[0006] To achieve the above purpose, the utility model provides the following technical scheme: a wet bottle bottle mouth full sealing bacteria -resistant composite aluminum film sealing structure, which comprises a bottle body, the bottle body top center has a bottle mouth neck which is directly connected with the inner cavity, and the bottle mouth neck is matched with a bottle cap, the inner side top of the bottle cap is provided with a composite aluminum film, the composite aluminum film comprises an uppermost aluminum film, a middle layer of glue layer and a lowermost PET film which is in contact with the top of the bottle mouth neck;

[0007] Wherein, after the bottle cap and the bottle mouth neck are screwed, the PET film and the top of the bottle mouth neck are connected by electromagnetic induction heat melting;

[0008] The bottle cap inner side upper portion further has a film positioning groove corresponding to the composite aluminum film.

[0009] As a preferred scheme of the full-sealing bacteria-blocking composite aluminum film sealing structure of the bottle mouth of the humidification bottle, the bottle cap inner side top further has a ring-shaped positioning groove coaxial with the bottle cap inner side top, and a sealing rubber ring is embedded and installed in the inner side of the ring-shaped positioning groove.

[0010] As a preferred scheme of the full-sealing bacteria-blocking composite aluminum film sealing structure of the bottle mouth of the humidification bottle, the bottle mouth neck further has a limiting ring on the outer periphery lower portion, and the limiting ring top abuts against the bottle cap bottom.

[0011] As a preferred scheme of the full-sealing bacteria-blocking composite aluminum film sealing structure of the bottle mouth of the humidification bottle, the bottle cap outer periphery further has a plurality of evenly distributed anti-skid protrusions.

DETAILED DESCRIPTION

[0018] In order to make the above-mentioned purpose, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model will be described in detail below in combination with the drawings.

[0019] Secondly, the utility model is described in detail in combination with the schematic diagram, and in the detailed description of the utility model embodiments, for the convenience of description, the sectional view of the device structure will be partially enlarged without the general proportion, and the schematic diagram is only an example, which should not limit the scope of the utility model protection here. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in the actual manufacture.

[0020] In order to make the purpose, technical scheme and advantages of the utility model more clear, the embodiments of the utility model will be described in further detail below in combination with the drawings.

[0021] Figs. 1-3 The whole structure schematic diagram of the utility model is shown, please refer to Figs. 1-3The bottle mouth full sealing bacteria blocking composite aluminum film sealing structure of the wet bottle of the embodiment includes a bottle body 100, the bottle body 100 has a bottle mouth neck 110 in the middle of the top, which is directly connected with the inner cavity of the bottle body 100, and a bottle cap 200 which is matched with the bottle mouth neck 110, the inner side of the top of the bottle cap 200 is provided with a composite aluminum film 300, the composite aluminum film 300 includes an aluminum film 310 in the uppermost layer, a glue layer 320 in the middle layer and a PET film 330 in the lowermost layer which is in contact with the top of the bottle mouth neck 110; wherein, after the bottle cap 200 and the bottle mouth neck 110 are screwed tightly, the PET film 330 and the top of the bottle mouth neck 110 are connected by electromagnetic induction heat melting. The inner side of the upper part of the bottle cap 200 also has a film positioning groove 210 corresponding to the composite aluminum film 300, and the diameter of the composite aluminum film 300 is greater than the outer diameter of the bottle mouth neck 110. It can be understood that the original composite aluminum film 300 can be assembled and positioned by the film positioning groove 210, which avoids the composite aluminum film 300 from slipping out of the bottle cap 200 during the operation and movement of the cap, at the same time, the diameter of the composite aluminum film 300 which is greater than the outer diameter of the bottle mouth neck 110 can ensure that the outer ring of the composite aluminum film 300 covers the edge part of the bottle mouth neck 110, which guarantees the sealing effect, and also facilitates the tearing and removing of the composite aluminum film 300 during use. Specifically, in the embodiment, the composite aluminum film 300 is assembled into the bottle cap 200, then the bottle cap 200 and the bottle mouth neck 110 are connected and screwed tightly, so that the composite aluminum film 300 is in contact with the top of the bottle mouth neck 110, and then the composite aluminum film 300 and the bottle mouth neck 110 are completely fused by electromagnetic induction heat melting. During this process, since the melting point of the PET film 330 is low, the PET film 330 will be quickly fused and sealed with the bottle mouth neck 110, and the aluminum film 310 will not be melted, at the same time, the glue layer 320 can ensure that the PET film is more closely attached to the bottle mouth neck 110 and will not be damaged by tightening, and the PET film 330 and the aluminum film 310 both have good airtightness and sealing effect, which can guarantee perfect sealing effect even after the bottle cap 200 is loosened; in summary, the bottle mouth full sealing bacteria blocking composite aluminum film sealing structure of the wet bottle has complete sealing and bacteria blocking effect, which improves the quality of the product and also prevents and reduces the risk of clinical bacterial infection.

[0022] It should be noted that during actual use, after the bottle cap 200 is unscrewed, the medical staff only needs to tear off the composite aluminum film 300 attached to the top of the bottle mouth neck 110, which is simple to operate.

[0023] Further, the inner top of the bottle cap 200 has a coaxial annular positioning groove 220, and a sealing rubber ring 400 is embedded in the annular positioning groove 220, and the bottom of the sealing rubber ring 400 protrudes from the inner top of the bottle cap 200. Since the humidification bottle may not be used up during use, in order to prevent waste, when sealing for the second time, the bottle cap 200 is only screwed into the bottle neck 110, and then the bottle neck 110 is effectively sealed by the abutting cooperation of the sealing rubber ring 400, so as to prevent air leakage or leakage.

[0024] Further, the outer periphery of the bottle neck 110 has a limiting ring 120, and the top of the limiting ring 120 abuts against the bottom of the bottle cap 200. The limiting ring 120 can prevent the bottle cap 200 from being screwed too much and causing difficulty in subsequent opening.

[0025] Further, the outer periphery of the bottle cap 200 has a plurality of evenly distributed anti-skid protrusions 230. The anti-skid protrusions 230 make the operator more smoothly screw and unscrew the bottle cap 200, and play the role of anti-skid and resistance.

[0026] Further, the bottom of the bottle body 100 has an anti-skid bottom support 130. The anti-skid bottom support 130 makes the bottle body 100 more stable when placed, and avoids side slipping.

[0027] Although the utility model has been described above with reference to the embodiments, various improvements can be made and equivalent parts can be replaced without departing from the scope of the utility model. In particular, as long as there is no structural conflict, the features in the embodiments disclosed by the utility model can be combined in any way, and the combinations are not described in this specification due to the consideration of omitting the length and saving resources. Therefore, the utility model is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
