Description

[Detailed description of the invention]

(Field of Industrial Application) The present invention relates to a container filled with a beverage containing gizzard of citrus fruit such as mandarin orange, summer mandarin orange, orange, lemon, grapefruit, and Iyokan, and a beverage liquid such as fruit juice or sugar solution. , More specifically, it relates to a beverage container filled with citrus fruit sandbags, which allows the sandbags and drinking liquid to flow into the consumer's mouth at an appropriate rate when the consumer eats or drinks the beverage. . (Prior art) In recent years, citrus fruit sandbags and drinking liquids mainly composed of citrus fruit juice, sugar solution, or a mixture thereof have been packaged together in metal cans, glass bottles, paper,
Filling containers such as composite containers formed by laminating two or more different materials such as metal and plastic,
There are some that allow you to eat and drink not only drinking liquid but also small fruit grains (sandbags) at the same time. The consumption of this beverage has grown rapidly, and containers filled with sand-filled beverages of various types of fruit, grain content, and juice content in the drinking liquid are now being produced in large quantities. . (Problems to be solved) By the way, partially damaged sandbags may float up in the drinking liquid, which may cause problems when filling containers with drinks, and may also impede the flow of drinks from the containers. Therefore, most of the sand bags in beverage containers currently on the market are treated appropriately and settled at the bottom of the container. Therefore, if you do not shake the container well before or during drinking to disperse the precipitated sandbags into the drinking liquid and drink it up within a short period of time, the sandbags and the drinking liquid will not mix properly. The drawback was that it did not provide a comfortable drinking experience. Furthermore, even after the container had been shaken well and all the drinking liquid had been drunk, it was often observed that sandbags still remained attached to the bottom and side walls of the container. SUMMARY OF THE INVENTION The object of the present invention is to provide a citrus fruit sand-filled beverage container that eliminates the above-mentioned drawbacks. (Means for Solving Problems) According to the present invention, in a sealed container filled with citrus fruit gizzard and a drinking liquid such as fruit juice or sugar solution, an inert gas such as nitrogen or argon is used. , the internal pressure of the sealed container is 0.3 to 1.5 at 25°C.
A container filled citrus fruit sand-filled beverage filling container is obtained, characterized in that the content is Kg/cm ² . (Function) In the container of the present invention, when the container is opened at room temperature, inert gases such as nitrogen and argon, which had been dissolved in the drinking liquid due to the pressure of 0.3 to 1.5 Kg/cm ² inside the container, are released when the container is opened. Due to the decrease in the pressure inside the container, the inert gas bubbles form in the drinking liquid and escape into the atmosphere. When these inert gas bubbles rise in the drinking liquid, some of them reach the surface of the sand bag that has not surfaced. This increases the buoyancy of the sandbag, causing it to float to the top of the drinking liquid. This occurs even if the drink is transferred to another container such as a cup. When sandbags float to the top of the drinking liquid,
It lasts for about 1 to 5 hours after the container is opened, so if you eat or drink by tilting the filled container or the cup into which the contents have been transferred, the sandbag and drinking liquid will be in the mouth of the person eating and drinking in a suitable proportion. flows into. Therefore, the drinker can eat and drink the drinking liquid and the sandbags at the same time in appropriate proportions, and almost no sandbags remain in the container. Note that unlike carbon dioxide and the like, inert gas such as nitrogen gas does not change the taste of the beverage even if it is dissolved in the beverage, so there is no problem in eating or drinking it immediately after sealing the container. (Example) Next, an example of the present invention will be described. Body thickness is approximately 0.10mm, bottom thickness is approximately 0.33mm
Store in a tin DI can with an internal volume of approximately 270ml at room temperature (25℃).
After filling 50g of tangerine sand bags in good condition, 200g of tangerine juice (BX1.2) at 93℃ was filled.
1.8 seconds before tightening the can lid, drop 0.1 ml of liquid nitrogen, then tighten the can lid to seal the can, and heat at 95℃ for 3 minutes.
After being sterilized for 1 minute, it was immediately cooled with water to room temperature, yielding a mandarin orange juice drink with a can internal pressure of about 1 kg/cm ² on average. Also, for comparison purposes, dropping liquid nitrogen was omitted.
A canned mandarin juice drink containing sand was produced under all other conditions. Tables 1 and 2 show the results of open can analysis of these cans and the results of investigating the number of sandbags remaining in the can after the contents were transferred to a container after opening.
Shown in the table.

[Table] (Note) Regarding the behavior of sandbags, no change was observed depending on the length of the canned storage period.

[Table] Five cans each were tested.
In addition, we produced canned mandarin oranges with sand casing by changing the internal pressure of the can by changing the dripping conditions of liquid nitrogen.
Tables 3 and 4 show the results of investigating the relationship between can internal pressure and sand bag behavior, texture, form, etc.

[Table] From the above results, in order for consumers to be able to eat and drink sandbags and drinking liquid at the same time in a properly mixed state, it is necessary to mix the drinking liquid in the container after opening or the potable liquid that has been transferred. It is necessary that many sand bags are floating in the upper layer, and for this to happen, the internal pressure of the container must be 0.3 Kg/cm ² or more at 25°C. It can be seen that in order to enjoy the pleasant feeling of chewing on the fruit, the internal pressure of the container must be 1.5 kg/cm ² or less. In other words, if the internal pressure of the container is less than 0.3 kg/ ^cm2 , most of the sandbags will remain settled even after the container is opened, and the container must be shaken and drunk within a short period of time. However, a large amount of sandbag remains in the container.
Furthermore, if the internal pressure of the container exceeds 1.5 kg/cm ² , more sand bags will be destroyed, making it impossible to enjoy the pleasant feeling of sand bags. (Effects) As mentioned above, in the container of the present invention, the sand bag at the bottom of the container floats to the top of the drinking liquid after the container is opened, so the opening of the container can be opened without shaking the container. By simply tilting the container toward the mouth of the person eating and drinking, the sandbags and the drinking liquid flow into the person's mouth in a properly mixed state, so the person eating and drinking can eat and drink the sandbags and the drinking liquid at the same time. In addition to allowing you to enjoy the original taste of sand-filled beverages, such as the pleasant feeling of swallowing the two together, and the pleasant feeling of the soft sand in the bag, the container after eating and drinking is Since almost no sandbags remain, the diners will not feel dissatisfied with leftover food. In addition, the container-packed sand-filled beverage of the present invention can be produced by simply incorporating a small drop of inert liquefied gas or an inert gas injection step into the conventional container-packed sand-packed beverage manufacturing process. It does not significantly increase manufacturing costs and has great practical value. In this example, liquid nitrogen was used as the inert gas, but other inert liquefied gases such as liquid argon and liquid neon may be used, and gaseous nitrogen, argon, neon, etc. It may also be press-fitted into the liquid and/or container. Further, as a method for producing the beverage, the above-mentioned method is preferable because it hardly changes the conventional production process, but other methods may of course be used. Furthermore, containers for filling beverages are not limited to metal cans.
Any glass bottle, plastic container, or composite container may be used as long as it can withstand the internal pressure of the container of the present invention.
