Description

Preform for the manufacture of a polymer bottle

The utility model relates to preforms (blanks) used for the manufacture of polymer bottles intended for storage, transportation and consumption of drinking water.

Due to the deterioration of the environmental situation, as well as a decrease in the quality of tap water, a number of foreign and domestic companies pour potable water into large bottles, which are then delivered to consumers.

Bottles are installed in household devices, providing distribution of drinking water both at room temperature and hot, which can be used to make hot drinks, such as tea, coffee, as well as soups, instant cereals.

Known preform for the manufacture of a polymer bottle according to the certificate for utility model JV215567, publication date 10.27.2000, containing a non-inflated neck with a shoulder, the shoulder is made at the level of the neck of the neck and forms a common end surface with it.

The disadvantage of this preform is the impossibility of obtaining a bottle from it, which is appropriate; according to the size of the AKVAMAG household device, which is produced by domestic industry and ensures the distribution of drinking water from a bottle both at room temperature and hot.

The proposed utility model is aimed at creating a preform for the manufacture of a polymer bottle designed for use in conjunction with an AKVAMAG household appliance.

The technical result achieved by the implementation of the inventive utility model is the convenience of its operation and the production of bottles from it, suitable for use on efficient bottling equipment available on the domestic market.

In addition, the technical result is to achieve the optimal balance between consumer properties and the cost of production and transportation and to reduce the total cost of the bottled product.

This technical result is achieved due to the fact that in the preform for the manufacture of a polymeric bottle containing an inflatable neck with a shoulder and a housing, a distinctive feature is that the inner diameter of the neck is 26.0 mm and the wall thickness of the neck is 0.5 - 1, 0 mm

Since the shape and size of the neck do not change during the manufacture of the polymer bottle from the preform, the execution of the neck of the preform with the above dimensions ensures that the bottle made from it corresponds to the installation position on the AKVAMAG household appliance.

On the outer side of the upper part of the neck of the preform, a thickening in the form of a helical spiral containing at least two turns can be performed.

The thickening in the form of a helical screw serves to wind the cork and can be used to install a dispenser or attach for other purposes.

The neck of the preform may be provided with an additional shoulder. The diameter of the lower flange is larger than the upper.

This embodiment of the collars provides a denser and more reliable connection made from the preform of the bottle to the device or for other purposes.

The essence of the described utility model is illustrated in FIG. 1.

The preform for the manufacture of a polymer bottle contains a neck 1 with a shoulder 2, a housing (not shown in the drawing), a thickening 3 in the form of a helical spiral and an additional shoulder 4. The inner diameter of the neck d is 26.0 mm, the wall thickness of the neck b is 0, 5 - 1.0.

The thickening 3 in the form of a helical spiral on the outer side of the upper part of the neck 1, contains at least two turns.

The diameter of the lower flange 4 is larger than the diameter of the upper flange 2.

The proposed utility model can be used in blow molding machines for the manufacture of a 3-liter polymer bottle. Such a bottle, due to the above-mentioned features of the neck of the preform from which it is made, is suitable for use in the AKVAMAG household appliance, which is produced by the domestic industry and ensures the distribution of drinking water from a bottle as room

temperature and hot.
