Description

Bottle washing device

Technical Field

The present disclosure relates to a bottle washer for cleaning the contents of a bottle.

Background

Bottles are commonly used to contain contents such as liquids, for example, in agricultural production, pesticides are common chemicals, and are typically contained in bottles. When used, the contents need to be poured out of the bottle. In many cases, the contents in the bottle may have a certain viscosity, so that when the contents are poured from the bottle, the contents may adhere to the bottom and inner wall of the bottle to be difficult to pour, thereby causing waste of the product.

The conventional way to solve this problem in the prior art is to make the bottle of non-stick material, or to coat a layer of non-stick material on the bottom and inner wall of the bottle. In this way, when the contents are poured from the bottle, the contents do not adhere to the inner wall of the bottle, thereby enabling the contents to be completely removed from the bottle. However, this method has a drawback in that the production cost of the bottle is high due to the use of the non-stick material.

In certain applications, the contents of the bottle may require further processing, such as dilution, prior to use. In this case, the bottle may be rinsed with a liquid, such as water, to flush out the contents of the bottle. Such a rinsing process is usually carried out manually by the operator, increasing the time and labor costs, and in particular the efficiency and economy of the operation when a large number of bottles need to be treated.

In addition, in many cases, in order to seal the contents in the bottle, a sealing film is generally provided at the mouth of the bottle. Thus, the sealing membrane needs to be removed or pierced first before pouring the contents from the bottle. This further reduces the efficiency of performing the above-described rinsing process.

Disclosure of Invention

It is an object of the present disclosure to provide a bottle washer that overcomes at least one of the deficiencies of the prior art and that is capable of quickly and efficiently cleaning the contents of a bottle.

According to a first aspect of the present disclosure, there is provided a bottle washer for cleaning contents in a bottle, the bottle washer comprising a body defining a longitudinal direction and defining a distal end and a proximal end opposite the distal end along the longitudinal direction; wherein a rinsing cavity and a rinsing hole are formed in the body, the rinsing cavity and the rinsing hole being in fluid communication, wherein a distal end of the body is formed with a blade, the largest dimension of the distal end in a direction perpendicular to the longitudinal direction being equal to or slightly smaller than an inner diameter of a bottle mouth of the bottle, and wherein a rinsing fluid is injected or sprayed into the bottle via the rinsing cavity and the rinsing hole when the bottle washer is cleaning the contents therein, such that the rinsing fluid rinses the bottom and/or inner wall of the bottle.

It can be seen that the bottom and/or inner wall of the bottle can be rinsed by simply extending the body into the bottle and injecting or spraying a rinsing fluid into the bottle via the rinsing chamber and the rinsing aperture, thereby enabling the contents of the bottle to be quickly and efficiently cleaned.

At the same time, such a design may create an opening at the mouth that is substantially close in size to the internal diameter of the mouth, facilitating smooth flow of the contents of the bottle out through the opening.

In addition, for the pesticide bottle with the sealing film at the bottle mouth, the technical scheme integrates the steps of film breaking and flushing, and further saves time and labor cost.

In one embodiment, the bottle washer further comprises a guide conduit comprising an inlet, an outlet, and a guide channel extending between the inlet and the outlet, wherein the guide conduit is fixedly coupled to the body and is in fluid communication with the flush cavity via the outlet.

In one embodiment, the bottle washer further comprises a base plate to which the guide duct is fixed such that a longitudinal direction of the body is substantially perpendicular to the base plate, wherein the base plate is provided with a through hole within which the body is located when seen in the longitudinal direction. The through-hole in the base plate ensures that the contents of the bottle flow out through the through-hole without being obstructed.

In one embodiment, the bottle washer further comprises a sleeve disposed about the through bore, the sleeve extending generally parallel to the longitudinal direction to encircle and be spaced apart from the body. The provision of the sleeve may serve as a guide into which a bottle may be inserted during operation of the bottle washer so that the mouth of the bottle can be substantially aligned with the body to facilitate insertion of the body into the bottle.

