Tank structure of filled spray can

The present invention relates to a container for storing materials, and more particularly to a can body structure of a filled spray can which can reduce the manufacturing cost while taking into consideration the safety of use.

The spray can is a common product for spraying contents of oil or solvent out of the can body by using a pressurized fluid. In order to increase the rigidity of the can body of the spray can to withstand the pressure of the pressurized fluid, the tank system of the conventional spray can is made of metal. The material is made in one piece; however, when the oil in the spray can is exhausted, the integrally formed can body needs special tools to fill the contents, which increases the inconvenience when filling the contents.

In order to improve the inconvenience of the conventional spray can filling oil, the existing spray can includes an upper casing and a lower casing, the lower casing being detachably coupled to the upper casing, and the contents contained in the spray can When the user is used, the user can separate the upper casing and the lower casing, and directly fill the contents into the lower casing, and then re-engage the upper casing and the lower casing, and finally use the air compressor. Fill with pressurized fluid.

However, in order to withstand the pressure of the pressurized fluid, the upper and lower casings of the existing spray can are still made of a metal material, and therefore, the existing spray can has the problems of high material cost and costly processing; and, in order to reinforce the distinction For the rigidity of the upper spray can of the upper casing and the lower casing, it is even necessary to increase the thickness of the upper casing and the lower casing, thereby increasing the expenditure of material costs; thus, it is known that the structure of the existing spray can is There is room for improvement and progress.

In order to solve the existing spray cans made of metal, it has a problem of high manufacturing cost. The present invention provides a can body structure of a filled spray can, wherein the first casing and the second casing are made of plastic The material is molded and the metal casing is sleeved on the second casing to increase the strength of the joint between the first casing and the second casing, thereby achieving the purpose of saving production cost while taking into consideration the safety of use. .

The present invention solves the technical problem of the can body structure of the filled spray can, comprising: a first housing, which is a plastic member, the first housing has an outer peripheral surface and an opposite first end and a a second end, the first housing includes an assembly portion and a ring abutting portion, the assembly portion is located at a first end of the first housing, and the ring abutting portion is disposed on an outer peripheral surface of the first housing, the ring The abutting portion abuts the assembly portion and is adjacent to the first end of the first housing; a second housing is a plastic member coupled to the first housing; and a bundle of rings, which is a metal member, The collar sleeve is fixed to the second housing and adjacent to the junction of the first housing and the second housing, and the second housing and the collar are abutted against the ring abutting portion.

The can body structure of the filled spray can, wherein the second casing comprises a joint portion, and the joint portion of the second casing is screwed to the assembly portion of the first casing.

The can body structure of the filled spray can, wherein the second casing has an outer peripheral surface, an opposite first end and a second end, and the second casing comprises at least one click convex a ring, the second housing is located at the second end of the second housing, the at least one latching ring is disposed on the outer peripheral surface of the second housing and adjacent to the second end of the second housing; The bundle ring has an inner circumferential surface and includes at least one click ring groove, at least one click ring groove of the bundle ring is disposed on an inner circumferential surface of the bundle ring, and at least one click ring groove of the bundle ring Engaged with at least one of the latching collars of the second housing.

The can body structure of the filled spray can, wherein at least one click ring of the second casing is set to two, and at least one click ring groove of the bundle ring corresponds to the two snap rings And set to two.

The can body structure of the filled spray can, wherein the bundle ring is fixedly fixed to the second casing when the second casing is molded.

The enhancements achieved by the technical means of this creation are:

1. The filled spray can of the present invention is formed by plastic molding of the first casing and the second casing, thereby reducing the material cost and eliminating the processing cost, so that the creation can reduce the cost of the spray can. a purpose; in addition, the metal collar is close to the joint of the first housing and the second housing, and the strength of the joint between the first housing and the second housing can be strengthened, and the first housing made of plastic is The junction of the second housing can withstand the pressure of the pressurized gas, making the creation safer in use.

2. The first casing and the second casing of the present invention are made of plastic and can transmit light, and the user can observe the residual amount of the contents inside the creation through the first casing and the second casing, and the metal is made of metal. Compared with the existing spray cans, the first and second casings of the plastics of the present invention can solve the problem that the existing spray cans of the metal can not detect the residual content of the contents therein, and the convenience of the use of the creation is increased. Sex.

3. This creation combines plastic and metal materials in the production of materials. Plastic and metal materials can not only make up for each other's deficiencies in material properties, but also give the user a harmonious feeling of different materials in the design. Compared with the existing spray cans made of metal, this creation is more flexible in appearance and more beautiful.
