Storage bag for breast pump

Abstract

The disclosure regards a storage bag for breast milk or other liquids or materials. The storage bag includes first and second closures, wherein a first line of perforations is U-shaped and extends through the first closure, thereby allowing an output of a breast pump or other device to be inserted through the area where material defined by the first line of perforations is removed. The first closure can further be used to engage the output of the breast pump or other device. A second closure is formed further within the storage bag and defines a storage volume. A second line of perforations is provided above the second closure. After the storage volume is filled, the second closure can be closed and the material above the second line of perforations can be removed.

What is claimed is: 
     
         1 . A storage bag including:
 a wall structure defining a storage volume, a closed bottom and an open top;   a first closure closing the open top;   a second closure at a position in the wall structure between the first closure and the closed bottom, wherein the storage volume is formed between the second closure and the closed bottom;   a first line of weakness having a U-shape and extending from the open top and passing through the first closure; and   a second line of weakness extending across the wall structure between the first closure and the second closure.   
     
     
         2 . The storage bag of  claim 1  wherein the first closure is adhesive and the second closure is a zipper. 
     
     
         3 . The storage bag of  claim 2  wherein the first line of weakness has a U-shape with ends that terminate at the open top, and which defines an area which includes a portion of the first closure. 
     
     
         4 . The storage bag of  claim 3  wherein tearing along the first line of weakness removes a portion of the first closure. 
     
     
         5 . The storage bag of  claim 4  wherein tearing along the first line of weakness and removing the area defined by the first line of weakness creates a port for receiving material for the storage volume. 
     
     
         6 . The storage bag of  claim 5  wherein the second line of weakness has an upwardly arcing shape. 
     
     
         7 . The storage bag of  claim 6  wherein a labeling area is provided on the wall structure between the second zipper and the second line of weakness. 
     
     
         8 . The storage bag of  claim 7  wherein the zipper includes a first zipper profile with a first interlocking element and a second interlocking element and a second zipper profile with a third interlocking element and a fourth interlocking element, wherein the first interlocking element engages the third interlocking element and the second interlocking element engages the fourth interlocking element. 
     
     
         9 . The storage bag of  claim 8  wherein the adhesive is a surface treatment. 
     
     
         10 . The storage bag of  claim 9  wherein the wall structure comprises polymeric material. 
     
     
         11 . A breast milk storage bag including:
 a wall structure defining a breast milk storage volume, a closed bottom and an open top;   a first closure closing the open top;   a second closure at a position in the wall structure between the first closure and the closed bottom, wherein the breast milk storage volume is formed between the second closure and the closed bottom;   a first line of weakness having a U-shape and extending from the open top and passing through the first closure; and   a second line of weakness extending across the wall structure between the first closure and the second closure.   
     
     
         12 . The breast milk storage bag of  claim 11  wherein the first closure is adhesive and the second closure is a zipper. 
     
     
         13 . The breast milk storage bag of  claim 12  wherein the first line of weakness has a U-shape with ends that terminate at the open top, and which defines an area which includes a portion of the first closure. 
     
     
         14 . The breast milk storage bag of  claim 13  wherein tearing along the first line of weakness removes a portion of the first closure. 
     
     
         15 . The breast milk storage bag of  claim 14  wherein tearing along the first line of weakness and removing the area defined by the first line of weakness creates a port for receiving an output from a breast milk pump whereby breast milk is supplied to the storage volume. 
     
     
         16 . The breast milk storage bag of  claim 15  wherein the second line of weakness has an upwardly arcing shape thereby providing either a pour spout for the breast milk or pull tabs to insert the breast milk storage bag into a baby bottle after the second line of weakness has been torn. 
     
     
         17 . The breast milk storage bag of  claim 16  wherein a labeling area is provided on the wall structure between the second closure and the second line of weakness. 
     
     
         18 . The breast milk storage bag of  claim 17  wherein the zipper includes a first zipper profile with a first interlocking element and a second interlocking element and a second zipper profile with a third interlocking element and a fourth interlocking element, wherein the first interlocking element engages the third interlocking element and the second interlocking element engages the fourth interlocking element. 
     
     
         19 . The breast milk storage bag of  claim 18  wherein the adhesive is a surface treatment. 
     
     
         20 . The breast milk storage bag of  claim 19  wherein the wall structure comprises polymeric material.
