[0031] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0032] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0033] As described in the background technology, some manufacturers of consumer goods generally set a points code or lottery code inside the container. For example, a milk powder can has a points QR code printed on the inside of its lid by a laser machine. After the consumer purchases the product, they open the product packaging cover and can see the points code on the tear-away cover. They can scan the points code to earn points.
[0034] The commonly used anti-theft designs of milk powder cans on the market mainly include a flip cover and a fixing ring. The fixing ring is used to be fixedly connected to the main body of the milk powder can. The flip cover and the fixing ring are connected by a disposable sealing buckle, which plays an anti-theft role.
[0035] The above design can only ensure the anti-theft effect between the flip cover and the fixing ring. The fixing ring and the main body of the milk powder can are generally fixed with a buckle. In the product circulation link, before the product is sold, other personnel can easily remove the fixing ring and the flip cover from the milk powder can intactly without damaging the disposable seal buckle of the product packaging cover, scan the QR code in advance or directly cover the QR code, misleading consumers and resulting in consumers being unable to enjoy rights and interests by accumulating points. Manufacturers are unable to verify the source information of the product through the QR code information, disrupting the market's operating order.
[0036] In order to avoid the above situation, a disposable warning label is usually attached between the fixing ring and the milk powder can. When the fixing ring is detached from the milk powder can, the warning label tears to remind consumers that the milk powder can has been opened. However, the warning label is easy to imitate and cannot completely guarantee the anti-theft properties of the milk powder can and the fixing ring.
[0037] Based on the above related description, a container cover is provided in one or more embodiments of the present application to solve the problem of poor anti-theft performance of container covers in the related art.
[0038] The following is a description of the same with reference to the accompanying drawings.
[0039] like Figures 1 to 4 As shown, the container cover in the embodiment of the present application is used for connecting with the container body 400, and the container cover specifically includes a fixing ring 100, a cover body 200 and at least one fastener 300.
[0040] Among them, the cover body 200 is opened and closed and is arranged on the fixing ring 100; at least one fastener 300 is arranged on the side of the fixing ring 100 away from the cover body 200, and the fastener 300 has a locking state of being flipped to fit the inner wall of the fixing ring 100; in the locked state, the fastener 300 is tightly engaged with the container body 400 inserted into the fixing ring 100.
[0041] From the above description, it can be seen that in the container lid of the embodiment of the present application, the lid body 200 is openable and closable and is arranged on the fixing ring 100 to ensure that the container lid can be opened and closed normally, and at least one fastener 300 is arranged on the side of the fixing ring 100 away from the lid body 200, and the fastener 300 has a locking state of being flipped to fit the inner wall of the fixing ring 100; in the locked state, the fastener 300 is tightly engaged with the container body 400 inserted into the fixing ring 100, thereby, when the container body 400 is inserted into the fixing ring 100, the side wall of the container body 400 presses the fastener 300 to make the container body 400 and the fixing ring 100 firmly connected, and when the fixing ring 100 is forcibly and violently detached from the container body 400, the fastener 300 will be significantly deformed and damaged, thereby playing a role in preventing the product from being tampered with and enhancing the anti-theft performance.
[0042] In the embodiment of the present application, the container body 400 can be a related container for storing items, such as a milk powder can, a medicine bottle, a tea can, a cosmetic bottle or an experimental chemical barrel, etc. The container cover is correspondingly arranged on the open end 403 of each container body 400 to seal the container body 400. In this regard, the embodiment of the present application does not make absolute limitations on the type and shape of the container cover and the container body 400.
[0043] In addition, the directional words such as "upper" and "lower" mentioned in the embodiments of the present application are described with reference to the placement direction of the milk powder can, that is, the container cover is located above the container body 400 and covers the container body 400.
