Document Type and Number:
Japanese Patent JP2023154285
Kind Code:
A
Abstract:
To provide a liquid injection device capable of not only filling liquid easily but also improving durability of a closed container compared to conventional container.SOLUTION: A liquid injection device 1 comprises: an injection needle 10 for injecting liquid into a closed container; an outer cylindrical body 20 arranged so as to cover the injection needle 10 from the outside thereof; and a pedestal part 30 to which the injection needle 10 and the outer cylindrical body 20 are attached. The pedestal part 30 is formed with a groove part 37 for causing air to flow to the outside of the pedestal part 30 from a prescribed part attached with the outer cylindrical body 20. The outer cylindrical body 20 is formed with an opening 21 for causing air passing through a gap between the outer cylindrical body 20 and the injection needle 10 to flow to a groove part 37. When a liquid is injected into the closed container using the injection needle 10, air in the closed container flows to the outside through a lower end of the outer cylindrical body 20, the gap between the outer cylindrical body 20 and the injection needle 10, the opening 21 and the groove part 37.SELECTED DRAWING: Figure 2
