Description

Technical Field

[0001] This utility model relates to the field of polyester bottle technology, specifically a double-shrink polyester bottle for laboratory use. Background Technology

[0002] "Double sealing" is a technology that achieves tight sealing or fastening through multiple structural designs. It is commonly used in containers that require high sealing performance (such as laboratory polyester bottles). The core is to form "double protection" through two independent sealing / fastening structures, which greatly improves the sealing effect and stability.

[0003] Traditional laboratory polyester bottles have a simple sealing structure, often relying on a single thread or gasket for sealing. This makes them prone to seal failure due to thread wear and aging of the seal, leading to liquid leakage or gas evaporation. At the same time, some polyester bottles lack a dedicated drainage structure, making it easy for liquid to remain or spill when pouring, affecting the safety and convenience of experimental operations and failing to meet the laboratory's requirements for high sealing and ease of operation. Utility Model Content

[0004] The purpose of this invention is to provide a double-shrink polyester bottle for laboratory use to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laboratory double-shrink polyester bottle, comprising: a bottle body, a cap assembly, and an external thread on the outer wall of the bottle body opening, and further comprising: vertical strip grooves formed on the inner walls of both sides of the bottle body, elastic components installed on the inner walls of both strip grooves, and a sealing component rotatably installed on the outer wall of the opposite side of the two elastic components, support plates installed on the inner walls of both sides of the bottle body, and a drainage groove formed on the inner wall of the bottle body opening side.

[0006] The bottle cap assembly includes a cap body, a sealing ring adhered to the inner wall of the top of the cap body, and a pressure ring installed on the inner wall of the top of the cap body.

[0007] The inner wall of the cover has a threaded groove, which is compatible with the external thread.

[0008] The elastic component includes a fixed rod, a spring sleeved on the outside of the fixed rod, and a slider.

[0009] The sealing assembly includes a traction rod, a semi-circular plate rotatably connected to one end of the bottom of the traction rod, and a sealing strip adhered to the outer wall of one side of the semi-circular plate.

[0010] A gap is left between the support plate and the inner wall of the top of the bottle, and the semi-circular plate slides into this gap.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model discloses a double-sealed polyester bottle for laboratory use. The cap assembly is screwed to the bottle body to form a first seal, while the compression of the elastic component during screwing pushes the sealing component together to form a second seal. This double-sealing design significantly improves sealing performance and effectively prevents leakage. The bottle body features a drainage channel for easy liquid pouring. The overall structure enhances safety and convenience, making it suitable for laboratory settings with high sealing requirements. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-4 The present invention provides a laboratory double-shrink polyester bottle, comprising: a bottle body 1, a cap assembly 2, and an external thread 3 on the outer wall of the bottle mouth of the bottle body 1. It also includes: vertical strip grooves 4 formed on the inner walls of both sides of the bottle body 1, elastic components 5 installed on the inner walls of both strip grooves 4, and a sealing component 6 rotatably installed on the outer wall of the opposite side of the two elastic components 5. Support plates 7 are installed on the inner walls of both sides of the bottle body 1, and a drainage groove 8 is formed on the inner wall of the bottle mouth side of the bottle body 1.

[0020] It should be noted that: the bottle body 1, as the main body, has an external thread 3 on the outer wall of its mouth that provides a screw base for the cap assembly 2; when the cap assembly 2 is screwed onto the mouth of the bottle body 1 through the external thread 3, the cap assembly 2 presses against the bottle body 1 to form the first seal; at the same time, during the screwing process, the cap assembly 2 compresses the elastic components 5 in the strip grooves 4 on both sides of the inner wall of the bottle body 1 to contract, and the elastic components 5 push the sealing components 6 to approach and merge with each other along the gap between the support plate 7 and the inner wall of the top of the bottle body 1, forming the second seal; the drainage groove 8 facilitates the pouring out of the liquid in the bottle body 1, thus achieving the double tightening and sealing function as a whole.

[0021] In a preferred embodiment, the cap assembly 2 includes a cap body 201, a sealing ring 202 adhered to the inner top wall of the cap body 201, and a pressure ring 203 mounted on the inner top wall of the cap body 201.

[0022] It should be noted that: the cap body 201 in the cap assembly 2 is the main structure. When the cap body 201 is screwed to the bottle mouth of the bottle body 1, the sealing ring 202 on its top inner wall will be squeezed between the cap body 201 and the bottle mouth of the bottle body 1, which will enhance the tightness of the first seal. During the screwing process of the cap body 201, the pressure ring 203 on the top inner wall will directly contact and press the elastic component 5, providing force for the contraction of the elastic component 5, thereby driving the sealing component 6 to achieve the second seal.

