
In order to solve such a problem, dispensers have recently been proposed which are configured to dispense a liquid material contained in a container by a pumping effect generated by a simple depressing manipulation of the user, as shown in Figs. 1 and 2.
Referring to Figs. 1 and 2, a dispenser 10 is illustrated. The dispenser 10 includes a container 20 contained with a certain quantity of a liquid material such as liquid soap and provided at an opened upper end thereof with a coupling portion 22, a cap 30 threadedly coupled to the coupling portion 22 of the container 20 and centrally provided with a through hole 32, and a pumping unit 40 fitted in the through hole 32 of the cap 30 and adapted to outwardly pump the liquid material from the container 20.
The pumping unit 40 includes a cylindrical upper body 42 rotatably fitted in the through hole 32 of the cap 30, and a pipe-shaped lower body 44 fitted around the upper body 42 in the interior of the container 20. A pipe-shaped feeding member 46 is fitted in the upper body 42 in such a fashion that it extends downwardly into the interior of the lower body 44 at its lower end while being outwardly protruded from the upper body 42 at its upper end. A depressing member 48 is coupled to the upper end of the feeding member 46 in such a fashion that it communicates with the feeding member 46. The depressing member 48 is provided at one side portion thereof with a dispensing nozzle member 48a. A pad 50 is fitted around the lower end of the feeding member 46 in the interior of the lower body 44. A pad fixing member 52 is fitted in the lower end of the pad 50 in such a fashion that its upper end is inserted into the interior of the feed member 46. The pumping unit 40 also includes a compression coil spring 54 installed in the lower body 44 and adapted to apply an upward spring force to the pad fixing member 52, and a ball 56 seated on a hole formed at the lower end of the lower body 44 and adapted to selectively close the hole.
When the user depresses the upper surface of the depressing member 48 in a state in which the pumping unit 40 is coupled to the container 20, the feeding member 46 coupled to the depressing member 48 moves downwardly. By the downward movement of the feeding member 46, the pad 50 moves downwardly while being in contact with the inner circumferential surface of the lower body 44. As a result, the compression coil spring 56 is downwardly compressed while applying a downward spring force to the ball 56, thereby causing the ball 56 to close the hole formed at the lower end of the lower body 44.
At this time, the liquid material present in the interior of the lower body 44 is introduced into the feeding member 46 between the pad 50 and pad fixing member 52 by virtue of a compressive force applied thereto by the pad 50. Thus, the liquid material is pumped to the dispensing nozzle member 48a of the depressing member 48.
When the external force applied to the depressing member 48 is released in the above state, the compression coil spring 54 is upwardly extended while applying an upward spring force to the pad fixing member 52. As a result, the pad 50 moves upwardly while being in contact with the inner circumferential surface of the lower body 44. This movement generates a suction force in the interior of the lower body 44, thereby causing the liquid material contained in the container 20 to be sucked into the interior of the lower body 44 through the lower hole of the lower body 44.
Thus, a desired quantity of liquid material can be dispensed from the container 20 through the dispensing nozzle member 48a as the user repeatedly depresses the depressing member 48 of the dispenser 10 by one hand. The user receives the dispensed liquid material onto the other hand to use the liquid material.
However, such a dispenser having the above mentioned construction is inconvenient in use because its dispensing nozzle member is laterally protruded from the depressing member, thereby forcing the user to use both hands in such a fashion that he depresses the depressing member by one hand while receiving the dispensed liquid material onto the other hand. Furthermore, it is impossible for disabled persons, who may have the use of only one hand, to use the above mentioned dispenser.

Therefore, the present invention has been made in view of the above mentioned problems, and an object of the invention is to provide a dispenser for liquid containers which has a configuration allowing both the operation of depressing a depressing member to pump a liquid material from a container and the operation of receiving the pumped liquid material to be achieved by one hand of the user.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Fig. 3 is a perspective view illustrating a dispenser for liquid containers which has a configuration allowing the dispenser to be used by one hand of the user in accordance with an embodiment of the present invention. Fig. 4 is a sectional view illustrating an operating condition of the dispenser according to the embodiment of the present invention.
