Abstract

The utility model discloses an anti-seep paper container. A fan-shaped card board is curled and abutted to form lateral walls, and a circular bottom board with edges folding downwards is pasted below the lateral walls to form the anti-seep paper container, wherein the lateral walls and the bottom board are both double-layer structural card boards of which the internal layers are waterproof layers and the external layers are base paper layers; one of the straight line edges at both sides of the fan-shaped card boards is a waterproof structural edge of which the waterproof layers are 1 to 10 mm wider than the base paper layers, and the other straight line edge is an edge with flat batches; the waterproof structural edge is pasted on the edge with flat batches. The wider waterproof layer is pasted on the waterproof layer at the other side, and thereby effectively sealing the cross section of the base paper layer; liquid cannot leak from the cross section of the base paper layer for long. External moist air cannot enter the container during packing food, the preservation period of packed food can be effectively prolonged, and the shelf life of products can be prolonged.

Description

The antiseep paper-made vessel

Technical field

The utility model relates to a kind of container, relates in particular to a kind of antiseep paper-made vessel, as dixie cup, paper bowl, instant noodles packing box etc.

Background technology

Along with the development of world economy, the raising day by day of people's living standard, the continuous enhancing of environmental protection consciousness, the restriction plastic packing article uses and progressively comes into effect in countries in the world.Paper-made vessel as dixie cup, paper bowl, belongs to disposable product, has advantages such as safe and sanitary, recyclable utilization, will have the bigger market space.

The paper-made vessel of prior art, as dixie cup, paper bowl etc. is to be reeled by double-deck Paperboard cutting to dock, press from both sides an attached circular bottom plate to lower hem in the below reflexed again and constitute, its finished product top is set as suitable curling, with the intensity of strengthening cup and avoid burr to cut hand.Described double-deck cardboard comprises original paper layer and waterproof layer, and waterproof layer is in the inboard of paper-made vessel, can realize bonding between waterproof layer and the waterproof layer laminating bonding forming mutually but its sidewall is two sections to the circular bottom plate of lower hem and side cardboard.The sidewall of paper-made vessel will cut into fan-shaped cardboard earlier, see Fig. 1, Fig. 2, its edge of fan-shaped cardboard that this mode cuts all is neat stubble, and fan-shaped board rolls is to laminate bondingly between waterproof layer and the original paper layer around the docking site, sees Fig. 3, after the contain fluid time is long, liquid can permeate away from the section original paper layer, simultaneously owing to the seepage of liquid, can destroy the connection seam of cup, dixie cup is disintegrated, cause spilling leakage of glass interior liquid.

Summary of the invention

The purpose of this utility model is to improve the deficiencies in the prior art, provides a kind of cup to connect the firm antiseep paper-made vessel of seam.

The purpose of this utility model is to realize like this, a kind of antiseep paper-made vessel, by fan-shaped board rolls around to being connected into sidewall, a thereunder bonding circular bottom plate to lower hem constitutes, sidewall and base plate are that the inboard is that the waterproof layer outside is the double-decker cardboard of original paper layer, it is characterized in that: one of the straight line of fan-shaped cardboard both sides is the waterproof construction limit of waterproof layer than the wide 1～10mm of original paper layer, and one is neat stubble limit, the waterproof construction limit be bonded in neat stubble limit above.

The outside original paper layer of described double-decker cardboard can be the cardboard of sandwich non-bleaching in the middle of non-bleached paperboard, the cardboard of the non-bleaching of one side bleaching one side, whole bleached paperboard or the pros and cons bleaching.

The inboard waterproof layer of described double-decker cardboard is a kind of composite bed, and this composite bed can be high-resistant diaphragm and resin compounded layer, aluminium foil and resin compounded layer or paper and resin compounded layer.

The utility model compared with prior art has following distinguishing feature and good effect: the fan-shaped cardboard that the utility model constitutes sidewall connects the waterproof layer of seam than the wide 1～10mm of original paper layer; widely like this go out waterproof layer and stick on the waterproof layer of opposite side; effectively the original paper layer section is sealed; played double protection; the original paper layer that connects seam so just can not contact with the liquid in the container, and long-time contain fluid can not permeate away from the section original paper layer yet.The moisture in the outside can not enter internal tank yet during packaged food, can prolong the freshness date of guaranteeing the quality of packed article effectively, prolongs the shelf life of product.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described further.

Shown in Fig. 6,7,8, a kind of antiseep paper-made vessel, reel to being connected into sidewall by fan-shaped cardboard 3, a thereunder bonding circular bottom plate 4 to lower hem constitutes, sidewall and base plate are that the inboard is that waterproof layer 2 outsides are double-decker cardboards of original paper layer 1, one of the straight line of fan-shaped cardboard both sides is a waterproof layer than 5, one on the waterproof construction limit of the wide 1～10mm of original paper layer is neat stubble limit 6, waterproof construction limit 5 be bonded in neat stubble limit 6 above.

Preparation method of the present utility model is: as shown in Figure 4, at first will make both sides is waterproof layer dual layer discs paper material than the wide 1～10mm of original paper layer, and its width equals the vertical distance that 3 neat batches of limits of two fan-shaped cardboards, 6 radian directions are docked latter two waterproof construction limit 5 on the contrary.Then, when making paper-made vessel, to cut sidewall and baseboard material, wherein side-wall material will cut and be fan-shaped cardboard 3 shapes, as shown in Figure 5, the opposite butt joint of 3 neat batches of limits of two fan-shaped cardboards, 6 radian directions vertically is arranged on the dual layer discs paper material, arranges according to this mode and cuts fan-shaped cardboard 3, and a limit that has kept fan-shaped cardboard 3 is waterproof construction limit 5, also reduce simultaneously the generation of leftover pieces, reduced waste of raw materials.At last, fan-shaped cardboard 3 coiling butt joint waterproof construction limits 5 are bonded in the sidewall of the top formation truncated conical shape on neat stubble limit 6, circular bottom plate 4 is pressed into a circle to lower hem is bonded in the sidewall bottom, curling upper edge is made in the top of sidewall, antiseep paper-made vessel described in the utility model.
