Liquid disposable plastic container

Abstract

A plastic vial having a fill port with a structure that is easily collapsible, is sealable in less time, and that minimizes the residual stresses in the vial after it has been filled and sealed. The structure of the fill port includes a proximal end, with respect to the body of the vial, and a distal end, also with respect to the body of the vial. The proximal end is selected from the group consisting of a diamond-shaped end, an elliptical end and a circular end. Additionally, the vial has dispensing openings that minimize the effects of distorting a dispensing end of the vial when the vial is opened.

1 . A container comprising 
 a body defining a cavity, the body comprising 
 a dispensing end  12 ; and  
 a filling end  14  having a hollow fill port  16 , the hollow fill port comprising 
 a circular end  20  proximal to the body; and  
 an elliptical end  18  distal to the body.  
 
   
     
     
         2 . The container of  claim 1  wherein the dispensing end further comprises 
 a hollow neck  24  in hydraulic communication with the cavity at a proximal end of the hollow neck with respect to the body; and  
 a tip at a distal end of the hollow neck with respect to the body, the tip comprising a bulb  28  defining a cavity in hydraulic communication with the hollow neck.  
 
     
     
         3 . The container of  claim 2  further comprising a relatively flat area  32  surrounding the bulb.  
     
     
         4 . The container of  claim 2  further comprising 
 an edge  34  defining a perimeter of the relatively flat area.  
 
     
     
         5 . The container of  claim 2  wherein the bulb and the neck define a shear edge.  
     
     
         6 . The container of  claim 5  wherein the shear edge is serrated.  
     
     
         7 . The container of  claim 2  wherein the tip comprises 
 two bulbs located adjacent to each other, each bulb defining a cavity in hydraulic communication with the hollow neck; and  
 a shear edge defined by an area between the two bulbs.  
 
     
     
         8 . The container of  claim 1  wherein the elliptical end  18  defines an opening suitable for use in filling the body with a product.  
     
     
         9 . The container of  claim 1  wherein the circular end  20  flares out in a generally lateral direction to create the elliptical end  18 .  
     
     
         10 . The container of  claim 1  wherein the elliptical end tapers down to the circular end.  
     
     
         11 . A container comprising 
 a body defining a cavity, the body comprising 
 a dispensing end; and  
 a filling end having a hollow fill port, the hollow fill port comprising a proximal end with respect to the body and a distal end with respect to the body, wherein the proximal end is selected from the group consisting of an elliptical end, a circular end and a diamond-shaped end, and wherein the distal end is selected from the group consisting of a diamond-shaped end and an elliptical end.  
   
     
     
         12 . The container of  claim 11  wherein the dispensing end further comprises 
 a hollow neck in hydraulic communication with the cavity at a proximal end of the hollow neck with respect to the body; and  
 a tip at a distal end of the hollow neck with respect to the body, the tip comprising a bulb defining a cavity in hydraulic communication with the hollow neck.  
 
     
     
         13 . The container of  claim 12  further comprising a relatively flat area  32  surrounding the bulb.  
     
     
         14 . The container of  claim 12  further comprising 
 an edge defining a perimeter of the relatively flat area.  
 
     
     
         15 . The container of  claim 12  wherein the bulb and the neck define a shear edge.  
     
     
         16 . The container of  claim 15  wherein the shear edge is serrated.  
     
     
         17 . The container of  claim 12  wherein the tip comprises 
 two bulbs located adjacent to each other, each bulb defining a cavity in hydraulic communication with the hollow neck; and  
 a shear edge defined by an area between the two bulbs.  
 
     
     
         18 . The container of  claim 11  wherein the distal end defines an opening suitable for use in filling the body with a product.  
     
     
         19 . The container of  claim 11  wherein the distal end tapers down to the proximal end.
