Description

Cup lid cutting mold, cup lid manufacturing process and cup lid Technical Field

[0001] This application relates to cup lids, and in particular to a cup lid cutting mold, a cup lid manufacturing process, and a cup lid. Background Technology

[0002] Traditional cup lids are molded using plastic injection molding. To secure them to the rim of the cup, an inwardly protruding flange is designed on the inner wall. However, in practical use, the cup body is often subjected to stress, causing the rim to change shape and preventing the lid from fitting securely. Alternatively, assembly errors may exist between the cup body and the lid, preventing a tight fit. Furthermore, plastic injection-molded lids are prone to twisting and deformation during demolding, have significant manufacturing errors, and are relatively expensive.

[0003] Therefore, it is necessary to provide a novel and progressive cup lid cutting mold, cup lid manufacturing process, and cup lid to solve the above problems.

[0004] Summary of the Invention

[0005] The main purpose of this application is to provide a cup lid cutting mold, a cup lid manufacturing process, and a cup lid. The cup lid can be formed by vacuum forming, and then the cup lid cutting mold is used to break the continuous structure of the cup lid to form at least one cutting line. The at least one cutting line allows a part of the cup lid to be bent relatively, so that in actual use, the bent part of the cup lid can be bent and embedded into the rim of the cup body to achieve a tight fit.

[0006] To achieve the above objectives, this application provides a cup lid cutting mold for cutting a cup lid, the cup lid comprising a lid portion and an outer ring portion, the outer ring portion protruding laterally from the lid portion. The cup lid cutting mold includes: an alignment unit and a cutting unit. The alignment unit includes at least one through-hole facing one side of the outer ring portion; the cutting unit includes at least one blade located on the other side of the outer ring portion, the at least one blade movably penetrating the at least one through-hole; wherein the at least one blade is used to break the continuous structure of the outer ring portion, thereby forming at least one cutting mark on the outer ring portion.

[0007] In one embodiment, the alignment unit further includes a receiving seat and a positioning member. The receiving seat encloses a receiving space for accommodating the cup lid. The positioning member extends into the receiving space and is connected to the receiving seat, thereby the positioning member and the receiving seat together clamp and position the cup lid.

Detailed Implementation

[0022] The present application will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present application. However, the embodiments described are not intended to limit the present application. The use of "a" or "at least one" before the terms mentioned herein is not a limitation on the quantity, and may also refer to "multiple" depending on the requirements. Such variations in quantity are also within the scope of the intended protection.

[0023] Please refer to Figures 1 to 8, which show an embodiment of this application. The cup lid cutting mold 1 of this application is used to cut a cup lid 4. The cup lid 4 includes a lid portion 41 and an outer ring portion 42. The outer ring portion 42 protrudes laterally from the lid portion 41. The cup lid cutting mold 1 includes: a pair of alignment units 2 and a disconnection unit 3.

[0024] The alignment unit 2 includes at least one through-hole 21 facing one side of the outer ring portion 42. The disconnection unit 3 includes at least one blade 31 located on the other side of the outer ring portion 42, and the at least one blade 31 is movably inserted into the at least one through-hole 21; wherein, the at least one blade 31 is used to disconnect the continuous structure of the outer ring portion 42, thereby forming at least one cutting mark 45 on the outer ring portion 42, so as to allow the portions of the outer ring portion 42 located on opposite sides of the at least one cutting mark 45 to move relative to each other, so as to abut against the rim 52 of the cup body 5.

[0025] The alignment unit 2 further includes a receiving seat 22 and a positioning member 26. The receiving seat 22 encloses a receiving space 24 for accommodating the cup lid 4. The positioning member 26 extends into the receiving space 24 and is connected to the receiving seat 22. Thus, the positioning member 26 and the receiving seat 22 together clamp and position the cup lid 4, so that the cup lid 4 is kept in a stressed and stretched state, so that the at least one blade 31 can quickly and easily pierce and break the continuous structure of the cup lid 4. The at least one through-hole 21 includes a first through-hole 211 and a second through-hole 212. The first through-hole 211 is located in the receiving seat 22, and the second through-hole 212 is located in the positioning member 26. Furthermore, the receiving seat 22 includes a first component 23 and a second component 25. The first component 23 encloses the receiving space 24, and the second component 25 is detachably received in the receiving space 24 along a first direction 6. The second component 25 and the positioning member 26 are located on opposite sides of the cup lid 4 in the first direction 6. The hardness of the second component 25 is greater than that of the first component 23, so that a more rigid structure can withstand external forces, or, different styles can be changed according to the shape and size of the cup lid 4.

