Packaging for freezer pops containing at least one active agent

Abstract

A packaging in the form of a freezer pop for storing a freezable liquid the packaging includes a sealed chamber for storing the freezable liquid formed from at least one inner layer having a sealable edge portion composed of a sealable material and sealed at the edge portion; at least one outer layer composed of a tear and puncture resistant material having an outside surface; at least one intermediate layer which is in sealable contact with both the at least one inner and outer layers, such that all layers are sealable together to form the sealed chamber; and at least one moisture barrier layer in proximity to the outer layer for at least substantially preventing moisture from escaping the sealed chamber for an extended period of time.

Description

[0001] The present invention relates to packaging for active agent-containing freezer pops, and more particularly to a moisture barrier-containing packaging for freezer pops containing an active agent which needs protection against moisture loss, such as a pharmaceutical, which substantially reduces or eliminates moisture loss in the packaged product. BACKGROUND OF THE INVENTION [0002] Frozen ice products including “snowballs”, Italian ices, freezer pops and frozen fruit juices have long been popular treats among consumers especially during the warmer weather months. Frozen ice products of this type can be carried on sticks, in plastic tubes, or in wax coated paper containers. No utensils or plates are necessary. One popular frozen ice product in particular is the freezer pop, which has been a staple of summer treats for many years. The freezer pop can be purchased and consumed in either as a chilled liquid or as a frozen product. The freezer pop is simple and convenient to store an...

Benefits of technology

[0007] The present invention relates generally to packaging for storing a freezable liquid containing an active agent so that the active agent may be administered through a freezer pop. The packaging of the present invention includes an arrangement of film layers including a moisture barrier, which substantially reduces or eliminates undesirable moisture loss, thereby enhancing the quality and storage life of the freezable liquid. In addition, the packaging of the present invention is designed to resist tears and punctures for enhanced child-proof safety.

[0012] at least one moisture barrier layer in proximity to the outer layer for at least substantially preventing moisture from escaping the sealed chamber for an extended period of time.

Problems solved by technology

Typically, the packaging film used for conventional freezer pops is fairly pervious to moisture, which can result in significant moisture loss over an extended period of time.

However, the packaging used to house freezer pops containing such active agents has been found to be inadequate.

This is because conventional packaging allows excessive moisture loss over an extended period of time, and current laws regulating typical active agents such as pharmaceuticals generally require a shelf life of two years.

The amount of moisture loss typically encountered in current packaging is considered unacceptable for freezer pops which contain controlled amounts and concentrations of active agents.

Such moisture loss can adversely affect the taste, ingredient balance, consistency, quality perception, and efficacy of the product.
