Storage systems for milk bags

Embodiments of the present invention are directed to storage systems for milk bags. A storage system for milk bags receives milk bags and management of the stored milk bags. The milk bags are stored in compartments for easy storage and retrieval.

FIELD OF THE INVENTION

The present invention is related to the field of storage systems. More specifically, the present invention relates to storage systems for milk bags.

BACKGROUND OF THE INVENTION

Breast milk can be frozen up to many months before it is used. Breast milk can be stored in milk bags.FIG. 1illustrates an exemplary milk bag100. A milk bag100is similar to a Ziploc® bag, in which it has a fastener105to close the milk bag100and to separate a tag110from the storage or bag area115. Milk is contained in the storage area115. Typically, the tag110allows for information to be written onto, such as name, date and amount of milk is in the milk bag.

InFIG. 1, the milk bag100has dimensions A and B as shown. Typically, the width of the milk bag100at the bottom is bigger than the width of the milk bag100at the top, so that the milk bag100can be positioned vertically in the freezer. One problem with positioning the milk bag100vertically is that it takes up too much room in the freezer or has a tendency to fall over. As such, to save space in the freezer, the milk bag100can be positioned horizontally. By positioning the milk bag100horizontally, the milk bag100can therefore be stacked on top of and/or below other milk bags. However, a problem with stacked milk bags is that they can become “stuck” because of frost. Another problem with stacked milk bags is that the top milk bag may slide off a bottom one; the frozen milk bag would have a deformed or awkward shape because of the way the milk bag slid off and landed prior to it being frozen. In addition, a frozen milk bag can have a shape that is off because of grates or other objects in the freezer. As parents, guardians, and caregivers know, frozen milk bags must be handled with care because the edges are delicate and can rupture if not handled with care; when defrosting the milk, the milk will become wasted as it will drip out of the punctured bag. Another problem with stacked milk bags is that it is difficult to retrieve a milk bag with the earliest date since it would be at a bottom of the stack and/or towards the back of the freezer. The desire is to use old milk first to avoid wasting such precious food since it has a suggested expiratory lifetime.

The present invention addresses these limitations in the prior art.

DETAILED DESCRIPTION OF THE INVENTION

In the following description, numerous details are set forth for purposes of explanation. However, one of ordinary skill in the art will realize that the invention can be practiced without the use of these specific details. Thus, the present invention is not intended to be limited to the embodiments shown but is to be accorded the widest scope consistent with the principles and features described herein.

Embodiments of the present invention are directed to storage systems for milk bags. A storage system for milk bags receives milk bags and management of the stored milk bags. The milk bags are stored in compartments for easy storage and retrieval.

It should be understood that although milk and milk bags are described with respect to the storage systems of the present invention, other liquids and other types of bags are contemplated and can be used with the storage systems.

Although different storage systems will now be described, all storage systems can include material to prevent or minimize freezer burn.

Fixed Housing with Fixed Compartments

FIG. 2illustrates an exemplary storage system200in accordance with the present invention. The storage system200typically fits within a freezer and includes a housing205having fixed compartments or units or slots, which are divided using shelves210. Each compartment is sized and configured to receive a milk bag, such as the milk bag100illustrated inFIG. 1. The height of each compartment is fixed, although in some embodiments the shelves210are removable along tracks disposed on inner surfaces of the housing205. In such an embodiment, the spacing of a compartment can be, for example, doubled by removing a shelf210or tripled by removing two shelves210. Thus, the height of a compartment is incremented by a fixed factor. Without removing the shelves210, the storage system200allows storage of x milk bags, with x being the number of compartments in the storage system200.

When in use, milk bags are positioned horizontally within the compartments with the tags of the milk bags hanging out of the compartments so that information about the milk can be easily read. In some embodiments, additional information can be written on and erased from front sides or surfaces of the shelves210.

In some embodiments, removable markers215can be used to indicate freshness of milk and other characteristics, such as if the mother drank coffee/tee/caffeinated drink, or if the mother ate some food that may have caused her to have heartburn, etc. The removable markers215typically clip with portions of the storage system200, such as a shelf210or the housing205. The removable markers215can vary in shape and color. For example, a mug-shaped marker can indicate that the mother drank a caffeinated drink prior to expressing milk. For another example, a blue-colored marker can indicate that the milk was expressed for ½ hour before being frozen. Other colors and shapes are contemplated.

In some embodiments, interior surfaces of the storage system100can include material to minimize or prevent freezer burn. For example, the material can be silicone or the like.

Fixed Housing with a Molding Mechanism

FIG. 3illustrates another exemplary storage system300in accordance with the present invention. The storage system300is similarly configured to the storage system200except that each compartment includes molding mechanism320configured to mold the shape of a milk bag as the milk therein freezes. For example, each inner side of a compartment is concave such that the compartment has an oblong receptacle for receiving a milk bag. A frozen milk bag can be retrieved from the receptacle and placed in a mug, for example, to defrost.

