CN2179083Y - Full-function durable thermal insulation cork - Google Patents

Abstract

The utility model provides a full function durable thermal insulation cork, which comprises a cork housing matched with a container mouth, an outer cover which is matched with the cork housing and is connected by a hinge shaft, a hollow inner cork fixed in the outer cover, and a movable cork arranged in an inner cork. The container cover does not need to be taken off because the outer cover and the inner cover can be automatically opened when the container is inclined, and when the container is vertical, the outer cover and the inner cover can be automatically closed. The utility model is suitable for matching with thermos flasks and other containers with various specifications, and has the advantages of simple structure, sanitation, cleanness, good thermal insulation performance, convenient operation and high durability.

Description

Full-function durable thermal insulation cork

The utility model relates to a kind of daily living article, particularly relates to a kind of durable global function insulation plug.

Vacuum flask generally all uses cork to make interior plug, and some then at the interior enclosing cover that covers again beyond the Great Wall, takes off with hand during use, and is not only unhygienic but also inconvenient.Chinese patent notification number 20580850 discloses a kind of automatic and has closed thermos cork, and the first half has an automatic valve device, and there is a delivery port side, and valve cuts off central passage at ordinary times, and Lower Half is the sealing device of stopper and bottleneck.Needn't take off stopper during pouring, valve can be opened automatically and allow water pass through, and when thermos bottle was erect, valve was accurately self-closing immediately again.This plug is easy to use, but water yield is little, and delivery port is exposed outside, and unhygienic, heat insulating ability is poor.

But the utility model provides a kind of durable global function insulation plug of being made of automatic open close plug shell, Nei Sai and enclosing cover.

The durable global function insulation of the utility model plug is to realize like this, it comprises the plug shell that matches with vessel port, the one end that matches with plug shell upper oral part is a delivery port, the enclosing cover that the other end is connected with the plug shell by hinge, be fixed on the hollow interior plug that has passage on interior its bottom of enclosing cover and the sidewall, the motion stops that is arranged in plug and cooperates with bottom air vent, generally interior plug bottom is made arc surface, motion stops adopts glass or non-toxic plastic bead, the passage of plug bottom in the perpendicular timing of vacuum flask bead can be sealed automatically is to increase its heat insulating ability.Insulation plug with cooperating of vessel port can be, at plug shell infraoral sealing ring is set, and in the groove on the embedding infraoral outer wall, the rubber seal that with the cross section is shape is for well.The plug shell inserts in the vessel port during use, rubber seal sealing-plug shell on it and the space between the vessel port inwall.The insulation plug also can be to be threaded with cooperating of vessel port.

The dividing plate of band passage can be set in the cavity of the durable global function insulation of the utility model Sai Neisai, interior plug cavity is divided into lower chamber, the passage on the dividing plate communicates 2 air chambers, so that balance inner air and outer air pressure, current are unobstructed when making pouring, and heat insulating ability is better.

The durable global function insulation of the utility model plug advantage is simple in structure, and vacuum flask is mixed this insulation plug, needn't take off stopper during pouring, opening and closing voluntarily, use very convenient, and sanitation and hygiene, good heat preservation performance, prolonged anti-work, can with each specification vacuum flask and the supporting use of other container.

Describe the utility model embodiment in detail below in conjunction with accompanying drawing.

Fig. 1-2: the utility model structural representation.

Embodiment 1:

The durable global function insulation of the utility model plug comprises plug shell 1, match with plug shell 1 upper oral part and by hinge 2 with fill in the enclosing cover 3 that shell 1 is connected, be fixed on the hollow interior plug 6 that has passage 4 on enclosing cover 3 interior its bottoms and the sidewall, interior plug 6 middle parts are provided with the dividing plate 5 of band passage 4, the glass marble 7 that cooperates with passage 4 is arranged at its bottom, is embedded with cross section on the plug shell infraoral outer wall to be

The rubber seal 8 of shape.

Embodiment 2:

Substantially the same manner as Example 1, difference only is to fill in the shell infraoral screw thread 9.

Claims (2)

1, a kind of durable global function insulation plug, it is characterized in that comprising the plug shell that matches with vessel port, the one end that matches with plug shell upper oral part is a delivery port, the enclosing cover that the other end is connected with the plug shell by hinge, be fixed on the hollow interior plug that has passage on interior its bottom of enclosing cover and the sidewall, the motion stops that is arranged in plug and cooperates with bottom air vent.
