Description

TECHNICAL FIELD

[0001] The utility model relates to the field of drink container outer package product technology, especially to a pop can connecting cover. BACKGROUND

[0002] The pop can is a common drink packaging method on the market, and the pop can type drink occupies a large consumer market. After the consumer buys the pop can type drink, the pop can type drink is difficult to carry after being opened due to the pop can packaging, and must be drunk at one time. For this phenomenon, the corresponding pop can type drink sealing cover and other products appear on the market, and most of the products on the market adopt the scheme of directly fastening the sealing cover and the outer ring of the top of the pop can through pressure to reseal the pop can.

[0003] However, after the pop can is opened, the gas in the pop can will be discharged through the pop opening, so that the pop can does not have enough strength to support, and after the sealing cover is fastened through pressure, the pop can is often deformed under pressure, thereby affecting the sealing effect of the sealing cover on the pop can.

[0004] Therefore, how to better seal the opened pop can type drink is a technical problem to be solved at present. UTILITY MODEL CONTENT

[0005] The utility model aims at providing a pop can connecting cover, which realizes repeated opening and closing of the pop can type drink packaging after being opened.

[0006] In order to realize the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A pop can connecting cover comprises a cover body and a locking ring. The cover body has a circumferential outer wall, at least one elastic locking strip is arranged on the circumferential outer wall, and each elastic locking strip can be elastically deformed towards the inside of the cover body under the action of external force. The locking ring has a circumferential inner wall, the circumferential inner wall is sleeved on the circumferential outer wall and can rotate coaxially along the circumferential outer wall, and a locking protruding structure is arranged on the circumferential inner wall corresponding to each elastic locking strip. When the locking ring is rotated relative to the cover body to a preset angle, the locking protruding structure abuts against the corresponding elastic locking strip, so that the elastic locking strip fastens the top of the can body through elastic deformation.

[0008] Further, a guide protruding structure is arranged in the inside of the cover body, and the guide protruding structure is used for positioning and extending into the pop opening.

[0009] Further, at least one through slot structure is formed in the circumferential outer wall, each through slot structure extends along the circumferential direction of the circumferential outer wall, each elastic locking strip comprises a first end portion and a second end portion, each first end portion is connected with the end portion of the corresponding through slot structure, and each second end portion is spaced apart from the other end of the corresponding through slot structure by a preset distance.

[0010] Further, the circumferential outer wall is provided with a first thread, the circumferential inner wall is provided with a second thread corresponding to the first thread, and the locking ring is coaxially rotatable relative to the cover through meshing of the second thread and the first thread.

[0011] Further, each second end portion is protruded relative to the circumferential outer wall.

[0012] Further, the top of the cover is provided with a first through hole and a second through hole for communicating with the easy-pull opening, and the top of the cover is further provided with a first hinged structure and a second hinged structure, the first hinged structure is hinged with a straw, and the second hinged structure is hinged with a pressing cap, the circumferential side of the straw is provided with a closed protruding structure, the closed protruding structure is matched with the outer shape size of the second through hole, when the straw is rotated to a first angle through the first hinged structure, the pipeline of the straw is communicated with the first through hole, and when the straw is rotated to a second angle through the second hinged structure, the closed protruding structure closes the second through hole.

[0013] Further, the circumferential outer wall is further provided with a handle structure.

[0014] It can be seen that the utility model discloses a kind of easy-pull can connecting covers, which can be buckled on the top of the can body of easy-pull can after opening, and the locking and separation of the top of the can body by the rotation of the locking ring on the cover is realized.The cover is provided with an elastic locking strip, and the locking ring is provided with a locking protruding structure corresponding to the elastic locking strip.When the user buckles the cover on the top of the can body, the locking protruding structure on the locking ring can be made to abut against its corresponding elastic locking strip by rotating the locking ring.Under the action of the external force of the locking protruding structure on its corresponding elastic locking strip, the elastic locking strip can be elastically deformed and locked against the circumferential side of the top of the can body, so that the connection between the easy-pull can connecting cover and the easy-pull can is realized.The user can drink the beverage in the easy-pull can through the rotatable pressing cap and straw on the top of the cover, and when the user cannot finish drinking the beverage in the easy-pull can at one time, the easy-pull opening is resealed by rotating the straw and the pressing cap.The easy-pull can connecting cover avoids directly using external vertical pressure to tighten and seal the easy-pull can, which can prevent the serious deformation of the can body of the easy-pull can under vertical pressure, and effectively solves the technical problems existing in the prior art.

