Description

  The present invention relates to a dispensing device such as an ejection device, and more particularly to a device used to dispense liquid contained in a container. The invention further relates to a packaging comprising such a delivery device.

  For example, various types of packaging for storing liquids such as perfume are known. Such packaging often has a device for dispensing liquid. In general, however, such delivery devices are not protected from unintended operation. Therefore, most delivery devices are provided with an additional cover.

  Some dispensing devices are protected against unintentional actuation by additional locking components. However, such locking parts are often lost because they are usually attached to the dispensing device so that they can be removed.

  There are also dispensing devices with lockable rotary actuators. This type of lockable rotary actuator is primarily intended for use in cream delivery and is therefore rarely used for liquid delivery.

  There are also dispensing devices with operating levers. However, such a lever is not designed to lock the delivery device.

  Further conventional dispensing devices for dispensing liquids have been proposed, for example, in the following documents.

  Patent Document 1, Patent Document 2, and Patent Document 3 disclose a feeding device provided with a lever for reducing a push force necessary for operation. However, the device described in any document cannot hide the nozzle or lock the device.

  Patent Document 4 discloses a packaging including a lever capable of hiding a nozzle. However, this lever rotation is not used to operate the pump.

  Patent Document 5 discloses a packaging including a lever capable of hiding a nozzle. In this packaging, the pump is operated by lifting the lever, and the lever swing angle is 90 degrees. Therefore, to operate the pump, it is necessary to operate the lever in a direction away from the bottle and thus in a non-ergonomic manner.

  The object of the present invention is to provide a device used to dispense liquids and a packaging comprising such a device, which has been improved to reduce or eliminate the above drawbacks. In particular, an object of the present invention is to provide a novel delivery device that can prevent unintended delivery of liquid.

  To achieve this object, the present invention provides a dispensing device that is attached to a container containing a liquid and used to dispense the liquid in the container to the outside. According to the invention, the delivery device is a pump comprising a pump body and a pump head displaceable relative to the pump body, the pump being attached to the container, the pump head comprising a nozzle The pump can function to deliver the liquid in the container from the nozzle by pushing the pump head, the pump, a cover member covering at least the pump head, and an operation coupled to the cover member so as to be swingable An operation member capable of acting on the pump head. The cover member is formed with a slit for allowing the operation member to access the pump head. In the non-use position of the operation member, the nozzle is hidden, and the operation member is swung by a predetermined angle from the non-use position, so that at least a part of the operation member is in the use position in the slit. In this use position, it is possible to push in the pump head using the operation member.

  According to the present invention, the operation member constituting the delivery device can play two roles. First, the operation member can serve to protect the nozzle from external dust and dirt when the dispensing device is not used. Secondly, the operating member can function as a lever for operating the pump by applying force to the pump head when the delivery device is used. In particular, according to the invention, the operating member is accessible to the pump head after it has passed through the slit in the cover member, thus ensuring unintentional pump operation and thus unintentional liquid delivery. Can be prevented. Furthermore, according to the present invention, such a function can be realized with a small number of components.

  According to an embodiment of the present invention, the delivery device may be configured such that the operating member can be unlocked by pushing the operating member inwardly.

  According to an embodiment of the present invention, the slit may be formed on the upper surface of the cover member. In this case, since the operation member is pushed down to the container side to which the pump is attached at the time of use, the operation method is excellent in ergonomics.

  According to an embodiment of the present invention, the width of the slit may be smaller than the width of a human finger.

  According to an embodiment of the present invention, the swing angle of the operating member from the non-use position to the use position may be about 270 degrees.

  According to an embodiment of the present invention, the length of the operating member is greater than the length of the slit of the cover member, so that a portion of the operating member does not have to pass through the slit when in use.

  According to an embodiment of the present invention, in the operating member, the width of the portion that does not pass through the slit during use may be larger than the width of the portion that passes through the slit.

  According to an embodiment of the present invention, the length of the operation member may be substantially the same as the height of the cover member.

  According to an embodiment of the present invention, the nozzle of the delivery device may be fixed in position relative to the cover member, and the nozzle and the pump of the delivery device are fluidly connected by a flexible tube. May be.

