Description

    FIELD OF THE INVENTION
  • The present invention relates to containers for solid or semi-solid products and in particular to plastic containers for holding and allowing freezing of juice products.
  • BACKGROUND
  • In particular markets there is a desire to purchase and take home frozen juice for later personal use. The product is supplied in a container in its frozen state and is retained in the frozen state until the juice is required. Typically the juice is of a concentrated form to be later diluted to the strength desired.
  • The typical process is that the end user would part defrost the frozen juice to remove the desired amount or would squeeze the container to extract the amount of frozen juice required.
  • Existing products, for example the ‘Minute Maid’ 12 oz Frozen Orange Juice container, have typically been made of paper with a plastic or foil lining having a tear off seal top and a re-closable lid. However, these containers have a number of disadvantages. When the container is crushed to remove the amount of juice required it is not easily returned to its pre-crushed shape. This can lead to inefficient resealing of the container and degradation of the product. Furthermore the container of these forms is not easily recyclable. It is also often difficult to crush the required amount of frozen juice out of the container. Further, a user cannot see the amount of product left in the container without at least opening the container.
  • In this specification where reference has been made to patent specifications, other external documents, or other sources of information, this is generally for the purpose of providing a context for discussing the features of the invention. Unless specifically stated otherwise, reference to such external documents is not to be construed as an admission that such documents, or such sources of information, in any jurisdiction, are prior art, or form part of the common general knowledge in the art.
  • It is therefore an object of the present invention to provide a container that at least goes some way to overcoming the disadvantages of the prior art or at least that will provide the public with a useful choice.

  • FIG. 9 shows a bottom elevation of the embodiment of FIG. 7.
  • Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.
  • The container 1 consists of a container upper portion or first portion 3 and a crushable container body portion or second portion 4. The first portion 3 is the uppermost portion the second portion 4 is the portion immediately below. The relative size of each of the portions is shown in the drawings but is indicative only. Depending from the first portion 3 is an outlet aperture 12 to the interior of the container 1, defined by an outlet spout or neck 11.
  • In the preferred embodiment this aperture 12 has neck 11 that is threaded to receive a resealable complementary re-sealable closure (not shown). In other embodiments the neck 11 and complementary closure may be press fit or use any other re-sealable system known in the art. The complimentary closure forms a liquid tight and preferably air tight seal to the container to prevent leaking and contamination of the container 1 contents. The neck 11 and complimentary closure in the preferred embodiment are formed to provide a tamper evident closure.
  • In the preferred embodiment there is a lower portion 5, depending from the second portion 4 that forms the bottom of the container 1. In other embodiments within the scope of the invention the second portion 4 may form the bottom of the container 1.
  • The second portion 4 consists of a number of lines of weakness 7 that define a plurality of facets 8. In the preferred embodiment these lines of weakness run parallel to the container axis 6. The resulting facet shape in the preferred embodiment is rectangular and eight such facets 8 are present. However the number of facets 8 present may vary from two to ten for example or maybe even more. The shape of the facets 8 may be triangular, square or more sided depending on the number and orientation of the lines of weakness 7. For example six sided facets may be present that tessellate to form the second portion 4. It is preferred that the major axis of the facets formed is parallel to the container axis 6.
  • The container 1 has a waist region 13 as a change in dimension at or near the interface of the second portion 4 to the first portion 3. This is evident as a change in diameter of the circle that would connect the apex points of each of the facets 8 in the container body portion or secondary portion 4 to that of the circle 24 that would connect the apex points of the container upper portion 4.
  • If a container base portion or lower portion 5 is present then there is also a waist portion 13 as a change in diameter (as described above) at or near the interface with the second portion 4. The waist portion 13 has a reinforcing function that increases hoop stiffness of the container 1 at or near the change in diameter. The reason for this will become clear shortly. In the preferred embodiment this change in diameter (described above) is perpendicular to the container axis 6.
  • In the preferred embodiment there is also an inward groove 9 at or near the interface of the second portion 4 to the first portion 3 and lower portion 5 (if present). The inward grooves 9 have a reinforcing function of the first portion 3 and lower portion 5.
  • In other embodiments the first portion 3 and lower portion 5 may have a waist portion 13 as an over hang or abutment over the second portion 4 as shown in FIG. 2. This over hang or abutment (indicated as 13) provides the reinforcing of the hoop stiffness at or near the interface of the second portion 4 to the first portion 3 and lower portion 5 (if present). The over hang or abutment 13 also provides a rub zone of the container 1 against other like containers and other surfaces. This prevents the majority of the container contacting other surfaces. In particular this will prevent any labelling being abraded or damaged due to rubbing or contact. The rub zone also acts as a guide during the filling process of the container 1.
