Container weight indicator

The present invention relates to the utensil that weighs, referring to a kind of especially is the container that can be used for waste handling such as pattern, and it includes when it is raised, the power releasing member of indication container contents weight.

Increase and exhaust the soil that is fit to the landfill site with population, refuse collection and dispensing have become a serious global problem.Simultaneously, the concern of environment has been promoted the regulation that the practice is disposed in large-scale recovery and control, toppled over such as unsighted offshore.All these concerns are collected by rubbish and waste management becomes a processing far beyond the past complexity, and to abandoning the place of refuse and placement thereof, needing far is more control.

Guarantee the appropriate location front yard gurry that keeps house, need more personnel, and in a lot of situations, when the landfill site exhausted, discarded object must be carried distance more and more far away.This expression refuse collection becomes, and expensive day by day with continuing to become.One in order to separate the technology with the relevant expense that removes rubbish, and for foundation weight is collected these refuses, and charges to the user according to this.

Because rubbish is lost its identifiability matter when mixing, so obviously when its initial collection, must give weighing.Certainly, the existing various platform scales that can cooperate the roadside to collect and use, but complicated electronics even mechanical type pound claim with regard to regard to the property born and with regard to maintenance, all difficult problems are arranged all.In addition, do not need split-hair weight metering at least at present, for example extremely may be just enough near five pounds approximate number.Therefore still need not complicated platform scale.

Therefore, continue to need a kind of weighing container, storage as the enough device accurately for the economy of the used plastic bag of refuse collection purpose usually.A kind of ideal device will be for enough accurate, but on the meaning that need not complicated mechanical mechanism or electronics sensor then for passive.Utilize enough economic device, the burden of buying platform scale can be transferred to the rubbish source, but not refuse collection, thereby make former difficult system alleviate another demand may implementing on a large scale.

The purpose of this invention is to provide a kind of container with interior dress weight indicator.This container need not complicated mechanical formula or electronics or platform scale.

The invention provides one and have the container of interior dress weight indicator, and need not complicated mechanical formula or electronic weighbridge.At all embodiment, when mentioning container, one or more force-responsive elements are owing to the weight of container and content thereof is released.Then with reference to and each element near the numeric character of connection, the individual who mentions this container is the weight of budgetary estimate content immediately just.

In preferred embodiment, one bag be provided with the relevant mark impression of these elements and weight as between the band opened, each band surrounds the part around the bag at least.Directly the bag material below each reaches above the impression band gives local gathering and adheres to making it remain on the location, be raised until container, at this moment, if weight equals or exceeds a specified value of the digital marking, just be released with the element of this marking connection.But gravimetric value can be stamped on the aggregate material of releasing member.

Decide according to manufacturing technology, the material of container can be placed on the band of impression, and be attached to itself, make and to separate and need not other disconnected member.But, be the enhancement accuracy, but the independent power releasable material sheet of a band or arrowband form is added eyelet or thickness or changes in material, discharges at specified weight to guarantee it.Each band around container is preferably the weight associated different with, and all bands are arranged according to the order that increases digital gravimetric value, with the most close container bottom device of value of minimum weight connection.But, owing to only discharge in order to indicating a gravimetric value around the material of a specific impression band, and when discharging, do not cause any tearing or opening of finding out, so band can reach with any series arrangement with any interval at bag material, for example, all bands can be all opened the top near container between closely.

The present invention illustrates a kind of method of making container, this container has an indicator of opening strips, in view of the above a flexible material sheet is placed on the cylinder mold, this mould has several sections, and between all sections gapped in, but allow a power releasable material to be capped, and be attached to each band of assembling like this.

In an alternate embodiment, all conditions and are suitable for cooperating on the fillet that container uses one not on container.At this embodiment, fillet has two ends, and the one end is attached to container or in order to binding container, and the other end is booked for mentioning.Releasing member is positioned at several points along this main fillet in this example, and has ring to allow all elements to discharge, and makes the two halves of disconnection keep connecting simultaneously, to guarantee that container does not fall to ground.In another alternate embodiment, fillet is got the form of a rope, but clamped and insert the release force ring be positioned at along its length.

