Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a resin-made container-containing beverage using so-called aseptic filling for filling a container into a container in a completely aseptic state, and a resin-made container-containing beverage.

[0002]

2. Description of the Related Art Generally, beverage filling methods include aseptic filling and hot pack filling. Aseptic filling is to sterilize a PET bottle (polyethylene terephthalate container) with a chemical rinse, sterilize with water, and then fill the PET bottle with a sterilized beverage at room temperature. The hot pack filling is to fill a PET bottle with a beverage heated to a high temperature (about 80 to 100 ° C.). In such a hot pack filling, since the hot beverage is filled, the mouth portion is crystallized and the body It uses a heat-resistant bottle that also has improved heat resistance.

Compared to hot pack filling, aseptic filling can improve the sterilization condition, so that there are no restrictions on the content of the beverage and the like, and since the filling temperature can be lowered to the room temperature level, filling of beverages with good flavor and the like can be performed. Is possible. Further, since the container used for aseptic filling generally does not need heat resistance because it is filled at room temperature, it has lower heat resistance and is thinner than a container for hot pack filling.

In recent years, in the case of selling a product in a container made of resin in a store in winter, etc., the beverage can is put on a heating plate and stored in a can warmer for heating to warm the beverage (about 55 ° C.). (~ 60 degrees Celsius) are sold or heated by vending machines. For such warming sales, warming sales of aseptic-filled resin-contained beverages are desired, but since the container for aseptic filling has low heat resistance and is thin, it is heated as it is. Cannot be used for sale. In this case, it is conceivable to use a hot-pack filling container as the aseptic filling container.

On the other hand, as a resin container for the purpose of heating and selling, Japanese Patent Application Laid-Open No. 9-240651 and Japanese Patent Application Laid-Open No. 11-3.
Japanese Patent No. 21839 discloses a technique for suppressing the deformation of the bottom of the container at the time of heating and selling.

[0006]

However, even when a container for hot pack filling is used for aseptic filling,
In the aseptic filling, in consideration of the foaming of the beverage at the time of filling, an air portion (hereinafter referred to as "empty size") is provided in the upper part of the container so that the content liquid (beverage) does not spill at the time of filling. ) And the expansion coefficient of the gas in this empty part is large, and the pressure rise of the container body is large when heated,
The basic shape of the container may not be maintained. For example, when the pressure in the container body increases, the container body swells, as shown by the chain double-dashed line in FIG. There is a problem to let. On the other hand, the above-mentioned two publications are limited to the technique of suppressing the deformation of the bottom of the container due to the heating or expansion of the container body, and the basic form of the container body due to the pressure increase during heating, particularly the container body. It is not effective in preventing deformation of the basic form.

Therefore, the present invention is capable of heating and selling aseptic-filled resin-contained beverages, suppressing the expansion of the container due to an increase in the internal pressure of the container at the time of heating and selling, and the appearance at the time of heating and selling. It is an object of the present invention to provide a good method for producing a beverage in a resin container and a beverage in a resin container.

[0008]

The invention according to claim 1 is a method for producing a beverage in a resin container, in which a sterilized beverage is filled in a resin container under a sterile environment after sterilizing the inside of the container. It is characterized in that the beverage is filled in a state where the main body is dented inside the container, and the cap is wound up after the filling.

