Abstract
A method of producing a container, such as a flip-top cigarette packet, is disclosed. The method includes the initial step of folding an elongate blank at a fold line so that first and second portions of the blank on respective opposite sides of the fold line are brought into mutually facing relationship, and the subsequent steps of folding the first such portion to form the main body of the container and folding the second such portion to form the lid of the container, the latter folding step being carried out whilst the lid portion remains hingedly connected with the main body at the fold line. Also disclosed is apparatus comprising respective folding means to perform the three folding operations referred to above.
Claims19
A method of producing a container from a foldable container blank having a fold line at the boundary between a first longitudinal portion of said blank and a second longitudinal portion of said blank, the method comprising:
- a. the initial step of folding said blank at said fold line to bring mutually adjacent surface portions of said first portion and of said second portion respectively into mutually facing relationship;
- and
- b. the step of gripping said mutually adjacent surface portions in said mutually facing relationship whilst carrying out the further steps subsequent to initial step of folding said first portion to form exclusively from said first portion a main body of said container, and folding said second portion to form a lid of said container while said lid remains hingedly connected with said main body at said fold line.
Apparatus for producing a container provided with a lid from an elongate blank of foldable material, the apparatus comprising, in combination:
- first folding means to fold said blank at a fold line to bring mutually adjacent surface portions of a first portion of said blank and of a second portion of said blank respectively into mutually facing relationship;
- gripping means to grip said mutually adjacent surface portions in said mutually facing relationship;
- second folding means to fold said first portion to form exclusively from said first portion the main body of said container during the operation of said gripping means;
- and
- third folding means to fold said second portion to form the lid of said container during the operation of said gripping means.
