Description

Container with foldable and contractile type sidewall and base portion

Technical field

The present invention relates to a kind of container, it can for example be used for preserving and therefrom distribute easily (preferably not needing utensil) food, such as pet food, baste, sour milk, custard etc. or other liquid or semifluid material, such as oil or grease, glue, resin.

Background technology

Consumer package is designed to consider function and outward appearance.For example, most of disposable sour milk containers are made by thermoforming plastic.A slice thermoplastic plastic is stretched as container shapes by thermoforming machine.This container generally is made up of circular or square side wall construction, with qualification have by periphery flange around the housing region of upper opening.Flange provides the position that is used for foil seal, engaging with thermoplastic plastic, thereby forms the openable lid of housing region.In this container some are arranged to its phase opposed side walls to be parallel to each other basically, although may have small gradient so that the Heat forming product can take out from thermoforming machine.Yet, if the sidewall of this container is parallel, empty container (for example add the building site and be carried to its packing ground) from it can not with identical container suit, to reduce when these containers are in vacant state, transporting its required gross space.

Disposable sour milk container may be also need they finish load and sealing after, one folded one stacking.In view of the intensity of each container side wall, the height that can reach this container heap has certain limitation.Container will have to have enough wall thickness, so that under the situation that the problem that container flattens under sidewalls flex and the weight accumulation effect in the above do not occur, realize stacking suitable or required height.Increasing wall thickness will increase the material cost of the container of each processing.For this wall thickness, need and can reduce, so that reduce the cost of product processed, and still can provide the container that has comparable intensity with container with smooth sidewall.

The edible of food that is loaded in the disposable model container finished by the use spoon usually.Spoon can directly be transported to food contents in eater's the mouth.Spoon is the further element that need be provided to make that content in this container is eaten.Because their high viscosity and/or gel character, sour milk and custard or for example those other food consumption products with jelly shape denseness be not to pour out fast from container or distribute in the efficient range arbitrarily.Therefore be necessary to use spoon to transport from container, if not most content.Can also see that the consumer package that is used for food containers has the food contents of making in the trend that can distribute under the situation of further instrument or utensil.Though some inviscid fluid or ungelled fluid products that are included in the container can be poured out from this container, sour milk or other similar food product products have the relatively poor characteristic of toppling over.This fluid may be newton or non-newtonian fluid, pure because its viscosity characteristics, and they may unnecessarily have this relatively poor characteristic of toppling over.For this reason, normally, use spoon allocated product content from container.The ability of the live part of the self-dispense contents of packing is by consumer package designer and processor's decision.

The recovery that comprises the container of the consumables also is the significant consideration in the package design.The smooth rectangular shape of sour milk container is not easy to its compression.For the efficient that promotes to reclaim, the compression of consumer package is a remarkable advantages.

The specific embodiment

With reference to Fig. 1, shown molded container 1.Molded container 1 is preferably made by Heat forming or moulding material, and its precursor forms is the sheet-form of this material.The deep drawn thermoforming machine can provide suitable molded surface can constitute as container described here so that the precursor sheet of material is heated and pressurized.Can also make container by injection moulding or vacuum forming or other appropriate process.Though in its most preferred form, container have between 100 and 250ml between the housing region of volume, but those skilled in the art should be appreciated that container can increased in size and reduce size, and still can realize with identical function described here and desirable characteristics.

Molded container 1 is by sidewall and basal wall or regional the composition.In the example depicted in fig. 1, molded container 1 is essentially quadrangular container, and this container has first pair of

opposed side walls

4,5 and second pair of opposed side walls 6,7.At least the second pair of

opposed side walls

6,7 comprises that respectively pretreated profile is to form the foldable and contractile type profile.This profile it is also conceivable that it is corrugated profile.Except can comprising the foldable and contractile type profile, preoperative treatment will be for a more detailed description hereinafter with the profile that forms the foldable and contractile type profile." V " type foldable and contractile type profile is most preferred form.

Base portion 8 is positioned at the centre and the bottom of

opposed side walls

4,5 and 6,7.

Base portion is arranged under

sidewall

4,5 and 6,7, and combines with sidewall and limit housing region 2.In the upper end of

sidewall

4,5 and 6,7 can be periphery flange 9.Yet periphery flange not necessarily.

This periphery flange 9 preferably is provided with around the opening 10 of molded container 1.Periphery flange 9 outwards launches from housing region 2 and

sidewall

4,5 and 6,7, covers 11 surfaces that can engage 12 so that provide.Periphery flange 9 can provide continuous and smooth basically face of joint 12, engages on this face of joint and covers 11.Lid can for example be a foil material, and can fix by allowing to cover the 11 common known technologies of peeling off from periphery flange 9.This released part ground illustrates with reference to Fig. 9.Figure 10 has shown 11 another form of covering.Lid (or its with periphery flange 9 fixing) can be and the permanent type that combines of periphery flange 9 formation.In the example of Figure 10, the opening 10 of molded container 1 partly exposes by outlet mouth and cap 13.Cap 13 can utilize and for example be threadedly connected to outlet mouth, with the opening of opening container and closed again when needed.

