[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] As attached Figure 1-5A wet wipe cover shown in the figure comprises a wet wipe cover body, the wet wipe cover body is composed of an embedded cover 1, an external frame 2 and an elastic device, wherein a gap is formed between the inner embedded cover 1 and the external frame 2, and the gap is connected by a polypropylene plastic connecting strip 3, the polypropylene plastic connecting strip 3 at the movable turning point between the inner embedded cover 1 and the external frame 2 forms a connecting shaft 4, and the elastic device is installed on the back side of the wet wipe cover and connects the inner embedded cover 1 and the external frame 2; the inner embedded cover 1, the external frame 2 and the polypropylene plastic connecting strip 3 for connecting the inner embedded cover 1 and the external frame 2 are all made of polypropylene material; the interlocking structure of the inner embedded cover 1 and the external frame 2 is not a fixed structure, it can be a two-piece assembly structure, it can be a semi-enclosed structure, and it can also be a fully enclosed structure; the front side of the inner embedded cover 1 and the external frame 2 is the side away from the wet wipe bag, and the back side is the side close to the wet wipe bag; the surface of the inner embedded cover 1 is provided with a pull groove 5 for opening the inner embedded cover 1.
[0033] Specifically, in this structure, the inner cover 1 and the outer frame 2 of the wet wipe cover are fixed in relative position by a polypropylene plastic connecting strip 3 and are in the same plane. Figure 2 It is a reverse view, an elastic device is provided between the connected side of the inner cover 1 and the outer frame 2, and the connection axis 4 can be flexibly defined, that is, when the inner cover 1 and the outer frame 2 are left-right structures, the connection axis 4 is the connection point between the inner cover 1 and the outer frame 2;
[0034] The reverse side of the wet wipe cover is pasted and covered on one side of the extraction hole of the wet wipe bag, and the embedded cover 1 can completely cover the wet wipe extraction hole;
[0035] When the user uses fingers or nails to open the inner cover 1 included in the wet wipes cover pasted on the wet wipes bag, the polypropylene plastic connecting strip 3 used to connect the inner cover 1 and the external frame 2 is broken and no longer restored, and the inner cover 1 is flexibly rotated along the connecting axis 4 in the opposite direction of the external frame 2 away from the inner cover 1 in a semicircular trajectory, and the elastic device ensures that the inner cover 1 and the external frame 2 are not separated, and the elastic device generates internal stress when it is increased and stretched. After the finger or nail leaves the inner cover 1, the internal stress of the elastic device does work, so that the inner cover 1 and the external frame 2 are in the same plane again, maintaining the integrity of the wet wipes cover and the covering of the wet wipes extraction hole;
[0036] It is worth noting that the connection axis 4 can be flexibly defined, and it can be understood that the elastic device can be set at any edge adjacent to the embedded cover 1 and the external frame 2, and this place is used as the connection axis 4 (the connection axis 4 itself is the elastic device or the fulcrum when lifting one side of the embedded cover 1).
[0037] In this embodiment, as shown in the attached Figure 2 , 3As shown in FIG. 4 , the elastic device includes an elastic rubber rope 6, which is installed on the reverse side of the wet wipes cover and connects the inner cover 1 with the outer frame 2 at both ends. The two ends of the elastic rubber rope 6 can be bonded to the inner cover and the outer frame correspondingly by hot melt adhesive.
[0038] In this embodiment, threaded holes for installing an elastic rubber rope 6 are provided on the reverse sides of the inner cover 1 and the external frame 2, and fixing rings 7 are provided at both ends of the elastic rubber rope 6. The internal threads of the fixing rings 7 are provided with fastening screws 8, and the two ends of the elastic rubber rope 6 are detachably connected to the inner cover 1 and the external frame 2 through the fastening screws 8 inside the fixing ring 7 and the threaded holes provided on the reverse sides of the inner cover 1 and the external frame 2.