[0035] As Figures 1 to 11As shown, according to the embodiment of the utility model, provide a zip -top can connecting cover. The zip -top can connecting cover including cover body 1 and locking ring 2, locking ring 2 is through its circumferential inner wall 201 is set in cover body 1's circumferential outer wall 101, locking ring 2 can rotate along cover body 1's circumferential outer wall 101 relative to cover body 1.

[0036] Preferably, as Figures 1 to 4 As shown, the circumferential outer wall 101 of the cover body 1 is provided with a plurality of elastic locking strips 103, and the circumferential inner wall 201 of the locking ring 2 is provided with a block-shaped locking protruding structure 202 corresponding to each elastic locking strip 103. When the locking ring 2 is rotated to a preset angle relative to the cover body 1, the locking protruding structure 202 abuts against the corresponding elastic locking strip 103, so that the elastic locking strip 103 is clamped on the top of the can body 6 by elastic deformation.

[0037] Preferably, as Figures 1 to 4 As shown, the circumferential outer wall 101 of the cover body 1 is provided with a plurality of through groove structures 102 extending along the circumferential outer wall 101, one end of each through groove structure 102 is connected with the first end 103a of the corresponding elastic locking strip 103, and the second end 103b of each elastic locking strip 103 is spaced apart from the other end of the corresponding through groove structure 102 by a preset distance to form an avoidance groove 102a capable of accommodating the corresponding locking protruding structure 202. When the cover body 1 is not locked to the can body 6 by the locking ring 2, the plurality of locking protruding structures 202 on the circumferential inner wall 201 of the locking ring 2 are respectively arranged in the corresponding avoidance groove 102a. When the locking ring 2 is rotated relative to the cover body 1 to lock the cover body 1 to the can body 6, each locking protruding structure 202 is in close contact with the corresponding elastic locking strip 103. During the rotation of the locking ring 2 relative to the cover body 1, each locking protruding structure 202 respectively provides a pressing force to the corresponding elastic locking strip 103 towards the inside of the cover body 1, so that each elastic locking strip 103 is elastically deformed towards the can body 6, and finally realizes the locking between the zip -top can connecting cover and the can body 6.

[0038] Preferably, as Figure 3 As shown, the second end 103b of each elastic locking strip 103 is protruded relative to the circumferential outer wall 101 of the cover body 1. The protruded second end 103b of the elastic locking strip 103 can play a protection role after the locking of the locking ring 2. After the locking of the locking ring 2, each elastic locking strip 103 is locked to the can body 6 by elastic deformation, and the protruded second end 103b can limit the locking protruding structure 202 on the circumferential inner wall 201 of the locking ring 2, preventing the user from causing the rotation of the locking ring 2 relative to the cover body 1 by slight misoperation, thereby further improving the locking effect of the locking ring 2 on the cover body 1.

[0039] Preferably, as shown in Figure 11 The inner part of the cover 1 is provided with a waterproof protruding structure 104 corresponding to the top of the can body 6 and protruding towards the top of the can body 6. The waterproof protruding structure 104 matches the concave part of the top of the can body 6 in size. When the easy-open can connecting cover is connected to the top of the can body 6, the waterproof protruding structure 104 can be in close contact with the top surface of the can body 6, so as to prevent the beverage in the can body 6 from flowing out through the installation gap between the cover 1 and the can body 6.

[0040] Preferably, as shown in Figures 2 to 4 The circumferential outer wall 101 of the cover 1 is provided with a first thread 105, and the circumferential inner wall 201 of the locking ring 2 is provided with a second thread 203 matching the first thread 105. The locking ring 2 is engaged with the first thread 105 on the cover 1 through the second thread 203, so that the locking ring 2 can rotate relative to the cover 1, and the engagement between the first thread 105 and the second thread 203 further improves the connection between the locking ring 2 and the cover 1.

[0041] Preferably, as shown in Figures 1 to 11 The cover 1 is provided with a first through hole 106 and a second through hole 107, which are respectively used for communication with the easy-open mouth of the can body 6 after being opened. The top of the cover 1 is provided with a first hinge structure 108 and a second hinge structure 109, and the first hinge structure 108 and the second hinge structure 109 are respectively hinged with the straw 3 and the gland 4. The circumferential side of the straw 3 is provided with a closing protruding structure 301 capable of closing the second through hole 107. When the straw 3 is rotated to a first angle relative to the cover 1 through the first hinge structure 108, the pipeline 302 of the straw 3 can be in communication with the easy-open mouth through the first through hole 106, and at this time the easy-open mouth is also in communication with the external atmospheric pressure through the second through hole 107, so that the user can drink the beverage in the can body 6 through the straw 3. When the straw 3 is rotated to a second angle relative to the cover 1 through the second hinge structure 109, the outer wall of the straw 3 closes the first through hole 106, so that the pipeline 302 of the straw 3 is disconnected from the easy-open mouth, and the closing protruding structure 301 on the straw 3 simultaneously closes the second through hole 107, so that the easy-open can connecting cover seals the can body 6. Finally, the gland 4 can be rotated through the second hinge structure 109 to press the straw 3 at the second angle, so as to prevent the straw 3 from being misrotated and further improve the sealing effect of the straw 3 on the first through hole 106 and the second through hole 107.

