Embodiment Construction

[0035] return figure 1 , a package 10 for a fillable food product is provided. Package 10 includes a polymeric opening portion 30 adapted to receive lid 11 . exist figure 1 In, the package is depicted as a substantially rectangular paperboard-based package further comprising a layered structure of aluminum foil, however, as will be appreciated by those skilled in the art, the package is not necessarily limited to this material or shape.

[0036] Advantageously, as figure 2 and 3 As shown, the opening portion 30 includes a threaded element 32 adapted to receive the cap 11 in a sealing manner. In order to further ensure the seal, said threaded element 32 is also suitable for elastic connection with the annular retaining element 13 of the cap 11 .

[0037] Further reference to the figure 2 and 3 , the package 10 includes a polymeric opening portion 30 . The polymer opening portion 30 may be formed from a polymer composition comprising any of HDPE, LDPE, LLDPE, or a blen...

Abstract

A package for a fillable food product and a method for molding a polymeric opening portion onto a packaging sheet are provided. The package (10) includes an opening portion (30) formed from a polymer composition, the opening portion (30) including a weakened feature (31) having a thickness of less than 200 microns and having a thickness greater than that of the opening portion (30) compared to said weakening feature (31). ) directly adjacent parts are thinner. The polymer composition comprises sodium sulfite particles having the following size characteristics: (i) 0% have a size greater than 75 microns; and (ii) have an average size of less than 25 microns.

Description

technical field [0001] The present invention relates generally to a package for a fillable food product, and in particular to a package for a fillable food product having an opening portion made of a polymer composition having weakened features, the polymer composition Contains sodium sulfite granules. [0002] The present invention also relates to a package for a fillable food product having an opening portion containing sodium sulfite particles and a package container body. Background technique [0003] Different types of opening means provided on packaging containers (e.g. containers formed of packaging sheet and adapted to contain substances such as food, especially for liquid beverages such as juice, water, milk, wine, etc.) is known. [0004] One such opening means comprises a hole or a thinned portion in a wall portion of the packaging container and a plastics material opening means connected to the wall portion and covering the hole in a closed state. The opening ...
