Slip-resistant autoinjectors
View Patent ↗In an embodiment, the present invention provides an autoinjector that has one or more slip-resistant features. In certain embodiments, the exterior surface of the autoinjector housing forms at least one of indentures and protrusions that impart a slip-resistant texture to the housing of the autoinjector. In other embodiments, the one or more slip-resistant features are included on a label, which comprises a label substrate and is attached to the exterior surface of the housing of the autoinjector. The features are designed to improve the handling properties of the autoinjector and reduce the likelihood that the autoinjector will slip out of a user's or caregiver's hand during use.
1. An autoinjector comprising:
a housing having an interior surface and an exterior surface and a proximal end and a distal end, and a medicament situated within the housing, wherein a slip-resistant label is attached to the exterior surface of the housing, wherein said slip-resistant label comprises a label substrate containing printing thereon, and wherein said slip-resistant label further comprises one of a coating selected from either a) a varnish coating at least a portion of the label substrate, wherein the varnish forms a pattern on at least a portion of the label substrate or has one or more rubberized or textured properties, or b) a film coating and providing a matte finish imparting a slip-resistant texture to at least a portion of the label substrate.
2. The autoinjector according to claim 1 , wherein the slip-resistant label comprises the varnish coating at least a portion of the label substrate and the varnish forms a pattern on at least a portion of the label substrate.
3. The autoinjector according to claim 2 , wherein the varnish has been cured by ultraviolet light.
4. The autoinjector according to claim 2 , wherein the varnish is a solvent-based varnish or an epoxy-based varnish.
5. The autoinjector according to claim 2 , wherein the varnish comprises a gloss varnish.
6. The autoinjector according to claim 2 , wherein the varnish has one or more rubberized or textured properties.
7. The autoinjector according to claim 1 , wherein the slip-resistant label covers at least about 30% of the exterior surface of the housing.
8. The autoinj ector according to claim 1 , wherein the slip-resistant label comprises the film coating and providing a matte finish imparting a slip-resistant texture to at least a portion of the label substrate.
9. The autoinjector according to claim 1 , wherein the slip-resistant label comprises the varnish coating at least a portion of the label substrate and wherein the varnish has one or more rubberized or textured properties.
10. The autoinjector according to claim 9 , wherein the varnish has been cured by ultraviolet light.
11. The autoinjector according to claim 9 , wherein the varnish is a solvent-based varnish or an epoxy-based varnish.
12. The autoinjector according to claim 9 , wherein the varnish comprises a gloss varnish.
13. The autoinjector according to claim 1 , wherein the label substrate has a slippery surface.