[0042] Preferably, as shown in Figures 1 to 6As shown, a first limiting structure 110 is provided on the lid 1, and a second limiting structure 204 and a third limiting structure 205 are provided at intervals around the locking ring 2. When the can connecting lid is not locked to the can body 6, the first limiting structure 110 is located between the second limiting structure 204 and the third limiting structure 205, and the first limiting structure 110 is in contact with the second limiting structure 204. At this time, each locking protrusion 202 is built into its corresponding relief groove 102a, and each elastic locking strip 103 does not produce elastic deformation. When the can lid is locked to the can body 6, the locking ring 2 rotates relative to the lid 1, causing the first limiting structure 110 to move from the second limiting structure 204 toward the third limiting structure 205 until the first limiting structure 110 and the third limiting structure 205 are in contact. During this process, each locking protrusion 202 abuts against its corresponding elastic locking strip 103, causing each elastic locking strip 103 to undergo elastic deformation toward the inside of the lid 1, thereby locking the can lid to the can body 6. During the relative rotation between the locking ring 2 and the lid 1, the first limiting structure 110 can only move between the second limiting structure 204 and the third limiting structure 205, thus preventing the user from applying excessive force or angle, which could damage the can lid.

[0043] Optionally, such as Figures 7 to 11 As shown, the can lid has two guide protrusions 111 inside. These protrusions correspond to the can's opening and extend inwards. The spacing between the two protrusions 111 matches the opening diameter, allowing both protrusions to simultaneously extend into the can along the edge of the opening. When the lid is attached to the can body 6, the protrusions 111 position the lid by the edge of the opening. Furthermore, when a user uses an extension tube to drink from the can via the straw 3's tube 302, the protrusions 111 protect the extension tube from damage caused by the sharp edge of the opening.

[0044] Optionally, such as Figure 1 As shown, a handle structure 112 can also be provided on the outer circumferential wall 101 of the lid body 1 of the can connecting lid, so that the user can hold the canned beverage locked by the can connecting lid through the handle structure 112.

[0045] Optionally, such as Figure 1 As shown, a hanging ring 5 can also be hinged to the outer circumferential wall 101 of the lid 1 of the can connecting lid through a third hinge structure 113. The user can hang the canned beverage after it has been locked by the can connecting lid through the hanging ring 5.

[0046] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0047] The cover body 1 of the pull-ring can lid is buckled on the top of the can body 6 of the pull-ring can after being opened, and the locking and separation of the pull-ring can lid to the top of the can body 6 are realized by the rotation of the locking ring 2 sleeved on the cover body 1. When the user buckles the cover body 1 on the top of the can body 6, the locking convex structure 202 on the locking ring 2 can be made to abut against the corresponding elastic locking strip 103 by rotating the locking ring 2. Under the action of the external force of the locking convex structure 202 on the elastic locking strip 103, the elastic locking strip 103 is elastically deformed and locked against the top of the can body 6, so that the connection between the pull-ring can lid and the pull-ring can is realized. The user can drink the beverage in the pull-ring can through the pressure cover 4 and the straw 3 hinged on the top of the cover body 1, and when the user cannot finish drinking the beverage in the pull-ring can at one time, the pull-ring opening is resealed through the hinged straw 3 and pressure cover 4. The hanging ring 5 and handle structure 112 arranged on the cover body 1 can facilitate the user to hang or hold the can body 6 locked by the pull-ring can lid.

[0048] Compared with the prior art, the pull-ring can lid provided by the utility model realizes the locking between the pull-ring can lid and the can body 6 by the relative rotation between the locking ring 2 and the cover body 1, so that each locking convex structure 202 on the circumferential inner wall 201 of the locking ring 2 provides pressure to the corresponding elastic locking strip 103 on the circumferential outer wall 101 of the cover body 1, so that each elastic locking strip 103 is elastically deformed towards the can body 6, and finally the locking between the pull-ring can lid and the can body 6 is realized. The pull-ring can lid provided by the utility model avoids the problem that the pull-ring can is directly sealed by using external vertical pressure, so that the can body 6 of the pull-ring can is severely deformed when subjected to vertical pressure. While realizing the repeated opening and closing of the pull-ring can beverage, the technical problems existing in the prior art are effectively solved.

[0049] The above only describes the preferred embodiments of the utility model, and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
