CN2683545Y - Polyfoam packing box - Google Patents

Abstract

The present polyfoam packing box such as used for packing aquatic products and other polyfoam packing box used for thermal-insulating and leak-proof are mostly made into rectangular parallelopiped mould, which can be only orderly deposited in empty polyfoam packing box transporting and storing and occupy a great amount of transporting and storing volume, waste the transport capability and storing capability and increase the cost of manufacturers and users. The utility model provides a polyfoam packing box, owing to the box body adopting station-shaped mould and the box opening with a big bottom of the station shape, when the differential value between the inner edge of the big bottom of the station shape and the small bottom external dimension is large enough, a plurality of empty box bodies can be stack together and accommodated majority volume. The stack boxes can reduce empty boxes volume multiple times of stack empty boxes volume, and therefore, the utility model saves large transport capability and storing capability and reduces transportation cost and storage cost of empty boxes.

Description

The bubble wrap case

Technical field the utility model relates to a kind of bubble wrap case, especially at packed article need be incubated or the occasion of leakproof is used bubble wrap case.

Mostly the present used bubble wrap case of background technology is with the cuboid moulding as the bubble wrap case that is used to pack need insulation such as aquatic products or leakproof, in the transportation of cavity foam plastic packets vanning, storage, can only stack one by one, need take a large amount of transportations and storage volume, waste transport power and depot storage capacity, increased maker and user's cost.

Summary of the invention is at above-mentioned deficiency, and the technical problems to be solved in the utility model is exactly to reduce the shared volume in stacking of bubble wrap case empty van, and proposes a kind of this not enough bubble wrap case that remedied.

The bubble wrap case that the utility model provides comprises casing and case lid, and wherein the casing moulding is a platform shape, and the big end of platform shape is the case mouth up, and the inner edge size of the big end of platform shape casing is greater than handle outside size.

The bubble wrap case that the utility model provides, casing are truncated rectangular pyramids shape, and the difference on the inboard length of side in the big end of casing and the same side between the outside length of side of handle is two integral multiples of casing wall thickness.

The bubble wrap case that the utility model provides, casing are truncated cone-shaped, and the inner radius of the big end of casing and the difference between the handle outer radius are the integral multiple of casing wall thickness.

The bubble wrap case that the utility model provides, after the big handle of platform shape casing is harmonious with one heart, between outside inner edge of the big end and the handle surplus endless belt width be the position that can hold the wall box that stacks, this endless belt width is big more, the number of plies of the wall box that can hold on same horizontal surface is many more, the height that casing stacks the stacked casing in back is more little, and the angle of wall box and vertical line is also big more certainly.Make this endless belt width enough big guaranteeing that casing has under the condition of enough volumes and intensity, the angle of generally selecting wall box and vertical line is at 8 °-12 °.

The bubble wrap case that the utility model provides, wherein said case lid are the high less platform shape of platform, the big end of platform shape and the size of handle respectively with the big end of casing and the equal and opposite in direction of handle, the big end of platform shape downwards and the case mouth be harmonious.Case lid is moulding with platform shape, can increase the bearing capacity of case lid.

The bubble wrap case that the utility model provides, it is the platform shape moulding of arc that case lid adopts sidewall, with the bearing capacity of further raising case lid.

The bubble wrap case that the utility model provides, because casing adopts the moulding of platform shape, and the case mouth is the big end of platform shape, when the difference of inner edge size of the big end of platform shape casing and handle outside size enough greatly the time, several empty van bodies can stack and hold most of volume, its phase poststack can reduce the empty van volume that is several times as much as stacked empty van volume, thereby has saved a large amount of transport power and depot storage capacity, reduces the traffic cost and the warehouse cost of empty van.

Description of drawings Fig. 1 cuts open figure for the master office of looking of the utility model one embodiment empty van body when stacked;

Fig. 2 is the upward view of Fig. 1;

Fig. 3 partly cuts open figure for the master of the case lid of joining with casing when stacked looks.

It is 440 millimeters * 300 millimeters that specific embodiment embodiment 1, as shown in Figure 1, 2, the casing of bubble wrap case make bottom (platform shape handle), and oral area (the big end of platform shape) is 570 millimeters * 390 millimeters, and height is 300 millimeters a truncated rectangular pyramids shape.With on to go to the bottom all be 440 millimeters * 300 millimeters, height be 300 millimeters the cuboid packing chest relatively, as the case sidewall thickness at 7 millimeters, 10 folded mutually 2 volumes that empty van is shared, the positions that can save 8 cuboid empty vans of being equivalent to of empty van then.When trunkful divided list only to stack, the volume that the packing chest of 10 sloped sidewalls will be wasted was about 2 multiple spots.In empty van, trunkful and transportation once with stack once, always can save the volume of cuboid packing chest more than 5, can save 25% transport power and depot storage capacity.

As shown in Figure 3, it is 440 millimeters * 300 millimeters plane that case lid is made end face, mouthful is 570 millimeters * 390 millimeters, and height is 24 millimeters, and sidewall is the platform shape of cambered surface, cooperates with above-mentioned casing.

The casing of embodiment 2, bubble wrap case is a truncated cone-shaped, and case lid is a billiard table shape.