Fig. 7 is the diagram of a strong ring as the rope of releasing member.

Please refer to accompanying drawing, Fig. 1 shows a container by the refuse bag configuration that comprises flexible sheet, and this bag summary is shown it with 12.Be many bands of opening 14 around bag, illustration 16 shows the wherein amplification profile of a band in addition.Please refer to this figure, directly this above band container material 18 and directly the container material 20 below this band stretch each other mutually, to making the material that comprises this band itself become gathering, and present a kind of spiral outward appearance shown in 22.This material that folds comprises the marking value (invisible in Fig. 1, as to be shown in each accompanying drawing of back but know clearly in addition) of a relevant weight.Once material section 18 and material section 20 are furthered mutually each other, the band of a power releasable material 24 just is adhered on the material 22 that folds, and adheres to along dotted line 26.Power releasable material 24 can be the indivedual arrowbands of continuous strip form, and is designed to when bag is mentioned, and it is all on band the time to cause the pulling force of enough sizes to add, and just row is torn.About the details of power releasing structure also with see be shown in after each accompanying drawing.

In order to the technology that the power releasable material is adhered to mark impression band several patterns can be arranged, comprise and use bonding agent, pin seam, heat or ultrasonic welding, or any combination.Only main points are drawn back when showing the weight of container contents when the power releasable material, and adhering to of power releasing member and container material needs its integrality of maintenance.Also there are a lot of technology to comprise material thickness, cross-section structure, to reach composition etc. in order to adjust the point of release of these elements.For example, PVC(Polyvinylchloride) can cooperate polypropylene and (or) tygon uses, and makes change tensile strength.

The inventor desires to point out at this, also can discharge band and exempted independent power as shown in fig. 1 by in check manufacturing.In the present embodiment, directly the container material on the impression band directly adheres to the directly container material below the impression band, though at least two problems may take place this method.The first and since discharge the required power of each band be give transfer in advance one with the different value of each band connection, so perhaps more easily utilize an independent power releasable material sheet with satisfied control criterion accurately.In addition, an importance of the present invention, though with material discharge with provide can be visual the weight indication, it is not impaired that container itself still need keep.In other words, when container being mentioned and measures its weight, do not have hole or tear of container material.Though on impression band and below material can give and adhere to itself as holistic power releasing member, compare with using independent power releasing member, may cannot say for sure to demonstrate,prove and hole not occur or tear.

Fig. 1 also shows and uses a fillet 28, binds to container near 30, and the strong releasing member of this fillet, and along its length the weight mark of being correlated with is arranged at 32 places.This fillet 28 can use with regard to itself or cooperate said vesse to use, with reference to Fig. 3 and 4 to understand its detailed features.

Fig. 2 A is that a power discharges the front elevation of band before disconnection, and Fig. 2 B shows band owing to the view of mentioning after band adheres to container on it and disconnects, and the weight of container contents is for equaling or exceeding 5 kilograms.Please refer to Fig. 2 A, the band of power releasable material 24 adheres to the material of the container of position on band (18) along dotted line 26, and adheres to the material of the container of position below band (20) along second dotted line 26.Under band 24 was complete situation, the zone 22 of impression gravimetric value kept folding, and hides.Yet, when container is equipped with weight is 5 kilograms or heavier content, and with container when mention at its top, the pulling force that is produced will make band 24 draw back, for to draw back, therefore the weight mark 42 that before is hidden on the material section 22 is exposed in the present embodiment along line of perforation 40.The band of power releasable material will be split into two halves up and down this moment, but by firm than near the material the eyelet along adhering to of dotted line 26, thus mark expose the also unlikely material that undermines container itself.Another kind of mode is, mark can be stamped on the power releasing member that form is band or arrowband, in this situation, surveys the indication band of reading to be kept perfectly, and just can try to achieve gravimetric value.

