Description

Technical Field

[0001] This utility model relates to bottle caps, and more particularly to double-layer bottle caps with a reinforced structure. Background Technology

[0002] A double-layered bottle cap is a type of cap designed to fit the shape of a bottle. Existing double-layered bottle caps consist of an outer cap and an inner cap nestled within the outer cap. The outer cap fits the bottle body, while the inner cap fits the bottle neck. The inner cap is typically secured to the bottle neck via a snap-fit ​​mechanism. Additionally, a slot is usually provided on the inner cap, and a strip is provided on the bottle neck to engage with the slot, thus preventing relative rotation between the double-layered bottle cap and the bottle body and ensuring a stable connection. However, because existing double-layered bottle caps rely on a slot on the inner cap to engage with the strip on the bottle neck for a stable connection, the structural strength of the double-layered bottle cap is compromised, making it prone to damage. Utility Model Content

[0003] The purpose of this invention is to provide a double-layer bottle cap with a reinforced structure to solve the problem that existing double-layer bottle caps, by configuring slots on the inner cap to stabilize the connection between the cap and the bottle body, result in compromised structural strength and easy damage.

[0004] This utility model is achieved through the following technical solution:

[0005] A double-layered bottle cap with a reinforced structure includes an outer cap with an opening facing downwards, an inner ring cap inside the outer cap, the inner ring cap extending circumferentially around the outer cap, the inner ring cap and the outer cap being spaced apart radially from each other on the outer cap, the bottom surface of the inner ring cap being higher than the bottom surface of the outer cap, and an insert extending vertically on the inner side of the outer cap, the insert extending at least partially below the inner ring cap, the cross-section of the insert gradually decreasing from top to bottom.

[0006] Furthermore, the plug extends downward from the inner top surface of the outer cover along the inner side surface of the outer cover.

[0007] Furthermore, the inner ring cover extends downward from the inner top surface of the outer cover, and the portion of the insert extending below the inner ring cover occupies 3 / 5 to 2 / 3 of the height of the outer cover.

[0008] Furthermore, the insert extends radially on the outer cover and is spaced apart from the inner ring cover to form a narrow slit.

[0009] Furthermore, there are several plug-ins, which are spaced apart on the circumference of the outer cover, and the spacing between the plug-ins and the inner ring cover is the same.

[0010] Furthermore, the portion of the plug located below the inner ring cover is defined as the insertion part, and the side of the insertion part away from the outer cover has a plurality of recesses, which are spaced apart in the vertical direction.

[0011] Furthermore, the inner top surface of the outer cover is provided with an inner plug ring extending around its circumference, and the inner ring cover is disposed around the inner plug ring and spaced apart from the inner plug ring in the radial direction of the outer cover.

[0012] Furthermore, the bottom surface of the inner plug ring is higher than the bottom surface of the inner ring cover.

[0013] Furthermore, the inner plug ring and the outer cover together form a downward-facing liquid outlet cavity, the top of the outer cover is provided with a liquid outlet communicating with the liquid outlet cavity, and a cap is provided on one side of the top of the outer cover that can rotate relative to it to open and close the liquid outlet.

[0014] Furthermore, the inner ring cover, the insert, the inner plug ring, and the cap are integrally formed on the outer cover.

[0015] The advantage of this technical solution is that by configuring the double-layered bottle cap with a reinforced structure as an outer cap and an inner ring cap, with the bottom surface of the inner ring cap being higher than the bottom surface of the outer cap, and an insert extending at least partially to the bottom of the inner ring cap on the inner side of the outer cap, the double-layered bottle cap with a reinforced structure can achieve fixation between the bottle cap and the bottle body when used together, without weakening the structural strength of the inner ring cap, and enhancing the structural strength of the outer cap. Thus, the double-layered bottle cap with a reinforced structure has good structural strength and is not easily damaged. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1-3 As shown, the double-layer bottle cap with a reinforced structure includes an outer cap 1 with its opening facing downwards, an inner ring cap 2 inside the outer cap 1, the inner ring cap 2 extending circumferentially around the outer cap 1, the inner ring cap 2 and the outer cap 1 being spaced apart radially in the outer cap 1, the bottom surface of the inner ring cap 2 being higher than the bottom surface of the outer cap 1, and an insert 3 extending vertically on the inner side of the outer cap 1, the insert 3 extending at least partially below the inner ring cap 2, the cross-section of the insert 3 gradually decreasing from top to bottom.

[0023] Accordingly, the bottle body used in conjunction with the double-layered cap with the reinforced structure has a bottle mouth, a bottle shoulder and a slot. The bottle mouth extends upward from the top of the bottle shoulder, and the slot is opened on the outer wall of the bottle shoulder with the slot width gradually narrowing from top to bottom.

[0024] When the double-layered bottle cap with reinforced structure is used in conjunction with the corresponding bottle body, the bottle mouth is inserted into the inner ring cap 2, the bottle shoulder is inserted into the outer cap 1 and abuts against the bottom surface of the inner ring cap 2, and the plug 3 is inserted into the slot to restrict the relative rotation of the bottle cap and the bottle body and lock the bottle cap onto the bottle body.

