- This application is a division of U.S. patent application Ser. No. 12/981357, filed Dec. 29, 2010, which claims the benefit of U.S. Provisional Patent Application No. 61/290851, filed Dec. 29, 2009, the entire disclosures of which are incorporated herein by reference.
- Slugs, snails, and other gastropod mollusks consume plant matter and are a major cause of plant and crop damage, both in home gardens and in agriculture. Traditional methods of slug and snail control include the use of salt, toxic bait, traps, and electrical barriers. However, these traditional methods have certain limitations. Salt and toxic bait remain effective for only a limited period of time before they disperse into the environment. Traps are cumbersome and must be emptied regularly. Electrical barriers are complex, costly, and require a significant amount of maintenance. Thus, there exists a need for a physical barrier for deterring or preventing slugs and snails from entering an area, such as a garden or farm, where plants are vulnerable to predation.

FIG. 5 is a sketch showing a perspective view of a mollusk barrier with C-shaped projections and separable spikes; -
FIG. 6 is a sketch showing a perspective view of the mollusk barrier secured to the ground with C-shaped clips; -
FIGS. 7A , 7B and 7C are sketches showing a planter with an integrated mollusk barrier and optional handles in accordance with the teachings of the present invention; -
FIG. 8 is a sketch showing a planter with an integrated mollusk barrier; -
FIG. 9 is a sketch showing a removable handle for a planter; -
FIG. 10 is a sketch showing a removable handle for a planter; -
FIG. 11 is a sketch showing a planter with a foam carrying device; and -
FIG. 12 is a sketch showing a planter having a base with an integrated mollusk barrier. - A barrier for deterring gastropod mollusks, such as slugs and snails, is disclosed. The mollusk barrier can be used for deterring slugs and snails from entering a protected area. For example, a user can position the mollusk barrier around a single plant, a group of plants, or an entire garden or farm. Alternatively, the mollusk barrier of the present invention can be integrated into a stand-alone planter or plant pot.
- The mollusk barrier may be used without traditional slug and snail repellants, such as salt and toxic bait, electrical barriers, and traps. Moreover, the mollusk barrier can be cut to a desired length and is easily bendable to conform to a desired profile. Thus, the mollusk barrier is customizable and provides the user with maximum flexibility in how the barrier is configured and where the barrier is placed.
- A
mollusk barrier 100 in accordance with the teachings of the present invention is shown inFIG. 1 . Themollusk barrier 100 has an elongatetubular support 110 having a plasticallydeformable core member 112 and anouter sheath 114. A plurality of closely-spaced outwardly extendingprojections 116 are attached to thetubular support 110. Theprojections 116 are spaced circumferentially and longitudinally along thetubular support 110 to define a barrier. In one embodiment, the largest spacing between neighboringprojections 116 is about ⅛ of an inch. However, it should be appreciated that the largest spacing between neighboringprojections 116 could range from about 1/25 of an inch to about ⅛ of an inch. AlthoughFIG. 1 shows theprojections 116 of thebarrier 100 positioned with somewhat random placement and orientations, it will be readily appreciated by persons of skill in the art that theprojections 116 may alternatively be provided in a more orderly configuration, for example in one or more rows wherein all of theprojections 116 are substantially parallel, e.g., in a comb-like manner. - The plastically
