Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a fluid bottle and a sprayer. Background Technology

[0002] Commercially available liquid medicine bottles typically have vented filters. When drawing liquid medicine from the bottle, the internal volume remains constant, allowing air to enter through these vents. This can lead to inaccurate dosage due to air being drawn in during the process, and a significant amount of medicine remains inside after drawing, resulting in waste. Furthermore, these bottles are unsuitable for medicines that cannot be exposed to air for extended periods. Therefore, avoiding these shortcomings of liquid medicine bottles is a technical problem that requires the expertise of those skilled in the art to solve. Utility Model Content

[0003] To solve the above-mentioned technical problems, this application provides a fluid bottle, which includes a bottle body, a shrinkable bag body, and a sealing assembly. The bag body is located inside the bottle body. The top of the bag body and the bottle body are respectively provided with a bag opening and a bottle opening. The bag opening and the bottle opening are connected together. The sealing assembly seals the bag opening. The inside of the bag body is used to contain fluid. The bottle wall of the bottle body is provided with a first vent hole that connects the inside and outside of the bottle body.

[0004] In one embodiment of the fluid bottle, the sealing assembly includes a sealing cap and a sealing gasket. The sealing cap includes a cap body, an inner insert, and an outer sleeve. The outer sleeve surrounds the outer side of the inner insert. The cap body is connected between the top end of the outer sleeve and the top end of the inner insert. A locking portion is provided on the inner side of the outer sleeve. The cap body is located on the top side of the bottle mouth. The sealing gasket is pressed against the top surface of the cap body and the bottle mouth. The outer sleeve is fitted onto the outer side of the bottle mouth and is engaged with the bottle mouth through the locking portion. The inner insert is inserted into the bottle mouth. The bottle mouth is pressed against the outer side of the inner insert and the inner side of the bottle mouth.

[0005] In one embodiment of the fluid bottle, the insert includes a sleeve portion and an end cap portion that closes the bottom port of the sleeve portion. The outer edge of the end cap portion is connected to the sleeve portion via an annular connecting portion. The annular connecting portion includes a minor arc connecting section and a major arc connecting section. The thickness of at least a portion of the major arc connecting section is less than the thickness of the minor arc connecting section, so that the end cap portion can detach from the sleeve portion and fold down at the major arc connecting section under the action of external force. The folded-down end cap portion can remain connected to the sleeve portion through the minor arc connecting section.

[0006] In one embodiment of the fluid bottle, the inner side of the sleeve portion is provided with an inwardly protruding annular ridge, which is used to abut against a pipe fitting passing through the sleeve portion to achieve a seal between the pipe fitting and the sleeve portion.

[0007] In one embodiment of the fluid bottle, the fluid bottle includes a first diaphragm connected to the sealing cap, the first diaphragm closing the top end port of the sleeve portion.

[0008] In one embodiment of the fluid bottle, an annular rib protruding toward the sealing gasket is provided on the top surface of the bottle mouth.

[0009] In one embodiment of the fluid bottle, the fluid bottle includes a cover, the sealing assembly and the bottle body are both located inside the cover, the top of the cover is provided with an inwardly bent riveting part, the riveting part prevents the sealing assembly and the bottle body from being dislodged from inside the cover, and the cover is provided with a second vent hole communicating between the inside and outside of the cover.

[0010] In one embodiment of the fluid bottle, the fluid bottle includes a second diaphragm connected to the housing and sealing the second vent.

[0011] In one embodiment of the fluid bottle, the casing includes a bottom wall and a side wall surrounding the outside of the bottom wall. The side wall has a positioning protrusion that protrudes into the casing and abuts against the sealing assembly or the bottle body.

[0012] In one embodiment of the fluid bottle, the casing is provided with a snap-fit ​​part, through which the fluid bottle can be snapped into a target installation position.

[0013] This application also provides a sprayer assembly comprising a sprayer and a fluid bottle as described in any of the preceding claims, the sprayer including a tubing inserted inside the bag to draw fluid from inside the bag.

[0014] In one embodiment of the sprayer assembly, the sprayer includes a lower housing having a puncture portion.

[0015] The fluid bottle provided in this application has no vent holes on the bag body. When fluid is drawn from inside the bag body, the bag body shrinks as the fluid decreases, causing the volume of the bag body to decrease as the fluid decreases. In this way, no air will enter the inside of the bag body during the liquid drawing process. Therefore, it overcomes the shortcomings of inaccurate drawing volume, excessive fluid residue, and unsuitability for fluids that cannot be in contact with air for a long time caused by air entering the fluid storage area. It can ensure the accuracy of the drawing volume, reduce fluid waste, and be applicable to more types of fluids. Attached Figure Description

[0026] This application provides a fluid bottle and a sprayer assembly. To enable those skilled in the art to better understand the technical solution of this application, the technical solution of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-4As shown, the fluid bottle 100 provided in this application includes at least a bottle body 101, a shrinkable bag body 102, and a sealing assembly. Specifically, the bag body 102 may be made of a flexible material to achieve shrinkability.

