Description

Sealing cap with fixed sealing paper function

The invention relates to a sealing cover, in particular to a cover body capable of sealing the opening of the can body.

Generally, the container can be filled with various foods, and usually has a cover covering the opening of the container to isolate the air, to achieve the packaging or to extend the storage time of the internal food, but the connection between the container and the cover is only The simple cover design still does not completely isolate the internal food from contamination.

In order to be able to surely isolate the food in the container from the outside air, one of the methods is to provide an aluminum easy-opening cover between the container and the cover body, and the structure comprises an easy-opening cover and a pull ring, but the method is not only costly. And after opening, it will not be able to effectively seal again, resulting in a significant reduction in the shelf life of subsequent foods.

Therefore, the applicant has proposed, as disclosed in Patent Document 1, that a sheet body is disposed between the can body and the lid body, and a colloid is provided around the bottom surface of the sheet body so as to be adhered to the opening of the can body and to achieve repeated pasting. However, in the combination of Patent Document 1, the sheet body is first adhered to the opening of the can body, and then the lid body is smashed, not only the entire process needs to be completed through two processes, but also when the sheet is attached to the opening. It must be aligned accurately, and if it is offset, it must be re-adhered, and the overall time is less costly.

In view of this, how to provide a solid that can be improved against the above-mentioned defects The sealing cover of the sealing paper function has become a subject to be improved by the present invention.

More preferably, the cover body (1) has an inner wall surface further provided with at least one bottom surface of the flange portion (a2) of the can body (A) so that the cover body (1) and the can body (A) is a snap-fit portion (14) that is snap-fitted.

More preferably, the colloid (21) of the sealing sheet (2) has a width smaller than the pressure sealing portion (13).

More preferably, the can body (A) is a PET material can body.

Compared with the prior art, the effects and effects of the present invention are as follows:

The first point: in the present invention, the sealing piece (2) is directly disposed in the cover body (1), In order to form a combination, the structure can not only accurately align with the opening (a1) of the can body (A), but also save assembly between the cover body (1), the sealing piece (2), and the can body (A). Time, the effect of practicality and convenience, in line with market demand.

Second point: In the present invention, when the cover body (1) is covered downward at the opening (a1) of the can body (A), the sealing piece (2) is in contact with the flange portion of the can body (A) (a2) After the top surface, the peripheral edge is detached from the position of the fixed sealing portion (12), and the sealing member (13) can be surely adhered to the can body (A) by the effect of pressing down the sealing portion (13).

Fig. 6 is a partially enlarged cross-sectional view showing the fifth drawing.

Hereinafter, the following is a detailed description of the embodiment shown in the drawings: as shown in FIG. 1 to FIG. 3, the figure discloses a sealing cover having a function of a fixed sealing paper, which can seal a can body (A). The opening (a1) is provided with a flange portion (a2) at the outer periphery of the opening (a1), characterized in that the sealing cover (100) having the function of fixing the sealing paper comprises a cover body (1) And a piece of the mouth piece (2); the cover body (1) has a groove (11) at the bottom surface thereof corresponding to the opening (a1) of the can body (A), and the inside of the groove (11) The wall surface is convexly arranged in a ring shape The sealing portion (12) is fixed, and a pressing sealing portion (13) is disposed on the inner bottom surface; the sealing sheet (2) has a peripheral edge connected to the fixing sealing portion (12), and the bottom surface is provided There is a colloid (21) corresponding to the top surface of the flange portion (a2) of the can body (A).

Among them, the sealing cover (100) having the function of fixing the sealing paper by the design, as shown in Fig. 3, is to directly provide a groove (11) in the cover body (1), and in the groove ( 11) A fixing sealing portion (12) is arranged around the inner wall surface, so that the periphery of the sealing piece (2) is just inserted therein, so that the cover body (1) and the sealing piece (2) form a combined shape.

Next, the present invention can be implemented in combination with the can body (A) as shown in Figs. 4 to 5, and when the lid body (1) is covered downward at the opening (a1) of the can body (A), please refer to As shown in Fig. 6, after the sealing piece (2) contacts the top surface of the flange portion (a2) of the can body (A), the peripheral edge of the sealing piece (2) is detached from the position of the fixed sealing portion (12), and The top surface of the sealing piece (2) is in contact with the pressure sealing opening portion (13), and the sealing piece (2) can be adhered to the can body (A) through the colloid (21) by the effect of pressing the sealing portion (13). The flange portion (a2) is a result of mutual assembly between the lid body (1), the sealing sheet (2), and the can body (A).

Therefore, compared with the prior art, the novel structure not only saves a combined process, but also allows the sealing piece (2) to be aligned with the opening (a1) of the can body (A) without offset. In order to achieve the convenience of combination, save time and cost, in line with market demand.

In the above, the cover body (1) is further provided with at least one bottom surface of the flange portion (a2) of the can body (A) so that the cover body (1) and the can body (A) ) is a snap-fit portion (14) that is snap-fitted.

In the design of the fastening portion (14), as shown in Fig. 6, the cover body (1) can be connected to the can body (A) in a clamping manner, thereby achieving stability and difficulty in the tank body (A). ) the effect of separation.

In the above, the colloid (21) of the sealing sheet (2) has a width smaller than that of the pressure sealing portion (13).

In order to allow the sealing piece (2) to be stably attached to the flange portion (a2) of the can body (A), as shown in Fig. 6, the width of the colloid (21) needs to be smaller than that of the pressure sealing opening portion (13). Width, when the cover (1) is pressed down, the colloid (21) can achieve a complete fit.

In the above, the can body (A) is a PET material can body.

Among them, PET is called polyethylene terephthalate, which is a thermoplastic polyester with excellent toughness, tensile strength, impact strength, wear resistance and electrical insulation, and has good toughness, light weight and no Breathable, acid and alkali resistant, water resistant, oil resistant, etc., in recent years, it has become a common container for soda, juice, carbonated beverages, edible oil retail packaging, etc. Therefore, the tank body (A) is better in manufacturing, and the PET material is preferred.

The structure, features and effects of the present invention are described in detail above based on the embodiments shown in the drawings. Since the novel and progressive requirements are met, a new patent application is filed according to law; however, the above description is only a preferred embodiment of the present invention. However, the present invention is not limited to the scope of implementation of the present invention, and therefore modifications that are in accordance with the meaning of the present invention are intended to fall within the scope of the present invention as long as they are within the scope of the present invention.
