Tried and True Bottles & Closures
Color-coded and
child-resistant closures find their match with bottles in various sizes and
styles.
Closure Systems
A company’s standard program provides a variety of individual packaging
solutions by using various container and closure combinations. Emphasis is geared
toward safety, protection of sensitive contents, and intelligent, user-friendly
packaging systems. A variety of functional features, such as tamper evidence,
child resistance, and highly active adsorption agents to obtain desired moisture
contents, are available either as a combination or as single components. Sanner
of America Inc., Cherry Hill, NJ; 856/988-6465; www.sanner-usa.com.
Child-Resistant Closures
A child-resistant closure consists of a steel undercap with a polypropylene
transparent overcap. The steel barrier properties of the closure, coupled with
the company’s lithographic capabilities, provide a functional, marketable
package, according to the company. Closures can be color-coordinated to the
product, making them both appealing to the eye and easier for seniors to identify
the correct bottle. Sizes include 24, 28, 33, 28, and 45 mm, all 400 finishes.
Lining systems include heat induction and pressure sensitive. Penn-Wheeling
Closure, Glen Dale, WV; 800/999-2567; www.penn-wheeling.com.
Pharmaceutical Rounds
 |
A line of thick-wall HDPE pharmaceutical rounds is available in 100-, 180-, and 270-ml sizes. The containers have a minimum wall thickness of 0.050 in., more than double the thickness of standard bottles, according to the company. USP testing proves a significant reduction in moisture permeability with these bottles, thus increasing product shelf life. The thicker land area of the neck also provides additional surface contact for pressure-sensitive and heat-induction lining materials. The rounds are manufactured with a 38-400 neck finish with an “H” dimension, which accepts push down and turn child-resistant closures.

PET Oblongs
A new style of PET wide-mouth oblong is available in two sizes. The 225-ml and
40-ml oblong packers are suitable for nutritional supplements, vitamins, pain
relievers, and other forms of tablets and capsules sold over the counter. The
225-ml bottle features a 38-400 continuous-thread neck finish and the 40-ml
bottle has a 28-400 neck. The company can provide closures for the bottles.
Using existing platforms, the new bottle styles were built in response to customers
who wanted a flat label panel instead of the curved label area of traditional
round packers. The bottles’ rectangular base allows maximum label-panel
width for both sizes of wide-mouth oblongs. Alpha Packaging, St. Louis;
314/427-4300; www.alphap.com.
Nvision
Packaging bottles are constructed of a clear polypropylene copolymer resin that
meets elevated chemical-resistance standards. This allows for a high-quality
bottle that lets users see what’s inside without compromising the integrity
of the contents. The bottles are available with a breakthrough HDPE tamper-evident
closure system. It features a tear-away ring that stays on the bottle when the
cap is removed. Once closed, the bottle cannot be opened without leaving the
ring behind. Customers can order bottles with the proven leakproof company valve
seal, a lined closure, or a lined closure with a foil-induction seal, all with
the tamper-evident closure. Nalge Nunc International Corp., Rochester,
NY; 800/625-4327; www.nalgene.com.
