Description
PRIORITY CLAIM
[0001] This invention claims priority from provisional application
No. 60/347,274, filed Jan. 9, 2002.
FIELD OF INVENTION
[0002] This invention relates to storage containers, particularly
including containers for storing fresh herbs and certain
vegetables.
BACKGROUND OF INVENTION
[0003] Many people cook with fresh herbs, and recipes often call
for fresh herbs as ingredients. Many fresh herbs are very expensive
and are often purchased in a pre-packed quantity. The pre-packed
quantity of herbs is usually more than is needed in a recipe,
leaving leftover herbs that require storage.
[0004] Typically, fresh herbs are stored in the plastic bag or thin
plastic container that they are purchased in. This is problematic
because the leaves often sit in pools of water or condensation,
causing them to decompose and rendering them unfit for consumption.
The thin poly-bags are also not air-tight, exposing the herbs to
ethylene gas from other fruits and vegetables. As with
condensation, ethylene gas causes the herbs to age and decompose at
a faster rate.
[0005] There is nothing on the market that is capable of keeping
all types of fresh herbs fresh for extended periods by protecting
them from condensation, air, ethylene gas, and other harmful
refrigerator odors. The few devices presently used have many
shortcomings. For example, there is an item called the "parsley
bag" that is a double-walled cotton cloth bag designed to store
parsley and other herbs. The bag is moistened with water, the herbs
are placed inside, and the bag is closed with a drawstring. This
bag does not protect the herbs from refrigerator odors or from
harmful gases. The bag is also crushable, so that if it is not
given adequate space in the refrigerator, the herbs inside will be
damaged or rot quickly due to lack of air space.
[0006] Accordingly, there is a need for a product that can hold
herbs upright, keeping the leaves away from water, while sealing
out refrigerator odors and gases that accelerate the aging of the
herbs. Preferably, such a device should be convenient to store in
the refrigerator or on a countertop, and able to store multiple
types of herbs and certain vegetables at the same time.
DESCRIPTION OF ILLUSTRATIONS
[0007] FIG. 1 is a perspective view of a preferred container in
accordance with the present invention; and
[0008] FIG. 2 is a perspective view of a preferred container having
an internal herb separator in accordance with the present
invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0009] The present invention is a container for storing fresh herbs
and certain vegetables to retain freshness for extended periods.
Though it is sometimes referred to as an herb keeper because it is
best suited for storing herbs, it is also capable of storing
certain vegetables and other perishables, particularly including
leafy vegetables. Within this specification, herbs and other leafy
vegetables capable of storage in the container are generally
referred to as produce. Likewise, most herbs and leafy vegetables
will have a section that is generally "leafy" and a section that is
essentially a "stem." The stem is defined as the portion of the
herb or leafy vegetable that was attached to the stalk, while the
leafy portion extends away from the stem.
[0010] With reference to FIG. 1, the container 10 consists of three
main parts: a cap 40, center tube 20 and base cup 30. Preferably,
the center tube 20 and base cup 30 are made of clear acrylic and
the cap is made of a thermoplastic elastomer (TPE). Any of the
components may alternatively be formed of other materials, although
it is preferable to form them from clear materials so that the
types of herbs that are stored remain visible.
[0011] The base cup 30 is a relatively shallow, substantially
cylindrical cup having a flat, circular base 32 and generally
vertical walls. The walls may also be inclined somewhat, so that
they extend radially outwardly as they extend away from the base.
The base cup includes a marking 50 on the outside to indicate the
level of water that should be added to the base cup 30 to keep the
stored herbs fresh. The base cup 30 holds the herbs upright, with
the lower section of the herb stems 62 submerged in the water and
the herb leaves 61 out of the water, as with a vase of cut
flowers.
[0012] The center tube 20 threads onto the base cup 30, although it
may alternatively be friction, snap, or otherwise joined to the
base cup 30. The center tube 20 is therefore removably attached to
the base cup to make it easier to add or remove herbs. The center
tube 20 holds the herb leaves or branches upright to allow adequate
air circulation and to keep them out of water. Preferably, the
axial length of the center tube is greater than its diameter to
produce a generally elongated shape that will hold herbs
upright.
[0013] While the preferred embodiment includes a two-piece center
tube and base cup arrangement, the invention may also be produced
by constructing these components as a single integrated unit. One
of the advantages of the two-piece construction is that by adding
the herbs and water to the base unit before attaching the center
tube, it helps to ensure that the water level remains low, below
the leafy portion of the herbs.
[0014] The removable cap 40 is frictionally attached to the center
tube 20. The relatively snug fit between the cap 40 and the center
tube 20 produces a substantially airtight seal. Consequently, the
herbs are protected from refrigerator odors and damaging ethylene
gas produced by many fruits and vegetables. The cap 40 can be
opened to insert or remove herbs.
[0015] Although the cap 40 is preferably friction-fitted to the
center tube 20, it can alternatively be removably attached via
mated threads between the cap 40 and the center tube 20, a snap-fit
(e.g., annular, mating ridges), or any other means that will retain
the cap 40 and substantially seal the container.
[0016] Preferably, the container 10 is made from clear materials so
that the herbs that are stored inside are visible and readily
identifiable. Other materials may also be used, however, such as
glass, ceramic, stainless steel, or polyethylene.
[0017] As illustrated in FIG. 2, the container 10 optionally
includes an internal divider insert 70 to separate herbs or bunches
of herbs and further assist in keeping them upright. The insert 70
comprises two vertical wall sections 72, 74, each of which bisects
the base cup vertically. The wall sections 72, 74 are also
orthogonal to one another, thereby dividing the base cup into four
quadrants. The divider insert 70 preferably is formed from the same
material as the center tube 20 and is about the same height as the
base cup 30. Preferably, the insert is removable, although it may
be permanently affixed or integrally molded with the base cup 30 or
center tube 20.
[0018] In alternate forms, the divider insert may extend a much
shorter distance, or may take the form of bars extending radially
across the center tube 20, so long as the insert is capable of
keeping the stored herbs separated. Likewise, the internal insert
may either stop short of the bottom of the base cup 30 or include
openings in the portion of the insert that is at the bottom of the
base cup so that water in the base cup 30 will be shared across the
separate sections. The insert allows the container to be divided
into any number of internal sections.
[0019] In yet another embodiment, the container includes a
plurality of spikes extending upward from the base cup toward or
into the center tube. The spikes provide support for the herbs to
keep them generally upright during storage.
[0020] In another alternative embodiment, the container is
expandable in height. The height adjustment is preferably
accomplished via an overlapping sliding friction fit between the
base cup 30 and the center tube 20. By sliding the center tube 20
up or down with respect to the base cup 30, the container becomes
taller or shorter.
[0021] The herb keeper of the present invention keeps herbs fresher
longer than existing devices, and is capable of holding multiple
types of herbs at the same time. It can easily be used in the
refrigerator or on a countertop. The preferred size and shape will
fit in typical refrigerator doors. Though it is best suited for
herbs, it is also ideal for storing certain vegetables such as
spinach and asparagus.
[0022] The air-tight seal keeps delicate herbs away from ethylene
gas released by fruits and vegetables that are typically stored in
a refrigerator. When constructed from the preferred clear acrylic
material, it allows the contents to be identified without opening
the container.
[0023] While the preferred embodiment of the invention has been
illustrated and described, as noted above, many changes can be made
without departing from the spirit and scope of the invention.
Accordingly, the scope of the invention is not limited by the
disclosure of the preferred embodiment.
