Definitions
- This disclosure relates to a play apparatus, in particular a base for a play apparatus, e.g. for a tetherball game, such as the well-known tether tennis game Swingball®.
- Play apparatuses for tetherball games are popular, as they allow users to play a ball game in a restricted space without the risk of losing the ball.
- these play apparatuses can also be used as a training apparatus to develop a user's hand-eye co-ordination and reflexes.
- such an apparatus can be used by a single player, for individual practice, or two or more players, optionally in a competitive game.
- tetherball games There are many different types and sizes of play apparatus for tetherball games available, including, for example, tether tennis apparatus and tether football apparatus.
- GB2354018A discloses an example of a base for a tetherball apparatus.
- a movable stand for supporting a pole has a ballast-containing base with a detachable lid with a hole to receive the pole.
- the lid is attached to the base by a two-stage attachment, the first being a tongue and groove formation located around the periphery of the base and lid.
- the second is in the form of two or more locking devices around that base that prevent separation of the tongue and groove arrangement.
- a first aspect of the present disclosure provides a base for a play apparatus, e.g. for a tetherball game.
- the base comprises: a container defining an internal volume and an opening providing access to the internal volume; a removable lid configured to cover the opening; and a securing means operable to secure the lid in place over the opening.
- the securing means comprises a first part and a second part, the first part being fixedly attached to or integrally formed with the container and the second part being fixedly attached to or integrally formed with the lid, the first part and the second part being configured to engage directly with each other to secure the lid in place, in use, when the lid is placed over the opening.
- the action of moving the lid, relative to the container, towards a position at which the lid covers the opening may be sufficient to cause the first part and the second part of the securing means to engage with each other.
- the base may be configured such that a translation of the lid, i.e. linear movement in a single direction without any twisting or turning, relative to the container, towards a position at which the lid covers the opening is sufficient to cause the first part and the second part of the securing means to engage with each other.
- the base may be configured such that the first part and the second part of the securing means engage with one another when, in use, the lid is pressed on to the container.
- the base may be configured such that the first part and the second part of the securing means engage with one another when, in use, the lid is slid into place over the opening.
- the securing means may be configured such that the force required to remove the lid from the container is greater than forces that may typically be exerted on the base during use, e.g. during the playing of a game. For instance, during the playing of a tetherball game, significant lateral forces may be exerted on the base as a ball swings on a cord around a pole attached to the base.
- the securing means may be configured such that such lateral forces would not be sufficient to inadvertently remove the lid from the container during play.
- the securing means may be configured such that the force required for a user to secure the lid in place over the opening may be lower than the force required for a user to remove the lid from the container.
- the securing means may be configured such that the lid may be securable in place over the opening by a user exerting a downward force on the lid towards the container, and the lid may be removable by exerting an upward force on the lid away from the container.
- the upward force required to remove the lid from the container may be greater than the downward force required to secure the lid in place over the opening.
- the securing means may comprise only the first part and the second part, i.e. the securing means may consist of the first part and the second part.
- the securing means may be free from additional parts such as lever clips, latches, ties, clasps or the like, since such additional parts are not required to secure the lid in place over the opening.
- the securing means may be relatively reliable and durable.
- the securing means may also be relatively simple to use, as it may require less manual dexterity on the part of the user to open and close the container.
- the first part of the securing means being fixedly attached to or integrally formed with the container means that the first part of the securing means is not moveable relative to the container.
- the second part of the securing means being fixedly attached to or integrally formed with the lid means that the second part of the securing means is not moveable relative to the lid. Therefore, in embodiments in which the securing means comprises only the first part and the second part, the securing means does not comprise any moving parts, i.e. parts which are required to be directly moved by a user in order to secure the lid to the container. This may reduce manufacturing cost and complexity.

- the lid 2 is first placed on to the container 1 such that the release tabs 22 overlap the projection 11 and the walls 25 rest on the projection 11 as shown in FIG. 5 b . In this position, the release tabs 22 and the projection 11 will inhibit any lateral movement of the lid 2 relative to the container.
- a downward force in the vertical direction as shown in FIGS. 5 a - c is then applied to the lid 2 by a user.
- the projection 11 may comprise a chamfer. As a result of the downward force and the chamfer of the projection 11 , a resulting outward force in the horizontal direction as shown in FIGS.
- the middle portion 221 of the release tab 22 is maintained at a distance from the container 1 by the first and second wing portions 222 a , 222 b .
- This provides a gap between the release tab 22 and the container 1 , enclosed by the first and second wing portions 222 a , 222 b , which enables a user to grip the inward facing surface of the middle portion 221 of the release tab 22 .
- a force is applied by a user on the inward facing surface of the middle portion 221 of the release tab 22 .
- This force causes the first portion 241 of the skirt 24 proximate the release tab 22 to move outwardly relative to the second portion 242 , and with it an end of the ridge 25 proximate the release tab 22 moves downwards and outwards. This allows a portion of the projection 11 to pass the end of the ridge 25 .
- An upward force is then applied to the lid 2 , by pulling up on the release tab 22 . This causes the portion of the projection 11 to pass the end of the ridge 25 . Continued upward pulling on the release tab 22 causes the remainder of the projection 11 to pass the ridge 25 until the lid can be removed from the container 1 .
- FIGS. 6 a and 6 b show schematic close-up cross-sectional side views of a portion of a corner of a lid 2 ′ and a portion of a corner of a container 1 ′ according to an alternative embodiment of the disclosure.

- the lip 110 and the lip-receiving portion 212 extend around the periphery of the container 1 ′ and lid 2 ′, respectively, only in the region of the release tab 22 ′. In an alternative embodiment, the lip 110 and the lip-receiving portion 212 extend continuously around the entire periphery of the container 1 ′ and lid 2 ′ respectively.
- a force is applied by a user on the inward facing surface of the middle portion 221 ′ of the release tab 22 ′ proximate an end 223 of the release tab 22 ′ that is distal from the groove 21 ′.
- This force provides a moment at the groove 21 ′ to overcome the biasing force between the walls 211 a , 211 b .
- This increases the distance between the first and second opposing walls 211 a , 211 b at the neck portion, allowing the lip 110 to pass through the neck portion and enabling the upper edge of the container 1 ′ to be removed from the groove 21 ′.
