Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bottles, and specifically relates to a bottle body with an internal and external thread structure. Background Technique
[0002] As a common packaging container, bottles are widely used in the packaging of various beverages, oils and other products. Their diverse shapes and materials enable them to adapt to different types of liquids and liquid products, thus meeting the needs of consumers.
[0003] Currently, people often use bottles to hold water when going out to meet their drinking needs at any time and carry the bottles in their bags. However, the existing bottle caps are mainly fixed by means of threaded connections. After long-term use, this connection is prone to breakage or slipping of the teeth, resulting in the bottle cap being unable to close tightly. In addition, the bottle may rub against other items in the bag or the bottle cap may become loose due to shaking during the carrying process, thereby causing liquid leakage, which brings inconvenience to people. Content of the Utility Model
[0004] The purpose of the utility model is to provide a bottle body with an internal and external thread structure in which the connection method of the bottle cap is reliable and liquid leakage is avoided.
[0005] To achieve the above purpose, the technical solution of the utility model is as follows.
[0006] A bottle body with an internal and external thread structure includes a bottle body. At the upper end of the bottle body, there is a bottle mouth. A bottle cap is sleeved outside the bottle mouth. The outer surface of the bottle mouth is provided with a first external thread, and the inner wall of the bottle cap is provided with a first internal thread adapted to the first external thread. A circular tube is installed inside the bottle cap, and the circular tube is coaxially arranged inside the bottle mouth. The inner wall of the bottle mouth is provided with a second internal thread, and the outer surface of the circular tube is provided with a second external thread adapted to the second internal thread.
[0007] It can be seen that through the settings of the first external thread, the first internal thread, the circular tube and the second internal thread, when the bottle cap is tightened, an internal and external double-thread connection can be achieved. When one set of threads breaks or slips, the other set of threads can still provide a tight closing effect, enabling the entire bottle to still be able to continue to be used, avoiding the occurrence of liquid leakage, and avoiding the need to repurchase the bottle, reducing resource waste and saving economic costs.
[0008] Furthermore, convex strips are installed on the outer surface of the bottle cap, and fixed arc teeth are evenly installed on the lower surface of the convex strips. An installation tube is installed on the outer surface of the bottle body, and a movable arc tooth is installed on the upper side of the installation tube through an elastic member, and the arc surface of the movable arc tooth corresponds to the arc surface of the fixed arc tooth.
[0009] By setting the elastic member, an upward elastic thrust can be applied to the movable arc-shaped teeth. Therefore, in the process of tightening the bottle cap clockwise, as the bottle cap gradually descends, it drives the arc surface of the fixed arc-shaped teeth to contact and squeeze the arc surface of the movable arc-shaped teeth, thereby driving the movable arc-shaped teeth to shrink downward, so that the bottle cap can rotate normally. When the bottle cap is tightened, self-locking is achieved. If the bottle cap is rotated counterclockwise, the vertical surface of the fixed arc-shaped teeth will be against the vertical surface of the movable arc-shaped teeth, thereby avoiding the situation that the bottle cap may be loosened due to friction with other items in the bag or shaking during carrying, thereby causing liquid leakage, and is convenient for people to use.
[0010] Furthermore, the elastic part includes a movable block arranged inside the mounting tube, a guide rod is installed on the upper surface of the movable block, and the upper end of the guide rod passes through the outside of the mounting tube, and the movable arc tooth is installed on the top of the guide rod, and a spring is arranged inside the mounting tube, and the two ends of the spring are respectively abutted against the inner wall of the mounting tube and the movable block.
[0011] Under the action of the spring, an upward thrust can be applied to the movable block, and then an upward elastic thrust can be applied to the movable arc-shaped teeth through the guide rod. When the movable arc-shaped teeth are squeezed, the movable block can be driven to compress the spring downward, so that the movable arc-shaped teeth can shrink downward.
[0012] Furthermore, a through groove is formed on the outer surface of the mounting tube, a lever is mounted on the outer surface of the movable block, and an end of the lever passes through the through groove and extends to the outside of the mounting tube.
[0013] When the bottle cap needs to be opened, the lever can be pushed downward to drive the movable block to move downward, thereby driving the movable arc-shaped teeth to separate from the fixed arc-shaped teeth, so that the bottle cap can be opened normally.
[0014] Furthermore, the through groove is an L-shaped structure.
[0015] When the lever is pushed, it is first driven to move downward, and then slides horizontally, so that the lever is stuck in the horizontal groove of the through groove, so the position of the lever can be fixed, and there is no need to continuously press the lever during the process of opening the bottle cap, which is convenient for use.
[0016] Furthermore, a sealing ring is provided on the top wall of the bottle cap, and the sealing ring corresponds to the upper end of the bottle mouth.
[0017] By setting the sealing ring, the sealing performance of the bottle cap can be improved after it is tightened, thereby avoiding the occurrence of liquid leakage.
[0018] Furthermore, the outer surface of the bottle cap is evenly provided with anti-skid stripes, and the anti-skid stripes are in the shape of vertical stripes.
[0019] By setting the anti-slip stripes, the friction between the bottle cap and the hand can be increased when rotating the bottle cap, reducing the possibility of hand slipping.
[0020] Further, a recessed portion is provided at the bottom of the bottle body.
