  • Patent number: 11890444
    Abstract: The invention relates to a connector (1) constituted by: base provided with a tubular wall (13) closed by a bottom wall (11) provided with at least one through-opening (111); a membrane provided with a flexible wall (23) having a central opening, a tubing (22) placed in the opening of the flexible wall; sealing means for preventing a liquid from leaving the connector through the tubing. The base and the membrane are fixed to each other in a liquid-tight manner. The flexible wall allows axial displacement of the tubing so that it can be moved between a closed position, in which a liquid cannot leave the connector through the conduit of the tubing, and an open position, in which a liquid from can leave the connector through the tubing. Retaining means (121, 222a) maintain the tubing (22) closed with a force that can be overcome manually to open it.

  • Patent number: 8882737
    Abstract: A self standing bag having two side wall sheets and a bottom sheet. To flatten the bag, the bottom sheet is sandwiched between the two side wall sheets and symmetrically folded along a line parallel to its bottom edge, separating the bag into a four-layer part and a two-layer part. In the two-layer part, the bag includes first sloped sealing lines extending between a first two points on the top edges of the side wall sheets and spaced from the vertical side wall edges by a first distance, to a second two points spaced from the vertical edges of the side wall sheets by a second distance less than the first distance. The four-layer part includes second sloped sealing lines extending between the second two points and a third two points on the bottom edges of the side wall sheets.

  • Patent number: 8678224
    Abstract: An insert for a receptacle intended to contain a concentrated product in solid or liquid form includes a main part (1) formed by a base (2) extended on the edge by a wall (3) perpendicular to the base, with an opening (4) formed in the base. A receptacle with such an insert is also provided. In order to enable emptying the receptacle entirely without leaving dead spaces in which the products to be solubilized may accumulate, the face of the base (2) intended to be in the receptacle after assembly is concave at the opening, so that the opening is at the bottom of a trough (6). This avoids corners in which the liquid would not circulate sufficiently, and prevents solid product from accumulating elsewhere than in the trough, so that it is always subjected to the flow of liquid.

  • Patent number: 8336812
    Abstract: An engine attachment for an assembly system configured to be mounted between a rigid structure of an attachment strut of an aircraft engine and an engine. The attachment includes a main body, a rudder bar on an articulated mounting on the main body by a hinge pin, and two thrust absorption rods each with one end connected to the rudder bar. The main body includes a first main brace and a second main brace superimposed on the first brace. The hinge pin is formed by a first portion and a second portion, wherein the first portion is made in one piece with the first brace and the second portion is made in one piece with the second brace. Furthermore, the braces define a stop limit surface configured to limit rotation of the rudder bar.

  • Publication number: 20120067898
    Abstract: The invention concerns an insert for a receptacle that is to contain a concentrated product in solid or liquid form, comprising a main part (1) formed by a base (2) extended on the edge by a wall (3) perpendicular to the base, an opening (4) being produced in the base. The invention also concerns a receptacle provided with an insert according to the invention. The objective of the invention is to develop an insert that enables the receptacle to be emptied entirely without leaving dead spaces in which the products to be solubilised may accumulate. This objective is achieved in accordance with the invention because the face of the base (2) intended to be situated in the receptacle after assembly, the so-called internal face, is concave at the opening so that the latter is situated at the bottom of a trough (6). In this way the formation of corners in which the liquid does not circulate, or does not circulate sufficiently, is avoided.

  • Publication number: 20100016825
    Abstract: The invention relates to the field of containers for providing liquid dialysate concentrates for a dialysis treatment of a patient with the aid of an artificial kidney. Up to now such concentrates have been delivered mainly in rigid plastic containers as the weight of the concentrate requires a certain stability of the container. Such containers also simplify the shipping of large loads as they can easily be arranged in layers on top of each other. These rigid containers have the disadvantage that because of their rigidity they are comparatively expensive as the container walls have to be thick enough leading to higher material expenses. Furthermore, the empty containers are bulky making the further processing cumbersome. The large amount of material to be recycled or discarded adds further to the cost. The invention avoids these drawbacks by proposing a container filled with a liquid dialysate concentrate that is a self-standing bag (1) made of flexible elastomeric sheets.
