Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tube for spice paste having transparency for preventing quality deterioration during storage of the spice paste.

(Prior art) Synthetic resin tubes are used as packaging containers for paste paste such as mustard mustard and paste paste, but these tubes are generally used to prevent the quality of paste paste from being exposed to sunlight or light such as fluorescent light, especially ultraviolet light. It is made of opaque packaging material to prevent deterioration. However, with opaque tubes, the remaining amount of the contents cannot be confirmed from the outside, which poses a problem in terms of use, and since the contents cannot be seen, the tube lacks a fresh feeling, which also poses a problem in terms of product effectiveness.

On the other hand, when a tube is formed from a transparent packaging material, the oils and fats in the spice paste are oxidized by light, particularly ultraviolet light, that enters through the packaging material, and at the same time, the spice paste significantly discolors or turns brown. In particular, in tube containers, an air-bag phenomenon occurs each time the container is used, and oxygen enters the tube. When ultraviolet rays enter the tube in this state, the oxygen significantly accelerates the oxidation of the fats and oils in the spice paste, and at the same time, it causes discoloration of the spice paste.
Browning is accelerated.

(Problems to be Solved by the Invention) An object of the present invention is to provide a tube for spice paste that does not cause the above-mentioned problems and has transparency to prevent quality deterioration during storage of spice paste.

(Means for Solving the Problems) The present invention has been completed as a result of intensive research to achieve the above object, and its gist is that a transparent synthetic resin tube is coated with ultraviolet-blocking ink and/or ultraviolet-absorbing ink. This is a tube for kneading spices with added ingredients.

Various types of transparent synthetic resin tubes are available! 1 [[It is formed from a transparent film made by 1. Specifically, the synthetic resin tube may be formed of a polyolefin film or the like, preferably a laminated film in which the inner and outer layers are polyolefin films and the middle layer is an oxygen-impermeable film such as saponified ethylene vinyl acetate copolymer. It can be formed by Each layer of the laminated film may be adhered to each other via an adhesive layer. The thickness of the film and laminated film forming the synthetic resin tube is 100μ to 750μ, preferably 250μ to 500μ.
It is desirable that it be μ.

In the present invention, an ultraviolet blocking ink and/or an ultraviolet absorber is added to the synthetic resin tube. Examples of the ultraviolet-blocking ink include titanium oxide, iron oxide, red iron oxide, and various pigments. Among the above-mentioned UV-blocking inks, it is preferable to use brownish or yellowish inks with an absorption wavelength of 20 (11μ to 400+μ) in order to increase the UV protection effect. In the case of spices, the quality deteriorates significantly due to UV rays, so this can be effectively prevented by using the above-mentioned brown or yellow UV-cutting ink, and furthermore, the color tone of the spice paste and the tube can be the same color. The appearance of the tube containing the ground spices can be improved.The above-mentioned ultraviolet-blocking ink has a particle size of 18 (
It is preferable to have a thickness of 1111μ or less in order to obtain a good ultraviolet protection effect and transparency in the tube. Any UV absorber may be used as long as it can be blended into the synthetic resin, and specific examples include benzotriazole-based or hydroxyphenyl-based UV absorbers.

The above-mentioned ultraviolet blocking ink and/or ultraviolet absorber can be added to a synthetic resin tube in the following manner so that the tube has transparency. That is,
An example of a method for adding the ultraviolet blocking ink and/or ultraviolet absorber is kneading it into a film forming a synthetic resin tube. Another example is a mode in which it is kneaded into at least one layer of a laminated film forming a synthetic resin tube or an adhesive layer of the laminated film. Yet another example is to produce a coating containing a UV-blocking ink and/or a UV absorber;
An example is an embodiment in which this is applied to the outer surface of a synthetic resin tube.

In addition, when adding ultraviolet-blocking ink and/or ultraviolet absorber to a synthetic resin tube formed of a laminated film whose inner and outer layers are polyolefin films and whose middle layer is an oxygen-impermeable film, both It is preferable to knead the UV absorber into the polyolefin film of the outer layer, or knead the UV absorber into the polyolefin film of the outer layer, and knead the UV blocking ink into the polyolefin film of the inner layer. With these, it is possible to obtain the desired ultraviolet ray protection effect, impart preferable transparency to the tube, and ensure hygiene and safety for the spice paste. Incidentally, an ultraviolet blocking ink and an ultraviolet absorber may be kneaded into the polyolefin film of the inner layer and the outer layer.

