Description
Technical field
The present invention relates to the packing box field, particularly a kind of metal storage box and manufacturing approach thereof.
Background technology
At present, the packing container that tin-plate is made is because economy, environmental protection, characteristic such as attractive in appearance replace traditional packing such as paper and plastic cement gradually.Especially in recent years; International well-known quick consumption group company adopts can or can to come packaged food, candy, cosmetics etc. one after another; Obtained the effect that exceeds expectation; Particularly on this buccal tablet product of candy, use little can to render to market, make global pre-capita consumption reach 8 boxes, the market outlook of can are very wide.Yet, because the special processing technology of can, there are the two process structure technical matterss of producing extensively at present:
(1) lid with being connected of box body is: on the inwall of box body, open two holes, penetrate internally as turning cylinder through iron wire and connect, thereby carry out the axial rotation of lid.When factory-assembled, transportation or customer used, iron wire is as easy as rolling off a log in this structure fell in the box, thereby caused the serious food security accident potential of being eaten.
(2) in the junction of lid and box body, axial rotation place and box body bottom all exist very big slit or position, hole with combination place of box body; This just causes the shelf life of products in the box limited; To the candy buccal tablet, its shelf-life can not be longer than six months, and its storage requirement also receives specific limited simultaneously; After particularly taking external packing apart; If can not once it all eat, the candy buccal tablet that then is left is its fragrance or mouthfeel all differs greatly when eating once more, and this also just makes the product marketing achievement of famous brand name have a greatly reduced quality.
At present, all be to stamp warning clause in a certain position of can to point out to the common practice of these two problems, as:
(1) this product contains finding, when edible, please notes to prevent to swallow, and please carefully opens, and is not suitable for child's use etc.;
(2) be stored in shady and cool dry and comfortable place, instant after opening, guard against damp etc.
Because the volume of candy packing box is less, above-mentioned cited warning clause also just is in background usually, is difficult to noticed by the user.Obviously, no matter the little sugar bowl of existing structure is from the angle of food security or from the functions of use aspect of product, all haves much room for improvement.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, provide a kind of simple in structure and can effectively guarantee the metal storage box of food security.
Another object of the present invention is to provide the manufacturing approach of above-mentioned storage box.
The present invention realizes through following technical scheme: a kind of metal storage box, comprise box body and lid, and the lid edge stretches out and connects a turning cylinder, and box body outer wall is fixed with a connecting piece; Connecting strap be provided with two oral areas relative take in the chamber, the two ends of said turning cylinder embed this respectively and two take in the chamber, thereby lid is connected with box body hinge, and turning cylinder is positioned at the box body outside.
Said connecting strap and box body are fixedly connected by welding.During welding, connecting strap and box status are not utilized electric current to pass through resistance as both positive and negative polarity and are produced heat, then two iron plate moments are fused together; Adopt existing numerical control Eltec to realize; The adhere of connecting strap and box body is firm, and the pulling force that can bear 6kg destroys, in appearance; Connecting strap becomes an integral body with the box figure, do not have finding to exist.
Said box body outer wall is provided with and the corresponding inner concave of connecting strap shape, and said connecting strap is fixed on this inner concave outside.
Week forms the turnup limit in the said box body oral area; Said lid is made up of with being not more than all cross sections in the box body oral area and being positioned at the inboard chimeric block of cover plate the cover plate that is not less than box body oral area peripheral cross-section; The edge of said chimeric block is provided with lug boss, and the turnup limit of this lug boss and box body oral area fastens.
Said turning cylinder is connected with the extension of lid cover plate one lateral edges, and the opposite side edge on the lid cover plate is provided with uncapping of outside protrusion and pulls piece.
Be provided with seal ring around the said lid chimeric block.
Said box body is formed by connecting box plate and tubular box sidewall; The turnup limit of inside turnup is formed on tubular box sidewall bottom; Form the turnup limit of outside turnup around the box plate, the middle part forms outside convex surface, forms the circular groove to the box sunken inside around the convex surface; Box sidewall turnup limit is interlocked with box plate turnup limit and is connected, and is marked with sealant in the circular groove.
Said sealant is that primary raw material is the leakproofing material of polyvinylchloride, adopts polyvinylchloride, environment-friendly type plasticizer, auxiliary agent etc., utilizes existing electromechanical integration technology to be heating and curing, and makes its injection and is fixed in the circular groove of box body bottom.
Said box sidewall turnup limit is cylindric overturn structure, and box plate turnup limit is the square overturn structure.
Said box sidewall turnup limit and box plate turnup limit are hook formation in the opposite direction.
When this storage box used, its method of application was identical with existing similar packing box; This storage box adds man-hour, makes earlier each constituent elements of storage box respectively, and lid is fixed on the connecting strap through turning cylinder, and the mode through welding is fixed in the box body outside with connecting strap then, in the circular groove of box body bottom, injects sealant at last and gets final product.
The present invention is used for the manufacturing approach of above-mentioned storage box, specifically may further comprise the steps:
(1) each constituent elements of moulding storage box in advance comprises that chimeric block, turning cylinder and the band of box sidewall, box plate, cover plate, band lug boss taken in the connecting strap in chamber;
(2) cover plate is fixing with the chimeric block welding of band lug boss, form lid; Box sidewall bottom and box plate periphery are carried out turnup limit turnup respectively, through the turnup limit box sidewall are captiveed joint with box plate, form the box body;
(3) turning cylinder is set on lid, through turning cylinder with take in cooperating of chamber, lid is captiveed joint with connecting strap;
(4) adopt the method for welding, connecting strap is fixed on the box body outer wall;
(5), inject sealant in the circular groove that the turnup limit of box sidewall and box plate forms in box body bottom.
Compared with prior art, the present invention has following beneficial effect:
This storage box is at the arranged outside connecting strap of box body; And lid is arranged on the connecting strap through turning cylinder, and to be located at box body inside different with turning cylinder in the current packaging box, can guarantee preferably storage box use or transportation in; It is inner that turning cylinder can not fall into the box body, improved foodsafety; Simultaneously, because turning cylinder is external, the box body need not be provided for installing the through-hole structure of turning cylinder yet, has therefore improved the leak tightness of box body, can prolong the quality guarantee period of food preferably.
The box body bottom of this storage box; Box plate is captiveed joint through the turnup limit of interior turnup and outer turnup respectively with tubular box sidewall; Its fixed effect is better; In the circular groove that its bottom forms, inject sealant simultaneously, effectively improve the overall tightness of storage box, can prolong the quality guarantee period of food preferably.
