## Background
FIELD OF THE INVENTION
The present invention relates generally to the field of imprinting tools. Specifically, the present application relates to a tool for making decorative impressions in surfaces.
BACKGROUND OF THE INVENTION
Food decorators often create impressions of designs in media including buttercream, fondant, gum paste, modeling dough, and cookie dough. These designs may include alphanumeric characters, symbols, or ornamental embellishments to decorate food products. The decorator may use presses comprising press pieces to create designs on the surfaces of food products. It can be difficult to achieve the desired impressions in a precise and repeatable manner.
A problem with the current presses is that they do not allow decorators to create impressions without press pieces moving during use. In addition, the current presses and press pieces do not allow decorators to see through the presses while creating impressions. That is, the opacity of current presses and press pieces obscure the sightline of the decorator at critical times during decoration. The opacity of current presses and press pieces also requires decorators to estimate the approximate location and orientation of the impression. Correct placement of the impressions on media is challenging to achieve and cannot be ensured.
Current presses do not allow for the impression pieces to remain fixed in desired configurations without movement. Decorators must currently use great delicacy and care in lifting and turning such presses over to avoid moving the impression pieces. Decorators often use their fingers to help keep the impression pieces in place, which is further complicated by the difficulty in aligning the press for placement as noted above. Many current presses do not facilitate combining alphanumeric and non-alphanumeric designs together. Decorators currently approximate the location of impressions when combining alphanumeric and non-alphanumeric designs, resulting in imperfect borders and lines. Such imperfections often extend decoration time because they may require the decorator to remove the imperfect impression and start over.
A need exists for improved technology, including technology that may address the above described disadvantages.
SUMMARY OF THE INVENTION
One embodiment of the invention relates to an imprinter for creating impressions of designs. The imprinter includes a retainer having a retainer body and at least one retaining portion and a lock configured to be received by the retainer, the lock having a lock retaining portion engageable with the retaining portion of the retainer to selectably secure the lock to the retainer.

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and made part of this disclosure.
FIG. 1A illustrates an imprinter 100 that comprises a retainer 110 with retainer sides 113, a grip 119, at least one lock 150, which in one embodiment includes a first lock 150a and a second lock 150b at opposing ends 106 of the retainer. The imprinter 100 may be made of any suitable material, for example, plastic. The retainer 110 of the imprinter 100 may receive at least one press piece 180. The imprinter 100 may be any color. In addition, the imprinter 100 may be transparent or opaque, and the press piece 180 may be transparent or opaque. In a preferred embodiment, the imprinter 100 and at least one press piece 180 may be transparent. The press piece 180 may be made of any suitable material, for example, plastic. The retainer 110 and the press piece 180 may be made of different materials.
Referring now to FIGS. 1A-C, the imprinter 100 includes a retainer 110. The retainer 110 includes a retainer body 111. The retainer body 111 maybe substantially planar. Extending from the retainer body 111 are a first retaining portion 113a and a second retaining portion 113b. In one embodiment, the first retaining portion 113a extends from a first edge of the retainer body 111 parallel with the longitudinal axis of the retainer body 111. A second retaining portion 113b extends from a second edge, opposite the first edge, of the retaining body parallel with the longitudinal axis of the retainer body 111. The first retaining portion 113a and second retaining portion 113b may extend perpendicular to the plane of the retainer body 111. In one embodiment, each of the first retaining portion 113a and the second retaining portion 113b include a corresponding groove 114a, 114b for receiving a portion of the press piece 180. The grooves 114 may be formed as a recess in the respective first retaining portion 113a and second retaining portion 113b or may be formed by the presence of a flange on the respective first retaining portion 113a and second retaining portion 113b. 
Referring now to FIGS. 2A-D, in one exemplary embodiment, a press piece 180 includes a deck 181 having a design 182 extending therefrom and sides 183. The press piece 180 further includes a back surface 184 (illustrated in FIG. 2D). When the press piece 180 is assembled with the retainer 110, the back surface 184 is adjacent to the retainer body 111 and the design 182 extends away from the retainer 110. The press piece 180 includes a retained portion 183 that is configured to engage with the retainer 110 to hold the press piece 180 to the retainer 110. In one embodiment, the retained portions 183 are sides of the press piece 180 configured to slide into sides 113 of retainer 110. In one embodiment, the retained portions 183 may substantially fill the short axis (height) of the grooves 114 such that the press piece 180 may be removed from the retainer 110 but when engaged with the retainer 110 is snugly fit so as to prevent substantial movement vertically when the retainer 110 is operated.
The design 182 of FIG. 2A is alphanumeric. In another exemplary embodiment, the design 182 may be ornamental (see FIG. 2B). The press piece 180 is removable from the retainer 110 for easy cleaning and for customizing combinations of designs to be imprinted with the imprinter 100.
