Abstract: In a bottle made of synthetic resin of the present invention, a handle is combined to a bottle body so that the bottle can be easily handled for carrying it and pouring the content. When the joint of the handle to the bottle body is unstable, it is difficult to handle the bottle and it will occur an accident when the handle comes off the bottle body. Therefore, in the present invention, a reinforcing structure is provided to necessary portions not to deform the joining portion of the handle to the bottle body and further a coming off-preventing mechanism is provided so that the handle does not comes off the bottle. The coming off-preventing mechanism is accomplished by a supporting projection and/or a supplementary engaging protruding portion and a supplementary engaging recess portion. To ensure the coming off-preventing mechanism, the bottle body is formed by biaxial oriented blow molding with assembly beams of the handle as an insert.

Abstract: A miniature type, rechargeable atomizing spray mechanism having a container for the liquid to be atomized, and further having a cap and axially aligned first and second pressure chambers, one of which depends within a receptacle while the other projects above the cap. A reciprocable spray head or actuator is arranged to cooperate with plural pistons, one each of which are telescopically arranged in said first and second pressure chambers. Upper and lower valve members are available to control the emission of spray of the liquid. The upper valve is maintained closed by a spring element, and the lower valve is opened by reciprocation of the actuator to permit withdrawal of the liquid from the container so that it may pass through a bore provided between the plural pistons and in the pressure chambers and be emitted as a spray from the spray nozzle at the spray head.

Abstract: A container in which a recess for containing a coiled spring is formed at a shaft hole opening in a cover and a container. A connecting portion for connecting the other end of the coiled spring is formed at the other of the cover and the body in such a manner that the connecting portion is substantially oppositely formed to the recess at the shaft hole opening. A connecting piece capable of temporarily connecting the other end of the coiled spring is formed, and a packing elastically contacted with the lower surface of the cover of closed state is associated intimately with the upper end of the bottomed cylindrical container body. Thus, the container can by simply produced by readily associating the cover and the container body and can also assure the sealability between the cover and the body.
