Vacuum-packing diaper at millibars of pressure

Abstract

A method of packaging a diaper includes: disposing the folded diaper within a flexible substantially air impermeable encasement; creating a vacuum state within an interior space defined by the encasement; and sealing the encasement such that the interior space of the substantially air impermeable encasement is completely sealed, and such that the compressible absorbent diaper is completely enclosed within the sealed interior space. Vacuum-packing of the diaper is done at millibars of pressure.

AI Technical Summary

Benefits of technology

[0010] It has been recognized that it would be advantageous to develop a packaged diaper that requires a relatively small amount of storage space. In addition, it has been recognized that it would be advantageous to develop a diaper and related accessory kit that consumes a relatively small amount of space while providing substantially all of the materials necessary to change an individual's diaper. It has also been recognized that it would be advantageous to develop an infant care kit that consumes a relatively small amount of space while providing substantially all of the materials necessary to feed the infant and change the infant's diaper.

[0011] The invention provides a packaged diaper, including a diaper, having a first, nominal size, and a second, reduced size, the reduced size of the diaper being convenient for carriage and storage of the diaper. An encasement can also be provided, in which the diaper can be disposed in the second, reduced size. The encasement can confine the diaper so that the diaper is retained in its reduced size by the encasement and so that the diaper is returned to its nominal size upon opening of the encasement.

Problems solved by technology

Individuals incapable of controlling the release of bodily waste in a manner sufficiently reliable to enable the use of restroom facilities, and those caring for such individuals, typically need to carry extra disposable diapers and changing accessories.

This is typically because it is difficult to predict when a diaper worn by an individual may need to be changed.

Storage and carriage of clean diapers is often inconvenient.

For instance, disposable diapers are generally rather bulky items not given to easy storage or carriage in a purse, pocket, or otherwise about the person.

In addition, the problem can be acerbated in that diapers can be subject to expansion from the typically somewhat compressed state in which they are normally provided to consumers, especially in circumstances where the diapers are subject to contact with other items within a storage bag.

However, after being removed from their original packaging, bi-fold diapers often unfold or otherwise expand to consume an even larger storage space.

Thus, disposable diapers can become more bulky and difficult to carry than when in their nominal, packaged condition.

In addition, it is often the case that it is not sufficient to simply change a soiled diaper and replace it with a clean diaper.

While a conventional diaper bag provides a dedicated container in which diapers and diaper accessories can be stored and carried, the requirement of carriage of a diaper bag often adds to the difficulty of a caretaker's responsibility.

While conventional clean diapers and diaper changing accessories can be stored and carried in other carrying containers such as purses, backpacks, briefcases, etc., the bulky nature of conventional disposable diapers results in the diapers occupying a relatively large space within the carrying container.

In addition, diaper changing accessories such as moist wipes, ointment, powder, etc., add to the space consumed by conventional clean diapers and can be difficult to locate among other items stored in the backpack, purse, case, or the like.

Where the diapers being carried by the caretaker are for bottle feeding infants, the problems discussed above are further exacerbated by the need to carry materials for feeding the baby.