- the groove 21 ′ and the upper edge of the container 1 ′ are aligned and a downward force is exerted on the lid 2 ′.
- This causes the lip 110 to force the walls 211 a , 221 b of the groove 21 ′ apart to enable the lip 110 to pass through the neck portion and be received within the lip-receiving portion 212 .
- the biasing force between the walls 211 a , 221 b reduces the distance between the walls 211 a , 221 b to retain the lip 110 within the lip-receiving portion 212 .
- the biasing force between the walls 211 a , 221 b is sufficient to resist lateral forces on the lid 2 ′ in use, in the absence of a moment being applied to the groove 21 ′ by means of the release tab 22 ′, so as to ensure the lid 2 ′ remains secured to the container 1 ′.
- the lid 2 , 2 ′ comprises two release tabs 22 , 22 ′ located at diagonally opposed corners of the lid.
- the lid 2 , 2 ′ may comprise four release tabs 22 , 22 ′, each release tab 22 , 22 ′ being located at a different corner of the lid 2 , 2 ′.

Abstract
A base for a play apparatus is disclosed, which includes: a container defining an internal volume and an opening providing access to the internal volume; a removable lid configured to cover the opening; and a securing means operable to secure the lid in place over the opening; where the securing means comprises a first part and a second part, the first part being fixedly attached to or integrally formed with the container and the second part being fixedly attached to or integrally formed with the lid, the first part and the second part being configured to engage directly with each other to secure the lid in place, in use, when the lid is placed over the opening.
Description
- This application is a National Phase entry of International Application No. PCT/GB2021/050131 under § 371 and claims the benefit of GB Patent Application No. 2000844.7, filed Jan. 21, 2020, which is hereby incorporated by reference in its entirety.
- This disclosure relates to a play apparatus, in particular a base for a play apparatus, e.g. for a tetherball game, such as the well-known tether tennis game Swingball®.
- Play apparatuses for tetherball games are popular, as they allow users to play a ball game in a restricted space without the risk of losing the ball. As well as recreational play, these play apparatuses can also be used as a training apparatus to develop a user's hand-eye co-ordination and reflexes. Conveniently, such an apparatus can be used by a single player, for individual practice, or two or more players, optionally in a competitive game.
- There are many different types and sizes of play apparatus for tetherball games available, including, for example, tether tennis apparatus and tether football apparatus.
- GB2354018A discloses an example of a base for a tetherball apparatus. A movable stand for supporting a pole has a ballast-containing base with a detachable lid with a hole to receive the pole. The lid is attached to the base by a two-stage attachment, the first being a tongue and groove formation located around the periphery of the base and lid. The second is in the form of two or more locking devices around that base that prevent separation of the tongue and groove arrangement.
- A first aspect of the present disclosure provides a base for a play apparatus, e.g. for a tetherball game. The base comprises: a container defining an internal volume and an opening providing access to the internal volume; a removable lid configured to cover the opening; and a securing means operable to secure the lid in place over the opening. The securing means comprises a first part and a second part, the first part being fixedly attached to or integrally formed with the container and the second part being fixedly attached to or integrally formed with the lid, the first part and the second part being configured to engage directly with each other to secure the lid in place, in use, when the lid is placed over the opening.
- The action of moving the lid, relative to the container, towards a position at which the lid covers the opening may be sufficient to cause the first part and the second part of the securing means to engage with each other. The base may be configured such that a translation of the lid, i.e. linear movement in a single direction without any twisting or turning, relative to the container, towards a position at which the lid covers the opening is sufficient to cause the first part and the second part of the securing means to engage with each other. The base may be configured such that the first part and the second part of the securing means engage with one another when, in use, the lid is pressed on to the container. The base may be configured such that the first part and the second part of the securing means engage with one another when, in use, the lid is slid into place over the opening.
- The securing means may be configured such that the force required to remove the lid from the container is greater than forces that may typically be exerted on the base during use, e.g. during the playing of a game. For instance, during the playing of a tetherball game, significant lateral forces may be exerted on the base as a ball swings on a cord around a pole attached to the base. The securing means may be configured such that such lateral forces would not be sufficient to inadvertently remove the lid from the container during play.
- The securing means may be configured such that the force required for a user to secure the lid in place over the opening may be lower than the force required for a user to remove the lid from the container.
- In an example implementation, the securing means may be configured such that the lid may be securable in place over the opening by a user exerting a downward force on the lid towards the container, and the lid may be removable by exerting an upward force on the lid away from the container. The upward force required to remove the lid from the container may be greater than the downward force required to secure the lid in place over the opening.
- The securing means may comprise only the first part and the second part, i.e. the securing means may consist of the first part and the second part. Conveniently, the securing means may be free from additional parts such as lever clips, latches, ties, clasps or the like, since such additional parts are not required to secure the lid in place over the opening. Furthermore, as a result of the securing means being free from such additional parts, the securing means may be relatively reliable and durable. The securing means may also be relatively simple to use, as it may require less manual dexterity on the part of the user to open and close the container.
- The first part of the securing means being fixedly attached to or integrally formed with the container means that the first part of the securing means is not moveable relative to the container. The second part of the securing means being fixedly attached to or integrally formed with the lid means that the second part of the securing means is not moveable relative to the lid. Therefore, in embodiments in which the securing means comprises only the first part and the second part, the securing means does not comprise any moving parts, i.e. parts which are required to be directly moved by a user in order to secure the lid to the container. This may reduce manufacturing cost and complexity. Furthermore, the securing means may be relatively reliable and durable. The securing means may also be relatively simple to use, as it may require less manual dexterity on the part of the user to open and close the container.
- The container and lid may each be formed as a monolithic part, with the first and second parts of the securing means being integrally formed with the container and the lid respectively.
- The first part of the securing means may comprise a container portion integrally formed with the container. The second part of the securing means may comprise a lid portion integrally formed with the lid. Advantageously, the securing means may not comprise any parts which are formed separately to, and therefore are not integral to, the lid or the container. This may reduce manufacturing complexity and cost.
- As a consequence of the securing means being free from additional parts such as moving parts, lever clips, latches, ties, clasps or the like, the base may have a more regular overall shape and/or may occupy a neater envelope. Consequently, the base may be more efficient to transport, store and/or stack, e.g. in a container or a warehouse or at a point of sale.
