Description
Technical field
This utility model belongs to the drug packaging product technical field, relates to the improvement of injection with the flap Intermediate gasket of bottle (or liquid bag), is a kind of dish-shaped flange gasket specifically.
Background technology
Existing injection is made up of cabinet, inner shell and rubber sheet gasket wherein with the plastics flap of bottle (or liquid bag), be provided with the pad container cavity on cabinet, the inner shell, existing rubber sheet gasket global shape is isometrical cylindrical, and the pad end face is provided with the elasticity bulge loop.During use, rubber sheet gasket is pressed in the pad container cavity of cabinet and inner shell, inner shell is sealedly attached on medicine bottle (or the liquid bag) bottleneck, plays sealing function.The rubber sheet gasket thickness that has is mild decline trend by around the elasticity bulge loop to central authorities, and the thinnest part of pad is located at the center of circle of elasticity bulge loop.There is following shortcoming in existing pad: the one, and pad cooperates existing problems with the size of plastics flap, and because of the restriction of production technology, there is error in the size between plastics flap and the pad.If during greater than the pad container cavity internal diameter in the plastics flap, there is the assembling situation of difficult in the diameter of pad; If during less than the pad container cavity internal diameter in the plastics flap, there is the problem of leakage in the diameter of pad behind the contact pin.The 2nd, the thinnest part of pad is located at the center of circle of elastic flange, and slotting hour hands are difficult for finding accurately the centre point of elastic flange, and promptly the contact pin position is difficult for dropping on the thinnest part of pad, if the acupuncture treatment position is thicker, can make the bad from close property of pin hole.
How to design a kind of rubber sheet gasket, it is rational in infrastructure, and is easy for installation, and sealing is reliable, and contact pin is easy to operate, avoids the phenomenon of acupuncture exfoliation.This is the technical problem that present present technique field needs to be resolved hurrily.
Summary of the invention
This utility model provides a kind of dish-shaped flange gasket at the problems referred to above that prior art exists, and it is rational in infrastructure, and is easy for installation, and sealing is reliable; Contact pin is easy to operate, and pin hole is good from close property.
The purpose of this utility model is achieved through the following technical solutions:
A kind of dish-shaped flange gasket, described clout body are circular, and the pad end face is provided with the elasticity bulge loop, and the side that it is characterized in that described pad is the arcwall face of middle part evagination, and the diameter of pad end face and bottom surface is less than the diameter at the middle part of pad.
Operate for ease of contact pin, to improvement of the technical scheme: the middle part is an inner concave around the elasticity bulge loop on the described pad end face, described inner concave centre forms a circular platform, described circular platform thickness uniformity, and be the thinnest position of pad.
To further improvement in the technical proposal: the bottom shape of described pad is identical with the pad end face.
To further improvement in the technical proposal: described pad is left-right symmetric and laterally zygomorphic shape along the section of axis.
To further improvement in the technical proposal: the diameter of circular platform is at least 3mm on the described pad, and the thickness at described pad circular platform position is less than 3mm.
To further improvement in the technical proposal: the diameter of described pad end face and bottom surface is identical, and the diameter at described pad middle part is than pad end face diameter or the big at least 0.4mm of bottom surface diameter.
To further improvement in the technical proposal: described pad is the integrative-structure that rubber or plastic cement are made.
This utility model compared with prior art has following advantage and good effect:
1, this utility model dish flange gasket is convenient to assembling.Therefore the diameter of pad end face and bottom surface, can play the effect of guiding less than the internal diameter of cabinet and inner shell pad container cavity when assembling, make pad can enter cabinet and inner shell pad container cavity inside very easily.
2, this utility model dish flange gasket favorable sealing property.The diameter at pad middle part is equal to or slightly greater than the internal diameter of cabinet and inner shell pad container cavity, and therefore, after assembling was finished, the interior wall energy of the middle part of pad and working of plastics formed good band, has avoided leakage.
3, the middle part is an inner concave around the elasticity bulge loop on this utility model dish flange gasket end face, and described inner concave centre forms a circular platform, and the thickness uniformity, is the thinnest position of pad.The circular platform area is bigger, and thickness is the thinnest, is convenient to contact pin operation, improves the contact pin position and is in the accuracy at thin position of pad, avoids the contact pin position to be forbidden to cause the phenomenon of acupuncture exfoliation, after pin is extracted, and pin hole good from close property.

Fig. 2 is the vertical view of this utility model dish flange gasket.
Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
The specific embodiment
A kind of dish-shaped flange gasket of this utility model, described clout body are circular, and the pad end face is provided with the elasticity bulge loop, and the side that it is characterized in that described pad is the arcwall face of middle part evagination, and the diameter of pad end face and bottom surface is less than the diameter at the middle part of pad.
Referring to Fig. 1-Fig. 3, the embodiment of a kind of dish-shaped flange gasket of this utility model, concrete structure: described clout body 3 is circular, and pad 3 end faces and bottom surface are equipped with elasticity bulge loop 4, elasticity bulge loop 4 is outer be a circle flat edge along 1, the side 2 of described pad 3 is the arcwall face of middle part evagination.The diameter of described pad 3 end faces and bottom surface is identical, and the diameter at described pad 3 middle parts is than pad 3 end face diameters or the big at least 0.4mm of bottom surface diameter.
The middle part is an inner concave around the elasticity bulge loop 4 on above-mentioned pad 3 end faces, and described inner concave centre forms a circular platform 5, described circular platform 5 thickness uniformities, and be the thinnest position of pad, described pad 3 end faces are dish.
The diameter of circular platform 5 is at least 3mm on the above-mentioned pad 3, and circular platform 5 areas are bigger, is convenient to the contact pin operation.The thickness at circular platform 5 positions avoids the contact pin position to be forbidden to cause the phenomenon of acupuncture exfoliation less than 3mm.
The bottom shape of above-mentioned pad 3 is identical with pad 3 end faces.Pad 3 is left-right symmetric and laterally zygomorphic shape along the section of axis.
Above-mentioned pad 3 is the integrative-structure that rubber or plastic cement are made, and elasticity bulge loop 4 diameters are 8-10mm, and the average diameter of described pad 3 is 10-12mm, and the average thickness of pad 3 is 4-6mm.
This utility model dish dome pad is mainly used in the two easy-to-pull flaps of injection bag, during use, pad 3 is pressed in cabinet and the inner shell pad container cavity, because pad 3 end faces and bottom surface diameter are less than cabinet and inner shell pad container cavity internal diameter, therefore, when assembling, can play the effect of guiding, make pad 3 can enter the inside of cabinet and inner shell pad container cavity very easily.The diameter of pad 3 sides 2 middle part evaginations is equal to or slightly greater than the pad container cavity internal diameter of cabinet, and therefore, after assembling was finished, the interior wall energy of the middle part of pad 3 and cabinet pad container cavity formed good band, can avoid leakage.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and this utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of having done, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
