Abstract
The utility model discloses a kind of use of infusing without inner cap formula combination sealing cover, comprise composite cover body and sealing rubber pad, the inner chamber of described composite cover body middle part has a barrier layer, described barrier layer and composite cover body are integrated; The upper port edge of described composite cover body is formed with flanging through hot compression deformation, and described flanging is fixed on sealing rubber pad on barrier layer; Also comprise the composite aluminium film that is arranged on composite cover body upper port place.By the composite aluminium film easily tearing, the port of composite cover body is packed, during use, only need tear gently the composite aluminium film on composite cover body, the draw ring using is compared to existing technology convenient easy-to-use; Without installing inner cap additional, thereby avoid assembling product operation to bring secondary pollution to product, and overcome the past due to composite cover body and the combination of inner cap different materials, cause the unmanageable defect of welding temperature on transfusion flexible bag, plastic bottle and composite cover production line.
Description
Technical field
This utility model relates to the combination sealing cover of a kind of transfusion flexible bag, plastic bottle use, particularly relates to a kind of without inner cap formula combination sealing cover.
Background technology
Domestic and American-European countries is used for the most version adopting as shown in Figure 1 of combination sealing cover of transfusion flexible bag, plastic bottle at present, comprise composite cover body 10, inner cap 20, rubber sheet gasket 30 and composite cover draw ring 40, wherein inner cap 20 plays the effect that intercepts rubber sheet gasket 30 and medicament contact.There is following shortcoming in the combination sealing cover of this structure: inner cap 20 is not an injection molded with composite cover body 10, makes in process of production, adds easily generation secondary pollution when inner cap 20 is installed; Secondly, composite cover body 10 can directly affect the quality of infusion products with the tightness degree of inner cap 20 assemblings, thereby the assembling quality of need be rigid in checking up composite cover body 10 and inner cap 20, thereby causes the production low qualified of product.For addressing the above problem, China has done years of researches work in this respect, up to this point, does not achieve tangible results.
Utility model content
The deficiency existing for overcoming prior art, it is a kind of simple in structure, easy to operate, with low cost without inner cap formula combination sealing cover that the purpose of this utility model is to provide, and solves the secondary pollution producing in composite cover body and inner cap assembling process, the problem of quality control.
This utility model for solving the technical scheme of its technical problem employing is:
The use of infusing without an inner cap formula combination sealing cover, comprise composite cover body and sealing rubber pad, the inner chamber of described composite cover body middle part has a barrier layer, described barrier layer and composite cover body are integrated; The upper port edge of described composite cover body is formed with flanging through hot compression deformation, and described flanging is fixed on sealing rubber pad on barrier layer; Also comprise the composite aluminium film that is arranged on composite cover body upper port place.
Further, on described sealing rubber pad, be provided with vein puncture hole and liquid feeding puncturing hole.
Further, the bottom end face of described composite cover body is provided with for the hot weld junction with transfusion flexible bag, plastic bottle welding.
Further, described composite aluminium film is provided with the band ear of being convenient to be torn.
The beneficial effects of the utility model are: a kind of use of infusing that this utility model adopts without inner cap formula combination sealing cover, composite cover body has adopted all-in-one-piece obstruct mode, the barrier layer by integral type comes obstruction seals rubber blanket directly to contact with medicine; By the composite aluminium film easily tearing, the port of composite cover body is packed, during use, only need tear gently the composite aluminium film on composite cover body, the draw ring using is compared to existing technology convenient easy-to-use; Without installing inner cap additional, thereby avoid assembling product operation to bring secondary pollution to product, and overcome the past due to composite cover body and the combination of inner cap different materials, cause the unmanageable defect of welding temperature on transfusion flexible bag, plastic bottle and composite cover production line.This special design structure that this utility model adopts, relatively existing soft bag transfusion package product is more simple, material-saving, thereby has reduced cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Fig. 1 is the structural representation of combination sealing cover of the prior art;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the structural representation of sealing rubber pad of the present utility model;
Fig. 4 is the structural representation of composite aluminium film of the present utility model.
The specific embodiment
With reference to Fig. 2 to Fig. 4, a kind of use of infusing of the present utility model without inner cap formula combination sealing cover, comprise composite cover body 1 and sealing rubber pad 2, the inner chamber middle part of described composite cover body 1 has a barrier layer directly contacting with medicine for obstruction seals rubber blanket 24, and described barrier layer 4 is integrated with composite cover body 1.The upper port edge of described composite cover body 1 curves inwardly through hot compression deformation, thereby is formed with flanging 6, and described flanging 6 is fixed on sealing rubber pad 2 on barrier layer 4, and prevents that sealing rubber pad 2 is shifted, deviates from.Also comprise by hot pressing and be attached to the composite aluminium film 3 at composite cover body 1 upper port place, described composite aluminium film 3 is provided with the band ear 9 of being convenient to be torn, during use, only need tear gently the composite aluminium film 3 on composite cover body 1, the draw ring using is compared to existing technology convenient easy-to-use.
On described sealing rubber pad 2, be provided with vein puncture hole 7 and liquid feeding puncturing hole 8, during use, with transfusion instrument, carry out puncture and derive medicinal liquid, in the time of need adding medicinal liquid, also can carry out simultaneously.
The bottom end face of described composite cover body 1 is provided with for the hot weld junction 5 with transfusion flexible bag, plastic bottle welding.
The above, be preferred embodiment of the present utility model, and this utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
