Abstract
The utility model discloses a bottle cover which comprises a cover body and a tearable membrane, wherein a sealing pad is arranged in the middle of the outer end surface of the cover body; a puncture surface is arranged on the end surface of the sealing pad, facing to the inner side of the cover; a puncture positioning hole is formed in the end surface of the sealing pad, facing to the outer side of the cover; the tearable membrane is used for covering the outer end surface of the cover body. The bottle cover adopting the abovementioned structure has the following advantages: 1, the bottle cover is of an integral structure, the cover body can be used as both an inner cover and an outer cover, and the inner cover is not arranged, so that the cost is saved; 2, the bottle cover is simple in structure, simplified in production process, high in production efficiency and increased in production automation level; 3, the easily-tearable membrane structure is used, so that the problems of pull force and breakage of a pull ring are solved; 4, the sealing pad and the cover body are of the integral structure, so that the bottle cover is excellent in sealing property, better in needle holding effect and low in chip falling rate; 5, the bottle cover adopts a new production process and is formed in one step without semi-finished bottle cover storage, so that the pollution is alleviated and the convenience is provided for production management.
Description
Technical field
The utility model relates to transfusion medicine packing field, particularly a kind of bottle cap.
Background technology
Along with our economic development, people's medical level improves constantly, packing quality and technology are proposed to requirements at the higher level, China's novel infusion solutions packing technology is still in conceptual phase, have a lot of technical bottlenecks, need further to be improved, updating product engineering is the needs of industry development, the needs in client market, the key of enterprise core competitiveness especially.
Traditional group closing lid product in use at present, often there is the problem that pulling force is large, and the direction of pull difference of circular draw ring guide groove has a significant impact pulling force size, draw ring easy fracture simultaneously, therefore improved the quality of products and be very important by technological change.Leak tightness and the manufacturability of the mechanical array mode of existing combination cover are poor simultaneously, and production control difficulty is large, and production efficiency and yield rate are low, and degree of automation is difficult to improve.
Utility model content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of bottle cap, to reach without inner cap, cost-saving, the object of avoiding draw ring pulling force inequality and easy fracture problem to occur.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of bottle cap, comprise lid, the middle part of described lid outer face is provided with packing seal, described packing seal is provided with puncture face towards the end face in lid, the end face of described packing seal outside lid is provided with puncture knock hole, and described bottle cap also comprises the peelable diaphragm covering on lid outer face.
The periphery of described puncture face is connected on described lid, forms one.
Described diaphragm is welded on the annular protrusion stretching out on lid outer face.
Described diaphragm is provided with and tears handle.
The described handle that tears is two, is symmetrical arranged.
Described packing seal is thermoplastic elastomer packing seal, connects as one with lid.
The utility model adopts said structure, has the following advantages: 1, bottle cap is integral structure, and lid is that exterior and interior cover is dual-purpose, without inner cap, saves cost; 2, bottle cap is simple in structure, and production technology is simplified, and production efficiency is high, realizes the raising of production automation degree; 3, use the diaphragm structure easily tearing instead, solve draw ring pulling force and breakage problem; 4, packing seal and lid are integral structure, and leak tightness is good, embrace pin better effects if, and exfoliation is low.5, product adopts new production technology, and one-step shaping does not need half-blank to store, and reduces and pollutes, and is convenient to production control.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is birds-eye view of the present utility model;
In Fig. 1 ~ Fig. 2,1, lid; 2, diaphragm; 3, projection; 4, packing seal; 5, puncture knock hole; 6, puncture face; 21, tear handle.
The specific embodiment
A kind of bottle cap as shown in Fig. 1 ~ Fig. 2, comprises lid 1, and lid 1 adopts the medical material that can directly contact liquid, the middle part of lid 1 outer face is provided with packing seal 4, and packing seal 4 moulded manufacturabilities are good, without sulfuration, refining glue, can directly carry out injection moulding production, better tightness, puncture exfoliation is few.
Packing seal 4 is provided with very thin puncture face 6 towards the end face in lid, and puncture face 6 plays the effect of inner cap, directly contacts liquid.The end face of packing seal 4 outside lid is provided with puncture knock hole 5, and puncture knock hole 5 is two or three, for localised puncture position.Bottle cap also comprises the peelable diaphragm 2 covering on lid 1 outer face, for site of puncture, is not subject to outside contamination.
The periphery of puncture face 6 is connected on lid 1, forms one, and puncture face 6 adopts same material with lid 1.Diaphragm 2 is welded on the annular protrusion 3 stretching out on lid 1 outer face, and under high temperature, annular protrusion 3 is melt into plane after welding, makes welding more firm, seamless.Diaphragm 2 is provided with and tears handle 21.Tearing handle 21 is two, is symmetrical arranged.Product in use, as required, is torn half during dosing, during transfusion, tears second half again.Packing seal 4 is thermoplastic elastomer (TPE) packing seal, connects as one with lid 1.
Bottle cap, by injection machine one step processing, forms integral structure, and leak tightness is good, can not come off, and no longer needs a large amount of inner cap, enclosing cover half-blanks collected respectively, does not need group lid, and minimizing personnel, have improved production efficiency.
Injection moulding half-blank is sent into diaphragm welding post by oscillator, and the complete fusion weld of projection 3 on lid 1 top is connected into plane, diaphragm 2 and lid 1 close adhesion.Lid 1 is the material that directly contacts liquid, must select medical grade polypropylene (PP), or polypropylene (PP) and a small amount of elastomer blended material, through injecting machine material tube fusion plastification, be expelled to and in mold cavity, form lid 1, Rotate 180 ° arrives symmetrical station, now the TPE material of fusion plastification is expelled to lid and forms bottle cap half-blank, another station injection moulding simultaneously lid 1, PP and TPE bi-material carry out fusion plastification and injection process simultaneously, so circulation, produces continuously.
During injection moulding, enter glue point respectively in the centre of puncture face 6 upper surfaces and the upper surface centre of packing seal 4, mould is used the full hot runner system of needle valve, and product is without wire drawing, without gate materials.Packing seal 4 can also be made circle, ellipse, rounded square.Above-mentioned half-blank is sent in oscillator, and bottle cap enters the station of welding diaphragm 2 according to rule ordering, completes diaphragm 2 welding.During welding heating, projection 3 preheatings on lid 1 are wanted evenly, fully, to apply certain pressure during welding, make diaphragm 2 welding smooth seamless, will tear handle 21 and bend and be affixed on tegmental wall downwards.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted the technical solution of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
