Specific embodiment

Refering to attached drawing, a kind of thread lid 10 being used cooperatively with baby bottle (not shown) is shown.Thread lid 10 includes circle Opening at cylindrical side wall 12 and its lower end, this is contained in the neck of bottle in the opening of 12 lower end of side wall.Side wall 12 inner wall 14 includes screw thread 16, so that screw thread 16 is matched with the external screw thread being arranged in around neck part outer surface in known manner It closes.

Thread lid 10 further includes being laterally extended in the upper wall 18 of 12 upper end of side wall.Upper wall 18 includes opening 20.The opening 20 are arranged at 18 center of upper wall to accommodate nipple (not shown).

The upper surface of upper wall 18 has annular protrusion 22.Annular protrusion 22 is located at around opening 20 and its diameter is less than upper The diameter of wall 18, so that upper wall 18 includes the marginal portion 24 for being essentially perpendicular to the outer surface of adjacent side wall 12.Edge part Divide 24 can accommodate lid (not shown) in known manner.

Annular protrusion 22 in illustrated embodiment includes generally cylindrical outer wall section 26.Outer wall section 26 is from upper The cross-section cylindrical surface extended out and define the side wall 12 that one is substantially parallel to thread lid 10 in the marginal portion 24 of wall 18. Annular protrusion 22 further includes the inner wall section 28 of taper.Inner wall section 28 defines the surface of a conical butt, from outer wall The upper end of part 26 extends inwardly to the edge of opening 20.

Thread lid 10 can be sealed on opening 20 in no nipple equipped with seal disc 30.Seal disc 30 wraps Include a circular flat component, the circular protruding portion 32 that center has.Being dimensioned to of seal disc 30 can be contained in thread In the lower end of lid 10 and convex portion 32 be dimensioned to be contained in opening 20 in and be clamped in bottle and thread lid 10 Between in known manner will opening 20 sealing.

The inward flange of opening 20 is set as having multiple as shown in Figure 1 round the blocking protrusion 46(of open edge).This A little protrusions 46 are matched with the vertical edge of the convex portion 32 of seal disc 32.The vertical edge of convex portion 32 is slight Taper is so that the upper end of convex portion 32 is wider than bottom.Such setting enables seal disc 30 to be fixed in opening 20. The upper surface of seal disc 30 is also matched with a ring rib 48 to generate sealing effect, which is arranged around opening 20 in upper wall 18 Lower surface on (as shown in Figure 2 c).

The inner surface of the upper wall 18 of thread lid 10 has circular passage 34.Perimeter of the circular passage 34 in rib 48 Extend.The peripheral edge of the identical neck for making bottle in the top edge of neck of size and bottle of circular passage 34 and nipple cooperates, Peripheral edge to be pressed into channel 34 to make to be formed between nipple and bottle to seal.

Thread lid 10 is constructed by the material of relative stiffness, such as suitable rigid plastics.Thread lid 10 is configured in side wall The elastic layer 36 extended around 12 outer surface.Elastic layer 36 is formed by suitable elastic material, for example, thermoplastic elastomer (TPE) or Silica-base material, and by around the overmolded outer surface for being formed in side wall 12.

Elastic layer 36 extends around entire outer surface from the upper end to lower end in side wall 12.In the illustrated embodiment, Elastic layer 36 also extends over the marginal portion 24 of upper wall 18, as shown in Figure 2 c.

Elastic layer 36 also extends over the lower edge of side wall 12, as shown in Figure 2 c.The lower edge of side wall 12 is set as having The annular groove 38 adjacent with side wall inward flange.Elastic layer 36 in the embodiment shown also extends in annular groove 38.

The outer surface of elastic layer 36 is configurable to surface decoration 40, as shown in the figure.Surface decoration 40 can be with For promoting the aesthetic feeling of thread lid 10 and can be used for being easier to handle 10 outer surface of thread lid.The embodiment shown in In, a kind of wavy ridge is provided for holding and the notch 44 of aesthetic feeling and multiple diamond shapes is for holding.

It should be apparent to those skilled in the art that various changes and improvements can be made to foregoing embodiments (in addition to what is had been described) is without deviating from basic inventive concept of the invention.