[0044] Generally, the fixing ring 100 is an annular member that passes through the opening, and the fixing ring 100 is connected to the container body 400. Since the cover body 200 is connected to the fixing ring 100, when the cover body 200 is sealed on the fixing ring 100, the container cover as a whole also seals the container body 400. When the cover body 200 opens the fixing ring 100, the container cover as a whole opens, exposing the open end 403 of the container body 400.
[0045] Exemplarily, the cover 200 and the fixing ring 100 are rotatably connected, that is, the cover 200 can be turned over relative to the fixing ring 100, and the rotational connection between the cover 200 and the fixing ring 100 can be achieved by a pivot member that penetrates both of them, or by a flexible hinge connection. In addition, a disposable sealing structure should also be provided between the cover 200 and the fixing ring 100 to provide an anti-theft and anti-secondary restoration effect between the cover 200 and the fixing ring 100. The disposable sealing structure between the cover 200 and the fixing ring 100 can refer to the milk powder cover structure in the related art, and will not be described in detail in the embodiments of the present application.
[0046] like Figure 2 As shown, the fastener 300 includes a flexible portion 301 connected to the fixing ring 100 , and a clamping portion 302 connected to the flexible portion 301 , and the thickness of the clamping portion 302 is greater than the thickness of the flexible portion 301 .
[0047] In the above embodiment, the buckle 300 is an integrally formed part, the flexible portion 301 and the clamping portion 302 are integrally injection molded, and the buckle 300 can be made of plastic materials such as polypropylene and polyethylene.
[0048] Here, although the clamping part 302 and the flexible part 301 are made of the same material and are an integral injection-molded component, the clamping part 302 is more inclined to increase the pressure between the buckle 300 and the container body 400 by using the thickness change; the function of the flexible part 301 is to make the buckle 300 adhere to the inner wall surface of the fixing ring 100 as a whole after being deformed by the external force. Therefore, when the thickness of the clamping part 302 is greater than that of the flexible part 301, the position of the flexible part 301 is more likely to deform, so as to facilitate the subsequent switching to the locked state.
[0049] Since the thickness of the snap-on portion 302 is greater than that of the flexible portion 301, when the snap-on component 300 is in a locked state, the container body 400 extending into the fixing ring 100 is tightly fitted with the snap-on portion 302 to form a barb structure, and the pressing effect between the snap-on component 300 and the container body 400 is more stable. When the container body 400 is violently disassembled from the fixing ring 100 by external force, the snap-on portion 302 and the flexible portion 301 on the snap-on component 300 are forcibly deformed and cannot be restored to the original locked state. Therefore, the snap-on component 300 can play an anti-theft and anti-secondary restoration effect.
[0050] In some embodiments, the flexible portion 301 and the clamping portion 302 on the fastener 300 can be made of different materials. For example, the flexible portion 301 is made of a low-toughness material, such as polystyrene, polytetrafluoroethylene, etc., and the clamping portion 302 is made of polypropylene, polypropylene, etc., and the two are connected by bonding or hot-melt welding. When the container body 400 and the fixing ring 100 are violently disassembled and separated, the flexible portion 301 will be deformed with the separation action of the container body 400, and the low-toughness material characteristics will cause the flexible portion 301 to break, making the fastener 300 unable to recover, thereby playing an anti-theft role.
[0051] like Figure 3 and Figure 4 As shown, in some embodiments, the clamping portion 302 is configured with a transition guide surface 303, which extends obliquely to the flexible portion 301, and the transition guide surface 303 is configured to guide the container body 400 into the fixing ring 100 in a locked state.
[0052] Figure 4 In the figure, the transition guide surface 303 guides the thicker clamping portion 302 to transition to the thinner flexible portion 301. When the fastener 300 is in a locked state, the transition guide surface 303 causes the horizontal cross-section of the fastener 300 to gradually increase from bottom to top, that is, the fitting clamping pressure between the container body 400 and the fastener 300 gradually increases. This arrangement can facilitate guiding the container body 400 to extend into the fixing ring 100, thereby facilitating the initial assembly of the fixing ring 100 and the container body 400.