When adding a UV-blocking ink and/or a UV absorber to a synthetic resin tube as described above, add the UV-blocking ink at a rate of 0.1 (1/m2 to 1°5!J/m).
UV absorber at a concentration of 0.1 (J/m' to 2.0
It is preferable to add each at a concentration of g/m' in order to impart a good ultraviolet protection effect and transparency to the duplex. still,
Due to the air-pack phenomenon, oxygen tends to enter and remain near the opening of the tube in the duplex, and this area, that is, the opening of the tube, the shoulder area, and the shoulder area of the body are exposed to UV-blocking ink and ultraviolet rays. It is preferable to add the absorbent at a high concentration within the above range. As a guideline for the added concentration of the ultraviolet blocking ink and the ultraviolet absorber in the above case, the former is, for example, 0.40/rn2 or more, and the latter is 0.50/m' or more.

Next, examples of the spice paste to be stored in the tube of the present invention having the above-mentioned structure include kneaded mustard, kneaded fish paste, kneaded wasabi, kneaded chili pepper, kneaded garlic, kneaded plum, and kneaded shiso. Among the above-mentioned kneaded spices, those with a brownish or yellowish color, and those with an oil and fat content of 5% or more (
In particular, the tube of the present invention exhibits a highly desirable quality deterioration effect for tubes with a weight value of 20% or more.

In addition, when the paste paste is yellowish, such as mustard paste (including mustard) and paste paste, turmeric, gardenia yellow pigment, safflower yellow pigment, and safflower are used as coloring materials to make these yellow tones appear. It is desirable to use at least one or more yellow pigments selected from yellow pigments such as yellow pigments.

The ratio of turmeric and yellow pigment to be added is preferably 1 to 0.1 to 2.0 by weight. With the above configuration, it is possible to prevent browning of the ground spice due to ultraviolet rays and maintain a good yellow color tone. Therefore, when the spice paste added with the above-mentioned coloring material is housed in the tube of the present invention, the effect of preventing quality deterioration of the spice paste is synergistically improved.

(Effects of the Invention) According to the spice paste tube of the present invention, in addition to the usability and appearance effect of being able to confirm the content of the paste paste, it also appropriately blocks ultraviolet rays to ensure that quality deterioration of the paste paste is prevented. It is possible to obtain the effect of preventing

Furthermore, by storing a particular color of kneaded spices in a tube containing a particular color of ultraviolet ma-breakable ink, an even better quality deterioration prevention effect and a beautiful appearance can be achieved. Additionally, if the tube is formed from a laminated film, certain layers may be coated with UV-blocking ink and/or
Alternatively, by adding an ultraviolet absorber, it is possible to obtain a good effect of preventing quality deterioration of kneaded spices.

(Example 1) Polyethylene blended with titanium oxide and a benzotriazole-based UV absorber ('NJ titanium am 1.own%, concentration of benzotriazole-based UV absorber 0.5% by weight) was supplied to an extruder for the outer layer. A saponified ethylene-vinyl acetate copolymer was supplied to the middle layer extruder, and polyethylene was supplied to the inner layer extruder. In addition, maleic anhydride-modified polyethylene was supplied to an adhesive layer extruder located between the outer layer extruder and the middle layer extruder and between the middle layer extruder and the inner layer extruder.

An outer layer extruder, an adhesive layer extruder, an intermediate layer extruder, an adhesive layer extruder, and an inner layer extruder are connected in order from the outer layer to the inner layer of a concentric five-layer die whose temperature is set at 200°C. The layers were fused together and extruded as a single parison. This was formed into a 5-layer tube by blow molding. The thickness of the inner layer/adhesive layer/middle layer/adhesive layer/outer layer of the molded tube is 200μ/15μ/30μ/15μ/10, respectively.
It is 0μ.
