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 ).

1 . A container with a reservoir to collect a product; a dispensing device connected to the reservoir, wherein the dispensing device has an opening to dispense said product; a connection between the dispensing device and the container; as well as a device to hold back excessively large particles of said product, so that these particles cannot reach the opening of the dispensing device, and so that the opening cannot become clogged, wherein the device is fixed into position using a mount between the reservoir and the dispensing device, and the device has a multiplicity of passages, which enable the passage of smaller particles of said product through the opening, wherein the diameter of said passages is from about 0.5 mm to about 5 mm and is less than or equal to the diameter of said opening. 
   
   
       2 . The container according to  claim 1 , wherein said dispensing device has a spout that can be attached or screwed onto said container. 
   
   
       3 . The container according to  claim 1 , wherein said device is mounted at a connection between said container and a mounting ring of said dispensing device. 
   
   
       4 . The container according to  claim 3 , wherein a circumferential connection area of said device is clamped between said mounting ring and the upper end of a container neck. 
   
   
       5 . The container according to  claim 1 , wherein a centre part of said device is free of said passage. 
   
   
       6 . The container according to  claim 1 , wherein a recess is provided in said device and that this recess extends down towards the reservoir. 
   
   
       7 . The container according to  claim 6 , wherein said recess forms a platform, which is connected to the edge of the device via a circumferential flank and an annular connection area. 
   
   
       8 . The container according to  claim 1 , wherein circular passages with a certain diameter as well as slot-shaped passages with a certain length and width are recessed in said device. 
   
   
       9 . The container according to  claim 8  wherein only slot-shaped passages are provided in the flank. 
   
   
       10 . The container according to any of  claims 1 , wherein said device comprises from 3 to 150 passages ( 19 ). 
   
   
       11 . The container according to  claim 1 , wherein said passage has a diameter or a minimum width of from about 1.0 to about 4.0 mm. 
   
   
       12 . The container according to  claim 11 , wherein at least 80% of said passages have a diameter or minimum width of about 1.2 mm to about 3.5 mm 
   
   
       13 . A kit for creating hair bundle effects comprising at least one container according to  claim 1  and at least one product which is a hair treatment composition selected from the group consisting of highlighting compositions, dyeing compositions, styling compositions, perming compositions and combinations thereof. 
   
   
       14 . The kit according to  claims 13 , wherein the kit further comprises one or more marking tools for marking and separating a hair bundle from the remaining hair. 
   
   
       15 . The kit according to  claims 13 , wherein the kit further comprises an applicator for applying the hair treatment composition to the hair, wherein the applicator is selected from the group consisting of comb applicators, brush applicators, wand-like applicators, two-parts movably joined applicators and combinations thereof.
