1. Field of the Invention
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.
2. Description of the Prior Art
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.
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.
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.
This invention will be better understood by referring to the accompanying drawings, wherein:
A preferred embodiment of a sealing cap 1 in the present invention, as shown in
In using the sealing cap 1, referring to
Next, the sealing cap 1 can be used for preserving cool food, as shown in
Further, the sealing cap 1 can be used for sealing a microwave container 4, as shown in
The sealing cap according to the invention have the following advantages, as can be understood from the aforesaid description.
1. It can effectively prevent the moist and taste of the food stored in a container from dispersing out.
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.
3. It can preserve the original taste of liquor, soda pops, fruit juices or other refreshments stored in a container.
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.
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.
