Abstract

The utility model comprises a bottle body which is divided into three parts, wherein, an upper bottle body which is circular is made of thick material; a lower body which is circular is also made of thick material; a middle bottle body which is arranged between the upper and lower bottle bodies is made of thin material. The upper, the middle and the lower bottle bodies are molded in integral injection. The utility model has the advantage that the size of the bottle body can be changed.

Description

Telescopic plastic bottle

The utility model provides a kind of plastic bottle, particularly a kind of telescopic plastic bottle.

Plastic bottle is seen everywhere, have cost low, in light weight, be easy to carry, be not afraid of and collide with and broad-spectrum plurality of advantages.

The plastic bottle that uses all is a solid shape generally at present, that is to say that after the production injection moulding was finished, the shape of plastic bottle just can not change.

If plastic bottle when not using, can fold or flexible, so that the space of being occupied when reducing the stock is the problem that the dealer considers always.

The purpose of this utility model is, a kind of telescopic plastic bottle is provided, and it has the advantage that can change the bottle size.

The technical solution of the utility model is: a kind of telescopic plastic bottle, it is characterized in that, comprising having:

One bottle; This bottle is divided into three stage structure, and a upper bottle body is circular, for thicker material is made; One lower bottle body is circular, and for thicker material is made: between this upper and lower bottle bottle in is arranged, bottle is made for thin material in this; This upper, middle and lower bottle is an integrated injection molding.

Wherein the top of this upper bottle body also includes section part in echelon, and a bottle neck is arranged on trapezoidal portions.

Wherein has screw thread on this bottle neck.

Wherein this lower bottle body has a bottom, and the sidewall of this lower bottle body is for going up little structure down greatly.

Wherein the junction of this upper, middle and lower bottle has a folding line of being convenient to turn down respectively.

For further specifying structure of the present utility model and feature, below in conjunction with embodiment and accompanying drawing the utility model is made a detailed description, wherein:

Fig. 1 is a structural representation of the present utility model, is the state that trails;

Fig. 2 is a structural representation of the present utility model, is the state that shrinks;

Fig. 3 is the section-drawing of Fig. 1.

See also Figure 1 and Figure 2, a kind of telescopic plastic bottle of the utility model, comprising having:

One bottle 10; This bottle 10 is divided into three stage structure, and a upper bottle body 1 is circular, makes for thicker material, and the bottle that is equivalent to prior art is not yielding; The top of this upper bottle body 1 also includes section part 11 in echelon, and a bottle neck 5 is arranged on trapezoidal portions 11, has screw thread on this bottle neck 5, and this screw thread is convenient to screwing togather of bottle cap, and described bottle neck is not limited to the structure of screw thread;

One lower bottle body 3 is circular, for thicker material is made, this lower bottle body 3 has a bottom 31, the sidewall of this lower bottle body 3 is for going up little structure down greatly, wherein the diameter of the bottom 31 of lower bottle body 3 is identical with the diameter of upper bottle body 1, and lower bottle body 3 upper part diameter are less than the internal diameter of upper bottle body 1, and the sidewall of lower bottle body 3 can be inserted in the upper bottle body 1;

Between this upper and lower bottle 1,3 bottle 2 in is arranged, bottle 2 is made (as shown in Figure 3) for thin material in this, is convenient to bending; This upper, middle and

lower bottle

1,2,3 is an integrated injection molding.

Wherein there is a folding line of being convenient to turn down 22,32 junction of this upper, middle and

lower bottle

1,2,3, and the effect of this

folding line

22,32 is that when bottle turned down, bottle is easy fracture not.

The utility model is extended configuration, as shown in Figure 1 in use.

The utility model is contraction state when not using, as shown in Figure 2.When needs use this plastic bottle, only need one to hold upper bottle body 1, another hand is scratched the bottom 31 of the bottle 3 of staying, and outwards stretching gets final product.

The utility model compared with prior art has following advantages:

1, onesize plastic bottle, the space that the utility model takies is little.

2, when the liquid in the bottle remaining 1/3rd lacks, bottle can be shunk, be easy to carry.

3, the variability that has because of bottle, desire to buy can stimulate consumer.
