Description

DK 172771 B1

The present invention relates to a discharge spout for containers for particularly viscous liquids and of the kind specified in the preamble of claim 1. Such liquids may be oil or oil consistency similar to products such as / syrup / paint / juice / soap / rinse agent or the piglets, hereinafter called liquid leaving the can / bottle / bucket / container, hereinafter called container.

The spout, according to the invention, is the solution to a very old problem that everyone encounters from time to time.

When a thick or sticky liquid has to leave a container, the mass will not release the container, it will naturally follow the mouth and run along the underside, much to the annoyance of the user. This makes it almost impossible to empty drip-free. If the liquid is oil, the oil follows the container's mouth, makes a surge during emptying due to the adhesive effect and puts a good amount of oil into the screw cap thread on the container.

When the lid is later screwed on, the remaining oil will spread over the can and form an oily membrane.

Many solutions have seen the light of day to improve this situation in the form of funnels, extension tubes and more. The spout according to the invention can be designed as part of a normal outlet spout / spout or as an accessory unit in connection with screw cap / plug 20 or as cardboard / foil / metal, hereinafter called foil, which is applied to the outlet hole in the container and ensures that discharge is effected. , without wasting or running problems.

The problem with the spout according to WO 92/22466 and NO 117573, when a thicker liquid liquid leaves their outlet nozzle is not poured precisely so that a funnel 25 similar object may be needed. After pouring, these spouts cannot end without spillage as viscous liquids require an interface to prevent fluid collection and spillage.

This invention grabs where the problem is, namely where the liquid comes out.

The invention is based on long-term research on fluid surface bending on the thicker sticky fluids, as well as the small but significant impact of the capillary effect.

These drawbacks are avoided by forming the spout referred to in the preamble of claim 1 as set forth in the characterizing part of the claim.

The invention is explained in the following FIG. more particularly in connection with detailed drawings showing the embodiment of the spout according to the invention: in DK 172771 B1

FIG. 1 The drawing shows here a container in which the spout is made of the foil type, you can clearly see the locking system, coming from inside the container and only passage out of the container is above the 3-point platform B-C-D, which is located lower than the top of A.

FIG. 1 a The drawing is a line drawing illustrating the operation of the spout with letters. 1

FIG. 2 The drawing shows the spout as seen from the side built into the container's construction, again the system finally closes with the 3-point platform B-C-D, which is here withdrawn so that attachment of the lid is possible without confrontation of the 3-point platform.

FIG. 3 The drawing shows details such as FIG. 2, however, with support F of the 3-point ice platform.

FIG. 4 The drawing here shows the spout built into screw, plug, closure lid as an accessory part G that is screwed or applied to existing containers.

FIG. 5 The drawing shows the spout in foil form, could be of the disposable type used in existing containers.

FIG. 6 The drawing shows FIG. 5, a little more from the front, which clearly shows the structure of the foil type.

The sides A make sure to guide the liquid out of the container. A is designed as a side support (Fig. 1) whose task is to advance the liquid to B whether the discharge is slow or high speed. A protrudes farther from the container than B, in the vertical position.

30

Edge B is the place where the liquid leaves the container and is passed onto the 3-point platform consisting of B-C-D.

The sides C are responsible for directing the liquid towards the center. Sticky liquid follows the 35 sides so that the liquid is brought in towards the center point D, even at high flow.

The tip D, together with C, has the task of adjusting the flow of liquid around the point D, the liquid always distributes 50-50 around D, this means that the liquid flow can easily fall below 1 m.m. without the liquid starting to wave or cling in the 40 downward direction.

2 DK 172771 B1

Point A-B-C-D is of great importance here, since the sides (C) direct the liquid to the center, besides point D, this causes the center of the liquid to always be in point D, regardless of the speed of fluid flow. If the 3-point platform is facing down (see fig.

2,3,4,5 & 6), all the liquid will pass through A over B which is directed to the center of the sides 5 C to point D. When the liquid flow is decreasing to almost zero, B will give a break point on the liquid between The 3-point platform and the canister's interior and liquid which are in the canister return and on the 3-point platform a liquid depot is built on the surface between BCD, whose liquid surface size depends on the viscosity and temperature of the liquid. Any excess liquid can now leave the platform only from point D, since this point is the lowest point in the 3-point platform.

This causes the last excess drip to leave point D, whereupon the remainder of the liquid deposit remains on the B-C-D platform, where it is locked by its own surface tension. The fluid has now found and adjusted the crack point itself, and no liquid leaves the crack point D before the platform becomes overcrowded again.

The centering above point D causes that regardless of fluid thickness and fluid quantity, the center of the fluid is always at point D, so that a precise discharge to another container or opening is always vertical below.

The structure can be carried out in many ways, for example: In a container opening (Figs. 2 & 3), whether it is round or angular, the invention can be incorporated / molded as part of the opening, without disturbing the closure / opening of the container.

In a container opening built in conjunction with a screw cap closure mechanism cover, (Fig · 4) 25 In a container opening, inserted and made in foil. (Figs. 5 & 6) 3

Claims (2)

1. Discharge nozzle, for containers for especially viscous liquids and arranged for placement in the outlet opening of the container, the discharge nozzle being a piece of suitable resilient flexible sheet material, for example plastic foil or cardboard, and adapted to be inserted into the outlet opening during use. built-in as an integral part of the container on the inside of the outlet opening of the container or in a part of the container for screwing or self-locking fixed application on the outlet opening of the container, in particular existing container opening, to enable 10 drip-free discharge of liquid from the said container, disposed in the outlet opening has a closed or substantially closed cylindrical shape, such as a predominantly tubular outlet nozzle with a cut-off platform for the fluid flow, characterized in that the cut-off platform is formed as a triangle or triangle-like pin, the baseline of which forms a part of the upper free edge of the ice tubular studs, and whose vertex, when the bounce is in the vertical position, extends downwardly relative to the baseline outside the wall of the stud, so that the vertex lies below the baseline and where the upper free edge of the stud extends smoothly downwardly into the vertical or substantially substantially horizontal baseline of the stud in the stud, such that the stud is located below the upper portion of the stud 20, whose lateral surface or surfaces extend over the stud and in use form outer walls of the liquid for outlet above the stud baseline.