Fixed Housing with Flexible Compartments

The amount of milk stored in a milk bag typically varies each time. There are times when not much milk is stored in a milk bag, while there are other times when more milk is stored in a milk bag. Compartments with fixed sizes do not allow additional milk bags to be stored therein and/or do not accommodate milk bags containing more milk.FIG. 4Aillustrates another exemplary storage system400in accordance with the present invention. As further explained below, the storage system400advantageously allows more or less milk bags to be stored and allows milk bags with any amount of milk to be stored.

The storage system400typically fits within a freezer and includes a housing405and removable shelves410. The storage system400does not have fixed compartments. Instead, a frozen milk bag defines the size of its respective compartment. In some embodiments, interior walls of the housing405and/or at least a portion of the perimeter of each shelf410include silicone or high friction material to engage the shelf410with the interior walls of the housing405, as illustrated inFIG. 4B. Silicone can also help prevent or minimize freezer burn.

When in use, milk bags are positioned horizontally with a shelf410separating two consecutive milk bags. Put differently, a milk bag is placed horizontally in the housing405, a shelf410is placed on top of it to thereby separate the milk bag from another, creating its own uniquely-sized compartment. As the milk freezes, the milk bag expands, pushing the shelf410upwards at a minimum distance, without wasting space in the housing405for other milk bags to be stored.

In some embodiments, a shelf410is weighted so that milk in a milk bag can be leveled within the milk bag. In some embodiments, a top portion410aof the shelf410is flat and rigid to provide a level platform for the next milk bag to be placed on top of. In some embodiments, a bottom portion410bof the shelf410is slanted or angled such that thickness of the shelf410at one end is not the same as the thickness of the shelf410at the other end to compensate for the uneven expansion of the milk. In some embodiments, the bottom portion410bof the shelf410is flexible to compensate for the expansion of bag having any amount of milk to thereby provide the level platform for the next milk bag. For example, the bottom portion of the shelf includes beads or the like, such as gel or liquid, therein. The beads can be made of Styrofoam®.

In some embodiments, a shelf410is not weighted. Rather, a top weight is used to level the milk bag. In other words, in use, a first milk bag is placed horizontally in the housing405. Then, a first shelf410is placed on top of the milk bag. Then, the top weight is placed on top of the first shelf410. When putting another milk bag in the housing, the top weight is first removed before the another milk bag is placed on top of the first shelf410. A second shelf410is placed on top of the another milk bag with the top weight placed on top of the second shelf410. The top weight is able to be slightly smaller than the width and/or the length of the shelf410, such that the top weight is able to make the milk bag level and even. In some embodiments, the top weight is similarly sized and shaped as a shelf410.

FIG. 4Cillustrates a front view of the storage system400when in use. As illustrated inFIG. 4C, milk bags in the housing405are separated by shelves410. The tags of the milk bags hang out of the housing305so that information about the milk can be easily read.

In some embodiments, markers similarly configured as the markers215can be used with the storage system400. In some embodiments, front surfaces of the shelves410are configured to be marked with information, such as with a dry erase pen.

Unused shelves410can be stored separately or coupled to the housing405. For example, a side of the housing405includes a protrusion, and each shelf410includes a hole configured to receive the protrusion. For another example, a side of the housing405includes clips to clip the shelves410to. Other mechanisms for coupling the shelves410to the housing405are contemplated.

Collapsible Housing

FIG. 5illustrates yet another exemplary storage system500in accordance with the present invention. The storage system500includes a collapsible housing505and removable shelves (not illustrated). The storage system500is similarly configured as the storage system400; for example, the shelves can be similarly configured as the shelves410. However, the collapsible housing505advantageously accommodates any freezer size (e.g., height of freezer) because of its accordion like structure.

Framed Housing

FIG. 6illustrates yet another exemplary storage system600in accordance with the present invention. The storage system600includes a framed housing605. The framed housing605includes a first end and second end, and planar dividers610aand angular dividers610bthat form fixed slots with openings at both ends of the storage system600(e.g., tag end). The planar dividers610aand angular dividers610bform triangular-shaped compartments.

Milk bags are inserted from both ends, with the top of the milk bag inserted in the housing605first. In some embodiments, there are tooth-like features615that protrude from each shelf to “hold back” a milk bag so that it doesn't slide out. In some embodiments, each tooth-like feature615extends from an end of an angular divider610btowards a planar divider610a.

In some embodiments, the tooth-like features615are configured to be marked with information. In some embodiments, markers similarly configured as the markers215can be used with the storage system600.

