Definitions

  • a hand-operated dispenser for adhesive tape comprising a casing adapted for rotatably supporting a roll of adhesive tape, a more or less plane under-surface of the casing adapted to glide over the surface of the article to be taped, an inverted trough-shaped portion on the underside of the casing, located rearwardly with respect to the gliding surface, a slit-shaped opening for the tape in said trough-shaped portion, a bridge piece separating said slit from an opening for the lower end of a movable member adapted with its lower projecting end to impart pressure and a change of direction to the tape, and a knife placed forward of the trough-shaped portion with the knife edge pointing towards but ending above the plane of the under-surface of the case.
  • This invention relates to hand-operated dispensers for adhesive tapes.
  • the invention is concerned with devices of the type having a casing rotatably housing a roll of adhesive tape, a more or less plane under-surface of the casing adapted to glide over the surface of the article to be taped, a tape opening through which the tape issues, a knife on the underside of the casing and a movable member projecting through an opening in the lower surface of the casing and adapted to apply pressure to the tape and act as a guide to change its direction.
  • the movable member is slidably mounted in the casing and capable of assuming two positions. In one lower position of the movable member, the portion of the tape to be cut off by the knife lies below the knife and in the other position above the knife.
  • Such a known dispenser has however a number of disadvantages.
  • the adhesive tape was passed through a slit disposed in a member adapted to impart a change of direction on the tape and next to a pressure roller.
  • the tape could only be made to stick when this member was in its upper position.
  • the drawbacks are most apparent as regards the end of the tape left after the cutting operation. This end was invariably too short, never of the same length and had different shapes. Proper adhesion of the tape thus became a matter of chance. It was practically impossible to pull out the adhseive tape by hand as is sometimes necessary. Moreover, after the cutting operation, the tape became stuck and was thus prevented from slipping back into the casing. The opening of the casing had also such large dimensions that the roll of adhesive tape easily dried out.
  • a handoperated dispenser for adhesive tape comprising a casing adapted for rotatably supporting a roll of adhesive tape, a more or less plane under-surface of the casing adapted to glide over the surface of the article to be taped, an inverted trough-shaped portion on the underside of the casing, located rearwardly with respect to the gliding surface, a slit-shaped opening for the tape in said trough- Patented Jan.
  • the opening through which the tape issues in the trough-shaped portion By arranging the opening through which the tape issues in the trough-shaped portion, the end of the tape left after the cutting operation is solong that it can be readily seized and manually pulled out. The tape, to a large extent, is thus prevented from accidentally sticking to the support or surface on which the dispenser has been placed.
  • the provision of a bridge piece increases the distance between the opening through which the tape issues and the movable member which imparts a change of direction to the tape and thus again increases the length of tape left after this cutting operation.
  • the tape exit slit is narrow and inclined as a result of which the end of the tape is located under the movable member in the proper position for the next sticking operation (application of tape).
  • a further feature of the invention resides in that the tape exit slit is arranged and constructed in such a manner that an imaginary line running from the point where the movable member changes the direction of the tape to the opening of said slit when projected backwards, runs through the central portion of the bearing for the roll of tape.
  • Another feature of the invention resides in that the plane of the upper surface of the slit facing the tape is oriented at an acute angle to the path of the tape between said slit and the lower end of the movable member imparting a change of direction to the tape and the lower surface of the slit is formed by a projecting nose which is offset in relation to the edge of the upper surface at which the tape changes direction. In this way the tape is unrolled with the least trouble and the sticking of the tape end is prevented immediately after the cutting operation. Further the tape end is properly oriented for the next tape application or sticking operation.
  • the roll of adhesive tape is subjected to the action of a suitable braking means such as a resilient tongue or spring mounted on the inside of the casing and the end of the tape is thus prevented from slipping back into the casing.
  • a suitable braking means such as a resilient tongue or spring mounted on the inside of the casing and the end of the tape is thus prevented from slipping back into the casing.
  • the bottom portion of the casing and cover are subjected to undue wear and tear.

  • a centering sleeve (not shown) is formed on the lid 2 and engages in the bearing sleeve 1a.
  • the lower small side wall 117 of the casing 1 which provides the sliding surfaces is formed as an inverted trough 4. Within the trough are located in the direction of the band feed successively the tape exit slit 5, a bridge piece 1b, and an opening 6 for the lower end of a movable member which is adapted to impart a change of direction to the tape.
  • a knife 8 is arranged in a slotshaped bearing formed between a wall portion 10 and a bridge piece 112" limiting the opening 6, the free cutting edge of the knife being downwardly inclined pointing towards the tape as it leaves the casing.
  • the wall portion 1c as well as the knife edge lie above the plane of the small lower side wall 11) of the casing.
  • the movable member 7 is outwardly tilted with respect to the vertical plane at an angle a between 8 and 20.
  • the upper end of the movable member which is adapted to be manually operated, extends through a recess or opening 9 in the front side wall 1d of the casing. This side wall is inclined to the vertical plane at an angle [3 between 10 and 25.
  • the front of the slide is formed with a flattened edge 7a which is engaged by a boss 1c on the edge of opening 9.
  • the movable member or slide 7 is in the form of a hollow body open at one side and has a downwardly projecting bearing portion 7b which is adapted to hold a roller 10.
  • the stub shafts 10a of roller 10 are clamped with a press-fit in recesses 7c and a resilient surface 10b is arranged thereon so that it can be easily turned. Wear and tear of the bearing is thus prevented.
  • the movable member or slide 7 On the side facing the roll of tape 3, the movable member or slide 7 is formed with a ridge 7d which cooperates at its lower end with a projection 1b on the cover and its upper end with edge 9 of opening 9, for the purpose of limiting the sliding movement of the slider 7 at either end.
