Description
3 1. Field of Invention 4 The present invention relates to a cap, and more particularly to a cap assembly for cold steeping drinks that can hold steeping materials and improve 6 sealability of the steeping materials and safety of drinks.
7 2. Description of the Related Art 8 Steeping materials such as tea leaves, dried vegetables and fruit, Chinese 9 traditional medicine, leaven and concentrated vinegar are brewed in cold water for hours to make cold brewed drinks. Because some harmful and bad-tasting 11 substances dissolve in hot water when steeping materials are steeped in hot water, 12 cold steeped drinks taste better and are healthier than drinks steeped in hot water.
13 Taking cold steeping tea as an example, because tannic acid and caffeine 14 cause a bitter taste and are difficult to extract from tea leaves in cold water, cold steeping tea results in a smooth taste and prevents disadvantages like palpitations, 16 stomach ulcers, insomnia and low calcium absorption rate caused by caffeine.
17 Cold steeping tea is also helpful to reduce a person's blood pressure and uric acid 18 because less theophylline is extracted. In addition, catechins like EC, EGC
and 19 EGCg extract effectively from tea leaves in cold water and have healthy effects such as reducing free radials and cholesterol, producing anticarcinogens, 21 antioxidants for antiaging and antibacterial agents, preventing stomach ulcers, 22 protecting the cardiovascular system and increasing helpful bacteria in the 23 intestinal tract.
24 With reference to Figs. 5 and 6, a conventional cap assembly for cold 1 steeping tea as disclosed in the applicant's prior art is mounted on a mouth (61A) 2 of a bottle (60A) and comprises a body ( l0A), a punch assembly (20A), a safety 3 ring (30A) and a connector strip (50A).
4 The body (10A) is mounted on the mouth (61A) and has a cap connector, a primary tube (12A), a cover (16A), a drive tube (14A) and a chamber (13A).
6 The cap connector is screwed on an outer thread formed on the mouth (61 A) and 7 has a side wall and a shoulder. The side wall has an upper edge, a lower edge, an 8 inner surface and an inner thread. The inner thread is formed on the inner surface 9 of the cap connector and screws onto the outer thread on the mouth (61 A).
The shoulder is formed on and protrudes in from the upper edge of the side wall and 11 has an outer surface and an inner surface. The primary tube (12A) is formed on 12 and protrudes coaxially down from the inner surface of the shoulder and has a 13 distal end. The cover (16A) is mounted detachably on the distal end of the 14 primary tube (12A). The drive tube (14A) is formed on and protrudes coaxially up from the outer surface of the shoulder and has an inner surface, an outer 16 surface, a drive thread and an annular lip (144). The drive thread is formed on the 17 inner surface of the drive tube (14A). The annular lip (144) is formed on and 18 protrudes out from the outer surface of the drive tube (14A). The chamber (13A) 19 is defined in the primary tube (12A) and the drive tube (14A) above the cover (16A) and holds steeping materials (70A).
21 The punch assembly (20A) is mounted on the body (10A) and comprises 22 a drive cap (24A) and a punch tube (22A). The drive cap (24A) has a top and a 23 side wall. The top is circular and has an outer edge and a bottom surface.

6 The thread is formed on the outer surface of the punch tube (22A) and screws 7 into the drive thread on the drive tube (14A).
8 The safety ring (30A) is connected to the cap connector, engages a 9 flange on a bottle (60A), is removable so the cap assembly can be removed from the bottle (60A) and has an upper edge, an inner surface, a connector and 11 multiple resilient teeth (32A). The connector is formed on the upper edge of the 12 safety ring (30A), is connected to the lower edge of the cap connector and tears 13 to allow the cap assembly to be removed from a bottle (60A). The resilient teeth 14 (32A) are formed on and protrude in and up from the inner surface of the safety ring (30A) and engage a flange on the bottle (60A) to hold the cap assembly on a 16 bottle (60A).
