Description

AEROSOL SPRAY PAINT CAN AND ITS INNER SLEEVE FIELD OF THE TECHNOLOGY The present utility model relates to aerosol spray paint cans, and particularly to an aerosol spray paint can and its inner sleeve. BACKGROUND Aerosol spray paint cans are commonly used in spraying operations. Since operation of aerosol spray paint cans is rather fast and convenient, they have been widely used. Nowadays, there is usually only a single component of paint inside an aerosol spray paint can. Therefore, it can be used for many times and for a long period of time, and the paint inside the paint spray can will not become solidified. For some spraying operations, it is usually required to mix one type of paint with other reagent or other component of paint before spraying. After mixing, the paint has to be sprayed out immediately; otherwise, the paint will become solidified if the time of reaction is a little bit long, and there is no way to store the mixed paint. In these circumstances, it is not possible to use aerosol spray paint cans. Therefore, spraying operation requires preparation of paint on the spot and is rather troublesome. SUMMARY OF THE UTILITY MODEL An object of the present utility model is to overcome the above-mentioned defects of the existing products and provide an aerosol spray paint can and its inner sleeve. The technical solution of the present utility model to realize its objective is an inner sleeve provided in an aerosol spray paint can. The inner sleeve includes a sleeve body and a sleeve cover both having an outturned flange. A sealing seat is provided on an inner side of the cover. A mandrel is sealingly inserted through the sealing seat, and an outer end portion of the mandrel is sealingly protruded through the cover. The sleeve body is provided with a detachable unit adapted to be separable therefrom, and an inner end portion of the mandrel is in contact with the detachable unit of the sleeve body. 1 The sleeve body is provided with an annular notch. The portion of the sleeve body below the annular notch is the detachable unit, and the inner end portion of the mandrel is in contact with a bottom portion of the sleeve body. The sleeve body includes an upper portion and a lower portion nestably coupled thereto. A coupling portion of the lower portion includes a sealing groove and a sealing ring, and the inner end portion of the mandrel is in contact with the lower portion of the sleeve body. The inner end portion of the mandrel is provided with a push plate, and a plurality of fluid flow holes are formed on the push plate. The periphery of a main body of the mandrel is in the form of a cross-shaped blade. The outermost diameter of the cross-shaped blade is equal to the inner diameter of the sleeve body. A convex ring is formed on the mandrel at the inner side of the cover. An annular seal is mounted between an upper side of the convex ring and the cover, and a spring is provided between a lower side of the convex ring and the sealing seat. At the same time, the present utility model also provides an aerosol spray paint can having a paint spray can body and a nozzle provided at one end thereof. The aerosol spray paint can includes an inner sleeve provided at the other end of the paint spray can body. The inner sleeve includes a sleeve body and a sleeve cover both having an outturned flange sealingly coupled with the paint spray can body. A sealing seat is provided on an inner side of the cover. A mandrel sealingly is inserted through the sealing seat, and an outer end portion of the mandrel sealingly is protruded through the cover. The sleeve body is provided with a detachable unit adapted to be separable therefrom, and an inner end portion of the mandrel is in contact with the detachable unit of the sleeve body. The sleeve body is provided with an annular notch. The portion of the sleeve body below the annular notch is the detachable unit, and the inner end portion of the mandrel is in contact with a bottom portion of the sleeve body. 2 The sleeve body includes an upper portion and a lower portion nestably coupled thereto.

DESCRIPTION OF THE DRAWINGS FIGS. 1, 2, 3, 4 and 5 are illustrative diagrams of the structure of five embodiments of the inner sleeve of the aerosol spray paint can of the present utility model respectively. FIG. 6 is an illustrative diagram of the structure of the mandrel according to another embodiment of the utility model. 3 FIG. 7 is an illustrative diagram of the structure of the aerosol spray paint can according to an embodiment of the present utility model. DETAILED DESCRIPTION OF EMBODIMENTS The present utility model is further described by the below detailed description of the embodiments and the accompanying drawings. As shown in FIGS. 1-5, an inner sleeve of an aerosol spray paint can of the present utility model is disclosed. The inner sleeve is used to store a fluid for the preparation of paint or other spray material. When in use, the fluid inside the inner sleeve can be mixed with the fluid inside a body of the aerosol spray paint can to produce the necessary spray material. The inner sleeve includes a sleeve body 1 and a sleeve cover 2 both having an outturned flange 200. A sealing seat 3 is provided on an inner side of the sleeve cover 2. The sealing seat 3 and the sleeve cover 2 are sealingly connected. A mandrel 4 is sealingly inserted through the sealing seat 3. The mandrel 4, the sealing seat 3 and the sleeve cover 2 are sealingly connected. Also, an outer end portion of the mandrel 4 is sealingly protruded through the cover 2. The sleeve body 1 is provided with a detachable unit 11 adapted to be separable therefrom (i.e. open the sleeve body). An inner end portion of the mandrel 4 is in contact with the detachable unit 11 of the sleeve body 1. The mandrel 4 can push the detachable unit 11 so as to separate the detachable unit 11 from the sleeve body 1 and turn the sleeve body 1 to an open condition where the paint or