AI Technical Summary

Benefits of technology

The present invention provides an autoinjector with slip-resistant features. The housing of the autoinjector may have indentures or protrusions that make it difficult for the label to slide off. The label may also have slip-resistant features such as indentures or protrusions, or it may be coated with a matte finish film. These features help prevent the label from slipping during use, training, or storage. The slip-resistant features can be used in any autoinjector device, including training devices.

Problems solved by technology

Such labels, however, often have a slippery surface, which may decrease the handling properties of the autoinjector and increase the potential for the autoinjector to slip out of a user's or caregiver's hand.

example 1

[0039]This example exemplifies the applying of varnish to a label substrate.

[0040]Three different varnishes were obtained: EOP-18, 135 LP, and Varnish 329. Varnish EOP-18 has a viscosity of about 200 cps, Varnish 329 has a viscosity of about 1,500 cps and is thicker than EOP-18, and Varnish 135 LP has a viscosity of about 120 cps and is tackier than EOP-18 so as to give a “rubbery” or textured feel.

[0041]Each varnish was then applied to label substrates using seven different plates. One plate was smooth and others had a “v” (chevron) pattern or a bumped pattern. With each pattern, the texture was increased by 50% or decreased by 50% so that each varnish was applied in a smooth pattern, a standard bumped pattern, a standard “v” pattern, a 50% reduced bump pattern, a 50% reduced “v” pattern, a 150% bump pattern, and a 150% “v” shaped pattern.

Abstract

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.

Description

BACKGROUND[0001]Technical Field[0002]The present invention relates to an autoinjector that has one or more slip-resistant features. 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.[0003]Background Art[0004]Autoinjectors have become quite popular and have experienced widespread use due to a variety of advantages autoinjectors have over typical manual syringe injectors. A number of autoinjectors are currently commercially available, including EpiPen® (King Pharmaceuticals Inc.), Anapen® (Lincoln Medical Ltd.), Rebiject® II (EMD Serono and Pfizer Inc.), and SureClick™ (Amgen). Generally speaking, an autoinjector is an automatic injection system that is designed to deliver a specific dosage of a medicament into an individual.[0005]Among other things, autoinjectors generally comprise a housing having an exterior surface and an interior surface and a pr...
