Tool can manufacturing method

The present invention relates to a method of manufacturing a tool can, and more particularly to a method of manufacturing a tool can suitable for storing tools such as a wrench or a screwdriver.

In general, locomotives, bicycles, and other household appliances, in the course of use, sometimes have some problems that need to be solved immediately, and in order to facilitate maintenance at any time, users usually use common maintenance tools and parts, such as wrenches. , screwdrivers, screws, nuts, etc., put into a tool can, so that you can use it at any time, in case you need it.

A variety of tool cans have appeared on the market, one of which contains two left and right housings made of plastic material and a zipper connecting the circumferences of the housings. The housing and the zipper cooperate to define a containment space for receiving the tool. In use, the loading space can be opened or closed by pulling the zipper. The following is mainly explained for the manufacturing method of the tool can.

Referring to Figures 1 and 2, a prior art tool can manufacturing method includes an injection molding step 11 and a zipper connection step 12. In the injection molding step 11, two housings 14 are formed by injection molding from one injection molding machine 13. The zipper connection step 12 is to bond a zipper 15 between the circumferences of the housings 14. As can be seen from the above, in the injection molding step 11, the injection molding machine 13 must be injection molded twice to form the two casings 14, and the present invention provides another manufacturing method for the consumer to choose.

Accordingly, it is an object of the present invention to provide a method of manufacturing a tool can that is innovative in the art.

Thus, the method of manufacturing the tool can of the present invention comprises: a hollow molding step, and a cutting half step. The hollow forming step is blow molding to form a hollow can body having an outer surface and a cutting groove longitudinally surrounding the outer surface. The cutting half step is cutting along the cutting groove to divide the can body into two left and right corresponding housings.

Referring to Figures 3 and 4, a tool can 2 made by an embodiment of the manufacturing method of the tool can 2 of the present invention can be used for tools such as a wrench, a screwdriver, a screw, a nut, a pumping needle or a spare part of a vehicle. (not shown) accommodating, and comprising two housings 21 correspondingly made of thermoplastic plastic material, a lining 22 disposed in the housings 21, and one connecting the housings 21 and capable of A zipper 23 that is opened or closed. The lining 22 has two linings 221 which are respectively adhered to the inner side of the casings 21 to have crashworthiness, and two slats are connected to the linings 221 to facilitate the positioning and positioning of the tools. 222. Of course, the number of such pockets 222 can also be increased or decreased, and even the settings can be omitted, and will not be described here. In the present embodiment, the tool pot 2 has a hollow cylindrical shape. Of course, the shape of the tool pot 2 may be changed, for example, a hollow elliptical cylinder shape, a hollow rectangular column shape, a hollow polygonal column shape, or the like. In use, the tool can 2 can be correspondingly mounted to a bottle cage of a bicycle or a backpack of a rider, and will not be described here.

Referring to FIG. 4, FIG. 5 and FIG. 6A to FIG. 6C, an embodiment of the manufacturing method of the tool can 2 of the present invention comprises a hollow molding step 3, a cutting half step 4, a liner bonding step 5, and a zipper. Connect to step 6.

In the hollow molding step 3, the thermoplastic plastic is extruded into a tube 24 in a high temperature softened state by an extrusion molding machine (not shown), and one end of the tube 24 is first crimped and sealed, and then as shown in FIG. 6A. As shown, a hollow molding machine is driven to be clamped around the outer periphery of the tube 24 by means of two opposing mating molds 31, and the other end of the tube 24 is contracted into a mouthpiece 241 while extending through a gas nozzle 32. The mouthpiece 241 is blown into the pipe 24, and the pipe 24 is inflated to be in close contact with the inside of the mold 31. The mouthpiece 241 is closed and cut and cut out, and the mold 31 is opened and taken off after being cooled. The mold, i.e., can form a hollow can 25 having an outer surface 251 and a cutting groove 252 that longitudinally surrounds the outer surface 251.

The cutting half step 4 is as shown in FIG. 6B, and a blade 41 is wound around the length of the can 25 and cut along the cutting groove 252 to divide the can 25 into the two left and right corresponding portions. Housing 21.

As shown in FIG. 6C, the liner bonding step 5 is to bond the liner 22 to the inside of the casing 21. Next, the zipper connecting step 6 is to sew the zipper 23 between the circumferences of the casings 21 to form the tool can 2. Of course, in the design, the manner of bonding the zipper 23 to the casings 21 can also adopt other fixing methods, for example, using a thermocompression bonding technique, and in addition, the connection structure between the casings 21 can also utilize the buckles. The zipper 23 is replaced by a structure such as a fastening tape or a magnet, as long as the tool can 2 can be opened or closed.

In summary, the method of manufacturing the tool can 2 of the present invention is that the can blank 25 having the cutting groove 252 is formed by the hollow molding step 3, and the can blank 25 is along the cutting half step 4 The cutting groove 252 is cut into the casings 21, and then the subsequent steps are performed. Therefore, for the person skilled in the art of manufacturing the tool can 2, the manufacturing method of the innovative tool can 2 is indeed achieved. The purpose of the invention.

However, the above is only the embodiment of the present invention, and the scope of the invention is not limited thereto, and all the equivalent equivalent changes and modifications according to the scope of the patent application and the patent specification of the present invention are still The scope of the invention is covered.
