       [0001]    This application is a national phase and a Continuation in Part of PCT application No. PCT/IL2012/000168 filed on Apr. 24, 2012, which claims priority to Israeli patent application No. 212584 filed on Apr. 28, 2010, both of which are incorporated herein by reference in their entirety. 
     
    
     Field of the Invention 
       [0002]    The present invention relates to the field of pump dispensers. More particularly, the invention relates to a universal connector to dip tubes of pump dispensers and pump dispensers with such connectors. 
       BACKGROUND OF THE INVENTION 
       [0003]    An atomizer is a device which converts a stream of liquid into a fine mist spray. Atomizers are used in the perfume and pharmaceutical industries, as well as cleaning supplies, painting, cosmetics, and more. Atomizers might be known by another name, such as squirt bottles, inhalers for medications, cooking sprays, perfume bottles which emit a mist, and other. 
         [0004]    A common atomizer has several components. The first is a sealed bottle containing the liquid to be sprayed. At the top thereof is disposed a nozzle. The nozzle is connected to a tube dipped in the liquid to be sprayed, jell or cream to be poured, and so on. By compressing the air inside the bottle, the liquid/jell disposed therein is pushed out of the bottle through the tube dipped therein, and is sprayed/poured out of the bottle via the nozzle. 
         [0005]    Actually, it is an example of a pumping mechanism that employs a tube for pumping fluid disposed in a container. 
         [0006]    One of the problems regarding a tube dipped in a fluid to be pumped is that the tube cannot pump the entire content of the container. For example, as the fluid/jell/cream inside the container exhausts, the dispensed substance draws away from the end of the tube, and therefore it cannot pump the entire content of the container. Furthermore, even if the tube reaches to the bottom of the container, turning the container several degrees results with concentrating of the substance at one side of the container, which may be the side where the tube does not reaches to. 
         [0007]    U.S. 2004/0206775A1 discloses a pump dispenser having a plurality of compartments with dip tubes extending into each of the compartments. 
         [0008]    U.S. 2008/0264977A1 describes a pump dispenser having an extraction tube, one end of which is connected to the pump and the other end divided into two extraction tubes of different length. 
         [0009]    U.S. 2011/0011895A1 teaches a pump dispenser with a dip tube whose tip portion is spread at the lower end. 
         [0010]    It is an object of the present invention to provide a solution to the above-mentioned and other problems of the prior art. 
         [0011]    Other objects and advantages of the invention will become apparent as the description proceeds.

