Description

[Detailed description of the invention]

[Industrial Application Field] This invention relates to decorative bubble gum that can develop a colored pattern on a chewing gum balloon film, and in which the color of the colored pattern changes depending on the length of chewing time of the gum. be. [Prior art] An attempt to develop a colored pattern on the chewing gum balloon membrane of balloon chewing gum was made in Japanese Patent Publication No. 54-38189.
Disclosed in the issue. This chewing gum for balloons contains raw silk, cotton, and other vegetable fibers.
Gluten, animal intestines, fish scales, and collagen are appropriately colored and mixed together, and when the chewing gum is inflated, these decorative substances are distributed in the chewing gum balloon membrane to create a colored pattern. However, this method does not allow raw silk,
A decorative material such as cotton thread is simply added as a colored material, and the color of the decorative material remains constant throughout each stage of chewing and inflation of the balloon membrane. If there is a change, it is due to discoloration due to the elution of colored substances during chewing, and although the color becomes lighter, it can be said that it is almost the same as the original color. In other words, although the chewing gum disclosed in Japanese Patent Publication No. 54-38189 produces a colored pattern on the chewing gum balloon film, the pattern is always the same color and does not change at all and is monotonous. The problem is that children, who are the main buyers of these products, quickly get bored with them. Moreover, the above-mentioned special public service No. 54-38189
The chewing gum of the publication has a fatal defect as a product. That is, the decorative substances added to the above-mentioned chewing gum are vegetable fibers such as raw silk and cotton, and natural products such as fish scales, and all of them are chewing gum balloon membranes (the main component is resin such as vinyl acetate resin) or It has serious defects in that it does not mix well with the gum base, peels off from the balloon film, and gives a feeling of foreign matter when chewing. In addition, the above-mentioned decorative substances are natural products and have their own unique shapes (for example, cotton is linear, scales are scaly), and are subject to these restrictions. The shape of the pattern is almost constant, and together with the fact that the color does not change, children quickly lose interest. [Problems to be Solved by the Invention] In view of the above-mentioned circumstances, the present invention provides a method for chewing gum balloon membranes that has a free shape, changes color with chewing, and that peels off from the chewing gum balloon membranes. The purpose is to provide decorative bubble gum capable of expressing a colored pattern without any color. [Means for Solving the Problems] In order to achieve the above object, the decorative bubble gum of the present invention has a coating structure in which a colored piece of soft synthetic resin is coated with a poorly soluble colored film having a different color. The composition is such that the pieces are dispersed as a pattern-forming substance in a chewing gum balloon membrane. That is, since the above decorative bubble gum uses a soft synthetic resin colored piece coated with a slightly soluble colored film as a pattern forming substance, the balloon film inflated at a shallow stage of chewing is coated with a slightly soluble colored film. The colored pieces covered with
In the balloon membrane that was inflated at an advanced stage of biting, the slightly soluble colored film was eluted and removed by biting during that period, and the colored piece of soft synthetic resin itself appeared, creating a color pattern different from the previous one. Form. Moreover,
The above-mentioned soft synthetic resin colored piece is made of the same synthetic resin as the chewing gum balloon membrane and the gum base, so it blends well with them and does not cause the phenomenon of peeling off from the balloon membrane or causing the sensation of a foreign body when chewing. Moreover, it is highly workable and can be formed into unique shapes such as star shapes and crescent shapes that could not be formed conventionally. Therefore, by appropriately combining the change in color of the color pattern on the balloon film and the shape of the colored piece, a timeless color pattern can be stably expressed on the balloon film. The resin of the above-mentioned soft synthetic resin colored piece can be sufficiently used as long as it is a soft one among various synthetic resins. However, when chewing gum is incorporated into the chewing gum base and integrated with it, the chewing gum balloon film does not develop any pattern, so there is a limit to how low molecular weight it can be. That is, the above-mentioned softness refers to the degree to which the chewing gum does not give a foreign body sensation when chewing and can maintain its own shape. Among soft synthetic resins, it is particularly preferable to use vinyl acetate resin having a degree of polymerization within the range of 1,000 to 38,000. This product satisfies all of the above characteristics. This resin is usually used in the form of a minute film from the viewpoint of the feel when chewing and the decoration of the balloon membrane. The above-mentioned resin can be colored into flakes by adding a coloring agent such as a lake dye during resin synthesis, stretching the resulting colored resin appropriately and cutting it into pieces, or by using a solvent to dye the synthesized resin. This is carried out by dissolving the solution, adding a coloring agent thereto, casting it on a glass plate or the like, drying it to form a film, and cutting the film as appropriate. As the pigments used for coloring, various lake pigments are used as mentioned above, but in addition to these, oil-soluble natural yellow pigments, copper chlorophyll, activated carbon, titanium dioxide, etc. can be used alone or in combination. The slightly soluble colored film covering the soft synthetic resin colored piece produced as described above needs to be colored in a different color from the colored piece. Representative examples are as follows. These include colored films of derived proteins such as gelatin, colored films of natural polysaccharides such as pullulan, carrageenan, guar gum, and xanthan gum, and colored films of collagen, casein, soybean protein, etc. These films are formed by making an aqueous solution of the above-mentioned substances together with a colorant such as a water-soluble dye, and coating the colored piece with the solution by dipping, spraying, adhesion using a rotary kettle, etc., and forming a dry film. This is done using methods such as As the dye used in this case, not only natural and synthetic water-soluble dyes but also dyes such as lake dyes used in coloring the resin can be used. The bubble gum in which the colored pieces of soft synthetic resin coated with the hardly soluble colored film thus obtained are dispersed can be obtained by kneading using a kneader or the like according to a known method, and is not particularly limited. The method of dispersion is not particularly limited either, but from the viewpoint of preventing the peeling of the poorly soluble colored film from the colored piece, it is preferable to add and mix just before kneading the bubble gum. The decorative bubble gum obtained as above is
The colored pieces of soft synthetic resin coated with the hardly soluble colored film are dispersed, and the chewing gum balloon film can develop a unique colored pattern that varies in color depending on the degree of chewing of the gum. [Effects of the Invention] As described above, the decorative bubble gum of this invention has the following effects:
A chewing gum that is inflated at a shallow stage of chewing because it has dispersed covering structure pieces in which colored pieces of soft synthetic resin are coated with poorly soluble colored films of different colors, and these pieces change color as chewing progresses. The balloon membrane and the chewing gum balloon membrane, which is inflated at an advanced stage of chewing, can exhibit colored patterns with mutually different colors, and since the soft synthetic resin colored pieces are mainly made of synthetic resin, they can be molded into any shape. .
Therefore, by appropriately combining the two, it becomes possible to easily create a timeless color pattern on the balloon film. Moreover, since the soft synthetic resin colored pieces are of the same quality as the gum base and blend well with each other, they do not cause serious defects such as peeling off from the gum base or chewing gum. Next, examples will be described. Balloon chewing gum and a soft synthetic resin colored piece with a poorly soluble colored coating were prepared in the following manner. (a) Manufacture of balloon chewing gum The raw materials shown in Table 1 below were blended in the proportions shown in the same table and placed in a kneader according to a conventional method to produce a balloon chewing gum base.

