Description
Technical Field
[0001] The utility model relates to a packaging bottle, in particular to a packaging bottle used for packaging of niche special liquids, and belongs to the technical field of design and manufacturing of hazardous liquid material packaging parts. Background Art
[0002] There are a variety of packaging bottles designed for liquids of different properties on the market. For example, for leakage protection, the pressure between the bottle cap and the bottle body is generally used to prevent liquid leakage, but this design has a poor leak-proof effect and low leak-proof efficiency. In some special cases, springs or shrapnel are used to increase the contact pressure, but due to the complex structure and high cost, and the springs or shrapnel will corrode when filling highly corrosive liquids, causing leakage and contaminating the packaged solution. In addition, due to the nature of the packaged liquid, some packaging bottles will add pigment masterbatches to meet the requirement that the packaged liquid needs to be protected from light, but for highly corrosive liquids, the pigment will dissolve and penetrate into the liquid, resulting in product quality pollution. The above two situations are unacceptable in some high-end industries.
[0003] Highly permeable liquids are very easy to leak from the gaps in the bottle seals due to their low surface tension. Photolysis requires the bottle to be dark or black, and pigment masterbatches need to be added during the production process. However, the high corrosiveness of the liquid after adding the pigment masterbatch will dissolve the pigment additives, causing quality pollution. Although there are many packaging bottles that can be used for liquid packaging, there are not many ways to package niche special liquids with high permeability, photolysis, and high corrosiveness, which restricts their production. For the above-mentioned special liquids, there is an urgent need to design a packaging bottle to meet the needs of storage and transportation. Utility Model Content

DETAILED DESCRIPTION
[0022] like Figures 1 to 5 The present invention shows a packaging bottle for packaging niche special liquids with good leak-proof effect. The packaging bottle comprises a bottle body and a bottle cap 2. The bottle mouth 3 opened at the top of the bottle body is detachably closed by the bottle cap 2. The packaging bottle also comprises a composite leak-proof structure. The bottle cap 2 is screwed on the bottle mouth 3 opened at the top of the bottle body in cooperation with the composite leak-proof structure. The packaging bottle is prevented from leaking in the process of storage and transfer by the composite leak-proof structure in cooperation with the bottle cap 2 and the bottle mouth 3. The technical solution provided by the present application is based on the existing packaging bottle comprising a bottle body and a bottle cap, and is combined with the assembly feature that the bottle mouth opened at the top of the bottle body is detachably closed by the bottle cap. The packaging bottle of the present application is formed by adding a composite leak-proof structure, and the bottle cap is screwed on the bottle mouth opened at the top of the bottle body in cooperation with the composite leak-proof structure. In this way, the packaging bottle can be prevented from leaking in the process of storage and transfer by the composite leak-proof structure in cooperation with the bottle cap and the bottle mouth. Especially for liquids with small surface tension and strong permeability, it can better ensure the sealing effect and improve the leak-proof performance of the packaging bottle to meet the storage and transportation requirements of niche special liquids.
[0023] Combined with the characteristics that the niche special liquid has photodegradability, in order to avoid photodegradation and deterioration of the liquid properties during storage and transportation, and to be as convenient for manufacturing as possible and reduce liquid leakage caused by collision damage during handling and transfer, the bottle body of this application is an original-color plastic bottle body, and a black photodegradation-proof coating layer 4 is also coated on the outer side wall of the original-color plastic bottle body. The original-color plastic bottle body and the black photodegradation-proof coating layer 4 are integrally formed, and the structure between the bottle body 1 of the bottle and the bottle mouth 3 of the bottle body is set as an arc-shaped transition connection structure 5. Correspondingly, in order to facilitate the locking during the screwing connection between the bottle cap and the bottle mouth, the bottle cap 2 and the bottle mouth 3 of this application are detachably screwed and locked and sealed through a trapezoidal screwing thread 6.
[0024] Correspondingly, as the key structure improved in this application, in order to ensure to the greatest extent that the niche special liquid with a small surface tension does not leak in the packaging bottle, while simplifying its structure as much as possible, and facilitating manufacturing and use, the composite leak-proof structure of this application at least includes a sealing inner ring 7 and a flexible sealing gasket 8. The sealing inner ring 7 is integrally formed on the inner side of the end face of the bottle cap, and the flexible sealing gasket 8 is padded on the inner side of the end face of the bottle cap outside the sealing inner ring. In the closed cap state, the sealing inner ring 7 is squeezed and connected to the inner side wall of the bottle mouth 3, and the flexible sealing gasket 8 is press-connected to the end face of the bottle mouth 3. At this time, at least the projection of the outer side surface of the sealing inner ring 7 in its longitudinal section is a frustum of a cone with a curvature. The diameter of the small end of the frustum-shaped sealing inner ring is smaller than the inner diameter of the bottle mouth 3, and the diameter of the large end of the frustum-shaped sealing inner ring is larger than the inner diameter of the bottle mouth 3. For further improvement, a sealing outer ring 9 is also provided on the inner side of the end face of the bottle cap outside the sealing inner ring 7. The inner diameter of the sealing outer ring 9 is adapted to the outer diameter of the bottle mouth 3, and the flexible sealing gasket 8 is padded on the inner side of the end face of the bottle cap between the sealing inner ring 7 and the sealing outer ring 9. In this way, by sealing the bottle mouth with the two inner and outer sealing rings respectively, and then tightly sealing the end face of the bottle mouth through the flexible sealing gasket 8, the liquid can be prevented from leaking between the bottle mouth and the bottle cap to the greatest extent, achieving the purpose of maximum leak prevention.
