PKG 315: Paperboard Design & Molded Plastic Bottle Design

i hate this class

Blank

A flat sheet size from which a carton is cut

Area

The used space on the blank

How do you calculate scrap?

Blank - Area

Style

Refers to the method of folding (e.g. reverse tuck end (RTE), straight tuck end (STE))

Estimation Specification

Approximates the number and layout of the area covered on the blank

Shows nesting on the press sheet

Helps determine the amount of waste

Total Rule

The linear measurement of all cutting and scoring blades

Production Specs

Used to determine die and order the paper for run

Number on

The total number of cartons on a paper sheet

Tolerances

Allow for small differences in measurements that occur during manufacturing

Width

Side to side as the bottle sits on the shelf

Depth

Front to back as the bottle sits on the shelf

Height

Top to bottom as the bottle sits on the shelf

Have to take the closure into account when determining for the overall packaging

How are bottles viewed?

Front, bottom, isometric (3D on a 2D surface), sectional, side (right side, left side), top

Finishes

Letter and number code referring to the diameter and thread designation

E.g.: M28SP400 —> M28 = 28 mm diameter, SP400 = thread designation

400 finish

1 thread turn

410 finish

1.5 thread turns

415 finish

2 thread turns, tall “H” dimension

425 finish

2 thread turns, narrow threads

430 finish

Buttress finish: thick threads and a top bead

Better seal, more application torque

2000 finish

Lug finish: non-continuous threads

T Dimension

The outside diameter of the thread

E Dimension

The outside diameter of the neck

I Dimension

The inner diameter of the bottle neck

S Dimension

Measured from the top of the finish to the top edge of the first thread

Determines the orientation of the closure to the bottle and the amount of thread engagement between the bottle and cap

H Dimension

The height of the neck finish

Thread Depth

(E-T)/2

Standard finish criteria

Thread turns, distance between threads, height, top beads, and continuous vs non-continuous threads

Neck Rings

Ensure the safety and strength of products; have different finishes —> use different styles of closures

Total bottle height

Bottle height (not including the finish) + finish H dimension + base of neck (BON) to H dimension

Fill point capacity

Up to the shoulder area

Overflow capacity

Up to the very top (the brim); helps manufacturers determine which bottles can fit certain products