- The first part and the second part may engage directly with each other through a snap fit connection. Providing a snap fit connection between the lid and the container may be a convenient way to secure the lid in place over the opening.
- The first part of the securing means may comprise a projection, e.g. a ridge or a lip, protruding from an outer surface of the container. The projection or a plurality of discrete projections may extend around at least 50% of a perimeter of the container.

- The ledge or groove may support or receive the edge of the lid.
- The first part or container portion of the securing means comprising a ledge enables the lid to be supported by the container in use, while enabling the lid to be readily removable simply by lifting the lid away from the container.
- The first part or container portion of the securing means comprising a groove enables a sliding fit between the lid and the container. This provides a secure fit between the lid and the container which may require minimal force to engage.
- In embodiments in which the first part or container portion of the securing means comprises a ledge or groove, the lid may comprise a handle. This may facilitate removal of the lid from the container.
- Additionally or alternatively, the first part and the second part of the securing means may magnetically engage with each other to secure the lid in place over the opening of the container.
- The base of any of the above described embodiments may comprise a handle to facilitate carrying of the base. The handle may be fixedly attached to or integrally formed with the container. The handle may comprise no additional parts or moving parts. Accordingly, manufacturing cost and complexity may be reduced.
- The handle may be arranged over a recess formed in the container. Accordingly, the handle may not protrude beyond the space envelope of the container. Consequently, the base may be more efficient to transport, store and/or stack, e.g. in a shipping container or a warehouse or at a point of sale.
- The base of any of the above described embodiments may comprise one or more, e.g. a plurality of, feet projecting away from an external lower surface of the container.
- The one or more feet may be fixedly attached to or integrally formed with the external lower surface of the container. The provision of one or more feet projecting away from the external lower surface of the container may help to stabilise the base, in use, in particular when it is located on uneven ground. In addition, the feet may act to suspend the remainder of the external lower surface of the container above the ground, in use. As a consequence, bowing of this surface, e.g. as a result of manufacture or of ballast, such as water or sand, being placed in the container, in use, may have a lesser or even no effect on the stability of the base.
- In an example implementation, four feet may project away from the external lower surface of the container. Each of the four feet may be located in or near a different corner of the container.
- The lid of the base of any of the above described embodiments may comprise one or more upstanding walls extending away from an external upper surface of the lid to define a recess in the top of the lid. The recess may be configured to receive a lower portion of another container, in particular another container according to an embodiment described herein. For instance, the recess may be configured to receive, in use, one or more feet projecting away from the external lower surface of the other container.
- The one or more upstanding walls may comprise a single continuous wall extending around the perimeter of the lid. Alternatively, the one or more upstanding walls may comprise a plurality of walls extending around the perimeter of the lid to define the recess.

- Providing the lid with a recess or recesses to receive a lower portion of another container enables multiple bases to be stacked securely on top of each other during transportation and/or storage, for example when displaying the bases at a point of sale.
- The base of any of the above described embodiments may comprise at least one side foot projecting away from an external side surface of the container. The at least one side foot may be fixedly attached to or integrally formed with the container. This may facilitate storage or display of the base in an upright position, which may be beneficial in locations in which there is limited space to store or display the base horizontally.
- In an example embodiment, there may be two side feet projecting away from the external side surface of the container.
- The base of any of the above described embodiments may comprise an aperture located in an upper external surface of the lid for receiving ballast, such as water or sand, when the lid is secured to the container. This advantageously enables the container to be filled with ballast without having to remove the lid, for example when a pole of a play apparatus, e.g. a play apparatus for a tetherball game, is being supported by the base. The base may further comprise a plug configured to close the aperture to prevent ballast from being expelled from the container in use.
- The plug may comprise a tab and the lid may comprise a recess configured to receive the tab, wherein a length of the tab is less than a length of the recess. This advantageously enables easy removal of the plug from a position in which the plug closes the aperture.
- The base may be configured to be attached to a pole of a play apparatus for a tetherball game in any suitable manner. For instance, the lid may have an aperture therethrough which is located to align with a receiving formation, e.g. a socket, on a lower inner surface of the container. A bottom end of the pole may be received in the receiving formation and the pole may extend through the aperture in the lid.
- The lid may comprise a projection, e.g. an annular projection, which extends away from an upper external surface of the lid and which may extend continuously around the circumference of the aperture of the lid through which the pole extends in use to restrict horizontal movement of the pole in use. Alternatively, the lid may comprise a plurality of discrete projections, e.g. annular projections, extending away from an upper external surface of the lid and extending around the circumference of the aperture of the lid through which the pole extends in use to restrict horizontal movement of the pole in use.
- The projection or projections extending around the aperture of the lid through which the pole extends, in use, help to maintain lateral stability of the pole in use. The projection or projections may also provide a locating feature which helps a user to align the pole with the aperture of the lid for insertion of the pole through the aperture.
- Additionally or alternatively, the projection or projections extending around the aperture of the lid through which the pole extends in use may extend away from an upper internal surface of the lid.
- Alternatively or additionally, the lid may be thicker in a region near, e.g. around, the aperture of the lid through which the pole extends in use.
- The projection or projections and/or thicker region near the aperture of the lid through which the pole extends in use may act to locally increase the strength and/or stiffness of the lid. Consequently, movement of the pole within the aperture, in use, may be less likely to damage, deform or break the lid.
- In embodiments in which the container comprises a plurality of feet projecting away from the external lower surface of the container and the lid comprises the projection or projections extending around the aperture of the lid through which the pole extends in use, the space provided between the plurality of feet can accommodate the projection or projections when multiple bases are stacked on top of one another.

- The action of moving the lid, relative to the container, towards a position at which the lid covers the opening may be sufficient to cause the first part and the second part of the securing means to engage with each other. The base may be configured such that a translation of the lid, i.e. linear movement in a single direction without any twisting or turning, relative to the container, towards a position at which the lid covers the opening is sufficient to cause the first part and the second part of the securing means to engage with each other. The base may be configured such that the first part and the second part of the securing means engage with one another when, in use, the lid is pressed on to the container. The base may be configured such that the first part and the second part of the securing means engage with one another when, in use, the lid is slid into place over the opening.
