Description

A kind of wide-mouth Large Copacity hot-filling bottle

Technical field

It the utility model is related to a kind of hot-filling bottle technical field, the particularly hot-filling bottle of Large Copacity.

Background technology

Hot filling refers to after the bottling of high temperature full irrigation cover product immediately, is then cooled to normal temperature under air-tight state (25 DEG C or so).Density of the beverage in hot filling is less than the density under normal temperature, in the case where filling amount is certain, is drunk in bottle The increase of material density necessarily causes the reduction of volume, forms certain vacuum.Beverage density vary with temperature it is bigger, in other words Beverage volume is bigger with temperature change change, and the vacuum in hot-filling bottle is bigger.By beverage exemplified by 88 DEG C are down to 25 DEG C, its Volume contraction is about 3.2%, and as beverage filling is discontented in hot-filling bottle, the density that water is more than due to the rate of change of the density of air is become Rate, its shrinkage factor have a certain degree of increase.Therefore hot-filling bottle needs to meet：(1) heat resistance, hot-filling bottle it is heat-resisting Performance can solve by improving bottle wall PET crystallinity；(2) resistance to interior negative pressure, mainly by the plate deformation of hot-filling bottle come Offset；In general, the plate of hot-filling bottle is surrounded by reinforcement structure, as triangle position is strengthened above and below rib muscle between plate face, plate Muscle forms basket structure and plays very strong supporting role, and plate could be deformed effectively, reduces bottle inner volume, improves the pressure in the bottle, reaches Internal and external pressure balance.But after the capacity of hot-filling bottle becomes big, existing structure is difficult to meet the needs of intensity, resistance Shape ability relative drop, after hot-filling bottle heat fills cooling, it is easier to which Delta Region is recessed up and down for the deformation of rib muscle, plate between causing plate Phenomena such as sunken, the flat folding of plate region or hot-filling bottle become ovalisation.And the bottleneck of existing hot-filling bottle is all smaller, big In the case of capacity, less bottleneck can cause in-convenience in use.

Utility model content

The technical problems to be solved in the utility model is：There is provided a kind of combination property more preferable hot-filling bottle structure.

The solution that the utility model solves its technical problem is：A kind of wide-mouth Large Copacity hot-filling bottle, includes bottle Mouth, main bottle body and bottom of bottle, the main bottle body include bottleneck and body, and the bottleneck is connected with bottleneck, and the body is held in the mouth with bottom of bottle Connect, the external diameter of the bottleneck is not less than 115mm, and the body is provided with multiple back-shaped reinforcements, the middle part of the bottleneck, bottle The joining place of the joining place of neck and body, body and bottom of bottle is equipped with the concave reinforcing rib of annular.

As the further improvement of above-mentioned technical proposal, the back-shaped reinforcement includes what multistage gradually caved inward Back-shaped step.

As the further improvement of above-mentioned technical proposal, the depth of the concave reinforcing rib is 4.5-5.5mm.

As the further improvement of above-mentioned technical proposal, the edge of the bottom of bottle includes the first of multiple triangles and strengthened Second reinforcement of muscle rectangle.

As the further improvement of above-mentioned technical proposal, the quantity of second reinforcement is twice of the first reinforcement, First reinforcement and the second reinforcement even circumferential are distributed in bottom of bottle, and are interspersed with one between two the second reinforcements Individual first reinforcement.

The beneficial effects of the utility model are：The utility model is worked by devising back-shaped reinforcement on body When, the negative pressure formed after hot content natural cooling in bottle is directly acted on back-shaped reinforcement face, makes back-shaped reinforcement Face directly toward bottle axle center uniform shrinkage, keep whole body will not be by atmospheric pressure；And bottleneck external diameter reaches more than 115mm, Facilitate filling.
