Abstract
The utility model relates to a complex membrane of rubber cork with an angled, circular, protruding tendon for seal and is primarily used for bottle caps of dropping bottles, comprising a tectum (1) and a cork neck (2) protruding onto the center of the tectum (1). A plurality of circular sealing protruding tendons (3) are arranged on the surface at the inferior end of the tectum (1), and one or more of the protruding tendons are designed in the shape of a cusp angle. The sealing protruding tendon is designed in the shape of a cusp angle in the current utility model, and when the protruding tendon is pressed, which is easy for the protruding tendon to change the shape and form a circular line seal. Corresponding tendons of cusp angles are designed at the fillet of the inner and outer walls at the bottle mouth so as to prevent the content from extravasation or exterior materials from contaminating the content, thus improving the leak tightness of the rubber cork. At the same time, the design of the cork into a conus can effectively prevent the skip of the cork while increasing the tightness of the cork.
Description
Technical field:
This utility model relates to a kind of plug, particularly relates to a kind of compound film rubber cork with tip-angled shape annular seal convex tendon.Main bottle cap as infusion bottle.Belong to medical technical field.
Background technology:
The compound film rubber cork that is used for infusion bottle has very at field of medicaments to be used widely.Compound film rubber cork in the past is made up of top cover and plug neck two parts.Transverse plane is provided with multiple tracks annular seal convex tendon under the top cover of its sealing that contacts with plane, infusion bottle bottleneck top.The compound film rubber cork of this kind structure, because its annular seal convex tendon is in the arc-shaped, during stressed compressing, the distortion of convex tendon is little, makes it can not fit tightly with bottleneck, so influences sealing property.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of compound film rubber cork that guarantees the band tip-angled shape annular seal convex tendon of sealing property is provided.
The purpose of this utility model is achieved in that a kind of compound film rubber cork with tip-angled shape annular seal convex tendon, being arranged at the intermediary plug neck of top cover by top cover and downward protrusion forms, transverse plane is provided with multiple tracks annular seal convex tendon under itself and the contacted top cover in plane, bottleneck top, it is characterized in that: the one or multi-channel tip-angled shape of being arranged in the described multiple tracks annular seal convex tendon.
The compound film rubber cork of this utility model band tip-angled shape annular seal convex tendon can also be designed to truncated cone with the plug neck.
This utility model is designed to tip-angled shape with seal bead on the common compound film rubber cork basis that has the annular seal convex tendon, the tip-angled shape convex tendon produces distortion when stressed, form cyclic linear sealing and with the bottleneck driving fit; And press close to two road tip-angled shape convex tendons of bottleneck inside and outside wall fillet punishment, can prevent that content from blending the pollution that external environment condition may cause content outward.To fill in neck simultaneously and be designed to truncated cone, when can effectively prevent to jump plug, improve its sealing property.
Description of drawings:
Fig. 1 is compound film rubber cork embodiment one structural representation of this utility model band tip-angled shape annular seal convex tendon.
Fig. 2 is compound film rubber cork embodiment two structural representations of this utility model band tip-angled shape annular seal convex tendon.
Fig. 3 is compound film rubber cork embodiment three structural representations of this utility model band tip-angled shape annular seal convex tendon.
The specific embodiment:
Referring to Fig. 1～3, the compound film rubber cork of this utility model band tip-angled shape annular seal convex tendon is made up of top cover 1 and the downward plug neck 2 that is arranged at the top cover center that protrudes.Transverse plane 1 is provided with multiple tracks annular seal convex tendon 3 under itself and the contacted top cover in plane, bottleneck top, and the set-up mode of described multiple tracks annular seal convex tendon 3 mainly contains following three kinds:
The structure of first kind of annular seal convex tendon as shown in Figure 1, the convex tendon 3.1 of inner ring is arranged to tip-angled shape in the multiple tracks annular seal convex tendon 3.
The structure of second kind of annular seal convex tendon as shown in Figure 2, the convex tendon 3.3 of inner ring and outmost turns is arranged to tip-angled shape in the multiple tracks annular seal convex tendon 3.
The structure of the third annular seal convex tendon as shown in Figure 3, each road convex tendon 3.1,3.2 and 3.3 of multiple tracks annular seal convex tendon 3 all is arranged to tip-angled shape.
The effect of inner ring convex tendon 3.1: can remedy internal diameter of the bottleneck upper end and the defective of facing the structure influence sealing effectiveness that is circular-arc directly, when the plug pressurized, the inner ring convex tendon is clamped on bottle mouth position, forms cyclic linear sealing, prevents that the bottle content from exosmosing.
The effect of outer ring convex tendon 3.2: there is the defective that influences sealing property in the radian design that can solve outer end, plane, bottleneck top, when the plug pressurized, the outer ring convex tendon produces distortion, forms cyclic linear sealing compressing in the bottleneck outer end, prevents that bottle external contamination source from entering in the bottle.
The effect of middle convex tendon 3.3: change semicircle convex tendon into tip-angled shape, when the plug pressurized, the wedge angle position is easy to generate deformation and forms cyclic linear sealing, more effective raising sealing property.
On the basis of above-mentioned change, this utility model can also be filled in neck 2 and be designed to truncated cone.