In the strippable paillon foil shown in Fig. 8 and 9 was arranged, strippable paillon foil can be to be used as the type of airtight container again.Known reclosable lid can be used in the present invention.

Opposed pair of

sidewalls

6 and 7 comprises and is preferably the surface texture that collapses the shape profile.Surface texture guarantees that sidewall has the characteristic that formation collapses the shape profile.Collapse the shape profile and be allow other sidewall 4 with 5 mutually the profile of extruding each other.

V shaped wheel is wide to be profile form most preferably.Alternately, profile can be arc as shown in Figure 27 and 28.

Preferably the foldable and contractile type profile can also be defined as the groove in other flat sidewall that are arranged on opposed

side walls

6 and 7.

These grooves or collapse structure vertically and preferably near or from being positioned at or the side wall lower ends of adjacent base 8, extend to or towards being positioned at or towards the upper end of the sidewall of opening 10.Yet with reference to Figure 30, the groove of

sidewall

6,7 does not need to extend to from base portion 8 fully the opening 10 of container as can be seen.In example shown in Figure 30, groove extends towards opening 10 from base portion 8, but no show opening 10 and stopping.In this state,

sidewall

5,4 phases still can take place each other compression, and the zone that groove is set in

sidewall

6,7 has promoted this compression.

Container shown in Fig. 1 provides two grooves 14 on each sidewall for opposed side walls 6 and 7.In alternative example, with as shown in FIG. 5 the same of example, opposed

side walls

6 and 7 includes four grooves.

For " V " type groove preferably, giving on the set a distance between

sidewall

4 and 5, and, will cause the angle (angle A) between the spike of the groove of groove and groove to increase towards 90 degree at the increase number of the groove on

sidewall

6 and 7 14 for any given depth of groove.Angle is the closer to 90 degree, the easy more extruding of container.Squeezing action will be described in more detail hereinafter.

Although the container of describing is generally square or rectangular planar shape, what can expect is, the present invention can provide circle or elliptical shape more container, and it still can comprise opposed

side walls

6 and 7, and these sidewalls comprise and collapse the undulations structure.For can with as the mode squeeze receptacle hereinafter described, the diametrically contraposition zone of this bulge can comprise and collapses structure.Figure 17 has shown this example.

With reference to Fig. 7, shown another distortion, wherein container is essentially rectangle plane figure.In the example depicted in fig. 7,

less sidewall

6,7 has comprised and has collapsed structure.Alternately, the major lateral wall of this rectangular shape container can comprise and collapses the undulations structure.

In most of preferred form,

sidewall

4 and 5 is an aspect.This sidewall can preferably not comprise any undulations structure that collapses, and can for example be straight or slight curving surface.

Be positioned at or, transition web 15 can be set towards the upper end of groove 14.It is straight from groove (planar view, angled with the straight edge of flange 9) transition with sidewall.Shown in groove be in the vee-type example, the transition web extends with the fore-and-aft tilt ground (when observing in lateral plan) of groove 14 basically.With reference to Figure 32, as can be seen, web 15 (illustrating with the virtual image) extends with the spike 116 of the groove 14 of sidewall and the fore-and-aft tilt ground of groove 117.

With reference to for example be the container of vee-type type depicted in figure 5 at groove, transition web 15 is a triangle.Should be appreciated that not necessarily triangle of (with reference to Figure 27 and 28, its further groove is the profile of varying cross-section) transition web.

Web 15 helps to form transition between the straight upper limb of groove 14 and periphery flange 9 or sidewall 6,7.In compression process, the transition from foldable and contractile type side wall profile (or through pretreatment profile with formation foldable and contractile type profile) to straight upper limb helps to provide required effect the container characteristic kinematic.Be positioned at zone 118 straight of transition web 115 and preferably basically continuously upper limb (as shown in Figure 32), transition web self and/or periphery flange 9 all extend along being arranged essentially parallel to compression direction, the opening that helps to guarantee container compresses unlike the base portion of container.

One or more this features help to guarantee that opening compresses unlike container base.Alternatively, their promote flange 9 to form arcs around housing region 2, and for example the same shown in Figure 11,12 and 13.With reference to Figure 31, the container shown in it is not included in the arbitrary structures element that opening upper edge compression direction PP extends continuously, and opening 10 will compress.Periphery 119 in this example (no matter whether flange has been installed thereon) will insert opening 10.

Web 15 (is in the leg-of-mutton preferred form at them) is the plane in form.Their plane preferably is parallel to the direction that applies compressive force PP.As a result, these webs provide resistibility to being compressed this zone.Especially at the upper limb 118 of web 15, web can adjoin basically mutually, and straight edge is parallel to the PP direction and forms.

Container of the present invention can be provided with or upper flange 19 can be set.Even under the situation that does not have upper flange 19, by realizing that as container described here compression provides opposing to opening part, to obtain the required form of container under compressive state.

When being provided with, upper flange 9 helps to provide extra opposing to the compression on the opening, also is provided for covering the leak free surface.The alternative form of flange 9 can be set according to the required characteristic of sealing or covering of container.

