2. Description of the Prior Art
The products of adhesive tapes have been popularized to become the necessities in our lives, and have been being used in the arts of ready-made clothes, general merchandises, and the fields of offices etc.; such as in a bakery, breads are packed with plastic bags, then the mouths of the plastic bags are turned over and are stuck with adhesive tapes. In a market, fruits and vegetables are stacked into cardboard boxes, and then the mouths of the cardboard boxes are fixed by sticking with adhesive tapes. In some cases, adhesive tapes are stuck on a wall or on a floor to mark out working areas or warning areas. Therefore, adhesive tapes are provided for the functions of sticking, packaging, fixing or marking. However, during the process of using, a user often is troubled by cutting the adhesive tapes and deciding the length of cutting, particularly a cutting action is required for every adhesive tape to be taken and a knife or a sharp tool is required for it, if it happens that there is no such an auxiliary tool, cutting of an adhesive tape becomes difficult, and if the adhesive tape is forced to tear up, the breaking area looks very ugly.
Although there have been reel type adhesive tapes which each is placed on the front end of an adhesive tape stand with a cutting device to make convenient of tearing by pulling at any time, the adhesive tape must be pull out and cut on the cutting device in order to take a section of adhesive tape, it is not easy to control the length of every section taken to be equal. Besides, the edges of the adhesive tape are still not adequately neat and in good appearance.
Further, we can see in the markets a kind of alternate type adhesive tape package from which when a user tears a first adhesive tape piece, a second adhesive tape piece therebeneath can be brought up by a sticking force to reveal an end with no adhesive of the second adhesive tape piece for the convenience of tearing by the user. However, the amount of the adhesive tape pieces in designing is not large, this is inconvenient and uneconomic for those shops needing many adhesive tape pieces.
Another kind of conventional adhesive tape set has a prying means and a pressing ring to pick up an adhesive tape piece by rotating the adhesive tape set, so that the user can take the adhesive tape piece. This can solve the problem resided in the former type of adhesive tape package, however, the structure of it is not mature enough, every time when it is to use an adhesive tape piece, the prying means must be pressed to pick up the adhesive tape piece, and the adhesive tape piece can only be torn in the one-way mode, this is cumbersome in operation.
In view of these, the inventor provided the present invention after hard study and development.
The primary object of the present invention is to provide a sequentially stripping-off type adhesive tape set which is in the form of a reel, a user can take the adhesive tape pieces by tearing in a two-way mode after he pries a whole circle of one side of the first layer of adhesive tape pieces, this can avoid the bother of prying the adhesive tape pieces one by one.
The secondary object of the present invention is to provide a divertible seat for the sequentially stripping-off type adhesive tape set in order that the adhesive tape pieces can be more conveniently torn and used.
To achieve the above object, a sequentially stripping-off type adhesive tape set of the present invention is designed to have a sequentially stripping-off type adhesive tape, a holding member and a seat, wherein the seat is mounted thereon with the holding member, while the holding member is provided for placing thereon the sequentially stripping-off type adhesive tape in the form of a reel; the sequentially stripping-off type adhesive tape has thereon many layers of adhesive tape pieces cut in strips wound on a hollow axle cylinder. The front end or the rear end on the bottom surface of each of the adhesive tape pieces is not added with adhesive in order to be used as a tearing area, and the rest portion of it is added with adhesive for sticking to a corresponding one of the adhesive tape pieces of the lower layer, the tearing areas of the mutual neighboring upper and lower layers having no adhesive are arranged alternately in the front-rear direction.
When the adhesive tape is placed in the holding member, a short uncut connecting rim between every two neighboring adhesive tape pieces connects the two without dropping, a tongue of a prying means is used to pry, so that the short connecting rim is broken away to cock the tearing area of an adhesive tape piece, and the user can pull up the tearing area of the adhesive tape piece of the top layer, while the tearing area of an adhesive tape piece of the lower layer is brought out to cock to lap over a protruding annular edge of the holding member, this makes convenient of taking the whole reel of the adhesive tape pieces by tearing in either of two ways.
The present invention will be apparent after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.
Referring firstly to
Moreover, when in cutting the overlapping layers 11 of the sequentially stripping-off type adhesive tape 1, they are broken away at one side, and are left with short uncut connecting rims 123 at the other side. The short uncut connecting rims 123 each has a width of 1 mm, every two neighboring adhesive tape pieces 12 are thereby connected with each other without dropping by having such a short uncut connecting rim 123.
