Abstract

ABSTRACT OF THE DISCLOSURE:
The invention relates to a composite dispenser for materials in paste form which are intended to be admixed with a diluent prior to use, comprising a flexible container consi-sting of a lower material-containing section and of an upper section forming an open receptacle when separated from said lower section by a perforable wall whereby, after perforation, application of pressure upon the lower section will cause a controlled quantity of the material contained therein to be dispensed through said perforation into the upper receptacle for admixture in situ with a suitable diluent.

Description

~` :
4~ 9 The present invention relates to a dispense~ for material~ in paste form, such as concentrated water-colors or oil-colors, whiGh are intended to be admixed with a suitable diluent prior to use~
As is well known, water-colors and oil-colors are usually sold in concentrated form and small quantities are taken from the container for use and admixed with a suitable solvent.
The containers commonly used are plastic or metallic squeeze tubes.
Thé problem with such containers is that, since the actual admixture must take place in a separate vessel, numerous vessels must be acquired, one for each color used. Furthermore, this operation results in a waste of material due to the inability of the user to control with accuracy the amount of ;-concentrate dispensed. ;
The present invention relates to a dispenser for materials in paste form which permit an extremely accurate dis-pensing of said material into an open cup which forms an integral ; part of the dispenser and in which the admixture with the suitable diluent can be effected.
More specifically, the dispenser of the invention com-,i prises an outer wall, an inner cup-shaped portion open at its ; upper end and made of flexible and deformable material, a substantially flat annular zone surrounding the cup-shaped portion and located at its upper edge, and an annular lip which surrounds '.!
the annular zone and extends generally upwardly from the outer 1~ edge of the zone. The outer wall, cup portion, annular lip and 1, annular zone are all interconnected~ A substantially flat closure member is disposed oVer and is bonded to the upper sur- ;
face of the annular zone thereby to close the cup-shaped portion ;
' and define, with the annular lip, an open top receptacle. In this manner, the closure member may be puncture to allow dispensing '' ~ :
" _ _ , ' , ' -4~
of the material contained within the cup~shaped portion into the ; open receptacle when pressuxe is applied to the cup-shaped portion.
Preferably~ the outer wall and the cup-shaped portion ,~
are frustoconical.
In one embodiment, the closure member is composed of two coextensive engaging layers, a first layer havin~ an opening preformed therein, and a second disposed above the first layer and free of openings.
In another embodiment, the closure member is composed of first layer having an opening preformed therein and a second layer disposed above the first layer which covers only a portion of the first layer but covers completely the preformed opening.
In a still further embodiment, the closure member is ~, composed of a unitary section having a hollow upwardly extending portion integral therewith, this portion being frangible to ~r ~. ;, allow dispensing of the contents.
. .
Embodiments of the invention will now be described with reference to the appended drawings wherein:
Figure 1 is a sectional view of the dispenser of the invention shown fully assembled.
., Figures 2 and 3 are sectional views of other embodi-ments of the means of closings operable in the present invention. -~-The main body of the present dispenser has externally an approximately cylindrical or slightly frustoconical shape. `
Said-body is formed from flexible, easily deformable material ~7'', '' of suitable thicknesses, such as plastic, plastified material or the like. On the upper part of the said body the external wa~
is bent inwardly and downwardly for a depth of few millimeters 30 so as to form the sides 3 of a shallow cup; said wall then ;-~
. , continues without interruption to form a flat annular zone 5. At the center of said annular zone there is formed a central cavity L~
; ~ - 2 -~ ' 4~9 7 which extends downwardly within the interior o~ the external wall 1. This cavit~ constitutes the actual material-containing section of the dispenser and can be of a cylindrical, hemispheri-cal or other suitable shape. The upper or closure part of the container consists of a disk 9 of a diameter slightly smaller than ~.
the internal diameter of the sides 3 of the cup; the disk is formed of rigid or semirigid plastic material of the same chemical composition than that of the main body, or of a plastified heat-~ sealable cardboard, or of a heat-sealable aluminium, or of any ~ 10 other material which can be sealed by heat or by chemical or physical means to the .~,, .:i , :1 .

1~)4~49 flat snnular zone 5 of the ma$n body.
To utilize the di~pensqr of the present invention, one fir~t fills the central cavity 7 with t~e desired material and then seal~ said cavity by means of disk 9, along the flat an~
nular zone 5. The disk t~us effects an air-tight seal for the container, the contents of whlch remain protected from drying, contamination and the like.
In the embodiment shown in ~igure 1, disk 9 iB compoEed of two layers of egual diametQrs, a first layer 11 having preformed therein an opening 1~ of suitable size and shape and a second layer 15 integral therewith~ thinner than ~aid first layer and ~ithout any openingq.
;.. . .
To use the product, it is sufficient to pierce the second layer 15 in correæpondence to opening 13 by means of . ., :,J a suitable ob~ect, such as a penci~ point. To dispense the material, pressure is applied on the lower section of container 7 forcing the desired quantity of material through opening ,;
13 into the cup defined by the sides 3 and t~e disk 9. The ;J paste material can then be diluted or otherwise treated.
;l Arter use~ the treated material remsining in the cup~
, ,, particularly ~hen ~uch material i8 concentrated oil-paint or water-paint, tends to dry thus forming a film which recloses the opening and effectivelg prevents air from coming into ~; contact ~ith the material still remaining in the container, ,~,~j .
;~ thus preventing it from drying and ~o protecting it. If the i materials being dispensed do not possess such filmforming charQcteristics~ a suitable plug msy be provided to close the i opening.
Pigure~ 2 and 3 sho~ the other embodiments of the means . ~

`; In Figure 2, dis~ 9 i8 provided with a removable adhesive ~ tab 17 which serve~ to close opening 13 preformed in said disk.

1~ 4 ~ ~9 In figure 3, disk 9 is pro~ided with a hollow upwardly-e~tending sect$on 19 ~hich can be cut prior to u~e to obtaini the de3ired opening.
It i~ noted that, for aesthetic purpose3, particularly ~: ~here the dispen~er i8 used to market paint~, the di~k cani be formed totally or partially of a transparent material. This allows the pro~pective purchaser to view the precise color of the contents, adding marketing value to the present devlce.
