Abstract

A spray can has a first body, a second body, and a reinforcing sleeve. The first body is made of plastic. The second body is made of plastic and is connected to the first body. The reinforcing sleeve is made of metal. The reinforcing sleeve is sleeved on the second body and is adjacent to a joining portion where the second body is connected to the first body. The first body and the second body made of plastic save a lot of material and machining expenses. The reinforcing sleeve8 ade of metal enhances the rigidity of the joining portion of the first body and. the second body.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to a container structure of a spray can that may be manufactured at a reduced manufacturing cost.2. Description of Related Art[0002]A spray can is a container filled with compressed fluid and content such as paint, oil, or hair styling products. For improving rigidity of the spray can, a traditional spray can is integrally made of metal. Since the traditional spray can is a metallic integral structure, it is able to sustain pressure caused by the compressed fluid. However, the traditional spray can of an integral structure can be refilled only by specialized tools. Therefore, the traditional spray can is inconvenient for refilling.[0003]In order to mitigate a problem that the traditional spray can is inconvenient for refilling, a conventional spray can with two detachable bodies has been invented. The conventional spray can has an upper body and a lower body. The lower body is detachably connecte...