deformable core member 112 may comprise a metal wire, for example, a copper wire. Thecore member 112 is sufficiently flexible that a user can plastically deform themollusk barrier 100 into a desired shape. Thecore member 112 is also sufficiently rigid that it retains the desired shape. In a current embodiment theouter sheath 114 of themollusk barrier 100 comprises polypropylene. It is also contemplated that theouter sheath 114 of themollusk barrier 100 may incorporate a repellent, for example, copper particles or a chemical repellent. Theouter sheath 114 may have one ormore openings 113 that expose thecore member 112. When thecore member 112 is a copper wire, for example, the exposed portion of thecore member 112 provides an additional deterrent to slugs and snails that are repelled by contact with copper metal. The overall diameter of the elongatetubular support 110 can vary depending on the needs of the gardener or farmer. - The
mollusk barrier 100 has afirst end 118 and asecond end 120. Thefirst end 118 andsecond end 120 of themollusk barrier 100 are releasably connectable so that two ormore mollusk barriers 100 can be joined together. Thefirst end 118 andsecond end 120 can be joined together by any traditional means, for example, a hook and loop closure, ball and socket connector, snaps, screws, male and female connectors, adhesives, or the like. -
FIG. 2 is a sketch showing a perspective view of a second embodiment of amollusk barrier 200 that is similar to themollusk barrier 100, but with arcuately-shapedprojections 217. The arcuate shape of theprojections 217 deters slugs and snails while allowing themollusk barrier 200 to be handled by a user without causing substantial discomfort, or even injury, from theprojections 217. Whereas linear projections could puncture a user's hand,arcuate projections 217, such as those shown inFIG. 2 , can be handled without discomfort. -
FIG. 3 is a sketch of twomollusk barriers 200 being joined together in an end-to-end configuration. InFIG. 3 , thesecond end 220 ofmollusk barrier 200 on the left is joined to thefirst end 218 ofmollusk barrier 200 on the right. - A
mollusk barrier 200 can be secured to a substrate, such as the ground, in different ways. For example,FIG. 4 shows amollusk barrier 200 similar to a mollusk barrier shown inFIG. 2 but having a plurality of outwardly-extendingspikes 222 that are attached to thetubular support 210. Thespikes 222 are spaced longitudinally along thetubular support 210, and can be inserted into the ground to retain themollusk barrier 200 in a desired position or location. As seen most clearly inFIG. 5 , amollusk barrier 200 may include a plurality of C-shapedreceivers 224 attached to thetubular support 210 and oriented substantially longitudinally along thetubular support 210, eachreceiver 224 defining a through-hole 226 through which thespike 222 is inserted. Thespikes 222 are driven into the ground to prevent themollusk barrier 200 from being displaced. In this embodiment thebarrier 200 includes a single row ofarcuate projections 217. - Yet another way of securing the mollusk barrier to the ground is shown in
FIG. 6 wherein amollusk barrier 200 is attached to the ground with a plurality of C-shapedretainers 230. The C-shapedretainers 230 are placed over themollusk barrier 200 and can be inserted at desired intervals along the length of themollusk barrier 200. Although theexemplary retainers 230 shown inFIG. 6 are illustrated as generally symmetrical with parallel legs, it will be readily apparent to persons of skill in the art that theretainers 230 may be alternatively shaped. For example, the retainers may have a shorter leg on one side, such that only one leg is pushed into the ground, while the remaining portions extend over and around thebarrier 200. Moreover, the over extending portion may be curved to generally conform with the shape of thebarrier 200, and/or may have an inward extension or bulge at the distal end to more securely retain thebarrier 200. Similarly, the leg extending into the ground may be curved to be generally parallel to the outer boundary of thebarrier 200. - The

mollusk barrier mollusk barrier mollusk barrier mollusk barrier 100 to a desired length. Themollusk barrier mollusk barrier mollusk barrier mollusk barrier - In one aspect, the invention relates to a planter having an integrated mollusk barrier.
