DETAILED DESCRIPTION

As illustrated in FIG. 1, there is provided a container, which is generally indicated at 10, for holding therein liquids. The container 10 comprises an upper portion 12 for holding the liquid therewithin, and a base 14 disposed therebelow (together constituting a basic container structure, and separated in FIG. 1 with a broken line), on which the container stands when in an upright standing position.
The upper portion 12 may be of any suitable design, typically defining thereby the function of the container 10. For example, in the example illustrated in and described with reference to FIG. 1, the upper portion 12 comprises a circumferential sidewall 16 defining a liquid-containing space 18. It will be appreciated that even though a container according to the presently disclosed subject matter may be described as comprising several sidewalls, for example wherein the container has a square shape, the term “sidewall” is used herein to refer to all sidewalls collectively, unless otherwise clear from context.
The sidewall 16 may have a substantially cylindrical shape (as illustrated), or have any other suitable shape (e.g., having a square, hexagonal, etc., cross-section, being cylindrical, etc.), and are formed with an upper opening 20. As the opening 20 of the container 10 illustrated in FIG. 1 is similar in size to the cross-section of the sidewalls, the container may function as a cup. According to other examples, the sidewall 16 may, at an upper end thereof, narrow to form a neck, thereby defining an opening 20 which is small relative to the cross-sectional size of a lower portion of the sidewall, wherein the container may function as a bottle.
The base 14 is disposed below the upper portion 12. It is made of a non-opaque, i.e., transparent (including colored, as described above) and/or translucent, material. It may be formed as a single, unitary element therewith. (Accordingly, it will be appreciated that references in this disclosure to features and/properties of the base 14 may similarly apply to the upper portion 12 of the container.) It may be made of any suitable material, including, but not limited to, glass, plastic, etc. An outer surface 22 thereof may be formed so as to smoothly merge with an outer surface 24 of the sidewall 16 of the upper portion 12. As better illustrated in FIGS. 2A and 2B, a bottom side 26 thereof is formed with an inner surface 28, defining a downwardly-facing concavity 30 within the base 14. The concavity 30 may be circularly symmetric.
A plug 32, having an upper surface 34 shaped correspondingly to the inner surface 28 of the base 14, is provided, disposed within the concavity 30 and substantially filling it. It is made of a non-opaque, i.e., transparent and/or translucent, material, for example which may be molded at a temperature which is significantly lower than that at which the material of the base 14 may be molded. The material has optical properties which are substantially similar to the base 14. For example, the refractive indices of the base 14 and the plug 32 may be substantially the same, such that when the plug is the same color as the base and is received within the concavity 30 (for example as described below), it appears to be constitute a unitary element of the base (e.g., at least when examined perfunctorily and/or from certain angles, such as from above, i.e., through the liquid-containing space 18), i.e., the base appears “solid,” i.e., to be formed without the concavity 30. It will be appreciated that the optical properties may be considered to be substantially similar, for example if the appearance of the plug 32 within the base 14 is similar, e g, at least when examined perfunctorily, to that of a plug and base wherein the optical properties are exactly the same, even if there is a small measurable difference therebetween.
According to some examples, the plug 32 is made of a suitable material, for example an epoxy, an acrylic, a polymer such as polyester or polyurethane, or a combination of two or more of the above. The material of the plug 32 may be selected based its optical properties, e.g., its similarity to those of the material of the base 14.
The upper surface 34 of the plug 32 sealingly contacts the inner surface 28 of the base 14, i.e., it fully abuts it without leaving any visible gaps therebetween, at least along a portion of the interface between the two surfaces. According to some examples, the upper surface 34 of the plug 32 sealingly contacts the inner surface 28 of the base 14 along a majority of the interface therebetween. According to other examples, the upper surface 34 of the plug 32 sealingly contacts the inner surface 28 of the base 14 along substantially the entire interface therebetween.
According to some examples, e.g., as illustrated in FIG. 3, a bottom surface 36 of the plug 32 is substantially coplanar with a bottom 38 of the base 14, together constituting a uniform bottom of the container 10. The container 10 may contain a downwardly-facing circular ridge 40, defining therewithin a depression 42 on the bottom of the container. The ridge 40 may be formed on the plug 32 as illustrated, and/or on the base 14.
