Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A double-color injection-molded infusion combined cover is shown in figures 1-3 and comprises an outer cover 1, a rubber plug 2 and a film 3, wherein the outer cover 1 is cylindrical, the upper end of the outer cover is upwards and convexly provided with a rubber plug chamber 4, the middle of the rubber plug chamber 4 is provided with a partition 41 for dividing the rubber plug chamber 4 into a left cavity and a right cavity, and the partition 41 is concavely provided with a groove 42 for connecting the left cavity and the right cavity; the rubber plug 2 is arranged in the rubber plug chamber 4, and the pad pasting 3 is attached to the upper opening of the rubber plug chamber 4, so that the rubber plug chamber 4 forms a closed space, and the inside of the combined cover is prevented from being polluted when the combined cover is not used. The lower end surface of the outer cover 1 is radially and outwardly extended with a connecting part 5 connected with the infusion bag.

In one embodiment, as shown in fig. 1 to 3, the outer wall of the rubber plug chamber 4 is symmetrically provided with attaching portions 43, which are vertical edges.

In the above embodiment, as shown in fig. 1 to 3, the fixing portions 31 engaged with the attaching portions 43 are provided on both sides of the adhesive film 3. The fixing portion and the attaching portion 43 are engaged with each other, so that the attaching strength of the adhesive film 3 is improved. Preferably, the fixing portion 31 is provided with a hand tearing portion 32 extending outwardly. That is, an unattached portion is reserved at one end of the fixing portion 31 to facilitate the operator to tear the attachment film 3.
