RU2723698C1 - Self-closing container at filling - Google Patents

Abstract

FIELD: package and storage.SUBSTANCE: invention relates to closing equipment related to automation of closing of a container filled with, for example, water to prevent active evaporation of liquid medium. Self-closing container comprises housing with neck for filling with liquid medium. Inside the container there is a float, which floats upwards as water or other liquid enters under it. Container has ribbons attached to float, their other ends rigidly attached to a ring of rubber or fabric or from other material, inside of which with low friction coefficient belt is passed or passed cord that is connected to ends of tapes. Cone-shaped shape of upper surface of float provides additional sealing of water or medium in vessel in case of not tight tightening of ring, which has inclined surface towards side of container center, thus protecting container filling container from evaporation.EFFECT: container ensures, without human participation, filling with water and self-closing at its filling.1 cl, 1 dwg

Description

The invention relates mainly to capping equipment associated with the automation of closing filled containers (for example, water), which prevents the active evaporation of a liquid medium. This type of device in the form of containers can be located in villages / towns or in forests where fires are possible and there is not enough water to extinguish fires. Moreover, such containers can be filled both by a person and without his participation due to the collection of rainwater in an autonomous mode.

Analysis of the cited and other similar patents showed that closing and opening of containers, as a rule, is carried out in manual mode (by a person), although there is also an automatic effect.

The purpose of the invention: to ensure, without human intervention, the filling of water in a container self-closing when it is filled to almost completely prevent evaporation of the collected medium.

The technical result is achieved by the fact that the tank filled with water gradually closes its neck automatically, until the filling space (opening) is completely closed.

Self-closing when filling with water (or another medium), the tank is shown in the figure, where it is indicated:

1 - ring in the form of a medium mesh; 2 - thrust ring; 3 - a rubber ring (or from any other hydrophobic material such as a tarpaulin) with a groove inside around its circumference; 4 - tape or string inside a rubber or tarpaulin ring; 5 - the ends of the tape or twine extending from position 3 to the outside of the ring for connection to the ribbons; 6 - cork (or from other similar material) float; 7 and 8 - tapes cross-connected with positions 5; 9 - the float in the lower position with an empty tank; 10 and 17 - points of attachment of tapes to the float; 11 and 16 - pulleys covered by tapes; 12 and 15 - pulley bearings; 13 and 14 - the housing in which the pulleys are located; 18 - the bottom of the tank.

Explanations A wire mesh in the upper part of the tank protects the contents from the entry of birds, knots, leaves, etc. The thrust ring is installed to increase the rigidity / strength of the tank / tank. A rubber ring or a fabric material that does not allow water to pass through has a large line (bent part), inside of which a ribbon / twine with a low coefficient of friction is passed with respect to the material inside which it is located, which guarantees the float to lower down with an empty container. The ring is strong, for example, glued with glue (or otherwise attached) at the point of contact with the walls of the container around its circumference. Tape or twine - durable from oil-benzo-water-resistant material. The ends of the tape / twine coming out of the ring (key 3) are then firmly connected to the ends of the ribbons 7 and 8, spatially arranged as a crosshair. Cork (or from another material floating in the water) float in an empty container is in it in the lower position, resting on the horizontal surfaces of the pulley supports. In the upper position, when filled with rain or man pouring water, it is in the upper position of the tank (indicated by a dotted line). Pulleys 16 are used for belts 7 and 8, which cover them. At the same time, the ends of the tapes are firmly attached to the float, the lateral dimensions of which allow water flowing into the tank to freely penetrate under the float, thereby lifting it up and gradually tightening / closing the neck of the opening self-closing when filling the tank. Finally, the inclined upper surfaces of the poses. 3 contribute to the drainage of water into the tank, and the cone-shaped upper part of the float provides safety sealing of the tank / tank with water from evaporation in case if for some reason the tightening of the tightening ring 3 did not happen completely.

In the lower part of the tank, any stationary standard device is placed (for example, a plug, valve, valve — not shown in the figure), through which, if necessary, the accumulated water is quickly taken.

In a stationary state in the tank, the float is located in its lower part (at the bottom), but not clinging to the bottom. The presence of intersecting tapes 7 and 8 on one side are fixed at the float with their ends, and connected at the other ends to a rubber / tarpaulin ring located in the upper part of the container for sealing from above.

The work of the proposed design does not require human participation, since a natural phenomenon is used to fill the tank - rain, although, of course, a person can fill the tank. If it is necessary to extinguish a fire, a person opens a closed hole in the lower part of the tank and takes the required amount of water (to replenish the fire extinguisher or to connect a pump with a hose / fire hose).

Thus, the practical utility and feasibility of the application is obvious.

Claims (1)

A container self-closing during filling, comprising a housing with a neck for filling with a liquid medium, characterized in that the container inside contains a float that floats upward as water or other liquid enters under it, while there are cross-linked tapes fixed to it and rigidly attached to their other ends to a rubber or fabric ring or other material, inside of which a tape or a string is passed with a low coefficient of friction, also connected to the ends of the tapes, moreover, the conical shape of the upper surface of the float provides additional sealing of the water or medium in the container in case of not quite tight ring tightening, having inclined surfaces to the side to the center of the tank, protecting the medium filling the tank from evaporation.
