Problems solved by technology

[0008] Since the sealing member keeps sliding relative to the outlet during the whole stroke, the disadvantages existing in the prior art can be overcome, especially the disadvantage that the outlet cannot be sealed airtightly due to paint accumulation

Embodiment Construction

[0012] As mentioned above, the subject lid 1 of the present invention is designed to close jugs or other containers for liquid or granular products. This precision cap 1 has an outlet 5 provided with a sliding seal 2 acted upon by a hairpin spring 4 . The movement of the seal 2 is controlled by a pivoted opening lever 3 . Additional means are located between the outlet and the lever to create the pressure of the spring 4, thus making it possible to bend and twist said spring. Thus, with the same spring 4, the double action of the pressure of the sliding spring 2 and the self-closing is obtained. The combination of twisting and bending thrust of the spring by manual operation of the lever ensures both a progressive resistance to opening the sliding seal for optimum precision control over the opening area, and a quick release of the lever by fully releasing the lever Closure, at the same time, exerts a minimum constant pressure on the sliding seal to ensure an overall good sea...

Abstract

The invention relates to a precision cover (1) comprising a pour spout (5), which is used to close a container housing a liquid or a particulate product, of the type in which the top of the cover forms a pour spout (5) which is equipped with a spring-loaded (4) sliding lid (2), the movement of which is controlled by a pivoting opening lever (3). The inventive cover (1) is characterised in that the pivoting opening lever (3) controls at least two different operating modes for the sliding lid (2), namely: one mode in which, when the control lever (3) is subjected to a given angular movement, the lid (2) is moved by a small amount in relation to the opening in the pour spout (5); and another mode in which, when the control lever (3) is subjected to the same angular movement, the sliding lid (2) is moved by a larger amount in relation to the opening in the pour spout (5), such that the user can dose the flow from the container with very high precision.

Description

technical field [0001] The present invention relates to precision caps with outlets for closing containers for liquid or granular products. [0002] More particularly, the present invention relates to a precision cap with an outlet, wherein the top of the cap forms the outlet with a sliding seal on which a spring acts, the movement of which is controlled by a pivoting opening lever. Background technique [0003] Such a closure cap simultaneously performs the functions of a precision metering cap and a seal cap. In certain applications, especially when these caps are used to close paint buckets, it must be possible to quickly and completely seal the cap outlet so that the paint does not evaporate or dry out. In order to obtain accurate metering, during opening of the cap outlet, preferably, there is a certain stroke reduction ratio, ie the lever moves a long stroke and the seal of the outlet moves a short stroke. However, if the stroke the lever moves remains proportional t...
