Problems solved by technology

[0004] In the initially mentioned ingredient-dispensing device, the way in which the quantity of product outflow is controlled must take into account a disadvantage which can make the device unsuitable for dispensing small and extremely small doses
On the other hand, the above-mentioned second device is practically usable only for the minimum amount of transfer

Embodiment Construction

[0023] Figure 1a The ingredient-dispensing element 10 according to the invention is shown in plan view. Through the circular inlet opening 11 at the top here, the middle part of the outlet opening 21 can be seen, which is partly defined by the conical bell-shaped peripheral wall 22 of the ingredient dispensing element 10 (cf. figure 2 ) to cover. The discharge openings 21 are aligned along the major axis of the oval or oval region 20 . exist Figure 1a The slit-shaped outlet opening 21 in the illustrated embodiment is designed as a cutout in the oval surface area 20 such that it divides almost the entire oval area 20 . The oval region 20 remains uncut only around the circumference.

[0024] When the ingredient dispensing element 10 in this first figure is not compressed at the circumferential point 12 of the oval surface area 20, the oval shape of the surface area 20 of the ingredient dispensing element 10 on the opposite side of the inlet opening 11 becomes very obvious....

Abstract

The invention relates to a metering element (10) for flowable and bulk materials, in a deformable, in particular elastic basic body, having a round inlet opening (11) and a slot-shaped outlet (21). On the side which lies opposite the inlet opening (11), an oval face (20) is provided, in which the slot-shaped outlet (21) is oriented in the longitudinal axis of the oval face (20). The outlet (21) can be widened in a variable manner by lateral pressure on circumferential points (12) in the region of the longitudinal axis of the oval face (20). The metering element (10) is preferably attached as a frustoconical connecting sleeve between containers and / or lines, in particular hoses.

Description

technical field [0001] The invention relates to a dosage-dispensing element having the features stated in the preamble of claim 1 . Background technique [0002] In the manufacture and use of free-flowing, pourable bulk materials such as in agriculture, the building materials industry or in the chemical industry, materials are often transferred from hoppers or large containers to small containers or taken out for use or sent to another location. For the removal of defined quantities, for example for weighing out equal quantities of product, it is particularly important to be able to control the discharge of the product from the container as accurately as possible. In high-volume processing, material flow is often regulated by simple sliding doors, but this can often result in uncontrolled transfer of material during opening or closing of the hopper. Such an ingredient dispensing device with a slide-controlled discharge opening is described, for example, in CH681881A5. [...