In one embodiment, the bottle washer further comprises a base to which the base plate is fixedly coupled, the base being provided with through holes corresponding to the through holes of the base plate. The base may be provided to facilitate placement of a container thereunder for receiving contents flowing from the bottle.

In one embodiment, the guide conduit is provided with a threaded interface at the inlet.

In one embodiment, the cross-sectional area of the flushing port is less than the cross-sectional area of the inlet port such that the pressure of the flushing fluid at the flushing port is greater than the pressure at the inlet port. The design can improve the pressure of the flushing fluid and enhance the flushing effect.

In one embodiment, the irrigation hole is disposed in the distal end and extends substantially parallel to the longitudinal direction.

In one embodiment, the flushing device comprises two of said flushing holes, which are arranged symmetrically with respect to the longitudinal centre line of the body.

According to another aspect of the present disclosure, it also relates to the use of a bottle washer as described above for cleaning pesticide bottles.

According to the bottle cleaning device of the present disclosure, the content in the bottle can be cleaned quickly and efficiently, in the whole operation process, an operator only needs to simply insert the bottle into the sleeve and rotate, and then open the external fluid source, the whole process is very quick and efficient, and especially when cleaning a large batch of bottles, the time and labor cost can be greatly saved.

A bottle washer 1 according to the present disclosure for quickly and efficiently cleaning the contents contained in a bottle will be described below with reference to the accompanying drawings. Particularly advantageous, the bottle washer 1 of the present disclosure is used for agricultural medicine bottles provided with a sealing membrane at the mouth.

Referring to fig. 1, the bottle washer 1 has a body 10, the body 10 defining a longitudinal direction. During use of the bottle washer 1, the body 10 is generally vertically placed such that the longitudinal direction is the vertical direction. Along this longitudinal direction, the body 10 defines a distal end 101 and a proximal end 102 opposite the distal end.

In one embodiment, a blade 103 is formed on the distal end 101 of the body 10, the blade 103 being used to pierce a sealing membrane at the mouth of the vial to form an opening such that the distal end 101 of the body 10 can protrude into the vial through the opening and to facilitate the flow of the contents of the vial out of the opening created by the blade 103.

In one embodiment, the body 10 is formed in a generally elongated shape, with the longitudinal direction being its length direction (in fig. 1, the direction from the distal end 101 to the proximal end 102). For convenience of explanation, as shown in fig. 1, a direction perpendicular to the longitudinal direction of the main body 10 and within the page of fig. 1 is referred to as a width direction, and a direction perpendicular to the page of fig. 1 of the main body 10 is referred to as a thickness direction.

In applications where the mouth of the bottle is provided with a sealing membrane, the bottle washer may form, for example, a blade against the sealing membrane. As shown in fig. 1, the blade 103 is formed on at least a part of the distal end 101, and preferably may be formed on the entire distal end 101, i.e., the blade 103 may extend along the entire distal end 101 in the width direction and the thickness direction. The blades 103 may be formed in a tapered shape to form a sharp end to facilitate piercing of the sealing membrane of the vial.

The body 10 is configured to at least partially protrude into the bottle during operation of the bottle washer 1, i.e. during cleaning of the content of the bottle. In the illustrated embodiment, at least the distal end 101 of the body 10 extends into the bottle during operation of the bottle washer 1. In one embodiment, the entire body 10 may protrude into the vial, i.e., both the distal end 101 and the proximal end 102 protrude into the vial.

