Definitions

  • the present invention relates to dispensing containers and in particular to an improved container, and features thereof and devices therefor, for storing and dispensing a web of material.
  • a web of material such as cling wrap, aluminum foil, paper towel, greaseproof paper, toilet paper and the like are usually sold in rolls.
  • Cling foil, aluminum foil and others are often also sold in disposable cardboard boxes. These cardboard boxes typically include a serrated edge attached to an interior or exterior surface of the box to aid a user to cut a desired length of the web of material.
  • serrated edges used for cutting cling wrap, aluminium foil- or greaseproof paper are often made at minimal cost and are not of a very high quality.
  • the low quality of the serrated edges often infuriates consumers who can find it difficult to cut the wrap into the desired lengths. This often results in more than the desired length being used or to the necessity for repeating the process until the wrap is finally cut.
  • Other products, such as paper towel or toilet paper for example often have perforated sections throughout the web to aid in cutting into desired lengths.
  • some customers, such as mentally disabled or people with arthritis find it difficult to tear off a desired length with ease.
  • the problems associated with the disposable dispensers and low quality serrated edges are enhanced particularly when used for cling wrap.
  • the edges cannot be overly sharp otherwise they may cause inadvertent injury to a user or anyone handling the dispenser.
  • it is difficult to achieve a satisfactory cut with ease on the relatively blunt edges due to the mechanical strength and barrier properties inherent in the cling wrap.
  • the cling wrap has a tendency to fold over and cling to itself due to the polymer additives used in the cling wrap.
  • a further problem with traditional cling wrap containers in particular is the difficulty in locating and picking up the end of the material, particularly cling wrap, from the roll or container. For example, in some traditional cling wrap containers, the cling wrap will fall back onto the roll of wrap inside the container after cutting. It is very difficult for users to then locate and pick up the end of the cling wrap for the next use.
  • cling wrap due to the nature of cling wrap, the wrap will often stick to the front of the container, and for subsequent uses, it is often difficult for a user to locate the leading edge of the cling wrap, especially given that cling wrap is typically transparent, in order to lift the end of the cling wrap from the front of the box. It would therefore be beneficial to provide means to assist location, serving or user pick-up of a web to be dispensed in order to alleviate such problems or associated problems.
  • Disposable cardboard boxes from which cling wrap and the like are typically sold, stored and used are not aesthetically pleasing. They are usually sold in unsightly colours to appeal to consumers at the time of purchase, but are usually kept out of sight in the home.
  • the roll of web material may be disposed directly within the container. Dispensing the web e.g., unrolling cling wrap from the roll creates drag on the roll due to direct contact between the web and the interior of the container. This can lead to poor dispensing characteristics, uneven dispensing, torn web etc. Improvements to alleviate such problems have previously been proposed. These include mounting the roll on a spindle disposed across the entire width of the container. However, whilst such arrangements can improve dispensing characteristics, a spindle alone is not adaptable for various diameters and lengths of roll.
  • the containers include a base and a lid.
  • Each lid includes separate roll cover portions, pivotable mounting for an uppeii pair of jaws and also pivotable mounting for a pair of fingers.
  • Each container includes opposed pairs of pivotable jaws, the upper pair and a lower upwardly spring biased pair of jaws, and also the pair of pivotably mounted cooperating fingers (holding finger and support finger).
  • the fingers are arranged to present therebetween a portion of web to be cut. Pressing down on an upper jaw carrier brings the upper jaws towards the lower jaws. The lower jaws conceal a blade therebetween, the blade being attached to the body of the container.
  • a device for assisting dispensing of web material such as cling wrap, tissue or aluminium foil from a roll
  • the device is simplified in manufacture of parts, assembly process, and in use, in not requiring a separate pivot hinge arrangements, a first pivot for respective pivoting of the lid and base of the container, and a second pivot for separate respective pivoting motion of opposed pairs of jaws for holding the web immediately prior to severing by a spring biased blade as shown in US 5,107,732 and previous WO 88/01972.
  • An alternative dispensing container is disclosed in Japanese patent number 2003175941. This device discloses a roll of material carried on the underside of a lid of the container.
  • the lid includes a push mechanism for exposing a blade.
  • To sever the web requires two handed operation by pushing down on the blade operating mechanism to expose the blade whilst at the same time pulling the web upwardly against the leading edge of the blade.
  • This arrangement has inherent problems. The angle between the blade and the direction the web is pulled does not provide for clean severing, rather, the web may have a tendency to tear or stretch rather than cut clean. Also, pushing down on the lid will expose the blade and risk injury to any person.
  • JP 2004136966 is a further known piece of prior art.
  • This document reveals a dispensing container for roll material.
  • the lid includes a severing blade.
  • the blade is not exposed during severing of the web, because it is disposed in a groove provided in the base, the blade is dangerously exposed when the lid is opened.
  • US patent number 5,161 ,723 is also known prior art.
  • This document discloses an automatic dispenser for roll material, the dispenser having a stationary knife and a cover. The cover pulls on the web of material and thereby drags the material against the knife for severing the web.
  • an apportioning roller Whilst the cover is removed from the knife, an apportioning roller is released to feed a further portion of web forwards for dispensing.
  • a user whilst the cover is removed from the knife for severing the material, a user is either exposed to the sharp edge of the knife and risks injury when receiving the dispensed roll material.
  • a user In order to prevent the dispensed material from falling to the ground, a user must take the material from the dispenser, thereby risking injury as the knife is exposed.
  • a user cannot select any length of material due to the apportioning mechanism, and therefore cannot make a needs based decision as to the required length of material.
  • JP 2004099169 JP 20003276732, JP 2002002714 and JP 11020834.
  • a safety device for a web severing means of a container for dispensing web material including at least one severing means safety cover or guard and at least one safety mechanism which prevents exposure of the severing means with respect to the at least one safety cover or guard until the severing means and web are brought together to at least within a predetermined separation.
  • the severing means is prevented from exposure with respect to the safety cover(s)/guard(s) until the severing means and web are respectively closed sufficiently together.
  • the predetermined closing distance can be selected to be sufficiently small so as to prevent fingers from contact with the severing means.
  • Exposure of the severing means is defined as at least the leading (cutting or severing) edge(s) of the severing means being exposed and does not require the whole severing means to be exposed. It will be appreciated that the severing means may be moved with respect to stationary safety cover(s) or guard(s), or the cover(s) or guard(s) may be moved with respect to stationary severing means, or the severing means and the safety cover(s)/guard(s) may be moved with respect to one another, to expose the edge(s) of the severing means.
  • the safety mechanism may include at least one safety means which restricts exposure of the severing means with respect to the, at least one safety cover or guard until actuated to a release position. More preferably the safety means may be mounted on the at least one safety cover or guard.
  • a single cover/guard and safety means may be provided which can simplify construction and operation, and improve reliability and efficiency of the dispensing container.

