A dispensing container according to the invention includes a container body having a rod-like shape. The dispensing container is therefore compact and the user can hold the dispensing container as if the user holds a pen and use the thumb, the index finger, and any other finger to apply pressure to the dispensing container so as to dispense a drug solution. A heat insulating grip is attached to the outer circumferential surface of the container body, whereby heat originating from the body temperature of a finger of the user will not be transferred to the drug solution or volatilize it. No excessive dispensing that is not intended by the user will therefore occur. Since the container body is thin and hence unlikely crashed, the user can make adjustment of the pressure applied by the thumb, the index finger, and any other finger to readily extract a single droplet.

1. A dispensing container for dispensing a drug solution contained within the dispensing container, the dispensing container not structured to thread into another container, the dispensing container comprising: a rod-shaped container body formed of a smaller-diameter portion having a discharge port
1. A dispensing container for dispensing a drug solution contained within the dispensing container, the dispensing container not structured to thread into another container, the dispensing container comprising: a rod-shaped container body formed of a smaller-diameter portion having a discharge port that is an open end and a larger-diameter portion having a block end;a nozzle that extends from the discharge port outward in an axial direction of the container body; anda grip made of a heat insulating material and covering an outer circumferential surface of the smaller-diameter portion of the container body;wherein an edge of the grip is in contact with a stepped portion where the smaller-diameter portion and the larger-diameter portion are connected to each other;wherein an outer diameter (D1) of the smaller-diameter portion of the container body ranges from 8 to 13 mm;wherein the wall thickness of the smaller-diameter portion of the container body ranges from 0.3 to 0.9 mm;wherein the grip is formed to have a wall thickness of at least 2 mm;when the outer diameter (D1) and the wall thickness of the smaller-diameter portion of the container body fall within the range claimed above, the grip is formed to have the wall thickness claimed above, a user holds the grip like holding a pen, and the user applies pressure to the smaller-diameter portion through the grip with a thumb, an index finger, and any other finger, the smaller-diameter portion then deforms, whereby a single droplet of the drug solution is dispensed;wherein a length (Lt) of the dispensing container is the sum of a length (L) of the grip and a length (Lc) of the larger-diameter portion;wherein the length (Lt) of the dispensing container ranges from 100 to 200 mm;wherein the length (L) of the grip is at least 50 mm;wherein the length (Lc) of the larger-diameter portion ranges from 5 to 10 mm;when the user holds the grip like holding the pen, and the user holds the grip with the thumb, the index finger, and any other finger, thereby no finger directly contacts the rod-shaped container body formed of the smaller-diameter portion, with the grip having a heat insulating capability which thereby prevents heat originating from a temperature of the fingers from being transferred to the rod-shaped container body formed of the smaller-diameter portion; andwhen the user holds the grip like holding the pen, and the user holds the grip with the thumb, the index finger, and any other finger, whereby an amount of heat radiated from the fingers and a back of the hand of the user to the larger-diameter portion is very small, and the radiated heat will not reach a gas accumulated in an upper end portion of the larger-diameter portion, as a result, a change in a temperature of the content in the dispensing container can be minimized, when the user uses the dispensing container, the user can hold and squeeze the grip to dispense a single droplet, and no unintended excessive dispensing of the drug solution will occur. 2. The dispensing container according to claim 1, wherein a ratio of a length (Lt) of a portion of the dispensing container except the nozzle to an outer diameter (D2) of the larger-diameter portion of the container body is defined as an aspect ratio, and the aspect ratio (Lt/D2) ranges from 5 to 22. 3. The dispensing container according to claim 1, wherein an outer diameter (D2) of the larger-diameter portion ranges from 9 to 18 mm. 4. The dispensing container according to claim 1, wherein the cross-sectional shape of the larger-diameter portion of the container body taken along a plane passing through a central axis of the container body is a rectangle, a semicircle, a semiellipse, a polygonal shape, or a curved shape. 5. The dispensing container according to claim 1, wherein at least part of the circumference of the smaller-diameter portion forms the stepped portion. 6. The dispensing container according to claim 1, wherein the cross-sectional shape of the larger-diameter portion taken along a plane perpendicular to the central axis of the container body is similar to that of the smaller-diameter portion. 7. The dispensing container according to claim 1, wherein the cross-sectional shape of the larger-diameter portion taken along a plane perpendicular to a central axis of the container body is not similar to that of the smaller-diameter portion. 8. The dispensing container according to claim 1, wherein the grip is made of an elastomer. 9. The dispensing container according to claim 1, wherein the surface of the grip undergoes a non-slip treatment.
