In a conventional injection adapter, the upper opening of the cylindrical body is sealed with a top wall, and a tongue piece is formed on the top wall by a slit to form an operation piece, so that the entire adapter can be molded integrally. There is what can be done (for example, refer to Patent Document 1).
JP 2001-97466 A

  Such a conventional injection adapter is effective in terms of cost and productivity because the number of parts is reduced. However, a ceiling wall for forming the operation piece is essential, and the operation piece can be easily pushed down. Therefore, since it is necessary to incline the top wall, there is a limit to downsizing. For this reason, when transportation, storage, etc. are taken into consideration, there is room for improvement in terms of flowability due to the bulkiness of the injection adapter.

  An object of the present invention is to provide an injection adapter for an aerosol container that is effective in terms of flowability without increasing the number of parts.

  The injection container for an aerosol container according to the present invention includes two side wall parts erected on an adapter pedestal part mounted on a winding part of the aerosol container, and a beam part spanned between the side wall parts, An operating piece that hangs down between the two side walls from the beam is integrally provided, and a thin portion is formed between the beam and the operating piece, and the operating piece is caused by using the thin portion as a base point. It is characterized by being made possible.

  In addition, another aerosol container injection adapter according to the present invention is connected to two side wall portions erected from an adapter pedestal portion mounted on the winding portion of the aerosol container, and the rear ends of these side wall portions, An operation piece hanging down from the connection portion is provided integrally, and a thin portion is formed between the side wall portion and the operation piece, respectively, and the operation piece can be caused to start from the thin portion. To do.