FIGS. 7A , 7B, and 7C are sketches showing aplanter 300 with anintegrated mollusk barrier 312. Referring toFIG. 7A , theplanter 300 includes aplant pot 301 and a plurality of outwardly or downwardly extending pointed projections that are affixed to theplant pot 301 and that define thebarrier 312. Themollusk barrier 312 is spaced vertically and horizontally to define a belt around theplant pot 301. As shown inFIG. 7A , themollusk barrier 312 encircles theplant pot 301. Themollusk barrier 312 can be located near the upper portion of theplant pot 301 as shown inFIG. 7A . Themollusk barrier 312 may alternatively be located the middle portion ofplant pot 301 or the lower portion of theplant pot 301. Although theplanter 300 is depicted as having a rectangular-shapedplant pot 301, it should be appreciated that the plant pot may be alternatively shaped, e.g., round or oblong. For example,FIG. 8 is a sketch showing aplant pot 341 with abelt 343. Thebelt 343 has a plurality of projections defining amollusk barrier 342 that are spaced vertically and horizontally around thebelt 343. - It will be appreciated by comparing, for example,
FIG. 5 withFIGS. 7A and/or 8 that a mollusk barrier may be configured as a separable member, for example an elongate flexible barrier similar to barrier 200 (FIG. 5 ), that is configured to attach to a planter such as planter 300 (FIG. 7A ). Such a flexible barrier may be reconfigured for use with a planter of arbitrary shape. In particular, the barrier may be made with a formable core, and may be cut to length or combined end to end with a other barriers, to fit a particular planter. For example, the barrier may be provided with a U-shaped inner rim to hook over the top of the planter, or with a plurality of discrete elements similar tospikes 222, or the like. Such separable barrier may be placed on the edge of the planter, or on the edge of a water catcher (not shown) disposed under the planter, to prevent mollusks from climbing into the planter. It will also be appreciated that the pointed projections that define the mollusk barrier can be arcuately shaped and have tapered tips oriented in a substantially downward direction. The downward orientation of the tips deters slugs and snails from climbing up from the base of the planter. - When the
planter 300 is in use, it is generally desirable for the projections to be exposed. However, when theplanter 300 is not in use, it may be desirable to transport the planter with a pair of handles or to cover the projections with a covering to prevent injury to the user. The handles and/or covering can be sold with the planter or sold separately. - A pair of
handles 350 for use with theplanter 300 is shown inFIGS. 7B and 7C . Thehandles 350 may haverecesses 354 to receive the pointed projections defining themollusk barrier 312 of theplanter 300. Thehandles 350 is shaped withrecesses 352 along a lower edge to accommodate the user's hand. Thehandles 350 are suitable for use with a square-shaped or rectangular-shapedplant pot 301.FIG. 7C is a sketch that shows thehandles 350 installed on aplanter 300. In the current embodiment therecess 352 is shaped with angled end portions to receive facilitate slidably engaging themollusk barrier 312. - Another handle 370 for use with a planter is shown in
FIG. 9 . Thehandle 370 is suitable for use with a round-shaped planter (not shown). Generally speaking, the handles can be made of either a flexible material, such as foam, or a firm material, such as polymeric resin. The handles can also be made from a combination of these materials. Thehandle 370 depicted inFIG. 9 has asoft foam interior 372 and a hard or morerigid resin exterior 374. Alternatively, thesoft foam interior 372 may be omitted to leave an open channel for receiving the barrier. Although recesses are shown in two opposed locations on thehandle 370, it will be appreciated that alternatively the handle may be configured with recesses along the entire lower edge of thehandle 370.FIG. 10 is a sketch showing ahandle 380 for use with a rectangular-shaped planter (not shown) that has asoft foam interior 382 and ahard resin exterior 384. As noted above, thebarrier 312 may be formed as a separable member that is attached to the planter. For example, the barrier may be elastically stretchable (for example by adding one or more elastic members, such as surgical tubing) such that the barrier can be stretched over a planter and retained elastically. - An
alternative carrying device 390 that is suitable for use with theplanter 300 is shown inFIG. 11 . The carryingdevice 390 is a flexible foam section that can be wrapped around aplanter 300 and used to transport theplanter 300. - A
planter 400 comprising aplant pot 441 having a separable tray orbase 410 withbelt 443 is shown inFIG. 12 . Of course, thetray 410 may have a larger diameter than theplant pot 410. Thebelt 443 has a plurality of projections defining amollusk barrier 442 that are spaced vertically and horizontally around thebelt 443. - While the preferred embodiment of the invention has been illustrated and described, it will be appreciated that various changes can be made therein without departing from the spirit and scope of the invention.
