Description

Technical Field

[0001] This application relates to the field of adhesive tape technology, and more specifically to an environmentally friendly water-soluble adhesive tape. Background Technology

[0002] Adhesive tape is a device used to stick objects together. It includes plastic tape, cloth tape, and water-soluble tape. Plastic tape and cloth tape cannot be dissolved in water. When used to seal ordinary paper packaging containers such as cardboard boxes, the tape is difficult to separate during recycling because it is not water-soluble. The tape itself is also difficult to degrade and easily pollutes the environment. Water-soluble tape, on the other hand, can be completely dissolved or dispersed in water and will not leave any residue that is difficult to remove, thus meeting the current trend of green production.

[0003] An environmentally friendly water-soluble adhesive tape is available, comprising an inner support tube and an adhesive tape. The adhesive tape is wound in a planar spiral around the outside of the inner support tube. In daily use, the user pries up the end of the adhesive tape, cuts it with a cutting device, and then sticks the cut tape to the object to be bonded. However, the newly cut end of the adhesive tape easily adheres to the inner loop of the tape again under the influence of gravity. Furthermore, because the adhesive tape is the same color, the user usually needs to spend time finding the new cut end again, i.e., where the end is located. In situations where multiple applications are required, repeatedly searching for the cut end of the adhesive tape takes a lot of time, affecting the bonding efficiency.

[0004] Therefore, there is a need for an environmentally friendly water-soluble adhesive tape that can more quickly identify the breakage of the adhesive tape. Summary of the Invention

[0005] The main objective of this application is to provide an environmentally friendly water-soluble tape, wherein the environmentally friendly water-soluble tape includes an inner support cylinder with an insertion hole and a removable rod inside the insertion hole; the side wall of the inner support cylinder is wound with an adhesive tape in a planar spiral manner. Before cutting the adhesive tape, the rod can be pulled out and bonded to the vicinity of the pre-cut point of the adhesive tape. The arrangement of the rod allows the user to visually observe the cut end and facilitates the user to tear off the adhesive tape at the cut end. Compared with the prior art, it has the advantage of being able to identify the cut end of the adhesive tape more quickly.

[0006] Another objective of this application is to provide an environmentally friendly water-soluble tape, wherein the two ends of the rod have a reduced diameter portion, and the sidewall of the reduced diameter portion has a plurality of bent ends that can be bent under force, the maximum radial dimension of the bent ends being larger than the diameter of the insertion hole, thereby preventing the rod from detaching from the insertion hole under normal conditions.

[0007] To achieve at least one of the above-mentioned objectives, this application provides an environmentally friendly water-soluble adhesive tape, wherein the environmentally friendly water-soluble adhesive tape comprises: An inner support cylinder has an insertion hole, in which a removable rod is provided; the side wall of the inner support cylinder is wrapped with an adhesive tape in a planar spiral manner.

[0008] In one or more embodiments of this application, the rod has a reduced diameter portion at both ends, and the sidewall of the reduced diameter portion has a plurality of bent ends that can be bent under force, wherein the maximum radial dimension of the bent ends is greater than the diameter of the insertion hole.

[0009] In one or more embodiments of this application, the sidewall of the reduced diameter portion has a plurality of grooves, each groove having a bent end, one end of the bent end extending out of the groove opening at a predetermined distance away from the middle section of the rod, and the other end of the bent end being fixedly connected to the rod.

[0010] In one or more embodiments of this application, the environmentally friendly water-soluble tape further includes two rings, which are slidably fitted onto the two reduced-diameter portions, the bent end has a guiding arc surface, the inner diameter of the ring is equal to the radial dimension of the reduced-diameter portion, and the maximum radial dimension of the ring is equal to the diameter of the insertion hole.

[0011] In one or more embodiments of this application, the end of the rod has an abutment shoulder, the maximum radial dimension of which is equal to the maximum radial dimension of the collar.

[0012] In one or more embodiments of this application, the inner support cylinder has material discharge grooves on both sides, and the material discharge grooves are located at both ends of the rod.

[0013] In one or more embodiments of this application, the inner support cylinder is made of yarn tube paper, and the rod and the collar are both made of plastic.

[0014] In one or more embodiments of this application, the adhesive tape has a raised end at one end, and the raised end is non-adhesive.

[0015] In this embodiment, the environmentally friendly water-soluble tape includes an inner support cylinder with an insertion hole and a removable rod inside the insertion hole. The side wall of the inner support cylinder is wound with an adhesive tape in a planar spiral manner. Before cutting the adhesive tape, the rod can be pulled out and bonded to the vicinity of the pre-cut point of the adhesive tape. The arrangement of the rod will allow the user to visually observe the cut end and facilitate the user to tear off the adhesive tape at the cut end. Compared with the prior art, it has the advantage of being able to identify the cut end of the adhesive tape more quickly. Attached Figure Description

It will also be understood that the terms “comprising” and / or “having” as used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.