  • the at least one release member may be arranged for sliding, rotational and/or pivoting movement to thereby move from a safety position impeding exposure of the severing means with respect to the at least one safety cover or guard to a release position allowing exposure of the at least one severing means with respect to the at least one safety cover or guard.
  • the at least one safety means may be provided on a lid of the container e.g., on or within a severing assembly of the container, and may be operated by contact with a portion of a body of the container on sufficient closing of the lid with respect to the body.
  • operation of the at least one safety cover/guard and/or the severing means is prevented until a gap between the lid and body of the device is closed to at least a predetermined distance.
  • the safety device may prevent exposure of the severing means until the web is held in position for severing, preferably held between at least a portion of the at least one cover or guard and a portion of the body or lid of the container.

  • the cutting assembly and safety device can be carried in the lid or body, or one in each, and the direction of travel can be reversed for an upwardly moving blade, though the principle of operation is the same.
  • the cam is moved to a safety position i.e., to allow the blade to pass once the cam lobe sufficiently contacts a portion of the body. This action compresses the spring and moves the blade blocking portion of the cam out of the path of the blade.
  • Figures 34a to 34d show progressive steps in the operation of the safety device and cutting assembly according to embodiments of the present invention.
  • Figure 36A shows the blade 1700 bounded by two parts 1701a, 1701 b of the safety cover 1701.
  • the blade includes an aperture 1702 through which a cam member 1704 of a safety means projects when in the safety "locked' position.
  • the cover 1701 may also form part of the lid or may be a portion distinct from the lid.
  • the raised front edge 1706 of the container body has a recess therebehind.
  • the lid portion 101a has portion extending forward corresponding to the recess, and a recessed portion corresponding to the raised front edge 1706. This extends substantially the full width of the container. Thus a very small gap is provided between 1701a and 1706 prior to the lid being completely shut. This also provides a convoluted labyrinth type gap acting as an additional safeguard against accidental cut injury. This helps to prevent very small fingers from being cut in that the fingers would be jammed between the lid and body before the blade is sufficiently exposed. The jamming of fingers prevents the safety device from releasing exposure of the blade because the safety release cannot be activated.
  • FIG 34c the lid and cover are completely closed, the safety means cam is retracted clear of impinging the path of the blade.
  • Figure 34d shows the blade moved to a severing position with the tip of the blade 1700 in the severing recess in the body.
  • Figure 35 shows an electrically operated version of the safety device of figures 34a to 34d.
  • Contacts 1720, 1721 n the body and safety cover respectively complete a circuit when the safety cover initially closes to the body.
  • Power from an electrical supply, e.g., battery 1722 causes the safety means 1723 under influence of an electrical coil, motor or magnet, or the like to retract against spring bias.
  • the safety means is thus moved from an aperture in the blade to allow the blade to move.
  • Further actuation of the dispensing container e.g., manually by pressing on the lid or additional electrical actuation, causes the blade to be exposed relative to the cover, which in the embodiment shown is the blade extending out of the cover to sever a web extending across a path of the blade.
  • a switch such as 1725, may be provided. Even if the lid is completely closed for severing i.e., without obstruction, this switch prevents the safety device from releasing the blade until the switch is activated. Thus, an additional degree of safety is provided for over and above the safety device, The switch may be activated by pressure on a portion of the lid relative to the body e.g., downward pressure to activate severing.
