curved outer surface 108 that is opposite the curved inner surface 106 and the bottom wall 104 is curved to provide a fully rounded bottom such that its curved outer surface lacks a planar surface a user recognizes the exemplary dose cup 100 is not intended to be set down on the bottom wall 104 in the embodiment of fig1 c the vertical sidewall 102 is tapered at an angle u03b8 to provide a tapered flange such that the opening 110 of the dose cup 100 has a diameter greater than that of a concave cavity 112 this tapered configuration facilitates the dose cup 100 being placed on a medicine bottle cap and permits the dose cup 100 to fit a variety of different sizes of medicine bottle caps the tapered flange also influences the evacuation of the liquid medication during use additionally the tapered flange also provides added structural strength to the dose cup that permits the vertical sidewall 102 to be substantially thinner than a corresponding dose cup that lacks the tapered flange for example in one embodiment the vertical sidewalls and bottom wall are between 0 1 and 0 5 mm thick this results in a significant reduction of the mass of the dose cups and a corresponding reduction in the amount of plastic that is used the angle u03b8 of the tapered flange may be for example between 5 u00b0 and 20 u00b0 in another embodiment the angle u03b8 is between 5 u00b0 and 10 u00b0 fig2 a and fig2 b are.
