Abstract
Abstract A telescoping container comprising a bottom section having a bottom wall and a plurality of side walls normal to the bottom wall and a cover section having a top wall and a plurality of side walls normal to the top wall; the side walls of the cover section extending on the outside of the corresponding side walls of the bottom section. A flap is externally secured to each of a pair of outer walls of the bottom section and a corresponding flap on corresponding walls extends inwardly of the cover section; this pair of flaps on the inner walls of the cover section passes the corresponding flaps on the outer walls of the base member when the cover section is placed on the bottom section and interlocks when the cover section is withdrawn. The top and bottom walls are caused to be bowed concavely. The bowing of these walls exerts outward forces on the interlocking flaps which, in turn, improves the locking action of the flaps when the cover section is fully extended from the bottom section. The cover member is provided with openings which will make the interior accessible to insects seeking out an insecticide and an attractant placed therein. The size of the openings in the cover section may be adjusted by vertical movement of the cover section to control the degree of exposure of the interior material as, for instance, when the interior material constitutes an air freshener either used alone or in connection with the insecticide.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
335 words
A telescoping container comprising two sections, each of the sections having a transverse wall, a pair of side walls and a pair of end walls normal to the transverse wall and an open end at the end opposite the transverse wall, one of said container sections having a dimension such that it may be slid over and receive the other section; the two sections being telescopically arranged with respect to each other with the open end of one section receiving the open end of the other section and the transverse walls being on the outside and parallel to each other so that said sections may be telescoped one within the other from a maximum dimension wherein said transverse walls are farthest from each other to a minimum dimension wherein said transverse walls are closest to each other; a pair of flaps at the edges of the end walls of the section which is received within the other section bent back into surface-to-surface relation with the outer surface of said end walls; a pair of flaps on the edges of the corresponding end walls of the outer section being bent inwardly to surface-to-surface relation with the inner suface of said end walls; said sections, when telescoping together, being so arranged that said flaps may interengage when the sections are pulled apart to their maximum dimension; the interengagement of said flaps when the telescoping sections are pulled apart preventing the outer section from being withdrawn from the inner section, and at least said side walls being connected to each of the transverse walls of each of the container sections by convexly curved fold lines; said curved fold lines causing at least said side walls to curve outwardly to provide a container section which is at least in part cylindrical in shape; said two container sections forming said telescoping container being similarly curved; said curved fold lines further causing said transverse wall in each of said container sections to curve concavely thereby facilitating the interengagement of said flaps.
Claim 2
Dependent Claim
335 words
A telescoping container comprising two sections, each of the sections having a transverse wall, a pair of side walls and a pair of end walls normal to the transverse wall and an open end at the end opposite the transverse wall, one of said container sections having a dimension such that it may be slid over and receive the other section; the two sections being telescopically arranged with respect to each other with the open end of one section receiving the open end of the other section and the transverse walls being on the outside and parallel to each other so that said sections may be telescoped one within the other from a maximum dimension wherein said transverse walls are farthest from each other to a minimum dimension wherein said transverse walls are closest to each other; a pair of flaps at the edges of the end walls of the section which is received within the other section bent back into surface-to-surface relation with the outer surface of said end walls; a pair of flaps on the edges of the corresponding end walls of the outer section being bent inwardly to surface-to-surface relation with the inner suface of said end walls; said sections, when telescoping together, being so arranged that said flaps may interengage when the sections are pulled apart to their maximum dimension; the interengagement of said flaps when the telescoping sections are pulled apart preventing the outer section from being withdrawn from the inner section, and at least said side walls being connected to each of the transverse walls of each of the container sections by convexly curved fold lines; said curved fold lines causing at least said side walls to curve outwardly to provide a container section which is at least in part cylindrical in shape; said two container sections forming said telescoping container being similarly curved; said curved fold lines further causing said transverse wall in each of said container sections to curve concavely thereby facilitating the interengagement of said flaps.
Claim 3
Dependent Claim
29 words
The telescoping container of claim 1, wherein the pair of flaps on the outer wall of the inner section are secured to said outer wall of said inner section.
Claim 4
Dependent Claim
61 words
The telescoping container of claim 2, wherein the pair of flaps on the inner surface of the end walls of the outer section are resiliently biased toward the end wall of the inner section; said last mentioned pair of flaps engaging the edges of said first mentioned pair of flaps when the telescoping container is pulled apart to its maximum dimension.
Claim 5
Dependent Claim
46 words
The telescoping container of claim 1, wherein at least one opening is provided in a wall of one of said sections; said opening being closed when the container is telescoped to its minimum dimension and being opened when said container is telescoped to its maximum dimension.
Claim 6
Dependent Claim
48 words
The telescoping container of claim 1, wherein a plurality of openings is provided in walls of one of said sections; said plurality of openings being closed when said telescoping container is collapsed to its minimum dimension and being open when said container is extended to its maximum dimension.
Claim 7
Dependent Claim
49 words
The telescoping container of claim 1, wherein a plurality of openings is provided in all of the walls of one of said sections; said openings being closed when said telescoping container is collapsed to its minimum dimension and being open when said container is extended to its maximum dimension.
Claim 8
Dependent Claim
48 words
The telescoping container of claim 1, wherein a plurality of openings is provided in the walls of the outer section, said plurality of openings being closed when said telescoping container is collapsed to its minimum dimension and being open when said container is extended to its maximum dimension.
Claim 9
Dependent Claim
38 words
The telescoping container of claim 4, wherein said opening may be fully closed and selectively partially closed and partially opened in accordance with the degree to which said telescoping container is positioned between said minimum and maximum dimensions.
Claim 10
Dependent Claim
27 words
The telescoping container of claim 1, wherein a cylindrical element is contained within said telescoping container being secured to a transverse wall of one of said sections.
Claim 11
Dependent Claim

The telescoping container of claim 1, wherein a cylindrical element is contained within said telescoping container being secured to a transverse wall of said inner section.
Claim 12
Dependent Claim
50 words
The telescoping container of claim 4, wherein insecticidal material is included in said container and the interior of said container is available for entry of insects when said opening becomes accessible to the interior of the container on movement of the two sections of the container toward its maximum dimension.
