Description
Technical Field
[0001] The utility model relates to a structure of a fully plastic oral liquid packaging bottle with high sealing performance, and relates to the technical field of packaging bottles. Background Art
[0002] Oral liquid is a commonly used health care product or medicine in modern people's lives, and the drinking of oral liquid is more convenient than taking tablets.
[0003] The packaging of oral liquid depends on its packaging bottle. Existing oral liquid packaging bottles include glass bottles and fully plastic bottles. Fully plastic bottles are more widely used because they are not easily damaged. However, existing fully plastic oral liquid packaging bottles mostly have a simple integrated packaging bottle structure. When in use, a relatively large external force is required to tear open the seal, or scissors are needed to cut it open, which is rather troublesome. Glass bottles usually adopt a structure that combines a sealing rubber cap and an aluminum cap. After tearing open the aluminum cap, a straw is inserted into the sealing rubber cap for use. However, the tearing part of the aluminum cap is rather sharp, which is likely to cause harm to users, and the sealing rubber cap is likely to fall off after the aluminum cap is torn open, resulting in the leakage of oral liquid. Therefore, a structure of a fully plastic oral liquid packaging bottle with high sealing performance is proposed to solve the problems existing in the prior art. Content of the Utility Model
[0004] The purpose of the utility model is to provide a structure of a fully plastic oral liquid packaging bottle with high sealing performance in view of the defects or deficiencies in the prior art. The fully plastic bottle body is combined with a tearable fully plastic bottle cap, and the bottle mouth is of an inverted conical structure. An inverted conical bottle plug with a limiting layer is inserted at the bottle mouth, which can obtain a better sealing effect. A straw hole is arranged on the bottle plug to cooperate with the bottle cap. After tearing open the bottle cap, a straw can be inserted for use. The overall structure is simple, the sealing effect is good, and it is more convenient to use.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions: It includes a bottle body 1 and a bottle cap 2.

[0021] Explanation of reference numerals: including the bottle body 1, the bottle cap 2, the bottle stopper 3, the bottle mouth 11, the fixing edge 12, the connecting groove 13, the bottle cap tearing piece 21, the tearing layer 22, the connecting edge 23, the straw hole 31, the limiting eaves 32, the sealing plug 211, the tearing part 212. Specific implementation mode
[0022] Refer to Figures 1-6 As shown, the technical solution adopted in this specific implementation mode is: it includes a bottle body 1 and a bottle cap 2. The bottle body 1 is clamped with the bottle cap 2. The top of the bottle body 1 is an inverted conical bottle mouth 11. An inverted conical bottle stopper 3 is arranged inside the bottle mouth 11. Traditional all-plastic bottles are usually of an integrated structure without a specific good sealing structure, while glass bottles are provided with a sealing rubber cap and are fixed by an external aluminum cap to achieve sealing. However, when the aluminum cap is damaged, a gap will occur between the rubber cap and the bottle body, resulting in the loss of the sealing effect, and glass bottles are easily damaged. Therefore, in this embodiment, both the bottle body 1 and the bottle cap 2 are made of high-temperature resistant and environmentally friendly plastic materials, which are safer for storage and use and are not easily damaged. At the same time, an inverted conical bottle mouth structure and an inverted conical bottle stopper structure are adopted. A conical straw hole 31 is arranged in the middle of the bottle stopper 3, and a limiting eaves 32 is arranged on the outer side of the bottom of the bottle stopper 3 to cooperate with the bottom of the bottle mouth 11. After the bottle stopper is inserted into the bottle mouth, the bottom of the bottle mouth will squeeze the bottle stopper upward. However, due to the engagement of the limiting eaves with the bottom of the bottle mouth, the limiting eaves cannot easily pass through the bottom of the bottle mouth, so a downward pulling force will be generated, thereby realizing the sealed connection between the bottle stopper and the bottle mouth;
[0023] When inserting a straw into a traditional glass oral liquid bottle, it is necessary to penetrate the sealing rubber cap with the straw. If a child is using it, it may not be possible to insert the straw smoothly. Therefore, in this embodiment, a conical straw hole is also arranged in the middle of the bottle stopper, which can not only insert the straw without damage for use, but also is a second sealing structure;
[0024] More specifically, a tearable bottle cap tearing piece 21 is arranged in the middle of the bottle cap 2 and is hermetically connected to the bottle stopper 3. The bottle cap tearing piece and the bottle cap are of an integrated structure, but it can be torn for use. When it is not torn, it is hermetically connected to the bottle stopper, and after being torn, a straw can be inserted for use.