In preferred structure, web 15 helps to form the arc or the arc shape shape of periphery flange 9 in the base portion compression process.As shown in Figure 13, when base portion and

sidewall

6,7 compressions, periphery flange 9 is crooked.As with reference to shown in Figure 33, make periphery flange 9 be subjected to compressive force along equidirectional by the compressed container zone of exerting pressure along the PP direction.Because material of the present invention has elasticity, exists edge 128 to move close natural tendency.As the result of the straight line opposing that is provided by periphery flange 9 and/or edge 118 and/or web, previous straight edge 118 can draw closer together, but only bends to the result of bowed shape as shown in Figure 33 as edge 118.Distance X in compressed format than in that compressed format is not little.Help exposing the upper area of the housing region 2 of container like this, so that people realize more easily being convenient to take out and edible content near container by their mouth and/or tongue or spoon or spoon.

For edible content, when periphery flange 9 is in such bowed shape, does not run into or knock under the situation of periphery flange at people's nose, people's mouth or tongue can engage with the bottom of housing region more easily.Peripheral part (if be provided with, and periphery flange) is bending downwards, thereby has reduced the possibility of people's nose contact periphery (and flange), thereby and make people can near housing region before than the deep branch.And web 15 has been eliminated in the container compressed format at periphery flange 9 or any remarkable recess below it.

When periphery formed bowed shape, the exposure of

sidewall

4 and 5 upper area produced basic V-arrangement form as shown in Figure 11.So also help easily near container contents.The shallow V-arrangement form on

sidewall

4 and 5 top allows the people to shift the content that is placed on the container in the shallow V-arrangement sidewall areas easily.

With reference to Figure 14 and 15, line of weakness or weakening region 60 can be arranged on the periphery flange 9.Line of weakness or weakening region 60 preferably are arranged in the middle of

opposed side walls

4 and 5 basically.In the process of base portion compression or base portion extruding or periphery flange additional compression, by near the periphery flange upper edge in the zone of

sidewall

4 and 5 relative direction FF extruding periphery flange for example, line of weakness or weakening region allow periphery flange 9 to rupture at certain phase.Periphery flange 9 will cause periphery flange 9 to reduce its rigidity of structure significantly in the fracture at line of weakness or weakening region 60 places, so that it is compressed.This compression for example illustrates with reference to Figure 15, so that the zone of the periphery flange 9 of

close sidewall

4 and 5 is more close.Make container can be operated to such an extent that have container and be in significantly more compressed state under complete non-compression and the non-squeezed state like this.This compression has the vessel volume of reducing, thereby increases the advantage of efficient in any recovery of container.The compression container that for example is sent to recovery plant will need lower volume significantly in its transportation.

Provide the

opposed side walls

6 and 7 that collapses to improve the side wall strength of container 1.Owing to collapse structure, improved side wall strength to resist along the top to any bending of bottom direction applied pressure lower wall on container.Collapsing has increased total effective sidewall length, with and shape the resistivity of the opposing bending bigger than flat sidewall is provided.The increase of this intensity makes sidewall thickness to reduce.Thickness reduce to cause reducing of tooling cost.

Collapse structure and also be arranged to help the extruding of container.Collaborative with the foldable and contractile type sidewall that is arranged for container extruding purpose, base portion 8 preferably also has surface undulation portion 20, and this undulations helps the compression of base portion 8 when squeeze receptacle.This surface undulation portion has the fold of vertical characteristics or collapses the shape structure.Surface undulation portion 20 vertically preferably extends along the general closed planar that is parallel to first pair of opposed side walls 4,5.Surface undulation portion 20 preferably extends between second pair of

opposed side walls

6,7 basically.As shown in Figure 2, three such surface undulation bilge constructions 20 are provided.

The number of this surface undulation bilge construction 20 does not need (but preferably) corresponding with the number of the groove 14 that offers second pair of opposed side walls 6 and 7.This surface undulation bilge construction of enough numbers is provided to help compression base portion 8 when container pushes.

In most of preferred forms, when when base portion is seen in the below, surface undulation bilge construction 20 extends in the housing region recessedly., undulations 20 exceeds other substantitally planar base portions 8 downwards thereby preferably can not giving prominence to.

They can be the undulations (when compression and/or precompressed compression) of extending away from container.

As mentioned, the content that it is desirable to allow to be included in the container distributes under the situation that does not need additional means or utensil.The present invention allows

sidewall

4 and 5 to be taken to together and to realize above-mentioned purpose by sidewall 6,7.For example the power that is applied on

sidewall

4 and 5 by thumb and forefinger moves together opposed side walls 4 and 5.Collapse the undulations structure phase compression each other, and groove will reduce size when opposed

side walls

4 and 5 extruding.Base portion also will compress.

The volume that squeeze receptacle causes reduces effect will be at first discharges content by opening 10, outspokenly connects edible content for what the people used them.The content that any part that is retained in housing region reduces in the volume can be approaching easily by for example people's tongue or mouth, so that obtain remaining food contents from housing region.So just allow to realize easily near the content that has also all eaten basically in the container by the people.
