Title: A receptacle for aerosol-generating articles

Description:
The present invention relates to receptacles for receiving one or more used aerosol-generating articles. The present invention also relates to a kit comprising the receptacle and a container for aerosol-generating articles. 
     After consuming an aerosol-generating article, such as a cigarette, it may be difficult for a user to find a convenient location to dispose of the used article. For example, the user may not be located near to an ashtray or a suitable disposal bin. Therefore, in some circumstances, the user may find it difficult to appropriately dispose of the used article. This problem may be exacerbated when the aerosol-generating article is heated during use without combustion. For example, a number of aerosol-generating systems are known in which an aerosol-generating article, which may be cigarette-like in size and shape, are electrically heated rather than combusted. In such systems, the article may be approximately the same size both before and after use. Therefore, disposal of such articles may be more difficult for a user when compared to a conventional cigarette of which only the filter typically remains after use. 
     Therefore, it would be desirable to provide a convenient manner for a user to manage the disposal of used aerosol-generating articles. 
     According to a first aspect of the present invention there is provided a receptacle for storing one or more used aerosol-generating articles. The receptacle comprises a box portion comprising a closed bottom end and a top end defining a box opening, wherein the bottom end is opposite the top end. The receptacle also comprises a cover portion movable with respect to the box portion between a closed position in which the cover portion covers the box opening and an open position in which the box opening is uncovered. The receptacle further comprises a clip depending from the top end of the box portion and overlying an outer surface of the box portion. 
     As used herein, the term “aerosol-generating article” refers to an article comprising an aerosol-forming substrate that is capable of releasing volatile compounds that can form an aerosol. The aerosol-forming substrate may release volatile compounds when heated. The aerosol-generating article may be a cigarette and the aerosol-forming substrate may comprise a tobacco rod. The aerosol-generating article may be designed for heating within an aerosol-generating device, for example with an electrical heater. 
     The term “underlies” is used herein to mean that a first portion of the receptacle is closer to the interior of the receptacle than an overlapping second portion of the receptacle. That is, the first portion underlies the second portion. Conversely, the term “overlies” can be used to mean that the second portion of the receptacle is closer to the exterior of the receptacle than the first portion. In this case, the second portion overlies the first portion. 
     Advantageously, the receptacle according to the first aspect of the present invention provides a convenient way for a user to store one or more used aerosol-generating articles until the used articles can be disposed of appropriately, for example by emptying the receptacle into a suitable disposal bin. 
     Advantageously, the cover portion retains the one or more used aerosol-generating articles within the box portion when the cover portion is in the closed position. 
     Advantageously, the cover portion is movable with respect to the box portion to permit access to the interior of the box portion when the cover portion is in the open position. When the cover portion is in the open position, one or more used aerosol-generating articles can be at least partially inserted into the box portion through the box opening. When the cover portion is in the open position, one or more used aerosol-generating articles can be removed from the box portion through the box opening. 
     Advantageously, the clip provides a convenient way for a user to store or carry the receptacle. In particular, the receptacle may be attached to a container of aerosol-generating articles using the clip. For example, the receptacle may be clipped onto one of the walls of the container. 
     The clip depends from the top end of the box portion, the top end defining the box opening. Therefore, advantageously, when the clip is used to attach the receptacle to a side wall of a box portion of a container of aerosol-generating articles, the box opening of the receptacle box portion and a box opening of the container box portion are positioned in the same orientation. Advantageously, this may simplify use of both the receptacle and the container. 
     Advantageously, orienting the clip so that it depends from a top end of the box portion may facilitate retention of the receptacle on a container of aerosol-generating articles. For example, to remove the receptacle from the container it may be necessary to open a lid portion of the container and slide the receptacle upwardly to disengage the clip from a side wall of a box portion of the container. Therefore, this arrangement may reduce or minimise unintentional movement of the clip with respect to the container when the container is being used in an upright orientation with the container lid portion at the top. 
     Advantageously, the clip allows reversible attachment of the receptacle to a container of aerosol-generating articles. Therefore, when all of the aerosol-generating articles within the container have been used, the receptacle may be removed and attached to a new container of aerosol-generating articles. 
     Preferably, the clip comprises a top end at the top end of the receptacle box portion, wherein the top end of the clip is non-parallel with the bottom end of the receptacle box portion. Advantageously, this may facilitate attachment of the receptacle to a side wall of a container of aerosol-generating articles. For example, conventional hinged-lid containers for aerosol-generating articles comprise a box portion having side walls with top edges that are non-parallel with the bottom edges of the sidewalls. Therefore, the non-parallel arrangement of the top end of the clip may allow the top end of the clip to rest fully on the top edge of the side wall when the receptacle is attached to the container. Advantageously, this may allow the lid of hinged-lid containers to fully close when the receptacle is attached to the container. 
     The clip may be fixed to the box portion at or around the top end of the clip. 
     Preferably, the clip comprises a first portion overlying the outer surface of the receptacle box portion and a second portion positioned inside the receptacle box portion so that at least a part of the box portion is positioned between the first portion of the clip and the second portion of the clip. Advantageously, this may facilitate securing of the clip to the receptacle box portion. 
     In embodiments in which the clip comprises a top end, preferably the top end is formed at a transition from the first portion of the clip to the second portion of the clip. Preferably, the transition is formed by a bend in the material forming the clip. 
     The second portion of the clip may be shorter than the first portion of the clip. Advantageously, providing the clip with a shorter second portion may reduce or minimise the weight of the receptacle. Advantageously, providing the clip with a longer first portion may increase or maximise the stability of the receptacle when attached to a container of aerosol-generating articles. 
