CN2855940Y - Sealing film ear opening improved structure - Google Patents

Abstract

The utility model provides an improved structure for opening a sealing film by pulling a lug, which is mainly suitable for sealing films used for sealing the mouths of bottles and jars in a roughly circular shape, and is of course also suitable for sealing the mouths of bottles and jars in other shapes; a base layer is used as a sealing cover and a pull lug layer is arranged thereon, and 1/2 of the pull lug layer is left unsticked and used as a pull lug, which has the advantages of saving effort and being easy to open; and the sealing film of the utility model is easy to seal and block bacteria, and can be continuously sealed by an automated machine, thereby achieving the purpose of improving yield and reducing cost.

Description

Sealing film ear opening improved structure

technical field

The utility model relates to an improved structure for opening the ear of a sealing film.

Background technique

First, please refer to Fig. 1 and Fig. 2, the conventional sealing film 100 has a protruding ear 200 for the user to open, but when the sealing film 100 is capped, the protruding ear 200 must first be moved Fold down or fold back and then make a cover. Assuming that the pull ear 200 is folded back (see Figure 2) and then make a sealing film cover, the folded back of the pull ear is thicker at the pull ear 200. When sealing on a heat sealer, This place often causes the seal not to be tightly sealed, and leakage occurs.

In addition, if the pull ear 200 is folded down (see Figure 1) for sealing, the sealing condition is good, but the pull ear 200 hangs on the thread of the tank mouth. When the outer cover is locked on the thread, the pull ear 200 is squeezed to cause tearing, so the cover at the pull ear 200 will leak.

The above-mentioned various reasons cause the cost to increase, and the problem cannot be eliminated by making simple improvements on the equipment, so the manufacturer has always been troubled, so it must be improved immediately.

Contents of the invention

The purpose of the utility model is to provide an improved structure for opening the ear of the sealing film.

The technical solution adopted by the utility model is: an improved structure for opening the ear of the sealing film, which is a film suitable for sealing bottles and cans. Leave 1/2 unconnected with the base layer, so that the unconnected part can be used as a pull ear, which has multiple purposes of labor saving, easy opening, and easy sealing.

After the utility model is sealed, there is no gap, so that the objects in the bottle are guaranteed to be isolated from air and bacteria.

The utility model is easy to seal, has no gap, and can be continuously sealed by automatic machinery, so as to achieve the purpose of improving yield and reducing cost.

Detailed ways

A preferred embodiment will now be described in detail with reference to the accompanying drawings.

First please refer to Fig. 3, Fig. 4 and Fig. 5, the utility model is an improved structure for opening the sealing film ear. Of course, it is also suitable for sealing bottles and cans of other shapes. The utility model uses the base material 1 as the sealing connection layer, which is a material that can withstand high temperatures, is easy to seal, and does not deform. There is an ear layer 2, and the area of the ear layer 2 that is connected to the base material 1 is about 1/2. The parts together can be used as pull ear 4;

The above-mentioned opening structure 5 formed by the sealing film pull ear is evenly sealed without air leakage, so that the contents in the container 6 can be preserved, and when opened, it is pulled up by the pull ear 3. Refer to Figure 6 and Figure 7, which has the advantages of labor saving and easy opening. And it has multiple purposes of being easy to seal.

In summary, it is a preferred embodiment of the present utility model, and should not limit the scope of implementation of the present utility model with this, that is, all equivalent changes and modifications made according to the patent scope of the utility model and the contents of the creation instructions should be Still belong to the scope that the utility model patent covers.

Claims (1)

1. An improved structure for opening the sealing film ear, characterized in that: comprising: The bottom base material is a sealing connection layer, and a lug layer is connected to the base base material. The area of the lug layer covering the connection on the base base material is at 1/2, and the remaining parts are not connected together, so that the The part of the lug layer that is not connected together can be used as a lug.