- The securing means may be configured such that the force required to remove the lid from the container is greater than forces that may typically be exerted on the base during use, e.g. during the playing of a game. For instance, during the playing of a tetherball game, significant lateral forces may be exerted on the base as a ball swings on a cord around a pole attached to the base. The securing means may be configured such that such lateral forces would not be sufficient to inadvertently remove the lid from the container during play.
- The securing means may be configured such that the force required for a user to secure the lid in place over the opening may be lower than the force required for a user to remove the lid from the container.
- In an example implementation, the securing means may be configured such that the lid may be securable in place over the opening by a user exerting a downward force on the lid towards the container, and the lid may be removable by exerting an upward force on the lid away from the container. The upward force required to remove the lid from the container may be greater than the downward force required to secure the lid in place over the opening.
- The securing means may comprise only the first part and the second part, i.e. the securing means may consist of the first part and the second part. Conveniently, the securing means may be free from additional parts such as lever clips, latches, ties, clasps or the like, since such additional parts are not required to secure the lid in place over the opening. Furthermore, as a result of the securing means being free from such additional parts, the securing means may be relatively reliable and durable. The securing means may also be relatively simple to use, as it may require less manual dexterity on the part of the user to open and close the container.
- The first part of the securing means being fixedly attached to or integrally formed with the container means that the first part of the securing means is not moveable relative to the container. The second part of the securing means being fixedly attached to or integrally formed with the lid means that the second part of the securing means is not moveable relative to the lid. Therefore, in embodiments in which the securing means comprises only the first part and the second part, the securing means does not comprise any moving parts, i.e. parts which are required to be directly moved by a user in order to secure the lid to the container. This may reduce manufacturing cost and complexity. Furthermore, the securing means may be relatively reliable and durable. The securing means may also be relatively simple to use, as it may require less manual dexterity on the part of the user to open and close the container.
- The container and lid may each be formed as a monolithic part, with the first and second parts of the securing means being integrally formed with the container and the lid respectively.
- The first part of the securing means may comprise a container portion integrally formed with the container. The second part of the securing means may comprise a lid portion integrally formed with the lid. Advantageously, the securing means may not comprise any parts which are formed separately to, and therefore are not integral to, the lid or the container. This may reduce manufacturing complexity and cost.
- As a consequence of the securing means being free from additional parts such as moving parts, lever clips, latches, ties, clasps or the like, the base may have a more regular overall shape and/or may occupy a neater envelope. Consequently, the base may be more efficient to transport, store and/or stack, e.g. in a container or a warehouse or at a point of sale.
- The first part and the second part may engage directly with each other through a snap fit connection. Providing a snap fit connection between the lid and the container may be a convenient way to secure the lid in place over the opening.
- The first part of the securing means may comprise a projection, e.g. a ridge or a lip, protruding from an outer surface of the container. The projection or a plurality of discrete projections may extend around at least 50% of a perimeter of the container. A single projection or a plurality of discrete projections may extend around the entirety of the container. The second part of the securing means may comprise a groove or grooves configured to receive the projection(s). The groove may be defined at least in part by two side walls. At least one of the side walls may be resiliently biased to provide a snap fit between the container and the lid. The two side walls may oppose each other.
- The projection(s) may be shaped, e.g. chamfered, to facilitate the projection(s) entering the groove(s) to secure the lid in place. The projection(s) may be shaped such that it is harder to remove the projection(s) from the groove(s) when removing the lid from the container.
- Alternatively, the first part of the securing means may comprise a groove within an outer surface of the container. The second part of the securing means may comprise a downward projection protruding from a surface of the lid. The projection or a plurality of discrete projections may be arranged to extend, in use, around at least 50% of the perimeter of the opening. A single projection or a plurality of discrete projections may be arranged to extend, in use, around the entirety of the perimeter of the opening. The groove may be defined at least in part by two side walls. At least one of the side walls may be resiliently biased to provide a snap fit between the container and the lid. The two side walls may oppose each other.
- The lid may comprise at least one release tab projecting in a direction away from a lower surface of the lid for removing the lid from the container. The release tab may enable leverage to be applied, to facilitate removal of the lid from the container. One or more of the release tabs may be arranged such that there is a gap between the release tab(s) and the container when the lid is secured to the container. The gap may allow a user to insert one or more fingers between the release tab and the container to apply a force to the release tab in a direction away from the container, and therefore apply leverage, e.g. to the resiliently biased side wall(s) defining the groove.
- The lid may comprise a plurality of release tabs. The release tabs may be disposed at intervals, e.g. regularly spaced, around a perimeter of the lid. The lid may comprise two, three, four, five or six release tabs.
- The lid may comprise two release tabs to enable additional leverage to be applied to the resiliently biased side wall(s) defining the groove. This may further ease the removal of the lid from the container. The two release tabs may, for example, be located at diametrically opposing points or at diagonally opposing corners of the lid to ease removal of the lid from the container even further. In other embodiments, the lid may comprise more than two release tabs. In some embodiments, a release tab may be provided at each corner of the lid.
- The lid may comprise a ridge at least partially defining the or each of the grooves of the second part of the securing means. The lid may comprise a discrete ridge defining in part each of the grooves of the second part of the securing means. In embodiments also comprising one or more release tabs, the or each discrete ridge may extend along a side of the lid and terminate before reaching a release tab.
- It will be appreciated that the base is not limited to any particular cross-sectional shape. Although the accompanying drawings show embodiments of the base having a rectangular cross-section, alternative embodiments of the base may comprise for example a circular or elliptical cross-section or a cross-section of any suitable polygonal or curvilinear shape. In embodiments in which the base comprises a circular cross-section and the lid comprises more than one release tab, the release tabs may be spaced equidistantly about the circular perimeter of the lid.
- The groove may comprise a projection-receiving portion configured to receive the projection, e.g. lip. The projection may be retainable in the projection-receiving portion to secure the lid in place over the opening of the container. The projection may be releasable from the projection-receiving portion by means of a user applying leverage via the release tab.
- In another embodiment, the second part or lid portion of the securing means may comprise an edge of the lid and the first part or container portion of the securing means comprises a ledge or groove configured to accommodate the edge of the lid. The ledge or groove may support or receive the edge of the lid.