In one embodiment, the distal end 101 of the body 10 may be configured such that the maximum dimension of the distal end 101 in a direction perpendicular to the longitudinal direction is substantially equal to or slightly smaller than the inner diameter of the mouth of the bottle to be treated. In a further embodiment, the dimension in a direction other than the maximum dimension may be at least partially smaller than the maximum dimension. For example, in the illustrated embodiment, as shown in fig. 1 and 5, in the case where the body 10 and its distal end 101 have a cross section in a direction perpendicular to the longitudinal direction, for example, of a rhombus shape, the largest dimension thereof in the width direction is substantially equal to or slightly smaller than the inner diameter of the mouth of the bottle to be treated, while the dimensions in the other directions, for example in the thickness direction, are smaller than the dimensions in the width direction. In this case, the distal end 101 can enter into the bottle after the sealing membrane is pierced, and in the case of, for example, rotating the bottle relative to the body 10, the size of the opening formed by the distal end 101 and the blade 103 is enlarged, facilitating the outflow of the content in the bottle.

It is to be understood that "equal to or slightly less than" as described herein means less than or equal to but not more than, wherein "slightly less than" means less than but not much less than, for example, may be 0% to 20% less, further, may be 0% to 10% less, or may be 0% to 5% less.

In operation of the bottle washer 1, the mouth of the bottle is first aligned with the distal end 101 of the body 10, and then the sealing membrane at the mouth of the bottle is pierced with the blades 103, after which the distal end 101 may be extended into the bottle. During this process, the bottle may be rotated relative to the body 10, enlarging the opening formed by the distal end 101 and the blade 103.

As shown in fig. 1, the bottle washer 1 is further provided with a flushing device 20, the flushing device 20 comprising a flushing chamber 201 and a flushing aperture 202. In one embodiment, the irrigation chamber 201 may be formed in the interior of the body 10, for example, between the distal end 101 and the proximal end 102, and the interior of the body 10 may be formed with a cavity that serves as an irrigation chamber 201 for the irrigation device 20. According to embodiments of the present disclosure, the irrigation holes 202 may also be formed in the body 10, and in one embodiment, as shown in fig. 1, the irrigation holes 202 may be formed in the distal end 101 of the body 10. In other embodiments, the rinsing hole 202 may be formed in other portions of the body 10, provided that the rinsing hole 202 is ensured to be in the bottle to facilitate rinsing of the interior of the bottle when the body 10 is inserted into the bottle during operation of the bottle washer 1.

The irrigation chamber 201 is in fluid communication with the irrigation bore 202, and the irrigation chamber 201 is coupled directly or indirectly with an external fluid source. The external fluid source may be a source of flushing gas or a source of flushing liquid, and further may be a source of pressurized fluid, such as a source of pressurized gas or a source of pressurized liquid. Irrigation fluid from an external fluid source is delivered to the irrigation chamber 201 and then to the irrigation holes 202, injected or sprayed into the bottle via the irrigation holes 202. In this way, the flushing device 20 is configured to inject or spray flushing fluid into the bottle via the flushing chamber 201 and the flushing aperture 202 during operation of the bottle washer 1, thereby causing the flushing fluid to flush the bottom and/or the inner walls of the bottle.

As shown in fig. 1, the irrigation hole 202 may be in the form of an elongated hole extending from an irrigation chamber 201 inside the body 10 through the distal end 101 of the body 10 to the outside of the body 10. Those skilled in the art will appreciate that the flushing port 202 may have a variety of suitable shapes and configurations, such as a square port, and the like.

The irrigation holes 202 may have any suitable orientation depending on the requirements and needs of the irrigation. In the illustrated embodiment, the flushing holes 202 extend substantially parallel to the longitudinal direction, i.e. to the length direction of the body 10. It will be appreciated that the flushing holes 202 may also extend at an angle to the longitudinal direction.

The flushing device 20 may have one or more flushing holes 202, for example, in the illustrated embodiment, two flushing holes 202 are shown. However, it will be understood by those skilled in the art that the number of the flushing holes 202 is not limited to two, and may be one or more than two.

In the illustrated embodiment, the two flushing holes 202 are symmetrically arranged about the longitudinal centerline of the body 10. In other embodiments, the flushing holes 202 may take other arrangements, such as different orientations of the flushing holes 202 relative to each other, different shapes or configurations, or non-symmetrical positions on the body 10, etc. Those skilled in the art will appreciate that the relationship of the flushing ports 202 to one another may also be designed according to the requirements of a particular application.

