Abstract

An application container includes a main body that holds an application material, a cap, and a weakened portion that connects the cap to an outer peripheral surface of the main body. The main body has a tubular shape that extends in an axial direction and forms an opening to expose the application material. The cap overlaps the opening of the main body in the axial direction. The weakened portion is oriented substantially in a circumferential direction of the main body, at a position that is located away from the opening in the axial direction of the main body, and is configured to be split in response to an external force, so as to separate the cap from the main body.

First claim

The invention claimed is:

1. An application container comprising:
a main body that holds an application material, wherein the main body has a tubular shape extending in an axial direction and forming an opening to expose the application material, wherein an outer peripheral surface of the main body includes a recess that extends in a circumferential direction of the main body, and a step portion located adjacent the recess, wherein the outer peripheral surface has a greater diameter at the step portion than at the recess, and wherein the recess is offset from the opening in the axial direction and located between the opening and the step portion;
a cap having a tubular portion that overlaps the opening of the main body in the axial direction; and
a weakened portion that is formed between the tubular portion of the cap and the outer peripheral surface of the main body so that the weakened portion is arranged substantially in the circumferential direction of the main body, wherein the weakened portion is formed in the recess of the main body so that the weakened portion is located away from the opening in the axial direction of the main body, and wherein the weakened portion is configured to be split in response to an external force, so as to separate the cap including the tubular portion, from the main body including the opening that exposes the application material with the cap removed.

2. The application container according to claim 1 ,
wherein the cap includes a wing portion protruding from the tubular portion in a direction intersecting an axial direction of the tubular portion.

3. The application container according to claim 2 ,
wherein the wing portion includes an information display portion displaying information regarding the application material.

4. The application container according to claim 1 ,
wherein the weakened portion includes a plurality of connection portions arranged in the circumferential direction, that connect the tubular portion of the cap with the main body, and a plurality of gaps arranged in the circumferential direction between adjacent pairs of the connection portions so as to separate the cap from the main body in response to a rotation of the cap relative to the main body.