The container 10 further comprises an article 44 disposed within the concavity 30 of the base 14. Accordingly, it is visible through the plug 32 and/or base 14, as seen in FIG. 1. The article 44 may be decorative and/or functional, for example as described below.
According to some examples, the article 44 is disposed within the plug such that it is encased therewithin. According to other examples, it is disposed at least partially between the inner surface 28 of the base 14 and the plug 32 (whereby the plug encases it within the concavity 30; in such a case, the upper surface 34 of the plug may sealingly contact all portions of the inner surface of the base not in contact with the article 44). The article 44 may comprise a pressure-sensitive adhesive, with which it is at least partially attached to the inner surface 28 of the base 14.
According to some examples, e.g., as described above, wherein the refractive indices of the base 14 and plug 32 are substantially the same, the article appears to “float” within the “solid” base. Typically, the article 44 is made of a material which is likely to be damaged or destroyed at temperatures required for forming the base 14, but not at temperatures required for forming the plug 32.
Providing the base 14 and plug 32 as described above (e.g., different materials having similar optical properties) may facilitate providing the article 44 such that it appears to be encased within a solid base of a container. In addition, it facilitates providing the article 44 such that it is visible but not physically exposed, for example allowing the container 10 to be exposed to conditions (e.g., cleaning with hot water, soap, chemicals, etc.) unsuitable for the article 44, without risk of damage to the article.
The article 44 may be provided with an image printed thereon. The image may face downwardly, for example allowing identification of the container 10 from the bottom, or upwardly, for example allowing viewing thereof via the liquid-containing space 18 of the upper portion 12 (for example when the container is a drinking cup). The image may comprise a barcode, which may be a one-dimensional barcode and/or a two-dimensional barcode.
The article 44 may comprise one or more elements which are configured to alter their appearance correspondingly to a change in temperature. For example, the article may be used to provide a visual indication of the temperature of a liquid within the liquid-containing space 18 of the upper portion 12.
The article 44 may a power supply, which may comprise a power source and a wireless power receiver, for example an inductive receiver, a resonant inductive receiver, a capacitive receiver, or a magnetodynamic receiver, facilitating recharging of the power source while limiting the physical exposure thereof. The article 44 may further comprise a light source powered by the power supply, such as a light emitting diode (LED) and a controller, for example configured to selectively control the color of light emitted by the LED.
The article may comprise one or more electronic components configured to facilitate detection by an external electronic circuit. The component may comprise a radio frequency identification tag.
As illustrated in FIG. 4, there is provided a method, which is generally indicated at 100, for manufacturing a container, for example as described above. In step 110, a a basic container structure is provided. The basic container structure comprises an upper portion having a circumferential sidewall defining therewithin a liquid-containing space, and a base made of a non-opaque material. The base is disposed below the upper portion and comprises an inner surface defining a downwardly-facing concavity. In step 120, an article is provided within the concavity. In step 130, a plug is molded within the concavity. The plug is made from a material characterized by one or more optical properties which are substantially similar to that of the base. The molding of the plug within the concavity is such that it sealingly contacts at least a portion of the inner surface thereof. Such a method may be used to manufacture a container as described above, i.e., wherein the article is visible through the plug and the base.
It will be appreciated that while the foregoing description relates to a container for holding liquids, it is only presented as an example, and one skilled in the art will readily recognize that it may be applied to other utensils, even those not designed for holding liquids. For example, a utensil such as a plate having a flat surface not suitable for containing thereon a liquid, but otherwise as per the above description, may be provided without departing from the scope of the presently disclosed subject matter, mutatis mutandis. Additionally, a container and/or utensil designed for holding something other than foodstuff, e.g., a vase, may be provided without departing from the scope of the presently disclosed subject matter, mutatis mutandis.
Those skilled in the art to which this invention pertains will readily appreciate that numerous changes, variations, and modifications can be made without departing from the scope of the presently disclosed subject matter, mutatis mutandis.