[0039] Specifically, in this structure, when the elastic rubber cord 6 belonging to the elastic device is installed on the back of the wet wipes cover body for connecting the inner cover 1 and the outer frame 2, the fixing rings 7 at both ends of the elastic rubber cord 6 are aligned with the threaded holes opened on the back of the inner cover 1 and the outer frame 2, and the fixing rings 7 are fixed by tightening the screws 8, thereby realizing the installation of the elastic rubber cord 6. This installation method can facilitate the subsequent removal and replacement of the elastic rubber cord 6 if it breaks, and is convenient for installation.
[0040] In another embodiment of the installation of the elastic device, the two ends of the rubber band can be melted and then pasted to the back of the inner cover 1 and the outer frame 2, or a sticky elastic tape can be used for pasting and installation. The advantage of using this method is that it saves production costs and reduces production steps.
[0041] The above-mentioned various installation methods for the elastic device are all within the scope of consideration of the present invention, and are determined according to actual production conditions. Example
[0042] Different from Example 1, the embedded cover 1 and the external frame 2 in this embodiment can be a semi-enclosed structure or a fully-enclosed structure, the connecting axis 4 can be any adjacent edge of the embedded cover 1 and the external frame 2, and the other structures remain unchanged.
[0043] In this embodiment, when the connecting shaft 4 can be any adjacent side of the embedded cover 1 and the external frame 2, when the cover needs to be opened, during the production process of the wet wipe cover, a non-cutting stripe blade is set on the knife roller, and the stripe blade is parallel to the connecting shaft 4, and a stripe pattern is pressed and cut on the front of the embedded cover 1 (not shown in the figure);
[0044] The inner cover 1 is provided with strips parallel to the connecting axis 4. When the inner cover 1 is touched by fingers and the strips are pressed toward the connecting axis 4, the inner cover 1 is subjected to an upward pressing force due to the resistance at the connecting pull 4. At this time, the connecting axis 4 is the fulcrum for the inner cover 1 to be lifted.
[0045] The wet wipes cover of the utility model is produced differently from the existing wet wipes cover:
[0046] When producing the wet wipes cover, polypropylene plastic particles are melted at high temperature and pressed into flat strips by an extruder. The continuous production line conveys the extruded flat strips to the slitting forming rollers for slitting. The circular roller cutter has blades of different depths to achieve different cutting purposes. The shallow blade is responsible for the initial separation between the embedded cover 1 and the external frame 2, while the deep blade is responsible for completely cutting the single wet wipes cover from the continuous strip.
[0047] In addition, the special non-cutting blade on the round roller can form a specific concave and convex pattern or logo to increase brand recognition for the product. Each wet wipes cover after slitting is composed of an inner cover 1 and an outer frame 2, and elastic devices such as rubber elastic ropes, rubber bands or elastic tapes are fixed on the back of the two. These elastic devices are fixed in the corresponding positions after being slightly stretched at both ends, providing resilience when closed. The fixing method may involve hot melt bonding, pasting or screw connection to ensure that the elastic device can be firmly connected to the inner cover 1 and the outer frame 2. During the slitting process, the precise control of the depth of the round roller cutter is to form polypropylene plastic connecting strips 3, which serve as the connection points between the inner cover 1 and the outer frame 2, leaving only enough connection strength to maintain the relative position of the two. When the inner cover 1 is lifted, these polypropylene plastic connecting strips 3 can be easily broken, so that the inner cover 1 can be opened freely. At this time, the polypropylene plastic connecting strips 3 at the movable flipping point between the inner cover 1 and the outer frame 2 form a connecting axis 4, so that the inner cover 1 can be opened freely at the outer frame 2.
[0048] Compared with the existing wet wipe covers, the wet wipe cover of the present application simplifies the production process of traditional wet wipe covers, reduces mold costs and demolding processes, and improves production efficiency, thereby reducing overall production costs. It adopts a continuous assembly line production method, avoids the time wasted waiting for mold cooling and demolding in the traditional injection molding process, and achieves fast and efficient production. Moreover, the new process allows the use of less material to produce the wet wipe cover, reduces the consumption of raw materials, and maintains the basic performance of the product. The design of the embedded cover 1 and the addition of the elastic device make the wet wipe cover easy to open and reopen, providing a better user experience. Due to the action of the elastic device, the embedded cover 1 can automatically close after being released, preventing the wet wipe liquid from volatilizing and extending the shelf life of the wet wipe.
