Description

Telescopic sealing cover

This creation is related to the sealed box and the cover. In more detail, it is a type that can tightly close the sealed box/can and can change the capacity of the sealed can by up and down, and can be separately removed and used as a container. Seal the cover.

According to the conventional sealed can, the sealing can comprises a can body and a sealing cover. The sealing cover can be tightly plugged or locked in the can of the can body. There are many related products or patents, which are not described here. The sealed cans can make the food in the tank really block from the outside world and get the effect of preserving fresh food. Therefore, it is deeply loved by consumers and is a must-have household kitchen utensil for every household.

Since the sealed can has a certain capacity and volume, if the amount of food to be contained is slightly larger than the capacity of the sealed can, the remaining food has to be accommodated in another sealed can, and it also occupies a storage space of a sealed can. A shortcoming that needs to be improved.

In view of the above situation, the creator invested a lot of time to research relevant knowledge, and compared various advantages and disadvantages, research and development of related products, and after many experiments and tests, finally launched a "retractable sealing cover" to improve the above. Missing to meet the needs of the public.

The main purpose of this creation is to provide a telescopic sealing cap that not only has the basic function of tightly closing the sealed box/can, but also can be flexibly changed to change the capacity of the sealed box/can, or removed from the sealed canister as a container. Very practical value.

Therefore, in order to achieve the above purpose and effect, the present invention provides a telescopic sealing cover for covering the can of the sealed box/can, comprising a fixing section and a telescopic section connected with the fixing section; the fixing section An opening is provided for being coupled to the can of the sealed box/can. The telescopic section is formed of an elastic material and has a retractable shell shape, and a cover bottom is formed at one end of the corresponding opening, and can be subjected to force Elongation or condensation of the forward or reverse sides to create a receiving space between the opening and the bottom of the cover.

Further, the bottom side ring of the fixing section is provided with a joint portion for the fixing section to be sleeved on the can of the sealed box/can.

Further, the joint may be one of a groove or a convex surface.

Further, the upper ring of the telescopic section is provided with adjacent plurality of inner creases and outer creases for forming the plurality of loops.

Further, the outer diameter of the telescopic section is a conical shell shape which tapers from the opening toward the bottom of the cover.

Further, when the telescopic section is extended toward the sealed box/can, the upwardly facing storage space can provide the function of accommodating other articles and food, and the telescopic section is covered. When the seal box/can is extended outside, the capacity of the sealed can is increased.

Further, the fixing section and the bottom of the cover may be formed in a circular shape and a rectangular shape. Or one of the other shapes for a sealed box/can that can be closed to a circular, rectangular or other shape.

The fourth and fifth figures are diagrams showing the state of use of a preferred embodiment of the present invention, showing the state in which the telescopic sections are stretched in different directions.

Fig. 6 is a view showing the state of use of another preferred embodiment of the present invention, showing a state in which the stretchable section is stretched toward the inside of the sealed case.

In order to enable your review committee to have a better understanding and recognition of the features and characteristics of this creation, the following several preferred embodiments are listed below with the following description: Please refer to the first to third figures, this creation The telescopic sealing cover 10 of a preferred embodiment can be used to cover the can 21 of a sealed can 2, and includes a fixing section 11 and a telescopic section 12 connected to the fixing section 11.

The fixing section 11 is substantially annular (other shapes are also possible) and forms an opening 111 on the inner side, and the bottom side ring is provided with a joint portion 112, which may be one of a groove or a convex surface. The can end 21 of the sealed can 2 is slidably fitted.

The telescopic section 12 is made of an elastic material, such as silicone rubber. The outer peripheral ring has an outer plurality of inner folds 121 and outer folds 122, so that the stretchable section 12 can form a plurality of loops 123, and the stretch section 12 has a bottom and a A closed lid bottom 124. Thereby, the telescopic section 12 can be stretched or condensed by force, and a receiving space 13 is formed between the opening 111 and the cover bottom 124, and the receiving space 13 can be elongated and shortened with the telescopic section 12, and Change the size of the space and the position of the bottom 124.

The fixing section 11 and the bottom 124 of the telescopic sealing cover 10 are circular (or rectangular or other shapes), and the groove 112 can be used to cover the can 21 of the circular sealed can 2 . In the normal use state, as shown in the first figure, the telescopic section 12 is condensed and collected in the fixed section 11, and the air is blocked outside the sealed can 2 to achieve the function of keeping fresh and sealing.

In particular, as shown in the fourth figure, when the user wants to hold an item slightly larger than the original capacity in the sealed can 2, the telescopic section 12 can be stretched upward (reverse) so that the cover bottom 124 Located above the fixed section 11, when the telescopic sealing cover 10 is closed to the can 21 of the sealed can 2, the storage capacity of the sealed can 2 can be increased (the capacity of the receiving space 13 is increased), and thus, It can solve the drawbacks of the conventional sealed cans because the capacity is fixed, and the articles beyond the capacity of the sealed cans can only be accommodated in another sealed can and occupy more space.

In addition, as shown in the fifth figure, the user can also push the cover bottom 124 downward (forward), and the telescopic section 12 is stretched downward to form a container such as a cup or a bowl. The space 13 can be used to accommodate the snacks 3 taken out from the sealed can 2, and it is environmentally friendly without waste of toilet paper or paper to hold snacks. Of course, the telescopic sealing cover 10 can also be used separately from the sealed can 2, and since the cover bottom 124 can be stably supported on a plane, the expansion and contraction The sealing cover 10 can be used as a cup or a bowl for the purpose of accommodating food and tea.

In addition, the fixing section 11 and the cover bottom 124 of the telescopic sealing cover 10 can also be formed in a rectangular shape, as shown in the sixth figure, and can be correspondingly closed to the rectangular sealed box 3, which can also be exposed. The functions, such as the capacity of the sealed box 3, or the container used for accommodating food, tea or soup, can avoid the disadvantages of using toilet paper to put food waste paper, and can prevent the food from being randomly placed on the table. The situation happened.

In summary, the retractable sealing cover provided by the present invention has a simple structure and can be extended or shortened by force, thereby not only obtaining the sealing effect of tightly sealing the sealed box/can, but also by using the telescopic section. The method of stretching or shortening, changing the capacity of the sealed box/can or the contents, can be taken separately as a container, providing a variety of ways of use and various functions, and can completely solve the drawbacks of the use and achieve the intended purpose of the creation. . The above description is only a preferred embodiment for explaining the present creation, and is not intended to impose any form limitation on the creation, so that any modification related to the creation in the same creative spirit is made. Or the changer, other types that can be implemented according to the same effect, should still be included in the scope of protection of this creative intention.