  An alternative embodiment of the present invention provides a dispensing device that is attached to a container and used to dispense liquid in the container to the outside. According to this alternative embodiment, the delivery device is a pump comprising a pump body and a pump head displaceable relative to the pump body, the pump being attached to the container, the pump head comprising a nozzle. The pump is capable of swinging with respect to the pump, a cover member that covers at least the pump head, and a cover member that can function to deliver liquid in the container from the nozzle by pushing the pump head. And an operating member that can act on the pump head. In the non-use position, the operation member forms at least a part of the upper surface of the cover member, and the operation member is swung from the non-use position by a predetermined angle toward the peripheral surface of the cover member. It becomes. The operating member can act on the pump in this use position.

  According to an embodiment of the present invention, an opening may be formed in the operating member. In this case, in the use position, the nozzle may be exposed to the outside through the opening of the operating member.

  According to an embodiment of the present invention, the operation member and the cover member may be molded using a plastic material as an integral member.

  The present invention further includes the above-described delivery device, and a container in which a liquid is accommodated, and the container to which the delivery device is attached so that the internal space and the delivery device are fluidly connected. Provide packaging to do.

  The invention may be better understood by reading the following description of non-limiting and exemplary embodiments thereof, with reference to the accompanying drawings.

FIG. 6 is a perspective view of a packaging according to a further alternative embodiment of the present invention. FIG. 9 is a schematic cross-sectional view of the packaging of FIG. FIG. 9 is a cross-sectional view showing a state where the packaging operation member of FIG. 8 is swung to a use position. It is sectional drawing which shows the state which act | operated the delivery device by further swinging the operation member, and delivered the liquid in a container.

  FIG. 1 to FIG. 5 show an embodiment of a delivery device according to the present invention and a packaging including the delivery device. The packaging 1 shown in FIGS. 1 to 5 includes a container 10 in which a liquid, e.g. perfume, is accommodated in its internal space, and a dispensing device 20 that can function to dispense the liquid in the container 10 to the outside. Is included. The container 10 may be, for example, a plastic or glass bottle. In this embodiment, the dispensing device 20 is attached to the container 10, for example by screwing.

  As shown in FIG. 2, the dispensing device 20 of the present embodiment includes a pump 22 attached to the container 10, a cover member 30, and an operation member 40. The pump 22 includes a pump main body 24 and a pump head 26 that can be displaced in the vertical direction with respect to the pump main body 24. The pump body 24 includes a tube 22a, and the internal space of the container 10 and the delivery device 20 are fluidly connected via the tube 22a. Further, the pump body 24 includes a skirt 24b. The skirt 24b has a thread on the inner peripheral surface. With the pump 22 attached to the container 10, the thread of the skirt 24b engages the thread of the neck 10a of the container 10. As a result, the pump body 24 is positioned and fixed while being inserted into the opening of the neck 10a of the container 10.

  The pump head 26 includes a nozzle 28 for supplying liquid to the outside. As will be described later, the pump 22 can function to deliver the liquid in the container 10 from the nozzle 28 by pushing the pump head 26 downward. Since such a pump 22 can be a known pump, the structure of the pump 22 itself will not be described in detail.

  The cover member 30 is formed in a substantially cylindrical shape, and has an upper surface and an outer peripheral surface. The cover member 30 covers almost the entire pump 22 in the present embodiment. An operation member 40 that can act on the pump head 26 is connected to the cover member 30 using a pin 41 so as to be swingable. Therefore, in this embodiment, the operation member 40 is realized as a “flip top lever”.

On the upper surface of the cover member 30, a slit 42 for allowing the operation member 40 to access the pump head 26 is formed. The width W ₁ (FIG. 1) of the slit 42 is smaller than the width of a human finger, for example, several millimeters to 1 cm.

  As can be seen from FIG. 4 showing the state in which the operating member 40 is swung upward, the cover member 30 includes a notch 32 for exposing the nozzle 28 to the outside. In the non-use position shown in FIG. 1, the operation member 40 fits into the notch 32 of the cover member 30, thereby forming a part of the outer peripheral surface of the cover member 30. Therefore, the operation member 40 can cover the nozzle 28 of the pump 22 in the non-use position. In the present embodiment, the operation member 40 can be locked so that it cannot be rotated in its non-use position. Further, the operation member 40 can be unlocked by pushing the operation member 40 inward as shown in FIG. Although not shown in detail, such a lock / unlock mechanism of the operation member 40 can be realized by using, for example, a “push-in / push-eject mechanism” well known to those skilled in the art.