reagent inside the inner sleeve can flow out and mix with the paint inside the aerosol spray paint can. Shaking of the paint spray can will produce a paint suitable for carrying out quick spraying operation. Particularly, the sleeve body 1 is provided with an annular notch 101. The portion of the sleeve body 1 below the annular notch 101 is the detachable unit 11. The inner end portion of the mandrel 4 is in contact with a bottom portion of the sleeve body 1. When the mandrel 4 is pushed against the bottom portion of the sleeve body 1, the annular notch 101 will rupture thereby separating the lower portion below the annular 4 notch 101 and opening the sleeve body 1. The fluid inside the inner sleeve will then mix with the fluid outside the inner sleeve. The annular notch 101 may be provided at the middle of the sleeve body 1 (as shown in the embodiment in FIG. 1) or at any position near the top (as shown in the embodiment in FIG. 2). The annular notch 101 can be formed on the inner wall or the outer wall. The annular notch 101 may also be formed on the bottom surface of the sleeve body 1 (as shown in the embodiment in FIG. 3) so long as the lower end portion of the mandrel 4 is in contact with the center of the bottom surface of the sleeve body 1. As shown in FIGS. 4 and 5, the sleeve body 1 may include an upper portion 12 and a lower portion nestably coupled thereto. A coupling portion of the lower portion includes a sealing groove 111 and a sealing ring 112. The inner end portion of the mandrel is in contact with the lower portion of the sleeve body 1. That means the lower portion of the sleeve body 1 is the detachable unit 11. When a pushing force is exerted by the mandrel 4, the upper and lower portions will be separated so that the fluid inside the sleeve body 1 will be mixed with the fluid outside the sleeve body 1. In the embodiment shown in FIG. 5, the inner side of the detachable unit 11 is formed with a projecting platform 113 for making contact with the mandrel 4 so that the length of the mandrel 4 can be shortened. The inner end portion of the mandrel 4 is provided with a push plate 41 and a plurality of fluid flow holes 42 are formed on the push plate 41 for the flowing of fluid therethrough. Since the push plate 41 has a larger area, its contact area with the detachable unit become larger. This makes the pushing force of the mandrel 4 more even and ensures that the detachable unit can be separated. This can prevent incomplete separation of the detachable unit due to uneven pushing force, which will affect the speed and evenness of the mixing of fluids. The purpose of the fluid flow holes 42 is to allow the fluid inside the sleeve body 1 to flow out and mix with the fluid outside much faster and better. A convex ring 43 is formed on the mandrel 4 at the inner side of the cover 2. An annular seal 44 is mounted between an upper side of the convex ring 43 and the cover 2. A spring 45 is provided between a lower side of the convex ring 43 and the sealing seat 3. Sealing is achieved by the annular seal 44, the sealing seat 3 and the cover 2. 5 The spring 45 is in a compressed state and exerts a spring force to push the mandrel 4 outwards. The mandrel 4 needs to overcome the spring force as well as the coupling force coupling the detachable unit 11 and the sleeve body 1 in order to separate the detachable unit 11 from the sleeve body 1. This prevents the mandrel 4 from being pushed easily and opening the inner sleeve unintentionally. As shown in FIG. 6, the periphery of the main body of the mandrel 4 may be in the form of a "cross-shaped blade". The outermost diameter of the "cross-shaped blade" is equal to the inner diameter of the sleeve body 1. Four contact points at the bottom of the mandrel 4 are in contact with the bottom portion of the sleeve body 1. The periphery of the main body of the mandrel 4 is in contact with the sleeve body 1 to facilitate the positioning of the mandrel 4. Also, after the "cross-shaped blade" of the mandrel 4 pushes open the lower portion of the sleeve body 1, a much wider space is provided for carrying out the mixing of the two groups of component. The mandrel shown in FIG. 6 can replace the mandrel shown in FIGS. 1-5. As shown in FIG. 7, the present utility model also provide an aerosol spray paint can having a paint spray can body 5 and a nozzle 51 provided at one end thereof. The aerosol spray paint can also includes an inner sleeve 100 mounted at the other end of the paint spray can body 5. The inner sleeve 100 can be any one of the inner sleeves shown in FIGS. 1-5. The inner sleeve in FIG. 7 is the inner sleeve shown in FIG. 1. The spray operation of the aerosol spray paint can has been described in the spray operation of the above-mentioned inner sleeve and will not be repeated here. The present utility model is based on an existing aerosol spray paint can, and an inner sleeve is sealingly installed at a bottom opening of the aerosol spray paint can. The inner sleeve is sealingly provided with a protruding mandrel. The inner sleeve may be filled with another kind of fluid or powder. When in use, a user first pushes the mandrel with force so that it pushes open the detachable unit of the inner sleeve and opens the inner sleeve. The fluid or powder inside the inner sleeve and the fluid inside the paint spray can body can mix and react. Shaking of the paint spray can produces a paint suitable for carrying out quick spraying operation. 6 The present utility model put two kinds of component material in the same paint spray can. When not in use, the two kinds of component are in a separate condition. They will not react and can be stored for a long period of time. When spraying is needed, then the inner sleeve can be pushed opened by the mandrel and the necessary mixed components can then be produced by mixing. Therefore, the present utility model makes spraying operations much more convenient and increases the spraying efficiency. 7