[Table] Next, the ingredients shown in Table 2 are blended into the balloon chewing gum base obtained as described above in the proportions shown in the same table, and the mixture is placed in a kneader and mixed according to the usual method. A red balloon chewing gum base was manufactured.

[Table] (b) Production of colored pieces of poorly soluble colored film and soft synthetic resin Vinyl acetate resin with a degree of polymerization of 4000 as shown in Table 3 below is dissolved in ethyl acetate,
Yellow No. 4 aluminum lake dye was mixed into this solution, which was cast onto a glass plate and dried to produce a yellow vinyl acetate resin film.

[Table] Then, the obtained yellow vinyl acetate resin film was coated by spraying a coloring liquid in the proportions shown in Table 4 below, and the color changed to a red vinyl acetate resin film.

[Table] The thus obtained red vinyl acetate resin film was cut into squares of 2 mm on each side to produce the intended colored pieces of poorly soluble colored film and soft synthetic resin. (c) Manufacture of decorative bubble gum The balloon chewing gum obtained as above and the colored piece of soft synthetic resin with a slightly soluble colored coating were kneaded in the proportions shown in Table 5 below, and the mixture was molded into a plate using a rolling mill. Thereafter, the balloon chewing gum was cut and molded into predetermined dimensions to obtain decorative bubble gum.

