Abstract

A packaging container with variable volume. According to the design scheme provided by the utility model, the container includes a side wall of the container, a bottom of the container and a cover of the container, and is characterized in that: there are several ring-shaped creases on the side wall of the container, and two adjacent folds When the container shrinks, one circle of creases expands to the outside of the container side wall, and the other circle of creases shrinks to the inside of the container side wall. The folded side wall has a certain bearing capacity. The utility model uses a retractable structure to make a packaging container to reduce the volume of the packaging during transportation, storage, sale and use, thereby saving costs and being convenient to use.

Description

A kind of packing container of variable volume

Technical field

The utility model belongs to a kind of packing container, specifically a kind of telescopic packing container.

Background technology

The packing of existing instant food mainly is bowl (bucket) dress or soft plastic bag dress.The former by bowl (bucket) body of truncated cone-shaped, go to the bottom and the double lid paper of making trade mark is formed.The latter forms straight forming when attal by the heat-sealing of a slice plastic sheeting.Wherein, bowl (bucket) dress form is to put into food and condiment in the bigger bowl (bucket) of volume, processes food to pour boiling water and must leave bigger space in the container.Though this packaged form gives the customer with convenient to a certain extent, but because volume big, take up room also greatly, give and carry and use and all bring inconvenience, increased produce and transportation in cost, the compressive strength of package is not high, deforms easily in the use.Soft plastic bag dress form is that food and condiment are packed in the plastics pillow pouch, must prepare a container in addition during use and could process (brewing) to food, greatly reduces the comfort feature of product.Because soft plastic bag can not carry substantially, thus content be easy to because of extruding cracked.Need refrigerate in the packaging product of the direct processing in back at some other, use present technique also can solve the problem that need reduce storage space.

Summary of the invention

The purpose of this utility model is to design a kind of packing container of variable volume, utilizes a kind of telescopic version to make packing container, with the volume of minimizing package in transportation, storage, sale and use, thus the saving cost, the convenient use.

According to design plan provided by the utility model, this container comprises the sidewall of container, the end of container and the lid of container, it is characterized in that: the folding line that some circle annulars are arranged on the sidewall of container, two adjacent circle folding lines are when container shrinks, one circle folding line is to the expansion of the outside of container side wall, and another circle folding line shrinks to the inboard of container side wall.

The profile shape of container side wall is made of several vee shapes.Can bind round the endless belt of avoiding container freely to stretch in setting on the container on container when container is contraction state, the length direction of this endless belt is identical with the flexible direction of container.The tearing port that is easy to open is arranged on the endless belt.On the sidewall of container, handle is set.The sidewall of container and the end of container, perhaps are formed by connecting by the heat-sealing form by one-shot forming.

The utility model has the advantages that: because container side wall adopts the folding retractable structure, replace integral type that present convenience food packages uses fixedly barreled structure and soft plastic bag assembling structure, so can reduce packaging volume, reduce circulation cost, keep comfort feature.For barreled, also can reduce raw materials consumption; For soft plastic bag dress, also can effectively reduce content pressurized and damage of causing in transportation.

The specific embodiment

As shown in the figure: container is by sidewall 1, the end 4 and cover 5 and form, and the folding lines of some circle annulars are arranged on the sidewall 1 of container, and two adjacent circle folding lines are when container shrinks, and a circle folding line is to the expansion of the outside of container side wall, and another circle folding line shrinks to the inboard of container side wall.Sidewall after folding has certain load-carrying capacity.As a kind of concrete version, the profile shape of container side wall 1 can be made of several vee shapes.

When being contraction state, container can bind round the endless belt 2 of on container, avoiding container freely to stretch in setting on the container, the length direction of this endless belt 2 is identical with the flexible direction of container, this endless belt 2 both can print product trade mark, be again the parts of fixed container when being in folded state.The tearing port 3 that is easy to open is arranged on endless belt 2.On the sidewall 1 of container, handle is set, moves and use with convenient.The sidewall 1 of container and the end 4 of container, can perhaps be formed by connecting by the heat-sealing form by one-shot forming, to guarantee sealing.During use, this endless belt 2 is enclosed within on the container after the contraction, it is circumferentially identical with the flexible direction of container.

This product adopts a kind of telescopic version, can effectively reduce the volume of package in transportation, storage, sale and use, and is cost-saved, the convenient use.Be specially adapted to the packing of instant food such as instant noodles, convenient rice flour noodles and the packing of some refrigeration fast foods.

Container utilizes the overlapping reduction container height between the folding line on the container side wall 1 when shrinking, reduced packaging volume, sees Fig. 2; Be fixed in contraction state with the soft endless belt 2 of moulding again.During use, endless belt 2 is torn off along tearing port 3, because the elastic reaction of container material, folding sidewall stretches automatically; Or, have the container of volume greatly thereby form with the folding line that pulls out container, and see Fig. 1, conveniently brew food or carry out other processing.

The compressive state of packing can be kept in the endless belt before tearing, and as the trade mark of product in order to sign, promote products.
