However, in the practice of the application of disposable snack boxes, it has been found that plastic container processes and equipment are largely divided into blow molding and injection molding. Because of the complexity of the thread structure and the thin wall thickness of the disposable lunch box, demoulding is difficult, and only blow moulding equipment can be selected for production. However, the full-automatic blow molding production equipment is high in price and few in manufacturers, and in order to produce the novel leak-proof disposable lunch box by using the injection molding equipment and the injection molding process with low production and investment conditions and more manufacturers, the other sealing scheme is simplified and designed under the condition that certain sealing performance is guaranteed so as to adapt to injection molding production.

Background

At present, countless commodity liquid or liquid-containing commodities are packaged by using plastic or paper containers, and the great popularity of the beverage packaging and takeout industries also leads disposable plastic bottles and meal boxes to be consumed once every day in an astronomical digital scale.

Therefore, disposable plastic packaging waste is generated every day, countless. Since a more environment-friendly and cheaper alternative material cannot be found for a while, the inventor's idea is that even if one cup or bottle is provided with one gram of plastic, the improvement is achieved, and the practicability is increased and the improvement is achieved under the condition that the plastic is not used much.

SUMMERY OF THE UTILITY MODEL

The core of this scheme has designed inside and outside double container mouth, and simultaneously to down several millimeters at the container mouth, along the eminence under inside and outside container mouth, the plane of same height inwards extends into the annular plane of less diameter from outer container mouth, and planar thickness needs slightly thin to keep better ductility and elasticity, at less diameter, for example the diameter reduces several millimeters department, does the interior container mouth wall of round diameter decimalm again. The height of the inner container opening is slightly higher than that of the outer ring bottle opening, so that when the container cover is covered, the container cover moves downwards firstly, when the container cover is contacted with the top of the inner container opening, the downward movement needs to be continued, at the moment, pressure is generated between the container cover and the inner container opening, because the elastic container top wall and the annular plane connected with the inner and outer container opening walls generate elastic deformation and try to restore to the original shape, the sealing performance is achieved between the container cover and the inner container opening, when the bottle cover is pressed against the pressure to move downwards continuously until the inner and outer container openings are level, the container cover is screwed, when the bayonet on the outer container cover is clamped into the buckle on the outer container wall until the bayonet is clamped to the bottom, the outer container opening container cover generates slight sealing performance, and the inner container opening container.

Take the application of the utility model in disposable plastic snack boxes as an example. An internal and external double-container port with high inside and low outside is adopted. The mouth of the outer container and the cover are connected by a buckle.

The container cover adopts an inner container cover structure and an outer container cover structure. The container mouth adopts an inner and outer double-container mouth structure, the container mouth with a high inner part and a low outer part is used, the inner container mouth is used for generating sealing performance with the container cover, and the outer container mouth cover is connected by a buckle to fix relative positions.

The horizontal plane wall is connected with the horizontal plane at the position a plurality of millimeters below the top of the container mouth and at the horizontal plane height between the inner container mouth and the outer container mouth. The container cover is arranged on the edge of the outer bottle cover, an empty opening and a bayonet are reserved, and the bayonet is designed to correspond to the outer container opening so as to clamp the outer container cover.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 shows an inner-high outer-clamping dual container mouth, in this embodiment, a 1-1 inner container mouth wall with a height several millimeters higher than that of an outer container mouth, a 1-2 lower outer container mouth wall with a height 1-3 integrated annular horizontal plane walls connecting the inner container mouth and the outer container mouth, and a buckle on the 1-4 outer container mouth wall for clamping an outer container cover jointly form the inner-high outer-clamping dual container mouth.

2-1 outer container cover wall, 2-2 inner container cover wall, 2-3 container cover top wall, 2-4 opening bayonet used for clamping container opening buckle on the outer container cover wall, 2-5 lower height notch on the outer container cover wall, which jointly form the container cover of the inner-high outer-clamping double container.

When the container cover is closed, the lower-height notch on the wall of the outer container cover 2-5 is opposite to the lower-height notch on the wall of the outer container opening 1-4 for clamping the buckling position of the outer container cover.

Because the height of the inner container mouth wall 1-1 is slightly higher than the outer container mouth wall 1-2. When the container cover is integrally moved downwards, the top wall of the 2-3 container cover is firstly contacted with the container opening wall in the 1-1 container cover. The cap then presses against the inner finish wall 1-1 and continues to move downward, while the 2-3 top wall of the container cap and the 1-3 integral annular horizontal wall connecting the inner and outer finish will simultaneously deform slightly, due to the nature of the plastic, which is an elastic deformation that causes pressure between the inner finish wall 1-1 and the 2-3 top wall of the container cap, thereby creating a seal. The cap continues to move downward until 1-2 of the outer container mouth wall also contacts 2-3 of the container cap top wall.

At the moment, the bottle cap starts to rotate, the bottle cap and the bottle mouth do relative rotation movement, the buckle used for clamping the outer container cap is arranged on the wall of the outer container mouth 1-4, and the buckle used for clamping the buckle of the container mouth is clamped in the notch on the bayonet of the notch arranged on the wall of the outer container cap 2-4. And continuously rotating the bottle cap until the buckle used for clamping the outer container cover on the wall of the outer container opening of 1-4 is clamped in the bayonet on the opening bayonet used for clamping the buckle of the container opening on the wall of the outer container cover of 2-4.

At the moment, the relative position of the bottle cap and the bottle mouth is fixed. The top wall of the 2-3 container cover and the inner container opening wall of the 1-1 generate better sealing performance, and the top wall of the 2-3 container cover and the outer container opening wall of the 1-2 generate certain sealing performance.

Any modification, equivalent replacement, improvement and the like made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
