1. Field of the Invention
The present invention relates generally to a barrel, and more particularly to an innovative barrel with an external cylinder and an internal vessel positioned at the top of the external cylinder structure.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98
Currently available barrel products still have some disadvantages, including the barrel structure of a toilet brush assembly. As shown in
First, a metal bottom plate 112 must be assembled at the bottom of metal cylinder 111 of the barrel 11, leading to substantial increase in the cost of the metal materials. Also, the metal cylinder 111 shall be assembled onto the metal bottom plate 112 through a special procedure (e.g. punching or rolling), thus increasing the manufacturing cost along with lowered manufacturing efficiency.
Second, if the inner space formed by the metal cylinder 111 and metal bottom plate 112 of the barrel 11 is used to accommodate the sewage released from the toilet brush 13, corrosion, fracture or damage will occur rapidly. Hence, a cup 12 is arranged into the barrel 11, leading to an increase of material cost. Moreover, since a gap still exists between the cup 12 and metal cylinder 111, residual water on the wall of cup 12 and metal cylinder 111 will possibly bring about corrosion at the joint of the metal bottom plate 112 and metal cylinder 111.
Third, as the cup 12 of typical barrel 11 is used to accommodate the sewage released from the toilet brush 13, it is required to take out the cup 12 manually from the barrel 11 when it is intended to clean up the sewage, leading to inconvenience of operation and difficulty of cleaning because of limited inner space of the barrel 11.
Thus, to overcome the aforementioned problems of the prior art, it would be an advancement in the art to provide an improved structure that can significantly improve efficacy.
Therefore, the inventor has provided the present invention of practicability after deliberate design and evaluation based on years of experience in the production, development and design of related products.
Based on the unique present invention, the top flange of the internal vessel and open top of the external cylinder are positioned together. The bottom of external cylinder is open-ended, such that the metal bottom plate of the barrel can be saved, thus reducing the material cost, manufacturing cost and processing procedure with better industrial efficiency.
As the external cylinder and internal vessel are integrated by metal and plastic materials, the sewage released from toilet brush drips into the plastic vessel, thereby preventing corrosion and extending the life span of products.
Based on the unique top flange of the internal vessel and the open top of the external cylinder being positioned together, the sewage in the barrel can be poured out conveniently, without the need for manually taking out the cup from the barrel.
Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.
The toilet brush assembly A comprises a barrel 20, which has an external cylinder 21 and an internal vessel 22. The external cylinder 21 is made of metal material and comprised of a cylinder body 211, an open top 212 and an open bottom 213. The internal vessel 22 is made of plastic material and comprised of an inner space 221 and a top flange 222. The top flange 222 of internal vessel 22 and open top 212 of external cylinder 21 are positioned together.
A toilet brush 30 comprises a handle 31 and a brush portion 32 at one end of the handle 31. The brush portion 32 can be arranged into the inner space 221 of the internal vessel 22 of the barrel 20. The handle 31 protrudes from the top of the barrel 20.
A cover body 40 is arranged at a preset position of the toilet brush 30 and can be covered onto the open top 212 of external cylinder 21 of the barrel 20, thereby positioning the toilet brush 30 and barrel 20.
The top flange 222 of internal vessel 22 and open top 212 of external cylinder 21 are positioned together in multiple ways.