With reference to FIG. 1A, the first lock 150a and the second lock 150b are engageable with the retainer 110. The first lock 150a and the second lock 150b each includes a lock retaining portion 151 and a lock deck 152, which may be tab-shaped as shown in FIG. 3A. In one embodiment, the retainer 110 is attached to a grip 119 for use in positioning the imprinter 100 over a surface. The grip 119 assists decorators in imprinting the design 182 at precise locations and angles for decorating. The retainer 110 has sides 113 between which at least one press piece 180 may slide into the retainer 110. The lock deck 152 of first lock 150a and second lock 150b may be turned toward the design 182 to secure the press piece 180 in place. The first lock 150a and the second lock 150b are configured to slide between sides 113 of retainer 110 and are disposable at opposing ends 106 of the retainer 110.
The first lock 150a and the second lock 150b are configured to secure at least one press piece 180. The first lock 150a and the second lock 150b may be configured to release at least one press piece 180 and allow for movement within the retainer 110 and removal from the retainer 110. Placement of the first lock 150a and the second lock 150b on opposing ends 106 of the retainer 110 sandwiches at least one press piece 180 between the first lock 150a and the second lock 150b. When the lock deck 152 of each lock is oriented to project perpendicularly to the retainer 110, contents of the retainer 110 are unlocked and may shift slightly within the retainer 110 during imprinting. In a preferred embodiment, first lock 150a and second lock 150b are both locked to inhibit movement during imprinting and are unlocked to facilitate easy removal of the press piece 180 and easy insertion of the press piece 180 into the retainer 110.
The exemplary embodiments described above do not limit the types of designs that may be used in the imprinter 100. For example, other designs that may be used in conjunction with imprinter 100 include symbols, curlicues, embellishments, illustrations, adornments, and artwork. In one embodiment, the press piece 180 features a design 182 that is scroll-like (see FIG. 2B). Moreover, in other embodiments, impressions may be made of combinations of different types of designs.
Referring now to FIGS. 3A-B, the lock 150 includes a lock deck 152 and a lock retaining portion 151. In one embodiment, the lock retaining portion 151 is positioned at one end of the lock 150 and configured to engage the groove. In one embodiment, the lock retaining portion 151 comprises a cylinder. The lock retaining portion 151 may be a cylinder that extends at least the width of the lock deck 152 or may be in two parts with a first cylinder extending from one side of the lock deck 152 and a second cylinder extending from the other side of the lock deck 152. The lock retaining portion 151 comprises a major axis 158 and a minor axis 159, the major axis 158 corresponding to the longest diameter and the minor axis 159 to the shortest diameter.
In one embodiment, the major axis 158 is perpendicular to the plane of the lock deck 152. The major axis 158 is equal to or greater than the height of the groove 114 while the minor axis 159 is less than the height of the groove 114. Thus, the locking retaining portion 151 may slide along the groove 114 while the major axis 158 is not aligned perpendicular to the longitudinal axis of the retainer 110 (and its groove 114). The lock 150 may be slid into the groove 114 while it is non-parallel with the retainer 110. The lock 150 may be rotated, while the lock retaining portion 151 is in the groove 114, to rotate the relative positions of the major axis 158 and minor axis 159 with respect to the groove 114. Due to the size of the major axis 158, the rotation of the lock 150 will result in the lock retaining portion 151 becoming wedged within the groove 114 to secure the lock 150 in place relative to the retainer 110.
In one embodiment, the lock retaining portion 151 is shaped to provide a bi-stable structure, wherein the lock 150 is stable when substantially perpendicular—and free to slide in the groove 114—to the retainer 110. In such a perpendicular position, the lock 150 would extend from the retainer 110 and interfere with the imprinting. The lock 150 is also stable when substantially parallel—and unable to slide without substantial force relative to the groove 114—with the retainer 110. When in such a parallel position, the lock 150 does not extend from the retainer 110 sufficient to interfere with imprinting. In one implementation, the lock retaining portion 151 is an elliptical cylinder. In another implementation, illustrated in FIG. 3B, the lock retaining portion 151 includes one or more ridges 153. The ridges 153 provide a larger effective diameter than where the lock retaining portion 151 lacks ridges 153. In such an embodiment, the ridges engage the retainer 110 to secure the lock 150 when the lock 150 is positioned parallel to the retainer 110.
In one embodiment, the lock 150 has a ledge 154 bordering the lock deck 152 and extending from the lock deck 152 such that the ledge 154 is adjacent to the retainer body 111 when the lock 150 is parallel with the retainer 110. In one embodiment, illustrated in FIG. 3A, two ledges 154 are provided such that each ledge 154 abuts and runs perpendicular to the lock retaining portion 151. Each ledge 154 protrudes from the lock deck 152 to interfere with sides 113 of retainer 110 to ensure that first lock 150a and second lock 150b fasten at least one press piece 180 between the sides 113 of retainer 110. The ledge 154 may serve as a stop to limit rotation of the lock 150 with respect to the retainer 110. For example, the ledge 154 may prevent the lock 150 from rotating past the point where the major axis 158 is when the lock deck 152 is oriented in a first position to parallel retainer 110, and interference is created between each ledge 154 and sides 113 of retainer 110 to inhibit movement. When the lock deck 152 is oriented to be in a second position to be perpendicular to the design 182 and to retainer 110, movement is allowed. The lock deck 152 has a width, and, in one embodiment, the lock retaining portion 151 has a width that exceeds the width of lock deck 152. The width of lock deck 152 is less than the distance between the opposing grooves 114 to allow the lock 150 to rotate relative to the retainer 110.
