Description

A kind of Easy tearing lid with degassing function

Technical field

This utility model is related to a kind of Easy tearing lid, more particularly to a kind of Easy tearing lid with degassing function.

Background technology

With the development of packaging container of metal industry technology, Easy tearing lid be widely used in milk powder, coffee powder, flavouring agent, Deng food packaging applications.Easy tearing lid is mainly aluminium foil and is coordinated with ring cover, through packaging processing, forms the good tank of a sealing Son, for sealing various articles up for safekeeping.

Aluminium foil is mainly sealed by the manufacturing process of the Easy tearing lid of prior art with ring cover, what a just does and complete easily tears Lid.The technology manufacturing procedure for preparing Easy tearing lid is simple, good airproof performance.

But just because of existing Easy tearing lid good airproof performance, when for packing beneficial microbe food, due to during storage Between it is long cause ferment and increase tank in air pressure, frequently can lead to after reaching certain pressure packing jar explosion, largely threaten The safety of consumer.Therefore, when the food of this class is packed, one is needed to maintain the packaging that pressure is consistent inside and outside tank easy Tear lid.

Utility model content

For above-mentioned deficiency, the purpose of this utility model is to provide a kind of Easy tearing lid with degassing function, makes interior external pressure Can be consistent by force, prevent explosion.

This utility model is to reach the technical scheme adopted by above-mentioned purpose to be：

A kind of Easy tearing lid with degassing function, including aluminium foil, is sheathed on the peripheral ring cover of aluminium foil, it is characterised in that described An opening is offered on aluminium foil, a filter disc is provided with the opening, and the edge of the filter disc is fitted with aluminium foil.

The opening of the aluminium foil is located at aluminium foil middle position；The filter disc fits in the upper surface or lower surface of aluminium foil； Generally circular in shape, generally circular in shape, and the diameter with diameter greater than opening of the filter disc of the filter disc of the opening.

The outward flange of the ring cover lower end is provided with an injecting glue groove；The outward flange of the ring cover is down bent to form a flange Structure, and the turnup structure is at the outer trough edge of injecting glue groove.Injecting glue groove can inject liquid sealant as needed, further carry The air-tightness of high ring cover.

Fitted by bonding mode between the filter disc and aluminium foil；By heat-sealing or glue between the ring cover and aluminium foil Glutinous bonding mode is engaged.

The filter disc is high ventilative filter disc, while the moisture in the external world, dust and debris effectively can be completely cut off, ensures food peace Entirely.

Further, as a diameter of more than 92.8mm of the Easy tearing lid, its size can accord with the demands of the market.

Further, as a diameter of 92.8～136.8mm of the Easy tearing lid, its size is suitable, goes for city Various common hermetically sealed cans on face.

The beneficial effects of the utility model are：

1) by increased high ventilative filter disc on Easy tearing lid, being consistent pressure inside and outside tank, preventing hermetically sealed can Explosion, it is ensured that food safety.

2) by increased high ventilative filter disc on Easy tearing lid, on the basis of ventilative, the external world still can effectively be completely cut off Moisture, dust and debris, ensure food safety.

Above-mentioned is the general introduction of utility model technical scheme, below in conjunction with accompanying drawing and specific embodiment, to this utility model It is described further.

Description of the drawings

Fig. 1 is schematic top plan view of the present utility model；

Fig. 2 is generalized section of the present utility model；

Fig. 3 is the enlarged diagram in I regions in Fig. 2；

In figure：Easy tearing lid 10；Aluminium foil 101；Ring cover 102；Filter disc 103；Flange 201；Injecting glue groove 202；Easy tearing lid section I areas Domain 30.

Specific embodiment

For further illustrating that this utility model is to reach technological means and effect that predetermined purpose is taken, below in conjunction with Accompanying drawing and preferred embodiment, describe in detail to specific embodiment of the present utility model.

Fig. 1 is refer to, this utility model embodiment provides a kind of Easy tearing lid with degassing function, and the Easy tearing lid 10 is by aluminium foil 101, filter disc 103, ring cover 102 are constituted；Ring cover is set in aluminium foil periphery, and the core of aluminium foil has a circular open, circular Circular filter disc 103 is provided with opening；Aluminium foil 101 is combined by the bonding mode sealing of heat-sealing or gluing with ring cover 102.

Fig. 1, Fig. 2 is refer to, the outward flange of 102 lower end of Easy tearing lid ring cover is provided with an injecting glue groove 202；The outward flange of ring cover A flange 201 is down bent to form, and the flange 201 is located at the outer trough edge of injecting glue groove 202.The effect of flange 201 is in order to anti- Only during can opening, the edge of packing jar is damaged to finger or body other parts.In order to reach airtight purpose, also Suitably injecting glue groove 202 can be filled with glue (such as rubber or resin), these glues stay in volume seam after crimping In, to increase sealed reliable degree.

Fig. 3 is refer to, the aluminium foil 101 of the core in Easy tearing lid section I regions 30 is with an opening, the following table at opening Face has filter disc 103.Filter disc 103 is bigger than aluminium foil 101, and, by bonding, compression combines for aluminium foil 101 and filter disc 103.Filter disc 103 Effect be the effectively extraneous moisture of isolation, dust and debris for compensator inner and outer air pressure, ensure food safety.

The above, is only preferred embodiment of the present utility model, and not technical scope of the present utility model is made Any restriction, therefore identical with this utility model above-described embodiment or approximate technical characteristic is adopted, in guarantor of the present utility model Within the scope of shield.
