THUẬT NGỮ BAO BÌ - TERMINOLOGY


Thuật ngữ/từ chuyên môn (terminology) là cần thiết, được dùng trong nghiên cứu, trong hội thảo, thảo luận chuyên đề; được dùng chỉ sản phẩm, mô tả các lỗi trên sản phẩm, các thành phần của sản phẩm như thiết bị, vật tư, bao bì … hay các chi tiết liên quan. Thuật ngữ được cấu tạo, gọi hay đặt tên theo cách cấu trúc, theo đặc điểm hoặc theo công dụng …

+Three Piece Can Bodies - Soldered Side Seam




Body - May vary in shape, body beads may be present, and is constructed of electrolytic tinplate (ETP).



Body Bead - Ridges or rib-like indentations on the can body located singly or in clusters on the general body area to provide resistance to lateral abuse (denting).



Flange - The outward flared edge of the can body that becomes the body hook of the double seam.



Lap - The short length of the side seam adjacent to each end where the side seam is reduced to two overlapping layers of metal plate bonded by solder.



Notch - The small cut-away portion of the body blank in the lap area which will reduce the amount of material in the area where a double seam will be formed.



Side Seam - The joint connecting two edges of the body blank (a piece of metal plate cut to individual can size). Along most of its length this joint consists of four tightly interlocked and soldered layers of metal plate (side seam fold). For a short distance adjacent to each end (lap areas) the side seam is only two layers thick.




Side Seam Enamel Margin (inside) - These are narrow strips of uncoated metal plate along the inside edges of an inside coated body blank that will form the side seam. The margins must be present, as organic coatings in either margin will preclude complete soldering of the side seam.



Side Seam Enamel Margin (outside) - These are narrow strips of uncoated metal plate (approximately 1 cm wide) along the outside edges of an outside coated body blank that will form the side seam. The margins must be present, as organic coatings in either margin will preclude complete soldering of the side seam.



Side Seam Indent - A small dent usually located at each end of the side seam fold. It strengthens the side seam, minimizes side seam bow and controls the cylinder length at the side seam.



Side Seam Vent - An opening in the side seam fold which allows the gases formed during soldering to escape and permits solder to flow into the folds.








+Three Piece Can Bodies - Welded Side Seam

Body - Similar to soldered three piece cans, welded can bodies may vary in shape, body beads may be present and they are constructed of either electrolytic tinplate (ETP) or tin free steel (TFS).



Side Seam - The lap joint formed when connecting the two edges of the body blank. The two edges overlap by approximately 0.5 mm. After welding, the thickness of the welded seam is approximately 1.2 times the thickness of the body plate.






+Two Piece Can Bodies

Body - Similar to three piece cans, the body may vary in shape and material used. The body consists of an integral end and a body wall formed from a single piece of metal plate and the top edge of the wall has a flange.



Body Bead - A side bead (alternate terms: stack, abuse, or chime bead) may be present near the bottom of the body wall to provide resistance to lateral abuse (denting), assistance in stacking and the same mobility (rolling) characteristic as a double seam provides to a three piece can. Other beads may also be present to provide lateral abuse resistance.



Bottom Profile - This term describes the contoured shape of the cross section of an integral end.



Countersink - This may or may not be present on integral end. Primarily used to provide strength to the integral end.



Panels - Raised or depressed surfaces of the integral end which provide strength or alter the container capacity. Step panels are the angular surfaces joining other panels (centre, first, second, outer, middle, etc. - see Fig. 2.3.a.)



Reinforcement Features - A series of rings, ridges or parallel lines pressed into the metal of any part of the can body or integral end. These features provide the metal with additional strength to withstand the stresses of retorting and handling.
