Description
This invention relates to a device for holding a bag upright with
its upper end opened to permit easy placement of articles into the
bag.
In the field of preserving and canning of foods, and particularly
the home preserving of foods, convenient containers are necessary
to hold the foods after they have been prepared. Thin-walled
plastic bags are commonly used by home canners for this purpose.
They are inexpensive, not subject to breakage, provide a good means
for sealing the food therein and are disposable after use. With all
these advantages, however, such thin-walled plastic bags are
somewhat difficult to use because they are very flexible and are
not so easily positioned to allow the user to place prepared food
into the bag.
Numerous devices have been proposed for aiding the filling of bags.
One, as shown in Smith U.S. Pat. No. 56,819, takes the form of a
hoop supported by a stand or the like. A bag is secured to the hoop
by inserting it from below through the loop and then turning the
open end over the upper edge of the hoop. After this has been done,
a funnel-like member is disposed with its lowermost end projecting
inside the open-topped bag while its sloping outer surface wedges
the bag between the funnel and the hoop. However, the bag, being
supported entirely by the hoop, can stretch or slide out of the bag
holder as it is filled.
In another bag-holding apparatus, as shown in U.S. Pat. No.
2,688,429, a funnel member is provided which has a lower portion
shaped so that it can be inserted into the interior of a bag placed
in a receptacle. The area between the lower portion of the funnel
and the receptacle comprises a slot for holding the bag. The bag
can slip out of the slot, however, and may bulge non-uniformly as
it is filled.
It is a primary object of this invention to provide a holder for a
thin-walled bag, such as a freezer bag, in an open position to
permit foods and the like to be placed therein without causing the
bag to slip free, bulge, or stretch as it is filled.
To accomplish these and other objectives, a two-part interfitting
bag holder has been developed. A bag support member, open at its
top and bottom, has an annular upper lip or rim around which a
skirt on a second, funnel-like, member fits. The bag is positioned
in the bag support member with its open end folded outwardly and
downwardly over the upper rim of the latter. The funnel-like member
fits on the bag support member and provides unobstructed movement
of the food into the bag. The funnel-like member has a bearing
surface for resting on the upper surface of the upper rim, and it
presses the bag down on the latter rim. The skirt clamps the bag
around the rim, and it also has an angled lower edge for catching
the bag so that it does not slide out from between the skirt and
rim.
The above and other objects, features, and advantages of this
invention will become more clear from the following detailed
description of a preferred embodiment thereof as shown in the
drawings, wherein:
FIG. 1 is an exploded perspective view, partially in section,
showing the two parts of the bag holder, with a bag placed in the
bag support member, and
FIG. 2 is a vertical section showing the two bag holder parts in
their interfitted relation and clamping a bag in position for
filling.
The bag support member designated generally at 10 is generally
tubular in shape, and is open at each end for bag insertion and
filling, as will be discussed. The tubular body has a circular or
cylindrical upper end or rim 14. Below the rim it flares outwardly
at a rounded shoulder 12 of larger diameter than the rim 14.
A second part of the bag holder comprises a funnel-like member 18
which fits around the upper rim 14 of bag support 10. Interiorly,
member 18 includes a frusto-conical funnel surface 20 for directing
articles through the open top part of the thin-walled flexible bag
such as the freezer bag shown at 16. The funnel-shaped member also
includes a downwardly facing flat annular bearing surface 22 shaped
to rest upon the flat annular top surface 24 of upper rim 14.
Surface 22 of the funnel member 18 intersects inside funnel surface
20 at the neck thereof, and at this plane (see FIG. 2) the inside
diameter of funnel surface 20 is no larger than, and preferably is
less than, the inside diameter of upper rim 14.
Extending downwardly from funnel surface 20 and below bearing
surface 22 thereof, is a rim-encircling skirt or flange 26. This
has an acutely angled edge 28 at its lowermost end. Skirt 26 and
the angled edge 28, as will be described, cooperate with rim 14 and
shoulder 12 respectively in holding the freezer bag in its open
position.
Both the bag support member 10 and funnel member 18 are
conveniently made of metal or preferably of plastic, e.g.
polypropylene or polyethylene, or impact polystyrene.
In use, a freezer bag 16 is inserted into bag support member 10
through the open lower end 29 thereof, and the top part of the bag
extends upwardly through the opening defined within upper rim 14.
The top part of freezer bag 16 extends above and out of the bag
support member a sufficient distance so that the open end of the
bag can be folded outwardly and downwardly around the upper rim
14.
In FIG. 2, the funnel member 18 is shown interfitted with the bag
support member 10 to hold the bag 16 in place for filling. In this
position the thin-walled bag 16 is held so that food or other
articles poured into funnel member 18 will be directed into it.
Surface 22 provides a bearing surface for member 18 and rests upon
the bag where it is folded over top surface 24.
The downwardly extending funnel skirt 26 has an inner diameter
slightly larger than the outer diameter of the upper rim 14 so as
to provide room for the downwardly folded portion of the bag 16
which is clamped between skirt 26 and rim 14. The spacing between
skirt 26 and rim 14 should be sufficient to accommodate the
thickness of bag 16 yet tight enough to provide a gripping action
to secure the bag in open position and prevent it from slipping
while being filled.
The angled tip or edge 28 at the lowermost end of skirt 26 is
shaped to fit against the surface of shoulder 12, and when the
funnel 18 is seated on member 10, edge 28 catches onto and thereby
helps hold the downturned edge of the bag 16.
As shown in FIG. 2, funnel surface leads inwardly of the inner edge
of the annular top surface 24 of rim 14. Articles will slide down
the frusto-conical shaped surface 20 past surface 24 and then will
fall directly into bag 16. There are no edges or obstructions
projecting inwardly into the funnel opening and no food can
accumulate on the top of member 10.
As the bag 16 is filled, it will expand outwardly until it rests
against and is confined by the inside of bag support member 10.
Furthermore, assuming that the bag 16 is positioned inside bag
support member 10 with its bottom resting on support surface 30,
the bag 16, as it is filled, will be supported by surface 30 rather
than hanging from upper rim 14, as in some prior art bag holders.
Since it is confined laterally, and does not hang free, bag 16 will
not be stretched and will fill uniformly.
Once the bag has been filled, the funnel-like member 18 is removed
from the position shown in FIG. 2 so that the open end of the bag
may be closed by tying a knot in the bag or securing it with a
suitable tying material. Once the bag 16 has been sealed, the bag
support member 10 is lifted off, thereby permitting the filled bag
16 to pass through the open bottom of the bag support member 10,
ready for subsequent storage, freezing, etc.
While the foregoing description has been made with particular
emphasis upon a preferred embodiment of this invention, it will be
clear to those skilled in the art that modifications in form may be
made without departing from the spirit and scope of this invention,
as defined in the following claims.
