Abstract: A refillable spray container including a container main body and a cap with a nozzle, wherein a tubular mouth piece provided with engaging projections is mounted to a mouth portion of the container main body, and wherein a cap provided with a guide groove that engages with the engaging projections in a bayonet style is attached to the mouth piece in a freely attachable/detachable manner. The cap includes a brim portion for sealing a top surface portion of the mouth piece and a cylindrical portion that is inserted into the interior of the mouth piece, wherein a guide groove is formed on an outer periphery of the cylindrical portion.

Abstract: A refillable spray container comprising a container main body 1 and a cap 2 with a nozzle 2a, wherein a tubular mouth piece 6 provided with engaging projections 6a is mounted to a mouth portion of the container main body 1, and wherein a cap 2 provided with a guide groove that engages with the engaging projections 6a in a bayonet style is attached to the mouth piece 6 in a freely attachable/detachable manner. The cap 2 comprises a brim portion 21 for sealing a top surface portion of the mouth piece 6 and a cylindrical portion 22 that is inserted into the interior of the mouth piece 6, wherein a guide groove 23 is formed on an outer periphery of the cylindrical portion 22. The spray container of the present invention is superior in economical efficiency since the cap 2 may be rotated to easily detach the same from the container main body 1 so that spraying liquid and pressurized gas may be refilled in a safe and simple manner.
