Abstract

The utility model discloses a thermos bottle cork, comprising a hollow main body and a cylindrical body. The cylindrical body is connected with the lower part of the main body and is communicated with a hollow chamber in the main body, the side surface of the main body is provided with a water outlet for communicating the hollow chamber in the main body and outside, a connecting position between the hollow chamber in the main body and the cylindrical body is provided with a downward concave cambered surface, and the concave cambered surface is matched with a movable sphere. When the utility model is utilized, water can be poured from a thermos bottle without needing to extract the cork, operation is convenient, direct contact between hands and the cork is avoided, and thus the thermos bottle cork is sanitary; when water is poured, the opening of the thermos bottle can not be opened completely, after water is poured, the cork can close automatically, and thus the thermos bottle cork has favorable thermal insulation effect when water is poured. The thermos bottle cork has simple structure and easy production, and the thermos bottle cork is not easy to be damaged.

Description

A kind of thermos cork

Technical field

The utility model relates to a kind of sealed piece in the neck or that pouring opening is interior or discharging opening is interior that is configured in, and particularly relates to a kind of bottle stopper of thermos bottle.

Background technology

Bottle stopper and the mode that external bottle cap combines is set outside bottleneck in the sealing of thermos bottle bottleneck is usually adopted and is provided with in bottleneck, in when falling hot water, need be opened external bottle cap earlier, bottle stopper in transfering to again, this mode has two shortcomings: first, troublesome poeration has been forgotten the lid external bottle cap sometimes or has been forgotten bottle stopper in the lid; The second, hand directly contacts with interior bottle stopper, thereby is unfavorable for the health of thermos bottle; The 3rd, in when falling hot water, bottleneck is in the state of opening fully, is unfavorable for hot water thermal insulating.

Occurred various bottle stoppers or bottle cap at present, its purpose all is for enhanced leaktightness, heat insulating ability, improves sanitation degree, and makes user's use easier.

For example, a kind of thermos cover of health is arranged, will block a shot outward links to each other with a lever with interior bottle stopper, press the overhanging end of lever, can realize opening simultaneously outer block and interior bottle stopper, thereby make opening process easier, thereby also avoid hand directly to contact health more with interior bottle stopper.But this thermos cover structure is comparatively complicated, and the junction of outer block, interior bottle stopper and lever is damaged easily and caused its activity dumb.This kind thermos cover is unfavorable for the shortcoming that is incubated when also having pouring.

For another example, the thermos cover that has will be blocked a shot outward and interior bottle stopper is fixed into one, can reach to open purpose convenient, that avoid hand and interior bottle stopper directly to contact, and its structure is also very simple, not fragile simultaneously.But, because outer block and interior bottle stopper be fixed together, can not be movable relatively, therefore higher to the accuracy of its relative position, so that can cooperate exactly with the outside and the inboard of bottleneck simultaneously, so its production required precision is higher, is difficult for realization.Be unfavorable for the shortcoming that is incubated when equally, this kind thermos cover also has pouring.

Diversified thermos cover is still arranged, but all do not apply because having many disadvantages.Therefore, more and more pay attention to current people under the situation of health, develop a kind of both conveniently use, simple in structure, can avoid the seal of the thermos bottle bottleneck that hand and bottle stopper directly contact again, be extremely important.

The utility model content

The utility model provides a kind of bottle stopper of thermos bottle, and its main purpose is unfavorable for the defective that is incubated when being to overcome aforementioned existing common thermos bottle bottleneck seal troublesome poeration, unhygienic, pouring.

Another purpose of the present utility model is to overcome the thermos bottle bottleneck seal or the complex structure of existing health or produces to go up and is difficult for the shortcoming that realizes, and is unfavorable for the defective that is incubated during pouring.

The utility model adopts following technical scheme: the bottle stopper of thermos bottle comprises a hollow main body and a cylindrical body, this cylindrical body is connected in the main body below and is connected with the cavity of body interior, the side of main body is provided with and makes body interior cavity and the extraneous delivery port that communicates, body interior cavity and cylindrical body connection are provided with a downward cancave cambered surface, cooperate on this cancave cambered surface to be placed with a mobilizable spheroid.

Described hollow main body constitutes by fastening a lid above the groove body and is duckbill, it protrudes the position is delivery port, close delivery port place, lid bottom surface is provided with the projection of downward extension, and the distance between this projection bottom and the groove body bottom surface is less than the diameter of described spheroid.

Described lid lower edge is provided with the bulge loop of downward extension, and this bulge loop outer peripheral face is provided with cannelure, and the inboard of described groove body top is provided with the snap ring that inwardly protrudes out, and this snap ring is sticked in the described cannelure.

Described cylindrical body comprises the inner cylindrical body and the flexible outer cylindrical body of rigidity, inner cylindrical body upper-outer circumference is distributed with the strip convex part of plurality of vertical direction, the taper that this strip convex part is big up and small down, the taper that the outer cylindrical body is slightly big up and small down, and it is external to be sleeved on inner cylindrical from the bottom to top.

Described delivery port lower edge is provided with outward extending colulus, and this colulus middle part is slightly to lower recess.

By above-mentioned description to the utility model structure as can be known, compare, the utlity model has following advantage: at first with prior art, the utility model need not to transfer to bottle stopper to carry out when making the applying hot water bottles pouring, and is easy and simple to handle, and avoided hand directly to contact, thereby health more with bottle stopper; Secondly, the utility model is when pouring, and the bottleneck of thermos bottle can complete opening, and has fallen behind the water, and bottle stopper seals automatically, thereby also has good heat insulation effect when pouring; The 3rd, the utility model is simple in structure, and is not fragile, and produces easily.

The specific embodiment

The specific embodiment of the present utility model, referring to figs. 1 through Fig. 6, comprise a hollow main body 8 and a cylindrical body 7, this hollow main body 8 is made of a groove body 1 and a lid 2, lid 2 lower edge are provided with the bulge loop 23 of downward extension, and these bulge loop 23 outer peripheral faces are provided with cannelure 21, the inboard corresponding snap ring 11 that inwardly protrudes out that is provided with of groove body 1 top, this snap ring 11 is sticked in the cannelure 21, thereby makes lid 2 and groove body 1 form a hollow main body 8.Lid 2 and front side, groove body 1 junction form a delivery port 5, and these delivery port 5 lower edge outwards protrude out and form a colulus 50, and the middle part of this colulus 50 is slightly to lower recess, so that pouring.
