Plastic container with reinforced panel

Abstract

The invention relates to a plastic recipient comprising a panel with at least one radius of curvature greater than 100 mm, where the panel has reinforcing means. The reinforcing means includes a peripheral slot defining a reinforcing contour and a plurality of inner slots arranged inside the reinforcing contour. Each inner slot has two ends, where each end opens out into the peripheral slot, or at least one end opens out into another inner slot.

1 . A recipient ( 1 ) made of plastic material comprising a panel ( 14 ) with at least one radius of curvature greater than 100 mm, the panel ( 14 ) having reinforcing means ( 16 ), wherein the reinforcing means ( 16 ) include:
 a peripheral slot ( 160 ) defining a reinforcing contour, and   a plurality of inner slots ( 161 ;  162 ) arranged inside the reinforcing contour, each inner slot ( 161 ;  162 ) having two ends ( 161   a ;  161   b ;  162   a ;  162   b ), each end opening into the peripheral slot ( 160 ), or at least one end ( 162   a ;  162   b ) opening out into another inner slot ( 161 ).   
     
     
         2 . The plastic recipient ( 1 ) as claimed in  claim 1 , wherein a peripheral slot ( 160 ) defines a closed reinforcing contour. 
     
     
         3 . The plastic recipient ( 1 ) as claimed in  claim 1 , wherein the peripheral slot ( 160 ) defines an open reinforcing contour. 
     
     
         4 . The plastic recipient ( 1 ) as claimed in  claim 1 , wherein the inner slots ( 161 ;  162 ) are arranged to form a lattice pattern. 
     
     
         5 . The plastic recipient ( 1 ) as claimed in  claim 1 , wherein the inner slots ( 161 ;  162 ) are rectilinear. 
     
     
         6 . The plastic recipient ( 1 ) as claimed in  claim 1 , wherein the inner slots ( 161 ;  162 ) are curvilinear. 
     
     
         7 . The plastic recipient ( 1 ) as claimed in  claim 1 , wherein the inner slots ( 161 ;  162 ) include:
 a first series (S 1 ) of inner slots ( 161 ) that are parallel with one another and oriented in a first direction (A) at an angle to a longitudinal axis (X) of the recipient ( 1 ), and/or   a second series (S 2 ) of inner slots ( 162 ) that are parallel with one another and oriented in a second direction (B) also at an angle to a longitudinal axis (X) of the recipient ( 1 ).   
     
     
         8 . The plastic recipient ( 1 ) as claimed in  claim 7 , further comprising at least two additional inner slots ( 164 ) extending substantially along the longitudinal axis (X) of the recipient ( 1 ). 
     
     
         9 . The plastic recipient ( 1 ) as claimed in  claim 1 , wherein the depth (PRP) of the peripheral slot ( 160 ) is between 0.3 mm and 1.5 mm. 
     
     
         10 . The plastic recipient ( 1 ) as claimed in  claim 1 , wherein the depth (PRI) of each inner slot ( 161 ;  162 ) is between 0.3 mm and 1.5 mm. 
     
     
         11 . The plastic recipient ( 1 ) as claimed in  claim 1 , wherein the ratio (PRP/PRI) of the reinforcing means ( 16 ) is between 0.8 and 2.4, where:
 (PRP): depth of the peripheral slot ( 160 ), and/or   (PRI): depth of the inner slots ( 161 ;  162 ).   
     
     
         12 . The plastic recipient ( 1 ) as claimed in  claim 1 , wherein the width of the peripheral slot ( 160 ) is between 100% and 300% of the depth (PRP) thereof, and preferably 200% of the depth (PRP) thereof. 
     
     
         13 . The plastic recipient ( 1 ) as claimed in  claim 1 , wherein the width of each inner slot ( 161 ;  162 ;  164 ) is between 100% and 300% of the depth (PRI) thereof, and preferably 200% of the depth (PRI) thereof. 
     
     
         14 . The plastic recipient ( 1 ) as claimed in  claim 4 , wherein the lattice pattern defines a plurality of full surfaces ( 17 ), each of which is delimited by four inner-slot portions ( 161 ;  162 ), each full surface ( 17 ) having an area of between 150 mm 2  and 1000 mm 2 . 
     
     
         15 . The plastic recipient ( 1 ) as claimed in  claim 14 , characterized in that the ratio between the areas of two adjoining full surfaces ( 17 ) is between 0.5 and 1.5. 
     
     
         16 . The plastic recipient ( 1 ) as claimed in further comprising a label ( 15 ) covering the panel ( 14 ), the reinforcing means ( 16 ) extending over a surface covering between 55% and 90% of the surface of the label ( 15 ).
