Abstract
The utility model discloses an oxygen absorbing fresh keeping sheet. The utility model is characterized in comprising an upper thin film, a lower thin film, and oxygen absorbing antistaling agent, wherein, the oxygen absorbing antistaling agent is sealed between the upper thin film and the lower thin film; the periphery of the upper thin film and the periphery of the lower thin film are connected with the installing edges of a container cover body; staggered vent holes are prearranged on the lower thin film, or circular rings of the vent holes for preventing liquid permeation are arranged on the upper thin film. The utility model has the advantage that the oxygen absorbing fresh keeping sheet can be easily arranged on the cover bodies of various sealing containers in a hot welding method or in a pasting method and has the advantages of improved practicability, improved production automated degree, good oxygen absorbing effect, and high safety. The utility model is suitable for removing oxygen for various kinds of wind, beverage, fruit juice, beer, fruit cans, etc. and keeping various kinds of wind, beverage, fruit juice, beer, fruit cans, etc. fresh.
Description
The utility model relates on a kind of lid that is installed in airtight container in order to absorb the oxygen uptake antistaling tablet of oxygen in the container.
As everyone knows, numerous food product, drinks, beverage, can, medicine etc. are oxidation deterioration easily, and storage life is shortened.In order to solve this difficult problem, the applicant just carried out the development of oxygen scavenger since 1964, present this oxygen scavenger has been widely used in food fresh keeping, as various aspects such as tealeaves, moon cake, peanut bean, jerky, dry fruit, dry vegetalbe, medicines, has obtained good effect.But this oxygen scavenger generally can only be used for the deoxygenation of solid matter fresh-keeping, just can't use for liquid beverage, fruit juice, fruit juice drinks, beer, fruit and vegetable can etc.For the deoxygenation that solves beer fresh-keeping, the applicant has successively proposed " fresh-keeping beer bottle cap " (patent No. is 90212182.0), " beer deoxygenation Fresh keeping bottle cap " (patent No. is 94242444.1), " the fresh-keeping anti-fake bottle lid of bottled beer deoxygenation degerming " series of patents applications such as (number of patent application are 97247344.0), these patents are remarkable for the oxidation deterioration effect fresh-keeping, that prevent beer that solves beer, the freshness date that has prolonged beer.But, in the above-mentioned patent application all with deoxidation antistaling agent attached on the bottle cap body, thereby the automated production equipment that makes the beer refreshing bottle cap has run into very big difficulty on design and manufacturing technology, the superfine powder of deoxidation antistaling agent is kicked up in high-speed production easily, and the die-cut of barrier film is difficult under the high-speed production condition realize with being welded on.And the lid of beer deoxygenation Fresh keeping bottle cap is a Crown shape bottle cap, can't be used for other beverage, as grape wine, rice wine, fruit and vegetable can.
The purpose of this utility model provides a kind of general, can be installed on the lid of various airtight containers in order to absorb the oxygen uptake antistaling tablet of oxygen in the container.
The purpose of this utility model is achieved in that a kind of oxygen uptake antistaling tablet, it is characterized in that it comprises upper film, following film and oxygen uptake antistaling agent, the oxygen uptake antistaling agent is sealed between upper film and the following film, extends the installation limit that is connected container top at the periphery of upper film and following film.In order to guarantee that oxygen in the container sees through film and enters in the oxygen uptake antistaling agent and absorbed, be provided with small passage on film or the upper film down.For the oxygen uptake antistaling tablet closely is bonded on the lid, make it to be recessed to form cavity downwards in the central authorities that descend film, the oxygen uptake antistaling agent places in this cavity, and upper film is flattened on down film cavity opening part.In addition, in order to prevent that the liquid in the container is penetrated in the oxygen uptake antistaling agent by the toe between oxygen uptake antistaling tablet and the lid and from passage, be provided with the passage of dislocation or be provided with the annulus that prevents the liquid infiltration on the surface of upper film at following film, this annulus can be one, also can be concentric several.After being installed to the oxygen uptake antistaling tablet on Crown shape bottle cap or other seal bottle cap, it is fresh-keeping to carry out deoxygenation to various beverages, fruit juice, beer, rice wine, grape wine, fruit and vegetable can etc., can in 1～2 day time, oxygen concentration be reduced to below 0.002, prevent oxidation deterioration effectively.
The utility model compared with prior art, its remarkable advantage is: 1, the oxygen uptake antistaling tablet can adopt the method for hot weld or stickup to be installed on the lid of various airtight containers, has improved the versatility of oxygen uptake antistaling tablet; 2, the oxygen uptake antistaling tablet is installed on the lid of container easily, for the automatic high speed production of the fresh-keeping lid of deoxygenation provides the condition that makes things convenient for; 3, the passage of oxygen uptake antistaling tablet is located at down on the film and adopts the dislocation micropore or be located on the upper film, has prevented that oxygen uptake antistaling agent component from leaking from passage, has also avoided liquid to be penetrated into from passage in the oxygen uptake antistaling agent simultaneously, and the oxygen uptake antistaling agent was lost efficacy; 4, the classification of the oxygen uptake antistaling agent in the oxygen uptake antistaling tablet and weight can adopt different components respectively according to the requirement of various products, adopt non-iron-based oxygen uptake antistaling agent as beer; 5, the oxygen uptake antistaling tablet is connected with lid with hot weld or binding agent, makes it into as a wholely, has overcome the defective that the beer refreshing bottle cap comes off individually fully, has improved security.6, owing to can realize automatization high speed production, product cost reduces, and is more convenient for applying.The utility model can extensively be used on the lid of various airtight containers, realizes that the deoxygenation of various products is fresh-keeping, and is fresh-keeping as the deoxygenation of beer, rice wine, grape wine, wine, juice-type beverage, fruit and vegetable can.
Below in conjunction with drawings and Examples the utility model is done further auspicious stating:
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation that the utility model has annulus
Fig. 3 is that the utility model is used for the structural representation on the beer Crown shape bottle cap.
Embodiment: to be used on the beer crown type bottle cap is example, and the oxygen uptake antistaling tablet that the utility model is made comprises upper film 1, following film 2 and oxygen uptake antistaling agent 3.Following film 2 is made by aluminium plastic membrane or paper film or other plastics, central authorities are prefabricated that recess arranged for it, a kind of oxygen uptake antistaling agent 3 efficient, quick, neutral, nontoxic, high-low temperature resistant is arranged on down in the recess of film 2 central authorities, and upper film 1 is sealed in down oxygen uptake antistaling agent 3 in the recess of film.The periphery of upper film 1 and following film 2 stretches out and forms an installation overlap 4 that is connected with bottle cap 7.Prefabricated or prick the passage 5 that has dislocation on following film 2, simultaneously, be provided with the annulus 6 that prevents the liquid infiltration on the surface of upper film 1.The oxygen uptake antistaling tablet combines with the gasket seal hot weld of bottle cap 7 by overlap 4 or is bonding with avirulent adhesion agent.The utility model is through repetition test, and effect is remarkable.
