Abstract: A system and method for navigating relationships between beans using filters and container managed relationships are provided. With the system and method, filters are specified in the relationship definition of a deployment descriptor of a bean. The filters generate additional predicates to the WHERE clauses in SQL SELECT statements generated based on the contents of the deployment descriptor. Moreover, these filters may be defined such that method parameters may be passed into the resulting deployed code to thereby make them more flexible. Therefore, with the system and method, rather than defining filters programmatically in methods of a bean's implementation class, filters are defined declaratively in the deployment descriptor of the bean. Since these filters are specified in the deployment descriptor of the bean, they are accessible to clients of the bean through the local interface.

Abstract: A sheet material dispenser comprising a container and a stack of folded sheet material, the container surrounding the sheet material and having an aperture through which the sheet material may be drawn in use of the dispenser, wherein the sheet material is folded within the container in a concertina manner.

Abstract: A stack of pre-formed bags, each bag of the stack comprising: a body portion formed by front and rear walls having closed sides, a closed bottom and an open mouth; spaced apart handles extending from the body portion; and front and rear tabs extending from the front and rear walls respectively, the tabs being located between the handles, wherein the front and rear tabs are separably attached to the handles at attachment points spaced from the mouth of the bag the arrangement being such that a bag can be removed from the stack without leaving any waste material behind.

Abstract: A stack (2) of individual, pre-formed bags, each bag (4) comprising: a body portion (6) formed by front (8) and rear (10) walls having closed sides (12), a closed bottom (13) and an open mouth (14); first and second side handles (16, 18) extending away from the body portion (6) at opposite sides of the open mouth (14); and a block header (20) separably connected to the first and second side handles (16, 18), wherein the block header (20) is provided with at least one internal line of weakness (26, 28) such that it may be divided into individual attachment tabs (40, 41, 42), each attachment tab being provided with a support member receiving aperture (43, 44, 45) for receiving a support member of a bag dispenser.

Abstract: A dispenser for dispensing individual pre-formed bags from a stack of such bags, the dispenser comprising a base, a body part, a stack support member attached to the body part and stack retention means attached to the stack support member. In one embodiment, the stack support member may comprise a planar region inclined upwards from back to front with respect to the base, wherein the arrangement is such that, in use, the stack of bags are engaged by the stack retention means in such a manner that the handles of the bags are supported by the planar region of the stack support means and a portion of the bags in the region of the mouth of the bags is disposed on a front edge of the stack support member with the body of the bags depending therefrom, such that a first bag of the stack may conveniently be grasped by a user to remove a single bag in a partially open condition from the stack.
