SU580819A3 - Closure for vessels with paste-like substances - Google Patents

Description

The sealing plate according to FIG. 5-11; in fig. 14 — the shutter of FIG. 1 and 2, axonometrics; in fig. 15 - the shutter of FIG. 5-12.

The closure for vessels with pasty substances contains a cap ca 1 with an outlet 2, connected to it and a cylindrical bore channel 3 located inside the cap with a device for mounting the cap on a vessel (not shown) and a spring locking plate 4 which is mounted on the cap for closing outlet 2. The stretchable wall 5 facing the plate 4 is made of an elastic material, and the other longitudinal part 6 is made of a rigid material in one piece with the spring locking plate 4.

The cap is made predominantly by injection molding of plastic material (polyethylene), which, for a given thickness, has sufficient elasticity and stretch near the outlet 2.

At the lower end of the vessel through-passage 3, an internal thread 7 is made to screw the cap onto the vessel. Instead of thread 7, it is possible to use a bayonet joint, through which the passage channel 3 is connected to the through-hole of the outlet valve or pressure vessel (not shown).

The wall thickness of the passageway 3 depends on the elastic properties of the material used, as well as on the thickness of the stretchable part 5 and the rigid longitudinal part b of its wall, on the length of the outlet 2 and the viscosity of the product.

The upper end of the stretchable wall part 5 fits snugly against the opposite surface of the tongue 8 of the rigid longitudinal part 6 of the passageway 3.

The outlet 2 is made coaxially with the cap 1, a transverse partition 9 adjoins the lower part of the wall of the passageway 3, which is made in one piece with the wall 10 passing into the wall 11 to form a groove 12 between them, the width of which corresponds to the peripheral size of the recess 13 in the springs storing locking plate 4 (Fig. 1).

In the groove 12 there is a rigid part 14 of the spring locking plate 4, the thickness of which is made in accordance with the width of the groove. The rigid part 14 of the plate must be made of synthetic material, preferably Ultraform R der BASF. The elastic part 15 of the plate 4 is connected to the rigid part 14 with an inward displacement to form the outer shoulder 16, and the inner shoulder is displaced in the opposite direction. Instead of the shoulder 17 it is possible to perform the plate 4 with a smooth transition of one part to another. In this case, both parts 14 and 15 of the plate outside of the cap are located one to another at an angle ot (Fig. 4), which is slightly larger than the angle J3 when the plate 4 is inserted into the groove 12, so that the elastic part 15 of the plate is prestressed in the direction of the edge of the input holes, while at the same time the friction between the side walls of the rigid part of the plate 4 and the inner walls of the groove 12 is so reinforced that the plate cannot move or fall out of the groove with increasing pressure 5 on it in the direction of the outlet 2. At the same time, The elasticity of the elastic part 15 of the plate increases this prestressing .;

In addition, the voltage rises even more as the pressure inside the passage channel 3 increases, for example by hand pressure on the cap or by lowering the pressure cap on the moving part of the discharge valve of the pressure vessel. In this case, the pressurized contents of the vessel fall.

5 into the passage 3 and the pressure on the expanded wall part 5 rises. Under the action of this pressure, the stretchable part 5 of the wall is expanded, and the elastic part 15 of the plate 4 moves, and with it the rigid part 14 in the direction of the arrow 18

0 (FIG. 4) as long as the increased pressure inside the passage channel 3 is maintained.

The surface of the tongue 8 is concave (see Figs. 5 and 6), and the surface of the wall portion 6 is convex, thereby increasing the tightness when closing the outlet and improving the removal of the extruded product.

The surface of the sponge 19 of the cap has a protrusion 20 (see Fig. 7), and the end surface

.. the jaws 21 of the plate are a cavity 22, into which the protrusion 20 enters when stretched, whereby an effective seal is achieved.

The extensible part 5 has a spike - 23 (see Fig. 8) on the outer surface facing the plate 4, which, when the product penetrates from the internal volume of the vessel into the passage channel 3, causes pressure on the plate 4, while the sponge 21 rises from the stretchable part 5, compressed against the surface of the sponge 19.

The closure for vessels is provided with two plugs 24 (see FIGS. 9-11) protruding downward from the jaw 21 and abutting in the locked position in the stops 25 (FIG. 9) of the wall of the passageway 3, while the plate 4 cannot be bent outward and the outlet 2 does not open even with strong pressure on the vessel.

The rigid part 14 of the plate with this shoulder 16 rests on the wall II of the recess 13. In the lower rigid part 14 of the plate on its inner surface a movement stop 26 is formed, which fits into the recess 27 of the wall 10. On the outer surface of the plate 4 there is a device 28 for supporting the arm for its movement, with which it is possible to translate the bolt into an unarranted position (Fig. 10). Wherein,

5, when the movement restriction 26 is in a position opposite the edge 29 of the recess 27, the plate 4 cannot exit the recess 13.

FIG. 12 shows the valve is not connected to the vessel, while the outlet 2

Claims (4)

open, and the groove 30 is formed between parallel spacers 31 and 32, the outlet 2 and the outer wall of the cap 1, and in the gap between the wall of the groove 30 and the last is placed a hard part 14 of the plate. The thickness of the spring locking plate 4 (Fig. 13) from the rigid part 14 decreases smoothly down to the jaw 21, whereby the plate acquires a heightened spring effect, and a minimum gap 33 is formed between the plate 4 and the notch 13 (Fig. 14 and 15) Plate 4 can be made of synthetic material or of steel grade or ordinary stainless steel. For countries with tropical climates, plate 4 should be made of heat-resistant plastic, such as polycarbonate. The described closure for vessels with pasty substances provides an increased tightness of the joint. Claim 1.