  • the bottom portion 1 of the casing and the cover 2 are recessed on both sides of the troughshaped portion 4.
  • the edges 1g of the recesses intersect with the roller surface 10b so that part thereof is exposed.
  • the tape exit slit is arranged and oriented in such a manner that an imaginary backward projection 30 of the path 3c of the adhesive tape extending from the contact with roller (when in its lower position) to the exit slit runs through the central area 3d of the bearing sleeve 1a.
  • the upper side 5a of the slit extends from upper edge 5b (at which the tape changes direction) at an acute angle 7 of between 3 and 5 to the path of the adhesive tape.
  • the projecting nose 50 (to which the cut end of the tape is adapted to stick) on the other (lower) side of the slit is displaced downwardly in the direction of travel of the tape with respect to the upper edge 5b. Measured vertically to the path 3c of the tape, the distance a between edge 5b and nose 5c is at most 0.5 mm.
  • the surface of the projecting nose 50 to which the tape is adapted to stick has a maximum width b in the direction of travel of 4 the tape of 0.8 mm.
  • the line A connecting the lower edge 5d of the upper side 5a of the slit (on the side of the slide) and the knife edge extends at an angle 13 (to the horizontal) of at least 25.
  • FIG. 4 shows the manner in which the knife 8 is secured to the :knife bearing formed in the casing 1.
  • the bearing extends between bridge piece 1b" and wall portion 10 (see FIGS. 1 and The rear of the bearing 1h is slightly inclined in its longitudinal direction.
  • the cutting edge 8b when the knife is inserted, although it runs parallel to the back of the knife, is inclined slightly to the path of the tape. Consequently an improved cutting action is obtained.
  • the knife 8 is secured by a boss 1i which engages in a recess 8c in the knife. By means of an additional engagement lj formed between boss 1i and recess the knife is retained in its position also when the cover 2 of the casing has been removed.
  • the tape exit slit 5 by virtue of the provision of the trough can be located in such a manner that only a slight change in direction of the tape and consequently slight friction takes place within the area of the slit.
  • the slit 5 is located comparatively closely to the roll adhesive tape 3, this being of some importance to ensure sticking of the free end of the tape in the area of the slit.
  • the dispenser operates as follows:
  • the dispenser is grasped with the hand and for instance the index finger may apply pressure to the upper end of the movable member or slide 7.
  • the device is now placed onto the article to be taped and during this movement, the roller 10 presses the free end of the tape projecting beyond slit 5 against the surface to which the tape is to be applied.
  • the adhesive tape is then applied to the article by longitudinal movement of the device (see FIG. 3).
  • the movable member or slide 7 is released. This is forced into its upper position (see FIG. 1) by the tension in the tape. In this way, the tape comes into conatct with the cutting edge of the knife and is severed thereby. As a result of an intentional slight clamping action, the movable member or slide 7 remains in this upper position.
  • the tape Whilst it is being directly applied, the tape runs from the roll 3 at an acute angle to line 30' into the slit 5 and continues along line 3c up to the point where it is caused to change direction and moves along the horizontal by the action of roller 10.
  • the tape is thus only subjected to a slight change in direction by the edge 5b, apart from its being re-directed relatively free from friction by the action of roller 10.
  • the edge 5b is so defined that excessive friction is prevented as a result of which adhesion of the free end of the adhesive tape might be prevented at the bebeginning of the direct sticking-on action.
  • vibration is prevented whereby during unrolling of the tape undesired adhesive contact might be caused between the tape and the projecting nose 50.
  • the distance a (between edge 5b and projection 50) is designed to be less than 0.5 mm. and in the case of small, thin tapes is about 0.3 mm. so that the tape after it has been cut off, comes immediately into adhesive contact with projecting nose c and the free end of the tape is held securely in position ready for its next application.
  • the slight vertically off-setting of the edge 5b in relation to the projecting nose 5c as far as adhesion of the free end of the tape on the projecting nose 5C is concerned.
  • the portion of the tape located below the edge 5b, immediately after the cutting action under the action of the tension in the tape and also of edges 5b and 5d is subjected to an angular change in direction towards the left.
  • the ofiset arrangement causes the free end of the tape to be oriented towards roller so that the end of the tape is located beneath roller 10 and is located in the correct position for the next direct application.
  • the edge 5b in imparting a change in direction to the tape straightens the tape and removes from the tape any twist which may have been imparted thereto as a result of it having been wound up on roll 3.
  • the width of the projecting nose 5c is less than 0.8 mm. so that adhesive action of the free end of the tape is just right and the end of the tape becomes immediately detached again from this nose when a new application of the tape is initiated or the tape is manually pulled out from the roll.
  • the angle 6 should be more than 25 otherwise the tape could slide past the edge of the knife without being cut.
  • the angles suggested for the inclination of the movable member or slide 7 and the front small side wall 1d of the casing, are designed to facilitate the function of the device and its manipulation. Below the small side wall 112' two short ribs 1k of slightly less width are arranged. In the event that the free end of the tape should be bent back and come to bear against wall portion 112", the tape would only adhere to ribs 1k and can be easily detached as these ribs do not extend across the full width of this portion of the wall.
  • the glide rails ll, 2l are provided with gliding shoes 11 made from wear resistant material. These shoes 11 may be formed from bent sheet metal or may be sprayed on using a high grade plastics such as nylon. Since the gliding edges broaden out conically in the downward direction (FIG. 6), there is obtained a secure seating for the sides 11a, 11b of the gliding shoes.