17 The connector strip (50A) is connected detachably to the punch 18 assembly (20A) and has an upper edge, an inner surface, a connector, multiple 19 teeth (51 A), a crack and a pull tab. The connector is formed on the upper edge of the connector strip (50A), is connected to the lower edge of the drive cap (24A) 21 and is torn to remove the connector strip (60A) and allow the drive cap (24A) to 22 be removed. The teeth (51A) are formed on and protrude in from the inner 23 surface of the connector strip (50A) and engage a notch between the annular lip 24 (144) on the drive tube (14A) and the shoulder on the cap connector. The crack is 1 defined in the connector strip (50A). The pull tab is mounted near the crack to 2 separate the connector strip (50A) from the cap connector. Though the 3 conventional cap assembly is capable of holding steeping materials (70A) and 4 performing cold steeping, safety of the drinks and sealability of the steeping materials (70A) still need to be improved and enhanced.
6 To overcome the shortcomings, the present invention provides a cap 7 assembly for cold steeping drinks to mitigate or obviate the aforementioned 8 problems.
The primary objective of the present invention is to provide a cap 11 assembly for cold steeping drinks that is mounted on a bottle, holds steeping 12 materials and improves sealability and safety of the drinks.

2 With reference to Figs. 1, 2 and 3, a cap assembly in accordance with the 3 present invention for cold steeping drinks is mounted on a mouth (61) of a bottle 4 (60) having a top edge, an outer thread and a flange (62) and comprises a body (10), a punch assembly (20), a safety ring (30) and a connector strip (50).
6 The body (10) is mounted on the bottle mouth (61) and has a cap 7 connector (11), a primary tube (12), a cover (16), a drive tube (14) and a chamber 8 (13).
9 The cap connector (11) screws onto the outer thread of the mouth (61) and comprises a side wall and a shoulder. The side wall has an upper edge, a 11 lower edge, an inner surface and an inner thread. The inner thread is formed on 12 the inner surface of the side wall and screws onto the outer thread of the mouth 13 (61). The shoulder is formed on and protrudes in from the upper edge of the side 14 wall and has an outer surface and an inner surface.
The primary tube (12) is formed on and protrudes coaxially down from 16 the inner surface of the shoulder and has an inner surface, an outer surface, a 17 distal end, at least one annular seal (121) and a sealing lip (122). The at least one 18 annular seal (121) is forrned on the inner surface of the primary tube (12). The 19 sealing lip (122) is formed between the inner surface of the shoulder and the outer surface of the primary tube (12). When the body (10) is screwed onto the 21 mouth (61), the sealing lip (122) presses against the top edge of the mouth (61) to 22 prevent air or moisture from entering the bottle (60) and improves sealability.
23 The cover (16) may be plastic, metallic or airtight papery film and is 24 attached to the distal end of the primary tube (12).
1 The drive tube (14) is formed on and protrudes coaxially up from the 2 outer surface of the shoulder and has an inner surface, an outer surface, a top 3 edge, multiple outer pawl teeth (141), an outer thread (142) and multiple top 4 pawl teeth (143). The outer pawl teeth (141) are formed between the top surface of the shoulder and the outer surface of the drive tube (14). The outer thread (142) 6 is formed on the outer surface of the drive tube (14). The top pawl teeth (143) are 7 formed on the top edge of the drive tube (14).
8 The chamber (13) is defined in the primary tube (12) and the drive tube 9 (14) to hold steeping materials (70).
The punch assembly (20) is mounted on the body (10) and comprises a 11 drive cap (21), a punch tube (22) and multiple upper teeth (23). The drive cap (21) 12 is mounted slidably on the drive tube (14) and comprises a top and a side wall.
13 The top is circular and has a bottom surface and an outer edge. The side wall is 14 formed on and protrudes down from the outer edge of the top and has a lower edge, an inner surface and an optional inner thread (211). The inner thread (211) 16 is formed on the inner surface of the side wall and corresponds to and is screwed 17 onto the outer thread (142) of the drive tube (142).
18 The punch tube (22) is fonned coaxially on and protrudes down from the 19 bottom surface of the top, is mounted slidably in the drive tube (14) and the primary tube (12), is longer than the body (10) and has an outer surface and a 21 distal end. The outer surface of the punch tube (22) presses against the at least 22 one annular seal (121) to prevent air or moisture from entering the chamber (13) 23 in the body (10). With further reference to Fig. 4, the distal end of the punch tube 24 (22) may be oblique, selectively extends through the distal end of the primary 1 tube (12) when the drive cap (21) is screwed fully on the body (10) and separates 2 the cover (16) from the distal end of the primary tube (12) to release the steeping 3 materials (70) in the chamber (13).
