Therefore, in the easy-to-tear cover in the embodiment, the at least two aluminum foil pull sheets 3 are arranged on the periphery of the aluminum foil cover 2, so that on one hand, the easy-to-tear cover is convenient for consumers with different tearing habits; on the other hand, after aluminium foil lid 2 is torn completely, can need not throw away, utilize metal aluminium foil to have the characteristics of plasticity, can turn up each aluminium foil pulling-on piece 3 is reverse, firm overlap joint is on 4 top edges of can body or on the plastic ring 51 of plastics enclosing cover 5, fine covering jar mouthful, the effect of performance lid, many one protection to prevent that the foreign matter from falling into the jar, and can not destroy the aluminium foil, can realize aluminium foil lid 2's manifold cycles uses repeatedly.

Meanwhile, the shape of the opening in the cover ring 1 is designed to be a regular polygon, each side of the regular polygon forms a scraping edge 13, and the part between each side of the regular polygon and the edge of the inner ring of the cover ring 1 forms a scraping plate, so that the functions of a plurality of scraping plates are realized; on one hand, the problem that the existing milk powder can only have one milk powder scraper and can only scrape milk powder in one position and one direction is solved, a consumer can conveniently scrape milk powder from multiple angles and multiple directions, the milk powder scraper is not limited by left and right hands, the milk powder scraping position angle can be flexibly and freely selected, the milk powder scraper is suitable for people with different weighing habits, and the experience of the consumer is improved; on the other hand, consumers do not need to tear the aluminum foil cover 2 once again to find the powder scraping plate, because the powder amount of the milk powder can which is just opened is full, half of the powder can be torn again, and even the powder can not be torn completely all the time, in a word, the aluminum foil cover 2 can be covered and kept in a good state for a long time as far as possible, the longer the powder is kept, the better the protection of the milk powder is, the best use of the product is realized, and the packaging effect is fully exerted; on the other hand, utilize each scraper blade again, can increase the regional area of heat-seal bonding from a plurality of position, evenly support aluminium foil lid 2, strengthened aluminium foil lid 2 and the involution power of lid circle 1, improved aluminium foil lid 2 greatly and easily collapsed, the fracture problem, prevent that the foreign matter from falling into the jar, play the safeguard effect, be convenient for protect the quality performance of product.

In a particular implementation, the individual aluminium foil tabs 3 are evenly distributed along the circumference of the aluminium foil lid 2.

The number of the specific aluminum foil pull tabs 3 can be determined as required, the more the aluminum foil pull tabs 3 are, the more the aluminum foil covers 2 can be opened at more angles, and the more stable the buckling is when the aluminum foil pull tabs are reversely folded and are lapped on the plastic ring 51 of the can body 4 or the plastic outer cover 5. For example, in the present embodiment, referring to fig. 3, the aluminum foil cover 2 is a circular cover, and the number of the aluminum foil pull tabs 3 is two and is located on two sides of the aluminum foil cover 2 in the same diameter direction; under this mode, each aluminium foil pulling-on piece 3 both can correspond the central point that scrapes limit 13 and put the setting, also can correspond two positions settings of scraping contained angle between the limit 13, as long as two aluminium foil pulling-on pieces 3 just can, more do benefit to and scoop up milk powder under the condition that aluminium foil cover 2 opened minimum amplitude. During actual processing, the correspondence between the positions of the aluminum foil pull sheet 3 and the scraping edge 13 can be realized through the automatic positioning function of merchant equipment.

The aluminum foil pulling piece 3 and the aluminum foil cover 2 are integrally formed, and the aluminum foil pulling piece is more convenient to process. Compared with the prior art that only one pull tab is provided, the aluminum foil pull tab 3 and the aluminum foil cover 2 are integrated, so that only a plurality of aluminum foil pull tabs 3 need to be manufactured in the embodiment during punching and cutting, and cut aluminum foil materials are also utilized.

Preferably, referring to fig. 3, the aluminum foil tab 3 can be bent and riveted to the aluminum foil lid 2 by a rivet 31.

After aluminium foil pulling-on piece 3 and aluminium foil lid 2 integrated into one piece accomplished, need buckle aluminium foil pulling-on piece 3 and closely laminate on the upper surface of aluminium foil lid 2, avoid aluminium foil pulling-on piece 3 card on the conveyer belt. In the prior art, the aluminum foil pull tab 3 is usually fixed on the aluminum foil cover 2 by adopting an adhesive manner, but the adhesive is easy to stick, and the experience of consumers is poor. With aluminium foil pulling-on piece 3 through rivet 31 and 2 riveting connections of aluminium foil lid in this embodiment, compare in current viscose mode fixity better, be difficult to open, can not be hung by the conveyer belt on the production line, and do not have the problem that the viscose is stained with, consumer experiences better.

When the aluminum foil pull-tab is used by a consumer, the aluminum foil pull-tab 3 is pulled to release the connection with the aluminum foil cover 2, and then the aluminum foil cover 2 is pulled to open the aluminum foil cover 2. After the aluminum foil lid 2 is completely opened, the aluminum foil pull tab 3 can be folded back in the opposite direction, i.e. folded down toward the area outside the aluminum foil lid 2, to be snapped onto the plastic ring 51 of the can body 4 or the plastic outer lid 5. Because the thickness of the common aluminum foil is 0.09 +/-0.005 mm and is very thin, the aluminum foil is reversely lapped on the can body 4 or the plastic ring 51, the buckling of the plastic outer cover 5 is not influenced, and the covering is more compact.

