As described above, with regard to tea beverages such as coffee beverages, green tea, and roasted tea, it is practiced to sell PET bottled beverages in a heated state in a dedicated bowl called a hot bender. However, it has been pointed out that even when a warmed bottled beverage is purchased, it cools quickly in the cold winter season.
Once the bottled beverage is cooled, it is difficult to reheat at home because it is not designed to be heated by a microwave oven if there is no dedicated appliance. Incidentally, in the case of a plastic bottled beverage, heating with a microwave oven may cause damage to the container or deformation, and therefore, a label or the like that prohibits heating with a microwave oven is often described. In particular, it is necessary to pay particular attention to the remaining amount of beverage since there is a possibility of sudden boiling when the microwave is heated in a state where the remaining amount of beverage in the container is small.

  The present invention is intended to provide a new beverage filling bottle for warming a microwave oven that can be safely heated in a microwave oven.

  The present invention is a beverage filling bottle for heating a microwave oven provided with a transparent plastic bottle container body for filling a beverage and a lid, and a plastic film (referred to as “label”) is attached to the outer periphery of the bottle container body. The label is provided with a belt-like window portion that allows the capacity of the beverage present in the bottle container body to be visually observed in the vertical direction, and at a position along the window portion. The present invention proposes a beverage filling bottle for heating a microwave oven having a configuration in which the output of the microwave and the heating time are displayed according to the volume of the beverage present in the bottle container body.

  The beverage filling bottle for heating microwave ovens proposed by the present invention is provided with a window on the label for viewing the volume of the beverage present in the bottle container body, and according to the volume of the beverage present in the bottle container body. Since the output and heating time of the microwave oven are displayed, the volume of the beverage present in the bottle container body is confirmed at the window, and the output and heating time corresponding to the beverage volume are set in the microwave oven. And it can heat safely with a microwave oven by heating in the state which removed the cover.

It is the side view which illustrated the drink filling bottle for microwave oven warming concerning an example of the embodiment of the present invention.

And a bottle container provided with a lid 3.

  The type of beverage to be filled is not particularly limited. However, since it is a beverage heated in a microwave oven, for example, tea beverages such as green tea, hoji tea, oolong tea, black tea and jasmine tea, and beverages such as barley tea, coffee and cocoa can be preferably exemplified.

The bottle container body 2 is preferably made of a transparent plastic. However, the term “transparent” includes translucent and colored transparency, and it is only necessary to be visible through the bottle container body to the extent that the content can be confirmed.
The bottle container main body 2 may be heated by a microwave oven with the lid 3 removed. From this point of view, the material of the bottle container body may be deformed when heated in a microwave oven, but is preferably a resin material that does not melt. Examples thereof include polyethylene terephthalate (referred to as “PET”), polypropylene, polyethylene, and the like. Further, from the viewpoint of heat resistance, for example, at least the opening 2c to the neck 2b of the bottle container body 2 are preferably formed from crystallized PET.
In addition, a part of bottle container main body 2 may consist of a different material.

The thickness of the body of the bottle container body 2 is preferably 180 μm to 350 μm because it is difficult to be deformed when heated in a microwave oven, but is preferably as thin as possible in terms of cost. Alternatively, it is 330 μm or less, more preferably 190 μm or more or 320 μm or less.
More specifically, the body of the bottle container main body 2 is preferably made of PET having a thickness of 180 μm to 350 μm, more preferably 185 μm or more and 330 μm or less, and more preferably 190 μm or more and 320 μm or less. Among them, it is particularly preferable that the thickness is 200 μm or more or 300 μm or less.

The ratio of the weight (mg) to the capacity (ml) of the bottle container body 2 is preferably as described above from the viewpoint of strength and the like, and is preferably 60.0 mg / ml or less.
From this point of view, the ratio of the weight (mg) to the capacity (ml) of the bottle container body 2 is more preferably 30.0 to 60.0 mg / ml, and more preferably 30.0 mg / ml or more or 50.0 mg / ml. It is particularly preferably 3 ml or less, particularly 35.0 mg / ml or more.

  The shape of the bottle container main body 2 may be any shape as long as the upper end portion of the body portion 2a having a bottomed cylindrical shape is narrowed and has a neck portion 2b and an opening portion 2c. Proper provision of ribs and the like is optional.

The bottle container body 2 preferably has a beverage filling capacity per unit height of 2.00 to 4.00 (mL / mm). If the beverage filling capacity per unit height is 2.00 (mL / mm) or more, since the diameter of the container is sufficiently large, heat is uniformly applied to the beverage when heated in a microwave oven, and bumping is difficult. can do. On the other hand, if the beverage filling capacity per unit height is 4.00 (mL / mm) or less, distribution will not be difficult.
From this point of view, it is more preferable that the bottle container body 2 has a beverage filling capacity per unit height of 2.20 to 3.80 (mL / mm), among which 2.50 (mL / mm) or more or 3 .20 (mL / mm) or less, more preferably 2.80 (mL / mm) or more, or 3.20 (mL / mm) or less, more preferably 2.90 (mL / mm) or more. It is particularly preferred.

