[0001] This utility model relates to a chemical casting and daily necessities, and more particularly to a disposable foldable chemical paper funnel, used for casting adhesive for steel wire rope joints, chemical dispensing, and dispensing of daily necessities. Background Technology

[0002] Wire rope cast-in-place joints are widely used in various applications requiring high-strength connections, such as the transportation of high-strength ropes for hoisting and hauling. During use, it is crucial to pay attention to the ratio of the hook or the suspended object to the wire rope diameter, as well as the degree of surface wear and corrosion, and the number of broken wires per twist pitch, to ensure safe operation. The main functions of wire rope cast-in-place joints include enhancing joint strength, improving wear resistance, and corrosion resistance. Specifically, the casting process firmly bonds the wire rope to the joint, ensuring that the joint does not delaminate under dynamic tension and bending, thereby significantly improving the joint's strength and durability.

[0003] Currently, in the process of casting steel wire rope joints, funnels are commonly used as the carrier for adhesive pouring to improve the smoothness of adhesive pouring. The existing funnels are mostly made of stainless steel, plastic or glass and are of immutable shape. They not only take up a lot of space and are not conducive to packaging and carrying, but also have high manufacturing and usage costs. They need to be cleaned and wiped clean after use, which is time-consuming and laborious. In addition, because the steel wire rope joint is an open joint, the adhesive pouring cannot be balanced and is prone to dripping. Utility Model Content

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] In some embodiments, this addresses the problems of traditional funnels being space-consuming, inconvenient to package and carry, and costly to use, as well as the poor balance and easy leakage of steel wire rope adhesive during pouring. For example... Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a disposable foldable chemical paper funnel is provided, which includes a folding body 100. The folding body 100 includes a plurality of cone-shaped units 101 connected in sequence and a connecting strip 102 located on at least one side, and is integrally cut from coated paper. This technology forms a folding body 100 containing cone-shaped units 101 and connecting strip 102 by integrally cutting coated paper, so that the overall initial shape is a flat structure, which greatly reduces the space occupied for packaging and transportation.

[0036] Specifically, an adhesive layer 200 is provided on the connecting strip 102. Several vertebral units 101 are folded end to end and connected together, and then bonded and fixed by the adhesive layer 200 to form a rhomboid vertebral funnel with a larger upper end and a smaller lower end. In other words, the funnel body is formed by several vertebral units 101 being folded end to end and connected together, and then quickly fixed by the adhesive layer 200 on the connecting strip 102, without the need for complicated assembly tools.

[0037] The resulting funnel has a rhomboid cone structure, which enhances the balance of casting through polygonal prismatic supports, avoiding glue deviation and leakage caused by uneven force distribution at a single point in traditional circular funnels. Using coated paper as the manufacturing material ensures both the funnel's liquid barrier performance and meets the requirement of being disposable after single use, eliminating the burden of cleaning and maintenance associated with traditional metal or plastic funnels.

[0038] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in order to solve the problem of unstable funnel fixation caused by the lack of auxiliary grip structure at the top of the folding body, the folding body 100 also includes an ear plate 103. By setting an integrally formed ear plate 103 at the top of the cone unit 100, an extension structure that can be gripped can be provided for the folded funnel.

[0039] Specifically, the ear plate 103 is disposed on the top of one of the cone-shaped units 101, and is integrally cut from the coated paper together with the cone-shaped unit 101 and the connecting strip 102. The ear plate 103, the cone-shaped unit 101, and the connecting strip 102 are integrally cut from the same coated paper material, which not only ensures the uniformity of structural strength, but also avoids additional assembly processes.

[0040] The design of the ear plate 103 located at the top edge of the cone unit 101 allows users to achieve precise control when pouring liquids by pinching the ear plate 103, effectively preventing deformation or slippage caused by direct contact of the funnel body with the hand. The one-piece cutting process also makes the ear plate 103 and the funnel body form a continuous planar structure, maintaining the flatness of the overall sheet material before folding, and naturally forming a three-dimensional auxiliary structure after folding.