- The first part or container portion of the securing means comprising a ledge enables the lid to be supported by the container in use, while enabling the lid to be readily removable simply by lifting the lid away from the container.
- The first part or container portion of the securing means comprising a groove enables a sliding fit between the lid and the container. This provides a secure fit between the lid and the container which may require minimal force to engage.
- In embodiments in which the first part or container portion of the securing means comprises a ledge or groove, the lid may comprise a handle. This may facilitate removal of the lid from the container.
- Additionally or alternatively, the first part and the second part of the securing means may magnetically engage with each other to secure the lid in place over the opening of the container.
- The base of any of the above described embodiments may comprise a handle to facilitate carrying of the base. The handle may be fixedly attached to or integrally formed with the container. The handle may comprise no additional parts or moving parts. Accordingly, manufacturing cost and complexity may be reduced.
- The handle may be arranged over a recess formed in the container. Accordingly, the handle may not protrude beyond the space envelope of the container. Consequently, the base may be more efficient to transport, store and/or stack, e.g. in a shipping container or a warehouse or at a point of sale.
- Another aspect provides a base for a play apparatus, e.g. for a tetherball game, comprising: a container defining an internal volume and an opening providing access to the internal volume; a removable lid configured to cover the opening; a securing means operable to secure the lid in place over the opening; and one or more recesses in the top of the lid configured to receive a lower portion of another container, in particular another container according to an embodiment described herein.
- The one or more recess may comprise a single recess defined by one or more upstanding walls extending away from an external upper surface of the lid. The one or more upstanding walls may comprise a single continuous wall extending around the perimeter of the lid. Alternatively, the one or more upstanding walls may comprise a plurality of walls extending around the perimeter of the lid to define the recess. In embodiments comprising a plurality of feet projecting away from an external lower surface of the container, the recess may be configured to receive, in use, one or more of the feet. The one or more recess may comprise a plurality of recesses in an external upper surface of the lid, wherein each of the plurality of recesses is configured to receive one of the plurality of feet.
- Providing the lid with a recess or recesses to receive a lower portion of another container enables multiple bases to be stacked securely on top of each other during transportation and/or storage, for example when displaying the bases prior to sale.
- The base may comprise at least one side foot projecting away from an external side surface of the container. The at least one side foot may be fixedly attached to or integrally formed with the container. This may facilitate storage or display of the base in an upright position, which may be beneficial in locations in which there is limited space to store or display the base horizontally.
- In an example embodiment, there may be two side feet projecting away from the external side surface of the container.
- The base may comprise an aperture located in an upper external surface of the lid for receiving ballast, such as water or sand, when the lid is secured to the container. This advantageously enables the container to be filled with ballast without having to remove the lid, for example when a pole of a play apparatus, e.g. a play apparatus for a tetherball game, is being supported by the base. The base may further comprise a plug configured to close the aperture to prevent ballast from being expelled from the container in use.
- The plug may comprise a tab and the lid may comprise a recess configured to receive the tab, wherein a length of the tab is less than a length of the recess. This advantageously enables easy removal of the plug from a position in which the plug closes the aperture.
- The base may be configured to be attached to a pole of a play apparatus for a tetherball game in any suitable manner. For instance, the lid may have an aperture therethrough which is located to align with a receiving formation, e.g. socket, on a lower inner surface of the container. A bottom end of the pole may be received in the receiving formation and the pole may extend through the aperture in the lid.
- The lid may comprise a projection, e.g. an annular projection, which extends away from an upper external surface of the lid and which may extend continuously around the circumference of the aperture of the lid through which the pole extends in use to restrict horizontal movement of the pole in use. Alternatively, the lid may comprise a plurality of discrete projections, e.g. annular projections, extending away from an upper external surface of the lid and extending around the circumference of the aperture of the lid through which the pole extends in use to restrict horizontal movement of the pole in use.
- The projection or projections extending around the aperture of the lid through which the pole extends in use help to maintain lateral stability of the pole in use. The projection or projections also provide a locating feature which helps a user to align the pole with the aperture of the lid for insertion of the pole through the aperture.
- The securing means may comprise a first part and a second part, the first part being fixedly attached to or integrally formed with the container and the second part being fixedly attached to or integrally formed with the lid, the first part and the second part being configured to engage directly with each other to secure the lid in place, in use, when the lid is placed over the opening.

- The provision of one or more feet projecting away from the external lower surface of the container may help to stabilise the base, in use, in particular when it is located on uneven ground. In addition, the feet may act to suspend the remainder of the external lower surface of the container above the ground, in use. As a consequence, bowing of this surface, e.g. as a result of manufacture or of ballast, such as water or sand, being placed in the container, in use, may have a lesser or even no effect on the stability of the base.

The gap may allow a user to insert one or more fingers between the release tab and the container to apply a force to the release tab in a direction away from the container, and therefore apply leverage, e.g. to the resiliently biased side wall(s) defining the groove.
- The lid may comprise a plurality of release tabs. The release tabs may be disposed at intervals, e.g. regularly spaced, around a perimeter of the lid. The lid may comprise two, three, four, five or six release tabs.
- The lid may comprise two release tabs to enable additional leverage to be applied to the resiliently biased side wall(s) defining the groove. This may further ease the removal of the lid from the container. The two release tabs may, for example, be located at diametrically opposing points or at diagonally opposing corners of the lid to ease removal of the lid from the container even further. In other embodiments, the lid may comprise more than two release tabs. In some embodiments, a release tab may be provided at each corner of the lid.
- The lid may comprise a ridge at least partially defining the or each of the grooves of the second part of the securing means. The lid may comprise a discrete ridge defining in part each of the grooves of the second part of the securing means. In embodiments also comprising one or more release tabs, the or each discrete ridge may extend along a side of the lid and terminate before reaching a release tab.
- It will be appreciated that the base is not limited to any particular cross-sectional shape. Although the accompanying drawings show embodiments of the base having a rectangular cross-section, alternative embodiments of the base may comprise for example a circular or elliptical cross-section or a cross-section of any suitable polygonal or curvilinear shape. In embodiments in which the base comprises a circular cross-section and the lid comprises more than one release tab, the release tabs may be spaced equidistantly about the circular perimeter of the lid.