As described above, the operation member 40 is pin-coupled to the cover member 30 at the upper end portion thereof, so that the operation member 40 can swing with respect to the cover member 30. In the present embodiment, the angle at which the operation member 40 can swing is approximately 270 degrees, although not limited thereto. The length L ₁ (FIG. 1) of the operation member 40 is substantially the same as the height H (FIG. 1) of the cover member 30. However, the length L ₁ of the operation member 40 is larger than the length L ₂ (FIG. 1) of the slit 42 on the upper surface of the cover member 30, and therefore larger than the diameter of the upper surface of the cover member 30. More particularly, the operating member 40 is a narrow portion 40a, having a width W ₁ slightly smaller width W ₂ than the somewhat longer and the slit 42 than the length L ₂ of the slit 42 (FIG. 4) A narrow portion 40a and a wide portion 40b extending from the narrow portion 40a and having a width W ₃ (FIG. 4) larger than the width W ₂ of the narrow portion 40a are provided. Therefore, the narrow portion 40a of the operation member 40 is accommodated in the slit 42 by swinging the operation member 40 by about 270 degrees from the non-use position shown in FIG. In this use position, the user can push down the pump head 26 using the operation member 40. However, the wide portion 40b of the operation member 40 does not pass through the slit 42 when the operation head 40 is used to push down the pump head 26.

  In the delivery device according to the present embodiment, the operation member 40 has two functions. First, as shown in FIG. 1, when the operation member 40 is in a non-use position that covers the delivery hole of the nozzle 28, that is, in the “OFF” position, the nozzle 28 is protected from external dust and dirt. In addition, advantageously, when not in use, the operation member 40 forms a part of the outer peripheral surface of the cover member 30, so that an aesthetic appearance can be obtained.

  The second function of the operation member 40 is a function that allows the pump 22 to operate more easily than the conventional product by acting as a lever. When the user desires to operate the pump 22 to dispense liquid, the user swings the operation member 40 from the “OFF” position shown in FIG. 1 to the use position, that is, the “ON” position. More specifically, the user first pushes the projection 44 formed on the outer surface of the operation member 40 by one push. As a result, the lock of the operation member 40 is released. Next, the user swings the operation member 40 by about 270 degrees as indicated by an arrow line in FIG.

  By rotating the operating member by about 270 degrees, the operating member 40 is in the “ON” position. In this position, the substantially central portion of the outer surface of the operating member 40 (which forms part of the outer surface of the operating member 40 in the “off” position) abuts the upper surface of the pump head 26.

  As shown in FIG. 5, the user applies a downward force to the operation member 40 in the “ON” position, for example, with the index finger. Then, the operation member 40 swings further downward about the pin 41 (FIG. 2) by a slight angle, and pushes down the pump head 26. As a result, the pump 22 is activated and the liquid in the container 10 is delivered from the nozzle 28 (in this state, the nozzle 28 is no longer hidden by the operating member 40).

  As described above, the operation member 40 protrudes radially outward from the upper surface of the cover member 30 in the “ON” position. When the user operates the pump 22, the user pushes the protruding portion of the operation member 40, that is, the wide portion 40b with a finger. This means that leverage can be used to apply force to the pump head 26. Therefore, according to the present embodiment, not only is the ergonomic efficiency higher than when the pump head 26 is pushed directly with a finger, but the pump 22 can be operated with a smaller force. Furthermore, since the slit 42 formed in the cover member 30 is narrower than the width of the finger, the pump head 26 cannot be pushed down unless the operation member 40 is used. Accordingly, unintended operation of the pump 22 is prevented.

  After dispensing the desired amount of liquid, the user swings it in the opposite direction to the above operation in order to return the operation member 40 to the “OFF” position. When the user finally pushes the operation member 40 that has almost returned to the position before use, the operation member 40 is locked in the “OFF” position. As a result, the packaging is in the state shown in FIG.

