Single dose material and applicator package

Abstract

A single dose material and applicator package that is easily held for removal of a cover and that contains an easily removable applicator. A tray has an applicator well and a material well. Formed in the applicator well is a finger depression adjacent the material well and an applicator support depression adjacent an opposing end of the applicator well. The finger depression permits easy grasping of the tray for removing the cover. The applicator support depression acts as a fulcrum to pivot or lever the applicator out of the tray when a force is applied to one end of the applicator. A material well ramp permits a controlled amount of material to be placed on the applicator brush.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(17) FIGS. 1-10 illustrate a first embodiment of the single dose material and applicator package 10 of the present invention. FIG. 1 is a perspective view illustrating a formed tray 14 with the removal cover 12. The removable cover 12 is removably attached to a surface of the tray 14. The formed tray 14 may be made of any suitable plastic material and preferably vacuum molded, but also may be injection molded. A portion of the cover 12 or a tab may overhang an edge of the tray facilitating removal of the cover. Alternatively, a small portion of the cover 12 may not be attached to the tray 14 facilitating removal. The cover preferably is made of a durable impermeable material, such as a plastic laminated foil. The cover may be adhesively fixed, heat sealed, ultrasonically welded, to the tray 14 or affixed by other equivalent sealing means.

(18) FIGS. 2-10 additionally illustrate the first embodiment of the present invention with the cover removed providing a better view of the features of the present invention. Formed within the tray 14 are several depressions that greatly facilitate the use and function of the single dose material and applicator package 10. Formed within the tray 14 are a flange 16, an applicator well 18, and a material well 20. The flange 16 forms a planar surface above the applicator well 18 and the material well 20. Formed within the material well 20 are a material well bottom 22 and a material well ramp 24. The material well ramp 24 forms an angular surface between the flange 16 and the material well bottom 22. Also formed within the tray 14 in the bottom 32 of the applicator well 18 is a finger depression 26 and a first applicator support depression 28. The applicator support depression 28 is adjacent a rear end 30 of the tray 14. The finger depression 26 forms a first applicator support protrusion on the inside of the applicator well 18. The applicator support depression 28 forms a second applicator support protrusion on the inside of the applicator well 18.

(19) The finger depression 26 and the applicator support depression 28 extend into the applicator well 18. An applicator 34, illustrated in FIGS. 9-10 rests on the surface of the finger depression 16 and the surface of the applicator support depression 28 on the inside of the applicator well 18.

(20) The applicator 34, illustrated in FIGS. 9 and 10, has an applicator handle 36 and an applicator brush 38. The applicator brush 38 may be any type of applicator brush that can hold the material, such as bristles, foam material, or flocking. The finger depression 26 supports a portion of the applicator 34 adjacent the applicator brush 38 and the applicator support depression 28 supports a portion of the applicator 34 adjacent a distal end of the handle 36. A material 40 is placed within the material well 20. The material 40 may be any type of material such as a paste, gel or liquid. Preferably the material 40 is a medicinal material and preferably a dental material. The dental material may be any material used in dentistry such as a cement, sealant, disinfectant, desensitizers, fluoride material, or any other material to be coated on a surface.

(21) One of the advantages of the present invention is illustrated in FIG. 10. As illustrated in FIG. 10, the applicator 34 is easily removed from the applicator well 18 by pressing on the distal end of the applicator handle 36 with a finger. Arrow 42 presents downward pressure applied by a user's finger on the distal end of the applicator handle 36. A wider portion 41, illustrated in FIG. 9, adjacent the rear end 30 of the applicator well 14 has an increased lateral dimension relative to the lateral dimension of a major longitudinal length of the applicator well 18. The wider portion 41 provides sufficient width or lateral dimension for insertion of a user's finger. The lateral dimension of the wider portion 41 should be sufficiently large to accommodate the width of a user's finger. As the user presses on the distal end of the applicator handle 36 of applicator 34 the applicator handle 36 pivots on the applicator support depression 28 acting like a fulcrum to lever upward the applicator handle 36 and the applicator brush 38 so that the applicator 34 may be easily grasped by the user. Therefore, the applicator 34 is easily removed from the applicator well 18 even when the width of the applicator 34 matches closely to the width of the applicator well 18. This reduces the amount of material used in the tray 14 and more securely holds the applicator 34 within the applicator well 18, and yet permits easy removal of the applicator 34 from the applicator well 18.

(22) Once the applicator 34 is removed from the applicator well 18 and tray 14, the applicator brush 38 may be dipped within the material 40 and applied to a surface. To control the amount of material on the applicator brush 38 to be applied to a surface, the applicator brush 38 may be rubbed on the material well ramp 24 so as to remove a desired amount of material 40 therefrom. This provides a means for controlling the amount of material 40 applied to a surface by the applicator brush 38.

(23) FIGS. 11-16 illustrate a second embodiment of a single dose material and applicator package 110 of the present invention. In this embodiment a front applicator channel 146 and a rear applicator channel 148 aid in centering and holding an applicator in the applicator well 118. The handle of an applicator, not shown, is held by the front and rear applicator channels 146 and 148.

(24) In FIGS. 11-16, a removable cover is not illustrated. However it should be appreciated that a removable cover similar to that illustrated in FIG. 1 is placed on the flange 116 in this second embodiment of a single dose material and applicator package 110.

(25) As illustrated in FIGS. 11-16 the single dose material and applicator package 110 comprises a formed tray 114 having a flange 116. Also formed in the tray 114 are an applicator well 118 and a material well 120. The material well 120 has a material well ramp 124 formed therein. The applicator well 118 has a finger depression 126 and an applicator support depression 128 formed in the bottom thereof. The applicator well 118 has a rear end 130 formed therein. Between the rear end 130 and the applicator support depression 128 there is a wider portion 141 having a lateral dimension sufficient for the insertion of a finger of a user.

(26) Formed in the finger depression 126 is a front applicator channel 146 and formed in the applicator support depression is a rear applicator channel 148. The front and rear applicator channels 146 and 148 aid in holding and centering and applicator when the applicator is placed within the applicator well 118. The front and rear applicator channels may extend slightly more than one-hundred and eighty degrees around a handle of an applicator so as to hold securely the applicator within the applicator well 118.

(27) Additionally in this second embodiment, illustrated in FIGS. 11-16, the material well ramp 124 extends from the material well bottom 122 to the flange 116. In this second embodiment the material well ramp 124 can be used as a means to control the amount of material on an applicator brush irrespective of the amount of material placed in the material well 120, as a portion of the material well ramp 124 will extend out of the material. The material well ramp 124 may be textured or ribbed to aid in removing a controlled amount of material from an applicator brush.

(28) The present invention provides an improved single dose material and applicator package that can be more firmly and easily held so the removable cover may be more easily removed. Additionally the applicator support depression acts like a fulcrum so that the applicator may be raised above the flange of the tray for easy removal by only placing a finger adjacent the rear end of the tray.

(29) While the present invention has been described with respect to several different embodiments, it will be obvious that various modifications may be made without departing from the spirit and scope of this invention.