[0026] The disconnection unit 3 further includes a drive member 32, a base 34, at least one slide rail 36, and at least one slide block 37. The at least one slide rail 36 is positioned on the base 34. The at least one slide block 37 is slidably disposed on the at least one slide rail 36 between a working position and a storage position. The at least one blade 31 is positioned on the at least one slide block 37. The drive member 32 is movably disposed on the base 34 to force the at least one slide block 37 to move toward the working position, thereby causing the at least one blade 31 to penetrate the at least one through-hole 21.

[0027] In this embodiment, the number of at least one through-hole 21, the number of at least one blade 31, the number of at least one slide rail 36 and the number of at least one slide block 37 are equal and multiple, and the number of at least one cutting mark 45 is also multiple, wherein the cross-section of each blade 31 is U-shaped. Furthermore, the driving member 32 includes a plurality of pressing portions 33, which are correspondingly arranged with the plurality of slides 37 in the first direction 6. Each pressing portion 33 includes a guide surface 331 and a stop surface 332 arranged laterally. The guide surface 331 is inclined to the first direction 6. When the driving member 32 approaches the base 34 along the first direction 6, the guide surface 331 slides against the slide 37 to move it to the working position along the first direction 6, and then the blade 31 moves along the first direction 6. The stop surface 332 is used to stop the slide 37 at a predetermined position in the first direction 6.

[0028] During use, the disconnecting unit 3 extends into the receiving space 24 along the first direction 6 so that multiple blades 31 are located in the receiving space 24. Then, by moving a single driving member 32, multiple blades 31 are quickly driven to operate simultaneously. When multiple slides 37 are in the working position, multiple blades 31 protrude from the receiving space 24 through multiple through holes 21 and simultaneously pierce through the cup lid 4 to achieve the purpose of cutting off the continuous structure of the cup lid 4.

[0029] Preferably, a plurality of guide rods 35 are positioned on the base 34 extending along the first direction 6, and the drive member 32 is movably slidably mounted on the plurality of guide rods 35 along the first direction 6, so that the plurality of guide rods 35 can ensure that the drive member 32 moves in a straight line without rotating.

[0030] In another preferred embodiment, the disconnecting unit 3 further includes at least one spring-back unit 38, which springs against the base 34 and the slide 37, so that the slide 37 normally tends to move toward the storage position. In this embodiment, the number of the at least one spring-back unit 38 is multiple and equal to the number of slides 37. In this way, when the driving member 32 moves away from and does not abut against the multiple slides 37, the multiple slides 37 will move toward the center of the base 34, thereby driving the multiple blades 31 to retract.

[0031] This application also provides a cup lid manufacturing process, comprising the following steps: positioning the thermoformed cup lid 4 on the alignment unit 2, the cup lid 4 including a lid portion 41 and an outer ring portion 42, the outer ring portion 42 protruding laterally from the lid portion 41, the alignment unit 2 including a plurality of through-holes 21, the plurality of through-holes 21 being positioned facing one side of the outer ring portion 42; positioning a plurality of blades 31 of the disconnecting unit 3 on the other side of the outer ring portion 42, and driving the plurality of blades 31 toward the plurality of through-holes 21, the plurality of blades 31 being inserted into the plurality of through-holes 21 in a way that breaks the continuous structure of the outer ring portion 42, thereby forming a plurality of cutting marks 45 on the outer ring portion 42.

[0032] This application further provides a cup lid 4, which includes: a main body and a plurality of cutting marks 45. The main body is formed by vacuum forming and includes a lid portion 41 and an outer ring portion 42. The lid portion 41 covers the mouth 51 of the cup body 5, and the outer ring portion 42 extends laterally from the lid portion 41 to cover the rim 52 of the cup body 5. The plurality of cutting marks 45 are formed by cutting the continuous structure of the outer ring portion 42 with a plurality of blades 31, thereby dividing the outer ring portion 42 into a main body 43 and a plurality of bent portions 44. The plurality of bent portions 44 can be bent relative to the main body 43 to engage with the rim 52.

[0033] Preferably, the cup lid 4 further includes at least one reinforcing rib 46, which is disposed on the outer ring portion 42 to enhance the local structural strength.

[0034] In this embodiment, there are multiple reinforcing ribs 46, and the multiple cutting marks 45 are arranged at equal intervals along the circumference of the cover portion 41. Furthermore, at least a portion of the multiple reinforcing ribs 46 is located within the multiple bending portions 44, ensuring that the multiple bending portions 44 have sufficient strength to engage with the edge 52 and are not easily dislodged.

[0035] The embodiments described above are merely preferred embodiments for the purpose of fully illustrating this application, and the scope of protection of this application is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on this application are all within the scope of protection of this application. The scope of protection of this application is determined by the claims.
