Abstract

FIELD: chemical industry, construction, food industry.

SUBSTANCE: invention relates to devices for metering multicomponent liquid or paste-like materials. Proposed device contains first metering cylinder with hole to let out component, first piston and first rod installed inside cylinder, and also additional cylinder with pistons and rods and holes to let out component installed concentrically relative to first cylinder. Areas of cross section of cylinders are inter related proportionally to relation of components included into mixture. Rods are interconnected.

EFFECT: simple design, provision of reliable storage of components.

Description

The invention can be applied in various industries: chemical, construction, food industry, and relates specifically to devices for dispensing multicomponent, liquid or pasty substances. The device can be used, for example, for separate storage and mixing of epoxy adhesive components.

Known packaging for bulk food products according to the application of the Russian Federation No. 98116566, IPC 7 B 65 D 33/36, publ. 06/27/2000. Packaging for bulk products is made of paper, polymer or similar flexible material in the form of a bag or bag, closed at both ends, in which to extract contents from the volume filled by it, in the transition region between one of the closed ends of the bag and the bordering with it a narrow side wall, the user can form a discharge hole. A feature of the device is that in the area lying essentially diagonally opposite the discharge opening of the other of the closed ends of the bag, a holding device is also provided of flexible material, which is usually located inside the outer contour of the package, but which, when the contents are removed, can be pulled out of the package by its part forming the handle.

The disadvantage of this package is its low strength due to the use of unreliable materials. The packaging is disposable and not suitable for storing liquids.

Known packaging (container) according to the application of the Russian Federation for invention No. 97105401, IPC 6 B 65 D 88/16, made of rigid material containing a bottom, a side wall of a cylindrical shape and an open top.

Disadvantages: during prolonged storage, the product may be saturated with moisture, during transport it may spill out of the open top. In addition, the package is designed to store only one component and is not suitable for dosing.

Known fluid dispenser A.S. USSR No. 1185094, IPC 4 G 01 F 11/00, which contains a housing, a removable tip of which is communicated through an output capillary channel with a working chamber, in which a plunger is placed along the axis of the housing, spring-loaded to its travel limiter and provided with a drive made in the form of a rod with a push button and its movement stops, which differs in that a telescopic pusher is introduced in it in the form of two bushings, the contact surfaces of which are made with a step, and in the radial channel of the inner sleeve made on its part with with a smaller diameter, at least one ball is arranged to move along the radial channel, and an annular groove for the ball is made in the rod. The telescopic pusher is worn on the stem with a part with a smaller diameter.

The disadvantage of the dispenser is that it is applicable for microdoses of the liquid component and is not suitable for dispensing multicomponent substances.

Known dispenser for A. St. USSR No. 821928, IPC 3 G 01 F 11/06 (prototype), which contains one cylinder, piston and rod mounted inside the cylinder and an outlet at the end.

Disadvantage: the device can be used to dispense only one component.

Objectives of the invention: simplifying the design, providing storage, supply and dosing of multicomponent liquid or pasty substances.

The solution to these problems was achieved due to the fact that the dispenser for multicomponent mixtures containing a main cylinder with an outlet for the exit of the component, inside which a piston and a rod are installed, differs in that the dispenser contains at least one additional cylinder mounted parallel to the main in which a piston and a rod are also installed, and the cross-sectional areas of the cylinders are proportional to each other in proportion to the ratio of the components included in the finished mixture, and to synchronize the feed components of the mixture rods and cylinders are interconnected. Cylinders can be made in a common housing. Cylinders and pistons can be made concentric, in this case, drainage holes are necessary in the connecting device. Cylinders can also be made of transparent material and contain scales. The dispenser can be equipped with a removable plug and equipped with a removable mixer mounted on the common end of the cylinders in which the outlet openings are made.

The invention is illustrated in the drawings, where:

figure 1 shows the device in the transport position,

figure 2 shows a view of BB

figure 3 shows the tip 12.

The dispenser (figure 1 ... 3) contains a cylinder 1, a piston 2, a rod 3 and at least one additional cylinder 4, an additional piston 5 and an additional rod 6. The rods 3 and 6 are interconnected by a connecting device 7. At the common end “A”, the exhaust holes “B” and “C” are made. Under the pistons 2 and 5, cavities “G” and “D” are formed, filled with components. The device is equipped with a removable plug 10 mounted, for example, on the thread 11, and can be equipped with a mixer 12.

Scale 9 is applied on one or all cylinders 1 and 4, provided that they are made of a transparent material, such as polystyrene.

In the initial position, the cavities “G” and “D” are filled with components that are necessary to obtain the mixture. From the end “A” remove the removable plug 10 and install the mixer 12 (Fig.3). Applying force to the connecting device 7, squeeze out the components from the cavities “G” and “D” through the holes “B” and “C” into the mixer 12, where they are mixed. On a scale of 9, you can accurately meter the mixture and determine the amount of unspent components.

The use of the invention made it possible to accurately dose several separate components for the separate storage of multicomponent mixtures.

Claims (1)
