Abstract
Description
Technical Field
[0001] This utility model relates to the field of double-layer bottle cap technology, and in particular to a double-layer bottle cap with an embedded detachable structure. Background Technology
[0002] A double-layered bottle cap is a functional cap consisting of an inner shell and an outer shell. The outer shell has a downward-opening assembly cavity with slots on its walls. The inner shell is housed within the assembly cavity and has locking blocks that engage with the slots. The inner shell is made of opaque plastic to seal the bottle opening, while the outer shell is made of transparent plastic to create a visual contrast and enhance aesthetics. However, because the slots and locking blocks on the inner and outer shells are relatively small, the connection between the inner and outer shells via the locking blocks is unstable and prone to loosening. Furthermore, the transparent outer shell reveals the connection structure, which is unsightly. Utility Model Content
[0003] The purpose of this utility model is to provide a double-layer bottle cap with an embedded detachable structure to solve the problem that the inner shell of the existing double-layer bottle cap is housed in the assembly cavity and connected to the outer shell by a locking block, resulting in an unstable connection and easy loosening.
[0004] This utility model is achieved through the following technical solution:
[0005] A double-layer bottle cap with an embedded detachable structure includes an outer base shell and an inner shell embedded in the outer base shell. The inner shell can be detached from the outer base shell in an axial direction. The inner shell has an inner ring and an outer ring. The inner ring extends around the axis of the outer base shell, and the outer ring is disposed around the inner ring. The outer base shell has an inner hole and an outer hole. The inner hole extends along the axis of the outer base shell for the inner ring to be inserted, and the outer hole is disposed around the inner hole for the outer ring to be inserted.
[0006] Furthermore, the outer base shell has an inner base ring that forms the embedded hole. One of the inner base ring and the embedded ring is provided with a positioning strip, and the other of the two is provided with a positioning groove that engages with the positioning strip.
[0007] Furthermore, both the positioning groove and the positioning strip extend around the axis of the outer base shell.
[0008] Furthermore, the axial direction of the outer base shell is defined as the up-down direction, and the inner shell is fitted onto the outer base shell when it moves from top to bottom relative to the outer base shell, and the upper side of the positioning strip is inclined inward from top to bottom.
[0009] Furthermore, the axial direction of the outer base shell is defined as the up-down direction. When the inner shell moves from bottom to top relative to the outer base shell, it is detached from the outer base shell, and the lower side of the positioning strip extends horizontally.
[0010] Furthermore, the outer base shell has an inner base ring that forms the embedded hole. One of the inner base ring and the embedded ring is provided with a guide strip, and the other of the two is provided with a guide groove that slides with the guide strip. The guide strip extends along the axis of the outer base shell.
[0011] Furthermore, the embedded hole penetrates the outer base shell axially, and the inner side of the embedded ring is provided with threads.
[0012] Furthermore, the outer base shell also has an outer base ring and a bottom ring cover. The outer base ring, the bottom ring cover, and the inner base ring together form the outer embedded hole. The outer base ring is disposed outside the inner base ring. The bottom ring cover is connected to the lower ends of the outer base ring and the inner base ring respectively and is inclined inward from bottom to top.
[0013] Furthermore, the bottom ring cover extends around the axis of the outer base shell and is integrally formed with the inner base ring and the outer base ring.
[0014] Furthermore, the inner shell also has a dome cover, and both the inner ring and the outer ring are located on the lower side of the dome cover and are integrally formed with the dome cover.
[0015] The advantage of this technical solution is that by configuring the inner shell with an inner ring and an outer ring, and configuring the outer base shell with an inner hole and an outer hole, the inner ring and the outer ring are respectively inserted and matched with the inner hole and the outer hole, so that the inner shell interlayer is embedded in the outer base shell, and the assembly with the outer base shell is stable and not easy to loosen.

[0026] 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.
[0027] Example: Figure 1-8 As shown, the double-layer bottle cap with an embedded detachable structure includes an outer base shell 1 and an inner shell 2 embedded in the outer base shell 1. The inner shell 2 can be detached from the outer base shell 1 in the axial direction. The inner shell 2 has an inner ring 201 and an outer ring 202. The inner ring 201 extends around the axis of the outer base shell 1, and the outer ring 202 is arranged around the inner ring 201. The outer base shell 1 has an inner hole 101 and an outer hole 102. The inner hole 101 extends along the axis of the outer base shell 1 for the inner ring 201 to be inserted, and the outer hole 102 is arranged around the inner hole 101 for the outer ring 202 to be inserted. Specifically, the axial direction of the outer base shell 1 is defined as the up-down direction. When the inner shell 2 moves from top to bottom relative to the outer base shell 1, the inner ring 201 and the outer ring 202 are inserted into the inner hole 101 and the outer hole 102 respectively, so that the inner shell 2 is fitted onto the outer base shell 1. When the inner shell 2 moves from bottom to top relative to the outer base shell 1, the inner ring 201 and the outer ring 202 are removed from the inner hole 101 and the outer hole 102 respectively, so that the inner shell 2 is detached from the outer base shell 1.
