Case having wrapping material cutting function

Abstract

The present invention relates to a case having a wrapping material cutting function. For this purpose, there is disclosed a case having a wrapping material cutting function, in which a body (51) includes a front panel (57), a bottom panel (65), a back panel (64), a cover (58), and a plurality of side panels, wherein the body (51) is made of a synthetic resin material, and wherein cutting protrusions (52) are kept spaced apart from each other and successively formed to protrude upward by connection portions (53) along a bend line, i.e., a bend line between the front panel (57) constituting part of the body (51) and an adjacent inward bend portion (56), so that a wrapping material accommodated in the body (51) is cut off by the cutting protrusions (52) protruding upward along the bend line.

1 . A case having a wrapping material cutting function, in which a body ( 51 ) comprises a front panel ( 57 ), a bottom panel ( 65 ), a back panel ( 64 ), a cover ( 58 ), and a plurality of side panels, wherein the body ( 51 ) is made of a synthetic resin material, and wherein cutting protrusions ( 52 ) are kept spaced apart from each other and successively formed to protrude upward by connection portions ( 53 ) along a bend line, i.e., a bend line between the front panel ( 57 ) constituting part of the body ( 51 ) and an adjacent inward bend portion ( 56 ), so that a wrapping material accommodated in the body ( 51 ) is cut off by the cutting protrusions ( 52 ) protruding upward along the bend line. 
     
     
         2 . The case of  claim 1 , wherein one surface of each of the cutting protrusions ( 52 ) is formed in a shape of a vertical surface ( 52   a ), and a remaining surface of each of the cutting protrusions ( 52 ) is formed in a shape of an inclined surface ( 52   b ) inclined at an angle in a range from 30 to 40°. 
     
     
         3 . The case of  claim 1 , wherein a protruding height of the cutting protrusions ( 52 ) ranges from 1.5 to 2.0 mm. 
     
     
         4 . The case of  claim 1 , wherein a material of the body ( 51 ) is PP or PET, and a thickness of the body ( 51 ) ranges from 0.4 to 0.45 mm. 
     
     
         5 . The case of  claim 1 , wherein accommodation spaces ( 67   a  and  67   b ) are formed in the cover ( 58 ) and the inward bend portion ( 56 ), and a moving portion ( 68 ) configured to be movable within a range of the accommodation spaces ( 67   a  and  67   b ) is formed in the front panel ( 57 ). 
     
     
         6 . The case of  claim 1 , wherein a downward bend portion ( 56   a ) is further formed in the inward bend portion ( 56 ). 
     
     
         7 . The case of  claim 1 , wherein a first side panel ( 59 ) having first and second auxiliary side panels ( 60  and  61 ) is formed on each of both sides of the front panel ( 57 ) and the back panel ( 60 ) constituting part of the body ( 51 ), a stop hole ( 59   a ) is formed in the first side panel ( 59 ), second side panels ( 62 ) each having a third auxiliary side panel ( 66 ) are formed in the inward bend portion ( 56 ) in connection with which the stop protrusions ( 52 ) are formed along the bend line between the inward bend portion ( 56 ) and the front panel ( 57 ), an embossing protrusion ( 66   a ) is formed on each of the third auxiliary side panel ( 66 ), and a fastening panel ( 63 ) having an elastic portion ( 63   a ) configured to be fitted into the stop hole ( 59   a ) is formed at each of both ends of the cover ( 58 ), so that lower ends of the first auxiliary side panels ( 60 ) are caught and supported on the embossing protrusions ( 66   a ) and the elastic portions ( 63   a ) of the fastening panels ( 63 ) are fitted into the stop hole ( 59   a ) of the first side panel ( 59 ). 
     
     
         8 . The case of  claim 2 , wherein accommodation spaces ( 67   a  and  67   b ) are formed in the cover ( 58 ) and the inward bend portion ( 56 ), and a moving portion ( 68 ) configured to be movable within a range of the accommodation spaces ( 67   a  and  67   b ) is formed in the front panel ( 57 ). 
     
     
         9 . The case of  claim 3 , wherein accommodation spaces ( 67   a  and  67   b ) are formed in the cover ( 58 ) and the inward bend portion ( 56 ), and a moving portion ( 68 ) configured to be movable within a range of the accommodation spaces ( 67   a  and  67   b ) is formed in the front panel ( 57 ). 
     
     
         10 . The case of  claim 4 , wherein accommodation spaces ( 67   a  and  67   b ) are formed in the cover ( 58 ) and the inward bend portion ( 56 ), and a moving portion ( 68 ) configured to be movable within a range of the accommodation spaces ( 67   a  and  67   b ) is formed in the front panel ( 57 ).