[Table] The decorative bubble gum obtained as above is
The whole is a uniform red color. When you chew on this, the pigment contained in the gum body washes away and the color becomes lighter. However, in the case of the poorly soluble colored film soft synthetic resin colored piece, the hardly soluble colored film on the front is mainly composed of gelatin. Since it is composed of a poorly soluble substance, the color does not wash away. Therefore, when the gum is inflated at this stage, the chewing gum balloon film has a red pattern due to the poorly soluble colored coating and soft synthetic resin colored pieces. This red pattern is caused by the fact that the hardly soluble colored film soft synthetic resin colored piece is in the shape of a rectangular film, and is appropriately dispersed in the balloon film to form a red dispersed pattern. Next, when you put the balloon membrane back on and chew the gum again, the poorly soluble colored film on the surface of the soft synthetic resin colored piece washes away, so the yellow vinyl acetate that is the soft synthetic resin colored piece washes away. The remaining resin will appear,
When the chewing gum is expanded at this stage, a yellow dispersion pattern in which square film-shaped yellow vinyl acetate resin is dispersed appears in the chewing gum, unlike the previous chewing gum. That is, according to this decorative bubble gum, two types of color patterns can appear on the balloon membrane depending on the stage of chewing. Example 2 Bubble gum and a colored piece of soft synthetic resin with a poorly soluble colored film were produced in the following manner. (a) Production of balloon chewing gum A balloon chewing gum base was produced in the same manner as in Example 1, and the raw materials shown in Table 6 below were blended into this balloon chewing gum base in the proportions shown in the same table. Blue balloon chewing gum was produced by mixing in a kneader.

[Table] (b) Manufacture of poorly soluble colored coating soft synthetic resin colored pieces Vinyl acetate resin as shown in Table 7 below is dissolved in ethyl acetate, red No. 3 aluminum lake dye is added and kneaded, and glass A pale red vinyl acetate resin film was produced by casting and drying on a plate.

[Table] The pale red vinyl acetate resin film obtained as described above was coated by immersion with a coloring liquid having the formulation shown in Table 8 below to obtain a blue vinyl acetate resin film.

[Table] The blue vinyl acetate resin film obtained as described above was cut into squares of 2 mm on each side to obtain colored pieces of poorly soluble colored film and soft synthetic resin. (c) Manufacture of decorative bubble gum The balloon chewing gum obtained as above and the soft synthetic resin colored piece with the hardly soluble colored film were mixed into
They were blended in the proportions shown in the table, mixed in a kneader, rolled and then cut into predetermined dimensions to obtain decorative bubble gum. The obtained gum has a uniform blue color throughout, and when it is chewed and inflated, the first chewing gum balloon film contains a slightly soluble colored film and a slightly soluble colored film covering the surface of the soft synthetic resin colored piece. A blue pattern is formed by the blue color, and when the piece is chewed and then inflated, the poorly soluble colored film is eluted and removed, and the red color of the soft synthetic resin colored piece itself appears. That is, in this embodiment as well, two types of patterns appear on the chewing gum balloon film over time. Example 3 Balloon chewing gum and a soft synthetic resin colored piece with a poorly soluble colored coating were produced in the following manner. (a) Production of balloon chewing gum A balloon chewing gum base is produced in the same manner as in Example 1, and the raw materials shown in Table 10 below are blended in the proportions shown in the same table and mixed by a conventional method. As a result, almost white balloon chewing gum was produced.

[Table] (b) Production of poorly soluble colored film soft synthetic resin colored piece A pale yellow vinyl acetate resin film was produced in the same manner as in Example 1 using the raw materials shown in Table 11 below.

[Table] The pale yellow vinyl acetate resin film obtained as described above was coated with the coloring liquid shown in Table 12 below, and the color changed to a red vinyl acetate resin film.

[Table] The red vinyl acetate resin film obtained as described above was cut into squares of 2 mm on each side in the same manner as in Example 1 to produce colored pieces of poorly soluble colored coated soft synthetic resin. (c) Manufacture of decorative balloon gum The balloon chewing gum obtained as above and the colored piece of soft synthetic resin with a slightly soluble colored coating are mixed in the proportions shown in Table 13 below, rolled, and then shaped into a decorative balloon. Got gum.

[Table] The obtained decorative bubble gum had a beautiful pattern in which the red colored pieces of the poorly soluble colored coating soft synthetic resin were scattered on a white background. When you bite into this, the above-mentioned red pattern is dispersed and appears beautifully on the balloon membrane that was inflated at the initial stage of biting.Furthermore, the balloon membrane that is inflated after continuing to chew is made of vinyl acetate resin. A pattern of yellow, which is the color of In other words, even in this example, 2
Various color patterns appear on the chewing gum balloon membrane.
