Description

This invention relates to the field of chemical industry, namely to the design of containers intended for storage. Transportation and use of chemical reagents and various laboratory equipment in a ready-made form for the intended purpose.

A device for transporting, storing, and using chemical reagents for their intended purpose is known, which is a turntable for reagents of the CANTI design. It is made in the form of a transparent cap, the movable half of which serves as a door. Under the cap rotates on the axis of the three-disk spinner. At the bottom of the turntable there is a drawer for storing indicator papers. Droppers with reagents are placed in the nest of the turntables. On the same turntable, only without a cap and a crate, if necessary, additional flasks with reagents are placed.

0).

A disadvantage of this device is that it is not possible to logically place any other laboratory equipment other than bulk and liquid reagents in dropper bottles and indicator papers in this fan. It is almost impossible to attach all the necessary laboratory supplies from the inside or outside to the transparent cap, for example - test tubes, pipettes, crucibles, porcelain cups, a spirit lamp and other items that provide an exhaustive analysis. If the listed equipment is attempted to be placed in the said turntable, then the use of such laying is extremely difficult, since there is no convenience for its movement, reliable fixing of glass equipment for which it is almost impossible to foresee

full-time jobs for its placement. In this case, glass laboratory objects hinder the review of reagents and are extremely time consuming and difficult to find for use in current work np; i analysis. The rotating transparent cap possesses resistance and insufficient strength, especially when transported under field conditions, which in certain cases leads to its combat and loss of reagents necessary for analysis. The technological process of manufacturing a turntable is rather complicated and time-consuming, it provides for special technological equipment, and a transparent material for it is difficult to access is expensive. The spherical shape of the rotor is irrational, especially for field conditions, does not provide sufficient tightness of its internal space and reliable fixation of the vials with reagents.

The closest to the described invention to the technical essence and the achieved result is the boxer of the installation kit of the field chemical laboratory (PCL) (2), made of wood, consisting of a body and two side wings attached to it; Inside the box there is a table attached to a cardboard folder. In the stowed position, the box is covered with a case. Belts are attached to the back wall of the laboratory case for carrying it over the shoulders. When transferring the laboratory from the traveling position to the workplace, it is necessary to remove the cover from it, remove the gate plate from the slot between the doors, rotate them half a turn (180 °) and open the doors, placing them at a right angle to the case of the box. Then remove the table and strengthen it in the lower position. Depending on the nature of the work table can be strengthened and in the upper position.

The disadvantage of the described container is that its lid does not provide ease of handling the contents of the crate during operation, since it is inefficiently deployed when opened by the service personnel and it needs to use special painstaking techniques to find the inside. instruments or reagents. Since the side flaps perform the role of a lid and are inconveniently located for work, it is not possible for an analytical chemist to efficiently carry out an exhaustive detailed overview of the property stored inside, and therefore quickly find the necessary equipment. It happens inside

the body as well as the inside of the flaps due to the fact that one type of property is located on top of another, or next to it, a masquerade, co-located products or reagents. This significantly complicates the work of the service personnel, since the items necessary for the analysis are searched for a long time in the total mass of the contents of the kit with their unnecessary removal from the package. When reviewing the chemical reagents contained in the same type of bottles in the laboratory building, only closing stoppers are visible, which make it extremely difficult to recognize the desired chemical reagent. This significantly increases the consumption of time for finding the reagents and lengthens the time of analysis.

The aim of the invention is to improve the usability.

This goal is achieved by the fact that the box for laboratory supplies and chemical reagents consists of a rectangular case with shelves, side boxes connected to it, carrying handles, locks, a folding hollow prismatic cover covering the top and front part of the case, and the box is made in The type of inserts placed inside the body can be moved out through the end walls, and the shelves are installed in the front part of the body in steps to form a cavity in the body for housing boxes.

This box is characterized in that it is equipped with a hinged hollow prismatic lid covering the upper and front part of the case, the boxes are made in the form of inserts placed inside the case with the ability to move out through the end walls and the shelves are installed in the front part of the case for placement of boxes.

The invention is illustrated in the drawings, where in FIG. 1 shows a general view of the proposed box with recessed boxes and a closed lid; Fig 2, the box is shown in working condition without placing any accessories in it; in fig. 3 The box is shown in working condition with an example of the possible placement of chemical reagents and some samples of laboratory equipment in it; Fig. 4 shows the device structure schematically in rectangular projections. The proposed package consists of (figs. 1-4): case 1 with shelves 2 connected to two side ducts 3. The case is equipped with a handle 4 for carrying a drawer and two locks 5, and in jjepxneu of its part a prismatic cover 6 is movably fixed on the floor 6. Box 3 are made in the form of inserts placed in the transport position of the box inside the housing 1 with the possibility of moving them out through the end walls 7, and the shelves 2 are installed in the front part of the housing 1 in steps to form a cavity in it to accommodate the ducts 3.

A box for laboratory supplies and chemicals is used as follows. In the recesses of the shelves 2, there are placed bottles with chemical reagents so that the information label on them was available for viewing by the maintenance staff when viewed from the eyes of the contents box. Laboratory accessories are placed in their regular places in the lid of biv boxes 3, which are then pushed inside the housing 1 and fixed. The lid 6 is closed by lowering it from the top down and pressing it against the body 1 with the help of locks 5. Thus, the property is pledged for storage and prepared for transportation.

To use the property for analysis, open the lid 6 and lift it up from the bottom up by turning it to a vertical position. Next, the box 3 is pulled out of the housing 1. Thus, the box is brought into working condition, which allows us to fully achieve the ease of use of laboratory equipment and chemical reagents.

Comparative experimental data proving the positive effect of using this box for laboratory supplies and chemical reagents compared to the prototype are shown in Table. 1. As follows from it, when using this crate, there is a significant increase in the productivity of the analyst’s chemical

by accelerating the search for the necessary equipment, and the convenience of working with the proposed clerk in both field and stationary laboratories. This is accomplished by using a flip-open prismatic lid installed in the working position vertically, as well as shelves and ducts that ensure rational placement of the contents of the box, its maximum view and quick search in the total mass of objects by organs of vision. Everything listed in the aggregate leads to an increase in labor productivity when conducting analyzes by approximately 15–20% compared with the use of a box by the design of the prototype. At the same time, a significant expansion of the functional

capabilities and ergonomic indicators of this design in both field and stationary conditions of field laboratories. In addition, the proposed box for laboratory supplies and chemical reagents is simple in design, convenient and affordable to manufacture.
