2 Claims. 1
The invention relates to improvements in containers and more particularly to a novel thermocontainer of paper material embodying structural features adapting easily assembled interior and exterior containers to ready disassembly for use of either portion thereof independently of the other.
It is common practice, when serving a hot or cold beverage for example, to put the beverage in a container or cup of paper material. Such practice does not take into account the fact that a temperature change in the contents occurs veryrapidly owing to the lack of any thermoinsulating properties in the thin walls of the paper container. Thus, hot beverages cool rapidly and cold beverages become tepid very soon after being placed in the container, especially under temperature conditions existing when such beverages are in greatest demand. Also, the serving of hot beverages in athin wall container is disadvantageous because of the difficulty and inconvenience of handling.
The invention therefore has the purpose of overcoming the aforementioned disadvantages arising from the use of known types of paper containers. To this end a double-walled container of paper material is provided which includes means for sealing the contents within an interior container and sealing the sealed interior container within an exterior container in such manner as to provide dead air space or spaces entirely around the interior container. The invention is further characterized by a structure that permits the interior container to be easily and quickly inserted and secured in or separated and withdrawn from the exterior container without distortion of either container.
It is, therefore, an object of the present invention to provide a thermo-container of a kind that overcomes the disadvantages of use now present in containers of known construction.
Another object is to provide a thermo-container that is not too expensive to manufacture and which can be assembled easily and quickly by the beverage vendor.
Another object is to provide a thermo-container in which either or both the interior and exterior containers may be fabricated along the lines of conventional containers made of paper material and now in use and which are, therefore, capable of use independently one from the other.
Other and further objects of the present invention will be apparent from the following description and claims, and are illustrated -in-the accompanying drawings which, by -way of -illus tration, show exemplary embodiments and the principles thereof. Other embodiments of the inventionembodying the same principle may-be used, and structural changes may be made as, desired by those skilled in theart, without dc parting from the present invention and the purview of the appended claims.
In the drawings:
Fig. 1 is a longitudinal central sectional view through a thermo-container embodying features of the present invention.
Fig. 2 is a longitudinal central sectional view through a thermo-container embodying other features of the invention.
Figs. 3 and 4 are each longitudinal central sectional-views of different containers embodying other modified features-of the invention.
Throughout the disclosure, like numerals are used to identify corresponding parts.
Features of the present invention are applicable to several differenttypes of containers of paper material, including a type commonly referred to as the Dixie container. One such thermo-container utilizing a conventional type of Dixie container is illustrated in Fig. 1. As shown, the assembly includes an exterior cuplike container ll having-a bottom Wall "I2 and a cylindrical side wall I3. The cylindrical wall t3 preferably flares outwardly upwardly and is formed on its-peripheral-edge with an exterior circumferential beaded lip I l. A pair of axially spaced circumferential ribs l5 and [6 respectively are formed in the container wall below the lip l'zl. As shown, the ribs IB-and H5 protrude on the outside surface of the container wall 13 was to provide circumferential recesses l1 and 'larespectively on the inside wall surface. 1
The exterior container l [is arranged to receive entirely avithinits confines -an-interior container 21 which-includes a bottom 2-2 and a cylindrical wall '23. The cylindrical wall 23 terminates at its upper free edge in an external peripheral bead or lip -24-andit has, spaced -therebelow,- a circumferential external rib 25 defining an in ternal circumferential groove or recess 25.
In use, the interior container 2| is adapted to contain the beverage or other temperatureaffected-substance which is sealed therein' as by means of a circular cap 2-! of a kind that is pressed firmly downwardly into the open container mouth until its peripheral edge '-is engaged in "the internal circumferentialrecess 26. It isretained-inplace by such engagementuntil forcibly withdrawn. The filled mterior container 2| -is-contained-Within-the exterior c'ontai-nerll as shown. The interior container is suspended within the exterior container H in such manner that its wall and bottom are spaced from the wall and bottom of the exterior container so as to thereby define an air space 28 entirely surrounding the interior container.
Suspension of the interior container 21 within the exterior container H may be accomplished by means of an annulus 3| which has its outer peripheral edge firmly seated in the exterior container recess |8 as shown. The inner peripheral edge of the annulus 3| is of such circumference as to receive the interior container 2| snugly therein. As illustrated, the inner peripheral edge of the annulus 3| is nested snugly against the interior container wall 23 below the circumferential head or lip 24 in such manner that the lip 24 afiords means for suspending the interior container in position. Unintentional withdrawal or displacement of the interior container is avoided by the presence of the circumferential rib 25 on the interior container which is of sufficient outside dimensions to engage beneath the marginal inner peripheral edge of the annulus 3| tainer is suitably sealed as by means of a ciri cular closure cap 32 which has its peripheral edge seated snugly in the internal circumferential recess ll of the external container. This provides an additional dead air space 28 between the closure caps 21 and 32.