[0028] The bag body 102 is located inside the bottle body 101. The top of the bag body 102 and the bottle body 101 are respectively provided with a bag opening 1021 and a bottle opening 1011. The bag opening 1021 and the bottle opening 1011 are connected together. Exemplarily, the bag body 102 and the bottle body 101 can be blow-molded, during which the bag opening 1021 and the bottle opening 1011 of the bag body 102 naturally combine together.

[0029] The sealing assembly seals the bag opening 1021. The interior of the bag body 102 is used to contain fluid. The bottle body 101 has a first vent 1014 on its wall, connecting the inside and outside of the bottle body 101. In the figure, the bottle body 101 includes a bottom wall 1013 and a side wall 1012 surrounding the bottom wall 1013. The first vent 1014 is provided on the bottom wall 1013, which facilitates the processing of the first vent 1014. Alternatively, the first vent 1014 can also be provided on the side wall 1012.

[0030] When fluid is drawn from the bag 102 of the fluid bottle, the bag 102 contracts as the fluid volume decreases, thus reducing its volume. This prevents air from entering the bag 102 during the liquid drawing process, overcoming the drawbacks of inaccurate volume, excessive fluid residue, and unsuitability for fluids that cannot be in prolonged contact with air, which are caused by air entering the fluid storage area. It ensures accurate volume drawing, reduces fluid waste, and is suitable for holding a wider variety of fluids. Furthermore, during liquid drawing, air enters the bottle 101 through the first vent 1014, balancing the pressure changes inside the bottle 101 caused by the contraction of the bag 102.

[0031] In some embodiments, such as Figure 5 As shown, the sealing assembly includes a sealing cap 103 and a sealing gasket 104. The sealing cap 103 includes a cap body 1031, an inner insert 1032, and an outer sleeve 1033. The outer sleeve 1033 surrounds the outer side of the inner insert 1032. The cap body 1031 is connected between the top end of the outer sleeve 1033 and the top end of the inner insert 1032. A locking portion 1033a is provided on the inner side of the outer sleeve 1033. Figure 3As shown, the cap body 1031 is located on the top side of the bottle mouth 1011, and the sealing gasket 104 is pressed between the cap body 1031 and the top surface of the bottle mouth 1011. The outer sleeve 1033 is fitted onto the outside of the bottle mouth 1011 and is engaged with the bottle mouth 1011 through the locking part 1033a. For example, an annular protrusion A can be provided on the outside of the bottle mouth 1011, allowing the locking part 1033a to engage with the bottom side of the annular protrusion A. The inner insert 1032 is inserted into the bottle mouth 1011, and the bag opening 1021 is pressed between the outer side of the inner insert 1032 and the inner side of the bottle mouth 1011. This sealing structure has a good sealing effect and is relatively easy to assemble. Of course, in actual implementation, the sealing structure is not limited to this, as long as it can reliably seal the bag opening 1021.

[0032] In the illustrated embodiment, as Figure 4 As shown, an annular rib B protruding towards the sealing gasket 104 is also provided on the top surface of the bottle mouth 1011. When the sealing gasket 104 is pressed between the cap body 1031 and the top surface of the bottle mouth 1011, the annular rib B serves as the contact part with the sealing gasket 104, so that the sealing gasket 104 can be reliably pressed against by the annular rib B, thereby further improving the sealing effect.

[0033] In some embodiments, such as Figure 6 As shown, the insert 1032 includes a sleeve portion 1032a and an end cap portion 1032b connected to the bottom end of the sleeve portion 1032a, the end cap portion 1032b closing the bottom port of the sleeve portion 1032a. The outer edge of the end cap portion 1032b is connected to the sleeve portion 1032a through an annular connecting portion 1032c. The annular connecting portion 1032c includes a minor arc connecting segment E and a major arc connecting segment D. The major arc connecting segment D is thinned such that at least a portion of the thickness of the major arc connecting segment D is less than the thickness of the minor arc connecting segment E. Specifically, it can be locally thinned to create a local breakage point or thinned overall to make the entire major arc connecting segment D prone to breakage. In this way, as Figure 5 As shown, during the process of inserting the fitting 203 inside the inner body 1032, under the impact of the fitting 203, the end cap 1032b disconnects from the sleeve 1032a at the superior arc connecting section D and folds down. The folded-down end cap 1032b remains connected to the sleeve 1032a through the inferior arc connecting section E, so that the end cap 1032b does not obstruct the passage of the fitting 203. At the same time, the fitting 203 does not fall off the sleeve 1032a after passing through the end cap 1032b, thus preventing the end cap 1032b from falling off and blocking the first vent 1014.

[0034] In some embodiments, such as Figure 5As shown, the inner side of the sleeve portion 1032a is provided with an inwardly protruding annular ridge C, which is used to abut against the pipe 203 that passes through the inner insert 1032 to achieve a seal between the pipe 203 and the sleeve portion 1032a.