Further preferably, referring to fig. 3, both the upper surface and the lower surface of the aluminum foil cover 2 are provided with indentation surfaces 21, the shape of the indentation surfaces 21 is the same as that of the regular polygonal opening 12, a portion of the outer periphery of the indentation surface 21 of the lower surface of the aluminum foil cover 2 is used for bonding with the annular bonding portion 11, and the indentation surface 21 of the upper surface of the aluminum foil cover 2 has a local light surface area 22 for spraying and printing a two-dimensional code or an integral code.

The position, size and shape of the specific local optical surface area 22 can be determined according to actual needs, for example, in the embodiment, the local optical surface area 22 is rectangular and is located in the central area of the aluminum foil cover 2, and the indentation surface 21 surrounds the periphery of the local optical surface area 22. The surface of the whole aluminum foil cover 2 adopts a local indentation grain surface 21, and a smooth surface area is reserved in the indentation grain surface 21 on the upper surface of the aluminum foil cover for code spraying or merchant LOGO printing and other functions, so that the surface strength is enhanced, and the merchant can print two-dimensional codes or integral codes on non-indentation smooth surfaces in a spraying mode, and has one more use function.

The cover ring 1 adopts a tinplate cover ring, which is in accordance with the GB/T2520 specification, and the tinning amount is more than or equal to 2.5g/m²The thickness of the cover ring 1 is 0.21 +/-0.005 mm.

The lower surface of the outer ring of the aluminum foil cover 2 is bonded and fixed with the annular bonding part 11 through food-grade reinforced glue. The heat-sealing glue used on the lower surface of the aluminum foil cover 2 is food-grade reinforced glue, so that the pollution risk caused by contact or accidental contact of milk powder can be avoided. Add man-hour, the adhesive on the aluminium foil lid 2 inlayer coats earlier on metal aluminium foil before aluminium foil lid 2 and the heat-seal bonding of lid circle 1, through drying process after, directly the punching press becomes the aluminium foil lid 2 that accords with size of a dimension, carries out heat-seal bonding again on the annular bonding portion 11 of lid circle 1, unites two into one and constitutes the upper cover, and production easily realizes. The aluminum foil cover 2 and the annular bonding part 11 are tightly pressed and sealed, and after the two are sealed, the requirements are as follows: the bursting pressure reaches above 0.1Mpa, the full opening force is in the range of 14-36N, the opening force at 45 degrees is in the range of 10-30N, and the thickness of the aluminum foil material is 0.09 +/-0.005 mm.

In the embodiment, the number of the edges of the regular polygon opening 12 is more than or equal to 6, so that the small opening of the tank is avoided; the number of sides is preferably 6-8 sides, most preferably 6 sides, i.e. the regular hexagonal opening shown in fig. 2; an included angle or an arc angle can be adopted between two adjacent sides of the regular polygon.

The length of each edge (namely the length of the scraping edge 13, namely the width of the scraping plate) must be within a certain distance range, otherwise, the scraping plate is too small to play a powder scraping role (the spoon head can touch the can body 4), the scraping plate is too large, the can opening is too small, the hand can be influenced to enter the can to take powder, and the can opening of the person with the large hand can clamp the hand to cause powder taking difficulty when the milk powder in the can is not much left. In this embodiment it is preferred that the length L of the scraping edge 13 is 3-6cm, i.e. 1.5-2 times the width of a conventional spatula. Wherein the width of the conventional measuring spoon is 2-3cm. By setting a certain size technical parameter for the size of the scraper, the size of the tank opening can be ensured to be suitable for consumers to use. The outer edge of the generally annular adhesive portion 11, i.e. the inner rim edge of the lid ring 1, is at a distance d of 3-7mm, preferably 5 + -0.5 mm, from the outer edge of the lid ring 1, i.e. the outer edge of the can body 4. After the two dimensions of the length L of the scraping edge 13 and the distance d are determined, the heat-seal bonding area of the aluminum foil cover 2 and the cover ring 1 is formed, and the aluminum foil cover 2 is heat-seal bonded in the area and is processed into the upper cover of the milk powder can.

Take the jar of commonly used milk powder 502# as an example, the jar internal diameter (also the internal diameter of can body 4) of this jar type is 126mm (+ 0.4mm-0.2 mm), the inboard punching press of lid circle 1 is regular hexagon, the width on every limit all designs for 60 +/-0.5 mm, two adjacent scraper blades are along opening continuous and incessant setting, the transition circular arc has between two adjacent scraper blades, and the radian of transition circular arc should be more than or equal to 120 degrees, avoid this angle too little to cause the scraper blade too little, the powder effect is scraped in the influence. The width of the scraping plate is 1.5-2 normal measuring spoon widths, and the distance from the outer edge of the inner side gluing area of the cover ring 1 to the edge of the can body 4 is 5 +/-0.5 mm.

Further, this embodiment still provides a milk powder jar, including bottom, can body 4, plastics enclosing cover 5 and the easy tear cover of foretell milk powder jar, bottom and milk powder jar are easily torn the lid and are established respectively at the bottom opening part and the top opening part of can body 4, and plastics enclosing cover 5 covers establishes in the top of can body 4 in order to seal the easy tear cover of milk powder jar.

When the milk powder can is used, the can body 4 and the easily-torn cover (also known as an upper cover) of the milk powder can are combined together to form an empty barrel, the bottom cover is sealed after milk powder is filled, and the plastic outer cover 5 is buckled outside the easily-torn cover of the milk powder can. This embodiment mainly improves milk powder jar easily tears lid, mainly has two kinds of structural style at present to plastics enclosing cover 5, specifically as follows:
