Definitions

  • Disposable plastics ingredient cups are well known and widely used.
  • the ingredients to make one cup of beverage are placed in the base of each plastics cup and then filled cups are nested together to form a stack.
  • the top cup in each stack usually includes a lid or other retainer for its ingredients.
  • the cups usually include stacking features such as a radially inwards projection towards the base of each cup which acts as a stop to support the base of a cup nested inside it and to define a chamber which receives and holds the beverage ingredients.
  • the stacking features are arranged to form a substantially airtight seal. This helps keep the ingredients in the chamber "fresh" and attempts to hold the ingredients in the ingredient chamber.
  • the beverage ingredients are often formed by powdered freeze dried beverages and invariably have a hygroscopic nature.
  • the complete stack of ingredient cups is surrounded by an outer sealed water impermeable wrapping and thus, the seal between adjacent cups only has to provide a secondary seal to keep the ingredients fresh once the stack of cups has been unwrapped. It is desirable that the stacking features formed between adjacent cups have some flexibility so that the nested stack of cups can absorb shock loads applied to it during transport.
  • EP-A-0,228,867 describes such an arrangement in detail where means are provided in the stacking features which flex to allow the stack to absorb shock loads applied to it.
  • the cups do not look as clean and appealing as they should.
  • Another problem with conventional ingredient cups is the size of the ingredient chambers that have to be provided between each pair of nested cups. The volume of this chamber must be sufficient to accommodate the maximum quantity of ingredient that is provided. However it is the volume of the ingredient chambers that determines the spacing between adjacent cups in the stack and hence the maximum number of cups that can be accommodated in each stack of given height. In general the greater the number of cups that can be accommodated in a stack of given height the better.
  • anti-telescoping features in the sidewalls of plastics cups to prevent the stack telescoping to such an extent that nested cups jam into one another so that they cannot easily be denested in use.
  • a disposable plastics ingredient cup includes ingredients in pelleted or tableted form.
  • ingredients in pelleted or tableted form are substantially dust free and, as a result, substantially no contamination of the sidewalls of the cups takes place in spite of a stack of such cups concertinaring to absorb shock loads in use.
  • Another advantage of providing ingredients in this form is that they take up less space than conventional powdered ingredients so that the ingredient chamber formed between adjacent nested cups can be made with a smaller volume. This results in stacks of cups having a shorter height or, being able to nest more cups into each stack of the same height.
  • the plastic cups include sealing and resilient features as described in EP-A-0,228,867 so that the individual ingredient chambers formed between adjacent nested cups are substantially sealed but so that the cups can telescope to some extent to accommodate transport and shock loads applied to them.
  • the ingredients in pelleted and tableted form have an appreciable mechanical strength and, as a result of this, it is possible to dispense with the provision of anti-telescoping features in the sidewall of the cups since, after the stack of cups has telescoped to a sufficient extent to accommodate shock or transient loadings applied to the stack the base of an inner cup engages the ingredients in pelleted or tableted form effectively to prevent further telescoping of the cups in the stack and hence prevent the cups from jamming together.
  • the ingredients may have the form of a flat pellet, tablet or wafer that is circular and substantially the same size the base of each cup.
  • the ingredients may be formed into a single pellet, tablet or wafer which substantially fills the base of each cup. This arrangement ensures the smallest possible volume of ingredient chamber between adjacent cups. It is also possible to provide the ingredients by a number of thinner pellets or wafers each of substantially the same size as the base of the cup. By dividing a single pellet into two or three separate wafers this firstly increases its surface area to volume ratio to improve its solution or dispersion when water is added to produce a reconstituted drink. Also it enables the quantity of ingredient to be controlled easily by adding two or three wafers to make the reconstituted drink weaker or stronger.
  • pellets or tablets of smaller diameter Such pellets or tablets also have a greater surface area to volume ratio and so are easier to dissolve or dispense in water.
  • Hot water may be added to the ingredients to provide hot drinks such as coffee, tea and chocolate or, alternatively, cold water may be added to the ingredients to provide reconstituted fruit juices or fruit squashes.
  • the pelleted or tableted ingredients may include effervescent material to provide a carbonated drink.
  • the ingredient may also be arranged not to provide a beverage but, instead, a medication or a prophylatic liquid such as a mouthwash. Such ingre-dient cups are particularly useful in situations such as a dentist's surgery.
  • Figure 2 is a cross-section through part of a stack of a second example; and, Figure 3 is a cross-section through part of a stack of a third example.
  • Plastics cups 1 having a sidewall 2 and a base 3 are nested together to form a stack 4.
  • the sidewall 2 of each of the cups 1 includes an annular radially inwardly projecting shoulder 5 which supports the base 3 of the next cup 1 nested inside it.
  • the exact form of this projecting shoulder 5 is as described in EP-A-0,228,867 and includes means to allow the stack 4 to absorb shock loads applied to it.
  • Ingredients in the form of a single flat disk like tablet 6 are loaded into the lower portion of each cup 1 and substantially fill ingredient holding chambers 7 formed between the bases 3 of adjacent nested cups 1.
  • the second example is generally similar to the first but in this case the ingredients are formed into smaller diameter tablets 8 and a number of these tablets 8 are loaded into the base of each cup 1.
  • the diameter of the tablets 8 is less than that of the radius of the base 3 of the cup 1.
  • the individual tablets 8 form only a single layer on the base of each cup 1 and again substantially fill the volume of the ingredient storage chamber 7 formed between adjacent nested cups 1.
  • the third example is again generally similar to the first but in this case the ingredients are formed into a number of separate thinner wafers 9 of similar diameter to the disk like tablets 6.

Abstract

L'invention concerne des gobelets en plastique jetables pour ingrédients (1); les ingrédients de préparation de la boisson sont placés dans le fond (3) de chaque gobelet en plastique (1) puis les gobelets remplis (1) sont ensuite emboîtés les uns dans les autres pour former une pile (4). Les gobelets (1) comportent généralement des caractéristiques d'empilage (5) pour soutenir le fond (3) d'un gobelet (1) emboîté dans celui-ci et pour définir une chambre (7) qui reçoit et maintient les ingrédients de boisson. Selon cette invention, un gobelet en plastique jetable (1) contient des ingrédients sous forme de comprimés ou de pastilles (6, 8, 9). En donnant cette forme aux ingrédients, ils ne produisent pratiquement pas de poussière et, par conséquent, les parois latérales des gobelets (1) ne subissent pratiquement aucune contamination; lesdits ingrédients prennent moins de place que les ingrédients en poudre ordinaires si bien que la chambre (7) d'ingrédients formée entre les gobelets emboîtés adjacents (1) peut avoir un volume plus petit.