- The groove may comprise a projection-receiving portion configured to receive the projection, e.g. lip. The projection may be retainable in the projection-receiving portion to secure the lid in place over the opening of the container. The projection may be releasable from the projection-receiving portion by means of a user applying leverage via the release tab.
- In another embodiment, the second part or lid portion of the securing means may comprise an edge of the lid and the first part or container portion of the securing means comprises a ledge or groove configured to accommodate the edge of the lid. The ledge or groove may support or receive the edge of the lid.
- The first part or container portion of the securing means comprising a ledge enables the lid to be supported by the container in use, while enabling the lid to be readily removable simply by lifting the lid away from the container.
- The first part or container portion of the securing means comprising a groove enables a sliding fit between the lid and the container. This provides a secure fit between the lid and the container which may require minimal force to engage.
- In embodiments in which the first part or container portion of the securing means comprises a ledge or groove, the lid may comprise a handle. This may facilitate removal of the lid from the container.
- Additionally or alternatively, the first part and the second part of the securing means may magnetically engage with each other to secure the lid in place over the opening of the container.
- The base of any of the above described embodiments may comprise a handle to facilitate carrying of the base. The handle may be fixedly attached to or integrally formed with the container. The handle may comprise no additional parts or moving parts. Accordingly, manufacturing cost and complexity may be reduced.
- The handle may be arranged over a recess formed in the container. Accordingly, the handle may not protrude beyond the space envelope of the container. Consequently, the base may be more efficient to transport, store and/or stack, e.g. in a shipping container or a warehouse or at a point of sale.
- Another aspect provides a base for a play apparatus, e.g. for a tetherball game, comprising: a container defining an internal volume and an opening providing access to the internal volume; a removable lid configured to cover the opening; a securing means operable to secure the lid in place over the opening; and an aperture located in an upper external surface of the lid for receiving ballast, such as water or sand, when the lid is secured to the container.
- This advantageously enables the container to be filled with ballast without having to remove the lid, for example when a pole of a play apparatus, e.g. a play apparatus for a tetherball game, is being supported by the base. The base may further comprise a plug configured to close the aperture to prevent ballast from being expelled from the container in use.
- The plug may comprise a tab and the lid may comprise a recess configured to receive the tab, wherein a length of the tab is less than a length of the recess. This advantageously enables easy removal of the plug from a position in which the plug closes the aperture.
- The base may be configured to be attached to a pole of a play apparatus for a tetherball game in any suitable manner. For instance, the lid may have an aperture therethrough which is located to align with a receiving formation, e.g. socket, on a lower inner surface of the container. A bottom end of the pole may be received in the receiving formation and the pole may extend through the aperture in the lid.
- The lid may comprise a projection, e.g. an annular projection, which extends away from an upper external surface of the lid and which may extend continuously around the circumference of the aperture of the lid through which the pole extends in use to restrict horizontal movement of the pole in use. Alternatively, the lid may comprise a plurality of discrete projections, e.g. annular projections, extending away from an upper external surface of the lid and extending around the circumference of the aperture of the lid through which the pole extends in use to restrict horizontal movement of the pole in use.
- The projection or projections extending around the aperture of the lid through which the pole extends in use help to maintain lateral stability of the pole in use. The projection or projections also provide a locating feature which helps a user to align the pole with the aperture of the lid for insertion of the pole through the aperture.
- The securing means may comprise a first part and a second part, the first part being fixedly attached to or integrally formed with the container and the second part being fixedly attached to or integrally formed with the lid, the first part and the second part being configured to engage directly with each other to secure the lid in place, in use, when the lid is placed over the opening.
- The action of moving the lid, relative to the container, towards a position at which the lid covers the opening may be sufficient to cause the first part and the second part of the securing means to engage with each other. The base may be configured such that a translation of the lid, i.e. linear movement in a single direction without any twisting or turning, relative to the container, towards a position at which the lid covers the opening is sufficient to cause the first part and the second part of the securing means to engage with each other. The base may be configured such that the first part and the second part of the securing means engage with one another when, in use, the lid is pressed on to the container. The base may be configured such that the first part and the second part of the securing means engage with one another when, in use, the lid is slid into place over the opening.
- The securing means may be configured such that the force required to remove the lid from the container is greater than forces that may typically be exerted on the base during use, e.g. during the playing of a game. For instance, during the playing of a tetherball game, significant lateral forces may be exerted on the base as a ball swings on a cord around a pole attached to the base. The securing means may be configured such that such lateral forces would not be sufficient to inadvertently remove the lid from the container during play.
- The securing means may be configured such that the force required for a user to secure the lid in place over the opening may be lower than the force required for a user to remove the lid from the container.
- In an example implementation, the securing means may be configured such that the lid may be securable in place over the opening by a user exerting a downward force on the lid towards the container, and the lid may be removable by exerting an upward force on the lid away from the container. The upward force required to remove the lid from the container may be greater than the downward force required to secure the lid in place over the opening.
- The securing means may comprise only the first part and the second part, i.e. the securing means may consist of the first part and the second part. Conveniently, the securing means may be free from additional parts such as lever clips, latches, ties, clasps or the like, since such additional parts are not required to secure the lid in place over the opening. Furthermore, as a result of the securing means being free from such additional parts, the securing means may be relatively reliable and durable. The securing means may also be relatively simple to use, as it may require less manual dexterity on the part of the user to open and close the container.
- The first part of the securing means being fixedly attached to or integrally formed with the container means that the first part of the securing means is not moveable relative to the container. The second part of the securing means being fixedly attached to or integrally formed with the lid means that the second part of the securing means is not moveable relative to the lid. Therefore, in embodiments in which the securing means comprises only the first part and the second part, the securing means does not comprise any moving parts, i.e. parts which are required to be directly moved by a user in order to secure the lid to the container. This may reduce manufacturing cost and complexity. Furthermore, the securing means may be relatively reliable and durable. The securing means may also be relatively simple to use, as it may require less manual dexterity on the part of the user to open and close the container.
- The container and lid may each be formed as a monolithic part, with the first and second parts of the securing means being integrally formed with the container and the lid respectively.