As shown in FIG. 1, the label 4 is provided with an output of a microwave oven and a display of a heating time according to the capacity of the beverage present in the bottle container body 2 at intervals in positions along the window portion 5. 6 is preferably provided.
As a specific example of the microwave output and heating time display 6 according to the capacity of the beverage present in the bottle container body 2, for example, as shown in FIG. 1, the capacity of the beverage present in the bottle container body 2 is 200 mL. Next to the position corresponding to the position, in other words, next to the position at a predetermined height from the container bottom 2d of the window portion 5, for example, (600W, 30 seconds) (500W, 40 seconds) is displayed, and the bottle container body 2 Next to the position corresponding to the volume of the beverage 300 mL present inside, in other words, next to the position at a predetermined height from the container bottom 2 d of the window 5, for example, (600 W, 40 seconds) (500 W, 50 seconds) For example, next to a position corresponding to a capacity of 400 mL of beverage present in the bottle container body 2, in other words, a position placed at a predetermined height from the container bottom 2 d of the window portion 5, for example (600 W, 50 seconds) (5 0W, can be 60 seconds) to display examples. However, it is not limited to such an example.

  As shown in FIG. 1, the label 4 may include a display 7 that requests that the lid be removed when heating in a microwave oven. As an example of the display 7, for example, “Be sure to remove the cap and then warm it with a microwave oven” can be cited. However, it is not limited to such an example.

The label 4 may have other descriptions.
For example, you may show the attention at the time of heating with a microwave oven. For example, “If the cap is squeezed and heated, the container may rupture or the content liquid may spout when the cap is removed.” “The heating time varies depending on the amount and temperature of the content liquid.” “If heated too much, the liquid may spurt out, and the burnt or container may be deformed.” Do not use auto (automatic) heating, such as “Random function”. “Please only heat in the microwave once. Container may be deformed.” “Please heat only one at a time.” “Warm with less than 200 mL remaining is recommended. “Do not refill with another liquid and do not warm.” “Do not warm the range with your child alone.” However, it is not limited to these.

In the present specification, when expressed as “X to Y” (X and Y are arbitrary numbers), “X is preferably greater than X” and “X is preferably greater than X” unless otherwise specified. The term “preferably smaller than Y” is included.
Further, in this specification, the expression “more than X” (X is an arbitrary number) includes the meaning of “preferably greater than X” unless otherwise specified, and “Y or less” (Y is an arbitrary number) When expressed as (numerical), it means “preferably smaller than Y” unless otherwise specified.

  Next, tests conducted in connection with the present invention will be described.

  In this test, we verified how many times the liquid temperature would be (° C) when a predetermined amount of green tea was left in a 500 mL capacity PET bottle with the lid removed and the microwave oven was heated under predetermined conditions. .

At this time, as shown in FIG. 1, the used PET bottle has a shape of the bottle container body having a neck portion and an opening portion with the upper end portion of the body portion having a cylindrical shape with a bottom surface narrowed. The thickness of the body of the bottle container body was 235 μm on average, although there was some variation depending on the site, and the ratio of the weight (mg) to the capacity (ml) of the bottle container body was 43.3 mg / ml. The beverage filling capacity per unit height of the bottle container body is 3.07 (mL / mm), the ratio of the width dimension to the height dimension of the bottle container body is 0.42, and the height of the bottle container body is 171 mm. there were.
The PET bottle was filled with a green tea beverage (viscosity: 10.0 cP or less).

  Change the amount of liquid in the container for each liquid temperature before heating (3 ° C, 20 ° C, 35 ° C) (200 mL to 400 mL), change the heating time according to the amount of liquid in the container, It heated at 600W with the microwave oven made from a company, and measured the liquid temperature after heating. Moreover, this measurement was performed with HP and NS, respectively.

  The HP is a filling method for sterilization in a container by filling a heated beverage for sterilization, and the NS is “Non-Sterilant” (non-sterilant = do not use a bactericidal agent). It means a method of filling a beverage liquid at room temperature into a container that has been preliminarily sterilized by heating.

In general microwave ovens, the heating time can be set by pressing a button or by rotating the dial. However, if the heating time is about 30 seconds or less, it is difficult to set the correct time. It turned out to be a factor of heating.
Therefore, it was found that the amount of the beverage liquid is desirably 200 ml or more so that the heating time to about 50 ° C. at which it can be safely consumed is 30 seconds or more.
Further, in the above microwave oven heating under various conditions, safety problems such as container deformation did not occur in any case.
