Sorbent packaging

Abstract

In an elongated strip of desiccant packages each package includes a body formed from spun bonded non-woven polyethylene; a lateral seal at each end of the body, the seal comprising a knurled direct, adhesive free, seal having intersecting sealing lines each of which is arranged at an angle to the longitudinal axis of the package; a longitudinal seal extending between the lateral seals printed indicia on the package disposed substantially between the lateral seals, and spaced from the longitudinal seal, the longitudinal and lateral sealing areas being substantially free of printing; at least one registration mark on the body, the mark disposed at a known distance from at least one of the lateral seals, and outside of the sealing area; a sorbent material within the body.

Description

[0001] This application is a divisional application of an invention application, the invention name of the parent case is absorbent packaging bag, the application date is January 24, 2008, and the application number is 200880002952.x (International application number: PCT / US2008 / 051835 ). technical field [0002] The present invention relates generally to sorbent packages, and more particularly to packages of sorbents that are automatically inserted into a product (eg, a medicament). Background technique [0003] Adsorbents and desiccants in strips or bullet strips have been used by consumers for many years. Automatic high-speed machines and methods for manufacturing these products are relatively well known, and many companies offer these products to customers. While no specific minimum number of bags for each bullet strip has been developed, very large rolls of bags of up to 10,000 to 15,000 individual bags have been developed, suitable for automatic separation and inserti...

AI Technical Summary

Problems solved by technology

Arranging multiple transverse rows for the seal solves the problem of tearing, but introduces a weakening of the edge of the seal line closest to the contents of the bag, which in turn can lead to leaks

[0010] Another problem associated with the type of seal described is that although equipment has been developed for manufacturing the product and for separating and inserting the pouch into the consumer's product at a desired rate, The effect of accumulated tolerance errors in the manufacturing process can eventually lead to alignment errors in the installed equipment

[0012] Separation and insertion machines also suffer from accumulated errors

Although the machine is adjusted to separate the bags at the transverse seal area, accumulated errors may eventually result in the bags being cut outside of the transverse seal area, thereby releasing the contents of the pack, possibly contaminating the machine into which the pack was inserted. product and require the remainder of the bag string to be repositioned for subsequent separation and insertion

[0013] Another problem related to misalignment due to accumulated errors during manufacturing is that, especially when ultrasonic welding is used to form a transverse seal, the ink used to mark the package is degraded by the ultrasonic welding equipment and may separate from the package to form flakes

These ink flakes cause a number of problems including accumulating on the jaws of sealing equipment, releasing from the pouch when the pouch is dispensed at the point of use to at least visibly contaminate the product in which the pouch is placed, and otherwise contaminating the equipment. or product or both equipment and product issues

For example, to date, the industry has simply accepted these problems, perhaps due to the need to manufacture these bags at very high speeds to keep costs low, although these problems have occasionally resulted in unusable bags of products that need to be scrapped, salvaged Storage, immediate handling, etc., and the need to clean and seal machines due to ink buildup
