Description

[0001] The present invention relates to a sealing cover for a container,

The present invention relates to a sealing cover for a container which is easy to open, and more particularly to a sealing cover which can be detached from a container without being broken when peeled from the container.

Glass or PET is generally used as a food container having a mouth. In the case of using PET as the material of the container, the sealing cover for sealing the opening of the container is made of a plurality of layers of films, and is strongly bonded to the opening of the container by heat sealing for airtightness.

Fig. 8 is a photograph showing a state in which a sealing cover attached to an opening of a container made of PET according to the related art is opened. As shown in Fig. 8, the sealing cover is difficult to fall off from the opening of the container, and particularly when a part starts to tear, it spreads and the sealing cover remains in a dirty form in the opening of the container. Therefore, the user is inconvenient to eat the food in the container in this state, and the food may touch the remaining sealing cover, thus causing a sanitary problem.

Registration Utility Model No. 20-0396261

The object of the present invention, which is devised to solve the above-mentioned problems, is to provide a sealing cover which can be detached from the container without being broken when peeled from the container.

According to an aspect of the present invention, there is provided a method of manufacturing a semiconductor device, comprising the steps of: forming a sealing layer in contact with a container; an adhesive layer disposed on the sealing layer; an aluminum layer disposed on the adhesive layer; a foam layer disposed on the aluminum layer; Wherein the foam layer and the surface layer are uniaxially stretched films and the orientation direction of the foam layer and the surface layer coincide with each other.

In addition, at least one handle disposed parallel to the orientation direction of the foam layer and the surface layer is formed. The foam layer may have a through-hole at the center thereof.

Further, a reinforcing layer is interposed between the foam layer and the aluminum layer. The reinforcing layer may be formed with a through-hole at the center thereof.

Further, a reinforcement net is interposed between the foam layer and the aluminum layer.

Through this design, the sealing cover can be cleanly opened from the container, so that not only hygienic but also the perfection of the product can be raised, thereby increasing the trust of the consumer.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings, the same reference numerals will be used to designate the same or similar components in the drawings, unless they are indicated on other drawings. Detailed descriptions of known functions and configurations are omitted.

1 and 2, reference numeral 10 denotes a sealing cover according to Embodiment 1 of the present invention. The sealing cover 10 comprises five film layers.

A sealing layer 12 in contact with the container 1; an adhesive layer 14 disposed on the sealing layer 12; an aluminum layer 16 disposed on the adhesive layer 14; And a surface layer 20 disposed on the top of the foam layer 18 and exposed to the outside.

The sealing layer 12 may be made of the same material as the container 1 so as to facilitate bonding with the container 1. Therefore, when a PET container is used, a PET film is used.

The adhesive layer 14 functions to adhere the aluminum layer 16 and the sealing layer 12 to each other and may be made of low molecular weight polyethylene. The aluminum layer 16 may be made of aluminum foil or aluminum foil.

The foam layer 18 may be foamed polyolefin foam. When the sealing cover 10 is sealed to the container 1, it is sealed to the pressure and heat transmitted to the surface layer 20. At this time, the foam layer 18 serves as a cushion and transmits pressure and heat to the sealing layer 12. However, in the sealing cover 10, the foam layer 18 tears and the opening of the sealing cover 10 as a whole fails.

In the present invention, in order to solve this problem, as shown in FIG. 1, the surface layer 20 and the foam layer 18 are arranged in alignment. At this time, the surface layer 20 and the foam layer 18 are uniaxially stretched. The stripes shown in the surface layer 20 and the foam layer 18 in Fig. 1 indicate uniaxial stretching. The uniaxial stretching refers to a film obtained by stretching an unoriented film extruded from a circle or a T-die to orient the polymer in the uniaxial direction.

As a result, the surface layer 20 and the foam layer 18 coincide with each other in the tearing direction, so that the uniaxial oriented film tends to be torn in the alignment direction. 2, the direction of the knobs 22 and 24 and the orientation direction of the surface layer 20 and the orientation direction of the foam layer 18 are made parallel to each other, and the direction in which the user opens the sealing cover 20 Is always the alignment direction of the surface layer 20 and the foam layer 18.

It is also possible to print the opening direction on the surface layer 20 instead of the knobs 22 and 24.

As a result, the sealing cover 10 can be opened from the container 1 cleanly, as shown in Fig.

Next, the sealing cover 30 according to the second embodiment of the present invention will be described with reference to FIG. The sealing cover 30 is basically the same as the sealing cover 10 of the first embodiment except that a reinforcing layer 32 is disposed between the aluminum layer 16 and the foam layer 18. The reinforcing layer 32 may have a through-hole at the center thereof.

The reinforcing layer 32 functions to reinforce the bonding portion of the foam layer 18 so as to maintain the bonding portion without tearing, and a material such as PET can be used. Of course, the reinforcing layer 32 is also preferably aligned with the orientation direction of the surface layer 20 and the foam layer 18. As a result, the foam layer 18 can be opened without being torn when peeled from the container 1 by the interaction of the surface layer 20 and the reinforcing layer 32.

The sealing cover 40 according to the third embodiment of the present invention will now be described with reference to Fig. The sealing cover 40 is basically the same as the sealing cover 10 of the first embodiment, but a through-hole is formed at the center of the foam layer 42. As a result, the area of the foam layer 42 is considerably reduced as compared with the sealing cover 10 of the first embodiment. Therefore, even when the sealing cover 40 is opened, the possibility of the tearing of the foam layer 42 is reduced, and even if a partial tearing occurs, the tear can not propagate to the through-hole side, So that it can be helpful for opening.

The sealing cover 50 according to the fourth embodiment of the present invention will be described with reference to Fig. The sealing cover 50 basically complements the sealing cover 30 of the second embodiment and inserts the reinforcing net 52 in place of the reinforcing layer 32. [ The reinforcing net 52 is a fiber screen made of a polymer such as polyester. Therefore, when the sealing cover 50 is opened, the foam layer 42 is caught by the reinforcing net 52, and the possibility of tearing is drastically reduced. Even if a partial tearing occurs, the fabric structure of the reinforcing net 52 So that the tear can not be propagated. As a result, the sealing cover 50 can be reliably and cleanly separated from the container 1.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention as defined in the appended claims. It can be understood that
