Definitions
- the present invention relates to containers, and in particular, to a tamper evident design for containers.
- Containers can be constructed with various structures and sizes. Two common container structures include clamshell containers and multi-piece containers. Clamshell containers are containers that mimic the form and function of a clamshell. Clamshell containers include a base portion and a cover portion that are attached to one another with a hinge. Multi-piece containers are containers that include a base portion and a cover portion that are separate pieces designed to fit together. Typically, both clamshell containers and multi-piece containers have some form of closure that is capable of holding the cover portion on the base portion when the container is closed. Different types of closures can be used, including self-locking tabs, snaps, or screw tops. Containers can also be held together with means other than closures. These means can include using frictional forces to hold container pieces together, heat sealing the container pieces together, or using staples, adhesives, or labels to hold the container pieces together.
- Containers are typically secured using standard closures that allow a user to open and close the container with no consequence. Containers can also be secured with tamper evident or tamper proof closures. These types of closures include a feature that will make it obvious that the container has been opened. A container with a tamper evident or a tamper proof closure will be irreversibly altered when the container is opened for the first time.
- a tamper evident container includes a first container portion, a second container portion, and a tamper evident closure.
- the tamper evident closure includes a first snap connected to the first container portion, a second snap connected to the second container portion, a tear strip connected to the second snap, and a third snap connected to the tear strip.
- the first snap is placed in a cavity in the second snap
- the third snap is placed in a cavity in the first snap.
- the tear strip faces outward from the tamper evident container.
- FIG. 1 is a perspective view of a tamper evident container in a closed position.
- FIG. 2 is a perspective view of the tamper evident container of FIG. 1 in an open position.
- FIG. 3A is a side elevation view of the tamper evident container of FIG. 1 in an open position.
- FIG. 3B is a top plan view of the tamper evident container of FIG. 1 in an open position.
- FIG. 4A is a side elevation view of the tamper evident container of FIG. 1 in a partially closed position.
- FIG. 4B is a cut-away side elevation view of the tamper evident container of FIG. 1 in a partially closed position.
- FIG. 5A is a side elevation view of the tamper evident container of FIG. 1 in a closed position.
- FIG. 5B is a cut-away side elevation view of the tamper evident container of FIG. 1 in a closed position.
- FIG. 6 is a cut-away perspective view of the tamper evident container of FIG. 1 in a closed position.
- the present invention relates to a tamper evident design for containers.
- Containers are used in many industries as a form of packaging for products that are commercially available.
- To indicate when someone has opened a package some form of tamper evident or tamper proof means is used.
- a tamper evident indicator will indicate that the package has been opened, so that someone purchasing or using the product can ensure that the package includes all of the necessary contents and is safe to use.

- Hinge 38 is located on rear side 24 of tamper evident container 20 when tamper evident container 20 is in a closed position.
- first container portion 34 fits on second container portion 36 .
- first container portion 34 is attached to first snaps 42 A and 42 B.
- Second container portion 36 is attached to second snaps 44 A and 44 B.
- Second snaps 44 A and 44 B are attached to tear strips 46 A and 46 B along perforated lines 54 A and 54 B, respectively. Tear strips 46 A and 46 B are attached to third snaps 48 A and 48 B along perforated lines 56 A and 56 B, respectively.
- tamper evident closures 40 A and 40 B are located on front side 22 of tamper evident container 20 .
- tamper evident closures 40 A and 40 B may be located on any side of container 20 .
- Tamper evident closure 40 A is formed by fitting first snap 42 A, second snap 44 A, tear strip 46 A and third snap 48 A together.
- Tamper evident closure 40 B is formed by fitting first snap 42 B, second snap 44 B, tear strip 46 B, and third snap 48 B together.
- tamper evident closures 40 A and 40 B are positioned so that tear strips 46 A and 46 B face outward of tamper evident container 20 .
- Tear strips 46 A and 46 B are attached to first snaps 44 A and 44 B and second snaps 48 A and 48 B along perforated lines 54 A and 54 B and perforated lines 56 A and 56 B, respectively.
- perforated lines 54 A and 54 B and perforated lines 56 A and 56 B separate so that tear strips 46 A and 46 B can be removed from tamper evident container 20 .
- tamper evident closures 40 A and 40 B can be opened and closed.
- Tamper evident closures 40 A and 40 B create a container that is tamper evident.
- a user To open tamper evident container 20 , a user must grab tear strips 46 A and 46 B and pull them away and remove them from tamper evident container 20 . Once tear strips 46 A and 46 B are removed from tamper evident container 20 , a user can open and close tamper evident closures 40 A and 40 B. This allows a user to open and close tamper evident container 20 an infinite number of times, even if tamper evident container 20 will no longer have tamper evident features after it is opened for the first time. Tamper evident container 20 can be assembled by hand, which allows someone to use the container to package his or her own products.
