Detailed description of the invention

Attached drawing involved in the utility model embodiment description is simply introduced, in order to the utility model reality It applies the technical solution in example to be become apparent from, completely illustrated, some implementations of following attached drawing only for the utility model Example, is not intended to limit the utility model, under the premise of without other creative works, it is clear that can be according to these attached drawings Obtain other accompanying drawings.

Fig. 1 is a kind of longitudinal sectional view of combination sealing cover of the utility model.

Specific embodiment

The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical It is novel, it is not intended to limit the scope of the utility model.

As shown in Figure 1, the utility model provides a kind of combination sealing cover, including lower cover and upper cover 3, under wherein lower cover includes Lid ontology 1 and spout 2, the lower cover ontology 1 has lower base 1A, 1B suitable for reading and lower mouth 1C, wherein 1B suitable for reading is along lower base 1A Edge inner vertical set up, lower mouth 1C is down-set along the edge-perpendicular of lower base 1A.Lower base 1A is circular ring shape, institute 1B suitable for reading is stated as cylinder, lateral surface is equipped with the first annular screw thread 11 outwardly protruded, and lower mouth 1C is cylinder, medial surface Equipped with the second ring screw 12 outwardly protruded.

The hardness of lower cover material is greater than upper cover material, and the internal plug of such upper cover is filled in the 1B suitable for reading of lower cover, and the two is tight Cooperation can reach the purpose of sealing.

Preferably, material used by upper cover 3 is HDPE, and material used by lower cover is PP.

The spout 2 is off-centre operation cone shaped, and the upper end of the spout 2 is water outlet 21, and lower end is water inlet 22, water inlet The edge of mouth 22 connect to form cricoid platform 23 with the inside edge of lower base 1A, and the upper surface of platform 23 is inclined surface, and It is equipped with a return port 230 in the lower side of inclined surface, the top of the spout 2 is higher than the 1B suitable for reading.

Preferably, return port 230 is ellipse.

The inner wall of upper cover 3 is equipped with annular groove, and upper wall is equipped with annular internal plug 31, the annular groove and the first annular screw thread 11 cooperate, so that the upper cover 3 is fastened on 1B suitable for reading and covers the spout 2；It is described annular internal plug 31 length and Internal diameter limits in this way: when the upper cover 3 is screwed along the annular groove to lower end, the lower end of the annular internal plug 31 is put in It is abutted in the 1B suitable for reading and with the medial surface of the latter.

Preferably, the thickness of annular internal plug 31 gradually narrows from top to bottom, and the lower end in the outside of lower end is equipped with one tiltedly Face 310 facilitates the guidance of annular internal plug 31 into 1B suitable for reading.

When water is flowed out from spout 2, by the encirclement of annular internal plug 31 and upper cover 3, annular groove 31 is not flowed to, and from platform 23 return port 230 is back in bottle, to reach sealing purpose.

With continued reference to Fig. 1, further, the spout 2 has a first spout circumferential surface 2A and the second spout circumferential surface 2B, and described the Inclined angle alpha between one spout circumferential surface 2A and horizontal plane is less than the angle of inclination beta between the second spout circumferential surface 2B and horizontal plane.

The water outlet 21 of the spout 2 is arranged on the first spout circumferential surface 2A.

The platform 23 has inclined upper surface, and the upper surface of the platform 23 is close to the first spout circumferential surface The side of 2A is lower than it close to the side of the second spout circumferential surface 2B.As shown in Figure 1, the water of outflow can be along the upper end of platform 23 It flows from right to left in face.

Further, the platform 23 is arranged in close to one end of the first spout circumferential surface 2A in return port 230.Water can be flow to The return port 230 in left side returns in bottle body in turn.

Preferably, the lower end surface edge along the annular internal plug 31 is equipped with O-ring seals, increases annular internal plug 31 and lower cover Sealing effect between ontology 1.

Preferably, the material of O-ring seals is silica gel.

The above is only the preferred embodiments of the utility model, are not intended to limit the utility model, all in the utility model Spirit and principle within, any modification, equivalent replacement, improvement and so on should be included in the protection model of the utility model Within enclosing.
