Description

TAPE SUPPLIER Description of the invention This invention is concerned with tape dispensers of the kind used to apply a strip of a coating composition to a surface. The invention is described herein in relation to so-called correction tape spouts, which are used to lay on a paper surface a layer of thin material to cover a typing or typing error and from here they facilitate the correction of that error. However, the tape dispensers described here could be used to apply other Coating layers to a surface The tape dispensers have an applicator tip that defines a border around which the tape passes and which is used to press the tape against the paper surface. The tape consists of a reinforcing tape, for example from paper or plastic, which carries or carries on one side a continuous layer of the coating composition When the tape is pressed against the paper surface by the applicator edge and the edge is caused to move on the fresh surface tape, it is removed from a supply of tape contained within a spout body, as the tape passes. around the edge of the coating composition is transferred from the support tape to the paper surface, such that a continuous strip of the composition is deposited on the paper and the spent tape from which the coating composition has separated it is removed back to the dispenser body for storage until the entire supply of the tape has been consumed when the used tape or possibly the entire dispenser is discarded. The dispenser body forms a handle by means of which the dispenser is attached to the dispenser. hand by the user REF: 27063 Due to its global shapes and configurations, many correction tape dispensers are annoying to retain during use. In the prior art patent application number GB2275042 a tape dispenser with a tape guide arrangement is disclosed which allows the spout handle to be oriented relative to the edge of the applicator, such that the handle can be retained in use in a manner similar to the manner in which a writing instrument is retained. Thus, in use, the spout handle may extend up the paper in a generally inclined direction toward the user. This configuration makes the dispenser convenient and easy to use, but has a disadvantage in that it is "dependent on the right hand or the left hand", which means that a dispenser proposed to be used as long as it is retained in the right hand it can not be easily used as long as it is held in the left hand. The present invention addresses this problem and as a solution provides a tape dispenser comprising a handle, within which there are means for storing a supply of tape consisting of a support tape carrying a coating composition and a carrier tape. wherein the coating composition has been separated, an applicator with an edge around which the tape passes and arranged to press the tape against a surface to transfer the coating composition from the support tape to the surface, the handle is coupled to the surface. applicator to allow selective adjustment of the handle relative to the edge of the applicator between inclined positions in opposite directions with respect to a plane normal to the edge. More conveniently, the handle is rotatably adjustable in relation to the applicator between the positions which are most suitable for use of the left hand and the right hand. A retention mechanism can be provided to retain the handle in the selected adjustment position during normal use, in such a way that the user is not required to perform special stages, such as squeezing any part to secure the position of the handle In a presently preferred embodiment, the retention mechanism is in the general form of a ratchet that allows the handle to be adjusted to any vain positions. In addition to allowing the spout to be configured for easy use by the left hand or the right hand, this has the advantage to allow the user to select a range of inclinations of the handle, according to personal preference in terms of convenience and comfort in use Because the handle is adjustable, the areas from which the tape is fed to the applicator and to which the worn support tape supplied from the applicator are not predetermined. The tape guide means are preferably arranged to guide the tape through a position substantially coincident with the axis around which the handle is adjustable relative to the applicator. In this way, the tape can be guided between the edge of the applicator and a position which is fixed relative thereto without regard to the adjusted position of the handle Conveniently, the belt guiding means comprise a pair of cylindrical rollers with their rotational axes parallel to the pivot axis and their spaced apart surfaces spaced sufficiently to allow the belt to run freely between them A complete understanding will be obtained of the invention from the following detailed description of an exemplary embodiment, reference is made to the accompanying drawings, in which: Figure 1 is an exploded perspective view of a correction tape dispenser according to the invention; Figure 2 is a schematic side view with the cover of the separate handle box; Figure 3 illustrates the jet set for use with the right hand; and Figure 4 illustrates the jet set for use with the left hand. The illustrated ribbon dispenser comprises a body or hand 1 including a box mounted from a base part 2 and a cover 3, secured together by fasteners, welding or by any other convenient means. Mounted within the box are a pair of transverse spindles 4, 5 supported between the base and the cover and carrying respectively a supply reel 6 and a winding reel 7. The reels include integral pulleys around which a band 8 of continuous drive is driven, such that as a new correction tape is removed from the supply spool 6, the winding spool 7 is rotated to wind the used support tape. Between the two reels, a section of tape is guided to pass out of the box, around an operative edge 10 of an applicator 12, which projects from the box and back into the box. The applicator has an arm 13 that bears a tip 11, which defines an edge 10 and the tip can be fixed on the arm or movably mounted thereto to facilitate the application of the correction composition to a surface, by example as described in patent application PCT / US94 / 06585. The inner end of the arm carries partially cylindrical cover bearing elements 14, which are arranged to articulate in circular recesses or recesses provided on the inner surfaces of the base and the cover of the box, such that the applicator and the Handles are relatively rotating. The confronting faces of the rolling elements and the hollows or recesses of articulation of the box are formed with complementary detents, such as a series of projections around one face and a series of depressions around the other face, to form a system of ratchet that allows the applicator 12 to be adjusted to any of several positions between two extreme rotary positions, which are defined by the edges of the opening of the box through which the arm 13 of the applicator projects. As best seen in Figure 2, the handle is adjustable to extend in opposite inclined directions in relation to a plane P normal to the edge 10. Ported on each side of the applicator arm, within the confines of the bearing elements, are a pair of rotary guide rollers 16, 17 which are located opposite each other with respect to the pivot axis of the box 1 and the applicator 12. The roller surfaces are spaced a small distance apart to allow the tape to run freely between them. Thus, of the supply reel, the belt 18 consisting of the support belt and the correction composition passes through a position coinciding with the pivot axis and defined by the pair of guide rollers 16, 17 on one side of the arm The applicator passes to and around the edge 10 of the tip 11 of the applicator, passes back to a position coincident with the pivot axis and defined by the pair of guide rollers 16, 17 on the other side of the applicator arm and then passes to the applicator arm. 7 winding reel. During use, the spout is held by the box or handle, the edge 10 of the tip of the applicator is used to press the tape 18 against the paper surface and the edge is caused to move across the surface in one direction substantially perpendicular to the edge. The correction composition is transferred from the support tape to the paper surface, as the tip causes the new tape removed from the supply reel 6 and the support tape 18 'to move. after having passed around the edge of the tip and therefore without the correction composition (separated from the support tape), it is wound on the winding reel 7. In this way, the correction composition is applied to the paper surfaces as a continuous strip 19 (figures 3 and 4). The articulated or rotating adjustment, enabled between the applicator 12 and the handle 1, allows the handle to be easily adjusted from a position that facilitates use for a right-handed person, as shown in Figure 3, to a position that facilitates the use for a left-handed person, as shown in figure 4.

In addition, due to the ratchet system, the angle at which the handle needs to be held in relation to the paper can be adjusted for maximum comfort by right-handed and left-handed people. It will be appreciated that modifications to the described tape dispenser are possible without departing from the concept of the invention. For example, it can be mentioned that low friction guide pins could be used instead of the guide rollers 16, 17. Also, the rotatable adjustment between the handle and the applicator can allow the selection of only a few positions with the movable tape 11 to provide more precise adjustments of the position of the handle during use.

It is noted that, in relation to this date, the best method known by the applicant to carry out the aforementioned invention is the conventional one for the manufacture of the objects to which it relates. Having described the invention as above, property is claimed as contained in the following
