Description

The deoxygenation Fresh keeping bottle cap

The utility model relates to a kind of bottle cap, and You Zhineng is used to remove the bottle cap of oxygen in the bottle.

At present, both at home and abroad the sealing of metal crown plug is adopted in the production of beverage such as beer, soy sauce, vinegar and seasonings mostly.But the oxidizing reaction that the oxygen in the bottleneck of sealing back causes will have a strong impact on the fresh-keeping and shelf-life of product.Especially for beer, influence more so.This has just influenced Beer Production greatly and has stored and sell.For solving the fresh-keeping problem of bottled beer deoxygenation, the patent No. is that 94242444.1 Chinese patent has provided a kind of beer deoxygenation leak free beer refreshing bottle cap that is used for, and is characterized in the finely porous barrier film of being with of on the seal ring of existing beer bottle cap heat seal one built-in deoxidizer.But also there is following weakness in it, the one, be with finely porous barrier film because its micro-porous adsorption and seepage effect and deposit, when realizing the micropore oxygen uptake, some component easy to leak in the deoxidizer is to beer, make the beer impurity content exceeding index, influence quality of beer, particularly free some content severe overweight that easily causes in the beer in the beer of some material in the deoxidizer, and can pollute seal ring, the out of reach state health standards.Next is a barrier film if adopt molecular film, and then its cost is too high, the requirement of out of reach economy, thereby limited its application in suitability for industrialized production.

The purpose of this utility model provides a kind ofly can effectively remove in the bottle oxygen and can not cause the deoxidizer seepage, deoxygenation Fresh keeping bottle cap with low cost.

The purpose of this utility model realizes by following technical solution:

Deoxygenation Fresh keeping bottle cap described in the utility model comprises the seal ring in lid and the lid, seal ring internal fixation one barrier film, and the built-in deoxidizer of barrier film is characterized in: a loop projection is arranged on the barrier film, and the inner chamber of this annular projection forms a circle ventilation ring; The inboard of the annular projection on this barrier film also has several strip projected parts, and the strip projected parts inner chamber forms air channel, and each air channel one end communicates with the inner chamber ventilation ring of annular projection, and the interior deoxidizer of the other end and barrier film communicates; Also be provided with the strip projected parts of some strip projected parts mutual dislocation inboard with it in the outside of the annular projection of this barrier film, the inner chamber of this each strip projected parts forms air channel, one end of each air channel communicates with the inner chamber ventilation ring of annular projection, and the other end and seal ring madial wall form admission port.

The utility model has the advantages that: when it is covered in bottleneck, be about to the bottle sealing, the admission port that air channel that the interior oxygen of bottle this moment will be formed by the outside strip projected parts of ventilation ring on the barrier film and seal ring madial wall form enters in the ventilation ring, the air channel that is formed by the inboard strip projected parts of ventilation ring enters into deoxidizer again, reacts with deoxidizer and is adsorbed and remove.And barrier film is not owing to be with micropore, and the deoxidizer in it can't dissociate and enter among the bottle, thereby can not produce any harmful effect to storage in the bottle.Structure owing to barrier film makes so again, the interior outside air channel mutual dislocation of its ventilation ring distributes, even bottle produces collision, rocks in carrying, inclination etc., the deoxidizer in the barrier film can not leak among the bottle by air channel yet, can not influence the quality of bottle contained object.On the contrary, because the adsorption of deoxidizer, the oxygen in the bottle will be removed.Generally can in 24 hours the oxygen concentration in the beer be reduced to below the 100ppb by the fresh concentration of 1300ppb, the level of oxygen in the bottleneck was reduced to below the 0.02mg by initial 1mg in 24 hours.Thereby the thing to bottle Nei Shengyi oxidation deterioration has played the good deoxygenation effect of guaranteeing the quality, and its shelf-life is prolonged greatly.Because structure of the present utility model makes so, barrier film can adopt cheap materials such as composite aluminium film, plastic film to make, thereby can reduce production costs greatly.

Below in conjunction with an embodiment technical solution of the present utility model is described in further detail:

Fig. 1 has provided agent structure of the present utility model and has cutd open scheme drawing;

Fig. 2 has provided the birds-eye view of Fig. 1.

In Fig. 1, the 1st, lid, the 2nd, the seal ring in the lid, the 5th, barrier film, this barrier film 5 can be used making such as aluminium film, plastic film, it and seal ring 2 pressing and fixing mutually, the 6th, deoxidizer can adopt pulvis or tablet.When adopting pulvis,, availablely be with finely porous packaging bag encapsulation to be placed in the barrier film for ease of suitability for industrialized production.One loop projection 4 is arranged on barrier film 5, and the inner chamber of this annular projection forms ventilation ring 41; Be provided with several strip projected parts 7 (referring to Fig. 2, providing 4 among the figure) in the inboard of this annular projection 4, its inner chamber forms air channel 71, and an end of each air channel communicates with ventilation ring 41, and the other end communicates with deoxidizer 6; Also be provided with several strip projected parts 8 (referring to Fig. 2, providing 4 among the figure) in the outside of this annular projection 4, its inner chamber forms air channel 81, and each air channel one end communicates with ventilation ring 41, and the madial wall of the other end and seal ring 2 forms admission port 3.In Fig. 2, the 1st, lid, the 2nd, the seal ring in the lid, the 3rd, admission port, the 4th, the annular projection on the barrier film, the 5th, barrier film, the 6th, deoxidizer, the 7th, the strip projected parts of annular projection 4 inboards, the 8th, the strip projected parts in annular projection 4 outsides, they the two between mutual dislocation distribute.Principle of work of the present utility model is as follows: it is packaged on the bottleneck, then the oxygen in the bottle will enter ventilation ring 41 in the annular projection 4 by air channel 81 by admission port 3, inner chamber air channel 71 by the strip projected parts 7 of annular projection 4 inboards enters in the deoxidizer again, is adsorbed with deoxidizer generation chemical reaction and removes.The formulation that how much reaches size, deoxidizer of air channel and consumption decision deoxygenation speed and effect.
