Description

A kind of vacuum bag that need not bleed

[technical field]

The utility model relates to a kind of vacuum bag, relates in particular to a kind of vacuum suction device that do not need and also can make bag be in the vacuum bag of vacuum state.

[background technology]

Vacuum bag has been widely used in the daily life, and the cotton-wadded quilt that it can will store etc. is compressed to 1/3 of original volume, is very suitable for carrying and convenient placement of people.But present vacuum bag all needs vacuum suction device, the mouth of bleeding of pump bowl or dust collecting fan for example: and must be provided with the supporting mouth part of bleeding on the bag, these have all caused, and part is not many, assembly is complicated, and is laborsaving when bleeding, flow is little, and the effect of bleeding is undesirable; Also cause simultaneously processing inconvenient, the productive costs height.

The closing device that the vacuum bag opening part is provided with comprises raised line, groove and the pressing block that cooperatively interacts on the back plate of bag, during use, compress left and right sides back plate and drag with pressing block, raised line and groove fasten just salable, but existing pressing block all is just directly to have dragged from left and right sides back plate after the pressing, when use next time again fit get on, like this, pressing block is easy to lose, during next time use, if there is not pressing block will make raised line and groove fit good, time-consumingly require great effort again, very inconvenient.

The utility model improves at above shortcoming.

[utility model content]

The purpose of this utility model is to overcome above-mentioned vacuum bag bleed assembly complexity, the unfavorable deficiency of the effect of bleeding, and a kind of simple in structure, easy to use, vacuum bag that need not air extractor is provided;

Another purpose of the present utility model is to overcome above-mentioned vacuum bag pressing block to lose, cause the deficiency of using inconvenience, the vacuum bag that provides a kind of pressing block can not come off easily.

The utility model is to adopt following technical proposals to realize:

A kind of vacuum bag that need not bleed comprises bag, closing device; Bag is provided with outlet passageway, and outlet passageway is made up of upper and lower diaphragm, is covered with oily goo in the outlet passageway and upper and lower diaphragm is clung; Outlet passageway one end communicates with the bag inner chamber, and the other end communicates with the external world;

The aforesaid a kind of vacuum bag that need not bleed, described outlet passageway is that the upper and lower diaphragm semitight by bag forms for twice, the first road semitight and passage of second road semitight formation spaced apart, the opening of the opening of the first road semitight and the second road semitight staggers and is arranged on the both sides of bag; The opening of the first road semitight communicates with the bag inner chamber, and the opening of the second road semitight communicates with the external world;

The aforesaid a kind of vacuum bag that need not bleed, described outlet passageway are the passages that is formed by the outer upper and lower diaphragm of bag, and passage one end communicates with the bag inner chamber, and the other end communicates with the external world;

The aforesaid a kind of vacuum bag that need not bleed, the closing device of described bag comprise left and right back plate, raised line, the groove on the left and right back plate at bag sack place and the pressing block that is linked in left and right back plate periphery; The middle part of pressing block inboard is extended with anti-flake, and anti-flake is arranged between the left and right back plate and is limited the position of slip by the sealing band on both sides, sack place;

The aforesaid a kind of vacuum bag that need not bleed, two inboard leg walls of described pressing block are provided with and above-mentioned raised line, the cooresponding pressing convex tendon of groove location.

Compared with prior art, the utlity model has following advantage:

Bag is provided with the outlet passageway of unidirectional exhaust, presses bag just can realize vacuumizing as long as push or roll up, and is easy to use, the exhaust efficiency height; And need not air extractor, also need not establish the mouth of bleeding on the bag, it is very simple that structure becomes, and saved manufacturing cost greatly;

Pressing block is limited between the sealing band on both sides, sack place and slides, and can not come off, and helps long-time use, and it is time saving and energy saving, convenient to use later on; Its parts simple in structure, as not have complexity can not increase manufacturing cost simultaneously.

[specific embodiment]

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

A kind of vacuum bag that need not bleed comprises bag 1, closing device 2.

Wherein, bag is provided with outlet passageway 3, and outlet passageway is made up of upper and lower diaphragm, is covered with oily goo in the outlet passageway and upper and lower diaphragm is clung; Outlet passageway one end communicates with bag inner chamber 11, and the other end communicates with the external world.

Outlet passageway 3 can be that upper and

lower diaphragm

12,13 semitights by bag form for twice, the first road semitight and passage of second road semitight formation spaced apart, the opening 17 of the first road semitight and the opening 18 of the second road semitight stagger and are arranged on the both sides of bag; The opening 17 of the first road semitight communicates with bag inner chamber 11, and the opening 18 of the second road semitight communicates with the external world.

Outlet passageway 3 also can be the passage that is formed by the outer upper and lower diaphragm of bag, and passage one end communicates with bag inner chamber 11, and the other end communicates with the external world.

Oily goo surface tension in the outlet passageway is big, viscosity is big, and the diaphragm up and down of outlet passageway is sticked together, and stops entering of outside air.

During use, earlier clothing is put into bag, seal sack then, firmly press down bag or press bag to outlet passageway direction volume, the air pressure in the bag increases, and progressively spreading oil goo glues the outlet passageway that holds together, and gas is discharged from the outlet that communicates with the external world; When the bag inner air pressure just often, oily goo is inhaled outlet passageway again together sealing rapidly.Outside air can not enter like this, can only discharge, and is equivalent to the check valve that can only give vent to anger.If once do not drain, we can repeat above process.

Wherein, the opening part of bag is provided with closing device 2, and closing device comprises left and right back plate 21,22, raised line 23, the groove 24 on the left and right back plate at the sack place of bag and the pressing block 25 that is linked in left and right back plate periphery; The middle part of pressing block inboard is extended with anti-flake 26, and anti-flake is arranged between the left and right back plate and is limited the position of slip by the sealing band 14 on both sides, sack place.

During use, compress left and right back plate and drag with pressing block, raised line and groove fasten, and be just salable; Anti-flake matches with the sealing band on both sides, sack place, thereby pressing block can only be slided between sealing band and can not skid off and come off.

Can be provided with on the two inboard leg walls of pressing block and above-mentioned raised line, the cooresponding pressing convex tendon 27 of groove location, raised line and groove are better fastened.
