Referring now to the drawings, specific embodiments of the present invention will be described in detail. What has been described herein is merely a preferred embodiment in accordance with the present invention, and those skilled in the art will appreciate that other ways of implementing the present invention on the basis of the preferred embodiment will also fall within the scope of the present invention.
The utility model provides a container, this container can be used to hold and preserve liquid or solid-state food etc.. It will be appreciated that the container according to the invention may be made of a material having a certain elasticity, such as an ultra-thin injection moulded material, a thicker plastic, etc., and that materials such as metal or plastic may be used. The container according to the present invention is not limited to holding food, and may be a container for holding any article. The container according to the present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 shows a container 10 according to a preferred embodiment of the invention, which has a receiving space 11 enclosed by a container wall and a container bottom. It should be noted that the following description will be made with reference to the housing chamber 11, for example, inward in the direction toward the housing chamber 11 and outward in the direction away from the housing chamber 11. The accommodation chamber 11 forms an opening at the top communicating with the outside. The user can put food into the receiving chamber 11 through the opening, or take out the food from the receiving chamber 11 or eat it directly.
As shown in fig. 2, in order to improve deformation resistance, the container 10 is provided with a boss portion 12 protruding upward on an outer peripheral side of the opening, and a first recess 13 is provided on an outer peripheral side of the boss portion 12. The boss portion 12 is a hollow structure and is formed in a substantially inverted U shape with an opening facing downward. The first groove 13 is formed in a right U shape opening upward. That is, the opening of the boss portion 12 is oriented opposite to the opening of the accommodation chamber 11, while the opening of the first recess 13 is oriented the same as the opening of the accommodation chamber 11. The boss portion 12 and the first groove 13 extend around the entire circumference of the container 10.
The boss portion 12 and the first recess 13 may be structures continuously formed outward from a thin wall similar to the container wall. This can reduce the weight of the container and save material. Preferably, the outer sidewall 122 of the boss portion 12 extends downward to form the inner sidewall 133 of the first groove 13, so that the boss portion 12 and the first groove 13 are continuously formed without other structures therebetween. Thus, the boss portion 12 and the first groove 13 have a common side wall. This allows the container 10 to be compact. Wherein the common side wall may be angled from 0 to 20 ° from vertical. It will be appreciated that when a container according to the invention is made of a plastic material, it is preferably made by an injection moulding process. Demolding after injection molding is facilitated by the provision of the common side wall being tapered outwardly in a direction extending outwardly from the outer periphery of the container.
Preferably, the boss portion 12 may be configured to gradually decrease in width along the projecting direction thereof. In other words, the boss portion 12 may have a substantially frustum-shaped vertical cross section.
With continued reference to fig. 2, the upper edge of the outer sidewall 132 of the first recess 13 defines a staggered reference line AX for the container 10. The difference in height between the top surface 121 of the boss portion 12 and the staggered reference line AX is H1. The opening width of the first groove 13 is W1. According to the present invention, the container is constructed such that the ratio of H1 to W1 is not less than 0.5. Preferably, the ratio of H1 to W1 may be greater than or equal to (i.e., not less than) 1. When the container according to the present invention is used for packaging food such as cake, the ratio of H1 to W1 can reach 50 at maximum. With this arrangement, when the container 10 is tilted during eating or moving, and the liquid therein is spilled via the upper edge of the boss 12, the liquid is directly spilled outside the first groove 13, and is not easily accumulated in the first groove 13. The composite material also has good blocking and anti-accumulation effects on solid food residues. And conversely, if any liquid or solid food remains in the first recess, it will not be poured back into the container. This can reduce the possibility of contamination of the food in the accommodating chamber 11 with outside bacteria, and greatly ensure food safety.
In addition, the boss portion 12 and the first groove 13 form a composite staggered structure. And the difference in height between the upper edge of the boss portion 12 and the upper edge of the first groove 13 is large, the height of the common side wall of the boss portion 12 and the first groove 13 is large, which results in good resistance to deformation of the container 10 at the location of the mating structure. This is advantageous for the safety of the food container during transportation and after the food is contained therein. The wall thickness of the container can be reduced to some extent while maintaining sufficient resistance to deformation. For example, at present this type of container with a wall thickness above 0.5mm, according to the present invention, the wall thickness of the container wall can be reduced to 0.35mm, even 0.3mm, still maintaining sufficient deformation resistance, but saving at least 30% of the material, thus reducing the production costs. Therefore, according to the utility model discloses a container can use various ultra-thin forming technique preparation shaping.
The height difference may also reduce the possibility that the user's mouth or hand touches the outer side wall 132 of the first recess 13 when contacting the boss portion 12 (e.g., a use scenario of hand contact when taking a container, mouth contact when drinking soup, or the like). It will be appreciated that the edges of the outer side wall 132 of the first groove 13 are sharp due to the thin-walled construction. In contrast, the upper edge of the boss portion 12 is formed to be rounded, without risk of scratching. The edge of the outer side wall 132 does not need to be specially bent or passivated, so that the process is simplified.
Fig. 3 shows a modification of the above preferred embodiment. In this variant, the opening of the container 10a is provided with a laterally outward mouth edge 15 a. The boss portion 12a is provided projecting upward from the outer edge of the mouth edge 15 a. The height of the lip 15a may be arbitrary. It is preferable that the height of the mouth edge 15a is not lower than the lower edge of the first groove 13 a. The provision of the rim 15a may further enhance the structural strength of the container 10a and in particular may further enhance its resistance to deformation when subjected to lateral forces.
Fig. 4 shows another modification of the above preferred embodiment. In this modification, the top surface 121b of the boss portion 12b is provided with the weld line 124 projecting upward. The weld line 124 extends in a ring shape along the circumferential direction of the housing chamber. The opening of the receiving cavity may be covered with a cover film or sheet, for example, to form a seal to the receiving cavity, thereby reducing the use of a cap. The cover film or sheet may be fixedly attached to the weld line 124 by welding.
In fig. 4, the weld line 124 is provided in two passes, which have a substantially triangular vertical cross section. However, it is understood that in other embodiments, the weld line 124 may be provided in one, three, or more passes, and/or the vertical cross-section of the weld line 124 may be configured in other shapes, such as semicircular, rectangular, trapezoidal, or any other suitable shape, depending on the width of the top surface 121b of the boss portion 12 b.
Preferably, the projected height of the weld line 124 is no greater than 1mm, and/or the width of the weld line 124 is no greater than 2 mm. In this way, while ensuring that the weld line 124 can be welded to the cover film or sheet, it is possible to make it moderate in size without affecting the structure of the boss portion 12b, and to make the joining force with which the seal is maintained between the weld line 124 and the cover film or sheet small so as to manually peel off the cover film or sheet when opening is required. The container is particularly suitable for containing foods such as milk tea, soybean milk and the like.