       [0055]    It should be understood that the drawings are not necessarily drawn to scale. 
       DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0056]    The present invention will be understood from the following detailed description of preferred embodiments, which are meant to be descriptive and not limiting. For the sake of brevity, some well-known features, methods, systems, procedures, components, circuits, and so on, are not described in detail. 
         [0057]      FIG. 1  schematically illustrates a cosmetic bottle  10  using a universal connector  18 , according to one embodiment of the invention. 
         [0058]    In this example, container  14  is transparent, in order to reveal the bushing disposed therein. 
         [0059]    The cosmetic bottle, which is marked herein by reference numeral  10 , is a container employing a dip tube  16 , in which at the end thereof is installed a bushing  20  from which a plurality of tubes  24  extend. Thus, dip tube  16  is extended with a plurality of tubes  24 , which the end thereof is disposed at the bottom of container  14 . Due to the length of each extending tube, the end thereof touches the bottom of container  14 , thereby enabling pumping the substance disposed at the bottom of the container. The plurality of tubes that reach to the bottom of the container increases the chance that if one of the extending tubes is blocked, other tubes are still open. 
         [0060]    This advantage is achieved by ensuring that the end of each of extending tubes  24  reaches closer to the bottom of container  14 , in comparison to the prior art in which the end of the dip tube not necessarily touches the bottom of the container. In order to place the end of each of extending tubes  24  at the bottom of the container, the length of extending tubes  24  should be large enough. 
         [0061]    Furthermore, at the end of each of extending tubes  24  is disposed a spacer, which prevents blocking the extending tube thereof by the bottom of the container, by maintaining a space between the end of an extending tube  24  and the bottom of container  14 . The spacer is marked herein by reference numeral  28 , and is better seen in the zoomed view of  FIG. 4 . 
         [0062]      FIG. 2  schematically illustrates bushing  20 , which is illustrated also in  FIG. 1 . 
         [0063]    Bushing  20  is in a form of a “universal” connector, i.e., a mechanism that allows connecting thereof to dip tubes of different external diameters. 
         [0064]    A “universal” mechanism may be, for example, an elastic structure of bushing  20 , thereby allowing fine adjusting of the diameter thereof, in order to fit to the outer side of a dip tube to be connected therein. The connection is made by inserting the dip tube into bore  22  of bushing  20 . 
         [0065]    Tubes  24  are designed to be flexible, in order to allow bending thereof such that the end of each extending tubes  24  will reach to the bottom of the container. 
         [0066]      FIG. 3  schematically illustrates bushing  20  while connecting to dip tube  16  of a pump which pumping arm  12  belongs to. Reference numeral  34  denotes arrows illustrating pipe  16  and bushing  20  approaching each other, in order to connect. 
         [0067]      FIG. 4  schematically illustrates dip tube  16  mated with bushing  20  of universal connector  18 . 
         [0068]    The zoomed view illustrates the end of tube  24 , which is designed as a spacer for ensuring a space between the bottom of a pump&#39;s container and tube  24 , in order to prevent blocking the tube. 
         [0069]    The spacer is embodied in this illustration as an extension of the tube, but not along the entire extent thereof, thereby leaving a space  26  between the edge of the tube and the bottom of a container thereof. 
         [0070]    Of course, this is merely an example of a spacer, and other spacers can be employed for achieving the same object. 
         [0071]      FIG. 5  schematically illustrates the universal connector  18  of  FIG. 1 , from a different angle. 
         [0072]    From this angle, the structure of bushing  20  is further detailed. As illustrated, bushing  20  comprises a plurality of inner cylinders (bores), each having different diameter. The bores are marked in this figure by reference numerals  22 A,  22 B and  22 C. The cylinders (bores) are arranged in a subsequent order, according to their diameter. 
         [0073]    This form enables inserting therein pipes of different external diameters, i.e., rendering bushing  20  a universal connector. 
         [0074]    In addition, bushing  20  may be made of rubber of other elastic material, thereby sealing the space between a dip tube  16  and the bushing. 
         [0075]      FIG. 6  schematically illustrates a universal connector  18 ′, according to another embodiment of the invention. 
         [0076]    According to this embodiment, extending tubes  24  are arranged in a subsequent order, in order to fit to an elongated bottom container. 
         [0077]    The zoomed view focuses on an end of extending tube  24 , which comprises spacer  28 . 
         [0078]      FIG. 7  schematically illustrates a packing of a universal connector, according to one embodiment of the invention. 
         [0079]    The packing, which is marked herein by reference numeral  30 , may be a plastic bag and the like. 
         [0080]    Extending tubes  24  are bundled by a belt  32 . The closing mechanism of belt  32  may be, for example, a Velcro fastener. This way the tubes can be inserted into a container (as they are gathered), and thereafter, while the extending tubes are inserted in the container, the belt can be opened. 
         [0081]      FIG. 8  schematically illustrates a cosmetic bottle  10  using a dip tube ( 16 ) extending to a plurality of extending tubes ( 24 ), according to another embodiment of the invention. 
         [0082]    According to this embodiment of the invention, the universal connector is embedded in dip tube  16  of a pump rather than connected thereto by a bushing. Thus, such a tube may be manufactured, rather than leaving a user to connect a universal connector to a pump&#39;s tube. 
         [0083]    In the figures and/or description herein, the following reference numerals have been mentioned:
   numeral  10  denotes a cosmetic bottle, as an example of a pump;   numeral  12  denotes an arm, by which a user applies force on a pump thereof to pump;   numeral  14  denotes a container from which a substance is pumped;   numeral  16  denotes a dip tube of a pump;   numeral  18  denotes a universal connector for a pump, according to one embodiment of the invention;   numeral  18 ′ denotes a universal connector for a pump, according to another embodiment of the invention;   numeral  20  denotes a bushing, which is used as a universal connector connecting a dip tube  16  and extending tubes  24 ;   each of numerals  22 ,  22 A,  22 B, and  22 C denotes an opening of different diameter of bushing  20 , thereby allowing a “universal” operation of bushing  20 ;   numeral  24  denotes an extending tube of a universal connector;   numeral  26  denotes a space between the end of the tube and the bottom of a container thereof;   numeral  28  denotes a spacer;   numeral  30  denotes a packing of universal connector;   numeral  32  denotes a belt for bundling extending tubes  24  of universal connector  18 ; and   numeral  34  denotes arrows illustrating pipe  16  and bushing  20  approaching each other, in order to connect.   
 
         [0098]    FIGS.  9 A,B,C,D and E schematically illustrates a cosmetic bottle  10  using a dip tube ( 16 ) extending to a plurality of extending tubes ( 24 ), according to another embodiment of the invention. 
         [0099]    According to this embodiment the extending tubes  24  and the dip tube ( 16 ) are manufacture as one piece. The extending tubes are spaced one from the other, each stretching at different angle from the side of the dip tube ( 16 ), Each extending tube  24  edge has special design  40 , having funnel shape. This shape specially designed to prevent air bubbles around the extending tube  24  ends when dispensing substance which has density higher than liquid such as cream. 
         [0100]      FIG. 10  schematically illustrates an enlarge bottom view of a cosmetic bottle  10  using a dip tube ( 16 ) extending to a plurality of extending tubes ( 24 ), according to another embodiment of the invention. 
         [0101]      FIG. 11  schematically illustrates perspective side a dip tube ( 16 ) extending to a plurality of extending tubes ( 24 ) having edge  40 , according to another embodiment of the invention. The edge of the tube  40  is specially designed such as to form a recess (space) between the bottom surface of the container  14  and the circumference of the tube edge  40  to allow intake of fluid/gel in the container into the dip tube  16 . This means that only one or more parts of the edge rim of each extension tube  24  engages the bottom surface of the container  14  and one or more other parts will always be elevated therefrom to allow the substance (e.g. liquid/gel) of the container XX to flow therein. In the embodiment shown in  FIG. 11 , the edge of the extension tube  24  is truncated in a sloped curved manner. In other embodiments such as shown in  FIG. 6  each extension tube  24  includes several recesses cut  26  from a flat edge forming openings through which liquid/gel can be taken. 
         [0102]      FIG. 12  schematically illustrates perspective bottom view a dip tube ( 16 ) extending to a plurality of extending tubes ( 24 ) having edge  40 , according to one embodiment of the invention.