According to the first aspect of the present invention, in the step of filling the beverage by aseptic filling, the container body is deformed so as to be recessed inward, and the beverage is filled in a state where the inner volume is smaller than that at the time of sale. . Since the volume in the container is smaller than that at the time of sale, if the same volume of beverage is filled, the volume occupied by the empty portion in the container can be reduced.
After filling the beverage, the cap is closed to obtain the product. The recess of the container body returns to its original state or some recess remains due to the water pressure of the beverage or the plastic deformation of the container, and the inside of the container body is in a reduced pressure state. Even if some dents are left in the container, it has almost no effect on the shape of the whole container and does not impair the appearance. When the plastic container beverage (product) manufactured in this way is heated, the internal pressure of the container increases due to the expansion of the beverage in the container and the expansion of the air occupying the empty space in the container. Since the inside of the previous container is in a depressurized state, the increase in the internal pressure of the container after heating can be reduced, and expansion and deformation of the container due to heating can be suppressed. Further, the gas expansion rate is significantly higher than the liquid expansion rate, but the volume of the empty space in which air (gas) is enclosed can be reduced and the empty space is in a decompressed state. The effect of can be reduced, and the effect of preventing expansion and deformation of the basic form of the container is large, and in particular, large expansion and deformation of the container that may cause misunderstanding of quality can be prevented. Also, even if the beverage containing the manufactured resin container manufactured according to the present invention is heated at the time of sale, it is possible to prevent the container from being deformed due to an increase in the internal pressure of the container and being difficult to take out by pressing another adjacent container. Furthermore, since the volume of the air enclosed in the empty portion is small, it is possible to reduce the oxidation of the beverage, which is the content in the container, and the quality retention ability is high. For resin containers,
Since hot beverages are not filled like hot pack filling, the pressure resistance required for container materials can be reduced, the degree of freedom in selecting resin materials is high, and the wall thickness of resin containers can be reduced, It is lightweight and easy to dispose of and recycle after use, and is friendly to the global environment.

According to a second aspect of the present invention, in the invention according to the first aspect, when the beverage is filled, the pressing member is pressed against the container body so that the container body is recessed inside the container and the cap is provided. It is characterized in that the pressing of the pressing member is released after the winding is fastened.

According to the invention of claim 2, claim 1
The same effect as that of the invention described in (1) can be obtained, and the container body can be easily recessed by pressing the pressing member against the container body with a predetermined force. Moreover, by using the pressing member, the operation for forming the recess in the container body can be easily performed, and the amount of the recess can be easily adjusted. In particular,

Alternatively, the same effect as that of the invention described in 2 is obtained, and by forming the pressing member into a V-shaped recess, the container body can be held when the beverage is filled, and the stability at the time of filling is good. In addition, it is easy to hold the containers that are moving sequentially, and it is easy to contact and release the containers while moving the containers.

The invention according to claim 4 is the invention according to claim 2 or 3.
In the invention described in (4), the portion in which the container body is recessed is a region located on the back side of the label.

According to the invention described in claim 4,
Alternatively, in the invention described in (3), even when the recessed part does not completely return to the original shape, the recessed part is on the back of the label, so that it is difficult to see and has little influence on the appearance.

According to a fifth aspect of the present invention, in a method for producing a beverage in a resin container filled with a sterilized beverage in a resin container after sterilizing the inside of the container, the temperature of the beverage when filled in a sterile environment. Is higher than room temperature.

According to the fifth aspect of the present invention, since the temperature of the beverage is raised in the aseptic filling, it is naturally cooled after the filling, so that the inside of the container is decompressed by reducing the air in the beverage and the empty portion. It becomes a state. Therefore, when such a product is subsequently heated, the increase in internal pressure of the container can be reduced, and expansion and deformation of the container due to heating can be suppressed. In particular, since the empty part is in a decompressed state, the effect of gas expansion due to heating can be reduced, the effect of preventing expansion of the container and deformation of the basic form is great, and the expansion and deformation of the container causing misunderstanding in quality. Can be prevented. Therefore, when the manufactured resin-made beverage contained in the container manufactured by the present invention is heated at the time of sale, it is possible to prevent the container from being deformed due to an increase in the internal pressure of the container and pressing another container disposed adjacent thereto to make it difficult to take out. Further, in the empty portion, the amount of air enclosed by the vapor pressure of the filled beverage can be reduced and the oxidation of the beverage can be reduced, so that the quality retention ability is high. The temperature of the beverage to be filled is higher than room temperature, but since it is not filled at a high temperature for sterilization like hot pack filling,
Since the heat resistance and pressure resistance required for the container material can be reduced, there is a high degree of freedom in selecting the resin material, the thickness of the resin container can be made thin, and it is lightweight and easy to dispose and recycle after use. And it is kind to the global environment.

