Abstract

A toilet bowl rim block dispenser comprises a body (1) for receiving a block of material (14) to be dispensed, and a hook (2) by which the dispenser may be attached to the rim of a toilet bowl. The body (1) is provided with apertures (3) by which water may enter or leave the body (1) when the toilet is flushed. The body comprises a thermoplastic moulding, having a first part which comprises the hook (2) and a first body part (4) which is linked to a second body part (5) by a hinge (6) moulded into the body. Body part (4) carries a single projecting lug terminating in a barb (7). When the first and second body parts are brought together by rotation about hinge (6), the lug and barb (7) engage an aperture (8) in the second body part (5). The body is opened by manually depressing barb (7) so as to disengage it from aperture (8), which is normally prevented by locking means (9), connected to body part (5) by pairs of ribs (10, 11). When no block (14) is present in the dispenser, pressing the lower end (13) of the locking means (9) causes it to move inward, while the upper end (12) moves outward relative to the dispenser, so that downward movement of the barb (7) is no longer restrained, and the barb may be depressed, permitting opening of the body. When a block (14) is present in the dispenser, pressing the lower end (13) of the locking means (9) is inhibited by the presence of the block, and the body may not be opened.

Description

SUPPLIER DEVICE ICO TECHNICAL FIELD The present invention refers to a device for supplying a product to the toilet bowl (sanitary). In particular, it refers to a device adapted to be hooked under the rim of a toilet bowl to interrupt the flow of water as the toilet water is allowed to run, and to deliver the product directly to the toilet bowl. The product placed in such a spout is in the form of a block of solid material, and is sometimes referred to as an edge block, and the spout is sometimes described as an edge block basket.

ICA BACKGROUND TECHNIQUE In the past, edge blocks usually consisted of only fragranced materials. The refillable edge block dispensers were known, but there was no great need to provide these child resistant closures. More recently, brittle blocks containing bleaching agents have been placed on the market, and the desire to ensure that any refillable dispenser is child proof has increased. A number of refillable dispensers have been placed on the market in some countries. Thus, a company sells a whitening edge block in a spout with a liberated stone plug by pressing the end of the suspension hook into the basket. Other refillable dispensers on the market are not childproof reliably. Toilet blocks are products of relatively low cost. They are used in jets that are attached to the edge of toilet bowls. The jets, for reasons of cost, are produced as a simple plastic molding that includes a hook and two body parts joined by a molded hinge. Once the toilet block has been placed in the dispenser by the manufacturer, no one will want access to the toilet block inside the basket. Any need to open the dispenser will only arise in the case of refillable dispensers, when a replacement block will be inserted when the original block has been used. Child-resistant packages based on containers with an articulated cover are known for other products such as medicines. In such containers, the user needs to have access to the container at relatively frequent intervals in order to take the medicine into the container. Articulated containers for medicines in which tabs in a part of the container engage with openings in another part of the container are described, for example, in U.S. Patent 5,346,069. This describes the use of two types of tabs. Both types must be opened before the container itself can be opened. However, the tabs are designed to open sequentially. The ability to open each set of tabs in sequence simplifies the opening procedure, which is desirable for a container that is intended to be opened frequently. Attempts to operate all tabs simultaneously are indicated as counterproductive. The parts that have to be operated manually are all taillables, that is, they are constituted by interacting parts to keep the container in the closed position. U.S. Patent 4,048,050 discloses a child-proof articulated pill box having a pair of tabs that hold the container closed. The box also has means that must be activated before the tabs can be released. However, the medium consists of pivot pins that enter into grooves. The brackets are essentially bayonet-type tabs. The backward movement of the cover is normally prevented by the interaction of the members 35 and 34. When the body is flexed to release these tabs to allow backward movement, the member 35 moves to free the slot 32 thereby allowing the cover is pivoted. This system requires a complex articulation structure. Closing the container requires a first (rotary) movement to bring the top and bottom parts of the container together and a second (translational) movement to cause the tabs to engage to keep the container in a closed position. Such complex closing operation does not seem to be suitable for use in the production of relatively low cost products which are generally produced in automated filling lines. The container does not seem suitable to be manufactured as a one-piece molding.

It has now been found that an improved childproof spout for joining toilet bowls can be produced by a combination of a releasable stone to keep the spout closed and a closing means that must be actuated to allow the releasable stone to be released .