     The second portion of the clip may be longer than the first portion of the clip. Advantageously, providing the clip with a shorter first portion may reduce or minimise the weight of the receptacle. Advantageously, providing the clip with a longer second portion may facilitate securing the clip to the box portion and may increase or maximise the stability of the clip relative to the box portion of the receptacle. 
     The receptacle box portion may have a maximum height extending between the uppermost portion of the top end and the lowermost portion of the closed bottom end. The first portion of the clip may have a maximum length extending between the uppermost portion of the top end and a lowermost portion of a free end distal from the top end. The maximum length of the first portion of the clip is preferably at least about 50 percent of the maximum height of the receptacle box portion, more preferably at least about 60 percent of the maximum height of the receptacle box portion, more preferably at least about 70 percent of the maximum height of the receptacle box portion, more preferably at least about 80 percent of the maximum height of the receptacle box portion. Additionally, or alternatively, the maximum length of the first portion of the clip is preferably less than about 100 percent of the maximum height of the receptacle box portion, more preferably less than about 95 percent of the maximum height of the receptacle box portion, more preferably less than about 90 percent of the maximum height of the receptacle box portion, more preferably less than about 85 percent of the maximum height of the receptacle box portion. 
     At least a part of the receptacle box portion may be received between the first portion of the clip and the second portion of the clip by an interference fit. Advantageously, this may provide a simply and cost-effective way of securing the clip to the receptacle box portion. 
     The second portion of the clip may be secured to an inner surface of the box portion. For example, the second portion of the clip may be adhered to the inner surface of the box portion. 
     The second portion of the clip may be secured to the box portion by overmolding of part of the box portion over the second portion of the clip. 
     Preferably, the clip is formed from a resilient material so that the clip is biased towards the outer surface of the box portion. Advantageously, this may facilitate a secure attachment of the receptacle to a container of aerosol-generating articles. For example, when the receptacle is attached to a wall portion of a container, the biasing of the clip towards the outer surface of the receptacle box portion may retain the wall portion of the container between the clip and the receptacle box portion by an interference fit. 
     The clip may be formed from a plastic. Preferably, the clip is formed from a metal. Suitable metals include, but are not limited to, stainless steel, for example stainless steel grade 1.4301, and stainless spring steel, or combinations thereof. 
     The clip may comprise a first clip positioned on a first side of the receptacle box portion and a second clip provided on a second side of the receptacle box portion, wherein the first side is opposite the second side. Advantageously, this may allow a user to attach the receptacle to either side of a container of aerosol-generating articles. Advantageously, providing the receptacle with two clips may allow a user to attach more than one receptacle to a container of aerosol-generating articles. For example, a first receptacle could be attached to a first side of a container using the first clip and a second receptacle could be attached to a second side of the container using the second clip. Alternatively, a plurality of receptacles could be provided, with some of the receptacles comprising only one clip positioned on the first side of the receptacle and the remaining receptacles comprising only one clip positioned on the second side of the receptacle. In this way, a user may attach a receptacle to each side of the container of aerosol-generating articles without the need for redundant clips on the receptacles. 
     The cover portion may be arranged to slide with respect to the box portion between the closed and open positions. For example, the cover portion may slide within or over one or more guide portions on the box portion. Preferably, the cover portion is arranged to slide in a direction orthogonal to the extent of the clip. Advantageously, this may reduce or eliminate relative movement between the clip and a container to which the receptacle is attached when the cover portion is opened and closed. 
     The cover portion may be a lid portion depending from the top end of the box portion along a hinge line. Preferably, the lid portion is rotatable about the hinge line between the open and closed positions. The hinge line may extend in a direction orthogonal to the extent of the clip. Advantageously, this may reduce or eliminate relative movement between the clip and a container to which the receptacle is attached when the lid portion is opened and closed. 
     The hinge line may be formed by a hinge that is formed separately from the box portion and the lid portion and secured to the box portion and the lid portion. 
     The box portion and the lid portion may be integrally formed from a single material, wherein the hinge line is formed by a line of weakness in the material. 
     Preferably, the hinge line is formed by a hinge comprising one or more first hinge portions formed on the lid portion and one or more second hinge portions formed on the box portion.

     The one or more first hinge portions and the one or more second hinge portions may be mated together by a snap fit. This type of hinge may be known as a snap hinge. 
     Preferably, the lid portion comprises a recess in a bottom edge of the lid portion, wherein a portion of the clip is received within the recess when the lid portion is in the closed position. Advantageously, the recess may prevent obstruction of the lid portion by the clip when the lid portion is moved into the closed position. In embodiments in which the clip comprises a top end, preferably the top end is received within the recess when the lid portion is in the closed position. 
     The receptacle may comprise a flange extending from the top end of the box portion and extending around at least part of the box opening, wherein the lid portion abuts the flange when the lid portion is in the closed position. 
     Advantageously, the flange may provide a tactile indication to a user that the lid portion has been moved completely into the closed position. 
     Advantageously, the flange may reduce or minimise air flow between the lid portion and the box portion when the lid portion is in the closed position. This may reduce or minimise the escape of odour from the receptacle when one or more used aerosol-generating articles are received within the box portion. 
     Preferably, the flange is formed integrally with the box portion. That is, preferably the flange and the box portion are formed from a continuous section of material. 
     The flange may comprise a gap or a recess in which a portion of the clip is positioned. In embodiments in which the clip comprises a top end, the top end may be positioned within the gap or recess.