The holding member 3 is an “I” shaped member capable of being detached and assembled, the holding member 3 is formed by connecting of two “T” shaped parts 31 with screw threads 37 respectively on their mutual confronting ends, and a middle cylindrical shank 32 located centrally of the holding member 3 is formed to bear thereon the axle cylinder 2. The middle cylindrical shank 32 is provided thereon with a plurality of mutually spaced protruding annular ribs 36 to reduce the friction against the sequentially stripping-off type adhesive tape 1 when the latter is rotated on the middle cylindrical shank 32 of the holding member 3. The middle cylindrical shank 32 is provided on the outer ends thereof with enlarged end lids 35 to partially hug the two ends of the sequentially stripping-off type adhesive tape 1, and the end lids 35 are provided on the outer sides thereof with two central protruding axles 33.
As shown in
The seat 4 has thereon two arms 41 which include two exposed recesses 411 respectively to allow the two central protruding axles 33 of the holding member 3 to be supported on the two exposed recesses 411 as is shown in
When in application, the sequentially stripping-off type adhesive tape 1 is placed on the holding member 3. It needs only that the adhesive tape 1 is rotated at the first time of use, and meantime a elastic prying means 34 which is slightly raised from the corresponding protruding annular edge 351 is pressed, the tilting tongue 341 of the prying means 34 pries all the tearing areas 121 on one side of the adhesive tape pieces 12 in the first layer of the adhesive tape 1 and has them lapped over the protruding annular edge 351 of the corresponding end lid 35, then the prying means 34 can be released from the adhesive tape 1. It needs only that the tearing areas 121 in the adhesive tape pieces 12 of the first layer are pulled up, then the tearing areas 121 in the adhesive tape pieces 12 of the lower layer can be brought out to cock, and a user can then tear the adhesive tape pieces 12 in either of two ways until the whole roll of adhesive tape 1 is all used.
And more, the seat 4 can have a rotation mechanism, the rotation mechanism includes a protruding post 412 provided beneath the two arms 41 and a base 42 having a socket 421, wherein the inner sidewall of the socket 421 is provided at two mutual opposite positions in a horizontal plane with two dents 422. One side of the protruding post 412 is provided with a protrusion 413, by rotation of the protruding post 412 placed in the socket 421 of the base 42, the protrusion 413 can exactly be engaged in one of the two dents 422 on the inner sidewall of the socket 421. If the protruding post 412 is rotated for 180 degrees, the protrusion 413 will be engaged in the other one of the two dents 422, in this way, the user can adjust the direction at will in operation for the convenience of taking the adhesive tape pieces 12.
Another embodiment of the present invention is shown in
Referring to
The upper disk-like plate 63 and the lower disk-like plate 64 are round disks able to be separated and assembled, a rotation mechanism is provided for these two disks, so that the upper disk-like plate 63 and the lower disk-like plate 64 can be rotated relatively to each other. An embodiment of the rotation mechanism includes an annular rail 70, an annular groove 71, two dents 72 and a protrusion 73; wherein after assembling of the annular rail 70 provided on the upper disk-like plate 63 with the annular groove 71 on the lower disk-like plate 64, the upper disk-like plate 63 and the lower disk-like plate 64 are limited in position and can be rotated relatively to each other. The two dents 72 provided on the upper disk-like plate 63 are respectively provided at two ends of a diameter of a circle 74 which is concentric with the annular rail 70. When the upper disk-like plate 63 is assembled with the lower disk-like plate 64, the protrusion 73 of the lower disk-like plate 64 at a position on the circle 74 can be elastically pressed, and the lower disk-like plate 64 is provided with a recess 65. The notch of the recess 65 has a diameter smaller than that of a round ball 66, the bottom of the round ball 66 is supported by a spring 67, thereby a part of the round ball 66 is exposed out of the surface of the lower disk-like plate 64 and can be elastically pressed. Thereby, when the upper and the lower disk-like plates 63, 64 are assembled with each other and rotated relatively to each other, and when the protrusion 73 arrives at the position of one of the two dents 72, the protrusion 73 and the dent 72 engage with each other, then a force is exerted to rotate the upper disk-like plate 63 to render the protrusion 73 to move downwardly against the elastic force to get rid of the dent 72. After rotating for 180 degrees, the protrusion 73 arrives at the position of the other of the two dents 72 to engage therewith. Thereby, the user can adjust the direction at will in operation for the convenience of taking the adhesive tape pieces 12.