DETAILED DESCRIPTION OF THE INVENTION In accordance with the present invention, a suitable spout for joining the edge of a toilet bowl comprises a body adapted to receive a block of product to be supplied to the toilet bowl and a hook attached to the body. for suspending the body from the edge of a toilet bowl, said body comprising first and second body parts rotatable relatively about a joint and at least one releasable stone which is engaged by rotation of the body parts of an open position to a closed one to maintain said body parts in a closed position, said hook being attached to said first part of the body wherein at least a releasable stone with closing means is provided, said closing means being inclined towards a first position in which acts on the releasable stone to resist the liberation of the stonechat, but is movable by force manual l applied to a second position in which the releasable stone can be released. It is possible to provide a closure means which, when moved to a position in which the releasable stone is released, can be maintained in that position, against the tilting force tending to return it to the first position, until the stone is released. However, young children find the problem of operating two mechanisms separately easier to solve than the problem of operating two mechanisms simultaneously. For this reason, it is preferable to provide a spout in which the stone and the closing means must be operated simultaneously to release the stone. A stone for use in the present invention will generally comprise a coupling member which projects from one part of the body and is sufficiently resilient to mount on a catch member associated with the other body part as the body moves to close, the retainer member retaining the coupling member and thus keeping the body closed until the stone is released. Tabbels used in childproof containers can be classified as direct or indirect tabs. The direct tabs are tabs that open by manipulating the coupling member directly. The indirect tabs are tabs that open by manipulating the body instead of the coupling medium itself. It is preferred to use tabs which are released by compression forces applied to the interior of the body, instead of tension forces applied in directions away from the interior of the body. In other words, it is preferred to open the body by pressing instead of pulling. It is preferred to use direct tabs instead of indirect tabs. The releasable stone can be of the shape of a fin projecting forward from the edge of one part of the body to the other part of the body (when the body is closed) and bearing a part projecting outwards (outwards) in relation to the surface of the adjacent body part) which engages with a retainer member in the other part of the body. The detent member may be an opening that extends through the body part or a depression within the body part. In the case of an indirect tarabilla, if the body is made of material that is elastically deformable under pressure, the part of the body that carries the fins can be deformed by pressing on it adjacent the fins to deform it sufficiently to move the fins inwards ( towards the inside of the body) to uncouple the projections projecting on the fins of the closure members on the other part of the body. Making portions that project sufficiently small and fins rigid enough, the brackets can be made resistant to open by direct pressure in the brackets, to a if the brackets are accessible through openings in the body. Alternatively, the indirect tabs may have fins projecting forward which fall out of the other part of the body, and inwardly directed projections which engage the closure members, v. g. , openings, on the other part of the body. Such tabs will be released by pressing on the part of the body that carries the closure member, instead of the part that carries the fins. The two body parts can be hinged together so that the joint is on one side of the body (the side that carries the hook that is considered to be the top). Preferably the hinge is on the lower side of the body opposite the hook, so that the second part of the body is opened by turning it downwards. The joint may be constituted by coaxial rod portions in a part of the body that engages with coaxial openings in the other part of the body. In this case, it may be possible to produce the two body parts as separate moldings which are linked together before being filled with the material to be stocked. However, it is preferred to make the spout as a one piece molding and for the joint to be what is known as a "live joint" formed by a line of reduced thickness in the molding. As discussed earlier, indirect tabs are tabs that open by exerting pressure on the body instead of on the tabs themselves. The stonechat can be of the shape of a fin projecting forward from the edge of one part of the body to the other part of the body (when the body is closed) and which bears a part projecting outwards (outwards) in relation to the surface of the adjacent body part) which engages with a retainer member on the inner surface of the other part of the body. The detent member allows the projecting part to be mounted on it when the body is closed, but retains the projecting part to keep the body closed. The detent member may be a depression that does not extend through the body to the external surface or may be an opening in the body part. If the body is made of material that is elastically deformable under pressure, the part of the body that carries the fins can be deformed by pressing it adjacent the fins to deform it sufficiently to move the fins inward (toward the interior of the body) to uncouple the portions which project into the fins of the closing members in the other part of the body. When the projecting portions engage with openings in the other part of the body, the projecting portions can be made sufficiently small and the wings sufficiently rigid so that the tabs are resistant to open by direct pressure on the tabs. Alternatively, the indirect tabs may have fins projecting forward which fall out of the other part of the body and inwardly directed projections which engage with depressions or openings in the other part of the body. Such tabs will be released by pressing on the part of the body that carries the openings instead of the part that carries the fins. It may be desirable to provide a depression on the external surface of the part of the body that carries a projecting portion, said depression being adjacent to the stone to facilitate the application of finger pressure on the body part to open the stone. Preferably, the releasable plug is of the shape of a fin carrying projections mounted on the first part of the body (which carries the hook) which interacts with openings in the second part of the body. The tarabillas are preferably provided with means, such as barbs, which make it easier to close the brackets when the body parts are joined, but which resist release unless pressure is applied to the barb or body to release the brackets. Preferably, the dispenser is provided with only one stone. This simplifies the manufacture of the full spout. When the two parts of the body are hinged to one another after a toilet block has been inserted into the open spout, there is only one stone to be coupled. This reduces the risk of producing improperly closed jets using automated filling equipment. The closing means is inclined towards a first position in which it resists the relative movement of the parts of the body to release the stone. Thus, a force must be applied to the closure means to release the closure means and to keep it released simultaneously with the application of force to release the stone. The closure means may be tilted towards the first position as a result of the inhe elasticity of the material forming the body. Preferably, as indicated above, the releasable plug and the closing means are such that they allow the spout to be produced as a molding of a part. The closing means moves preferably between the first and second positions by rotation relative to the part of the body that carries the closing member. The force applied to the closure means to move it to the second position preferably acts towards the interior of the body. The closure means is preferably provided with a block coupling means which engages a toilet block within the spout to prevent release of the closure means while the spout contains a new toilet block. A particularly preferred form of the invention comprises a spout suitable for sticking to the edge of a toilet bowl, comprising a body adapted to receive a block of product to be delivered to the toilet bowl and a hook attached to the body to suspend the body of the rim of a toilet bowl, said dispenser is a one-piece molding formed of elastic thermoplastic polymer and having a direct tapping cap comprising a fin mounted on the first part of the body, said plug carrying a spike which, in the closed position of the body, extends outwardly through an opening in the second part of the body, and a closing means, the closing means which is hinged to the second part of the body so that it is inclined by the elasticity of the polymer molded to a first (normal) position, the closure means having a first portion and a second portion on either side of the joint, so that in the first position the first portion engages the flap of the stone to prevent the action of the stone, but can be rotated around the joint by pressing in the closing means below the joint to rotate the upper portion of the closing means out coupling with the fin, and wherein the lower portion of the closure member engages a sanitary block within the body to prevent rotation of the closure member when a new sanitary block is present in the body.

