Abstract

A polymer bottle and a preform for its manufacture (options).

The utility model relates to nolymer vessels for storing liquids, as well as blanks for the manufacture of these vessels and can be used in the impoverished industry. A blown polymer bottle with elements for fastening when filling and capping is characterized in that annular protrusions and / or grooves are made on the end surface of the neck for thermally closing the bottle with a polymer or metal membrane. In accordance with the first embodiment, the preform for the manufacture of the bottle contains a non-inflated neck with a shoulder, made at the level of the cut of the neck and forming; with it a common end surface. In accordance with the second option, the non-inflated neck of the preform is made conical, expanding, extending to the mouth. No cork is required to seal bottles made from preforms.

Description

A polymer bottle and a preform for its manufacture (options).

The utility model relates to polymer vessels for storing liquids, as well as to blanks for the manufacture of these vessels and can be used in the food industry.

Typically, polymer bottles, as well as blanks for blow molding (preforms), have a threaded neck with a shoulder for screwing the cork (see, for example, RF patent No. 2054356 IPC B 29 C 49/04, publ. 02.20.96).

The objective of the utility model is to create a polymer bottle for capping which does not require a cork.

The problem is solved by the fact that the polymer bottle with elements for fastening when filling and capping, is equipped with annular protrusions and / or grooves made on the end surface of the neck and / or grooves for thermally closing the bottle with a polymer or metal membrane.

The neck of the bz-bottle can be covered with a membrane containing a marking and / or a protective element to identify the contents of the bottle. The security element may be made in the form of a hologram.

The problem is also solved by the fact that the preform for the manufacture of the bottle contains a non-inflated neck with a shoulder, which is made at the level of the cut of the neck and forms a common end surface with it.

at 65 D 1/02 V 49 C 49/00

in accordance with another version of the design, the nreform for the manufacture of a bottle contains a non-inflated neck, made conical, expanding to the mouth.

The indicated distinctive features of the bogie and the preforms for its manufacture make it possible to abandon the use of traditional corks for corking, replacing them with polymer or metal membranes.

In FIG. 1 shows the neck of a proposed bottle.

In Fig.2,3 - embodiments of the neck of the preforms for the manufacture of bottles.

As shown in figure 1, the blown polymer bottle is equipped with a neck 1, on the end surface of which are made annular protrusions 2 and grooves 3 for thermally closing the bottle with a polymer or metal membrane. For the manufacture of the bottle, a preform can be used (Fig. 2) with a shoulder 4, made at the cut-off level of the neck 5 and forming 1; it has a common end surface with it. In accordance with another embodiment (FIG. 3), the preform comprises a conical non-inflated neck 6, expanding; extending to the mouth.

The closure of bottles made of preforms by blow molding is carried out with polymer or metal membranes that are marked and / or at least one protective element to identify the contents of the bottle.
