Abstract
The utility model discloses a combination cover gasket for avoiding liquid leakage. The combination cover gasket comprises a base body, wherein an upper surface and a lower surface of the base body are respectively provided with a 1.5mm-2.5mm-deep liquid sealing groove which divides the base body into a gasket ring and a gasket body. The depth of the liquid sealing groove is 1.5mm-2.5mm, and therefore liquid sealing effect is improved, and the phenomenon of liquid leakage is prevented. By adding thickness of the gasket body, static retention force of a combination cover is improved, and a puncturing device is not prone to be pulled off when the puncturing device punctures through the gasket body. Meanwhile, the phenomenon of liquid leakage can be prevented. An upper surface and a lower surface of the gasket body are respectively provided with a puncturing hole for adding medicine and a puncturing hole for infusion so that contamination of liquid medicine caused by using the same hole for adding medicine and infusion can be avoided, and clinical operation is facilitated at the same time. The combination cover gasket is suitable for being popularized and applied to the liquid medicine packing field.
Description
Technical field
This utility model relates to the medicinal liquid packaging field, especially a kind of composite cover pad.
Background technology
In the medicinal liquid packaging process, consider infusion bottle particularity in use, for the bottle cap of infusion bottle special requirement is arranged; Generally; The general composite cover that adopts seals the bottleneck of infusion bottle, and enclosing cover and inner cap are stamped in combination, are provided with the pad that is used to seal between enclosing cover and the inner cap.At present, employed composite cover pad comprises matrix, and the upper surface of said matrix, lower surface are provided with the sealing liquid groove, and the sealing liquid groove is divided into gasket ring and pad with matrix, and the thickness of said pad is identical with the height of gasket ring, and the degree of depth of said sealing liquid groove is 1mm.In use there is following problem in this pad: at first, the degree of depth of existing sealing liquid groove is less, and the sealing liquid effect is relatively poor, and the phenomenon of leakage takes place easily; Secondly, because the height of gasket ring has restriction, thereby the mat body thickness of existing pad is less; And the static retentivity of composite cover is all provided by pad, and after this just made that perforator penetrates pad, the static retentivity of composite cover was less; Perforator is pulled off easily, simultaneously, and also leakage easily.
The utility model content
This utility model technical problem to be solved provides a kind of composite cover pad of avoiding taking place the phenomenon of leakage.
This utility model solves the technical scheme that its technical problem adopted: this composite cover pad; Comprise matrix; The upper surface of said matrix, lower surface are provided with the sealing liquid groove, and the sealing liquid groove is divided into gasket ring and pad with matrix, and the degree of depth of said sealing liquid groove is 1.5mm～2.5mm.
Further be that the thickness of said pad is greater than the height of gasket ring.
Further be that the thickness of said pad is greater than the height 0.5mm～1mm of gasket ring.
Further be that the upper surface of said pad, lower surface are provided with dosing puncturing hole, vein puncture hole.
The beneficial effect of this utility model is: through increasing the degree of depth of sealing liquid groove, can improve the sealing liquid effect, prevent the phenomenon of leakage.Through increasing the thickness of pad, can improve the static retentivity of composite cover, after perforator penetrated pad, perforator was not easy to be pulled off, and simultaneously, can prevent that also the phenomenon of leakage from taking place.The thickness of said pad can be under the prerequisite of the static retentivity that guarantees composite cover greater than the height 0.5mm～1mm of gasket ring, and economical with materials reduces cost to greatest extent.Upper surface, lower surface at pad all are provided with dosing puncturing hole, vein puncture hole, are to pollute medicinal liquid for fear of the shared hole of dosing and transfusion, simultaneously, also are convenient to clinical manipulation.
Description of drawings
Fig. 1 is the schematic cross-section of this utility model composite cover pad;
Fig. 2 is the vertical view of this utility model composite cover pad;
Description of symbols among the figure: matrix 1, gasket ring 11, pad 12, sealing liquid groove 2, dosing puncturing hole 3, vein puncture hole 4.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Like Fig. 1, shown in 2, this composite cover pad comprises matrix 1, and the upper surface of said matrix 1, lower surface are provided with sealing liquid groove 2, and sealing liquid groove 2 is divided into gasket ring 11 and pad 12 with matrix 1, and the degree of depth of said sealing liquid groove 2 is 1.5mm～2.5mm.The degree of depth of sealing liquid groove 2 is set to 1.5mm～2.5mm, and is bigger than the degree of depth of existing sealing liquid groove 2, can improve the sealing liquid effect, prevents the phenomenon of leakage.In order to increase the thickness of pad 12, improve the static retentivity of composite cover, the thickness of said pad 12 is greater than the height of gasket ring 11, and after perforator penetrated pad 12, perforator was not easy to be pulled off, and simultaneously, can prevent that also the phenomenon of leakage from taking place.The thickness of said pad 12 can freely be selected according to practical situation; Generally, generally be preferably: the thickness of said pad 12 can be under the prerequisite of the static retentivity that guarantees composite cover greater than the height 0.5mm～1mm of gasket ring 11; Economical with materials reduces cost to greatest extent.Upper surface, lower surface at pad 12 all are provided with dosing puncturing hole 3, vein puncture hole 4, are to pollute medicinal liquid for fear of the shared hole of dosing and transfusion, simultaneously, also are convenient to clinical manipulation.
