Packaging for multi-component compositions

Abstract

Exemplary embodiments of disclosure relate to packaging for separately storing, and subsequently mixing, multiple components. The packaging includes a container formed from a first wall and an opposing second wall, wherein a closure splits this container in a leak-proof manner, into a first chamber and a second chamber within said container. The closure is formed from a closure piece arranged on the first wall and a closure counterpiece arranged on the opposing second wall, one part of a spatula forming this closure piece or closure counterpiece. Such a spatula can separate the two chambers from one another as part of the closure system, is always available, and cannot be lost. Furthermore, as a result of its shape, it can be used to mix and administer the contents of the chambers, and to process/apply the mixed multi-component composition.

What is claimed is: 
     
         1 . Packaging for separately storing and subsequently mixing several components, the packaging comprising:
 a container formed from a first wall and an opposing second wall; and   a closure that splits the container, in a leak-proof manner, into a first chamber and a second chamber within the container,   wherein the closure is formed from a closure piece arranged on the first wall, and a closure counter piece arranged on the opposing second wall, and   wherein one part of a spatula forms the closure piece or the closure counter piece.   
     
     
         2 . The packaging according to  claim 1 , wherein the closure is a snap connector with interlocking counter pieces, in which the closure piece is an interlocking receptacle element and the closure counter piece is an interlocking snap-in element. 
     
     
         3 . The packaging according to  claim 2 , wherein the closure piece is an interlocking receptacle element of substantially semicircular cross section and the closure counter piece is an interlocking snap-in element of substantially semicircular cross section. 
     
     
         4 . The packaging according to  claim 2 , wherein the one part of a spatula forms the closure counter piece. 
     
     
         5 . The packaging according to  claim 3 , wherein the one part of a spatula forms the closure counter piece. 
     
     
         6 . The packaging according to  claim 1 , wherein the spatula consists of a thermoplastic plastic selected from the group including: high-density polyethylene (HDPE), medium-density polyethylene (MDPE), low-density polyethylene (LDPE), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC), polyamide (PA), ethylene-vinyl acetate (EVA), chlorosulfonated polyethylene and thermoplastic polyolefins (TPO). 
     
     
         7 . The packaging according to  claim 1 , wherein the spatula is curved over less than an entire transverse direction. 
     
     
         8 . The packaging according to  claim 1 , wherein a first component is located in the first chamber and a second component is located in the second chamber, wherein the first component and the second component can react chemically with one another. 
     
     
         9 . The packaging according to  claim 8 , wherein at least one of the first component and the second component is a pasty substance. 
     
     
         10 . The Packaging according to  claim 8 , wherein the first and second components include at least one of adhesive compositions and sealant compositions. 
     
     
         11 . The packaging according to  claim 8 , wherein a ratio of a volume of the second component to a volume of the first component is 1:1-1:10. 
     
     
         12 . The packaging according to  claim 11 , wherein a ratio of a volume of the second component to a volume of the first component is 1:2-1:5. 
     
     
         13 . The packaging according to  claim 12 , wherein a ratio of a volume of the second component to a volume of the first component is 1:2-1:3. 
     
     
         14 . A method for applying a multi-component composition using a packaging having a container formed from a first wall and an opposing second wall; and a closure that splits the container, in a leak-proof manner, into a first chamber and a second chamber within the container, wherein the closure is formed from a closure piece arranged on the first wall, and a closure counter piece arranged on the opposing second wall, and wherein one part of a spatula forms the closure piece or the closure counter piece, the method comprising:
 a) opening the closure and thus combining contents of the first chamber with those of the second chamber within the container;   b) mixing the contents of the first chamber with those of the second chamber using the one part of the spatula which forms the closure piece or the closure counter piece, without the container being opened; and   c) applying the mixed contents of the first chamber and the second chamber with the aid of the spatula.   
     
     
         15 . The method according to  claim 14 , wherein in step b) the contents of the first chamber and the contents of the second chamber are moved in a longitudinal direction from one end of the container to another end of the container, wherein the movement with the aid of the part of the spatula which forms the closure piece or the closure counter piece is performed by pressing the first wall against the opposing second wall while simultaneously moving in the longitudinal direction of the container. 
     
     
         16 . The method according to  claim 15 , wherein movement of the content of the first chamber and the content of the second chamber in the longitudinal direction from one end of the container to the other end of the container is performed 4-8 times. 
     
     
         17 . The method according to  claim 15 , wherein after the content of the first chamber and the content of the second chamber have been moved in the longitudinal direction from one end of the container to the other end of the container, a part of the container that is substantially free of the contents of the first chamber and the contents of the second chamber is rolled up, and then a part of the container that contains substantially the contents of the first chamber and the contents of the second chamber is kneaded manually. 
     
     
         18 . The method according to  claim 15 , wherein after the content of the first chamber and the content of the second chamber have been moved in the longitudinal direction from one end of the container to the other end of the container, a part of the container that is substantially free of the contents of the first chamber and the contents of the second chamber is rolled up, and then a part of the container that contains substantially the contents of the first chamber and the contents of the second chamber is kneaded manually.
