Abstract
The utility model relates to an easy-to-pull transfusion bottle cap, which comprises a cap body with a skirt part. The upper part of the cap body is connected with a pull ring through a connecting column, the cap body is provided with an easy-to-pull welded ring, and the connecting column is fixedly connected with the easy-to-pull welded ring. When the bottle cap is opened, the force bearing area of the easy-to-pull welded ring is greatly reduced, the strength of tension on the easy-to-pull welded ring is greatly increased under the same tension, and thus the transfusion bottle cap is easier to be pulled open. The easy-to-pull transfusion bottle cap has a simple structure, is easy to process, is convenient to use, can be directly formed in one step on an injection molding machine, and can be well welded with a bottle body. Moreover, the easy-to-pull transfusion bottle cap can be used with a rubber plug and has good sealing performance.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments additional device, a kind of specifically easy-to-pull infusion bottle bottle cap.
Background technology
We know that the infusion bottle enclosing cover generally is to be made by aluminum alloy sheet in the past, because metal scratches finger easily, also are easy to damage and pollute the rubber stopper of internal layer, use inconvenience, are therefore replaced by vinyl cover gradually.Existing macromolecular material infusion bottle is mainly made by the polypropylene material, and the infusion bottle bottle cap generally is that polyethylene material is made, and it is connected with the infusion bottle bottle with welding manner by screw thread.On the one hand because bottle and bottle cap material different, connect, sealing property is bad, equipped connect unreliable; Use on the other hand and open also inconvenience.Make vinyl cover be difficult to draw back even produce the situation that draw ring is torn.For example crown cap adopts oval indentation among the ZL94241212.5, and vinyl cover adopts circular weld mark among ZL98204477.1 and the ZL200420052144.3, and there is the problem that is difficult to draw back in actual applications in the latter.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple and reasonable for structure, and handling ease can directly once molding on injection machine, assembling and easy-to-pull Infusion bottle lid easy to use.
The technical scheme in the invention for solving the above technical problem is: a kind of easy-to-pull Infusion bottle lid, it is provided with a lid that has a skirt section, lid top connects a draw ring by a joint pin, it is characterized in that: lid is provided with easy-to-draw welded ring, and joint pin and easy-to-draw welded ring are connected and fixed.
The said easy-to-draw welded ring of this utility model surface in lid is respectively equipped with weld mark outside the annular of weld mark and sealing in semi-enclosed annular.
The degree of depth of weld mark is less than the thickness of lid in outer weld mark of this utility model ring-type and the annular.
This utility model lid is provided with the easy-to-draw welded ring that connects draw ring, be provided with the outer weld mark of annular of interior weld mark of semi-enclosed annular and sealing inside and outside the easy-to-draw welded ring, the contrast prior art, this utility model has increased weld mark in semi-enclosed annular, in the process that bottle cap draws back, the lifting surface area of easy-to-draw welded ring significantly reduces, under identical pulling force, the tension intensity that produces on the easy-to-draw welded ring has improved greatly, thus easier being drawn back.Its simple in structure, handling ease, easy to use, can directly once molding on injection machine, good with the bottle weldability, can with the supporting use of rubber stopper, good airproof performance.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described further.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to sketch map.
1. lids among the figure, 2. easy-to-draw welded ring, 3. draw ring, 4. joint pin, 5. outer weld mark, 6. in weld mark.
The specific embodiment
Below in conjunction with embodiment this utility model is further described.
From Fig. 1 and Fig. 2 as can be seen, a kind of easy-to-pull Infusion bottle lid of this utility model, it is provided with a lid 1 that has a skirt section, and lid 1 top connects a draw ring 3 by a joint pin 4.The skirt section of bottle cap 1 is one the structure of stepped ramp type to be arranged, and the first half diameter is less, is used with rubber stopper; The latter half diameter is bigger, cooperates with bottleneck.During installation, the aligning bottleneck firmly presses down bottle cap 1, adds through high temperature to be thermally welded on the bottle again, and is good with the weldability of bottle.Draw ring 3 does not ftracture through behind the high temperature sterilize, easily draws back.
This utility model lid 1 is provided with easy-to-draw welded ring 2, and joint pin 4 lower ends and easy-to-draw welded ring 2 are connected and fixed.The said easy-to-draw welded ring 2 of this utility model is weld mark 5 outside 1 li surface of lid is respectively equipped with the annular of weld mark in semi-enclosed annular 6 and sealing.As shown in Figure 2.
The degree of depth of outer weld mark 5 of this utility model and interior weld mark 6 is less than the thickness of lid 1.Like this, the easy-to-draw welded ring 2 of this utility model forms the inner and outer boundary line by weld mark 6 in the outer weld mark 5 of annular that seals and the semi-enclosed annular, and the inboard is connected with nucleome in the lid 1 by connecting portion.During use,, exert oneself gently, easy-to-draw welded ring 2 can be opened together with nucleome in the lid 1 weld mark 5 and interior weld mark 6 outside annular as long as catch on draw ring 3 with finger, the rubber stopper inside exposing, contact pin can use.In the process that bottle cap draws back, the lifting surface area of easy-to-draw welded ring 2 significantly reduces, and under identical pulling force, the tension intensity that produces on the easy-to-draw welded ring has improved greatly, thus easier being drawn back.Its simple in structure, handling ease, easy to use, can directly once molding on injection machine, good with the bottle weldability, can with the supporting use of rubber stopper, good airproof performance.