  In the above embodiment, the operation member 40 has the same length as the height of the cover member 30. However, it is also possible to extend the operation member 40 so as to protrude from the upper surface of the cover member 30 in a state where it is in the non-use position. In this case, the operation member 40 can be easily raised from the outer peripheral surface of the cover member 30 without employing the push-in / push-eject mechanism or the like.

  So far, the embodiment in which the nozzle is provided so as to be displaceable with respect to the cover member has been described. However, according to another embodiment, the position of the nozzle may be fixed with respect to the cover member. An example of such an embodiment is shown in FIG. In the packaging shown in FIG. 6, the nozzle 28 is separated from the pump head 26 and incorporated in the wall constituting the cover member 30. In this embodiment, the nozzle 28 and the pump head 26 are fluidly connected by a flexible tube.

  Further, according to another embodiment, the operation member and the cover member may be molded as an integral member from a plastic material. An example of such an embodiment is shown in FIG. In this embodiment, the operation member 40 ′ is connected to the cover member 30 ′ via the injection molding hinge 46. Therefore, the operation member 40 ′ can be swung by about 270 degrees as in the embodiment described above.

  8 to 11 show a further alternative embodiment of the dispensing device according to the invention and the packaging comprising it. The packaging 100 shown in FIGS. 8 to 11 also includes a container 110 in which a liquid, for example perfume, is contained in an internal space, and a dispensing device 120 that can function to dispense the liquid in the container 110 to the outside. Contains.

  As shown in FIG. 9, the delivery device 120 includes a pump 122 attached to the container 110, a cover member 130, and an operation member 140. The pump 122 includes a pump body 124 and a pump head 126 that can be displaced in the vertical direction with respect to the pump body 124. The pump body 124 includes a tube 122a, and the internal space of the container 110 and the delivery device 120 are fluidly connected via the tube 122a. The pump head 126 includes a nozzle 128, and the pump 122 can function to dispense liquid in the container 110 from the nozzle 128 by pushing the pump head 126.

  Cover member 130 is formed in a substantially cylindrical shape, and has an upper surface and an outer peripheral surface. The cover member 130 includes a notch 132 for exposing the nozzle 128 to the outside. The operation member 140 that can act on the pump head 126 is connected to the cover member 130 using a pin 141 so as to be swingable. An opening 142 is formed in the operation member 140. As will be described later, when the operation member 140 is in its use position, the nozzle 128 is exposed to the outside through the opening 142 of the operation member 140.

  In this embodiment, unlike the embodiment described above, the operation member 140 forms a part of the upper surface of the cover member 130 in the unused position, as shown in FIG. On the other hand, the operation member 140 is swung from the non-use position by an angle slightly smaller than about 270 degrees as shown by the arrow in FIG. 8. In this use position, the user operates the “trigger”. In this way, a force can be applied to the pump head 126. Such an action in the delivery device 120 of the present embodiment can be realized using, for example, a wedge mechanism.

  More specifically, as can be seen from FIG. 9, in this embodiment, an inclined surface 126 a is formed at the upper end portion of the pump head 126. Further, a wedge member 150 is arranged on the inclined surface 126a. The wedge member 150 can move in a lateral direction with respect to the inclined surface 126a, but the movement in the height direction is limited. The wedge member 150 and the inclined surface 126a of the pump head 126 are in slidable contact with each other. In the use position shown in FIG. 10, the surface of the operation member 140 is in contact with the large end portion 150a of the wedge member 150. When the user further swings the operation member 140 with an index finger, for example, as indicated by the arrow line, the wedge member 150 slightly swings counterclockwise in FIG. This swing pushes the wedge member 150 to the right in FIG. 9, whereby the pump head 126 is pushed down with respect to the pump main body 124 and the pump 122 is activated. As a result, as shown in FIG. 11, the liquid in the container 110 is delivered to the outside through the opening 142 of the operation member 140. When the force applied to the operation member 140 is released after use, the wedge member 150 is returned to the position before use by a spring or the like (not shown).

  So far, various embodiments of the present invention have been described with reference to the drawings. However, the present invention is not limited to these embodiments. Furthermore, the various features of the embodiments described above can be combined with each other unless otherwise possible in principle. Various modifications, changes and other embodiments will be apparent to those skilled in the art. All such modifications, changes and other embodiments are within the scope of the claims.
