Definitions
- the present invention relates to packages of infusible substances such as tea and coffee and more particularly to a package which facilitates infusion and has advantages in use.
- a popular method of preparing tea and coffee is through the use of soft porous bags containing either tea leaves or ground coffee.
- the soft porous bags may be placed in a cup, mug or other container of heated or boiling water to produce the requisite beverage.
- tea bags it is also usual to place one or more bags in a tea pot so as to provide for a multiplicity of beverages.
- the bag Once the bag has been immersed in the water for a sufficient time, it is usually removed prior to the beverage being consumed. This t pically occurs in the case of cups or mugs of beverage although not usually in the case of tea pots.
- the present invention consists in a package of an infusible substance comprising an elongate structure of a liquid permeable material containing an infusible substance, the structure having a lower portion and an upper portion and being sealed at a lower end and an upper end in a manner such that when the lower portion is immersed in a liquid, the infusible substance is retained substantially within the structure whilst the liquid permeates- the infusible substance and the upper portion projects out of the liquid to facilitate gripping thereof.
- the present invention is applicable to a variety of infusible substances.
- infusible substances In particular tea leaves, herbs and coffee.
- These substances will be used for producing beverages such as tea, herbal tea, coffee and the like.
- the amount of substance may be varied quite widely.
- an amount of about 5-7 g is commonly used
- the permeable material is a paper specifically adapted for the purpose of use in packages of infusible material.
- a variety of such papers are well known in the art and the present invention has no particular requirement as to the type of paper chosen.
- the length of the elongate structure maybe similarly varied.
- the package of the invention could be produced in one form with a length that accommodates drinking vessels, such as cups and mugs and in a second form with a length that accommodates tea pots.
- the structure may be dimensioned such that swelling of the substance when it is immersed in the liquid results in the formation of a rod like structure. This will occur as the swelling of the substance tends to fill the structure, In this way, the package will take a relatively stiffer form.
- this stiffening is desirable, it is by no means essential as the inherent nature of the structure facilitates its use a means for stirring the beverage.
- the immersed surface area thereof in use provides for an efficient exchange between the liquid and the infusible substance. This results in the more rapid preparation of the infusion. Moreover, the rate of infusion is enhanced by virtue of the fact that the package serves as a means for readily stirring the infusion.
- the package in cross section may be varied from substantially circular through to a relatively flat ellipse.
- the amount of liquid permeable material used to form the structure will also vary dependant on the cross sectional shape and the overall length.
- a relatively larger amount of permeable material would be used and the structure would tend to assume a relatively flat ellipse in cross section.
- less of the permeable material would be used and the cross sectional configuration would be closer to circular.
- the elongate structure is formed as a tube.
- the lower end is then sealed and the requisite amount of infusible substance filled into the structure.
- an upper end of the structure is then sealed.
- the filling process it is desirable for the filling process to be automated and that various machines are available for this purpose.
- the Italian company IMA SpA manufactures tea bag making machines.
- heat sealing is one means by which the structure may be sealed, other means may be used such as adhesives and crimping.
- An upper portion of the structure projects out of a liquid in use. This allows for a user to conveniently grip the package thereby facilitating stirring of the liquid and/or removal of the package from the Kquid. Usually this portion will be continuous and uniform with the remainder of the structure with the exception that it may be desirable to affix a tag thereto.
- This tag may function to provide a more suitable surface for gripping and/or as an indicia means. Such indicia may be used to identify the product or carry advertising or the like.
- the tag maybe affixed to the structure as a single planar sheet. In a preferred form, the sheet may be folded so that it presents opposing planar surfaces arrayed about the structure. This preferred form provides two separate surfaces for carrying indicia as well as providing more convenient gripping surfaces.
- Fig. 1 is a top plan view of a first embodiment of a tea package of the invention
- Fig. 2 is an inverted plan view of the tea package of Fig. 1;
- Fig, 3 is an end section view of the tea package of Fig. 1;
- Fig. 4 is top plan view of a second embodiment of a tea package of the invention.
- Fig. 5 is an inverted plan view of the tea package of Fig. 4.
- FIG 1 there is shown one embodiment of a tea package 10 of the invention. Note that in the description that follows, like parts bear the same reference numerals.
- the tea package 10 comprises a tubular structure 17 which contains tea leaves in an amount of about 5-7 g.
- the tea leaves cannot be seen in the figures.
- the structure has been heat sealed.
- a quantity of tea leaves has been filled into the structure and the water permeable paper has been dimensioned so that in cross section, the structure approaches a circular shape. This is best seen in figure 3.
- the tea package 10 is symmetrical about its longitudinal axis.
- Opposing surfaces 15 and 16 are substantially similar in configuration. By virtue of the amount of tea filled into the structure and the dimensions of the paper used, the opposing surfaces 15 and 16 bulge outwardly towards the centre of the package and then slope towards each other where the surfaces are heat sealed at ends 13 and 14.
- FIG. 11 The lower portion of the structure generally shown as 11 constitutes that part of the package 10 that would normally be immersed in boiling water. Likewise, the upper portion generally shown as 17 would be used for gripping the package.
- FIGS 4 and 5 there is shown a second embodiment of the invention.
- the features of this embodiment are identical to the first embodiment with the exception of the addition of a tag 21 to the heat sealed upper end 14.
- This tag 21 is formed of cardboard which has been folded over sealed end 14 to provide two surfaces for bearing indicia.
- the tag has been affixed to the structure by an adhesive apphed to one inside surface of the tag.
- the tag could have been affixed by a single staple passing through both surfaces of the tag and sealed end 14.
