Description
Technical field
This utility model relates to teared cap, particularly a kind of teared cap without inner cap.
Background technology
At present, the conventional combination lid product that domestic market uses, comprises enclosing cover, rubber stopper and inner cap.Rubber stopper is arranged between enclosing cover and inner cap.When assembling, rubber stopper is placed on the inside of enclosing cover, then puts into inner cap, inner cap is fixed together by the buckle structure between inner cap external annulus and enclosing cover internal ring wall and outer cover latch, thus is fixed in enclosing cover by rubber stopper buckle.Owing to not having buckle structure between inner cap and enclosing cover, in order to rubber stopper can be fastened reliably, strict buckle is needed to be fixed on the size of cooperate degree between enclosing cover and buckle structure, therefore higher to the requirement on machining accuracy of inner cap; Inner cap in use will contact with medicinal liquid simultaneously, must ensure to make medicinal liquid go bad, to the plastics that inner cap uses, this requires that quality is higher; In prior art, the inner cap of composite cover adopts PE plastics or PP plastics usually in addition, and PE plastics or the soft and non-refractory of the quality of PP plastics own, may occur distortion, also easily cause inner cap and enclosing cover to get loose, and then cause rubber stopper to get loose after high temperature sterilize; Visible, the inner cap in existing composite cover should be noted that a problem such as precision and material selection of getting home, and the difficult quality of inner cap controls, and brings very large difficulty to the high-quality product of production.
At present, for the problem that the difficult quality solving inner cap controls, market there is the composite cover without inner cap, as Chinese patent, infusion vessel and composite cover thereof (application number for: 2009202231819): composite cover comprises enclosing cover and rubber cushion, wherein, described composite cover also comprises buckle structure, described rubber cushion is fixed on enclosing cover inside by buckle structure, its buckle structure is buckle flange collar, described buckle flange collar is along the circumferential direction arranged on the internal ring wall of enclosing cover, the lower surface of described rubber cushion is buckled in described buckle flange collar, enclosing cover and bottle are welded together by sealed plastic film phonograph seal, but this kind of mode, after welding, cannot ensure that weld has seamless, if there is crack, bottle built with medicinal liquid bottle stand upside down or when keeping flat, medicinal liquid can flow out along crack, cause the waste of medicinal liquid, and when enclosing cover and bottle snapping, positioning convex portion is easily caused to be out of shape, the locating effect of enclosing cover is reduced, thus increase the welding difficulty of enclosing cover.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides that a kind of structure is simple, rubber stopper stationarity is good and the teared cap without inner cap of good airproof performance.
The purpose of this utility model is achieved through the following technical solutions: a kind of teared cap without inner cap, it comprises enclosing cover, rubber stopper and rubber stopper fixed structure, rubber stopper is arranged in enclosing cover, described rubber stopper fixed structure is made up of cannelure and arc flange collar, described cannelure is opened on the medial wall that enclosing cover contacts with rubber stopper, arc flange collar is arranged on the bottom that enclosing cover medial wall contacts with rubber stopper, described enclosing cover medial wall is also provided with a ring-shaped step, described ring-shaped step is positioned at below rubber stopper, ring-shaped step is triangle, its upper end is plane, the upper transverse plane of ring-shaped step is pasted with a rubber cushion, described cover bottom portion radial direction extends to form the flange connector connecting bottle.
Described arc flange collar is made up of upper arc-shaped edges and lower arc-shaped edges, wherein goes up arc-shaped edges and fixes rubber stopper, and lower arc-shaped edges is in order to support rubber plug.
Described enclosing cover upper end is provided with a tearing port, and tearing port forms by tearing handle and tearing base, wherein tears base and is connected with enclosing cover upper end.
This utility model has the following advantages: rubber stopper of the present utility model by cannelure and arcuate groove dual fixing, rubber stopper is fixed in enclosing cover, thus adds the stationarity of rubber stopper; The ring-shaped step arranged, ring-shaped step medial wall is inclined-plane, reduces the snapping difficulty of enclosing cover, the breakage caused when simultaneously it also avoid ring-shaped step and bottle step snapping, and the steadiness of enclosing cover is strengthened; Ring-shaped step is provided with rubber cushion, makes enclosing cover and the many one deck sealing rings of bottleneck, when rubber cushion does not damage, even if having gap during enclosing cover welding, medicinal liquid in bottle also can not seepage, thus adds the sealing of teared cap, thus avoids the waste that Drug leakage causes.
