Description

A kind of crisper

Technical field

The utility model belongs to the antistaling container that a kind of family uses; Relate to and a kind ofly be suitable in refrigerator cold-storage food sealed to store and add at micro-wave oven pining for the box that holds as food, but refer to especially a kind ofly have the exclusive segment air and carry out the crisper that food is preserved so that produce negative pressure in it.

Background technology

China's invention 02160431.2 discloses a kind of antistaling container; This container adopt seal ring and latching device with the surrounding of container along sealing; And bring up an air gangway at the container cap, utilize the diaphragm that is contained in trip gear that the through hole of the sealing member that is placed in place, air gangway is sealed.It can be suitable for the sealing of food and preserve; Especially can be positioned over to play in the refrigerator and prevent to produce between the food effect that smell mixes; In addition; Can be easily and make the inner sealing of removing rapidly through trip gear, be adapted at micro-wave oven and add and pine for, with the blast that prevents possibly occur in the heat process as container.At present, this container extensively receives customer's welcome, and producer also produces to satisfy this kind requirement one after another.

But at first, such container in use still shows trouble, and the step of people's operation is comparatively loaded down with trivial details: one of which must be through latching device sealing edge, surrounding; Its two palpus rotates trip gear make diaphragm be positioned at the top of sealing member; It three must make the inner negative pressure that produces so that diaphragm is attached on the sealing member by suction through pushing capping.Secondly, the structure of such container is also complicated, and assembling is wasted time and energy, and must make diaphragm and with the diaphragm trip gear of packing into, labor hour can't reduce, and makes manufacturing cost high.Moreover, because assembling exists gap and diaphragm to expose, cause easily like the biting of cockroach and so on insect, and then cause the breakage of diaphragm.

The utility model content

The purpose of the utility model is to provide a kind of structure of crisper, and it utilizes draw ring that air inlet/outlet is sealed or opens in the time of through the rotation draw ring, and have simple in structure and convenience operation in the process that people use.

Its purpose is realized by following scheme:

A kind of crisper comprises box body, lid and seal ring, is characterized in, the recess of a circular arc is arranged on the lid, and said recess has an air inlet/outlet; Said air inlet/outlet is equipped with sealing member, has a through hole in the middle of the said sealing member; Also has a pull bar on the lid; Pull bar is loaded in the notch of lid by the two ends of a dwang; One segment is arranged in the middle of the said dwang; This segment is positioned at the top of sealing member through hole, by pull bar lift its plane of segment towards the sealing member through hole, and by the through hole that segment sphere kiss is affixed on sealing member of setting level of pull bar.

Like this, when lid covers box body, can be by seal ring with the gap closing between lid and the box body; Simultaneously, the gas in the box body is discharged from the through hole of sealing member, subsequently; Rotating tension bar makes pull bar be leveled to smooth placement, and the sphere that can make segment conforms to complete closed with the through hole of sealing member gradually; And when lid separates with box body, can lift pull bar earlier, make the sphere of segment leave the through hole of sealing member gradually; Then by the plane of the segment through hole towards sealing member, because there is the gap in the plane of segment with the through hole of sealing member, the interior air of box is in communication with the outside; Outside air can get into and replenish and inside can not form negative pressure; So lid can easily separate with box body under external force, particularly can upwards pull out along the pull bar that lifts; Make lid break away from box body, more simple in the operation.

Owing to can through hole closed, make that air is closed in the box, and then the trend that can utilize any between lid and the box body to separate to cause strengthening the inner space be with the generation negative pressure; Get final product the closed performance of enhanced leaktightness circle; Therefore, this crisper need not be provided with the latching device of locking seal ring, thus obtained crisper; Have good closure, be suitable for as the container that is stored in the food in the refrigerator.

This crisper is when when separating lid and box body and lift pull bar; The sphere of segment leaves the through hole of sealing member and transfers to be replaced by the plane of segment; Thereby air can exchange and obtain and replenish with the external world in the box, therefore, has eliminated negative pressure or has contained the generation of negative pressure; Not only lid can easily be separated, and this crisper is adapted in the micro-wave oven storing containers as heat food.

This crisper is worked as lid and is covered on box body; Can apply a downward application force at rotating tension bar forward direction lid; Lid is produced move down and the interior part air of extrusion box, and close through hole simultaneously, then can bring up the space of a few air in advance in box body inside; This is very favourable to storing its shelf-life of food prolongation, and also helps the closure of enhanced leaktightness circle.

The utility model crisper provides pull bar to people, can easily lid be pulled out from box body through pull bar, and is even more important; In the process of lifting and setting level of pull bar; Carry out the opening and closing of through hole simultaneously, therefore, through hole is opened or is closed to be included in by pull bar and opens or closes in the process of lid; Thereby can reduce control step largely, also just more convenient in the use.

The crisper of the utility model; The opening and closing system of through hole realizes through the segment on the dwang of pull bar; Because pull bar, dwang and segment can form through disposable die casting, therefore, the structure of this crisper can be simpler; Diaphragm need not be set, diaphragm holds parts and seal ring latching device etc., has advantage of low manufacturing cost.

In the such scheme, outwards form flange on the dwang in the outside; When the smooth placement of pull bar, the lid part relative with flange is formed with baffle plate on the lid; And flange contacts with baffle plate.Like this, when pull bar upwards lifts or sets level downwards, flange will break away from or contact baffle plate gradually; Can make pull bar when uncontrolled; Unlikelyly receive gravity effect and lift automatically or fall automatically, prior, because pull bar is set level the obstruction that needs the flange bottom to cross baffle plate; Thereby must apply a downward pressure to pull bar; This pressure acts on the deformation extruding part air that can utilize lid on the lid, thereby has had certain negative pressure in the box when through hole is closed, and need not must on lid, apply a pressure specially in addition in order to make it obtain negative pressure.Therefore, crisper has the effect that further simplifies the operation.

In the such scheme, on lid, form a cavity, said recess is formed in the cavity, and said pull bar also is loaded in the cavity.Like this, when the smooth placement of pull bar, pull bar can be positioned at cavity, thereby makes the basic maintenance level in lid surface, and is outstanding, can be so that collection and be suitable for transportation.

In the such scheme, pull bar system stretches out with the dwang bonded assembly, is convenient to point a kind of parts of being affectedly bashful from self body, perhaps similar parts; Obviously; Preferred scheme is, will stretch out and the dwang bonded assembly partly is made into annular, and this annular can open loop; Also can closed loop, also be that pull bar comprises draw ring.