In addition, the heat resistance and pressure resistance required of the resin container can be suppressed to a minimum. That is, the reason for setting the temperature to 30 ° C. or higher is that if the filling temperature of the beverage is lower than this, the expansion of the container at the time of hot sale cannot be effectively suppressed. The reason why the temperature is 70 ° C. or lower is that the temperature at the time of hot sale is generally about 55 ° C. to 60 ° C., and if the temperature is 70 ° C. or lower, the expansion at the time of hot sale can be sufficiently suppressed. Also, if the temperature is higher than this, there is a possibility that the quality of the flavor of the beverage may be affected and that the resin container is required to have high heat resistance, which limits the degree of freedom in selecting the container material. is there. The filling temperature of the beverage is
It is preferably 50 ° C to 70 ° C. The temperature is set to 50 ° C. or higher because the difference from the temperature at the time of hot sale is small and the expansion of the container at the time of hot sale can be surely suppressed.

The beverage 1 in a resin container according to the present embodiment is manufactured by aseptic filling. As the resin container 2, a heat resistant container is used and the mouth 4 is crystallized. . Beverage in this resin container 1
Can be heated and sold by the warmer 3 as shown in FIG. The warmer 3 heats the hot plate 5 on which the canned beverage 7 and the resin-contained beverage 1 according to the present embodiment are placed.

The resin-made container (hereinafter sometimes simply referred to as "container") 2 is made of polyethylene terephthalate (PE).
A beverage bottle made of T), which is generally composed of a mouth portion 4 and a container body 14, and further, the container body 14 is composed of a shoulder portion 6, a body portion 8 and a bottom portion 10. . A cap 9 is attached to the mouth portion 4 and sealed.

The mouth portion 4 is whitened and crystallized to provide heat resistance. In this way, whitening and crystallization is performed to enhance the heat resistance, prevent the sealing property of the cap 9 from being deteriorated during heating, and keep the heat treatment to the minimum necessary. In the whitening treatment, PET is injection-molded in a preforming step to obtain a test tube-shaped intermediate molded product, and then the mouth 4 is whitened and crystallized by a crystallizer in the whitening step.

Next, a manufacturing process of the resin-contained beverage 1 according to the present embodiment will be described. In FIG.
When the resin container 2 is supplied to the production line in step S1, the resin container 2 is pre-washed with washing water in step S2. Then, in step S3, a sterilization process using a chemical rinse is performed. A peracetic acid-based bactericide is used as the bactericide. Next, in step S4, rinsing with sterilized water is performed to finish rinsing, and thereafter, beverages are filled at room temperature in steps S5 to S8 of the filling process. The beverage is, for example, a sterilized milk-added coffee beverage.

In step S5, the sequentially conveyed empty containers 2 are held by the pressing members 31 arranged opposite to each other. The pressing members 31 sandwich the container body 8 with the concave portions 33 having a substantially V shape in plan view, The pressing member 31 is moved toward the container 2, and the container body 8 is pressed to recess the body 8. The amount of depression of the body portion 8 can be adjusted by the amount of pressing of the pressing member 31. By recessing the body portion 8 in this manner, the volume inside the container 2 is reduced. The recessed portion of the container 2 is located substantially at the center of the container body 8 in the vertical direction. This part is label 1
This is because it is a back side portion on which 1 is arranged, which is difficult to see from the outside and a large amount of depression can be taken.

In step S6, the beverage is filled while the container body 8 is recessed. Since the beverage is filled while the container is held by the pressing member 31, the beverage can be filled while the container 2 is stable. After filling a predetermined amount of beverage, the cap 9 is wound up in step S8. Then, after tightening the cap, the pressing member 31 is separated from the container 2 in step S8 to release the contact with the container body 8. On the other hand, the cap 9 is sterilized by another process. Step S1
When the cap 9 is supplied in 1, the resin container filled with the beverage in the above step S7 after the preliminary cleaning in step S12, the chemical rinse in step S13, and the finishing rinse step in step S14 as in the resin container 2.

