Description
FIELD OF TECHNOLOGY
[0001] The present invention relates to storage apparatus for food
and jewelry of family, and pertains to the household field, in
particular relates to a re-useable vacuum storage bag with exhaust
valve and pressure-sealing zipper.
BACKGROUND
[0002] Vacuum food storage bag has been accepted and used widely by
consumers due to a demand on the quality of people's life and food
sanitation. But the average family cannot afford to buy such vacuum
bag because it is expensive and consumable.
[0003] Some re-useable vacuum pressure-sealing plastic bags with
exhaust valves and zippers have been appeared on the market, but
their pressure-sealing effect is unreliable and temporary due to
its inexperienced technique and structure, and customers don't
intend to buy such product continuously and many responses from
them are negative. For such existing product, in which especially
the exhaust valve is complicated, the product's structure is that
basically the upper and lower plastic films clamp the plastic bag,
and a soft valve plate is placed in the center hole thereof so as
to attain the exhaust and seal function, such plastic bag is mainly
handmade currently with high cost.
[0004] In addition, the pressure-sealing effect would be weakened
or disappeared due to the dust entering sealing surface in actual
use, since the sealing for the above mentioned plastic bag is in
the manner of a plane sealing and lacks of air filtration device.
Therefore, there is a strong demand for a vacuum storage bag that
could be re-useable and low cost
SUMMARY
[0005] It is an object of the invention to provide a vacuum storage
bag featuring reliable and durable sealing efficiency, simple
structure, low cost, mechanized producing and being re-useable.
[0006] To achieve the above object, the present invention employs
the following technical solutions:
[0007] A vacuum pressure-sealing storage bag with exhaust valve and
pressure-sealing zipper comprises plastic bag films, an exhaust
valve and a pressure-sealing zipper. The exhaust valve comprises a
valve plate, valve seat and valve cover. The valve plate is
configured between the valve seat and the plastic bag film being
bonded to the valve seat. An air duct is configured between the
valve seat and inner surface of the valve cover.
[0008] The valve plate is made of soft polymer, and is disposed
between the plastic bag film and the valve seat, wherein a raised
cone head is provided in the center position of the valve plate,
and is configured to mate with a conical boring of the valve seat
in a sealing relationship. During air exhaust, the cone head of the
valve plate will be raised slightly under the exhaust pressure, and
the air inside can be exhausted through the duct. When air exhaust
is done, the cone head of the valve plate will be attached tightly
to the conical boring of the valve seat under the negative air
pressure.
[0009] One surface of the the valve seat is bonded to inner surface
of the plastic bag film. Numerous grooves and convex ribs are
spread over the other surface of the valve seat, and are wrapped
tightly by the valve cover, whereby a narrow and winding air duct
is formed by the grooves and convex ribs together with inner
surface of the valve cover.
[0010] The pressure-sealing zipper is provided at an opening of the
plastic bag with exhaust valve, and these bags could be re-useable
without damaging bags.
[0011] The present invention has the following advantageous effects
as compared with to the prior art: [0012] 1. The sealing efficiency
of the plastic bag of the invention is reliable and durable, the
cone head of the valve plate is fitted tightly with the valve seat,
and could resist the actions, such as the pushing or pulling or
squeezing or shocking force applied to the plastic bag by external
force, to prevent air leakage; [0013] 2. Goods containing dust and
impurities could be packed by the plastic bag of the present
invention with excellent sealing efficiency, because the air can be
filtered by the exhaust valve, the dust can be prevented from
entering sealing surface of valve plate; [0014] 3. The exhaust
valve of the plastic bag of the invention is bonded firmly to inner
surface of the plastic bag film, and such one-sided combination
structure is suitable for a mechanized mass production in order to
save cost.

DETAILED DESCRIPTION
[0029] The invention is explained in detail in the following with
reference to the drawing:
[0030] As shown in FIG. 1, a vacuum pressure-sealing storage bag
with exhaust valve and pressure-sealing zipper comprises a plastic
bag film 10, exhaust valve 20 and pressure-sealing zipper 40. As
shown in FIGS. 2 and 3, the exhaust valve 20 disposed at the
opening of the bag comprises a valve plate 21, a valve seat 22 and
a valve cover 23. The exhaust valve 20 is provided between the
upper film and lower film of the plastic bag.
[0031] One surface of the valve seat 22 is bonded firmly to inner
surface of the plastic bag film 10. Numerous grooves 221 and convex
ribs 222 are spread over the other surface of the valve seat 22,
and are wrapped tightly by a valve cover 23, so that such structure
can produce a narrow and winding air duct 30, which will filter the
air passed therein, and will prevent the duct from entering sealing
surface of the valve plate to improve the sealing reliability of
the plastic bag.
[0032] The valve plate 21 is made of soft polymer, wherein a raised
cone head is provided in its center position, and is configured to
mate with a conical boring of the valve seat to form a reliable
sealing surface. The valve plate 21 is configured between the valve
seat 22 and the plastic bag film 10 being bonded to the valve seat
22. During air exhaust, the cone head 211 of the valve plate will
be raised slightly under the exhaust pressure, and the air inside
can be exhausted through the duct 30. When air exhaust is done, the
cone head 211 of the valve plate will be attached tightly to the
conical boring of the valve seat again under the negative air
pressure.
[0033] A pressure-sealing zipper 40 is provided at the opening of
the bag with the exhaust valve 20, whereby goods could be picked
out or put in the bag, such structure could be re-useable without
damaging the plastic bag.
[0034] The vacuum storage bag of the present invention could be
re-useable and avoid waste. The narrow air duct formed by the
grooves of valve seat and the valve cover could filter the air
inside the bag, to prevent the dust from entering sealing surface
between the valve plate and the valve seat; The cone head of the
valve plate ensures its sealing reliability further. The present
invention is adapted for household, restaurant and outdoor
activities, food and jewelry could be vacuum packed with
vacuum-pumping equipment.
[0035] The description mentioned above is the preferred embodiment
of the invention, not for purposes of limitation. Therefore, any
simple modifications and equal variations to the above embodiment
according to the technical substance of the invention, falls within
the scope of the appended claims.
