Description

The invention relates to universal means of packaging various piece goods.

Over the past century, along with the development of science and technology, industries of the production of consumer goods have been formed and developed, the goals and objectives of which are to satisfy the growing demand of the population for these goods. Examples of such industries are the automotive industry, electronics, electrical engineering, household appliances, electronic media, perfumes, book printing, etc.

As sales and production volumes of these products increased, the need arose for individual packaging of consumer goods. The objectives of such packaging were to preserve the appearance of the goods, convey to the buyer the name of the product and the brand name of the manufacturer, and attract the potential buyer with their appearance. Due to these qualities and due to the technological effectiveness of production, cardboard packaging of piece goods of mass demand has been widely used. Examples of this are packaging of spare parts for automobiles, various kinds of goods and spare parts for them, electronics, electrical equipment and household appliances, perfumes and toilet water, poured into glass containers, etc.

However, the cardboard packaging of piece goods of mass demand has a number of negative qualities. These qualities include:

- complete exposure to moisture of the packaging itself and the goods packaged in it;

- low efficiency of transport operations, i.e. due to the inability to withstand a significant load, the laying of boxes in height in the vehicle does not exceed a certain number of rows;

- the inability to protect the manufacturer’s trademark from fakes.

All of the above negative qualities are due to the properties of the material from which the packaging is made, that is, cardboard, and the low cost of packaging technology. The obvious conclusion, to replace it with plastic, rests against serious technical, technological and economic obstacles. The geometric shape, sizes and dimensions of piece goods of mass demand are very diverse, and it is very difficult and economically impractical and unproductive to make a mold for each product. Otherwise, the world would have long ago switched to individual packaging made of plastics. A striking example is the transition to plastic bottles for drinks. But there the goods take the form of packaging, and in our case the opposite is required.

The technical result from the use of the invention is to eliminate the above disadvantages, i.e. in creating universal packaging.

The specified result is achieved in that the packaging set contains two covers, respectively, with external and internal threads and at least one tubular element with internal and external threads at their respective ends.

Lids and tubular elements can be made cylindrical, and at least one threaded connection when forming the package is made with the possibility of obtaining a locking device that is destroyed upon opening.

Lids and tubular elements can be made with ribs and can have a serial number.

Based on the fact that any flat figure is described by a circle and volume by a cylinder, the following packaging design for piece goods of mass demand from a prefabricated plastic structure is proposed as a technical solution.

It consists of:

- from a hollow cylinder, mainly with threaded necks at both ends, at one end with an internal thread, and at the second with an external thread;

- two caps with threaded ends, also one of the caps with an external and the second with an internal thread;

- in the design of the predominantly threaded part, a special lock is provided, which ensures the continuity of the connection;

- on one of the structural elements of the package, a serial number will be applied;

- if necessary, the hollow cylinder is made with ribs of a certain configuration that will converge with similar ribs on the covers;

- the hollow cylinder is made with a small cone in length.

Depending on the configuration and dimensions of the product in height, the product is packaged, either in two caps, or in two caps and one or more cylinders, which are interconnected using a threaded connection. Using the lock on the threaded part, the reliability of the connection of the packaging structure during transportation of goods and the disposability of the packaging in order to protect the manufacturer’s trademark are ensured.

The serial number is applied in order to protect the manufacturer’s trademark, it can always be used to determine how, when and from whom, the packaging got to the manufacturer of the goods, and the goods went to the distribution network. Ribs are also provided to protect the manufacturer’s trademark. For applying the manufacturer’s trademark and serial number, decoration technology is used. The cone on the cylinder is provided for the purpose of transport efficiency during package transportation.

To solve the problems of productivity and economic feasibility in the production of universal packaging, it is proposed to use the mold shown in the drawing.

A special mechanism is provided in the mold, which ensures the production on a single mold of a number of standard sizes of hollow cylinders and caps in diameter (for example, from ⌀ 30 mm to ⌀ 100 mm), etc. with fast replacement of working parts (matrixes). It consists of a fixed housing 1, four sliding carriages 2, fixing pins, stabilizing springs, adjusting studs 3 and nuts 4.

The principle of operation is as follows.

After loosening the nut clamp 4, the pins are unscrewed, the installed matrix 5 is replaced with a matrix of a different diameter in diameter, then the pins are screwed fully and the nuts are clamped 4. The diameter range obtained on one product mold depends on the amount of free play of the carriages 2 .

The basic technology for the manufacture of structural elements of plastic packaging provides for the molding of plastic hollow products by blow molding.

Thus, there is a place to be:

- a universal plastic design for individual packaging of various (regardless of configuration and dimensions) piece goods of mass demand, which has a wider range of qualities than cardboard packaging and allows for a higher degree of protection for the brand of the manufacturer of goods;

- productive manufacturing technology (the productivity of one machine reaches over 20 thousand pieces per hour), capable of using the small production to meet the demand of any market for such packaging with a very effective economic result;

- universal (which significantly reduces the cost of the product) equipment.
