Cover of container for storing food
Technical field
The present invention relates to cover of container for storing food, can effectively utilize the liner sealed container interior.
Background technology
As shown in Figure 6, when generally being used for forming circular container body 22 and lid 23 in the container 21 of storage food, the circular pads 24 that engages with lid 23 is the inner wall surface 25 of contacting container main body 22 closely, thus sealed container interior.
At this moment, liner 24 engages in such a manner, and anchor portion 26 is inserted in the circular groove 26 that is formed in the lid 23.Smooth surface is processed into so that improve closed contact power in the closed contact surface 28 of liner 24, makes it obtain the sealing effectiveness that requires.
But, if adopt conventional cushion 24, when closing containers covered 23, liner 24 was accepted pressure and distortion, container body 22 inner wall surface 25 are under pressure consumingly and seal.
Inboard and the outside at container body since opening is formed on air flows valve on the lid 23 communicate after, when lid 23 during from container body 22 separation, it is too tight that the user feels.Pop noise takes place when opening lid, makes lid open the people and feels very bad.
In addition, because the structure of liner 24, liner 24 may separate with lid easily when cover closing or unlatching.
Brief summary of the invention
Correspondingly, the object of the invention provides a kind of lid of container for storing food, can overcome the problem that runs in the traditional handicraft.
Another object of the present invention provides a kind of lid of container for storing food, wherein container cover can be smoothly from separating by seal liner leak free container body without any pop noise, and seal liner can stably engage, and seal liner is seldom broken away from.
For achieving the above object, in cover for sealed container, described lid comprises the liner that is engaged in lower lid surface so that engaged and sealing container body inside face top closely, and comprise being designed to and when close cap, cut off the airiness valve that is communicated with between internal tank and the outside, and prevent from when opening lid, to form vacuum at internal tank, a kind of lid of container for storing food is provided, wherein on liner closed contact surface portion, forms the small recesses on a plurality of similar golf surface.
On liner inner edge fixed surface part, form slit so that liner is bonded on the lower lid surface according to the interval of rule.The liner connecting element has a plurality of outshots, is formed on engagement groove on the lower lid surface and prevents that liner from deviating from thereby pass slit and insertion.
The small recesses of liner forms with caustic solution.
Brief Description Of Drawings

Concrete embodiment
Preferred embodiment of the present invention is described with reference to the accompanying drawings.
Fig. 1 is the elevation cross-sectional view of illustrating according to container cover of the present invention, and Fig. 2 is the backplan of illustrating according to liner of the present invention, and Fig. 3 is the section-drawing of illustrating according to liner main portion of the present invention.
In addition, Fig. 4 illustrates to be suitable for fixing liner connecting element planar view according to liner of the present invention, and Fig. 5 is the elevation cross-sectional view of illustrating according to liner connecting element of the present invention.
From leak free container cover 1 lower surface 2 outstanding two vertical walls 3 and 4, wherein two vertical walls are concentric circles.Annular engaging groove 5 is formed between two vertical walls 3 and 4.
Liner 6 is placed on the bottom of two vertical walls 3 and 4.Liner is formed by almost the fixed surface part 7 and the closed contact surface portion 10 of level, thereby part 10 rises from inner wall surface 9 tops with certain inclined degree and closely contacts sealed airspace with container body 8 inner wall surface 9 tops.On closed contact surface portion 10, form a plurality of small recesses 11 with the embossment shape that is similar to the golf surface.Here, small recesses 11 can form with corrosion or injecting molded method.
A plurality of arcuate slots 12 respectively have certain width corresponding to engaging groove 5 width, form according to certain interval between mutually in horizontal fixed surface portion 7 upper edge circular arc shaped portion.
Liner 6 is fixing by liner connecting element 13.A plurality of fixed salients divide 14 vertically to give prominence to from liner connecting element 13, and wherein each fixed salient branch has and arcuate socket 12 same size and certain cross sectional shapes.Fixed salient divides 14 to pass the arcuate slots 12 of liner 6 and closely insert the annular engaging groove 5 that is formed between vertical wall 3 and 4.In above structure, even when being pulled corresponding to liner 6 exterior fixed surface parts 10, liner 6 by the fixed salient of liner connecting element 13 divide 14 catch and stably support, liner can not be deviate from from lid 1.
In the present invention, cover for sealed container 1 covering container main body 8, thereby and airiness valve 15 be closed and cut off air admission.Thereby the closed contact surface portion 10 of liner 6 is by inner wall surface 9 sealed airspace of oppressing of container body 8.Under above state, even the user attempts to open lid 1, owing to, can not easily open lid in the certain vacuum of the inner formation of container body.
Therefore, when customer requirement is opened lid 5, must mention and open airiness valve 15.Extraneous air makes the easier disengagement of lid by open airiness valve 15 input pod main bodys 8 thereby make internal tank no longer form vacuum.
In the present invention, small recesses 11 is formed on the closed contact surface portion 10 of liner 6 by caustic solution, the area of contact for inner wall surface 9 is reduced, thereby lid 1 can easily be opened.When the closed contact state that discharges for inner wall surface 9, easily from tight joint, discharge owing to the air that is full of makes groove 11, and prevent pop noise.In the present invention, described is bulge, but also can be suitable for such as certain shapes of containers such as rectangular vessels.
As described above, be suitable for having a plurality of small recesses that form with caustic solution based on the liner closed contact surface portion with container body inner wall surface closed contact sealed airspace, it is shaped as the embossment shape that is similar to golf.Therefore, when from the container body portion during from lid, liner can easily separate, and lid is also easily separated.In the present invention, might work as liner and closely engage at it and prevent when described inwall separates under state of container inner wall that any pop noise from taking place, thereby improve product reliability.
, the present invention do not depart from its spirit or basic feature because can implementing in various ways, should be appreciated that above-mentioned example is not limited by any details in the above description, unless otherwise prescribed, therefore but should be broadly interpreted as in the spirit and scope that in claims, define, and all fall into the variation and the modification of situation that claim satisfies and limit or are equivalent to things satisfied like this and limit and will be comprised by claims.