[0025] In summary, this embodiment provides a double-layer bottle cap with a reinforced structure to solve the problem that existing double-layer bottle caps, which use slots on the inner cap to stabilize the connection between the cap and the bottle body, suffer structural damage and are prone to breakage. The main solution is to configure the double-layer bottle cap with a reinforced structure as an outer cap 1 and an inner ring cap 2. The bottom surface of the inner ring cap 2 is configured to be higher than the bottom surface of the outer cap 1. An insert 3, extending at least partially below the inner ring cap 2, is provided on the inner side of the outer cap 1. This allows the double-layer bottle cap with a reinforced structure to securely fasten the cap and the bottle body when used together, without weakening the structural strength of the inner ring cap 2, while simultaneously enhancing the structural strength of the outer cap 1. Therefore, the double-layer bottle cap with a reinforced structure has good structural strength and is not easily damaged.

[0026] In this embodiment of the invention, the insert 3 extends downward from the inner top surface of the outer cap 1 along the inner side surface of the outer cap 1. This arrangement, by configuring the insert 3 to extend downward from the inner top surface of the outer cap 1 along the inner side surface of the outer cap 1, gives the double-layered bottle cap with a reinforced structure good structural strength.

[0027] In this embodiment of the invention, the inner ring cap 2 extends downward from the inner top surface of the outer cap 1, and the portion of the insert 3 extending below the inner ring cap 2 occupies 3 / 5 to 2 / 3 of the height of the outer cap 1. The height of the inner ring cap 2 occupies 1 / 6 to 1 / 5 of the height of the outer cap 1, and the height of the insert 3 occupies 5 / 6 to 4 / 5 of the height of the outer cap 1. This arrangement, by configuring the portion of the insert 3 extending below the inner ring cap 2 to occupy 3 / 5 to 2 / 3 of the height of the outer cap 1, makes the relative positions of the outer cap 1, inner ring cap 2, and insert 3 reasonably compact, resulting in good structural strength. Furthermore, the double-layered bottle cap with its reinforced structure provides a stable connection when used with the corresponding bottle body.

[0028] In this embodiment of the invention, the insert 3 extends radially in the outer cap 1 and forms a narrow slit with the inner ring cap 2 at intervals. This arrangement, by configuring the insert 3 to extend radially in the outer cap 1 and form a narrow slit with the inner ring cap 2 at intervals, gives the double-layered bottle cap with a reinforced structure good structural strength. Simultaneously, it allows the insert 3 a certain degree of mobility, facilitating its insertion into the corresponding slot on the bottle body.

[0029] In this embodiment of the invention, there are several inserts 3, which are spaced apart circumferentially on the outer cap 1, and the spacing between the inserts 3 and the inner ring cap 2 is the same. This arrangement, by configuring several inserts 3, gives the double-layered bottle cap with a reinforced structure good structural strength.

[0030] In this embodiment of the invention, the portion of the plug 3 located below the inner ring cap 2 is defined as the insertion portion 301. A plurality of recesses 302 are formed on the side of the insertion portion 301 away from the outer cap 1, and these recesses 302 are spaced apart in the vertical direction. Correspondingly, the bottom of the slot has a protrusion that matches the shape of the recess 302. This arrangement, by configuring a plurality of recesses 302 on the side of the insertion portion 301 away from the outer cap 1, ensures a stable connection between the double-layered bottle cap with its reinforced structure and the corresponding bottle body when used together.

[0031] In this embodiment of the invention, the inner top surface of the outer cap 1 is provided with an inner plug ring 5 extending circumferentially around it, and the inner ring cap 2 is arranged around the inner plug ring 5 and spaced apart from the inner plug ring 5 in the radial direction of the outer cap 1. The inner plug ring 5 is used to insert into the bottle neck. This arrangement, by configuring the inner plug ring 5 inside the outer cap 1 to engage with the bottle neck, ensures a stable connection when the double-layered bottle cap with its reinforced structure is used with the corresponding bottle body.

[0032] In this embodiment of the invention, the bottom surface of the inner stopper ring 5 is higher than the bottom surface of the inner ring cap 2. This arrangement, by configuring the bottom surface of the inner stopper ring 5 to be higher than the bottom surface of the inner ring cap 2, facilitates the insertion of the inner stopper ring 5 into the bottle opening.

[0033] In this embodiment of the invention, the inner plug ring 5 and the outer cover 1 together form a downward-opening liquid outlet cavity 102. The top of the outer cover 1 is provided with a liquid outlet 103 communicating with the liquid outlet cavity 102, and a cap 4 is provided on one side of the top of the outer cover 1, which can rotate relative to it to open and close the liquid outlet 103. The above arrangement facilitates liquid dispensing by providing a liquid outlet 103 communicating with the liquid outlet cavity 102 on the top of the outer cover 1.

[0034] In this embodiment of the invention, the inner ring cap 2, the insert 3, the inner stopper ring 5, and the cap 4 are integrally formed on the outer cap 1. This arrangement, by integrally forming the inner ring cap 2, the insert 3, the inner stopper ring 5, and the cap 4 on the outer cap 1, gives the double-layered bottle cap with a reinforced structure good structural strength.