[0049] In summary, the utility model effectively solves the problems of high cost and complicated production process of wet wipe covers in the prior art by simplifying the production process, reducing material consumption, improving production efficiency and optimizing product usage experience, and has significant economic and practical value.
[0050] Specifically:
[0051] Elastic device: such as rubber band, elastic tape and elastic rubber rope 6, both ends of which are slightly stretched and fixed to the back of the wet wipes cover of the embedded cover 1 and the external frame 2;
[0052] Polypropylene plastic connecting strip 3: It is formed when the roller blade cuts the wet wipe cover body, and the inner cover 1 and the outer frame 2 are not completely cut off. The position of the blade that does not completely cut off is shallower than that of the blade that completely cuts off. A small amount of residue is left between the inner cover 1 and the outer frame 2, which plays a role in fixing the relative position of the inner cover 1 and the outer frame 2;
[0053] Roller cutter: Function 1: Cut the strip body so that the wet wipes cover is an independent individual and moves along the production line; Function 2: Complete the formation of the polypropylene plastic connecting strip 3, that is, the embedded cover 1 and the external frame 2 are not completely cut off;
[0054] Connecting shaft 4: The main body of the connecting shaft 4 is the position where the rubber band, elastic tape or elastic rubber rope 6 or the filament continues to connect the inner cover 1 and the external frame 2 after being disconnected. The first function is to keep the inner cover 1 and the external frame 2 inseparable and not affect the opening of the inner cover 1. The second function is that the rubber band, elastic tape or elastic rubber rope 6 is slightly stretched. After the inner cover 1 is opened, the stretching distance increases, and its resilience is increased, which will form an assist when the cover is closed. The third function is that the rubber band, elastic tape or elastic rubber rope 6 is soft and does not affect the opening of the inner cover 1. The fourth function is that after the cover is closed, the remaining retraction stress of the rubber band, elastic tape or elastic rubber rope 6 will make the inner cover 1 and the connecting shaft 4 a fulcrum, generate a downward force, and close to the wet wipes extraction hole.
[0055] Fixing by elastic device: Solution 1, the rubber band is mostly made of rubber, and the two ends are heated to melt parts before fixing. The melted parts are pasted on the back of the wet wipe cover before solidifying, which can be fixed. After fixing, the rubber band is cut off to paste the next wet wipe cover to be pasted; Solution 2, use elastic tape, and the adhesive side of the tape is directly pasted on the back of the wet wipe cover. After fixing, the elastic tape is cut off to paste the next wet wipe cover to be pasted; Solution 3, the two ends of the elastic rubber rope 6 are detachably connected to the embedded cover 1 and the external frame 2 through the fastening screws 8 inside the fixing ring 7 and the threaded holes opened on the back of the embedded cover 1 and the external frame 2. Once the elastic rubber rope 6 is exercised or the elasticity is insufficient, it can be removed and replaced, and the installation is convenient and quick.
[0056] Improved production speed: The injection and demoulding time of the traditional wet wipes cover process is reduced. This process directly extrudes the strip body through the shaping mouth, and the knife roller cuts to form the cover body.
[0057] When in use, since the wet wipes cover is extruded, a cutter is used to separate the inner cover 1 and the outer frame 2, and a small amount of polypropylene plastic connecting strip 3 remains between the inner cover 1 and the outer frame 2, and the outer frame 2 can be pasted on the wet wipes bag. When the user opens the inner cover 1, the inner cover 1 is flipped away from the wet wipes bag through the groove 5 on the inner cover 1. At this time, the polypropylene plastic connecting strip 3 used to connect the inner cover 1 and the outer frame 2 is broken and can no longer be restored, while the polypropylene plastic connecting strip 3 at the movable part between the inner cover 1 and the outer frame 2 will not be broken, and at this time it serves as a connecting shaft 4 (the connecting shaft 4 serves as a fulcrum for the inner cover 1 to open and close inside the external frame 2, and the position of the connecting shaft 4 can be flexibly defined according to the situation).
[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