The bottle washer 1 according to the present disclosure may further comprise a guide duct 30, the guide duct 30 being of a substantially tubular structure comprising an inlet 301, an outlet 302 and a guide channel 303 extending between the inlet 301 and the outlet 302. The guide conduit 30 is used to convey the flushing fluid from an external fluid source to the flushing chamber 201 and further to inject or spray it into the bottle for cleaning via the flushing hole 202.

The guide duct 30 is configured to be coupled to the body 10, for example, the guide duct 30 may be fixedly coupled to the body 10. In the illustrated embodiment, the guide duct 30 may be integrally formed with the body 10, in which case, for ease of manufacture, a machining hole 304 may be formed at a location opposite the outlet 302, which machining hole 304 may be closed with a plug after the bottle washer 1 is manufactured.

The guide conduit 30 is configured to be in fluid communication with the flush chamber 201 via the outlet 302. The inlet 301 of the guide conduit 30 is coupled to an external fluid source, whereby flushing fluid from the external fluid source enters the flushing chamber 201 via the inlet 301, the guide channel 303, the outlet 302, and is then injected or sprayed into the bottle via the flushing aperture 202 for a cleaning operation.

The guide tube 30 is provided with a threaded interface 305 at the inlet 301, which threaded interface 305 is externally threaded in the illustrated embodiment to facilitate coupling to an external fluid source via, for example, a hose having mating internal threads.

In one embodiment, the guide duct 30 may be configured to be substantially uniform, i.e., substantially the same in cross-sectional area and cross-sectional shape, from the inlet 301, guide channel 303 to the outlet 302. In other embodiments, the guide conduit 30 may also be configured to be non-uniform, with the cross-sectional areas and cross-sectional shapes of various portions thereof being different from one another to accommodate particular applications having different fluid delivery requirements. A fluid guiding structure may be provided in the guiding channel 303, e.g. on its inner wall, e.g. a spiral shaped protrusion, in order to generate a vortex during delivery of the flushing fluid, enhancing the flushing effect. Those skilled in the art will appreciate that other types of fluid directing structures may be selected as appropriate for the particular application.

In one embodiment, the cross-sectional area of the flushing chamber 201 is larger than the cross-sectional area of the flushing holes 202, in case of a plurality of flushing holes 202 the cross-sectional area of the flushing chamber 201 is larger than the sum of the cross-sectional areas of the individual flushing holes 202. Suitable fluid guiding structures, such as helical protrusions, may also be provided in the flushing chamber 201 and the flushing port 202, e.g. on the inner walls thereof, in order to create fluid movement characteristics, such as turbulence, during injection or spraying, enhancing the flushing effect.

In one embodiment, the cross-sectional area of the flushing holes 202 (in the case of a plurality of flushing holes 202, the sum of the cross-sectional areas of the individual flushing holes 202) may be designed to be smaller than the cross-sectional area where flushing fluid enters the bottle washer 1 from an external fluid source, for example, may be smaller than the cross-sectional area of the passage at the inlet 301 of the guide duct 30. In this way, the pressure of the flushing fluid at the flushing port 202 may be greater than the pressure at the inlet 301 to enhance the flushing effect.

The bottle washer 1 according to the present disclosure may further include a base plate 40, and the base plate 40 may be a plate-shaped member. The substrate 40 is provided with a through hole 401, and the through hole 401 has a substantially circular shape. The guide duct 30 may be provided on the base plate 40, e.g. fixed to the base plate 40, or may even be integrally formed with the base plate 40.

In one embodiment, the guide duct 30 is fixed to the base plate 40 such that a longitudinal direction of the body 10 coupled with the guide duct 30 (e.g., a length direction thereof) is substantially perpendicular to a plane in which the base plate 40 is located. Of course, it will be understood by those skilled in the art that other suitable arrangements may be used, such as the longitudinal direction of the body 10 being not perpendicular to the base plate 40, but rather inclined at an angle.