Fig. 3 A to Fig. 3 C shows another embodiment of power releasable material element.In the present embodiment, power releasable material element comprises a band or arrowband 24, and its front (Fig. 3 A) directly indicates weight mark 42, and center section then is provided with line of perforation 40.The back side (Fig. 3 B) that this power discharges band 24 is attached with mucilage materials 27 along its top and below ora terminalis, and only center section does not contain mucilage materials 28.This band is because tool viscosity directly sticks to container fold (Fig. 1) on the material 22 in its back side of mat.Fig. 3 C shows along the cut-open view of the A-A line intercepting of Fig. 3 B.When the container that includes object when its top is raised, the pulling force that is produced will make band 24 draw back along line of perforation 40, causing the weight of printing on it to indicate 42 can't read, and mat is surveyed the gravimetric value that the complete not impaired band of read bit below impaired band is right after can be tried to achieve content.

In Fig. 4, illustrating a kind of equipment can be in order to the convenient method of making container, and container becomes the form of bag, has the weight indication band of described pattern herein.One mould that is preferably cylindrical section is formed at vertical section 43, one gap 44 is present between these sections, one preferably also is made of networking or other permeable material by the interior element 45 of cylindrical section, and the vacuum that allows to be produced in the mould stretches into interstitial area.Fig. 4 shows the gap that can use for the strong released strip band of institute, because the required power of release band is only set up by releasing member.But, can for for to utilize a kind of mould that many bands are arranged, an associated between each band and the gap is quicken to produce.Continuing please refer to Fig. 4, sheet bag material 46 is placed on the mould 43, is to show this material with section at present embodiment.Utilize the vacuum that is produced in the mould, near the material the gap is pulled in the gap by vacuum, but is stopped by networking wadding 45, produces a succession of in the gathering shown in 47 summaries.Material moves once stable, power releasable material bar 24 can be placed on the aggregate material 47 that contains the relevant mark of impression weight, and put along the line shown in the point 48 and to fix on the location.In addition, can use the means of any adhesion released strip, comprise bonding, pin seam, heat or ultrasonic fusing, comprise spot welding.

Now please refer to Fig. 5, Fig. 5 A shows the alternate embodiment of the present invention of one one-tenth fillet 50 form, and this fillet utilizes recess 52, and all recesses are different sizes, to allow in the difference disconnection along fillet.Fig. 5 B shows that substituting use aperture 54 is used to replace recess, and the size in aperture is in the present embodiment and makes fillet relevant in the required power of particular section disconnection.Shown in two examples in, fillet has a predetermined epimere 60 of being caught and being mentioned by the user, and a hypomere 70 that is attached to container top, but mat bind or provide be attached with fillet container for it.Two structures shown in Fig. 5 also comprise uses vibrations to hold part 86, and the relevant mark of weight has impressed in this and held on the part 86.The vibrations of impression are held part and are utilized various means, comprise bonding, welding etc., adhere to mainly at difference 88 to disconnect fillet.

Can provide as shown in Figure 5, according to fillet of the present invention, but the shockproof part that holds, its mode is for providing long fillet, wherein discharging section effectively arranges with the cut off value incremental order, minimum cut off value is positioned at the top of close fillet, is provided with and holds with a firm grip after sufficient length is provided with and can disconnect interelement at each.Utilize this kind configuration, user at first mat fillet mentions container at its peak, if fillet disconnects, user at first mat fillet mentions container at its peak, if fillet disconnects, the user mentions bag once more with remaining fillet again, and continue so, no longer disconnect up to fillet, use fillet no longer to disconnect, just know that the weight of container contents must can disconnect the impression value that shows on the element less than inferior one this moment.In the present embodiment, the relevant mark of weight will be stamped on the single fillet near power discharges the district.

Though can make the single narrow strip weight indicator of this kind according to the present invention, but necessity repeats to catch and mention the fillet end that is caused when disconnecting, therefore and groundless exempt vibrations and hold part 80, this holds part and can conform with the economized form manufacturing and adhere on main the disconnected fillet.

