    • 专利摘要:
    A dispensing valve, particularly adapted for a squeeze bottle containing a viscous product, has a valve head in the form of a thin flat wafer of small diameter stationarily supported as freely as possible from obstructions, and above it an elastically deflectable diaphragm having a central opening with a periphery that seats on the periphery of the wafer. Internal pressure causes the diaphragm to move slightly from the wafer during a dispensing operation.

    专利说明:

    The invention relates to containers and packaging, namely, to valves for elastic tubes opened by the action of the material, extruded from the tube. A valve is known for: tubes, containing a cap, on the end surface of which a channel is formed for placing in the last fitting a single plug, which is made from a length for the passage of material l3. The disadvantage of the valve is that canes can become clogged with scrap. In addition, part of the material when closing the valve remains between the cap and the stopper, which reduces the reliability and performance of the valve, the closest to the technical essence and available: this result to the proposed is a valve for tubes containing a cap with a central hole and a stopper connected to the cap to close the opening. Moreover, the tube has the shape of a truncated cone 2. A disadvantage of the known valve is that the material sticks to the surface of the tube as it leaves the tube, and the layer of material increases during operation. The purpose of the invention is to improve the reliability by preventing sticking of material on the valve. This goal is achieved by having a tube for the tube with a central hole and a plug for closing the hole, wall, cap around the hole, which has a bevel and plug made in the form of a disk, the side wall is made bevelled to mate with the beveled wall of the cap, while in the cap is formed a hole for the passage of air. , FIG. 1 shows valve tube, vertical section; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2.. The valve for tubes consists of a threaded 1 and an end 2 parts and has a side wall on which an annular shoulder 3 is made to be placed in the annular groove of the threaded part. The end wall is inclined to the horizontal at an angle of Zr15. The cap has a central hole 4. The wall of the cap along the perimeter of the hole has a bevel and is inclined to the horizontal at an angle of 3-15. Inside the cap is mounted a cork made in the form of a disk 5, the side wall of which is made obliquely to mate with the beveled wall of the cap. The disk 5 is connected by means of radial inclined plates b with the threaded part 1 of the cap. Plas. Tina b also serve to limit the movement of the tube into the interior of the tube. The end part 2 of the cap plays the role of a membrane, i.e. bends under the action of material extruded from the tube, forming an annular; the gap between the cork and beveled st.en. There is a hole 7 in the cap for the passage of air. The angle of the cap wall as well as the side wall of the plug is 45 °, and the thickness of the disk 5 is about 0.38 mm. It is advisable that the diameter of the disk 5 does not exceed one third of the diameter of the front part 2 of the cap. The valve operates as follows. The threaded portion 1 of the cap is attached to a tube (not shown). When the elastic tube is compressed, the material in it rises and presses on the front part-2 of the cap, which bends and rises upwards relative to the disk 5. At the same time, through the opening 4, the material comes in the required amount from the tube. When the tube is released, the end part 2 is lowered, the bevelled surfaces of the cap and disk walls are connected, excluding any material ingress between them, and the delivery of the material stops. The image will make it possible to reliably dispense material from the tube and close the latter