4 The upper teeth (23) are formed on the bottom surface of the top of the drive cap (21) between the outer surface of the punch tube (22) and the inner 6 surface of the side wall of the drive cap (21) and correspond to the top pawl teeth 7 (143) on the drive tube (14). When the drive cap (21) is screwed fully on the 8 body (10), the upper teeth (23) engage the top pawl teeth (143) to prevent the 9 punch assembly (20) from loosening from the body (10) and safety of the cap assembly is improved.
11 The safety ring (30) is connected to the cap connector (11), engages a 12 flange (62) on a bottle (60), is removable so the cap assembly can be removed 13 from the bottle (60) and has an upper edge, an inner surface, multiple connectors 14 (31) and a locking ring (32). The connectors (31) are tearable, are formed on the upper edge of the safety ring (31) and are connected to the lower edge of the side 16 wall of the cap connector (11). The locking ring (32) is formed on the inner 17 surface of the safety ring (30) and abuts the flange (62) on the mouth (61) of the 18 bottle (60) when the body (10) is loosened from the bottle mouth (61) to prevent 19 the safety ring (30) from moving with the body (10). Consequently, the connectors (31) are torn, and the safety ring (30) remains around the mouth (61) 21 of the bottle (60) to indicate that the body (10) has been loosed from the mouth 22 (61) of the bottle (60).
23 The connector strip (50) is connected detachably to the punch assembly 24 (20) and has an upper edge, an inner surface, multiple connectors (52), multiple 1 inner pawl teeth (51), a crack and a pull tab (53). The connectors (52) are formed 2 on the upper edge of the connector strip (50), are connected to the lower edge of 3 the side wall of the drive cap (21) and are torn to remove the connector strip (50) 4 and allow the drive cap (24) to be removed. The inner pawl teeth (51) are formed 5 on and protrude in from the inner surface of the connector strip (50) and engage 6 the outer pawl teeth (141) on the drive tube (14) to keep the punch assembly (20) 7 from loosening from the body (10). The crack is defined in the connector strip 8 (50). The pull tab (53) is mounted near the crack to separate the connector strip 9 (50) from the cap connector (11). To release the steeping materials, the pull tab 10 (53) is pulled to tear the connectors (52) on the connector strip (50) and to 11 remove the connector strip (50) from the punch assembly (20) and allow the 12 punch assembly to be turned.
13 Even though numerous characteristics and advantages of the present 14 invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only.
16 Changes may be made in detail, especially in matters of shape, size and 17 arrangement of parts within the principles of the invention to the full extent 18 indicated by the broad general meaning of the terms in which the appended 19 claims are expressed.

2 With reference to Figs. 1, 2 and 3, a cap assembly in accordance with the 3 present invention for cold steeping drinks is mounted on a mouth (61) of a bottle 4 (60) having a top edge, an outer thread and a flange (62) and comprises a body (10), a punch assembly (20), a safety ring (30) and a connector strip (50).
6 The body (10) is mounted on the bottle mouth (61) and has a cap 7 connector (11), a primary tube (12), a cover (16), a drive tube (14) and a chamber 8 (13).
9 The cap connector (11) screws onto the outer thread of the mouth (61) and comprises a side wall and a shoulder. The side wall has an upper edge, a 11 lower edge, an inner surface and an inner thread. The inner thread is formed on 12 the inner surface of the side wall and screws onto the outer thread of the mouth 13 (61). The shoulder is formed on and protrudes in from the upper edge of the side 14 wall and has an outer surface and an inner surface.
The primary tube (12) is formed on and protrudes coaxially down from 16 the inner surface of the shoulder and has an inner surface, an outer surface, a 17 distal end, at least one annular seal (121) and a sealing lip (122). The at least one 18 annular seal (121) is forrned on the inner surface of the primary tube (12). The 19 sealing lip (122) is formed between the inner surface of the shoulder and the outer surface of the primary tube (12). When the body (10) is screwed onto the 21 mouth (61), the sealing lip (122) presses against the top edge of the mouth (61) to 22 prevent air or moisture from entering the bottle (60) and improves sealability.
23 The cover (16) may be plastic, metallic or airtight papery film and is 24 attached to the distal end of the primary tube (12).
