Abstract

To provide a container suitable for a beverage to be tasted in a state of being mixed with ice particles.
It can withstand fluctuations in volume and internal pressure that occur when a beverage changes from a liquid-only state to a state where ice particles are mixed in the liquid, or from a completely frozen state to a state where ice particles are mixed into the liquid. In this way, a PET (polyethylene terephthalate) bottle 1 is a prismatic one that can absorb changes in internal pressure due to panel deflection on each side, and a cap 2 that seals the mouth of the PET bottle 1 at least on both the inside and outside The label film 3 is made of PP (polypropylene) or PE (polyethylene) that can follow deformation.

Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a PET bottle container for beverages to be tasted in a state where ice particles are mixed in a liquid.
[0002]
[Prior art]
In recent years, as a container for beverages such as coffee, juice, tea, etc., a PET (polyethylene terephthalate) bottle mouth filled with a beverage is sealed with a cap, and a label film is shrink-bonded to the outer periphery of the PET bottle and used frequently. It has come to be.
[0003]
The PET bottle of this container uses a relatively low rigidity that can withstand decompression when the beverage is filled at a high temperature and then returned to room temperature, and the cap has an inner surface and an outer surface of the mouth of the PET bottle. Alternatively, one that seals only one of the top surfaces is used, and OPS (orientated polystyrene) or PET shrink film having poor followability to deformation is used for the label film.
[0004]
[Problems to be solved by the invention]
By the way, a beverage with a high sugar content does not freeze even when cooled to −12 to −3 ° C. When a shock is given by shaking or tapping a container in such a supercooled state, bubbles in the liquid are seeded. It instantly changes to a sherbet with ice particles.
[0005]
However, even if the beverage to be tasted in such a state is to be provided in the container as described above, the container as described above can be used for freezing the beverage as noted on the label film. This creates a problem.
[0006]
That is, if the container as described above is put in a freezer and the beverage is frozen, the bottom surface recess of the PET bottle pops out or the liquid leaks from between the mouth portion of the PET bottle and the cap as the beverage expands. Or the label film tears.
[0007]
Then, this invention makes it a subject to provide the container suitable for the drink enjoyed in the state mixed with ice particles.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention provides a volume generated when a beverage changes from a liquid-only state to a state where ice particles are mixed in the liquid, or from a completely frozen state to a state where ice particles are mixed into the liquid. In order to be able to withstand fluctuations in internal pressure, PET bottles that are prismatic and can absorb changes in internal pressure due to panel deflection on each side, and caps that seal the mouth of the PET bottle at least on both the inside and outside sides The label film used is made of PP (polypropylene) or PE (polyethylene) that can follow deformation.
[0009]
In such a container, if the beverage is shocked from a supercooled state to be mixed with ice particles, or if it is completely frozen and then gradually melted to make it mixed with ice particles, it will accompany freezing. Even if the beverage swells, the phenomenon that the PET bottle is significantly deformed, the liquid leaks from the cap portion, or the label film is torn is prevented.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the accompanying drawings.
[0011]
As shown in FIG. 1, this beverage container is one in which the mouth of a PET (polyethylene terephthalate) bottle 1 is sealed with a cap 2, and a label film 3 is shrunk and adhered to the outer periphery of the PET bottle 1.
[0012]
As the PET bottle 1, a bottle having a prism shape and having a strong ridge portion and capable of absorbing a change in internal pressure by bending of the panel on each surface is used. The shape may be any of a triangular prism shape, a quadrangular prism shape, a hexagonal prism shape, and the like. Moreover, it is good to reinforce the bottom part by providing unevenness in the shape of a pleat.
[0013]
As shown in FIG. 2, the cap 2 should be such that the mouth of the PET bottle 1 is sealed on the inner surface by the annular convex portion 4 of the sealing material and also sealed on the outer surface by the inner upper corner portion 5 of the cap 2. And Moreover, if the top surface can be sealed by the sheet outer peripheral portion 6 of the sealing material, the pressure resistance is further improved.
[0014]
The label film 3 is made of PP (polypropylene) or PE (polyethylene) that expands and contracts following the deformation of the PET bottle 1.
[0015]
When filling such a container with a beverage, for example, for 500 ml, the filling amount is kept around 490 ml (470 to 495 ml) in consideration of an increase in internal pressure due to the expansion of the beverage. .
[0016]
In such a container, if the beverage is shocked from a supercooled state to be mixed with ice particles, or if it is completely frozen and then gradually melted to make it mixed with ice particles, it will accompany freezing. Even if the beverage swells, it is possible to prevent the PET bottle 1 from being deformed significantly, the liquid leaking from the sealed portion of the cap 2, or the label film 3 from tearing. Can be provided safely.
[0017]
【The invention's effect】
As described above, in the container according to the present invention, when a beverage is shocked from a supercooled state to be mixed with ice particles, or after being completely frozen, it is gradually melted to be mixed with ice particles. In this case, even if the beverage swells due to freezing, it is possible to prevent the PET bottle from deforming significantly, leaking liquid from the cap portion, or tearing the label film, so that the beverage can be tasted in a state where ice particles are mixed. Can be provided safely.