The press piece 180 has a design 182 projecting in a first direction away from the retainer 110 and towards a surface to be imprinted (see FIG. 1C). A press piece 180 comprising a back 184 may be oriented in the retainer 110 so that the design 182 contacts the desired surface while the back 184 of the press piece 180 faces towards retainer 110 (see FIG. 5). As illustrated in FIG. 4A, the grip 119 projects from the retainer 110 in a second direction opposed to the first direction. Sides 113 of the retainer 110 project in the first direction. The grip 119 allows for manual positioning of imprinter 100 at a desired location. The grip 119 is approximately equidistant between sides 113 of retainer 110 and provides for imprinter 100 to be used comfortably and safely.
Referring now to FIG. 1C, sides 183 of press piece 180 extend in a second direction opposite to the first direction that the design extends along. Sides 183 of press piece 180 are configured to be inserted between sides 113 of retainer 110. FIG. 5 illustrates an embodiment when viewed from the surface to be imprinted. An embodiment formed of transparent material removes guesswork from positioning the imprinter to create impressions in a surface at a desired location because a decorator can view the position of at least one press piece 180 within the retainer 110 prior to applying force to the imprinter 100.
In one embodiment, the imprinting tool may include only a first lock 150a. The first lock 150a may be engageable at one end of the retainer 110, with the second end of the retainer 110 retaining the press pieces 180 such that a second lock 150b is not necessary to retain the press pieces 180.
In one embodiment, the first lock 150a and the second lock 150b are chiral, being non-superimposable mirror images of each other and are designed to only secure the retainer 110 from their respective ends. In another embodiment, the first lock 150a and the second lock 150b are identical and may be interchanged to secure the retainer 110 from either end.
In one embodiment, a lock 150 may positioned between two press pieces 180 such as to serve as a spacer. In such embodiment, the lock 150 does not extend from the retainer 110 sufficiently to leave an imprint when the imprinter 100 is used. Thus, the lock 150 may serve to additionally secure press pieces 180 other than from an end and may also serve as a spacer, such as where a decorator wishes to form works from letters on press pieces 180.
In one embodiment, the press piece 180 may be inserted into the retainer 110 with the design 182 facing outward, i.e. away from the retainer, or inward, i.e. disposed between the deck 181 and the retainer body 111. In this embodiment, storage of the press piece 180 with the design inwardly facing can protect the design 182 from damage, such as during travel. Further, press pieces 180 that are inserted into the retainer 110 facing inward may be used as spacers between outwardly facing press pieces 180 to provide spaces between imprinted designs.
In one embodiment, the retainer 110 includes a plurality of retaining portions. In this embodiment, a plurality of grooves 114 each for receiving a portion of the press piece 180 are disposed to permit rows of press pieces 180 to be stacked in the retainer 110. In such embodiment, imprinter 100 can imprint at least one design 182, and resulting impressions on a surface of a desired location can surpass the design 182 of the press piece 180 in height and width. In this embodiment, the retainer body 111 comprises pairs of grooves 114 parallel to each other. Press pieces 180 can be disposed horizontally and vertically relative to each other to permit rows and columns of imprinted designs.
A method of using imprinter 100 is now described. Referring to FIGS. 1-5, at least one press piece 180 with a design 182 is selected. Each press piece 180 is inserted into a retainer 110 to be oriented parallel to a desired location for imprinting. A first lock 150a and a second lock 150b are positioned on opposing ends 106 of the retainer 110. A tab-shaped portion of each lock of first lock 150a and second lock 150b is turned in a first position parallel to the design 182 to secure each press piece 180. A grip 119 is used to position imprinter 100 over a surface at a desired location. Force is applied to imprinter 100 so that the design 182 of at least one press piece 180 is impressed on the surface.
The imprinter described above provides several advantages. The decorator can readily imprint designs on the surface of a desired location accurately and with consistent results. A plurality of combinations of designs are achievable. The grip 119 and the retainer 110 allow for placement of designs directly on the surface without manually positioning the press piece at the desired location. The method of imprinting described above may be more sanitary as there may be less contact with the decorator's hands and higher precision of design location and angle. Embodiments comprising translucent materials may allow the decorator to see the surface at the desired location, reducing delay and improving decoration speed and quality.
With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for the sake of clarity.
The foregoing description of illustrative embodiments has been presented for purposes of illustration and of description. It is not intended to be exhaustive or limiting with respect to the precise form disclosed, and modifications and variations are possible in light of the above teachings or may be acquired from practice of the disclosed embodiments. It is intended that the scope of the invention be defined by the claims appended hereto and their equivalents.
