Definitions

  • This type of reel container includes first and second complementary case or container sections.
  • One of the container sections defines a locking surface and the other of the container sections carries a movable detent engageable with the locking surface to draw the peripheries of the container into sealing engagement to thereby form a tight enclosure for the reel, More particularly, the detent is carnmed radially outwardly into engagement with an inclined or arcuate locking surface, and as the detent is forced further radially outwardly, the two container sections are drawn tightly together.
  • the detent is a relatively hard noncompressible element which is not subject to cold fiow when subjected to compressive forces.
  • each of the container sections is constructed of molded plastic material. It is inherent in molding the container sections of plastic material, that the container sections will tend to assume a generally convex shape, i.e., tend to bow outwardly at the central regions thereof. As the locking surface and the detent are carried by central portions of the container sections, such inherent bowing tends to elevate the detent relative to the locking surface. It is not uncommon for this convexity to be sufiicient to prevent engagement or proper engagement of the detent and the locking surface.
  • the present invention over-comes the problem of the inherent tendency of the container sections to bow outwardly and allows construction of the container sections within wider tolerances.
  • the present invention teaches that this result can be accomplished by initially positioning the detent in the unlocked position thereof, radially inwardly and below, i.e., axially spaced from, the locking surface.
  • the words above, below and similar words relating to elevation have reference to axial spacing, it being understood that reel containers of this type can be easily manually inverted or turned to various other orientations. T o interlock the container sections, the detent is first moved radially outwardly and then axially upwardly to forcibly engage the locking surface and thereby draw the container sections together into tight sealing relationship.
  • the detent is initially at an axial position which is lower than with the prior art device.
  • the detent engages the locking surface and applies a force thereto which draws the container sections tightly together.
  • the plastic of the container section against which the detent bears has suificient resilience to resiliently deform under the force of the detent Without causing damage to the container section.
  • first and second complementary container sections engageable to form a substantially dust-tight enclosure
  • means on the first container section defining a locking surface at a central portion of the container section
  • means on the second container section for mounting a detent for radial and axial movement toward and away from the locking surface.
  • a movable actuator is provided for moving the detent radially and axially into engagement with the locking surface.
  • Another feature of the present invention is to facilitate the manual locking movement that the user causes the actuator to undergo. This is accomplished by positioning the detent and the locking surface so that a substantial portion of the radial movement of the detent occurs without any forcible engagement between the detent and the locking surface. Thus, for this portion of the detent movement, the actuator is very easily movable and it is only for the latter portion of the actuator movement that any significant force must be applied to the actuator.
  • the axial movement of the detent is obtained through a camming action.
  • the detent may ride on a camming surface which is mounted for movement with and forms a portion of the actuator.
  • the caniming surface includes a ramp portion which serves to elevate or move the ball axially from its lower position to its upper locking position.
  • the detent is in the form of a ball which rolls easily as it is urged along by the cam.
  • the actuator includes a handle portion which is rotatably mounted on one of the container sections, preferably the upper container section.
  • the upper container section is provided with rigid abutments and the handle has stop members engageable with the abutments for limiting the arc of rotation of the handle.
  • the abutments and stop members are strong and not subject to shearing off or otherwise failing during normal use of the container.
  • Another feature of this invention is the manner in which the locked position of the container sections is marked.
  • One of the container sections preferably the upper container section has a shallow recess and the handle is formed with a projection receivable in the recess when the handle is turned to the locked position.
  • the handle is preloaded downwardly against the container section by the action of the cam in forcing the detent upwardly against the locking surface.
  • the projection is therefore caused to enter the groove with a type of positive snap action.
  • the projection and recess may be reversed, if desired, with the projection being formed on the container section and the recess formed in the handle.
  • FIG. 1 is a top plan view of a reel container constructed in accordance with the teachings of this invention.
  • FIG. 2 is an enlarged sectional View taken along line 2-2 of FIG. 1 and showing the detents or locking balls in their locking position.
  • FIG. 3 is a perspective view of the ball retainer which imparts axial movement to the detents.
  • FIG. 4 is a sectional view taken along line 44 of FIG. 2 and showingthe components of the device in the locked position.
  • FIG. 5 is a sectional view similar to FIG. 4 showing the detents in the releasing position.
