Title: Sealed medicine dropper containing a liquid

Description:
BACKGROUND OF THE INVENTION  
      (a) Technical Field of the Invention  
      The present invention relates to a dropper, and in particular, a medicine dropper for containing a liquid medicine for children or old patients. The sealed dropper is disposed after use.  
      (b) Description of the Prior Art  
      Conventionally, medicines are placed on a spoon from a container or onto a small cup with scale measurement. However, the accuracy of the medicine is rather difficult to control, and the pouring of medicine onto a spoon is laborious. As shown in  FIG. 1 , a dropper  10 ′ is used and the medicine is enclosed within the dropper  10 ′. However, after one application, the dropper  10 ′ has to be cleaned for next application. In addition, the bottle containing medicine will not be used within a specific period. If the medicine is to be kept for further application, the bottle must be sealed. The drawback of the conventional dropper is that the whole bottle of medicine has to be carry along which is not convenient and there is a possible of misplaced the medicine. Accordingly, it is an object of the present invention to provide a medicine dropper which is sealed, which mitigates the above drawback.  
     SUMMARY OF THE INVENTION  
      The primary purpose of the present invention is to provide a sealed medicine dropper having a tube body containing a liquid comprising a tube opening having a mouth section with a smaller diameter and the mouth section extended upwardly to pivotally mount with the tube body; the tube body being an extension from the tube opening with a larger tube diameter so as to fill a liquid; and a head end being a ball-like body at the rear end of the tube body and having a wall thickness smaller than that of the tube body facilitating depressing action of the fingers.  
      Yet another object of the present invention is to provide a sealed medicine dropper containing a liquid, wherein the mouth section of the tube opening is sealed with a foil.  
      Sill another object of the present invention is to provide a sealed medicine dropper containing a liquid, wherein the mouth section of the tube opening is provided with a score mark facilitating breakage of the tube opening.  
      A further object of the present invention is to provide a sealed medicine dropper containing a liquid, wherein the mouth section of the tube opening is threaded and is capped with a cap having inner threads, so as to seal the tube opening.  
      The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.  
      Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.  
      Referring to  FIG. 2 , there is shown a dropper  10  comprising a tube opening  11  having a mouth section  1101  with a smaller diameter, and the mouth section  1101  mounted with an extension  1102  so as to pivotally mouth to the tube body  12 . The tube body  12  is an extension from the tube opening  11  and has a larger diameter to hold a liquid  20 . The dropper  10  has a head end  13  is a ball-like body at the rear end of the tube body, and has a wall  1301  thickness thinner than the tube body. The tube opening  11 , the tube body  12  and the head end  13  are formed as one unit, and the dropper  10  is filled with a liquid  20  (the head end  13  is provided with air) and is the tube opening  11  is sealed.  
       FIG. 3A  is a first preferred embodiment of the present invention. Before a liquid  20  is filled into the tube opening  11  of the dropper  10 , an appropriate amount of the liquid  20  is injected via the tube opening  11 . As shown in  FIG. 3B , a foil  14  is glued at the mouth section  1101  of the tube opening  11 . Then the mouth section  1101  is sealed. When application, the foil  14  is torn off and the atmospheric pressure will prevent liquid  20  from flowing out. When the user presses the head end  13 , the liquid  20  will flow out, and the pressure of the fingers controls the flow of the medicine.  
      Referring to  FIG. 4A , which shows a second preferred embodiment. The tube opening  11  is filled with a liquid  20  via them and a plug  1103  is inserted to the tube opening. The mouth section  1101  of the tube opening  11  is cut circular to form score mark  15 . When the user tears off the score mark  15 , the extension section  1102  will form an opening. Due to the atmospheric pressure, the liquid  20  will not flow out only when the user presses the head end  13 .  
      Referring to  FIG. 5A  showing a third preferred embodiment of the present invention. External threads  1104  are provided externally at the tube opening  11  and the tube opening  11  is filled with a liquid  20 . As shown in  FIG. 5B , a cap  16  with inner threads  1601  is mounted at the external threads of the tube opening  11  such that the cap  16  seals the tube opening. When in application, the cap  16  is unscrewed and the mouth section  1101  becomes an opening. The depression at the head end  13  will cause the liquid  20  to flow out.  
       FIG. 6A  shows a forth preferred embodiment. Before a liquid  20  is filled into the tube opening  11 , as shown in  FIG. 6B , a plug  17  of the protruded cross-section is inserted to the tube opening  11  and the plug seals the tube opening  11 . When in application, the plug  17  is unplugged and the mouth section  1101  becomes an opening. At this instance, the atmospheric pressure prevents the liquid  20  of the dropper  10  from flowing out. When the user depresses the head end  13 , the liquid  20  will flow out. The depression force controls the flow rate and amount of the liquid  20 .  
      It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.  
      While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