Fig. 6 shows how to use a kind of fillet with power releasing member of central aperture.User 100 firmly grasps fillet 50 along epimere, and the hypomere of fillet hits knot to by the bag-like container shown in 110 at 104 places.Suppose in the present embodiment, the relevant mark of weight is represented the digital gravimetric value of pound meter, owing to disconnected demonstration-" 5 " marking 114 at 112 eyelet, and a smaller eyelet 116 has disconnected demonstration-" 10 " marking 120, so the content of bag 110 heavily is at least 10 pounds, but is no more than 15 pounds.But, be kept perfectly, therefore cannot see weight in " 15 " shown in 126 at the eyelet 124 of present embodiment minimum.Therefore, the weight of container contents must be less than 15 pounds, but above 10 pounds.

Suppose container improved gradually, and do not limit that the power releasing member will provide the accurate weight readings of container contents by rest position.Under most controlled situation, the accuracy only manufacturing tolerance of stressed releasing member limits; Perhaps, in some cases, be that the profile and the distribution of the content of receptor limits.But, the mode of processing and transfer vessel may cause the hand-power releasing member to produce inaccurate weight indication.For example,,, may cause one or more elements just recommend the momentum of itself if very unexpected or rapidly bag is mentioned no matter where all elements locate in respect to container, particularly with minimum weight all connection person discharge too early.Must with bag when another container is mentioned in such as garbage can another problematic situation appear then.In this situation, the friction force between bag outside surface and garbage can inwall may increase the weight of container and content thereof, the also reading that may lead to errors.

There is the whole bag of tricks can be in order at these inaccurate sources.The most basic preventive measure comprise with power relevant the gain in weight sequential organization all element required with releasing member, the most close lifting of the firmest element source.In this way, must at first overcome the element that correlates with the strongest release force, and, if it is kept perfectly by potential inaccurate source, just may make all elements, comprising that more weak element remains can be according to because the added pulling force of weight of container contents and suitably discharging to making.Another approach increases the release force intensity of all elements for the mat statistical, to take into account unexpected Suo La, friction and other possible inaccurate sources.Implement this method, under the situation that inaccurate source may occur, cooperate preferable container to test all releasing members.According to the data of the extra release strength connection required, according to this all elements are strengthened with accurate result is provided.For example, with the releasing member of 5 pounds note connection, can be designed to actual 5.75 pounds of releases.

Fig. 7 shows another alternate embodiment of weight indicator of releasing member 130 forms, this all releasing member places along a rope 134, the same with above-mentioned fillet, this rope is in order to mention container, to determine the weight of thing in it, the user grips the top 136 of rope, and bottom 138 can be attached to container, or can be used as separate article and bind to container.Though the same with other embodiment of the present invention, power release ring 130 can discharge required weight according to it and form any arrangement, it is preferably with the series arrangement that increases, the most close bottom of minimum release force.This kind arrangement provides maximum likelihood, because discharge at all element series systems, up to first element more energetically that need draw container contents to provide than the gravity rope is provided, but minimum release component is in the bottom, when just lowering container and falling, the momentum that falls by container the possibility of " mistake release " will take place, this is " dead weight " that is different from its content.No matter but the power releasing member is opened band between being, fillet or such as the form of existing described strong endless cable rope is so.

Show that as Fig. 7 four ring-type releasing members 130 are according to impressing in four kinds of weight of all rings itself and with rope 134 releases.Can use various technological adjustment to discharge the required power of rope,, place ring or place the material of the ring of sign " 5 " at ring shown in 140 summaries such as the diameter of ring itself from a ring.In addition, can maybe can put a rivet and pass the axis of this ring, as an alternative the property adjusting gear with the ring flanging so that the power alternative to be provided transverse to its opening.Usually, with described all embodiment are the same herein, as long as can be basic adjustment power by each element, then any releasing mechanism all be fit to and meets the present invention.
