Abstract
A novel combined cap of a large infusion bottle relates to a bottle cap of a medical infusion bottle, which can simplify the technique flow, saves energy consumption, increases production efficiency, reduces production cost, and can reduce fallen scraps, and has excellent safety. The bottle cap comprises an outer cap and an inner cap which are mutually buckled, wherein the top center of the outer cover is a tearing film with a pull ring, the top surface of the inner cap is a film layer. The novel combined cap is characterized in that a thermoplastic elastic sealing pad is arranged between the outer cap and the inner cap, and a cone pinprick is arranged on the thermoplastic elastic sealing pad. The production technique is simple, and a needle can enter into liquid in a large infusion bottle after being inserted in the cone pinprick on the thermoplastic elastic sealing pad to pass through the film layer on the top of the inner cap when in use, as the bottom of the pinprick is in a conical tip shape, and a sharp opening in a horseshoe shape slides into a jack along the cone face of the pinprick to reduce the generation of fallen scraps when the oblique needle point of the needle is inserted, and the thermoplastic elastic sealing pad has reasonable and scientific structure, and the safety of the product is increased.
Description
Technical field:
This utility model relates to a kind of bottle cap of medical infusion bottle.A kind of novel composite cover of large transfusion bottle particularly.
Background technology:
Present medical large transfusion bottle adopts glass or macromolecular material to make mostly, and wherein, the large transfusion bottle so that macromolecular material is made because of it possesses the fragility of being difficult for, is widely used.For the large transfusion bottle that macromolecular material is made, polygamy is equipped with combined bottle cap at present; This combined bottle cap is fastened by enclosing cover and inner cap and forms; The caping of enclosing cover is provided with the easily tore film that has draw ring; The caping of inner cap is a thin layer; Filling isoprene rubber gasket seal between enclosing cover and inner cap; On the isoprene rubber gasket seal, be provided with the truncated cone-shaped pinprick, as Fig. 5, shown in 6.
During production, behind filling liquid in the large transfusion bottle, the bottleneck heat seal sealing of the large transfusion bottle that combined bottle cap and macromolecular material are made; During use, draw ring on the pulling enclosing cover caping, its easily tore film can be torn, form opening, expose the isoprene rubber gasket seal, syringe needle is inserted truncated cone-shaped pinprick on the isoprene rubber gasket seal, syringe needle passes the thin layer of truncated cone-shaped pinprick and inner cap caping, can inject in the large transfusion bottle, be used for infusion treatment.This combined bottle cap has improved the sealing of large transfusion bottle, and operation is fairly simple during use.
But, this traditional large transfusion bottle combined bottle cap is owing to adopt the isoprene rubber gasket seal, its complex manufacturing technology needs through following flow process: raw material incoming inspection-batching-mixing-refine-sulfuration-finished product trimming pruning-cleaning-operations such as physicochemical property detection-packing.Because this complex manufacturing technology, therefore, its energy consumption is big, and defect ware rate height causes production efficiency low, the production cost height.
And, because the pinprick of the isoprene rubber gasket seal of this traditional large transfusion bottle combined bottle cap is a truncated cone-shaped, and the angle needle point of syringe needle is the wedge surface that has the syringe needle hole, the syringe needle hole forms horseshoe-shaped sharp mouthful on wedge surface, when the angle needle point passes the truncated cone-shaped pinprick of isoprene rubber gasket seal, horseshoe-shaped sharp mouth may make the truncated cone-shaped pinprick form exfoliation, and exfoliation may stop up syringe needle or bring in the liquid, the influence treatment.
Summary of the invention:
This utility model aims to provide a kind of novel composite cover of large transfusion bottle.It can simplify technological process, and energy efficient is enhanced productivity, and reduces production costs, and can reduce the acupuncture exfoliation, and safety is good.
The technical solution of the utility model:
This utility model comprises the enclosing cover and the inner cap of mutual fastening; The caping center of enclosing cover is the easily tore film that has draw ring; The caping of inner cap is a thin layer; Between enclosing cover and inner cap, be provided with the thermoplastic elastomer (TPE) gasket seal; On the thermoplastic elastomer (TPE) gasket seal, be provided with the taper pinprick, as Fig. 1,2,3, shown in 4.
Pinprick of the present utility model can be one, also can be a plurality of.
Thermoplastic elastomer (TPE) gasket seal of the present utility model can be a SEBS-hydrogenated butadiene styrol copolymer gasket seal, TPE-polyolefin elastomer gasket seal, TPV-dynamic vulcanization EP rubbers and polypropylene copolymer gasket seal etc.
Operation principles of the present utility model and good effect
The technological process of production of thermoplastic elastomer (TPE) gasket seal of the present utility model is:
Raw material incoming inspection-injection mo(u)lding-cleaning-operations such as physicochemical property detection-packing is compared with the production procedure of traditional isoprene rubber gasket seal, because technology is simple, has correspondingly saved energy consumption, has enhanced productivity, and reduces production costs.
After testing, correlated performance such as following table are listed;
| Material | Absorbance | PH value | Permanganate number ml | Ash % |
| The YBB00232004 national standard | ≤0.3 | ≤1 | ≤3 | ≤25 |
| The thermoplastic elastomer (TPE) gasket seal | 0.030 | 0.01 | 0.5 | 0.1 |
Testing result shows that the performance of thermoplastic elastomer (TPE) gasket seal meets the examination criteria of State Food and Drug Administration about national drug packing container (material), and promptly standard No. is the national standard of YBB00232004.
Behind filling liquid in the large transfusion bottle, the bottleneck heat seal sealing of the large transfusion bottle that this utility model and macromolecular material are made.During use, utilize draw ring that the easily tore film at the caping center of enclosing cover is drawn back, syringe needle is inserted the taper pinprick that the thermoplastic elastomer (TPE) gasket seal is provided with after, the thin layer of the caping by inner cap, enter in the liquid in the large transfusion bottle, just can carry out infusion treatment; Because the bottom of taper pinprick is a cone tip shape, therefore, when the angle needle point of syringe needle inserts, the horseshoe-shaped sharp mouthful of taper surface along pinprick slips into socket, reduced the generation of exfoliation, the thermoplastic elastomer (TPE) gasket seal is scientific and reasonable for structure, has improved security of products.
In sum, this utility model is a kind of novel composite cover of large transfusion bottle.It can simplify technological process, and energy efficient is enhanced productivity, and reduces production costs, and can reduce the acupuncture exfoliation, and safety is good.
