Ice making device for used plastic bottles

Abstract

This invention provides an ice-making device that can produce ice in a short time by reusing used plastic bottles as ice molds and efficiently cooling them. [Solution] The device comprises a metal cap 1 that can be attached to the mouth of a PET bottle 3, and a conical metal shaft 2 that is integrally formed with the metal cap or fixed as a separate part. By bringing the conical metal shaft into direct contact with the liquid 4 inside the PET bottle, cold air from the outside is efficiently transmitted through the conical metal shaft, making it possible to generate ice for beverages and food in a relatively short time using a PET bottle.

Description

Technical Field

[0005]

[0001] The present invention relates to an ice-making tool for freezing liquids in used or reusable plastic bottles, and particularly to an ice-making tool for plastic bottles that utilizes the heat conductivity of metal to improve the freezing speed.

Background Art

[0002] Conventionally, when freezing beverages in plastic bottles to obtain ice, it depends on external cooling such as in a freezer, and there is a problem that it takes time to freeze because it is cooled only from the outside of the plastic bottle.

Summary of the Invention

Problems to be Solved by the Invention

[0003] An object of the present invention is to provide a tool that can reuse a used plastic bottle as an ice mold and efficiently cool the liquid inside the plastic bottle to generate ice in a short time. Another object is to prevent the problem that the tool becomes stuck to the ice after freezing and cannot be removed, and to enable safe and efficient use.

Means for Solving the Problems

[0004] The ice-making tool according to the present invention includes a metal cap that is detachably attached to the mouth of a used plastic bottle, and a conical metal shaft that is integrally formed with the metal cap. The conical metal shaft is disposed in the liquid contained inside the plastic bottle, and directly transfers external cold air to the liquid by heat conduction of the metal. Also, by making the shaft conical, it becomes possible to easily pull it out from the ice generated after freezing.

Effects of the Invention

[0005] According to the present invention, the liquid inside the plastic bottle can be efficiently frozen by internal cooling with the metal shaft, and ice can be generated in a short time. Furthermore, its conical shape allows for easy removal of the tool even after freezing, and after ice formation, it can be safely used by replacing it with the original plastic cap of the PET bottle. [Brief explanation of the drawing]

[0006] [Figure 1] This is a cross-sectional view showing the ice-making device according to the present invention attached to a plastic bottle. [Figure 2] This is an explanatory diagram showing the configuration of the metal cap and conical metal shaft of the ice-making device according to the present invention. [Figure 3] This is an explanatory diagram showing the procedure for using the ice-making device according to the present invention, illustrating in order the steps of attaching it to a PET bottle, ice generation by freezing, and removal after ice generation. [Modes for carrying out the invention]

[0007] The ice-making device according to this invention comprises a metal cap that is detachably attached to the mouth of a reusable PET bottle, and a conical metal shaft formed integrally with the metal cap. To use the product, fill the PET bottle with liquid and attach the metal cap according to this invention to the mouth of the PET bottle. Then, place the PET bottle in a freezer, and the cold air from outside will be transferred to the liquid inside the PET bottle via the metal shaft, cooling it efficiently. After the liquid freezes, the conical shape prevents it from sticking to the ice, allowing it to be easily separated from the ice by gripping and pulling off the metal cap. The original resin cap can then be attached to the PET bottle, making the ice safe to use. Therefore, the metal cap and shaft can be used independently of the PET bottle body, and a single metal cap and shaft can be repeatedly applied to multiple PET bottles. [Examples]

[0008] An embodiment of the ice-making device according to the invention will be described. To use it, a used or reusable PET bottle is filled with liquid, and the metal cap according to the invention is attached to the mouth of the PET bottle. When the PET bottle is then placed in a freezer, the cold air from the outside is directly transmitted to the liquid inside the PET bottle via the conical metal shaft formed integrally with the metal cap, and the liquid is efficiently cooled. After the liquid freezes, adhesion to the ice is suppressed due to the conical shape. As a result, the metal cap can be easily separated from the ice by grasping it and pulling it out axially. After that, the original resin cap can be attached to the PET bottle, and the ice can be safely used. Furthermore, the metal cap and metal shaft can be used independently of the PET bottle body and can be applied sequentially to multiple PET bottles. [Industrial applicability]

[0009] The ice-making device according to this invention can be used to produce ice for beverages and food, and it is possible to obtain ice in a relatively short time using existing PET bottles. Specifically, it is suitable for producing ice for beverages and cooling food in ordinary households, as well as for quickly obtaining ice for food and beverages in outdoor activities, sports, and leisure. Furthermore, since it does not require special containers and can utilize existing PET bottles, it can be manufactured and supplied at low cost. Therefore, this invention has industrial applicability in the field of daily necessities related to food and beverages. [Explanation of symbols]
