Description
Technical field
The present invention relates to a kind of sealing box cover and its seal box, the sealing box cover of especially a kind of not rubber seal and
Its seal box, belongs to consumer goods industries.
Background technique
Crisper is a kind of daily necessity being commonly used in people's life, but current crisper is all to pass through rubber
Glue sealing ring realizes sealing.With the increase for using the time, rubber seal can follow the string, or even the feelings such as stain occur
Condition occurs influencing the hidden danger of food security.And sealing ring there are bacterium easy to breed, mounting groove is also easily stained with grease etc.
Dirt is made troubles to cleaning.
At the same time, after the food that crisper contains heat is cooling, it will form negative pressure in crisper, for traditional use
The more difficult opening of the crisper of rubber seal, is solved by adding ventilation valve at present, such as Lock & Lock Co., Ltd.'s public affairs
Department application No. is 2005100531923 patents.But such this body structure of ventilation valve is more complicated, gives crisper
Cleaning bring trouble.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of sealing box cover and its seal boxes, are not provided with air circulation
Valve had both made in the case where forming certain negative pressure or can be easy to open box cover；In addition, to be not provided with rubber close for the sealing box cover
Seal, but can be realized the good sealing effect of seal box；Entire seal box design is succinct, is convenient for cleaning.
The technical problem to be solved by the present invention is to what is be achieved through the following technical solutions:
A kind of sealing box cover, at least a pair of of the cover buckle (12) being connected including lid (11), with lid, it is characterised in that the lid
Body includes the controlled atmosphere structure (110) of at least one evagination.
Simple scenario, a kind of sealing box cover, at least a pair of of the cover buckle (12) being connected by lid (11), with lid are constituted, institute
The lid stated includes the controlled atmosphere structure (110) of at least one evagination.
The connection of cover buckle with the lid, which can be, to be connected non-removable, is also possible to removably connect.
Preferably, at least one circle seal land (13) of lid inner face (111) setting of the lid, the lid, sealing
Rib is connected.Preferably, the lid, cover buckle, seal land are prepared through injection molding.
Preferably, the controlled atmosphere structure is film layer structure.I.e. the controlled atmosphere structure is the film layer structure protruded outward；
It should be noted that also including that main body is protruded, the case where local inner concave.Preferably, the film layer structure is hemispherical film layer
Structure or class hemispherical film layer structure.The class hemispherical membrane structure layer includes semielliptical shape film layer structure, spherical crown film layer knot
Structure, close to hemispheric irregular film layer structure.It is further preferred that the film layer structure edge thickness intermediate thin.Further
Preferably, the film layer structure thinnest part with a thickness of 0.2mm -0.5mm.That is, the thickness of lid is larger, when from
When lid is transitioned into controlled atmosphere structure, thickness is from large to small.In general, from lid to the transitional region thickness change of controlled atmosphere structure
Larger, the body thickness of controlled atmosphere structure keeps uniform.
Preferably, the seal land is arranged in lid inner face close to edge.Preferably, seal land outer rim is from lid
The distance L2 at face edge is 1-10mm.It is further preferred that seal land outer rim is 1.5-from lid inner face edge distance L2
5mm.It is further preferred that seal land outer rim is 2-3mm from lid inner face edge distance L2.The seal land outer rim refers to
Seal land intersects with lid inner face and near the position at lid inner face edge.
Preferably, the cross section of the seal land is semicircle in class or is in class half 8-shaped.The class semicircle refers to
Shape is semicircle or shape close to semicircle, such as semicircle, half elliptic, rectangle and the semicircle figure for combining formation,
It is trapezoidal with the semicircle figure etc. for combining and being formed.That is, the head of seal land cross section has circular shape.
Preferably, the lid inner face includes two circle seal lands, and cross section forms folder between the two circle seal lands
Angle is the area of absence (131) of the class triangle of a.It is further preferred that the degree of the angle a is 60-150 °.Into one
Step is preferred, and the degree of the angle a is 80-120 °.It is further preferred that circular sliding slopes between two circle seal lands.I.e. two
The angle that the angle for enclosing seal land formation is a is fillet.
Preferably, at least one circle seal land is non-centrosymmetry setting about lid inner face central point.It is such
Setting can make box cover, not a position, can effectively delay fitting area when rotating after 180 ° with box body cooperation and before rotation
The decline of domain leakproofness.Also, when first time, cooperation cannot achieve sealing, it is also an option that 180 ° are cooperated again, increase
Cooperation has been added to realize the optional position of leakproofness.
Preferably, the height L1 of the seal land is 1-5mm.It is further preferred that the height L1 of the seal land
For 2-3mm.The height of the seal land refers to seal land free end to the distance of lid inner face.
Preferably, include between the seal land and lid groove structure (14).The setting of groove structure can make close
Envelope rib generates additional deformation when realizing sealing cooperation, and when cover buckle is opened, sealing box cover can obtain one and separate with box body
Power, convenient for the opening of box cover.
Preferably, the box cover is prepared by food grade materials.It is further preferred that the food grade materials are poly- third
Ene compositions.
Preferably, the sealing box cover does not include rubber seal.
A kind of seal box, it is characterised in that seal the box body (2) of cooperation comprising above-mentioned sealing box cover (1) and therewith.
When seal box makes sealing box cover be difficult to open due to negative pressure, controlled atmosphere structure is depressed, the air pressure in seal box rises, and is convenient for box
Lid is opened.
Controlled atmosphere structure described in this patent is connected with lid, and valve arrangement is not present.That is, after there is no opening
Make the valve arrangement of the atmosphere outside the air and box in seal box.
This patent has the beneficial effect that
1, controlled atmosphere structure need to only be depressed by setting controlled atmosphere structure when formation negative pressure is not easy to open the lid, it can be relatively light
Pine opens the lid.
2, by the setting of seal land, replace traditional rubber seal, thoroughly solve the bring due to setting of sealing ring
The problems such as health, cleaning.
3, by the setting of box cover structure, after opening cover buckle, the box cover of this patent can obtain one and separate with box body
Power, this power is bigger compared with traditional crisper, convenient for the opening of box cover.
4, due to not needing installation sealing ring, production efficiency is significantly improved, and cost is remarkably decreased.
