Definitions

  • the refrigeration unit 1 includes an outer case 2 which creates an internal compartment 3.
  • the internal compartment 3 is adapted to support and contain products in a cooled environment, substantially colder than the current exterior or ambient environment of the refrigeration unit 1.
  • the outer case 2 is generally defined by side walls 4, 5, front wall 6 and back wall 7 (obscured in Figure 1). The outer case 2 will be described with reference to Figures 2 and 3.
  • the refrigeration unit 1 has an upper portion 8 and a lower portion 9.
  • the upper portion 8 provides access to the internal compartment 3. As can be seen from
  • the upper portion 8 of the present invention is open and has the advantage of not requiring a lid or door to separate the environment of the internal compartment 3 from the external or ambient environment. This enables consumers to easily see and access the products stored within the internal compartment 3 without needing to open a lid or door, and replacing the lid or door after selecting the desired product from the internal compartment 3.
  • the upper portion 8 of the refrigeration unit 1 includes a skirt 10 which borders and encircles the internal compartment 3 formed by outer case 2.
  • the skirt 10 is provided with a profiled surface (best seen in Figures 2 and 4) adapted to direct chilled air within the internal compartment 3 towards products stored within the internal compartment 3. In this way, the upper portion 8 of refrigeration unit 1 can remain open while maintaining a chilled environment in the internal compartment 3 without the requirement for a lid or door isolating the internal compartment 3.
  • a chilled air curtain is created at the surface of internal compartment 3 isolating the environment created from the external environment.
  • the chilled air directing surface of the skirt 10 can be profiled in a number of ways to achieve the required effect. For example, it can be planar (angled generally upwardly, downwardly or horizontally, the latter two being preferred), or arcuate so that cold air impacting the underside of the skirt is actively “folded” inwardly and downwardly.
  • the skirt 10 shown in Figure 1 is formed from a translucent plastics material. However, this is not essential.
  • the skirt 10 may be provided as a coloured surface or be formed of other firm materials such as aluminium, steel or the like.
  • the advantage of having a translucent plastic skirt includes ease of manufacture. Further advantages include the benefit obtained by consumers standing at an angle to the refrigeration unit 1 who may immediately see the products contained within the refrigeration unit 1 through the transparent skirt 10. Also, a transparent skirt may add to the overall look of the refrigerated unit 1 to create an attractive appearance.
  • the skirt 10 is designed to optimise viewing of all products sitting inside the chiller unit, allow access to the products accommodated within the refrigeration unit 1 , and to optimise the air curtain over the products inside the refrigeration unit 1. It will be understood that the skirt could be formed integrally with walls 4, 5, 6. However, this is a less desirable option in terms of ease of production of the refrigeration unit 1 and could interfere with consumer awareness of the products held in the refrigeration unit 1 .
  • the refrigeration unit 1 also includes a promotional display portion 1 1 . This can be used to advertise the products contained within the refrigeration unit 1 , price and other marketing or consumer information which may be appropriate. It will, however, be appreciated that the display portion 1 1 is not an essential requirement of the invention or the overall working of the invention.
  • the internal compartment 3 includes dividers 12 which separate the products within the internal compartment 3. The dividers 12 may include price details of the products. Such options are also not essential but are preferred.
