Abstract

The utility model relates to a hose container with valves. A membrane one-way valve is arranged at a position of the inner end of a discharge lip in a cavity, the middle part of a valve body which is provided with a slight arched flake is provided with a notch, and the circumference of the valve body is fixedly connected with a hose container. The utility model is made by rubber or plastics. The utility model overcomes the defects existing in the class of containers that air can easily enter the containers, the air is firstly exhausted when the containers are extruded again, and hoses of the back part can not be easily extruded. The utility model can prevent the air form entering, the use is convenient, the oxygenation of the air to materials can not be occurred, and the materials are not easily deteriorated.

Description

Hose container with valve

The utility model relates to the hose-like container of the plaster material of packing into, and particularly a kind of oral area is provided with the Hose container with valve of valve, and valve opening when container is squeezed is discharged material.

The general daily material of ointment shape (semi-liquid-like), as toothpaste, adopt flexible pipe container as packing, to be user-friendly to.Traditional flexible pipe container adopts soft metal manufacturings such as tinfoil paper and aluminium foil, after the container extrusion, because of aluminium foil does not have elasticity, container inner wall keeps pressing close to the state of material in the pipe, do not have air admission therebetween, when squeezing tube once more, paste still is easy to be extruded.For cost-cutting and saving metallic material, and stop material and metal to react, contaminated material, adopting plastics and rubber in recent years in a large number is raw material, makes hose packing.But because plastics and rubber have tangible elasticity, after staff loosened extruding to flexible pipe container, the tube wall bounce-back recovered not squeezed state.Tube wall and storeroom produced big space and formed negative pressure this moment, the pipe outer air is entered in the pipe internal pore by discharging opening, when extruded material again, what at first extrude is air, back segment ointment squeezes not come out, and will push ointment in the pipe to extrusion earlier, squeezes again, could extrude ointment, make troubles to the user; In the air admission pipe, can produce oxidation in addition, easily produce rotten material.

The purpose of this utility model provides a kind of Hose container with valve, it is made by plastics or rubber, advantage with plastic hose container, the plastic hose container can be overcome again and after extruding, air must be entered, squeeze time spent elder generation's air-out again, and back segment ointment is difficult for extruding the inconvenience that brings to the user, simultaneously also because of stoping air admission, avoid the oxidation of air to material, material is not perishable.

For achieving the above object, the utility model is taked following design plan: be positioned at the inner place of discharged orifice in the Hose container with valve and install the membrane type check valve, this valve is made with rubber or plastics elastomeric material, valve body is the sheet that arches upward a little in the middle part, there is a kerf at the middle part, the adjacent surface of otch should coincide, and its end face that arches upward is to discharged orifice, and valve body periphery and flexible pipe container are affixed.

The utility model is the same with original flexible pipe container, and by bottom (promptly relative with a discharged orifice end) plaster material of packing into, heating and pressurizing is sealed then.Material in the user need be with bag (promptly referring to flexible pipe container), the lid of the discharge gate of outwarding winding, behind the squeezing tube wall, material is washed open outside the otch, discharge discharged orifice at membrane type check valve middle part.After extruding stopped, discharge stopped immediately, and valve body otch adjacent surface recovers the shape that coincide, owing to there is not the gap, air can't enter in the container cavity.Though material is after use in the bag, because of charging into, no air forms negative pressure, but because of valve body is the shape that outwards arches upward, inside and outside differential pressure is counter to make the otch sealing more tight, and this pressure reduction only can make hose wall inwardly press close to plaster material, when pushing tube wall once more, material can be extruded swimmingly, brings convenience to the user, avoids existing flexible pipe container to enter air after extruding, elder generation's air-out when pushing again, the inconvenience that the back segment flexible pipe is difficult for extruding; Also avoid the oxidation of air to material simultaneously, material is not perishable.It has kept the advantage of plastic hose, has overcome its shortcoming again.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the structural representation of the utility model Hose container with valve

Fig. 2 is the end view of membrane type check valve

As shown in Figure 1 and Figure 2, this Hose container with valve is positioned at discharged orifice 1 inner place and installs membrane type check valve 2 in cavity, this valve body is the sheet that arches upward a little in the middle part, there is a kerf 5 at the middle part, the adjacent surface of otch should coincide, and its end face that arches upward is to discharged orifice, and the periphery of valve body and flexible pipe container inwall are affixed, said affixed be to say to bond, riveted joint or overlap with annular and to block.The cavity that an embodiment of the present utility model is a flexible pipe container constitutes by the crown cover 3 that has discharged orifice with body 4 two parts of crown cover coupling, the membrane type check valve places between crown cover and the body, and withstand by the periphery of body end with valve, crown cover and body are fixed together, perhaps with being threaded togather.Wherein the thickness of check valve is decided by the size of caliber, and as when caliber is 20 millimeters, the thickness of valve can be 1 millimeter, can increase to the 1.5-2 millimeter during enlarged diameter.

Claims

1, a kind of Hose container with valve, it is characterized in that: be positioned at the inner place of discharged orifice in the cavity and install the membrane type check valve, this valve is made with rubber or plastics elastomeric material, valve body is the sheet that arches upward a little in the middle part, there is a kerf at the middle part, the adjacent surface of otch should coincide, and its end face that arches upward is to discharged orifice, and valve body periphery and flexible pipe container are affixed.

2, Hose container with valve according to claim 1, it is characterized in that: the cavity of flexible pipe container constitutes by the crown cover that has discharged orifice with body two parts of crown cover coupling, the membrane type check valve places between crown cover and the body, and withstand by the periphery of body end with valve, crown cover and body are fixed together, perhaps with being threaded togather.