- Tamper evident container 20 can be used in a variety of different ways. First, tamper evident container 20 can be used to package food. Having a tamper evident package for food is advantageous, as consumers can ensure that the food has not been tampered with prior to purchasing it. Second, tamper evident container 20 can be used to package products. Having a tamper evident package for products can ensure consumers that all of the parts are in the package and that the product has not been tampered with prior to purchasing it.

- First container portion 34 includes rim 58 on an outer periphery.
- Second container portion 36 includes rim 60 on an outer periphery.
- First container portion 34 is connected to second container portion 36 along hinge 38 .
- Hinge 38 has a curved shape and can bend when tamper evident container 20 is closed.
- First flanges 50 A and 50 B are attached to first container portion 34 .
- Second flanges 52 A and 52 B are attached to second container portion 36 .
- First flanges 50 A and 50 B have substantially rectangular shapes.
- First snaps 42 A and 42 B are located on first flanges 50 A and 50 B.
- First flanges 50 A and 50 B extend horizontally outward of first snaps 42 A and 42 B to provide a surface that can be grasped by a user to open and close tamper evident container 20 .
- First snaps 42 A and 42 B have a substantially rectangular shape and project upwards from first flanges 50 A and 50 B.
- First snaps 42 A and 42 B have a cavity formed on the inside of the upward projection that can be accessed on the bottom side of first flanges 50 A and 50 B.
- first snaps 42 A and 42 B can have any shape, including but not limited to, a square shape, a circular shape, or an oval shape.
- Second flanges 52 A and 52 B also have substantially rectangular shapes. Second snaps 44 A and 44 B, tear strips 46 A and 46 B, third snaps 48 A and 48 B, perforated lines 54 A and 54 B, and perforated lines 56 A and 56 B are located on first flanges 52 A and 52 B. Second flanges 52 A and 52 B extend horizontally outward of second snaps 44 A and 44 B and third snaps 48 A and 48 B to provide a surface that can be gasped by a user to open and close tamper evident container 20 . Second snaps 44 A and 44 B are attached to tear strips 46 A and 46 B along perforated lines 54 A and 54 B, respectively.
- Tear strips 46 A and 46 B are attached to third snaps 48 A and 48 B along perforated lines 56 A and 56 B, respectively.
- Second snaps 44 A and 44 B have a substantially rectangular shape and project downwards from second flanges 52 A and 52 B.

- Perforated lines 54 A and 54 B and perforated lines 56 A and 56 B are straight lines that run across second flanges 52 A and 52 B. Perforated lines 54 A and 54 B and perforated lines 56 A and 56 B can be made from perforations of any suitable size. Tear strips 56 A and 56 B have a square edge on a first end and a rounded edge on a second end. The square edge of tear strips 56 A and 56 B is in line with second snaps 44 A and 44 B and third snaps 48 A and 48 B. The rounded edge of tear strips 56 A and 56 B extends horizontally outward past second snaps 44 A and 44 B and third snaps 48 A and 48 B.
- tear strips 56 A and 56 B can have alternate shapes and can extend outward from second snaps 44 A and 44 B and third snaps 48 A and 48 B in various manners.
- Tamper evident container 20 is manufactured in the open position, as seen in FIGS. 3A-3B . Tamper evident container 20 is manufactured using common container and packaging manufacturing techniques. Manufacturing tamper evident container 20 in the open position allows tamper evident container 20 to be stacked in a substantially flat manner for shipping. This allows multiple containers to be shipped in a single box, which saves space and cost. Being able to stack tamper evident container 20 while it is in the open position also saves space when storing tamper evident container 20 .
- FIGS. 4A-4B show tamper evident container 20 in a partially closed position.
- FIG. 4A is a side elevation view of tamper evident container 20 in a partially closed position.
- FIG. 4B is a cut-away side elevation view of tamper evident container 20 in a partially closed position.
- Tamper evident container 20 includes first container portion 34 , second container portion 36 , hinge 38 , first rim 58 , second rim 60 , first snap 42 , second snap 44 , perforated line 54 , tear strip 46 , perforated line 56 , and third snap 48 .
- First container portion 34 includes first rim 58
- second container portion 36 includes second rim 60 .
- First container portion 34 is connected to second container portion 36 along hinge 38 . In a partially closed position, first container portion 34 is folded to fit on second container portion 36 .
- First rim 58 of first container portion 34 fits onto second rim 60 of second container portion 36 to close tamper evident container 20 .
- first snap 42 can be placed in the cavity of second snap 44 .
