Tea bag package

Abstract

A tea bag package that includes a triangular envelope having first and second opposite flaps connected to each other along first and second sides of the triangle but not along the third side and furthermore having a third flap connected at the third side to the first flap and via a folding line foldable between a first position in which the third side is open and a second position in which the third side is closed so that the three flaps together define a closed chamber. The tea bag package includes a tea bag disposed in the chamber and a string attached to a corner of this tea bag and running through a slit or eye in the point in which the two closed sides join each other. The string has a length allowing the tea bag to exit the envelope via the third side when the third flap is in first position. The free end of the string is anchored in an anchor tab connected to one of the closed sides on the first flap via a perforated folding line extending up to or nearly up to the point in which the closed sides of the triangle join each other. The anchor tab is folded in over the second flap and detachably joined to a section on this by means of a weak adhesive. The tea bag is easy and convenient to use and does not soil the surroundings after use.

1 . A tea bag package comprising: 
 a triangular envelope having first and second opposite flaps connected to each other along first and second sides of the sides of the triangle and defining a chamber,    a tea bag disposed in the chamber, and    a string attached to a corner of the tea bag and running through an opening at a triangle point opposite the third side of the triangle and having a length allowing the tea bag to exit the envelope via the third side when it is open,    wherein the free end of the string is anchored in an anchor tab connected to the first flap at one of the sides of the triangle via a folding line extending up to or towards the point in which the closed sides of the triangle join each other, and    the anchor tab is folded over the second flap and is detachably joined to this flap.    
     
     
         2 . The tea bag package of  claim 1  wherein the folding line is perforated and the anchor tab is detachably joined to the second flap by joining means.  
     
     
         3 . The tea bag package of  claim 2  wherein the first and second opposite flaps are not connected along the third side of the triangle, and the triangular envelope comprises a third flap connected to the first flap at the third side and is foldable via a first folding line between a first position in which the third side is open and a second position in which the third side is closed.  
     
     
         4 . The tea bag package of  claim 3  wherein a free portion of the third flap is detachably connected to the joining means on the second flap in the second position.  
     
     
         5 . The tea bag package of  claim 4  wherein a flap is formed in an area at the joining means on the second flap for detachably receiving the free end of the third flap in the second position.  
     
     
         6 . The tea bag package of  claim 5  wherein the flap is formed by cutting through the material of the second flap along a curve.  
     
     
         7 . The tea bag package of  claim 6  wherein the curve extends along a curved line with the concave side facing the opening.  
     
     
         8 . The tea bag package of  claim 6  wherein the curve has the shape of a circular arc and that the flap is connected to the second flap along a chord of the circular arc.  
     
     
         9 . The tea bag package of  claim 8  wherein the point of the third flap is cut off along a line essentially coinciding with the chord of the circular arc when the third flap is in the second position.  
     
     
         10 . The tea bag package of  claim 3  wherein at least one of the folding lines is a double line.  
     
     
         11 . The tea bag package of  claim 1  wherein the triangle is an equilateral triangle.  
     
     
         12 . The tea bag package of  claim 1  wherein the first and second of the closed sides of the triangle are closed by second and third folding lines respectively and further comprising a longitudinal fixing tab located along the third folding line and being joined to the second flap, with the anchor tab forming a triangle that is essentially congruent with the triangle formed by the envelope.  
     
     
         13 . The tea bag package of  claim 12  wherein the first flap is formed with at least one transverse folding line extending from at least an area at the point in which the closed sides join each other and in a direction crosswise to the first folding line and continuing into the third flap, and that the second flap is formed with at least one second transverse folding line extending at least from an area at the point in which the sides of the triangle join each other and in a direction crosswise to the opposite side.  
     
     
         14 . The tea bag package of  claim 13  wherein the at least one first and second transverse folding lines respectively are bent into the envelope.  
     
     
         15 . The tea bag package of  claim 3  wherein the spacing at least along a central area between the side on the second flap located at the first side of the triangle and the opposite triangle point is smaller than the spacing between the first folding line and the triangle point.
