Description

A kind of inner bead packing jar with upper cover

Technical field

It the utility model is related to packing container, more particularly to a kind of inner bead packing jar with upper cover.

Background technology

In the prior art, the storage of tealeaves is packed frequently with iron flask, and lid and the comparison that tank body can coordinate are close, this Sample lid is not easy to disengage from tank body, and tightness is good.But as the lifting of consumption idea, people increasingly grow tender of papery Jar carries out the packaging of industry.The lid of the jar of papery is generally using metal, plastics or the manufacture of bamboo and wood material.Due to tank The soft limitation of sub- material, and the general angle hawk of lid, are difficult to coordinate with tank body so comparing, to reach the effect of sealing, Generally protuberance is set in tank body oral area by the way of inner bayonet and it is caught in the groove of lid setting.

But the finite elastic of the jar due to papery, after multiple uses, the protuberance meeting set due to its oral area Deform upon and relax, be finally difficult to effectively be connected with lid composition.

Utility model content

The purpose of this utility model is to provide a kind of inner bead packing jar with upper cover.

One side according to the present utility model, there is provided a kind of inner bead packing jar with upper cover, including a bottom The tank body of portion's closing, the inside convolution of tank body oral area form an inwardly protruded inner bead of circle, and tank body oral area is additionally provided with a upper cover, Upper cover is removably attached to tank body oral area, upper cover lower part be equipped with the matched lid of inner bead, covered body wall for straight flange and It is connected with inner bead interference.

Using the inner bead packing jar with upper cover of above technical scheme, upper cover and tank body oral area are made using physical method Inner bead form removable connection, since the covered body wall of upper cover is straight flange, will not be formed between inner bead Big dilating effect, so as to greatly delay the time that inner bead deforms upon and relaxes, can be formed effective with upper cover The usage time of connection is longer.

In some embodiments, the surface that inner bead is in contact with lid is arc.Using the cooperation of cambered surface and straight flange, Contribute to the service life of extension inner bead.

In some embodiments, the internal diameter for the loop configuration that inner bead is surrounded along tank body oral area for lid outside diameter 93% ~ 98%。

In some embodiments, covered body wall is additionally provided with anti-skid device, and anti-skid device is used to increase lid and inner bead Between frictional force with increase upper cover fastening firmness.

In some embodiments, anti-skid device is set for covered body wall salient point either fin salient point or fin Top surface is in a cylindrical plane.

In some embodiments, anti-skid device is multiple fins that covered body wall is set, and fin is along covered body wall circumference Set.

In some embodiments, upper cover is wooden cover, bamboo lid or metal cover.

In some embodiments, tank body is one of metal foil, plastic film and paper or wherein any two kinds Laminated film encloses shaping.

Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings.

Embodiment 1

Fig. 1 to Fig. 3 schematically show a kind of curls inward with upper cover according to a kind of embodiment of the utility model Side packing jar.As shown in the figure, the device includes the tank body 1 of a bottom lock.

Wherein, the inside convolution of 1 oral area of tank body forms an inwardly protruded inner bead 11 of circle.

1 oral area of tank body is additionally provided with a upper cover 2.

Upper cover 2 is removably attached to 1 oral area of tank body.

2 lower part of upper cover is equipped with lid 21 matched with inner bead 11.

21 side wall of lid is connected for straight flange and with 11 interference of inner bead.

The surface that inner bead 11 is in contact with lid 21 is arc.Using the cooperation of cambered surface and straight flange, contribute in extension The service life of crimping 11.

The internal diameter for the loop configuration that inner bead 11 is surrounded along 1 oral area of tank body is the 93% ~ 98% of 21 outside diameter of lid.Therefore both may be used To ensure to form effective interference fit between lid 21 and inner bead, have and be unlikely to make inner bead 11 deform too quickly or loose Relax.

In the present embodiment, upper cover 2 is wooden cover, and tank body 1 is made of aluminium foil and paper composites.Implement in others In example, upper cover can also be bamboo lid or metal cover.Tank body 1 can also by one of metal foil, plastic film and paper or Wherein any two kinds of laminated film encloses shaping.

Using the inner bead packing jar with upper cover of above technical scheme, 1 mouthful of upper cover 2 and tank body are made using physical method The inner bead 11 in portion forms removable connection, since 21 side wall of lid of upper cover 2 is straight flange, will not with inner bead 11 it Between form excessive dilating effect, so as to greatly delay the time that inner bead 11 deforms upon and relaxes, can with it is upper It is longer that lid 2 forms the usage time effectively connected.

Embodiment 2

Fig. 4 schematically shows another capping according to the present utility model.As shown in the figure, the difference with embodiment 1 Part is that 21 side wall of lid is additionally provided with anti-skid device.Anti-skid device be used to increasing frictional force between lid and inner bead with Increase the firmness that upper cover fastens.Anti-skid device is multiple fins 211 that covered body wall is set.Multiple fins 211 are along lid 21 Side wall circumference is set, and its top surface is in a cylindrical plane.

In a further embodiment, multiple salient points that anti-skid device can also be set for covered body wall, the top of multiple salient points Face is in a cylindrical plane.

Above-described is only some embodiments of the utility model.For those of ordinary skill in the art, On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this practicality New protection domain.