[0041] In some of these embodiments, such as Figure 3 and Figure 4 As shown, the coated paper uses ordinary paper or ordinary kraft paper as the base layer, and a coating layer is applied to the upper surface of the base layer. This coated paper is commercially available. Using ordinary paper or kraft paper as the base layer retains the lightweight and foldable characteristics of paper, while the choice of kraft paper enhances the mechanical strength of the base layer. The design of coating the upper surface of the base layer with a coating layer effectively improves the material's impermeability by forming a continuous and dense polymer film on the paper surface, ensuring that liquids such as adhesives do not leak during the casting process.

[0042] The lower surface of the coated paper is printed with LOGO information 104, which is presented on the outer side of the rhomboid cone funnel after folding. The LOGO information 104 can be information such as the size of the funnel or the manufacturer's information, which serves as a product identifier and ensures the clear visibility of the product identifier.

[0043] In some embodiments, the cone units 101 are four, five, or six, thereby folding to form an equilateral quadrilateral, pentagonal, or hexagonal funnel structure. By limiting the number of cone units 101 to four, five, or six, the folded funnel structure can form an equilateral quadrilateral, pentagonal, or hexagonal geometry.

[0044] The choice of the number of cone-shaped units 101 directly affects the number of edges and the overall symmetry of the funnel: for example Figure 3 and Figure 4 The quadrilateral structure shown ensures stability while maximizing material utilization; the pentagonal or hexagonal structures improve the uniformity of sidewall support by increasing the number of edges, thereby optimizing the balance during adhesive pouring. The equilateral design ensures consistent stress distribution across all edges, preventing structural deformation or material leakage caused by localized stress concentration. Structures with different numbers of edges can accommodate different diameter wire rope joints or adhesive flow characteristics, enhancing versatility and improving leak-proof performance through geometric symmetry.

[0045] In some of these embodiments, such as Figure 1 and Figure 2 As shown, to reduce glue dripping and improve operational convenience, the structural stability and casting balance of the folded funnel are optimized through specific dimensional design. The top edge a of the cone unit 101 is designed to be 70mm, the bottom edge b to be 15mm, and the height c to be 180-200mm. This technical solution achieves precise control over the shape of the folded funnel by limiting the specific geometric parameters of the cone unit.

[0046] Specifically, the top edge 'a' is set at 70mm to ensure the funnel inlet has sufficient width to accommodate the glue pouring requirements, while preventing the structure from becoming loose due to an excessively large opening; the bottom edge 'b' is set at 15mm to ensure the outlet is narrow and concentrated, effectively reducing dripping during glue flow; the height 'c' is set in the range of 180-200mm, providing sufficient glue flow path length to balance pouring pressure, while also preventing the funnel's support capacity from decreasing due to insufficient height. Through the coordination of these three elements, the folded rhomboid cone funnel ensures structural stability while also guaranteeing smooth pouring and leak-proof performance.

[0047] As a preferred embodiment, to address the problem of unstable installation and easy interference with material leakage caused by insufficient compatibility between the funnel reinforcing ribs and the rhomboid cone funnel structure, such as... Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the disposable foldable chemical paper funnel also includes a fastening paper body 300 integrally cut and disposed on the top edge of the folding body 100.

[0048] Specifically, an easy-tear line 303 is provided between the fastening paper body 300 and the folding body 100. The fastening paper body 300 is integrally cut out from the top edge of the folding body 100, and the easy-tear line 303 is used to achieve convenient separation between the fastening paper body and the folding body.

[0049] In use, after the fastening paper body 300 is torn apart from the folded body 100, the connecting layer 400 is folded and bonded end to end to form a funnel reinforcing rib that can be fitted onto the upper outer periphery of the rhomboid cone funnel. That is, the separated fastening paper body 300 forms a ring-shaped reinforcing rib structure by folding and bonding end to end. After being fitted onto the upper outer periphery of the funnel, it can effectively enhance the radial deformation resistance of the funnel body during glue pouring.

[0050] The design of the easy-tear line 300 ensures efficient integrated cutting during production and enables quick separation of the reinforcing rib assembly during use. Positioning the reinforcing rib on the upper outer periphery of the funnel not only strengthens the most easily deformable area of ​​the funnel but also avoids affecting the pouring operation space of the upper port diameter of the funnel. The bonding and fixing method of the connecting layer 400 makes the reinforcing rib removable and reusable, taking into account both structural strength and usage flexibility.

