Abstract

A plastic, hot-fillable, blow-molded, singleserve container having a four-sided body. Three sides of the container include vacuum relief panels that can flex inwards when fluid in the container cools and contracts. In an embodiment of the invention, the rear panel is a vacuum relief panel that includes a raised island structure on which a label may be applied and supported. The left and right sides of the container also include vacuum relief panels. These left and right side panels can include, for example, ergonomic D-shaped depressions that allow a person to grip the container with one hand.

Description

But the grasping formula container of three sides decompression

Technical field

The present invention relates to plastic container, particularly the shape of this type of container and structure.

Background technology

As everyone knows, beverage is loaded in the plastic container usually and sells.This type of container can be disposable or reusable container.And, some beverage container of can packing into while hot usually.For example, some fruit juice or tea-drinking maker are with drink can when being approximately Fahrenheit 185 and spending.Immediately with beverage bottle capping and cooling.The beverage of cooling shrinks, and produces inner vacuum.In this case, to make container sustain or to allow in design because inner vacuum and " tightening up ", keep the grace of its appearance and modeling simultaneously.But can be used for the container of the liquid form product of splendid attire heat in this way is called as the container of hot filling.

All there is the problem of cooling shrinkage in the container of this hot filling technology of any employing.For the contraction problem, Comparatively speaking in design problem is less usually for bigger container (for example 42 ounces or more than) and less container.The sidewall of larger container is also inevitable bigger.Sidewall bigger during cooling is compared easier curving inwardly with less sidewall.Less container then problem is more.Less container (for example 16 ounces) must have less sidewall.Specific rigidity is stronger, more not flexible mutually with bigger sidewall for the sidewall of this class container.

Therefore, but be necessary to provide a kind of plastic container of less hot filling, the liquid cooling that the sidewall of container fills and can curving inwardly when shrinking within it.

Summary of the invention

The present invention is but a kind of hot filling, blowing mould are made, disposable plastic container, and it has the main body that is made of four sidewalls.Have relief (vacuum reliefpanel) in three sidewalls of this container, liquid cooling that can be in container also curves inwardly when shrinking.In one embodiment of the invention, rear wall is a relief, and it comprises the island structure of a projection, can be used for pasting and the carrying label.The left side wall of container and right side wall also have relief.This left side wall and right side wall can comprise the structure that meets human engineering, and the people uses the hand just can the grasping container like this.

Below in conjunction with accompanying drawing other purposes of the present invention and advantage and preferred embodiment are illustrated.

The specific embodiment

Below embodiments of the present invention is described in detail.In description, used specific term for the ease of clearly describing to embodiment.But the present invention is not subjected to the restriction of these particular term.Although following exemplary embodiment is described, should understand it only is effect up to explanation.Those skilled in the art does not break away from flesh and blood of the present invention and scope when adopting miscellaneous part and structure.

But the present invention is a kind of disposable plastic container with hot filling of the main body that is made of four sidewalls.For example, the capacity of this container can be 16 or 32 ounces, and the present invention is not subjected to the restriction of this capacity certainly.Three sidewalls of this container have relief, and its liquid cooling in container curves inwardly when shrinking.In one embodiment of the invention, rear wall is a relief, and it comprises the island-projection structure that can paste and keep label.The left side wall of container and right side wall also comprise relief.This left side wall and right side wall can comprise the structure that meets human engineering, allow to use a grasped container.In one embodiment of the invention, this ergonomic structure comprises that every side all has the depressed part of " D " shape.

Figure 1 shows that one embodiment of the present of invention.This container can use polyethylene terephthalate (PET, polyethylene terephthalate) or similar compounds manufacturing.Container shown in the figure 100 comprises a neck 120.In one embodiment of this invention, neck 120 is cylindrical.One end of neck 120 is a port part 110.The other end of neck 120 is a shoulder 130.Shoulder 130 has a top 127 and a bottom 133.The bottom 133 of shoulder 130 is right after main body 140.The front that container 100 shows is positive zone 160.The back side of container 100 is invisible in the figure.Be right after the bottom 150 of main body 140 shown in the figure in addition.

Figure 2 shows that the block diagram of the container of Fig. 1, can see the container side and the back side.Sidewall 210 is a relief, plays the effect that discharges vacuum.Among the embodiment shown in the figure, sidewall 210 comprises a depressed area, or is called depressed part 215.Be tracted inwards in the liquid cooling contraction process of depressed part 215 in container.In the present embodiment, depressed part 215 is the shape of letter " D ".In other embodiment of the present invention, sidewall 210 can have other the structure that meets human engineering.In the illustrated embodiment, around portion 212 around depressed part 215.In the cooling shrinkage process, also inwardly draw around portion 212.And, be independent of depressed part 215 around portion 212 and curve inwardly.

The sidewall (not shown) that opposite side is relative has similar curved configuration.These depression structures that sidewall has are convenient to the people and are used a grasped.

Also show the back relief 218 that is positioned at the back side among Fig. 2.Back relief 218 comprise by depressed part 220 around the island structure 230 of projection.Depressed part 220 around island structure 230 curves inwardly in the liquid cooling contraction process.

Figure 3 shows that the front view of container shown in Figure 1.Front side wall 160 has big rigidity comparatively speaking, and is not crooked or a small amount of bending only arranged in contraction process.Although front side wall shown in the figure 160 is provided with horizontal groove, the present invention is not subjected to the restriction of this structure.Other embodiment of the present invention can not establish these grooves.In one embodiment of the invention, front side wall 160 can be used for adhesive label.

Figure 4 shows that the lateral plan of container shown in Figure 1.There is shown relief 210 and " D " shape depressed part 215 and around the district 212.The side-looking situation of the depressed part 220 and the island structure 230 of back relief 218 is provided among the figure.

Figure 5 shows that the rear view of container shown in Figure 1.Except the sidewall 210 that part is shown, also show back relief 218 and island structure 230 and depressed part 220 among Fig. 5.

The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, though the present invention discloses as above with preferred embodiment, yet be not in order to limit the present invention, any those skilled in the art, in not breaking away from the technical solution of the present invention scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, but every content that does not break away from technical solution of the present invention, according to technical spirit of the present invention to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solution of the present invention.
