Abstract

The invention provides a photochromic cigarette package which comprises a visible part of the cigarette package, wherein a photochromic component is arranged on the visible part of the photochromic cigarette package, and the photochromic component can absorb sunlight or ultraviolet light to generate color change. The photochromic cigarette package provided by the invention can enable the cigarette package to show different colors when being irradiated by ultraviolet rays, so that the color change of the cigarette package can be visualized, and the photochromic cigarette package has a direct warning or indicating effect on consumers.

Description

Photochromic cigarette package

Technical Field

The invention relates to the technical field of cigarettes, in particular to a photochromic cigarette package.

Background

The cigarette is a tobacco product which is made by rolling tobacco shreds into strips by using cigarette paper; generally divided into filter cigarettes and non-filter cigarettes. The processed cut tobacco stems are generally mixed and flavored to form cut tobacco storage, and then the cut tobacco storage is subjected to cigarette rolling and packaging to form finished products.

The cigarette package is used for protecting cigarettes from being invaded by natural factors such as sunshine, wind, rain and the like, and preventing loss such as contamination, collision, extrusion, loss, theft and the like. Meanwhile, the cigarette has a means of realizing the use value of the cigarette and increasing the value of the cigarette, and has the functions of anti-counterfeiting and indication for consumers. At present, the market has a plurality of anti-counterfeiting technologies which can be observed by tools, and the optically variable material has multiple effects of anti-counterfeiting, indication or beauty and the like on the cigarette package and is a novel material which can be adopted by the cigarette package.

Disclosure of Invention

In view of the above-mentioned shortcomings of the prior art, it is an object of the present invention to provide a photochromic cigarette package for solving the problems of the prior art.

To achieve the above objects and other related objects, the present invention is achieved by the following technical solutions.

The invention provides a photochromic cigarette package which comprises a visible part of the cigarette package, wherein a photochromic component is arranged on the visible part of the photochromic cigarette package, and the photochromic component can absorb sunlight or ultraviolet light to generate color change.

Preferably, the photochromic component is formed by printing photochromic ink on the visible part of the cigarette packaging box, so that a layered fixed attachment is formed on the cigarette packaging box.

Preferably, the photochromic component is positioned on the side surface of the cigarette packaging box.

Preferably, the photochromic ink comprises the following raw material components in parts by weight:

preferably, the number average molecular weight of the acrylic resin is 40000-50000.

Preferably, the solid content of the waterborne polyurethane is 30-40 wt%. More preferably, the number average molecular weight of the waterborne polyurethane is 100000-120000.

Preferably, the solvent is a mixed solvent of 1,2 butanediol and xylene, and the mass ratio of the 1,2 butanediol to the xylene is 1: (3-8).

Preferably, the glycol ether is selected from one or two of ethylene glycol isopropyl ether and ethylene glycol propyl ether.

Preferably, the antioxidant is selected from one or both of antioxidant 1076 and antioxidant 168.

Preferably, the surfactant is selected from zwitterionic silicone surfactants. More preferably, the surfactant is one or two selected from the group consisting of phosphate betaine and carboxylic acid betaine.

Preferably, the average particle size of the photosensitive microcapsule powder is 3-10 μm.

Preferably, the photosensitive microcapsule powder is selected from light-sensitive microcapsules UVC of hans chemicals, inc. It can absorb ultraviolet light source with specific wavelength, and produce color change (changing into purple, red, blue and yellow) by means of light source energy; when the ultraviolet light source with specific wavelength is not present, the original color can be recovered.

When used in cigarette packaging, this may result in insignificant or no discoloration effects if the raw materials or parameters are selected incorrectly or incorrectly during the production process.

Preferably, the photochromic ink is prepared by mixing the raw material components.

The technical scheme of the invention has the following beneficial effects:

the photochromic cigarette package provided by the invention can enable the cigarette package to show different colors when being irradiated by ultraviolet rays, so that the color change of the cigarette package can be visualized, and the photochromic cigarette package has a direct warning or indicating effect on consumers.

Detailed Description

The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.

Before the present embodiments are further described, it is to be understood that the scope of the invention is not limited to the particular embodiments described below; it is also to be understood that the terminology used in the examples is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention. Test methods in which specific conditions are not specified in the following examples are generally carried out under conventional conditions or under conditions recommended by the respective manufacturers.

When numerical ranges are given in the examples, it is understood that both endpoints of each of the numerical ranges and any value therebetween can be selected unless the invention otherwise indicated. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In addition to the specific methods, devices, and materials used in the examples, any methods, devices, and materials similar or equivalent to those described in the examples may be used in the practice of the invention in addition to the specific methods, devices, and materials used in the examples, in keeping with the knowledge of one skilled in the art and with the description of the invention.

The embodiment of the application specifically discloses sensitization cigarette packing that discolours, including the visual part of cigarette packing be equipped with sensitization parts that discolours on sensitization parts that discolours cigarette packing's the visual part, sensitization parts that discolours can borrow by the change in absorption sunshine or ultraviolet ray production colour. The photochromic component is formed by printing photochromic ink on the visible part of the cigarette packaging box, so that a layered structure is formed and fixedly attached to the cigarette packaging box.

Specific proportions and components of the photochromic inks of examples 1 to 6 are shown in table 1.

TABLE 1

The raw material components of the photochromic ink in the examples 1 to 6 were mixed by weight to prepare an ink product.

The ink products formed in the embodiments 1 to 6 are respectively printed on a cigarette packaging box and a cigarette packaging paper to form a photochromic component, which can show color change under ultraviolet irradiation and can restore the original color when an ultraviolet light source does not exist; the thermal stability of printing ink is higher in this application, can rapid draing to provide lasting abluent mark, place one year back indoor through ultraviolet irradiation still have obvious sensitization discoloration effect.

And (3) testing heat resistance: after being placed at the high temperature of 80 ℃ for 2 days, the color still changes when the glass absorbs sunlight or ultraviolet light, and the anti-light fatigue effect is obvious.

The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention.
