Description

Flexible pipe discharge end hermetically-sealed construction

Technical field

The utility model relates to a kind of flexible pipe that can be used for carrying liquid or lotion material, and is special relevant with flexible pipe discharge end hermetically-sealed construction.

Background technology

Flexible pipe has in light weight, use and convenient carrying, application is extensive, can be used for cosmetics, daily necessities and medical packaging etc., its structure is normally by body and cooperate the pipe lid of the body mouth of pipe to constitute, pipe covers and body mostly is the structure of screw thread or bayonet fitting, will manage lid during use and open, and will manage the lid lid after the use tightly; But flexible pipe transportation or be subject to the external force extruding when carrying causes the material in the pipe to overflow from the mouth of pipe, not only besmirches the pipe lid, and influence is used and be attractive in appearance, and the while also pollutes and wastes material.

The utility model content

For overcoming above-mentioned deficiency, the utility model provides a kind of flexible pipe discharge end hermetically-sealed construction, makes that the tight back of soft tube cap ferrule is good, material spill and leakage not.

For reaching above-mentioned purpose, the technical solution of the utility model is:

A kind of flexible pipe discharge end hermetically-sealed construction, this flexible pipe is made up of body, silicagel pad, end plug and pipe lid; Be equipped with screw thread on the outer wall of the mouth of pipe of described body, and form one on the inwall desired location of the mouth of pipe at interval, this is interval with and is communicated with the perforate of body in-to-in, with this as discharging opening, around a perforate flange protruding upward, the inwall of the mouth of pipe is provided with the card edge near protruding on the port again at interval; Described silicagel pad is located in this flange, and its middle part forms a catch, and the position in the spaced apart hole of corresponding body is provided with open-work around this catch; Described end plug activity is located on the mouth of pipe of body, is absorbed in a corresponding deep gouge that cooperates this flange on the end face of its phase line up, and a material hole is offered at the middle part, is equipped with convex tendon on the outer wall of this end plug, and forms a limiting block edge above convex tendon; Described pipe is covered with the thread segment with mouth of pipe screw thread fit, and moulding one step on the inwall desired location.

Adopt said structure, the utility model is by the setting of silicagel pad, screw the pipe lid after, can make the material hole of silicagel pad sealing end plug, prevent that flexible pipe from being pressed the material that causes in the pipe to overflow by mistake, be convenient to the transportation of flexible pipe and carry, use more convenient, safety and sanitation.

The specific embodiment

The embodiment of a kind of flexible pipe discharge end of the utility model hermetically-sealed construction, as shown in Figure 1, 2, flexible pipe 10 covers 4 by body 1, silicagel pad 2, end plug 3 and pipe to be formed.

The top of described body 1 is the mouth of pipe 11, be equipped with screw thread 12 on the outer wall of the mouth of pipe 11, and formation one interval 13 on the inwall desired location of the mouth of pipe 11, be provided with several at the middle part at interval 13 and be communicated with body 1 in-to-in perforate 14, with this as discharging opening, supply ccontaining silicagel pad 2 around each perforate 14 ring flange 15 protruding upward on the interval 13, the inwall of the mouth of pipe 11 is provided with card along 16 near protruding on the port again; Described silicagel pad 2 middle parts form a catch 21, and the position in the spaced apart hole 14 of corresponding body is provided with open-work 22 around catch 21; Described end plug 3 activities are located on the mouth of pipe 11 of body 1, but be absorbed in the deep gouge 31 of the aforementioned ring flange 15 of a corresponding matching on the end face of its phase line up, and the position of middle part corresponding silica gel pad catch 21 provides a material hole 32, this material hole 32 leads to brush or the ball that end plug 3 tops are provided with, be equipped with convex tendon 33 on the outer wall of this end plug 3, and above convex tendon 33, form a limiting block edge 34, end plug 3 is to combine with body along 16 by suppressing the convex tendon 33 that makes end plug 3 card by the mouth of pipe when installing, and makes the retaining edge 34 of this end plug 3 and 11 of the mouths of pipe have certain clearance a after installing; Described pipe lid 4 is provided with the thread segment 41 that cooperates with the mouth of pipe 11 screw threads 12, and moulding one step 42 on the inwall desired location.

As shown in Figure 3, screwing pipe covered 4 o'clock, pipe covers 4 thread segment 41 and is screwed into along the screw thread 12 of the mouth of pipe, and make pipe cover the retaining edge 32 of the step 42 ejection end plugs 3 of 4 inwalls, making end plug 3 move to retaining edge 32 in the mouth of pipe is resisted against on the mouth of pipe 11, when being moved down by ejection, end plug 3 forces the silicagel pad 2 in its end face extruding ring flange 15 this moment, make silicagel pad 2 elastic deformations make the material hole 31 of the catch 21 shutoff end plugs 3 at silicagel pad 2 middle parts, blocked the passage that material flows out in the body 1, the material when this moment, body was subjected to any extruding in the pipe can not overflow from material hole and besmirch the pipe lid.

As shown in Figure 4, open pipe during use and cover 4, the silicagel pad 2 recovery of elasticitys this moment material hole 31 of shutoff end plug 3 no longer, the extruding body, the material in the body can be flowed out for use through the open-work 22 of silicagel pad 2 material hole 31 by end plug 3 by perforate 14.

By said structure as can be known the utility model by the setting of silicagel pad, screw and manage when covering, can force end plug to move downward extruding silicagel pad, make the material hole of silicagel pad sealing end plug, prevent that flexible pipe from being pressed the material cause in the pipe to overflow by mistake and besmirching the pipe lid, be convenient to the transportation of flexible pipe and carry.