- The first part of the securing means may comprise a container portion integrally formed with the container. The second part of the securing means may comprise a lid portion integrally formed with the lid. Advantageously, the securing means may not comprise any parts which are formed separately to, and therefore are not integral to, the lid or the container. This may reduce manufacturing complexity and cost.
- As a consequence of the securing means being free from additional parts such as moving parts, lever clips, latches, ties, clasps or the like, the base may have a more regular overall shape and/or may occupy a neater envelope. Consequently, the base may be more efficient to transport, store and/or stack, e.g. in a container or a warehouse or at a point of sale.
- The first part and the second part may engage directly with each other through a snap fit connection. Providing a snap fit connection between the lid and the container may be a convenient way to secure the lid in place over the opening.
- The first part of the securing means may comprise a projection, e.g. a ridge or a lip, protruding from an outer surface of the container. The projection or a plurality of discrete projections may extend around at least 50% of a perimeter of the container. A single projection or a plurality of discrete projections may extend around the entirety of the container. The second part of the securing means may comprise a groove or grooves configured to receive the projection(s). The groove may be defined at least in part by two side walls. At least one of the side walls may be resiliently biased to provide a snap fit between the container and the lid. The two side walls may oppose each other.
- The projection(s) may be shaped, e.g. chamfered, to facilitate the projection(s) entering the groove(s) to secure the lid in place. The projection(s) may be shaped such that it is harder to remove the projection(s) from the groove(s) when removing the lid from the container.
- Alternatively, the first part of the securing means may comprise a groove within an outer surface of the container. The second part of the securing means may comprise a downward projection protruding from a surface of the lid. The projection or a plurality of discrete projections may be arranged to extend, in use, around at least 50% of the perimeter of the opening. A single projection or a plurality of discrete projections may be arranged to extend, in use, around the entirety of the perimeter of the opening. The groove may be defined at least in part by two side walls. At least one of the side walls may be resiliently biased to provide a snap fit between the container and the lid. The two side walls may oppose each other.
- The lid may comprise at least one release tab projecting in a direction away from a lower surface of the lid for removing the lid from the container.

The lid may comprise a discrete ridge defining in part each of the grooves of the second part of the securing means. In embodiments also comprising one or more release tabs, the or each discrete ridge may extend along a side of the lid and terminate before reaching a release tab.

The ledge or groove may support or receive the edge of the lid.
- The first part or container portion of the securing means comprising a ledge enables the lid to be supported by the container in use, while enabling the lid to be readily removable simply by lifting the lid away from the container.

- Additionally or alternatively, the projection or projections extending around the aperture of the lid through which the pole extends in use may extend away from an upper internal surface of the lid.
- Alternatively or additionally, the lid may be thicker in a region near, e.g. around, the aperture of the lid through which the pole extends in use.
- The projection or projections and/or thicker region near the aperture of the lid through which the pole extends in use may act to locally increase the strength and/or stiffness of the lid. Consequently, movement of the pole within the aperture, in use may be less likely to damage, deform or break the lid.
- The securing means may comprise a first part and a second part, the first part being fixedly attached to or integrally formed with the container and the second part being fixedly attached to or integrally formed with the lid, the first part and the second part being configured to engage directly with each other to secure the lid in place, in use, when the lid is placed over the opening.

FIG. 2 shows three of thecontainers 1 in a stacked arrangement. The main body of thecontainer 1 comprises abottom panel 18 and acontinuous side wall 19 upstanding from thebottom panel 18. Thecontainer 1 further comprises aprojection 11 which extends outwardly away from thecontinuous side wall 19 and extends around the circumference of thecontainer 1. Theprojection 11 is located relatively close to a top edge of thecontinuous side wall 19. Thecontainer 1, including thebottom panel 18, thecontinuous side wall 19, and theprojection 11 are all integrally formed as a single part, typically by any suitable plastic moulding technique. - As can be seen in
FIG. 2 , thecontainer 1 defines an internal volume and has an open top. The internal volume may be utilised to store other parts of the play apparatus, such as, in the example case of a tetherball apparatus for a tether tennis game, the pole in a collapsed configuration, the flexible cord and the ball, and a set of bats. Thelid 2 is configured to close the opening of thecontainer 1 such that the other parts of the tetherball game can be stored within thebase 10 when not in use. Thecontainer 1 may also be utilised to receive ballast, such as water, sand, gravel, stones or rocks, in order to secure the base 10 in position when the play apparatus is in use, e.g. when the play apparatus is being used to play a tetherball game. -
FIG. 3 shows three of thelids 2 in a stacked arrangement, in which the underside of thetop-most lid 2 is visible. Thelid 2 is generally rectangular and comprises tworelease tabs 22 located at diagonally opposing corners. Eachrelease tab 22 comprises amiddle portion 221 which is flanked on either side by first andsecond wing portions lid 2 comprises apanel 23 and askirt 24 which extends from the panel. As shown inFIG. 3 , thelid 2 comprises an annular projection 31 extending away from the underside of thepanel 23 and extending around the circumference of theaperture 3. This aids in supporting the pole of the tetherball game in use. It may also locally increase the rigidity and/or strength of the lid, which may make the lid less prone to being damaged during play. -