[0051] In some of these embodiments, such as Figure 5 , Figure 6 , Figure 11 and Figure 12 As shown, the fastening paper body 300 includes a plurality of fastening units 301 connected in sequence and an adhesive portion 302 located on at least one side. The plurality of fastening units 301 and the adhesive portion 302 are respectively disposed at the top edge positions of the plurality of cone units 101 and the connecting strip 102 via the tear line 303. By correspondingly disposing the fastening units 301 and adhesive portion 302 of the fastening paper body 100 with the cone units 101 and connecting strip 102 of the folding body, the two form an integrated structure when the folding body is unfolded.

[0052] The correspondence between the fastening unit 301 and the top edge of the cone unit 101 ensures that the fastening paper 300 can accurately match the contour of the rhomboid cone funnel formed by folding the folding body 100 after the easy-tear line 303 is torn off, thus preventing misalignment during the installation of the reinforcing ribs. The corresponding setting between the adhesive part 302 and the top edge of the connecting strip 102 ensures that the beginning and end of the reinforcing ribs coincide with the fixing points of the connecting strip 102 on the folding body 100 when they are bonded, enhancing the overall structural connection strength. Through the above design, the technical effect of pre-installing the reinforcing rib assembly in the flat state and quickly peeling and installing it during use is achieved, simplifying the operation process while improving the supporting effect of the reinforcing ribs on the funnel.

[0053] Furthermore, to address the issue of loose bonding caused by interference from the angular structure when fastening the paper body through 300-degree folds to form the funnel-shaped reinforcing ribs, and to avoid stress concentration or structural deformation after the reinforcing ribs are installed, such as... Figure 5 , Figure 6 , Figure 9 , Figure 10 , Figure 11 and Figure 12As shown, clearance holes 304 are respectively provided between several of the cone-shaped units 101 and the connecting strip 102 near the tear line 303 to form clearance gaps at the corners of the funnel-shaped reinforcing ribs. This technical solution, by providing clearance holes 304 at specific positions between the cone-shaped units 101 or in the connection area between them and the connecting strip 102, creates structural clearance space at the corners of the funnel-shaped reinforcing ribs formed by tearing and folding the fastening paper body 300.

[0054] Specifically, the clearance hole 304 is located near the tear line, which corresponds to the stress concentration area at the angle of the reinforcing rib after folding. By removing the clearance notch formed by cutting off some material, the interference caused by material stacking during the folding process can be eliminated, allowing the reinforcing rib to fit tightly against the outer contour of the funnel body. This design ensures both the circumferential constraint force of the reinforcing rib on the funnel body and avoids the mutual pressure of rigid structures at the turning point, maintaining the overall geometric stability of the funnel.

[0055] In some of these embodiments, such as Figure 9 and Figure 10 As shown, the funnel reinforcing rib, formed by folding the fastening paper body 300, is detachably fitted onto the outer periphery of the upper part of the rhomboid cone funnel using an inverted fastening method, and the clearance notch at the top corner corresponds one-to-one with the hypotenuse of the rhomboid cone funnel. This technical solution achieves a precise fit between the reinforcing rib and the funnel body through the inverted fastening method and the spatial adaptation design of the clearance notch.

[0056] Specifically, the inverted buckle design allows the reinforcing ribs to naturally conform to the conical outer circumference of the upper part of the funnel, forming a circumferential constraint. The avoidance of the notch's positional correspondence with the funnel's inclined side eliminates potential structural interference at the corners and ensures uniform coverage of each inclined area by the reinforcing ribs. The detachable sleeve design provides rigid support during use and allows for quick separation and disposal after use. The notch arrangement at the top corner ensures that the fold creases of the reinforcing ribs perfectly match the direction of the funnel's inclined side, preventing localized warping or incomplete sealing due to angular deviations.

[0057] Furthermore, it is worth noting that, to protect the adhesive layer 200 and the connecting layer 400 before use and facilitate quick peeling, both the adhesive layer 200 and the connecting layer 400 utilize double-sided adhesive with a peelable release liner on their surface. This design of the double-sided adhesive with a peelable release liner protects the adhesive surface from contamination during storage and transportation, and allows for direct exposure of the bonding surface by peeling off the release liner during use, simplifying the assembly process. The use of double-sided adhesive instead of traditional glue in the adhesive layer ensures immediate bonding during the folding and joining of the cone-shaped units.