  • In the most preferred form of the invention both the inward groove 9 and the waist portion 13 as an abutment or overhang are present as best shown in FIG. 8. This produces a container 1 that has rectangular facets 8 between the upper and lower grooves 9, whose major axis 17 is parallel to the container axis 6, ie the major axis of he facets between the grooves 9 is vertical. The facets 8 above and below the grooves 9, are either square or rectangular. When the facets 8 are rectangular their major axis, as can be seen, is orthogonal to the container axis 6, ie the major facet axis is horizontal or in other words their minor axis 18 is aligned or parallel to the container axis 6. This change in major axis orientation from between the grooves 9 to that above and below the grooves 9 further increases the hoop stiffness of the container 1. This results in a container that has better shape retention above and below the grooves 9 in the second portion 4. This again further prevents crushing of the first portion 3 and lower portion 5, whilst allowing the container body portion 4 to be crushed for example to expel the contents of the container 1.
  • The container 1 is to be filled with a semisolid product 2. In the preferred embodiment this semisolid product 2 is frozen or part-frozen fruit juice or a similar consistency product.
  • In the preferred use of the present invention the semisolid product is retained in its semisolid state (e.g. from the freezer). To remove the semisolid product 2 from the container 1 the user simply squeezes the second portion 4 to push the semisolid product 2 out the aperture 12. When squeezing the container 1 the user will in some way contract the second portion 4 of the container 1. They may do this by squeezing the second portion 4 directly or by twisting the container substantially about the container axis 6. Alternatively they may squeeze the container along the container axis 6. In any method where the internal volume of the container 1 is reduced to remove the semi-solid product, the lines of weakness 7 will allow a controlled crumpling of the second portion 4. Further more the change in diameter (due either or both to the inward groove 9 or the over hang or abutment 13) will confine this controlled crumpling to the second portion 4. Due to the lines of weakness 7 a crumpling of the second portion 4 is easily achieved that will expel the desired amount of semi solid product from the container 1.
  • The controlled crumpling and change in diameter improving hoop stiffness will prevent the majority of crumpling from proceeding into the first portion 3 or lower portion 5 (if present). This will have the effect of allowing the first portion 3 and lower portions 5 to retain their shape. This is important as it will allow ease of replacement of the complementary closure. Furthermore since the lower portion will retain its shape the container can be reliably rested on its base with no fear of the container 1 falling over and spilling its contents (if no longer semi-solid). The prevention of crumpling into these portions also reduces the risk of cracking and leaking out of the semi-solid product inside.
  • Thereafter the container 1 and contents is returned to the freezer. The extracted product is then used by the user, for example brought to a liquid state by application of heat (warm water or heating). The extracted product in its preferred embodiment is a concentrate that is then diluted (e.g. by water) down to the desired strength.
  • In another embodiment the user may heat (e.g. in a microwave) the entire container 1 up to liquefy the contents and then the contents can be extracted. Thereafter the user returns the container 1 to the freezer. In this application the facets 8 formed actually act to strengthen the container 1 parallel to the container axis 6 (“axial strength”) and prevent it collapsing should the container I material soften from application of heat. In practise the container 1 will sit on the lower most surface of lower portion 5 in a vertical orientation (i.e. with aperture 12 open vertically upwards). Any heating the container 1 or content experiences may soften the material of the container 1. In such an orientation the facets 8 provide increased axial strength against vertical buckling or bowing out of the second portion 4 due to the self weight of the container 1 or its contents.
  • In the preferred embodiment the container 1 is made from plastic and preferably a clear plastic so the contents can be easily viewed. The container 1 may have writing or information printed directly on it, or may have a label adhesively or fixedly applied (e.g. by shrinking a label around the portions). In the preferred embodiments the labelling is located between upper and lower abutments or over hangs 13.
  • The bottle and/or cap of the present invention can be formed from a plastic material such as, but not limited to, high density polyethylene, low density polyethylene, poly vinyl chloride and polyethylene terephthalate (PET). Desirably the plastic material is microwave and freezer safe. Preferably the bottle is made of PET.
  • The bottle and/or cap of the present invention can be formed using known in the art plastic forming processes such as injection stretch blow moulding, thermoforming, rotary moulding and vacuum moulding among others. Preferably the bottle is formed by injection stretch blow moulding.
  • Whilst the term frozen or semi-frozen has been used here it is to be understood that any product that is semisolid (whether at room temperature or not) can be utilised.
  • The foregoing description of the invention includes preferred forms thereof. Modifications may be made thereto without departing from the scope of the invention.