[0053] In the above embodiment, the clamping portion 302 is a block structure of equal thickness. As a replaceable implementation, the clamping portion 302 and the flexible portion 301 are integrally formed into a wedge-shaped strip with a triangular cross-section. It is sufficient to ensure that the container body 400 can be pressed and clamped with the clamping portion 302 when inserted into the fixing ring 100.
[0054] like Figure 4 As shown, in some embodiments, the fixing ring 100 includes a main body 101 and an avoidance portion 102 disposed on a side of the main body 101 away from the cover body 200 , the avoidance portion 102 is bent outward relative to the main body 101 , and the avoidance portion 102 is connected to the flexible portion 301 .
[0055] The avoidance portion 102 is arranged to expand outwardly relative to the main body 101. The avoidance portion 102 and the main body 101 are integrally formed components. A step is formed at the joint position between the avoidance portion 102 and the main body 101. The flexible portion 301 of the snap 300 is connected to the avoidance portion 102. When the container body 400 is inserted into the fixing ring 100, it first contacts the avoidance portion 102 of the fixing ring 100. The outward expansion design of the avoidance portion 102 provides room for movement for the container body 400, which can facilitate the initial insertion of the container body 400 into the fixing ring 100, thereby making it easier for the container body 400 to contact the transition guide surface 303 of the snap 300.
[0056] In some embodiments, further, in the locked state, at least part of the buckle 300 is in contact with the main body 101. Exemplarily, the flexible portion 301 of the buckle 300 is in contact with the avoidance portion 102, the clamping portion 302 of the buckle 300 is in contact with the main body 101, the inner diameter of the main body 101 is smaller than the inner diameter of the avoidance portion 102, and the thickness of the clamping portion 302 is greater than the thickness of the flexible portion 301, so that the thickness of the clamping portion 302 and the main body 101 is larger, and the force of the container body 400 and the clamping portion 302 pressing against each other is larger, thereby ensuring the clamping effect of the container body 400 and the buckle 300.
[0057] like Figure 1 As shown, in some embodiments, there are multiple buckles 300, and the multiple buckles 300 are arranged at intervals along the circumferential direction of the fixing ring 100. Providing multiple buckles 300 can enhance the tightness between the container body 400 and prevent the container body 400 from being separated from the fixing ring 100.
[0058] It should be noted that, in some embodiments, when the flexible portion 301 on the fastener 300 is connected to the avoidance portion 102, the fastener 300 is in a position that fits the inner wall of the fixing ring 100. That is, the fastener 300 after connection is in a locked state regardless of whether it is connected to the container body 400. The flexible portion 301 and the avoidance portion 102 can be connected by ultrasonic welding or directly integrally injection molded. This setting enables the fastener 300 to be in a locked state even if it is not assembled with the container body 400, which facilitates the subsequent assembly process between the container body 400 and the fixing ring 100.
[0059] An embodiment of the present application further provides a container with a lid, comprising the container lid as described above, and further comprising a container body 400, wherein the container body 400 is used to be connected to the container lid.
[0060] In the above structure, since the container with a cover adopts the container cover in the above embodiment, it also has the advantages and benefits brought by the above battery pack, which will not be further described here.
[0061] In some embodiments, the container body 400 has an open end 403 , and the side wall of the container body 400 near the open end 403 is configured with a radially outwardly protruding clamping platform 402 , which is used to be clamped and connected with the latch 300 to prevent the latch 300 from detaching from the container body 400 .
[0062] The container body 400 in the above embodiment is opened upward, and the clamping platform 402 provided at the edge of the opening end 403 of the container body 400 can cooperate with the buckle 300 to form a clamping limit in the height direction, thereby further improving the fixing effect between the container body 400 and the buckle 300. Exemplarily, the clamping platform 402 can be an annular boss provided around the container body 400, or a plurality of clamping platforms can be provided at intervals along the circumference of the container body 400.
