Description

Ampoule opener

The utility model relates to a kind of device of opening leakproof tank, particularly the ampoule opener tool that is made of sleeve and cutting member (IPC B67B 7/92).

The ampoule opener tool that constitutes by sleeve and cutting member of the prior art, though advantage is respectively arranged, but there is following defective: the complex structure that has, by forming, as ampoule scarfing device (number of patent application 88220385.1), quick ampoule opener (number of patent application 89203637.0) etc. such as parts such as button pressing plate, retracing springs; The applicable surface that has is very little, can't satisfy the unlatching requirement of the ampoule of different bottlenecks, and ampoule Yin Gaowen seals and makes most of bottlenecks not of uniform size, then waste very greatly according to the different utensils of opening of different bottlenecks preparation, this defective is all arranged as inner-rotary type glass cutter (number of patent application 90203490.1), safety ampule cutter (number of patent application 88210894), ampoule opening device (number of patent application 91211316.2) etc.; The manufacture difficulty that has is big; The material requested expense that has, the cost height; What have is not difficult to the ampoule bottle neck break with bevelled ampoule bottleneck shape is consistent because of sleeve-shaped; The structure of a kind of ampoule opener (number of patent application 88209590.0) is relatively simple, but technology or more complicated with the fastener stationary cutter, sleeve cylindrical or elliptical cylinder-shape is difficult to bevelled ampoule bottleneck is fractureed after cutting smoothly, the sleeve that can't be out of shape is difficult to satisfy the particularly unlatching requirement of necking down ampoule of ampoule of different bottlenecks, does not make cutting very difficult because of the corresponding one side of cut point supports during cutting ampoule bottleneck.

Task of the present utility model is to overcome above-mentioned deficiency of the prior art exactly, and provide a kind of safety simple in structure, widely applicable, easy to use, material requested economize, easy to manufacture, cost is low and open effective ampoule opener tool.

The utility model proposes of task is finished by following design plan.The utility model is by having elasticity and constituting at finger soft sleeve that can be out of shape when pinching mutually and cutting member that can glass-cutting, and cutting member is fixed in sleeve and exposes to the inner wall surface of sleeve.Using method is: a hand-held ampoule to be opened, one hand-held the utility model, the finger of the hand of holding sleeve pinches on the sleeve position that is fixed with cutting member, after treating that the ampoule bottleneck puts in sleeve, finger firmly makes sleeve distortion, and the cutting member that exposes to the sleeve lining surface just touches the ampoule bottleneck, rotates the folding of making use of momentum behind ampoule or the turnbarrel certain angle then, the ampoule bottleneck is then fractureed, and whole unlatching work is finished.

The utility model compared with prior art has following advantage: the one, and simple in structure, easy to manufacture, entire product only is made of two parts, and its fixing means also is easier to; The 2nd, widely applicable, because sleeve can be out of shape,, adapt to the ampoule of different bottlenecks by the sleeve of making different size then applicable surface is much wide than of the prior art so cutting member can contact with the ampoule cutting part all the time.The 3rd, soft sleeve can be designed to the cone close with ampoule, and holds soft sleeve sleeve can be pasted mutually with ampoule bottleneck large tracts of land, thereby makes bottleneck more steady when cutting, and it is more convenient to fracture.The 4th, safer than prior art; because it is close-shaped and do not influence result of use that soft first sleeve can be designed to an end; and soft sleeve more can not make the ampoule fragmentation than hard sleeve; the 5th, material is economized, cost is low, only will have the plastic jacket for protection finger when hand is taken ampoule that disposes in the medicine box now and improve a little and load onto cutting member and get final product.

The utility model will be described further by accompanying drawing and embodiment.

Fig. 1 is a scheme drawing of the present utility model.

Fig. 2, Fig. 3, Fig. 4, Fig. 5 are embodiment scheme drawings of the present utility model.

As shown in the figure, (1) is sleeve, and (2) are cutting members, and (3) are the cutting supportings, and (4) are interior to the cutting supporting.Sleeve (1) can be made with any soft material, and as plastics, rubber or the like, its soft degree does not limit, as long as finger is pinched mutually and can be out of shape.The shape of sleeve (1) can be an Any shape, is generally taper shape (as Fig. 1), cylindrical (as Fig. 2), truncated cone-shaped (as Fig. 3), elliptical cylinder-shape etc., and preferred plan is according to the ampoule shaped design.One end of sleeve (1) must opening, so that ampoule puts in the sleeve, the other end can opening, also can seal, from the view of security with sealing for well.The barrel of sleeve (1) can be complete, also can be incomplete, considers to be designed to incomplete from saving in material, then is designed to complete from security consideration.The big I of sleeve (1) is according to the size design of ampoule, because of sleeve can be out of shape, when designing to be slightly larger than the ampoule bottleneck for well.The length of sleeve (1) is unqualified, guarantees that with saving in material safety is principle of design, also can be designed to cover ampoule part body (as Fig. 5), and is safer like this.Sleeve (1) can be designed to part bellows form (as Fig. 4), because its Telescopic can adapt to the unlatching requirement of the ampoule of different length.The material of cutting member (2) can be the material of any energy glass-cutting, from economic angle, is good with oxide based or carbonization system abrasive material.The size shape of cutting member (2) does not have fixed pattern, from the material-saving angle, is principle with little.The method that cutting member (2) is fixed on the sleeve (1) is unqualified, from economical, conveniently to consider with method of inlaying and viscose process be good, its method of inlaying can adopt the way solution that groove is inlayed in design on the barrel of sleeve (1), as long as corresponding cutting member is inlayed groove.The position that cutting member (2) is fixed on the sleeve (1) is unqualified, as long as can guarantee to make cutting member (2) can cut to relevant position.Cutting member (2) exposing on sleeve (1) inwall highly do not have specific requirement yet, for the necking down ampoule, then will satisfy the requirement of its neck degree of depth.Realize by turnbarrel (1) or rotation ampoule because cut the ampoule bottleneck, therefore can consider to be slightly thicker than the cutting supporting (3) of sleeve wall in the corresponding sleeve opposite side design one of cutting member (2), can the application of force when pinching mutually so that point.Then can design interior to cutting supporting (4) to guarantee that cutting member can rotate around bottleneck for the necking down ampoule.The shape size of cutting supporting (3) does not have fixed pattern, conveniently is principle to adapt to the finger application of force generally.In can design by different ampoules to the interior shape size and the height of cutting supporting (4) to the protruding point, do not do specific requirement, as long as in to can conflict bottleneck and play positioning action of cutting supporting (4).

Claims (1)

1, a kind of ampoule opener tool that is made of sleeve, cutting member is characterized in that, sleeve (1) is by having elasticity and making at the material that finger can be out of shape when pinching mutually, and cutting member (2) is fixed in sleeve (1) and exposes to the inner wall surface of sleeve (1).
