Container

Abstract

A container including a container member having a bottom portion and a side wall portion which form a depression, and a lid member configured to adhere to the side wall portion to close an opening of the depression, wherein a projection is provided in an area of the side wall portion to be adhered to the lid member, part of the projection forms an extending portion extending along the lid member as a result of the adhesion, and the extending portion extends toward an inside and an outside and the length in an extending direction of the extending portion extending toward the inside is longer than the length in the extending direction of the extending portion extending toward the outside.

What is claimed is: 
     
         1 . A container comprising:
 a container member including a bottom portion and a side wall portion extending from the bottom portion, and a depression formed in an area surrounded by the bottom portion and the side wall portion; and   a lid member configured to adhere to the side wall portion to close an opening of the depression, wherein   a projection is provided in an area of the side wall portion to be adhered to the lid member, part of the projection forms an extending portion extending along the lid member as a result of the adhesion, and   the extending portion extends toward an inside and an outside where the inside is a side where the opening exists with respect to the projection as a center, and the outside is an opposite side from the inside, and the length in an extending direction of the extending portion extending toward the inside is longer than the length in the extending direction of the extending portion extending toward the outside.   
     
     
         2 . The container according to  claim 1 , wherein the length of the extending portion extending toward the outside is 0.15 mm or shorter. 
     
     
         3 . The container according to  claim 1 , wherein the length of the extending portion extending toward the inside is 0.2 mm or longer. 
     
     
         4 . The container according to  claim 1 , wherein the length of the extending portion extending toward the inside is 1.0 mm or shorter. 
     
     
         5 . The container according to  claim 1 , wherein the thickness of the extending portion extending toward the inside is 0.01 mm or larger. 
     
     
         6 . The container according to  claim 1 , wherein the thickness of the extending portion extending toward the inside is 0.1 mm or smaller. 
     
     
         7 . The container according to  claim 1 , wherein the projection before being subjected to adhesion has an R-shape on the outside thereof. 
     
     
         8 . The container according to  claim 1 , wherein the lid member has a base material and an adhesion layer, and the projection before being subjected to adhesion has a relationship of θ 1 >θ 2  where θ 1  is an angle formed between a straight line which connects a point on the root side, which is one of points inside the projection, and a point on the base material side and the base material and θ 2  is an angle formed between a straight line which connects a point on the root side, which is one of points outside the projection, and a point on the base material side and the base material. 
     
     
         9 . The container according to  claim 1 , wherein the projection before being subjected to adhesion has a shape in which a center of a circumscribing circuit of the projection is arranged on the outside of a center of gravity of the projection. 
     
     
         10 . A container comprising:
 a container member including a bottom portion and a side wall portion extending from the bottom portion, and a depression formed in an area surrounded by the bottom portion and the side wall portion; and   a lid member configured to adhere to the side wall portion to close an opening of the depression, wherein   a projection is provided in an area of the side wall portion to be adhered to the lid member, part of the projection forms an extending portion extending along the lid member as a result of the adhesion, and   the extending portion extends only toward an inside where the inside is a side where the opening exists with respect to the projection as a center, and an outside is an opposite side from the inside.   
     
     
         11 . The container according to  claim 10 , wherein the length of the extending portion extending toward the inside is 0.2 mm or longer. 
     
     
         12 . The container according to  claim 10 , wherein the length of the extending portion extending toward the inside is 1.0 mm or shorter. 
     
     
         13 . The container according to  claim 10 , wherein the thickness of the extending portion extending toward the inside is 0.01 mm or larger. 
     
     
         14 . The container according to  claim 10 , wherein the thickness of the extending portion extending toward the inside is 0.1 mm or smaller. 
     
     
         15 . The container according to  claim 10 , wherein the projection before being subjected to adhesion has an R-shape on the outside thereof. 
     
     
         16 . The container according to  claim 10 , wherein the lid member has a base material and an adhesion layer, and the projection before being subjected to adhesion has a relationship of θ 1 >θ 2  where θ 1  is an angle formed between a straight line which connects a point on the root side, which is one of points inside the projection, and a point on the base material side and the base material and θ 2  is an angle formed between a straight line which connects a point on the root side, which is one of points outside the projection, and a point on the base material side and the base material. 
     
     
         17 . The container according to  claim 10 , wherein the projection before being subjected to adhesion has a shape in which a center of a circumscribing circuit of the projection is arranged on the outside of a center of gravity of the projection.
