This specification relates to machines that are adapted to prepare consumable products from capsules and in particular to housings adapted for receiving capsules for such machines.
The following background discussion is not an admission that anything discussed below is citable as prior art or common general knowledge. The documents listed below are incorporated herein in their entirety by this reference to them.
Machines for preparing products, such as beverages like coffee or tea, from single use capsules are becoming increasingly popular. Such machines typically include a brew chamber having a capsule housing that is adapted for receiving a specific capsule. The capsule is supported within the capsule housing while a fluid such as hot water is injected into the capsule to mix with ingredients contained within the capsule. A resulting prepared product is subsequently dispensed from the capsule into a desired receptacle such as a cup or bowl.
A problem with such machines is that the capsule housing is only adapted to receive one specific size or shape of capsule. This limits the options available to consumers to prepare a desired product. Accommodating multiple capsule sizes or shapes is a challenge since the capsule housing requires sufficiently close tolerances to support the capsule during injection of fluid and extraction of the prepared product.
Another problem with such machines is that the capsule housing is not adapted to receive larger volume capsules. This limits the options available to consumers to prepare products having a larger volume of required ingredients (such as products with noodles or other insoluble consumable ingredients).
It is desirable to provide a capsule housing that is adapted to receive larger volume capsules and preferably multiple capsule sizes or shapes while maintaining the close tolerances required to adequately support each capsule.
In one aspect the invention provides a capsule housing for a machine that prepares a product from a capsule, the capsule housing comprising:
In another aspect, the invention provides a capsule housing for a machine that prepares a product from a capsule, the capsule housing comprising:
Other aspects and features of the teachings disclosed herein will become apparent, to those ordinarily skilled in the art, upon review of the following description of the specific examples of the specification.
The drawings included herewith are for illustrating various examples of articles, methods, and apparatuses of the present specification and are not intended to limit the scope of what is taught in any way. For simplicity and clarity of illustration, where considered appropriate, reference numerals may be repeated among the drawings to indicate corresponding or analogous elements.
Various apparatuses or methods will be described below to provide examples of the claimed invention. The claimed invention is not limited to apparatuses or methods having all of the features of any one apparatus or method described below or to features common to multiple or all of the apparatuses described below. The claimed invention may reside in a combination or sub-combination of the apparatus elements or method steps described below. It is possible that an apparatus or method described below is not an example of the claimed invention. The applicant(s), inventor(s) and/or owner(s) reserve all rights in any invention disclosed in an apparatus or method described below that is not claimed in this document and do not abandon, disclaim or dedicate to the public any such invention by its disclosure in this document.
A capsule housing in accordance with the present invention is shown generally at 10 in the Figures.
Capsule housing 10 is adapted to receive a capsule 12 for preparing a desired product in a machine 14 (as shown schematically in
Capsule housing 10 includes an attachment structure 20 for attaching capsule housing 10 to support structure 18. Attachment structure 20 may include a collar 20a with one or more spring biased tabs 20b that are adapted to be removably disposed within corresponding slots 18a defined in support structure 18 (see
A dispensing system 22 may be disposed in capsule housing 10 for dispensing product from capsule 12. Dispensing system 22 may comprise a hollow probe 22a that is adapted to pierce capsule 12.
Capsule housing 10 comprises a hollow body having a capsule containment portion 24, a product collection portion 26 and a product dispensing portion 28.
Capsule containment portion 24 has a side wall 30 that defines a cavity 32 for receiving capsule 12. Capsule containment portion 24 may further include a seat 34 for supporting a first portion of capsule 12 within interior space 20 and a base 36 for supporting a second portion of capsule 10 within capsule containment portion 24.
Product collection portion 26 has a side wall 38 that defines a chamber 40 for collecting product that is prepared from capsule 12. Side wall 38 tapers inwardly from capsule containment portion 24 to direct product to product dispensing portion 28. Chamber 40 has a sufficient volume to allow product to flow from capsule 12 through product dispensing portion 28 without backup or over flow of product.
Product dispensing portion 28 defines an aperture 42 for dispensing product into a desired receptacle 44 such as a cup or bowl. Product dispensing portion 28 may include a sidewall 46 defining a cylindrical passage.

Adjustment system 50 may also be provided to accommodate capsules 12 of different heights. Referring to
An adjustable base 68 is disposed within inner sleeve 64. Adjustable base 68 includes at least one runner 70 adapted for moving along both outer track 62 and inner track 66. In the embodiment depicted in
A collar 72 is disposed over outer sleeve 60 to define seat 34 for supporting capsule 12. A slot 74 is defined in collar 72 for receiving a tab 76 extending from inner sleeve 64. Movement of tab 76 from one end of slot 74 to the other end of slot 74 causes inner sleeve 64 to rotate relative to outer sleeve 60. Because runner 70 is disposed in outer track 62, adjustable base 68 is prevented from rotating with inner sleeve 66. Rotation of inner sleeve 66 thus causes runner 70 to move along inner track 66 to move adjustable base 68 between first height H1 and second height H2. Inner track 66 further includes a ledge 78 at each end of track for supporting adjustable base 68 at first height H1 or second height H2 depending on positioning of tab 76.
Adjustable base 68 includes a dispensing system 22 such as hollow probe 22a. An aperture 80 is defined in adjustable base 68 to accommodate capsules 12 having an integral dispensing nozzle (not shown) rather than requiring dispensing probe 22a.