[0035] In some embodiments, such as Figure 3 As shown, the fluid bottle includes a first diaphragm 106, which is connected to the sealing cap 103. The first diaphragm 106 seals the top end of the sleeve portion 1032a, thus preventing impurities from entering the interior of the sleeve portion 1032a. Exemplarily, the first diaphragm 106 can be adhered to the top surface of the cap body 1031. It should be noted that the first diaphragm 106 is a very thin membrane structure, allowing the tube 203 to easily pass through it during insertion.

[0036] In some embodiments, such as Figures 1-3 As shown, the fluid bottle is further provided with a cover 105, and the sealing assembly and the bottle body 101 are both located inside the cover 105. When a first diaphragm 106 is provided, the first diaphragm 106 is also located inside the cover 105. The top of the cover 105 is provided with an inwardly bent riveting portion 1051, which prevents the sealing assembly and the bottle body 101 from being dislodged from inside the cover 105. Exemplarily, during assembly, the sealing assembly, the first diaphragm 106 (if provided), and the bottle body 101 can be assembled together to form a pre-assembled body. Then, the pre-assembled body can be inserted into the cover 105 from the top of the shell sidewall 1052. After insertion, the top of the cover 105 can be bent to form the aforementioned riveting portion 1051.

[0037] The material rigidity of the casing 105 is greater than that of the bottle body 101. For example, the casing 105 is made of metal, and the bottle body 101 is made of plastic. Because the material rigidity of the casing 105 is greater than that of the bottle body 101, the casing 105 is less prone to deformation, thereby protecting the bottle body 101 and avoiding the risk of deformation of the bottle body 101 when external force is used during manual assembly of the fluid bottle.

[0038] The cover 105 is provided with a second vent 1054, which connects the inside and outside of the cover 105. Thus, when fluid is drawn from inside the bag 102, air can sequentially pass through the second vent 1054 and the first vent 1014 into the bottle 101, balancing the pressure changes inside the bottle 101 caused by the contraction of the bag 102. In the figure, the cover 105 has a bottom wall 1053 and a side wall 1052 surrounding the bottom wall 1053. The second vent 1054 is located on the bottom wall 1053; alternatively, the second vent 1054 can also be located on the side wall 1052.

[0039] In some embodiments, such as Figure 1 As shown, the side wall 1052 of the shell is provided with a positioning protrusion that protrudes into the cover 105. The positioning protrusion abuts against the bottle body 101 or the sealing assembly, further constraining the relative position of the bottle body 101, the sealing assembly and the cover 105. Figure 1 In the middle, a ring of dot-shaped first positioning protrusions 1052a is provided on the side wall 1052 of the shell, that is, multiple dot-shaped first positioning protrusions 1052a are arranged sequentially at intervals along the circumference. A ring of annular second positioning protrusions 1052b is also provided. The first positioning protrusions 1052a abut against the outer sleeve 1033 of the sealing cap 103, and the second positioning protrusions 1052b abut against the side wall 1012 of the bottle. The two rings of positioning protrusions assist each other, which is more conducive to ensuring the positioning effect.

[0040] In some embodiments, such as Figure 3 As shown, the fluid bottle includes a second diaphragm 107, which is connected to the casing 105 and seals the second vent 1054. The second diaphragm 107 prevents impurities from entering the casing 105 through the second vent 1054. It should be noted that the second diaphragm 107 is a very thin membrane structure; it can be punctured during use.

[0041] In some embodiments, such as Figure 1 As shown, the housing 105 is provided with a snap-fit ​​portion 1052c, which is an annular groove recessed into the housing 105. The fluid bottle can be snapped into the target installation position via the snap-fit ​​portion 1052c. For example, as... Figure 7 As shown, when the fluid bottle is used in conjunction with the sprayer 200, it can be snapped into the inside of the connecting sleeve 2011 of the sprayer 200 via the snap-fit ​​part 1052c.

[0042] like Figure 7 As shown, the sprayer assembly provided in this application includes a sprayer 200 and the aforementioned fluid bottle 100. The sprayer 200 includes a tube 203 inserted into the inside of the bag body 102 to allow liquid to be drawn from inside the bag body 102.

[0043] In some embodiments, such as Figure 7 As shown, the sprayer 200 includes a rotating lifting component 201, which includes a connecting sleeve 2011. The connecting sleeve 2011 is provided with a mating part 2011a. The cover 105 is inserted into the connecting sleeve 2011, and the aforementioned snap-fit ​​part 1052c of the cover 105 is snapped into the aforementioned mating part 2011a of the connecting sleeve 2011.

[0044] In some embodiments, such as Figure 7As shown, the sprayer 200 includes a lower housing 202, which has a puncture part 2021. In use, the lower housing 202 is removed, the fluid bottle 100 is inserted into the sprayer 200, and then the lower housing 202 is reinstalled, so that the puncture part 2021 punctures the second diaphragm 107 of the fluid bottle.

[0045] The above examples illustrate the principles and implementation methods of this application. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
