Abstract
The present invention relates to a bottle cap and a producing method thereof. The bottle cap is composed of a metal blank cap and a composite layer, wherein the composite layer comprises a base layer coated on the outer surface of the metal blank cap; a breaking layer is arranged outside the base layer, and the breaking layer has irregular small crackles. The producing method comprises the following steps that a. the base layer is coated with resin materials on the surface of a metal base material, polyisocyanate is used as solidifying agents, the breaking layer is then coated with the resin materials, and the polyisocyanate and amino resin are used as mixed solidifying agents; b. punch forming is carried out so as to form a blank cap; c. heat processing is carried out on the blank cap in a roasting mode or a boiling mode, and temperature is from 100 to 150 DEG C. The bottle cap of the present invention has the characteristics of beautiful appearance and strong counterfeiting prevention performance. The bottle cap can be widely used as packing caps of food, such as alcoholic drinks, diets, cans, oral medicinal liquid, etc., medicine, health care products, etc.
Description
Technical field
The present invention relates to a kind of bottle cap and production method thereof, especially a kind of appearance has the production method of the crown cap and this bottle cap of fracture crack.
Background technology
At present, existing crown cap generally is to cover with resin-coating one deck basic unit at its metal base, applies bright layer in the outside of basic unit again with resin then and forms composite bed.The outside face of such bottle cap makes bottle cap easily by counterfeit not such as special decorative effects such as fracture cracks.
Summary of the invention
In order to overcome existing bottle cap easily by counterfeit deficiency, the invention provides the bottle cap that a kind of outside face has the fracture crack special decorative effect, make that bottle cap is more attractive in appearance also to be not easy, and the production method of this bottle cap is provided by counterfeit.
The technical solution adopted for the present invention to solve the technical problems is: be made up of metal base lid and composite bed, include the basic unit that is coated on the metal base exterior surface in the composite bed, the outside of basic unit also has a crackle layer.
The production method of bottle cap of the present invention comprises that following step: a. applies basic unit with resin material on the surface of metal base, with the polyisocyanates is curing agent, then with resin material coating crackle layer, and with polyisocyanates and amine resin is mixed curing agent; B. punch forming forms the base lid; C. the base lid is heat-treated, heat treatment mode is baking or boiling, and temperature is 100～150 ℃.
The invention has the beneficial effects as follows, rich color, exquisite in texture, beautiful in colour, attractive in appearance and be not easy by counterfeit, therefore have stronger antifalse effect, can extensively be used as in the packaging cover of food such as drinks, diet, can, oral liquid, medicine and health products etc.

The specific embodiment
The present invention is further described below in conjunction with drawings and Examples:
As shown in Figure 1, bottle cap of the present invention is made up of metal base lid 1 and composite bed 2, and composite bed 2 includes and is coated on metal base and covers basic unit 3 on 1 outside face, also has a crackle layer 5 in the outside of basic unit 3.
Between described basic unit 3 and the crackle layer 5 interior bright layer 4 can also be arranged.
In the outside of described crackle layer 5 bright layer 6 outside one deck can also be arranged.
Basic unit 3 is a colored coating, makes bottle cap of the present invention can have different colors.
According to different needs, interior bright layer also can be several layers.
The production method of bottle cap of the present invention comprises that following step: a. applies basic unit 3 with resin material on the surface of metal base, with the polyisocyanates is curing agent, then with resin material coating crackle layer 5, and with polyisocyanates and amine resin is mixed curing agent; B. punch forming forms base lid 1; C. base lid 1 is heat-treated, heat treatment mode is baking or boiling, and temperature is 100～150 ℃.
Because the curing agent that the crackle layer adopts is different with the curing agent that basic unit, bright layer adopt, and makes the crackle layer have the prolong most malleability different with basic unit and inside and outside bright layer.When stamping out the base lid from sheet metal, the resin material of crackle layer ruptures, and is formed with the crackle layer of fitfull fine cracks, and after heat treatment, the crackle of crackle layer just clearly displays.Bright layer is transparent or semitransparent, wherein the effect of interior bright layer is to make the crackle layer present the color of basic unit better, and the effect of outer bright layer is to make the crackle texture of crackle layer more clear, and avoid the crackle layer to peel off from basic unit or interior bright layer, make the outward appearance of bottle cap have the texture of light simultaneously.
Embodiment 1:
As shown in Figure 2, composite bed 2 includes and is coated on metal base and covers basic unit 3 on 1 outside face, also has a crackle layer 5 in the outside of basic unit 3, also has bright layer 4 in one deck between basic unit 3 and the crackle layer 5.
Its production process is: a. applies basic unit 3 with resin material on the surface of metal base, with the polyisocyanates is curing agent, bright layer 4 in applying with resin material then, with the polyisocyanates is curing agent, again with resin material coating crackle layer 5, and with polyisocyanates and amine resin is mixed curing agent; B. punch forming forms base lid 1; C. base lid 1 is heat-treated, heat treatment mode is baking, and temperature is 130 ℃.