  • FIG. 6 is a fragmentary sectional view taken along line 66 of FIG. 5 and showing the relationship of the detents and the locking surface in the releasing position.
  • FIG. 7 is a fragmentary sectional view taken along line 77 of FIG. 4 showing the means for limiting rotation of the handle unit and for advising the user when the case is in the locked position.
  • FIG. 8 is a'fragmentaryview taken from the top of FIG. '7.”
  • reference numeral 11 designates a reel container constructed in accordance with the teachings of this invention.
  • the reel container 11 generally includes an upper case or container section 13 and a lower container or case section 15 both of which are constructed of suitable molded plastic material.
  • the lower container section 15 includes a bottom wall 17, a centrally disposed cylindrical wall section 19, which projects axially inwardly into the container 11, and a transverse end wall 21 generally parallel to the bottom wall 17 and having an axial aperture therethrough.
  • a pair of upstanding peripheral webs 23 and 25 extend completely around the periphery of the lower container section 15 and form a retainer for an O-ring 27.
  • the transverse end wall 21 terminates radially inwardly in an inclined annular surface which defines a locking surface 29.
  • the locking surface 29 is frustoconical and therefore appears flat in radial cross section.
  • the upper container section 13 includes a top wall 3-1 and a generally cylindrical peripheral wall 33, the lower end of which is received between the webs 23 and 25 and sealingly engages the O-ring 27. Both the bottom walls 17 and top wall 31 are provided with suitable reinforcing ribs such as radially extending ribs 35.
  • the upper container section 13 also includes a cylindrical wall 37 generally coaxial with the cylindrical wall section 19, a transverse end wall 39 confronting and closely adjacent the transverse end wall 21, and an axially extending generally annular flange 41 (FIGS. 4 and 5) extending axially from the transverse end Wall 39 through the aperture in the transverse end wall 21.
  • the cylindrical wall 37 and the transverse end wall 39' form a centrally disposed well which extends into the reel container 11. As shown in FIGS. 4 and 5, the annular flange 41 has openings 43 therein, each of which contains a detent in the form of a locking ball 45.
  • the upper container seetion 13- and the lower container section 15 can be assembled as shown in FIG. 2 to form a sealed container for a reel 46 of tape or for other products.
  • the reel 46 is annular so that the cylindrical wall section 19 and the cylindrical wall 37 are received within the opening of the annular reel.
  • the reel 46 is held tightly within the container 11 by a pair of resilient rings 46a which fit over the walls 19 and 37 and grip the inner edges of the reel.
  • a handle unit 47 and a cap 49 combine to form a rotatable actuator for imparting the desired movement to the balls 45.
  • the handle unit 47 includes a cup section 51 rotatable in the well defined by the cylindrical wall 37 in the transverse end wall 39, a handle 53 within the cup section and afiixed thereto, and a cam section 55 integral with the cup section and slidingly received within the annular flange 41.
  • the handle unit 47 is mounted on the reel container by the cap 49 which is suitably aflixed thereto as by a key (not shown) and an adhesive.
  • the cam section 55 has a generally cylindrical periphery as shown in FIGS. 4 and 5 with portions thereof cut away to form recesses 57 to permit radial inward movement of the balls 45.
  • the remainder of the peripheral surface or the curved portions thereof are operative to urge the balls 45 radially outwardly.
  • the number of the recesses 57 corresponds to the number of locking balls 45 so that by rotation of the handle unit 47, the balls 45 can be cammed radially outwardly to a locking position, and by counterrotation of the handle unit, the balls 45 are allowed to retract radially inwardly into the recesses 57 to a releasing position.
  • the balls 45 when the balls 45 are urged radially outwardly they contact the inclined locking surface 29 to draw the two container sections 13 and 15 tightly axially together to form a substantially dust-tight enclosure.
  • the peripheral wall 33 is caused to bear tightly against the O-ring 27 to thereby form a tight seal around the periphery of the reel container 11.
  • the cap 49 which is shown most clearly in FIG. 3, includes an upstanding ring portion 59 and a base portion 61.
  • the ring portion 59 has a keyway 63 therein to allow the cap 49 to be keyed to the cam section 55 of the handle unit 47.
  • the base portion 61 serves to support the balls from below as shown in FIG. 2.