In one embodiment, the guide duct 30 is fixed to the base plate 40 such that the entire body 10 is within the range of the through-hole 401 when viewed along the longitudinal direction of the body 10 (e.g., the length direction thereof), as shown in fig. 1 and 5. At this time, a part of the guide duct 30 is also within the range of the through hole 401. The through hole 401 is sized such that, after the body 10 is inserted into the bottle, the contents in the bottle can flow out through the through hole 401 without being obstructed.

A sleeve 50 may be provided around the through hole 401 of the base plate 40, the sleeve 50 extending substantially parallel to the longitudinal direction of the body 10 such that the sleeve 50 substantially surrounds the body 10 but is spaced apart from the body 10. The sleeve 50 may serve to guide the bottle, which may be inserted into the sleeve 50 during operation of the bottle washer 1, such that the mouth of the bottle may be generally aligned with the body 10, facilitating the blade 103 of the body 10 to pierce the sealing membrane at the mouth of the bottle, and facilitating the body 10 to extend into the bottle. In this case, the size of the sleeve 50 may be set according to the size of the bottle to be processed.

The bottle washer 1 according to the present disclosure may further include a base 60, and the base 60 may take the form of a stool. Through-hole 601 is provided in base 60 to correspond to through-hole 401 of substrate 40.

The base plate 40 is fixed to the base 60 by, for example, bolts so that the through-holes 601 of the base 60 are aligned with the through-holes 401 of the base plate 40, so that, after the body 10 is inserted into the bottle, the contents in the bottle can flow out through the through-holes 401 and the through-holes 601 without being obstructed.

In one embodiment, as shown in fig. 1 and 3, the sleeve 50 may extend around the through-hole 401 of the substrate 40 on both sides of the substrate 40 such that a portion of the sleeve 50 may pass through the through-hole of the susceptor 60 when the substrate 40 is fixed to the susceptor 60. In this case, when fixing the substrate 40 to the susceptor 60, the substrate 40 and the susceptor 60 can be pre-positioned with respect to each other by passing a portion of the sleeve 50 through the susceptor 60, facilitating alignment of the through-hole 601 on the susceptor 60 with the through-hole 401 of the substrate 40.

The bottle washer 1 according to the present disclosure is simple to operate, and only by inserting the body 10 into the bottle and injecting or spraying the rinsing fluid from the external fluid source into the bottle via the rinsing chamber 201 and the rinsing hole 202, the bottom and/or inner wall of the bottle can be rinsed so as to clean the content in the bottle.

As shown in fig. 2 and 3, a container 70, such as a measuring cup or the like, may be placed under the base 60. During operation of the bottle washer 1, the cap of the bottle is first unscrewed and the bottle is inserted upside down along the sleeve 50, aligning the mouth of the bottle with the body 10. The blades 103 on the distal end 101 of the body 10 then pierce the sealing membrane (if any) at the mouth of the vial, at which point the vial may advantageously be rotated about the body 10 to enlarge the opening at the mouth of the vial. At this time, the content in the bottle flows out of the bottle, passes through-hole 401 of base plate 40 and through-hole 601 of base 60, and flows into container 70 below base 60.

Subsequently, the external fluid source is turned on, and a rinsing fluid is injected or sprayed into the bottle via the guide tube 30 and the rinsing device 20 to rinse the bottom and/or inner wall of the bottle, thereby cleaning the contents remaining in the bottle.

It can be seen that during the entire operation, the operator simply inserts the bottles into the sleeve and rotates them, and then turns on the external fluid source, which is very fast and efficient, and which greatly saves time and labor costs, especially when cleaning large batches of bottles.

In addition, since the sealing film of the bottle mouth can be directly broken in the process of extending the body 10 into the bottle, the step of removing the sealing film of the bottle mouth before cleaning the bottle in the prior art is also omitted. By integrating the membrane rupturing and washing steps together, further time and labor costs are saved. This is particularly advantageous for applications such as cleaning pesticide bottles.

Although exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure.
