Abstract
Abstract A container-dispenser for cosmetics in solid stick form such as lip salves, the container being of the kind comprising a tubular body, an internally threaded follower slideably and nonrotatably fitted within the body, and a knob actuated screw-threaded spindle engaging the follower to effect sliding of the follower. The follower is formed as a double ended cup for assembly with the spindle either way round, the assembly being inserted into the container body so that a shoulder on the knob snaps past a retaining rib on the body. The follower is provided with a continuous ring of grooves on its periphery at least one of which tends to be aligned with a longitudinal rib in the body on assembly and a thin annular flange, pierced on assembly by the rib on the body, acts as a sliding seal between the follower and the body.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
110 words
In a container-dispenser comprising a tubular body having an inner wall, an internal longitudinal rib formed on the inner wall, an actuating knob rotatably mounted at one end of the body, a screw-threaded spindle extending from the actuating knob to within the body, and a follower slideably and nonrotatably fitted within the body, the screw-threaded spindle engaging with the follower to effect longitudinal sliding of the follower within the body, the improvement comprising the outer wall of the follower defines a continuous ring of alternate adjacent ribs and grooves, one of the grooves engaging with the longitudinal rib on the body to prevent rotation of the follower within the body.
Claim 2
Dependent Claim
110 words
In a container-dispenser comprising a tubular body having an inner wall, an internal longitudinal rib formed on the inner wall, an actuating knob rotatably mounted at one end of the body, a screw-threaded spindle extending from the actuating knob to within the body, and a follower slideably and nonrotatably fitted within the body, the screw-threaded spindle engaging with the follower to effect longitudinal sliding of the follower within the body, the improvement comprising the outer wall of the follower defines a continuous ring of alternate adjacent ribs and grooves, one of the grooves engaging with the longitudinal rib on the body to prevent rotation of the follower within the body.
Claim 3
Dependent Claim
48 words
A container-dispenser according to claim 1 including a thin external integral annular flange on the follower which acts as a sliding seal with the inner wall of the body and is thin enough to be pierced by the longitudinal rib when the follower is assembled with the body.
Claim 4
Dependent Claim
29 words
A container-dispenser according to claim 2 in which the follower is open at both ends, an inner transverse central partition dividing the follower to form a double ended cup.
Claim 5
Dependent Claim
139 words
In a container-dispenser comprising a tubular body, said body having an internal surface formed with an internal inwardly projecting longitudinal rib, a follower fitted within the body and slideable in the longitudinal direction, the outer wall of the follower defining a groove engaging with the longitudinal rib to prevent rotation of the follower within the body, an internal screw thread formed centrally in the follower, an externally threaded spindle engaging with the internal thread of the follower, and a rotatable knob at one end of the spindle for rotating the spindle to effect said longitudinal sliding of the follower, the improvement comprising the longitudinal rib is of Vee-shape cross section having sidewalls which are inwardly inclined to meet at the innermost edge of the rib, the outer wall of the follower defining a continuous ring of adjacent complementary grooves.
Claim 6
Dependent Claim
139 words
In a container-dispenser comprising a tubular body, said body having an internal surface formed with an internal inwardly projecting longitudinal rib, a follower fitted within the body and slideable in the longitudinal direction, the outer wall of the follower defining a groove engaging with the longitudinal rib to prevent rotation of the follower within the body, an internal screw thread formed centrally in the follower, an externally threaded spindle engaging with the internal thread of the follower, and a rotatable knob at one end of the spindle for rotating the spindle to effect said longitudinal sliding of the follower, the improvement comprising the longitudinal rib is of Vee-shape cross section having sidewalls which are inwardly inclined to meet at the innermost edge of the rib, the outer wall of the follower defining a continuous ring of adjacent complementary grooves.
Claim 7
Dependent Claim
86 words
A container-dispenser according to claim 4 in which one end of the body is formed with an internal annular retaining rib and the rotatable knob is formed with an external annular shoulder, the diameter of the internal annular rib being greater than the diameter Of the follower so that the follower and spindle can be inserted through that end of the body and the annular shoulder of the rotatable knob snapped past the internal rib so that the knob closes that end of the tubular body.
