Description
RELATED APPLICATION
[0001] This is the U.S. international phase application of
International Application PCT/CN2014/071535, with an international
filing date of Jan. 27, 2014. The present application claims the
benefit of the Chinese Patent Application CN201410033692.X filed
Jan. 24, 2014, which is incorporated herein by reference in its
entirely.
FIELD OF THE INVENTION
[0002] The invention relates to the technical field of foodstuff
packaging, in particular to a microwave oven steaming/cooking bag
for prepackaged foodstuff.
BACKGROUND OF THE INVENTION
[0003] The plastic zipper, owing to characteristics such as light
weight, good flexibility, low price and repeated use, is widely
applied to the packaging field. Though being small and
unspectacular, the zipper gains a rapid development in the
packaging industry. Currently speaking, the zipper with extensive
application in the market comprises two separate parts, namely a
male strip and a female groove; and the edge materials and the
structures of the male strip and the female groove are basically
the same. During heat sealing, the male strip and the female groove
are ironed and pressed onto the two sides of an opening of the bag,
so that excellent effects of opening and closing the bag
repeatedly, keeping the freshness and the safety of content in the
bag, and prolonging the shelf life of the content are achieved.
However, such common microwave oven steaming/cooking bag has the
following disadvantages: due to a fact that an exhaust hole is
opened after a bag is manufactured, the bag body is also holed and
the prepacked foodstuff is exposed to the outside easily; as a
result, the consumer feels troublesome in operation and the
foodstuff also cannot be preserved well.
OBJECT AND SUMMARY OF THE INVENTION
[0004] To overcome afore-mentioned disadvantages, the invention
provides a microwave oven steaming/cooking bag for prepackaged
foodstuff; a tear-off strip or a single-layer thin-film material is
arranged on the outer layer of the exhaust hole, so during the
material filling process, leakage of a material from the exhaust
hole is prevented.
[0005] Technical schemes of the invention are as follows: the first
technical scheme: a microwave oven streaming/cooking bag for
prepackaged foodstuff, wherein two rows of male strips and female
grooves meshed with each other are arranged at opposite positions
in a bag body; the male strips and the female grooves are connected
onto the bag body through two thin films respectively; at least one
exhaust hole is formed in the thin film either between the male
strips or between the female grooves or between one male strip and
one female groove at one side of the bag body; and a tear-off strip
is superposed on the bag body above the exhaust hole, so that the
internal exhaust hole can be exposed out after the tear-off strip
is torn open.
[0006] The open strength of a zipper above the exhaust hole is 80
N/50 mm, and the open strength of the zipper below the exhaust hole
is 30 N/50 mm. Through tearing open the tear-off strip, putting the
foodstuff into a microwave oven and starting the microwave oven,
and due to the action of hot gas pressure, the zipper an the lower
row is burst open by steam and the steam is exhausted from the
exhaust hole, and the zipper on the upper row still can be kept in
a closed slate; and after being heated, by taking out the
steaming/cooking bag and opening the zipper on the upper row, the
foodstuff can be served immediately.
[0007] The tear-off strip is made of a low-temperature heat-sealing
material and can be sealed with the bag body well with heat; and
the bag body can be torn open easily; one end of the tear-off strip
is subjected to heat-sealing and reinforcement treatment; after the
tear-off strip is torn open, the tail end of the tear-off strip
still can be firmly kept on the bag body; hence, people cannot
readily discard the tear-off strip being torn off, thus providing
users with convenience while preventing environmental
pollution.
[0008] The male strips and the female grooves are sealed with heat
or glued or ultrasonically adhered on the bag body through the two
thin films respectively.
[0009] The bag body at the upper parts of the zippers is provided
with a laser line; a pull-apart opening is formed at the tail end
of the laser line; and through tearing open along the laser line
from the pull-apart opening, the content can be taken out.
[0010] The second technical scheme: a microwave oven
steaming/cooking bag for prepackaged foodstuff, wherein two rows of
male strips and female grooves meshed with each other are arranged
at opposite positions in a bag body, the male strips and the female
grooves are connected onto the bag body through two thin films
respectively; at least one exhaust hole is formed in the thin film
either between the male strips or between the female grooves or
between one male strip and one female groove at one side of the bag
body; two laser lines are formed in the positions at two sides of
the exhaust hole and on the bag body above the exhaust hole; and
the bag body on the middle parts of the laser lines can be torn
open along the laser lines to expose out the internal exhaust
hole.
[0011] The open strength of a zipper above the exhaust hole is 80
N/50 mm, and the open strength of the zipper below the exhaust hole
is 30 N/50 mm. The male strips and the female grooves are sealed
with heat or glued or ultrasonically adhered on the bag body
through the two thin films respectively; the bag body at the upper
parts of the zippers is provided with a laser line; a pull-apart
opening is formed in the tail end of the laser line; and through
tearing open along the laser line from the pull-apart opening, the
content can be taken out conveniently.
[0012] The microwave oven steaming/cooking bag for the prepackaged
foodstuff disclosed by the invention has the following beneficial
effects: a tear-off strip or a plastic thin film is adhered on the
upper surface of the exhaust hole, so when the content is
prepacked, the content cannot be exposed to the outside and while
the bag is moved or placed for a long period of time, infiltration
of impurities or airborne bacteria from the position of the hole is
prevented, thus prolonging the shelf life of the foodstuff; the
tail end of the tear-off strip is subjected to reinforcement and
heat-sealing treatment, so that the tear-off strip can be fixed on
the bag body relatively well; when torn open, the tail end can
still be firmly kept on the bag body; hence, people cannot readily
discard the tear-off strip being torn off, thus providing users
with convenience while preventing environmental pollution.