  • the base portion forms a cam for each of the balls 45 to urge such balls axially.
  • Each of such cams includes an elevated portion 65 and a recessed portion 67 interconnected by an inclined ramp portion 69.
  • the cap 49 is rotatable with the handle unit 47 so that the ramp portion 69 eventually comes beneath the ball 45 and depending upon the direction of rotation, the ramp portion moves the ball upwardly to the elevated portion 65 or allows the ball to be lowered into the recessed portion 67.
  • the balls 67 are elevated by the ramp portion 69 to urge the balls tightly axially against the locking surface 29 to assure that the reel container is tightly sealed.
  • each of the recesses 57 begins substantially at the intersection of a ramp 69 and a recessed portion 67 and extends circumferentially beyond the other end of such recessed portion and terminates along the adjacent elevated portion 65.
  • the balls 45 are resting on the recessed portions 67 and are disposed radially inwardly in the recesses 57 so that the balls are spaced from the locking surface 29 (FIG. 6).
  • the balls 45 are cammed radially outwardly by the cam section to the maximum radial outward positions thereof in which they engage or nearly engage the locking surface 29. At this point the balls 45 are resting on the recessed portions 67 and about to move up their respective ramp portions 69. This position of the balls 45 may be referred to as the intermediate position.
  • the handle unit 47 is rotated further in the same direction so that the ramps 69 come beneath the balls 45 to urge the latter axially upwardly onto the elevated portions 65 and into tight engagement with the locking surface 29 to thereby draw the two container sections 13 and 15 tightly together. Further, during the elevation of the balls, they are held in their radial outward position by the curved portions of the cam section 55. To unlock the reel container 11, the handle unit 47 is counterrotated, whereupon the balls 45 are first moved axially away from the locking surface 29 as permitted by the ramp portion 69 and then they are allowed to move radially inwardly by the recesses 57 upon further counterrotation of the handle unit.
  • the balls 45 are recessed or lowered by the recessed portions 67 so that under no circumstances would the balls 45 initially be too high up relative to the locking surface 29' to lockingly interengage therewith. As the balls 45 are moved both radially and axially toward the locking surface 29,
  • the container sections 13 and 15 are locked securely together. It is preferred in the moving from the releasing position to the locking position to initially move the locking balls 45 only radially and not axially to the intermediate position. Normally the portion of rotation of the handle unit 47 which moves the balls 45 radially outwardly is accomplished very easily as normally the balls do not contact the locking surface 29 until they reach or nearly reach the maximum radial outward positions thereof.
  • the size and orientation of the recesses 5-7 relative to the portions 65, 67, and 69 can be changed depending upon the results desired.
  • these portions of the device are arranged so that in moving from the releasing to the locking positions, the balls first move only or substantially radially and then move only or substantially axially.
  • the handle unit 47 carries at least one stop member 71 on the periphery of the cup section 51 as shown in FIG. 7.
  • a suitable abutment 73 is molded integrally with the upper container section 13 integral with the cylindrical wall 37 and projecting radially inwardly as shown in FIGS. 7 and 8. At least two of the abutments 73 are provided so that rotation of the handle unit in both directions is limited and in the embodiment illustrated, two pairs of the abutments 73 are provided.
  • the abutments 73 are appropriately spaced so that when the stop members 71 contact one of the abutments, the reel container is in the locked position and when the other of the abutments is contacted, the container is in the releasing position.
  • Another feature of this invention is the manner in which the locking and releasing positions are marked. It is apparent that when the reel container 11 is in or near the locked position, that the balls 45 urge the handle unit 47 downwardly tightly against the transverse end wall 39.
  • the transverse end wall 39 is provided with a shallow recess 75 (FIG. 7) immediately adjacent each of the abutments 73.
  • the stop member 71 engages the abutment 73
  • the lower end of the stop member 71 which forms a slight downward projection, is pulled into the recess 75 to produce a sort of clicking or snap action noticeable to the operator.
  • the operator is advised that the fully locked position has been reached and there is no danger of leaving the reel container only partially locked.
  • the stop member engaging in the recess 75 provides some additional resistance to unintentional counterrotation of the handle unit 47. Therefore, it is less likely that the reel container will unintentionally become unlocked.