It should be quite evident at this time that the interior container is completely surrounded by dead air space which affords thermo means to prevent rapid temperature change in the contents thereof. If desired, all or some of the spaces 28 between the container walls may be filled with ice to thereby increase the thermal efiectiveness of the container for maintaining the contents of the interior container at a desired low temperature.
The construction described in detail hereinabove and illustrated in Fig. 1 clearly embodies the use of interior and exterior containers of substantially conventional construction and because each container is complete in itself, said containers may be used independently of each other.
Fig. 2 illustrates a slightly modified form of thermo-container wherein the interior container 21a is provided on its upper edge with an external peripheral lip or flange 33 of such outside dimension as to dispose its peripheral edge for engagement and snug seating in the internal recess |8 of the external container l3. This construction affords a structure whereby an air space or spaces 28 is provided entirely around the interior container and the number of parts required in the assembly is reduced to a minimum.
Fig. 3 illustrates a thermo-container embodying other features of the present invention. As illustrated, the interior container 2| is constructed like the interior container 2| of Fig. 1. The
exterior container ||a is provided, in the presbelow the annular rib l5. The protuberances 34 extend inwardly from the external container wall a distance Sllfficlel'lt to admit the interior container 2| for insertion of the latter into the exterior container in the manner shown. Such insertion of the interior container 2| locates the circumferential lip or head 24 of the interior container in abutment with the protuberances 34 whereby the interior container is held suspended. Inadvertent withdrawal or displacement upwardly of the interior container is avoided by means of the annular external rib 25 on the interior container, which frictionally abuts the bottom faces of the protuberances 34.
The thermo-container illustrated in Fig. 4 differs from the constructions previously described in that an external container 35 is provided, substantially midway of its height, with a plurality of circumferentially spaced inwardly struck protuberances 36 and a protuberance 3'! in its bottom wall 38. The protuberances 35 and 3! afford means for supporting the interior container 2| within and spaced from the wall and bottom of the exterior container. A closure cap 39, which has its peripheral margin seated in the circumferential internal recess H of the external container 35, also is provided with a protuberance 4| which extends downwardly therefrom and is of sufficient length to dispose its end substantially in contact with the top surface of the interior container closure 21. This engagement between the protuberance 4| and the interior container closure 21 prevents upward displacement of the interior container when the exterior container is closed and sealed by its closure cap 39. In this structure a dead air space or ice chamber 28 is provided entirely around the interior container 2|.
It should be quite evident at this time that applicants have provided a very inexpensive thermoccntainer embodying as its major parts containers constructed substantially like forms now in common use and that said thermo-container is highly efiicient inasmuch as a completely sealed-in dead air space is provided to prevent rapid temperature changes of the contents. It should be understood also that, although several embodiments of the invention have been disclosed herein, the invention is capable of embodying various modifications in detail construction without departing from the spirit of the invention or the scope of the appended claims.
1. An insulated container comprising, in combination, a thin walled external container having a pair of spaced apart circumferential grooves on the inside surface of its well adj acentits open top, an annulus having its outer peripheral margin seated in the lowermost of said grooves, a thin walled internal container insertable through said annulus, an external circumferential bead surrounding the mouth of the internal container and an external annular protuberance spaced below said bead to define an annular channel between the bead and protuberance, said annular external protuberance being of such outside diameter as to facilitate its forced passage through the annulus so as to dispose the inner peripheral edge of the annulus in said channel, and a cover for the external container peripherally engageable in the uppermost groove of the external container.
2. An insulated container comprising, in combination, a thin walled external container having a pair of spaced apart circumferential grooves on 5 the inside surface of its wall adjacent it open top, an annulus having its outer peripheral margin seated in the lowermost of said grooves, a thin walled internal container insertable through said annulus, an external circumferential bead surrounding the mouth of the internal container and an external annular protuberance spaced below said bead to define an annular channel between the bead and protuberance, said annular external protuberance being of such outside diameter as to facilitate its forced passage through the annulus so as to dispose the inner peripheral edge of the annulus in said channel, a cover for the internal container peripherally engageable in the internal groove formed by the annular protuberance therein, and a cover for the external container peripherally engageable in the uppermost groove of the external container.
