Container and method of manufacturing same
There is used a container which includes a first member which serves as a lid portion, a second member which serves as a container portion, and resin with which a flow path, which is formed between the first member and the second member when the first member and the second member come into contact with each other, is filled, the resin bonds the first member and the second member to each other by reaching a filling target position after flowing in from an inflow opening to the flow path, and an opening portion exposed to an exterior of the container is provided at a position where the resin having flowed in from the inflow opening flows out beyond the filling target position in the flow path.
1. A container, comprising:
a first member;
a second member; and
resin filling a flow path that is formed between the first member and the second member when the first member and the second member come into contact with each other, wherein
the resin bonds the first member and the second member to each other by reaching a filling target position after flowing from an inflow opening to the flow path, and
an opening portion is formed in an exterior of the container, the opening portion being provided facing a position where the resin, which has flowed in the flow path from the inflow opening, flows out beyond the filling target position, and
a buffer position which stores the resin having flowed out from the filling target position is provided in the flow path at a position facing the opening portion.
2. The container according to claim 1 , wherein the opening portion is provided such that whether or not the resin has reached the opening portion can be visually recognized from the outside of the container.
3. The container according to claim 1 , wherein the resin flows in from the inflow opening in a state in which the first member and the second member are housed inside a mold, and
the opening portion is covered with an inner wall of the mold when the first member and the second member are housed inside the mold.
4. The container according to claim 1 , wherein the buffer portion is integrated with the opening portion.
5. The container according to claim 1 , comprising a communication flow path that communicates the buffer portion and the opening portion with each other.
6. The container according to claim 1 , comprising an intermediate opening portion exposed to the exterior of the container, the intermediate opening portion being provided at a position between the inflow opening and the filling target position in the flow path.
7. The container according to claim 6 , comprising a plurality of the intermediate opening portions provided in the flow path.
8. A cartridge configured for use in an inkjet recording apparatus, the cartridge comprising:
the container according to claim 1 which stores ink; and
a chip which discharges the ink.
9. The container according to claim 1 , wherein the resin is visible through the opening portion when the opening portion is viewed from outside.
10. The container according to claim 1 , wherein the width of the buffer portion is wider than the width of the flow path.
11. A method of manufacturing a container including a first member and a second member, and having a flow path for resin formed between the first member and the second member when the first member and the second member come into contact with each other, the method comprising the steps of:
forming the flow path by causing the first member and the second member to come into contact with each other inside a mold; and
bonding the first member and the second member to each other by causing the resin to flow in from an inflow opening to the flow path and to reach a filling target position, wherein
an opening portion is formed in an exterior of the container,
the opening portion is provided facing a position where the resin, which has flowed in from the inflow opening in the flow path, flows out beyond the filling target position, and
a buffer portion which stores the resin having flowed out from the filling target position is provided in the flow path at a position facing the opening portion.
12. The method of manufacturing the container according to claim 11 , further comprising a step of inspecting, by image processing, whether or not the resin is visible through the opening portion when the opening portion is viewed from outside.
13. A flow path member, comprising:
a first member,
a second member; and
resin filling a flow path that is formed between the first member and the second member when the first member and the second member come into contact with each other, wherein
the resin bonds the first member and the second member to each other by reaching a filling target position after flowing from an inflow opening to the flow path,
an opening portion is formed in an exterior of the container, the opening portion being provided facing a position where the resin, which has flowed in the flow path from the inflow opening, flows out beyond the filling target position, and,
a buffer portion which stores the resin having flowed out from the filling target position is provided in the flow path at a position facing the opening portion.