FIG. 4 shows a close-up of thetop-most lid 2 ofFIG. 3 in the region of one of therelease tabs 22. Theskirt 24 comprises afirst portion 241 and asecond portion 242. Theskirt 24 further comprises a plurality ofstruts 243 which extend between thepanel 23 and thefirst portion 241 of theskirt 24. Thestruts 243 reinforce thefirst portion 241 of theskirt 24 against thepanel 23. Thesecond portion 242 extends from thefirst portion 241. Thesecond portion 242 is thinner than thefirst portion 241. On an inner side of thelid 2 there is a step where thefirst portion 241 joins the second portion 232. Theskirt 24 comprises fourdiscrete ridges 25. Each of theridges 25 extends along one of the four sides of thelid 2, terminating before therelease tabs 22 of thelid 2. Eachridge 25 extends inwardly of thelid 2 from thesecond portion 242 of theskirt 24. On each of the four sides of thelid 2, agroove 21 is defined between eachridge 25 and the step where thefirst portion 241 joins thesecond portion 242. Thelid 2, including thepanel 23, the first andsecond portions skirt 24, thestruts 243, and theridge 25 are all integrally formed as a single part, typically by any suitable plastic moulding technique. -
FIGS. 5 a-c shows schematically a cross-sectional side view of thelid 2 and thecontainer 1. For clarity, only the features on one side of the base 10 have been labelled. Thebase 10 comprises a securing means operable to releasably secure thelid 2 to thecontainer 1. The securing means comprises a container portion comprising theprojection 11, and a lid portion comprising thegroove 21. As shown inFIGS. 5 a-c , thesecond portion 242 of theskirt 24 is thinner than thefirst portion 241 of theskirt 24. As such, thesecond portion 242 is more flexible in the horizontal direction as shown inFIGS. 5 a-c than thefirst portion 241. When a force is applied to therelease tab 22 outwardly of the base 10 in the horizontal direction as shown inFIGS. 5 a-c , this force is transmitted to thefirst portion 242 and in turn to thefirst portion 241. The thickness of thesecond portion 242 relative to thefirst portion 241 and thestruts 243 will provide an opposing force to the force applied to thefirst portion 241. As such, thefirst portion 241 will move outwardly relative to thesecond portion 242. - In order to secure the
lid 2 to thecontainer 1, thelid 2 is first placed on to thecontainer 1 such that therelease tabs 22 overlap theprojection 11 and thewalls 25 rest on theprojection 11 as shown inFIG. 5 b . In this position, therelease tabs 22 and theprojection 11 will inhibit any lateral movement of thelid 2 relative to the container. A downward force in the vertical direction as shown inFIGS. 5 a-c is then applied to thelid 2 by a user. As shown inFIGS. 5 a-c , theprojection 11 may comprise a chamfer. As a result of the downward force and the chamfer of theprojection 11, a resulting outward force in the horizontal direction as shown inFIGS. 5 a-c is exerted on thesecond portion 242. This moves thesecond portion 242 outwards, and with it theridge 25 moves downwards and outwards. Continued application of the downward force on thelid 2 will cause theridge 25 to continue to move downwards and outwards until theprojection 11 is able to pass theridge 25 to become seated in thegroove 21. Theprojection 11 is then retained in thegroove 21 until thelid 2 is required to be removed from thecontainer 1. - When the
lid 2 is on thecontainer 1, themiddle portion 221 of therelease tab 22 is maintained at a distance from thecontainer 1 by the first andsecond wing portions release tab 22 and thecontainer 1, enclosed by the first andsecond wing portions middle portion 221 of therelease tab 22. In order to release thelid 2 from the container, a force is applied by a user on the inward facing surface of themiddle portion 221 of therelease tab 22. This force causes thefirst portion 241 of theskirt 24 proximate therelease tab 22 to move outwardly relative to thesecond portion 242, and with it an end of theridge 25 proximate therelease tab 22 moves downwards and outwards. This allows a portion of theprojection 11 to pass the end of theridge 25. An upward force is then applied to thelid 2, by pulling up on therelease tab 22. This causes the portion of theprojection 11 to pass the end of theridge 25. Continued upward pulling on therelease tab 22 causes the remainder of theprojection 11 to pass theridge 25 until the lid can be removed from thecontainer 1. -
FIGS. 6 a and 6 b show schematic close-up cross-sectional side views of a portion of a corner of alid 2′ and a portion of a corner of acontainer 1′ according to an alternative embodiment of the disclosure. In the embodiment ofFIG. 6 , an upper edge of thecontainer 1′ comprises alip 110 configured to be retained within agroove 21′ to provide a snap fit between thelid 2′ and thecontainer 1′. Thegroove 21′ comprises a neck portion defined by first and second opposingwalls portion 212. The diameter of the lip-receivingportion 212 is greater than the distance between the first and second opposingwalls walls lid 2′. - The
lid 2′ comprises arelease tab 22′ comprising amiddle portion 221′ which is flanked on either side by first andsecond wing portions 222 a′, 222 b′. In the cross-sections ofFIGS. 6 a and 6 b , thefirst wing portion 222 a′ is visible. Thelip 110 and the lip-receivingportion 212 extend around the periphery of thecontainer 1′ andlid 2′, respectively, only in the region of therelease tab 22′. In an alternative embodiment, thelip 110 and the lip-receivingportion 212 extend continuously around the entire periphery of thecontainer 1′ andlid 2′ respectively. - In order to release the
lid 2′ from thecontainer 1′, a force is applied by a user on the inward facing surface of themiddle portion 221′ of therelease tab 22′ proximate anend 223 of therelease tab 22′ that is distal from thegroove 21′. This force provides a moment at thegroove 21′ to overcome the biasing force between thewalls walls lip 110 to pass through the neck portion and enabling the upper edge of thecontainer 1′ to be removed from thegroove 21′. To secure thelid 2′ on thecontainer 1′, thegroove 21′ and the upper edge of thecontainer 1′ are aligned and a downward force is exerted on thelid 2′. This causes thelip 110 to force thewalls 211 a, 221 b of thegroove 21′ apart to enable thelip 110 to pass through the neck portion and be received within the lip-receivingportion 212. Once thelip 110 is fully seated in the lip-receivingportion 212, the biasing force between thewalls 211 a, 221 b reduces the distance between thewalls 211 a, 221 b to retain thelip 110 within the lip-receivingportion 212. The biasing force between thewalls 211 a, 221 b is sufficient to resist lateral forces on thelid 2′ in use, in the absence of a moment being applied to thegroove 21′ by means of therelease tab 22′, so as to ensure thelid 2′ remains secured to thecontainer 1′. - In the embodiments of
FIGS. 5 and 6 , thelid release tabs lid release tabs release tab lid - In another example embodiment (not illustrated), the container portion of the securing means comprises a lip formed at an upper edge of a container. A lid comprises a downwardly-facing groove defined by two opposing walls. The groove and the lip have corresponding cross-sections, with the distance between the two opposing walls being less than the diameter of the lip when the lid is not secured to the container. Unlike the embodiment of
FIGS. 6 a and 6 b , thegroove 21″ does not comprise a separate neck portion and lip-receiving portion. To secure the lid on the container, the groove and the lip are aligned and a downward force is exerted on the lid, causing the lip to force the walls of the groove apart. Once the lip is fully received in the groove, the biasing force between the walls retains the lip within the groove. -
