Abstract

A packaging can with a plastic film and metal composite end cover belongs to the field of packaging containers. It includes a sealed end cover (2) connected to a can body (1), and is characterized in that an observation window is provided in the middle of the end cover (2), and a transparent film (3) is arranged on the observation window, and the transparent film is tightly rolled and pressed together with the sealed end cover. Since the observation window is arranged on the end cover at one end of the packaging can or barrel, it is convenient for commodity buyers to observe and understand the quality and condition of the packaged goods in the container. At the same time, since the metal end face fracture parts of the can body and the end cover are not in contact with the liquid in the container, the can body and the end cover will not be corroded by the liquid in the container, which is conducive to extending the service life of the packaging can and the warranty period of the goods in the container. In addition, the end cover and the transparent film and the end cover and the can body are both connected by flanging and rolling, and the overall sealing performance is good. The utility model can be widely used as a packaging container for solid, powder or liquid products in the food, chemical, coating and other industries.

Description

Plastic film metal combination end cap packaging cans

technical field

The utility model belongs to the field of packaging containers, in particular to a packaging can.

Background technique

Announcement date May 22, 2002, the Chinese patent of announcement number CN2492481 discloses a kind of container box with viewing window, can allow the article that is contained in the container box to show in front of the eyes, and make it convenient for consumers to open it without opening it. You can view the items you want to buy without removing the lid of the box. But when the content in the packaging container is a water-based liquid (such as water-based latex paint, paint, etc.), the end face fracture part of its metal flange is easily corroded under the erosion of the moisture contained in the liquid. At the same time, this kind of corrosion will pollute the goods contained in tanks and barrels, affect the quality and appearance of the goods, and seriously restrict the product quality and warranty period of water-based liquid goods.

Utility model content

The purpose of the invention of the utility model is to provide a packaging tank with a plastic film and metal combined end cover with good corrosion resistance and good sealing performance.

The technical scheme of the utility model is: to provide a plastic-film-metal composite end cap packaging tank, including a sealed end cap 2 connected to the tank body 1, characterized in that: an observation window is set in the middle of the end cap 2, and a transparent film 3 is set on the observation window , The transparent film and the sealing end cap are tightly rolled and pressed together.

Wherein the edge 4 of the observation window is turned up or down, and the transparent film 3 and the sealing end cover 2 body are tightly rolled and pressed together; the length of the turned-up of the edge 4 of the observation window exceeds one week.

Compared with the prior art, the utility model has the advantages of:

1. The broken part of the metal end surface of the can body and end cap is not in contact with the liquid in the container, so the can body and end cap will not be eroded by the liquid in the container, which is beneficial to prolong the life of the packaging can and the warranty period of the goods inside.

2. Both the end cap and the transparent film and between the end cap and the tank body are connected by flanging and crimping, with good sealing performance and firm connection.

3. Through the transparent film, consumers can directly observe the contents to prevent counterfeiting.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

Fig. 1 is a schematic structural diagram of an embodiment of the utility model; Fig. 2 is a schematic structural diagram of another embodiment of the utility model; Fig. 3 is a view from the direction A of Fig. 1 .

Detailed ways

In Fig. 1 and Fig. 2, an observation window is provided in the middle part of the sealing end cap 2 connected with the tank body 1, and a transparent film 3 is arranged on the observation window, and the edge 4 of the observation window is flanged upwards or downwards, and the transparent film 3 is connected with the sealing end cap 2 The body is tightly crimped and combined; the length of the flanging of the observation window edge 4 exceeds one week. Its transparent film 3 can be soft transparent plastic film or hard transparent plastic sheet.

FIG. 3 is a top view of FIG. 1 .

Since an observation window is arranged on the end cap at one end of the packaging can or barrel, it is convenient for commodity buyers to observe and understand the quality and condition of the commodities packaged in the container. At the same time, since the metal end fracture parts of the can body and the end cap are not in contact with the liquid in the container, the can body and the end cap will not be eroded by the liquid in the container, which is beneficial to prolong the life of the packaging can and the warranty period of the goods inside . In addition, the connections between the end cap and the transparent film and between the end cap and the can body are crimped and crimped, and the overall sealing performance is good.

The utility model can be widely used as a packaging container for solid, powder or liquid products in industries such as catering, chemical industry and paint.
