Hot-filling PET (polyethylene terephthalate) bottle convenient to quickly cool

Abstract

According to the hot filling PET bottle convenient to cool rapidly, the bottle cap is taken down from the bottle body, and broken ice blocks or annular ice blocks which can be arranged on the bottle neck in a sleeving mode are added into the cooling groove. Beverages needing to be cooled or to be iced are added into the bottle body through the bottle mouth. The bottle neck is covered with the bottle cap, the bottle cap is rotated, and finally the end, exposed out of the cooling groove, of the bottle neck abuts against the soft sealing gasket, so that the annular sealing ring can be partially inserted into the first annular limiting groove and is connected with the bottle body. Therefore, the cooling groove is sealed, and the bottle mouth is sealed at the same time. Broken ice blocks or annular ice blocks capable of being arranged on the bottle mouth in a sleeving mode are added into the cooling groove so that the beverage in the bottle body can be rapidly cooled or iced. The mode does not influence the concentration of the beverage, so that the taste of the beverage is not influenced. The hot-filled PET bottle convenient to quickly cool is ingenious in design, and beverage in the bottle body can be quickly cooled or iced on the premise that the concentration of the beverage is not affected.

Description

Technical Field

[0001] The utility model relates to the field of hot-filled PET bottles, in particular to a hot-filled PET bottle which is convenient for rapid cooling. Background Art

[0002] PET bottle refers to the polymer produced by the combination of terephthalic acid and ethylene glycol, the plastic material of PET. PET plastic has the characteristics of light weight, high transparency, impact resistance and not easy to break, and can also prevent carbon dioxide gas. PET bottles have strong applicability and are widely used in daily necessities, daily chemical packaging and other fields. PET bottles are processed again by blow molding to form plastic bottles, including bottles used for packaging of cosmetics, medicine, health care, beverages, mineral water, reagents, etc. PET plastic bottles are not only widely used to package carbonated beverages, drinking water, fruit juice, enzymes and tea beverages, etc., which are the most used beverage packaging today, but also widely used in many fields such as food, chemical industry, and pharmaceutical packaging. PET plastic has a wide range of applications in the packaging field, whether it is packaging film or coil, PET plastic is used.

[0003] However, hot filling refers to the process of sealing the bottle immediately after the beverage is fully filled at high temperature (generally 88°C), and then cooling it to room temperature (25°C) in a closed state. The density of the beverage during hot filling is less than the density at room temperature. When the filling volume is constant, the increase in the density of the beverage in the bottle will inevitably lead to a decrease in volume, forming a certain degree of vacuum. The greater the change in density (volume), the greater the vacuum. For example, when the beverage drops from 88°C to 25°C, its volume shrinkage is about 3.2%. In addition, if it is not fully filled, the shrinkage rate will increase to a certain extent because the density change rate of air is greater than the density change rate of water. Traditional hot-filled PET bottles, such as the technical solution disclosed in the patent with application number CN202123098848.7 and invention name A PET hot-filled bottle with an extrusion position, do not have the function of rapid cooling and cannot meet the needs of rapid citation.

The bottle cap 200 and the bottle body 100 are detachably connected.

[0027] A cooling groove 101 is provided in the middle area of ​​the top of the bottle body 100, and a bottle mouth 110 is provided in the middle area of ​​the cooling groove 101 of the bottle body 100. The bottle mouth 110 is a cylindrical tubular structure. One end of the bottle mouth 110 is exposed to the cooling groove 101, and the end of the bottle mouth 110 exposed to the cooling groove 101 is provided with an external thread. A first annular limiting groove 102 is provided on the inner wall at the opening of the cooling groove 101.

[0028] The middle area of ​​the bottle cap 200 is provided with a thread groove 201, and the bottom of the thread groove 201 is provided with a receiving groove 202, and the radius of the receiving groove 202 is greater than the radius of the thread groove 201. The bottle cap 200 is provided with a soft sealing gasket 210 in the receiving groove 202. In the present embodiment, the soft sealing gasket 210 is a soft silicone sheet. In another embodiment, the soft sealing gasket 210 is a soft rubber sheet. The thread groove 201 is adapted to the external thread, and one end of the bottle mouth 110 exposed to the cooling groove 101 is inserted in the thread groove 201 and screwed with the bottle cap 200. One end of the bottle mouth 110 exposed to the cooling groove 101 abuts against the soft sealing gasket 210. The bottle cap 200 is adapted to the cooling groove 101, and the bottle cap 200 is partially inserted in the cooling groove 101.
