Abstract

The present invention relates to a method for producing a squeeze tube with maximal surface area labeling and a tube produced thereby.

First claim

What is claimed is:

1. A method for producing a squeeze tube with maximal surface area labeling comprising:
(a) pretreating a preformed tube with flame, plasma, or corona to obtain a dyne level of at least 38;
(b) adhering a label to the preformed tube with a solvent, emulsion, or hot-melt adhesive, wherein substantially all of a label surface is adhered to and covers the surface of the preformed tube as well as extending into and including at least a portion of a seal, with a peel strength adhesive value between the label and the preformed tube in the range of 800 to 2500 grams/inch at 12 inches/minute pull speed, and wherein the label is not a component of the preformed tube material; and
(c) sealing through one end of the preformed tube and label adhered to said preformed tube at the seal by heating only an internal surface of the tube before applying sealing pressure so that a squeeze tube is sealed, wherein the label encompasses at least a portion of the seal of the squeeze tube thereby producing a squeeze tube with maximal surface area labeling.

2. A squeeze tube produced by the method of claim 1 .

3. The method of claim 1 wherein the label covers the tube from near a proximal end to a distal end including within the seal.

4. The method of claim 1 , wherein the adhesive value between the label and the preformed tube in the range of 800 to 2500 grams/inch at 12 inches/minute pull speed provides for the label to withstand moisture resistance testing, oven temperature storage at 45 degrees Celsius, product resistance, water submersion, soapy water testing, eight weeks-long term storage at 45 degrees Celsius, and flexing for filled and unfilled tubes.

5. The method of claim 1 , wherein the label is coated with a solvent-based, water-based, or radiation-curable coating to provide abrasion resistance.

6. The method of claim 1 , wherein the label is individually cut and applied.

7. The method of claim 1 , wherein the label is carried on and applied from a web liner material.

8. A method for producing a squeeze tube with maximal surface area labeling comprising:
(a) adhering a label to a tube film with a solvent, emulsion, or hot-melt adhesive, wherein substantially all of a label surface is adhered to and covers the surface of the tube film, and wherein the label is not a component of the tube film material;
(b) subsequently generating a tube from the labeled tube film;
(c) sealing through one end of the tube and label adhered to said tube at the seal by heating only an internal surface of the tube before applying sealing pressure so that a squeeze tube is sealed, wherein the label encompasses at least a portion of the seal of the squeeze tube thereby producing a squeeze tube with maximal surface area labeling.

9. A squeeze tube produced by the method of claim 8 .

10. The method of claim 8 wherein the label covers the tube from near a proximal end to a distal end including within the seal.

11. The method of claim 8 , wherein the label is coated with a solvent-based, water-based, or radiation-curable coating to provide abrasion resistance.

12. The method of claim 8 , wherein the label is unsupported printed film subsequently laminated to the tube.
