Description
Technical field
The invention belongs to medical packaging quality of materials detection field, more particularly to a kind of combination-type cover for plastic transfusion container
The method of its quick detection combination cover sealing of (enclosing cover) device for detecting sealability and application.
Background technology
With the progress and the development of medical level of science and technology, because glass bottle infuses frangible, and it must enter during infusion
Gas and cause the defects such as secondary pollution.Increasing polypropylene vial, polypropylene is collapsible butt-ended bag and the plastics bag such as non-PVC bags
The big infusion products of dress, because it is readily transported, without air inlet, the advantages of shrinking automatically is widely used in clinic.
Meanwhile, instead of the plug and aluminium lid of vial, polypropylene combination cover is synchronous with plastic infusion packing container and produces
It is raw.Polypropylene compositions are stamped inner cap, enclosing cover, the part of rubber cushion three and combined.Exterior and interior cover is molded by medical polypropylene and obtained.In order to
It is easy to clinical staff to operate.Usual enclosing cover is designed to the easy-opening enclosing covers such as frangible ring-pull type, easy fold-type.Therefore when enclosing cover is produced,
The easy place of opening is necessarily designed to the easy opening structure with cut channel, to meet the quality requirement of opening force.But high-capacity injection is produced
Product must be produced through high-temperature sterilization.So, the also easy stress that easily burst at the seams under high temperature action collapses out.And it is large quantities of to make lid production
Measure continuous production.So how to ensure outer combination cover quality in system lid production, it is necessary to a kind of not only quick but also accurately inspection
Enclosing cover sealing method is looked into, and injection parameterses are adjusted according to testing result in time.
In order to ensure the sealing of combination cover, at present, most of producers are equipped with quality testing department and the sealing of enclosing cover are entered
Row checks test.More conventional detection method is, the method detected using the permeability of methylene blue solution, its step
Including：(1) enclosing cover is taken, using wet method sterilization, at 121 DEG C, after sterilizing 30 minutes, lets cool to room temperature, forms testing sample；
(2) methylene blue solution is taken to prepare bleeding agent (65% ethanol：10g/L methylene blue solutions are 100:5)；(3) bleeding agent is filled out
It is charged to inside enclosing cover after 2/3 height, enclosing cover is positioned on filter paper and kept for 60 minutes；If at cut channel without leakage if detect close
Lattice, detect unqualified if having leakage at cut channel.
Although the method that the existing this permeability using methylene blue solution is detected also can be to the close of enclosing cover
Envelope property is detected, but this method but has following technical problem：
(1) this method is needed through high-temperature sterilization 30 minutes, then just carries out sealing propertytest after cooling, separately in detecting step
In need to be kept for 60 minutes, whole round of visits at least 150 minutes takes long, there is testing result delayed, it is impossible to meet big
The problem of batch quantity-produced needs；
(2) this method can only identify whether seepage and can not can be visually seen seepage place, it is impossible to quick Instructing manufacture adjustment
Operation；
(3) though this method is through high-temperature sterilization, and enclosing cover Impact direction is different when being sterilized from product, therefore sealing is still suffered from
The problem of property potential hidden danger of quality；
(4) test agent used in this method has blue characteristic, and the product after detection can not be recycled, if
The problem of recycling is likely to cause secondary pollution.
Face existing enclosing cover detection method and there are problems, research and development one kind at least can solve the problem that above mentioned problem
One of new method have become the new problem of this area.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art there is provided enclosing cover in a kind of combination-type cover for plastic transfusion container is close
The method of its detection enclosing cover sealing of envelope property detection means and application, to improve the detection efficiency and accuracy of enclosing cover, to be applicable
Needed in high-volume quantity-produced.
One aspect of the present invention there is provided enclosing cover device for detecting sealability in a kind of combination-type cover for plastic transfusion container,
The enclosing cover device for detecting sealability includes：Tank；Enclosing cover fixation kit, is arranged on inside tank, including：For supporting enclosing cover
Pedestal, pedestal is fixed on the bottom wall of tank, and internal provided with inflation duct, and inflation duct is from the bottom wall of pedestal to roof direction
Extension, and air-filled pore is formed with the roof of pedestal, outer cover gab is relative with air-filled pore to be arranged on pedestal；For fixing
The fixture of enclosing cover, fixture is connected with roof one end sealing of pedestal, and enclosing cover is fixed between pedestal and fixture；Test
Gas feeding mechanism, test gas feeding mechanism is connected with inflation duct.
In another aspect of the present invention, enclosing cover in a kind of above-mentioned combination-type cover for plastic transfusion container of application is additionally provided close
Envelope property detection means detects the detection method of enclosing cover sealing, and this comprises the following steps：Outer cover gab is relative with inflation duct
Be arranged on pedestal, and enclosing cover is fixed between pedestal and fixture with fixture；The water filling into tank, and make the water surface high
In enclosing cover top；Test gas feeding mechanism is opened, is inflated into inflation duct, whether the observation water surface has bubble generation, if nothing
Bubble, which produces to be considered as, detects qualified, detects unqualified if bubble produces to be considered as.
Using a kind of combination-type cover for plastic transfusion container (enclosing cover) device for detecting sealability of the invention and using its detection group
The method of closing lid sealing, enclosing cover is fixed using enclosing cover fixation kit, by the way that positioned at the inflation duct of base interior, outwards lid is applied
Plus external force so that cover the unreal or trickle slight crack of welding outside and be able to destroy or amplify, obtain potential sealing defect problem
With exposure.By setting tank, the characteristics of producing bubble in water using gas so that testing result is more directly perceived utilizes
Detect the observation of structure.Using this device for detecting sealability and the method for detecting enclosing cover sealing, it is not only able to improve detection
Accuracy, but also the detection efficiency of enclosing cover can be improved, it is applied to high-volume quantity-produced needs.
