Description

Technical Field

[0001] This utility model belongs to the field of self-adhesive technology, and in particular, it is a residue-free self-adhesive. Background Technology

[0002] In industrial production or daily storage scenarios, opaque storage tanks are widely used. However, such storage tanks have the drawback that the amount of material remaining inside cannot be directly observed. When there are many types of storage tanks, operators may find it difficult to accurately remember the amount of material remaining in each tank. Usually, it is necessary to open the tank lid for manual verification, which is a cumbersome and inefficient process. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a residue-free self-adhesive label.

[0004] The objective of this utility model can be achieved through the following technical solutions: A traceless self-adhesive label includes: a main body, the main body including at least multiple layers, the edges of the multiple layers being fixedly connected, each of the free ends of the multiple layers having a protrusion, the protrusions on each layer being staggered, and each layer having a mark; and a removable adhesive being disposed on the lower surface of each layer.

[0005] The aforementioned residue-free adhesive also includes a bottom layer, with the bottommost layer of the main body bonded to the bottom layer.

[0006] In the above-mentioned residue-free self-adhesive, the area of ​​the bottom layer is larger than that of the main body.

[0007] In the above-mentioned traceless self-adhesive, the multiple layers gradually decrease in size from the bottom layer to the top.

[0008] In the above-mentioned traceless self-adhesive, each layer includes a display part and a protrusion part, the display parts have the same area, and the protrusion parts are connected to the display parts.

[0009] In the above-mentioned traceless self-adhesive, the protrusion may or may not be provided with a removable adhesive.

[0010] In the above-mentioned traceless self-adhesive, each layer of the surface layer has a different color.

[0011] In the above-mentioned residue-free self-adhesive, the surface layer is made of synthetic paper.

[0012] Compared with the prior art, this application has the following advantages: The design features multi-layered staggered protrusions and markings, allowing users to intuitively determine the remaining amount of material inside the tank simply by observing the outer surface layer without opening the lid. This solves the problem of difficulty in confirming the remaining amount in opaque storage tanks, greatly simplifying the verification process. The removable adhesive on the lower surface ensures a good bond and leaves no residue after removal, leaving no residue on the outer wall of the storage tank. The removed main body can also be reused multiple times. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0015] Figure 1 The diagram shown is of the same surface size. Figure 2 The diagram shows different surface sizes.

[0016] like Figures 1 to 2 As shown, a traceless self-adhesive includes: a main body 2, the main body 2 including at least a multi-layered structure 21, the edges of the multi-layered structure 21 being fixedly connected, each free end of the multi-layered structure 21 having a protrusion 211, the protrusions 211 on each layer 21 being staggered, each layer 21 having a mark; and a removable adhesive being provided on the lower surface of each layer 21.

[0017] In this application, the self-adhesive main body 2 is flatly pasted onto the outer wall of the storage tank, ensuring that the protrusions 211 of each surface layer 21 face a direction that is easy to observe, and the bottom layer 3 surface layer 21 is connected to the storage tank. When initially filling with materials, the markings on the outermost surface layer 21 are exposed, for example, the markings indicate that the tank is full. After using a portion, peel off the corresponding outermost layer 21 to reveal the marking on the next layer 21, for example, 75%; peel off the layers 21 above the remaining amount in sequence, and read the approximate remaining amount in the can by the marking on the remaining layer 21.

[0018] The design employs a multi-layered, staggered protrusion 211 combined with markings, allowing for a direct assessment of the remaining material level without opening the can lid. This solves the problem of difficulty in confirming the remaining amount in opaque storage tanks, significantly simplifying the verification process. The removable adhesive on the lower surface provides adhesion without leaving residue, minimizing residue on the outer wall of the storage tank. Furthermore, the detachable main body 2 can be reused multiple times. After use within the storage tank, the entire main body 2 can be peeled off and applied to a new tank.

[0019] Specifically, it also includes a bottom layer 3, on which the bottommost layer of the main body 2 is bonded.

[0020] Specifically, the area of ​​the bottom layer 3 is larger than that of the main body 2.

[0021] This design protects the removable adhesive on the main body 2 from contamination when the self-adhesive is not in use. More specifically, when the main body 2 is attached to the base layer 3, all of it falls into the base layer 3.

[0022] Specifically, the multi-layered layer 21 gradually decreases in size from the bottom layer 3 upwards.

[0023] The area of ​​the surface layer 21 gradually decreases from the bottom layer 3 upwards, so that the protrusions 211 of each surface layer 21 form a clear stepped exposed structure. When the operator tears off the surface layer 21 of the corresponding height, he can accurately grab the protrusions 211 of the target layer. Moreover, even operators who have never used it before can see the layered design of the main body 2 at a glance.

[0024] In another embodiment, each layer 21 includes a display section 212 and a protrusion 211, the display sections 212 having the same area, and the protrusion 211 being connected to the display sections 212.

[0025] Specifically, a removable adhesive may or may not be provided on the protrusion 211.

[0026] When the protrusion 211 is not provided with a removable adhesive, the user can easily pinch the protrusion 211 and tear off the corresponding display part 212.

[0027] Specifically, each of the 21 layers has a different color.

[0028] Different surface layers 21 correspond to different colors, forming a dual "color-height" correspondence with the remaining quantity markings. Operators do not need to check the marking text or scales one by one; they can simply observe the color of the surface layer 21 remaining on the outer wall of the tank.

[0029] For example, the outermost layer 21 is green, the middle layer 21 is blue, and the bottom layer 3 is red. The colors give a general idea of ​​what's left in the jar.

[0030] Specifically, the surface layer 21 is made of synthetic paper.

[0031] Self-adhesive synthetic paper uses resins such as polypropylene (PP) and polyethylene (PE) as the main raw materials. Through extrusion molding, the resin is melted and calendered into a film. Synthetic paper is an existing technology.

[0032] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0033] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Meanwhile, the meaning of "and / or" throughout the text includes three solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0034] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0035] The specific embodiments described herein are merely illustrative examples of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from this utility model or exceeding the scope defined by the appended claims.
