Sealing cap
Abstract
A sealing cap includes radial wave-like stripes on an upper
surface, a pull hole and an extended-out rod projections formed on
one side, a brim formed on the other side of the pull hole and
ridges formed on an inner surface of the annular circumferential
vertical wall. The thickness of the stripes gradually becomes
thinner from the outer circumference to the center. In using, a
user holds the pull hole with fingers inserted therein, and with
the other hand pulling the brim down to seal the sealing cap on a
container. Then the moist and taste of the food stored in the
container can be prevented from dispersing out. In addition, the
sealing cap cannot be broken in handling process of sealing by
means of the elasticity produced by the structure of the stripes
with its thinness gradually becoming thinner from the outer
circumference to the center.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a sealing cap, particularly to one
provided with radial wave-like stripes formed on an upper surface
of the cap body, a pull hole and an extended-out rod projection
formed on one side of the sealing cap, and a brim on the other
side. The sealing cap further has a plurality of ridges on an inner
surface of the annular circumferential vertical wall, and the
thickness of the stripes gradually becomes thinner to the center.
In handling for using the sealing cap, a user holds the pull hole
with fingers, places the cap on a container, with one hand pulling
the brim down to seal the upper opening of a container, preventing
the moist or taste of the food stored in the container from
dispersing out. In addition, the sealing cap has expansibility for
stretching during handling process for sealing to save manual force
needed in the handling, and protecting the sealing cap from easily
broken.
[0003] 2. Description of the Prior Art
[0004] In order to keep food from deteriorating in the quality by
soaking moist or by air, food is generally refrigerated or kept
cool, or sealed in a container, separating the food from air or
moist and also preventing it from smeared by small insects such as
ants, cockroaches, flies, mosquitoes, etc. or from losing its taste
and smell. But this method of food preserving can easily let food
lose moist and its taste. Especially, in case of liquor, fruit
juices, soda pops, or refreshments stored in bottles, they will
deteriorate or lose taste quite easily after kept for a while in
case of not totally drunk up. Moreover, when paints containing
solvents, glue, wax, or other industrial materials sealed in
bottles or cans are only half used, the rest of them are hard to
store, with solvents extremely easily volatilize, solidity or
deteriorate.
SUMMARY OF THE INVENTION
[0005] This invention has been devised to offer a sealing cap
having excellent effect for sealing a container storing food so as
to prevent the food in the container from deteriorating to lose
good taste and smell.
[0006] The feature of the invention is a plurality of wave-like
stripes formed on the upper surface of the sealing cap, and a pull
hole and an extended-out rod projection formed in one side of the
cap, a brim on the other side of the pull hole, and a plurality of
ridges formed on an inner surface of the annular circumferential
vertical wall, with the thickness of the stripes gradually becoming
thinner from the outer circumference to the center.
BRIEF DESCRIPTION OF DRAWINGS
[0007] This invention will be better understood by referring to the
accompanying drawings, wherein:

sealing cap in the present invention;
[0011] FIG. 4 is a perspective view of a second process of using

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] A preferred embodiment of a sealing cap 1 in the present
invention, as shown in FIGS. 1-4, is made of high polymer
elastomer, including a cap body 1A, a plurality of radial wave-like
stripes 10 formed on an upper surface of the cap body 1A, a pull
hole 11 formed in one side of the sealing cap 1, and an
extended-out rod portion 110 extending out of the pull hole 11, a
brim 12 formed at the other side of the pull hole 11, a plurality
of ridges 13 formed on an inner surface of the annular
circumferential wall. Then the thickness of the outer circumference
14 is thicker than that of the center 15 and gradually becoming
thinner and thinner from the outer circumference 14 to the center
15, with the wave-like stripes 10 become gradually smaller from the
outer circumference 14 to the center 15.
[0015] In using the sealing cap 1, referring to FIGS. 1, 3 and 4, a
user inserts fingers in the pull hole 11, places the container body
1A of the sealing cap 1 on a container 2 for paint, tea, sugar,
condiments, dry fruits, or a microwave container, and holds the
brim 12 with the other hand and pushes the sealing cap 1 down to
seal the upper opening of the container 2. Thus, the taste and
smell of the food stored in the container 2 cannot disperse out of
the container 2, and the sealing cap 1 cannot be broken because of
the outer circumference 14 of the cap body 1A is thicker than that
of the center portion. Moreover, the elasticity of the sealing cap
1 enables its handling easy with less manual force.
[0016] Next, the sealing cap 1 can be used for preserving cool
food, as shown in FIG. 5, by sealing the sealing cap 1 on a salad
bowl 3 after vegetables and fruits (A1) are put in a salad bowl 3,
with ice cubes (A2) put on the upper surface of the sealing cap 1,
and with another sealing cap 1 sealed on the first sealing cap 1
sealed on the salad bowl 3. So the low temperature of the ice cubes
may gradually be transmitted down in the food in the container 2 to
keep cool the food therein, and the ice water may not flow into the
container, blocked by the first sealing cap 1.
[0017] Further, the sealing cap 1 can be used for sealing a
microwave container 4, as shown in FIG. 6, by sealing the sealing
cap 1 on a microwave container 4, with the extended-out rod portion
110 bent to be laid on the inner surface and sandwiched between the
upper edge of the container 4 and lower surface of the sealing cap
1. Then there is formed a gap between the upper edge of the
microwave container 4 and the sealing cap 1, releasing hot air
inflated by heat from the sealing cap 1.
[0018] The sealing cap according to the invention have the
following advantages, as can be understood from the aforesaid
description.
[0019] 1. It can effectively prevent the moist and taste of the
food stored in a container from dispersing out.
[0020] 2. The structure of the radial wave-like stripes on the
upper surface of the sealing cap can prevent it from broken during
handling it for sealing a container, because the thickness of the
stripes on the outer circumference is thicker than the center and
gradually becoming thinner to the center, producing some elasticity
to the sealing cap.
[0021] 3. It can preserve the original taste of liquor, soda pops,
fruit juices or other refreshments stored in a container.
[0022] 4. It can be used for sealing a container stored with
chemicals, having characteristics of acid-resistance,
alkali-resistance, and high elasticity, possible to prevent them
from volatilizing or deteriorating so that the not-used portion can
be kept for later use, without need of discarding freely to cause
environmental pollution.
[0023] While the preferred embodiment of the invention has been
described above, it will be recognized and understood that various
modifications may be made therein and the appended claims are
intended to cover all such modifications that may fall within the
spirit and scope of the invention.
