    A collector device for collecting, metering and holding a small sample of liquid, e.g. a drop of blood taken from a finger prick, comprises a vessel (10, 11 or 10A, 52A) provided with an opening (20 or 20A) closed by a plug (22 or 22A), and a screwthreaded cap (15 or 15A) having a protruding spigot (30 or 30A) which, when the cap is screwed fully onto the vessel, enters the opening and pushes the plug down into the interior of the vessel. The plug is formed at its outer end with an outwardly facing recess (24), e.g. part- spherical, and the spigot is formed at its end which enters the opening with a tapering conical formation (31) adapted to enter the recess (24). In use, with the cap (15 or 15A) removed the recess (24) is filled with a quantity of liquid, the cap is then partly replaced to cause the spigot (30 or 30A) to abut the end of the plug (22 or 22A) so that its conical formation (31) enters the recess (24) and displaces excess liquid therefrom, trapping a metered sample of liquid of predetermined volume, less than the volume of the recess, in the space defined between the abutted ends of the plug and spigot. The cap (15 or 15A) is then screwed fully home causing the spigot to push the plug down until it falls into the vessel, thus transferring the metered liquid sample into the vessel whose opening (20 or 20A) is now closed by the spigot (30 or 30A). The device enables a metered quantity of blood to be collected and transferred into the closed vessel for subsequent analysis, without contamination of the exterior of the device by the blood, and without the use of delicate metering devices such as capillary tubes to meter the blood sample. A latch connection (55A, 59A) may be provided between the cap (15A) and a removable lid (52A) of the collection vessel whereby when the cap is unscrewed it slowly withdraws the lid and opens the vessel.

    The invention relates to collections for the placement, measurement and storage of a small amount of liquid and can be used in the collection of human blood samples for laboratory and Hbix analyzes. research and sampling microbiological cultures.
    The aim of the invention is to simplify the operation of the device by eliminating measurements of the amount of liquid in the sample and emptying the measuring device.
    FIG. Figure 1 shows a device for collecting and metering a liquid in a position in which the lid is partially screwed on and touches the stopper in the throat of the container, a longitudinal section; Fig. 2 - the same, before the start of work (the lid is in the upper position); in fig. 3 is a diagram of the interaction of the plug and the sleeve; FIG. 4 device with. fully screwed and plug, extruded bone in it, in fig. 5 shows an embodiment of a device with an external thread for accommodating a clamp before starting work, a longitudinal section, in FIG. In addition, with a fully screwed and plug, displaced into the container in FIG. 7 - cover, general view.
    The device contains a container 1 with a diluent neck 2, a metering device 3, a sleeve 4 and a stopper 5 mounted for movement in the neck 2 with a capacity 1 and cooperating with the sleeve 4 installed in the throat 4. The opposite ends of the stopper 5 and the sleeves 4 are provided with elements 6 and 7 for interacting with each other to form a cavity 8 of a predetermined volume with them.
    On the plug 5, the element 6 is made in the form of a hemisphere, and on the sleeve 4, the element 7 is in the form of a cone-shaped protrusion.
    The device can be equipped with a cover 9 with a thread 10 mounted on the neck 2 of the container 1 with the possibility of interaction with the sleeve 4, as well as a removable insert 11 and a locking connection 12 installed between the cover 9 and the insert 11. The container 1 serves to collect the liquid and can be It is made of rigid or semi-rigid plastic glass.
    In order to prevent the movement of the krush 9 down, the device may be
    provided with a removable intermediate washer 13 or removable intermediate disk 14 located inside the cover 9.
    Cork 5 is made with an annular collar 15.
    When using a device to collect a calibrated blood sample from a drop obtained from a prick of a person’s finger, the device is brought to the position shown in FIG. 2, The cover 9 is unscrewed and the washer 13 and / or disc 14 is removed. The required amount of blood is introduced into the element 6, made in the form of a hemisphere. Then, the 9 9 is wrapped around the neck 2.
    In this case, the sleeve 4 is lowered, displaces the excess amount of blood from the hemispheric element 6 until the elements 6 and 7 interact with the formation of the cavity 8 of a predetermined volume containing the calibrated amount of blood. The device takes the position shown in FIG. I.
    With long-distance screwing of the cover 9, the sleeve 4 pushes the stopper 5 down the neck 2. When the stopper 5 drops out, a calibrated amount of blood from the cavity 8 gets, together with the stopper 5, into the container 1, which is pre-filled with blood thinner. At this moment, the sleeve 4 itself seals the neck 2 instead of the stopper 5, preventing excess blood from entering the container. The stopper 5, being in the container 1, promotes mixing of the blood with the diluent, especially when the container 1 is shaken. until the insert i1 contacts the cover 9 and the lock connection 12 is activated. The container is closed - ready for transport.
    Performing a device for collecting and metering a liquid containing a sleeve and a plug installed with the possibility of rewinding in the container neck and communicating with the sleeve installed in the neck, supplying the opposite ends of the plug and sleeve with elements for interacting with each other to form a cavity of a predetermined 5 volume between them performance on the cork element in the form of a hemisphere, and on the sleeve in the form of a cone-shaped protrusion simplifies the operation of the device, providing
    the ability to dose sample and reduce the risk of air bubbles that interfere with the analysis.
    The supply of the device with a cap with a thread mounted on the container neck with the possibility of interaction with the sleeve ensures the tightness of the container, which is also convenient in operation.
     When performing a device with a removable insert and a locking connection installed between the lid and the insert, it is possible to smoothly open the cap, necessary to eliminate the loss of part of the sample.
