Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a soft drink in a container,
In particular, the present invention relates to a cooling material for maintaining a cold beverage in a plastic bottle for a while.

[0002]

2. Description of the Related Art Soft drinks are not delicious unless they are cold. When pouring into a glass or the like, it is common to drink iced drinks. In 15 minutes, however, the ice melts and loses its cooling effect, and the soft drink tastes thin.

[0003] In recent years, 500 ml of plastic bottles as a packaging form of soft drinks have been conspicuously increasing in convenience stores and the like, and in this case, they often drink directly by mouth without transferring them to a cup or the like. I can't afford ice. Moreover, the volume of 500 ml is too much to drink at a stretch. Unless you are very thirsty, you will have to keep it for an hour or more and finally drink it in several portions. In the meantime, the soft drinks are naturally warm and the refreshing feeling is impaired, and especially in the case of carbonated soft drinks, they are often sweet and difficult to drink and are often thrown away.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a simple cold insulator capable of maintaining a soft drink in a plastic bottle for a while.

[0005]

In order to achieve the above-mentioned object, a floating stick type cold insulating material according to the present invention comprises a hollow cap at the upper end of a synthetic resin stick-shaped case body in which a regenerator is sealed. And a stopper is provided on the peripheral wall of the body of the case body so as to be hooked on the drinking spout of the plastic bottle.

[0006] When the stick floating type cold insulator having the above-mentioned structure is frozen in a freezer and dropped directly into a soft drink from the mouth of a plastic bottle, as the name implies, it becomes like a stick type floating material. Float while standing upright. The special effect of floating in this way is particularly remarkable when the container is an elongated object such as a plastic bottle,
When you tilt the plastic bottle with your mouth to drink the contents, the cold insulator always moves to the opposite side of the drinking spout, and the lower end sticks to the bottom of the plastic bottle and you drink it. It does not get in the way. This behavior of the cold insulator is surely repeated every time the PET bottle is tilted as long as it floats, and when compared to the one that sinks to the bottom and does not move, it looks interesting and also stirs the soft drink This leads to improvement of cooling efficiency.

[0007] If the content is low and the PET bottle must be tilted by 90 degrees or more to drink, there is no point in floating, and the cold insulator comes out from the drinking spout, which is very dangerous. . Therefore, in order to use it in a plastic bottle,
It is an essential condition to have a stopper that catches on the spout of the plastic bottle. The stopper may be in the form of a ring made of an elastic material such as rubber, of course.In addition to making the maximum outer diameter larger than the inner diameter of the PET bottle spout, notches and holes are provided around the stopper. Should not completely block the spout from inside. As another form of the stopper, a pin-shaped or arm-shaped stopper using a hard material may be protruded from the peripheral wall of the case body by, for example, urging with a spring.

Also, as in the invention described in claim 2,
If the stopper made of an elastic material has a semicircular locking piece protruding in a petal shape on the outer periphery of a ring smaller than the inner diameter of the PET bottle spout, the stopper is at the base of the PET bottle spout. This ensures that the cold insulator is prevented from jumping out, and that a gap where the soft drink flows out is always ensured, resulting in excellent functionality and design.

[0009]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing a floating stick type cold insulating material according to an embodiment of the present invention. As shown in FIG. 1, the present cold insulating material has a stick-shaped case body 2 filled with a regenerator 1, a hollow cap 3 covering the upper end thereof, and a brim shaped engaging with the peripheral wall of the case body 2. And a stopper 5.

The material of the case body 2 and the cap 3 is suitably made of polypropylene or polyethylene. The case body 2 is formed in an elongated shape like a test tube, and is filled with a general cold storage agent 1 containing water as a main component,
An inner plug 8 made of an elastic material is press-fitted into the opening and sealed. Since the volume of the regenerator 1 slightly changes with freezing and melting, the air reservoir 9 is always provided to prevent the case body 2 from bursting. The inside of the cap 3 is hollow, and the air stored in this portion acts as a float. In addition, character goods such as small dolls and photographs can be stored in the hollow portion 10, which can further attract children's interest.

[0013] A bee-shaped constriction groove 11 is formed at two places on the peripheral wall of the case body 2 at the same height from the upper and lower ends of the cold insulating material. The ring 6 stops so as to bite into this groove. As shown in FIG. 1 (C), five semicircular locking pieces 7 project from the outer circumference of the ring 6 at equal intervals, and have a shape like a plum blossom. . Although the maximum outer diameter of the stopper 5 is larger than the inner diameter of the drinking opening of the plastic bottle 4, the material is made of silicone rubber, so that it does not lose its flexibility even when cooled by the regenerator 1. Is easily deformed when inserted into the plastic bottle 4. In the present embodiment, the upper and lower stoppers 5 are provided, but this is provided for safety, assuming that the cold insulator is mistakenly placed in the plastic bottle 4 in the opposite direction. Strictly, only the above may be used.

Hereinafter, the use state of the floating stick type cold insulating material of the present invention will be described. When the present cold insulator is frozen in a freezer, inserted into the inside of the plastic bottle 4 from the spout, and dropped into a soft drink, the cold insulator floats in an upright state as a floating as shown in FIG. . When the plastic bottle 4 is tilted as shown in FIG. 3 (a) to drink the contents, the cold insulator always moves to the opposite side of the drinking spout, and the tip is in a state of sticking to the bottom of the plastic bottle 4. It is not in the way to drink. When the contents become low and the PET bottle 4 is tilted by 90 degrees or more as shown in FIG. 3 (b), the cooling material tends to pop out of the drinking spout, but there is no fear that the stopper 5 is caught at the base of the drinking spout. . In addition, since the stopper 5 has a special form as described above, the stopper 5 does not completely block the drinking spout and can be completely drained. After drinking, the cap 3 is designed so that the face slightly comes out of the spout, so if you pinch it, you can easily put this cold insulator into a plastic bottle 4.
Can be removed from the container, washed with water and used repeatedly.

[0013] As described above, the floating stick heat insulating material of the present invention is most effective when used for plastic bottles. However, it can also be used in cases where ice cannot be put, for example, in a mug of beer. Can be kept cool for a long time without thinning. Since there is no regenerator inside the cap, it is not cold even if you hold it with your hand. It is also convenient to use as a muddler for stirring various beverages.

[0014]

The stick-floating cold insulator according to the present invention floats in a vertically standing state like a float, so if you put it in a PET bottle and tilt it for drinking, it will always move to the bottom and drink. But it doesn't get in the way. In addition, there is no danger of jumping out of the spout of the plastic bottle because it has a stopper. 500m if you use this cold insulator
Even if you drink a soft drink in a plastic bottle for about one hour, you can drink deliciously while staying cold.

Further, if the form of the stopper is described in claim 2, the stopper can be completely drained without completely blocking the drinking opening of the plastic bottle, and the design is excellent.