[0028] In summary, this embodiment provides a double-layer bottle cap with an embedded detachable structure to solve the problem that the inner shell of existing double-layer bottle caps is housed in the assembly cavity and connected to the outer shell by a locking block, resulting in unstable connection and easy loosening. The main solution is to configure the inner shell 2 with an inner ring 201 and an outer ring 202, and the outer base shell 1 with an inner hole 101 and an outer hole 102. The inner ring 201 and the outer ring 202 are respectively inserted and fitted into the inner hole 101 and the outer hole 102. Therefore, the inner shell 2 is sandwiched and embedded in the outer base shell 1, and the assembly with the outer base shell 1 is stable and not easy to loosen. Moreover, the sandwiched embedding has a richer and more beautiful visual effect.
[0029] In this embodiment of the invention, the outer base shell 1 has an inner base ring 103 forming an embedded hole 101. The inner base ring 103 is provided with a positioning strip 104, and the embedded ring 201 is provided with a positioning groove 203 for inserting the positioning strip 104. This arrangement, by configuring the positioning strip 104 on the inner base ring 103 and the positioning groove 203 on the embedded ring 201 for inserting the positioning strip 104, ensures stable assembly between the embedded shell 2 and the outer base shell 1, preventing them from easily loosening.
[0030] In other embodiments, the positioning strip 104 is disposed on the inner ring 201, and the positioning groove 203 is disposed on the inner base ring 103.
[0031] In this embodiment of the invention, both the positioning groove 203 and the positioning strip 104 extend around the axis of the outer base shell 1. By configuring the positioning groove 203 and the positioning strip 104 to extend around the axis of the outer base shell 1, the inner shell 2 and the outer base shell 1 are stably assembled and not easily loosened.
[0032] In this embodiment of the utility model, the upper side of the positioning strip 104 is inclined inward from top to bottom. By configuring the upper side of the positioning strip 104 to be inclined inward from top to bottom, the positioning strip 104 can be smoothly inserted into the positioning groove 203 when the inner shell 2 is installed on the outer base shell 1 from top to bottom.
[0033] In this embodiment of the invention, the positioning strip 104 extends horizontally on its lower side. This arrangement, by configuring the lower side of the positioning strip 104 to extend horizontally, ensures stable assembly between the inner shell 2 and the outer base shell 1, preventing them from easily becoming loose.
[0034] In this embodiment of the invention, the inner ring 201 is provided with a guide strip 204 extending along the axis of the outer base shell 1, and the inner base ring 103 is provided with a guide groove 105 that slides with the guide strip 204. This arrangement, by configuring the guide strip 204 on the inner ring 201 and the guide groove 105 on the inner base ring 103, ensures smooth insertion of the inner shell 2 onto the outer base shell 1 from top to bottom.
[0035] In other embodiments, guide strip 204 is disposed on inner base ring 103, and guide groove 105 is disposed on inner ring 201.
[0036] In this embodiment of the invention, the inner hole 101 penetrates the outer base shell 1 axially, and the inner ring 201 is threaded on its inner side. This arrangement, by configuring the inner hole 101 to penetrate the outer base shell 1, ensures a compact and stable assembly between the inner shell 2 and the outer base shell 1.
[0037] In this embodiment of the invention, the outer base shell 1 further comprises an outer base ring 106 and a bottom ring cover 107. The outer base ring 106, the bottom ring cover 107, and the inner base ring 103 together form an external embedded hole 102. The outer base ring 106 is arranged around the inner base ring 103. The bottom ring cover 107 is connected to the lower ends of the outer base ring 106 and the inner base ring 103 respectively and is inclined inward from bottom to top. The above arrangement, by configuring the outer base shell 1 with an outer base ring 106, an inner base ring 103, and a bottom ring cover 107, with the outer base ring 106 and the inner base ring 103 alternating between inner and outer rings, and the bottom ring cover 107 located at the lower ends of the outer base ring 106 and the inner base ring 103 and inclined inward from bottom to top, makes the structure of the outer base shell 1 compact.
[0038] In this embodiment of the invention, the bottom ring cover 107 extends around the axis of the outer base shell 1 and is integrally formed with the inner base ring 103 and the outer base ring 106. This arrangement, by configuring the outer base ring 106, the inner base ring 103, and the bottom ring cover 107 as an integral unit, gives the outer base shell 1 good structural strength.
[0039] In this embodiment of the invention, the inner shell 2 also has a dome cover 205, with an inner ring 201 and an outer ring 202 both disposed on the lower side of the dome cover 205 and integrally formed with it. This arrangement, by configuring the inner ring 201, the outer ring 202, and the dome cover 205 as an integral part, gives the inner shell 2 good structural strength.