[0025] More specifically, a tearing layer 22 is arranged along the bottle cap tearing piece 21 in the middle of the bottle cap 2. The tearing layer 22 and the bottle cap tearing piece 21 are of an integral structure. In order to facilitate the tearing of the bottle cap tearing piece, a circle of tearing layer is arranged. The tearing layer connects the inner wall of the bottle cap and the bottle cap tearing piece. Just pull up the bottle cap tearing piece slightly to tear it, which is convenient to use.
[0026] More specifically, the main body of the bottle cap tearing sheet 21 is circular and located in the middle of the bottle cap 2. One side is rectangular and extends to the side of the bottle cap 2. The rectangular part of the bottle cap tearing sheet 21 is the tearing part 212. The outer side of the tearing part 212 is a stepped structure. The top is flush with the surface of the bottle cap 2, and the outer side is a protruding stepped part that is flush with the side wall of the bottle cap 2. The flushness at each position can prevent the bottle cap tearing sheet from being knocked by the outside, avoiding accidentally tearing it. The lower part of the step is recessed to form an empty groove with the side wall of the bottle cap. When performing the tearing operation of the bottle cap tearing sheet, just put your finger into the empty groove, pinch the stepped part of the tearing part, and pull it up to tear the bottle cap tearing sheet for use.
[0027] More specifically, a sealing plug 211 is arranged at the bottom of the main body of the bottle cap tearing sheet 21. The sealing plug 211 is hermetically connected to the straw hole 31. In this embodiment, the second sealing structure is the sealing plug. Since a connecting edge 23 is arranged at the lower part of the inner wall of the bottle cap 2, and a fixing edge 12 is arranged on the outer side of the top of the bottle mouth 11, a connecting groove 13 is formed between the fixing edge 12 and the bottle body 1. The connecting groove 13 matches the connecting edge 23. When the bottle cap is connected to the bottle mouth, the connecting edge and the fixing edge are engaged, and a certain upward acting force will be generated. The straw hole is a tapered hole with a smaller upper part and a larger lower part. After the sealing plug is inserted, it will be extruded with the inside of the straw hole under the upward acting force, so as to obtain a better sealing effect.
[0028] The working principle of the present utility model: During assembly, the bottle stopper 3 is inserted into the bottle mouth 11, so that the bottom limit eaves 32 of the bottle stopper 2 are clamped to the bottom of the bottle mouth 11. Since both the bottle mouth 11 and the bottle stopper 3 are inverted conical structures, an upward acting force will be generated, so that the bottle stopper 3 is tightly clamped to the bottom of the bottle mouth 11 to achieve a sealed connection. The bottle cap 2 is covered, and the sealing plug 211 is snapped into the straw hole 31. At the same time, since the straw hole 31 is a tapered structure with a smaller upper part and a larger lower part, after the sealing plug 211 is snapped in, an upward acting force will also be obtained under the good clamping action of the connecting edge 23 and the fixing edge 12 to seal the straw hole 211. The double sealing structure can obtain a better sealing effect. When in use, just pull the tearing part 212 and tear the bottle cap tearing sheet 21 upward, so that the sealing plug 211 is separated from the straw hole 31, and the straw can be inserted into the bottle stopper 3 without damaging the bottle stopper 3, making it more convenient to use.
[0029] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model should be covered within the scope of the claims of the present utility model as long as they do not depart from the spirit and scope of the technical solution of the present utility model.
