Abstract
Abstract The disclosure relates to a modular tower-like structure for displaying merchandise for point of purchase sale. The basic tower is formed of cylinders of a plastic sheet material, such as clear "rigid" die cut vinyl plastic, of a thickness enabling it to be collapsed into a relatively flat form for shipping and storage. The sheet plastic tower elements are given a rigid cylindrical form by means of molded plastic end rings, which are of a channel-like cross sectional configuration to lockingly receive the ends of the cylinders. The end rings are of a form and configuration enabling two of them to be bonded in back-to-back relation, providing a structural interlock between the top of one tower module and the bottom of a second tower module above it. The structure is simple, inexpensive, conveniently packaged and shipped, and easily assembled at the display site.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
174 words
A multi-story tower structure for the display and dispensing of articles of merchandise which comprises, (a) a plurality of cylindrical tower modules formed of clear transparent sheet-like plastic material having characteristics of substantial dimensional stability and at least sufficient flexibility to be capable of being pressed relatively flat, (b) connecting ring formed of relatively rigid material and having opposed oppositely directed axially opening annular recesses of short axial length in relation to the axial length of said tower modules, (c) a pair of said tower modules being received in and end portions thereof being lockingly engaged with said annular recesses to define a multi-story tower structure having a continuous tubular interior for the reception of display merchandise or the like, (d) generally circular bottom-forming means removably supported in one of said tower modules, (e) one of said tower modules having a merchandise access opening therein at a level above said bottom-forming means, (f) a merchandise dispensing spout extending outward and upward from said access opening to enable removal of display merchandise from said structure.
Claim 2
Dependent Claim
174 words
A multi-story tower structure for the display and dispensing of articles of merchandise which comprises, (a) a plurality of cylindrical tower modules formed of clear transparent sheet-like plastic material having characteristics of substantial dimensional stability and at least sufficient flexibility to be capable of being pressed relatively flat, (b) connecting ring formed of relatively rigid material and having opposed oppositely directed axially opening annular recesses of short axial length in relation to the axial length of said tower modules, (c) a pair of said tower modules being received in and end portions thereof being lockingly engaged with said annular recesses to define a multi-story tower structure having a continuous tubular interior for the reception of display merchandise or the like, (d) generally circular bottom-forming means removably supported in one of said tower modules, (e) one of said tower modules having a merchandise access opening therein at a level above said bottom-forming means, (f) a merchandise dispensing spout extending outward and upward from said access opening to enable removal of display merchandise from said structure.
Claim 3
Dependent Claim
61 words
A multi-story tower structure according to claim 1, further characterized by (a) said connecting ring having a plurality of wedge-like locking lugs spaced circumferentially thereabout and projecting radially into said annular recesses, (b) said tower modules having cut-out openings therein in the end margins received in said recesses, (c) said cut-out openings being spaced for interlocking registry with said locking lugs.
Claim 4
Dependent Claim
37 words
A multi-story tower structure according to claim 2, further characterized by (a) said connecting ring having openings therein adjacent said locking lugs providing limited access to said tower modules for effecting release thereof from said connecting rings.
Claim 5
Dependent Claim
53 words
A multi-story tower structure according to claim 1, further characterized by (a) said connecting ring comprising a pair of like, annularly recessed ring elements joined back to back in axial alignment, and (b) additional like ring elements being mounted at the upper and lower extremities of said tower structure and forming capping rings.
Claim 6
Dependent Claim
99 words
A multi-story tower structure according to claim 4, further characterized by (a) said ring elements being formed of a relatively rigid plastic material, (b) said annular recess being defined by inner and outer ring walls and being of substantially greater width than the wall thickness of said tower modules, (c) said ring having a plurality of angularly spaced integral guide ribs extending radially from one of said walls, (d) said locking lugs extending from the other of said walls, (e) said guide ribs and said other wall defining a confined annular space for the reception of said tower modules.
Claim 7
Dependent Claim
31 words
A multi-story tower structure according to claim 5, further characterized by (a) pairs of said guide ribs being positioned in closely straddling relation to at least certain of said locking lugs.
Claim 8
Dependent Claim
68 words
A multi-story tower structure according to claim 6, further characterized by (a) said ring elements having a closed end construction including symmetrically arranged annular rib and channel elements, (b) said rib and channel elements being adapted to interfit when a pair of ring elements is assembled in back to back relation, (c) said connecting ring comprising a pair of such ring elements bonded together in such assembled relation.
Claim 9
Dependent Claim
67 words
A multi-story tower structure according to claim 1, further characterized by (a) said merchandising dispensing spout being formed of sheet-like plastic material similar to that of the tower modules and being formed to have sidewalls and an inclined outer wall, (b) said sidewalls being creased to accommodate bellows-like folding thereof, enabling a closing of said spout for shipping and/or storage of the component parts of said structure.
Claim 10
Dependent Claim
47 words
A multi-story tower structure according to claim 1, further characterized by (a) said sheet-like plastic material of which said tower modules are formed having properties characteristics of rigid polyvinylchloride, and (b) said connecting ring being injection molded of a material having properties characteristics of high impact polystyrene.
