Description
- The present invention relates to a container structure of a spray can that may be manufactured at a reduced manufacturing cost.
- 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.
- 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 connected to the upper body of the conventional spray can. When the conventional spray can runs out of content therein, the upper body and the lower body are detachable from each other for refilling in the steps as follows. First refill the lower body Then, rejoin the lower body and the upper body. Finally, refill the conventional spray can with compressed fluid by a pneumatic compressor.
- The conventional spray can is able to sustain the pressure caused by the compressed fluid; nevertheless the lower body and the upper body are still made of metal. The conventional spray can has problems of high manufacturing and machining expenses. On the other hand, in order to enhance rigidity of the lower body and the upper body of the conventional spray can, thickness of the lower body and the upper body of the conventional spray can has to be increased, which further increases expense of material for manufacturing.
- To overcome the shortcomings of the conventional spray can, the present invention provides a spray can to mitigate or obviate the aforementioned problems.
- The main objective of the present invention is to provide a spray can that is able to reduce manufacturing expense on the premise of maintaining rigidity of the spray can.
- The spray can comprises 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 sleeve made of metal enhances the rigidity of the joining portion of the first body and the second body.
- Other objects, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