[0025] As a niche special liquid, anti-theft after packaging is also an essential requirement. Therefore, the composite anti-leakage structure of this application will of course also include an anti-theft limit lock mechanism, and the packaged bottle after encapsulation indicates the opening state of the bottle cap 2 through the anti-theft limit lock mechanism. Referring to and drawing on the characteristics of the prior art, the anti-theft limit lock mechanism of this application preferably includes at least an upper anti-theft limit ring 10 and an anti-theft ring buckle 11. The upper anti-theft limit ring 10 is arranged in the middle and lower part of the outer wall of the bottle mouth, and the anti-theft ring buckle 11 is arranged at the open end of the bottle cap 2 in a position corresponding to the upper anti-theft limit ring 10; during the first opening process after encapsulation, the anti-theft ring buckle 11 is pulled and broken and opened under the cooperation of the upper anti-theft limit ring 10. Correspondingly, in order to ensure that the bottle cap will not be damaged due to overpressure when covering the bottle cap after opening and using, the anti-theft limit lock mechanism of this application also includes a lower anti-theft limit ring 12, and the lower anti-theft limit ring 12 is arranged on the outer wall of the bottle mouth below the upper anti-theft limit ring 10; during the process of closing the cap, the extreme position of the downward rotation of the bottle mouth 3 is limited by the lower anti-theft limit ring 12.
[0026] In summary, compared with the prior art, the above technical solutions provided by this application also have the following advantages:
[0027] 1. It has a quadruple anti-leakage protection function. Through the inner sealing ring, flexible sealing ring, outer sealing ring, and specialized thread design, it prevents liquid leakage in multiple directions;
[0028] 2. It has a double-layer structure. The inner layer is the original color of the plastic, and the outer layer is dark, which not only prevents the liquid from decomposing under light, but also prevents the liquid quality from being polluted due to the dissolution of pigment additives;
[0029] 3. Through the upper limit ring and lower limit ring of the bottle mouth, it reminds the operator of the tightening degree of the bottle cap, which not only ensures the consistency of the tightening force of the bottle cap, cancels the use of a torque wrench, and improves the operation efficiency. It also prevents the bottle cap from being over-tightened, causing deformation of the bottle cap and resulting in liquid leakage;
[0030] 4. By designing an arc-shaped transition area between the bottle body and the bottle mouth, it prevents the problem of deformation of the packaging bottle when filling volatile liquids at different temperatures.
[0031] The following further illustrates the technical solutions of this application through specific embodiments:
[0032] To achieve the above object, the technical solution adopted by this utility model is:
[0033] 1. The bottle body is of a double-layer structure, with the inner layer being the original color of the plastic and the outer layer being black;
[0034] 2. The transition area between the bottle body and the bottle mouth is arc-shaped;
[0035] 3. The thread of the bottle mouth is a trapezoidal thread;
[0036] 4. An upper anti-theft limit ring is provided below the bottle mouth;
[0037] 5. There is a lower limit ring for the anti-theft ring below the bottle mouth.
[0038] 6. The internal thread of the bottle cap is a trapezoidal thread, which fits tightly with the bottle mouth.
[0039] 7. The bottle cap is provided with a sealing inner ring and a sealing outer ring, which are respectively fitted with the inner wall and the outer wall of the bottle mouth.
[0040] 8. Flexible sealing rings are placed in the grooves of the sealing inner ring and the sealing outer ring.
[0041] 9. The anti-theft ring is connected below the bottle cap, and the anti-theft ring is provided with an internal buckle.
[0042] Embodiment 1
[0043] The present application will be further described in detail in combination with the structure of the packaging bottle.
[0044] 1. By tightly fitting the sealing inner ring with the inner wall of the bottle mouth, it is prevented that the liquid leaks out of the bottle.
[0045] 2. By tightly combining the annular flexible sealing ring with the upper surface of the bottle mouth, it is prevented that the liquid leaks from the inner ring to the outer ring.
[0046] 3. By tightly fitting the sealing outer ring with the outer wall of the bottle mouth, it is prevented that the liquid leaks to the thread part.
[0047] 4. By tightly fitting the external thread of the bottle mouth with the internal thread of the bottle cap, it is prevented that the liquid leaks from the thread part to the outside of the bottle.
[0048] 5. By fixing the upper limit ring with the internal buckle of the anti-theft ring, when the bottle is opened for the first time, the purpose of separating the anti-theft ring from the bottle cap is achieved. At the same time, when the bottle cap is tightened, it prompts the operator that the rotation is in place.
[0049] 6. By the lower limit ring, it further reminds the operator that the rotation is in place, preventing over-tightening and leakage caused by deformation of the bottle cap due to excessive tightening.