The resin-contained beverage 1 produced in this manner is displayed in the store as it is or cooled in a refrigerator or a vending machine, but in the winter or the like, it is heated by the warmer 3. It can be displayed or heated by a vending machine and sold. When the resin-containing beverage 1 is displayed in a store as it is or cooled, the amount of the dent is small even if the dent 8 remains in the body 8.
It does not affect the basic form of and does not significantly impair the appearance. In particular, since the recessed portion is on the back of the label 11, it is difficult to understand from the outside.

On the other hand, when heated by the warmer 3 or heated by the vending machine, the internal pressure of the container increases due to the expansion of the beverage in the container and the expansion of the air occupying the empty portion 27 in the container. Since the inside of the container before heating is in a depressurized state, the increase in the internal pressure of the container after heating is small, and expansion and deformation of the container due to heating can be suppressed. Since there is little or no deformation of the container due to expansion in the container, it does not hinder the removal from the warmer 3 or the vending machine by pressing another container that is adjacently arranged at the time of heating and selling. In addition, since the volume of the air enclosed in the empty portion 27 is small, it is possible to reduce the oxidation of the beverage, which is the content in the container, and the quality retention ability is high.

It is filled with heated material. The temperature of the beverage to be filled is, for example, about 50 ° C. Other steps are the same as those in the above-described embodiment.

In the second embodiment, since the temperature of the beverage at the time of filling is higher than the room temperature, the beverage and the empty space air are reduced by the natural cooling after the filling, so that the inside of the container is depressurized. Become. Therefore, when such a product is subsequently heated, the increase in the internal pressure of the container can be reduced, and the expansion and deformation of the container 2 due to the heating can be suppressed. In particular, since the empty portion 27 is in a depressurized state, the influence of gas expansion due to heating can be reduced, the effect of preventing expansion of the container 2 and deformation of the basic form is great, and expansion of the container causing misunderstanding in quality. And deformation can be prevented. Further, in the empty portion 27, the amount of air enclosed due to the vapor pressure of the filled beverage can be reduced, the oxidation of the beverage which is the content in the container can be reduced, and the quality retention ability is high. The temperature of the beverage to be filled is 30 ° C.
When filled in a container with various settings in the range of ~ 70 ° C,
Although the amount of deformation of the container at the time of warming and selling varies depending on the filling temperature, the amount of deformation could be made smaller than that of the conventional one when compared to the one filled at room temperature of about 25 ° C.

7 to 9 show a third embodiment. In the third embodiment, a pressure resistant bottle is used as the container 2 and the beverage is manufactured by ordinary aseptic filling as shown in FIG. The container 2 is a container 2 in which the body 8 has a cylindrical shape and the bottom 10 has a petaloid shape, and the beverage is aseptically filled at room temperature under a sterile environment. The petaloid shape is formed by forming a large number of leg portions 12 projecting downward in a curved shape on the container bottom portion 10.

Has a cylindrical shape, and the bottom portion 10 has a petaloid shape to enhance pressure resistance. Further, the wall thickness of the container 2 is made thicker than that of a conventional aseptic bottle (so-called normal bottle) in order to enhance pressure resistance. In the third embodiment,
Since the pressure-resistant bottle is used for the resin container 2, even if the container internal pressure rises when heated and sold, it is possible to prevent the container 2 from being deformed due to the rise of the container internal pressure, and to prevent the other adjacent containers from being disposed. It is not difficult to take out the container by pressing it,
It is possible to heat and sell aseptic filled beverages in resin containers.

The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the invention. For example, in the above-described first embodiment, the beverage to be filled may be heated as in the second embodiment. In this case, a synergistic effect obtained by combining the first and second embodiments described above can be obtained. In the first embodiment, the shape of the pressing member 31 is not limited and may be a rod shape such as a cylindrical shape or a prismatic shape, or the contact portion with the container 2 may be curved.
