Container with a cover snapped to a base

a technology of a container and a base, which is applied in the field of containers, can solve the problems of hooks being disengaged from the lips, too firm to release, and the engagement of the snapping member may be too lost to seal the base, so as to reduce the height and material needed, strengthen the strength of the at least one recess, and shorten the snapping member

Benefits of technology

The present invention provides a container with a base and cover that is snapped together. The cover has a recess in its lateral face, and the base has a snapping member with a protrusion that engages with the recess to connect the cover to the base. This design reinforces the strength of the recess, reduces the size of the snapping member, and saves material and cost. The container is stable and prevents deformation, even when being squeezed. Additionally, the engagement parts are located on the lateral sides of the base and cover, reinforcing the overall strength of the container. This design also allows for a thinner cover, meeting market demand for thin and low-profile containers.

Problems solved by technology

However, this snapping engagement the snapping engagement may be too lose to seal the base, or may be too firm to release.
The hooks may also be disengaged from the lips due to the food in the container is heavy or the way that the users to gran the cover improperly.
If the hooks have an exaggerated curvature or the width of the lips is not properly set, or the hooks are too big when comparted with the recesses of the ridges.
The friction between the hooks and lips will be significant so that the cover is difficult to be opened or even deforms the cover or the base.
If there are tolerances between the male and female parts, the resistance is significant so that the cover is difficult to close and to open relative to the base.
Because the existed molding technology, it is difficult to form the male parts on lateral sides of the base.

first embodiment

[0033]FIGS. 3 and 4 show the container of the present invention.

[0034]The snapping members 13 of the base 1 are bent by the bending portion 134 which is connected to the reception area 14. As shown in FIG. 3, the protruded area 135 of the protrusion 132 is integrally formed with the protrusion 132 and can be made by plastic or paper, so that the protruded area 135 is strong enough and is not deformed when the protrusion 132 is slightly force-fitted in the recess 23.

[0035]When the cover 2 is mounted to the base 1, the user can press the recessed portion 133 of the snapping member 13 to bend the snapping member 133 by the bending portion 134 so as to engage the protrusion 132 with the recess 23. When removing the cover 2 from the base 1, the protrusion 132 is disengaged from the recess 23 by pulling the extension portion member 131.

[0036]It is noted that when opening the cover 2 relative to the base 1 to access the food in the container, the user simply separates the protrusions 132 o...

second embodiment

[0041]FIG. 7 shows the container of the present invention, wherein each snapping members 13 includes multiple protrusions 132.

[0042]The differences between the second embodiment and the first embodiment are that the base 1 includes two elongate snapping members 13 respectively formed on two sides thereof, and each snapping member 13 includes multiple protrusions 132. The number of the protrusions 132 of the snapping members 13 is the same as the number of the recesses 23, so that the protrusions 132 are engaged with the recesses 23 correspondingly.

third embodiment

[0043]FIG. 8 shows the handle 26 of the container of the present invention, and FIG. 9 shows the container of the present invention is equipped with the handle 26.

[0044]The handle 26 includes a hole 261 formed through each of two ends thereof. A grip portion 262 is formed between the two ends of the handle 26. The protrusions 132 of two snapping members 13 are engaged with the two holes 261 of the handle 26. The two protrusions 132 connected with the handle 26 are engaged with the recesses 23 corresponding thereto. The users may hold the grip portion 262 to carry the container.

[0045]The container can be a rectangular or round container to include a rectangular or round base 1 and cover 2. Of course, the base 1 and the cover 2 can be shaped to include a curve periphery or multiple sides.

[0046]The recesses 23, the snapping members 13 and the protrusions 132 can be modified to include any size, number and arrangement. For examples, the container may include multiple pairs snapping memb...

Abstract

A container includes a base and a cover which is snapped to the base. The cover includes at least one recess defined in lateral face thereof. The base includes a peripheral wall which has a reception area. The reception area includes a stop wall that extends from the peripheral wall, and a snapping member extends from the reception area and includes a protrusion. The at least one recess includes a wide top opening and a narrow bottom. The protrusion is shaped to be engaged with the at least one recess to connect the cover to the base. The base includes stop wall which reinforces the base strength to avoid from being deformed.

Description

BACKGROUND OF THE INVENTION1. Fields of the Invention[0001]The present invention relates to a container, and more particularly, to a container with a cover which is snapped to a base.2. Descriptions of Related Art[0002]The conventional containers are made by plastic or paper-related material, wherein the containers with a cover that is able to seal the base to keep food fresh are welcomed in the marked. Especially for those container made by plastic are able to prevent liquid from splitting out and are used in different ways.[0003]An important feature of this type of plastic-made containers is the stability and reliability of the cover that is connected to the base. For the conventional plastic-made containers generally includes hooks formed along sides of the cover, and the base includes lips which are hooked by the hooks. However, this snapping engagement the snapping engagement may be too lose to seal the base, or may be too firm to release. For the first situation, the hooks sim...