Referring to Figs. 3 and 4, the dispenser, which is denoted by the reference numeral 100, includes a cap 110 adapted to close the top opening of a container (not shown) to which the dispenser 100 is applied. The dispenser 100 also includes a pumping unit 130 mounted to the cap 110 and provided with a depressing member 120 and a dispensing nozzle member 122 formed at the depressing member 120. The pumping unit 130 is configured in such a fashion that when the depressing member 120 is depressed, a sucking force is generated in the pumping unit 130, thereby sucking a liquid material from the container and dispensing the sucked liquid material through the dispensing nozzle member 122. Such a configuration is similar to those of conventional dispensers.
In accordance with the present invention, the depressing member 120 is provided at its upper surface with a depressing surface 120a having an oval concave shape. An extension member 140 is coupled at one end thereof, namely, an inlet thereof, to an outlet of the dispensing nozzle member 122. In the illustrated case, the extension member 140 is integral with the dispensing nozzle member 122. The extension member 140 extends upwardly from its one end to have an upwardly curved arc shape having a desired radius of curvature in such a fashion that the other end thereof, namely, an outlet thereof, faces the upper surface of the depressing member 120 while being spaced from the upper surface of the depressing member 120.
Preferably, the extension member 140 has a semicircular shape having a desired radius of curvature in such a fashion that the outlet thereof is arranged above the central portion of the depressing member 120 while defining a dispensing direction downwardly directed at an angle of about 15° with respect to a horizontal line. Of course, the dispensing angle of the extension member 140 is not limited to the above angle.
For the extension member 140, various dispensing angles may be _g_ used. Also, the configuration for pumping the liquid material contained in the container is not limited to the configuration as illustrated. In accordance with the present invention, a variety of pumping configurations may be used within the scope of the present invention.
Preferably, the space between the outlet of the extension member 140 and the upper surface of the depressing member 120 has a distance allowing the left or right hand of an adult, who has an average hand size, to freely access the space.
Fig. 5 is a perspective view illustrating a dispenser for liquid containers which has a configuration allowing the dispenser to be used by one hand of the user in accordance with another embodiment of the present invention. In accordance with this embodiment, the extension member 140 is configured in such a fashion that it is separable from the dispensing nozzle member 122. That is, an annular engagement protrusion 124 is formed on the outer circumferential surface of the outlet portion of the dispensing nozzle member 122 whereas an annular engagement groove 142, which is engagable with the annular engagement protrusion 124, is formed on the inner circumferential surface of the inlet portion of the extension member 140. Thus, the extension member 140 is rotatably coupled to the dispensing nozzle member 122.
The configuration for rotatably and separably coupling the extension member 140 to the dispensing nozzle member 122 is not limited to the illustrated configuration. Various configurations may be applied within the scope of the present invention.
Now, the operation and effect of the dispenser for liquid containers, which has the above mentioned configuration according to the present invention, will be described.
Where the user desires to use the dispenser 100 provided at the depressing member 120 with the extension member 140, he first inserts one hand into the space defined between the upper surface of the depressing member 120 and the outlet of the extension member 140 in such a fashion that the palm of the hand faces the outlet of the extension member 140.
Thereafter, the user downwardly depresses the depressing member 120 in a state in which the back of the hand is in contact with the depressing surface 120a of the depressing member 120. As a result, the liquid material contained in the container is pumped by the pumping unit 130. The pumped liquid material flows along the extension member 140 and is then discharged from the extension member 140 onto the palm of the hand depressing the depressing member 120. Thus, the discharged liquid material is collected onto the hand of the user.
In this state, the user retracts the hand from the space between the depressing surface 120a of the depressing member 120 and the extension member 140, so that he can use the liquid material collected onto the hand.
Thus, the user can conduct both the operation of depressing the depressing member to pump the liquid material from the container and the operation of receiving the pumped liquid material by one hand.
Since the extension member 140 may have a separable and rotatable construction, it can contribute to a convenient storage or transportation of the dispenser when it is in a downwardly inverted state. The extension member 140 can also be removed from the dispenser when it is unnecessary. In this case, the dispensing nozzle member 122 serves to directly dispense the liquid material.
As apparent from the above description, the present invention provides a dispenser for liquid containers which has a configuration allowing both the operation of depressing a depressing member to pump a liquid material from a container and the operation of receiving the pumped liquid material to be achieved by one hand of the user. Accordingly, the dispenser provides convenience in the use of the dispenser.
In particular, the dispenser of the present invention is very useful for disabled persons who may not be able to use one hand.
Although the preferred embodiments of the invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
