Description

Disposable spray paint can

Technical field

The utility model relates to spray paint can technical field, relates in particular to a kind of disposable spray paint can.

Background technology

At present, common spray paint can all adopts metal can, after being especially finished, inside needs to clean tank body, then refilling paint uses, although this metal can reuse, but clean very trouble, therefore there is now much exempting from the disposable spray paint can of cleaning, for example: Chinese patent Granted publication number: CN202683425U, on January 23 2013 Granted publication day, discloses the disposable spray paint can of a kind of environmental protection, the cover that comprises tank body and match with tank body, described tank body is soft tank body, and tank base is hermetically-sealed construction, does not establish air-vent.Due to tank body softness, under the effect of air pressure, tank body can shrink along with the discharge of painting in tank, uses and does not need to clean, discardable, focuses on, and does not need to use any chemical.Its weak point is that this kind of tank body is soft, if tank body is subject to the flow change that extraneous extruding can cause the nozzle of spray gun when use, thereby it is inhomogeneous to cause spraying paint, and in the time of the spraying of some device interiors, soft tank body is easily punctured and is caused paint leakage.

Utility model content

The utility model, in order to solve the aforementioned problems in the prior, provides a kind of use safer, reliable, can ensure the uniform disposable spray paint can of paint spraying.

To achieve these goals, the utility model adopts following technical scheme:

Disposable spray paint can, comprise spray paint can inner bag, one end of inner bag is connected with lid, the exit of lid is provided with the joint being connected with spray gun, the outside of described spray paint can inner bag is arranged with outer cup, the openend of described outer cup is connected with lid, the bottom of outer cup is provided with air admission hole, the bottom even of described spray paint can inner bag is provided with some through holes, between the described bottom of spray paint can inner bag and the bottom of outer cup, be provided with ventilated membrane, the link of described lid and spray paint can inner bag extends to form connecting ring, and the outer end of connecting ring is provided with screen pack; Described outer cup is made up of light-passing plastic, and described spray paint can inner bag is made up of printing opacity flexible plastic.

Soft spray paint can inner bag is located at outer cup inside, outer cup plays a protective role to spray paint can inner bag, prevent that spray paint can inner bag is subject to external force crimp or is punctured by external object, joint is connected with spray gun, when spray gun work, produce negative pressure, air enters in spray paint can inner bag through ventilated membrane and through hole, thereby the paint of spray paint can inner bag inside is sprayed from spray gun painting nozzle, ventilated membrane can see through air, extraneous dust cannot pass ventilated membrane, prevent that introduced contaminants from entering in spray paint can inner bag and pollute paint, screen pack can prevent that the bulky grain paint particles in paint is sprayed on surface of the work and causes skin of paint out-of-flatness, whole spray paint can is all that light transmissive material is made, just can clearly see surplus and the color of inner paint from the external world, after using, directly lose spray paint can inner bag, then the spray paint can inner bag more renewing uses.

As preferably, the both sides of the described lid formation attachment lug that stretches out, attachment lug is provided with positive stop hook.Attachment lug can be connected with the position-limiting drum on spray gun.

As preferably, the outside of described spray paint can inner bag is provided with some roads annular groove, and the bottom land of described annular groove is curved, and the width of annular groove pushes up gradually and increases from bottom land to groove.In the time that spray gun fast spraying is painted, outside air need to pass ventilated membrane, thereby while causing air supply not enough, self can there is compression in spray paint can inner bag, annular groove is convenient to spray paint can compression, limit to a certain extent and be out of shape from bottom to top compression direction, be conducive to paint spraying simultaneously.

As preferably, on the lateral surface of described connecting ring, be also provided with annular seal groove, the bottom outside of outer cup is provided with seal cover.Annular seal groove has reduced the be connected contact area of lid with annular seal groove, makes connecting ring be divided into two parts, and contact is better like this, and paint is difficult for leaking; If when the paint in spray paint can inner bag does not use, cover seal cover and be convenient to use next time.

Therefore, the utlity model has use safer, reliable, can ensure the uniform beneficial effect of paint spraying.
