Abstract
An angled plastic tip applicator comprises a compression moulded rigid upper part including a hollow annular tip part being truncated by a convex wall being longitudinally varyingly curved at an impermanent radius. A center tube dependent from the convex wall communicates with an opening in the convex wall. A flat top cap threaded on the tip and having a serrated outer surface has a center pin engageable with the center tube for tight sealing of the applicator. The applicator has a pliable lower metal laminated plastic tubular container wall prevents leaching and pollution of the product.
Claims33
An angled tip emollient applicator comprising an upper rigid hollow tip;
- a collapsible annular container having a generally cylindrical wall forming a pliable tube having a sealed bottom end;
- said rigid tip having a base secured to the upper end of the tube and having a vertical wall and an angled wall truncating said vertical wall;
- said angled wall having a curvilinearly convex shape in a longitudinal direction;
- a multi-lead external thread encircling said base;
- discharge opening located in said angled wall;
- and
- said pliable tube communicating with said opening and depending from said base, and weld-connected thereto and forming a relatively rigid transition region adapted for grasping by the user thereby preventing deformation of the tube prior to removal of the cap and preparatory to application of emollient after removal of the cap;
- said tube being expandable to draw excess emollient into the tube attendant to the user releasing pressure thereon.
An elongated angled tip applicator for storing and dispensing semi-liquid substances, and comprising:
- an axially extending annular tip and an angled wall truncating said annular tip having a discharge opening;
- an applicator base merging with one end of said tip;
- said angled wall being convexed at impermanent radius and extending adjacent to said base to provide an extensive application surface at one side of the tip;
- said angled wall having an opening coaxial with an axis of said applicator;
- a tube of slightly larger diameter than said tip dependent from said base and communicating with said opening;
- a multi-lead external thread encompassing said applicator base;
- a hollow cap having an end wall at one end and an internal thread at the other end engaging with said external thread for closing said applicator;
- a pin projecting from said cap and tightly sealing said tube upon insertion thereof into said discharge opening and;
- a shoulder at the applicator base limiting rotational displacement of said cap attendant to closing of said applicator.
An angled tip applicator comprising a hollow upper rigid tip including a base;
- a collapsible annular container having a cylindrical wall with a sealed bottom end;
- said rigid tip comprising a base and a vertical wall extending from the base and an angled wall truncating said vertical wall;
- said angled wall having a curvilinearly convex shape in a longitudinal direction for a major portion of the length of said vertical wall;
- thread means encircling the tip adjacent said base;
- a discharge opening in said angled wall;
- said container defining with said cylindrical wall a rigid section at the base and a pliable tube depending from said base and communicating with said opening;
- means interconnecting the tip and the container and said angled wall extending from adjacent said base to the outer end of the tip.
