Abstract

本实用新型涉及一种可消除负压的瓶盖，提供一种安全、便携的防负压瓶盖：由一外盖、一内盖、一密封圈和一单向进气阀片构成；外盖上部设一吊孔和一握把、中部向下凸设一内盖嵌环、下部周沿设有内螺牙，内盖嵌环上剖设有至少一个通气孔；内盖嵌固于外盖中部的内盖嵌环下，并用超声波熔接，内盖侧壁设一密封圈槽可嵌入密封圈，内盖底部设有数个进气孔，单向进气阀片嵌于进气孔下方可从下方封堵进气孔；瓶口外壁设有外螺牙与外盖下部周沿的内螺牙螺固，瓶口内壁与内盖之间的间隙由嵌于内盖侧壁的密封圈密封。吊孔和握把可便于携带；盖紧瓶盖后，瓶内的水和气不能溢出，但当瓶内产生负压时，外部空气可进入瓶内消除负压，性能可靠、使用安全。

Description

一种防负压瓶盖 
技术领域
本实用新型涉及一种密封饮水瓶盖，尤其涉及一种可消除负压的瓶盖。 
背景技术
目前使用的饮用热水瓶，其瓶盖多为完全密封的。将热水装入瓶内并盖上瓶盖后，随着瓶内温度降低，将产生较大负压致使瓶盖难以开启。为此，有如CN2631982公开的一种可消除负压的密封饮料瓶盖，其包括密封盖和吸嘴，密封盖上位于吸嘴的侧边开有一回气孔，回气孔中固定有一块橡胶片，橡胶片上开有一条切口。本实用新型的橡胶片弹性张力可以承受瓶体内液体的重量，防止泄漏；当瓶体内产生负压时，瓶体外的大气压力克服橡胶片的弹性张力，使橡胶片的切口张开，空气进入瓶体内而消除负压，液体可以顺利连续被吸出。该方案有结构简单、方便实用。其不足之处在于：装热水的瓶配用该盖时，会产生喷射现象，喷出的热水可能烫伤使用者，具有安全隐患，此外，该瓶盖没有涉及可携带的构造，其便携性较差。 
实用新型内容
本实用新型的目的是提供一种安全、便携的防负压瓶盖。其技术方案为：所述防负压瓶盖由一外盖、一内盖、一密封圈和一单向进气阀片构成；外盖上部设一吊孔和一握把、中部向下凸设一内盖嵌环、下部周沿设有内螺牙，内盖嵌环上剖设有至少一个通气孔；内盖嵌固于外盖中部的内盖嵌环下，并用超声波熔接，内盖侧壁设一密封圈槽可嵌入密封圈，内盖底部设有至少一个进气孔，单向进气阀片嵌于进气孔下方可从下方封堵进气孔；瓶口外壁设有外螺牙与外盖下部周沿的内螺牙螺固，瓶口内壁与内盖之间的间隙由嵌于内盖侧壁的密封圈密封。 
本实用新型的有益效果是：外盖上部设一吊孔和一握把，便于携带；盖紧瓶盖后，瓶内的水和气不能溢出，但当瓶内产生负压时，外部空气可经螺接部位从通气孔进入内盖，再通过单向进气阀片上方的进气孔进入瓶内消除负压，性能可靠、使用安全。 
附图说明
下面结合附图和具体实施例对本实用新型作进一步说明： 
图1是本实用新型具体实施例之分解状态示意图； 
图2是本实用新型具体实施例装配状态侧视图； 
图3是图2中A-A剖面示意图。 
图中标号所示为：1外盖：11吊孔，12握把，13内螺牙，14内盖嵌环，141通气孔；2内盖：21密封圈槽，22进气孔；3密封圈；4单向进气阀片；5瓶体，51瓶口，511外螺牙。 
具体实施方式
如图1所示：本实用新型由一外盖1、一内盖2、一密封圈3和一单向进气阀片4构成；外盖1上部设一吊孔11和一握把12、中部向下凸设一内盖嵌环14、下部周沿设有内螺牙13，内盖嵌环14上剖设有至少一个通气孔141；内盖2侧壁设一密封圈槽21可嵌入密封圈3，内盖2底部设有至少一个进气孔22。 
如图2所示：外盖1盖于瓶体5上部。 
如图3所示：本实用新型的内盖2嵌固于外盖1中部的内盖嵌环14下，并用超声波熔接，单向进气阀片4嵌于进气孔22下方可从下方封堵进气孔22；瓶口51外壁设有外螺牙511与外盖1下部周沿的内螺牙13螺固，瓶口51内壁与内盖2之间的间隙由嵌于内盖2侧壁的密封圈3密封。吊孔11和握把12，为携带瓶体5提供了便利；盖紧外盖1后，瓶体5内的水和气不能溢出，但当瓶体5内产生负压时，外部空气可经螺接部位从通气孔141进入内盖2，再通过单向进气阀片4上方的进气孔22进入瓶体5内消除负压，这样的构造确保本实用新型性能可靠、使用安全。
