Description

Be s cli friction

The invention relates to a stand for sample vessels, in particular test tubes, with an elongated bottom area for / L'lage of the bottoms of the sample vessels and one above the Floor area arranged, with this connected holding area with through openings for the sample vessels.

Well-known stands of this type, which are widely used in chemical and clinical laboratories, as well as in the laboratories of doctor's offices are usually made of wood or plastic and should be cleaned at regular intervals, about contamination and thus possible falsification of experiments Avoid contamination, especially when working in clinical laboratories or in laboratories of medical practices will. In practice, however, such cleaning is extremely rare. In addition, it must be effective cleaning

! be made relatively carefully and is therefore

j very time consuming.

It is therefore an object of the invention to provide a simply constructed

To create a single-use stand that is so cheap that it can get through a new such stand can be replaced if a stand cleaning would have been required per se.

To solve this problem, a stand of the type mentioned is designed according to the invention by a one-piece, foldable blank, which has parallel fold lines delimiting the bottom area and its to the fold lines adjoining side parts at a distance from the floor area, complementary boundary surfaces for the formation of the through openings. The blank preferably consists of a deep-drawn plastic film, which for example is transparent or translucent, such as a thermoplastic film, preferably made of polyvinyl chloride or polystyrene.

The stand according to the invention thus consists of a one-piece Cutting that can be made very easily by punching and, if necessary, deep-drawing cheap sheet or plate material Can be produced and formed by the user before use by folding up and connecting the side parts to form a stand will. Since both the material and the manufacturing costs are relatively low, this stand is suitable as Disposable stand that does not need to be cleaned, but rather can be thrown away after soiling and replaced by a new stand formed from a blank.

There is a significant advantage in using transparent or translucent film as a cutting material in that the content of the specimen inserted in the rack

vessels can be viewed from the outside, so that in this way reaction processes, which are characterized by color changes, precipitates o.a. express, can be observed closely without the sample vessel (s) being removed from the stand would have to.

The transport costs for the blanks are relatively low, since the blanks pack themselves stacked on top of one another and have it transported.

Furthermore, the stand according to the invention is also suitable as a transport device for sample vessels in clinics, etc., where such sample vessels have to be brought from the wards to the laboratories and for which plastic odor paper cups are often used at the moment in which, however, no orderly and secure holding of the sample vessels is possible.

In order to achieve the most symmetrical structure possible for the blank, the parting plane of the through openings can be in the longitudinal direction when the side parts are folded up The central plane of the floor area is so that the boundary surfaces in each of the side parts each have one half limit a passage opening.

Between the boundary surfaces provided in the side parts adjacent through openings arranged contact surfaces

Chen cause a reliable positioning and alignment of the boundary surfaces to each other, so that the desired Through openings are formed. In some of these contact surfaces, which are connected to each other when the side panels are folded up come into contact, complementary locking elements, for example formed in one piece with the contact surfaces Projections and depressions are provided so that the two folded up side parts as a result of the engagement these locking elements are connected to one another and the blank in the position forming the stand keep.

To several similar, from inventive cuts To be able to connect existing stands to one another, complementary locking devices can be used on the outer surfaces of the side parts, about also projections and depressions are provided, so that a side part of a stand can be connected to the side part of another, similar stand and thereby a single stand with several rows of through openings is created.

For safe positioning of the inserted in the stand Sample vessels can be provided in the bottom area, aligned below the through openings, wells, which take up the bottoms of the sample vessels.

If the blank made of a deep-drawn plastic film, a thermoplastic film, for example, it is expedient to place the side panels perpendicular to the fold lines to form extending beads, which give the side parts additional strength, so that a stable Ständeraurfbau arises.

The invention is explained in more detail below with reference to the figures.

FIG. 1 shows a perspective illustration of two connected to one another, each produced from a blank Stand.

Figure 2 shows an end view of a stand according to the invention.

FIG. 3 shows a blank for producing a stand according to the invention in the partially folded state.

In FIG. 1, two interconnected stands, each made from a blank, are shown, each with a base area 2 and side parts 5, 6, which form .laltbereiche 7, 8 above the bottom areas, in which boundary areas to form the indicated through openings

for inserting the sample vessels, in this case test tubes, are provided. Below the holding areas are in the side parts vertically extending beads 31, the give the side parts greater strength, and there are also locking devices in this area of the side parts integrally formed, of which only the projections 35 can be seen in the side part 5, while corresponding depressions are in the side part 6 are located in which the projections 35 of the other stand corresponding projections are pushed / '. ckt, so as to to connect the two stands firmly together.

In Figures 2 and 3 is a blank and the end view, respectively a stand made from such a blank is shown, this blank and thus the stand thereby differs from the uprights according to FIG. 1 in that a smaller number of through-gany openings and beads are present is.

As shown, the blank shown in FIGS 1, a bottom area 2, in which recesses 37, 38, 39, 40 are formed and whose recess carries this recess Area is offset upwards from the border area. The longitudinal boundaries of the bottom area 2 are made by folding lines 3, 4 formed, to which side parts 5, 6 connect. These side parts are in their upper areas 7, 8,

So their holding areas, designed such that they on the one hand boundary surfaces 9, 11, 13, 15 and 10, 12, 14, 16 to Formation of the through openings and, on the other hand, of these boundary surfaces adjoining contact surfaces 17, 19, 21, 23, 25 or 18, 20, 22, 24, 26, which when the side parts are folded up 5, 6 lie against one another, so that the through-openings desired dimensions are formed. The contact surfaces

19 and 23 have depressions 27 and 29 and the contact surfaces

20 and 24 have corresponding projections 28 and 30, which when the side parts 5, 6 are folded up and are in contact with one another standing contact surfaces come into locking engagement with one another, so that the side parts in the folded-up position as indicated in FIG. Furthermore, in the side parts below the holding areas 7, 8 perpendicular to the fold lines 3, 4 extending beads 31, 32 are provided, which give the side parts additional strength.

Thus, when the side parts 5, 6 of the blank 1 around the fold lines 3, 4 folded upwards and the placement surfaces 17, 19, 21, 23 and 18, 20, 22, 24, 26 are brought to bear, results from the depressions 27, 29 and the projections 28, 30 a locking of the side panels in the folded-up position, and the resulting from the boundary surfaces 9, 11, 13, 15 and 10, 12, 14, 16 formed through openings lie
