Description
CROSS REFERENCE TO RELATED APPLICATION
[0001] Not applicable
BACKGROUND OF INVENTION
[0002] This invention relates to closures for trash bags or other
bags which can be closed by puckering the open end of the bag. In
the past this procedure was completed by a variety of methods such
as the wraps, paper covered wires; pull strips (i.e. cinch sack)
and the like. U.S. Pat. Nos. 2,849,171; 3,412,296; 4,008,851 and
5,006,380 refer to these typical procedures. These arrangements are
lacking in efficiency and function. The tie wraps are often lost,
misplaced or break, the cinch does not totally seal the bag against
spillage or odor.
BRIEF SUMMARY OF INVENTION
[0003] This invention concerns the method and means for using
adhesion strips, which are typically permanently affixed near the
edge of an opening in a bag, to seal a bag after filling. Strips
located near the edge of a bag are uncovered upon completion of
fill and the bag is then squeezed together at the strip locations.
The bag is now sealed against spillage and odor. In other
embodiments more than the traditional one side of the bag is left
open during manufacture. This invention also enables the creation
of a bag from a flat sheet to be formed into a bag. This invention
further enables closure of a bag by mean other than adhesion
strips. Bag as described in this invention is intended to mean a
flexible container which is intended to enclosed desired
object(s).

DESCRIPTION OF PREFERRED EMBODIMENT
[0010] FIG. 1 is a depiction of a bag (1) with inner (5) and outer
(4) walls, incorporating the inventive aspect of a seal strip (6).
The strip is affixed to the inner wall (5) near the top (2) of a
bag (1). The bag (1) can be of any size and material as desired for
a particular application. The seal strip is typically a thin strip
with adhesive properties selected as appropriate for the material
of the bag to be sealed. The particular application will also
determine the mechanism for affixing the seal strip (6) to the
inner wall of the bag. The seal strip (6) will typically be affixed
using a compatible adhesive, but other means may also be used as
appropriate.
[0011] To provide a means for tightly sealing the bags (1), the
seal strip (6) is configured continuously around the inner wall (5)
parallel to the opening to be sealed. The dimensions of the seal
strip and the strength of its adhesive properties will be selected
to be compatible with the characteristics (size, use, wall
thickness, etc.) of the bag. The seal strip can be applied
permanently as part of manufacturing the bag or separate and
applied later. Typically, the bag will have one opening with one
seal strip in close proximity to the opening. If warranted by a
particular application multiple seal strips can be installed in
parallel to any openings to ensure seal integrity.
[0012] FIG. 2 a sectional view depicting the seal strip (6)
attached the inner wall (5) of a bag (1) with the seal strip
removable cover (3) on the seal strip (6). The removable cover (3)
remains in place until after the bag (1) is filled. The removable
cover (3) protects the seal strip from inadvertent sealing.
[0013] FIG. 3 depicts the bag (1) with the removable cover (3)
partially peeled away from the seal strip (6) exposing the adhesive
properties of the seal strip. The removable cover (3) is typically
a thin smooth strip appropriately sized to be compatible with the
seal strip. The material of the removable cover (3) is chosen to be
compatible with the seal strip (6) such that it will adhere to the
seal strip to isolate it from contact with other surfaces, but is
easily removed with minimal hand force.
[0014] FIG. 4 depicts the bag (1) sealed after being filled. The
bag (1) is squeezed or puckered at the location of the seal strip
(7) after the removable cover (3) is removed exposing the entire
seal strip (6) as depicted in FIG. 3.
[0015] FIG. 5 depicts a bag with the two open sides opposite each
other. This invention could be applied to any number of open sides
including a completely unformed bag consisting of a flat sheet with
seal strips affixed close to all outer edges as depicted in FIG. 6.
FIG. 6 depicts a circle shape to be formed into a bag, but this
invention could be used with any shape. Any portion of bag may be
preformed as desired.
[0016] This invention can be used for bags of any size or shape
warranted for a particular application including configuration not
typically thought as bags. For example, this invention could be
used with wrapping paper for gifts.
[0017] In another embodiment of this invention, the seal strips are
use to fabricate a double wall bag by placing one bag inside the
other with seal strips located as warranted to secure the inner and
outer bags together. This double wall could also be limited to a
particular area of bag such as the portion which will be the bottom
of the bag when it is full. In addition, more than 2 walls can be
constructed by this invention if additional leak protection is
desired.
[0018] The description above and accompanying figures are presented
as examples of the present invention. The scope of the present
invention is not limited by the exemplary embodiments. Other
applications and variations of the present invention are possible
to meet a particular application. For example, the seal strip can
be separate from the bag with removable covers on opposite sides
for removal and affixation to any formed or unformed bag as
desired. After forming a bag any unused portions can be cut
off.
