The shape of container 1 and material are also unrestricted.For example, situation can be a kind of bag of shape, by the container 1 that the material of polymer plastic is made, comprise two sidewalls 2,3, it is made by the rectangular substantially sheet polymer plastic material of shape, and is connected by their three limits.Also might form additional bottom, wadding or other do not exceed the additional device of scope of the present invention.
The disengaged margin of sidewall 2,3 is made opening 4, is used for putting into the article of waiting to place container 1.
The present invention includes and make opening 4 keep open device in the loading stage.
In the situation shown in Figure 12 to Figure 14, these devices are positioned at the top of container 1, just in time in the edge of its opening 4.Yet these devices can be positioned at other positions, specifically can be on the sack bottom direction highly lower position.
To make opening 4 keep the preferred implementation of open device to carry out more definite description to being used for below.
More particularly, in Fig. 1, be marked into here 5 be the elongated member 5 of the rectangular shape that is flat substantially.
Fig. 2 shows the elongated member 6 of the complementation of device from the visual angle of overlooking.Elongated member 5 and 6 is of similar shape with size comparatively favourable.Their each end couples together by first junction surface 7 and second junction surface 8.
Preferably, make flexible band by polymeric material, and more advantageously be to make all elongated members 5,6, and make them form the flexibility that maintenance can provide enough bendings, realize making container 1 open structure shown in Fig. 6 and Figure 10, and can not cause the fracture of elongated member 5,6.
For example, can use the band of being made by the polymeric material of polypropylene type, more specifically the high density poly propylene of making for expressing technique.The employing of this material is especially favourable, because this material is found to have the mechanical property that is equal to fibre, its mechanical strength increases with the length of flexibility band.Like this, although otch at 7 places, first junction surface with selectively also form at 8 places, second junction surface, the mechanical strength of material all is enough to keep the continuity (coherence) between the elongated member 5,6.
The basic of the high density polyethylene (HDPE) of expressing technique preparation guaranteed to form residual layer in this side of otch for the mechanical specialities of stratiform, and the junction surface is under the condition of excellent mechanical intensity and flexibility.
Alternatively, can also use polyethylene or other to comprise the poly-mer of plant source poly-mer (biopolymer).Can also use non-plant transformed material.For example, can use bamboo.More properly, along its length direction cutting, make it only be left flexible slice on bamboo pole.The fiber that leads on the longitudinal direction has strong fiber properties, even also can provide mechanical strength for this later at the junction surface otch.Other timber, higher fibrous timber also may be utilized.In addition, another favourable possibility be by being connected to the junction surface the back side just the enhancement Layer of the reverse side of otch strengthen one of junction surface 7,8 or another or two.For example, can adopt the enhancement Layer of the adhesion type that has tissue layer.
Fig. 6 more clearly demonstrates the making of otch 10,11.With the vertical direction in the plane of the flexible belt surface of the base band of be used for making elongated member 5,6 on and to form otch at the whole width of band comparatively favourable.Otch 10,11 is made into prevents or to reduce coming off of material as far as possible comparatively favourable.Therefore, can guarantee that when open position, the abutting end of elongated member 5,6 crosses the thickness of elongated member 5,6 and joins, form linearity as shown in Figure 7 substantially.7 and 8 making breach are worthless at the junction surface.Otch 10,11 can be defined as be with separated into two parts simply.Particularly, can adopt thin blade to make otch.
Preferably, the thickness of otch be the band whole thickness 50% to 70% between.Thereby approximately being the thickness 2/3 of band, the thickness that makes otch make about 1/3rd remaining thickness of flexible portion formation of making the junction surface better.
Possible embodiment by shown in the mode of non-limiting example, can adopt following dimensional parameters:
The thickness of-flexible band, thereby also be the thickness of elongated member 5,6: between 0.2 millimeter to 0.8 millimeter.A kind of scheme that provides satisfactory result is to adopt the band of 0.4 millimeters thick; According to another kind of possibility, the thickness of band, being specially polyacrylic thickness is 1 millimeter.The recess of otch for example accounts for 80% of thickness so, that is to say it is 0.8 millimeter here.
-band width between 5 millimeters to 20 millimeters, for example 14 millimeters.In addition, the width of band goes out about 10 to the 40 times of effects that can give the people's satisfaction of sening as an envoy to greatly than its thickness.
The length of-elongated member 5,6: between 300 millimeters to 500 millimeters.
Be by independent band (band) when making when making opening keep open device, adoptable manufacture method is, band kept flat, and one face can be contacted, and 7 places arrange otch at the junction surface at least, and 8 that identical otch also is set is then more favourable at the junction surface.In the otch 10,11 at least one is to make by means of having the blade 14 that launches the profile of (splayed) towards the bottom.The start point of the outline line of blade 14 can be at 5 degree between 10 degree.This makes blade have the thickness of variation, and therefore makes the width of recess also change, and this width reduces to the direction of the bottom of otch 10,11.During in blade incision band, blade causes the plastic deformation of carrying material.Particularly, on the surface of the formation otch of being with, the projection 15 that forms material around this otch is favourable.This projection 15 has the profile that is preferably towards each edge increase of otch, and the thickness of band is being increased slightly near otch 10,11 places.This projection be to the maximum tape thickness 10% to 20% between, that is to say bringing of 1 millimeters thick said so 0.2 millimeter.
Projection 15 around the otch has increased the area of contact between the otch two edges partly, has therefore increased to make container remain on the effect of open position.Advantageously, this projection can not brought additional manufacturing step, because it forms simultaneously with otch.In addition, the thickness of the remainder of band does not change, and this has kept its flexibility, and avoids consuming excessively of material.
It should be noted, at least one the comprised viscosity part in the elongated member 5,6, when the latter was in first configuration, this viscosity part was positioned on the face in the outside of container 1.For example, viscosity part 12 can be made with the form of double faced adhesive tape, when wanting to close sack, can remove protective film from double faced adhesive tape.By elongated member 5,6 being folded to the wall 2 of container 1, thereby 3 the viscosity part 12 generation effect on this wall that at first makes realizes closing of sack.
Be used for making opening keep first configuration of open device shown in Fig. 1 to Fig. 7 and Figure 12 to Figure 13.In this case, elongated member 5,6 has the tendency that moves towards each other, and makes sack not stay open.On the other hand, the user is moved apart by making elongated member 5,6, realizes opening of container, and is extremely shown in Figure 7 as Fig. 4.In this configuration, the otch 10,11 at junction surface 7,8 is towards the outside of container 1.The flexibility of elongated member makes it recoil to make position.
Fig. 8 to Fig. 9 illustrates a kind of possibility from first configuration to second configuration.In Fig. 8, elongated member 5,6 is separated from each other.This does not need to expand to maximum at interval.So the operator can move two elongated members 5,6, is preferably the movement of symmetric mode, thereby it is turned.Nature, the result of this operation is, before in first configuration elongated member 5,6 towards the face in container 1 outside just towards the inboard of container 1.At this moment just become second configuration.This is corresponding to the view shown in Figure 10, Figure 11 and Figure 14.It should be noted that otch 10,11 is towards the inboard of container 1 at this moment.
Figure 11 more specifically shows 7 place's elongated members 5 at the junction surface, the relative position of two ends of 6, and the effect of the otch that forms at this place, this effect is to instigate element 5,6 to stride across (across) its thickness part adjacent, device is in makes the opening 4 of container 1 keep open open position.
Figure 14 shows whole effect well.As can be seen, the operator need not to apply at sack other power, and opening 4 is stayed open.