BRIEF DESCRIPTION OF THE DIAMETERS The invention will now be described with reference to the accompanying drawings in which: Figure 1 is a perspective view of a dispenser according to the invention in the closed position; Figure 2 is a cross-section through the spout of Figure 1 showing a new sanitary block in position at the spout; Figure 3 is a cross section of the nozzle of Figure 1 without a sanitary block showing the closure means moved to a position to allow the stone to be released; Figure 4 is a cross-section of the jet of Figure 1 without a sanitary block showing the cap in the released position, and Figure 5 is a cross section of the jet of Figure 1 in the open position.

BEST MODE FOR CARRYING OUT THE INVENTION As can be seen from Figure 1, the jet comprises a body (1) to receive a block of material (shown in Figure 2) and a hook (2) in a conventional manner attached to its upper end by which the spout can be glued to the edge of a toilet bowl. The body (1) is provided with openings (3) by means of which the water can enter and / or leave the body (1) when the water is allowed to run in the toilet bowl. The spout is a simple molding made of a suitable thermoplastic material. The molding comprises a first part which comprises the hook (2) and a first part of the body (4) which is linked to a second part comprising a second part of the body (5) by means of a hinge (6) molded in the body. body (see Figures 2 to 5). The part of the body (4) has a single projecting fin which ends in a spike (7). When the first and second parts of the body are joined by rotation around the joint (6), the fins and tines in the body part (4) engage with an opening (8) in the body part (5) (this is you can see better in Figures 4 and 5). The body parts and projections are flexible enough to allow the tines to enter the corresponding openings to keep the body (1) closed. The tines, however, resist the separation of the two body parts (4) and (5). In order to open the body (1), it is necessary to manually press the tine (7) so that it is released from the opening (8). However, the tightness of the tine (7) to release the stone is normally avoided by a closing means (9). The closure means is connected to the body part (5) by pairs of ribs (10, 1 1) on either side of the closure means, but is free at its upper and lower ends. The upper end (12) of the closure means (9) when in its normal position engages with the underside of the tine (7) to prevent it from being depressed. The closure means may be caused to rotate relative to the rest of the body part (5) because the ribs (10, 11) are sufficiently flexible to act together as a hinge, but sufficiently elastic to resist permanent deformation and provide restoring force that tilts the closure means back to its normal position in which it prevents the oppression of the tine. When there is no block present in the spout, a manual force at the lower end of the closure means causes the lower end (13) to move inward and the upper end to move outward relative to the spout so that the movement towards Down the barb (7) is no longer restricted by the closing means (see Figure 3). Although the lower end of the closure means is still pressed inward, it is then possible to press the tine (7) (see Figure 4) and open the body (see Figure 5). If the spout contains a new sanitary block (14) (see Figure 2), then it will not be possible to move the lower end of the closure means inward because the lower end of the closure means will couple with the sanitary block before the upper end is left. Free of the pick (7). This is a significant aspect of additional security. When the body is closed by jointing the body parts together the flap will be deformed so that the prong (7) will slide under the body part (5) until it is inside the opening (8) when the force on the flap is released so that the prong moves in engagement with the opening (8). If the tine (7) meets the upper end of the closing means (9), it will be able to slide on the closing means until it is coupled with the opening (8), so that the closing of the body is not prevented. This is desirable both for the replacement by the consumer of a used sanitary block, as well as for the manufacturer of the full original dispenser. However, once the prong has engaged with the opening, the prong can not be slid with respect to the part of the body (5) and the closing means (9) until the closing means has been moved to a position in which it is free of the pick.