[0023] In a preferred embodiment, the inner wall of the cover 201 has a threaded groove, and the threaded groove is adapted to the external thread 3.

[0024] It should be noted here that the threaded groove on the inner wall of the cap 201 is adapted to the external thread 3 on the outer wall of the bottle mouth of the bottle body 1. The cap 201 and the bottle body 1 are firmly screwed together through the thread engagement, ensuring that the cap assembly 2 can be tightly pressed onto the bottle body 1, which is the structural basis of the first layer of sealing. At the same time, the axial force generated by the thread engagement provides a stable power transmission path for the pressure ring 203 to compress the elastic component 5, ensuring the triggering of the second layer of sealing.

[0025] In a preferred embodiment, the elastic component 5 includes a fixed rod 501, a spring 502 sleeved on the outside of the fixed rod 501, and a slider 503.

[0026] It should be noted here that in the elastic assembly 5, the fixed rod 501 provides installation and movement guidance for the spring 502 and the slider 503; when the pressure ring 203 of the cap assembly 2 presses the slider 503, the slider 503 slides along the fixed rod 501 and compresses the spring 502. The elastic force of the spring 502 reacts to the slider 503, pushing the sealing assembly 6 connected to it closer to each other, providing power for the second seal.

[0027] In a preferred embodiment, the sealing assembly 6 includes a traction rod 601, a semi-circular plate 602 rotatably connected to one end of the bottom of the traction rod 601, and a sealing strip 603 adhered to the outer wall of one side of the semi-circular plate 602.

[0028] It should be noted here that: in the sealing assembly 6, the traction rod 601 connects the slider 503 of the elastic assembly 5 and the semi-circular plate 602, and transmits the movement of the slider 503 to the semi-circular plate 602; when the elastic assembly 5 pushes, the two semi-circular plates 602 slide along the gap and move closer to each other and merge, and the sealing strips 603 on their outer walls are in close contact, forming a second seal and enhancing the overall sealing performance.

[0029] In a preferred embodiment, a gap is left between the support plate 7 and the inner wall of the top of the bottle body 1, and the semi-circular plate 602 forms a sliding fit with the gap.

[0030] It should be noted that the gap between the support plate 7 and the inner wall of the top of the bottle body 1 provides a sliding track for the semicircular plate 602, ensuring that the semicircular plate 602 can slide stably and accurately under the drive of the traction rod 601; the sliding fit design ensures that the two semicircular plates 602 can be smoothly merged, so that the sealing strip 603 can effectively contact, which is the structural guarantee for the realization of the second seal.

[0031] Working principle:

[0032] First layer of sealing: the threaded seal between the cap assembly and the bottle body.

[0033] The inner wall of the cap 201 of the bottle cap assembly 2 has a threaded groove that matches the external thread 3 on the outer wall of the bottle mouth of the bottle body 1. The cap 201 and the bottle body 1 are securely screwed together through thread engagement.

[0034] During the screwing process, the sealing ring 202 on the inner wall of the top of the cap 201 is squeezed between the cap 201 and the bottle mouth of the bottle body 1, forming a tight fit, preventing liquid or gas from leaking through the gap between the bottle mouth and the cap, thus forming the first layer of seal.

[0035] Second seal: The elastic component drives the closing component to achieve a tight seal.

[0036] During the screwing process of the cap body 201, the pressure ring 203 of the bottle cap assembly 2 moves downward with the cap body and presses the elastic component 5 in the strip groove 4 on both sides of the bottle body 1.

[0037] When the slider 503 in the elastic component 5 is subjected to the pressure of the pressure ring 203, it slides downward along the fixed rod 501, while compressing the spring 502 sleeved outside the fixed rod 501, and the spring 502 generates a reverse elastic force.

[0038] The movement of slider 503 is transmitted to semicircular plate 602 through traction rod 601 of tight-fitting component 6. Due to the sliding fit between semicircular plate 602 and support plate 7 and inner wall of top of bottle 1, the two semicircular plates 602 approach each other and merge under the action of traction force.

[0039] After merging, the sealing strip 603 on one side of the outer wall of the semi-circular plate 602 comes into close contact, forming a closed barrier to further prevent the leakage of substances inside the bottle, thus constituting a second seal.

[0040] Auxiliary function: The role of the drainage channel

[0041] The drainage groove 8 on the inner wall of one side of the bottle opening provides guidance for liquid pouring, reducing residue and spillage during pouring and improving ease of use.

[0042] In summary, this polyester bottle achieves high sealing performance through a dual structure of "threaded seal + elastic drive closure seal," making it suitable for laboratory settings with high sealing requirements.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