1 The drive tube (14) is formed on and protrudes coaxially up from the 2 outer surface of the shoulder and has an inner surface, an outer surface, a top 3 edge, multiple outer pawl teeth (141), an outer thread (142) and multiple top 4 pawl teeth (143). The outer pawl teeth (141) are formed between the top surface of the shoulder and the outer surface of the drive tube (14). The outer thread (142) 6 is formed on the outer surface of the drive tube (14). The top pawl teeth (143) are 7 formed on the top edge of the drive tube (14).
8 The chamber (13) is defined in the primary tube (12) and the drive tube 9 (14) to hold steeping materials (70).
The punch assembly (20) is mounted on the body (10) and comprises a 11 drive cap (21), a punch tube (22) and multiple upper teeth (23). The drive cap (21) 12 is mounted slidably on the drive tube (14) and comprises a top and a side wall.
13 The top is circular and has a bottom surface and an outer edge. The side wall is 14 formed on and protrudes down from the outer edge of the top and has a lower edge, an inner surface and an optional inner thread (211). The inner thread (211) 16 is formed on the inner surface of the side wall and corresponds to and is screwed 17 onto the outer thread (142) of the drive tube (142).
18 The punch tube (22) is fonned coaxially on and protrudes down from the 19 bottom surface of the top, is mounted slidably in the drive tube (14) and the primary tube (12), is longer than the body (10) and has an outer surface and a 21 distal end. The outer surface of the punch tube (22) presses against the at least 22 one annular seal (121) to prevent air or moisture from entering the chamber (13) 23 in the body (10). With further reference to Fig. 4, the distal end of the punch tube 24 (22) may be oblique, selectively extends through the distal end of the primary 1 tube (12) when the drive cap (21) is screwed fully on the body (10) and separates 2 the cover (16) from the distal end of the primary tube (12) to release the steeping 3 materials (70) in the chamber (13).
4 The upper teeth (23) are formed on the bottom surface of the top of the drive cap (21) between the outer surface of the punch tube (22) and the inner 6 surface of the side wall of the drive cap (21) and correspond to the top pawl teeth 7 (143) on the drive tube (14). When the drive cap (21) is screwed fully on the 8 body (10), the upper teeth (23) engage the top pawl teeth (143) to prevent the 9 punch assembly (20) from loosening from the body (10) and safety of the cap assembly is improved.
11 The safety ring (30) is connected to the cap connector (11), engages a 12 flange (62) on a bottle (60), is removable so the cap assembly can be removed 13 from the bottle (60) and has an upper edge, an inner surface, multiple connectors 14 (31) and a locking ring (32). The connectors (31) are tearable, are formed on the upper edge of the safety ring (31) and are connected to the lower edge of the side 16 wall of the cap connector (11). The locking ring (32) is formed on the inner 17 surface of the safety ring (30) and abuts the flange (62) on the mouth (61) of the 18 bottle (60) when the body (10) is loosened from the bottle mouth (61) to prevent 19 the safety ring (30) from moving with the body (10). Consequently, the connectors (31) are torn, and the safety ring (30) remains around the mouth (61) 21 of the bottle (60) to indicate that the body (10) has been loosed from the mouth 22 (61) of the bottle (60).
23 The connector strip (50) is connected detachably to the punch assembly 24 (20) and has an upper edge, an inner surface, multiple connectors (52), multiple 1 inner pawl teeth (51), a crack and a pull tab (53). The connectors (52) are formed 2 on the upper edge of the connector strip (50), are connected to the lower edge of 3 the side wall of the drive cap (21) and are torn to remove the connector strip (50) 4 and allow the drive cap (24) to be removed. The inner pawl teeth (51) are formed 5 on and protrude in from the inner surface of the connector strip (50) and engage 6 the outer pawl teeth (141) on the drive tube (14) to keep the punch assembly (20) 7 from loosening from the body (10). The crack is defined in the connector strip 8 (50). The pull tab (53) is mounted near the crack to separate the connector strip 9 (50) from the cap connector (11). To release the steeping materials, the pull tab 10 (53) is pulled to tear the connectors (52) on the connector strip (50) and to 11 remove the connector strip (50) from the punch assembly (20) and allow the 12 punch assembly to be turned.
13 Even though numerous characteristics and advantages of the present 14 invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only.
16 Changes may be made in detail, especially in matters of shape, size and 17 arrangement of parts within the principles of the invention to the full extent 18 indicated by the broad general meaning of the terms in which the appended 19 claims are expressed.
