• the invention is related to sprayers, in particular sprayers for distributing pesticides and the like.
• Sprayers of the type described above are known in the art. It is equally known to produce such sprayers with a rotatable spray head, which can thus be turned into a closed and an open position. Especially when hazardous liquids are contained within these sprayers, there is a risk of accidents due to insufficient safety arrangements on these rotatable spray heads. In particular in the area of child safety provisions, existing spray heads of this type, as well as other rotatable portions in other types of devices, are open to improvement.
• Document US5848733 is related to a manually operated pump dispenser, such as a trigger sprayer, having a child resistant nozzle. The pump dispenser is equipped with a locking collar, arranged for locking and unlocking a rotatable nozzle.
• the unlocking operation involves a forward movement of the locking collar, in the spray direction.
• the locking collar is a rather large feature, as it is arranged around the rotatable nozzle. This makes the construction of the dispenser technically complicated.
• a similar mechanisms is described in EP1254722, whereas GB2041339 is related to a locking mechanism for a slidable cover of a spraying device.
• the present invention aims to provide a device, equipped with a rotatable portion, and provided with a safety arrangement.
• the invention aims to provide a spraying device.
• the invention is related to devices as disclosed in the appended claims. It concerns a device comprising a body and a rotatable portion arranged in connection to said body, characterized in that said device further comprises a safety arrangement, comprising a safety portion arranged in connection to said rotatable portion, and a blocking means arranged in connection with the body, for blocking a rotational movement of said safety portion in the ⁇ safe' position of the arrangement, and consequently of said rotatable portion.
• the safety portion is arranged to be releasable from said blocked position by a tilting movement of said safety portion.
• the blocking means comprises a pair of protrusions, with a space in between said protrusions, and wherein said safety portion comprises a frontal lip portion and a rear lip portion, arranged so that said rear lip portion is secured in the space between said protrusions in the safe condition of the arrangement, and further arranged so that said rear lip portion is released from said space by a tilting movement of the safety portion, said movement being actuated by pushing the frontal lip portion towards the side surface of the rotatable body.
• the safety portion is preferably made from an elastic material.
• the safety portion is attached to the rotatable portion in an attachment point. Therefore, the safety portion does not surround the rotatable portion.
• the preferred embodiment of this device is a spraying device wherein the rotatable portion is the rotatable spray head.
• the invention is related to the rotatable portion as such, provided with a safety arrangement according to the invention, and to the spray head as such, provided with said safety arrangement.
• the invention is equally related to a spray head provided with a wall surrounding the spray mouth of said spray head.
• FIG. 1 is representing a side view of the frontal part of a spraying device according to the invention .
• Fig. 2 provides a detail 2-D view of the safety arrangement according to the invention, and of its operation .
• Fig. 3 provides a detail 3-D view of the safety arrangement and of its operation.
• Figure 1 shows the front part of a spraying device, comprising a sprayer body, which may consist of a bottle portion 1, and a top portion 2, in which top portion a pumping arrangement is preferably provided.
• a sprayer of this type may further comprise a trigger/spring arrangement for actuating the pump, or a battery-operated trigger arrangement.
• the pump and trigger arrangement of the sprayer can be produced according to a prior art design.
• the characteristic element of the invention is the safety arrangement 4 with which the spraying device is provided.
• Figures 2a,b,c show the spray head in more detail.
• the spray head comprises a bottom section 6, arranged in contact with the sprayer's top part 2, and a frontal secion 7.
• the spray head shown in the figure has side wall 20 surrounding the actual spray mouth (better visible on figure 3) . The user is thereby prevented from touching the spray mouth directly when he is rotating the spray head.
• the side wall thus offers additional safety against contact with hazardous liquids.
• the invention is also related to a spray head with such a side wall and to a spraying device equipped with such a spray head (without the safety arrangement) .
• the safety arrangement comprises a blocking means in the form of two protruding portions 8, which are attached to the top portion 2 of the sprayer, in the vicinity of the bottom section 6 of the spray head, preferably at the lowest point of that section, as shown in the drawing.
• these protruding elements 8 are of the same material as the spayer' s top part.
• these protrusions are uniform with the sprayer's top part, i.e. formed as one single part with this top part of the sprayer.
• the spray head 3 is equipped with a safety portion 9 attached to the spray head near the head' s bottom section 6 in attachment point 10.
• the safety portion 9 comprises a frontal lip portion 11, and a rear lip portion 12.
• Figure 2a shows the arrangement in the closed (safe) condition. From the attachment point 10, the frontal lip portion 11 extends away from the spray head in an essentially perpendicular direction, is subsequently bent at point 13, and continues to extend at a distance from the spray head's side surface. Preferably, the frontal lip portion 11 extends in an essentially parallel direction to the spray head.
• the rear lip portion 12 is attached to the frontal lip portion 11 at the latter portion's backside (facing away from the spray head) , and extends towards the opposite part of the spray head's bottom section 6. As seen in figure 2, this rear lip portion 12 is secured between the protrusions 8, thereby blocking the rotation of the spray head 3. [0014] As shown in figure 2b, the release of the safety arrangement is actuated by pushing the frontal lip portion 11 towards the spray head's side surface, thereby tilting the safety portion 9, whereby the rear lip portion 12 is lifted out of the space between the protrusions 8, and rotation of the spray head is possible.
• Figure 3 provides a 3-D view of the above described operation.
• Fig. 3a shows the locked (safe) position
• fig. 3b the unlocked position, obtained by pressing the frontal lip portion 11 and rotating the spray head in the direction of the arrow.
• the frontal and rear lip portion preferably form one uniform element 9, produced from a suitable material, preferably polypropylene.
• a suitable material preferably polypropylene.
• an elastic material is used, exhibiting the right elastic properties. These properties, in conjuction with the manner of connecting the safety portion in point 10, must be such that a sufficiently high pressure is required in order to release the safety, so that this operation cannot be actuated by small children.
• the elasticity Upon release of the safety, the elasticity must be such that the safety portion quickly returns to its original position.
• the protrusions 8 preferably have a sloping shape with the larger height near the space in which the safety portion 9 is secured in the safe position. In this way, the spray head may be rotated towards the safe position, and the elastic safety portion 9 will automatically click into the space between the protrusions 8, without requiring the user to manually lift up the rear lip portion.
• a non-elastic material may be used, in which case the safety portion 9 will not automatically return to its original position, but must be manually pushed back to said position. In this case, the attachment at point 10 must be executed in a suitable way, allowing the tilting movement of the safety portion 9, by applying a sufficiently high pressure on the frontal lip.
• Alternatives to the above described preferred embodiment and which fall within the scope of the appended claims, are defined by other specific shapes or orientations of the frontal and rear lip portion, and/or of the protrusions 8.
• a hole or groove may be provided in the surface of the sprayer body, and the safety portion may be secured in that hole or groove.