- First snap 42 fits in second snap 44 so that the two portions can be held together with friction forces when there is no outside pressure being applied to them.
- first snap 42 can be removed from second snap 44 so tamper evident container 20 can be opened.
- First snap 42 and second snap 44 act as a typically snap-lock feature that can be closed and opened with no consequence.
- FIGS. 5A-5B show tamper evident container 20 in a closed position.
- FIG. 5A is a side elevation view of tamper evident container 20 in a closed position.
- FIG. 5B is a cut-away side elevation view of tamper evident container 20 in a closed position.
- Tamper evident container 20 includes first container portion 34 , second container portion 36 , hinge 38 , first rim 58 , second rim 60 , first snap 42 , second snap 44 , perforated line 54 , tear strip 46 , perforated line 56 , and third snap 48 .
- tear strip 46 and third snap 48 can be folded around the snap-lock closure consisting of first snap 42 and second snap 44 .
- Third snap 48 can then be placed in the cavity of first snap 42 .
- Third snap 48 is designed to have a tight fit with the cavity of first snap 42 so that there are no voids between the two snaps when tamper evident container 20 is closed. Having a tight fit between third snap 48 and first snap 42 makes it very difficult, if not impossible, for tamper evident container 20 to be opened without permanently altering tamper evident closure 40 or tamper evident container 20 .
- third snap 48 in first snap 42 leaves tear strip 46 facing outwards from tamper evident container 20 .
- perforated line 54 and perforated line 56 bend so that tear strip 46 can face outwards. Bending perforated line 54 and perforated line 56 weakens them so that tear strip 46 can be removed easily.
- a user can grab the rounded edge of tear strip 46 and pull tear strip 46 outwards and away from tamper evident container 20 .
- perforated line 54 and perforated line 56 break apart. This allows for the easy removal of tear strip 46 .
- tamper evident closure 40 can be opened by pulling first snap 42 out of the cavity of second snap 44 .
- Third snap 48 remains in the cavity of first snap 42 when first snap 42 is removed from second snap 44 .
- Third snap 48 is designed to fit tightly in first snap 42 with no voids so that tamper evident container 20 can not be opened without first removing tear strip 46 .
- the tight fit between third snap 48 and first snap 42 reduces the potential of someone being able to open the container with a sharp or pointed object. It also reduces the potential of someone being able to open tamper evident container 20 without first removing tear strips 46 A and 46 B.
- Tamper evident closure 40 is a closure that can be closed for the first time by a user to create a tamper evident seal. After it is opened for the first time and tear strip 46 is removed, tamper evident closure 40 operates like a typical snap-lock closure so that tamper evident container 20 can be opened and closed an infinite number of times.
- Tamper evident closure 40 is advantageous for this reason, as it allows a user to utilize a tamper evident closure on a container while allowing the container to be opened and closed an infinite number of times after it is opened for the first time. Tamper evident container 20 is permanently altered when tear strip 46 is removed, but the permanent alteration does not prevent a user for opening and closing the container after that point.
- FIG. 6 is a cut-away perspective view of tamper evident container 20 in a closed position.

Abstract
Description
- The present invention relates to containers, and in particular, to a tamper evident design for containers.
- Containers can be constructed with various structures and sizes. Two common container structures include clamshell containers and multi-piece containers. Clamshell containers are containers that mimic the form and function of a clamshell. Clamshell containers include a base portion and a cover portion that are attached to one another with a hinge. Multi-piece containers are containers that include a base portion and a cover portion that are separate pieces designed to fit together. Typically, both clamshell containers and multi-piece containers have some form of closure that is capable of holding the cover portion on the base portion when the container is closed. Different types of closures can be used, including self-locking tabs, snaps, or screw tops. Containers can also be held together with means other than closures. These means can include using frictional forces to hold container pieces together, heat sealing the container pieces together, or using staples, adhesives, or labels to hold the container pieces together.
- Containers are typically secured using standard closures that allow a user to open and close the container with no consequence. Containers can also be secured with tamper evident or tamper proof closures. These types of closures include a feature that will make it obvious that the container has been opened. A container with a tamper evident or a tamper proof closure will be irreversibly altered when the container is opened for the first time.
- According to the present invention, a tamper evident container includes a first container portion, a second container portion, and a tamper evident closure. The tamper evident closure includes a first snap connected to the first container portion, a second snap connected to the second container portion, a tear strip connected to the second snap, and a third snap connected to the tear strip. In a closed position, the first snap is placed in a cavity in the second snap, and the third snap is placed in a cavity in the first snap. Also in a closed position, the tear strip faces outward from the tamper evident container.

