Container with a device to prevent clogging of a dispensing device of the container

Abstract

For a container (1) with a reservoir (2) to collect a product (3) and a dispensing device (4), which is equipped with an opening (5) to dispense a flowable agent, particularly a powdery or granular product (3) dissolved and / or dispersed in a liquid (8), wherein said dispensing device is connected to the reservoir (2), a device (7) with passages (10) is used to hold back excessively large particles of the product (3), so that wholly undissolved product (3) and / or excessively large particles and / or poorly dispersed particles cannot reach the opening (5) of the dispensing device (4) and thereby cannot block the opening (5).To achieve secure protection of the opening against a blockage, it is proposed that the diameter (1) or the minimum width (12) of the passages (10) is from 0.5 mm to 5 mm and is less than or equal to the diameter (13) or the minimum width of the opening (5) (FIG. 7).

Description

FIELD OF THE INVENTION[0001]The object of the invention relates to a container to collect, mix, dissolve and or disperse a product as well as a dispensing of its flowable content with a device to prevent clogging of an opening of a dispensing device on the container.BACKGROUND OF THE INVENTION[0002]It is known that when a powder is dissolved or dispersed into a liquid clumps can form. Undissolved powder particles and / or clumps of poorly dispersed powder particles within the liquid can clog a dispensing device, if the opening is relatively narrow. As controlled dispensing from an opening is desired for some applications, openings with a small cross-section are used to prevent uncontrollable dispensing.[0003]The problem of clump formation during a mixing process can occur not just when dissolving and / or dispersing a powdery material into a liquid. It can also occur when dissolving and / or dispersing granular material into a liquid, when mixing two liquids together, or when mixing a pas...

AI Technical Summary

Benefits of technology

[0013]The device functions effectively and provides the maximum possible room in the container for the product to be dissolved / dispersed, along with the liquid in which the product is to be dissolved / dispersed, for the purpose of agitating the liquid to support the dissolving / dispersion processes if, similarly to Claim 3, the device is mounted at a connection point between the container and the mounting ring of the dispensing device.

[0014]If, according to Claim 4, there is a circumferential edge of the device clamped in between the mounting ring on the dispensing device and the upper end of a container neck, the device can be easily inserted into the container by placing it on the front of the container and then fixing it into position through placement of the dispensing device.

[0016]A particular advantage is achieved if, according to Claim 5, a centre part of the device, which is preferably circular, is free of any passage. The closed center part then protects the opening from the powder, granular material or cream to be dissolved / dispersed in a liquid during the shaking of the container to facilitate mixing. Whilst not wishing to be bound by theory, it is believed having a closed centre part can prevent the powder / granular / pasty material from becoming lodged within the opening during the shaking process. With a round container neck, a rotationally symmetrical dispensing device, or a round device to hold back particles, a closed center part on the device enables the protection of the opening in a secure manner.

[0017]To increase the passage surface and thus achieve less outflow resistance after the components have been mixed, it is advantageous, in a known manner, if a recess is provided in the device (Claim 6). For space considerations, it is helpful to extend this recess up to the reservoir, as is known from the prior art. To keep the recess from extending too far into the reservoir, it is advantageous if, according to Claim 7, the recess forms a platform that is connected to the edge of the device via a circumferential flank and an annular connection area. Based on the results obtained in experiments, it is helpful, depending on the case, if round passages with a certain diameter as well as slot-shaped passages with a certain length and width are recessed in the device (Claim 8). If only slot-shaped passages are provided in the flank (Claim 9), smaller particles that move somewhat parallel with respect to the flank can better pass through the passages.

Problems solved by technology

Undissolved powder particles and / or clumps of poorly dispersed powder particles within the liquid can clog a dispensing device, if the opening is relatively narrow.

The problem of clump formation during a mixing process can occur not just when dissolving and / or dispersing a powdery material into a liquid.

The problem of clump formation is especially prevalent for hair compositions which are created by mixing a liquid together with a powder and / or granular and / or pasty material, for example hair bleaching compositions.

In addition, there is a second problem that can arise for hair bleaching compositions.

The combination of clumps which can clog up the narrow opening, combined with a rapid evolution of gas by the product can lead to an increase in pressure within the container.

This makes the container hazardous to handle such hair compositions.

The known containers have the disadvantage that they have passages the diameter of which is either significantly greater or alternatively significantly smaller than the opening to be protected,

These approaches do not securely protect the opening from clogging when used with a hair composition created by mixing together a liquid with a powder / granular / pasty material, such as a hair bleaching composition.

The dispersed agglomerates of particles will either pass through the large passages of the device and clog the opening, or the dispersed particles will clog the narrow passages preventing the dispensing of product from the opening, or retain the particles on the device, thereby altering the nature of the mixed composition dispensed from that which is desired.