FIG. 7illustrates yet another exemplary storage system700in accordance with the present invention. The storage system700typically fits within a freezer and includes a rolodex-like housing705with having fixed compartments or units or slots, which are divided using shelves710. Each compartment is wedge-shaped and is sized and configured to receive a milk bag, such as the milk bag100.

In some embodiments, each compartment includes a molding mechanism, such as the molding mechanism230, to mold the shape of a milk bag as the milk therein freezes.

In some embodiments, the storage system700is able to be configured in a closed position, in a fully opened position, and a semi opened position which is any position the closed configuration and the fully opened configuration. When the storage system700is in the fully opened configuration, all the compartments open up like a fan.

In a fully opened configuration, the storage system700has a height X and a diameter Y. If the height of a freezer is smaller than X or if the depth of the freezer is smaller than Y, then the storage system700need not be in the fully opened configuration for the storage system700to be used. Instead, the storage system700is opened to a configuration permitted by the dimensions of the freezer.

As the storage system700opens, a compartment opens up to receive a milk bag. Typically, each shelf is substantially planar and rigid. Each shelf can include a tab for easily opening up to a respective compartment. In some embodiments, the tab is coupled to the front of the shelf.

Bare Housing

FIG. 10illustrates yet another exemplary storage system1000in accordance with the present invention. The storage system1000typically fits within a freezer and includes a bare housing1005with no shelves. Instead, the storage system1000includes removable compartments1010. Each compartment1010is sized and configured to be received by the housing1010. Each compartment1010is also sized and configured to receive a milk bag. In some embodiments, the housing1010is collapsible.

When storing a milk bag, the milk bag is inserted into a compartment1010. Typically, the tag of the milk bag hangs out. When milk is desired, an entire compartment1015can be removed from the storage system1000. The milk bag need not to be removed from the compartment1010since the compartment1010can advantageously be used as a container to defrost the milk bag in. Alternatively, a frozen milk bag can be removed from the compartment1010while the compartment1010is left in the storage system1000.

The storage systems discussed in relation toFIGS. 2-7and10allow a frozen milk bag to be stored in an organized manner for, among other things, easy retrieval. Furthermore, since the milk bags are organized within the storage system, donating frozen milk via shipment becomes more convenient since the entire storage system can be shipped. In some embodiments, the storage system includes a handle for transportation. In some embodiments, the storage system is made from durable, yet light weight material. In some embodiments, the storage system is made of silicone or other material to prevent milk from over-freezing and/or to equalize temperature within the storage system.

Using a Storage System

FIG. 8illustrates an exemplary method800of using one of the storage systems400,500in accordance with the present invention. The method800begins at a step805, where the storage system, particularly its housing, receives a bag such as a milk bag. The milk bag contains a liquid, such as milk. The milk bag is placed horizontally within the housing of the storage system. If this milk bag is the first milk bag to be stored in the storage system, then it is placed on an inner surface of the housing at the bottom of the housing. If this is milk bag not the first milk bag in the storage system, then it is placed on a shelf. If a separate weight is used, the separate weight is removed prior to the placement of the milk bag in the storage system. After the milk bag is placed within the storage system, either as the first milk bag or a subsequent milk bag in the storage system, at a step810, a shelf is placed on top of the horizontally placed milk bag. The shelf typically has a rigid planar top surface for level placement of a subsequent milk bag and an angled bottom surface to compensate for the uneven expansion of milk within the milk bag. In some embodiment, the shelf is weighted for leveling the milk in the milk bag. In some embodiments, the shelf is not weight. In some embodiments, the separate weight is placed on top of the shelf to thereby level the milk in the milk bag. At a step815, as the milk bag expands, the shelf rises or is otherwise pushed upwards until the milk in the milk bag freezes. Adjustable compartments for the milk bags are created by using shelves that move upwards within the storage system as milk in the milk bags freezes. A compartment of a storage bag is advantageously sized specifically for the storage bag. After the step815, the method800ends.

The method800can be repeated for each milk bag to be stored until there no longer is sufficient space for the storage of an additional milk bag.

Thawing Container

FIG. 9illustrates an exemplary thawing container900in accordance with the present invention. The thawing container900is configured to receive a frozen milk bag for defrosting. In some embodiments, the thawing container900includes an indicator for indicating how long the milk has been thawing, how much longer the milk needs to thaw, or both.

Water can be added in the thawing container900to speed up the thawing. In some embodiments, the thawing container900also includes an electronic warmer configured to speed up the thawing process.

In some embodiments, the thawing container900fits within a storage system housing, such as the housing1005.

One of ordinary skill in the art will realize other uses and advantages also exist. While the invention has been described with reference to numerous specific details, one of ordinary skill in the art will recognize that the invention can be embodied in other specific forms without departing from the spirit of the invention. Thus, one of ordinary skill in the art will understand that the invention is not to be limited by the foregoing illustrative details, but rather is to be defined by the appended claims.