Containers are used in many industries as a form of packaging for products that are commercially available. To indicate when someone has opened a package, some form of tamper evident or tamper proof means is used. A tamper evident indicator will indicate that the package has been opened, so that someone purchasing or using the product can ensure that the package includes all of the necessary contents and is safe to use.

Manufacturing tamperevident container 20 in the open position allows tamperevident container 20 to be stacked in a substantially flat manner for shipping. This allows multiple containers to be shipped in a single box, which saves space and cost. Being able to stack tamperevident container 20 while it is in the open position also saves space when storing tamperevident container 20. -
FIGS. 4A-4B show tamperevident container 20 in a partially closed position.FIG. 4A is a side elevation view of tamperevident container 20 in a partially closed position.FIG. 4B is a cut-away side elevation view of tamperevident container 20 in a partially closed position. Tamperevident container 20 includesfirst container portion 34,second container portion 36,hinge 38,first rim 58,second rim 60,first snap 42,second snap 44, perforatedline 54,tear strip 46, perforatedline 56, andthird snap 48. -
First container portion 34 includesfirst rim 58, andsecond container portion 36 includessecond rim 60.First container portion 34 is connected tosecond container portion 36 alonghinge 38. In a partially closed position,first container portion 34 is folded to fit onsecond container portion 36. First rim 58 offirst container portion 34 fits ontosecond rim 60 ofsecond container portion 36 to close tamperevident container 20. - After
first container portion 34 has been placed onsecond container portion 36,first snap 42 can be placed in the cavity ofsecond snap 44.First snap 42 fits insecond snap 44 so that the two portions can be held together with friction forces when there is no outside pressure being applied to them. When outside pressure is applied,first snap 42 can be removed fromsecond snap 44 so tamperevident container 20 can be opened.First snap 42 andsecond snap 44 act as a typically snap-lock feature that can be closed and opened with no consequence. -
FIGS. 5A-5B show tamperevident container 20 in a closed position.FIG. 5A is a side elevation view of tamperevident container 20 in a closed position.FIG. 5B is a cut-away side elevation view of tamperevident container 20 in a closed position. Tamperevident container 20 includesfirst container portion 34,second container portion 36,hinge 38,first rim 58,second rim 60,first snap 42,second snap 44, perforatedline 54,tear strip 46, perforatedline 56, andthird snap 48. - To fully close tamper
evident container 20,tear strip 46 andthird snap 48 can be folded around the snap-lock closure consisting offirst snap 42 andsecond snap 44.Third snap 48 can then be placed in the cavity offirst snap 42.Third snap 48 is designed to have a tight fit with the cavity offirst snap 42 so that there are no voids between the two snaps when tamperevident container 20 is closed. Having a tight fit betweenthird snap 48 andfirst snap 42 makes it very difficult, if not impossible, for tamperevident container 20 to be opened without permanently altering tamperevident closure 40 or tamperevident container 20. - Placing
third snap 48 infirst snap 42 leaves tearstrip 46 facing outwards from tamperevident container 20. Whentear strip 46 andthird snap 48 are folded,perforated line 54 andperforated line 56 bend so thattear strip 46 can face outwards. Bendingperforated line 54 andperforated line 56 weakens them so thattear strip 46 can be removed easily. To removetear strip 46, a user can grab the rounded edge oftear strip 46 and pulltear strip 46 outwards and away from tamperevident container 20. Whentear strip 46 is pulled outward and away from tamperevident container 20, perforatedline 54 andperforated line 56 break apart. This allows for the easy removal oftear strip 46. Oncetear strip 46 is removed, tamperevident closure 40 can be opened by pullingfirst snap 42 out of the cavity ofsecond snap 44.Third snap 48 remains in the cavity offirst snap 42 whenfirst snap 42 is removed fromsecond snap 44. -
Third snap 48 is designed to fit tightly infirst snap 42 with no voids so that tamperevident container 20 can not be opened without first removingtear strip 46. The tight fit betweenthird snap 48 andfirst snap 42 reduces the potential of someone being able to open the container with a sharp or pointed object. It also reduces the potential of someone being able to open tamperevident container 20 without first removingtear strips evident closure 40 is a closure that can be closed for the first time by a user to create a tamper evident seal. After it is opened for the first time andtear strip 46 is removed, tamperevident closure 40 operates like a typical snap-lock closure so that tamperevident container 20 can be opened and closed an infinite number of times. Tamperevident closure 40 is advantageous for this reason, as it allows a user to utilize a tamper evident closure on a container while allowing the container to be opened and closed an infinite number of times after it is opened for the first time. Tamperevident container 20 is permanently altered whentear strip 46 is removed, but the permanent alteration does not prevent a user for opening and closing the container after that point. -
