Problems solved by technology
[0003] At present, the screw-top packaging jars used in the market are generally made of plastic. This kind of plastic screw-top packaging jars has the following disadvantages: poor light-shielding performance, unable to adapt to the filling inside; and the product grade of plastic screw-top packaging jars is low , low added value
For this reason, people begin to use aluminum screw-top packaging cans, but the screw openings of existing aluminum quality screw-top packaging cans are directly rolled by a thread rolling device. Such a structure has the following disadvantages: first, in the packaging cans The inner wall of the neck forms an internal thread, and only a threaded can lid can be used to seal the cap, instead of using a cork or the like in the mouth of the can to seal, and the sealing performance is limited; secondly, because the inner wall of the packaging can neck has an internal thread, the solution is easily adsorbed on At the inner thread, the solution adsorbed on the inner thread after packaging is easy to deteriorate and become moldy, which affects the packaging and storage effect

Embodiment Construction
[0030] A further detailed description will be made below in conjunction with the accompanying drawings and embodiments of the present invention:
[0031] As shown in the figure, an aluminum screw-top packaging can includes a can barrel 11, a can bottom 12, a can shoulder 13, a can neck 14 with a smooth inner wall and a can mouth 15, and the can barrel 11, can bottom 12, can shoulder 13 and can neck 14 is an integral molding, and a sleeve sleeve 3 with external thread is tightly sleeved outside the tank neck 14. In the present invention, the sleeve 3 is a plastic sleeve, and the number of external threads on the sleeve 3 is not more than 5, and the sleeve 3 is used to closely connect with a tank cover with an internal thread.
[0032] Wherein, the upper edge of the bottom 12 of the tank extends upwards to be the tank 11, the tank 11 is a hollow cylinder, the tank 11 shrinks upwards to form a tank shoulder 13 and a tank neck 14, and then the sleeve 3 is put into the tank neck 14...

The invention discloses an aluminum screw socket packaging can and a production method thereof. The design key points of the production method are that the production method comprises the following steps: firstly, a lubricant is added into an aluminum sheet, uniformly mixed with the aluminum sheet and extruded into a coarse can blank; secondly, an opening end of the coarse can blank is cut into the length required, dirt inside and outside the coarse can blank is cleaned, and the opening position of the coarse can blank is retracted into can shoulders and a can neck; and thirdly, a cylinder sleeve provided with external threads is sleeved on the outside of the can neck, the opening on the upper end of the coarse can blank is flanged to form a can opening with lips, the can opening is flanged and presses the upper end of the cylinder sleeve, and the lower end of the cylinder sleeve leans against the can shoulders. The invention aims to provide the aluminum screw socket packaging can with beautiful appearance, good light-shielding and sealing properties, high added value and high grade, and simultaneously provides the production method for the aluminum screw socket packaging can withsimple processing method and high automation degree.
Description
[technical field] [0001] The invention relates to an aluminum screw packaging can and a production method. [Background technique] [0002] Screw-top packaging can is a packaging container widely used in various industries, and can be used to hold beverages, wine, etc. The screw-top packaging jar is easy to operate, safe and reliable, and is deeply loved by users. [0003] At present, the screw-top packaging jars used in the market are generally made of plastic. This kind of plastic screw-top packaging jars has the following disadvantages: poor light-shielding performance, unable to adapt to the filling inside; and the product grade of plastic screw-top packaging jars is low , low added value. For this reason, people begin to use aluminum screw-top packaging cans, but the screw openings of existing aluminum quality screw-top packaging cans are directly rolled by a thread rolling device. Such a structure has the following disadvantages: first, in the packaging cans The inne...