[0021] Indicative environmentally friendly water-soluble tape, for reference. Figures 1 to 4 According to a preferred embodiment of the present invention, an environmentally friendly water-soluble tape includes an inner support cylinder 10, the inner support cylinder 10 having an insertion hole 101, and an insertable rod 20 disposed therein; the side wall of the inner support cylinder 10 is provided with an adhesive tape 30 wound in a planar spiral manner.

[0022] It should be noted that by providing the pluggable rod 20 on the inner support cylinder 10, when it is necessary to cut the adhesive tape 30, the rod 20 can be first glued to the predetermined cut point, and then the portion of the adhesive tape 30 located on the rod 20 near the end of the adhesive tape 30 can be cut off by an external cutting device. The newly formed cut end of the adhesive tape 30, i.e., the new end of the adhesive tape 30, is visually observable by the user because the rod 20 is glued to it. Furthermore, since the rod 20 occupies a certain height dimension, the user can more easily lift the new end of the adhesive tape 30. It is evident that, compared to the prior art, this application has the advantage of being able to identify the cut end of the adhesive tape 30 more quickly, and has the advantage of improving efficiency in situations requiring multiple bonding operations.

[0023] Furthermore, to prevent the rod 20 from detaching from the socket 101 when the environmentally friendly water-soluble tape is placed and retrieved under normal conditions, such as... Figure 3 As shown, the rod body 20 has a reduced diameter portion 201 at both ends, and the side wall of the reduced diameter portion 201 has a plurality of bent ends 202 that can be bent under force. The maximum radial dimension of the bent end 202 is greater than the diameter of the insertion hole 101.

[0024] More specifically, in this application, such as Figure 3 As shown, the side wall of the reduced diameter portion 201 has a plurality of grooves 2011, and each groove 2011 has a bent end 202. One end of the bent end 202, which is away from the middle section of the rod body 20, extends out of the groove opening of the groove 2011 by a predetermined distance. The other end of the bent end 202 is fixedly connected to the rod body 20, and the fixed connection method includes, but is not limited to, integral injection molding.

[0025] It should be noted that, under normal circumstances, the axial movement of the rod 20 is restricted by the bent end 202, making it difficult for the rod 20 to dislodge from the insertion hole 101. Furthermore, the length of the rod 20 is less than or equal to the height of the inner support cylinder 10. It should also be noted that when it is necessary to remove the rod 20, the bent end 202 of one end of the rod 20 is inserted into the groove 2011, so that the maximum radial dimension of the rod 20 is less than or equal to the diameter of the insertion hole 101, and it is convenient for the user to pull out the rod 20.

[0026] Furthermore, to enable the bent end 202 to selectively extend out of the groove 2011, as follows: Figure 3As shown, the environmentally friendly water-soluble tape also includes two collars 40, which are slidably fitted onto the two reduced diameter portions 201. The bent end 202 has a guiding arc surface 2021. The inner diameter of the collar 40 is equal to the radial dimension of the reduced diameter portion 201, and the maximum radial dimension of the collar 40 is equal to the diameter of the insertion hole 101.

[0027] It should be noted that when the environmentally friendly water-soluble tape is placed under normal conditions, the rod 20 is placed inside the insertion hole 101, and the collar 40 is located at one end of the groove 2011 near the middle section of the rod 20. At this time, the bent end 202 extends a predetermined distance from the middle section of the rod 20 beyond the opening of the groove 2011. When it is necessary to remove the rod 20, the collar 40 is slid a predetermined distance away from the middle section of the rod 20, and the inner wall of the collar 40 contacts the guide arc surface 2021 of the bent end 202. The bent end 202 is then deformed under force and bent at a predetermined angle towards the bottom wall of the groove 2011 until the bent end 202 is completely placed inside the groove 2011. Since the maximum radial dimension of the collar 40 is equal to the diameter of the insertion hole 101, the rod 20 can be removed at this time.

[0028] Furthermore, to prevent the collar 40 from dislodging from the rod 20 during the extraction process, as follows: Figure 3 As shown, the end of the rod 20 has an abutment shoulder 203, the maximum radial dimension of which is equal to the diameter of the insertion hole 101 and the maximum radial dimension of the collar 40.

[0029] It should be noted that when the user slides the collar 40 and the end face of the collar 40 abuts against the end face of the abutment shoulder 203, the corresponding bent end 202 extends into the groove 2011.

[0030] Furthermore, to facilitate the user in pulling out the rod 20 and sliding the collar 40, such as... Figure 1 and Figure 2 As shown, the inner support cylinder 10 has material discharge grooves 102 on both sides, and the material discharge grooves 102 are located at both ends of the rod body 20.

[0031] In addition, in this application, the inner support cylinder 10 is made of yarn tube paper, and the rod body 20 and the collar 40 are both made of plastic.

[0032] Furthermore, to make it easier for users to locate the end of the adhesive tape 30 of the new environmentally friendly water-soluble tape, such as... Figure 4As shown, the adhesive tape 30 has a lifting end 301 at its end, and the lifting end 301 is non-adhesive. It should be noted that during use, the user can hold the lifting end 301 and gradually lift the adhesive tape 30.

[0033] In summary, the environmentally friendly water-soluble tape described in the embodiments of this application is explained, which provides advantages such as faster identification of adhesive tape breaks.
