Problems solved by technology

Additionally, most disposable earplugs exhibit some degree of stickiness at their outer surface
These unique features make it difficult for traditional rotary dispensing mechanisms to accurately and continuously dispense only a single earbud each time the user rotates the turntable
Additionally, the compressible eartip can easily get caught between the various moving parts of the dispensing mechanism, so failure can occur frequently

Embodiment 1

[0084] Embodiment 1: provide such as figure 2 The dispensing mechanism shown, which comprises a plate with a minor diameter (d) of 119.2mm and a major diameter (D) of 119.95mm (radius 60.35mm at the lobe location), and the width of the outer hub (W ) of 120.5mm (60.25mm radius) divider assembly. The five holes of the divider assembly are uniformly positioned at approximately 72° intervals. The plate was made of CELECON M90 polyacetal from Celanese Corporation and the separator assembly was made of POLIMAXX GA300 from IRPC Public Company Limited. The components were tested according to procedure 1: Rotational Resistance Test, and the data shown in Table 1 were obtained.

Abstract

The present disclosure provides a manually operable dispenser for dispensing earplugs. An exemplary dispenser includes a first dispensing mechanism part and a second dispensing mechanism part that interacts with the first dispensing mechanism part during rotation of the handle. The interaction between the first dispensing mechanism part and the second dispensing mechanism affects the rotational resistance (τ) at the handle such that when the user rotates the handle, the rotational resistance (τ) is at maximum rotation Change between resistance (τmax) and minimum rotation resistance (τmin).

Description

technical field [0001] The present invention relates to product dispensers. More specifically, the present disclosure relates to manually operable dispensers that provide tactile feedback to a user. Background technique [0002] Disposable earplugs are often used in a variety of situations. In many situations, such as in an industrial or manufacturing environment, it is desirable to have a large number of disposable earplugs readily available at all times. Typically, disposable earplugs are provided in bulk, such as loosely held earplugs in large open boxes. Users simply reach into the box and remove the earbuds as needed. [0003] Various disposable eartip dispensers have also been devised in the art. Typically, the dispenser loosely stores a bulk supply of disposable earplugs and provides a manually operable mechanism for dispensing or selling individual earplugs. The dispensing mechanism may comprise a wheel with a series of discrete holes such that the earplugs drop...
