Abstract

The utility model provides a sealed container with an improved fastening sheet structure of a cover body. The cover body comprises a middle plane part and seal grooves respectively arranged at the edges of the bottom part of the cover body. Fastening sheets are formed in a way that joint parts arranged at the top part of the cover body extend outwards; and rubber layers are respectively compounded at the peripheries of the fastening sheets and the joint parts. At least one columnar bulge is generated at the position on each joint part, which is near each wrenching crease, and the bulges pass through the rubber layers to be exposed. The joint parts extend to both sides along the back faces of the seal grooves. According to the cover body with such the structure, the rubber layers are additionally arranged on the fastening sheets and the joint parts, and as rubber has high elasticity and good bending resistance, the sealed container is not easy to break off or strip after being repeatedly wrenched for a long time, and is durable in use.

Description

A kind of airtight container

Technical field

The snapping sheet that the utility model relates to the airtight container field, particularly a kind of lid that are used to store thing is the airtight container damaged of easy fracture not.

Background technology

The container of metal or plastic material is widely used in daily life, can on container, add upper cover usually, and container contents is sealed, and has health and the effect that increases storage period.Using the snapping mode is relatively more commonly used, convenient mode; Hinged snapping sheet on the container top that plastics are processed exactly; Form hanging member on the container outer wall, with the switching of snapping sheet and snap on the hanging member, lid just forms tight, stable fixing with container when covering.For guarantee the switching of snapping sheet flexibly, the linking the position and can be injection molded into very thin shape usually of snapping sheet and lid.This structure; In the use of providing convenience, its defective also is tangible: along with the in use prolonged and repeated switching of snapping sheet, itself and lid hinge point fracture with regard to as easy as rolling off a log; The back snapping sheet that fractures separates with lid; Container cover loses sealing function, can only change, the inconvenience that causes waste and use.

Summary of the invention

To the existing easy defective of damaging of its lid of airtight container that adopts the snapping mode, the utility model proposes a kind of airtight container, has improved snapping chip architecture, and its snapping sheet still is difficult for fractureing through prolonged and repeated switching.

The airtight container of the utility model; Comprise vessel, lid, the lid bottom sides is along being provided with seal groove, and the lid top evenly is provided with at least two junction surfaces; The junction surface stretches out; Form the snapping sheet, junction surface and snapping sheet hinge portion are thinner, are compounded with rubber layer at junction surface and hinge portion.

Above-mentioned airtight container is processed by plastic material, is made up of elastomeric material or thermoplastic elastomer TPE, TPR at the compound rubber layer of junction surface and articulated section branch.During use, be embedded in rubber weather strip at seal groove, cover cap is incorporated into the peristome of vessel; Seal groove aligns vessel wall portion, and rubber weather strip is contacted with vessel port, switching snapping sheet; The snapping sheet rotates downwards and inwardly; Fastener features along continuous straight runs above it is articulated on the circumferential rib of container outer wall face formation, and lid just is fixed on the container like this, makes internal tank form sealing.Sealing container engagement portion and snapping sheet hinge portion are thinner, and the folding line that formation can supply turn back during switching snapping sheet, produces bending at the folding line place, can produce stress at the hinge portion material internal.Because the articulated section is compounded with rubber layer, the stress of formation acts on plastic layer and rubber layer simultaneously.Elastomeric material inside has the molecular structure of cross-linked network, and the excellent elasticity performance makes that than the more difficult generation yield phenomenon of other material, the endurance failure cycle is longer under the effect of same stress.That is to say that because the junction surface is compounded with rubber layer, though make the snapping sheet in use by back and forth switching bending, therefore cause the possibility that fractures from folding line to reduce, useful life obtains prolonging.The bend resistance performance that the snapping sheet is excellent makes the lid of this airtight container be not easy to damage because of the fracture of snapping sheet, and is more durable.

Further, above-mentioned airtight container near the position of hinge portion, generates at least one columnar protrusions at each junction surface of lid, and columnar protrusions passes rubber layer and exposes.

Generate rubber and plastics composite bed with the mode that is laminated with rubber layer at frosting; When bending inwards the snapping sheet; Because drawing stress is also inconsistent in the deformation size that plastic layer and rubber layer produced, through repeatedly bending repeatedly, plastic layer and rubber layer just are easy to generate and peel off.This lid adopts the columnar protrusions structure to fix rubber layer.When the switching fastener, the inner tensile force that produces of rubber layer, tensile force can be to the columnar protrusions transmission.Columnar protrusions can produce the resistance that stops rubber layer to move under the effect of this tensile force, because columnar protrusions and plastic cover are one, this resistance can reduce the situation generation that rubber layer is peeled off from plastic cover widely.Therefore, further promoted the service life of lid.

Best is that extend to both sides along the seal groove back side at the lid top at junction surface recited above.

When inside switching snapping sheet, drawing stress makes rubber layer produce deformation, and deformation causes the contact surface of rubber and plastics to receive the effect of cross directional stretch power, and under this tensile force effect, two kinds of materials are also peeled off easily.If when the lid moulding, the junction surface is extended to both sides along the seal groove back side, be equivalent to increase the area of rubber part, thereby increased and the contacting of lid plastic layer, its adhesion effect will be more remarkable.Like this, under same tensile force effect, rubber layer is through be difficult for peeling off from lid after the switching repeatedly.

Above-mentioned airtight container can also be compounded with rubber layer at the periphery of snapping sheet, is connected with the rubber layer of hinge portion.

At the peripheral composite rubber layer of lid snapping sheet, can improve the adhesion strength of rubber layer, particularly junction surface and hinge portion rubber layer, more durable.Simultaneously, the feel of user when switching snapping sheet is better.

The airtight container of the utility model, its lid rubber layer adopt one of India rubber, butadiene rubber, isoprene rubber, poly-chloroprene rubber or poly-urethane rubber to generate.

Elastomeric material; Comprise India rubber, butadiene rubber, isoprene rubber, poly-chloroprene rubber or poly-urethane rubber; And thermoplastic elastomer TPE, TPR, all have excellent elasticity and antifatigue ageing properties, can be used as the composite material at this airtight container lid junction surface; Machine-shaping easily, easy to use after the moulding, durable.

Make the lid of the utility model, form lid, comprise planar section, seal groove and snapping sheet, then through injection molding, at the junction surface and the snapping sheet periphery composite rubber layer of lid with the plastic material injection moulding.Adopt this mode to form rubber and plastics composite bed, compare with the mode of using adhesion agent bonding plastics and rubber, its adhesion effect is more outstanding, and anti-fractureing property is excellent more.