[0021] Through the provision of the recessed portion, the bottle body can stand more stably and is not prone to tilting or sliding. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0029] The present utility model will be described in detail below with reference to the accompanying drawings.
[0030] As Figures 1-6 shown, a bottle body with an internal and external thread structure includes a bottle body 100. An opening 101 is provided at the upper end of the bottle body 100. A bottle cap 102 is sleeved outside the opening 101. A first external thread 103 is provided on the outer surface of the opening 101. A first internal thread 104 adapted to the first external thread 103 is provided on the inner wall of the bottle cap 102. A circular tube 105 is installed inside the bottle cap 102, and the circular tube 105 is coaxially arranged inside the opening 101. A second internal thread 106 is provided on the inner wall of the opening 101. A second external thread 107 adapted to the second internal thread 106 is provided on the outer surface of the circular tube 105.
[0031] When tightening the bottle cap 102, the bottle cap 102 is sleeved on the outside of the bottle mouth 101, and the round tube 105 is located inside the bottle mouth 101. Then, rotate the bottle cap 102 clockwise, which can drive the mutual engagement between the first external thread 103 and the first internal thread 104, the second internal thread 106, and the second external thread 107 at the same time, realizing the connection of the inner and outer double-layer threads. When one set of threads breaks or slips, the other set of threads can still provide a tight closing effect, enabling the whole bottle to continue to be used, avoiding liquid leakage, and eliminating the need to repurchase the bottle, reducing resource waste and saving economic costs.
[0032] Specifically, a rib 200 is installed on the outer surface of the bottle cap 102, and fixed arc teeth 201 are evenly installed on the lower surface of the rib 200. An installation tube 202 is installed on the outer surface of the bottle body 100. An active arc tooth 203 is installed on the upper side of the installation tube 202 through an elastic member 300, and the arc surface of the active arc tooth 203 corresponds to the arc surface of the fixed arc tooth 201. Through the setting of the elastic member 300, an upward elastic thrust can be applied to the active arc tooth 203. Therefore, during the process of screwing the bottle cap 102 clockwise, as the bottle cap 102 gradually descends, it drives the arc surface of the fixed arc tooth 201 to contact and squeeze the arc surface of the active arc tooth 203, thereby driving the active arc tooth 203 to contract downward, enabling the bottle cap 102 to rotate normally. After the bottle cap 102 is tightened, if the bottle cap 102 is rotated counterclockwise, the vertical surface of the fixed arc tooth 201 will abut against the vertical surface of the active arc tooth 203, thus preventing possible friction with other items in the bag or loosening of the bottle cap 102 due to shaking during carrying, and further avoiding liquid leakage, which is convenient for people to use.
[0033] Specifically, the elastic member 300 includes a movable block 301 arranged inside the installation tube 202. A guide rod 302 is installed on the upper surface of the movable block 301, and the upper end of the guide rod 302 penetrates to the outside of the installation tube 202, and the active arc tooth 203 is installed at the top of the guide rod 302. A spring 303 is arranged inside the installation tube 202, and both ends of the spring 303 are in contact with the inner wall of the installation tube 202 and the movable block 301 respectively. Under the action of the spring 303, an upward thrust can be applied to the movable block 301, and then an upward elastic thrust can be applied to the active arc tooth 203 through the guide rod 302. When the active arc tooth 203 is squeezed, the movable block 301 can be driven to compress the spring 303 downward, enabling the active arc tooth 203 to contract downward.
[0034] Specifically, a through groove 400 is formed on the outer surface of the installation pipe 202. A lever 401 is installed on the outer surface of the movable block 301. The end of the lever 401 passes through the through groove 400 and extends to the outside of the installation pipe 202. When the bottle cap 102 needs to be opened, the lever 401 can be first pushed downwards to drive the movable block 301 to move downwards, and then the movable arc-shaped tooth 203 can be driven to separate from the fixed arc-shaped tooth 201, so that the bottle cap 102 can be normally opened.
[0035] Specifically, the through groove 400 is of an L-shaped structure. When the lever 401 is pushed, it is first driven to move downwards, and then slides horizontally, so that the lever 401 is stuck in the horizontal groove of the through groove 400. Therefore, the position of the lever 401 can be fixed, and there is no need to continuously press the lever 401 during the process of opening the bottle cap 102, which is convenient for use.
[0036] Specifically, a sealing ring 500 is arranged on the top wall of the bottle cap 102. The sealing ring 500 corresponds to the upper end of the bottle mouth 101. Through the arrangement of the sealing ring 500, the sealing performance of the bottle cap 102 can be improved after it is tightened, and the situation of liquid leakage can be avoided.
[0037] Specifically, anti-slip stripes 600 are uniformly arranged on the outer surface of the bottle cap 102. The anti-slip stripes 600 are vertical stripes. Through the arrangement of the anti-slip stripes 600, the friction between the bottle cap 102 and the hand can be increased when the bottle cap 102 is rotated, and the situation of hand slipping can be reduced.
[0038] Specifically, a recessed part 700 is arranged at the bottom of the bottle body 100. Through the arrangement of the recessed part 700, the bottle body 100 can stand more stably and is not easy to tilt or slide.
[0039] The above is a detailed description of the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation manners of the present utility model are only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several equivalent substitutions or obvious modifications are made, and the performance or use is the same, and all should be regarded as belonging to the patent protection scope determined by the claims submitted by the present utility model.
