Description

Vacuum button indicator cap for flat screwless packaging cans

The utility model relates to a bottle cap, in particular to a vacuum button indicating cap with a flat mouth and no screw teeth for packaging.

Vacuum packaging is one of the main ways to keep food fresh. Regardless of whether it is in a soft bag or a hard bottle, after filling the food into the container, it is sent to the vacuum packaging machine, and the container is processed into a vacuum state and then sealed. Or cover, and whether the container is in a vacuum state, in terms of soft bags, when the bag is vacuumed, the bag body will collapse completely, and the bag body will be closely attached to the food. When air infiltrates, the effect of bag collapse is immediately released, so it is easy to distinguish with naked eyes.

If the container is packed in a hard bottle, even if the inside of the container is vacuum, the container still maintains its complete appearance and will never be deformed. Therefore, the industry has invented a kind of indicating bottle cap. When the inside of the container is vacuum, the center of the bottle cap will That is, it is slightly sunken, as a vacuum indicator.

The above is just a general introduction to vacuum packaging, and regardless of whether hot food or cold food is used to achieve the above-mentioned vacuum purpose, vacuum packaging machines are required, and the purchase, maintenance, and repair of vacuum packaging machines are one of the tasks of the industry. Quite a large cost. And another problem that needs to be solved is that the bottle mouth of the above-mentioned vacuum packaging bottle is sealed by a screw cap, while for the cap body of a flat-mouthed non-thread can, there is always a lack of a bottle cap with a vacuum indicator.

The purpose of this utility model is to provide a vacuum button indicator cover for a flat-mouthed non-threaded packaging can, which mainly uses a metal sheet cover to cooperate with a tight sealing ring to seal the can mouth, and through the filling of the can For high-temperature sterilized food, the vacuum in the tank is achieved by natural cooling, and the center of the lid sinks as an indication.

The purpose of this utility model is achieved in that:

The utility model relates to a vacuum button indicator cover for a flat-mouthed non-screw-teeth packaging can, which includes a bottle container. The edge of the bottle container is sealed with a tight sealing ring. The cover is made of metal sheet, and the inner periphery is filled with annular elastic body; and the outer periphery of the top surface of the cover is horizontal. The first radial edge, the inner edge of the first radial edge is a downward slope; and the inner edge connected to the first radial edge is a second radial edge that slopes upward with a rise, and the second radial edge The height is lower than the first radial edge; the inner edge of the second radial edge is connected to an edge plate with a rise, and an intermediate piece is axially protruded from the center of the edge plate; by the above structure, the bottle After the food in the container is sterilized and cooled naturally, even if the inside of the bottle container is in a vacuum state, the intermediary sheet and edge plate of the cover will be concave, and the naked eye can tell that the inside of the bottle container has reached a vacuum state

Features of the utility model:

The utility model fills the container with high-temperature sterilized food, covers it and cools it in a natural way, and uses the hot air to evaporate to make the inside of the bottle container a vacuum, which saves the use cost of the vacuum packaging machine. The naked eye can tell whether the inside of the bottle is in a vacuum state.

The utility model can also obtain further explanation from following accompanying drawing and embodiment:

Fig. 1 is the three-dimensional exploded view of the utility model.

Fig. 2 is the schematic diagram of the combined appearance of the utility model.

Fig. 3 is a schematic cross-sectional view of the vacuum indicator cover of the present invention.

Figure 4 is a schematic cross-sectional view of the vacuum indicator of the present invention.

Embodiments of the utility model are described in detail below by accompanying drawings:

Please refer to shown in Fig. 1, 2, 3, the utility model mainly has a bottle container 10, and the top of this bottle container 10 is a protruding thick flange 11, and this flange 11 is a flat mouth without screw tooth shape, and this connector A pressing ring 12 is provided on the top edge of the edge 11 near the inner ring;

The edge 11 of the bottle container 10 is used to connect a cover body 20. The cover body 20 is made of sheet metal. The periphery of the cover body 20 has a vertical skirt 201. Then fill in the annular elastic body 22;

The peripheral edge of the cover body 20 is a horizontal first radial edge 21, the inner edge of the first radial edge 21 is inclined downward to a predetermined depth, and the inner edge connecting the first radial edge 21 is a downward direction. A second radial edge 23 that is inclined upwards, and the height of the second radial edge 23 is lower than that of the first radial edge 21; An intermediary piece 25 protrudes axially from the center of the edge plate 24. The cover 20 is attached to the top surface of the edge 11 of the bottle container 10, and the annular elastic body 22 is attached to the pressing ring 12;

The cover body 20 is covered on the bottle container 10, and is ring-sealed on the outer edge surface of the cover body 20 and the connecting edge 11 with a tight sealing ring 30; the tight sealing ring 30 is a ring body made of metal, and its top is radially A lip 31 is bent on the inner arc, and the lip 31 is attached to the outer edge end of the first radial edge 21 of the cover body 20 to limit the position of the sealing ring 30. The sealing ring 30 has two ends 32 , 33, one of the ends 32 has an extended buckle 321, and the buckle 321 has a button hole 322; while the other end 33 is provided with an outwardly warped buckle tongue 331 at the proximal end, when the sealing ring 30 When the lid body 20 and the edge 11 are tightly sealed, the buckle tongue 331 can be stretched and buckled into the button hole 322, so that the tight seal ring 30 is tightly sealed on the lid body 20 and the bottle container 10.

And the principle that the utility model reaches vacuum is mainly limited to the filling and filling of hot food; it is to fill the hot food that has been sterilized at high temperature into the bottle container 10, cover the lid body 20 and seal the tight seal ring 30, In order to seal the opening of the bottle container 10, it can be left to stand and wait for the boiling hot food in the bottle container 10 to cool down in a natural way. Because the hot air evaporates through the bottle container 10 during cooling, there is no gap in the outside air. Entering the state, the pressure in the bottle container 10 will be lower and lower until the boiling hot food has dropped to normal temperature, the hot air in the bottle container 10 will completely evaporate to form a vacuum, and the atmospheric pressure will press the cover body 20 tightly. Closely attached to the edge 11 of the bottle container 10, and the annular elastic body 22 is used to close the gap between the cover body 20 and the edge 11 to achieve a sealing effect; The plate 24 is concave, and the naked eye can tell that the inside of the bottle container 10 has reached a vacuum state;

With the above-mentioned structure and vacuum principle, the flat-mouth screwless packaging can has a practical vacuum indicator cover, and the natural principle of hot air evaporation is used to achieve the effect of vacuum preservation of food in the container, saving the cost of using a real packaging machine , can also achieve the effect of vacuum packaging and sealing.
