Abstract
A tray intended to hold injection device tubes includes a collar at each end of a body. In order to carry out operations of preparing the injection device tubes, the tray includes bores and each bore is configured to receive a body of an injection device tube. Also, each bore of the tray includes a holding portion for holding the upper collar of the tube and the holding portion extends laterally from an introduction portion enabling the passage of the lower collar.
Core Innovation
A tray for holding injection device tubes is described, in which the injection device tubes include a collar at each end of a body. The tray includes bores that receive the body of the tube, where each bore includes a holding portion configured to hold an upper collar and an introduction portion configured to enable passage of a lower collar. The holding portion extends laterally from the introduction portion within a same plane of the tray.
The holding portion includes a vertical wall having a height substantially equal to a diameter of the body of the tube. Elastic elements are disposed between the holding portion and the introduction portion, and the elastic elements form tabs, each tab including a boss separating the holding portion from the introduction portion. The height of the vertical wall is at least a minimum distance between the bosses separating the holding portion from the introduction portion.
The tray is described as stiffened with ribs and can be injection molded from liquid crystal polymer (LCP) for resistance to dry-heat sterilization. The described support and processing workflow includes silicone coating and dry-heat endotoxin reduction, followed by bagging with high-density polyethylene (HDPE) materials and Tyvek, and conditioning per NF ISO 11040-7.
Claims Coverage
The independent claim specifies a tray architecture for injection device tubes with collars at both ends, with separated holding and introduction portions within a same plane and elastic tabs and bosses to enable collar retention and passage. It further constrains the vertical wall height relative to a diameter and relative to a minimum distance between bosses, with dependent refinements to geometry and materials.
Holding and introduction portions for collar retention and passage in a tray bore
A tray for holding injection device tubes including a collar at each end of a body, wherein bores receive the body of the tube; each bore includes a holding portion configured to hold an upper collar and an introduction portion configured to enable passage of a lower collar; the holding portion extends laterally from the introduction portion within a same plane of the tray.
Vertical wall height and elastic tab bosses separating portions
The holding portion includes a vertical wall having a height substantially equal to a diameter of the body of the tube; the tray further comprises elastic elements disposed between the holding portion and the introduction portion, wherein the elastic elements form tabs, each tab including a boss separating the holding portion from the introduction portion; and the height of the vertical wall is at least a minimum distance between the bosses separating the holding portion from the introduction portion.
Dependent refinements to bore contour, material, and portion connectivity (as stated)
Additional limitations are described in dependent claims, including a circular-arc-shaped contour for a front-side holding portion configured to adjustably receive the tube body; plastic material of liquid crystal polymers formed by injection molding; the introduction portion being directly connected to the holding portion; the introduction portion and holding portion together forming a closed shape; and the vertical wall height being substantially equal to a diameter of the holding portion.
The claims cover a stiffened tray with bores whose holding portion holds an upper collar and whose introduction portion enables passage of a lower collar, with both portions laterally extending in a same plane. Separation between holding and introduction portions is achieved using elastic elements forming tabs with bosses, while the vertical wall height is constrained by the tube body diameter and by a minimum distance between the bosses, with further stated dependent refinements to contour, injection-molded LCP material, connection or closed-shape geometry, and proportional wall-height relationships.
Stated Advantages
Resistance to dry-heat sterilization.
